Abstract: This bill accepting device comprises a bill discrimination section for discriminating whether an inserted bill is true or not, an escrow section capable of retaining a bill accepted by the bill discrimination section as a true bill and returning the retained bill, a stocker section for storing the bill accepted by the bill discrimination section as a true bill, and passage switching means for causing a bill passage in the bill discrimination section to communicate selectively either with the escrow section or with the stocker section. The passage switching section normally communicates the bill discrimination section with the escrow section to enable an inserted bill to be retained in the escrow section in a state in which the bill can be readily returned. When the escrow section has become full, the passage is switched so that the inserted bill is guided from the bill discrimination section to the stocker section.

Abstract: This bill accepting device comprises a bill discrimination section for discriminating whether an inserted bill is true or not, an escrow section capable of retaining a bill accepted by the bill discrimination section as a true bill and returning the retained bill and a stocker section provided between the bill discrimination section and the escrow section, including a bill conveying passage connecting the bill discrimination section and the escrow section and receiving a bill being present in the bill conveying passage in a predetermined accumulating location by moving the bill in a direction in which the bill crosses the bill conveying passage. The inserted bill is led to a linear passage in the stocker section through the bill discrimination section.

Abstract: A bill retention device includes a relatively long guide belt which has one end thereof secured to a first rotary member and the other end to a second rotary member and is wound on the first rotary member when no bill isretained at all. For accommodating bills, the second rotary member is rotated to wind the guide belt and also wind the bills tightly thereon. In accordance with winding of the second rotary member, the guide belt is unwound from the first rotary member. Thus, the guide belt is finally wound on the second rotary member many times resulting in winding up of a large number of bills. By having the guide belt wound on the first rotary member simultaneously with the reverse rotation of the second rotary member, the retained bills are unwound from the second rotary member one by one whereby the bills can be automatically returned.

Abstract: A stored coin and bill number counter unit counts up the numbers of deposited coins and bills for respective denominations and counts down the numbers of paid out coins and bills for the respective denominations and thereby obtains the numbers of coins and bills for the respective denominations stored for paying out of change. A comparison and operation unit primarily judges whether vending is possible or not by comparing the amount of the deposited coins and bills with the set vend price and obtains the amount to be paid out as change by calculating difference between the deposited amount and the set vend price.

Abstract: An up-down counter of a vending machine performs upcounting and downcounting in accordance with deposition and pay-out of coins and collection of a vend price, thereby producing a balance of an amount of deposited coins. The count of this up-down counter is indicated by a money amount indicator. A total sales summing device introduces, through a connector, money amount indication data provided from the up-down counter to the money amount indicator and performs a sales amount summing processing in accordance with this money amount indication data. This summing device detects the increment and decrement of the money amount indication data, performs upcounting and downcounting in response to this increment and decrement and prohibits downcounting of the decrement in the money amount indication data when the decrement has been caused by collection of the vend price. By virtue of the count prohibition control the difference between the amount of the deposited coins and the paid out coins, i.e.

Abstract: A coin selection device is of a type in which reference voltage is automatically adjusted in accordance with variation in the output level of a receiving coil in a standby mode. A oscillating coil and a receiving coil are disposed on both sides of a coin path. A peak of output level of the receiving coil and the reference voltage are compared each other in a comparator for detecting whether inserted coin is true or false. The output level of the receiving coil in the standby mode is stored so that variations in temperature and circuit parameters can be taken into account in the reference voltage level.

Abstract: A vending machine is generally equipped with a money amount indicator which indicates an amount of deposited coins or a balance thereof. This total sales indication device utilizes the money amount indicator to indicate a total sales of the vending machine on this indicator when the vending machine is not making a vending operation. Prices of articles sold are cumulatively added by a sales counter to obtain a total sales and counting contents of this sales counter are indicated on the money amount indicator by manipulating an indication control switch.

Abstract: A vending control system for sequentially carrying out a first and second operation in order to insure that the selected article is in fact vendible and that the correct amount of change is provided. During the first operation, the amount of deposited coins is compared with the vend price of all articles in order to determine which articles are vendible, and article selection switches corresponding to the vendible articles are enabled. And during the second operation, the amount of deposited coins is compared with the vend price of an article selected by operation of the corresponding article selection switch, in order to confirm that the selected article is in fact vendible and to insure that the proper amount of change is provided.

Abstract: A coin dispensing apparatus capable of selectively dispensing a coin of a predetermined denomination from among coins of various denominations stored in a coin tube assembly.

A coin level detector is disposed in the housing so that the detector can be set in position when the tube assembly is attached to the housing. The detector detects when the number of coins is reduced to a predetermined value.

Abstract: A coin changer comprises a coin changer main part and an electronic type coin discrimination device which can be readily mounted to and detached from the coin changer main part. The electronic type coin discrimination device includes a detection coil for detecting characteristics of a deposited coin, a discrimination circuit for judging whether the deposited coin is a true coin or a counterfeit one in response to the output of the detection coil and produces a sole kind of discrimination signal representative of trueness or falsity of the coin regardless of the denomination of the coin, a true coin passage and a counterfeit coin passage provided behind the detection coil and a mechanical coin sort-out device provided in the true coin passage for sorting out coins by denomination.

Abstract: In a coin counting device for an automatic vending machine, the outputs of counters adapted to counts the number of inserted coins separately according to the denominations of the coins are multiplied by the factors which are set by setting circuits separately according to the denominations, respectively, to obtain the total amount of money of the inserted coins. The factors can be changed according to the denominations of coins to be handled by the automatic vending machine, without modifying the circuitry, so that the device can handle coins of any denominations.

Abstract: In the malfunction indication device for a vending machine according to this invention, a malfunction occurrence indicator is provided at a prominent place on the outside of the vending machine. This indicator indicates occurrence of malfunction immediately upon detection of the malfunction by a malfunction detector to give warning to a purchaser. Simultaneously, a code representing a detected malfunctioning point is stored in a memory circuit. By manipulation of an indication control switch by an operator, the code representing the malfunctioning point is read from this memory circuit and indicated by a malfunction code indicator. As the malfunction occurrence indicator and the malfunction code indicator, a money amount indicator already provided in the vending machine for indicating an amount of deposited coins or a balance thereof is advantageously utilized.
