PURPOSE:To attain ease of operation and a small sized device by providing a projection opening a shutter to a cassette guide and a lever closing the shutter. CONSTITUTION:When a cassette 68 is inserted to a cassette guide 67 while a shutter 85 is closed, the tip of a projection 87a of a switching lever 87 contacts an end ridge of the shutter 85 and the tip of the projection 87a overrides the side face of the shutter 85. In pressing further the cassette 68, the end ridge of the shutter 85 contacts a projection 91, then the projection 87a of the switching lever 87 is fitted in the shutter 85 via the opening 85a and in pressing the cassette 68 further, since the shutter 85 is blocked to the position by the projection 91, the shutter 85 is opened. On the other hand, in closing the shutter 85, when the cassette 68 starts being ejected from the state when the cassette 68 is loaded, since the ridge of the opening 85a of the shutter 85 contacts an upright wall 87d of the projection 87a of the switching lever 87, the shutter 85 stays as the position and only the cassette 68 is moved in the ejecting direction. |
