Title: Record players
IPC: G11B3/095
Filed: 1974-01-31
Abstract: 1480952 Pick up arm movement control BSR Ltd 31 Jan 1975 [31 Jan 1974] 04555/74 Heading G5R In an automatic record player in which the record change cycle of operations is controlled by the usual drive gear 39 driven from turntable pinion 38, the movement of the pick up arm is controlled via a rotatable member 43 which is driven from the drive gear and releasably coupled to a rotatable selector plate 45 which in turn is releasably coupled to a pin 49 for driving the pick up arm during its inward movement. On clockwise rotation of the drive gear 39, during start of a change sequence, the rotatable member 43 is turned clockwise by the direct link 41 and during the initial movement the pick up arm is lifted by apparatus (not shown) including a cam track on the member 43 acting on a pick up arm lift spindle. In addition an end 51 of spring 50, attached at its other end to the member 43, engages the pin 49 connected to the pick up arm vertical spindle to move the arm outwardly towards its rest and at the same time the selector plate 45 is rotated clockwise due to friction coupling with the member 43. When the arm reaches its rest further rotation of the member 43 causes spring 50 to be stressed and its end 51 to move away from a lug 52 depending from the member 43. During this rotational movement of plate 45 an extension 60 of the plate engages part 61 of switch-off lever 62 to move a further part thereof into the path of movement of an abutment 66 on drive gear 39. After a record change by apparatus (not shown) the member 43 is now rotated anticlockwise turning the selector plate anticlockwise so that the pin 49 which moves the pick up arm is trapped between the spring end 51 and the abutment 48 of the selector plate. The arm is moved inwardly until one of the steps 46 on the selector plate engages a step 47 set in position in dependence on record size. The movement of the selector plate also moves the switch-off lever to prevent part 65 of the lever being engaged by the abutment 66. The member 43 continues to turn so that the lug 52 engages the spring to move its end 51 away from the pin 49 and the pick up arm raising spindle is acted on to lower the pick-up into contact with the record. When the last record has been played a pin 56 is moved to stop the movement of the selector plate after outward movement of the pick up arm to its rest. As a result the switch-off lever is not removed from the path of abutment 66 and the apparatus is switched off.
