Abstract: An easily manufacturable optical disc drive that provides for accurate writing and reading of information signals to and from a disc loaded therein by maintaining the horizontal balance of its base during operation, and that provides for smooth loading and unloading of a disc. The optical disc drive includes a base formed of a single metal plate of 1.4–1.8 mm thickness. Major components of the base (i.e., a disc rotation driving mechanism, an optical pickup and a pickup feeding mechanism) are disposed on the base in such a way that the total weight of these components is nearly evenly distributed on the base. The optical pickup is adapted to move across an optical disc between its inner and outer circumferences, while the optical disc is rotated by the disc rotation driving mechanism. The base is supported by a plurality (i.e., at least three) of supporting members, each with an elastic support piece.

Abstract: An advantage of the invention is in providing a device a device capable of accurately determining a position to which a pellet has been fired and instantaneously sending points to a display unit. Namely, because the target surface is such that inside and outside of boundary lines are at different heights, in the event of an impact making contact with a boundary line, a pellet will always impact with and apply pressure to the inside part of the target for which the points are higher. A terminal of a circuit substrate corresponding to this higher points side then makes contact so as to provide excitation, and the points can be accurately displayed. The bull's eye target device of this invention is such that a target section is provided with a target surface section provided with a central section and a plurality of ring sections, and a circuit substrate provided so as to be spaced from the rear surface of the target surface section.

Abstract: A magazine for an air gun of this invention can be freely attached to and detached from an air gun body using a magazine body, and has a plurality of pellet holders capable of being loaded with one pellet at a time. The plurality of pellet holders move orbitally about a pellet holder path and the pellets can be fed one at a time from the pellet holders towards a rotary sub chamber positioned below. With the air gun of this invention, the direction of the rotary sub chamber can be changed by shifting a rotary sub chamber positioned below the magazine, a trans link and a bolt forwards and backwards, so that the direction of single pellets dropping from the magazine can be changed by ninety degrees for feeding into the barrel. The magazine conveyor link is also interlocked so as to move to the front and rear in unison with movement to the front and rear of the trans link.

Abstract: A skew of an optical pickup device can be adjusted by a movable-side member itself which holds thereon an objective lens. A holder which holds an objective lens is supported by four spring wires such that it can be moved in the focusing direction and the tracking direction of an optical disk. A center of a magnetic circuit which drives the holder is shifted in the outer peripheral side relative to the optical disk. Elastic force of the spring wires of the inner peripheral side is suppressed by increasing the amount of a gel material bonded to the spring wires located on the inner peripheral side of the optical disk as a damping material as compared with the amount of the gel material bonded to the spring wires located on the outer peripheral side.

Abstract: It is possible, in an automatic air gun, to reduce a piston block's size and effectively use a compressed gas' pressure. A change valve and a open-close valve are positioned below a cylinder block. A change valve closing portion is exposed in a change valve gas chamber. The change valve is located so only a rod portion is positioned in the change valve gas chamber. When the compressed gas is supplied to a bullet discharge ventilating opening side, through the change valve gas chamber, the closing portion opens a bullet discharge air-supply opening thereby allowing the compressed gas to flow to the bullet discharge air-supply opening. When the compressed gas is supplied to a blow-back ventilating opening, the closing portion makes a blow-back air-supply opening change to the opening state; the change valve rod prevents supply of the compressed gas to the change valve gas chamber.

Abstract: This invention can make a valve compact in function and improve using efficiency of a compressed gas and make an air gun compact. To achieve this object, an air gun is constructed by a hit pin arranged in a cylinder portion, a valve body arranged within a hollow portion of the cylinder portion and having a bullet supplying nozzle chamber and a valve pin chamber, a gas inlet port opened to a sleeve-shaped circumferential face of the valve pin chamber, a bullet supplying nozzle arranged within the bullet supplying nozzle chamber, and a valve pin arranged within the valve pin chamber. The hit pin is pressed on a muzzle side and the valve pin is slid to the muzzle side so that an airtight state between a valve pin flange portion and a side face of the valve pin chamber on its gun rear end side is released. A compressed gas is supplied to a nozzle chamber side opening and a valve pin chamber side opening from a clearance between the valve pin flange portion and the gun rear end side face of the valve pin chamber.
