Claims

[Scope of Claim for Utility Model Registration] A rotating plate that is rotatably attached within a plane including the top surface of the casing and connected to a drive mechanism for rotation, and a rotating plate that is attached to one end of the rotating plate. a slide hook that is attached to the slide hook and has a retractable claw that engages with a recess formed in the upper part of the cassette that is inserted into the cassette holder provided in the housing when the cassette is retracted; a retraction detection switch for detecting a retraction completion state in the cassette holder; attached to the slide hook;
The present invention is characterized by comprising an operating member that operates the retraction detection switch at the retraction completion position and maintains this operating state for a period of time until the drive mechanism starts moving the rotary plate in the opposite direction. A cassette retraction state holding detection device for a magnetic recording/reproducing device.
