<p>PURPOSE:To prevent a device from being damaged by forming tape cassette positioning faces vertical to the formation face of a tape cassette guiding grooves of the tape cassette on the upper face of the aperture parts of the guide grooves. CONSTITUTION:When the tape cassette 1 is inserted into a cassette holder 37, a pair of tape cassette guiding projection parts 39 guide the cassette 1 while engaging with a pair of tape cassette guiding grooves 34 of the cassette 1 to insert the cassette 1. When a pair of tape cassette front face positioning projections 38 are abutted upon a pair of tape cassette front face positioning faces 36, the cassette 1 is positioned in the holder 37. Since the projections 38 and the projected parts 39 are unitedly formed, positioning strength can easily be improved. Thereby, even when the cassette 1 is inserted into the holder 37 by strong force, the projections 38 are not deformed and the cassette 1 can not be entered into the device. Thus, the device can be prevented from being damaged.</p> |
