20110235142 | Light Scanning Apparatus - A light scanning apparatus includes: a light source configured to emit a light beam; a deflector configured to deflect and scan the light beam from the light source in a main scanning direction; a control substrate that is configured to control driving of the light source and includes a first connection part to which the light source is connected and a second connection part for connecting an external terminal; and a housing that supports the control substrate. The first connection part is arranged within the housing and the second connection part is exposed and arranged at the outside of the housing. | 09-29-2011 |
20110235144 | Light Scanning Device - A light scanning device includes: a light source configured to emit a light beam; a deflector configured to deflect and scan the light beam from the light source in a main scanning direction; a driving source that drives the deflector; and a housing including a support wall to which the driving source is fixed. The support wall has a first surface, a second surface to which the driving source is fixed and that is deviated with respect to the first surface in a direction perpendicular to the first surface, and a third surface that connects the first surface and the second surface and is inclined to form obtuse angles relative to the first surface and the second surface. | 09-29-2011 |
20120026566 | Multi-Beam Light Source Device and Multi-Beam Light Scanning Device - A multi-beam light source device and a multi-beam scanning device including the multi-beam light source device are provided. The multi-beam light source device includes: a light source including: a cylindrical package having a side edge portion which extends in a rotational direction about a rotational axis line defined as a first direction; a plurality of light emitting units which are disposed in the cylindrical package and configured to emit laser light in the first direction; and a housing which holds the light source. The housing has a holder that holds the side edge portion of the cylindrical package to be relatively rotatable in the rotational direction. The holder is formed with at least one opening which exposes the side edge portion of the light source. | 02-02-2012 |
20120033281 | OPTICAL SCANNER AND IMAGE-FORMING DEVICE - An scanning unit scanner includes a light source and a polygon mirror unit. A front-to-rear rib is disposed between the light source and the polygon mirror unit and near the polygon mirror unit. An input side opening having a slit shape is formed as a cutout in the top edge of the front-to-rear rib. When laser light from the light source passes through the input side opening, the input side opening restricts the width of the light in a main scanning direction. | 02-09-2012 |
20120275819 | IMAGE FORMING APPARATUS - An image forming apparatus is provided, which includes a housing having a cover swingable around a rotational shaft, and first and second LED heads attached to the cover, a position of the first LED head relative to a first axis line around which a first photoconductive body is rotatable being more shifted toward the rotational shaft in a first direction than a position of the second LED head relative to a second axis line around which a second photoconductive body is rotatable, the first direction being a direction along which the first and second photoconductive bodies are arranged, the first and second axis lines being parallel to a second direction perpendicular to the first direction. | 11-01-2012 |
20130077986 | IMAGE FORMING APPARATUS - An image forming apparatus includes: a main body having an opening; a plurality of photosensitive members disposed in the main body; a cover configured to open and close the opening; and a plurality of exposure members that is provided at the cover and is configured to expose the plurality of photosensitive members, respectively. The cover includes a cover-side metal plate provided along a surface of the cover. Entire parts of the plurality of exposure members overlap with the cover-side metal plate, when seen in a direction normal to the cover-side metal plate. At least four positions of the cover-side metal plate, which surround the plurality of exposure members, are electrically grounded at a state in which the cover is closed. | 03-28-2013 |
20130164025 | Image Forming Apparatus - An image forming apparatus includes: a rotary member which rotates with respect to an apparatus main body between a first position and a second position; and a buffering member connected to the apparatus main body and the rotary member for buffering an impact attributable to the rotation of the rotary member. The buffering member includes: a hollow member; a movable member moveable between an evacuation position and an advance position; and a slide member provided to the movable member and contactable with an inner circumferential surface of the hollow member. The slide member is deformable such that a first pressure on the hollow member when the rotary member rotates from the first position to the second position is larger than a second pressure on the hollow member when the rotary member rotates from the second position to the first position. | 06-27-2013 |
20130259515 | Image Forming Apparatus - An image forming apparatus includes: a body frame having an opening, a cartridge being configured to be removably mounted to the body frame through the opening; and a cover configured to open and close the opening, wherein the cover includes a metallic reinforcement plate that is configured to face the cartridge mounted to the body frame when the cover is closed, and wherein the reinforcement plate includes a first recess part configured to receive therein a part of the cartridge mounted to the body frame when the cover is closed. | 10-03-2013 |
20130259517 | Image Forming Apparatus - An image forming apparatus includes: a body frame having an opening; a cover configured to open/close the opening; an exposure unit configured to expose a photosensitive member and being swingable between an exposure position and a retreated position; an urging member configured to urge the exposure unit from the exposure position towards the retreated position; and an interlocking mechanism configured to: swing the exposure unit from the retreated position to the exposure position against an urging force of the urging member in conjunction with the rotation of the cover when the cover is closed; and allow the exposure unit to swing from the exposure position to the retreated position by the urging force of the urging member in conjunction with the rotation of the cover when the cover is opened. | 10-03-2013 |
20140056612 | Image Forming Apparatus - An image forming apparatus including: a body frame including an opening; a cover configured to rotate between an open position where the cover opens the opening and a closed position where the cover closes the opening and including a base end portion rotatably supported by the body frame and a distal end portion; an exposure member supported by the cover and configured to swing when the cover is rotated from the closed position to the open position; a cable configured to transmit current to the exposure member; and a metal plate fixed to the cover and having a through-hole through which the cable extends, the metal plate including, a main body part, and a conduction part protruding, toward the exposure member, from the main body part adjacent to the through-hole at the distal end side of the cover. | 02-27-2014 |
