Abstract
PURPOSE: To enable to sequentially transmit the data with a minimum number of signal lines, by dividing the identified data such as coordinate data, page data and panel identification data from a multi-item input device into groups with a suitable bit number and transmitting them in group unit according to the request of data transmission of CPU.
CONSTITUTION: The coordinate position data from a coordinate position identifying mechanism 1 which identifies the data arranged in matrix, page data from a page identifying mechanism 2, and book data from a book identifying mechanism 3 are fed to a data selector 4, and the selection of data to be transmitted is made at a counter 6. Further, the input data is divided into three groups, coordinate position data, page data and book data, and when the data request signal from CPU side is input to the counter 6, a signal is transmitted in group unit from the selector 4 according to th request of transmission, the 2nd strobe signal is fed from an AND gate 7 to the transmission side, and the input data of multi-item can sequentially be transmitted on the minimized number of signal lines.
