<p>PURPOSE:To improve operability in the loading of a second cassette by moving a supporting part having a contact coming into contact with the contact of an adaptor in the up-and-down direction corresponding to the up-and-down movement of the adaptor, and surely making both contacts bring into contact. CONSTITUTION:The contact is formed on the side plane of the adaptor 30, and the contact 8 coming into contact with the contact of the adaptor 30 is formed at the supporting pat 20, and the upper and lower planes of the adaptor 30 are abutted on a guide piece 21 formed at the upper and lower sides of the supporting part 20 when it is drawn in and out from the cassette insertion port 3 of a main body. The supporting part 20 is also moved in the up-and-down direction corresponding to the up-and-down movement of the adaptor 30 when it is drawn in and out. As a result, the contact of the adaptor 30 can be surely brought into contact with the contact 8 of the supporting part 20. Therefore, it is possible to distinguish a first cassette from the adaptor 30 based on the contact state of the contact 8, and to stop the adaptor at a position where the second cassette is loaded/unloaded. In such a way, the operability in the loading of the second cassette can be improved.</p> |
