Abstract: To enable highly accurate fold processing by properly moving a sheet that has been subjected to fold processing. In a sheet processing apparatus that that performs fold processing in such a manner as to apply first fold processing to a sheet and then apply second fold processing at a position different from a fold line formed in the first fold processing so as to make one end of the sheet folded in the first fold processing lie inside the folded sheet, the first fold processing is applied to a sheet conveyed to an intermediate tray by a fold roller pair and, when a regulating stopper is moved to move the folded sheet that has been subjected to the first fold processing to a predetermined position of the intermediate tray, the folded sheet is gripped by a grip unit.

Abstract: At the point in time when it is determined that the number of sheets constituting one sheet bundle exceeds the maximum number of sheets that can be crimp-bound, a sheet bundle that has already been shifted to a crimp-binding position is discharged to a crimp-binding discharge position without being subjected to crimp-binding. Thereafter, succeeding sheets are shifted as a bundle to the crimp-binding position and discharged to the crimp-binding discharge position without being subjected to crimp-binding.

Abstract: A post-processing apparatus includes a sheet support device, a pair of side edge regulation members that engage in sheet opposite side edges on the sheet support device, and a shift device configured to shift a position of each of the side edge regulation members, and thereby causing the members to perform carry operation to shift the sheet on the sheet support device, wherein in executing the carry operation, the shift device sandwiches the sheet by the pair of side edge regulation members, and thereby makes a state in which pressure is applied to the sheet to execute.

Abstract: A method of reading document image data and transferring the image data to a data reception apparatus, includes setting memory areas for storing the image data in a data storage section and setting a reading condition, upon receipt of a scan start command; transmitting the scan start command for instructing the scanner apparatus to start operations; instructing the scanner apparatus to transmit the image data to a transfer data storage section; transferring the image data in the transfer data storage section to the data storage section in response to a data transferring request command; transmitting a document end signal to the data storage section; executing feeding of subsequent document sheets, without transmitting another scan start command; determining whether distance from a rear end is a predetermined length or more, and an available space is a predetermined amount or more; and controlling a feeding section based on determination results.

Abstract: An image reading system includes a scanner apparatus and a data reception apparatus. The data reception apparatus has a receiving section receiving image data transferred from the scanner apparatus, a received data storage section storing the image data received in the receiving section, and a driver program executing section executing a driver program for operating the scanner apparatus to transmit a scan start command. The scanner apparatus has a feeding section feeding an original document sheet to a predetermined reading position, a reading sensor reading an image of the original document sheet fed by the feeding section, a transfer data storage section storing image data from the reading sensor, a transfer section transferring the image data stored in the transfer data storage section to the data reception apparatus, and a scanner control section controlling the feeding section and the reading sensor.

Abstract: In a method of reading document image data scanned by a scanner apparatus, upon receipt of a scan start command from the data reception apparatus, memory areas are set for storing image data in a data storage section of the data reception apparatus to set a reading condition; a scan start command is transmitted to start reading operations; the scanner apparatus is instructed to transmit the image data, to receive and store the image data in the data storage section; the image data is transferred to the data reception apparatus in response to a data transferring request command from a host apparatus; a document end signal received from the scanner apparatus is transmitted to the data storage section; and subsequent original document sheets are fed based on available status of the data storage section, without transmitting another scan start command.

Abstract: It is an object of the invention to provide an image reading system enabling a plurality of image original document sheets to be consecutively read at high speed. A scanner apparatus has a feeding section that feeds an original document sheet to a predetermined reading position, a reading sensor that reads an image of the original document sheet fed by the feeding section, a transfer data storage section that stores image data from the reading sensor, a transfer section that transfers the image data stored in the transfer data storage section to the data reception apparatus, and a scanner control section that controls the feeding section and the reading sensor.
