<p>PURPOSE:To improve operating feeling contact of a cassette holder and to reduce an overstroke by constituting to draw the holder downward by the arm of a locking mechanism in holding of the cassette. CONSTITUTION:A cassette holder 11 is engaged to be held in contact through locking arm 14 of a locking mechanism and a pin 14a, and the holder 11 and a cassette are placed only by gravity on installing positions at this time. Then, the arm 14 is drawn down by a predetermined driving mechanism, and the holder 11 presses the cassette to the position by the drawing force. A leaf spring 12 is fixed to the holder to be drawn by the arm 14, and the spring 12 is brought into contact with the arm 14. When the holder 11 is drawn at a predetermined amount, the spring 12 is deflected to absorb the drawing amount under the arm 14. Thus, an overstroke is reduced to improve an operating feeling contact.</p> |
