Description

[Detailed description of the invention] The present invention is a magnetophoretic display method in which a magnetic field is applied to a plastic fluid fluid in which magnetic particles are dispersed to cause the magnetic particles to migrate, thereby changing the color of the plastic fluid fluid to display a display. .

This invention relates to a stamp on which a magnetic field is applied in a display panel (hereinafter referred to as a plastic flow display panel) according to Japanese Patent Application Laid-Open No. 51-58893.

Conventionally, the method of applying a magnetic field to the plastic flow display panel was as follows:
This was done using a writing instrument with a magnet attached to one end of the shaft.

Therefore, it takes a lot of effort to display pictures, patterns, etc., and is difficult for young children.

The present invention was devised for the purpose of eliminating the above-mentioned drawbacks, and will be described in detail below with reference to the drawings. As shown in FIG.
to fix.

The shape of the support tube 2 is not limited to a cross shape, but may be a T-shaped shape or a vertical or horizontal letter shape.

Next, an insertion handle 4 is erected on one side edge of the transparent plate 3, and a magnet 5 shaped in a symmetrical or figurative shape such as letters, numbers, or codes is attached to the back side of the transparent plate 3. , constitutes stamp 6.

The insertion handle 4 of the stamp 6 can be inserted into and removed from any part of the support tube 2.

To use this, the desired stamp 6.6 to be displayed on the plastic flow display board is inserted into each node of the support tube 2, and the stamp 6 to be displayed is placed on the board. When the desired shape is formed by the magnet 5, a magnetic field is applied to the magnetic particles inside the disc, and the shape of the magnet 5 is displayed by changing color.

For example, if the stamp is in the shape of a flower as shown in Figure 1,
By touching these in succession on the board, a continuous display of flowers can be easily made.

To erase the display, magnetic particles are attracted to the bottom surface of the plastic flow display board using another magnet (not shown) provided on the bottom surface of the board.

Therefore, if the magnet 5 of the stamp 6 is prepared with letters, numbers, codes, etc. differentiated according to the purpose, the purpose can be easily displayed. If the shape 9 is used, a doll with rich dynamic deformation as shown in FIG. 3 can be obtained.

In addition, since the forming part of the magnet 5 of the stamp 6 is transparent, the position can be determined visually when displaying, and two to four stamps 6 can be inserted into the support tube 2, so the necessary stamp 6 can be inserted each time. By rotating the handle 1, the handle 1 can be brought into contact with the board without the hassle of selecting and taking it out from the storage location.

As mentioned above, various characters, patterns, etc. can be displayed simply by selecting the desired stamp 6, inserting it into the support tube 2, and touching it on the board, so it is extremely interesting and even suitable for young children. It is possible to provide an effective display tool that allows complicated drawings to be easily made.

Furthermore, if a magnet 7 is provided at the other end of the handle 1, it is convenient to provide an auxiliary magnetic field to a portion that is insufficient to be indicated by the stamp 6.
