<p>PURPOSE:To stabilize running of a tape, by constituting so that by interlocking a pinch roll with a pinch lever supporting a pinch roller freely rotatably, in accordance with a fixed speed running in the forward direction and the backward direction of the tape, and detaching by a tape guide of a downstream side of the tape is detached. CONSTITUTION:On both sides of a head rotating mechanism 9a of a head chassis 3, tape guides 51, 52 are provided. The tape guides 51, 52 are inserted through grooved parts 511, 521, and its lower parts are supported by guide levers 513, 523 freely turnably. The guide levers 513, 523 are axially supported by pins 514, 524, the other end parts project in the almost L-shape, and arm parts 515, 525 are fitted to shaft 5a, 6a of a pinch roller. When a tape is reproduced in the forward direction, the head chassis 3 and the tale guides 51, 52 move in the upper direction in the figure, turning of a pinch lever 48 is controlled on the way, the guide lever 513 is totated counter-clockwise, and the tape guide 51 is pushed upward and contacts with a tape 53. The tape guide 52 of the downstream side stops its movement on the way, and does not brought into contact with the tape 53. In this way, running of the tape is stabilized.</p> |
