Claims

[Scope of Claim for Utility Model Registration] In a switch control mechanism for canceling idler neutrality that neutralizes the idler in a state before tape loading, a. A tape loading gear that performs a tape loading operation. b A switch pressing part provided on a part of the tape loading gear. c A control switch that is operated by being pressed by a switch pressing part when the tape loading gear moves slightly forward. d. A control unit that reverses the tape loading gear and moves it in the backward direction when the idler neutral release command is issued in response to the operation of the control switch. e When the tape loading gear moves forward, the idler is pressed in a direction different from the idler neutral release direction by the switch pressing part, and when the tape loading gear moves backward, the idler performs the idler neutral release operation by being pressed in the idler neutral release direction by the switch pressing part. Neutral release member. An idler neutral release switch control mechanism characterized by having each of the constituent requirements a to e above.
