Title: Detecting device for connection of memory unit
Inventor: HIRAI TOSHIYUKI
IPC: G06F3/00
Filed: 1987-05-12
Abstract: PURPOSE:To prevent the breakage of data as well as the runaway of a program although a card is mistakenly inserted in or taken out of a card reader, by writing the data into a specific address of the card to confirm the presence or absence of the card and also checking periodically the data to discontinue the execution of other processes until the coincidence is secured with the initial state of the data in case the data has a change from its initial state. CONSTITUTION:When the pulses are supplied to a CPU 4 from a timer 9, the CPU 4 reads the data 1c out of a memory card 1. At the same time, the data 1c of the card 1 is latched by a latch circuit 5. Then the pulses are periodically supplied to the CPU 4 from the timer 9. Thus the CPU 4 compares the data read out of the card 1 with the latched contents of the circuit 5. If it is known from said comparison that the card received from the card 1 has a change, the CPU 4 discontinue the execution of other processes until the data contents are coincident with its initial state. Thus it is possible to prevent the breakage of data as well as the runaway of a program.
