Abstract: A display device according to the invention has a passage between an image generation device (DMD) and a lamp, wherein the passage guides airflow to the vicinity of a reflector of the lamp, and, after the airflow cools the DMD, the airflow can further cool heat generated by a filter which converts light from the lamp to an image light corresponding to video signals of R, G, and B, and by a light pipe which uniformalizes the in-plane intensity distribution of light incident to the DMD.

Abstract: A floor frame supporting structure for an operator cabin on a construction vehicle, which is capable of absorbing vibration and large shock loads and of preventing rolling of the operator cabin and which has a simple construction, includes buffer support members (10L, 10R) which connect bearings (13) clamped at a front right side portion and a front left side portion of a floor frame (2) of the operator cabin (1), and joint members (11L, 11R) which are movably clamped to brackets (4L, 4R) fixed to the vehicle frame (3). A rear right side portion and a rear left side portion of the floor frame (2) are supported by rubber mount viscous dampers (20L, 20R) which are mounted on brackets (5L and 5R) fixed to the vehicle frame (3). The mounted positions of the rubber mount viscous dampers are approximately as high as the center of gravity of the operator cabin.

Abstract: A tray assembly (59) on which a cassette can be mounted can be reciprocated in a horizontal direction by a carriage system (4, 80, 76). When the tray assembly (59) is positioned above a tape drive section in a cabinet, it can be reciprocated in a vertical direction by a lifter system (2, 14, 30), holding the cassette in it.
