Abstract: In a case that a bare chip has been detected as being defective from among bare chips, a good chip is mounted to the rear surface of the surface wherein the bare chips are provided to a semiconductor module substrate so that a QFC pin of the bare chip is fixed at the ground potential (GND). Thereby, the bare chip stops the output of a signal to the input/output terminals or the input of a signal from the input/output terminals. As a result, the good chip outputs an electrical signal to the input/output terminals or an electrical signal is inputted from the input/output terminals. Thereby, a semiconductor module is gained that can be repaired even in the case that a defective chip is detected after the chip has been molded into a mold resin.

Abstract: In a conventional color printer, especially an in-line type full color image forming apparatus, an aberration of optical axes caused by distortions of structures affect a performance of an image forming as a tilt aberration in a printed image. Accordingly, in a conventional color printer, distortions have to be prevented by strengthening rigidity of machine structures or parts of the machine. However, fine adjustment or assembling to strengthen rigidity generally causes an increase in cost and requires time-consuming adjustment. An apparatus in the present invention provides advantages of high accuracy and strengthened structure without increasing cost.
