Abstract
A power supply control circuit controls power supply to a circuit when an external unit is connected to and/or disconnected from a terminal unit to which the circuit is coupled. The power supply control circuit includes a first sensor for detecting whether or not the external unit is in a first state where the external unit is close to the terminal unit, a second sensor for detecting whether or not external unit which has been already connected to the terminal unit is in a second state, and a control circuit for controlling the power supply to the circuit in accordance with detecting results obtained by the first and second sensors. In addition the above power supply control circuit is applied to a computer game machine having a main circuit coupled to a cartridge slot to which a cartridge is to be connected.
