PURPOSE:To attain not to set the cassette to insertion state unless a cassette is loaded correctly, by providing detecting arms on both sides in the inner part of a cassette holder and operating detecting arms with the end face in the leading side of insertion of the cassette when the cassette is inserted. CONSTITUTION:When a cassette 3 is inserted normally, an escape groove 3a of the cassette 3 can permit a projection 601 of a cassette holder 4 to pass through, and detecting parts 501b of detecting arms 501 are pressed by the front end face of the cassette 3 through a notched part 3b of a front door 3c of the cassette 3, and detecting arms 501 in both sides are turned, and detaining parts 501a become higher than stopping bodies 801, which are formed by bending side brackets 51 in both sides, not to stop the movement of a cassette holder 4, and thus, the cassette holder 4 can be inserted to a cassette insertion detection position. |
