Abstract: PURPOSE:To allow the device to manage so that rough control is enough for the system as small as several steps by providing a magnetic head formed with plural magnetic coils in thin film forming for application of a bias magnetic field to a slider floated in air with respect to a recording medium. CONSTITUTION:A magnetic head on a slider 12 has a length over a recording and reproducing range (a) and consists of spiral magnetic coils 14a,14b,14c and 14d on a base 13 by thin film forming. The slider 12 is supported elastically with plate springs 15, 16 and the magnetic head is floated at a prescribed interval with the air flow when the recording medium is driven. A light beam emitting from a laser 2 is collected to a recording film 1b via an optical system 3 by arranging the magnetic coils 14a,14b,14c and 14d in this way to modulate a required magnetic field at all times in the case of seek within the range (a). Thus, the effective range of the modulation magnetic field is expanded, the magnetic head is inactivated separately from the seek of the optical head or rough operation control in several steps is enough for the magnetic head.

Abstract: PURPOSE:To obtain a small-sized device suitable for an electronic camera or the like by providing a means which detains a reflective mirror in the optical path and removes it from the optical path in accordance with the reversion of a motor and a means which returns the mirror to the optical path by forward rotation of the motor and detains it. CONSTITUTION:When a release button is depressed, a cam 16 is turned right by reversion of a motor 12, and levers 17 and 18 are depressed, and a cam face 18a turns right a tightening member 22, and a mirror 29 is removed from the optical path by right turning of a charging lever 24, a clutch 25, and a quick return lever 27 to diaphragm an aperture to a correct value. A cam 14 is turned left by forward rotation of the motor 12, and the clutch 25 is turned left through levers 30 and 31 to return the mirror 29 to the optical path. The clutch 25 is engaged with the lever 27 through levers 33, 22, and 24 by left turning of the cam 16 to detain the mirror 29. Thus, the operation of the reflective mirror 29 is controlled by forward rotation and reversion of the motor 12 to make the device small-sized and simple.

Abstract: PURPOSE:To obtain the shutter open state required at the preparatory exposure time or for a movie by providing a member which detains shutter blades, a member which holds them in this state, and a magnetic force generating means which releases this detention. CONSTITUTION:At the preparatory exposure time, a shutter rear blade 1 is turned left by an electromagnetic force to set an aperture to the open state, and a detention release lever 4 and a lever 5 are engaged with each other to suppress the right turning operation of a detaining lever 3 to detain and hold the blade 1 through a pin 12. At the main exposure time, a front blade 2 is turned left by an electromagnet 15, and simultaneously, the lever 4 is turned left to release the detention of the detaining lever 3; and when the front blade 2 reaches a position a prescribed length distant from the rear blade 1, power supply to both blades is stopped, and both blades are turned left by springs 50 and 60 while holding a prescribed slit width. Thus, one blade is detained mechanically and is detained and released electromagnetically on demand to simplify the mechanism and reduce the power consumption.

Abstract: PURPOSE:To provide a still video camera which prevents the destruction of stored content of a hard disk due to a careless erroneous operation. CONSTITUTION:This camera is provided with a camera main body 11 having the solid-state image pickup element which converts photographic information fetched through a lens to an electric picture signal and a hard disk device 30 which stores the picture signal read out from the solid-state image pickup element and can be attached to and detached from the camera main body 11. The hard disk device 30 is provided with a slide member 30a for write inhibition. A pushing switch 11b which detects the position of the slide member 30a is electrically connected to a system controller in the camera main body 11. Thus, the write of the picture signal to the hard disk device 30 is inhibited based on the output of the pushing switch 11b.

Abstract: PURPOSE:To contrive miniaturization and thin formation of the device by disposing an electric circuit board unit in a space part along a movable direction of an optical head movable part equipped with an objective lens for focusing a laser beam on a disk and capable of moving in a radial direction of the disk. CONSTITUTION:Electric circuit boards 15 - 18 are all horizontally fixed parallel to a bottom plate of a main body outer case 11, whereas the board 15 is fitted on the right side of a movable part 9 at about the same height, the board 16 on the left side, the board 17 on the lower sides of the movable pat 9, spindle motor 12 and a fixing part 10 and the board 18 on the upper side of the fixing part 10 in a position of no interference with a retreated bias magnet 13 respec tively. At the time of loading and ejecting the disk D, the bias magnet 13 is moved above the fixing part 10 in order not to interfere in a moved disk car tridge C, having, however, no interference with the board 18. Then, since a space between the boards 15 and 16 is wider than a width of the movable part 9, even when the movable part 9 is operated to seek back and forth, no interfer ence takes place. By this method, the space is effectively utilized, and the minia turization and thin formation of the device are contrived.

Abstract: PURPOSE:To facilitate the folding of a vertical part plate and a horizontal supporting part and to improve operability by providing a connecting means constituted so as to interlock and fold a vertical part plate connected to an original placing table and a horizontal supporting part having an optical means. CONSTITUTION:When a device is folded, by pushing the upper part of a vertical part plate 4, a stopper 18 is removed from a gear 12 and the gear 12 is rotated on the circumference of a gear 11a with a pivoting member B as a center. Since the gear 12 is united integrally with a pulley 13, the vertical part plate 4 and the horizontal supporting part 3 are interlocked and folded. When the ratio of the pitch circular diameter of gears 12 and 11a is 1:1 and that of the outer diameter of pulleys 13 and 16 is 2:1 and the vertical part plate 4 is folded up to the middle, the horizontal supporting part 3 is moved to the inside of the vertical part plate 4. Thereafter, when the vertical part plate 4 continues to be folded, the folding of the vertical part plate 4 is completed while a belt 17 slips with the pulley 13.
