摘要： An image forming apparatus is provided with a host computer, a copier, and a printer operable in response to instructions from the host computer. Upon receipt of image information from the host computer, the printer forms an image on a first sheet whereas the copier forms on a second sheet an image of a document placed on a document platform. The apparatus is further provided with a document conveying device for conveying to the document platform the first sheet as a document on which the image has been formed by the printer. The apparatus has at least two drive modes: a single drive mode at which all the transcripts are prepared by sole use of the printer and a double drive mode at which the first sheet having the image formed by the printer is conveyed by the document conveying device so that the rest of transcripts are prepared by the copier.

摘要： There is disclosed a facsimile apparatus comprising plural keys arranged on an operation panel and a RAM for storing data of destinations and facsimile numbers thereof so as to correspond to respective keys. A network control unit of the facsimile apparatus dials through a communication line the facsimile number stored in the RAM corresponding to pressed one of the plural keys when one of the plural keys is pressed. Further, a printer section reads the data stored in the RAM, and prints the read data on a piece of paper or label in a format suitable for sticking it on an IC card or in the vicinity of each of the plural keys on the operation panel.

摘要： An image filing system which uses, in addition to main document identification data in the form of a keyword assigned to a given document, auxiliary document identification data formulated to be representative of a characterizing portion of the image read from a given document, wherein the image data representative of the whole image read from the document is stored in one data storage area of a memory and the image data representative of the characterizing portion of the image is stored in another data storage area of the memory for use as the auxiliary document identification data. When the documents accessed as a result of the searching on the basis of a keyword or keywords, the auxiliary document identification data is displayed for each of the documents in addition to the keyword or keywords assigned to each of the documents listed on the display. This will help the operator of the system select and call the target document from among the listed documents by referencing the auxiliary document identification data as well as the main document identification data. The auxiliary document identification data is thus useful for distinguishing one document from another or others when the documents have a common keyword as the main document identification data.
