摘要： A light-source driver for a light-source unit detachable from an endoscope body of a portable endoscope is provided. The light-source driver comprises a step-up controller, a first switch, and a second switch. The step-up controller supplies stepped-up voltage from a power source to a light source. The first switch's status switches between the On-state and Off-state in connection with the attachment and detachment of the light-source unit from the endoscope body. The second switch is connected to a break-control terminal of the step-up controller for setting a standby mode of the step-up controller. The On-state and Off-state of the second switch are controlled by the On-state and Off-state of the first switch, and the step-up controller is set to the standby mode when the light-source unit is detached from the endoscope body.

摘要： PROBLEM TO BE SOLVED: To provide a light source device for an endoscope capable of retaining the quantity of white light emitted from a light guide constant as much as possible even if the quantity of light emitted from a white light source is reduced.
SOLUTION: The diameter of the white light emitted from the white light source 201 is reduced by afocal optical system 203 and condensed by a condenser lens 207 to enter the light guide 101. A second lens 203b of the afocal optical system is fixed inside a movable lens-barrel 211 with a screw and a gear formed on the outer surface. The movable lens-barrel 211 is screw-engaged with a fixed lens-barrel 212 with a screw formed on the inner surface. A pinion 214 of a focus adjusting motor 213 is engaged with the gear of the movable lens-barrel. A control part 21 turns on the white light source 202 and drives the focus adjusting motor to regulate the light quantity based on the output of a light quantity sensor 220 which receives a component reflected in a dichroic mirror.

摘要： PROBLEM TO BE SOLVED: To provide a light source unit for endoscopes which enables the accurate notification of the abnormality of the light source with a simple structure.
SOLUTION: A fiber scope 10 comprises a scope body 20 and a light source device 40 detachably mounted on the scope body 20. A display window 60 is provided on the surface of the light source device 40. Illumination light emitted from a light source 50 is mainly admitted into a light guide 58 as indicated by the arrow A to illuminate an object to be observed. A part of the illumination light is admitted into the display window 60 as indicated by the arrow B. Thus, when the illumination light fails to be emitted due to any abnormality in the light source device 40 despite a direction given for the emission of it, this enables an operator to detect the abnormality of the light source device 40 immediately by watching the display window 60.
