<p>PURPOSE: To provide a device capable of solving misdetection and of correctly detecting by means of a leaf spring made of magnetic body and flexed by mounting a cassette on a mounting part, of a sensor detecting the cassette by flexing of the leaf spring and of attaching a magnet attracting the leaf spring to an opposite direction of flexing by mounting the cassette. CONSTITUTION: A mounting part 1 is fitted with a leaf spring 2 made of magnetic body and flexed by mounting a cassette 5, a sensor 3 detecting the cassette 5 by flexing of the leaf spring 2 and a magnet 6 attracting the leaf spring 2 in an opposite direction of flexing by mounting the cassette. It is fitted with for example the leaf spring 2 made of iron, material containing iron or so on and flexed via a block 4 made of Teflon by mounting the cassette 5, the photosensor 3 detecting the cassette 5 by interrupting light caused by flexing of the leaf spring 2 and the magnet 6 such as a permanent magnet or an electric magnet, etc. These can remove vibration by the leaf spring and prevent error detection of a cassette.</p> |
