O Utility Model Registration Claims A drive gear driven by a motor, an assist gear that meshes with the drive gear and transmits driving force, a head substrate that is moved forward by the assist gear, the drive gear and the assist gear. , a solenoid that controls the engagement with the head board, a regulation plate that stops the head board at a cue/review position slightly before the playback position, and a regulation plate that controls the position of the regulation plate based on the difference in power supply time to the solenoid. A tape recorder comprising a control means.

Claims

[Scope of utility model registration request]

A motor that is driven by the operation of the operation button that sets the mode, an assist gear that is driven by this motor, a restriction part formed on this assist gear, and a first pin that is removably exposed to this restriction part. a trigger arm that rotates the trigger arm, a solenoid that rotates the trigger arm, a toothless portion that releases rotation of the assist gear at a position where the restriction portion and the first pin are engaged, and a first portion that biases the assist gear to rotate. A biasing member, an eccentric cam provided coaxially with the assist gear, an assist lever in which a second pin faces the eccentric cam in a slidable manner, and is slid via a spring by rotation of the assist lever. a head substrate having a head, a select arm rotatably provided on the assist lever, and a first engaging portion in which the select arm is engaged and disengaged by the trigger arm when the solenoid is turned on and off. A play lever that is slidably provided together; a second biasing member that biases the select arm toward the first retaining portion; and a second biasing member that biases the select arm toward the play lever. , a play rotation transmission means of a motor that is switched by a cam surface provided on the play bar to drive the reel, and is engaged with the select arm when the select arm and the first retaining portion are not engaged. a control lever that is rotatably provided and has a second retaining portion; a rotation transmission means for fast forwarding and early return of the motor that drives the reel by the control lever; and a third control lever that is provided on the head substrate. an engaging portion, a switching lever that is switched between two positions: fast forward, early spring return, sit cue, and review; an operating lever that operates this switching lever; and an operating lever that is provided on the switching lever so that the switching lever is in the fast forward/early spring return position. When the third engaging part of the helad board comes into contact with the tape loaded on the reel, the red contacts the first contact part located at the non-sliding position with the tape loaded on the reel, and the switching lever 1. - a second degree in which the third retaining portion of the head substrate abuts when the switching lever is in the cue/review position to position the head in a sliding contact position with the tape loaded on the reel; first and second contact portions provided on the play lever and the switching lever, respectively, for retracting the first and second contact portions out of the sliding range of the third engaging portion when the play lever is actuated; A tape recorder comprising a switching section.
