Description

[Detailed description of the invention] (Field of industrial application) The invention provides a plurality of transparent conductors on the display screen of a display device such as a CRT, and transmits the data displayed on the display screen of the display device using a transparent conductor. The present invention relates to a tactile input device that allows input by touching a conductor with a finger.

(Prior Art) Conventionally, this type of device is disclosed in Japanese Patent Application Laid-Open No. 57-45632. A plurality of transparent conductor films are formed on the display screen of the display device, and a conductor part of the tactile response that can be selected by the user's tactile finger and a conductor part of the tactile response that is connected to the conductor part of the tactile response that can be selected by the user's tactile finger, and an identification section that identifies the position of the tactile finger, and input can be made by touching the conductor section of the specified tactile response according to instructions on the display screen. For example, "Oki Research and Development" No. 121 VoL.50 No. 3 (December 1982)
With the automatic transfer device described in , if you specify the initial letter of the financial institution name, head office, branch, etc. to which you wish to transfer money using the kana keyboard, the corresponding financial institution name, head office/branch name, etc. will be displayed on the display screen of the display device. Therefore, it is possible to input the name of the desired financial institution or head office/branch by touching and selecting the circled part of the name.

FIG. 5 is a diagram showing a method of mounting the tactile input device on a display device. In the figure, 1 indicates a display device such as a CRT, and 2 indicates a tactile input device mounted on the display screen of the display device 1.

FIG. 6 is a diagram showing a conventional tactile input device. In the figure, numeral 3 indicates a conductor portion of a transparent conductor film that responds to the touch. The user selects and touches the plurality of conductor parts 3 according to the characters or figures displayed on the display screen of the display device 1 to input the information. 4, 5, and 6 are wiring boards for connecting the conductor portion 3 to an identification portion (not shown).

Next, the operation will be explained. The user selects and touches the touch-responsive conductor section 3 according to the display on the display screen of the display device 2. The identification unit identifies the touched position via the substrates 4, 5, and 6.

(Problems to be Solved by the Invention) However, the prior art device has the following problems.

The user's tactile fingers leave fingerprints on the display screen, making it difficult to see the display, so there is a problem in that cleaning tends to cause scratches, and the tactile response conductor part 3 loses its conductivity due to the scratches. . Furthermore, in order to eliminate this problem, applying a transparent, non-conductive protective film to the entire surface of the device makes it less likely to be scratched, but it has the disadvantage that it becomes inoperable.

The present invention provides a tactile input device that solves the problems of the prior art.

(Means for solving the problem) In order to solve the above problem, the present invention has a plurality of conductor parts formed on the display screen of the display device,
In a tactile input device for identifying a position on a display screen selected by a user by touching the conductor part of a material, a reinforcing protective film is provided on the surface of the conductor part, and the protective film is Each of the conductor parts is characterized in that it has an opening having a size that allows at least a finger to penetrate the protective film and come into contact with the conductor part.

(Function) According to the present invention, since the tactile input device is configured as described above, the technical means functions as follows. The protective film coated on the surface of the conductor works to protect the conductor under the protective film even if scratches occur, and the conductor can be checked by the user on the display screen of the display device. By touching the exposed portion, conduction is established through at least the conductor portion under the protective film. Therefore, since the touched conductor portion can be identified, the problems of the prior art can be solved.

(Embodiment) FIG. 1 is a diagram showing an embodiment of a tactile input device according to the present invention. In this figure, the same reference numerals as in FIG. 6 indicate the same components. Reference numeral 7 denotes a dielectric transparent protective film (shaded area) coated all around the tactile response conductor part 3.

2 and 3 are a sectional view and an enlarged plan view of the tactile response conductor portion 3 of this tactile input device. As shown in FIG. 2, the dielectric protective film 7 does not completely cover the touch-responsive conductor portion 3, but partially exposes it. Therefore, when inputting the touch finger, the third
As shown in Figure a, input can be made by touching the exposed portion 3a of the conductor portion 3. As shown in FIG. 3c, if a protective film 7 is not coated on the surface of the conductor section 3, if a scratch 8 occurs due to cleaning etc., the conductor of the conductor section 3 will be cut and input operations will no longer be possible. . However, in this embodiment, FIG.
As shown in FIG. 2, since the protective film 7 is provided, the conductor portion 3 is protected by the upper side 7a and lower side 7b of the protective film 7 even if a scratch 8 occurs. Therefore, the tactile response conductor portion 3 is not cut. As a result, conduction is established through the conductor portion 3 under the protective film 7, so that input is possible.

Therefore, the tactile input device according to this embodiment operates as follows. The user selects and touches the exposed portion 3a of the conductor portion 3 that responds to touch in accordance with the characters or graphics displayed on the display screen of the display device 2.
The identification unit identifies the touched position via the substrates 4, 5, and 6.

In the embodiments described above, the protective film 7 is coated all around the tactile-responsive conductor part 3, but the protective film 7 may be coated only on a part of the periphery, for example, the upper part 7a or the lower part 7b. Furthermore, it is clear that a similar effect can be obtained by applying a mesh-like protective film 9 as shown in FIG.

(Effects of the invention) As explained above, according to the invention, since a protective film is selectively applied to the surface of the conductor part, the strength is increased, and it is possible to operate even if there are some scratches, and the entire device Reliability can be improved.
