Abstract

PURPOSE: To turn off power supply to a motor and achieve automatic stopping of the travelling body by letting the turning member provided to the travelling body displace largely in the final position of a record.
CONSTITUTION: As the stylus 26 of a cartridge 20 traces the modulated grooves 34 of a record disc, the catridge 20 gradually and subsequently turns toward the inner side of the record disc together with an arm 25 with the adjusting axis 23 as a fulcrum, along with which a guide 19 also turns to the inner side with respect to the traveling direction. In follow up to this turning, the travelling body 2 subsequently moves gradually to the inner side while travelling on the record disc. When the stylus 26 is guided in the endless groove after the modulated grooves of the disc in this way, the displacement angle of the arm 25 about the adjusting axis 23 increases to open a switch 10, thereby cutting the power supply to the motor. By detecting that the stylus has been guided into the endless groove of the record disc in this way, the travelling body may be stopped automatically.
