摘要： PROBLEM TO BE SOLVED: To provide an optical disk drive capable of simultaneously mitigating damage to an objective lens driving part caused by falling shocks or the like and preventing the sticking of dusts to an objective lens surface highly reliably without adding any component.
SOLUTION: Damage at the time of falling shocks is mitigated by using a regulation member 20 which sets the movable range of a lens holder 13 to be smaller than a predetermined moving range in the operating state in the retreating position of an optical pickup 2. The sticking of dusts to an objective lens 12 is prevented by bonding the top surface 13b of the ring part 13a of the lens holder 13 to the sealing part 20a of the regulation member 20 to seal the surface of the objective lens 12.

摘要： PROBLEM TO BE SOLVED: To provide a member bonding structure capable of obtaining sufficient holding strength even when an external force acts in the direction where bonded members are separated from each other.
SOLUTION: In the member bonding structure wherein a first bonded member 1 and a second bonded member 2 of which the materials are different from each other are bonded by bonding agent of which the affinity is greater to the second bonded member 2 than to the first bonded member 1, a recessed portion 1a and a notched recessed portion 1c contiguous to the recessed portion 1a, in which the bonding agent 3 is filled, are formed on the first bonded member 1. Further, when the force acts in the direction where the find and second bonded members are separated from each other, the notched recessed portion 1c is formed in a shape so that the cured bonding agent 3 accompanied by the second bonded member 2 can not be pulled out of the notched recessed portion 1c to the separating direction.

摘要： PURPOSE: To enable the changeover of the revolutional speed of a motor just before the end of a cassette tape in the state of fast forwarding or unwinding operation by mounting the motor capable of changing over the revolving speed stepwise by providing an electronic governor circuit. CONSTITUTION: A forward flywheel 4 is rotated counterclockwise, but the rotational force of the forward flywheel 4 is not transmitted to a cam gear 7, since the cam gear 7 is engaged with a locking shaft 22b of a trigger lever 22 at the locking part 7f and its tooth lacked part 7c is controlled to the position confronted to a gear part 4b of the forward flywheel 4. The connection for each gear step in the thrust direction is held by holding an engaging part 13d of a winding arm 13 by a holding part 71 of a thrust cam part 7j of the cam gear 7, and the connection for each gear step in the radial direction is held by holding an engaging shaft 24b of a take-up lever 24 by a thrust cam part 7m of the cam gear 7 when the operation is in the forward recording/ reproducing state, and by a thrust cam part 7n of the cam gear 7 when the operation is in the inverse recording/reproducing state.

摘要： PURPOSE:To make a device excellent in operability, small in size, light in weight, high in quality and high in reliability by sliding a slide plate holding a cassette tape(CT) in a cassette holder, thereby allowing an energizing plate not to press the CT from its back surface at a CT attaching/detaching position and allowing it to press the CT at a CT housing position. CONSTITUTION:At the ejecting position of the cassette holder 1, that is, when the slide plate 3 is at the CT attaching/detaching position, the CT 4 is inserted along the holding guide 3b of the slide plate 3 until it abuts on a stopper 3C. In such a state, the CT 4 slides in a direction shown by the arrow A by gravity along the guide 3b of the plate 3, and abuts on the stopper 3C to be in an attached state to the plate 3. When a loading button is operated, a driving lever 11 moves in a direction shown by an arrow C, and a relay gear 9 is turned counterclockwise and the energizing plate 5 is moved toward the housing position (arrow A). When the energizing plate 5 is moved along a cam part 1C and the plate 3 reaches the housing position, the plate 5 presses the CT 4 in a direction shown by arrow G. Furthermore, the energizing plate 7 is moved along the cam part 1C and a cushion member 8 presses the back surface of the CT 4 in the direction A so as to house the CT 4.

摘要： PURPOSE:To obtain a cassette loading mechanism having a good operability by moving a slide plate engaged with a cassette tape from the housing position in a cassette holder to the take out position by the utilizing a means to energize the cassette holder to the ejecting direction. CONSTITUTION:The device is provided with a lock lever 5 to hold the slide plate 2 in the housing position of cassette tape 3 and a releasing member 6 to make the operation in the direction to engage the lever 5 with the slide plate 2 in the course of operation. The slide plate 2 is moved to the taking out position from the housing position in the holder by the force of a spring 4 to press the holder 1 to the direction of ejecting position during the cassette holder 1 is moved to the direction of ejecting position from a playing of the tape 3. As a result, the tape 3 is pushed out from the holder 1 to the position easy to take out, up to the holder ejecting position. By this mechanism, the cassette loading mechanism having good operability, small size and light weight, and also necessitating no power consumption, can be obtained.

摘要： PURPOSE:To reduce the cost and to improve the operability by detecting the presence of a cassette half and constituting four kinds of modes out of three modes of a selecting switch. CONSTITUTION:In case of selecting a relay reproducing mode, when a tape under reverse reproducing is attained to its end in a 1st mechanism, while a cassette half detecting switch 10 is under the closing state in a 2nd mechanism, the relay reproducing mode is settled by stopping the mechanism 1 and forward rotatively reproducing the mechanism 2. And when the cassette half detecting switch 10 of the mechanism 2 is under the open state, a branch is connected to a process 18 to make the mechanism 1 operate the forward rotational reproducing, and hence a repeat reproducing mode is settled. Consequently, four selecting modes essentially similar to the conventional are obtained by changing the three modes. By this method, the cost is reduced and the operability is improved.
