Abstract

PURPOSE: To enable to cancel the inside force with a suitable force at all times, by driving the tone arm so that the output from a pair of detection elements fitted left and right of the line toward tangential direction of the sound groove of the record disc can always be equal.
CONSTITUTION: At the tone arm 2, head shell 3 or the contact of both 2, 3, left and right of the line 8 extended toward tangential direction of the sound groove of a record disc, a pair of detection elements 9a and 9b the constant of which is changed with the tension or pressure at the record playing state, are fitted. Further, the force toward outside is given to the tone arm 2 so that the forces (in this case tension) Fa, Fb exerted to the left and right detection elements 9a and 9b can always be equal substantially. Thus, since the force only toward the direction shown in the line 8 is present at this state, allowing to completely cancel the inside force.
