<p>PURPOSE:To realize a thin and light-weight structure for a magnetic recorder and reproducer as a whole, by controlling the inclination of a tape guide by means of the right and left edges of a tape guide provided on a plane parallel to a mobile sliding surface and also close to the sliding surface plus a projected bar for control of position. CONSTITUTION:When a tape guide body 25 of the inlet side slides on a subchassis 17 along a guide groove 23 and toward an arrow C, a magnetic tape is wound round a roller 25a and a slanting guide 25b. A driving pin 25e transmits the loading driving force to the guide body 25 and at the same time engages the groove 23 and a width control U-shaped groove 26c to perform the positioning of the guide body 25 in directions of arrows J and K. The shift of the guide body 25 toward C is stopped by the contact between a slope 25c and a projecting part 26a. The rotary motion within a plane (arrows L and M) right-angled to the direction C is prevented by the contact between a sliding surface 25d and a reference surface 26b. The elevating direction (arrows N and O) is controlled by an elevation control surface 26d. Furthermore, the up-down movement is controlled by a pressure-contact surface between the slope 25c and the projecting part 26a.</p> |
