Abstract

1458768 Gramophone YUGEN KAISHA WATANABE KENKYUSHO 15 Feb 1974 [29 June 1973] 6954/74 Heading G5R In a battery operated gramophone having a first compartment 1a incorporating a speaker diaphragm 25 and a second compartment 1b with a turntable 3, pick up arm 20 and drive motor 8 mounted on gimbal bearings 10, 11, the depression of a rod 6 extending outwardly of the gramophone casing moves the turntable downwards on shaft 4 thus moving a peripheral rubber drive ring 3b on the turntable into engagement with the motor shaft 13 to tilt the motor against the action of a plate spring 15 so that the motor terminals 16 engage contacts 17 to apply the battery supply to drive the motor and hence the turntable. Downward movement of the turntable releases pick up stylus 23 from a recess 12 in the turntable so that the pick up arm is returned by spring 19 to a position over the start of a record formed in the turntable surface. On release of the rod the turntable is moved upwards by spring 15 into an intermediate position in engagement with the stylus and a dome 24 on the pick up arm is urged into engagement with a reinforcing member 26 at the apex of the speaker diaphragm. After the record is played the stylus drops into recess 12 allowing the turntable to be returned to its initial position during which movement the motor tilts disconnecting its power supply.
