Abstract: PROBLEM TO BE SOLVED: To simply and smoothly return the positional relation between a slide member for transferring a drive force of a drive source to a head lift mechanism and a member at the drive source side for pushing the slide member to a normal state when a trouble occurs in the positional relation (abnormal state). SOLUTION: A geared motor as a drive source for operating a head lift mechanism has a cam disc 80 and a cam boss 81 protruding at an eccentric position from the rotary center of the disc 80, and a transfer member for transferring the drive force of the geared motor to the head lift mechanism is a slide member 109 which is located on the locus of a rotary motion turned approximately by a half revolution from an initial position A of the cam boss 81 and depressed in a direction by the boss 81 to slide. The slide member 109 has a surface depressed by the boss 81 and facing the cam disc 80, and this surface is formed into a slope (117b) apart further from the cam disc as going from the edge 117a depressed by the boss 81 to the opposite edge so that the cam boss 81 contacts the slope of the depressed surface when being rotated reversely to the depressing direction of the cam boss 81 to the depressed surface 117 (right piece).

Abstract: PROBLEM TO BE SOLVED: To obtain a rotary operating unit having a self-aligning function for correcting unbalance (shift of the center of gravity) of a rotator, e.g., a disc table, in which self-alignment is carried out quickly and surely. SOLUTION: An annular magnet 24 and a pair of magnetic yokes 25 sandwiching the magnet 24 are arranged in a chucking pulley being rotated by a spindle motor along with a magnetic disc. A plurality of balancer balls 13 are contained in the magnetic yokes 25. At the time of stopping or starting rotation of the chucking pulley, the balancer balls 13 are attracted to the magnetic yokes 25. In high speed rotation, the balancer balls 13 roll in the circumferential direction along the inner circumferential edge of the magnetic yokes 25 to perform self-alignment.

Abstract: PURPOSE:To make a disk device thin by a method wherein, when a caddy which houses a disk is inserted into the disk device, a movable frame is turned upward and a disk table and a pickup are inserted from below the caddy. CONSTITUTION:When a caddy 1 in which a CD-ROM 2 is housed is pulled into by an insertion completion device P4 and reaches the center of a disk table 23, a moving frame 20 is driven to turn upward. Then, the table 23 and an objective lens 24 for an optical pickup 25 are inserted into an opening in the caddy 1 from the lower part. Consequently, the table 23 is fitted into the central hole of the ROM 2, it raises the intermediate part of the caddy 1, the ROM 2 is magnetically chucked onto the table 23 by a disk clamper, and the lens 24 is brought close to the rear surface. After that, the ROM 2 is turned integrally with the table 23 by a spindle motor, and a recording and operation is performed. When the movable frame is turned up and down in this manner, a large space is not required, and a device can be made thin.

Abstract: PURPOSE:To miniaturize the titled device and to reduce its cost by storing a stepping motor, puley, and a winding member within a vertical and a horizontal distances necessary for the moving of a vertical pair of heads and a head carriage, and driving the head carriage with normal and inverse rotations in the horizontal direction by the rotation of the puley. CONSTITUTION:The stepping motor 15 and the puley 18 are arranged at perpendicular axis line state within the vertical distance and the horizontal distance l2 necessary for the movings of the pair of heads 3, 4 and the head carriage. After the loading of a disk cartridge 25, the stepping motor 15 drives the puley 18 to rotate in normal direction or inverse direction intermittently at every comparatively large angle in the directions of arrows (g) and (h). By driving puley 18, the both ends 19a, 19b of a wire 19 are selectively pulled, and the head carriage 8 is driven in a reciprocating movement intermittently in the horizontal direction. As a result, the depth and the height of the whole carrier can be made shorter.

Abstract: PROBLEM TO BE SOLVED: To provide a jet generator and an electronic device with it wherein transmission of vibration to the outside of the jet generator can be restrained without lowering a delivery amount of gas or without lowering cooling efficiency. SOLUTION: A vibration plate 3b is moved to the upward direction at the timing when a vibration plate 3a is moved to the downward direction. The vibration plate 3b is moved to the downward direction at the timing when the vibration plate 3a is moved to the upward direction. The vibration plates 3a and 3b are vibrated so that exciting force weakens with each other, and thereby, transmission of the vibration of the vibration plates 3a and 3b to a casing 1 or the outside of the the jet generator 10 can be restrained. The plurality of vibration plates are used, and the excitation force weakens with each other even when an amplitude is large, and therefore, the delivery amount of air is not lowered.

Abstract translation: 要解决的问题：为了提供一种喷射发生器及其电子装置，可以在不降低气体输送量或不降低冷却效率的情况下，抑制向喷气发生器外部的振动传递。 解决方案：在振动板3a向下移动的时刻，振动板3b向上方移动。 在振动板3a向上方移动的时刻，振动板3b向下方移动。 振动板3a和3b振动，使得激励力相互减弱，从而可以抑制振动板3a和3b的振动传递到壳体1或射流发生器10的外部。 使用多个振动板，即使振幅较大，励磁力也会相互削弱，因此空气的输送量不会降低。 版权所有（C）2007，JPO＆INPIT

Abstract: PURPOSE:To prevent the occurrence of a chucking error and also to prevent the device from upsizing in the heightwise direction. CONSTITUTION:An inner circumferential periphery on the back side of a disk center ring 30 is provided with plural extension parts 33 in parallel at prescribed intervals in the circumferential direction. A through hole 25 which extension parts 33 face to is provided on a disk table 22. Thus, since the extension parts 33 of the disk center ring 30 can be escaped along an inner circumferential surface 25a of the through hole 25 to the back side of the disk table 22, an incline of a disk mounting part of the disk center ring 30 is not large, so that a disk center ring can be exhibited enough in function. Then, because of the fact that the extension parts 33 can be escaped to the back side of the disk table 22, the size of the disk table in the heightwise direction can be set to the present size.

Abstract: PURPOSE:To make a caddy-type disk device thin. CONSTITUTION:When a caddy 1 is inserted into an insertion space 17 inside a disk device body 10 and a shutter 4 for the caddy 1 is opened by a shutter- opening mechanism 30, the shutter 4 is opened by the first half S2 of an insertion stroke S1 for the caddy 1. Then, before the shutter 4 for the caddy 1 inserted into the insertion space 17 interferes with a disk table 23, the shutter 4 is already opened.

Abstract: PURPOSE:To make it possible to stably and perpendicularly hold and load a disk without clatters at the time of perpendicularly using the disk device. CONSTITUTION:Four points on the outer periphery 4a of the disk 4 perpendicularly placed within a recess 3 of a disk tray 2 are held by four locking arms 15 to position the disk 4 onto the center O in this recess 3 even at the time of perpendicularly using the disk device. As a result, the disk 4 is held perpendicularly to the disk tray 2 with good stability and is loaded into the disk device body.
