Abstract: PURPOSE: To prevent a cartridge body from touching a disc or a center core even when the position of cartridge body is shifted due to vibration or impact. CONSTITUTION: The gap generated between a holding means and a locking means therefor when a disc cartridge 30 is held at a recording/reproducing position, i.e., the maximum possible positional shift D2 of a cartridge body 31, is set smaller than the gap D3 between the outer circumferential surface of a center core 33 and a cartridge body 31, and the gap D4 between the outer circumferential surface of a disc 32 and the cartridge body 31 (D4>D3>D2). In other words, the cartridge body 31 can be prevented from touching the center core 33 or the disc 32 by simply determining the relative relationship of gaps D2, D3, D4 at respective parts without requiring strict control of machining accuracy at each part. Since additional mechanism for securing the cartridge body is not required, the structure is simplified resulting in the reduction of the cost and size.

Abstract: PURPOSE: To simplify a disk cartridge drawing and ejecting mechanism. CONSTITUTION: A hook pin 27 capable of restraining in a recessed groove 42 for positioning a disk cartridge 30 is fitted to a rotary link 48. By vertically moving the hook pin 27, the disk cartridge 30 is drawn into or ejected from a disk device main body. The rotary link 48 is freely rotatably fitted to a rotary shaft 49 of a chassis 11. A free end 53B of a coil spring 53 is restrained on a restraining piece 52 of the rotary link 48. A fixed end 53A of the coil spring 53 is restrained on a restraining pin 54 of the chassis 11. When the rotary link 48 is rotated by a prescribed angle, a straight line connecting the fixed end 53A and the free end 53B of the coil spring 53 is disposed to the side opposite to the previous state as against a straight line connecting the rotary center of the rotary link 48 and the fixed end 53A. Consequently, energizing force of the coil spring 53 to be worked on the rotary link 48 is reversed.

Abstract: PROBLEM TO BE SOLVED: To provide a disk driver which has highly reliable by avoiding collision with an objective lens of a pickup mechanism and other components even when a disk is inserted obliquely from a slot, and to provide an electronic apparatus having the disk driver. SOLUTION: A projecting plane 150a is formed integrally from a cover plate 150 on the cover plate 150 covering the top surface of a pickup unit 22 in the disk driver at an end part of a slot side where a disk is inserted and ejected. Further, a sheet member 151, for example, artificial leather or the like is pasted onto the projecting plane 150a. Since the providing of the projecting plane 150a makes the projecting plane 150a control an insertion angle even though the disk is inserted inclinedly to smoothly guide the disk in the direction of a disk mounting part 23, the disk is prevented from colliding with the objective lens 25a of the pickup mechanism 25 to make flaws on the disk and the objective lens.

Abstract: PROBLEM TO BE SOLVED: To obtain a head suspension for a disk device, a suspension capable of preventing breaking of a gimbal by impact, failure of a disk by head slapping, and destruction of sliders by mutual sticking or collision. SOLUTION: A suspension 11 is provided with a limiter 17 for limiting the operating range of a load beam 14 which is formed by extending a part of a base 12 for attaching the suspension. As a result, displacement of a load beam is limited by the head suspension for a disk device; hence, a gimbal is prevented from coming into contact with the disk cartridge, even if a strong inertia force is imparted to the suspension by impact or the like, so that the gimbal is protected from destruction.
