摘要： The driver has a warning lamp (LED3) indicating that an output voltage of a battery (19) falls on or below a predetermined value. A switch switches-on and switches-off the warning lamp during a switched-on condition and a switched-off condition of another switch, respectively. The former switch is activated when the former switch is switched-on and the output voltage falls on or below the predetermined value, where the former switch is switched-off when a light source unit (12) is detached from an endoscope body (11) of a portable endoscope (10).

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： 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 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.

摘要： PROBLEM TO BE SOLVED: To illuminate a subject with always appropriate brightness from the start of use of a light source till the end of the life of the light source. SOLUTION: The device comprises a short-arc type lamp 22, a lamp power supply part 26 and a timer circuit 32 for measuring the accumulated time of lighting the lamp 22. The lamp power supply part 26 drives the lamp with the electric current I0 (temporary current) of 60% of the rated current till 100 hours elapse (an unstable light quantity period) from the start of use of the lamp 22. After the elapse of 100 hours (a stabilized light quantity period), the lamp power supply part 26 drives the lamp 22 with the rated current I. COPYRIGHT: (C)2007,JPO&INPIT
