Abstract

PURPOSE:To perform interruption and data transfer processing with relatively simple constitution by generating an ineterruption signal provided with a pulse break period, and by transferring data during the break period. CONSTITUTION:When a horizontal synchronizing signal is applied, an interruption signal generator 7 which generates a double-speed synchronizing signal generates 16 pulses having intervals of 15 horizontal lines in one field and an interruption signal f1 provided with a break period having intervals of 38 horizontal lines and 37 horizontal lines in an odd-numbered and an even-numbered field eight before a vertical synchronizing signal. During the periods of 37 and 38 horizontal lines, data is transferred between a microcomputer 1 for mechanics control and a microcom- puter 2 for fetching key inputs. On the other hand, while a timer counter 9 counts the interruption pulses having the intervals of 15 horizontal lines, the shift clock generator 13 of the computer 2 is made ineffective through a transfer request generator 10 to perform interruption processing as to whether a kick pulse is generated or not. Therefore, the relatively simple constitution performs interruption and data transfer processing securely.
