PROBLEM TO BE SOLVED: To satisfactorily maintain the engaging relation between a feeding groove and an engaging part and to increase the feeding speed of a pickup by fixing a rack member whereon the engaging part is formed for engaging with the feeding groove of a pickup feeding shaft, to a pickup supporting member and energizing the engaging part formed on this rack member to the direction of the feeding groove. SOLUTION: A pressurizing planar part 18 for pressurizing a planar part 13 of the rack member 10 is formed on a leaf spring to be fixed to the pickup supporting member 1. Engaging holes 19, 20 are formed at the positions confronted with a 1st protrusion 14 and a 2nd protrusion 15 which are formed on this planar part 13. Then, the positional relation is established so that an end part of the engaging hole 19 is abutted on an inclined part which is formed on the bottom part of the 1st protrusion 14. When the moving operation of the pickup is carried out, the planar part 13 of the rack member 10 is pressurized to the direction where the engaging part 12 is engaged with the feeding groove 9, by the pressurizing planar part 18 of the leaf spring.
