Has a configuration for direct image formation. According to this configuration, since the reflected light flux reflected outside the optical path by the reflection unit directly enters the image pickup device, the image is left-right inverted (inverted) on the image pickup device.
An image is formed. However, the image data of the image formed on the image sensor is temporarily written in an image memory or the like,
Thereafter, by reading out the temporarily written image data in a predetermined reading order set in advance, an image as an erect image can always be obtained. That is, regardless of the orientation of the image sensor and the direction of the image formed on the imaging surface of the image sensor, if the reading order of the image data corresponding to the orientation is set in advance, An image as an erect image can be obtained. Therefore, according to the configuration of the present invention, the degree of freedom in the arrangement of the imaging element and each optical member is high,
Further, since there is no need to provide a reflecting optical system such as a prism between the reflecting means and the image pickup device, the size and weight of the apparatus can be reduced.

Further, since a stop is arranged between the image pickup device and the reflecting means, a light beam outside the good image range affected by various aberrations around the objective optical system is cut by the stop, and the objective lens is cut off. Since only the good image portion which is not affected by various aberrations around the optical system can be projected on the imaging surface of the image sensor, a high-quality photographed image which is not affected by various aberrations around the objective optical system. Can be obtained.

The reflecting means may be constituted by a beam splitter that reflects a part of the light beam passing through the optical path of the one observation optical system to the outside of the optical path, guides it to the image pickup device, and transmits the remaining light beam. . The reflecting means is movably supported between a photographing position that has entered the optical path of the one observation optical system and a non-photographing position that has retreated outside the optical path,
When at the photographing position, a movable mirror that reflects a light beam passing through the optical path of the one observation optical system to outside the optical path may be used.
