摘要： An endoscope includes light emitting devices arranged in the distal end portion of its insertion unit, and at least one elongated heat-radiating member. One end of the radiating member is arranged in the vicinity of the light emitting devices and the other end is arranged in a predetermined position adjacent to the proximal end of the insertion unit. In observation using the endoscope, a decrease in the amount of illumination rays or the occurrence of image noise can be prevented, the decrease and the noise being caused due to heat generated by LED illumination lights arranged at the distal end of the insertion unit. Therefore, observation can be performed for a long time in good conditions.

摘要： According to the present invention, an endoscope system having an insertion member thereof wound about a drum comprises an electronic endoscope, a drum, an angling input unit, a motor-driven angling unit, a camera control unit, a motor-driven angling control circuit unit, and a stowage case. A bending section included in an insertion member of the electronic endoscope is motor-driven to bend, and a solid-state imaging device is incorporated at the tip of the insertion member. The insertion member is wound about the periphery of the drum. The angling input unit is separated from the electronic endoscope, and used to enter a direction of bending in which a user wants to bend the bending section. The motor-driven angling unit is incorporated in the drum, and includes a driving source for driving a driving mechanism that drives the bending section. The camera control unit controls the solid-state imaging device, and includes a signal processor for processing an electric signal sent from the solid-state imaging device to generate a video signal. The motor-driven angling control circuit unit controls the movement of the bending section. The drum is rotatably stowed in the stowage case freely.

摘要： An illumination device (1a) includes a light source section (21) outputting excitation light; a fluorescent member (22) excited by the excitation light to emit illumination light; a first light transmitting section (24) disposed between the light source section (21) and the fluorescent member (22) to guide the excitation light output from the light source section (21) to the fluorescent member (22); and a second light transmitting section (25), which is arranged closer to the distal side than the fluorescent member (22) to guide the illumination light emitted from the fluorescent member (22). According to the invention, it is possible to provide an illumination device and an endoscope apparatus capable of exciting the fluorescent member to radiate illumination light, without directly radiating laser light from the light source section to the outside, even if a bending portion or more distal side than the bending portion is damaged in an insertion part.

摘要： A cylindrical surface on which an insertion portion where a curving portion is provided is wound for containing is formed in a drum portion rotatably supported by a fulcrum. Inside the cylindrical surface, an electric drive unit such as motors moving back and forth manipulation wires transmitting driving forces curving the curving portion is contained. By instructing a curving direction with a joy stick provided through a cable outside the drum portion, the curving portion is curved in a desired direction through the electric drive unit. A monitor displaying an image to be observed through a cable is located outside the drum portion.
