An image forming apparatus includes a document reader, a storage for storing image data, an image output unit and a control unit. The control unit includes: a function setup controller for setting up the image output conditions of output images; and a control-unit side controller having a function of displaying a function setup screen corresponding to the function setup controller, on a display panel. The function setup controller has an additional input mode having a function of reading documents a multiple number of times to form multiple sheaves of documents. The additional input mode includes: an individual setup function of setting up individual image output conditions for each sheaf of documents and an all-in setup function of setting up identical image output conditions for all sheaves of documents. When the additional input mode is set up, the control unit-side controller offers a display of a setup change suggestion of the image output conditions for the next input on the display screen at the stage where the first image data input has been completed.

In accordance with an embodiment, an image reading apparatus sets a scan speed corresponding to an operating speed input by the operation panel. The image reading apparatus executes a scan job at the set scan speed. In addition, the image reading apparatus updates a scan counter in accordance with the number of pages of an image read at the set scan speed.

A document reading device that is capable of selectively designating a document reading process includes a sound output unit that gives notification of information needed for a document reading process that has been selected and a notification control unit that controls output from the sound output unit. When a specific document reading process has been selected, the notification control unit exercises control so that in a case where a device state of the document reading device is not the specific device state, notification information that prompts for the specific device state is outputted by the sound output unit after a predetermined period of time has elapsed since the specific document reading process was selected and so that in a case where the device state of the document reading device is the specific device state, notification information whose content prompts for the specific device state is not outputted by the sound output unit.

An image forming apparatus includes: a signal output unit configured to output a signal in response to a user operation; a reading unit configured to read a document and generate image data having a first resolution or a second resolution lower than the first resolution; a recording unit configured to form an image on a recording medium; and a controller configured to control the reading unit and the recording unit and execute: (a) primary preparation operation start processing of, when a signal is output, controlling the reading unit so as to start a first preparation operation or a second preparation operation; (b) determination processing of determining; (c) secondary preparation operation start processing and/or reading processing; (d) decision processing of deciding the continuous number of recording copies; and (e) recording processing of causing the recording unit to form the image on the recording medium.

An image reading device that connects to a network, the image reading device exemplarily including: an operation panel that has a display; a document reader that generates scan data by reading a document placed on a document plate when a scan instruction specifying a save destination is received from an information terminal via the network; and a controller. The controller may cause display of the save destination on the display, which may be ready to receive a panel operation via the operation panel to execute a process for transmitting the scan data to the save destination, and upon receiving the panel operation, may execute the process for transmitting the scan data to the save destination.

The present disclosure pertains to an image reading device that may include an image reader, an operation detector, a correction parameter adjuster, an entry detector, and a document reading controller. The image reader may read an image on a document. The operation detector may detect an operation indicating a start of a reading of the image on the document. The correction parameter adjuster may perform adjustment of a correction parameter. The entry detector may detect entry of a document reading instruction including a reading condition. The document reading controller may check for completion of the adjustment of the correction parameter for the reading condition. If the adjustment of the correction parameter is not completed, the document reading controller may instruct the correction parameter adjuster to perform adjustment of an uncompleted correction parameter and instruct the image reader to read the image.

An image reading device includes reading devices arranged in a main scanning direction perpendicular to a sub-scanning direction, position reference members each including a reference pattern for correcting relative positions of pixels in each of the reading devices or relative positions of the reading devices, and circuitry. The reference members move in the sub-scanning direction relative to the reading devices, and include first reference members for correcting the relative positions of the reading devices and second reference members for correcting the relative positions of the pixels in each of the reading devices. While switching between the first reference members and the second reference members, the circuitry calculates a correction value for a deviation of the pixels in each of the reading devices and a correction value for a deviation of the reading devices based on a result of reading of the reference members.

A document reading device includes an image reading part, a document conveying part, an operation display part, an overlap detecting part and a controlling part. The overlap detecting part detects overlap of a document conveyed to the image reading part. When the overlap detecting part detects the overlap, if an overlap image corresponding to the overlap in the image data obtained by the image reading part matches with a predetermined preservation image, the controlling part decides that the overlap is not double feed to continue the scanning operation. If the overlap image does not match with the predetermined preservation image, the controlling part decides that the overlap is the double feed, stops the scanning operation, and, if user judgement that the overlap is not the double feed is inputted in accordance with operation of the operation display part, stores the preservation image on the basis of the overlap image.

An image reading apparatus comprising: an original reading unit configured to read an image of each of multiple originals placed on an original table in batch by a batch-scan; a cropping unit configured to crop an image of each original from an entire image which is read by the batch-scan; an image output unit configured to output a cropped image of each original; and a control unit configured to control the original reading unit, the cropping unit, and the image output unit, wherein the control unit makes the original reading unit read the image by a batch-scan in which an image density of an edge of each original is supposed to be higher than an image density of a reading-area outside of the original, and an area to be cropped is determined on the basis of a difference in the image density between the edge and the reading-area outside of the original.

It is possible to read a document at an optimal speed according to an operation mode selected by a user while improving productivity at a low cost, without forcing the user to perform a complicated operation for changing a document reading speed. A method for controlling a reading unit to read a document with a first reading resolution in a case where a reading resolution is the first reading resolution, to read a document with a second reading resolution in a case where the reading resolution is the second reading resolution smaller than the first reading resolution and a predetermined mode is not set, and to read a document with the first reading resolution in a case where the reading resolution is the second reading resolution smaller than the first reading resolution and the predetermined mode is set.
