Abstract

PURPOSE:To contrive the miniaturization of the titled device, by constituting it so that an optical head can be movable by releasing the engagement of a first and a second teeth, when a solenoid current is allowed to flow, and both teeth are engaged and the optical head is fixed, when the current is interrupted. CONSTITUTION:In a part of a movable part 5 of an optical head 1, the first teeth 13 shaped like a rack is formed, and also, the second teeth 14 shaped like a rack is formed in a freely rotatable lever 15 so as to be opposed to said first teeth 13. Subsequently, the second teeth 14 are engaged or released by bringing a lever 18 to turning operation by the operation of a solenoid 11, and also, when a power source is applied, the first and the second teeth 13, 14 are released from each other so that the optical head 1 can be moved, and also, when the power source is interrupted, the optical head 1 is fixed by engaging the first and the second teeth 13, 14. Accordingly, it will suffice that the solenoid 11 can generate force required for engaging the teeth 13, 14 by turning the lever 18. In such a way, a miniature solenoid which is scarcely heated is enough, and the device can be miniaturized.
