CREDIT STORAGE MEMORY DEVICE FOR JUKEBOXES, GAMING DEVICES AND THE LIKE CROSS REFERENCE TO COPENDING APPLICATION This application is a continuation-in-part application of my copending earlier application coins No. 313,516

filed Dec. 8, 1972 now abandoned.

BACKGROUND OF THE INVENTION This invention relates to credit storage means, and is particularly directed to the provision of a credit storage device for controlling the operation of coin operated devices such as jukeboxes, as well as gaming devices and the like.

In the past, the registering of amount of money inserted in machines such as jukeboxes in order to ascertain the credits of an operator, has been accomplished generally by mechanical or electromechanical means. In such devices it is frequently desirable to provide means for ascertaining or granting a credit or bonus to the operator. For example, in jukeboxes, it is frequently desirable that the operator be given a credit for the insertion of a larger number of coins than the minimum number. In devices employed in the past, the ascertaining or granting of such credits or bonuses generally employ the same mechanical or electromechanical elements which were used in the summing operation in the device. Irrespective of the type of system employed, the granting or crediting of a bonus in such systems depends upon the input ofa single coin having a predetermined value, for example, upon the insertion ofa quarter or half-dollar coin into the device. For example, in such devices ifa unit price were cents, a bonus price may be three for 25 cents if a 25 cent piece were inserted in the device, and no other form of credit could be obtained, for example, by the insertion of smaller coin equivalent of a quarter.

U. 5. Pat. No. 3,548,387, discloses an apparatus in which a credit or bonus may be ascertained which is not a function of the value of individual coins. In this system, the credit or bonus may be a function of the total value of credit which has been accumulated in the device in any random fashion. In this system the accumulated credit is increased in accordance with the input of further amounts of money into the machine, such as a vending machine. Consequently, a customer who decides to insert a larger amoun tof money into the device at one time is given a discount, even though the money is in the form ofa number of separate coins. According to this patent, this result is accomplished by increasing the total credit in the device over and above the amount corresponding to the amount of money inserted in the machine. In this system, an electrical circuit is provided which counts the individual value units, and stores the sum of the counted input value units. Whenever the sum thus stored reaches a predetermined value, the circuit produces a bonus signal, and the bonus circuit is thereupon automatically returned to its initial condition. The counting and storage functions of the bonus circuit occur in parallel, and act simultaneously with the summing device itselfin the coin operated apparatus. The bonus signal is then supplied to an additional bonus circuit, which produces a second bonus signal if a predetermined second value of credit has been reached in the storage circuit. Thereupon, the

bonus circuit is returned to its initial position, corresponding to the initiation of a vending sequence, or by the initiation of summing of available credit that occurs upon the insertion of additional money in the apparatus.

The arrangement of this patent only permits the generation of a bonus signal in response to the accumulation of a defined non-adjustable total credit or coin value in the memory. This result is disadvantageous, since changing of the predetermined values for affording a discount necessitates complicated changes in the circuitry of the system. In addition, it is not possible in this type of circuit to provide a discount, as distinguished from a credit, in a form such that upon insertion of a larger amount of money into the vending machine the price of the goods is correspondingly reduced. In other words, the apparatus of the above patent cannot reduce the amount of credit required to buy a particular item from a coin operated vending machine.

OBJECTS OF THE INVENTION In view of the above, it is the aim of the present invention to achieve the following objects singly or in combination:

to provide a credit storage memory which is capable of providing either a bonus or of giving a discount as a function of the total amount of money inserted inthe apparatus;

to provide a credit storage memory device for a coin operated apparatus, which is capable of providing a bonus for a discount in response to the insertion of any individual coins, or any individual amount of money;

to provide a credit storage memory which is flexible in its structural features, so that by means of simple modifications, the machine can be employed with any type of money, for example with coins of the United States, as well as with foreign coins;

to provide a credit storage memory of the above described type, which is useful for a number of different discount ranges;

to provide a matrix circuit arrangement capable of receiving at its input the credit value of inserted coins and providing at its output a correlated number of different outputs, for example a number of games or records which may be played, which may represent the credit granted; and

to revalue and coin value and/or accumulative money value into a correlated credit value.

SUMMARY OF THE INVENTION According to the invention, the above objects have been achieved by providing a coin value input means having a plurality of inputs which are correlated to each other in steps and in accordance with a given relationship. The coin value input means are coupled to encoding means, which provide a binary signal corresponding to the value of coins inserted in the apparatus. Means are provided for inserting the encoded binary signals in an intermediate coin value storage shift register, and a full adder is provided for adding the contents of the intermediate storage register to a coin value storage shift register for storage therein of binary data corresponding to the value of coins inserted in the device.

A decoder circuit is connected to the coin value storage register for providing a signal related to the monetary sstem of the inserted coins, with the output of the decoder being applied to an interrogation device-and sequencing switch for sequentially applying outputs corresponding to the highest values stored in the coin value storage register to a conversion device. The conversion device, which may be a diode matrix, converts the signals received thereby to binary signals corresponding to units of operation of the apparatus involved. For example, in a jukebox, these units may be in the form of units corresponding to records which may be played. These signals are applied by way of an intermediate register to a play" shift register, also by way of a full adder. The outputs of the play shift register are decoded, and means are provided for indicating the availability of adequate credit in the play shift register for performing'the desired operations in the coin operated apparatus.

The transferof the contents of the coin value storage unit may be effected in one mode of operation in re-' sponse to the insertion of coins in the device, and in another mode of operation by the control of the operator in the utilization of the coin operated apparatus. The transfer is effected by'subtraction of units corresponding to the highest value signals detected by the interrogation device from the coin value storage register. For this purpose, the subtraction is accomplished in the corresponding full adder. In a similar manner, units are subtracted from the play shift register in response to operation of the device, by means of a subtraction input to the full adder .corresponding to the play shift register.

The arrangement of the presentinvention may also include means for adapting the operation of the coin operated apparatus to a number of difierent value units, so that different valued outputs may be available to the operator.

The entire circuitarrangement according to the pres ent inventio'n'may be embodied in the form of integrated circuitry, preferably by MOS techniques so that a very compact structure may be obtained for the device.

The arrangement according to the invention provides the particular advantage that the credit storage memory is very variable in its discount stages, and the individual discount stages may be correlated as desired to any given type of coin, and/or to any given desired accumulated credit. In addition, the arrangement provides the advantage that the coin or credit values are converted automatically into game or credit units, so that the conversion device may be readily programmed in any desired manner. For example, in one type of operation, a half dollar may be converted into three game units and a dollar may be converted into seven game units, thereby providing the operator extra credit for the insertion of a whole dollar coin in the device.

BRIEF FIGURE DESCRIPTION In order that the invention may be clearly understood, it will now be described, by way of example, with reference to the accompanying drawings, wherein:

FIG. 1 is a block circuit diagram of a coin value credit system according to the invention adapted for use in a jukebox;

FIG.- 2 is a block diagram of a timing circuit for use in the arrangement of FIG. l;

FIG. 3 is a block-diagram of a strobe generator which may be employed in the circuit of FIG. 1;

DETAILED DESCRIPTION ()FEXAMPLE EMBODIMENTS:

Referring now to the drawings, and more in particular to FIG. 1, therein is illustrated a block diagram of a coin value credit system for a jukebox comprising the credit storage memory according to the invention. A plurality of coin operated switches Cl C7 are provided with their normally closed circuit in series be tween a voltage source 10 and a coin strobe generator circuit 11. The normally open contacts of the switches are connected as inputs to separate AND-gates 12, the

other inputs of these AND-gates beingconnected to a lead 13. The outputsof the AND-gates 12 are connected by way of separate OR-gates 14 to an encoder 15. The switches C1 C7 are coin operated switches, and correspond to different valued coins which may be inserted in a jukebox. The number of switches is of course variable dependent upon the currency employed in the of installation. ofinstallation. When a coin of a given value is inserted in its respective slot in the jukebox, the corresponding switch C momentariiy changes its contacts, so that a pulse is applied to the .encoder circuit 15 by way of the corresponding AND- gate 12 and OR-gate 14. The functions of these gates will be discussed in further detail in the following paragraphs. Consequently, the insertion of coins in the jukebox effects the production in the encoder circuit 15 of a binary parallel code corresponding to the value of the inserted coins.

The binary coded outputs of the encoder 15 are applied in parallel to the separate stages 16 of a coin value intermediate storage circuit 17, also referred to as third register, by way of separate AND-gates 18. The other inputs of the AND-gates 18 are connected in common to the C and S" strobe output of the coin strobe generator circuit 11. In addition, each of the lines between an AND-circuit 12 and OR-circuit 14 is connected to a separate input of an OR-circuit 19 by way of a separate pulse shaping circuit 20. As will be described in greater detail in thefollowing paragraph, in one of the functions of the coin strobe generator circuit 1 1, a strobe pulse is produced on the output C and S" strobe line 21 in response to an output of the OR- circuit 19 so that, in the simplest form of operation of the circuit of FIG. I it may be said that the insertion of a coin in the jukebox enables the AND-gates 18 to permit the passage of the binary coded output of the encoder 15 to the third or coin value intermediate storage shift register 17. The passage of the signal to the third register 17 is of course timed with respect to the operation of the remainder of the circuit, as will be apparent in the following paragraphs.

As shown in FIG. 2, the arrangement of the present invention is provided with a clock pulse generator 25 of conventional nature having a clock pulse output (I) which is connected to each of the inputs denoted (b in the circuit diagrams herein. The clock pulses d) are also applied to a divider circuit 26, such as a ring counter, for producing a signal 1' synchronized with the clock pulses. in the illustrated embodiment of the invention the pulse repetition rate of the clock pulses is eight times the pulse repetition rate of the pulses 1' although it will be apparent that this ratio is dependent upon the particular design and application of the system according to the invention. The clock pulse generator 25 may provide clock pulses of opposite phase for use in the circuit, although for the sake of simplicity in the description of the invention only a single clock pulse train has been assumed.

Referring again to FIG. 1, the clock pulses (75 are applied to the stages 16 of of the third register 17 to effect the shift of the binary data therein to one input ofa serial full adder 28. The stage 16 of the register 17 remote from the full adder is connected to logic to effeet the resetting of the register after the data has been read out therefrom. v

The output of the adder 28 is connected to a coin terminal 29 for use in a further circuit of a system in accordance with the invention, and is also applied to the input stage 30 of a coin value storage register 31, also referred to as the first register. The output stage 32 is connected to the second input of the full adder 28, and the data in the first storage shift register 31 is shifted at the clock pulse rate. As a consequence, it is apparent that any data stored in the third or intermediate storage register 17 is continually added to data stored in the storage register 31, so that the data stored in the storage register 31 corresponds to the coin values of coins inserted in the jukebox, less any values that have been subtracted therefrom by means which will be disclosed in greater detail in the following paragraphs. The carry circuits of the full adder 28 are synchronized by the 'r signal, as illustrated in the drawings. 9

The separate stages of the first storage register 31 are connected in parallel to a decoder 35 for producing a parallel coded signal corresponding to the monetary system employed. The output of the decoder 35 is applied in parallel to a sequencing switch 36 by way of gate 37 operated by the 1' pulses. The sequencing switch 36 has a plurality of outputs S1, S2, S3, S5, S10, S20 and S50 corresponding to selected multiples of a basic coin unit of the monetary system for which the jukebox is adapted. The sequencing switch 36 includes means for sequentially selecting the highest value output of the decoder for transfer to a conversion device 38.

As an example, assume that the output S1 corresponds to cents, the output S3 corresponds to cents, and the output S corresponds to 60 cents. Further assume that the costs for playing a single record in the jukebox is 15 cents and that 80 cents has been inserted in the machine. By virtue of the decoding circuit 35, there will be an output thereof corresponding to the line S20 as well as outputs corresponding to the lines 53 and S1 denoting storage of 15 cents and 5 cents respectively. The sequencing switch 36 which may be an electronic sequencing switch, scans the outputs from the decoder from the highest value downward, and thus first detects the signal corresponding to 60 cents, and applies the signal to the conversion device 38. Subsequently, the value corresponding to 15 cents is detected and applied by way of line S3 to the conversion device 38. The signal corresponding to 5 cents is then detected, but since this value is lower than the amount required to play a record, and hence does not correspond to a multiple of plays, a signal in response to detection of a value of 5 cents is applied by way of AND- gate 39 to an indicator 40. The indicator 40 thus indicates that there is a credit in the jukebox for coins which are not sufficient, however, to enable the playing of a record.

The conversion device 38 is employed for the purpose of converting the'signals applied thereto from the sequencing switch to parallel signals P1, P2, P4, P8 and P16 corresponding to the number of play units of records to which the operator is entitled. The conversion device may be, for example, a diode matrix and is preferably readily replaceable in the unit to enable the rapid and easy conversion of the control system to any desired correspondence between coin values and play units. For example, the conversion device may be programmed so that the greater the amount of money put in at a given time, the proportionately greater number of records that may be played, i.e., to give a discount or a credit depending upon the value of coins inserted. For example, if 15 cents enables an operator to play a single record, the device 38 may be programmed so that two records may be played for 25 cents, and five records may be played for cents. The decoder 35, which convertsthe binary coded signals to a monetary unit related signal, is employed to facilitate the programming of the device 38 since the use of a binary code at this point would make it difficult for a person adjustingthe machine to readily provide the desired code.

The sequencing switch may, for example, include a plurality of comparators, one for each I value to be tested, with each comparator being coupled to inhibit passage of signals through every lower valued comparator upon the occurrence of a signal in the higher value comparator. The sequential operation of testing the different values is, of course, dependent upon the subtraction of the detected high value from the storage register 4 to enable the sequencing switch to continue its testing, and this subtraction will be explained in greater detail in the following paragraphs.

The output of the conversion device 38 on the terminal P is thus in the form ofa parallel coded signal corresponding to the number of play units to which the operator is entitled. The outputs of the conversion device 38 are applied by way of separate AND-gates 42 and separate AND-gates 43 to the separate stages 44 of an intermediate play shift register 45, also referred to as the fourth register, the AND-gates 42 are gated by signals on a common line 46, and the AND-gates 43 are gated in common by the 1- signal. The data stored in the fourth shift register 45 is shifted out to one input of a full adder 50, the end of the shift register 45 not connected to the adder being connected to a logic 0 reference so that the shift register is reset after being read out.

The sum output of the full adder 50 is applied to one AND-stage 51 of a play shift register 52, also referred to as second register, the other AND-stage 53 of this register being connected to the full adder as the second input thereof. The operation in the serial full adder 50 is gated in the carry circuit thereof by the -r signal as indicated in the drawing. As a consequence, any data in the fourth or intermediate play shift register 45 is continually added to the contents of the second or play shift register 52, so that the play shift register continually stores the number of record play units to which the operator is entitled. ltis apparent that the operation of the shift registers 45 and 52 and adder 50is similar to the operation of the coin value intermediate storage register 17, coin value storage register 31 and full adder 38 as above discussed.

The outputs of the stages of the play shift register 52 are applied in parallel to a decoder circuit 55. The decoder circuit converts the binary signals applied thereto to a code more adaptable to the determination of the number of records that can be played.

In a typical jukebox, the records to be played may be assigned different values, so that it costs more to play one record than another. In the present instance, we shall denote the lower value record as a single selection and the higher valued record as a album selection. The necessary play units for these different types of selections are predetermined, and preferably adjustable as desired. In order to indicate to an operator that he has sufficient credit to play a single selection, and OR-gate 56 is connected to selected outputs of the decoder 55, the outputs corresponding to the minimum value, and theoutput of the OR-gate 5 6 is applied to an indicator 57 visible on the front of the jukebox. If there are insufficient credits in the jukebox for playing a single record, this is indicated on an indicator 58 activated from the output of the OR-gate 56 by way of an inverter 59. Similarly, suitable gatessuch as AND-gate 60 and OR-gate 61 are connected to. the decoder for indicating on an indicator 62 that there is adequate credit registered in the device for an album selection.

In the apparatus'according to the invention, several modes of operation are possible. The apparatus is provided with an or B" switch 70 which an operator controls to determine the side of the record to be played, and the device may also be provided with a credit option switch 71. in one form of operation, the operator inserts as many coins as he wishes, which may exceed the minimum value for single or album selections as much as he desires, and in this mode of operation the transfer of the contents of the coin value storage or first register 31 to the play shift or second register 52 will be effective only upon the operator controlling the A or B switch 70, so that the conversion of coin values to play units will be dependent upon the total value of coins stored in the coin value storage register 31 at the time the A" or 3" switch is operated. In another mode of operation, the credit option switch 71 will be closed, and in this case, the contents of the coin value storage register 31 are directly transferred to the play shift register 52 by way of the conversion device 38, in response to the insertion of a coin. The circuits employed for enabling these options of play will now be described.

Referring still to FIG. 1, the credit option switch 71 is connected from a suitable voltage supply 72 to one input of an AND-gate 73, the other input of the AND- gate 73 being a coin strobe output of the coin strobe generator circuit 11 online 74a. The output of the AND-gate 73 is applied by way of an OR-gate 74 and an AND-gate 75 to the set terminal of a flip-flop 76. The other input of the AND-gate 75 is controlled by the 1 signal for synchronization. When the flip-flop 76 is toggled by the coin strobe pulse and the credit option switch in this manner, the resulting signal on the credit comparison line 77 at one output of the flip-flop 76 is applied to the subtract terminal of the full adder 28. As a consequence, digits are subtracted from the coin value storage register 31.'The number of digits subtracted in this matter is controlled by the reset circuit of the flip-flop 76 which includes an OR-gate 78 and an AND-gate 79. The inputs of the OR-gate 78 correspond to the signals on the lines S1 S50 at the output of the sequencing switch, and each of these signals controls the OR-gate 78 for a number of clock pulses dependent upon the relative value of the signal. In other words, the S signals applied to the OR-gate 78 have durations corresponding to their respective values, the values being synchronized with the d) signal, and since the flip-flop 76 is set in synchronization with the 'r signal, the flip-flop will be reset in dependence upon the duration of the S signal so that a determinable number of pulses may be applied to the subtract input of the full adder 28. The AND-gate 79 is opened by the clockpulse for synchronization. Thus, in this mode of operation, since the coin strobe pulse on line 74 is responsive to the insertion of a coin, the detection of a high value by the sequencing switch 36 effects the subtraction of the related value from the coin value storage register 31, so that the play units may be shifted to the play shift register 52 and the coin value storage register 31 emptied as soon as possible. At this point it is to be noted that the credit comparison line 77 is connected to the line 46 which effects the opening of the gates 42, thereby permitting the output of the conversion device 38 to be applied to the intermediate play shift register 45.

It is to be further noted that the negation of the credit comparison signal, at the other output of the flip-flop 76, is connected to line 13 for controlling the opening of the gate 12, so that these gates, which pass the coin insertion signal to the encoder, can only be opened when the flip-flop 76 is reset, so that the device accepts only a single coin at a time. The time of operation of the flip-flop 76, however, is very short, so that no sequential insertion of coins in the jukebox will effect the accurate registering of all coins.

' If the credit option above discussed is not employed, the operation of the device may be dependent upon the control of the A or B switch 70. As shown in FIG. 1, the A or B switch is connected from a suitable source of voltage 80 to a strobe generator 81, the strobe generator producing an output pulse on line 82 which is applied to the other input of the OR-gate 74. In this case, the remainder of the operation of the device is the same as above discussed, the only difference being that the coin value shift register 31 is not emptied until the switch 70 is operated, so that the conversion in the conversion device 38 is dependent upon the total value of coins in the register 31.

The credit comparison line 77 is also applied in common to one input of each of a plurality of AND-gates 85 connected to the OR-gates 14, for a purposethat will be described in greater detail in the following paragraphs. In addition, the line 77 is connected to supply an input to the coin strobe generator circuit 11.

It is further evident that operation of the device of FIG. 1 is dependent upon the subtraction of play units from the shift register 52 as selections are made. For this purpose, the output of the strobe generator 81 is also connected to one input of a flip-flop 86, one output of the flipflop 86 being connected by way of AND- gate 87 to a flip-flop 88, with one output of the flip-flop 88, i. e. a subtract output, on line 89, being applied to the subtract input of the full adder 50. The flip-flop 86 is reset by a one bit delay circuit 90 connected from the output of the AND-gate 87 to the other input of the flip-flop. The flip-flop 88 is reset by a signal from the output of a signal generator 91 connected to the output of the one bit delay circuit 90, the signal generator 91 providing an alpha output signal for use in the control of the jukebox itself in the initiation of carriage movement. The output of the signal generator 91 applied to reset the flip-flop 88 enables the subtraction of a single bit from the play shift register 52.

As discussed above, the outputs of the AND-gates 85 are applied to separate inputs of the OR-gates 14, and thence to the encoder 15. The other terminals 95 may be connected by suitable means, for example, switches (not shown) to enable the addition of coin value units in the coin value registers without a necessity for insertion of coins. For example, such switches may be key operated switches controllable by an owner, for the purpose of enabling the storage of more play units than corresponds to the coins actually inserted in the device. This, of course, is another optionin the control of the system.

In the arrangement as above discussed, an amount was subtracted from the play shift register correspond-- ing to a single record. When an album selection is made, however, more units must be subtracted from the play shift register, but this cannot be done solely on the basis of the operation of the A or B switch. In order to subtract the play units from the play shift register corresponding to the actual album selected, Or-gates 96, 97, and 98 are provided in three ofthe lines between the AND-gates 42 and AND-gates 43. The other inputs of the OR-gate's 96 98 are connected respectively to the outputs of AND-gates 99, 100 and 101. The circuit is further provided with an album value input code circuit 102, with one output of the circuit 102 being connected to a coding circuit 103 connected to selected inputs of the AND-gates 99 101. The subtract signal, from the flip-flop 88, is also applied to the coding circuit 103. When an album has been selected, dependent upon the operation of conventional switches in the jukebox, the selection of the album is transferred to the circuit of FIG. 1 on terminal 104, i. e. an indication that an album has been selected. The terminal 104 is applied to the coding circuit 103 by way of a pair of shift register stages 105 which are shifted in response to the selection of the second digit in the jukebox. (In jukeboxes the operator conventionally selects two digits corresponding to the different records, as well as A or B signals corresponding to the sides of the records). Depending upon the selection of the second digit, the code circuit 103 applies suitable signals to the AND- gates 99 101 and thence to the OR-gates 96 98 to effect the subtraction of the correct number of play units by means of the intermediate play shift register 45 and the adder/subtractor 50 from the play shift register 52. The output of the input code circuit 102 is also applied to the gate circuit including gates 60 and 61 which indicate the presence of adequate play units to play an album, so that the album indicator may be controlled also in response to the particular album selected, i. e., so that albums of different values may be employed, and if a higher value album has been selected, the indicator 62 will indicate whether or not the higher valued album'may be played.

Still referring to FIG. 1, additional functions may be obtained in the circuit by providing additional inputs 1 10 connected by way of suitable pulse filtering circuits 111 to the gate 19. These inputs may be responsive by a desired means to the insertion of coins in the apparatus, and may if desired also be connected to effect the storage of the information relating thereto in the suitable manner,

The reset input of the coin strobe generator circuit 11 is also connected to an input of the OR-gate 19, by way of a filtering circuit 1 12, although this filtering circuit is adapted to pass pulses of about one tenth the duration of the pulses applied thereto by way of the filters 20.

FIG. 3 illustrates a strobe generator which may be employed for the A-B strobe generator 81, as well as for a portion of the strobe generator circuit 11. This arrangement comprises a shift registerof a plurality of stages with the last stage being connected to one input of a half adder 121. The outputs of all but the last stage of the shift register are applied as inputs to a NOR-gate 122, and the output of the next to the last stage of the shift register is also applied as a second input of the half adder. The sum output of the half adder is applied as one input to an OR-gate 123, another input being derived from the output of the NOR- gate 122. The output of the OR-gate 123 is connected to the input stage of the shift register. The stages of the shift register have common reset lines and common shift lines. When the circuit is employed as the strobe generator 81, the switch 70 is connected to energize the reset line, and the clock pulses energize the shift line. When the strobe generator is used in the circuit 11, the output of the OR-gate l9 energizes the reset line, and the clock pulses energize the shift line. The output terminal 124 of the strobe generator of FIG. 3 is connected to the output of the NOR-gate 122.

In one embodiment of the coin strobe generator circuits 11, as illustrated in FIG. 4, the OR-input from the OR-gate 19 is applied to a strobe generator 130, for example the strobe generator of FIG. 3, the output of the strobe generator being connected to the set input of a flip-flop 131. The reset input of the flip-flip 131 is synchronized with the 'r and clock pulses,for example by means of an AND-gate 132. The output of the flipflop 131 and a r pulse are applied to separate inputs of an AND-gate 133. The output of the AND-gate 133 is connected to one input of an AND-gate 134 and one input of an AND-gate 135. The reset input to the circuit 11 is connected to the other input of the AND-gate 135. The output of the AND-gate is applied to one input of a flip-flop 136, one output of the flip-flop 136 being connected as a second input to the AND-gate 134. A negated reset input is applied as a third input to the AND-gate 134 by way of an invertor 137 connected to the reset inputs of the circuit, and the fourth input of the AND-gate 134 is connected to the negated credit comparison terminal 138 derived from the flip-flop 76 of FIG. 1. Still referring to FIG. 4, the output of the AND-gate 134 constitutes the coin strobe output for application to line 74, this line further being connected to the other input of the flip-flop 136 and to an input of an OR-gate 139. The output of the OR-gate 139 constitutes the C and S strobe output of the circuit applied l 1 to line 21. A further input to the OR-gate 139 is constituted by an AND-gate 140 having as inputs the credit compensation signal from line 77, the subtract signal from line 89, and the,coincidence of the 1' and clock pulses. The circuit according to the invention may be further provided with a money value counter 150 as illustrated in FIG. 5, for storing the coin value credit, the circuit 150 being adapted to be connected externally to a credit memory, for example, for driving a coin counter or register. As shown in FIG. 5, such circuit may constitute a divide-by-two divider and control circuit 151 to which a Hz strobe signal from source 152 is applied. The credit compensation signal and coin signal from the circuit of FIG. 1 are applied' to an AND- circuit 153, the output of the ANDcircuit 153 and an output of the divider circuit 151 being applied as one input of a full adder 154 by way of an OR-circuit 155. A subtract input for the full adder is derived from the divider circuit 151. The sum output of the full adder 154 is applied to one end of a shift register 156, the other end of the shift register being fed back to the full adder 154 as the second input thereof. The output of each of the stages of the shift register are connected by way of an OR-gate'l57 to the divider 151. A negated C and S strobe pulse is applied to the divider 151 as a further input and the output of the divider is connected to a sum counter 158 operating at lOHz.

A further circuit employed in combination with the arrangement of FIG. 1 is illustrated in FIG. 6. FIG. 6 illustrates a control gate 160 having single and album" inputs 161 and 162 respectively. These inputs are responsive to the selection by the operator of a single record or an album record in the jukebox. The system of FIG. 6 is employed to determine, after checking of the play shift register 62, whether the selection made by the operator is to be permitted or not. in the event that this comparison indicates that not enough credit is available in the device to play the selected record, the control gate 160 provides an inhibit output to prevent operation of the jukebox. For example, the circuit may inhibit the operation of the record carrier. If there is a malfunction in the apparatus, this may be signalled to the control gate 160 as a not allowed input, which also provides an inhibit output to prevent operation of the device. The album input on line 163 may be derived from the circuit of FIG. 1 for comparison in the control gate 160. The details of the control gate 160 do not form apart of the present invention and this system has been presented, primarily in order to clarify the operation of the system of FIG. 1 when employed in a jukebox.
