Abstract

PURPOSE:To surely instruct and input the part of a tablet input part corresponding to information displayed on a display surface by allowing the information displayed on the display surface of a CRT display part to reach the tablet input part while being led with an optical fiber constituting an optical fiber layer. CONSTITUTION:The information 7 displayed on the display surface 4 reaches the sensitive area 7a of the tablet input part 2 while being led with the corresponding optical fiber 11 of the optical fiber layer 10. Thus, regardless of the position of an operator who confirms the information 7, the operator can confirm the information 7 on the sensitive area 7a, and he never instructs and inputs the different position of the tablet input part 2. Then, since even the information displayed in the vicinity of the edge part of the display surface 4 where distance to the tablet input part 2 becomes large can be surely instructed and inputted, an input item can be increased remarkably.

Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention (Industrial Application Field) The present invention relates to an input/output device for checking information displayed on the display surface of a CRT display section and inputting instructions through a transparent tablet input section. .

(Prior art) This type of input/output device is shown in Fig. 4. In the figure, 1 is a device housing, 2 is a tablet input section, and 3 is a CRT display section. The CRT display section 3 shows input information. The tablet input section 2 is formed of a transparent flat plate and is arranged with the back surface 5 facing the display surface 4.The operator then displays the information on the display surface 4. Check the displayed information from the front surface 8 side of the tablet input section 2, and select the tablet input section 2 corresponding to the corresponding information 7 among the information displayed on the display surface 4.
The configuration is such that an instruction is input to the sensitive area 7a. Note that the tablet input unit 2 includes a pressure-sensitive tablet, a capacitive coupling tablet, an optical coupling tablet, and the like.

In this conventional input/output device, the display surface 4 of the CRT display section 3
Because it is curved, even if the CRT display section 3 is placed with the center of the display surface 4 as close to the tablet input section 2 as possible, the distance between the display surface 4 and the tablet input section 2 will be the same as the display surface 4. becomes larger as the distance from the center increases. Since the display surface 4 and the tablet input section 2 are separated, parallax occurs between when the information 7 is confirmed from the vertical direction A and when the information 7 is confirmed from the diagonal direction B with respect to the tablet input section 2. . Therefore, when an attempt is made to input the sensitive area corresponding to the information 7 from the diagonal direction B, the sensitive area 7b that is different from the original sensitive area 7a may be inputted, resulting in a problem of erroneous input or invalid input.

Furthermore, the operator has to take into account the parallax caused by the confirmation position when inputting instructions to the tablet input unit 2, which makes the input operation complicated and creates a sense of discomfort.

(Problems to be Solved by the Invention) As mentioned above, in conventional input/output devices, if the position of the operator's eyes when checking the information displayed on the display screen differs, the position of the information visible on the tablet input section differs. There were cases where incorrect input occurred.

In addition, the operator must take into account the positional deviation when inputting instructions for the information displayed on the tablet input section.
The operation was complicated and caused a feeling of discomfort.

The present invention has been made in view of these conventional drawbacks, and even if the position of the operator who confirms the information displayed on the display screen changes, the position of the information visible on the tablet input section does not change. Therefore, it is an object of the present invention to provide an input/output device that is less likely to cause erroneous inputs or invalid inputs, and that allows easy input operations.

[Configuration of the Invention (Means for Solving the Problems)] The input/output device of the present invention is a CRT that displays information on a display screen.
a display section, a tablet input section formed of a transparent flat plate, the back side of which is opposed to the display surface, and which detects a position corresponding to the information specified from the front side; one end of which is brought into contact with the display surface. The optical fiber layer includes a plurality of optical fibers densely formed, the other end of which is brought into contact with the back surface.

(Function) In the present invention, an optical fiber layer is provided between the display surface of the CRT display section and the back surface of the tablet input section.Therefore, the information displayed on the display surface is transmitted to each optical fiber layer. The information is guided by an optical fiber to a portion of the tablet input unit that corresponds to the portion of the display surface where the information is displayed.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to FIGS. 1 to 3.

FIG. 1 is a partially cutaway side view of the input/output device, and FIG. 2 is a perspective view of the main part.

In the figure, 1 is the device housing, 2 is the tablet input section, and 3 is the CR
In the T display section, 10 is an optical fiber layer.

Similar to the conventional example, the CRT display section 3 displays input information on the display surface 4. Further, the tablet input section 2 is formed of a transparent flat plate, and is arranged with the back surface 5 facing the display surface 4. Then, the operator checks the information displayed on the display surface 4 from the surface 8 side of the tablet input section 2,
The user is instructed to enter a sensitive area 7a of the tablet input section 2 corresponding to the relevant information 7 out of the information displayed on the display surface 4.

The optical fiber layer 10 includes an optical fiber 1 as shown in FIG.
It is shaped like a large number of 1's clustered together. The pitch between these optical fibers 11 is equal to or finer than the dot pitch of the CRT display section 3. Further, the optical fiber layer 10 has one surface shaped into a curved shape corresponding to the display surface 4 so as to be in close contact with the display surface 4, and the other surface so as to be in close contact with the back surface 5 of the tablet input section 2. It is formed into a flat shape. Therefore, one end 12 of each optical fiber 11 constituting the optical fiber layer 1o is in contact with the display surface 4, and the other end 13 is in contact with the back surface 5.

With such a configuration, the information 7 displayed on the display surface 4 is transmitted to the corresponding optical fiber 11 of the optical fiber layer 10.
The user is guided to the sensitive area 7a of the tablet input unit 2. Therefore, regardless of the position of the operator who confirms the information 7, the operator can place the information 7 on the sensitive area 7a.
, and there is no need to input instructions for different positions on the tablet input section 2. Information displayed near the edge of the display surface 4, where the distance from the tablet input unit 2 is large, can also be input with certainty, so compared to conventional input/output devices,
The number of input items can be significantly increased.

[Effects of the Invention] As explained above, in the input/output device of the present invention, the information displayed on the display surface of the CRT display section is guided to the tablet input section by the optical fibers passing through the optical fiber layer.
The location of the information visible on the tablet input remains the same even if the operator's location is different. Therefore, it is possible to reliably input instructions to the part of the tablet input section that corresponds to the information displayed on the display screen.
