PURPOSE:To improve the dustproof property and the operability by providing reel shaft inserting holes in a case and a sliding body, and closing inserting holes of the case with the sliding body when a device is not used, and sliding the sliding body to allow its inserting holes and inserting holes of the case to coincide with each other when the device is used. CONSTITUTION:A sliding body 3 is stored in a cassette case 2 slidably in the direction of an arrow X1. The case 2 consists of a case body 2A and a cover body 2B which can open and close the case body 2A and closes normally the aperture in the front of the case body 2A. When the device is not used. the sliding body 3 is slided in the direction of an arrow X2 and is stored completely in the case boyd 2A, and a nothced part 10 is closed by the bottom plate of the case body 2A. Reel shaft fitting holes 17a and 17b of the case body 2A and reel shaft fitting holes 18a and 18b of a substrate 4 are shifted from each other completely, and holes 17a and 17b are closed by the substrate 4. In the cource of setting, the cover body 2B is turned at about 90 deg. with respect to a shaft 2Bb and is opened, and the sliding body 3 is slided in the direction of the arrow X1 in accordance with this opening and is pulled out partially from the case body 2A, and the notched part 10 is exposed, and holes 18a and 18b coincide with holes 17a and 17b.
