Abstract: A functional block has a normal operation mode and a test mode. An external signal terminal receives an operation inhibition signal which is activated to inhibit the normal operation of the functional block. An external clock terminal receives an external clock. A test mode control circuit shifts the functional block from the normal operation mode to the test mode while the operation inhibition signal is in an activated state and the test mode control circuit is receiving the external clock. Accordingly, the semiconductor testing apparatus inputs the operation inhibition signal in a fixed activated state to the external signal terminal and inputs the external clock to the external clock terminal, thereby shifting the functional block to the test mode.

Abstract: A laser printer includes a photoconductor unit and a developer unit which are removable from a housing of the printer. A fixing device having a heating roller and a cover covering the heating roller is arranged in the housing adjacent to the photoconductor unit. The cover includes an upper wall and a plurality of ribs formed on the outer surface of the upper wall to prevent an operator's hand from directly touching the outer surface of the cover. That rib which is closest to the photoconductor unit is formed to prevent the operator's fingers from being caught by the fixing-device-side end portion of the photoconductor unit.
