Electronic register

Abstract

Abstract PURPOSE: To prevent burglary surely by opening a drawer by an exchange key operation only when a code number stored in a memory previously agrees with a code number inputted by a casher. CONSTITUTION: When a casher who knows exchange number "123" stored previously in the exchange number memory in RAM 40 operates ten-key "123" and exchange key "exchange", "123" is inputted to the N register, and "1" is inputted to NFM, and exchange number "123" is read out from the exchange number memory, which is provided in RAM 40, to the X register after confirming entry "1" of NFM and the exchange number by the continuous exchange key operation, and the entry number of the X register is subtracted from the entry number of the N register to input their difference to accumulator B. Next, in case that the entry number of accumulator B is 0, an open signal is sent from CPU 33 to I/O port 44 to excite solenoid 28 of drawer open device 31, thereby opening drawer 2.
