Electronic device mounting apparatus

摘要

An electronic device mounting apparatus prevents an error at the setup time prior to startup of the apparatus and enables mounting of proper electronic devices without a mistake. A cartridge and a lane of a cartridge mounting rack have a cartridge side connector (upper electrode portion, connection plug, lower electrode portion) and a lane side connector (fixed plug) which are electrically connected when the cartridge is installed on the lane. An error detecting circuit is formed by employing these connectors as part thereof. The error detecting circuit determines whether or not the installation position of the cartridge is appropriate depending on the conductive state or non-conductive state from a power supply to a warning buzzer when the connectors are connected.
