FILE MANAGEMENT PROGRAM AND FILE MANAGEMENT SYSTEM, FOR OUTPUTTING TARGET FILE, AND INFORMATION FILE CONTAINING INFORMATION LINKED WITH TARGET FILE, TO EXTERNAL DEVICE
A file management system includes a communication device and a control device. The control device acts as a file manager, a file outputter, an information file generator, and a file merger. The file manager manages various files. The file outputter outputs a file based on a target file among the various files, to outside of the computer via the communication device. The information file generator generates an information file which is a document file containing information linked with the target file. The file merger generates a merged target file, by merging the information file with the target file, when the target file is of a specific file format. The file outputter outputs, when the file merger generates the merged target file, the merged target file to outside of the computer via the communication device, as the file based on the target file.

Image processing apparatus, image forming apparatus, and image processing method for efficiently performing image processing of image forming apparatus in time divisional manner
Provided is an image processing apparatus that efficiently performs time-divisional image processing tasks related to image formation of an image forming apparatus. A time division determination unit configured to determine and switch which of divided work items to execute based on execution time in a condition where at least one first task to be processed at a specific pace and at least one second task to be processed at best effort are respectively divides into smaller work items. A task execution unit executes the work item switched by the time division determination unit in a time division. This work item uses something as like first band data and second band data.
In an image formation device, a driven gear is coupled to a far end portion in a unit inserting and withdrawing direction of a rotary fixing member or a rotary pressure member of a fixing unit. A driving gear is provided in a far end portion of a fixing unit housing part and engages with the driven gear when the fixing unit is housed in the fixing unit housing part. The driving gear and the driven gear are formed so that a transmission force transmitted from the driving gear to the driven gear in a mutual engagement position has a component so directed as to horizontally press the fixing unit against columns making a pair. The fixing unit as housed in the fixing unit housing part is pressed by the transmission force against the columns and positioned in a direction orthogonal to the unit inserting and withdrawing direction.
A document conveying device according to the present disclosure includes a sheet feeding tray, a discharge tray, a feeding roller, a first lifting mechanism, a conveying mechanism, a support member and a second mechanism. On the sheet feeding tray, a document is stacked. The discharge tray is provided below the sheet feeding tray. The feeding roller feeds the document on the sheet feeding tray. The first lifting mechanism supports both end portions of the sheet feeding tray in a width direction intersecting a conveying direction of the document, and lifts and lowers the sheet feeding tray such that an upper surface of the document comes in contact with the feeding roller. The support member supports the sheet feeding feed tray on an upstream side of the first lifting mechanism in the conveying direction. The second lifting mechanism lifts and lowers the support member in synchronization with the sheet feeding tray.
B65H 1/14 - Supports or magazines for piles from which articles are to be separated with means for advancing the pile to present the articles to a separating device comprising positively-acting mechanical devices
A heating unit urging member urges a first support body of a heating unit toward a second support body of a fixing unit with elastic force. The heating unit urging member brings the first support body into contact with the second support body and brings the second support body into contact with two struts. An interlocking mechanism moves the heating unit along a direction in which the heating unit and the fixing unit are arranged, in conjunction with movement of an operation portion. When the operation portion moves from a first position to a second position, the interlocking mechanism moves the first support body from a reference position where the first support body is in contact with the second support body to a retracted position where the first support body is separated from the second support body.
A guide unit holding portion is formed at a position between two struts in a longitudinal direction of a fixing unit. When a main cover portion rotates from an open position to a closed position, a supported portion of a swing guide unit moves from a position where the supported portion is separated from the guide unit holding portion to a position where the supported portion is in contact with the guide unit holding portion. Further, the supported portion slides on the guide unit holding portion. When the supported portion slides on the guide unit holding portion, the swing guide unit is swung upward, and then held at a target position by the guide unit holding portion.
This folding container (100) has a lower frame (1), an upper frame (2), side plates (3, 4) and a pair of lid plates (7). The upper frame (2) has the same configuration as the outer edge of the lower frame (1), and is in the form of a frame element that has an opposing pair of first lateral sides (2b), and a pair of second lateral sides (2c) linking the ends of the first lateral sides (2b). The pair of lid plates (7) have at least one linking arm (70) formed in a section at which the pair of second lateral faces (2c) are linked. The linking arm (70) is rotatably supported on a linking shaft (9) provided at an interval from one or more lid-plate supports (20) formed on the second lateral faces (2c). The linking arm (70) has hollow cylindrical bearing parts (70a-70c) into which the linking shaft (9) is slidably inserted. Formed on the outer peripheral surface of at least one of the bearing parts (70a-70c) are a pair of engaging projections (77) constituted by a first engaging projection (77a), and a second engaging projection (77b) the circumferential-direction location of which differs from that of the first engaging projection (77a). The lid-plate support (20) is provided with an angle-limiting part (20a) with which the first engaging projection (77a) and the second engaging projection (77b) engage.
