Publication number: 20040246541Abstract: An original reading section irradiates an original document with light and receives light reflected back from the original document. The said original-reading section obtains first information from the light reflected back from the original document, the first information being information on optical reflection from a non-image area of the original. A plurality of medium trays hold different types of recording media therein. An information storing section stores second information on optical reflection from each of the different types of recording media. A comparing section that compares the first information with the second information to output a comparison result. A medium selecting section selects a medium from the different types of recording media, the medium being selected according to the comparison result. An image forming section prints an image of the original document on the recording medium.Type: ApplicationFiled: June 1, 2004Publication date: December 9, 2004Applicant: Oki Data CorporationInventor: Ryuichi Kohara

Patent number: 6600575Abstract: A clock dividing section receives a system clock and generates and outputs clock signals of two or more types. Selectors select any of the clock signals of two or more types outputted by the clock dividing section and feed it to a printing control block or reading control block. A decision divider monitors operational states of each block and gives control so that a frequency to be supplied to a functional block in an idle state where any operation is not required is lower than that to be supplied to a functional block being in an active state. Power consumption of the whole custom IC can be more reduced compared with a configuration wherein a clock of fixed frequency is constantly supplied to each functional block and a noise can be controlled.Type: GrantFiled: June 28, 1999Date of Patent: July 29, 2003Assignee: Oki Data CorporationInventor: Ryuichi Kohara
