Title: Automatic tape cartridge changing mechanism
IPC: G11B15/68
Filed: 1965-08-02
Abstract: 1,121,421. Playback apparatus. SARKES TARZIAN Ino. 2 Aug., 1965 [12 Aug., 1964], No. 32896/65. Heading G5R. [Also in Division B8] A tape recorder for sequentially playing a number of tapes automatically is provided with a rectangular opening into which a tape cassette, 70 (Fig. 1), may be inserted. The cassette comprises a casing housing a number of individual tape cartridges 60 each of which includes two spools between which the tape is wound, Figs. 18-21 (not shown). Each tape is provided with two tracks, the selection of which is determined by the orientation of the cartridge in the cassette, and also by the orientation of the cassette into the machine. The cassette is pushed into the machine as far as it will go, and in this position the topmost cartridge is so situated that a drive member 168 mounted on top of a guide post 144 engages with the hole 51 to drive the spool, and the head 126 is adjacent one of the two tracks on this tape. Actuating the start lever switches on the drive motor for member 168, and causes the head 126 to move into engagement with the track on the tape. The drive to member 168 is normally transmitted via a toothed wheel 270, Fig. 14, which engages with a projection 272 on an arm 274 mounted on a flywheel 232. At the end of a tape, the increase in tension causes the arm 274 to ride up over the teeth and look in a disengaged position on arm 324. In this position the drive is disconnected from flywheel 232 and drive members 168, and is oonneoted to a cam plate 344 which controls the auto-change action. Rotation of the cam plate disengages the head 126 from the tape, rotates a pinion 472 which engages with a rack on the cassette to raise it to a position where the next tape is adjacent the head, engages the head 126 with this tape, and finally releases arm 274 to reconnect the drive. At the end of the last tape, one further stepping action is completed to lift the lowest tooth of the rack above the pinion, and the motor switches off. The cassette can then be removed, inverted, and reinserted to play the other tracks on the tapes. A manual " reject " lever is also provided for initiating a change cycle. Tape anchoring.-Each tape reel is provided with a slot, 642, Figs. 22, 23 and an adjacent irregular shaped hole 646, over which is situated a pin 650 formed integrally with the reel. The end of the tape is inserted into the slot 642 and the pin 650 hammered into the hole 646 to deform the web 648 and thus hold the tape in position, Fig. 24 (not shown). This action also slightly raises the rim portion 658 with respect to rim portion 640a to ensure that the second layer of tape round the reel lays on to the first layer without forming a bump, Fig. 24 (not shown).
