<p>PURPOSE:To prevent the misinsertion of plural kinds of cassettes whose size is different, and to exactly insert a cassette into a cassette holder, by providing a cassette detecting means on a guide body having a guide groove for guiding the insertion of plural cassettes. CONSTITUTION:A guide body 3 provided with a groove which is a little wider than the width of a cassette is provided on the cassette insertion port of a device, and an insertion control member for detecting whether the position of the cassette and its insertion attitude are normal or not, and obstructing an insertion to a cassette holder 18, when they are abnormal is provided. Accordingly, a normal insertion can be executed in an early stage and the work efficiency is improved. Also, since a groove which coincides roughly with width of the cassette, even a worker who has no knowledge at all regarding the device can discriminate easily the inserting position, and the operability is improved. By only engaging the cassette to the groove of the guide body 3, the inserting position can be positioned with the high accuracy, and the workability is improved.</p> |
