<p>PURPOSE:To prevent the disconnection of a wiring wire rod of a sensor when a cassette holder has reciprocating motions by omitting said wiring wire laid between a chassis and a cassette holder. CONSTITUTION:A cassette detecting means consists of a lever 15 to be detected and a sensor 23 which is set at the side of a chassis 1. Thus the wiring wire rod of the sensor 23 so far laid between a cassette holder 2 and the chassis 1 can be omitted unlike a conventional cassette loading device containing the sensor 23 set at the side of the holder 2. thus it is possible to evade such a case where the wiring wire rod of the sensor 23 laid between the holder 2 and the chassis 1 catches other parts of the chassis device and disconnected or worn when the holder 2 has reciprocating motions In such a way, impossibility of detection of the kind of cassette 50 being in a loaded or unloaded state to the holder 2 are prevented due to the disconnection of the wiring wire rod of the sensor 23.</p> |
