Abstract: Provided is a maneuvering device including: an input device (101) configured to detect an input operation for instructing movement of a mobile body to generate input information, a calculator (11) configured to change the input information so as to acquire an effect equivalent to a case in which a dead zone is set to the input operation, to thereby generate changed input information; and a controller (103) configured to control the movement of the mobile body (100a) based on the changed input information. The calculator is configured to change a range of the dead zone in accordance with a detection parameter detected in relation to the movement of the mobile body.

Abstract: A transportation body 1 for a flexible optical disk 10 has flexibility, and includes a rotation stabilizing board 2 having a disk-shaped form, an optical disk alignment unit 4 installed in the central part of the rotation stabilizing board 2, and a spacer 3 installed on a surface of the rotation stabilizing board 2. A combination of the transportation body 1 and the optical disk 10 can be treated as an equivalent of a conventional optical disk having rigidity, by transporting the flexible optical disk 10 placed on the transportation body 1 and by recording/reproducing information onto/from the flexible optical disk.

Abstract: To develop optical discs stored while being stacked and to load them to a plurality of recording/reproducing devices simultaneously. Trays for mounting optical discs are stacked to configure an optical disc transportation body, and the portions being exposed without overlapping when the stacked trays are viewed from the stacking direction are utilized as tray operation portions for handling. Supporting portions abutting against the tray operation portions inherent to respective trays in one to one correspondence are fixed with an interval in the vertical direction to the frames configuring a tray distributing/holding portion. The tray operation portion of each tray is held by the supporting portion at each position by moving the optical disc transportation body downward along the frames, and intervals corresponding to the arrangement pitch of recording/reproducing devices are formed between respective trays.

Abstract: A fast steering mirror has n plate springs (40a to 40d) and m drive means (50a to 50d). The plate springs (40a to 40d) are arranged such that a cross-sectional plane passing through the center of the thickness of each of the plate springs is on the same plane as the reflection surface of a mirror (20), and are arranged rotationally symmetric to each other about the center (O20). The plate springs each have a section extending along the circumference of the mirror holder, the section being obtained by dividing the perimeter of the mirror holder substantially into n sections. The drive means (50a to 50d) are arranged such that a cross-sectional plane passing through the center of torque generated by each of the drive means is on the same plane as the reflection surface of the mirror (20) and are rotationally symmetric to each other about the center (O20).

Abstract: [Problem] The problem is to provide a system with a large capacity as the recording and regenerating apparatus through piling optical disks and stocking the piled optical disks compactly. [Means to solve the Problem] An optical disk recording and regenerating apparatus to make a holding means, which includes an optical disk sucking part to suck an upper surface of an optical disk, and a partition sheet sucking part to suck a partition sheet by sucking a held area of the partition sheet and which sucks and holds at least one of the optical disk and the partition sheet, move to an optical disk drive from a tray loaded with a plurality of the optical disks which are piled through the partition sheet having the held area projecting from an edge of the optical disk and not overlapping with the optical disk when the optical disk and the partition sheet are piled.

Abstract: A position-error-signal calculation circuit (105) calculates a relative position error between a laser-focused-beam spot (103) and an information recording layer (102), and generates a focus error signal (106). A filter (108) amplifies and passes therethrough a signal component in the vicinity of the natural resonance frequency of at least one mode among the natural vibration modes of the optical disc medium (101). A drive amplifier receives through a stabilizing compensator (109) and a D/A converter (110) the focus error signal (106) passed by the filter (108), to drive an objective lens (113), thereby allowing the laser-focused-beam spot (103) to track the information recording layer (102).
