Abstract: PURPOSE:To positively detect the ends of records by a simple structure, by mounting an electromagnetic means for turning in the horizontal direction, its control means and a positional detector so that they be used for a tone-arm. CONSTITUTION:When a tone-arm 1 traces slong a sound groove of a record and reaches the last sound groove location and a lead-out location, signals are each generated at each coil 22 and 23 for horizontal detection and horizontal drive. In this case, output signals corresponding to width in the moving direction of a window 35 set are generates from a luminous and light receiving element 37 because the wondow 35 of a shutter 34 moving in synchronous with a horizontal turning shaft 10 passes between luminous and light receiving each element 36 and 37 disposed in facing shapes. Thus, an AND 39 energized by the element 37 and the detecting signals of the coil 22 opens its gate, and supplies the output signals to a vertical drive coil 14. Consequently, the ends of records can positively be detected because the arm 1 parts from records and is stopped at a fixed location.
