Abstract
When an observation state by an infrared LEDis changed to a photographing state by a xenon lamp, a movable mirroris pulled upward and an optical path is switched to an image sensorside. A light guideis shifted by an alignment index drive motorso that an incident portion of an alignment index is shifted from a visible LEDto direct to an infrared LED. An outgoing portion of the light guideis set at a position where an image is formed on the image sensorby a wavelength of the infrared LEDwhen an operation distance is appropriate. While changing a luminescent color, a position of a luminescent point of the alignment index is changed by switching the LED by the shift of the light guide
