Latest Patents
One of Yoshino's latest patents is a temperature control method for a fixing device. This innovative method involves controlling the surface temperature of a heat roller within a fixing device by utilizing a thermistor. The thermistor is designed to be in contact with the heat roller during the warm-up operation and in a standby condition, or it can be spaced apart from the heat roller while a copying operation is in progress. The heater is controlled based on the temperature measured when the thermistor is not in contact with the heat roller. This method also includes a correction mode that compares temperatures measured in both contact and non-contact positions of the thermistor. If the temperature difference does not fall within a predetermined range, the method stops energizing the heater, indicating an error has occurred.
Another notable patent is for a paper handling apparatus. This apparatus features multiple bins, a paper positioning device for distributing paper sheets to the bins, and a stapler for stapling the stacked paper sheets. The controller ensures that the paper positioning device continues to position the paper sheets even after they have been stapled by the stapler.
