[Problems of the prior art discovered by the present inventors]
Currently, when drawing a circle, the circle is drawn on the software. When measuring the distance between a certain point, the distance between the two points is measured on software. However, in order to perform such an operation, a certain degree of computer skill is required, which causes inconvenience for elderly people who prefer old-fashioned operations and those who are not accustomed to computers.

Despite the above, no compass or divider has been developed that is familiar to older people who prefer old-fashioned operations and those who are new to computers. The inventors of the present invention examined whether the compass and divider used on the paper can be used in the state-of-the-art "touch panel", and surprisingly, the extremely simple configuration has been used on the paper to date. We have come to discover that the compass and divider used above can be used in the state-of-the-art "touch panel". That is, according to the present invention of the present inventors, in the field of nautical charts and electronic blackboards, by using an actual compass and divider as an input device or the like in a touch panel type liquid crystal display device or the like, analog operability has been conventionally achieved. While maintaining, it is possible to enable drawing and distance measurement in the current touch panel liquid crystal display device.

[Embodiment 1]
[Structure of compass 10]
In this embodiment, it is a schematic diagram for explaining a compass for drawing a circle on a touch panel type display device. The compass 10 has a grip portion 11 for the user to grip and two legs (first leg 12 and second leg 13) extending from the grip portion 11 (FIGS. 1 and 2). As a general rule, the grip portion 11 has a cylindrical shape. In general, gripping means that it can be held by a hand or a finger, but in the present specification, it suffices if it is configured so that it can be pinched by the thumb and index finger of the right hand.

The angle θ formed by the first leg 12 and the second leg 13 is freely variable around the grip portion 11. That is, the legs can be opened at any angle. In the present invention, the range of possible values of θ is from 0 degrees to 180 degrees, but it does not necessarily have to be configured to open up to 180 degrees.

The tip 14 of the first leg 12 is provided with a pen tip used as a sensor unit for detecting a contact state with the display device, and the pen tip is a conductive material. In the drawing, a dish-shaped pen tip is illustrated and described. In the present invention, since the conductive resin is used as a substitute for graphite used in the conventional compass, it is possible to enable input in a touch panel type display device with a simple configuration.

A resin is arranged on the tip portion 15 of the second leg 13 so as to serve as a fulcrum compass leg. Normally, the compass is provided with a compass fulcrum needle, but in the present invention, a silicon tube (for example, φ3 mm, inner diameter 1 mm) is inserted into the compass fulcrum needle, and a gap portion between the compass fulcrum needle and the tube is inserted. Is filled with a silicone resin. The hardness of the silicon tube is preferably about 60 to 70.

[How to use Compass 10]
When drawing a circle with the compass 10, the tip of the second leg 13 is placed at the center point of the circle to be drawn, and the tip 14 of the first leg 12 orbits on the circumference of the circle to be drawn. Move. At this time, since the legs of the compass are rotatably connected, θ is variable. This makes it possible to draw circles of various sizes.

In addition, the pressure generated by the force that holds down the compass when a person draws a circle causes the silicon tube to elastically deform. Since the repulsive force due to this elastic deformation and the frictional force generated on the adhesive surface extending to the tip of the tube act, it is possible to draw a circle without deviating from the center point. The tip of the silicon tube may have a convex shape such as a sphere or a flat shape. In the case of a convex shape, a silicon tube may be used to form the convex surface, or a silicon resin may be used to form the convex surface.

Furthermore, since the silicon tube is inserted into the compass fulcrum needle, the center of the circle can be accurately grasped by looking at the tip of the compass fulcrum needle, and the needle tip can be placed accurately at the center point. can. When a non-conductive material is used for the needle tip, the touch panel does not respond. Therefore, when the needle tip is placed at the center point, there is no possibility that the touch panel will malfunction.

[Operation method on display device]
As the display device, a known touch panel type display device such as a touch panel type EL display device and a liquid crystal display device can be generally applied. As a method of use on the display device, when the tips of the two legs 12 and 13 of the compass 10 are brought into contact with each other, the tip 14 of the legs 12 is a pen tip for a touch panel, so that the sensor of the display device can be used. The presence of an object that operates and touches the display device is detected. When the drawing mode or the like is activated and the compass is rotated in a circular motion, information about the locus of the tip portion 14 is transmitted from the input unit related to the touch panel of the display device to the storage unit, and in some cases, as a locus to the display device. Is displayed. At this time, by predetermining the conductivity of the conductor connected to the tip portion 14 to a predetermined value, an object having a conductivity within the first predetermined range is a compass, and an object within the second predetermined range is a compass. It is possible to distinguish the type of input device from the divider, etc. The display device may be a nautical chart display device or an electronic blackboard. Further, the compass is not generally sized to be gripped by the thumb and index finger, but may be a large sized compass for an electronic blackboard.

[Structure of divider 20]
It is a schematic diagram for demonstrating the divider 20 for measuring a distance in one Embodiment of this invention. The divider 20 has a grip portion 21 for the user to grip and two legs (first leg 12 and second leg 13) extending from the grip portion 21 (FIG. 3). As a general rule, the grip portion 21 has a cylindrical shape. In general, gripping means that it can be held by a hand or a finger, but in the present specification, it suffices if it is configured so that it can be pinched by the thumb and index finger of the right hand.

The angle θ formed by the first leg 22 and the second leg 23 is freely variable around the grip portion 21. That is, the legs can be opened at any angle. In the present invention, the range of possible values of θ is from 0 degrees to 180 degrees, but it does not necessarily have to be configured to open up to 180 degrees.

The tip 24 of the first leg 22 and the tip 25 of the second leg may be provided with a conductive material as a sensor portion for detecting a contact state with the display device. In the drawings, in this embodiment, a conductive resin is used as an alternative to graphite used in a conventional compass. Since it has such a configuration, in the present invention, it is possible to enable input in a touch panel type display device with a simple configuration.

Resin is arranged on the tip 24 of the second leg 23 and the tip 25 of the second leg to serve as a fulcrum. Normally, the divider is provided with a fulcrum needle for the divider, but in the present invention, a silicon tube (for example, φ3 mm, inner diameter 1 mm) is inserted into the fulcrum needle, and the gap between the fulcrum needle and the tube is filled. Fills with silicone resin. The hardness of the silicon tube is preferably about 60 to 70.

[How to use the divider 20]
When measuring the distance with the divider 20, the tip portion of the second leg 13 is placed at a predetermined start position, the tip portion 14 of the first leg 12 is touched to a place in the direction in which the distance is to be measured, and then the tip portion 14 is touched. After rotating the second leg 13 around the tip 14 as the center of rotation, touch the tip 15 of the second leg to the place where you want to measure the distance, and continue to rotate the divider one or more times. Measure the distance from the number of times. At this time, since the legs of the compass are rotatably connected, θ is variable. This makes it possible to measure distances of various sizes.

Further, since the resin body is arranged as described above, the silicon tube is elastically deformed by the pressure generated when a person holds down the divider. Since the repulsive force due to this elastic deformation and the frictional force generated on the adhesive surface extending to the tip of the tube work, the divider can be used without deviating from the center point, so that the distance can be measured accurately. The tip of the silicon tube may have a convex shape such as a sphere or a flat shape. In the case of a convex shape, a silicon tube may be used to form the convex surface, or a silicon resin may be used to form the convex surface.

Further, since the silicon tube is inserted into the fulcrum needle, the starting point can be accurately grasped and the distance can be measured accurately by looking at the tip of the fulcrum needle. When a non-conductive material is used for the needle tip, the touch panel does not respond. Therefore, when the needle tip is placed at the center point, there is no possibility that the touch panel will malfunction. On the other hand, when a conductive material is used for the needle tip, the distance between the two points can be recognized by the touch panel. Therefore, it is possible to display the distance between two points on the software while using the hard divider.

[Modification example]
The needle portion 26 may be present in the resin arranged at the tip portion 25 of the divider, or the needle portion 26 in which the conductive resin is transparently configured and embedded may be visible from the outside ( FIG. 4). With this configuration, the position pointed by the divider can be easily understood by looking at the tip of the needle portion 26, so that the distance can be measured accurately. The tip portion 24 may also be provided with a needle portion in the same manner.
