<p>PURPOSE:To always easily load a cassette tape at a correct position, by providing a cassette tape detecting means at a cassette tape holding part. CONSTITUTION:A movable contact piece 4b in a cassette holding part 4 is brought into contact with the upper end of the side plane of a cassette tape 8 in a state that the cassette tape 8 is loaded at a cassette tape loading part 2, and presses and holds the upper end. And according to being pressed, the movable contact piece 4b is pressed to the outside (leftside in figure) by the cassette tape 8, and is brought into contact with the head end part 4a1 of a fixed contact piece 4a, and a switch consisting of the fixed contact piece 4a, and the movable contact piece 4b as a detecting means to detect the presence/ absence of the cassette tape, is turned on, thereby, the loading of the cassette tape 8 can be detected. In such way, it is possible to appropriately load the cassette tape preventing a pressing force exceeding a required level from being applied on a loaded cassette tape.</p> |
