  • Patent number: 10197788
    Abstract: A projector includes a color wheel module and an optical engine. The color wheel module includes a rotation device, a mount, a color wheel, and an optical sensor. The color wheel is fixed on a rotary part of the rotation device. The rotation device and the optical sensor are fixed on the mount. The mount has an anti-dust structure includes a curved surface that is opposite to a rotary surface of the rotary part and extends in a rotation direction of the rotary part. The curved surface and the optical sensor are arranged sequentially in the rotation direction. Either by shortening a distance between the curved surface and the rotary surface or by a guiding slot that is disposed beside or lower than the curved surface, dust deposited on the optical sensor can be reduced effectively.

  • Patent number: 10054848
    Abstract: A projector includes a holding casing having a hole structure, a projection lens movably disposed through the hole structure, a containing casing detachably fixed to the holding casing for forming a containing space, an image projection module disposed in the containing space, and a flexible washer. A first engaging structure is formed on an external surface of the projection lens. The flexible washer jackets the projection lens and has first and second ring structures and a connection ring structure formed therebetween. The first engaging structure is engaged with the second engaging structure of the first ring structure for positioning the first ring structure on the projection lens. The second ring structure is clamped between the holding casing and the containing casing for sealing the containing space cooperatively with the connection ring structure and the first ring structure when the containing casing is fixed to the holding casing.

  • Publication number: 20080024736
    Abstract: A shell structure is for containing one of a plurality of optic-lenses with different assembling positions to respectively assemble different kinds of optic equipments. The shell structure comprises an optic-lenses assembling frame and a containing shell provided with an assembling hole. The optic-lenses assembling frame is vertically assembled into the assembling hole and comprises a frame body provided with a frame center axis and a perforating hole formed within the frame body for the optic-lens perforating through. The perforating hole provides a hole center axis deviating from the frame center axis, so that the perforating hole can rotate to different positions to be adapted for the optic-lenses with different assembling positions perforating through when the frame body rotates around the frame center axis corresponding to the assembling hole.

  • Patent number: 7258468
    Abstract: The present invention provides an assembling structure for replaceably assembling a lamp to an image output device. The image output device includes a housing and a lens. The housing includes a first surface having an opening. The lens is positioned on the first surface. The structure of the present invention includes a body being movably disposed within the housing via the opening and a cover corresponding to the opening. The cover is positioned at a first position for covering the opening, and, as the cover is moved to a second position, the opening is exposed allowing the body to move into or move out of the housing through the opening.

  • Publication number: 20060246747
    Abstract: An electronic apparatus includes a key, at least one support, and a circuit board. The key has a first press end, a first contact end, a second press end, and a second contact end. The support is mounted onto the key and between the first contact end and the second contact end. The circuit board has a first contact point corresponding to the first contact end and a second contact point corresponding to the second contact end. When the first press end of the key is pressed down, the first contact end goes down together with the first press end to actuate the first contact point of the circuit board, and the support is against a top surface of the circuit board to prevent the second contact end from actuating the second contact point. Accordingly, the key of the electronic apparatus can function well without any error.

  • Publication number: 20060039128
    Abstract: A structure for hanging an electronic device is provided. The structure includes a supporting element, an adaptive element and a carrying element. The carrying element having a rail is disposed on the electronic device. The rail has an upper supporting plate. The adaptive element has a sliding axle. As the sliding axle slides into the rail, the sliding axle supports the upper supporting plate, and the upper supporting plane limits the vertical movement of the sliding axle. The adaptive element has a receiving space defining an opening. The supporting element passes through the opening and has a bottom plate disposed in the receiving space. In a first state, the bottom plate engages with the adaptive element, but in the second state, a distance exists between the bottom plate and the adaptive element allowing users to adjust the electronic device.
