Abstract:
An optical scanning device that permits the surface of an optically transparent member provided at an opening through which a light beam passes to be cleaned with an elastic cleaning member effectively without causing inconveniences such as noise and that offers high image quality has: a housing; an optical arrangement housed inside the housing and irradiating a scanned surface with a light beam; an opening through which the light beam from the optical arrangement travels toward the scanned surface; an optically transparent member provided at the opening; and an elastic cleaning member wiping the surface of the optically transparent member while being kept in pressed contact therewith, the part of the elastic cleaning member making contact with the optically transparent member being formed of a material having a higher hardness than the material of which the part of the elastic cleaning member not making contact with the optically transparent member is formed.
Abstract:
The liquid crystal display device 10 and the mobile information terminal using the liquid crystal display device 10, comprises a first liquid crystal display panel 15 disposed on one side of a light guiding plate 11 that leads out light severally to both of the front and rear sides of the light guiding plate, a second smaller liquid crystal display panel 30 disposed on the other side of the plate, and the panels and the light guiding plate are stacked, in which a circuit board 18, which controls the first and second liquid crystal display panels 15, 30 and has earth contact portions 22a, 22b at least on either one of the front face or the rear face of the circuit board 18 is laid between the light guiding plate 11 and the second liquid crystal display panel 30, and the earth contact portions 22a, 22b are in contact with a metal member (25, 40) that is provided on at least either one of the front face or the rear face of the circuit board 18. Consequently, it is possible to provide a liquid crystal display device where a thinner structure is realized while retaining a predetermined mechanical strength and having greater noise absorption, and a mobile information terminal using such liquid crystal display device.
Abstract:
A developing unit is disclosed which is configured to supply toner to a photosensitive drum in the body of an image forming device, and can be detachably mounted to the body of the image forming device. The developing includes a first developing roller and a roller contacting/retracting mechanism. The first developing roller can be arranged in a position proximate to and parallel with the photosensitive drum, or a position retracted from the photosensitive drum. The roller contacting/retracting mechanism is configured to move the first developing roller to the position proximate to the photosensitive drum when the developing unit is attached to the body of the image forming device, and move the first developing roller to the position retracted from the photosensitive drum when detaching the developing unit from the body of the image forming device.
Abstract:
A liquid crystal display device includes a liquid crystal panel, at least one optical sheet substantially rectangular in shape, where first and second openings are formed on the end edges of one side of the optical sheet at a predetermined interval, a main frame in which the optical sheet(s) are placed, and a sub-frame arranged above the main frame, in which the main frame is provided with first small protrusions jutting upward corresponding to the first openings at the top surface, while the rear surface of the sub-frame is provided with second small protrusions jutting downward corresponding to the second openings, thereupon the first small protrusions are inserted into the first openings of the optical sheet(s) and the second small protrusions are inserted into the second openings to connect and install the sub-frame to the main frame, and the optical sheet(s) are then aligned and fixed. Accordingly, the optical sheets are aligned better and firmly fixed to achieve larger display screens and thinner liquid crystal display devices.
Abstract:
An automatic document feeder (10) includes an automatic document feeder main body (11) arranged openable and closeable relative to the document reading surface (2b) and feeding the document to the document reading surface (2b) when closed to be set to a reading posture, a document guiding member (20) so supported by the automatic document feeder main body (11) as to be movable relative to the automatic document feeder main body (11), and a detecting unit for detecting a relative position of the document guiding member (20) with respect to the automatic document feeder main body (11) when the automatic document feeder main body (11) is set in the reading posture.
Abstract:
A liquid crystal display device 10 where a first liquid crystal display panel 15 is disposed on one side of a light guiding plate 11 that leads out light severally to both of the front and rear sides of the light guiding plate, a smaller second liquid crystal display panel 30 disposed on the other side of the light guiding plate, and the panels and the light guiding plate are stacked, in which a reinforcing frame 25 comprising a thin plate, which is substantially of the same size as the light guiding plate 11 and has an opening 26 substantially as large as the display surface of the second liquid crystal display panel 30, is laid between the light guiding plate 11 and the second liquid crystal display panel 30, the frame being covered by a cover 40 having an opening 42 corresponding to the display surface of the second liquid crystal display panel 30, such that the reinforcing frame 25 and the cover 40 sandwich and fix the second liquid crystal display panel 30. Consequently, a liquid crystal display device is provided with a slimmer structure while retaining a predetermined mechanical strength and assembly thereof is simplified.
