Abstract
1481657 Feeding record tapes MATSUSHITA ELECTRIC INDUSTRIES CO Ltd 1 Sept 1975 [6 Sept 1974(2) 10 Sept 1974] 35949/75 Heading G5R An end-of-play detecting mechanism for a cassette or cartridge tape recorder comprises a take-up support 50, Fig. 10, for a take-up reel, slipping clutch means 60 for tape winding detecting slipping clutch means 66, a biasing lever 63, a take-up pulley 56b with an eccentric cam body 61, Fig. 11, which has an engagement recess 61a, and a control member 62 having a projection 62d which is held out of engagement of the recess 61a by the lever 63 as long as the detecting clutch 66 exerts a biasing force on the lever 63, but which as soon as the take-up support stops rotating, engages the projection 62d. This causes an operating member 31 pivotally carried by a movable deck 13, Fig. 1, be rotated anticlockwise and thereby disengaged from a lock pin 30. The deck 13 can then return to its inoperative position causing the cassette to be ejected. The tape recorder has a stationary chassis 10, Fig. 1, supporting the movable deck, 13 on balls and oblique slots arrangement 17a, 18a; 22a, 22b, Fig. 3). A slidable plate 43, carries the head H for engagement with the tape, and the pinch roller 40. In operation, the cassette T is inserted and pushes rods 34a, 34b which cause the deck 13 to move up towards the chassis 10, the supports 50, 35 entering the reels of the cassette and the head 4 and pinch roller 40 engaging the tape whilst the slidable plate 43 is in its unoperated position. On pushing the projection 43d the plate 43 is moved to its operated position with a push-pull hysteretic locking arm 46 being locked by a pin 49a mounted on the deck 13 and the head H and pinch roller 40 withdrawn for rapid advance of the tape. On pushing an ejecting lever 25, lock pin 30 is disengaged from the member 31, thus releasing the deck 13 to return to its inoperative position and eject the cassette.
