Patent ID: 7175175

Claim:
A sheet feeding apparatus comprising: a plurality of driving portions to perform sheet feeding; a detecting portion, which detects an abnormality in any one of said plurality of driving portions; an electric current setting portion, which sets an electric current passing through each of said plurality of driving portions; and a controller, which controls said plurality of driving portions, said detecting portion, and said electric current setting portion, wherein when said detecting portion detects an abnormality in any one of said plurality of driving portions, said controller sets a high value of an electric current of said one of said plurality of driving portions at which the abnormality is detected, the high value being within a range, which is not more than a maximum value of a tolerable electric current of said one of said plurality of driving portions at which the abnormality is detected and within a range, which is not more than a total value of electric currents of said plurality of driving portions, and wherein when said detecting portion detects the abnormality in said one of said plurality of driving portions, and when the value of the electric current of said one of said plurality of driving portions at which the abnormality is detected exceeds the maximum value of the tolerable electric current by increasing the value of the electric current, said controller sets a speed of said one of said plurality of driving portions at which the abnormality is detected within a range, which is not less than a minimum value of a rotatable speed, increases a speed of another one of said plurality of driving portions selected in accordance with an order of priorities assigned to said plurality of driving portions within a range, which is not more than a maximum value of a tolerable speed, and increases a set value of the electric current in accordance with a set value of the speed.
