Abstract

PURPOSE:To decrease the number of component parts and to improve the operability for a recording/reproducing device for a tape which can be dubbed, by providing a means which releases the stoppage of a reproduction drive mode due to a pause means of a mechanism at one side in response to the active mode of a recording means of a mechanism at the other side. CONSTITUTION:A play bar 2 is pressed toward an arrow D, and a pause lever 6 is pressed toward the arrow D. Thus the drive of a magnetic tape 23 is stopped. Then a pin 6b is engaged with an engaging part 15f via a slope part 15e of a pause lock member 15. When a record lever 7 is pressed toward the arrow D, a lock release pin 7b turns an action lever 19 counterclockwise toward G. A contact part 19f of the lever 19 shifts a slope part 16d of a release arm 16 toward an arrow H. Thus a hook part 16e is engaged with a release part 15d. Then the member 15 is shifted upward as shown by an arrow A, and therefore the engaged state is released between the pin 6b and the part 15f. Thus the lever 6 is reset toward an arrow C. The lever 7 is kept pressed by the function of a lock member 13.
