Abstract
An object of the present invention is to provide a projection apparatus capable of appropriately performing control relating to rotation of the projection lens. A projection apparatus according to a first aspect of the present invention includes a housing; a power supply; and a projection lens attached to the housing, the projection lens having a holder and a locking mechanism unit that brings rotation of the holder into a locked state or an unlocked state. Rotation of the holder is in the locked state when the power supply has been turned on. With the first aspect, since the power is turned on in a state in which the projection lens is not rotatable, the locked state can be safely unlocked by user's intention and the holder can be rotated.
