An image reading apparatus includes a conveying unit configured to convey a document, a reading unit configured to read an image on the conveyed document, a measurement unit configured to measure a distance from an upper portion of a sheet feeding port for the document to an upper surface of the document, and a control unit configured to, according to the distance measured by the measurement unit, suspend the conveyance of the document by the conveying unit. According to a user operation for reading again the document of which the reading is suspended by the control unit, the conveying unit conveys the document and the reading unit reads the image on the document, and while the document of which the conveyance is suspended is conveyed again, the control unit does not suspend the conveyance of the document based on the distance measured by the measurement unit.

An image forming apparatus having a plurality of sheet feeding cassettes includes a display device; and a controller circuit including: a display control unit configured to generate information to be displayed on the display device, the information including a sheet feeding cassette selection region and a first recording agent selection region; and a setting unit configured to apply a recording agent setting for each of the sheet feeding cassettes based on a selection made in the first recording agent selection region among at least a decolorable recording agent including a decolorable color material and a non-decolorable recording agent including a non-decolorable color material. The display control unit is further configured to generate for display on the display device a list of the sheet feeding cassettes along with the recording agent setting for each of the sheet feeding cassettes.

A user interface of a printer displays instructions to use the printer's document scanner for scanning a sheet of print media (of a stack of print media being added to the paper drawer) in response to a drawer sensor detecting the opening of the paper drawer. The document scanner generates an electronic image of the sheet of print media from the scanning of the sheet of print media. The processor evaluates the electronic image of the sheet of print media to identify the media type and color of the stack of print media being added to the paper drawer. For example, this is done by evaluating the size, color characteristic, transparency, and reflection characteristic of the electronic image of the sheet of print media. Then, the electronic memory records that the paper drawer contains the stack of print media having a specific media type and color.

An elastic body portion includes an inner circumferential portion and an outer circumferential portion which serves as an outer circumferential side with respect to the inner circumferential portion and a space portion between the inner circumferential portion and the outer circumferential portion, and a plurality of joining portions which join the inner circumferential portion and the outer circumferential portion to each other in the space portion, in which at least a portion of each of the joining portions has a curved shape, and in which the joining portions are each joined to the inner circumferential portion and the outer circumferential portion such that connecting portions between the joining portions and the inner circumferential portion and connecting portions between the joining portions and the outer circumferential portion do not form acute angles in the space portion.

An image reading device includes a loading section, a reader, and a document feeder. The loading section receives loading of a document and an identification medium. The reader reads the document and the identification medium. The document feeder conveys the document to the reader. The loading section includes a second contact glass and a medium restriction section. The second contact glass receives loading of the identification medium. The medium restriction section restricts a position of the identification medium loaded on the second contact glass. The document being conveyed by the document feeder has opposite end portions and a central portion therebetween. The opposite end portions respectively include opposite ends of the document in a direction perpendicular to a conveyance direction of the document. Only the central portion, among the opposite end portions and the central portion, of the document comes in contact with the medium restriction section.

An image forming apparatus having a plurality of sheet feeding cassettes includes a display device; and a controller circuit including: a display control unit configured to generate information to be displayed on the display device, the information including a sheet feeding cassette selection region and a first recording agent selection region; and a setting unit configured to apply a recording agent setting for each of the sheet feeding cassettes based on a selection made in the first recording agent selection region among at least a decolorable recording agent including a decolorable color material and a non-decolorable recording agent including a non-decolorable color material. The display control unit is further configured to generate for display on the display device a list of the sheet feeding cassettes along with the recording agent setting for each of the sheet feeding cassettes.

An image reading apparatus includes a medium mounting portion configured to mount a medium; a feeding means configured to feed a medium from the medium mounting portion; at least one edge guide each configured to regulate a corresponding one of at least one medium width direction edge of the medium having been mounted on the medium mounting portion; a reading means configured to read the medium and disposed on a further downstream side than the at least one edge guide in the medium feeding direction; and at least one medium detection means configured to detect the medium and disposed on a further downstream side than the at least one edge guide in the medium feeding direction and further outside in the medium width direction than at least one edge regulation position for the edge regulation by the at least one edge guide.

An image reading apparatus is provided with an identification information reading unit (reading unit, NFC reader, and identification information acquisition unit) which acquires identification information by reading the identification information from a section to be read at which identifiable identification information is recorded for each individual carrier sheet and which is provided at a joining section of the carrier sheet in which two transparent sheets for pinching an original document are joined at a portion of a peripheral edge portion; and a processor which performs a process which is associated with the identification information read by the identification information reading unit.
