DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display screen for a predetermined input information displayed on a CRT or a liquid crystal display screen of an automatic transaction apparatus. The present invention relates to an information input device that outputs an electric signal indicating that the input information has been selected when selected and pressed, and an unevenness forming panel used in the information input device.

[0002]

2. Description of the Related Art An information input device widely used in a conventional automatic transaction device and the like is a key set and displayed at a predetermined position on a flat screen called a so-called touch panel combined with a CRT or a liquid crystal display device. Is mainly touched or depressed with a finger or the like, and information on the corresponding position is sent to the control unit as an electric signal, so that the selected information is input-processed. Such an information input device is different from numeric keys such as a keyboard whose position is fixed, and is excellent in that arbitrary keys can be displayed in an arbitrary arrangement. Conventional technology of a touch panel in an information input device includes a resistive film type, a capacitance type, an ultrasonic type, an optical type, and the like, and a capacitance due to a finger touching the touch panel surface, a surface acoustic wave, A change in a light beam or the like, or a change in a resistance value due to pressing is read as position information on the touch panel, and this is converted into an electric signal as input information and transmitted to the control unit.

Further, by changing the screen displayed on the display unit in accordance with an instruction from the control unit, the operation keys can be of any type and arrangement. Examples of the piezoelectric input device include a device using a piezoelectric material such as a PVDF film (JP-A-56-92634, JP-A-1-121918, etc.) and a device using a ferroelectric liquid crystal ( JP-A-2-
207430, JP-B-4-29086, etc.) have been proposed. However, in the above-mentioned prior art, there is a problem that the input sensation of the input user is poor because there is no input sensation that can be felt by touching the flat plate, for example, like a keyboard. Such a problem also causes a failure by strongly pressing the surface of the touch panel due to the lack of input feeling.
In addition, since the input user performs input operations many times due to the sparseness of the input sensation, problems such as erroneous input occur.
On the other hand, low vision persons such as the elderly and visually impaired have a problem that, in the case of a flat panel, the positions of input keys cannot be clearly determined, and erroneous operations increase even if there is an auditory support device such as voice guidance. .

Further, an input device has been proposed in which a keyboard with a projection is arranged on a conventional touch panel so as to overlap with the touch panel. However, this technique reversibly changes the shape of the keyboard with a projection in accordance with display information. I couldn't do it and could only respond to limited information. At the same time, by stacking a keyboard with projections in addition to the conventional input touch panel, there are problems in that the number of components increases, the cost increases, and the device becomes complicated (Japanese Patent Laid-Open No. Hei 6-332602). Such).

[0005]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an input feeling by a tactile sensation in the same manner as a normal keyboard by using a concave and convex shape such that a key position can be confirmed by touching with a finger. An information input that can improve the input feeling of the input user and can perform an accurate input operation, and can form an uneven shape corresponding to an arbitrary display image by reversibly changing the uneven shape to a desired shape. It is to provide a device. Another object of the present invention is to provide a concavo-convex formation panel having the function of a conventional touch panel and having a concavo-convex shape that changes.

Next, a description will be given of the present invention which has solved the above-mentioned problems. In the description of the present invention, reference numerals in parentheses added after constituent elements of the present invention denote constituent elements of the present invention. Are the reference numerals of the constituent elements of the embodiment described later corresponding to. The reason why the present invention is described in correspondence with the reference numerals of the components of the embodiments described later is to facilitate understanding of the present invention, and not to limit the scope of the present invention to the embodiments.

(1st invention) In order to solve the aforementioned problem,
The unevenness forming panel of the first invention of the present application has the following requirements (A0
(A01) A base material (1) that covers one surface of the unevenness forming layer (5) and a surface protective layer (8) that covers the other surface. ), (A0
2) Irregularity-forming stimulus applying means for selectively applying an irregularity-forming stimulus to a predetermined portion of the unevenness-forming layer (5); (A03) Increasing or decreasing the volume of the stimulus-imparting portion to which the irregularity-forming stimulus is applied The unevenness forming layer (5) for forming an unevenness pattern on the surface protective layer (8).

(Explanation of the surface protective layer (8)) The surface protective layer (8) includes polyvinyl chloride, polyvinylidene chloride, modified polyvinyl alcohol-based polymer, polyethylene, polypropylene, polyvinyl butyral, urethane rubber sheet, and silicone. Various transparent sheets such as rubber sheet and latex rubber sheet can be applied, and the thickness is 1μm
It is preferably in the range of 〜100 μm. This is because when the thickness of the sheet is 1 μm or less, the strength becomes insufficient,
This is because breakage such as tearing easily occurs during use. On the other hand, if the thickness of the sheet is 100 μm or more, there is a problem that it is difficult to form unevenness due to swelling of the gel.

(Description of the base material (1)) The base material (1)
As the material, the same material as that for the surface protective layer (8) can be used, and a transparent resin material such as the acrylic resin or the polycarbonate resin can also be used. The material of the base material (1) is not particularly limited as long as it is transparent, but the thickness is preferably in the range of 1 mm to 10 mm. This means that if the thickness is 1 mm or less,
This is because the possibility of breakage increases due to a decrease in strength. On the other hand, when the thickness is 10 mm or more, it is not preferable because the weight increases and the manufacturing cost increases.

(Explanation of the concavo-convex forming layer (5)) The concavo-convex forming layer (5) is constituted by arranging a material in which the volume of the stimulating portion is increased or decreased by the stimulus for forming the concavity and convexity such as the electrical stimulation or the thermal stimulation. can do. As the material whose volume is increased or decreased by the stimulus, a polymer gel layer (5) whose volume is increased or decreased by absorbing or discharging a swelling liquid by an electric stimulus or a thermal stimulus can be used. The polymer gel layer (5) increases or decreases in volume by absorbing or discharging the swelling liquid at a portion (stimulus-providing portion) to which a stimulus for forming concavities and convexities such as voltage and heat is applied, so that the surface protection is achieved. An uneven pattern can be formed on the layer (8). As means for applying a stimulus for forming concavities and convexities to a predetermined portion of the polymer gel layer (5), a concavo-convex forming electrode (2, 7; 2, 7 ') for applying a voltage to a predetermined portion of the polymer gel, It is convenient to use an applying means, but it is also possible to use a heating means for heating a predetermined portion of the polymer gel with a heater, an energy beam or the like.

The polymer gel is not particularly limited as long as it is an electrolyte gel, but is preferably polymethacrylic acid, polyacrylic acid, acrylic acid, a copolymer of methacrylic acid and acrylamide, or poly-2-acrylamido-2-methyl. Propanesulfonic acid, polystyrenesulfonic acid, polyallylsulfonic acid, polymethacrylsulfonic acid and their alkali metals, alkaline earth metals,
Various polymer gels containing at least one crosslinked polymer of ammonium salt as a main component can be applied.

The method for producing the polymer gel is not particularly limited, and various methods described in "Basics and Applications of Gel-Soft Materials I, Ogino Kazuyoshi et al., Sangyo Tosho" can be applied. Usually, a method is used in which a small amount of a crosslinkable monomer is mixed together with the monomer constituting the polymer gel and polymerized by aqueous polymerization, emulsion polymerization, solution polymerization, or the like. Examples of the crosslinkable monomer include ethylene glycol diglycidyl ether, methylene bisacrylamide, hydroxyethyl methacrylate, glycidyl methacrylate, glutaraldehyde, divinyl ether, and the like, and the amount thereof may be small enough to maintain the strength of the gel.

The preferred polymerization method is a plasma-initiated polymerization method. This is because the plasma-initiated polymerization method increases the molecular weight of the polymer, increases the gel strength, and increases the volume change rate of the gel, so that a high piezoelectric function can be obtained. Plasma-initiated polymerization is a method in which polymerization is started in the presence of glow discharge plasma, and then post-polymerized in the absence of the plasma.The monomer and a small amount of an aqueous solution of a crosslinkable monomer are cooled with liquid nitrogen or the like and frozen. Degas under reduced pressure (about 0.1 to 0.0001 Torr). After degassing, the frozen monomer solution is gradually warmed, and when slightly melted, plasma irradiation is performed for several tens of seconds.
At this time, water and the monomer are turned into plasma by performing glow discharge at about 20 to 200 watts. Thereafter, the mixture is allowed to stand for several hours to one day to allow post-polymerization to proceed to form a gel.

The piezoelectric effect of a polymer gel due to a constant load is as follows:
It is presumed that the application of pressure causes the polymer chains inside the polymer gel to elongate, which promotes the dissociation of ionic functional groups such as carboxyl groups on the polymer chains and develops a potential. The pressing load is not particularly limited, but is usually 10 to 10
It is in the range of 00 g / cm ² . This is because although depending on the properties of the gel, a load of 10 g / cm ² or less does not provide a sufficient piezoelectric function, but a strong load of 1000 g / cm ² or more may break the gel and is not preferable. is there.

The polymer gel of the present invention preferably has a thickness in the range of 1 mm to 10 mm. This is because if the thickness is 1 mm or less, it is difficult to form sufficient unevenness. On the other hand, when the thickness is 10 mm or more, it is not preferable because performance problems such as a time-consuming change in volume of the polymer gel occur. The piezoelectricity of the polymer gel is known, and K. Sawahata et al.
Macromol. Papid Commune, 16, 713 (1995) and the like.

(Explanation of the means for supplying the lubricating liquid) The unevenness forming layer (5) whose volume is increased or decreased by the unevenness forming stimulus.
Is formed by the polymer gel layer (5), the polymer gel layer (5) absorbs or discharges the swelling liquid when increasing or decreasing the volume. The swelling liquid can be accommodated inside the concavo-convex formed panel, or can be supplied to the concavo-convex formed panel from outside when necessary. When the swelling liquid is accommodated in the unevenness forming panel, it is preferable to provide a swelling liquid holding layer (3) disposed inside the unevenness forming panel. In this case, the swelling liquid holding layer (3) is composed of a porous, multi-layered fibrous or slender liquid swelling liquid holding member and a swelling liquid so that the swelling liquid can be easily absorbed when the gel swells. Is done. And these swelling liquid holding layers (3)
For example, polyethylene, polypropylene, or the like, so that the display content of the lower layer can be recognized from the surface of the unevenness forming panel (P).
It is preferable to apply a material having transparency to a visible image, such as polyvinyl chloride, an acrylic resin, a polystyrene resin, and polycarbonate.

The swelling liquid holding layer (3) preferably has a thickness of 1 mm to 5 mm. This is because if it is less than 1 mm, it is not possible to hold a sufficient swelling liquid for the polymer gel to swell, while if it is 5 mm or more, the entire unevenness forming panel (P) by holding the swelling liquid more than necessary. This is because there is a problem that the weight of the swelling liquid holding member increases and the cost of the swelling liquid holding member increases. Further, the swelling liquid used in the present invention is an aqueous solution of an electrolyte forming monovalent ions such as sodium chloride, potassium chloride, ammonium chloride, sodium acetate, hydrochloric acid, sodium hydroxide, dodecylpyridine, or acetone, ethanol, methanol It is a liquid containing at least one kind as a main component among a mixture of an organic solvent compatible with water, such as water, and the electrolyte solution. When an aqueous solution of an electrolyte is used as the swelling liquid, the electrolyte concentration is preferably in the range of 0 to 0.1 mol / l. This means that the electrolyte concentration is 0.1 mol / l
This is because there is a problem that sufficient volume change of the polymer gel due to electrical stimulation does not occur.

On the other hand, when a mixture of an organic solvent and an electrolyte solution is used as the swelling liquid, the amount of the organic solvent is preferably 4 parts by weight or less per 1 part by weight of the electrolyte solution. This is because, in a mixed solution containing an organic solvent at least four times the weight of the electrolyte solution, there is a problem that a sufficient change in volume of the polymer gel due to electrical stimulation does not occur. The volume change behavior of the polymer gel is known, and J. Ricka et al., Swelling of lonic Gels: Quantitative Performance

(Stimulus providing means (2, 7; 2, 7 ')
Description: When a polymer gel having a piezoelectric effect is used for the polymer gel layer (5) and the stimulus for forming concavities and convexities is applied by a voltage, a voltage is applied to a predetermined portion of the polymer gel layer (5). The unevenness forming electrodes (2, 7; 2, 7 ') to be applied are used. Further, the polymer gel having the piezoelectric effect generates a potential or a current when a predetermined load is applied. In this case, an electric signal indicating that the input information is selected is detected based on a potential or a current generated by the polymer gel when a predetermined load is applied to a portion corresponding to the display portion of the input information. By providing the selected information detection electrodes (4, 7), the selected input information can be detected. The selection information detection electrodes (4,
7) can be formed on the surface of the swelling liquid holding layer (3) in contact with the polymer gel layer (5). Therefore, in the present invention, the selection information detection electrodes (4, 4) for detecting an electric signal indicating a position where the load of the polymer gel is applied.
7) can be used. Therefore,
The concavo-convex forming electrodes (2, 7; 2, 7 ') and the selection information detecting electrodes (4, 7) for applying a concavo-convex forming stimulus to a predetermined portion of the polymer gel by voltage will be described.

The concavo-convex forming electrodes (2, 7; 2, 7 ') of the polymer gel may have any configuration as long as they can form concavities and convexities in accordance with displayed input information, and are displayed on the display surface. An uneven pattern corresponding to the shape of input information is formed by a dot matrix type electrode formed by combining a plurality of dot-shaped concave or convex portions, or has a shape corresponding to the shape of input information displayed on the display surface. It can be formed by electrodes. The dot matrix type electrode is constituted by a plurality of strip electrodes parallel to the X-axis direction and a plurality of strip electrodes parallel to the Y-axis direction perpendicular to the X-axis direction and arranged opposite to the plurality of strip electrodes. Or an active matrix type electrode in which one is a flat electrode and the other is a TFT electrode.

In the concavo-convex forming panel (P) having the concavo-convex forming electrodes (2, 7) and the selection information detecting electrodes (4, 7) for detecting the selection information detecting signal by the piezoelectric effect, the concavo-convex forming electrodes (4, 7) are provided. 2, 7) is the substrate (1)
A plurality of parallel X-axis direction electrodes (2) for forming concavities and convexities formed on the inner surface of the substrate and a direction perpendicular to the X-axis direction electrode (2) for forming concavities and convexities formed on the inner surface of the surface protective layer (8). A plurality of extending and extending Y-axis direction electrodes for forming and detecting parallel unevenness (7)
Can be constituted by At this time, the selection information detection electrodes (4, 7) are connected to a plurality of parallel detection X-axis direction electrodes (4) formed on the surface of the swelling liquid holding layer (3) in contact with the polymer gel layer (5). Can be constituted by In that case, a ground electrode (6) parallel to the surface of the swelling liquid holding layer (3) can be arranged inside the polymer gel layer (5). This configuration includes a Y-axis direction electrode for forming concavities and convexities for applying an electrical stimulus for causing a change in the concavo-convex shape of the polymer gel, and a Y-axis electrode for detecting electric potential or current generated by the piezoelectric function of the polymer gel. Although this is an example in which the direction electrode is also used, separate electrode groups may be provided.

The irregularity forming electrodes (2, 7), the irregularity forming and detecting Y-axis direction electrode (7) and the irregularity forming X-axis direction electrode (2) are made of ITO (indium tin oxide), tin oxide or the like. Metal oxides, or polypyrrole, polythiophene, polyacene, polyacetylene, polyaniline,
Conductive polymers such as polyphenylene, or PET
(Polyethylene terephthalate), polyvinyl chloride, polyethylene, polyvinylidene chloride, and other transparent polymer films in which metal fine particles, metal oxide fine particles, conductive polymer fine particles, and the like are dispersed. . At this time, the thickness of the electrode is 1 μm to
It is preferably in the range of 100 μm. This is because if the thickness of the electrode is 1 μm or less, the strength becomes insufficient, and breakage such as cracks easily occurs during use. on the other hand,
If the thickness of the electrode is 100 μm or more, there is a problem that it is difficult to form irregularities due to swelling of the gel.

The irregularity change according to the display information of the polymer gel is caused by applying an electrical stimulus according to the display information from above and below the polymer gel. Application of a desired electrical stimulus can be performed by applying a voltage between the Y-axis direction electrode (7) for forming and detecting the unevenness which sandwiches the polymer gel and the X-axis direction electrode (2) for forming the unevenness. . The irregularity forming and detecting Y-axis direction electrode (7) is held in close contact with the surface protective layer (8) and is arranged in contact with the polymer gel, and the irregularity forming X-axis direction electrode (2) is a base material. It is held in close contact with (1) and can be placed away from the polymer gel via the swelling liquid holding layer (3).

Further, the electrodes (2, 7;
2, 7 ') are arranged as close as possible so that the thin plate-shaped electrodes do not come into contact with each other as shown in FIG. 2, and the X-axis direction electrode (2) for forming unevenness is used for forming and detecting unevenness. Y
It is arranged to intersect with the axial electrode (7).
The polymer gel undergoes a volume change at the intersection of the unevenness forming electrodes (2, 7) in the Y-axis direction and the X-axis direction to form a desired unevenness shape. At this time, the width of the two concavo-convex forming electrodes (2, 7) should be set according to the information to be displayed, and is at least larger than the size of a key (for example, 1 cm square) that a user can touch or press with a finger. It is preferable that the setting can be made small so that an arbitrary key arrangement display can be supported.
On the other hand, a resolution of about 1 / mm is sufficient to display keys in an arbitrary arrangement, and forming finer electrodes than this is not desirable from the viewpoint of driving and manufacturing. Therefore, it is preferable that the width of the electrode is in the range of 1 mm to 1 cm and the electrode interval is 0.05 mm to 0.5 mm.

Next, a ground electrode (6) used for detecting a potential or current generated by the piezoelectric function of the polymer gel, a Y-axis direction electrode (7) for forming and detecting unevenness and an X-axis direction electrode (4) for detection. ), The Y-axis direction electrode for unevenness formation and detection (7) is as described above. On the other hand, the ground electrode (6) is provided with Y
It is arranged as a common electrode over the entire gel substantially parallel to the plane formed by the axial electrodes (7). The ground electrode (6) has a mesh structure with a gap so as not to inhibit the swelling of the polymer gel. The mesh of the ground electrode (6) preferably ranges from 1 mm to 1 cm. This is because if the mesh spacing is less than 1 mm, the display of the lower layer becomes unrecognizable. On the other hand, if the mesh spacing is more than 1 cm, the upper and lower electrodes (2, 7; 2, 7 ') for forming the unevenness are formed. This is because a sufficient grounding effect cannot be expected to exceed the width.

The ground electrode (6) has a diameter of 0.0.
The conductive material is preferably in the range of 1 mm to 0.2 mm. The problem is that if the diameter is 0.01 mm, the strength is insufficient and there is a high possibility that the panel will be broken by pressing the unevenness forming panel (P). On the other hand, if the diameter is 0.2 mm or more, the lower layer display can be recognized. This is because a problem of disappearing occurs. As the conductive material used for the ground electrode (6), various metals such as gold and platinum, and various conductive nonmetal materials such as carbon fiber can be used. The ground electrode (6) is preferably inserted in advance before performing a crosslinking reaction when producing a polymer gel, but may be sandwiched between two polymer gels.

The X-axis direction electrode for detection (4) has a width of 1 mm to 1 cm, similarly to the X-axis direction electrode for unevenness (2).
The thin plate-shaped electrode of 0.05 mm to 0.5 mm
Are arranged in close contact with the polymer gel between the polymer gel and the swelling liquid holding layer (3) so as to intersect with the Y-axis direction electrode for unevenness formation and detection (7). ing. However, the X-axis direction electrode for detection (4) is different from the X-axis direction electrode for unevenness (2) so that the polymer gel does not hinder the absorption of the swelling liquid inside the swelling liquid holding layer (3). A divided plate-like electrode having a mesh structure similar to that of the ground electrode (6) is used. The mesh size, electrode material and diameter of the detection X-axis direction electrode (4) are the same as those of the ground electrode (6).

(Operation of the First Invention) The unevenness-formed panel (P) according to the first invention of the present application having the above-described structure is a substrate (1) that covers one surface of the polymer gel layer (5). And a surface protective layer (8) covering the surface on the other side. The unevenness forming stimulus applying means (2, 7; 2, 7 ') selectively applies unevenness forming stimulus to a predetermined portion of the polymer gel layer (5). The polymer gel layer (5) increases or decreases in volume when the stimulus-imparted portion to which the stimulus for forming concavity and convexity is applied absorbs or discharges the swelling liquid, so that the surface protective layer (8) has a concavo-convex pattern. To form

The concavo-convex forming panel (P) is transparent and used in a state of being superimposed on the display surface of the display device (D), and a portion corresponding to a display portion of input information on the display surface is projected or recessed. You can do it. In that case, the unevenness forming panel (P) can visually recognize the input information on the display surface through the unevenness forming panel (P).
As the display device (D), various existing display devices such as a CRT and a liquid crystal display device can be used. Then, as the stimulus applying means (2,7; 2,7 '), a concavo-convex forming electrode (2,7; 2,7') for applying a voltage to a predetermined portion of the polymer gel, that is, a voltage applying means was used. In this case, the concavo-convex forming electrodes (2, 7; 2, 7 ') are configured so that the shape of the voltage application portion of the polymer gel layer (5) corresponds to the outer shape of the input information on the display surface. Thereby, the surface of the concavo-convex formation panel (P) can be protruded for each of the plurality of input information display portions displayed on the display surface.
In this case, the operator can clearly confirm the input area (the part pressed to select the input information).

The unevenness forming panel (P) can be used in a state of being superimposed on the display surface of the display device (D).
Then, the concavo-convex forming electrodes (2, 7; 2, 7 ') are configured so that the shape of the voltage application portion of the polymer gel layer (5) corresponds to the outer shape of the input information on the display surface. The surface of the concavo-convex forming panel (P) can be made convex for each of a plurality of input information display portions displayed on the display surface. When the concavo-convex forming electrodes (2, 7; 2, 7 ') are formed by a plurality of concavo-convex forming X-axis direction electrodes (2) and concavo-convex forming and detecting Y-axis electrodes (7), a set of dots is formed. Thereby, uneven patterns of various shapes can be formed. The polymer gel of the polymer gel layer (5) in the area that has been electrically stimulated by the application of the voltage changes in volume and protrudes from the surrounding unchanged area. By forming such a concavo-convex pattern, the position of the input key can be easily and tactilely sensed when inputting necessary information.

In the unevenness forming panel (P) according to the first invention, the polymer gel which generates a potential or a current when a predetermined load is applied is used, and a predetermined portion is provided at a portion corresponding to the display portion of the input information. When a selection information detection electrode (4, 7) for detecting an electric signal indicating that the input information has been selected is provided based on a potential or a current generated by the polymer when a load is applied. When a predetermined portion of the concavo-convex pattern formed corresponding to the image displayed on the display device (D) is pressed down with a predetermined load, a potential or a current is generated by the piezoelectricity of the polymer gel, and the display is performed on the display surface. It is possible to detect the input information selected by pressing the input information among the input information.

Similarly, when the unevenness forming panel (P) of the first invention is arranged on the touch panel (T) arranged on the display surface of the display device (D), the same applies to the display device (D). By pressing a predetermined portion of the concavo-convex pattern formed corresponding to the image to be displayed with a predetermined load, a potential or a current is generated and selected by the pressing of the input information displayed on the display surface. Input information can be detected. Therefore, by using the unevenness forming panel (P) of the first invention, it becomes possible to display the next image on the display device (D) based on the selected input information.

The electrode for forming unevenness (2, 7; 2, 7 ')
Are formed by a plurality of X-axis direction electrodes for unevenness formation (2) and Y-axis electrodes (7) for unevenness formation and detection, and the selection information detection electrodes (4, 7) are X-axis direction electrodes for detection (4). In the case where the unevenness forming and detecting Y-axis direction electrode (7) is used, when an area of the unevenness forming panel (P) where desired input information (input key) is pressed, the unevenness forming panel (P) is pressed. An electric signal (change in potential) corresponding to the position information (selected input information) input in P) is generated, and the X-axis direction electrode for detection (4) and the Y-axis direction electrode for unevenness formation and detection (7) are formed. ) Can be output to an external signal processing unit. The signal processing unit can display the next new input information based on the selected input information, or can perform a predetermined process. Next, when new information is displayed, the uneven shape changes again according to the displayed information, and a key (projection) arranged according to the input information different from the previous time is formed, and the input is awaited. It can be.

As described above, the unevenness of the desired layout is reversibly formed in accordance with the display content of the display device (D) in which the surface of the unevenness forming panel (P) is lower, so that the input operation in the information input device can be performed. In this case, there is a clear key input interval, and an input feeling close to that of a keyboard operation can be obtained. In addition, when a visually impaired person such as an elderly person or a visually impaired person performs an input operation, the input portion can be confirmed by touching the input portion with a finger, thereby making the input operation easy and reliable. In addition, since the concavo-convex shape corresponding to the display information can be formed reversibly, the concavo-convex forming panel (P) appropriately corresponding to various information can be formed. In addition, the input / output information can be output by the concavo-convex forming panel (P), and the conventional touch panel (T) becomes unnecessary, and the apparatus can be simplified.

(Second Invention) The information input device according to the second invention of the present application has the following requirements (A019) to (A021). (A019) A display for displaying input information. An information selection signal that indicates that the input information has been selected is output when the input information is visible and is touched on a portion corresponding to the display portion of the input information, while being arranged on the display surface of the device (D).

(A020) A concavo-convex formation panel (P) having a concavo-convex formation layer in which a concavo-convex pattern is formed on the surface by increasing or decreasing the volume of a portion to which the concavo-convex stimulus is applied while being arranged on the touch panel (T). (A021) The unevenness for selectively applying a stimulus for forming unevenness to a predetermined portion of the unevenness forming panel (P) so as to form an unevenness pattern according to the input information displayed on the display device (D). Forming stimulus applying means (2, 7 ').

(Operation of the Second Invention) In the information input device of the second invention of the present application having the above-mentioned configuration, the input information is disposed so as to overlap the display surface of the display device (D) for displaying the input information, and the input information is displayed. The visible touch panel (T) outputs an information selection signal indicating that the input information has been selected by touching a portion corresponding to the display portion of the input information. The concavo-convex forming panel (P) arranged so as to overlap the touch panel (T) has a concavo-convex forming layer in which the concavo-convex pattern is formed on the surface by increasing or decreasing the volume of the portion provided with the concavo-convex stimulus. The unevenness forming stimulus applying means (2, 7 ') selectively applies unevenness forming stimulus to a predetermined portion of the unevenness forming panel (P). Therefore, an uneven pattern corresponding to the input information displayed on the display device (D) is formed on the uneven formation panel (P). Therefore,
Display device (D) by output signal of touch panel (T)
Can be detected as the input information selected from among the input information displayed in. The next input information can be displayed according to the detected input information.
