Patent ID: 8190038

Claim:
An image formation apparatus including a plurality of detection sections performing status detection of the apparatus and a plurality of driver sections driving the apparatus, the image formation apparatus comprising: a first set of signal lines including a detection data line through which a detection result from the plurality of detection sections is transmitted, a first identifying signal line through which a first identifying signal to identify one of the plurality of detection sections is transmitted, and a first valid period signal line through which a first period signal to determine a valid period of the first identifying signal on the first identifying signal line and to determine a valid period of data on the detection data line is transmitted; a detection identification control section which identifies a detection section in question according to the first identifying signal, and determines data on the detection data line as valid data for the detection section in question; a second set of signal lines including a drive control data line through which a drive control signal is transmitted to the plurality of driver sections, a second identifying signal line through which a second identifying signal to have identified one driver section from the plurality of driver section is transmitted, and a second valid period signal line through which a second period signal to determine a valid period of the second identifying signal on the second identifying signal line and to determine a valid period of data on the drive control data line is transmitted; a driver identification control section which identifies a driver section in question according to the second identifying signal, and determines data on the driver control data line as valid data for the driver section in question; and an image formation control section which controls the detection identification control section and the driver identification control section.
