Abstract: In an image forming apparatus, even when the image forming positions of the plural light beams of the exposure optical system vary, there can be formed an image without any shifting between image forming positions. In response to a print reference signal from a timing controller, an output controller causes a storage to output image data of a first raster to a second temporary memory and image data of a second raster to a first temporary memory. The output controller supplies the second and first temporary memories with data output reference signals respectively indicating points of timing when a predetermined period of time lapses after each of the laser beams respectively of first and second exposing units enters a sensor disposed at a reference position. According to the output reference signals, the image data is outputted to the first and second exposing units such that an image is formed at timing corresponding to image forming positions of the laser beams.

Abstract: A car remote control system utilizing a signal in the form of electromagnetic wave or infrared ray called `keyless entry`. When receiving a predetermined wake-up signal, an MPU is once operated even when the received input signal is a noise signal to perform only judging operation of whether or not the input signal is normal. Only when judging that the input signal is a normal wake-up signal, the MPU controllably causes an electronic circuit to be shifted to a usual operation mode. When judging that the input signal is the noise signal prior to full input of the tuner signal, the MPU immediately shifts to a sleep mode. Thereby current consumption of an electronic control circuit can be suppressed.
