When the mode flag is the touch input only mode, the mode flag is changed to the auto mode and set to the auto mode (normal mode) (step S46). When the mode flag is the auto mode, the mode flag is changed to the pen input only mode and set to the pen input only mode (step S47). When the pen mode is ON, the pen input is canceled until the auto mode ON or the pen input dedicated mode ON is executed by changing the mode flag.

In the present embodiment, the pen tip of the input pen and the pen tail are turned upside down to provide a pen input only mode,
The mode is switched in the order of the touch input only mode and the auto mode, but it is also possible to change the order and stop the mode selection such as the touch mode. On the other hand, in step S41, the tilt angle E. of the input pen of the event information is set. If a is smaller than the threshold value Ma, the process proceeds to step S48 to clear the event flag (Event = 0). Then, the pen input processing (step S50) and the touch input processing (step S5) are performed according to the state of the mode flag.
1) and an automatic input process (step S52).

When the mode flag is the touch input only mode, the pen input is ignored and only the touch input is made valid (step S51). When the mode flag is the pen input only mode, the touch input is ignored and only the pen input is made valid (step S50). Further, when the mode flag is the auto mode, a touch or a pen input becomes possible depending on a touched state (step S52).

In this automatic input processing, the above-mentioned FIGS.
Is included. Next, an algorithm for grasping a state where the pen is stationary and realizing energy saving will be described. FIG. 11 illustrates this. After the event occurs, it is determined in step S61 whether or not the coordinate position information of the input pen 6 is the same. That is, it is compared whether the detected current position information (E.Px, E.Py) is equal to the position information (LastX, LastY) detected immediately before.

As a result of this comparison, when the current position information and the immediately preceding position information are equal, the state continues for a predetermined time or more, and there is no movement of the input pen 6 (Last t> T).
(Step S62), an energy saving mode is set (Step S63). If the current position information and the immediately preceding position information are different in step S61, step S6
The process proceeds to step S4, and if it is the energy saving mode at that time, the energy saving mode is canceled (step S65).
