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 an operation state display system that makes a user recognize the operation state of an apparatus by preventing light from an adjacent light emitter from being made incident on a light guide.
SOLUTION: The position of a first light guide 112 is determined according to an isophotal contour showing positions where the light intensity of a second LED 120 becomes a half. A first photodetective surface 215 that the first light guide 112 has is not positioned in the closed space encircled with the isophotal contour. Consequently, light from the second LED 120 whose light intensity becomes a half is projected on the outside of the first light guide 112 from a first light projection surface 214. The second photodetective surface 226 of a light guide 122 is provided within the isophotal contour of the second LED 120. Consequently, light of high light intensity that a user easily view is projected from a second light projection surface 224. Namely, light intensity of the light projected from the first projection surface 214 is relatively lower than the light projected from the second light projection surface 224. Consequently, the user does not recognize that the light is projected from the first light projection surface 214.
