ABSTRACT:
A tape running device of a video cassette recorder. This device comprises a capstan shaft, an arm pinch having both a tape guider and a rotatable pinch roller, a holder provided under the arm pinch in order to elevate, lower and rotate the arm pinch, a gear pinch engaging with the holder for guiding the elevating and lowering motion of the holder, a guide plate engaging with the holder for causing the holder to be vertically elevated and lowered, a take-up arm rotatably mounted on the main plate and having a shaft for pulling the tape out of a tape cassette, and a connection gear gearing into both the gear pinch and the take-up arm in order to transmit the rotational force of a drive motor to them and rotating the holder in order to rotate the arm pinch toward the capstan shaft. The tape is run under the condition that its nonmagnetic surface is wrapped about both the tape guider and the pinch roller. The tape in a FF/REW mode is run under the condition that it is separated from all the pinch roller, the tape guider and the capstan shaft but guided by the shaft of the take-up arm.
