<p>PURPOSE:To economize a space and reduce a production cost by using the motor of a recording and reproducing device commonly as a driving power source for an automatic inversion mechanism. CONSTITUTION:When switching board 30 is in the state shown in the figure and magnetic tape 35 which is held between capstan 12 and pinchroller 16 is caused to run in the arrow direction, namely, the first direction and is wound up by reel axis 20, protruded axis 49 of driving piece 46 is brought into contact with stop concave part 51' of moving material 52 to move moving material 52 in the right direction as shown in the figure if the end of tape 35 is detected. Switching board 30 connected to material 52 is rotated in the clockwise direction from the state shown in the figure by the movement of moving material 52. Then, magnetic tape 35 is held between capstan 12' and pinchroller 16' and is caused to run in the second direction opposite to the arrow and is wound up by reel axis 30'. Thus, since the automatic inversion mechanism of the tape is operated by using the motor as a powder source, the space can be economized, and the cost can be reduced.</p> |
