<p>PURPOSE:To attain the music program searching in a simple structure by providing a music program searching lever on a substrate rotatably around, a vertical axial line to the substrate and hooking a hook part of said lever to a projection of a head stage in a program searching mode and then releasing this hooking in an ejection mode. CONSTITUTION:When a cassette loading action is over, a head stage 12 moves down. Then a pin 182 slides the side surface of a hook part 181. When the pin 182 gets out of the part 181, a lever 180 is turned counterclockwise by a spring 185. A play mode is set when the stage 12 is moved down further. When a music program searching action is carried out in a play mode, the pin 182 hits the part 181 to limit the move-up action of the stage 12. Then an ejection lever 20 is pushed to press the edge of the lever 180 to the left side. Then the lever 180 is turned clockwise round the axial line of the spring 185 to move up the stage 12. Thus the hook between the lever 180 and the pin 182 is released owing to the revolution of the lever 180.</p> |
