Tape Cartridge For Machines

Abstract

An instant load cartridge for use in any machine utilizing tape, ribbon, film or other such web-like material transported from a supply spool to a take-up spool and passing over or over and under a plurality of spools, guides or the like already existing in the machine including a sealed casing having a supply spool with the web-like material thereon, guide means for the web-like material, and means to retain the web-like material adjacent to an existing take-up reel on the machine so that the web-like material may be quickly connected to the take-up reel by use of an existing retaining key whereby the cartridge may be instantly loaded into the machine thereby eliminating the necessity of manually threading the web-like material through the existing machine for reducing the time required to replenish the supply of the web-like material in the machine.

Description

The use of various types of web-like materials such as tape, ribbon, film and the like is quite prevalent in numerous machines with the tape, ribbon, film and the like normally being provided on a supply reel, spindle, spool, roller or the like and extending over, around or under guides in the form of reels, spindles, spools, rollers or the like and being ultimately wound upon a take-up reel, spindle, spool, roller or the like. When the supply of tape becomes exhausted, it is necessary for an operator to remove the tape from the take-up reel or in some instances to remove the entire take-up reel and tape wound thereon, replace the tape on the supply spool, or in some instances to replace the entire supply spool with tape thereon and thread the tape over, around or under the various guides incorporated into the machine and ultimately attach the free end of the tape to the take-up reel. This operation requires the expenditure of considerable time depending upon the manual dexterity of the person performing this operation and the particular orientation of the various components with which the tape must be associated.

One example of such a tape is in cash registers employed in various retail establishments. In supermarkets, grocery stores and other business establishments that have heavy customer traffic, there is usually provided a plurality of check-out counters each of which is equipped with a cash register. After the individual purchases of the customer has been rung up and totalled, the customer makes payment for his purchases and receives a receipt in the form of a segment of tape having the purchases itemized thereon and totalled. This tape is torn from a customer receipt tape which is printed by the cash register in a known manner. Also, at the same time, the cash register prints at least the same information on a detail tape which stays in the cash register. It is quite annoying to customers for the check-out counter operator to have to delay the check-out operation while the detail tape is being replaced inasmuch as this requires considerable time and in actual practice, the particular check-out counter is closed to customers when the detail tape is being replaced.

In one particular cash register presently available and employed in many stores, the detail tape must be threaded over, around and under six rollers from the supply spool and then connected to the take-up reel by the use of a retaining key.

It is an object of the present invention to provide a tape cartridge for instantly loading a detail tape into a cash register thus eliminating the necessity of the cash register operator to expend considerable time re-threading the detail tape through the guide rollers of the cash register with it only being necessary for the operator to remove the retaining key, remove the cartridge with the exhausted tape therein, insert a new cartridge, then insert the retaining key in place and rotate the retaining key approximately two turns in a clockwise direction to secure the detail tape to the detail tape take-up reel. This materially increases the efficiency of operation of the cash register and reduces inconvenience to the customers of a business establishment.

Another object of the present invention is to provide a tape cartridge constructed to enable employment with existing cash register structures without modification thereof.

A further object of the present invention is to provide a tape cartridge which includes a sealed housing to prevent the cash register operator from tampering with the tape, with the cartridge also including identifying indicia such as a code number or the like to enable foolproof security check on the operation of the cash register.

Yet another important object of the present invention is to provide a tape cartridge which is constructed of relatively inexpensive material and is quite simple in construction and operation and will increase efficiency of cash register operations which in turn will improve customer relations as well as improve the working conditions of the cash register operator.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIG. 8 is a detailed sectional view, on an enlarged scale, illustrating the tape passing over and under certain of the rollers or spindles on the cash register.

While the tape cartridge of the present invention is particularly adapted for use in a cash register and the invention has been disclosed specifically in conjunction with a cash register, it is pointed out that it is within the scope of this invention to utilize the concepts incorporated into the tape cartridge in conjunction with various other business machines employing a web-like tape or the like therein. Referring specifically to the drawings, FIG. 1 illustrates diagrammatically the structure which confronts a cash register operator when the door which covers the tape receiving area is opened. A supply roll of customer receipt tape 10 is provided and extends over guide rollers and extends forwardly through a slot in the cash register for enabling the cash register operator to grasp the free end thereof and tear it off and present it to the customer as a receipt. As illustrated, the customer receipt tape is laterally accessible and the supply thereof can be replenished by the cash register operator without any substantial difficulty. However, the conventional detail tape 12 is not discharged from the machine but is retained as a permanent record of the transactions of the cash register and is employed when the transactions are checked against the money in the cash register drawer. The arrangement of the detail tape varies but in one typical cash register, the detail tape 12 is provided on a roll which is mounted on a stud 14 and the tape is then pulled off the top of the roll forward over studs 16, 18, 20, 22, 24 and 26. The detail tape 12 is then brought under the take-up reel 28 and the retaining key 30 is then inserted to secure the detail tape 12 to the take-up reel 28. The retaining key 30 is then rotated approximately two turns to start the detail tape 12 on the take-up reel 28. The entire assembly is covered by a door 32 generally in the form of a cover plate which may be hingedly connected in any suitable manner with the door being retained in place by a lock structure 34 which prevents unauthorized personnel from normally gaining access to the detail tape. However it frequently occurs that unauthorized personnel have, through devious means, obtained keys to operate the lock 34.

To remove the used portion of the detail tape from the cash register, it is of course first necessary to unlock the lock 34 and open the door 32. There is always a small portion of the used detail tape that is not wound on the tape take-up reel 28. The detail tape must be manually torn between the used and the unused portion and the used portion must be wound, manually, onto the take-up reel 28. The used detail tape is then removed from the cash register. The take-up reel 28, being an integral part of the cash register, remains in the cash register. The unused detail tape, remaining in the cash register, is then reconnected to the detail tape take-up reel 28 as described in the preceding paragraph.

The tape cartridge of the present invention is illustrated in FIGS. 2, 3, 4, 5, 6, 7 and 8 and is generally designated by reference numeral 40 and includes a casing or housing 42 having an outer side wall 44, an inner side wall 46 and a peripheral wall 48 extending between the side walls 44 and 46. The housing 42 may be constructed of plastic material and is preferably of unitary one-piece construction. Disposed in one portion of the housing 42 is a supply of detail tape 50. The detail tape 50 is wound into a spiral roll having a hollow interior for receiving the supply spool spindle or stud 14 of the cash register which is also received through a suitable opening in the inner wall 46 of the housing 42. The detail tape 50 then extends over guide member 52 which extends between the walls 44 and 46 and orients the detail tape 50 so that it will pass appropriately over the stud or roller 16 on the cash register. Additional guide members 54, 56, 58 and 60 are provided interiorly of the housing 42 and each of these guides extend transversely between the inner surfaces of the walls 44 and 46 and are provided with rounded outer edges. The end of the tape 50 is attached to an anchor member 62 which is in the form of a slotted rod with the terminal end of the detail tape 50 extending through the slot 64 and being anchored therein such as by a frictional gripping action. The detail tape 50 is retained in a straight line condition so that it will be in engagement with and generally tangential to the take-up reel 28 so that one of the prongs 66 of the retaining key 30 will anchor the detail tape 50 to the take-up reel 28 by urging the detail tape 50 into one of the grooves 68 in the flat opposed side surfaces 70 of the take-up reel 28. The retaining key 30 is conventional in construction and includes a handle 72 and a plate 74 with two parallel prongs 66 affixed thereon. One of the prongs is shorter than the other but both of them extend over a major portion of the length of the take-up reel 28 and secure the detail tape 50 in position in the same manner as the conventional tape 12 is secured to the take-up reel. The take-up reel 28 and the retaining key 30 are presently employed in cash register structures. Before a new tape cartridge 40 is inserted into a cash register, the retaining key 30 is removed. This is followed by the removal of the old tape cartridge. When the new cartridge is inserted, it is only necessary to insert the retaining key 30 and turn it for approximately two revolutions which will disconnect the detail tape 50 from the anchor member 62 and start the detail tape 50 on the take-up reel 28.

The peripheral wall 48 of the housing 42 is provided with an appropriately located aperture 76 therein for enabling printing on the detail tape 50 by the pivoting marking assembly 78 which pivots about shaft or stud 80 in a direction towards the aperture 76. After operation, the marking assembly 78 returns to its original position. This position of "rest" being determined by the stop roller 82. The marking assembly 78, an existing part of the cash register, includes an inked ribbon which remains outside and tangent to the top of the tape cartridge 40. The inner wall 46 of the tape cartridge 40 having open areas for receiving the ribbon marking assembly 78.

FIG. 4 illustrates a typical construction of one of the studs or rollers provided on the cash register such as the roller or stud 26 which projects through an opening 84 in the inner wall 46 and which has a reduced axial outer end 86 that is normally received through the outer wall of the cash register structure which is in the form of a plate-like structure interiorly of the door 32 which interconnects the ends of the various rollers and studs. This plate-like structure is referenced as numeral 8 of FIG. 1. As disclosed earlier, this support plate 8 is removed and disposed of when the tape cartridge 40 of this invention is utilized. The outer wall 44 is provided with a cylindrical projection 88 which telescopically receives the shouldered end 86 of the roller 26 to provide stability and support for the roller 26 during the operation of the cash register. Also, the cylindrical projection 88 defines a guide for the detail tape 50 to retain the tape in position for positioning over the roller 26 when the tape cartridge 40 is inserted into the machine.

The top surface of the peripheral wall 48 is provided with a tear-off tab 90 which has an identification code or number 94 thereon. An identical identification code or number 96 is formed on the interior of the cartridge such as on the inner surface of the peripheral wall 48 adjacent to the roller or stud 26. This code number 96 identifies the cartridge and the user cannot determine the code inside of the cartridge without mutilating or destroying the cartridge. When the cartridges are given to a user, the tear-off tab 90 is removed to provide a record of those cartridges that were provided a particular user for subsequent check of receipts as explained in more detail hereinafter. Also space is provided on the upper surface of the cartridge wall 48 adjacent to the tear-off tab 90, as designated by the numeral 98, for providing an area on which indicia may be written such as sequence numbers for use in the security check as described in more detail hereinafter.

FIG. 8 illustrates a structure similar to that of FIG. 2 but in this arrangement the detail tape 50 extends under the roller 80 rather than over it and guide ribs 100 are provided on the inner surface of the peripheral wall 48 to guide the detail tape 50.

FIG. 8 illustrates one of many variations in the orientation of the detail tape, ribbon, film or other web-like material so that it may be employed with various cash registers, business machines and any other machines employing material of this type.

In some installations, it may be necessary to adapt existing machines in a limited manner but primarily, the tape cartridge is to be employed with existing machines such as cash registers without any modification or alteration thereof to the existing mechanical mechanism thus increasing the speed and convenience with which the machine can be loaded. In many instances this loading can be accomplished in a matter of seconds. Also, the tape cartridge provides additional security against pilferage to the owner of a business who employs the cartridge in a machine where money or securities or other items of cash value are placed or in which incoming monies are tabulated.

There has been a continuing problem of pilferage of monies or securities that have been "rung up" or processed in a cash register. Recognizing this problem, most manufacturers of cash registers incorporate an optional feature in their machines generally referred to as "accumulative total." This "accumulative total" feature supposedly provides a fool-proof method which enables the owner of the cash register to determine that monies that have been "rung up" or processed through the cash register have been reported. A new cash register having this feature will reflect an accumulative total of zero. All sales processed through this cash register continue to add to the accumulative total so that at any instance the total of the detail tapes submitted to the owner, plus the total on the detail tape at the time of a check of the cash register should be in accord with the amount reflected by the accumulative total reading of the cash register. However, this feature is not foolproof inasmuch as the cash register company builds into each of the cash registers the capability of resetting the accumulative total. While it is true that special tools are required for resetting the accumulative total, there is a distinct possibility that such special tools can and do get into the hands of persons that have no qualms about resetting an accumulative total. For example, if an owner of a store adds the total of the detail tapes from any cash register and checks the accumulative total reading on that cash register and they agree, then the owner would normally assume that no pilferage has occurred. However, someone employing special tools could easily reset the accumulative total of the cash register. While the cash register company assures that the special tools are available only to mechanics employed by the cash register company, from a practical standpoint, there is a distinct possibility that such tools can be obtained and the accumulative total reset thus rendering this security feature on existing cash registers unreliable.

In view of this problem, some cash register companies provide the accumulative total feature in a unit protected by a lead seal. The seal that is used is similar to the seal used on a postage meter or watthour meter. The seal must be broken in order to gain access to the mechanism of any of these devices. Here again, the special tools and seals required to reseal the accumulative total unit compartment are available, supposedly, only to certain cash register company employees. It is still possible for a dishonest cash register company employee to secure the necessary tools and seals and this employee would be able to reset the accumulative total and reseal the unit. So here again the accumulative total feature does not solve the problem of pilferage from cash registers. Of course, the cash register operator would have to provide a detail tape registering the lower total that would be reflected on the accumulative total which has been reset. This is a quite simple matter for the user of the cash register since he may employ a cash register exactly like those used in the store at some outside location and merely run a detail tape reflecting a lower total so that there would be the same total on the accumulative total and on the totals of the detail tapes from any given cash register. Whenever a cash register is checked, the accumulative total shown in the cash register should equal the total of all of the detail tapes processed through that cash register plus the total shown on the detail tape being employed at the time of checking.

Even an inventory check may not uncover pilferage. For example: The owner of a jewelry business will average two times mark-up on cost. That is to say, merchandise that cost $1.00 will be sold for $2.00. What will the shortage of $120,000.00, pilfered in cash by the jewelry store manager, reflect in inventory? By pilfering $120,000.00 in cash from the business the jewelry store manager has actually pilfered $60,000.00 in inventory and he has actually pilfered $60,000.00 in profits! A physical inventory can only reflect the inventory shortage of $60,000.00. It cannot reflect the $60,000.00 in profits pilfered by the jewelry store manager. But a physical inventory will not necessarily reflect any shortage and/or pilferage! Why is this? The jewelry store manager is smart and knows that an inventory check could reveal an inventory shortage of $60,000.00 and consequently result in an investigation of his operation. To avoid this the jewelry store manager has taken $60,000.00 cash of the pilfered $120,000.00 cash and has replaced the missing inventory. Now, a physical inventory will not reveal an inventory shortage. The detail tape totals check with the accumulative totals of each of the cash registers employed in the jewelry store. The owner of the jewelry store is satisfied that no shortage, either inventory or cash, exists. The jewelry store manager has just pilfered the jewelry store owner of $60,000.00!

In addition to offering a convenience feature and reducing the time necessary to reload the cash registers, the tape cartridge of this invention introduces an additional security feature. For example, when the tape cartridge 40 is delivered to a store such as a branch store of a chain of stores, the identification code 94 on the tear-off tab 90 identifies this cartridge. Since the tear-off tab 90 is removed before the cartridge is delivered to the store, there is no method, short of destroying the cartridge by which the user can determine the identification code 96 inside the cartridge. Thus, the owner of the business would make a record by copying down the identification code 94 and then removing the tab 90 before the cartridge is delivered to the store. Thus, the owner of the business would have a record of all detail tape cartridges sent to a particular store. Thus, when the detail tapes which are returned to the owner from the store are received and opened, the owner of the store can be certain that the detail tapes were detail tapes actually processed in one of his cash registers; as will be shown later; during the course of a business day and is not a detail tape omitting or altering sales as was the case in the previous discussion of the accumulative total feature type cash registers. The owner of the store will know this because the detail tape has a customer sequence number printed on it and when checking the detail tape, it is quite easy to determine that all customer sales or numbers are sequential. In other words, if a customer number and sale was rung up when the cartridge was removed from the cash register, the customer number for that particular sale would not appear on the detail tape in the cartridge which would readily be detected by the owner of the store. However, the cartridge of the present invention is constructed so it is virtually impossible to remove it and then reinstall it notwithstanding, even if the cartridge was reinstalled, there would be a break or hiatus in the customer sequence number unless someone knowledgeable having the proper tools immediately reset the cash register to produce the correct customer number prior to processing the next sale. In this event, the removal and reinstallation of the cartridge would be detected by a spring-loaded device 102 which applies tension on the detail tape 50 as it accumulates on the take-up reel 28. A marking pen could be provided on the tension member 102 to imprint a continuous line spaced inwardly from the edge of the detail tape 50 and would provide evidence as to how many times the sealed cartridge 40 has been removed from and installed in the cash register.

In an effort to pilfer by providing a bogus detail tape in an authorized tape cartridge, the user of the cash register would obtain an additional cash register of exactly the same type as those being used in the store. He would place an unauthorized detail tape in the cash register in the store and place the authorized tape cartridge in the unauthorized cash register. The unauthorized cash register would have its customer number set to correspond with the customer number of the authorized cash register being employed in the store. At the end of the business day the operator of the cash register would have to reset the accumulative total of the authorized cash register in the store to reflect the lower total that would appear on the authorized tape cartridge in the unauthorized cash register. However, such procedures would not be successful without being detected inasmuch as the owner of the business would instruct the operator of the store which sequence of cartridge to use as determined by the sequence numbers 98. Then, without notice and without any schedule known to the store operator, a security service employed by the business owner will visit the store, produce proper identification and remove the sealed tape cartridges then in use in the authorized cash registers and exchange them for additional tape cartridges which have been brought by the security service and whose identification codes have been recorded by the store owner. Thus, under the circumstances, the authorized cash register in the store from which money was being pilfered would not contain the correctly numbered sealed tape cartridge 40 and, in fact, would not contain any of the tape cartridges sent to the store by the business owner thus preventing this manner of undetected pilfering.

In large establishments such as supermarkets or the like there may be more than twenty or thirty cash registers. An additional cash register can be brought in by the manager and used and not be detected by the store owners since there is no check on the detail tapes. That is to say, the store manager does not have to produce a detail tape from this additional unauthorized cash register; which he is using for pilfering; because the owners are unaware that this register exists!

The tape cartridge of this invention with the code number and sequence number thereon will clearly preclude the introduction of an additional cash register into a store having a multiple of cash registers for this reason: Let us assume a supermarket opens for business using thirty cash registers. Detail tapes bearing the sequence numbers 1 through 30 are the first tapes to be utilized. The security service, employed by the supermarket owner, visits the supermarket on the first day of operation and removes the detail tapes then in use which would be detail tapes with the sequence numbers 1 through 30. The security service asks the manager to install new detail tapes in all thirty cash registers. These detail tapes would bear the sequence numbers 31 through 60. If an unauthorized cash register is being employed by the store manager, one of these tapes (a tape bearing the sequence number of 31 through 60) is being utilized in the unauthorized cash register and the supermarket manager cannot produce that detail tape unused to the security service and his pilfering is immediately detected.

The identification code may be composed of letters, numbers or any combination thereof and may additionally employ a fingerprint which will provide an even better security check since this absolutely precludes reproduction of the tape cartridge, including the identification code 96 therein, itself. In any event, the identification code 96 is molded as part of the cartridge and because of this there is no possible way to remove the identification code from one cartridge and place it in another cartridge. The location of the identification code 96 is, as shown in FIG. 2, completely concealed. The identification code 96 is in a cavity enclosed by tape cartridge sides 44 and 46, tape cartridge peripheral wall 48 and tape cartridge guide members 58 and 60. There is no possible way, short of destroying the tape cartridge 40, to learn the identification code 96.

Any suitable indicating means may be provided on the detail tape to indicate that the end of the tape is being approached. This indication would be visible through a window 104 in the tape cartridge 40. The detail tape 50 becomes visible to the cash register operator as it passes by window 104.

Other features that could be incorporated into a cash register and associated with a cartridge of this type include:

A print-out clock which would record the time a sale was processed through a cash register.

A locking device that would prevent removal of the detail tape cartridge 40 from the cash register when the electrical power has been disconnected from the cash register. This locking device, or solenoid, would prevent a person from disconnecting the cash register from a source of electrical power in an effort to remove the detail tape cartridge 40 and defeat the continuous marking device discussed in other portions of this disclosure.

A continuous marking device affixed to tension member 102 (as described earlier in this disclosure) which would leave a tell-tale mark on the detail tape 50 indicating how many times the detail tape cartridge 40 had been removed from the cash register.

In addition to the features just described, the structure of the detail tape cartridge 40 itself is such that removal and reinstallation of the detail tape cartridge 40 is almost impossible! The aperture in the inner wall of the detail tape cartridge 40 closely receives the take-up reel 28 when the detail tape cartridge 40 is installed in the cash register. Any convolutions of the detail tape 50 on the take-up reel 28 would preclude removal of the detail tape cartridge 40 without also removing the detail tape 50 from the take-up reel 28. This is true because the combined diameters of the take-up reel 28 plus the detail tape 50 now exceed the diameter, which initially only accepted the take-up reel 28, in the inner wall of the detail tape cartridge 40. Once the detail tape cartridge 40, and the detail tape 50 therein, have been removed from the take-up reel 28, it is virtually impossible to reinstall the detail tape cartridge 40 and the detail tape 50 in such a manner as to associate the detail tape 50 with the take-up reel 28.

While the cash register has been used as being illustrative of a machine in which the advantages of the present invention are effective, the concept of this invention may also be incorporated into any machine utilizing tape, ribbon, film or other material that is moved from a supply reel in a linear manner onto a take-up reel over or over and under various guide structures such as reels, spindles, spools, rollers or other structures. These structures are used to facilitate the loading of the tape, ribbon, film or other material and to provide a security for the material in the cartridge.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
