According to one embodiment, a paper conveyance apparatus includes: a paper feed section on which paper is placed; a first roller configured to be arranged at the upstream side of a reading position where the paper is read to convey the paper at a first speed; a second roller configured to be arranged between the first roller and the paper feed section to convey the paper at a second speed faster than the first speed; a motor; a fourth roller configured to be arranged between the first roller and the reading position and driven by the motor to convey the paper to the reading position at the first speed; and a transmission section configured to always transmit a rotation driving force of the motor to the first roller and the fourth roller.

A medium-discharging device includes: a device main body including a medium-discharging section that discharges a medium; a medium-receiving tray that receives the medium discharged by the medium-discharging section; and a pressing member that is configured to be attached to and detached from to the device main body and presses the medium discharged by the medium-discharging section against the medium-receiving tray in a state in which the pressing member is attached to the device main body, in which the pressing member is configured to switch, in the state in which the pressing member is attached to the device main body, between a first state in which the pressing member comes into contact with the medium-receiving tray and a second state in which the pressing member retreats upward so as to be apart from the medium-receiving tray.

According to one embodiment, an image forming apparatus includes a setting unit configured to apply a setting selected from at least a decolorable recording agent including a decolorable color material and a non-decolorable recording agent including a non-decolorable color material, for a sheet feeding cassette; and a display unit configured to display sheet feeding cassettes whose settings match a user-selected recording agent differently from sheet feeding cassettes whose settings do not match the user-selected recording agent.

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.

An image reading device includes a transport section that transports a recording medium along a transport path, an image reading section that is provided on one side of the transport path and reads an image formed on the recording medium transported through the transport path, a rotary body that is rotatably provided and is provided on a side opposite to an installation side of the image reading section across the transport path, and a protruding portion that is provided at least at one end portion out of one end portion and the other end portion of the rotary body in an axial direction and protrudes from the rotary body toward the image reading section side.

A motor drive control device includes: a deceleration start position calculating unit that calculates a deceleration start position indicating an address at which a pulse period is stored, the pulse period being equal to or larger than a pulse period at the time of forced stopping and closest to the pulse period at the time of forced stopping among the pulse periods included in a driving information; a stop pulse number calculating unit that calculates the number of pulses required for stopping the motor at an exciting position; and a driving control unit that outputs a total number of pulses of a counted number of pulses and the number of pulses from the deceleration start position until the motor is stopped in forcibly stopping the motor, and outputs a shortage of the number of pulses required for stopping the motor calculated by the stop pulse number calculating unit.

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.

A conveying mechanism sequentially conveys document sheets placed on a document sheet placing portion to a document sheet discharge portion through an image reading position at which an image is read from each of the document sheets. The document sheet discharge portion is provided below the document sheet placing portion. A raising and lowering mechanism raises and lowers the document sheet placing portion. A first determination processing portion determines whether or not any of the document sheets is placed on the document sheet placing portion. A second determination processing portion determines whether or not any of the document sheets is placed on the document sheet discharge portion. A raising and lowering processing portion controls raising and lowering operations by the raising and lowering mechanism on the basis of results of determinations made by the first determination processing portion and the second determination processing portion.
