Abstract: There is described a management system, which makes it possible to cope with a plurality of communication methods without complicating the system configuration. The system includes a first managed apparatus, a second managed apparatus and a management apparatus. The management apparatus includes: a first data processing section to conduct a conversion processing between management data and common data having such a format that conforms with the first communication method and that is available for the second communication method; and a second data processing section to conduct another conversion processing between the common data and communication data having such a format that conforms with the second communication method. Further, the management apparatus employs the common data to conduct the data communication with the first managed apparatus, while employs the communication data to conduct the data communication with the second managed apparatus.

Abstract: A control method for a non-contact communication apparatus communicating information to an external device in a non-contact state is provided. The control method includes the steps of stopping an operation of a control circuit after the control circuit performs a predetermined control operation when processing operations relating to the writing and reading of information is to be executed, and executing a predetermined process by an execution circuit which is scheduled to operate next under control by a logical circuit with the control circuit kept stopped when the supply voltage reaches a predetermined value with the result that a load is applied to the supply power supplied from outside.

Abstract: An image forming machine such as a copying machine and a printer for forming an image on a recording medium with plural laser beams. The image forming machine includes an image reader for reading an original image and for simultaneously generating image signals corresponding to the original image; plural laser beam generators for writing the image on the recording medium according to the image signals; an index signal generating circuit for generating plural index signals each of which initiates a respective one of the plural laser beam generators to write the image; and a control circuit for controlling a reading operation of the image reader. In the image forming machine, the control circuit initiates the reading operation of the image reader according to one of the plural index signals.
