Description of the invention (i) [Technical field to which the invention belongs] (Please read the notes on the back before filling out this page) The invention relates to the position of the cursor on the display surface of a display device of a mobile personal computer, for example The optical multi-directional input device used for outputting the indication signal used by the image sensor and the image processing. As a multi-directional input device for moving the position of a cursor connected to the display surface of a computer indicating display device via a cable, conventionally, the amount of movement of a ball moving on a plane is converted into X γ axis coordinates to obtain an X axis coordinate signal The Y-axis coordinate signal is called a multi-directional input device for a mouse. Therefore, the mouse-type ball is a contact type that moves on a flat surface. As a result, dust may contaminate the mouse, which may cause malfunction. Therefore, maintenance of the mouse including the sweep of the ball must be performed. From the above situation, a non-contact multi-directional input device for obtaining the X Y-axis coordinate signal optically without using a ball is disclosed in, for example, Japanese Patent Laid-Open Publication No. 3 1 2/9 3. As a multi-directional input device of this non-contact method, an image processing coordinate conversion integrated circuit is used to detect the movement amount and direction, and the detection result is converted into X Y axis coordinate signals and output.

The matte film 91 can be, for example, ordinary photocopying paper or cloth. In short, as long as it has irregular irregularities, the thickness can also be formed on one side of the magnetic material membrane 92. can. The magnetic material film 9 2 can be obtained in a thickness that is as strong as the operation panel 9. For example, an iron plate having a thickness of 1 m m or less and 0 · 1 m m or more can be used. The protective film 9 3 is used as a magnetic material film 9 2 for rust prevention when an iron plate is used, and may be, for example, a nickel plating layer. In this example, the permanent magnet 4 is embedded in a circular recessed portion that is held on the facing surface of the printed circuit board 5 formed in the annular flange portion 31 of the lens member 3. In this example, four permanent magnets 4 are provided at equal intervals. The magnetic material diaphragm 92 of the operating plate 9 by the permanent magnet 4 is magnetically attracted and held on the case 10. Although the attractive operation system 9 does not fall off from the housing 10, the operation panel 9 is placed on the operation surface PS, that is, the ring flange portion 31 and the cover portion 2 of the lens member 3 in the illustrated example. The surface formed on the outside becomes easy to move with a finger. The operation surface PS is preferably a smooth surface from the viewpoint of operability. The diameter of the operating plate 9 is an embodiment, and the diameter of the operating surface PS is about 1/2. The light reflected by the light-emitting diode 8 in the light-emitting state is irradiated to the rough surface of the operation panel 9 through the transparent lens holding portion 32, and the image of the surface is imaged on the image through the lens 3 3 and the light guide portion 71.

Every moment 'image sensor 7 2 imaged on image processing coordinate transformation integrated circuit 7 ° image processing coordinate transformation integrated circuit 7 will identify and calculate the imaging pattern of image sensor 72 2 such as per second It is implemented at a high speed of 1500 times. The content of the identification and calculation of this imaging pattern is a comparison of the imaging pattern in front of the imaging pattern with the current imaging pattern in the specific micro-field of the image sensor, and the related arithmetic processing is performed on the movement direction and amount of the imaging pattern. This recognition calculation process is performed on all areas of the image sensor. The X-axis coordinate signal and the Y-axis coordinate signal are obtained based on the moving direction and the movement amount of the imaging pattern, and are sent to a computer via a cable 5 2 connected to the printed circuit board 5, for example. Pressing, the operating power for the light emitting diode 8 and the image processing coordinate conversion integrated circuit 7 is supplied through the cable 52. However, the range in which the operating panel 9 is moved on the operating surface PS to move the cursor in a certain direction is, in this example, a maximum of approximately the diameter range of the operating panel 9. Therefore, if you want to move the cursor in its direction again, it may be as follows. For example, in FIG. 3, the operation panel 9 is moved from the state of (1) to the direction of the arrow A1, and changed to the state of (2). The operation panel 9 is separated from the lens 33 and becomes not imaged in the image processing coordinate transformation. When the state of the image sensor of the integrated circuit 7 is maintained, the cursor position at that time is maintained, that is, the conventional mouse using the trackball has lifted the mouse from the pad surface to a state where the cursor movement is stopped.

Description of the invention (8) Leave from the lens 3 3 In the state, the center of the lens 3 3 is about half a turn, such as (3) state operation panel 9 is to move the lens 3 3 in the direction of the original arrow A 1 and move the operation panel in the direction of arrow A 1 9. Initially, the lens 3 3 is blocked by the operation panel 9. The state of being placed on the mat surface becomes the same. Therefore, when the operation panel 9 is moved in the direction of the arrow A1, the cursor is moved in the same direction as the cursor and restarted. That is, if the image processing coordinate conversion integrated circuit 7 cannot detect the image of the operation panel 9 moved by the operation panel 9, it will be constituted to stop the output of the X-axis coordinate signal and the γ-axis coordinate signal. As shown in FIG. 6, the annular protrusion 22 and the housing 10 may be integrally formed on the periphery of the operation surface PS to facilitate the operation and use of the operation panel 9. That is, for example, when the cursor is continuously and repeatedly moved in the same direction, the movement of the operation panel 9 is restricted by the annular protrusion 22, and from this state, the operation panel 9 is guided along the annular protrusion 2 and the operation panel 9 is restored. In the original state, you can move the cursor in the same direction. Due to the existence of the ring-shaped protrusion 22, the operation panel 9 may not fall off due to the operation of the finger, and if it is necessary to restore the state when the operation is repeated in the same direction, the lens 3 3 is blocked and the cursor is restarted. There is no danger of moving the cursor in a direction other than the destination. In the above-mentioned embodiment, since the permanent magnet 4 does not directly contact the operation panel 9, that is, when the operation surface P S is entirely composed of a resin material, the operation surface P S can be made into a smooth surface and become a good operability. When this multi-directional input device is mounted on a keyboard or the like, the usability is better when the operation surface PS of the housing 10 and the opposite surface are made flat.
