Title: Record player
IPC: G11B3/085
Filed: 1974-09-27
Abstract: 1485408 Pick up arm control PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 27 Sept 1974 [1 Oct 1973] 42161/74 Heading G5R The set down position of a gramophone pick up stylus for playing different diameter records is controlled by sensing elements disposed on the gramophone turntable which are or are not depressed depending on record diameter. In a player for 17 cm and 30 cm records sensing element 10 is depressed by a 30 cm record whereby abutment member 12 on pivotable plate 14 is engaged by part 11 of the sensing element to move the plate and with it an abutment lever 7 to a position in which a sensing pin 4 on a plate 3 movable with pick up arm 1 engages step 6 on the abutment lever 7 at the set down position for 30 cm records. The final part of the pivoting movement of plate 14 is under the control of spring pawl element 18 as it moves into locking engagement with notch 17 on the plate so that on subsequent revolutions of the turntable the part 11 of the sensing element does not engage abutment 12. The plate 14 remains locked in this position during subsequent play of 30 cm records and is moved to and locked in its other position only when a 17 cm record does not depress the sensing element so that its part 11 engages abutment member 13. In a second arrangement Figs. 3 and 4 (not shown) for a record player of 17, 25 and 30 cm records two sensing elements are included which act on rockers disposed on the underside of the turntable which in turn act on abutment members to pivot a plate into one of three locked positions each corresponding to a different record set down position. The plate is also coupled to a switching circuit for controlling the turntable drive motor speed. Movement of the pick up arm from its rest to the set down position is automatically controlled on operation of a switch lever 61 which on being pivoted to the position shown in Fig. 5 spring urges arm 63 in an anticlockwise direction about its pivot against the restraining influence of a dashpot 65. During the first part of the movement of the arm inclined plane 67 lifts rod 74 so that the pick up arm 25 is lifted and sensing pin 28 on arm 27, which can slide but not rotate with respect to tone arm spindle 26, is raised to the level of set down abutments 29-31 on lever 32. Level part 68 of the arm 63 now moves under the lifting rod 74 and a pin 70 on the arm engages an edge 71 of an element 73 frictionally coupled to the tone arm spindle to move the arm inwards to the set down position defined by engagement of pin 28 with the appropriate abutment 29-31. The other inclined plane 69 now moves under the lifting rod to lower pin 28 out of engagement with the abutment lever 32 and to lower the pick up arm to the turntable. At the end of record play rod 75 is arranged to return switch lever 61 to its off position so that arm 63 is returned to its initial position under control of the dashpot during which the pick up arm is raised and returned to its rest.
