A sheet feed device includes a sheet storage portion, a first regulation portion, a feed portion, and a second regulation portion. The sheet storage portion is attached to an apparatus main body in a detachable manner. A sheet is stored in the sheet storage portion. The first regulation portion stands on a bottom surface of the sheet storage portion and regulates a position of the sheet in a predetermined width direction by externally abutting on a first side of the sheet in the width direction. The feed portion is provided in the apparatus main body and feeds the sheet in a feed direction perpendicular to the width direction. The second regulation portion is provided in the apparatus main body and regulates a position of the sheet by externally abutting on the first side at a downstream of the first regulation portion in the feed direction.

A sheet storage device includes a sheet positioning member that is movable in a first direction, and positions a sheet by abutting on a side end portion of the sheet at a side in the first direction. The sheet positioning member includes a moving body, an abutting portion, a first and a second biasing member, and a bias removing portion. The moving body is configured to move in the first direction. The abutting portion is supported by the moving body to be movable in the first direction and configured to abut on the side end portion when the sheet positioning member positions the sheet. The first biasing member biases the abutting portion toward the side end portion. The second biasing member biases the abutting portion against a biasing force of the first biasing member. The bias removing portion removes a bias applied by the second biasing member.

An image forming apparatus includes a feeding unit, a detection unit provided downstream of the feeding unit, a measurement unit that measures a measured time from the start of conveyance of a recording material to the detection of the recording material, and a determination unit that performs renewal determination for determining whether the feeding unit has been replaced with a new feeding unit. Thus, replacement of the feeding unit with a new feeding unit can automatically be detected.

An image forming system includes an image forming apparatus having an apparatus main body, a sheet feeding cassette, a manual bypass tray, an opening/closing detection part and a sheet feeding source setting part. The apparatus main body has an input part to which a printing instruction is input. The manual bypass tray is displaced into an open posture and into a close posture. The sheet feeding source setting part sets the sheet feeding cassette or the manual bypass tray as a sheet feeding source. When the opening/closing detection part detects that the manual bypass tray is displaced from the close posture to the open posture and the printing instruction is input to the input part, regardless of the sheet feeding source input to the input part, the sheet feeding source setting part sets the manual bypass tray as the sheet feeding source.

The disclosure is directed to a printer device including a printer body, a paper correction module, and a processor. The printer body has a media feed path. The printer body detects a width of the paper to output a paper size signal. The paper correction module is installed in the media feed path. The paper correction module includes two paper guiding arms and an actuating mechanism. The actuating mechanism is capable of driving the two paper guiding arms to approach or move away from each other. The processor is electrically connected with the actuating mechanism. After the processor receives the paper size signal, the actuating mechanism is controlled to space the two paper guiding arms with a preset interval.

A sheet conveying device includes a sheet feed tray. The sheet feed tray includes a first guide and a second guide. The first guide has a first end portion. The first end portion has a first area located in a central portion in a width direction, and a second area located closer to one end in the width direction than the first area. The first end portion is inclined such that the first area is downstream of the second area in the sheet conveying direction. The second guide has an upper end portion located downstream of the first end portion of the first guide in the sheet conveying direction and above the first end portion. The upper end portion has a third area located in a central portion in the width direction and a fourth area located closer to an end in the width direction than the third area.

An image forming apparatus includes a control unit and an attachment detection unit to detect attachment of a cassette having a stacking portion that may be lifted by a motor. The control unit drives the motor to start lifting the stacking portion when cassette attachment is detected and stops when the stacked uppermost sheet is detected at a sheet feed position, at which time the presence or absence of the stored sheet is determined based on a detection signal output by a sheet presence/absence detection unit. In a case where there is no change in the detection signal output from the sheet presence/absence detection unit when the attachment of the cassette is detected, the control unit determines that a failure of the sheet presence/absence detection flag occurred.

Disclosed are a cash box and a cash recycling and handling device; the cash box includes a box body, a first cash storage cavity, a second cash storage cavity, a transfer passage, a first switching member and a linkage assembly; a first lifting platform is provided inside the first cash storage cavity, and the first lifting platform is capable of moving back and forth in the preset direction and can be located at a first dispensing position; when the first lifting platform is in the first dispensing position, it is engaged with the linkage assembly to rotate the first switching member to a first position, and when the first lifting platform moves to a first inlet, the linkage assembly rotates the first switching member to a second position.

An image forming apparatus includes an apparatus body that forms an image on a recording material; a drawn-out unit that is provided so as to be drawable from the apparatus body and has a mount region on which the recording material is mounted; and a guide unit that is provided on the drawn-out unit and guides the recording material to a position where the recording material is to be mounted on the mount region. The guide unit has a guide surface that guides an end of the recording material, a hook part that is hooked onto the drawn-out unit and determines a position relative to the drawn-out unit, and a release part that releases the hook part from the drawn-out unit by being operated by a user from a guide surface side.

A supply device configured to supply a medium to a processing unit configured to perform processing on the medium, the supply device including an accommodating unit configured to accommodate a plurality of the media in a state of being stacked therein and a vibration imparting unit configured to contact ends of the plurality of media accommodated in the accommodating unit to impart vibration to the medium.
