摘要： PROBLEM TO BE SOLVED: To provide a light source device for endoscopes which halts an output of laser beams by detecting an obstruction on a light path from a laser light source.
SOLUTION: The laser beams exiting from the laser light source 40 are reflected by a half mirror 29 and enter a condenser lens 28. A photoreceiving sensor 27b and an opening 27a are sequentially inserted in a first rotary shutter 27 relative to the light path of the laser beams exiting from the condenser lens 28. A photometric result by the photoreceiving sensor 27b is input in a system control circuit 42 controlling the laser light source 40. The system control circuit 42 makes the laser light source 40 emit light at the standard light volume by synchronizing with the insertion of a photometric sensor 27b in the light path of the laser beams, and simultaneously detects the light amount received by the photoreceiving sensor 27b. When the actually received light amount is smaller than a prescribed threshold value corresponding to the standard light volume, the output by the laser light source 40 is halted.

摘要： PROBLEM TO BE SOLVED: To provide a fluorescent observation endoscope apparatus capable of showing the outer edge of a dark part equivalent to a lesion included in a fluorescent image emphatically in the image.
SOLUTION: A lamp 33 and a rotary shutter 32 irradiates an object alternately with white light and exciting light through a light guide 16 and a light distribution lens. Then, the image of the object by the white light reflected on the surface of the object and the image by fluorescence generated from viable tissue are alternately converted to video signals by an image pickup element 13. A video signal processing circuit 43 respectively extracts luminance components from a fluorescent video signal image outputted during irradiation with the exciting light and a normal color video signal outputted during the irradiation with the white light, matches the levels of both, then calculates a difference of both, and specifies a part where the absolute value of the difference is between two kinds of high and low thresholds. Then, the video signal processing circuit 43 changes the color information of the specified part in the normal color video signal to the one indicating a specified color and then outputs it to a monitor 60.

SOLUTION: An air and water feeder unit 25 with a bottle 30 is equipped on a portable fiber scope 10 with a light emitting diode 19 as the light source. A pump 35 in the air and water feeder unit 25 is communicated with an air duct 26A and a water duct 26B is extended from the tip end part 15 to the inside of the bottle 30. Compressed air is fed from the pump 35 via the air duct 26A to jet out from the tip end part 15. On the other hand, compressed air from the pump 35 is fed into the bottle 35 via a check valve 34 in a cap 32. As a result, water W in the bottle 30 is flowed through the water duct 26b in the bottle 30 and jetted out from the tip end 15.

摘要： The mounting secures a source unit (10) to a frame (1). A first protrusion (21) extends at right angles from a surface of the unit towards the frame and a second one (23) from the frame towards this face on the unit. Parallel to the frame and the unit face is an elastic component (25) joining the protrusions to each other. This component can have an elasticity constant at which low-frequency vibrations of from roughly 50 to 60 cycles per second are absorbed, and it can be of hard rubber, with screwed studs (26a) inserted in it. Nuts on the stud ends hold the component tight between the protrusions.
