Latest Patents
Asakura's latest patents include a "Control device for an image forming apparatus" and a "Bias power source controller for an image forming apparatus." The control device for a copier detects errors in the drive system and drives a photoconductive element. It incorporates a motor and utilizes output from a toner sensor that responds to the density of the toner image formed on the photoconductive element. This device checks for errors in the drive system by computing output data from the toner sensor when the photoconductive element is rotated and when it is in a halted mode. The bias power source controller is designed to control a bias power source associated with a developing unit of an electrophotographic copier. This controller allows for variable bias voltage levels to adjust image density. It includes a central processing unit with a built-in timer/event counter that delivers a trigger pulse signal to activate the power source.
