<p>PURPOSE:To make a cassette position detecting mechanism small in size by providing a detecting metallic parts to a cassette holder and a detecting means for said detecting metallic tape to the inner side wall of a loading mechanism respectively and detecitng the vertical and horizontal positions of the cassette holder by one of the detecting means. CONSTITUTION:A cassette position detecting mechanism contains a projected detecting metallic parts 8 attached at the tip of a cassette holder 2. Then a detecting means 9 for the parts 8 is set on an inner side wall 10 at the left end position of the loading mechanism 1. The mechanism 1 contains the holder 2 hanged by a rail 3, and a cassette 4 is put into the holder 2 from the direction of an arrow head A in a state I shown in the figure. Then the holder 2 moves horizontally up to a state II. Here it is detected that the parts 8 is set at the left end position. Then the horizontal shift of the cassette 4 is stopped and the cassette 4 is moved vertically in a state III. When the cassette 4 is shifted to the state II from the state III, the vertical shift of the cassette 4 is stopped to set the cassette in the state I after detecting that the parts 8 is set at the upper limit position. Thus the cassette 4 is moved horizontally. In such a way, the miniaturization is possible with the cassette position detecting mechanism.</p> |
