PURPOSE: To eliminate malfunction, by dislocating sheet members to carry out illumination and operation so as not to be ovelapped each other, and carrying out sheet processing for the first time when two among plural number of mark members arranged in the edge part are detected, in a control device connected to a terminal device so as to carry out monitoring, restraint and allocation on a load.

CONSTITUTION: Illumination load correspondence switches 62 are arrayed in a rank shape on an operation panel 30, and adjacent to these switches 62, illumination load areas in which display elements 63 are arrayed are provided. Adjacent to these areas, an operation switch group is also arrayed, and guide grooves positioned in a boundary of a switch area for illumination and operation are provide in the upper/lower edge parts on the panel 30, and along these, blocking parts having frame members 30A and 30B are provided. When name plates are installed on the panel 30 by constituting in this way, whether a sheet setting mark is in a normal position or not is detected, and when it is not in the normal position, position error notice processing is carried out, and when it is in the normal position, the following mark position is detected, and the respective switches are operated.
