1. A control apparatus comprising:
- a first display unit;
a second display unit configured to include a plurality of display elements;
a first control unit configured to include an output terminal for outputting a signal to a first signal line corresponding to each of the plural display elements;
a second control unit configured to include a first input terminal for inputting data output from the output terminal through the first signal line corresponding to each output terminal of the first control unit and a second input terminal for inputting a command signal which gives instructions to input the data from the first signal line, and configured to control display on the first display unit based on the data.

Abstract
A signal line used in a key matrix is shared between a signal line used in a first display unit and a signal line used in a second display unit. Two types of periodical pulse signals are superimposed on a level signal which indicates data displayed on the second display unit. One type is a pulse signal for detecting key input and another type is a pulse signal which indicates data displayed on the first display unit.
