Claims

[Claims for Utility Model Registration] (1) A cassette body in which a magnetic tape is housed so as to be partially exposed to the outside, and a cassette body on which the cassette body is mounted and which can cover said portion of the magnetic tape from below. a cassette having a lower lid that can be slid along the main body, and an upper lid that can be opened and closed to cover the portion of the tape from above and from the front; A detecting member capable of angular displacement around an axis perpendicular to the direction, the detecting member having an abutting portion that protrudes from below into the cassette insertion path and abuts the cassette; The present invention is characterized by comprising a switch whose switching mode changes accordingly, a spring which biases the detection member in a direction in which the abutting portion protrudes into the insertion path, and means for fixing the lower lid body when inserting the cassette. Magnetic tape cassette insertion detection device. (2) The magnetic tape cassette insertion detection according to claim 1, wherein the length of the contact portion of the detection member is selected to be larger than the moving distance of the lower lid body. Device.
