Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevator display device that displays elevator operation information and passenger service information installed in an elevator car and at a landing.

Recently, dot displays using matrix control, liquid crystal matrix displays, collective cathode ray tube displays, plasma displays, etc. have been put into practical use, and large amounts of text and graphic information can be displayed on relatively large screens. In the case of elevators, a display device is installed at one landing within the car to display operation information such as the elevator position and direction, in-building service information for passengers, etc., either all at once or selectively.

In general, elevator display devices are arranged face-to-face for each elevator, especially in landings, where multiple elevators are installed, and at least for each elevator installation surface.
It is necessary to arrange the display device. Further, in a car, although it is generally arranged on the wall above the passenger door, it has become necessary to provide a driving information display device opposite the passenger door for people with disabilities such as wheelchairs. However, the above-mentioned display devices are generally expensive, and arranging a large number of them has not been adopted due to cost constraints.

This invention has been made in view of the above points, and is an elevator display device that allows displays to be viewed from the blind spots of the display device, that is, from various angles, without providing a large number of display devices in the hall and in the car. It provides:

27 third input.

Next, the operation of this embodiment will be explained.

First, if none of the hall call registration buttons 7.8 are pressed, the call signal processing circuit 11 generates the rising registration signal 7.8. ,
8. Also falling registration signal 711. ．． 8ゎ is not output and it is 1L
'', the outputs of OR gates 21 and 22 are both “L”, and the output of NAND gate) 23°25 is II
However, since the outputs of the inverters 29 and 24 are both 11T'', the output of the NAND gate 26 is L'', the output of the three-man NAND gate 2T is H11, and the output of the NAND gate 28 is H11. The output is L''.

That is, in this state, the selector 15 selects the data signal 12a of the data source/main circuit 12 and outputs it to the display section 13, so that the display screen 5 displays a normal display as shown in FIG. 3(a). It becomes.

Next, the passenger presses the hall call registration button 8 on the opposite side of the display screen 5.
When the up button is pressed, the up button signal 8° causes the call signal processing circuit 11 to set the up registration signal 8ff to the hall call registration button 8 to H'', so the output of the OR gate 22 becomes H'', and the NAND The output of gate 25 is Ill
It becomes Ln. On the other hand, since the output of the inverter 24 becomes L', the output of the NaND gate 26 becomes 'H',
The output of the NAND gate 23 remains at H''. Therefore, the output of the NAND gate 28 becomes 1H'',
Since the output of the human-powered NAND gate 2T is 1L,
The selection signal 16a of the NAND gate 28 is held at "H".

As a result, the selector 15 selects the input end B, so the output data of the data converter 14 is input to the display section 13, and the display screen 5 displays a regular screen as shown in FIG. 3(b). A symmetrical screen is displayed, and the image of the display screen 5 is reflected on the mirror 6 installed above the hall call registration button 8, and the screen becomes a regular screen as shown in FIG. 3 (al).

Furthermore, if another passenger subsequently presses the up or down button of the hall call registration button T on the display screen 5 side, the up registration signal 7T1 or the down registration signal 7D of the hall call registration button 7 becomes rt"ic. , the output of the inverter 24 is @
Since it is L''', the output of the NAND gate 23 is 1H''
The output of the inverter 29 remains "T,"
K, and the output of the NAND gate 25 also becomes AI'', but
Since the output of the 3-person NAND gate 2T is 6L'', N
The selection signal 16a of the AND gate 28 holds "H",
The display on the display screen 5 does not change.

Next, when the up or down button of the hall call registration button 7 on the display screen 5 side is pressed in a state where none of the hall call registration buttons 1 and 8 are registered, a rise registration signal T is generated.

Or, the falling registration signal 7I becomes "■(", and the output of the 0 gate 21 becomes 1H", at this time, the rising registration signal 8°,
Since the falling registration signal 8D is L', the output of the zero gate 22 is L', so the output of the inverter 24 is 1I'' and the output of the NAND gate 23 is L'', and the three-man NA
The output of the ND gate 21 becomes ")T", and the NAN
The output of the D gate 25 is the output of the inverter 29 which is 1L"
Therefore, the selection signal 16a of the NAND gate 2B is held at "L", and the normal screen is displayed on the display screen 5.

Here, even if the hall call registration button 8 on the mirror 6 side is pressed and the ascending registration signal 8 or descending registration signal 8D becomes "H" and the output of the OR gate 22 becomes "H", the inverter 29 Since the output of is “L”, NAND gate 25
The output cannot become 'L', and the selection signal 16a of the NAND gate 28 maintains the 'L' state.

In this embodiment, when the hall call registration button 7 on the side of the display screen 5 is pressed first, the regular screen is displayed on the display screen 5, and the hall call registration button on the opposite side of the counter pressure display screen 5 is pressed. When the button 8 is pressed first, the screen display on the display screen 5 becomes a symmetrical image, and the mirror 6 on the side of the pressed hall call registration button 8
This allows you to see the regular image.

FIG. 5 shows another embodiment of the present invention, in which 30 is a car, 31 is a car door, 32 is a car call registration button, 33 is a car call registration button for disabled people in wheelchairs, and 34 is a car door for disabled people in wheelchairs. , 35 is a display screen similar to the display screen 5 of FIG. 1 provided above the car door 31, and 36 is a mirror provided on the wall facing the display screen 350.

In this embodiment, the display functional configuration of the elevator of the present invention is as follows: The hall call registration button T shown in FIG.

All you have to do is replace the hall call registration button 8 with the call registration button 32 and the car call registration button 33 for disabled people in wheelchairs.
The details are omitted.

Normally, since the car call registration button 32 is pressed, a normal image is displayed on the display screen 35, but when the car call registration button 32 is not pressed, the wheelchair-disabled person 34 enters the car 30. When the user gets on the car and presses the wheelchair-disabled car call registration button 33, the display screen 35 displays the regular image and the image of left and right symmetry, and the mirror 36 installed on the wall opposite the display screen 35 displays A symmetrical image of the screen 35 is reflected, and as a result, a regular image can be seen on the mirror 361C.

As explained in detail above, the elevator display device of the present invention can be used in a hall by simply installing the display screen on one wall, and for passengers who stand in the opposite direction to the display screen and whose blind spot is the display screen. By making the display screen visible in the mirror, and inside the car, by reflecting the normal display screen on the car door side in the mirror on the opposite wall, it is possible to provide a service that allows disabled people in wheelchairs to see the same pressure. There is no need to provide multiple display devices.

In addition, when applied inside the car, the display screen is displayed symmetrically with the regular screen when there are no passengers, because when the car door opens, the display screen inside the car can be seen through the mirror by passengers at the landing. This also has the effect of providing information on elevator operation to passengers in the hall.
