Claims

[Scope of utility model registration request]

A card-shaped memory insertion device for inserting and removing a card-shaped memory into and from a microcomputer system main body includes a voltage detection circuit for detecting a voltage of a pull-up resistor connected between input terminals of the card-shaped memory, and an output of the voltage detection circuit. a latch circuit that holds the state; a CPU that determines that the card-shaped memory is inserted into the microcomputer system main body based on the output of the voltage detection circuit that is held by the latch circuit; and a determination from the CPU. A card-shaped memory insertion device comprising: a power supply switching circuit that switches the power supply to the card-shaped memory based on a signal.
