A display system has a display device, a display control device, and a laser emitting device. The display device has a display part that displays information on a display screen and a laser detection part having a plurality of optical sensors arranged in the vicinity of the display screen of the display part to detect a laser beam that has reached the display screen. The laser emitting device has an instruction input part that inputs an instruction with respect to the displayed information and a laser output part that outputs the laser beam including output information corresponding to the inputted instruction. The display control device has a position calculation part that calculates a position of the display screen irradiated with the laser beam based on positions of the optical sensors that have detected the laser beam, a received information acquiring part that acquires the output information included in the laser beam detected by the optical sensors and a display control part that controls a display of the information displayed on the display part, based on the position calculated by the position calculation part and the acquired output information.

The image forming apparatus includes an image forming portion that synthetically prints image data and ID image data specific to a user on a recording paper, a paper discharge tray that discharges and accumulates the recording papers, and an ID image reading portion that reads the ID images of the recording papers accumulated in the paper discharge tray, and notifies an external device specified by a user corresponding to the read ID image that the recording papers in the paper discharge tray must be removed. The image forming apparatus includes an output condition setting portion that sets output conditions of the recording papers, and the image forming portion prints the image data on a recording paper and the ID image data on an edge of the recording paper in accordance with the output conditions set by the output condition setting portion.

Image forming apparatus

A management server is connected to an MFP and a client PC through LAN. The management server includes a leaving information acquiring portion that acquires leaving information related to recording paper sheets left unremoved for each print job accepted by the MFP, a leaving information count portion that counts the acquired leaving information for each user, and a warning portion that transmits warning information for prompting a user not to leave a recording paper sheet. The leaving information count portion counts the number of print jobs associated with the detection of the recording paper sheets left unremoved for each time zone based on the leaving detection time and the user ID from the leaving information acquiring portion, and when accepting a print job from a client PC, the warning portion transmits warning information to the client PC for a user having the counted number not less than a predetermined number.
