<p>PURPOSE:To keep a reproduced state just by a short-time operation of a reproduction button for a tape ecorder which is set in a reproduction state with the revolving force of a motor, by keeping a power supply switch on with a mechanical trigger carried out when the reproduction button is operated. CONSTITUTION:When a reproduction button 5 is pushed light, a reproduction lever 2 slides toward an arrow A. Then an interlocking bar 6 hits a hook bar 12, and therefore an action lever 8 turns counterlockwise round the center of a pin 9. Then an interlocking recess part 13 is set free from a pin 17 on a slide base 16 and therefore moves toward an arrow B by the force of a spring 11. A a result, an end of the lever 8 pushes a contact bar 15 to turn on a power supply switch 14. Thus a motor starts its revolution, and the base 16 slides toward an arrow C and locked to keep a reproduction state. In this case, the pin 17 is set at the part 13. When a stop button is pushed, the lock of the base 16 is released. Then the base 16 slides toward the arrow C by the force of a spring 19. At the same time, both pin 17 and lever 8 slide to return to their original positions respectively.</p> |
