A recording apparatus includes a housing configured to house a recording portion recording an image on a sheet and to have a side including an opening through which the sheet passes, a tray configured to rotate about a rotation shaft, relative to the housing, between a closed position at a first angle for closing the opening and an open position at a second angle for loading the sheet, and an urging mechanism configured to urge the tray toward the closed position when an angle about the rotation shaft of the tray is between the first angle and a third angle and to urge the tray toward the open position when an angle about the rotation shaft of the tray is between the third angle and the second angle. The third angle is an angle between the first angle and the second angle.

A sheet stacking device includes a sheet stacker, an image capturing device, and circuitry. The sheet stacker stacks a sheet. The image capturing device captures an image of a whole face of the sheet stacked in the sheet stacker. The circuitry detects a size of the sheet stacked in the sheet stacker, whether the sheet stacked in the sheet stacker is a last sheet, or whether an image is formed on an image forming face of the sheet, based on image data of the image captured by the image capturing device.

A sheet stacking device is provided with a hopper unit configured to stack a sheet, a feeding unit configured to feed out the sheet to the hopper unit, a distance detection unit configured to detect an inter-sheet distance, in the vertical direction, between a rear end portion of the sheet that is preceding and a tip end portion of the sheet that is subsequent, and an output unit configured to output a behavior stabilization command for the sheet based on the inter-sheet distance.

Disclosed are methods and systems for dispensing a printed document from a printer machine with a dispensing device. For instance, a document being printed out from the printer machine may be monitored for, and a determination that a document is being printed out from the printer machine may be made based on the monitoring. The printed document may be engaged with an arm mechanism of the dispensing device, the printed document may be urged towards a slot of the dispensing device with the arm mechanism, and the printed document may be dispensed out of the slot with the arm mechanism.

A post-processing apparatus that performs post-processing on paper in which an image is formed, the apparatus including: a paper cutter that cuts the paper in which the image is formed; a reader that reads the paper cut by the paper cutter; and a hardware processor that determines whether a cutting position of the paper cut by the paper cutter is good or not based on a read result read by the reader, wherein the hardware processor determines whether the cutting position of the paper in which partial cutting is performed is good or not, the partial cutting being cutting a portion of the paper by the paper cutter.

A reading apparatus includes a reader, a conveyor, motors and a hardware processor. The reader reads a surface of a recording medium with an image formed. The conveyor includes rollers disposed along a conveyance path that passes through a reading area of the reader, and conveys the recording medium being laid across the rollers. The motors rotate the rollers. The hardware processor controls operations of the motors such that the rollers located farther downstream in a conveyance direction of the recording medium rotate faster. As to at least one motor of the motors, the hardware processor switches between and performs a first control to adjust a rotational speed and a second control to adjust a torque, depending on an operating state of the motor.

A printing apparatus includes a container that can accommodate roll paper in which recording paper is wound; a cover for opening and closing the container; a transporter, including a transport motor and a transport roller, that pulls the recording paper from the roll paper and transports the recording paper; a printing section that performs printing on the recording paper at a position facing the transport roller; a first substrate that has a controller controlling the printing section; and a second substrate disposed to intersect the first substrate, in which the transport motor is surrounded by the first substrate, the second substrate, and the container and a shaft of the transport motor is disposed parallel to a shaft of the transport roller.
