Abstract: An image projection device projects an image to a projection surface, and includes an image forming element, a refractive optical unit, and a reflective optical unit. The image forming element forms an image to be projected to the projection surface based on an image signal. The refractive optical unit has a refractive optical system including a plurality of lenses guiding light of the image toward the projection surface, the image being formed by the image forming element. The reflective optical unit includes a reflective optical system having a first mirror reflecting the light guided by the refractive optical system and a second mirror reflecting the light reflected by the first mirror toward the projection surface; and a blocking section including a blocking surface disposed at a position of blocking part of light generated in the refractive optical unit and passing through between the first mirror and the second mirror.

Abstract: A lens barrel: an optical system; a focusing manipulation unit capable of changing a focal position of the optical system in a normal photographing area and in a macro photographing area where the focal position can be changed for an object located at a position shorter than a shortest distance position of the normal photographing area; a photographing mode switching unit for switching between a normal photographing mode and a macro photographing mode; and an index ring having a normal scale and a macro scale, the normal scale indicating an object distance in the normal photographing mode, and the macro scale indicating the object distance in the macro photographing mode. Then, the photographing mode switching unit switches a display position of the index ring between the normal scale and the macro scale, and the focusing manipulation unit changes the focal position displayed on the index ring by rotation manipulation.
