<p>PURPOSE:To eliminate an exclusive spring which protrudes a cassette, by holding the cassette in a cassette housing room due to an elastic deformation of a lock lever which is caused by pressing the cassette receiving part with the cassette when a cassette is loaded. CONSTITUTION:A lock lever 22 of an elastic material which has a lock hooking part 25 at one end and a cassette receiving part 26 at the other end is provided in a cassette housing room 16 into which a cassette 1 is loaded. When the cassette is loaded, the part 26 is pressed by the cassette 1. Thus the lever 22 has an elastic deformation. As a result, the part 25 is hooked to a recess part 13 formed at a cassette 1, and this cassette 1 is held in the room 16. The figure shows a state under which the cassette 1 is loaded until it reaches the part 26 of the lever 22.</p> |
