Description

In a vending machine, a large denomination coin is intended to be temporarily withheld if it is considered to be Exchange coin among the inserted or deposited coins and the supply coins of small denominations in coin stacking tubes is not usable. If the deposited money is to be returned, coins with the same denomination as the inserted ones are inserted Small denomination coins paid out from the coin stacking tubes; also the withheld coin with 'large Normal value is then returned. When the vending machine is short of change coins, it sells the desired item only if a coin is inserted that does not require changing; it automatically returns the deposited coin.

509843/0242

when a coin is inserted that requires a change.

. The vending machine is supposed to have a coin, the same

Face value like the coin used in the vending machine has to be able to return it in an error-free manner if the coin has been inserted into the machine but has to be returned, because the purchase of the goods is not carried out for one reason or another; there should also be change either in coins large face value or in small face value coins and the inserted coin will be returned if the Machine is running out of change.

In known vending machines, the return of Money, the sum of which is equivalent to one imported coin for those cases when the purchase of the goods is not carried out has been achieved by using coins stored in an exchangeable coin stacking tube. When a Amount of money to be returned equivalent to a inserted large denomination coin such as 100 yen, but the coin with the same denomination is not stored in the change coin stacking tube as change Small denomination coins such as 1o yen or 5o yen can be used. This causes a shortage of change; when a If such a shortage is to be avoided, the vending machine requires a long exchangeable coin stacking tube.

509843/0242

Another disadvantage of such a known vending machine is that a return instruction is issued can before the amount of the inserted coin is determined electrically, if a return button immediately after Inserting the coin into the machine is pushed, causing shortage or even complete lack of returnable items Money occurs.

In order to avoid a shortage of change, another known vending machine uses a construction which temporarily withholds an inserted coin and then forwards it to a coin container when the purchase is made is carried out, or returns if it is to be reimbursed. However, this vending machine requires a large one and complicated mechanism for holding everyone back

inserted coins. In addition, the retained Coins in this vending machine not as change be used.

Another well-known vending machine holds all thrown in Coins temporarily returned by coin type? he then returns them when they are to be reimbursed and directs them to a change stacker tube when the purchase is complete. However, this vending machine also requires one complicated coin retention mechanism and also has the Disadvantage that coins are jammed in a coin channel of the machine, which results in incorrect operation of the machine results because a relatively large number of coins at the same time

5098 A-3/0242

from the coin retention unit to the change stacking tubes.

; The object of the invention is therefore to create a vending machine that is reliable in every respect works and is independent of the number, size and time interval of the introduced coins, while the amount and type (face value) of the inserted coins can be counted and stored, so that one or more coins with a large denomination under the inserted coins can be temporarily withheld, while the coins with small denominations in one for each coin denomination provided exchangeable coin stack tube are stored and the machine is able to the retained coin with a large face value as well as the same face value of coins as the inserted coins with a small face value from the Return the exchangeable coin stacking tube. Each time a coin is returned, the value of the coin is deducted from the total amount entered Coins withdrawn; the coin return process is ended when the difference becomes zero. With a control system, a sell signal is independent of the amount of stored Change is generated when an inserted coin does not change money requires; if the inserted coin requires currency exchange, a coin with the face value of the inserted coin will be used ! Hinze only returned when the machine is short of change. The control system operates a coin return mechanism, if the value of the inserted coin or coins coincides with a fixed selling price, or when a return button is pressed in order to obtain return of coins subsequently inserted into the machine. It will

509843/0242

a subtract, change, or return command given with a delay of a predetermined period of time after a sell order signal or a return signal has been obtained to provide accurate detection, sales and

To ensure the return operation of the machine and thereby exclude incorrect operation of the machine. So a plurality of pieces of the same commodity can be sold with a single coin deposit; it can also be a A plurality of different types of goods are optionally sold. Adverse noise effects can be effectively prevented; Incorrect ways of working when switching on energy are completely excluded. The probability of wrong counting if different denominations of coins are simultaneously determined by the detection switch, this is eliminated. A deposit liability device holds one sorted out by a coin acceptor among the inserted coins and not as change used coins with a large face value temporarily back, with such a reluctance of the coin through return and acceptance levers is effected in entrances of a coin path leading to a return outlet and one to a coin container leading path can step forward and then the retained coin to the return path by retracting the Return lever, when the coin is to be returned, and to the coin container by pulling back the acceptance lever ^ lead when the purchase is made. This results in optimal sales promotion and operational reliability.

According to the invention, this object is achieved by a transducer, 509843/0242

the coins of at least three different denominations of first, second and third rank can sort out and has coin paths, the coins of the second and third rank below, the coins deposited in the receiver and sorted out by this guide in positions above their respective coin tubes, devices for preventing the Feeding the second and third tier coins to the coin tubes when the coin tubes already contain a predetermined number of coins and a first for passing the second and third tier coins to the coin tubes when the coin tubes contain less than that predetermined number of coins A path leading the blocked coin to a coin container, a second path leading the coin of the first order to the coin container, a third path leading from a predetermined position of the second path to a return outlet, means for temporarily retaining said coin e of the first order in that first and second levers project into and out of said second path at the predetermined position, the retained coin being moved to the third path by withdrawing the first lever and to the coin container by withdrawing of the second lever is passed, and coin payout devices for paying out individual coins, which are required for exchange or return purposes, successively released from the coin tubes containing the coins of the second and third rank.

In a special embodiment, the sales number is 509843/0242

The control system of the vending machine according to the invention is now with reference to the circuit diagram of 'Fig. 2 described in detail.

The reference symbols S, S "and S ;, denote switches which are operated accordingly in that they run through them sorted out coins by a Münzenauf taker A (referred to here as" taker ") in order to determine the input or the insertion of the coin. In the illustrated embodiment, the switch S. is set up to detect a 100 yen coin, the switch Sp * ^da ^ ^er

509143/0242

50-yen coin, and the Sehalter S- ,, that he has one 10 yen coin notes. The switches S., S "and S are to the pulse control unit PC via respective inverters 1, 2 'and 3 and shock or bounce prevention circuits 4, 5 and 6 connected. The switches S ^, Sp and S, apply high-level signals to the inputs of the corresponding inverters 1, 2 or 3 in the one shown in the figure State on. If the switches S ^, Sp and S at Detection of the coins are actuated, signals with low levels reach the inputs of these inverters 1, 2 and 3 · In the following description, a high level is with "1" and a low level is shown as "O".

The pulse control unit PG is adapted to generate pulses of predetermined different pulse widths in response to coin detection signals supplied from the switches S ^, Sp and S i. ^{When the switch S is operated 1} 'when a 10-yen coin is inserted, that a signal "1" is applied to a terminal T, the pulse control unit PG, this generates a pulse A with a width as shown in Fig. 4- is shown. When the switch S ^ ^ ei ^m inserting a 50-yen coin operated, so that a "1" signal Tp is applied to a terminal, the pulse control unit erzeiigt PC a pulse B having a width as shown in FIG. 4 is. (This pulse width is five times that

509143/0242

long as the width of the impulse A.) In the same way, if a 100 yen coin is plagued, an impulse C with a Width is generated, as can be seen from Fig. 4-.

A preferred example of the circuit structure
such a pulse control unit PC is shown in FIG. The structure and operation of this pulse control unit
will now be described.

An OR circuit OR _x . receives a coin detection signal supplied by terminals T _x and coin detection signals supplied via OR circuits ORp and OR from terminals Tp and T-. When a signal "1" representing the detection of a coin is applied to one of the terminals T _x . - T ^ given wiri, the OR circuit OR _x generates a signal "1",
dao to the Ein ^ angsklerame. a flip-flop circuit DF _x . an- ^ ele ^ t will. The flip-flop circuit DF _x . receives such a work pulse WP, as shown in FIG. The flip-flop ochaltim ¹ · -; DF _x , saves the signal "1" and gives it on receipt of a f ^ Tit ^ n work pulse WP (the first word) from un-i then sets the read output signal "1" on receipt
'"in the next' \ rarbeitnimpulses WP (the second word) back, Ia] In a ζυ ilior-e." /. since applied to its input terminal
wir-nal is "0". .Jot- · Output of the flip-flop circuit DF _x . is ■ in a; ler Είηρ inrsklemmen an UlTü connection AND _x , and

Ί 8 ^ 3/0242

also applied to the input of a flip-flop circuit DF ₂ . This has the same structure as the flip-flop circuit DF _x .. The output of the flip-flop scarf tune; DFp, which is still "0" in the first word and becomes "1" in the second word, is applied to the other input of the TItTD circuit AND. via an inverter IN. created. As a result, both input signals of the AND circuit AND ^ at the first word "1", ^-1 SO that the AND circuit AND _{1 is} a signal "1" during a period between the generation of the first working pulse WP and the generation of the next working pulse WP (referred to here as "word time"). This output signal "1", which represents the fact that a coin with a denomination has been introduced into the machine, is applied to an AND circuit AND ₂ via an OR circuit OR _2,. This output signal "1" of the AND circuit AND. has a pulse width completely equal to the width of the pulse C in Fig. 4-.

The AND circuit AND _{2 also} receives the output of an inverter IN ₂ . This output of the inverter IN ~ is only "0" when a signal "1" is applied either from the OR circuit ORp to an AND circuit AND, - or from the OR circuit OR, to an AND circuit AND ^ to cause the AND circuit AND ₅ or AND ^ to turn on the "1" signal. As a result, when the 100 yen coin determination

5 0 S § £ 3 / $ 2 4 2

switch S. is operated, so that a signal "1" to the Terminal T ^ arrives, the output of the inverter INp "1", and the AND circuit ANDp switches the output signal "1" from the AND circuit AND. by. Because the output of the AND circuit ANDp represents the output of the pulse control unit PC, is a pulse signal having a pulse width of 1 word time, as shown in Fig. 4- as C, from the pulse control unit PG upon determining the use of a 100 yen coin generated.

When the 50-YenrMünzen detection switch Sp is actuated so that a signal "1" is applied to the terminal Tp, the signal "1" from the OR circuit OEP to one of the input terminals of the AND circuit AND ₁ is. created. In the meantime, as shown in Fig. 4, a pulse DT ₁ successively is applied to the other input terminal of the AND circuit ANDc. As a result, the AND circuit generates AND, -a pulse signal having a pulse width equal to the width of the pulse DT _n . is when the two signals are given simultaneously to the inputs of the AND circuit AND, -; the. This signal "1" arrives at the input of a flip-flop circuit DF, via an OR circuit-OR ₁ .. The flip-flop circuit DF receives a constant pulse DP (Fig.4 ·), 'the one Has a period of one tenth of the period of the work pulse WP. The flip-flop circuit DF stores the

509843/0242

Signal "1" of the OR circuit OR ₅ and emits it on receipt of a first pulse DP and resets the signal "1" on receipt of the next pulse DP. As a result, the output of the flip-flop circuit DF is "1" while the pulse DP is between 5 DP and 6 DP. This signal "1" is applied to the inverter INp and to one of the input terminals of an AND circuit AND. Then a pulse ΒΊ * (Fig. 4) is passed to the other input of the AND circuit AND, via an inverter IN. Since the pulse DT- _{Q is} not generated at the pulse 5 DP, the AND circuit supplies AND, an output signal "1". This output signal "1" reaches the flip-flop circuit DF via the OR circuit ORj-. As a result, the output signal is "1" of the flip-flop circuit DF, latching after the pulse 6 DP. This state is canceled when the pulse DT ^ iQ reaches the inverter IN. In this way, the output of the inverter IN becomes "0" substantially after the pulse DP. The AND state of the AND circuit AND ^ "is achieved only during a period between the generation of the pulse C shown in FIG. 4 from the AND circuit AND. And the effective generation of the pulse 5 DP, and the pulse control unit PO generates a in Fig. 4 with B designated pulse signal during this time.

When the 10 ten coin detection switch S,

509843/0242

is actuated so that a signal "1" arrives at the terminal T 1, this signal "1" is passed to one of the inputs of an AND circuit AND ^ via the OR circuit OR. Since a pulse DT ,. (Fig. 4) is at the other input of the AND circuit AND ^, this generates a pulse with the same pulse width as that of the pulse DT. If it receives two input signals at the same time. This output pulse of the AND circuit AND ^ arrives at the input of T) W ₇ . via the OR circuit 0R _r . For the reason described above, the output of the flip-flop circuit DF-, essentially after the pulse 1 DP "1", so that the output of the

Inverter IN ₂ becomes "0". The AND state of the AND circuit ANDp is therefore only achieved during a period between the generation of the pulse denoted by 0 in FIG. 4 from the AND circuit AND, and the effective generation of the pulse 1 DP, \ md the pulse control unit supplies a pulse signal, denoted A in FIG. 4, which indicates the determination

I, *

the use of the 10 yen coin.

As will be described in detail later, pulse signals corresponding to the denominations of the coins used are also generated by the pulse control unit PC when the coins are to be returned. In this case, signals from AND circuits to be described later are used. 41, 44, 45 and 51 to the OR circuits OR ₂ , OR and.OR ^ the

5098

Pulse control unit PC applied. The output of the flip-flop _{circuit DF 2} is given to an OR circuit OR ^, as a signal KP, as will also be described later. Furthermore, the output of the AND circuit AND ^ is fed to the OR circuit OR ^ and also to the terminal T ^.

Fun will be described with reference to FIG. 2, the construction and the mode of operation of the stages of the circuit arrangement located downstream of the pulse control unit PC. The output pulse from the pulse control unit PC is sent to the AND circuit AN. This also receives a pulse t ^, as shown in Fig. 4-. The AND circuit AlT switches through only one pulse of the pulse t ^ when the pulse A (FIG. 4) is received from the pulse control unit PC, ie when the use of a 10 yen coin is detected. This pulse t * is given to the addition and subtraction counter AS via the OR circuit OR. In the same way, five pulses of the pulse ι ,, run through the AND circuit AND to the addition and subtraction counter AS via the OR circuit OR when a 50-yen coin is detected. When the use of a 100 yen coin has been determined, ten pulses of the pulse t ^ are applied to the addition and subtraction counter AS via the AND circuit AN and the OR circuit OR.

If a 100 yen coin or a 50 yen coin is

is thrown, an impulse appears. G (Fig. 4) at a terminal T ^. If the inserted coin is a 100 yen coin, an AND circuit 58 receives the signal from the terminal T ^ and the signal from the terminal T _2,. The AND circuit 58 therefore produces an output representing the use of a 100 yen coin and this output is stored in a 100 yen coin memory 52. If the inserted coin is a 50 yen coin, an AND circuit 53 receives the signal from the terminal Tp and the signal from the terminal T ^ and produces an output representing the insertion of a 50 yen coin. This output is stored in a 50 yen memory 54.

From the above description it can be seen that the number of pulses corresponding to the quotient which is obtained by dividing the total amount of the inserted coins by 10 yen, to the input of the addition and subtraction counter A3 are applied. ·. '

The addition and subtraction counter AS receives an addition and subtraction control input from an inverter 7. The addition and subtraction counter AS performs addition when the control input is "0" and subtracting when the control input is "1" . The addition and subtraction counter AS is constructed in a conventional manner * and contains

50984370242

a shift register and a binary counter.

When a coin is inserted into the machine, the control input to the addition and subtraction counter AG is "0", as will be described later, and in this case the addition and subtraction counter AS performs addition. When all coins have been inserted, a value corresponding to the total amount of coins inserted is counted in the form of binary information in the addition and subtraction counter AS. Pp .... P [-. On the input side of the comparison circuit CM there is a plurality of EXCLUSIVE-OR circuits which receive _{these outputs P ^, P 2} ... P _{1 - at one of their inputs.} The other input terminals of the EXCLUSIVE-OR circuits are connected to the retail price setting circuit SS. This can set a sales price to a desired amount and supply binary signals corresponding to the fixed sales price to the EXCLUSIVE-OR circuits of the comparison circuit CM. The outputs of the EXCLUSIVE-OR circuits are connected to the input of an AND circuit CMA. As a result, the comparison circuit CM generates an output "1" _r when the count of the addition and subtraction counter AS with the fixed

503843/0242

set selling price coincides.

This output is stored in a memory 8 and also to one of the inputs of an AND circuit 10 passed through an OR circuit 9. Since at this time the AND circuit 10 at the other input has an output receives from the memory 8, the AND circuit 10 provides an output which is via a flip-flop circuit 11 to one of the inputs of an AND circuit 12 arrives. What time- . ter is described, a signal "1" is constantly applied to the " other input of the AND circuit 12 applied so that it emits an output "1", which the sales signal generator VE to Sending a sell signal initiated.

The output of the memory 8 is also given to the coin return solenoid CA. This return solenoid GA is provided to move a pin in and out of the coin path of a receiver A. When a signal "1" is applied to the solenoid OA, the solenoid CA is de-energized, so that the pin in the coin path of the pick-a projecting. as a result, a coin that has fallen into the coin path is blocked by the pen and returned to a Rückpjabeauslaß OUT. for example, if a Käiifer a 100-yen coin in. a price set by 60-Ten thrown in and then mistakenly

S09843 / Ö242

If a 10 yen coin has been inserted, this becomes 10 yen coin returned automatically.

When a buyer presses a buy button (not shown) after the sell signal is given by the sell signal generator VE, a predetermined sales item is delivered and the sales switch S ^ is operated at the same time. When the switch S ^ is toggled from the state shown in FIG. 2, an input to an inverter 14 * becomes "0", which then supplies an output "1". This arrives at a memory 15j in which it is stored. The output of the memory 15 is applied to a timer Ta via an OR circuit 16 to initiate a delay operation of the timer Ta. The timer Ta supplies a signal "0" when it is not in the operating state. This signal "0" is _{reversed by an inverter 1 ^ r 7} , and the inverted output "1" is _{reversed again by the inverter Ir 7} , so that a signal "0" is obtained. This "0" signal is sent to the addition and subtraction counter AS, causing it to perform its counting operation. After the delay operation, the timer Ta provides an output "1" which is output from the inverter Iy. " Is reversed and reversed again by the inverter I". As a result, a signal "1" is sent to the addition and subtraction counter AS, so that

509843/0242

this is prepared for the ^ subtraction operation. In in the meantime, the output "0" of the inverter 17 is on an AND circuit 19 is given. Since the AND condition of the AND circuit 19 is not met, the output is the AND circuit 19 "0" so that the output of the AND circuit 12 becomes "0", whereby the operation of the sell signal generator VE is stopped. Thus, the sales signal generator hears VE to generate the sell signal.

The output "0" of the inverter 17 is inverted by an inverter 18, and the inverted output "1" is applied to a timer T ^ - and also to one of the inputs of each AND circuit 20 and 21. The timer T _& supplies a signal "1" after a predetermined period of time to another input terminal of the AND circuits 20 and 21. The AND condition of the AND circuit 20 is not satisfied at the time at which the signal "1" is generated by the inverter 18 because the output of the memory 15 is at another input terminal of the AND circuit 20 via an inverter 23. On the other hand, the output "1" of the memory 15 is given to another input terminal of the AND circuit 21. This therefore gives an output "1" to the acceptance solenoid Ep in order to actuate it. When the acceptance solenoid Ep is operated, the pin PLp located on the coin box side in a device is turned over

509843/0242

to temporarily hold back a coin mechanically, withdrawn, and the temporarily retained coin is received in the coin box.

The output "1" of the AND circuit 21 is applied to a flip-flop circuit 26 through an OR circuit 25 and stored therein. The flip-flop circuit 26 provides an output on receipt of the pulse DP. This output of the flip-flop circuit 26 is fed back to this via the AND circuit 27 and the OR circuit 25 in order to fix the flip-flop circuit 26 in a latching state. The output "1" of the flip-flop circuit 26
is also given to a flip-flop circuit 28, whose
Output terminal is connected to one of the input terminals of an AND circuit 30 via an inverter 29. While the flip-flop circuit 26 outputs "1" and the flip-flop circuit 28 has not yet received the DP pulse, the inputs of the AND circuit 30 become "1", so that it generates an output "1". The output "1" of the AND circuit 30 is connected to AND circuits SP. - SP _n . of the subtraction pulse generator SP delivered.

As a result, the sales price setting circuit SS generates outputs upon receipt of the timing pulses t ^ | - te, whereby a value corresponding to the sales price

50984370242

is subtracted from the count of the register of the addition and subtraction counter AS. If the sales price and the nominal value of the inserted coin coincide with one another, all outputs P ^, - P ₁ - of the corresponding stages of the register of the addition and subtraction counter AS are "0", and the entire circuit is reset. A reset circuit RG- is provided for this purpose. The reset circuit'RG receives the signal P ^ - P, - and generates a signal Rc when all input signals P _x , - Pj- are "0". This reset signal Rc is sent to each. Memory and applied to each AND circuit of the circuit arrangement.

In this way, the count amount of the addition and subtraction counter AS becomes a difference obtained by subtracting of the fixed selling price is obtained from the if value of the coin used. If this value is not zero, a sum corresponding to this value must be paid out as change.

The change paying operation will now be described. taking a case where the price is 120 yen and two 100 yen coins are deposited as an example have been,

509843/0242

Referring to Fig. 2, the count of the addition and subtraction counter A3 is 80 after pressing the sales counter S ^. A detection device FD determines whether the change to be returned is 50 yen and whether it is more or less than 50 yen. The detection device FD is so arranged that it receives the outputs P1, - P, - of the addition and subtraction counter "AS" and provides an output "1" when its count is 5 or more (that is, when the change is 50 yen or more), and "0" when its count is 1, 2, 3, or 4 (that is, when the change is less than 50 yen). The output of the detection device FD is applied to one of the inputs of a UITD circuit 3I. The other input of the AND circuit 31 is connected to a switch 8 ″, which is used to determine whether the 50 yen coin tube is empty or not empty. As a result, the AND circuit ¹ receives a signal "1" when a 50-yen coin is in the 50-yen coin tube, and passes a signal "1" to a memory 32 when the change is 50 yen or is more. The signal "1" stored in the memory 32 excites the electromagnetic control unit FS via an OR circuit 33. In the meantime, the output signal "1" of the flip-flop circuit 28 is transferred to one of the inputs of an AND circuit 35 an OR circuit

509843/024

created. Since the output of an inverter 36 is "O" and the output of a flip-flop circuit 37 is "0" when a Wechselgeldauszahlschalter S _n in the example shown in Fig. 2 state, an output ^Ir 1 ". An inverter 38 is applied to one input of the AND gate 35. This then produces an output "1" which is fed to a motor control unit 39 for actuation of the motor control unit 39. If a 50 yen coin is used as part of the required change has been delivered, the switch Sq is switched to a position in which the output of the inverter 36 is changed to "1." This output "1" reaches one of the inputs of an AND circuit • 4-1 via a Shock or bounce prevention circuit 4-0 and a flip-flop circuit 37. ^ a flip-flop circuit 4-2 outputs an output ¹¹ O "until it receives a pulse WP, an output" 1 "of an inverter 4 becomes -3 is applied to the other input of the AND circuit 4-1. This therefore produces an output "1" which is given to one of the inputs of each AND circuit 44- and 4-5. Since at this time the AND circuits 44 and 4-5 receive the output "1" of the OR circuit 33 at their other input, the AND circuit 44- provides an output "1". This output goes to the pulse control unit PC and produces the same result as if there were a 50 yen coin in the machine. was thrown in. As a result, the Impmlssteuer-

unit PC a signal B shown in Fig. 4 to the AND circuit ON, and five pulses are applied to the addition and subtraction counter AS via the OR circuit OR! ' Since the addition and subtraction counter AS is in a subtraction mode at this time, causes the counter AS performs a subtraction by reducing its count to 3.

This causes the output of the locking device FD to "0" soothes, whereby the electromagnetic control unit.FS is de-energized. In other words, the The change payout mechanism operates in a 10 yen payout mode brought. In this way, one 10 yen coin is dispensed with every revolution of the change motor in the in the same manner as previously described, while the output "1" of the AND circuit 41 is supplied to one of the inputs the AND circuit 45 is applied.

ι /

The output "0" of the OR circuit 33 is from a Inverter 46 reversed, and the output "1" of inverter 46 is given to the other input of AND circuit 45. This therefore emits an output "1" which is applied to the pulse control unit PO, with the same result appears as if a 10 yen coin was inserted into the machine. The pulse control unit PC supplies a shown in FIG.

509843/0242

set signal A to .the AND circuit ON. Consequently a pulse arrives at the addition and subtraction counter AS via the OR circuit OR, whereby the counting amount of the Counter AS is reduced to 2. 1O yen coins are consecutive supplied in the same way until the entire circuit arrangement is received on receipt of a reset signal Rc is put out of service. This reset signal is generated when the count amount of the addition and subtraction counter AS has become 0. Thus, the change paying operation is completed.

Now the operation of the machine is shown for a case described in which the buyer has pressed a return button after inserting a coin into the machine.

When the return button (not shown) is pressed and the return switch B ₁ . has switched over as a result, an inverter 47 supplies an output "1" which is stored in a return signal memory 48. The output “1” of this memory 48 is applied to one of the inputs of a NAITD circuit 49. Since a signal "1" at the other input of the NAND circuit; 49 is at this time, it supplies an output "0". The Uli D conditions of AND circuits 19 and 12 are no longer met, so that the sell signal is interrupted. At the same time the output "1" of the '

Return signal memory 48 given to AND circuit 20, in order to satisfy their AND condition in a state in which the "sales counter S ^ is not in operation. As a result the output "1" of the AND circuit 20 is applied to the return solenoid E.

If the signal "1" is on the return solenoid E ^, the return pen PL. the device described above withdrawn for temporary reluctance, and the Coin temporarily retained is returned to a return outlet OUT.

It is now assumed that a 10 yen coin, a 50 yen coin, and a 100 yen coin have been inserted. In this case, the temporarily withheld 100 yen coin will be returned in the manner described above, while the 10 yen coin and 50 yen coin with a total value of 60 yen will be returned in the same manner as for change _e xirercien More "specifically, the output" 1 "of the AND circuit 20 is applied to a ■ Rückgafoestartspeicher 50th The off ^ on. ^ Ssignal of the memory 50 is passed to an AND circuit 51. The 100-yen coin insert memory 52 is designed so that it outputs a signal "1" when the output "1" of the memory 50 generated in response to the insertion of the 100-yen coin is passed through an inverter

509Ö43 / 0242 bad orhmnal

vice versa and then to the memory 52 via an AND circuit 62 'is applied as a read signal "O". When the signal "1" is applied to the AND circuit 51 from the memory 52 is, the AND condition of the AND circuit 51 is fulfilled, and a signal "1" is supplied from the AND circuit 51 to the pulse control unit PC.

· It is noted that the change payout mechanism is prevented from coming into the operating state when a signal "1" is read from the memory 52 by a signal "O" to one of the inputs of an AND circuit 64 · is passed through an inverter 63.

The pulse control unit PO then generates a pulse C, which is shown in Fig. 4 *. The addition and subtraction counter AS receives 10 pulses from the AND circuit AN and subtracts 100 yen. The subsequent return the 50-yen and the 10-yen coins are made in the same way as previously described with respect to the change dispensing process.

A signal that indicates it has been that the 50-yen coin and _r gjeben, is applied to a 50-yen use memory 54 of the pulse control unit PO via an AND circuit 53 is applied and stored in the memory 54-.

ί 5Q $ S43f / Q242

Since the output "1" of the AND circuit 4-1 through. an inverter 55 reversed and then to one of the inputs a UTTD_circuit 56 is given, the output 'der AND circuit 56 "0", and this signal "0" is used "to read the contents of the memory 5 ^. The read Signal "1" energizes the 50-yen 10-yen payout control unit FS through an AND circuit 57 and the OR circuit 33. The subsequent operation for returning the 50 yen coin is same as described with reference to the return of the 100 yen coin Surgery. Then the 10 yen coins are returned in the same way.

The operation of the machine in the event of a coin shortage in the coin tubes will now be described.

If the switch Sg, which determines whether the 1Q-Yen coin tube is empty or not empty, from the figure shown in Fig.2 has switched position shown, and to the OR circuit 9 provides a signal "O" in the event that the 10 yen coin tube none to deliver required change contains a sufficient number of 10 yen coins, this signal becomes "O" from the OR circuit 9 to the AND circuit 10 created. As a result, the AND circuit 12 does not output "1". In the meantime, an inverter generates 59 * to the switch 56 via the OR circuit 9

509843/0242

is connected, an output "1". This output is given to one of the inputs of an AND circuit 60. A Output "1" of the memory 8 goes to the other input of the AND circuit 60. This therefore provides an output "1" to the return memory 4-8 as a return structure signal.

It can be seen from the foregoing that the state in which the machine is short of change is the same as the state in which _{the return switch S 1} - is operated and the inserted coin is returned as in the case of the return mode.

While a coincidence signal is applied to the AND circuit via the ODEIi circuit 9, a signal "1" is still present at the AND circuit 10 when an oiraal "0" is applied to the ODET? Circuit 9 through the switch S. ^ is given. As a result, the sales signal continues to be generated, and the return process described above is not carried out.

FallG '3 i ° switches in their proper function have failed and only a "0" signal is applied, a 3; Ιτηη1 "1" is generated by the pulse control unit PO, as described above, and this signal "1" becomes on given the Münzriick ^ aborsolenoid CA. This causes, that the

509843/0242

The pin protrudes into the coin path of the receiver, so that all inserted coins are returned.

In the above embodiment, the coin receiving and change paying operations are performed by switching the vending switch S ₁ upon application of the output "1" of the AND circuit 12 to the vending signal generator VE. It is noted, however, that the same operations can be performed by giving the output of the IMD circuit 12 directly to the memory 15 as a sales instruction signal.

In the vending machine according to the invention The switches used do not need to belong to one contact type, but other switch types can also be used, such as a non-contact switch type, a proximity switch, and a phototransistor type switch can be used.

Fig. 5 is a block diagram showing another embodiment of the vending machine according to the invention. This embodiment of the vending machine is designed so that they have a plurality of one and the same Item type sells with a single coin deposit action.

509843/0242

In Fig. 5, the same components are from S ¹ Ig. 2 denoted by the same reference numerals. Main differences between the embodiments of FIG. 5 and FIG. 2

are that. in the former η units of pricing circuits CP, comparison circuits GM, sell signal storage control units CG and sales s signal generators VE are provided, these circuits, units and Encoders are distinguished from one another by index numbers of the reference symbols are, and that in the first-mentioned embodiment, the sell signal from the sales circuit directly to a Return and acceptance control unit ER via a terminal TE is created.

A current example of the circuit shown schematically in FIG. 5 will now be described with reference to FIG. 6, in which the same components from FIG. 2 are denoted by the same reference numerals.

When one or more coins are inserted into the slot of the machine, a numerical value corresponding to the nominal value of the inserted coin or the total amount of the inserted coins is counted in the form of binary information by a counter AS in the same way as before with reference to the in Fig 1 has been described. Outputs P _x ,, Pp .... P ₁ - of the counter AS

are given to comparison circuits CM., GMp ... CM. Each of the comparison circuits CM., CMp ... CM has a plurality of EXCLUSIVE-OR circuits on its input side. These EXCLUSIVE-OR circuits receive the outputs P ^, P ₀ ... P _n - at one of their corresponding input terminals and are connected to their other input terminals with price setting circuits Go _x ,, SSp ... SS. These price setting circuits are able to set fixed sales prices, and a sales price corresponding to the desired number of items is barked into each of the circuits So., SSp., SS in the form of binary information. To simplify the explanation, it is assumed that the circuit SS. Corresponds to a sale of one piece of the goods and a price for this one piece, and that the circuit SSp corresponds to a sale of two bridges of the goods and sets a price for two bridges and that the circuit SS sets a sales price for η pieces of the goods in the same way. Signals corresponding to the set prices are applied to the input of the EXKLTniVES-OR-circuits of the corresponding comparison circuits CM., CMp ... CM in the form of primary information (5 bits in the illustrated embodiment). The output terminals of the EXCLUSIVE-OR circuit on the comparison circuits CM., CMg ... CM are correspondingly connected to the inputs of AND circuits CMA,.,

... CMA connected. As a result, the comparison _{circuits CM ^ - CM n} generate a coincidence signal "1" when the count amount of the counter A3 coincides with the set "price.

If the comparison circuit CM. a coincidence signal is generated, it is stored in a memory 8 ^, the sales signal-ospeicher-oteuereinheit CG. stored and also to one of the inputs of the AND circuit 10 ,, the same unit CG _x , via an OR circuit 9 «| given. Since the AND-Gchaltunr; 10.-, also an output of the memory 8, - receives the AND circuit 10 ^ an output "1". This output "1" is passed through a flip-flop circuit 11 to one of the inputs of an AND circuit 12. The AND circuit 12 ^ constantly receives a signal "1" at the other input, and as a result, the AND circuit 12 generates a signal "1" which a sales signal generator VE. to issue a sell signal.

If the comparison circuits CMp-CM generate a coincidence signal, sales signal storage units CGp-CG-Jn are actuated in the same way in order to negate sales signal generator VRp-VE _n y. \ Iv generation of a sales signal.

Palls to the comparison circuits described above CM. - CM applied, set price signals as nK ', where K is a price for a single piece of the commodity and a = 1, 2, ... η, and the amount of the inserted coins, i.e. the counted vert of the addition iond subtraction s counts s, represented as χ (aK ^ x) is, all comparison circuits that receive a signal identifying a set price generate the is less than or equal to χ, coincidence signals, thereby causing the respective comparison circuits corresponding sell signals are generated. More precisely, when the oin retail price for a single item is set at 60 yen and three 100 yen coins in are thrown into the vending machine, all sales signal generators deliver VE. - VE, - their corresponding sell signals.

The reason. for 'this use the one described above Construction in which a plurality of sell signals in Correspondence with the total amount of inserted coins is produced, is that the number of to The delivering article cannot necessarily be determined at the time at which the buyer has inserted the coins Has. If one takes the above-described case as a leg game, it cannot be determined whether the requirement 'les buyer comprises four or five pieces of the goods or whether

509843/0242

he mistakenly made an excessive amount of money in spite of the fact interjected that his real intention was to buy fewer pieces of the goods. As a result, the present Embodiment designed so that one to five pieces of the goods optionally supplied in the above-described case will.

The number of articles that the buyer actually wishes to purchase is determined when a! / Payment switch is pressed on a sales circuit, the structure and mode of operation of which is described in detail below ¹ .

The outputs of the sales signal generator VE _x , - VE are applied to the sales circuits for delivery of the number of articles selected by the buyer. Fig. 7 is a circuit diagram showing an example of the vending signal generator and the vending circuit. The sales _{signal generator VE 1} - VE _n have Roiaisspulen RYL ^ - RYL ^ '. The reference symbols RYL _x , - a ,, to RYL - a ,, denote relay contacts which are switched by the actuation of the relay coil RYL _x , - RYL. An alternating current source AG is connected to these relay contacts RYL ₁ - a ^ to RYL - a ,,. Selector switches 3W ₁ - xJW _n are provided accordingly for the sales _{signal heads VE x} , - VE to enable the buyer to choose a suitable

509843/0242

~ 42 -

to enable the desired number of articles. As a result, these selection switches GW _-1 - SW are present in a number which corresponds to the number of prices set in the sales price setting circuits SS _x , - SS. Motors M _x , - M are provided for the selector switches SW _x , - SW for delivering the desired article to the buyer. When one of the selector switches SW _x , - SW is pressed, the corresponding motor starts to deliver the desired number of items to the buyer. The drive of the motor is "stopped at the end of the delivery of the article. The switches SWM ₁ - 3WM are carrier or carrier switches, which are provided for the motors M. - M so that these motors run automatically for a predetermined number of revolutions. The reference symbols RI ^ - RL _n designate relay coils for self-holding and RL _x , -a ,, to RL -a ^ relay contacts that are switched by the relay coils RL _x , - RL. AC-DC converters AD _x . - AD are assigned to the motors accordingly. M _x , - M _{n connected in} parallel in order to apply a "0" signal to terminals Ad _x , - Ad.

Let it now be assumed that the relay coils RYL _x ] and RYI * 2 of the sell signal generator VuJ _x . and VEp are energized and the selector switch SWp is set. In this case, only the relay coil RLp is energized and only the contacts RLp - siy ,, RLp - ap and RLp - a, are closed.

509843/0242

As a result, the motor Mp is driven, so that the switch 3WIp is caused to change over from the position shown, whereby the coil EL ^ is de-excited. The pieces of the desired article are supplied by this driving movement of the motor Mp. When the motor Mp is stopped, the switch SWU is switched back to the position shown. In the meantime, the closing of the contact RLp-a ^ causes a signal "1" to be applied to the terminal IE via the AC-DC converter 70. This signal "1" reaches the memory 15 '(FIG. G) and is stored therein. A "0" signal is again supplied by the AC converter AD ~ to the terminal Ad ₂ .

Hit with reference to Fig. 6, the output from the operator 15 passes through the OR circuit 16 to the timer Tn in order to initiate a delay reaction of the timer Ta. After the 'Ver ^ ör'orungoaktion the timer Ta', the counter AJ is set to οj non for the subtraction prepared Zuntand in the same way as was previously described. D-3. The AND circuit 19 now receives the output of the inverter 17, the output of the AND circuit 19 becomes "0". Darrjunrin ν order the outputs of the AND circuits \ "<1 ^ to 12 _n " 0 ", and as a result the sales signals VE ^ -" V ^ "cease to generate sales signals

■, Π 9 8 A 3/0 2 4 2

The operation of the acceptance solenoid Ep is then the same, as previously described with reference to the first embodiment.

An output "1" from the AND circuit 21 becomes also given to one of the inputs of an AND circuit 65. The output of the AND circuit 65 is via the OR circuit 25 passed to the flip-flop circuit 26 and stored in this. This. Becomes in the self-holding state brought by their output through the AND circuit 27 and the OR circuit 25 is fed back to this upon application of a pulse DP. The output "1" of the flip-flop circuit 26 is also applied to a flip-flop circuit 28.

The output terminal of the flip-flop circuit 28 is connected to one of the input terminals of an AND circuit 30 an inverter 29 is connected. As a result, all inputs of the AND circuit 30 are "1" while the flip-flop circuit 26 generates an output "1" and the flip-flop switchxxng 28 has not yet received the pulse DP. The TFTD circuit 30 therefore produces a "1" output.

The output "1" of the AND circuit 30 is connected to AND circuits AP ^ - GP, - the subtraction pulse generator SP _x .,

509843/0242

SPp ... SP created. As a result, the signals from

the price setting circuits SS- - SS of OR circuits A1, - A generated by the timing by means of the pulses ty, - tj- shown in Fig. 4-. The outputs of the OR circuits A _-1 - A are assigned accordingly to AND circuits & 7a - 67, which are also the outputs of the AC / DC converter AD. - AD received from terminals Ad- - Ad via inverter 68 ,, - 68. The outputs of the AC-DC converters AD- - AD are also fed to a logic circuit 69 via the terminals Ad- - Ad and the inverters 68 ,, - 68. The logic 3 switch ^r xn <z 69 is designed so that it emits an output "1" when one of the outputs of the inverters 68 ^ - 68 is "1". The AC / DC converters AD- - AD provide an output "Ο" when the corresponding selector switches SW- - GW (JTig. 7) are set and the corresponding motors M- - M _ are driven. As a result, the signal "0" is applied to one of the terminals Ad- - Ad, which corresponds to one of the switches SW- - SW selected by the buyer p; e, whereby the AND condition of the AND circuit 65 is satisfied while the AND condition is also satisfied in one of the AND circuits 67 ^ - 67 _n , which corresponds to the terminal at which the "0" signal is present. An ^{OR circuit A- - A corresponding to this AND circuit X 1} Or generates an output which is sent to the OR circuit

5091 * 3 / 0-2 * 2

is applied via the corresponding one circuit of the IJNü-3chaltungen 67 ^ - 67 _n and further to the addition and ßuut rMkti selector AS via the OR circuit OH.

In this way, a value corresponding to the set price of the selected number of items is subtracted from the value stored in the counter A3. Since the interval ^ to the. the pulse t * of the pulse t, - occurs, is equal to the interval of the shift pulse ^ _x , is subtracted at every bit. If the set price matches the amount of coins inserted, all outputs P _x . - P ₁ - the corresponding stages of the register of the counter AS "0", whereby the entire circuit arrangement is reset by the reset circuit RG.

From the above it can be seen that the counted value of the addition and subtraction counter AS the Difference between the amount of coins wagered and the stipulated price will be. If this difference is not is, an amount of money corresponding to this difference is paid out as change. The change payment operation is performed in the same manner as previously described with reference to the first embodiment.

BATH ORIQIMAL 509843/0242

Next, a description will be given of an operation performed in a case where the exchange coin tube is short of exchange coins. If there is a shortage of change, a 10-yen shortage detection switch Sg is operated to apply a signal "0" to one of the inputs of each of the AND circuits 10 ^, 1O ₂ ... 1O _n through OR circuits 9 / j »9 ₂ ··· 9 _n ^{to be} delivered. As a result, when a shortage of change occurs, the AND circuits 12 ^, 12 ₂ ... 12 ^ connected to the outputs of the AND circuits 1Q ^, 1O ₂ ... 10 do not generate a "1" signal. Since the switch Sg is connected to an inverter 59 via the OR circuits 9 ^], 9 ₂ ... 9 ", its output is" 1 "and is applied to one of the inputs of an AND circuit 16. This receives a signal "1" from a memory 8 at its other input, so that the AND circuit 60 generates an output "1" which is supplied to a return memory 4-8 as a return instruction signal, '·'

As a result, if there is a shortage of change and a signal "1" is generated from the Yer- ■ - ¹ '-ί c ^ o circuit CM _{n of} the highest digit, the device is brought into a ti on - / repaired which is the same state v-'e in the ^ aIl is in which the return switch 3rd actuated vir; i., whereby i'ljo inserted coin or the inserted

!, 098 * 3/02 * 2

Coins are returned to the buyer.

While a coincidence signal is applied to the AND circuit 10 'through the OR circuit 9 _n , the MD circuit 10 continues to generate a "1" signal even when the 10 yen coin shortage detection switch Sg asserts an "O" signal the OR circuit 9 _n applies. In this way a sell signal is generated and the return operation described above is not performed.

As described above, this embodiment is extremely useful in a case where the buyer a plurality of pieces of the same item type desires, since the machine is able to dispense a desired number of the article within an amount of the thrown in Coins for sale.

The embodiment described with reference to Figs. 5-7 is formed so that a plurality of pieces one and the same article can be delivered. It will be noted that a plurality of types of articles are accepted by the machine of the same construction as described above can be supplied. To this end, the various Sales prices corresponding to articles in the price setting circuits SS ^ - So ^ in the form of binary information

09843/0242

preset, and the selector switches SW ^ - SW become set up to correspond to the articles concerned.

The one in the vending machine described above The addition and subtraction counter used consists of a plurality of flip-flop circuits. This type of counter has however, the tendency to malfunction when the power source is turned on, or when the automaton is on standby, i.e. when the coin has not yet been inserted into the slot and the counter has finished Counting operation has not started because the flip-flop circuits of the counter inadvertently reversed due to the noise that often occurs on such occasions became. The endeavor with regard to the incorrect operation of the dos addition and subtraction counters Vending machines are a very serious problem because the vending machines are usually along the street are set up and the meter is subject to the adverse effect of a very complicated noise. Even the addition and subtraction counter, which is controlled by a rakuimpuls, is a regular clock pulse not before the lapse of a certain time after the energy is generated into a very unstable State brought during this settling period. Of the

509843/0242

Counter is therefore likely to have an erroneous counting process perform if "for example a coin immediately is thrown in after switching on the energy source.

According to the invention, a reset control device is provided to prevent such an erroneous operation of the To prevent counter. Fig. 8 illustrates an example of such a rollback control device associated with the control system may be used, which is illustrated in Figures 1 and 2 and in Figures 5-7. Fig. 8 therefore shows the inner one Construction of a reset control device RCN as well as connections of the device with the coin return solenoid GA, the addition and subtraction counter A3, the pulse control unit PC and the shock or bounce prevention circuits 4, 5, 6.

In Fig. 8, the outputs of the shock or anti-bounce circuits 4, 5 and 6 are connected to respective ones Flip-flop circuits 74, 75 and 76 via NOR circuits 71, 72 and 73. The outputs of the flip-flops 74, 75 and 76 are connected to a flip-flop circuit 78 via a NOR circuit 83, an inverter 84 and a flip-flop circuit 77 given. The flip-flops 74-76 r: o are designed so that they are the result of the NOR circuits

509843/0242

71 - 73 temporarily save signal "1" and at. Apply the work pulse WP with a predetermined interval (Fig. 4-). The flip-flop circuits 77 and 78 also switch through a signal "1" stored in them in a timed manner when the working pulse WP is applied. The output of the flip-flop circuit 78 is applied to NAND circuits 80, 81 and 82 via an inverter 8.5. The NAND circuits 80-82 receive the outputs of the corresponding flip-flop circuits 74-, 75 and 76 at their other input terminals. The outputs of the NAND circuits 80, 81, 82 are connected to the flip-flop circuits 74-, 75 and 76 are applied via the NOR circuits 71, 72 and 73.

Thus, the signal "1" stored in the flip-flops 74- * 75 and 76 passes through the NAND circuits 80, 81 and 82 and becomes in the flip-flops 74-, 75 and 76 stored again for self-holding. When a signal "1" is generated from the flip-flop circuit 78, the condition of the NAND _r circuits 80, 81. and 82 is not satisfied, so that the flip-flop circuits 74-, 75 and 76. ,, get out of the self-holding state.

The flip-flop 68 produces a "1" output on the third word after the detection switches S ^ - S ^ are actuated to send a signal "0" to the NOR switch

50 9 843/024

dunking 71 - 73, i.e. when applying three pulses of the pulse WP, creating the self-sustaining state the flip-flop circuits 7 ^ »75 and 76 is canceled. These therefore provide an output "0" for the fourth word.

A reset signal generator RG ^ receives output signals from an energy switch-on reset _{control unit RG x} ,, a readiness identification control unit RGp and a readiness reset control unit RG-, via line

gen L ^ j, Lp or L ,. When any of the signals on the lines L ^ - Ti-, is "0", the output of the NAND circuit 102 becomes "1" and a signal "0" is output from an inverter 103 as a reset signal Rc. The addition and subtraction counter AS and the pulse control unit PC are reset by this signal "0". If all signals on the lines L ^ - L, are "1", the addition and subtraction counter AS and the pulse control unit PC are set to "1" by this signal. The "resetting" of the addition and subtraction counter AG means not performing the counting operation and maintaining the count amount a at zero without the possibility of malfunction due to noise, etc., while "setting" the counter means an operational state of the counter. The ar-

■ ti | » ,

beitsweise the corresponding control units RG ,. - RG, are described in detail below.

The power-on-reset control unit RG, supplies a signal "0" on the line L. during a Settling time from switching on the energy source until the start of oscillation of regular clock pulses, whereby the reset signal Rc 'is established during this time. In the example shown in the figure has the control unit RG ,. a CR time constant circuit 86 having a capacitor C,., which is connected to a negative power source -Vc is connected. The output of the time constant circuit 86 is fed to a MOS field effect transistor (hereinafter referred to as referred to as "MOS transistor") MOS. via inverter 87 and 88 created. The collector of the MOS transistor MOS ,, is connected to the input of an inverter 89. The gate of a MOS transistor, MOS, is connected to the output of the inverter 87, and at its collector

tor is the negative energy source -Yc. The emitter of the MOS transistor MOS is connected to the collector ^{1 of} the MOS transistor MOS ₂ . The working pulse WP is applied to the frat-t of the MOS transistor MOS ₂ . The emitter of the MOS transistor MOS ₂ is connected to the input of the inverter 89 and also ^ it a capacitor 90 which is grounded. In this way, the output of the inverter 89 passes through the

509843/0242

Line L ₁ to a NAND circuit 102.

The charging time for the CR time constant circle 86
is determined according to the time required for stable oscillation of the clock pulse. When the power source is switched on, the output of the
Time constant circuit 86 at a low level and
therefore forms the signal "0" during a certain period of time. As a result, the output of the inverter 84 becomes
a "1" signal and the output of the inverter 88 a "0" signal. This brings the MOS transistor MOS ^ in the conductive state, whereby the input side of the inverter 89 on
reaches a high level (ground potential) and a signal
"1" is applied to the inverter 89. In this way, a signal "0" is sent through the line L. to the NAFD circuit
102 passed, and the inverter 103 outputs a signal "0", whereby the addition and subtraction counter AS is reset. The "0" output of the inverter 89 is also given to a 'NOR circuit 97. The output of the NOR circuit 97 is provided to a coin return solenoid CA. The solenoid CA is operated upon receipt of a "1" signal from the NOR circuit 97 to return the inserted coin or coins to the buyer.

When the output of the time constant circuit 86 after

When the predetermined time becomes "1", the output of the inverter 87 becomes "0", whereby the MOS transistor, MOS, becomes conductive will. In the meantime, the work impulse WP, which is generated when the oscillation of the clock pulse stabilizes, applied to the gate of the MOS transistor MOS-, whereby this becomes conductive and the MOS transistor MOS. enters the non-conductive state. As a result, the Charge the capacitor 90. When the charge ends is, on the input side of the inverter 89 is a signal "0", and a signal "1" is via the line L ^ to the MITD circuit 102 is supplied. Therefore, the generation of the Reset signal Rc from the signals on the other lines Lp and L, from.

The standby identification control unit is arranged to supply a "0" signal to the HAND circuit 102 over the line Lp, thereby causing the NAND circuit 102 to display the reset signal Rc for a period of time from when the power source is turned on until it is detected the fact that none of the detection switches S., Sp and S, generates a signal "0"'as a result of • ^ crün error function and that the addition and subtraction counter AS does not carry out an incorrect count. The outputs of the inverter 84 and the flip-flop circuits · Ti ⁱⁿ nd 78 are fed to a NOR circuit 91 and via -one

509843/0242

Inverter 92 is given to a NOR circuit 93. The NOR circuit 93 also receives a count signal from the addition and subtraction counter AS via the line Lc. The counting signal is "0" when the count amount of the counter AS is zero, and is "1" when the count amount is another value than ITuIl is. The output of the TTOR circuit 93 is via an OR circuit 94- an AND circuit 95 is supplied. The AND circuit 95 receives the output of the inverter 89 and the pulse jzL shown in FIG. The .exit of the AND circuit 95 runs to one of the inputs of a UTTD circuit 96, the other input of which is the one shown in FIG BiIs ^ ρ receives. The output of the AND circuit 96 is connected to a NAND circuit via the line Lp 102 and also supplied to an OR circuit 94-. the Pulse / zL and ^ p are used in AND circuits 95 and 96 once applied to these AND circuits so that a "1" signal continues to be applied to them lies. The output of the AND circuit 96 is also led to a NOn switch 97. "

It is assumed that the oscillation of the clock pulse has been stabilized and that a signal “1” from the inverter P.9 is applied to the AND circuit 95. It is also assumed that the pulses φ ^ and φ _{2 are applied} to AND circuits T5 and 96, respectively. When one of the lock switches

S09843 / 0242

S. - S ^ does not operate properly and produces a "0" signal, the output of the NOR circuit 91 becomes "0" and a "1" signal is passed through the inverter 92 to the NOR circuit 93 · As a result, the AND Circuits 95 and 96 have an output "0", and the signal "0" is _{supplied to the NAND circuit 102 via the line L 2} , so that the reset signal Rc is generated. The same process as that described above takes place in a case in which the addition and subtraction counter AS counts incorrectly and a signal "1" is sent to the NOR circuit 93 via the line Lc.

When a coin is inserted in this state, V. it comes back to the buyer because the signal "0" passes from the UTTD circuit 96 to the NOR circuit 97, thereby actuating the coin return solenoid CA. If the counter AS does not perform a false count and the switches S. - S - do not work incorrectly, both signals applied to the NOR circuit 93 are "0". As a result, the AND circuits 95 and 96 produce an output "1", and a signal "1" is applied to the NAND circuit 102 via the line Lp- "■ ^r 1".-:!;. Thus, the generation of the reset signal Rc depends on the sirrial on line L-. The signal "1" of the ΤΤΓΌ-circuit 96 is also given to the OR circuit 94- to the signal "1" of the AND circuit 96 in a latching

509643/0242

to keep the state. As a result, the oirmal remains
"1" on the line Lp, once the ready state is confirmed after holding the switch, too
constant when the switches 3 - S, are actuated and the counter A3 performs a counting process.

The standby reset control unit Rj _{2 is designed so that it continuously supplies a signal "0" via the line L 7} to the HAND circuit 102 when no coin is inserted and a series of addition and subtraction counting operations are not carried out, so that
which produces the return signal Hc, and that the TTAITD circuit 102, if one of the switches S-S is operated, ceases to generate the reset signal Rc and is thereafter prevented from generating the reset signal Rc
until a series of counting operations is completed.

The TiAITD-ochaltnn ^ 99 receives the output of the inverter. ^{p /} (- 'in'] also the off fan rc of the flip-flop circuit
77, which is carried out via the inverter 9B ζ-ige. The output of the IT'LHD-ochaltmig 99 comes through a NOR circuit ••: i ο ine flip-flop-Schol-tunn; 79. The input signal of the
Flip-flop circuit 79 is temporarily stored therein and then sampled when the pulse DP shown in FIG. 4 is applied. The sampled signal is transmitted via the

509843/0242

Lei tune; I /, supplied to the NAND circuit 102 and to the NAND circuit 101. The NAND circuit 101 also receives the count signal from the addition and subtraction counter AS via the Lei tun g Lc and an error signal via the Lei tune LE. The error signal is when the Zählbetrarr a reversible counter (not shown) "0" of the addition and "jubtrakti ons counter A3 by subtracting a negative ^T confused comb! IMD otherwise" 1 ". It is believed dal? Oimale" 1 "ran over the lines L ^ and Lp to the NAND- • 3chqlt-mT 102 and no coin was inserted into the machine. The output of the inverter 84 is" 0 ", and the output of the 3rd inverter 9β is" 1 " output of the ITA-ITD Schaltuiv:?. 99 therefore ir.t a 3ignal "1", and the issue ran <~ the Lioi - ^r Jchaltung 100 is a signal "0" As a result, supplies the flip-flop circuit 79. a signal "0" via the line L ₇ to the NAND circuit 102, whereby the reset signal Rc is generated. Thus, the addition and subtraction counter A3 is constantly reset.

If a coin is inserted and the "jchnlter · Χ is confused, the flip-flop circuit generates"'' ■ <- in signal "1" when a first working pulse WP is applied to it - "This signal "1" is given via the inverter τη to the ITAITD circuit 99. Since the output of the Flipn-77 is "0" at this time , the

509843/0242 BAD ORIOWAL

NAND circuit sends a signal "1" to the flip-flop circuit 79 via the NOR circuit 100. The flip-flop circuit produces a signal "1" upon receipt of the pulse DP, so that the output of the the inverter 105 connected to the NAND circuit becomes "1", whereby the generation of the reset signal Rc stops. The AS counter is now set and ready for operation. The amount of coins inserted is now calculated and the signals on lines Lq and L · ™ become "1". Since the output of the flip-flop circuit 79 is a signal "1", supplies the NAND-ochaltunp; 101 to the NOR circuit 100 a signal "0". The flip-flop circuit 79 therefore receives a signal "1", whereby the signal "1" on the line L ₇ . is made self-retaining. If the counting signal on the line Lp becomes "0" when the operation of the counter AS for subtracting the price from the stored amount has ended, the NAND condition of the NAND circuit 101 is no longer met, so that the flip-flop circuit 79 outputs an output "0", which in turn generates the reset signal Rc.

It can be seen from the foregoing that the reset control device can effectively prevent the addition and subtraction counter AS from malfunctioning due to external noise by

that an accurate resetting of the counter in the standby state is guaranteed.

The reset control device can also prevent the counter AS from failing in generation regular pulses works incorrectly, namely by the fact that the counter AS is reset and one Coin inserted during the settling when the energy source is switched on until the oscillation begins a regular clock pulse is returned. In this way, the buyer is faced with an unexpected Loss of his coin protected-.

There are several in a vending machine Types of coins inserted, and if two or more types of coins the hold-open switches at the same time as a result of a delay in the passage of the previous coin or when the coin is inserted of the coins have pressed '"in very rapid succession, a wrong count occurs, i.e. the correct amount of inserted coins is not calculated. According to the invention is a false count prevention device; envisaged, -um prevent the occurrence of such a wrong count. O'ig. 9 illustrates an example of the misdial preventing device; located between the locking switches S. - S, and the pulse control unit PC is located.

In Fig. 9, the vibration or Bounce prevention circuits 4, 5 and 6 detection signals when inserting different types of coins.

Store flip-flop circuits 107, 108 and 109 temporarily a signal "1" which has been supplied by their respective OR circuits 104, 105 "and 106, respectively, and emit the signal "1" upon receipt of the working pulse WP of a predetermined pulse interval. The exits the flip-flop circuits 107, 108 and 109 are connected to flip-flop circuits via AND circuits 110, 111 and 112, respectively 113, 114 and 115 respectively. The output terminals of the flip-flops 113, 114 and 115 are through an OR circuit 116 connected to a flip-flop circuit 117. The flip-flops 113 and 114, 115 and 117 are obtained also the work impulse WP.

The outputs of the flip-flop circuits 113, 114 and 115 are connected to AND circuits via inverters 118, 119 and 120, respectively 121, 122 or 123 as well as on IWD circuits 124, 125 "or 126. The AND circuits 121, 1? 2 and 123 also receive the hangings of the flip-flop circuit o.il 107, 108 and 109, respectively. As a result, that is temporarily stored in a ^ n flip-flop circuits 107, 108 and 109 Signal "1" held by itself that it is in it

stored again via the -AND circuits 121, 122 and 123, respectively will. This latching state is canceled when the signal "1" from the flip-flop circuits 113r 114- and 115 is delivered.

The AND circuits 124, 125 and 126 also receive the output of the flip-flop circuit 117 via an inverter 127. The WID circuits 124, 125 and 126 correspond to the respective ones used in the vending machine Coin types. The outputs of AND circuits 124, 125 and 126 are sent to the counter (not shown) as coin detection signals created to add the nominal values of the inserted coins.

The output of the flip-flop circuit 117 arrives via a NOR circuit 129 to the AND circuits 110, 111 and 112. The output of OR circuit 116 runs

to the NOR circuit 129 and also to the AND circuit 128.

The AND circuit 110, 111 and 112 also receive the outputs of the inverters 4, 5 and 6 via inverter 130, 131 and 132. In addition, the AND circuit 111 is the output of the flip-flop circuit 107 ^ via an inverter-13 ^ fed.

509843/0242 ₀

The AND circuit 112 also receives the output of a NOR circuit 134, to which the outputs of the flip-flop circuits 107 and 108 are given.

The outputs of the flip-flop circuits 107, 108 and 109 and the output of an inverter 135 connected to the output terminal of the NOR circuit 129 are supplied to the coin return solenoid CA via an OR circuit 136. The solenoid CA is used to insert the pin into the coin passage «?; dos pickup A to move in and pull out of it. When a "1" signal is applied to the solenoid CA, it is de-energized so that the pin protrudes into the coin passage <τ. A coin subsequently inserted into the slot is blocked by the pin and delivered to the coin return outlet OUT.

As a result, if one of the flip-flop circuits 107-109 generates a "1" signal, the inserted coin is rejected, thereby preventing successive insertion of coins which is likely to cause the counter to be incorrectly counted. External] em is used for '' O ¹ H in the event that a signal "0" arises as a result of incomplete contact of one of the salaries S. - S-, an inserted coin by applying a signal "1" to the solenoid CA of the corresponding der Flip-flops 107-109 ejected.

The operation of the anti-counting device will be described with reference to a case where the switches S., Sp and S ^ have been operated simultaneously are.

The use detection signals "O" from the switches Sy, Sp and 3, respectively, are reversed by the inverters 4-6, and the outputs "1" of the inverters 4-6, which go through the OR circuits 104- _ 106, are stored in the flip-flop sheets 107-109. The stored signal "1" is read one word later (eg example 1 ms) when the pulse WP is applied. The read signal "1" is given to the AND circuits 110, 111 and 112 and to the AND circuits 121, 122 and 123. Since the outputs of the flip-flop circuits 113, 114 and 115 are "0" in this stage, the AND conditions of the u ¥ D 3 circuits 110, 111 and 112 are met, so that these AND o circuits are self-sustaining State. In the meantime, the AND circuits 110, 111 and 112 receive an output "1" of the NQR circuit 129. The AND circuit 111 also receives a signal "0" from (1 - ^r .i inverter 133 »and the AND -Circuit 112 receives a signal "0" from the NOR circuit 134- If the switches 3 ^, S ₂ urrl S are operated in this state, the outputs of the inverters 130, 131 and 132 become "1", and these

509 & 43/0242 bad orioinal

Outputs "1" are fed to AND gates 110, 111 and 112. The AND circuit 110 therefore supplies the Flip-flop circuit 113 gives a signal "1". The signal "1" is one word later (two words when counting from the beginning an) read and after passing through the OR circuit 116 in the flip-flop circuit 117 stored. The signal "1" from the flip-flop circuit 113 is also sent to the inverter 118 is applied, and the output "0" of the inverter is fed to the AND circuit 121. This will make the The latched state of the flip-flop circuit 107 is canceled. The output "1" of the flip-flop circuit 113 becomes also fed to the AND circuit 124-. Since the output of the AND circuit 128 is "1" at this time, AND circuit 124 generates a 100 yen coin detection signal.

The "1" signal stored in the flip-flop circuit 117 becomes one word later (three words when counting from the beginning), so that the output of the AND circuits 128 and 124 becomes "0". The output of the flip-flop circuit 117 becomes "0" one word later (four words counting from the beginning), so that the NOR circuit 129 produces an output "1".

When the output of the NOR circuit 129 has become "1", the AND circuit 111 supplies the already one

509843/0242

Signal "1" received from the inverter 133, an output "1". This output "1" is stored in the flip-flop circuit 114 and read off one word later (five words "counting from the beginning). This output signal" 1 "is used to maintain the latched state of the flip-flop circuit 108 and cause the AND circuit 125 to generate a 50-yen coin detection signal In the meantime, the output "1" of the flip-flop circuit 114 is stored in the flip-flop circuit 117 after passing through the OR circuit , whereupon the Ausp-an ?; the "OR circuit 116" becomes "0" and the MD condition of the AND circuit 111 is no longer fulfilled. The flip-flop circuit 117 generates a "1" signal one word later (six words counting from the beginning) so that the outputs of the AND circuits 128 and 125 become "0". One word later (seven words counting from the beginning), the output of the flip-flop circuit 117 becomes "0", so that the output of the NOR circuit 129 ^{becomes "1 M} ".

When the output of the NOR circuit 129 has become "1", the AND circuit 112 provides an output "1", since η or · output of the NOR circuit 134 has already become "1". The output "1" of the AND circuit 112 is in the flip-flop - '''Chaltunp; 115 and read off one word later (eight words counting from the beginning). This exit

509843/0242

"1" cancels the self-holding]! State of the flip-flop circuit 109 and causes the AND circuit 126 to generate a 10 yen coin detection signal. To this Wise become the 100, 50 and 10 yen coin detection signals with a suitable time interval therebetween.

From the above description it can be seen that in the event that two or more switches within one Word time are actuated, a detection signal first for a coin with higher priority and for a coin with lower priority is only established after the coin with higher priority has been detected by the flip-flop circuit 117 is detected (i.e., the flip-flop 117 has generated a signal "1").

As a result, when these coin detection signals to count the amount of inserted coins are delivered to the counter, no two or more detection signals produced at the same time, so that incorrect counting of the counter is completely avoided wi i'd.

It should be noted that when a switch is operated for a coin of lower priority, for example S ₇ ,, more than

5 0984 3/0242

one word time before pressing a switch for one Coin with higher. Priority, e.g. S., the determination operation of switch S, for a coin with a lower "priority the detection operation of the switch S. for a Precedes a coin with a higher priority.

In the above description, "the terms" higher precedence "or" lower precedence "do not mean the face value of the coins, but a hierarchy in the generation of the detection signals. In the present embodiment, the detection signals are ranked a 100 yen coin, a 50 yen coin, and a 10 yen coin generated when the three switches are operated simultaneously. However, the ranking can be changed if necessary without the performance of the anti-counting device to reduce.

The following is a preferred example of the coin control device: described according to the invention.

Fig. 10 is a front view of the coin control device: to illustrate the passage of the inserted coin. The device comprises a transducer A, which is designed to hold a plurality of coins (100 yen coins, 50 yen coins and 10 yen coins in the

509843/0242

present example), allows the rejected coins to flow to their respective outlets as they are inserted and, when the device is in the "reject state", allows all inserted coins to flow to a return outlet, and a coin control mechanism B which includes a mechanism to to insert the 10 yen and 50 yen coins sorted out by the pick-up A. under the coins into a 10 yen coin tube or into a 50 yen coin tube, and, if the coin tube is full, the inserted coin into a coin box, a mechanism for temporarily retaining a 100 yen coin according to a mechanical principle, a mechanism for returning the temporarily retained 100 yen coin to a return position, and for inserting the retained 100 yen coin into the coin box in an accept position and a mechanism for paying out of change from the corresponding coin tubes.

In the return position, the inserted 50-yen coin runs from a path I ^ down on a path I ₇ to an outlet 140 of the receiver A. The 10-yen coin passes from a path I ₂ down on a path l _o to the outlet 140. the 100 yen coin passes in the same way from a Bahn 1, - down on a web Iq to the outlet 140. These coins will then to a main return path

509843/0242

of the coin control mechanism B and returned from an outlet OUT. In the acceptance position, the 50-yen coin runs through lanes I ^ and Ip to an outlet Ί 39 - the 10-yen coin moves up. Lanes I ₇ , and I ^ to outlet 137. The 100 yen coin passes lanes I ₁ - and I ^ to outlet 138. These coins are then directed to coin control mechanism B. The relative arrangement of the outlets 137, 138 and 139 is shown in Fig. 10 (b).

In the coin control mechanism B, the 10-yen coin is received in a 10-yen coin tube Gp or, when the fine tube Cp is completely filled with 10-yen coins, into the coin box via a path 1 ^^. introduced. The 50 yen coin is received in a 50 yen coin tube CL or, if the coin tube Cp is never full, fed into the coin container via a path 1 ^, ^. -The 100 yen coin runs through a path Ι ,, ρ to a position G, where it is temporarily retained by means of a retention mechanism described later. The TOO yen coin is then fed to the main return path 141 via a path 1 ^ ₁ - in the return state or to the coin container via a path I ^, _.

The pick-up A comprises -a coin return device, • .v. ^ Lche the inserted coin in a sales stop state, by interrupting the. electrical energy supply

or caused by the sale of items for sale is to weave back by energizing the coin return solonoid CA. can. A preferred example of such a coin return device will now be described.

With reference to Jig. 11 and 12, one end of a return lever 143 is pivotally supported on a bearing lug 147 which is attached to the rear surface of the receiver A. This return lever 143 is provided with interrupting pins 150a, 150b and 150c, which are arranged so that they _{can interrupt the paths 1 ^, 1. and I 1} - of the pickup A in the return position. The receiver A is provided with openings 149a, 149b and 149c to receive the pins 150a, 150b and 150c. An adjustment screw 152 is attached to the rear surface of the receiver A. This adjusting screw 152 extends through the return lever 143. A coil spring 15I surrounds the adjustment screw 152 between the return lever 143 and the rear surface of the receiver A.

One on a main body 142 of the vending machine Fixed return solenoid CA has a movable iron piece 145 on which an operating lever 146 of the return lever 143 is firmly attached. When the movable iron piece 145 is not attracted to the solenoid CA, i.e.,

50 9 8 43/0242

when the solenoid CA is not energized, the operating lever pushes 146 the return lever 143 by the force of a spring 153 into a position in which the interrupting pins

150a - 150c can interrupt the passage of the coins. At the end parts of the lever 143 and the movable iron piece 145 there are stops 154 and 148, respectively.

Now the operation of the coin return device described.

When the sales process is due to cessation of supply has been interrupted by .electric energy or as a result of the item being sold out, the solenoid GA de-energized, so that the movable iron piece 145 falls off. The movable iron piece 145 is driven by the solenoid CA as a result the force of the spring 153 rotated away, whereby the actuating lever 146 is caused to the return lever 143 in. A

To move position in which the interruption pins 150a

- 150c run through the openings 149a - 1'49c of the pickup A and thereby - interrupt the coin paths 1, I _x , and 1-. As a result, the movement of the inserted coin is interrupted by one of the pins 150a-150c depending on the denomination of the coin, as shown in Fig. 12, so that the coin does not go to the outlet 137 »138 and 13.9, respectively

509843/0242

(Fig. 10) but is diverted to the return outlet 140 (Fig. 10).

'When the sales process is initiated, this will be Solenoid CA energizes and attracts the movable piece of iron. This causes the return lever 143 to oppose each other clockwise as shown in Figure 11, causing the breaker pins 150a-150c pulled out of the pickup A. Thus, the inserted coin can run to the coin acceptance path.

If the pickup A is removed from the main part 142 of the vending machine and reattached to it becomes, the adjusting screw 152 provided on the pickup A becomes in accordance with the pressing force of the operating lever 146 set.

The coin return device described above is very simple in construction because it is essentially consists of break pins formed in one piece with the return lever and an electromagnet which di.ο;? en return lever actuated. It also generates this Device no vibration during its actuation because the return lever is driven by the actuating lever, which is in front of the movable iron piece of the electromagnet

is seen. In addition, the device is advantageous in that than the return lever is attached to the receiver in one piece, so that no adjustment of the interrupting pins is required when the transducer is attached to the vending machine.

The structure and operation of the other parts of the receiver A, with the exception of the coin return device, are known, so that their description could not be used.

The coin control mechanism B will now be described.

Fig. 15 is a perspective view of the coin control mechanism B with certain parts broken away and shown in section to show underlying constructional details. The main return path 14-1 is formed by side parts 155a and 155c of a housing 155 and a partial bottom part 155b., A change payout device described later is housed in a space made up of low side panels 156, 157 and a bottom panel I58 is limited. The 10-yen-IhHiZfJiI-tube C ^ and the 50-yen-coin-tube G. are attached at their lower end part to the base plate 158 and (.! • extend downward through the base plate 158) in one piece with it the bottom plate-158 is an inclined

Plate 170 formed, which rises obliquely from its end adjacent to an outlet 159. A frame 160 for supporting the electromagnetic solenoids E 1 and E 1 is also attached to the bottom plate 158. The solenoids E _x . and Ep are attached to a horizontal frame part 160a of the frame. A plunger 161 of the oolenoid Ep is connected to an acceptance lever PL ,,. When the solenoid is de-energized, the plunger 161 protrudes and causes the lever PL ^ to protrude through an opening formed in a 100 yen coin guide portion 162 to a position in which the foremost end portion of the lever PL ,, against the inner surface of a 10 yen and 50 yen coin guide plate 163 butts. Although not shown in the figure, the plunger of the solenoid E. is also connected to a return lever PLp (Figs. 10 and 1A-), and the return lever PLo is in a position in which its foremost end part is against the inner surface of the guide plate 163 bumps.

A proximity switch S- is provided above the receiving end of the 10-yen coin tube Cp to detect the passage of an inserted 10-yen coin. Dear switch S, is generally U-shaped with an Aucsparunc S, _& to allow the 10-yen coin to pass through. As a result, the inserted e falls through the coin tube Cp, the recess S,

of the proximity switch S, and is stacked in the coin tube Cp. The 50 yen coin also falls' into the coin tube Gy, through a recess Sp of a proximity switch S ^,

When one of the coin tubes Cp and Gy. is filled with a predetermined number of coins, the inserted coin \ which has passed through the correspondingly assigned proximity switch S and Sp is not received in the coin tube. As from Fig. 16 (a) and ITig. 16 (b), a coin blocking device SX.

Similarly, a coin blocking device SX ₂ comprising a pin Pp, a weight Wp, a release lever BLp and a coin-driven lever Kp is disposed above the 50-yen coin tube C * . '· "

If there is no stack of coins or the stack of coins is relatively small, the coin runs on the inside of the coin tube C ~ not on the coin-driven lever Ky .. The blocking _{device SX x} . is therefore in the open position, in which it is rotated clockwise (based on B ¹ Ip: 16) as a result of the weight W., the
