Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method of manufacturing a tablet input board for a word processor (hereinafter referred to as a word processor) used when inputting characters, figures, etc. into a word processor.

2. Description of the Related Art In recent years, tablet input boards have been increasingly used to input characters, figures, etc. as coordinate data into processing devices such as computers.

The tablet input board can be used to input original images such as characters and figures by hand.

Alternatively, it is possible to use a keyless flat-board word processor that can create sentences by inputting characters, numbers, figures, etc. by specifying a desired position through computer processing of coordinate positions.

Various methods for obtaining coordinate data on a human-powered board for tablet input boards have been announced and implemented. A plurality of conductors are arranged under the surface of the input board perpendicular to the X-axis direction and the Y-axis direction, and a magnetic field detection means is provided to detect the magnetic field obtained when a current is supplied to the conductors from the outside. There is a tablet input device that uses a detector to detect the magnetic field, determines the distance from the plurality of conductors to the detector based on the intensity of the detected magnetic field, and reads it as coordinate values. Further, a plurality of conductors are arranged under the surface of the input board to be perpendicular to the X-axis direction and the Y-axis direction, and a magnetic field generating means such as an excitation coil is brought close to the input board to generate a magnetic field from the plurality of conductors. There is a tablet input device that allows you to know the distance to a device and read it as coordinate values. These so-called electromagnetic induction type tablet input devices can be provided with a substantial function by, for example, forming a thin conductor on the input board, and the above-mentioned usage pattern can be realized.

Hereinafter, an example of the input board of these tablet human-powered devices will be described with reference to the drawings.

FIG. 4 is a perspective view of a configuration example of a conventional tablet input board, in which 1 is a conductive wire arranged in the X-axis direction, 2 is a conductive wire arranged in the Y-axis direction, and 3 is made of resin, etc. The insulating member 4 is composed of color figures printed on the surface thereof.

Note that the conductive wire 1 is located below the conductive wire 2, and is an input board disposed so as not to be electrically conductive to each other.

Problems to be Solved by the Invention However, when considering an electromagnetic induction type tablet input board with the above structure, it is desirable that the distance between the detection part and the detected part be as close as possible. In order to arrange wire 1 and conductive wire 2 on input board 3, these conductive wires 1 and 2 must be encapsulated at the same time when molding resin, etc., which is extremely difficult in terms of construction method and is also costly. I had a problem with sticking.

In view of the above-mentioned problems, the present invention is a tablet input board for Warb L+, which enables precise and reliable construction of matrix-like conductors and colored figures for generating or detecting magnetic fields. It provides:

Means for Solving the Problems In order to solve the above-mentioned problems, the tablet input board of the present invention has a plurality of parallel first boards formed by a printing method using conductive paste on one side of an insulating plastic substrate. a linear conductor, and a plurality of parallel second linear conductors perpendicular to the first linear conductor formed by a printing method using a conductive paste on the other surface of the insulating plastic substrate. After forming a colored figure using a transfer method on the upper surface of the insulating plastic substrate having a body, a translucent insulating plastic sheet is coated with a translucent tack adhesive. It is coated and then a reinforcing plate is attached.

Function The present invention is a precision word processor used in Japanese language word processors that can also have functions such as handwritten character recognition, in which figures with sufficient insulation and coloring are accurately formed in the necessary parts by the above-described structure. This makes it possible to easily implement a tablet input board.

EXAMPLE Hereinafter, a method for manufacturing a tablet input board according to an example of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of the present invention, in which 7 is an insulated plastic substrate, 5 is the above-mentioned insulated plastic substrate 7, and a plurality of lines are formed on the lower surface of the insulated plastic substrate 7 by a printing method using a conductive paste in parallel to the X-axis direction. A plurality of linear conductors 6 are formed on the upper surface of the insulating plastic substrate 7 by a printing method using a conductive paste in parallel to the Y-axis direction, and each of the linear conductors 5.6 is 8, which is formed in a matrix shape, is a colored figure formed by a transfer method on the upper surface of the insulating plastic substrate having the linear conductors 5.6. 9 is a translucent tank adhesive formed on the upper and lower surfaces of the substrate, on which the colored figure 8 was formed by a transfer method on the upper surface of the insulated plastic substrate having each of the linear conductors 5 and 6. It is a drug. 10 is a translucent plastic sheet formed on the upper and lower surfaces of the tank adhesive having translucency of 9. 11 is a tack adhesive formed to attach the reinforcing plate 12 to the lower surface of the above structure. 12 is a reinforcing plate as already mentioned. 2 is a sectional view of this embodiment, and FIG. 3 is a sectional view taken along line AA' in FIG.

A method for manufacturing the tablet input board configured as described above will be described below with reference to FIGS. 1, 2, and 3.

A plurality of parallel lines are printed on one surface of the insulating plastic substrate 7 by using a conductive paste in which conductive fine powder is dispersed in a resin, for example, by offset printing, gravure printing, or screen printing. Conductor 5
form. Then, on the other surface, a plurality of parallel linear conductors 6 orthogonal to the above-mentioned 5 are formed by the same method to obtain a matrix-like conductor 5.6. Next, a colored figure 8 is applied to the upper surface of the insulating plastic substrate 7 including the linear conductor 5.6 using, for example, a thermal transfer method, an adhesive transfer method, or the like.
After forming by a pressure sensitive transfer method, a sublimation transfer method, etc., a translucent tank adhesive 9 is applied to an insulating plastic sheet 10 which also has translucent properties by a roll coater method, a spray method, a transfer method, etc. The conductor 5.6 and the colored pattern 8 are coated on the upper and lower surfaces of the insulating plastic substrate 7 by a vacuum press method, a laminator roll method, or the like.

The tack adhesive 9 having translucency is directly formed on the insulating plastic substrate 7 containing the above-mentioned 5.6 and the cherry-colored figure 8 by, for example, a screen printing method or a transfer method, and then it becomes translucent. A method of covering with an insulating plastic sheet 10 is also possible. Next, apply tack adhesive No. 11 to No. 12 reinforcing plate using screen printing method or transfer method.
After forming by a coating method or the like, it may be attached to the lower surface of the above structure. It should be noted that the tack adhesive having a translucency of 9 and the translucency of 10 are limited to those formed on the lower surface of the insulating plastic substrate containing the conductor 5.6 and the colored figure 8. The insulating plastic sheet does not necessarily have to be translucent; it is basically possible to use a non-transparent one. However, due to manufacturing issues, the method of the present invention was adopted because a translucent material is superior in accuracy or precision.

Note that polyester, polycarbonate, polysulfone, polyethylene, vinyl chloride, acrylic, and the like are suitable for the insulating plastic film substrate 7. Even if the thickness of the insulating plastic substrate 7 is about 10 μm, the insulation property is sufficient. Further, as the conductive paste used to form the linear conductors 5.6 in a matrix shape, there are various types of conductive pastes such as gold paste, silver paste, nickel paste, copper paste, carbon paste, etc., such as screen printing, gravure printing, or offset printing. A commercially available conductive paste ink for printing is sufficient for practical use.

Thermal transfer method, adhesive transfer method, pressure-sensitive transfer method, etc. are suitable for the colored figures formed by the transfer method. As the translucent tack adhesive of Nos. 9 and 11, adhesive types such as polyurethane, polyethylene, polyester, and acrylic, ultraviolet irradiation types, semi-cured types, and the like are suitable. In addition, a plate material with an electrical insulation value of IOMΩ or more is suitable as the reinforcing plate, and if a frame plate or the like is installed at the outer end, it is even more effective in terms of strength and data input.

Effects of the Invention As is clear from the above explanation, the word processor tablet input board of the present invention has a simple structure, high precision, strength and durability, easy construction, and sufficient electrical insulation. , can be formed by enclosing precisely colored figures in the necessary parts, and is especially useful as a tablet input board for word processors with handwriting recognition function.
It brings about a great effect when inputting other characters and figures.
