<p>PROBLEM TO BE SOLVED: To eliminate confirmation made by opening a door body and to make it possible to recognize whether or not a tape cassette has been loaded on a loading part at a glance from the outside, by protruding a detection member from the outer surface of the door body when the loading part having the tape cassette loaded is closed by the door body. SOLUTION: When a tape cassette 3 is loaded on a loading part 4, the read side surface of the tape cassette 3 comes into contact with a positioning projection 8 to contact a projection 9, and a front surface is elastically pressed by a press spring 27 and positioned. A holding piece 31 is positioned in the relief recessed part 4b of the loading part 4, the rear side surface part of the protruded part 7a of the rear side surface of the tape cassette 3 is positioned in the recessed part 4a and a reel base 11 is engaged with the tape reel of the tape cassette 3. Thus, the upper end of the tape cassette 3 is moved to the front of a holding part 14 against the resisting force of the press spring 27, the pressed part 37 of a detection member 15 contacted with the protruded part 7a of the front side is pressed forward, a pressed part 34 is guided to a guiding projection 25 against the resisting force of a leaf spring part 35 and the tip part of a protruded part 36 is protruded forward from a sliding hole 19.</p> |
