A device is provided for counting and sorting coins of various sizes. The coins are supplied from a container for unsorted coins to a guide channel adjacent thereto for guiding the coins individually and successively. The guide channel has a continouus reference edge and a base provided with openings which correspond in size to the sizes of the types of coin. A counter detects coins in the guide channel without contact. Spring loaded levers and/or conveyor belts or the like are provided for mechanically urging the coins against the reference edge.

Device for counting and sorting coins

A medal counting apparatus installed in a game parlor for counting medals which a game player has won is disclosed. The medal counting apparatus comprises a counter (100) for counting the medals, a medal supplying mechanism (200) for receiving the medals to be dumped and for supplying them sequentially to the counter (100), a dump restraining unit (300) for restraining the medals from being dumped into the medal supplying mechanism (200) and a control unit (400) for controlling operations of the medal supplying mechanism (200) and the dump restraining unit (300). The control unit (400) puts the medal supplying mechanism (200) into a stopped state when the dump restraining unit (300) restrains the medals from being dumped and into an operation state when the dump restraining unit (300) permits dumping of the medals. The control unit (400) also instructs the dump restraining unit (300) to close the receiving hopper (210) when a medal dump restraining signal is input from the outside or the counter (100) has not been used for a certain period of time. When there is a request to dump medals, the control unit (400) then instructs the dump restraining unit (300) to open the receiving hopper (210).

An electrical circuit arrangement for use in a coin counting device is provided. The arrangement is provided with an abnormality detection circuit for generating an alarm signal when any of the optical sensing member of the coin counting device is hindered from operating normally due to adhesion of dust or other causes. The abnormality detection circuit includes a NAND gate, a NOR gate, an OR gate, a counter and an SR-type flip-flop. The first and second detection signal generated from the optical sensing members are supplied to the NAND gate and the NOR gate. The OR gate is supplied with the output from the NOR gate and a reset signal from a reset operator section. The counter is supplied with the output from the NAND gate and the output from the OR gate. In normal operation, the counter counts the level "1" and "0" of the binary logical level alternately, thereby to leave a counting section to continue the counting operation. If any abnormality occurs at any of the combined optical sensing members, the number counted by said counter takes the value 2, whereupon a second output signal indicating the occurrence of abnormality is generated by the counter and fed to the flip-flop which generates an alarm signal.

Counting circuit for coin counting device

Mechanism is activated by coins, with coins inserted through an opening that connects to two outlets. The first connects to a coin return point, while the second connects to a coin collection chamber. The mechanism comprises a test mechanism that tests if coins are transferring correctly from inlet to either of the two outlet points and detects a blockage if one exists. If a blockage is detected a user can be alerted so that money is not entered when the machine is not working.

Coin operated machine, especially a phone box, has a mechanism for testing the correct transfer of coins between insertion and collection or return, so that a user is alerted if a blockage occurs, thus preventing fraudulent use

Errors in coin processor counting or denominational value determining attributable to foreign matter present on the processor guide rail or to surface defects in coins are detected and indicated by use of a counter incremented and decremented in accordance with output signals successively generated by sensors examining coins in transit.
