An image recording apparatus includes a feed tray, a feed mechanism feeding a sheet-shaped medium accommodated in the feed tray, and a recording device recording an image on the sheet-shaped medium fed by the feed mechanism. The feed tray includes a first accommodation portion accommodating a roll, in which the sheet-shaped medium is rolled, a pair of side walls interposing the sheet-shaped medium unrolled from the roll in a first direction parallel to an axis of the roll, and a side guide disposed inside the pair of side walls and having an inner-side surface contactable with an edge in the first direction of the first sheet-shaped medium unrolled from the roll. The side guide has a metal portion made of metal, the metal portion forming at least part of the inner-side surface.

Adjustment image data is for use in adjusting imaging operation. The adjustment image data is stored in a storage of an image forming apparatus and read from the storage to form an image on a sheet of paper at the time of adjusting an imaging operation of the image forming apparatus. The adjustment image data includes a single identification mark located in the vicinity of a longitudinal center of the sheet of paper.

A voice operation system includes: an image forming apparatus that forms an image on a recording material; a server that accepts voice information related to an operation on the image forming apparatus, and gives an operation instruction to the image forming apparatus; and a voice input/output device that converts an input voice into voice information, sends the voice information to the server, receives voice information as a response to the voice information related to the operation on the image forming apparatus, and emits a sound of the voice information, wherein the server has a hardware processor that stores information on a part of a function or configuration of the image forming apparatus, and the server determines executability of an operation associated with voice information transmitted from the voice input/output device, and causes the image forming apparatus to execute determination of executability of an operation that is not determinable.

An image reading apparatus acquires first control data regarding generation of first rectangular image data that includes a whole of a document area corresponding to a document within a reading area of read image data. The image reading apparatus acquires second control data regarding generation of second rectangular image data that does not include a background area not corresponding to the document within the reading area of the read image data and includes at least a part of the document area.

An image processing apparatus having a reading device to read an image from a sheet includes one or more controllers to perform operations. One image is read from one sheet by using the reading device. Edge detection processing is executed on the one image. At least one pair of edges is determined from among a plurality of edges based on information of the plurality of edges detected in the edge detection processing and size information of the one sheet.

An instruction receiving unit receives a return instruction to return a deleted image IMD deleted from an album page to the album page. A return processing unit executes a return process of returning the deleted image IMD to the album page in response to the return instruction. An extracting unit executes an extraction process of extracting, from among a plurality of deleted images IMD, an identical-attribute image IMS which is a deleted image IMD whose attribute is identical to an attribute of an image IM present in the album page at a current position of scroll display. A list display processing unit executes a list display process of displaying, together with the album page, a list of identical-attribute images IMS.

A method and system for rendering a correlation mark, can involve determining a combined path of a foreground comprising a first layer based on a first correlation pattern and a background comprising a second layer based on a second correlation pattern. The size of the second layer of the second layer can be calculated based on a trade off between how well the second layer hides a correlation effect and a readability of the second layer. The combined path can be filled with variable data at the size of the second layer at a selected color or a third correlation pattern to produce a two-layer correlation mark having a variable data hiding layer for rendering on or through a recording medium.

An image reading apparatus acquires first control data regarding generation of first rectangular image data that includes a whole of a document area corresponding to a document within a reading area of read image data. The image reading apparatus acquires second control data regarding generation of second rectangular image data that does not include a background area not corresponding to the document within the reading area of the read image data and includes at least a part of the document area.

An image reading apparatus includes a platen on which a document is to be placed, an image sensor configured to read an image of the document on the platen, an opening/closing member configured to cover and uncover the platen, a document pressing layer disposed on a surface of the opening/closing member and configured to press the document on the plate when the opening/closing member covers the platen, elastic layers located between the document pressing layer and the opening/closing member and spaced apart from each other on a surface of the document pressing layer, and connection layers connecting the elastic layers to the opening/closing member. An area of the elastic layer is larger than an area of the connection layer.
