摘要:
An improved photographic printer having a source of light such as a laser can produce printed copies from a photoconductive surface. Data representative of the images to be printed can be transformed into intermediate codes which are stored for driving a print controller. A timer can set a predetermined time depending on the length of the paper for the data transformation into the intermediate codes and various elements in the printer can be activated prior to the completion of the transformation, including forwarding copying paper to a predetermined position adjacent the photoconductive surface whereby excessive wear of the printer is prevented and an increased printing speed is achieved.
摘要:
A data communication system for the communication between two different data transmission systems, the SDT system and the RDT system. The SDT system includes a host CPU having an output terminal for repeatedly producing first data in a predetermined sequence of time slots by a number of interruptions taken in each time slot, a bus structure extending from the output terminal of the host CPU for transmitting the data, and a plurality of slave CPUs, each having an input terminal connected to the bus structure for receiving the first data. The RDT system for the data transmission between at least first and second CPUs includes a RAM for storing a command to the second CPU. The first CPU is operative to write the command into the RAM. The first command writing takes place at a first predetermined pulse period in a predetermined sequence of pulses. The second CPU reads the command from the RAM at a second predetermined pulse period. The host CPU in the SDT system is used in common with the first CPU in the RDT system. Also, the sequence of time slots have at least one time slot which is sufficiently long to include the sum of one cycle of the predetermined sequence of pulses and one pulse period for carrying out the data transmission by the second data transmission system within one time slot.

In order to facilitate the designation of a destination of data while allowing the data to be delivered in a processing method desired by a user at the destination, an MFP includes a registration portion to register for each user a processing method for processing data, a destination designation portion to display a user registered in the registration portion in such a manner that the user can be designated as a destination, a data designation portion to designate data to be delivered to the destination designated by the destination designation portion, and a data processing portion to process data by the processing method registered in the registration portion for the user if data whose destination is the user registered in the registration portion has been delivered.
摘要:
An image processing apparatus, which transmits image data to a plurality of addresses via a network, includes a transmission device which transmits the image data to an address in the plurality of addresses, an address setting device which sets at least one of the plurality of addresses, a determining device which determines, with respect to each of the at least one of the plurality of addresses, whether or not to transmit the image data thereto on the basis of an attribute thereof, and a display device which displays a first address among the plurality of addresses to which the determining device determines to transmit the image data, and a second address among them to which the determining device determines not to transmit the image data on the same screen, in different manners from each other.
摘要:
An additional data useful for the management of copies of a document for an image forming apparatus is embedded in a hard copy of the document. The additional data is embedded in an inherent image of a document as discrete dots arranged in a prescribed format. Preferably, the size of each of said discrete dots is not so large as to be recognized easily with naked eyes. The additional data can be embedded in unit of blocks. Further, the density of the discrete dots is different from the density adjacent to the discrete dots. The image data for embedding an additional data can be obtained by reading a document, or by receiving data sent from a computer or read from a floppy disk. An additional data embedded in a hard copy can be extracted from the image data on the hard copy. Further, the production of a copy according to the image data can be controlled according to the extracted additional data. For example, if the additional data means that the source of the hard copy is a secret document, the copying is allowed only for a legitimate user. An additional data is generated for each copy according to the extracted additional data for embedding it in a hard copy to identify each copy. The additional data generated for each copy are compiled and they are used to manage copies of various sources systematically and illegal copies can be traced easily. If the additional data received from a printer is not consistent with the additional data already stored, the printing may be prohibited. A transmitter for transmitting an additional data may be provided in-a document such as a book.
