Abstract:
A document reading device is capable of preventing distortion or twisting occurring in a document conveying device from being transmitted to a reading carriage incorporated in the document conveying device. A document reading device includes a second reading carriage provided in a document conveying unit and configured to read a surface of a document different from a surface read by a first reading carriage, a support frame having a support surface supporting the second reading carriage, a retaining member retaining the second reading carriage by sandwiching the same between itself and the support frame, and an elastic member provided between the second reading carriage and retaining member to press the second reading carriage against the support frame. One of the support surface of the support frame and a supported surface of the second reading carriage supported by the support surface is formed into a curved surface.
Abstract:
An image scanning apparatus includes a document holder and a scanner module movably installed in the document holder, A multi-function apparatus may further include the image scanning apparatus. While the scanner module passes over the lower side of a document guide provided between a first glass and a second glass provided at the document holder, spacers installed at opposite ends of the scanner module are moved downward by guide members provided at the document guide, thereby preventing spacer portions provided at an upper end of the respective spacers from being caught by the document guide.
Abstract:
An image reading device comprising: a document placing portion; a conveyor; and a reading unit configured to read an image of the document. The reading unit includes: an image sensor; and a support which supports the image sensor, wherein in the case of reading the image of the document conveyed by the conveyor. The support is to be stopped at a predetermined reading position; a guide; and a driving unit. The reading unit further includes: a release unit configured to release the contact with the guide by separating the support from the guide when the support is moved toward the predetermined reading position; and a contact portion configured to contact with the support separated from the guide by the release unit when the support is moved toward the predetermined reading position.
Abstract:
An optical unit of an image reading device has the center of gravity in a position toward a first sub scanning direction, relative to the middle point of the optical unit in terms of sub scanning directions. An engagement part is provided in a position toward a first main scanning direction relative to a sliding part. A plurality of pairs of pinching parts include a first pair provided in a position toward the first sub scanning direction and a second pair provided in a position toward a second sub scanning direction. Of the two pinching parts in the second pair, the pinching part provided in a position toward the first main scanning direction is biased by a first biasing member toward a rail part side, and the pinching part provided in a position toward a second main scanning direction is not biased by the first biasing member.
Abstract:
A scanner includes a scanning module and a base. The scanning module includes a loading panel and a driving module. The base includes a bottom panel, a sliding portion, and a first resisting tab extending from the bottom panel. A sliding slot is defined in the sliding portion to receive the scanning module. The first resisting tab includes a first tab body extending from the bottom panel and a first resilient absorbing portion connected to the first tab body. The first resilient absorbing portion resists the loading panel to prevent movement of the loading panel when the loading panel moves to a first side of the sliding slot.
Abstract:
A scanning unit is configured to slide along a guide shaft that extends in a predetermined direction. The scanning unit includes a carriage configured to slide along the guide shaft, a bearing which is disposed on a carriage and through which the guide shaft passes, and an elastic deformation allowance mechanism which permits elastic deformation of the external shape of the bearing in the predetermined direction at a predetermined time. For example, a contact image sensor unit includes a box equipped with a contact image sensor. The box has a bearing through which a guide shaft is inserted. The bearing has a pair of bosses, bushings that fit therein, and a coil spring that is disposed between the bushings. The bushings are urged by the coil spring, so that the bushings continually protrude outwards. As the contact image sensor unit slides along the guide shaft, the bushings insert in between the bosses when the bushings abut the wall surface of the frame, so that the bearing is deformed elastically. An image reading device may include a scanning unit.
Abstract:
Provided is an image processing device capable of efficiently executing index printing based on motion picture data. A printer having a function of index-printing a plurality of frame images based on motion picture data, includes: a setting unit for setting the number of thumbnail images in the index printing; a first designation unit for designating motion picture data; a first printing unit for selecting and printing, upon dividing the designated motion picture data into a plurality of partial motion picture data according to the set number of the thumbnail images, a frame image for each of the divided partial motion picture data; a second designation unit for designating specific partial motion picture data from the plurality of partial motion picture data; and a second printing unit for selecting and printing, upon additionally dividing the designated specific partial motion picture data into a plurality of partial motion picture data according to the set number of the thumbnail images, a frame image for each of the divided partial motion picture data
Abstract:
A linear guiding apparatus at least has a shaft and a shaft holding apparatus. The shaft holding apparatus is adapted to slide along the shaft. The shaft holding apparatus includes a body, an elastic member and an adjusting member. The body has a V-shape supporting surface, wherein the V-shape supporting surface is along the axis direction of the shaft and supports on outer edge of the shaft. The elastic member is mounted on the body, wherein the elastic member is elastically contacted the outer edge of the shaft, and the shaft is clipped between the elastic member and the V-shape supporting surface. The adjusting member is mounted on the body and contacted the elastic member, wherein the adjusting member is utilized to adjust the position of the elastic member. Therefore, a shaft of any diameter can be clipped between the elastic member and the V-shape supporting surface.
Abstract:
The present invention provides for an optical scanning apparatus having a scanner body and a self-propelled light bar assembly supported within the scanner body. In one example the scanning apparatus further includes a drive track supported within the scanner body, and the light bar assembly includes a drive wheel in contact with the drive track. This configuration allows the drive wheel to propel the light bar assembly with respect to the scanner body. In a second example the scanner has a scanner body and a magnet-track portion of a linear electric motor fixedly supported within the scanner body. The light bar assembly includes a slider portion of a linear electric motor, and the light bar assembly is supported in the scanner body to place the magnet-track portion in proximity to the slider portion to thereby allow the light bar assembly to be driven along the magnet-track portion.
