Claims

[Scope of utility model registration request]

a head chassis including a magnetic head and slidably disposed between a first position in which the magnetic head advances to bring the magnetic head into contact with the magnetic tape and a second position in which the magnetic head retreats from the magnetic tape; Left and right reel stands, a drive gear that is rotatably arranged between the reel stands and has a small diameter gear in the center and a large diameter gear on the inner surface of the outer periphery, and is controlled in conjunction with the operation of the head chassis. a transmission gear rotatably disposed at the free end of the operating lever and selectively meshing with a large diameter gear or a small diameter gear of the drive gear depending on the sliding position of the head chassis; A tape recorder comprising: a pair of planetary gears that are disposed in constant mesh with a gear, and that move in the rotational direction of the transmission gear and mesh with the reel stand or reel stand rotation gear located in the moving direction. When the head chassis is advanced to the first position, the transmission gear is engaged with the small diameter gear of the drive gear by the operating lever and rotated at a low speed, and the transmission gear is rotated at a low speed according to the direction of rotation of the transmission gear. The reel is moved to the reel stand side and driven at a low speed in the playback mode, and when the head chassis is retracted to the second position, the transmission gear is moved to the large diameter gear of the drive gear by the operating lever. A drive transmission mechanism for a tape recorder, the drive transmission mechanism for a tape recorder being configured to be meshed with the planetary gear and rotated at high speed, move the planetary gear to a reel stand side corresponding to the rotational direction of the planetary gear, and drive the planetary gear at high speed at a rotational speed in a high-speed transfer mode.
