PURPOSE:To enable sure operation with a simple operation, by moving the head to the program search location slightly back to the play location, by only operating two sliding cam plates respectively and selectively. CONSTITUTION:The device provides two sliding cam plates 4, 5 which can be moved selectively to the operating position, head stand 10 going forward to the play position when either one sliding cam plate is moved, and means slightly retrogressing the head stand 10 from the play position when both the sliding cam plates 4, 5 are moved to the operating position. This retrogress is made that the movement is blocked since the pinch roller holder 17 supporting the pinch roller 21 is in contact with the cam plane 6f of the slinding cam plate 6 being the operating position for the roller 17c regardless of the depressing operation of the pressing arm 13. Thus, the pinch roller 21 is detached state without contacting with the capstan shaft 23. |
