Abstract

PURPOSE: To obtain a small-sized information recording/reproducing unit in which the moment acting to a mounting table is reduced. CONSTITUTION: Press members 37-39, 45-41, respectively supported eccentrically by shafts 36, 44, are further supported on a mounting table 21 so that they are turned together with the shafts 36, 44 retractively from the mounting face. Rotary members 41, 50 are born on the lower surface of the mounting table 21 rotatably in a plane extending in the moving direction A of the mounting table 21. Bevel gears 40, 49 secured, respectively, to the shafts 36, 44 are meshed with gear parts formed, respectively, on the rotary members 41, 50. The rotary members 41, 50 are energized by coil springs 42, 51 so that the press members 37-39, 45-41 project from the mounting face. Pins 43, 52 of the rotary members 41, 50 are then brought close to the action point P3 of driving force of a motor 27. Since friction of the rotary members 41, 50 is low and the reaction point is close to the action point P3 of the drive means, driving force of the rotary members 41, 50 and the moment acting on the mounting table 21 are reduced.

In order to restore against the frictional force of 1 and the frictional force with the spherical portion 11b, the coil spring 14 also needs a sufficient biasing force. Therefore, in addition to driving the mounting table 2 to the motor 8,
A high torque is required to drive the pressing member 11 and the sliding member 12 against the urging force of the coil springs 13 and 14 and the frictional force applied to the sliding base 12, so that the device can be downsized and the cost can be reduced. There is a problem that it is difficult to do.
