| description | An object of the invention is to provide an endoscope in which an observation field of view can be easily changed using one operation member, and which displays a display image in a manner such that up-and-down and left-and-right directions of the display image are always caused to match an observation direction, even when the observation field of view is changed. To achieve the aforementioned object, an endoscope includes: an image pickup portion 20 including an image pickup device 21; an optical axis bending optical system configured to guide a light beam from an object to the image pickup portion; an operation input portion 3 which can be pivoted; an operation conversion portion 25 configured to resolve an input of the operation input portion and generate a plurality of outputs; and an operation transmission portion configured to transmit the outputs of the operation conversion portion to a plurality of movable portions. The optical axis bending optical system includes a first prism 11 that is rotatably supported around a second optical axis 02, and a second prism 12 that is rotatably supported around a third optical axis 03. The operation transmission portion includes: an image pickup portion interlocking portion 22 that rotatably supports the image pickup portion 20; and a prism rotation transmission portion that includes a first transmission member 23 configured to rotate the first prism around the second optical axis, and a second transmission member 24 configured to rotate the second prism around the third optical axis integrally with the first prism. |
