<p>PURPOSE:To eliminate vibration of a tape drawing pin and to stabilize high speed running, by fixing a drawing means of a magnetic tape, in a device capable of applying a small-sized cassette to a large size magnetic tape device. CONSTITUTION:When an operation knob 57 is slied right with an operation arm 53 kept opne, a tape 4 in a smal-sized cassette 2 is drawn on its way with tape drawing pins 15 and 27. In turning the arm 53 counterclockwise so as to close an operation opening 58, a slide lever 39 is slided toward the arrow 60 and a fixed lever 31 is slided toward the arrow 61. Thus, a pressing part 31a depresses the pin 15 with a tensile spring 32 and is clipped with a positioning block 62 fixed to a case 1 of a large size cassette adaptor and a pressing part 31a, allowing to fix the position of the pin 15. This is applied to the same as the other pin 27.</p> |
