described the arm will move outwardly at a preselected speed in the embodiment of fig3 the control exercised over arm 13 is such that the arm can be moved at two different speeds as well as at speeds corresponding to the sum and difference of these two precept speeds thus when sensor 21 is operated to provide an input signal arm 13 will be moved rapidly inwardly the contacting of sensor 22 will result in a comparatively slow inward movement of arm 13 sensors 23 and 24 are employed to generate signals which control the outward movement relative to the turntable of the pickup arm 13 operation of sensor 24 causing a rapid movement and operation of sensor 23 causing a relatively slow movement of the arm as in the embodiment of fig2 the raised pickup arm 13 can be lowered by contacting sensor 18 referring now to fig4 circuitry for use with the sensor arrangement of fig3 is depicted as shown in fig4 the sensors 21 22 23 and 24 each comprise an electrode pair having a first contact thereof connected directly to ground as indicated at 33 the second electrodes of each sensor pair are connected via respective diodes 25 26 27 and 28 to logic circuitry which will be described below a voltage source u is coupled via respective resistors 29 30 31 and 32 to each of sensors 21 22 23 and 24 via the aforementioned diodes as shown i e the junctions between the resistors and diodes are connected to inputs of the logic circuitry capacitors 34 35 36 and 37 are connected in parallel with each of the series connected sensor electrode pairs and diodes for noise suppression in the disclosed.
