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.

Abstract: A phosphor wheel includes a first face that has a phosphor layer, a second face located on an opposite side to the first face, a first blade provided to project from one of the first face and the second face, and a passage that sends air to the second face from the first face. The first blade is provided to send air on a side of the first face to a side of the second face through the passage during rotation of the phosphor wheel.

Abstract: A cooling device is adapted to cool a DMD including a reflection surface and a support frame for supporting the outer edge of the reflection surface, and includes first and second contact portions and a water cooling pump. The first and second contact portions each have a contact surface that is brought into contact with a side surface in a direction transverse the reflection surface at the support frame. The water cooling pump is connected to the first and second contact portions so as to cool the first and second contact portions.
