<P>PROBLEM TO BE SOLVED: To reduce a quantity of terminals for connecting a device with apparatus. <P>SOLUTION: The device includes: a driving element; a control circuit which controls the driving element; a first information forming section which forms first information; a second information forming section which forms second information; an output terminal for the information; and a first element board and a second element board respectively including a switch for selecting either one of the selective connection of the output terminal with the first and second information forming sections, or setting the output terminal under a high impedance state conforming to selection information which is input from the outside. The device also includes: a first input section which is connected with the first element board through a first signal line and inputs the first selection information; a second input section which is connected with the second element board through a second signal line, and inputs the second selection information; and an output section which is connected with the information which is respectively output from the first and second element boards through a common signal line. <P>COPYRIGHT: (C)2012,JPO&INPIT |
