Abstract: A centralized control system capable of remote controlling terminal devices such as a copying machine or automatic vending machine by using communication lines. The system displays information identifying the terminal devices which have not transmitted the information to a central unit after predetermined time. Further, the system is provided with a back-up power source for backing up a memory storing the information to be transmitted and an IC for clocking the present time. The information stored in the memory is to be transmitted when the power is supplied again in the case where the transmission has not been carried out at the predetermined time because the power source for the terminal device was shut off. Moreover, the system judges, in the case where an image forming apparatus is adapted as a terminal device, whether the image forming apparatus has recovered from trouble condition to normal condition by judging whether a copy paper is actually discharged.

Abstract: This invention realizes synthesis of an image of an original document (an original image) with a separate image composed of a row of characters. The possibility that the original image and the separate image will overlap each other when the original image is printed on a sheet is precluded by the present invention using a procedure which comprises comparing the size of the sheet with the size of the original image (size of sheet> size of original image) and shifting (adjusting) the position for printing the original image or, when necessary, further contracting the original image or the separate image so that the separate image may be contained by way of synthesis in the part of a margin of the sheet appearing as the difference between the size of the sheet and the size of the original image prior to the printing of the original image on the sheet.

Abstract: In a digital copying machine, a document image is read and the document image is reproduced on a paper. If a document has a size which does not limit a direction of document on a platen For reading the document image, the document type of portrait or landscape is decided according to the direction of document on the platen. If a user sets a document type, the setting by the user may have priority than the decision according to the document direction. If a document has a size which can be set only along a specified direction for reading the document image, it is requested for a user to set the document direction (portrait document or a landscape document). Then, for example, a margin can be set suitably according to the document type.
