A document processing device includes a scanner, a display, a notification unit, and a control unit. The scanner is configured to read a document provided on a document table. The display is configured to display image data of the document read by the scanner. The notification unit is configured to provide a notification warning to indicate that the document has not been removed from the document table. The control unit is configured to detect the document on the document table.

A transportation device transports a document sheet from a feeding tray to an output tray. A first lifting device lifts and lowers the feeding tray. A feeding-tray upperlimit sensor detects that the feeding tray reaches an upperlimit height. An output-tray sheet sensor detects the document sheet on the output tray. Further, the controller at a standby status (a) determines whether a document sheet is on the output tray or not, (b1) if a document sheet is not on the output tray, arranges the feeding tray at a predetermined intermediate position, and (b2) if a document sheet is on the output tray, arranges the feeding tray at a lower position that is a position apart by a predetermined distance from a position of the feeding tray when detecting that the feeding tray reaches the upperlimit height. Here, the lower position is a position higher than the intermediate position.

A document conveying device includes an operation device, a document loading tray, a document detection sensor, a document ejection tray, a feed roller, a document conveying mechanism, an elevating mechanism, and a controller. Upon passage of a first waiting time from when the document detection sensor has detected any sheet of original document on the document loading tray, the controller allows the elevating mechanism to move the document loading tray to a standby position between upper and lower limit positions and stop the tray at the standby position. Upon acceptance of an instruction to read original document through the operation device, the controller allows the feed roller to feed a sheet of original document on the document loading tray, allows the document conveying mechanism to convey the fed sheet to a reading position, and allows the elevating mechanism to move up the document loading tray to the upper limit position.

The information processing apparatus includes a display. The information processing apparatus accepts user operations via a GUI (graphical user interface) displayed on the display. When the service ends, the forgotten item notification screen is displayed on the display. In the forgotten item notification screen, a forgotten item reminder unit is provided for reminding a user who left behind a reminder target item, including the property of the user used in connection with the service. An individual reminder section is provided in a forgotten item reminder unit, to give an individual reminder to prevent the occurrence of leaving behind of each reminder target item, for a first-type item for which retrieval cannot be detected and a second-type item for which retrieval can be detected but which has not been retrieved, from among the reminder target items.
