Next, each configuration of the card reader 100 with a liquid crystal panel will be described.
A card reader 101 (an example of an authentication information reading device) is brought close to a card (hereinafter referred to as an authentication card) having an IC tag in which authentication information 113 (for example, registration ID [Identifier] of the user 206) is recorded. The short-distance wireless communication (for example, communication by RFID [Radio Frequency Identification]) and the authentication information 113 is read from the IC tag of the authentication card.
The liquid crystal panel 102 (an example of a display panel, a liquid crystal screen, and a touch panel) has a characteristic that a plurality of images are displayed in the same time zone, and images that are visually recognized are different depending on a difference in the viewing direction. It is arranged on the front surface of the card reader 100 with a liquid crystal panel in such a direction that a different image is viewed in the lower line-of-sight direction 202.
The camera 103 (an example of a width sensor and a height sensor) is provided in front of the card reader 100 with a liquid crystal panel, and is a still image or a moving image (hereinafter referred to as the front) in front of the card reader 100 with a liquid crystal panel (particularly, the liquid crystal panel 102). Image 114).
In the memory 105 (for example, RAM [Random Access Memory], main storage device, cache, buffer) (image storage unit), guidance 111 for adults (first image) and guidance 112 for children (second image) are stored in advance. ) Is stored.

The CPU 104 (central processing unit) functions as a panel control unit 121, a user determination unit 122, and an authentication request unit 123, and controls the card reader 101, the liquid crystal panel 102, the camera 103, and the memory 105.
The user determination unit 122 causes the camera 103 to capture the front image 114, inputs the captured front image 114 from the camera 103, and based on the input front image 114, the card reader with a liquid crystal panel 100 (particularly, the liquid crystal panel 102). ), The width and height of the user 206 in front of is measured. Then, based on the measurement result, the user determination unit 122 determines whether the user 206 is using the wheelchair 207 and whether the user 206 using the wheelchair 207 is an adult or a child. judge.
The panel control unit 121 displays the adult guidance 111 stored in the memory 105 on the liquid crystal panel 102 as a top view screen, and displays the child guidance 112 stored in the memory 105 on the liquid crystal panel 102 as a bottom view screen. To do. In addition, when the user determination unit 122 determines that the user 206 is an adult using the wheelchair 207, the panel control unit 121 displays the adult guidance 111 on the liquid crystal panel 102 as a preview screen.
The authentication request unit 123 inputs the authentication information 113 read by the card reader 101, outputs the input authentication information 113 to the authentication device 190, and requests an authentication process for the authentication information 113.

  Information used by the card reader 100 with a liquid crystal panel, such as the authentication information 113, the front image 114, and the determination result of the user determination unit 122, is stored in the memory 105 (not shown).

FIG. 4 is a flowchart showing an authentication method of authentication system 199 in the first embodiment.
An authentication method of authentication system 199 in the first embodiment will be described below with reference to FIG.
Here, it is assumed that the camera 103 of the card reader with a liquid crystal panel 100 is photographing the front of the card reader with a liquid crystal panel 100 (particularly, the liquid crystal panel 102) continuously or at short intervals. However, the camera 103 may shoot only when the user 206 is in front of the card reader 100 with a liquid crystal panel. For example, when the card reader 100 with a liquid crystal panel includes a human sensor (for example, an infrared sensor) and the human sensor detects that the user 206 appears in front of the card reader 100 with a liquid crystal panel, While the user 206 is detected by the time or the human sensor, the camera 103 may perform shooting.

<S110: User detection processing>
First, it is determined whether or not the user 206 appears in front of the card reader 100 with a liquid crystal panel.
For example, the user determination unit 122 includes a current front image 114 captured by the camera 103 and an image captured when the user 206 is not in front of the card reader 100 with a liquid crystal panel (hereinafter referred to as a sample image). Each pixel is compared, and based on the comparison result, it is determined whether or not the user 206 appears in front of the card reader 100 with a liquid crystal panel. For example, the user determination unit 122 determines that the user 206 appears in front of the card reader 100 with a liquid crystal panel when the number of pixels different between the front image 114 and the sample image is equal to or greater than a predetermined threshold. Further, for example, the card reader with a liquid crystal panel 100 includes a human sensor (for example, an infrared sensor), and the user determination unit 122 indicates that the user 206 has appeared in front of the card reader with a liquid crystal panel 100 from the human sensor. The determination may be made based on whether a detection signal is input.
The user detection process (S110) is repeated until the user 206 appears in front of the card reader 100 with a liquid crystal panel.

<S120: Guidance display processing>
When it is detected in S110 that the user 206 appears in front of the card reader 100 with a liquid crystal panel, the panel control unit 121 displays a predetermined guidance on the liquid crystal panel 102 by a predetermined screen control method.
Thereby, the user 206 can know the information of guidance.
Details of the screen control method will be described later.

<S130: Authentication processing>
Here, the authentication card is brought close to the card reader 101 by the user 206.
The card reader 101 reads the authentication information 113 from the authentication card, the authentication request unit 123 inputs the authentication information 113 read by the card reader 101, and outputs the input authentication information 113 to the authentication device 190.
The authentication device 190 includes a database device in which the ID of the user 206 permitted to enter and exit the place where the entrance is restricted by the authentication system 199 is stored in advance as registration information, and is input from the authentication request unit 123. The authentication information 113 and the registration information stored in the database device are compared to search for registration information that matches the authentication information 113.
If there is registration information that matches the authentication information 113, the authentication device 190 sets the authentication result to “authentication OK (admission permission)” and notifies the door control device 180 of the admission permission.
If there is no registration information that matches the authentication information 113, the authentication device 190 sets the authentication result to “authentication NG (no admission permitted)” and does not notify the door control device 180 of admission permission. In this case, the door opening process (S140) is not executed.
Further, if the authentication information 113 is not read by the card reader 101 after waiting for a predetermined time, the authentication request unit 123 sets the authentication result to “authentication NG (admission not permitted)”. In this case, the door opening process (S140) is not executed.

<S140: Door opening process>
In the authentication process (S <b> 130), when there is an admission permission notification from the authentication device 190 to the door control device 180, the door control device 180 opens the door 200.
Thereby, the user 206 can enter the place where entrance is restricted.

FIG. 5 is a flowchart illustrating the screen control method according to the first embodiment.
The screen control method in the guidance display process (S120) will be described below with reference to FIG.

<S121>
The panel control unit 121 displays the adult guidance 111 stored in the memory 105 on the liquid crystal panel 102 as a top view screen.
Thereby, the card reader 100 with a liquid crystal panel can show the adult-oriented guidance 111 to the adult user 206 who sees the liquid crystal panel 102 from diagonally upward.

<S122>
The user determination unit 122 inputs the front image 114 taken by the camera 103 and determines whether the user 206 is using the wheelchair 207 based on the input front image 114.
At this time, the user determination unit 122 identifies the range in which the user 206 is shown from the front image 114, and sets the width of the identified range as the width of the user 206 (hereinafter referred to as the detection width 204). Compare for comparison). And the user determination part 122 determines with the user 206 using the wheelchair 207, when the detection width 204 is more than the threshold value for width comparison, and the detection width 204 is less than the threshold value for width comparison. In this case, it is determined that the user 206 is not using the wheelchair 207.

FIG. 6 is a diagram illustrating an example of the front image 114 in the first embodiment.
For example, when the user 206 is using the wheelchair 207, the user 206 appears in the front image 114 as shown in FIG. The user 206 who is using the wheelchair 207 is wider than the user 206 who is not using the wheelchair 207 by the amount of the wheelchair 207.
Therefore, in S122, the user determination unit 122 compares each pixel of the sample image that does not show the user 206 and the front image 114, and the user 206 shows a different range between the sample image and the front image 114. It is determined as a range, the number of pixels in the horizontal direction of the determined range of the user 206 is calculated as a detection width 204, and the user 206 uses the wheelchair 207 by comparing the calculated detection width 204 with a threshold for width comparison. It is determined whether or not. As a threshold for width comparison, a value (number of pixels) corresponding to a width (for example, 550 mm) slightly narrower than the width (600 mm to 700 mm) of a wheelchair generally used is used.

<S123>
When it is determined in S122 that the user 206 is using the wheelchair 207, the user determination unit 122 determines whether the user 206 using the wheelchair 207 is an adult or a child based on the front image 114. judge.
At this time, the user determination unit 122 determines the height (number of pixels) of the range in which the user 206 is identified in S122 as the height (sitting height) of the user 206 (hereinafter referred to as the detected height 205). Compare with threshold (for height comparison). Then, the user determining unit 122 determines that the user 206 is an adult when the detected height 205 is equal to or higher than a height comparison threshold, and the detected height 205 is less than the height comparison threshold. In this case, it is determined that the user 206 is a child.
In FIG. 6, an adult user 206 has a higher detection height 205 than a child user 206 because the sitting height is higher. For the threshold value for height to be compared with the detected height 205, for example, a value (number of pixels) corresponding to a height (for example, 800 mm) that is higher than the average child's sitting height and lower than the average adult's sitting height. Use.

<S124>
When it is determined in S123 that the user 206 is an adult using the wheelchair 207, the panel control unit 121 displays the adult guidance 111 stored in the memory 105 on the liquid crystal panel 102 as a lower view screen.
Thereby, the card reader 100 with a liquid crystal panel can show the adult-oriented guidance 111 to the adult user 206 who is using the wheelchair 207 which sees the liquid crystal panel 102 from diagonally downward.

<S125>
If it is determined in S122 that the user 206 is not using the wheelchair, and if it is determined in S123 that the user 206 is a child using the wheelchair 207, the panel control unit 121 stores in the memory 105. The stored child guidance 112 is displayed on the liquid crystal panel 102 as a lower view screen.
Thereby, the card reader 100 with a liquid crystal panel can show the guidance 112 for children to the child user 206 who sees the liquid crystal panel 102 from diagonally below.

In the first embodiment, the card reader 101 is an example of an apparatus that reads the authentication information 113. The card reader 100 with a liquid crystal panel may include another authentication information reading device instead of the card reader 101 or together with the card reader 101. For example, a biometric authentication device that reads biometric information such as a fingerprint, voice print, iris, vein, and face image of the user 206 as the authentication information 113 or a pressed password is input as the authentication information 113 to the other authentication information reading device. There is a numeric keypad to do.
The camera 103 is an example of a sensor that detects the width and height of the user 206. The card reader with a liquid crystal panel 100 may include other sensors instead of the camera 103 or together with the camera 103. For example, other sensors include an infrared sensor and a pressure sensor that senses the leg position of the user 206 and the wheel position of the wheelchair 207.
Further, the authentication device 190 and the door control device 180 may be built in the card reader 100 with a liquid crystal panel.
In addition, the contents indicated by the guidance (advancement guidance 111 for adults, guidance 112 for children) may be arbitrary information.

  In addition, when the user determination unit 122 determines that the user 206 is using the wheelchair 207 (S122), the panel control unit 121 may turn off the viewing screen displayed in S121. In addition, when the user determination unit 122 determines that the user 206 is using the wheelchair 207 (S122), the panel control unit 121 may not display the top view screen. That is, S121 may be executed on the condition that the user 206 is not using the wheelchair 207 after S122. In this way, power consumption can be reduced by not displaying the top view screen when it is not necessary. On the other hand, by always displaying both the upper and lower screens, if both an adult and a child, or an adult who is not using the wheelchair 207 and a wheelchair user are accompanied, Appropriate guidance can be presented.

  In addition, when the user 206 is an adult using the wheelchair 207, the panel control unit 121 displays guidance for adults using the wheelchair 207 in S124, and the user 206 uses the wheelchair 207. If the child is a child, the guidance for the child using the wheelchair 207 may be displayed in S124. That is, when the user 206 is using the wheelchair 207, the panel control part 121 may display the guidance for wheelchair users.

  In the first embodiment, the following card reader with a liquid crystal display function (card reader 100 with a liquid crystal panel) has been described.

  A card reader with a liquid crystal display function is installed in a building or a condominium, and has a card reader 101 and a liquid crystal display screen (liquid crystal panel 102), and displays guidance for a card reader user.

  The card reader with a liquid crystal display function includes a card reader 101 that reads information stored in an IC card, and a liquid crystal display screen. Further, the card reader with a liquid crystal display function stores guidance 1 (upward view screen) displayed for the upper viewing direction of the liquid crystal display screen and guidance 2 (lower view screen) displayed for the lower view direction of the liquid crystal display screen. And a CPU 104 that displays the display content for the upper view and the display content for the lower view simultaneously and independently on one liquid crystal display screen.

  The liquid crystal display screen is viewed from two different screens: a screen that is displayed when viewed from above (upper view screen) and a screen that is displayed when viewed from below (view screen). It is a liquid crystal display that displays two or more different screens that are sometimes displayed simultaneously and independently on one screen.

The card reader with a liquid crystal display function includes a user determination unit 122 and a panel control unit 121.
The user determination unit 122 determines whether the user 206 is an adult, a child, or a wheelchair user.
The panel control unit 121 displays a dedicated adult guidance (adult guidance 111 for adults) set in advance on a screen displayed when viewed from above the liquid crystal panel 102. The panel control unit 121 is set in advance on a screen displayed when the user determination unit 122 determines that the user 206 is a child or a wheelchair user when viewed from below the liquid crystal panel 102. The dedicated guidance is switched according to the user 206 and displayed.

  When the user determining unit 122 determines that the user 206 is a wheelchair user, the panel control unit 121 is for adults set in advance on a screen displayed when viewed from below the liquid crystal panel 102 or Display dedicated guidance for wheelchair users.

  When the user determining unit 122 determines that the user 206 is a child, the panel control unit 121 is a guidance dedicated to children that is set in advance on a screen that is displayed when the user 206 is viewed from below. (Children guidance 112) is displayed.

The card reader with a liquid crystal display function has the following effects.
Guidance for adults can be seen when viewing the LCD screen from the top view, and guidance for children when viewing from the bottom view direction, so one LCD screen can provide easy-to-understand guidance for both adults and children be able to.
In addition, in order to determine whether the user 206 is a child or an adult using a wheelchair 207 by the width detection sensor (camera 103, user determination unit 122), an adult using the wheelchair 207 is also requested. You can show guidance for adults.

Embodiment 2. FIG.
In the second embodiment, a mode is described in which the card reader 100 with a liquid crystal panel allows the user 206 to select the lower screen without determining the lower screen based on the result of the height determination.
Hereinafter, items different from the first embodiment will be mainly described, and items omitted will be the same as those of the first embodiment.

FIG. 7 is a flowchart illustrating a screen control method according to the second embodiment.
A screen control method in the guidance display process (S120) will be described below with reference to FIG.

<S221>
The panel control unit 121 displays the guidance 111 for adults on the liquid crystal panel 102 as a top view screen in the same manner as in S121.
<S222>
The user determination unit 122 determines whether the user 206 is using the wheelchair 207 in the same manner as S122.
When it is determined that the user 206 is not using the wheelchair 207, the panel control unit 121 displays the child guidance 112 on the liquid crystal panel 102 as a lower view screen (S226).

<S223>
When it is determined in S222 that the user 206 is using the wheelchair 207, the panel control unit 121 displays a selection screen that prompts the user 206 to select either the adult guidance 111 or the child guidance 112. A display screen is displayed on the liquid crystal panel 102. It is assumed that the selection screen is stored in the memory 105 in advance.
For example, the selection screen includes a selection button displayed as “adult” and a selection button displayed as “child”.
A selection screen is visible on the liquid crystal panel 102 for a child 206 or an adult using a wheelchair 207 who is a user 206 viewing the liquid crystal panel 102 from an obliquely lower side.

<S224>
Here, it is assumed that the liquid crystal panel 102 has a touch panel function of acquiring information corresponding to the pressed position as the designation information of the user 206 when the surface is pressed.
The user 206 presses a selection button displayed on the liquid crystal panel 102 to select “adult” or “child”.
The panel control unit 121 inputs information (designated information) selected by the user 206 from the liquid crystal panel 102.

<S225>
When the information input from the liquid crystal panel 102 indicates “adult”, the panel control unit 121 displays the adult guidance 111 on the liquid crystal panel 102 as a preview screen in the same manner as in S124.

<S226>
When the information input from the liquid crystal panel 102 indicates “child”, the panel control unit 121 displays the child guidance 112 on the liquid crystal panel 102 as a lower view screen in the same manner as in S125.

  The process (S223 to S226) for displaying the undersight screen selected by the user 206 is a process of determining whether the user 206 using the wheelchair 207 is an adult or a child (S130) in the first embodiment. It may be executed when accuracy seems to be low. For example, the case where the accuracy of the determination is considered to be low is when the detection height 205 of the user 206 is within a range of 750 to 850 mm, and the user 206 is likely to be an adult or a child. It is. At this time, when the detected height 205 indicates a value greater than 850 mm, S140 is executed and the adult guidance 111 is displayed as a lower view screen, and when the detected height 205 indicates less than 750 mm, S150 is executed and the child is displayed. When the direction guidance 112 is displayed as a lower view screen and the detected height 205 indicates 750 mm or more and 850 mm or less, S223 to S226 are executed.

  Thereby, the card reader 100 with a liquid crystal panel can display an appropriate screen according to the user 206 more reliably on the liquid crystal panel 102.

Embodiment 3 FIG.
