Abstract
A reel holder for use in a tape winding apparatus comprises a cylindrical drum unit which is rotated by the tape winding apparatus. A plurality of lock pins are radially movably mounted in a peripheral portion of the drum unit. Each each lock pin is axially movable between a projected position wherein an outer end thereof is projected outwardly from a cylindrical outer wall of the drum unit and a retracted position wherein the outer end thereof is retracted into the drum unit. First and second buttons are mounted on an axial end of the drum unit. Each button is movable in parallel with the axis of the drum unit between raised and depressed positions with respect to the axial end of the drum unit. A transmission device is installed in the drum unit and operated in such a manner as to move the lock pins to the projected position when the first button is moved to the depressed position and permit the lock pins to return to the retracted position when the second button is moved to the depressed position.
