Abstract

PURPOSE: To enable the speed control for the device, by performing speed control while giving a damping force according to the pulse width signal to a moving member by a drive means driving the moving member.
CONSTITUTION: The device is provided with guide rails 5a, 5b, a moving member 4 free of linear movement along the guide rails 5a, 5b while supporting a pickup arm, and a drive means driving the moving member 4. The device also includes a pulse generating means generating pulse signals according to the mobile speed of the moving member 4 and a pulse width measuring means 23 measuring the pulse width of the pulse signals and outputting the pulse width signal according to the pulse width. The speed control is made while giving a damping force of a drive means according to the pulse width signal to the moving member 4.
