Filed: 1985-06-27
Abstract: PURPOSE:To display the number of stored coils with a simple constitution by detecting the number of coils stored in a cashbox in each denomination and storing it in a storage device and displaying stored information with a key or dial operation. CONSTITUTION:When coins are stored in the cashbox, a coin detector 11 outputs the detection signal of the number and the denomination of them to a controller 16, and the controller 16 adds this information to a value in a prescribed area of a stored information storage device 15 and stores the result there again. When a money collector confirms stored information, he operates a key switch 12 to depress a dial key corresponding to information to be confirmed. This dial number is detected by a dial number detector 13 to designate the corresponding area of the storage device 15. The controller 16 reads out information in the designated area and displays it on a remainder service display device 14. Thus, the number of stored coins is displayed easily.
