摘要:
A semiconductor device includes a chip, a laser element formed on the chip and a heating element formed on the chip. The laser element is driven to emit a laser beam upon light-on of a laser. Upon light-off of a laser, switching is made so that the heating element is driven so as not to emit the laser beam in the normal laser beam emission direction by the laser element.

When a recording medium fed from a sheet feed drive mechanism is detected at a predetermined position, the counting of a loop feed time or the like variably set in accordance with a predetermined sheet feed condition such as the sheet type or particular supplying device is started, and the drive of the sheet feed drive mechanism is controlled by terminating the feeding operation in accordance with a count termination state. A count time of a timer for detecting a feed jam is variably set in accordance with a sheet feed condition such as material of sheet.

An optional apparatus which can be connected to a printer or other optional apparatus includes a communication section for communicating with other apparatus and a control section which executes a command in response to the command received via the communication section; wherein the communication section has a first communication path for receiving a data string from an apparatus on the upstream side in communication and for transmitting the received data string to an apparatus on the downstream side of the communication and a second communication path for receiving a data string received from the apparatus on the downstream side of communication and for transmitting the received data string to the apparatus on the upstream side of the communication; and the control section executes a command in the command string received via the first communication path or the second communication path and loads the data indicating the execution result of the command in the command string.
摘要:
A video controller generates a video signal from image data on the basis of a print instruction, and an engine controller controls a laser scanner in accordance with the generated video signal to record an image on recording paper by an image forming section. A master controller of an optional master unit performs overall control of a variety of optional units, such as a paper-deck optional unit and a sorter optional unit, in dependence upon a control instruction sent from the video controller. Accordingly, it is possible to provide an image recording apparatus to which a wide variety of optional units can be connected freely without raising the cost of the main body of the apparatus.
