・ Mode switching function A
When the wheelchair user boarding determination unit 21 determines that there is a wheelchair user boarding the car from the hall side, the mode switching function A is registered by the destination floor button of the wheelchair-specific car operation panel 2. This is a function for switching from the video display mode to the mirror mode when or before the door 4 opens on the floor.

  This function allows a wheelchair user to look at the mirror of the mirror-type display 6 without changing the direction from the state where the mirror-type display 6 is facing in the car (the hall side). And checking the distance between the open door and the wheelchair), you can move back to the hall without falling behind the door or people.

・ Mode switching function B
The mode switching function B is a function that immediately switches from the video display mode to the mirror mode when it is determined by the wheelchair user boarding determination unit 21 that there is a wheelchair user getting into the car from the hall side. is there.

  With this function, when a wheelchair user gets into the car, he looks at the mirror of the mirror type display 6 (checking the state of the hall and the distance between the open door and the wheelchair) You can move forward and move into the car as if not.

  However, this mode switching function B is not an essential element. For example, the elevator administrator installs the function when it desires, and does not install it when it does not.

・ Mode switching function C
When the wheel switch user call determination unit 22 determines that there is a call registration by the wheelchair dedicated landing button 12 on the floor, the mode switching function C is performed when the door 4 is opened on the floor or before that. This is a function for switching from the video display mode to the mirror mode.

  This mode switching function C can be used as an alternative to the mode switching function B described above. For example, in the above-described mode switching function B, it is impossible to recognize that there is a wheelchair user trying to get into the car and switch to the mirror mode unless the door 4 is opened. A person cannot use the mirror type display 6 as a mirror from the time when the door 4 starts to open.

  Next, an example of display switching of the mirror type display 6 by the various mode switching functions described above will be described with reference to FIGS.

First Display Switching Example FIG. 5 shows a first display switching example. In the video display mode, the display control unit 23 turns on the backlight 6b so that the mirror-type display 6 can display a video such as signage in the entire region. The backlight 6b of the mirror type display 6 is turned off so that the image 6 does not display an image.

  According to the first display switching example, the wheelchair user can use the entire area of the mirror type display 6 as a mirror in the mirror mode.

  In the first display switching example described above, an example in which the backlight 6b is turned off to realize the mirror mode has been described. However, the mirror mode does not turn off the backlight 6b. Both can be realized. For this purpose, for example, a black image may be projected on the screen of the mirror type display 6 so that the mirror type display 6 can be used as a mirror, or the mirror type display 6 can be used as a mirror. Change the parameters for setting the display characteristics of the display 6 (display brightness, contrast, etc.) to darken the screen (for example, set the brightness level to 0 or maximize the ratio of black to white) It is also possible to set the contrast.

Second Display Switching Example FIG. 6 shows a second display switching example. In the video display mode, the display control unit 23 turns on the backlight 6b so that the mirror-type display 6 displays an image such as signage in the entire area. The backlight 6b of the mirror type display 6 is dimmed so that it can be used as a mirror while displaying an image on the display 6 (ie, the brightness is reduced to a predetermined value instead of turning off the backlight 6b). )

  According to the second display switching example, the wheelchair user can use the entire area of the mirror type display 6 as a mirror in the mirror mode, and when a person other than the wheelchair user is in the car, A person other than the user can continuously view the signage or the like in the entire area of the mirror type display 6.

Third Display Switching Example FIG. 7 shows a third display switching example. In the video display mode, the display control unit 23 displays the image such as signage in the entire area in the video display mode. However, in the mirror mode, a part of the mirror type display 6 is mirrored. The image displayed on the mirror type display 6 is reduced so that it can be used as

  According to the third display switching example, the wheelchair user can use a part of the mirror type display 6 (for example, the lower half of the region) as a mirror in the mirror mode, and is not a wheelchair user. If the person is in the car, the person other than the wheelchair user should continue to view the video of the signage etc. reduced in a part of the mirror type display 6 (for example, the upper half area). Can do. When switching to the mirror mode, the size of both the mirror and the video is reduced. However, compared to the above-described second display switching example, the mirror-type display 6 has the original good quality mirror and video. it can.

-Example of 4th display switching In FIG. 8, the example of 4th display switching is shown. In the video display mode, the display control unit 23 displays the video such as signage in the entire area in the video display mode. However, in the mirror mode, instead of the video such as the signage, the door control camera 5 may be displayed on a part of the area of the mirror type display 6, and a message and guidance information to be transmitted to the wheelchair user may be displayed on a part of the mirror area where the image is not displayed. Good.

  As an example of the message, for example, “please be careful not to hit people on the hall side”. Examples of the guidance information include information indicating the direction in which the wheelchair user should be guided, such as “→” and “←”. For example, as described above, when the wheelchair user gets out of the car (or gets on the car), the image is analyzed through the door control camera 5 and the position of the wheelchair becomes a reference. If it is determined that it is too far to the left from the position, “→” is displayed as guidance information. On the other hand, if it is determined that it is too far to the right, “←” is displayed as guidance information. Let

  According to the fourth display switching example, when the wheelchair user gets out of the car (or gets in the car), the user sees not only the mirror but also the image of the hall reflected by the door control camera 5. Can provide a sense of security to wheelchair users. At the same time, by displaying messages and guidance information in a part of the mirror area, it is possible to alert the wheelchair user and guide the wheelchair user in the appropriate direction, further enhancing safety. be able to.
