<p>PURPOSE:To detect only the moving amount of either an X-direction or a Y- direction by operating switches as necessary, selecting and outputting the moving amount of either the X-direction or the Y-direction. CONSTITUTION:In a state that the switches 8 and 9 are not operated, the moving quantities of the X-direction and the Y-direction are detected by an X-direction sensor and a Y-direction sensor 4, the outputs of respective sensors 3 and 4 are inputted to an interface 5 and outputted to a central processing unit as information. When the switch 8 in the X-direction is depressed, for example, which has been transmitted to one end of an X-direction gate 6, the signal of a logic '1' is inverted to a logic '0', the X-direction gate 6 operates, and the output of the X-direction sensor 3 is prevented. Consequently, only the output of the Y-direction is outputted from the interface 5 as moving amount information in the Y-direction.</p> |
