Abstract

PURPOSE: To input coordinate data on a data tablet by an information input unit that uses the data tablet, by making an interruption by detecting a stylus pen being depressed.
CONSTITUTION: A signal of each coordinate point generated by pressing stylus pen 2 against data tablet 1 is detected by signal detecting circuit 8 and coordinate calculating circuit 12 calculates coordinates. On detecting stylus pen 2 being pressed down, switch detecting circuit 7 interrupts processor 15. As a result, when a transfer request is sent from processor 15 to transfer control circuit 10, data buffer 13 is controlled to fetch and transfer the coordinate information of coordinate calculating circuit 12 to processor 15.
