Claims

[Scope of utility model registration request]

An auto-stop mechanism in a video tape recorder that does not rotate a rotating drum when the tape running mode is a fast forward mode or a rewind mode, and the mechanism includes a brake member that is arranged to be able to come into contact with and separate from the brake drum of a reel stand, and that drives the rotating drum. a pressing piece rotated by a driving means for pressing the brake; a first position connected to the brake member to bring the brake member into contact with the brake drum; The second
and a third position in which the rake member is moved in the brake release direction and one end thereof is not located on the rotation trajectory of the pressing piece; The first slider has a resilient means that always resiliently biases the slider toward the first position, and a retaining part that is removably engaged with an engaging part formed on the first slider.
a first position in which the slider is located when the slider is in the first position and a first position in fast forward mode and rewind mode.
a second slider that is moved between a second position that causes the slider to move to the second position and a third position that causes the first slider to move to the third position in recording mode and playback mode; and moving means for moving the second stone slider to first, second, and third predetermined positions according to a predetermined tape running mode, and at least the second slider , such that when the third position table is moved, the movement of the first slider by the resilient means is prevented by the engagement of the engaging portion of the first slider with the engaging portion of the second slider. At the same time, automatic stopping from the recording mode and playback mode is performed by moving the second slider to the first position by the moving means, and automatic stopping from the fast forward mode and rewinding mode is performed by the driving means. is driven so that the first slider is moved by the pressing piece to the second slider.
The first slider is moved to the first position by the elastic force of the elastic means, and the second slider is moved to the first position by the moving means. 1. An auto-stop mechanism for a video tape recorder, characterized in that an engaging portion of a first slider is engaged with the engaging portion of the auto-stop mechanism.
