Abstract: An information terminal device which is portable and capable of charging a charge target device includes: a first body part including a display panel and a case which covers the display panel; and a power transmission coil provided at a position on a back surface of the case opposite to the display panel, for supplying power to be charged in the charge target device in a non-contact manner.

Abstract: This disk device includes a rotating portion holding and rotating a disk and a cover member provided to cover a surface of the disk, while the cover member includes a protrusion protruding from a lower surface of the cover member toward the disk, and the protrusion has a substantially sectorial shape including a pair of side portions broadening from a portion closer to a rotation center axis of the rotating portion toward a radial outer side and an outer periphery in plan view.

Abstract: In this disk unit, a tray has an air intake opening formed to extend from an upstream side in a rotational direction of a disk rotated by a rotating portion toward an optical pickup and to extend inward from outside a receiving region from the upstream side toward a downstream side in the rotational direction for incorporating air into the side a receiving surface of the tray from the side of the back surface thereof.

Abstract: A projector capable of efficiently cooling a source lamp with single air feed means is obtained. This projector comprises a source lamp, an optical component arranged on a position irradiated with light from the source lamp, air feed means for feeding air toward the source lamp, a first air guide member for guiding the air fed from the air feed means at least toward the optical component and a second air guide member for guiding the air guided toward the optical component to pass through the optical component toward the source lamp.

Abstract: An image projector allowing a lamp to be replaced alone. The lamp has lamp retention projections each extending from the periphery of a reflector. A lamp mounting member includes a plate with which the reflector of the lamp is brought into contact. The plate has a window, leaf springs, and positioning projections. Each of the leaf springs is arranged along the rim of the window with one end fixed on the plate and the other end free, and has a concave portion between the fixed end and the free end. When the lamp is placed on the positioning projections and turned clockwise, each of the lamp retention projections is inserted between the plate and the free end of each of the leaf springs to be received in the concave portion. Thus, the lamp is held on the lamp mounting member. When the lamp is turned counterclockwise, the lamp is released from the lamp mounting member.

Abstract: An image projector includes a lamp box containing a lamp, a case for forming a housing for the projector and having an opening for inserting the lamp box into the housing, a lamp housing provided inside the case and used for fixing the lamp box, and a lamp door removably attached to the case and used for opening and closing the opening. The lamp door has a screw-turning component capable of engaging with a groove on the head of the fixing screw when removed from the case, and threadable tightening/loosening can be performed by rotating the lamp door with the screw-turning component engaged with the groove in the fixing screw. This allows the lamp box to be replaced without the need for a screw-turning tool.

Abstract: A lamp unit for an image projector comprises: a cable fixing portion comprising two posts and provided to stand inside a lamp box; and a cover plate mounted to contact upper ends of the posts and of the cable fixing portion. A cable for supplying electric power to a lamp body is inserted into the space between the posts, and wound around the posts. Thereby, even when a connector at an end of the cable is pulled, the cable is fixed and does not move, with the pulling force being not transferred to the lamp body. The cover plate mounted to contact the upper ends of the posts furthermore prevents the cable from slipping off the posts. Thus, with simple cable fixing structure, the lamp body can be prevented from slipping in position without increasing cost.
