Japanese Patent JPH0630044

B2

PURPOSE:To attain ease of single selection and continuous selection of a menu by providing an automatic repeat discriminating device generating an interruption signal at a specific interval and using the interruption signal as a menu selection signal. CONSTITUTION:A pen 11 is contacted on a face of a tablet 12 to turn on a switch 13, a coordinate position of the pen 11 is detected by a detector 14 and an interruption signal generator 16 generates an interruption signal. When the switch 12 remains unchanged, the next interruption signal is generated after nearly 1sec. The interruption signal is generated at an interval of 0.1sec when the pen 11 detaches from the tablet 12 until the switch 13 is turned off. When the switch 13 is turned off within the 1st 1sec after the switch 13 is turned on, only the 1st one interruption signal is generated. The state of the switch 13 is discriminated by an automatic repeat discriminator 15 to generate the single interruption and continuous interruption signal and every time an interruption signal exists in the CPU18, it processes the detected coordinate.
