PURPOSE:To constitute a small-sized auto reverse device which has secure contact by rotating a head base, where one erasing head is fitted at a lower position than one recording and reproducing head, according to the forward and backward directions of a tape run. CONSTITUTION:When a forward and a backward playback button are pressed at the same time, a head slider, a reverse driving lever, and a lock lever cooperate with one another to move a left and a right playback slider in the same direction, and either one enters a deep part to perform forward reproduction. Once a tape end is detected, the slider moves back temporarily and then enters again and the left and right sliders are switched, thereby performing backward reproduction. At the same time, a control slider and a driving slider move to left and right at right angles to the head sliders according to a reproduction direction, and consequently a base, where an erasing head 32 is fitted at a lower part than a recording and reproducing head 14, is rotated by a half around a shaft 39 through gears 37 and 36 to invert the order of both the heads. Thus, an auto reverse device which has secure contact is obtained. |
