PHOTOGRAPHING SYSTEM FOR ENDOSCOPE

摘要

A photographing system for an endoscope comprises an endoscope including a light guide and an image guide, a camera unit including a shutter button for producing an instruction signal for starting a photographing cycle and a mirror shutter for opening a light path of an image supplied from an image guide; and a light source unit including a photographing light source for producing photographing light, an observation light source for producing observation light and a reflective mirror for switching light supplied to the light guide from the observation light to the photographing light. The camera unit further includes a switch for producing a light path switching signal for operating the reflective mirror simultaneously with the depression of the shutter button and a switch closed by the mirror shutter released a predetermined period of time after the depression of the shutter button and producing a signal for energizing the photographing light source. Thus, in the light source unit the photographing light source is turned on after the reflective mirror is switched.
