<p>PURPOSE:To form a simple mechanism with one plunger, by absorbing and releasing one holding plunger plate with one plunger, and interlocking each lock plate for a head plate and a pinch roller plate. CONSTITUTION:On a holding plunger plate 22 pivotally engaged 23 with a tape player base B, a lock plate 28 for a head plate 1 and a lock plate 33 for pinch roller plate 2 are provided. To both lock plates 28 and 33, a control pin 8 for the head plate 1 and a control pin 19 for the pinch roller plate 2 are latched in a prescribed time difference, and at the 1st release of absorption of the plunger 25, the head plate 1 is set to the position of program search and the pinch roller plate 2 is to the back position, and at the 2nd release of absorption, the plates 1 and 2 are both moved to the back position. Thus, the one holding plunger 25 can control the head plate 1 to three stages, allowing to simplify the entire mechanism.</p> |
