ABSTRACT:
A tape marker for a tape playing machine in which tape runs past a reproducing head in a housing compartment. The compartment has a door through which tape is inserted and withdrawn when the tape is changed or edited. A marking arm having an inked marking pad is pivoted to a sleeve which is mounted on a removable compartment cover so the tape marker and cover comprise a unitary sub-assembly. A pushbutton guided in the sleeve is connected to the marking arm by a double-pivoted link. Manual depression of the pushbutton swings the marking arm to press the ink pad against the tape. A narrow rib on the tape side of the pad prints a line on the tape at the exact center of the reproducing head. When the pushbutton is released, a return spring moves it outward and swings the marking arm and pad to a stored, out-of-the-way position providing clearance for the tape when inserted or withdrawn through the door.
