Claims

[Scope of utility model registration request]

a pole base that pulls out the tape from inside the cassette; a ring that is connected in a double-acting manner by the pole base, slide lever, and SPR and is driven by a loading motor to move the pole base to a predetermined position;
A first shifter cam is rotated by being given a rotational force by this L ring, a second shifter cam has a constant reduction ratio with respect to this first shifter cam, and is driven by both the first shifter cam and the second shifter cam. The tension arm, FF/REW gear, and F synchronize with the movement of the pole base.
It has a cam that moves the F/REW auxiliary brake, loading brake, etc., and is fixed at a fixed position by the second shifter cam until halfway through loading, and after being slid by the cam part of the second shifter cam halfway through, it is moved by the first shifter cam at least. A mechanism drive device for a video tape recorder, characterized by comprising a shifter that slides one step.
