Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a ticket vending machine using an infrared touch panel or an ultrasonic touch panel.
[0002]
[Prior art]
Conventionally, a ticket vending machine has been used that displays the amount of money from the back of the push button using an LED or the like and issues a desired ticket when the button of a predetermined amount is pressed. Recently, an ultrasonic touch panel or an infrared touch panel is used. Is displayed on the LCD display surface, the amount of the ticket is displayed on the touch panel surface with the backlight, and when the finger is placed at the desired amount, the amount can be entered without contact (of course, contact is possible) Has been.
[0003]
Such a touch panel ticket vending machine will be described with reference to FIGS.
FIG. 10 shows a monetary amount display surface on which an ultrasonic or infrared touch panel is arranged. When a finger is brought into the charge display area, the presence of the finger is detected by the ultrasonic wave or infrared ray, The displayed amount is input and a ticket corresponding to the amount is issued.
[0004]
FIG. 11 is a diagram for explaining an ultrasonic touch panel.
An X-oscillator 1 is arranged at the left corner of the X side of the rectangular frame of the touch panel, and an X-vibrator 2 is arranged at the left corner of the X side opposite to the X side. Has been placed. A Y-oscillator 3 is arranged at the lower right corner of the Y side of the rectangular frame, and a Y-vibrator 4 is arranged at the lower left corner of the Y side opposite to the Y side. 8 is arranged. The ultrasonic wave generated from the X-oscillator 1 propagates through the reflection array 5, is bent at a right angle by each element of the reflection array 5, propagates toward the opposite X side, and is bent at a right angle by the reflection array 6. It propagates through and is received by the X-pendulum 2. Similarly, the ultrasonic wave generated from the Y-oscillator 3 propagates through the reflection array 7, is bent at a right angle by each element of the reflection array 7, propagates toward the opposite Y side, and is bent at a right angle by the reflection array 8. It propagates in the lever and is received by the Y-pendulum 4.
[0005]
As shown in the figure, among the ultrasonic waves generated from the X-oscillator 1, there is a time difference between the ultrasonic wave S1 propagating through the shortest distance and the ultrasonic wave S2 propagating through the longest distance. The time difference is used as a position signal in the X direction. For example, when a finger touches point A, a part of the ultrasonic wave is absorbed and attenuated, and the position of the finger in the X direction is determined by receiving this signal. Similarly, in the Y direction, the ultrasonic wave is absorbed by the finger, and the position of the finger in the Y direction is determined by receiving this signal. Thus, the position coordinates (X, Y) of the finger are detected, and this can be used as a key input.
[0006]
FIG. 12 shows an example of an infrared touch panel.
An infrared emitter 11 is disposed on the X side of the rectangular frame, an infrared receiver 12 is disposed on the opposite X side, an infrared emitter 13 is disposed on the Y side of the rectangular frame, and an infrared ray is disposed on the opposite Y side. A light receiver 14 is disposed, and infrared light is emitted from the infrared light emitters 11 and 13 toward the opposite side, and is detected by the infrared light receivers 12 and 14 on the opposite side. In such a structure, for example, when a finger is placed at point A in the figure, the infrared rays in that portion are blocked and cannot be detected, so that the coordinates (X, Y) of that position can be keyed in as an address. .
[0007]
[Problems to be solved by the invention]
By the way, when such a touch panel type ticket vending machine is installed, a phenomenon has occurred in which an amount different from the amount desired by the purchaser is erroneously input. Therefore, when the cause was investigated by installing a video camera or conducting interviews, etc., it was found that erroneous input was mainly in the following cases.
(1) A case where the amount of money at the position where the finger first touched is input in order to move the finger to the position of the target amount of money by tracing on the touch panel.
(2) A case where a finger touches the position of 530 yen in FIG.
(3) A case in which another part of the hand touches an undesired amount area first.
[0008]
An object of the present invention is to provide a touch panel ticket vending machine that can prevent a ticket that is not desired by the person from being issued.
[0009]
[Means for Solving the Problems]
According to the present invention, in a ticket vending machine that issues a ticket by selecting one amount display area from among a plurality of amount display areas from an infrared or ultrasonic touch panel, a detection signal obtained from the touch panel continues longer than a threshold value. Control means for determining the amount display area selected on the condition and issuing a ticket, invalidating the detection signal whose duration is shorter than the threshold, and selling the amount display area for the detection signal whose duration is longer than the threshold It is characterized by that.
The present invention also includes a control means for comparing the position where the touch panel is turned on and the position where the touch panel is turned off, on the condition that the turned-on position and the turned-off position are within the same amount display area. It is characterized by.
Also, the present invention is characterized in that each money amount display area peripheral area is made insensitive and is made a non-detection area to prevent erroneous input due to vertical parallax.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below.
As described above, in a ticket machine using an ultrasonic touch panel or an infrared touch panel, when a finger is moved on the touch panel surface, this is detected and operated, so even if it is a little time, other than the position of the desired amount of money If there is a finger, the position will be detected and input, leading to (1) erroneous input due to tracing, (2) erroneous input due to vertical parallax, and (3) erroneous input due to other parts. It was found that a ticket different from the desired ticket was issued.
[0011]
First, (1) a method for preventing an erroneous input by tracing the touch panel surface and (3) a method for preventing an erroneous input by another part will be described.
An error input that traces on the touch panel surface means that the finger is moved on the touch panel surface, moved from that position to the desired amount area, and stopped and entered in the desired amount area. However, it is considered that the position where the finger was first placed on the touch panel surface or the position in the middle of moving the finger is input. In this case, it is considered that the time that the finger stays at each position until reaching the position of the desired amount of money is short. Therefore, when it is detected that there is a finger on the touch panel surface, it is handled as an input signal only when the detection signal in one monetary amount display area continues for a certain period of time so that the detection signal is not immediately input. By doing so, erroneous input due to tracing can be prevented.
[0012]
In addition, erroneous input by other parts is considered to be short when the part other than the finger indicating the amount of money is touching the touch panel surface, so input only when the detection signal in one amount display area continues for a certain period of time. If it is handled as a signal, it is possible to prevent erroneous input in the same manner.
[0013]
In FIG. 1, the horizontal axis indicates the position on the touch panel surface, the vertical axis indicates the signal detection time, and the input is performed when the detection time is equal to or greater than the threshold value T1.
Conventionally, the detection time threshold is extremely short, and for example, input is performed at a threshold T0 or more. Therefore, as shown in FIG. 1, when the finger reaches the desired position P4 by tracing the positions (same amount display areas) P1, P2, and P3, the position P1 was erroneously input. By increasing the detection time threshold to T1, the signals at the positions P1, P2, and P3 become invalid, and the input is performed at the position P4, thereby preventing erroneous input due to tracing.
[0014]
FIG. 2 shows a method of preventing erroneous input by other parts. When a signal is detected from the position P3 and a desired position P4, in this case, when the signal detection at the position P3 is earlier, the threshold value is T0 as in the prior art. If so, the position P3 has been input, but in the present invention, by increasing the threshold value to T1, the signal at the position P3 becomes invalid, the position P4 is input, and erroneous input by other parts can be prevented.
[0015]
FIG. 3 is a diagram showing another example of preventing erroneous input due to tracing.
When the touch panel is traced, as shown in FIG. 3A, an operation is performed in which the finger is brought to the touch panel at the position P1 and moved to release the finger at another position P2. In this case, the position P1 where the finger touches the touch panel 10 is different from the position P2 where the finger is separated. Therefore, the position P1 where the finger is touched is compared with the position P2 where the finger is separated, and if the two positions are different, there is a trace, which is invalidated. On the other hand, as shown in FIG. If the position where the finger touches the position 10 and the position where the finger is released are the same, erroneous input due to tracing can be prevented if the position is valid.
[0016]
Next, prevention of erroneous input due to vertical parallax will be described.
For example, as shown in FIG. 4, an erroneous input due to vertical parallax results in an attempt to hold a finger in the desired amount B area and a finger is placed in the amount A area, and a ticket with an undesired amount A is issued. Is the case.
[0017]
The vertical / horizontal lines in FIG. 5 represent infrared rays on the touch panel surface, and the thick line frame represents the same amount display area. Conventionally, this is detected when a finger is placed in a large area that almost covers the same amount display area as in the area S1. For this reason, in the case shown in FIG. 4, even if a finger is slightly applied to the amount area A, this is detected and erroneously input. However, as shown in area S2 of FIG. By making the area insensitive and making it a non-detection area, it is not detected when a slight finger is placed on the amount display area, and erroneous input due to vertical parallax can be prevented.
[0018]
FIG. 6 is a block diagram showing the configuration of the ticket vending machine of the present invention.
As described above, the touch panel 10 is of the ultrasonic type or infrared type, and the detection signal is taken into the arithmetic processing control device 20 and processed as described with reference to FIGS. When the signal is detected, the ticket issuing device 30 operates to issue a ticket.
[0019]
Next, processing performed by the arithmetic processing control device 20 will be described below.
FIG. 7 is a diagram illustrating a flow of ticket issuing processing when a signal obtained from the touch panel is equal to or greater than a threshold value T1.
First, it is determined whether or not the touch panel is on. If the touch panel is on, the detection signal is compared with the threshold time T1 (steps 1 and 2). Next, if the detection signal is equal to or greater than the threshold time T1, ticket issuing processing is performed (steps 3 and 4), and if the detection signal is shorter than the threshold time T1, ticket issuing processing is not performed. By this process, when the detection time is short, the ticket issuing process is not performed, so that it is possible to prevent an incorrect boarding ticket from being traced or other parts from being issued.
[0020]
FIG. 8 is a diagram showing a processing flow in which the detection range of the touch panel is narrowed.
First, it is determined whether or not the touch panel is on, and the position coordinates where the touch panel is on are acquired (steps 11 and 12). Next, it is determined whether or not the turned-on position is within the narrowed detection area. If it is within the area, ticketing processing is performed (step 14), and if it is outside the area, ticketing processing is not performed. Since the detection range is narrowed by this process, it is possible to prevent an erroneous ticket from being issued due to the vertical parallax.
[0021]
FIG. 9 is a diagram for explaining a flow for issuing a ticket when the position where the finger touches the touch panel and the position where the finger is separated are in the same amount area.
First, it is determined whether or not the touch panel is on, and the position coordinates where the touch panel is on are acquired (steps 21 and 22). Next, it is determined whether or not the finger has been removed from the touch panel, and the position coordinates that have been turned off are acquired (steps 23 and 24). Next, the acquired position coordinates that are turned on and the position coordinates that are turned off are compared, and if they are within the same amount area, ticketing processing is performed, and if they are different areas, ticketing processing is not performed. By this process, it is possible to prevent an incorrect boarding ticket from being issued by tracing.
[0022]
