摘要： The present image forming apparatus includes a first control unit and a second control unit driven by built-in clock oscillators to realize the distributed control. The first control unit generates, using a first timer driven by the built-in clock oscillator of the first control unit, a pulse signal corresponding to a predetermined clock rate and outputs the pulse signal to the second control unit. The second control unit measures, using a second timer driven by the built-in clock oscillator of the second control unit, a pulse width of the pulse signal outputted from the first control unit, and calculates a correction coefficient using reference pulse width corresponding to the predetermined clock rate and the measured pulse width. The processing unit processes using the calculated correction coefficient.

摘要： A first lower layer control unit controls a conveyance unit, that conveys the medium in a first conveyance section of a conveyance path. A second lower layer control unit controls a conveyance unit, that conveys the medium in a second conveyance section located downstream of the first conveyance section. An upper layer control unit determines whether the medium is at a position where both the first lower layer control unit and the second lower layer control unit engage with conveyance control of the medium, instructs the first lower layer control unit and the second lower layer control unit to operate in synchronization with each other when the medium is at the position, and instructs the second lower layer control unit to operate asynchronously to the first lower layer control unit when the medium is not at the position.

摘要： This invention provides an image forming apparatus that suppresses a control error between CPUs when the CPUs operate in cooperation with each other in distributed control by the CPUs. To accomplish this, the image forming apparatus utilizes a distributed control system. Respective CPUs measure time interval concerning image formation processing using their built-in clock oscillators, and perform operations in cooperation with each other. Correction coefficients are calculated based on the time interval measured by the respective CPUs to correct a measurement error generated by the operation an error of the respective clock oscillators. Clock count values each indicating a timing to drive a load is corrected based on the correction coefficients.
