Claims (1)

[Claims for Utility Model Registration] (1) An autoloading mechanism that sets the tape cassette at the playing position by inserting the tape cassette, an auto-ejecting mechanism that ejects the tape cassette at the playing position, and each of these mechanisms. A sound reproducing device comprising: a drive motor for driving a magnetic head; a gear transmission mechanism interposed between the drive motor and each of the mechanisms; and a magnetic head control mechanism for controlling forward and backward movement of the magnetic head. A power disconnection lever is provided in the transmission path of the gear transmission mechanism to bring the meshed gears into or out of mesh. A sound reproduction device characterized by a non-meshing state between the spaces. (2) An autoloading mechanism that sets the tape cassette at the playing position by inserting the tape cassette, an auto-ejecting mechanism that ejects the tape cassette at the playing position, a drive motor that drives each of these mechanisms, and In a sound reproducing device comprising a gear transmission mechanism interposed between a drive motor and each of the mechanisms, and a magnetic head control mechanism for controlling forward and backward movement of the magnetic head, the gear transmission mechanism may , has a power disconnection lever that brings the meshed gears into mesh or out of mesh, and the power disconnection lever is operated in conjunction with the operation of the magnetic head control mechanism, and the power disconnection lever is operated in conjunction with the operation of the magnetic head control mechanism. 1. A sound reproducing device comprising a holding means for maintaining the meshed state when the head is in a paper ejecting position when the dewing mechanism is operated.
