Abstract

1,127,239. Sheet recorder; driving magnetic recording heads. TDK ELECTRONICS CO. Ltd. 8 Dec., 1965 [2 Aug., 1965 (2); 6 Aug., 1965], No. 52061/65. Heading G5R. As rim-driven turn-table 1, below a magnetic sheet (not shown), is rotated, the head 13 is driven radially inwards through the gears 5, 6 engaging a rack 4, the centre pinion 8 being held stationary by projection 10 engaging a stopping rod 11, so that the head traces a spiral path. When the head 13 approaches the centre, a projection 12 passes through slot 15 and eventually contacts kick plate 34 causing low friction pad 49 to enter hole 19 to stop the turn-table, strip 33 operating switch 38 to stop the motor. When arm 4 has been returned to its initial position, operation of starting arm 25 releases pad 49 and causes switches 32 to close. The turntable may be stopped manually by operation of arm 36. The centre pinion is released by operation of arm 21, spring 14 returning the rack to its initial position. The tongue 38 causes the plates 39 to move inwardly, thereby operating the indicator 42.
