PROJECTOR

The invention provides a projector which is provided with a shutter unit and is small in size. A projector according to the disclosure includes a projection optical device projecting image light onto a target projection surface, and a shutter unit that is arranged at a light incident side of the projection optical device and that can block an optical path. The shutter unit has a drive motor, a transmission member transmitting a rotational drive force of the drive motor, and a shutter member arranged on the optical path and moving, linked to a movement of the transmission member. The shutter member is provided facing a facing area facing the projection optical device. At least a part of the transmission member is provided facing the facing area. The drive motor is provided outside the facing area. 本发明提供一种投影仪，其具备遮挡单元并且小型。本发明的投影仪的特征在于，具备将图像光投射到被投射面的投射光学装置以及配置于所述投射光学装置的入射侧并能够阻断光路的遮挡单元。遮挡单元具有：驱动马达；传递驱动马达的旋转驱动力的传递部件；以及配置在光路上并与传递部件的移动联动地移动的遮挡部件，遮挡部件与对置区域对置地设置，该对置区域与投射光学装置对置，传递部件的至少一部分与对置区域对置地设置，驱动马达设置在对置区域的外侧。
