Abstract

PROBLEM TO BE SOLVED: To accurately touch a position by providing an input control means for preferentially inputting a signal in an adjacent position when a position touching a protection face straddles the user side position and the position adjacent to a side separated from a user. SOLUTION: A controller which controls an automatic ticket issuing machine A and which is formed with a microcomputer having an input control means as the center displays the prescribed contents of an account key group or a station name group. The controller controls an intersection (X1, Y1) on the side detached from the user (so that it is preferentially inputted when the intersection (X1, Y2) on the user side and the intersection (X1, Y1) adjacent to the side detached from the user, which are viewed form the user side, are simultaneously touched. Thus, the position which the user actually desires is accurately touched.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a touch panel type input device of a processor operated by a user such as an automatic ticket vending machine or an ATM.

[0002]

2. Description of the Related Art Conventionally, an automatic ticket vending machine capable of displaying a group of account buttons and a group of station names on a display screen and issuing a ticket when the target account button or station name is touched (pressed). Is proposed.

As a processing machine equipped with a touch panel type input device operated by a user, in addition to the above-mentioned automatic ticket vending machine, there is station service equipment such as a transit adjustment machine and an automatic commuter pass issuing machine. There is. Further, such a touch panel type input device is widely used in various fields, as is also used in ATM.

This touch panel type input device is an LCD
A protective surface made of a transparent material, such as glass, is provided above the display screen such as a CRT screen at a distance of 5 to 10 mm. Then, when a position corresponding to the display content on the display screen is touched on the protective surface, a signal (data) corresponding to the display content can be input. That is, the touch position on the protective surface is configured so that the input position is specified by detecting the intersection position of the X-axis direction which is the horizontal axis direction and the Y-axis direction which is the vertical axis direction by a sensor such as a photo sensor. .

[0005]

However, in the above-mentioned conventional input device, there is a gap between the display screen and the protective surface.
Since the interval is about 10 mm, the touch position may be different from the desired touch position. For example,
When the display screen is not viewed from directly above, that is, when the display screen is viewed obliquely, a position different from the desired touch position may be touched.

When the touch position is displaced as described above, a signal different from a desired signal is input, and an undesired ticket is issued.

Therefore, the present invention has been made in order to eliminate the above-mentioned drawbacks, and an object thereof is to provide an input device in which a touch position is accurately made.

[0008]

In order to achieve the above-mentioned object, an input device according to the present invention has a transparent protective surface at a predetermined interval above a display screen, and display contents on the display screen. In the input device configured to touch the position of the protective surface corresponding to the specific position and input the signal corresponding to the specific position, the position where the protective surface is touched is the user side position and the user. When straddling an adjacent position on the far side, an input control means for preferentially inputting a signal at the adjacent position is provided.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view when the input device a is applied to a slant type automatic ticket vending machine A having an inclined customer service surface. Therefore, the input device a is provided so as to be inclined as shown in the drawing.

In the figure, reference numeral 1 is a display screen composed of a CRT screen, which is mainly formed by a microcomputer which controls the automatic ticket vending machine A and which also serves as an input control means of the present invention. The control unit is configured to display predetermined contents such as a group of account buttons or a group of station names.

In the figure, 2 is a display surface (top surface) of the display screen 1.
Is a protective surface for protecting the display screen 1 provided at a predetermined distance from, for example, 5 to 10 mm,
It is made of transparent and hard glass. Of course, the protective surface 2 may be made of transparent plastic.

Similar to a known touch panel, a large number of photosensors are provided around the protective surface 2 in the X-axis direction and the Y-axis direction so that the touch position on the protective surface 2 can be detected. It is configured. Note that the touch position detection is not limited to the photo sensor type as described above, and the protection surface 2
Other well-known ones such as providing a transparent conductive film on the upper surface of can also be adopted.

Hereinafter, referring to the explanatory view of FIG. 2, FIG.
The control operation when the user a shown in (in FIG. 1, only the eyes of the user are shown) inputs is described. This FIG. 2 is a part of the upper surface of the protective surface 2, and the cells shown by the solid line are not actually shown on the protective surface 2, but are specified by the photosensors provided in the X-axis direction and the Y-axis direction. Shows the touch position. Further, in FIG. 2, "b" represents the finger of the user "a".

Now, the user a has an intersection (X1, Y1) between the X1 position in the X-axis direction and the Y1 position in the Y-axis direction on the display screen 1.
It is assumed that the user is trying to touch the content displayed at the specified location.

In this case, the position of the eyes of the user a is not on the vertical line of the intersection (X1, Y1) as shown in FIG. 1, and when the intersection is viewed obliquely, The intersection point (X1, Y1) on the user side of the actual intersection point (X1, Y1)
It seems to be displayed on Y2). Therefore, the finger b of the user a tends to be touched below the intersection (X1, Y1) or above the intersection (X1, Y2) in FIG.

For this reason, the controller (not shown) operates at the intersection (X
When 1, Y1) and (X1, Y2) are touched at the same time for a predetermined time, the intersection point (X1, Y) farther from the user a
1) is controlled so that the signal is input as if touched. That is, when viewed from the user a side, the controller simultaneously touches the intersection (X1, Y2) on the user a side and the adjacent intersection (X1, Y1) on the side away from the user a. Controls so that the intersection (X1, Y1) on the side away from the user a is preferentially input.
Therefore, the position actually desired by the user a is accurately touched.

In the above example, the input device a is incorporated in the automatic ticket vending machine a.
It may be incorporated in another processing machine such as M.

[0018]

In the input device according to the present invention, when the position where the protective surface is touched extends over the user side position and the adjacent position on the side away from the user, the signal at the adjacent position is given priority. Since the input control means for inputting by inputting is provided, erroneous input can be effectively prevented.

Claims (1)

[Claims] 1. A transparent protective surface is provided above a display screen at a predetermined interval, and a position of the protective surface corresponding to a specific position of display content on the display screen is touched to correspond to the specific position. In the input device configured to input the signal, when the position touching the protective surface straddles the user side position and the adjacent position on the side away from the user, the signal at the adjacent position is prioritized. An input device characterized in that input control means for inputting is input.
