  • Publication number: 20110132957
    Abstract: A device includes a conveying roller configured to convey a recording medium, a follower roller configured to press the recording medium against the conveying roller, a detector configured to detect a direction of skew of the conveyed recording medium, and a changer configured to change a state of contact between the recording medium and the conveying roller in accordance with a result of the detection by the detector such that a length of a portion of the conveying roller that is in contact with the recording medium in a conveyance direction is larger on a side toward which the recording medium is skewed than on an opposite side.

  • Publication number: 20110125948
    Abstract: In order to control sub-processors in parallel without losing extensibility, an execution control circuit (30), which forms a multi-processor system (1), issues a process command (CMD) to each of sub-processors (20—1 to 20—3) based on a process sequence (SEQ) designated by a main processor (10), and acquires a process status (STS) which indicates an execution result of processing executed by each of the sub-processors (20—1 to 20—3) in accordance with the process command (CMD). An arbiter circuit (40) arbitrates transfer of the process command (CMD) and the process status (STS) between the execution control circuit (30) and each of the sub-processors (20—1 to 20—3).

  • Publication number: 20110097127
    Abstract: In a first step, a sheet is conveyed in a direction, whereby a leading end portion of the sheet is fed to a position between a decurl roller and a decurl pinch roller, which are in positions spaced apart from each other. In a second step, the leading end portion of the sheet is curved and held by causing the decurl pinch roller to come close to or press against the decurl roller. In a third step, the leading end portion of the sheet is withdrawn from between the decurl roller and the decurl pinch roller by conveying the sheet in a direction opposed to the conveying direction. After executing the first to third steps, the sheet is conveyed in the conveying direction through the first step while the sheet is curved by the decurl roller.

  • Publication number: 20100322419
    Abstract: It is possible to improve a radio communication digital baseband processing device including data encryption/decryption so as to prevent processing failure caused by a data rate increase in recent years by increasing the MAC processing speed of data encryption/decryption and realizing the load distribution in a processing device. A data processing device which performs a communication process including data encryption/decryption includes: a control processor which performs calculation of the MAC processing parameter; and MAC processing means which performs MAC data processing including data encryption/decryption. The control processor controls the MAC processing means by a command script continuously describing a combination of a command and parameter accompanying it.

  • Publication number: 20100199006
    Abstract: To provide inter-LSI data synchronized transfer with a transfer throughput satisfying a required performance without causing an operation timing difference of the entire system even when a wiring delay between LSIs varies on an evaluation board and an actual device. A master (LSI1) outputs transfer data and a transfer synchronization clock signal to a slave (LSI2). For the edge of a clock signal used for data output at the master (LSI1), the slave (LSI2) latches input data by using a reverse edge. Moreover, upon data transfer from the slave (LSI2) to the master (LSI1), the master (LSI1) selects a latch timing of input data from a plurality of timings so that the transfer time to an internal circuit of the master (LSI1) side is identical regardless of which latch timing is selected.

  • Publication number: 20100045715
    Abstract: A recording apparatus includes a carriage carrying a recording head and being movably supported, the recording head being configured to eject liquid onto a recording medium, a plurality of driven units to be driven by a drive source that generates a driving force, a transmission-switching mechanism configured to switch between the driven units, a carriage locker configured to prevent and allow movement of the carriage, and a transmission-switching locker configured to prevent and allow switching between the driven units. Movement prevention by the carriage locker and switching prevention by the transmission-switching locker are in synchronicity, and movement allowance by the carriage locker and switching allowance by the transmission-switching locker are in synchronicity.

  • Publication number: 20090206539
    Abstract: A recording apparatus includes a cassette having a stacking region for stacking recording materials mounted to main assembly of the recording apparatus; a feeder for feeding the recording material stacked to the cassette; a sheet discharge portion for sheet discharging the recording material having been subjected to a recording operation; a tray movable between a first position where the recording material is incapable of being discharged from the sheet discharge portion and a second position where the recording material is capable of being discharged from a main assembly of the recording apparatus; a holding portion, disposed on the tray, for holding the recording material discharged when the tray is at the second position; an auxiliary portion disposed on the tray and capable of stacking the recording material with the stacking region when the tray is at the second position.

  • Patent number: 7165133
    Abstract: A multiprocessor system having a plurality of processor elements each of which obtains right to use bus of a first or second shared bus in response to a transfer request for control system data or input/output data and as a master, conducts multiplex-transfer or burst-transfer, in which the processor element outputs a bus request signal for the first shared bus in response to a transfer request for the control system data and as a master, transfers and outputs a selection signal, a control signal and an address signal of a transfer destination and the control system data in one cycle in response to application of a bus grant signal, and is selected as a slave based on the selection signal through the first shared bus to receive input of the control system data and process the data based on the control signal and the address signal.
