Abstract: A projector includes a light source lamp, a projection lens, a DMD device, a temperature controlling fan, an optical part, a cooling fan, and a heat radiating plate. Preferably, the heat radiation plate is provided in a path to the fans and in close proximity to the DMD device, and includes a base portion and a plurality of heat radiating fin portions, which are provided integrally on a surface of the base portion, are spaced apart at predetermined intervals and extend in a perpendicular direction to the surface of the base portion. Each of the plurality of heat radiating fin portions has a plurality of through holes which extend in a direction along the path to the fans and are spaced apart at predetermined intervals. An outer surface of the heat radiating fin portion has a shape which reflects a shape of the plurality of through holes.

Abstract: A lens cover is provided for being held between the air outlet and the projection lens. This allows the lens cover to prevent hot air exhausted from the air outlet from running across the light path of a projected light from the projection lens when the projection of an image is desired, hence avoiding the generation of shimmers in the projected image. Preferably, the lens cover is arranged vertical to the optical axis of the projection lens for turning movement on an axis located between the projection lens and the air outlet. Accordingly, the lens cover is hardly lost.

Abstract: In a battery accommodating device, a lock member 11 is disposed on a lid 5 which is pivotally supported by a case 1 and a protrusion 22 formed on an arm piece 28 of the lock member 11 is to be engaged with an engaging portion 27 of the case 1, and a second protrusion 23 is disposed on the arm piece 28. When a shock is applied to the device or the device drops, the engagement between the protrusion 22 and the engaging portion 27 may be canceled and the lid 5 may be opened. Even in this situation, the protrusion 23 is engaged with the engaging portion 27, and hence the lid 5 rests in a state where the lid is opened by a certain angle.
