An electric circuit device includes a connector for permitting removal and mounting of a cartridge with a circuit built therein, and a processor for performing operations and processing using the circuit built in the cartridge. A first reset circuit is provided in the electric circuit device for supplying the processor with a first reset signal, and for producing the first reset signal when resetting is commanded by manual input or when a power supply to the electric circuit device is turned on. The electric circuit device also includes an arrangement for producing a connection detection signal indicating whether or not a cartridge is mounted to the connector, and a second reset circuit for receiving the connection detection signal via the connector. When the connection detection signal is not received by the second reset circuit, it outputs a second reset signal. When the connection detection signal begins to be received, the second reset circuit terminates the second reset signal a predetermined time after tile beginning of the reception of the connection detection signal. The processor is reset when it receives either the first reset signal or the second reset signal.
