<p>PURPOSE:To save electric power consumption and to prevent the generation of a shock noise by allowing a cam gear to start rotating at its nontooth part only by pressing a bevel provided to the cam gear through a lever, and engaging it with a flywheel gear when operating the cam gear for setting an operation mode. CONSTITUTION:When play operation is displayed, the 3rd plunger 3 turns on to rotate the lever 4 counterclockwise against a spring 14 up to a position shown by a broken line. At this time, the projection 4a of the lever 4 presses the gently curved bevel 5ff of the peripheral part 5b of the 1st cam gear 5 in the middle of movement. When a projection 6a abuts on an end part of a peripheral projection part 7f to stop the rotation of the cam gear 5, a cam 5g rotates from a position shown by an alternate long and short dash line to a position shown by a dotted line to press up a step part 15a provided on the reverse surface of a slider 15, and an idler 18 is pressed against the flange 22a of a take-up reel shaft 22 and a driving pulley 19 to take up a tape.</p> |
