Claims (1)

[Scope of Claim for Utility Model Registration] A carrier movably supported between a tape cassette insertion/removal position and a tape cassette retraction position, and a pair of tape reels wound with magnetic tape housed in a cassette case. At the same time, a sliding plate that opens and closes an insertion hole for inserting a reel shaft that engages with the tape reel formed on the bottom of the cassette case, and a front side where the magnetic tape is pulled out to the outside of the cassette case can be freely opened and closed. The conveying body holds a tape cassette with a front cover and is movable up and down between a raised position where the tape cassette can be transferred and a lowered position where the tape cassette can be installed in a cassette mounting position. a cassette holder supported by the cassette holder and provided with a locking means for locking the sliding plate; a cam gear having a cam groove on one main surface and rotationally driven by a drive motor; a slider member that is moved by the rotation of the slider member, and a cam lever that engages the cam follower with the cam groove and is rotated by the rotation of the cam gear in the same direction as the moving direction of the carrier. a cassette retracting member movement operation plate; a cassette retraction member movement operation plate that extends over the tape cassette held on the cassette holder when the conveyance body is pulled into the tape cassette retraction position; The tape cassette is supported rotatably in a direction perpendicular to the direction, and a cassette engaging portion is provided at the distal end to engage with the back side of the tape cassette that has reached the tape cassette retracting position, and a cassette engaging portion is provided at the proximal end to engage with the back side of the tape cassette that has reached the tape cassette retracting position. A cassette retracting member is provided with a rotated operation part that abuts and engages with the provided rotation operation part, and the cassette engaging part is biased to rotate in a direction in which the cassette engaging part is separated from the cassette holder by a biasing means. The cassette retracting member has a rotatable operating portion that is rotatably operated by a rotary operating portion provided on the slider member by movement of the slider member after the carrier reaches the retracting position. The cassette retracting member is rotated against the biasing force of the biasing means so that the cassette engaging portion engages with the back side of the tape cassette, and the cassette retracting member is moved by the rotation of the cam gear. By moving the tape cassette together with the operation plate in the retracting direction, the cassette case is moved relative to the sliding plate that is locked to the locking means of the cassette holder, and the reel shaft is inserted through the cassette case. A tape cassette mounting device with an open hole.
