In an image processing system, an image reading apparatus determines whether an error occurs on a read image that is an image read by an image sensor, and generates and transmits data including the read image and error information that is information indicating presence or absence of occurrence of the error, and an image processing apparatus receives the data and performs, on the read image, image processing corresponding to the presence or absence of occurrence of the error, based on the error information.

A sheet feeding device includes a stacking tray for stacking a sheet; a sheet detector for detecting presence/absence of the sheet on the stacking tray; a feeder for feeding the sheet detected by the sheet detector; an LED, provided adjacent to the sheet stacked on the stacking tray, for emitting light; a display, provided substantially in parallel with an optical axis of the LED, for being illuminated by the light emitted from the LED; a reflector, provided opposed to the display portion, for reflecting and scattering the light emitted by the LED, toward the display; and a controller for controlling emission of the light of the LED on the basis of a signal outputted by the sheet detector.

An information processing apparatus includes a setting reception section and a posture acquisition section. The information processing apparatus outputs a scan setting to an image reading apparatus including a main body having a plurality of postures. The main body reads a document according to the scan setting. The setting reception section is configured to display a setting item included in the scan setting on a display portion and receive a change in a setting content shown in the setting item. The posture acquisition section acquires posture information indicating the posture of the main body from the image reading apparatus. The setting reception section switches the setting item displayed on the display portion to the setting content according to the posture when the posture indicated by the posture information is switched.

A document reading apparatus includes a scanner, an input device receiving an input of a width and length, and a processor configured to scan an area specified based on the input length and generate a first image, generate a second image by removing a part of the first image so that a width of the second image is equal to or greater than the input width, detect a background or non-background area in the second image, determine whether the input is appropriate based on whether all sides of an area specified based on the input width and length overlap the background area or none of the sides overlaps the non-background area on the second image, and when the input is appropriate, output a third image in which the background area is removed or the non-background area is extracted from the second image.

A control unit of an image reading apparatus determines, based on results of detection of an original document by a plurality of second detecting units, whether the original document will pass a position at which the original document is to be detected by a first detecting unit that is located downstream of the second detecting units and upstream of a reading unit. When it is determined that the original document will not pass a position at which the original document is to be detected by the first detecting unit, the control unit determines a timing for reading the original document by using the reading unit, relative to a time point at which the original document is detected by the second detecting units. The control unit causes the reading unit to read the original document at the determined reading timing.

A power storage device includes power storage cells that includes a positive electrode, a negative electrode, a separator, and an accommodation chamber accommodating a liquid electrolyte in a liquid-tight manner. The power storage device includes a cell stack in which the power storage cells are stacked in series. A side surface of the cell stack is covered with a seal portion made of a plastic. A terminal positive electrode current collector and a terminal negative electrode current collector located in the outermost layer of the cell stack are made of a high thermal conductivity material having a thermal conductivity greater than or equal to 100 W/(m.Math.K). The power storage device includes a positive electrode cooling unit, which cools the terminal positive electrode current collector, and a negative electrode cooling unit, which cools the terminal negative electrode current collector. The liquid electrolyte contains an ester compound.

An image forming system includes: a processing part that invalidates an eye mark formed on a medium by processing the eye mark; and a hardware processor that controls the processing part, wherein the hardware processor determines whether an image formed at a position corresponding to a position of the eye mark on the medium has an abnormality, and when the image has an abnormality, the hardware processor causes the processing part to process the eye mark corresponding to the image.

A reading method guidance apparatus includes a receiving unit, an acquisition unit, and a guidance unit. The receiving unit receives a document size that is a size of a document as a reading target. The acquisition unit acquires an image of at least a partial area in the document. The guidance unit provides an operator with guidance about a reading procedure when the document is read by a first reading apparatus in plural batches, using a feature amount obtained from the acquired image, the received document size, and a readable size that is a size of an area readable by the first reading apparatus.

An information processing apparatus includes a processor. The processor is configured to perform a process. The process includes disassembling each of multiple first data sets in units of pages if a combination in the first data set is improper. The multiple first data sets are obtained by reading and sorting out multiple document sets each containing multiple pages of documents. The process also includes reassembling an adequate combination as a second data set if a page group obtained as a result of the disassembling includes the adequate combination.

A reading apparatus includes a transport unit, a multi-feed detection unit, a reading unit, and a controller. When a multi-feed of the document is detected by the multi-feed detection unit, the controller multi-feeds causes the transport unit to discharge, downstream of the transport path, a multi-fed document for which the multi-feed is detected and then temporarily stops the transport, stores multi-fed page information indicating a page number of the multi-fed document, restarts the transport after the temporary stop, and after the reading unit reads a remaining document whose page succeeds a page of the multi-fed document, performs a re-reading process including the transporting and the reading of the multi-fed document, respectively, and inserts, based on the multi-fed page information, second read data acquired by the reading in the re-reading process into first read data acquired by the reading completed before the re-reading process.
