<p>PURPOSE:To prevent the generation of the collision sound and vibration of a slide substrate in stop motion, by changing operation modes by using an operating gear having a toothed part and untoothed part at its circumference and a pinion engaging with it. CONSTITUTION:Operating gear 8 having untoothed part 11a and toothed part 12a and pinion 13 engaging with it and driven by motor 25 are provided. Further, three-armed lever 6, and transmission lever 19, etc., are provided. In this constitution, three-armed lever 6 is disengaged by pulling lever 2 back with the power supply to solenoid 1 out off in play mode to rotate operating gear 8 counterclockwise by the return force of lever 19 and then pinion 13 engages with gear 8. At this time, motor 25 drives to rotate lever 8 counterclockwise, so that lever 19 and slide substrate 21 will return to their stop position by spring 23. At this point in time, pinion 13 disengages from gear 8 to set the stop mode. Consequently, the engagement between pinion 13 and gear 8 provides braking force and the collision sound and vibration of slide substrate 21 can be prevented.</p> |
