  • the construction and operation of the circuit 72 are important to the invention and several different embodiments will be described.
  • the selection interface 74 is preferably formed using high input impedance optical coupling devices which provide a low condition as seen by the price matrix 54 and provide any combination of lows to price inputs S S of the comparator circuit 36.
  • the circuit of these coupling devices is shown in FIG. 17 and will be described later.
  • the carry output (C 64 and the B 0 output 66 are both in low conditions providing lows to both inputs of the OR gate 68. This produces a low on the gate output lead thereby removing the high that was present on the reset input R of the logic circuit 72.

This assures that only one selection will be allowed at any one time regardless of how many are possible to make.
  • the lows produced on the logic output leads 116-122 are used to energize respective vend relays 116A-l22A all of which have their opposite sides connected to a common high voltage input.

  • the circuit 134 then applies its output to the first stage S input 136 of the logic circuit 72. This signal indicates that the vend has been successful or has been successfully initiated, and as soon as the vend operation is completed the output on lead 138 of the circuit 72 will go low for the purpose of initiating a change making operation if one is required.
  • the A B output 56 of the comparator 36 will be low and will prevent the reset R input 38 of the comparator 36 from going high until the payout pulsing is completed.
  • the payout pulsing is from pulse payout circuit 140 under control of payout switch 142 and is applied to the payout input C 40 of the comparator logic 36 to increase the amount entered into the register from the price matrix 54 until it equals the amount accumulated and entered in the comparator A register from the coin accumulation circuit 30.
  • the A B output 56 will go high and cause the AND gate 58 to provide a high to the R reset input 38 to reset the coin accumulation A register.
  • vend selection is made possible and the power to produce the vend is provided through a common connection under control of the four vend lines 8490 and the associated terminals 7682.

  • the A,-A inputs to the full adder 150 are in their binaryv (11111) state because of the connection of the A register inputs to the positive voltage source, the B,B adder inputs at reset are at (00000), and the sum adder outputs at S,-S are therefore (11111) with a carry out condition of (0).
  • the A,-A inputs at reset are in the condition described because of the connections'to a positive source to the A register inputs 156-164 and the A register is held in its reset condition by ground connections to the C and R terminals 210 and 212 as shown in FIG. 1.
  • FIG. 4 shows what happens to the sum outputs at 8 -8 which become 11110 with a carry out logic 1 also present on output lead 124, when a logic 0 input is present at vend selection terminal 76.
  • This condition 5 will occur when vend selection switch 144 is activated and causes a logic 0 to be present at terminal 76.

This in turn removes the forced logic 1 from being applied to B register input S by way of another diode 248 to provide a logic 0 by way of resistor 250 from the nickel enable input. This completes the function as shown in FIG. 14c.
  • the time delay provides that the vend output will remain on for a delay period as determined by the delay means 240 and will remain on for the delay period before quarters are attempted to be paid ahead of dimes, and thereafter nickels.
  • the diode 244 and the resistor 246 provide an AND function so that the adder output at terminal S which is in response to a dime enable input, must go to logic 0 before register input S will go to a logic 0.
  • the diode 248 and the resistor 250 provide an AND function from the adder output S to the register nickel input at terminal S
  • Other resistors 252 and 254 are connected respectively between the adder outputs S and S and the B register direct set inputs S and S and they function in manners already described.
  • the present system offers an extremely large number of control possibilities, but it also offers the possibility of establishing priorities and priorities of sequences which may be useful in situations such as are described above to establish sequencing priorities whereby a payback function takes place in the least possible number of coins and in a way which tests each succeeding higher order coin denomination as to its availability, moving to test each lower coin denomination in a particular order of priority and on a delayed sequence basis.
  • FIG. 17 shows the details of a particular embodiment of the selection interface and delivery or reset interface circuits 74 and 134.
  • the vend selection inputs at terminal 76 are applied to a circuit which includes a capacitor 270 connected in parallel across a diode 272 in series with the light emitting portion of an optical coupling device 274.
  • the opposite side of the parallel circuit is connected to one side of a resistor 276 which is connected to an intermediate location in a voltage divider circuit across the power supply formed by diode 278, resistor 280 and a parallel circuit formed by resistor 282 and capacitor 284.
  • the capacitor 284 has a charge that is about equal to the voltage across the power supply.
  • the charge present on the capacitor 284 will discharge through a low impedance circuit formed by the resistor 276 and the circuit which includes the light emitting diode 274 causing the light emitting diode to emit light and to activate the associatted phototransistor portion 288 thereof.
  • the phototransistor portion 288 of the optical coupler 274 is physically located in the same envelope with the light emitting diode portion but is connected in another circuit which includes another diode 290 which has its opposite side connected to the direct set input S of the B register 152 in the vend payout control logic circuit 72.
  • the adder output S which is effected by a signal on S is also connected through resistor 292 to the same direct set input S and operates in a manner already described.
  • Similar circuits are included in the selection interface circuit 74 in association with each of the other input connections 78, 80 and 82.
  • Each of these circuits has its own optical coupler formed by a light emitting diode and associated phototransistor connected in a manner similar to that described in connection with the input circuit for the terminal 76, and it is not deemed necessary to describe each of these circuits in detail since they operate in the same way all using the capacitor 284 as the source of charge to energize the respective light emitting diodes.
  • the input terminal 128 is connected to one side of the power supply through a circuit which includes another capacitor 294 in parallel cross diode 296 in series with light emitting diode portion of another optical coupler 298. This circuit also includes another resistor 300. The input terminal 128 is also connected through the one or more coin return electromagnet coils 302 and 304 to the opposite side of the line at terminal 306.
  • the carry out C terminal of the circuit 72 is connected to lead 124 and has a connection to one side of the transistor portions of the four light emitting diode portions of the optical couplers associated with the input terminals 76, 78, 80 and 82 so that whenever the lead 124 is at a logic 1 condition it prevents or inhibits any further input signals from effectively actuating the selection interface circuit 74 in the manner indicated. This is because when lead 124 is at logic 1 it will then no longer be possible for a signal to be applied to the 12 corresponding direct set inputs S -S D5 of the B register 152.
  • the subject control system differs from prior art systems including the one disclosed in Applicants own pending U.S. patent application Ser. No. 381,900 now U.S. Pat. No. 3,841,456 in that it includes many other features and is able to perform many more control functions. This includes being able to provide multiple vend control functions utilizing a unique combination of a full adder, a binary register, and interconnecting circuitry. None like this is disclosed in the prior art.
  • the subject system can also be used with any other accumulation and price selection circuits including those shown in Applicants pending applications, and in many other systems for that matter, and when this is done it provides versatile means to accomplish simple as well as complex control functions including simple and complex vending control and change making functions.
  • circuit means shown in FIG. 17 represent an important more versatile improvement over selection monitoring means such as shown in Applicants pending applications Ser. Nos. 381,900 and 331,380 now U.S. Pat. Nos. 3,841,456 and 3,828,903 respectively.
  • the present circuit employs a capacitor which is charged and remains charged because of the way it is connected to the line voltage, and it discharges through a selected light emitting diode only when a selection circuit is closed by operation of a selection switch under control of the customer.
  • a capacitor is charged through circuit means only after a selection switch is closed. This is opposite from the present capacitor charging circuit and is an important structural and operational difference between them. This is important because it means that the capacitor in the present circuit is always ready and able to discharge immediately and in a very short time duration and is able to provide sufficient current flow through the selected light emitting diode to perform its necessary functions.
  • the capacitor discharge cycle (time constant) dictates how long the light emitting diode will be signaled or energized, and without having to have the light emitting diode look through a capacitor to a power source as in prior constructions but instead has the diode look to a capacitor that has already looked through to the energy source and been charged thereby.
  • the present circuit teaches a different technique to interface input signals in a control circuit including reset input signals used to terminate a vend operation and signals used to control the change over from a vend to a payout operation.
  • the present circuit also utilizes the same power supply line which controls the energizing of the coin return electromagnets (CREMS) to charge the capacitor, and the light emitting diode portion of the optical coupler 298 which operates in the circuit with the CREMS when deenergized by removing the line voltage appearing on the lead 310 from the opposite side of the line voltage which appears at terminal 306.
  • the lead 128 is always connected to the lead 310 and to the lead 312 through the CREM coils 302 and 304. This means that when the CREMS are energized they will remain energized until the lead 128 opens which occurs at the time a product is being delivered.
  • the optical coupler 298 will be shorted out until such a time as the input on lead 128 is open as explained, and thereafter the lead 128 will no longer be shorted and will draw current through the CREMS 302 and 304 sufficient to activate the light emitting diode 298 but not sufficient to energize the CREMS. -For these reasons the present circuit is substantially different from anything known heretofore including the circuits shown in Applicants own previous cases.
