<p>PURPOSE:To press-contact assuredly a pinch roll to a capstan, by fixing an aluminum die cast support block to a chassis and sliding a metallic parts which supports the pinch roll with guidance of the support block. CONSTITUTION:A pinch roll 57 which holds horizontally a rotary shaft above a tape guide path and shunts before loading is held horizontally by prescribing the positional relation between a hanging metallic parts 61 and a pulling metallic parts 63 for a holding metallic parts 59. When a pulling shaft 70 is moved back, the parts 63 pulls rotary arms 62 and 62 and turns the parts 59. Thus the roll 57 is set opposite to a capstan 58. Then the arms 62 pull the parts 59 when the shaft 70 moves back further. Thus the lower part of the roll 57 touches first the capstan 58, and the whole part of the roll 57 is press-contacted to the capstan 58.</p> |
