摘要： A device for preventing the observing objective lens window of an endoscope from collecting moisture by directing a small flow of air over the front surface of the observing objective lens window to form a layer of air which has the same temperature as the ambient atmosphere thereby stabilizing the temperature of the window. A control valve is provided which shuts off the flow of air in the event that the pressure within the body cavity in which the endoscope is inserted becomes too high due to the flow of air. A first embodiment of the control valve includes a cylinder and piston arrangement in which at a first position of the piston air is allowed to flow through the tube to the endoscope end. At a second position of the piston, air is vented directly to the atmosphere. In a second embodiment, a lateral hole is provided in the piston with the area of the hole and hence flow of air controlled by a screw the position of which determines the area of the lateral aperture.

摘要： A locking lever is formed to include a pair of legs 16 upright from the wall of a first connector 10 and a pair of free ends 17 which continuously cross the pair of legs and provide a locking portion 18. A releasing lever 20 is formed to return to the legs from the free ends 17. A second connector 40 is provided with a hitting portion which hits against the end of the second connector 40. When the releasing lever is pushed, the free ends 17 are lifted by the theory of leverage at the furculum of the hitting portion, thereby releasing the locking between the engagement portions 18, 50. The releasing lever 20 includes a pair of arms 21 and a pressing portion 23 which continuously crosses the pair of arms. This configuration provides a connector locking structure which can prevent the base of the locking lever from being deformed and improve the feeling of clicking in coupling and capability of releasing the locking.

摘要： A portable endoscope having a control part containing an entrance end portion of a light guide for transmitting light for illuminating an object, and an illuminating light supply unit containing a light source lamp for supplying illuminating light to the light guide. A connecting mechanism detachably connects the control part and the light supply unit. A switch for turning on/off the light source lamp is provided in the connecting mechanism. When the light supply unit is connected to the control part in a predetermined state, the switch is turned on; when the former is detached from the latter, the switch is turned off. An electric resistor may be provided for gradually reducing the electric resistance between the lamp and a power supply therefor from a high-resistance state to a low-resistance state as the switch is moved from an OFF position toward an ON position.

摘要： An illuminating apparatus of an endoscope having a bulb disposed to face an entrance end surface of a light guide for illumination to supply illuminating light to the light guide. A concave mirror surrounds side and rear portions of the bulb to converge light emitted peripherally from the bulb in the vicinity of the entrance end surface of the light guide. A convex lens is formed at the distal end of the bulb to allow light emitted forwardly and obliquely forward from the bulb to be incident on the entrance end surface of the light guide.

摘要： The electrical connector has a pair of first and second terminal fittings each connected to each of a pair of first and second electrical cables and a connector housing holding the terminal fittings. The electrical connector comprises a cable distinction device for electrically connecting the first electrical cable to the first electrical cable and the second electrical cable to the second electrical cable. The cable distinction device has a cutout with a shoulder, the cutout allowing insertion of the electrical cables into the connector housing, the shoulder being positioned at a middle of an inner edge of the cutout, and the shoulder allows insertion of the first electrical cable but prevents insertion of the second electrical cable into the connector housing. The first and second electrical cables have an outer diameter equal to each other, and the first electrical cable has a protrusion projecting from an outer surface of a sheath to abut against the shoulder of the cutout when inserted in to the cutout. Alternatively, the first electrical cable may have an outer diameter larger than that of the second electrical, and the first electrical cable abuts against the shoulder of the cutout when inserted in to the cutout.
