<p>PURPOSE:To enable to set the number of times of reciprocating reproduction arbitrarily with a simple mechanism, by operating the running direction switching member of tape through the use of the mechanism constituted mechanically in detecting the end of tape. CONSTITUTION:When the contact end 18b of the cam lever 18 is at the concave 14 of the cam 14 and the cam lever 18 is shifted left with the operation of the end detection lever 24, the tape running switching member 19 is operated and the cam member 14 is turned counterclockwise until the positioning determining concave 14b and the positioning determining spring 17 are coupled. When the end detection lever 24 returns to original position, the contact end 18b is coupled with the concave 14c and running is switched reverse. Further, when the next tape comes to the tape end, the cam member 14 turns to the next positioning determining concave 14g to switch the running direction. Further, the reproduction is released with the incoming of the third tape end from the start of reproduction. Thus, the number of times of reciprocating can variably be set with the number of the concave of the cam member 14.</p> |
