Abstract: A gas cartridge is firmly attached to a toy gun and the gas cartridge is replaced through simple operation. The gas cartridge is filled therein with compressed gas for firing a bullet. A cartridge housing portion slidably holds the circumferential surface of the gas cartridge. The lid portion of the gas cartridge housed in the cartridge housing portion is coupled to a cartridge attachment portion. A clamp arm has a roller and an extended portion and can be freely rotated around a rotation shaft. When the clamp arm is rotated, the roller presses the bottom portion of the gas cartridge in the cartridge housing portion. A raising lever has an abutment portion and is coupled to the extended portion so that the raising lever can be rotated around an installation shaft. When the raising lever is moved, the abutment portion slides on the sliding surface and rotates the clamp arm.

Abstract: It is made possible to use a toy gun that fires bullets by compressed gas without the replacement of a gas cartridge for a long time and the portability of the gas cartridge is enhanced. The air chamber body placed in the toy gun forms an air chamber. Compressed gas in the air chamber body passes through a gas discharge portion and shoots a bullet held by a bullet holding portion out of a muzzle. A valve establishes or breaks communication between the air chamber body and the gas discharge portion according to operation with an operation portion. The toy gun includes multiple gas cartridge attachment portions. A gas bomb is attached to each of the gas cartridge attachment portions. Each gas cartridge attachment portion is provided with a first valve portion. Compressed gas in the gas bomb attached to each gas cartridge attachment portion is guided into the air chamber by way of a gas introduction portion.

Abstract: A bolt has a cylindrical fit receiving portion. When the bolt slides forward, the rear part of a valve body enters the fit receiving portion. At a closed end opposed to its opening behind the fit receiving portion, a cylindrical body is provided. The cylindrical body lets the interior of the bolt and the exterior of the bolt communicate with each other. The shank of an opening/closing body is slidably placed in the cylindrical body. This opening/closing body has an lid portion at the end of the shank on the fit receiving portion side and a coming-off preventing portion at the outside end of the shank. An opening/closing body spring is placed between the closed end of the bolt and the lid portion and pushes the lid portion toward the fit receiving portion.

Abstract: A trigger sear is placed between a trigger and a bolt sear. The engagement between the bolt sear and a bolt is removed by pulling the trigger. The bolt makes reciprocating motion in the back and forth direction of the toy gun. While it reciprocates once, the bolt opens and closes a valve portion and fires off a bullet B. When the trigger is pulled, a stopper pawl and a driving pawl are engaged with a control plate having a ratchet gear structure. In conjunction with the reciprocating motion of the bolt, the driving pawl rotates and displaces the control plate in a forward direction. When the toy gun fires a predetermined number of bullets B, a sear bar is displaced. The sear bar moves the trigger sear and causes it to break away from the bolt sear.

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. These supporting members are disposed symmetrically with respect to a center line of the base along the direction of the optical pickup's movement. The symmetrical disposition of these supporting members, together with the vibration absorbing nature of the elastic support pieces and the balanced weight distribution on the base, eliminates weight shifts/imbalance caused by the optical pickup movement, thereby maintaining the horizontal balance of the base at all time during operation of the optical disc drive. The ease of manufacture can be achieved by selecting even numbers (e.g., four) of the supporting members for the base.
