Abstract
A support mechanism for an optical block provided with an optical head, wherein provision is made of a reference shaft and a support shaft attached in parallel to the reference shaft, the optical block being supported between the reference shaft and the support shaft in a movable manner by positioning rotational members which are provided at one side of the optical block and which are for positioning and guiding at two locations along the axial direction of the reference shaft and by supporting rotational members which are provided at the other side of the optical block and which are for supporting and guiding the optical block at two locations of the support shaft corresponding to the two locations along the axial direction of the reference shaft. The supporting rotational members for supporting the optical block with respect to the reference shaft are elastically supported so as to be able to approach and move away from the optical block, so even when there is a fluctuation in the distance between the reference shaft and the support shaft supporting the optical block, the occurrence of rotational motion about the direction along the direction of movement of the optical block can be suppressed.
