Abstract: A projector with a color sensor module is provided. The projector includes a light source providing a light, a prism device refracting the light, a reflecting device reflecting the light refracted by the prism device, an optical lens receiving the light reflected by the reflecting device and forming a first light path between the optical lens and the reflecting device, and a color sensor module disposed on a second light path and comprising a light inlet receiving the light reflected toward the second light path by the reflecting device.

Abstract: An adjusting device for positioning an integration rod within an optical engine module is provided. The optical engine module includes a casing having four sidewalls defining an optical path. The integration rod is disposed in the optical path. Each sidewall has a screw hole. The adjusting device includes two adjusting screws extending through the screw holes in two adjacent sidewalls of the casing in order to abut against the integration rod, thereby adjusting the position of the integration rod in the optical path and two positioning screws extending through the screw holes in remaining two adjacent sidewalls of the casing to abut against the integration rod for immobilizing the integration rod within the casing.

Abstract: An elevating device includes first and second rack members interconnecting each other in such a manner to protrude downwardly from a lower opening of an outer casing in a double-step manner so as to be supported on a support surface. The elevating device adjusts an inclination angle of the outer casing relative to the support surface.

Abstract: A projection apparatus including an optical engine, a ring, a lens and multiple casings is provided. The optical engine is suitable for producing an image light beam to project an image onto a screen. The ring is fixed on the optical engine. The lens is disposed outside the optical engine and located at a transmission path of the image light beam. The casings are assembled to the ring and connected to each other to form a lens barrel for fixing the lens, and the lens is driven to move relative to the optical engine and the ring by the lens barrel. The projection apparatus has a smaller overall dimension.

Abstract: A portable container for playing games of chance comprises a box combined by a cover and a base, a rotatable means whose components are disposed in the cover and the base when carried. A number of bouncers are provided on the base for playing. Disks are inserted in the bouncers and bounced by the springs within the bouncers to the assembled rotatable means so that the positions of the rotatable means in which the disks drop determine the scores of the players.
