AUTOMATIC READING AND WRITING MECHANISM FOR BANK PASSBOOKS AND THE
LIKE
Abstract
Relates to apparatus for automatically reading from and writing
upon relatively thick documentary or multi-page material, such as
bank passbooks and the like, and particularly with regard to
magnetic data storing stripes secured to covers or other surface
portions of such material. The mechanism includes an abuttable edge
serving as a positioning guide for the passbook and a magnetic
transducing read head arranged to compressingly engage the magnetic
stripe and either magnetically read from or write data thereupon as
it is moved along the stripe. Also included in the mechanism is a
passbook gripping device which functions before travel of the
transducing head to clamp onto the introduced edge portion of the
passbook and pull it firmly into abutment with the positioning
guide, thereby bringing the magnetic stripe into colinear
relationship with the path of travel of the transducing head.
Additionally, included in the mechanism is a provision for sensing
the proper positioning of the introduced edge of the passbook and
generating an electrical signal for initiating the movement of the
transducing head when such position is attained. Additional
features include provisions for pressing the moving transucing head
into engagement with the magnetic stripe after it has accelerated
to a constant rate of speed and for providing return movement of
the head to an initial position.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates generally to transducing equipment for
magnetically recording and sensing information on documentary
material and particularly to such equipment designed to perform its
transducing functions on relatively thick, compressible documents,
such as bank passbooks and the like.
2. Description of the Prior Art
Identification instrumentalities such as credit cards, bank
passbooks and the like are of common knowledge and in widespread
use and have been generally issued to customers of financial
institutions, such as banks, to provide identification as well as
efficient service and to maintain accurate financial transactions
between the customers and the institution. Accounting equipment has
been designed to accept bank passbooks for making accounting
entries therein and exemplary thereof is the accounting machine
disclosed in the U. S. Pat. to Racz No. 2,468,408 (FIGS. 4, 24 and
25) of common ownership herewith. To protect as well as to speed up
financial transaction between the customers and the institution,
magnetic stripes have been bonded to or printed upon relatively
thin bank checks and ledger sheets and the like in such a manner
that the payee's name and account number are both visible to the
eye and machine writable and readable.
However, where thicker and more compressible documentary material
is concerned, such as multi-page bank passbooks and the like having
relatively thick protection covers, a problem arose because the
transducing tip of a magnetic read/write head will have to
physically engage the magnetic material to assure complete, strong
signal sensing and writing of data thereon. Such engagement not
only creates the problem of wear of the transducing head and the
magnetic material forming the stripe but also the proper
positioning of the thicker document or book for the transducing
operation. If the passbook is not properly positioned within the
automatic reading and writing equipment then the consequent
misalignment of the magnetic stripe with the direction of travel of
the transducing head is likely to result in faulty or erroneous
transfer of information either to or from the stripe.
In view of the difficulties and problems described above, it is
evident that an improvement is needed which will overcome these
problems and at the same time minimize the unavoidable effect of
wear of the transducing heads and thereby extend their lifetime
usefulness. It is also apparent that for thick, compressible record
media it is necessary to provide continuous substantially uniform
contact between the magnetic head and the stripe during transducing
operations regardless of any irregularity in the condition of the
passbook or the like, or the manner of its manual introduction into
the reading apparatus.
SUMMARY OF THE INVENTION
It is accordingly an important object of the invention to provide
an improved method of and apparatus for machine reading of data
carried on relatively thick, compressible materials and more
specifically the covers of multi-page books such as bank passbooks
and the like.
Another important object of the invention is to provide an improved
magnetic stripe patch for securement to relatively thick,
compressible articles and in such a manner as to reduce the wear on
a transducing head engageable with the stripe as it is moved
therealong.
It is another important object of the invention to provide an
accurate, reliable and durable method of and apparatus for
transducing information from a magnetic stripe carried on
relatively thick, compressible documentary material, while assuring
strong transduced signals even as wear occurs.
Another important object of the invention is to provide improved
apparatus for machine reading of magnetic stripes bearing
transducable coded information.
A further important object of the invention is to provide improved
apparatus for machine reading of and writing upon magnetic stripes
secured to relatively thick support members, such as the covers of
bank passbooks and the like, and which assures that the transducing
head of the apparatus applies a continuous substantially uniform
rubbing action on the magnetic stripe as relative movement occurs
between the head and the magnetic stripe.
In carrying out the objects of this invention, the present
invention contemplates a novel method of and apparatus for sensing
magnetic impulses either from or upon a magnetic stripe and for
recording such impulses thereon, the stripe being secured to a
relatively thick, yielding documentary medium requiring actual
engagement of the transducing head with the stripe as relative
movement occurs therebetween. Typical of such documentary media are
the relatively soft compressible covers of books and the like and
particularly the protective covers of financial institutional
passbooks and the like. The present invention assures satisfactory
transducement of data between the head and the magnetic material on
the stripe by automatically properly positioning the stripe with
respect to the path of travel of the head and by automatically
compressibly engaging the head with the stripe with the same degree
of pressure throughout the movement of the head along the stripe.
More specifically, as illustrated herein, the magnetic stripe is
secured to the cover of a bank passbook, or other similar financial
bookkeeping instrument, so that its longitudinal axis extends, when
read by the transducing read head, generally coextensive with the
path of travel of the latter.
To provide a desired orientation of the magnetic stripe to the path
of travel of the read head, the transducing apparatus of which the
head is a part is provided with an abutting wall or edge guide with
which one edge of the cover of the book bearing the stripe is
brought up against. The read head is mounted for travel in the
illustrating embodiment of the invention in parallel relation to
this edge guide and such that the longitudinal axis of the stripe
extends colinear to the path of travel of the head. A provision is
incorporated in the apparatus for automatically assuring this
relationship before head travel and for signaling such condition to
initiate the head travel. A feature of the transducing apparatus is
the provision which yieldingly forces the read head into engagement
with the magnetic stripe and maintains such pressure on the head
during its travel over the stripe. Another feature of the invention
concerns the dimensional relation of the stripe and the read head,
the latter having a wider extent than the stripe sufficient to
straddle the latter throughout its engaging stroke.
These and other objects, advantages and aspects of the present
invention will be more clearly understood from the following
description of the drawings, specification and appended claims.

DESCRIPTION OF A PREFERRED EMBODIMENT
Referring to the drawings wherein like reference characters
designate similar or identical elements in the FIgures, and with
initial reference to FIG. 6, there is shown a corner portion of a
record medium 10, such as a bank passbook, to which is affixed a
magnetic stripe label or patch 12, the construction of which will
be described in more detail hereinafter and is similar to that
described in the patent application of Hilliard R. DiVeto, Ser. No.
186,203 filed Oct. 4, 1971. and of common ownership herewith, now
U.S. Pat. No. 3,753,255. The magnetizable data storing section of
the patch is indicated at 14, and as illustrated herein it forms a
narrower upper layer of the patch 12 extending in close proximity
to the leading edge 16 of the passbook and parallel thereto. The
magnetic stripe 14 provides the area of the passbook where the
stored magnetic information, such as account number, balance and
passbook line number are recorded.
A magnetic read/write station generally indicated at 18 in FIGS. 2
and 3 is constructed so as to be adjusted to accept covers of
passbooks of various sizes and thicknesses as well as of different
styles. To compensate for their different thicknesses as well as to
assure accurate transducing of data between a magnetic transducing
head 20 and the magnetic stripe 14 of an introduced passbook, the
head of the station 18 is resiliently mounted so that it may be
pressed into contact with the magnetic stripe 14 of the patch 12
for the major portion of its predetermined path of travel. In the
description which follows, it will be noted that the patch 12 is
secured or bonded to the passbook 10 such that when the book is
properly placed into a readable or writable position with respect
to the transducing head 20, the magnetic stripe carried by the
patch will align with the path of travel of the head.
As shown in the schematic view of FIG. 1, the read/write station 18
includes, in general, a support or base plate 22 upon which the
magnetic transducing head 20 is mounted for to and fro movement
over the magnetic stripe 14 on the leading edge portion of a
passbook 10 introduced into the station, as indicated in dotted
outline. The base plate 22 may be shaped along its forward edge to
form an entrance or mouth for the leading edge of a passbook and
engageable with the leading edge is a gripper mechanism for
properly positioning this edge and the magnetic stripe 14 with
reference to an edge guide forming part of the mouth. To this end,
the gripper mechanism is constructed in such a manner as to have a
compound motion, first gripping the leading edge 16 of the passbook
and then moving in a retracting direction to pull the leading edge
fully and firmly into abuting engagement with an edge guide which,
in the illustrated embodiment of the invention, may take the form
of a bar 26. The edge guide or bar 26 is interrupted for part of
its length to permit the protrusion of certain operating elements
of the gripper mechanism therethrough and beyond its front face for
gripping the leading edge of the passbook. The dimensions of the
mouth should be large enough to accommodate bank passbooks 10 of
various sizes and styles, which are in common use, such as
described in the aforesaid referenced DiVeto patent application.
Thus, as a result of the accommodation provided by the mouth, and
the operating elements associated therewith, when a passbook is
fully inserted thereinto, it will be positioned to locate the patch
12 and particularly its magnetic stripe 14 in an engageable and
transducing relationship with the magnetic read/write head 20.
The passbook gripper mechanism comprises, in general, a U-shaped
member generally indicated at 28, including two generally parallel
arms 30--30 of similar construction connected at the closed end of
the U by cross member 32. The U-shaped member may be constructed of
a one piece member bent into the U-shaped form and disposed in the
mechanism so that its open end faces in the direction of the
entrance or mouth of the read/write station. The U-shaped member 28
forms the upper jaw of the gripper mechanism and is both pivotally
and translatably mounted on a rod 34 extending crosswise of the
member through aligned slanting slots 36--36 formed in the arms
30--30, the rod 34 being suitably mounted on supports at the outer
extremities thereof.
Cooperating with the outer ends of the arms 30--30 of the upper jaw
of the gripper mechanism formed by the U-shaped members 28 is a
lower jaw composed of two similar paddle-shaped elements 38--38.
These two elements lie under the extremities of the arms 30--30 and
are preferably beveled as at 40--40 to provide slanting faces up
which the leading edge 16 of a passbook is guided. Each
paddle-shaped element is provided with a rearward extension which
inwardly of its paddle end is L-shaped in cross section to provide
a vertical section 42 extending along side of its associated arm 30
and to which it is loosely pivotally connected by a stud 44. To
prevent the bottom jaw elements from rising vertically with the
upper jaw, each stud 44 extends through a vertical slot 46 as best
shown in FIGS. 7 and 8 so that the upper jaw may be rocked about
the pivot rod 34 without imparting vertical movement to the lower
jaw. However, such rocking movement of the upper jaw will impart a
horizontal retractible movement to the lower jaw as will be more
fully described hereinafter. Means in the form of a spring wire 48
is associated with each vertical section 42 of the lower jaw for
holding the same down against the base plate 22. The intermediate
portion of each spring wire is coiled several turns about the rod
34. One extremity of the wire 48 resiliently presses downwardly
against the horizontal paddle element 38 of the jaw with which it
is associated as indicated at 50 and its opposite extremity bears
against a lateral flange 52 on the adjacent arm of the upper jaw.
Each spring wire is of sufficient strength to hold the lower jaw
against upwardly movement during the rocking motion of the upper
jaw.
Carried on the outer extremity of each arm 30 of the upper jaw
component of the gripper assembly is a gripper in the form of a
shoe 54 of resilient material, such as rubber, which may be cast
thereon and provided with an integral portion thereof which enters
a hole through the end of the arm such as shown in dotted outline
56 in FIGS. 7 and 8 for interlocking engagement thereof. Each shoe
depends below the end of its arm 30 and will engage the leading
edge portion of the passbook following its insertion between the
upper and lower jaw members. The shoes 54--54 will be slightly
compressed as they engage the leading edge of the passbook and
their high frictional characteristic will aid in drawing the
leading edge of the passbook fully against the stop bar 26, as will
be more fully described hereinafter.
Superposing the gripper mechanism 28 of the read/write station is a
track member 58, a portion of which is shown in FIG. 1 and end
views are shown in FIGS. 7 and 8. The track member 58 extends
transversely over the arms 30--30 of the gripper mechanism and also
leftwardly thereof as viewed in FIG. 1, and may be supported as
shown by an interior frame member 59. A carriage whose supporting
plate is indicated at 60 is mounted for travel on the track member
58 and for this purpose it is provided with three triangularly
positioned rollers 62, two of which are shown on opposite sides of
the track member 58 in FIGS. 7 and 8. Preferably, the periphery of
the rollers are convexly rounded as shown and ride in concavely
shaped grooves 64 of the same radius of curvature formed in the
opposite parallel side edges of the track member 58. Each roller 62
is mounted upon the carriage plate 60 in any suitable manner such
as by the provision of a bolt 66 extending through the plate and
carrying a nut 68 on the upper surface of the plate.
Depending from the forward edge of the carriage plate 60 and in a
vertical plane approximately intersecting the shoes 54--54 of the
gripper mechanism is a plate 70 carrying on one side an upper
outwardly projecting pin 72 and on the other side a lower inwardly
projecting pin 74 as best shown in FIGS. 7, 8 and 10. The vertical
plate 70, together with its pins 72 and 74, will move with the
carriage in its to and fro motion on the track member 58. The
pin-carrying plate 70 is mounted for vertical movement relative to
the carriage plate 60 and this may be accomplished in any suitable
manner such as being hinged to the latter plate for rocking
movement about a horizontal pin indicated at 71. Also, carried by
the carriage is the magnetic transducing head 20 previously
referred to, and the latter also partakes of the same movement as
the carriage.
The transducing head 20 is mounted on the extremity of an elongated
flexible assembly generally indicated at 76 in FIGS. 9 and 10, the
opposite end of which is secured to the carriage for joint movement
therewith. The assembly 76 includes as part of its length a pair of
similarly formed parallel extending, flexible metallic blades or
flextures 78--which, as shown in FIG. 10, connect the head
extremity of the assembly to a block 80. The two parallel flexures
78--78 permit the head to be resistingly depressed downwardly to
engage the magnetic stripe 14 on the entering edge of a passbook or
the like, as previously explained.
For purpose of precisely positioning the gap of the transducing
head relative to the magnetic stripe and parallel to the magnetic
bits recorded thereon, the head 20 is adjustably connected to the
immediate adjacent block 82 at the outer end of the flexure members
by the provision of a metallic spring strap 84, best shown in FIG.
11, connected to the inner side of the head and block 82. On the
opposite or front side of these two members, there is provided an
adjustable provision for varying the angularity of transducing head
20 with respect to the adjacent block 82, which may take the form,
as illustrated in FIG. 11, of two complementary projections 86 and
88 on the head 20 and block 82 respectively, the latter projection
88 being provided with internal threads for receiving a screw 90.
In order to provide the fine adjustment of the angularity of the
transducing head with respect to its mounting on the carriage, the
connecting strap 84 should provide a slight clearance between the
head 20 and the adjacent block 82 as illustrated in FIG. 11. This
will enable the screw member 90 to finely adjust the head as the
screw is rotated in the threads of the projecting body 88 to vary,
if need be, the transverse direction of the gap 92 (FIG. 10) of the
head, relative to the magnetic stripe 14, and to bring the gap into
precise alignment with the data bits stored on the magnetic
stripe.
The left most portion of the head mounting assembly, illustrated in
FIGS. 9 and 10, is constituted by a block 94 which is secured by
the transverse pin 71 to a part of the carriage represented by the
plate 60. Normally, this connection holds the mounting assembly for
the transducing head 20 such that the latter will clear a passbook
of the usual size introduced into the read/write station.
In order to depress the head 20 into engagement with the magnetic
stripe on the passbook, the pair of pins 72 and 74 carried by the
lever 70 are utilized to force the head downwardly shortly after it
commences its movement along its path of travel. This depressing
action is performed, as best shown in FIGS. 7 and 8, by the
engagement of the lower inwardly projecting pin 74 with the
underside of a camming member 98 which forms the outer forward
extremity of a plate 100 secured to the underside of the interior
support 59 upon which the track member 58 is mounted. FIG. 7
illustrates the initial or starting position of the transducing
head prior to its engagement with the magnetic stripe of an
introduced passbook, and in this position it is evident that the
pin 74 is in engagement with the high side of the cam 98. Shortly
after the commencement of the travel of the head the pin 74 is
depressed by the cam 98 drawing down the arm 70 and its outwardly
projecting pin 72 to the position illustrated in FIG. 8 where the
head 20 has been lowered to engage the magnetic stripe on the
leading edge portion of a passbook introduced between the gripper
members. In this position it is evident that both the pins 72 and
74 have assumed a lower level position depressing the head 20
against the magnetic stripe.
Preferably, the outer projecting pin 72 acts upon the upper side of
a flexible blade member or finger 104 which is as viewed in FIG. 2
is secured by a lateral extension 105 (shown in FIG. 3) of the
carriage plate 60. The finger 104 overlies the transducer head
mounting assembly 76 for substantially the length thereof and has
its free end slightly dimpled for engagement with the head as
illustrated in FIG. 10. The outer projecting pin 72 of the camming
mechanism overlies an intermediate part of the finger 104 and when
its companion pin 74 is depressed by the camming surface 98 of
plate 100, it will in turn force the finger downwardly and flex the
pair of blades 78--78 also downwardly to lower the head into
engagement with the passbook. The two pins 72 and 74 together with
their supporting plate 70 move with the mounting assembly for the
head and with the finger 104 as is evident from a comparison of
FIGS. 2 and 3. The only member which remains stationary of this
operation assembly is the cam 98.
The gripper mechanism 28 is preferably operated by a solenoid 106
which, as shown in FIGS. 1, 2 and 3, is located along the rear side
of the read/write station and mounted so that its axis extends
parallel with the path of movement of the carriage 60. Forming part
of the solenoid is an armature 108 which, as shown in the
aforementioned Figure, is reduced in thickness to form a narrow
blade-like extension log which is enclosed within an inverted
U-shaped member 110 for the major portion of its length. At the end
remote from the solenoid the armature extension 109 is secured to
one extremity 112 of a coiled spring 114 carried by the support 22
of the apparatus and has its opposite extremity 116 fitted through
a rectangular opening in a projection 118 fixed to the cross member
32 of the upper U-shaped jaw member 28. In the position of the
parts shown in FIG. 7, where the jaws are separated and ready to
receive a passbook, the extremity 116 of the coil spring 114 is
disposed in the lower portion of the rectangular opening of the
extension 118. Upon energization of the solenoid, its armature 108
is retracted drawing the opposite end 112 of the spring 114
theretoward with the result that the spring is placed under tension
tending to raise the end 116 thereof as shown in FIG. 8. The
elevation of the end 116 of the spring will lift the rearward end
32 of the upper U-shaped jaw carrying member 28 first rocking the
front end of each side member 30 downwardly about the rod 34 until
the forward ends thereof carrying the shoes 54--54 abut the leading
edge of the passbook overlying the lower paddle-shaped jaws 38--38
with the result that the leading edge portion will be gripped by
the upper and lower sets of jaws As the end 116 of the coil spring
continues to rise, the slanted slots 36--36 in the arms 30--30
through which the rod 34 extends will cause the upper U-shaped jaw
member to bodily move rearwardly and at the same time jointly carry
the lower set of jaws therewith. Comparison of FIGS. 7 and 8 will
show the extreme positions of the upper and lower jaw members as
they move from a forward non-gripping position to a rearward
gripping position bringing the leading edge of the passbook into
abutment with the separated sections of the edge guide 26. It is
apparent that the simple straight-line movement of the armature 108
of the solenoid causes the upper set of jaws 54--54 to perform a
compound motion initially rocking into gripping relation with the
lower set of jaws 38--38 and then thereafter causing bodily
movement of both sets of jaws rearwardly to effect a reference
position for the leading edge 16 of the passbook against the edge
guide or bar 26.
Protruding slightly beyond the front face of the separate sections
of the stop bar 26 is a pair of spaced-apart control elements
identified at 120--120, one of which is located within the area
embraced by the U-shaped jaw member 28 as shown in FIG. 1 and the
other about the maximum distance of travel of the carriage 60 to
the left as viewed in FIGS. 1, 2 and 3. These control elements or
buttons are first engaged by the leading edge of the passbook and
are depressible into their respective units or boxes 122 as the
leading edge 16 approaches and abuts the stop bar 26. Each button
enters a control box 122 which preferably contains an electrical
switch which may be of the magnetic reed switch type. These two
switches are in circuit series relation and both must be closed
before a signal is generated which is employed for actuating the
solenoid 106. If the passbook should be in an askewed condition as
it enters the entryway of the apparatus, actuation of only one of
these two switch units 122 by its control button will fail to
produce the signal with the result that the solenoid will not be
operated to draw in the passbook. Such an indication of faulty
entry can be visually indicated by a signal lamp to notify the
operator.
The mounting of the carriage 60 for movement on the track 58 has
been previously described herein. The provision in the illustrated
embodiment of the invention for moving the carriage comprises a
cable system connected to the carriage intermediate its ends and at
one end to a resilient mechanism whose stored energy is used to
move the carriage in one direction and at the other end to a rotary
power source which is coupled to a rotary driving member of the
machine with which the read/write station is associated. Referring
to FIGS. 2, 4 and 5 and particularly to FIG. 4, the cable system is
constituted by a single cable 124 extending from the aforementioned
resilient member in the form of a coiled spring 126 to a rotary
power source enclosed within the block 128. Intermediate its ends
the cable is fixed to the plate 60 representing the carriage unit
of the mechanism. It will be noted that the cable system of FIG. 4
may be overlaid upon FIG. 2, but it is separately shown in FIG. 4
for purposes of clarity. In FIG. 4, the carriage 60 is shown in the
right hand position of its movement preparatory to moving the
transducing head to the left to perform a transducing operation on
the magnetic stripe 14 of a passbook. A clamp 130 carried by the
carriage plate 60 serves to secure an intermediate portion of the
cable to the carriage and specifically that section of the cable
identified at 132 and having a straight-line connection with the
spring 126. Separate sections of the cable are evident from FIG. 4
and in succession from section 132 constitute sections 134, 136,
138, 140, 142 and 144. At appropriate turning points in the system,
pulleys are provided for guiding the cable in its different
directions of movement, such pulleys being identified at 146.
The source of rotary power for moving the cable in one direction as
illustrated in FIG. 5 and comprises a drive shaft 148 coupled
through a one revolution clutch of conventional construction to a
continuously rotating power shaft 156 to which a fly wheel 149 is
connected. Carried by drive shaft 147 and jointly rotatable
therewith in the direction of the arrow is a generally elliptical
cam member 150. A cam follower 152 bears on the periphery of the
cam and is journaled in one arm 154 of a tripedal lever which is
pivotally mounted as at 156. The opposite arm 158 of the tripedal
lever carries a pulley 146 of the cable system and about which is
trained the juncture of the two cable sections 142 and 144 of the
system. The last cable section 144 is secured to a supporting
member by means of a clamp 160. It is evident from FIG. 5 that the
cam 150 will rock the tripedal lever back and forth as the follower
152 rides on the cam thereby moving the follower 152 and the pulley
146 back and forth between their respective full line to dotted
line postions as illustrated in FIG. 5. It is apparent that when
these elements move from their respective dotted line positions to
full line positions they will tension the cable to move the
carriage to the left as viewed in FIGS. 1, 2 and 4. However, upon
return movement from full to dotted position the coil spring 126
will tension the cable to move the carriage 60 toward the right as
viewed in these aforementioned Figures.
It is evident from the description hereinabove that the invention
provides automatic magnetic read/write capabilities for a bank
passbook and the like. A magnetic patch affixed to the outside
cover of a passbook 10 provides the area where the magnetic
information, such as account number, balance, and passbook line
number are recorded. The passbook is inserted into the machine to
its full extent and at this point actuates the two side-by-side
switches 122--122 which insure that the passbook is within a
specified distance of the limit stop 26 and within a specified
maximum skew relationship from the limit stop. Actuation of these
switches will trigger the solenoid which actuates the two jaw
components of the gripping mechanism. These jaws grip the passbook
and pull it firmly up to the limit stop and hold it there.
At this point the magnetic read/write head 20 can be actuated, and
motion for this is derived from the platen space drive of the
machine with which the read/write station is associated and through
the gearing, one-revolution clutch, fly wheel, cam and pulley and
cable means previously described. The read/write transducing head
transverses back and forth from right to left over the area of an
introduced passbook 10 on which the magnetic stripe bearing patch
is affixed. Both magnetic reading and writing occurs from right to
left as the operator faces the machine. No reading or writing
occurs on the return stroke of the read/write head, although the
head remains in contact with magnetic stripe 14. Information is
read from the stripe, compared with information in a central
processor of the machine, new information is entered from a
keyboard, computed and the magnetic stripe information is updated
by the head magnetically writing this information on the
stripe.
The passbook is then spaced up to correct print line automatically
read from the magnetic stripe in order to have the latest
transactions posted in book. A start read signal (photo transistor
and lamp) may be included in the design to indicate the proper time
to start reading after the transducing head 20 is up to a constant
speed. An over-fold control mechanism may be included in the
machine or data processing apparatus for preventing any printing in
the area adjacent to the fold of the passbook or other folded
documentary material.
While a particular embodiment of the invention has been shown and
described, it will be understood, of course, that it is not desired
that the invention be limited thereto since modifications may be
made, and it is therefore contemplated by the appending claims to
cover any such modifications as fall within the true spirit and
scope of the invention.
