Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a cursor magnifier for magnifying a reading point used as a coordinate indicator such as a cursor in a coordinate reading device such as a tablet or digitizer.

[Summary of the idea]

The present invention realizes a simple and inexpensive structure for easily changing the position of the loupe depending on whether or not it is necessary to use the loupe, and for fixing the loupe in two or more positions.

[Conventional technology]

Conventionally, cursor loupes have been designed to change the position of the loupe depending on whether or not it is necessary to use the loupe, and there are two main types: a sliding loupe method and a rotating loupe method.

[Problem that the invention attempts to solve]

With the sliding method, it is difficult to manage the sliding friction, and the frictional force increases, reducing operability. Also, the structure of the parts that fix the slide shaft and the fixing part of the loupe are complicated, and the overall structure is large. The problem is that it is difficult to use because of its effectiveness. On the other hand, the rotary type requires a fine structure because the rotary structure of the loupe is constructed in a small space, which also has the problem of being expensive.

The purpose of the present invention is to replace the conventional cursor magnifying glass, which is difficult to use and expensive, with a rotating type, easy to use, simple lock structure, and inexpensive.

[Means for solving problems]

In order to solve the conventional problems, the present invention includes a rotary support part that rotatably supports the magnifying glass, and an elastic support part for the magnifying glass while the magnifying glass is rotated, and the elastic force is zero in at least two rotational positions of the magnifying glass. It is constructed of a magnifying glass support having a substantially U-shaped spring portion arranged so as to be close to each other.

[Example] Hereinafter, an example of the present invention will be described based on the drawings. In FIG. 1, 1 is a cursor body to which a magnifying glass support 2 is fixed. The magnifying glass support 2 has a rotating shaft 2a, and supports the magnifying glass 3 rotatably. The magnifying glass 3 has end faces 3a and 3b as shown in FIG. 3 at positions equidistant l from the rotating shaft 2a.
Further, there is a spring portion 2b which is formed in a substantially U-shape with the upper surface located at a position approximately l away from the rotating shaft 2a.
FIG. 2 is a perspective view of the magnifying glass support 2, in which the spring portion 2b is separated from the column portion 2c and fixed to a wall 2d. This allows for free elastic deformation.

The cursor magnifying glass constructed as described above is deformed as shown in FIG. 3 and stabilized at two rotational positions. Third
Figures A and D are stable positions, where the spring portion 2b is not deformed. At B, since the magnifying glass pushes the right side of the spring part 2b from the center, the U-shaped lower part of the spring part 2b deforms and produces a large elastic force. In this case, magnifying glass 3 is arrow F
is pushed in the opposite direction. At C, since the magnifying glass pushes the left side of the spring part 2b from the center, the U-shaped upper part deformation of the spring part 2b produces a large elastic force. In this case, the magnifying glass 3 is pushed in the direction of arrow F. As a result, the cursor magnifier has two stable positions as shown in Figures A and D.

[Effect of idea]

As described above, the present invention has a two-part structure, the loupe support 2 and the loupe 3, which allows the loupe to be easily changed in position, and can be stably fixed in two positions.The structure is also simple and can be realized using large parts, so plastic molding is used. It is possible to provide an inexpensive cursor magnifying glass that can be sufficiently manufactured using techniques such as the above.
