Abstract: The present invention is a unit for eliminating the fluctuation of luminous energy reduction by keeping the response time of a shading mechanism constant even if a diaphragm opening degree differs when reading every pixel by setting a shading period. This unit is provided with a shading mask having a quadrangular or V-shaped opening and moves a shading shutter in the horizontal direction perpendicular to the vertically moving direction of a diaphragm plate. Therefore, a shading period is set in accordance with the constant response time of the shading shutter and the rate of luminous energy reduction becomes constant. Moreover, a high-quality static image having a stable brightness can be obtained by reading the signal of every pixel obtained by a CCD through one-time exposure while using the shading period and then pixel-mixing signals. Furthermore, it is possible to use the Archimedean spiral for the outer periphery of the diaphragm plate or the shading shutter.

Abstract: An endoscope conduit controller makes it possible to selectively use both fluid control by a mechanical valve and fluid control by a solenoid-valve unit in one system. The controller is constituted so that both a mechanical suction member and an electrical suction member having a solenoid-valve opening/closing switch can be removably set to a catching port of a catching part provided for a case body of an endoscope operation part. Moreover, the controller is configured so that an operation signal of the electrical suction member is transmitted to a solenoid-valve unit by electrical connection unit set in an endoscope or through an external signal cable or the like. Furthermore, the same is true for the case of air supply/water supply. Thereby, it is possible to selectively perform fluid control by a mechanical valve or fluid control by a solenoid-valve unit in one endoscope.

Abstract: The present invention is an imaging element assembly unit in which it can easily be promoted to make the diameter of the tip portion of an endoscope thinner by changing the configuration of a circuit board in relation to an image element. In this assembly unit, an imaging element body formed while holding a lead portion between an electrode of a CCD and a cover glass is produced, for example, on the TAB system, and this imaging element body is connected to a circuit board having a storing groove. Then, the width in the electrode arranging direction of this circuit board is formed shorter than the width in the electrode arranging direction of the CCD, and at a position where both ends of this circuit board retreat from both ends of the CCD, these are connected by a lead portion. By doing so, the diameter of the tip portion can be made thinner since the sides of both ends of the circuit board arranged on the side of the inside peripheral surface of a tip portion holding barrel retreat inside.

Abstract: A guide tube which stabilizes a guide position of a scope inserted into an object to be observed and serves to prevent a surface wall portion of the object to be observed from being pinched by a leading end. A metal ring and a hard plastic ring having a ring like convex portion are attached to a leading end of a main tube of the guide tube. The ring like convex portion is made, for example, of an elastic polyurethane resin and a protruding end has an inside diameter D1 which is slightly smaller than an outside diameter of a scope to be guided. The guide tube is capable of bringing the scope into close contact with an inside of the convex portion. Furthermore, the metal ring makes it possible to confirm a location of the guide tube by x-ray radioscopy inspection.

Abstract: Light-emitting means for emitting a light beam for sterilizing a gaming medium is disposed in a gaming machine itself at a position where the light beam irradiates a stored gaming medium or a passing gaming medium, the light-emitting means being shielded from eyes of a player. In particular, the gaming machine is a ball-shooting gaming machine or a coin or medal gaming machine. Specifically, the light-emitting means is disposed at a position where the light beam irradiates a gaming medium flowing into storage means within the gaming machine or a gaming medium stored in the storage means. Specifically, the light-emitting means is disposed at a position where the light beam irradiates a gaming medium stored in a tray located outside the gaming machine. Preferably, the light beam is an ultraviolet ray. As a consequence, the antibacterial specification of the gaming machine becomes more effective, and an antibacterial specification is newly realized in the case of the coin or medal gaming machine.
