<p>PURPOSE:To reduce the sucking force of the solenoid which sets the tape under the running state of reproduction and others by decreasing the distance between the capstan and the pinch roller via the lever which interlocks racking of the cassette tape. CONSTITUTION:With push of the reproduction and record buttons, reel 23 has one turn. And the racking component shifts along the guide groove and via the wire which is to be taken up to reel 23, and thus the tape is racked to the cylinder. At the same time, slide 71 shifts via coupling pin 70 unified with reel 23, and lever 74 has coupled turns. As a result, the distance is decreased between pinch roller 17 and capstan 18 via link levers 80, 81 and 91 which are coupled to the plunger of solenoid 77. Accordingly, the sucking force can be reduced substantially for solenoid 77 which gives pressure to capstan 18 to roller 17 in order to make run the tape at the reproduction time and others.</p> |
