An optical head comprises a laser holder retaining a laser diode, and a holder support retaining the laser holder, and irradiates an information storage medium with laser light from the laser diode to perform recording/reproduction of information. In this optical head, the laser holder is a frame structure that fixes the laser diode, having an abutment portion protruding from a base side of the frame structure. Also, the holder support has a receiving surface that supports by abutment the abutment portion, and a through-hole that lets pass the laser light. The receiving surface is a plane approximately perpendicular to an optical axis of the optical head, the abutment portion being made as an arc surface having a central axis that passes through an emission point of the laser diode and is perpendicular to the optical axis.

A driving device includes: a bending displacement member (A), partially fixed, which is excited by electrical control to be bent and displaced; a bending displacement member (B), partially fixed, which is excited by electrical control to be bent and displaced; an elastic member () joined to the bending displacement members (A,B); a friction member (), joined to the elastic member (), which is capable of partially making contact with a body tube (); and a camera module housing () capable of housing the bending displacement members (A,B), the elastic member (), and the body tube (). The bending displacement members (A,B) may be disposed along an inner wall of the camera module housing (). The driving device may also include control means for exciting the bending displacement members (A,B).

Driving device, imaging device including the same, and imaging apparatus

An optical disk device including a tray in which recording mediums having differing outer diameters can be selectively mounted. The tray carries the recording media into the main body of the optical disk device wherein it is, chucked by a turntable. Holding members for holding the recording medium at a predetermined position relative to a mounting face of the tray are provided in a front portion and a rear portion respectively relative to the transport direction of the tray. At least one of the holding members is movable between a first holding position for holding a small diameter recording medium, and a second holding position for holding a large diameter recording medium. The holding member is biased toward the first holding position by a biasing member.

Optical disk device

An optical disc device is provided with a tray for mounting a disc or a cartridge thereon, a chassis that is laid out under the tray, and a top plate that is laid out above the tray. The optical disc device comprises two types of holding mechanisms that form either a single disc mounting space or a cartridge mounting space according to a shape of a single disc or a cartridge to be mounted in the tray, and hold the single disc or the cartridge in the respective mounting space.

Side holders are provided at either side in the width direction interior relative to stationary holder(s). Parallel link mechanism(s) is or are provided for causing side holders to move in the cartridge width direction. When a cartridge which is one of a plurality of types of cartridge other than a cartridge or cartridges of the type or types that is or are smallest in width is inserted therein, pressure from that inserted cartridge causes actuation of parallel link mechanism(s), and respective side holders move outward in coupled fashion to form insertion space in agreement with width direction dimension(s) of cartridge

A cassette loading device including the following configuration: one cassette holder is fitted into the other cassette holder so as to slide in the cassette's direction of movement relative to the other. The other cassette holder is moved in linkage with the cassette pushing operation for magnetic tape cassette inserted into the one cassette holder, with a different amount of stroke from the pushed amount of stroke for the magnetic tape cassette inserted in the one cassette holder. Also, a timing change lever which is rotationally supported at a central portion across the length, is adapted to selectively become engaged at its distal end with the magnetic tape cassette held in the cassette holder. In the terminal end of the movement of the cassette, the opening which is provided at the other end of the timing change lever is detected so that the cassette in-pulling operation starts at the timing of the detection.

A rotary head assembly has a first positioning surface and a second positioning surface provided in a rotary yoke. The first positioning surface contacts an end surface of a rotor of a rotary transformer. The second positioning surface contacts an outer peripheral surface of the rotor of the rotary transformer. A rotary yoke is fixed on the rotor by magnetic force by a motor. The rotary yoke is positioned by the first positioning surface in a thrust direction, and by the second positioning surface in a radial direction. Thus, the rotary yoke can be easily and precisely attached.

Rotary head assembly

An apparatus for selectively recording a baseband signal and a MUSE signal on a magnetic tape and for reproducing them at different speeds including: a magnetic head circuit having first and second groups of heads provided separately form each other. Each of the head groups includes four rotary heads for consecutively and helically scanning the tape to record and reproduce the baseband and MUSE signals. The apparatus further includes: an apparatus for providing a mode designating signal for designating an operational mode of the apparatus; a signal processing circuit which can process the baseband and MUSE signals, in response to the mode designating signal, for processing one of the baseband and MUSE signals; a head switching circuit for switching the connection between the signal processing circuit and the respective rotary heads in response to the mode designating signal; and a scanning speed adjusting circuit for adjusting the relative scanning speed of the rotary head and the recording tape in response to the mode designating signal. The apparatus can appropriately switch the scanning speed and the connection between the rotary heads and the signal processing circuit according to the type of signal and operational mode. Thus, the baseband signal is recorded as a two channel signal on the magnetic tape and the MUSE signal is recorded as a one channel signal. Also, the apparatus can reproduce the baseband and MUSE signals recorded according to the above-described track pattern at a different speeds, respectively.

Apparatus for recording and reproducing high resolution image video

A video signal recording/reproducing apparatus with two groups of rotary heads which respectively include one main head and two auxiliary heads is set forth. The apparatus includes a head switching device for switching one of the two auxiliary heads into operation according to input video signals and a tape speed switching device for switching the running speed of a video tape according to the input video signals. The apparatus permits the video signal recording/reproducing of both video signals having a wide band and a narrow band. The apparatus also defines an effective tape wrap angle wherein the position of head switching is removed from a screen so that the division of images within the screen is avoidable and so that noise bars produced in the boarders of these images do not appear even in the case of special reproduction. The apparatus further permits recording of video signals on a video tape while approximately conforming a line number in the center of the main tracks to that in the center of the effective lines of the TV image. Accordingly, noise bars produced by head switching and image parts with less information amount can be removed by separating and locating them out of the upper and lower ends of the screen.
