Claims

[Scope of utility model registration request]

a reciprocating lever driver having an idle gear drive cam section provided at a predetermined position; one end slidably locked to the idle gear drive cam section and the other end bendably connected to the second drive lever; A first drive lever that rotates as the lever drive body moves, and an idle gear that can be engaged with left and right reel gears, respectively, are rotatably supported at predetermined positions.
A second drive lever rotated by a drive lever, left and right reel gears arranged at a predetermined interval, and left and right flywheel gears arranged at a predetermined interval. When transmitting the rotational driving force of the gear to one of the reel gears via the idle gear, the idle gear is moved by the rotation of the first drive lever and the second drive lever, and the rotating flywheel gear is first transferred to the rotating flywheel gear. A cassette type tape recorder characterized in that an idle gear is engaged with and rotated, and by continuous driving, the idle gear is engaged with a reel gear and the reel gear is rotated.
