Abstract
An electronic apparatus is provided that can eliminate unlawful cartridges while preventing a malfunction by checking whether there is a short-circuit of pin terminals at the time of turning on the power source and conducting further improved security checks. The electronic apparatus has an electronic apparatus body 2 and a cartridge 5 to be detachably mounted to the electronic apparatus body 2. The cartridge 5 is equipped with a connector having a plurality of terminals and is connected to the electronic apparatus body 2 via the connector. The electronic apparatus body 2 outputs a first and a second short-circuit detecting signal for conducting a short-circuit detection of a circuit portion connected via the plurality of terminals. The cartridge 5 receives the first short-circuit detecting signal and the second short-circuit detecting signal via the plurality of terminals and determines whether the circuit portion is short-circuited or not based on the received first and second short-circuit detecting signals.
