    Abstract: An object of the present invention is to provide a projection apparatus capable of appropriately performing control relating to a rotation state and/or a movement state of a projection lens. A projection apparatus according to an aspect of the present invention includes a housing; a light source; a control unit; and a projection lens attached to the housing, the projection lens having a holder, a detection unit that detects a rotation state of the holder, an emission optical system, and a locking mechanism unit that brings rotation of the holder into a locked state or an unlocked state. The projection lens is displaceable between a first position at which a rotation state of the holder is a housed state in which the emission optical system faces the housing and a second position at which the emission optical system does not face the housing by rotating the holder. The second position includes an upper position at which the emission optical system faces an upper side in a vertical direction. The control unit turns off the light source when a rotation state of the holder is the first position. The control unit turns on the light source when the rotation state of the holder is at the upper position. When the light source is turned on in the housed state in which the emission optical system faces the housing, the light emitted from the emission optical system hits the housing, and the temperatures of the projection lens and the housing may increase, which may cause an adverse effect. However, when the rotation state is the housed state, the control unit turns off the light source, thereby preventing the adverse effect.

    Abstract: An object of the present invention is to provide a projection apparatus capable of appropriately performing control relating to rotation of a projection lens. A projection apparatus according to a first aspect of the present invention includes a housing; a power supply; a control unit; and a projection lens attached to the housing, the projection lens having a holder, a detection unit that detects a rotation state of the holder, and a locking mechanism unit that brings rotation of the holder into a locked state or an unlocked state. The locking mechanism unit does not bring rotation of the holder into the locked state when a rotation state of the holder is other than a specific state. The specific state is a rotation state in which the locking mechanism unit is capable of bringing rotation of the holder into the locked state. When rotation of the holder is not brought into the locked state, the control unit disables an operation relating to the locked state or an operation of turning off the power supply.

    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.
