PROBLEM TO BE SOLVED: To prevent the performance degradation in the recording or the playback of a information signal by eliminating plays due to gaps between a sliding member 38, on which a pickup 39 is mounted and a subguide shaft 36 which guides the sliding member 38. SOLUTION: The play between the sliding member 38 and the subguide shaft 36 is eliminated by attaching an elastic pressing member (for example, leaf spring) 44 to press-contact the subguide shaft 36 to the sliding member 38, and pressing the sliding member 38 on the subguide shaft 36 with the elastic pressing member 44.
