Description
BACKGROUND OF THE INVENTION
This invention relates to the field of motion picture projector
units, and more particularly, to a projector-player unit having an
automatic film cartridge selection and changing mechanism.
DESCRIPTION OF THE PRIOR ART
Projector-players capable of receiving a plurality of sound film
cartridges and mechanisms for successively injecting and ejecting
the cartridges have been described in my co-pending applications
for U.S. Patent Ser. No. 171,130, filed Aug. 12, 1971, and Ser. No.
183,957 for a Unitary Projector-Player, filed on or about Sept. 27,
1971 now U.S. Pat. No. 3,771,859. In these devices, the separate
cartridges were loaded by hand into the injector mechanism, or into
a drum for feeding the cartridges into the projector.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a novel
cartridge loading mechanism for a projector-player comprising a
cartridge magazine, generally in the form of an elongate
rectangular block and formed with a plurality of cartridge
retention slots, that is loaded with cartridges and inserted as a
unit into the cartridge selector mechanism. The cartridge magazine
provides a convenient device for programming the order of play of
the cartridges as well as storage rack for the cartridges when not
in use.
It is a more particular object to provide a vertically movable
slide mechanism for moving the cartridge magazine as a unit into
any one of a plurality of selective positions.
It is an additional object to provide a horizontally movable slide
mechanism for injecting the selected cartridge into the projector
from its position in the magazine.
It is still another object to provide a horizontally movable slide
mechanism for ejecting the cartridge after completion of play and
returning it to its slot in the magazine.
With appropriate electrical controls, the mechanism can be operated
to select an individual cartridge, play all of the cartridges in
succession and then stop, or play all of the cartridges in
succession and then recycle to play them all again.

DESCRIPTION OF THE PREFERRED EMBODIMENT
The unitary projector-player of the present invention is designated
generally by the numeral 10 and comprises: a housing 11, a
projector 12, a screen 13, a speaker 14, a cartridge magazine 15, a
cartridge selector mechanism 16, a cartridge injector mechanism 17,
and a cartridge ejector mechanism 18. A hinged lid 19 is provided
on the top of the housing 11 for easy access in loading and
unloading the projector-player 10 with a plurality of sound-film
cartridges 20.
The screen 13 is of the rear-projection type and is mounted in the
front wall of the housing 11. The projector 12 is mounted on a
suitable stand 21 within the housing 11 and projects the pictures
from the film within a film cartridge 20 onto the screen 13. The
sound from the film within a cartridge 20 is also picked up by the
projector 12 and broadcast through the speaker 14.
In an alternate means of projection in which the projected image is
reversed the image is initially projected onto a mirror from which
it is reflected onto the screen. In one such construction the
screen may be placed in a sidewall of the housing (in the sidewall,
e.g., on which speaker 14 is now shown as being located in FIG. 2)
with a mirror located between the projector lens and screen.
The cartridge magazine 15 comprises a generally rectangular body 25
formed with a plurality of transverse slots 26 which receive in a
close sliding fit relationship the film cartridges 20. The body 25
is also formed with a plurality of clearance slots 27 located
between and below the slots 26. The magazine 15 is also provided
with a carrying handle 28 attached to the top of the body 25.
Two pair of front and rear guide rails 29 and 30 are vertically
mounted within the housing 11 adjacent to the projector 12 and
retain the cartridge magazine 15. The magazine 15 is adapted to be
moved selectively up and down within the guide rails 29 and 30 by
the selector mechanism 16. The rails 29 are formed with slots or
openings 31 on the side adjacent to the projector 12 to allow the
transfer of the cartridges 20 therethrough from the magazine 15 to
and from the projector 12.
The selector mechanism 16 comprises a vertically mounted slide
block 35 formed with an internal well 36, a slide 37, a drive motor
38 attached to the slide 37, and a magazine support bracket 39 also
attached to the slide 37. The bracket 39 has an upright member 40
disposed between the rear guide rails 30, and an integral
transverse base member 41. The member 40 carries an upright pin 42
which engages a hole 43 formed in a flange 44 integral with the top
of the magazine body 25. The base member 41 carries two upwardly
extending pins 45 which engage holes 46 formed in the bottom of the
magazine body 25. The slide 37 is constrained to move vertically up
and down by a pair of guide rails 47 attached to the slide block
35. The motor 38 has a drive shaft 49 which extends horizontally
through a vertical slot 50 formed in the side of the block 35. The
shaft 49 carries a pinion gear 51 which engages a vertically
mounted rack 52 on the side of block 35.
Each of the film cartridges 20 has a molded plastic outer shell
formed with a pair of opposed horizontally extending arms 22. The
arms 22 facilitate injection into and ejection from the projector
12 as will be described hereinafter.
The cartridge injector mechanism 17 comprises a horizontally
mounted base block 55 formed with an internal well 56, a horizontal
slide 57, a drive motor 58 attached to the slide 57, and a pair of
vertically mounted injector pins 59 carried by the slide 57. The
slide 57 is of an enlarged U-shaped configuration which surrounds
the cartridge selector mechanism 16. Each of the arms of the slide
57 carries one of the pins 59 which are adapted to engage
indentations 60 formed in the arms 22 of the cartridges 20. The
slide 57 is constrained to move in one dimension in a horizontal
plane by a pair of guide rails 61 mounted on upright supports 62
parallel to guide block 55. The motor 58 has a drive shaft 63 which
extends through a horizontal slot 64 formed in a side of the block
55. The shaft 63 carries a pinion gear 65 which engages a
horizontal rack 66 mounted on the side of the block 55.
The cartridge ejector mechanism 18 comprises a horizontally mounted
base block 75 formed with an internal well 76, a horizontal slide
77, a drive motor 78, and a pair of vertically mounted ejector pins
79 carried by a pair of upright posts 81 attached to the slide 77.
The drive motor 78 has a shaft 82 which extends through a
horizontal slot 83 formed in the side of the base block 75 and
carries a pinion gear 84. The pinion gear 84 engages a horizontal
rack 85 mounted on the side of the block 75. The slide 77 is
constrained to slide in a horizontal reciprocal motion by a pair of
guide rails 86 mounted on upright pillars 87.
Referring now to FIG. 4, the control panel for the projector-player
10 is illustrated. The control switches are seen to comprise: an
on-off switch 90, a volume control 91, a sequence control switch 92
which plays all of the cartridges 21 in succession, then stops, a
second sequence control switch 93 which plays all of the cartridges
20 in succession, then recycles, a select play switch 94 for
allowing individual selection or continuous play, and a plurality
of individual selector switches 95 for selecting a particular
cartridge 20.
In operation, the projector-player 10 functions as follows: The lid
19 is raised and a full cartridge magazine 15 is inserted into the
guide rails 29 and 30. The instrument is turned on by switch 90 and
the select play switch 94 is set for either continuous play or
individual selection. Assume that continuous play is selected and
that either switch 92 or 93 is activated. The drive motor 38 of the
selector mechanism 16 is energized and the cartridge support
bracket 39 is moved downward until the first cartridge 20 is
aligned with the openings 31. The motor 58 of the injector
mechanism 17 is then energized causing the slide 57 to move to the
left (as shown in FIG. 1) pushing the cartridge 20 through the
openings 31 into the projector 12. The projector 12 picks up the
film within the cartridge 20 and displays the pictures on the
screen 13. After the cartridge 20 is injected, the motor 58 is
energized in the opposite direction and the slide 57 is returned to
its original position.
Upon completion of the play of the particular film, the motor 78 of
the ejector mechanism 18 is energized causing the slide 77 to move
to the right (as shown in FIG. 1) and ejecting the cartridge 20
from the projector 12 and returning it to its slot 26 in the
magazine 15. During the ejection cycle, the pins 79 bear against
the arms 22 and the support bar 80 extends into the slot 27 in the
magazine body 25 immediately below the particular cartridge slot 26
to which a cartridge 20 is being returned. After the cartridge 20
has been returned to its slot 26, the motor 78 is energized in the
opposite direction and the slide 77 returned to its original
position.
The motor 38 of the selector mechanism 16 is again energized,
lowering the magazine 15 until the next cartridge 20 is aligned
with the openings 31. The motor 58 of the injector mechanism 17 is
again energized and the second cartridge 20 is injected into the
projector 12. After the cartridge 20 is injected, the motor 58 is
energized in the opposite direction and the slide 57 is returned to
its original position.
The operational cycles described are repeated until all of the
cartridges 20 have been played. If the switch 93 had been activated
originally, the selector mechanism 16 is activated to raise the
cartridge magazine 15 to its uppermost position and the complete
cycle repeated.
A modified form of the invention is illustrated in FIGS. 8 and 9.
In this modification the injector and ejector mechanisms are
incorporated into one unit 218. The unit 218 is similar to the
ejector mechanism 18 but differs in that the support bar carries
both ejector and injector pins. The cartridge magazine 15 and
selector mechanism 16 are of the same type as in the unit shown in
FIGS. 1 and 2.
The injector-ejector mechanism 218 just like the ejector mechanism
18 comprises a horizontally mounted base block 275 formed with an
internal well 276, a horizontal slide 277, a drive motor 278, and a
pair of horizontally extending support bars 280 carried by a pair
of upright posts 281. The drive motor 278 has a shaft 282 which
extends through a horizontal slot 283 formed in the side of the
base block 275 and carries a pinion gear 284. The pinion gear 284
engages a horizontal rack 285 mounted on the side of the block 275.
The slide 277 is constrained to slide in a horizontally reciprocal
motion by a pair of guide rails 286 mounted on upright pillars
287.
The support bars 280 are of substantially U-shaped construction
each having a pair of inwardly extending arms 291 and 292. The
support bars 280 carry a pair of horizontally spaced injector pins
293 and a second pair of horizontally spaced ejector pins 294, the
latter being spaced from the injector pins 293 along a line
parallel to the direction of travel of the horizontal slide
277.
The injector pins 293 are positioned on the innermost ends of the
arms 291 while the ejector pins 294 are positioned on the innermost
ends of the arms 292 to contact opposite sides of the arms 22
formed on the cartridge shell.
In operation, after the drive motor 38 of the selector mechanism 16
has been energized and a cartridge 20 is aligned with an opening
31, the motor 278 is energized causing the slide 277 to move from
its "rest position" to the left. By this movement, the outer
injector pins 293 on bar 280 contact the arms 22 pushing the
cartridge 20 through openings 31 into the projector 12. The
projector 12 picks up the film within the cartridge 20 and displays
the pictures on the screen 13. At the end of the film run, the
motor 278 is energized in the opposite direction and moves the
slide to a "load position" which is slightly beyond the "rest
position." During this movement the inner ejector pins 294 bear
against the opposite surfaces of the film cartridge arms 22 to push
the cartridge back into its slot in the cartridge magazine. After
"load position" is attained the motor 278 reverses and moves back
slightly to the left to its "rest position" and stops. The movement
of the motor and the associated slide mechanism carrying the
injector and ejector pins is controlled by limit switches and other
necessary controls (not shown). It will be appreciated that the
drive motor 278 of the injection and ejection mechanism may be
mounted stationary with the rack attached to the slide 277 so that
the rack will move with the slide. This particular construction
shown in FIGS. 8 and 9 has the advantage of eliminating one slide
mechanism from the unit as a whole and is effective to reduce the
overall size of the unit.
There has been shown and described a unique mechanism for playing
selectively or in sequence a plurality of sound film cartridges in
a convenient, readily accessible manner. The film cartridges may be
stored in the cartridge magazines, and a plurality of such
magazines employed, or the cartridges may be replaced in a
particular magazine as desired.
It is to be understood that the embodiments shown and described are
by way of example only, and the invention is not to be considered
as limited thereto except insofar as the claims may be so
limited.
