る。First, in step 1-1, it is judged whether or not a voltage difference of a predetermined value or more has occurred in the conductive rubber. Here, the instructor touches the conductive rubber with, for example, a finger to input the direction. When the indicator touches the conductive rubber, the resistance value of the conductive rubber changes and the voltage also changes. Here, when the voltage shows a difference of a predetermined value or more compared with the normal voltage, it is determined that the instructor has an input intention (FIG. 4). Then, the coordinates of a place where a voltage difference of a predetermined value or more is generated are recorded (step 1-2), and the coordinates are used as the starting point coordinates. Figure 4
As shown in, the coordinates of the place where the voltage difference occurs (X in the figure) are
It is obtained by representing the conductive rubber surface with the X axis and the Y axis.

内に指を離したか否かを判断する。その判断は所定値以
上の電圧差の有無に基づき判断する。It should be noted that the input instruction is made in one unit from when the instructor puts his / her finger on the conductive rubber until it is released. In other words, once the finger is placed on the conductive rubber and then the finger is released from the conductive rubber, one instruction ends. Direction input is based on the direction from where the finger is placed to where the finger is released. In step 1-3, it is determined whether the instructor has lifted the finger from the conductive rubber within a predetermined time. The judgment is made based on the presence / absence of a voltage difference of a predetermined value or more.

6に至る。The predetermined time referred to here is a time sufficient for the instructor to place a finger on the conductive rubber and then give a direction instruction, and is usually several seconds. Here, the predetermined time is, for example, 5 seconds. In step 1-3, when there is no voltage difference equal to or more than the predetermined value before the predetermined time of 5 seconds elapses, that is, the indicator removes the finger from the conductive rubber before the predetermined time elapses.
If one input instruction is completed here, step 1-
Up to 6.

告燈は消えない(ステップ1−5)。On the contrary, if there is a voltage difference above the predetermined value before the predetermined time elapses in step 1-3, that is, if the indicator does not release the finger from the conductive rubber during the predetermined time, step 1- Up to 4. As described above, the predetermined time of 5 seconds is sufficient as the time for inputting the direction after placing the finger on the conductive rubber, and it is generally considered that the instruction is completed within this predetermined time. That is, from step 1-3 to step 1
-6. However, if the indicator does not let go of the finger and there is a voltage difference of a predetermined value or more even after the elapse of a predetermined time of 5 seconds, it is considered that there is no intention of input, and for example, a warning light installed on the side of the conductive rubber It blinks to inform the instructor that the instruction is invalid (step 1-4). In addition, when the voltage difference above the specified value does not exist for the warning light,
That is, when the instructor removes the finger from the finger conductive rubber, the finger disappears and the process returns to step 1-1. On the contrary, the warning light does not go off unless the instructor releases the finger (step 1-5).

の意図する方向及び距離とするものである。At step 1-6, the end point coordinates are stored. The term “end point coordinates” as used herein refers to the coordinates of the location where the instructor releases his finger from the conductive rubber before the elapse of a predetermined time. next,
The distance between the start point coordinates and the end point coordinates is measured, and it is determined whether or not the distance is equal to or greater than a predetermined value (step 1-7). If the distance between the two coordinates is not more than the specified value, it means that the indicator did not move the place where the finger was placed on the conductive rubber, or even if it did, it was only a small distance from the original position. In this case, it is determined that there is no intention of inputting the distance, and the process returns to step 1-1. Note that the movement of the finger from the start point coordinates to the end point coordinates may not be a perfect straight line but may be curved, but the coordinates of the finger at the intermediate point are not taken into consideration, and a straight line is drawn between the two coordinates. Then, the direction and distance intended by the instructor are set.

Based on the vector, the character or the like displayed on the display is moved from the position a to the position b in FIG. 2 around the blinking portion of the cursor (step 1-9).
