  FIG. 2 shows a case where the display screen 14 of the display 2 is switched to the display state. Since the video (weather forecast video in this example) displayed on the display screen 14 of the display 2 is transmitted through the beam splitter 1, the first surface 8 of the beam splitter 1 can be seen from the boarding space 5 in the elevator car 4. It can be visually recognized by looking. In addition, the region of the beam splitter 1 that does not face the display screen 14 of the display 2 functions as a mirror, and the region that functions as the mirror includes an object that is positioned facing the first surface 8 of the beam splitter 1 (this example The wheelchair user and the closed car door 10) are shown. The beam splitter 1 also has a mirror function in the area where the image on the display screen 14 of the display 2 is displayed. Therefore, in the area where the image on the display screen 14 of the display 2 is displayed, the beam splitter 1 is used. The object located opposite to the first surface 8 (in this example, the wheelchair user and the closed car door 10) is superimposed on the image on the display screen 14 of the display 2 as indicated by a broken line. Yes.

  FIG. 3 shows a case where the display screen 14 of the display 2 is switched to the non-display state. In this case, the entire first surface 8 of the beam splitter 1 functions as a mirror, and the first surface 8 includes an object positioned opposite to the first surface 8 (in this example, a wheelchair user and The car door 10) is starting to open.

  FIG. 4 shows elevator elevator car 4 elevating control, car door 10 opening / closing control, display 2 display state non-display state switching control in an elevator including the elevator display device shown in FIGS. 1 to 3. It is a block diagram which shows the electrical connection structure for performing.

  The elevator is provided with an elevator control unit 16 that performs various controls of the entire elevator including the elevator car 4 elevating control and the car door 10 opening / closing control. The elevator control unit 16 includes a general landing control panel 17a and a wheelchair landing control panel 17b, a hoisting machine 18, and a general elevator provided in the elevator platform 4 of each floor. An in-car operation panel 19a, a wheelchair in-car operation panel 19b, the door motor 11, the display control unit 3 and the like are connected.

  The hall operation panels 17a and 17b are each provided with a car call button, a door open button, a door close button, and the like. The elevator control unit 16 has two modes, a normal mode and a wheelchair mode, as modes for driving the elevator. When the general landing control panel 17a is operated, the elevator is operated in the normal mode, and the elevator control unit 16 When the platform operating panel 17b is operated, the elevator is driven in the wheelchair mode. The wheelchair mode is a mode in which a wheelchair user can use the elevator safely and easily. When driving in the wheelchair mode, the timing of opening the car door 10 is delayed and the time until the car door 10 is closed is longer than when driving in the normal mode. is there.

  The in-car operation panels 19a and 19b are each provided with a destination floor button, a door open button, a door close button, and the like. When the in-car operation panel 19a for general use is operated, the elevator is operated in the normal mode, and when the in-car operation panel 19b for wheelchair is operated, the elevator is operated in the wheelchair mode.

  The hoist 18 is provided with a sheave (not shown) that is rotationally driven, and an elevator rope (not shown) is wound around the sheave. An elevator car 4 is connected to one end side of the elevator rope, and a counterweight (not shown) is connected to the other end side of the elevator rope. The hoisting machine 18 is driven by a drive signal output from the elevator control unit 16, and the sheave rotates by driving the hoisting machine 18, and the elevator car 4 moves up and down by rotating the sheave.

  Control for switching the display screen 14 of the display 2 between the display state and the non-display state in accordance with the operation state of the elevator will be described based on the flowchart shown in FIG. A case will be described in which the elevator operation mode is the wheelchair mode and the display control unit 3 switches the display screen 14 of the display 2 from the display state to the non-display state when the car door 10 is opened.

  First, it is determined whether or not the elevator is started (S1). As for the operation of the elevator, the landing operation panel 17a (or 17b) or the in-car operation panel 19a (or 19b) is operated, and a signal output based on the operation is input to the elevator control unit 16. Is started.

  When the operation of the elevator is started, the display screen 14 of the display 2 is switched to the display state (S2).

  After the operation of the elevator is started and the display screen 14 of the display 2 is switched to the display state, it is determined whether or not the operation mode of the elevator is a wheelchair mode (S3). When the wheelchair landing operation panel 17b or the wheelchair in-car operation panel 19b is operated, the elevator operation mode becomes the wheelchair mode. On the other hand, when the general hall operating panel 17a or the general car operating panel 19a is operated, the operation mode of the elevator is the normal mode. When the wheelchair landing operation panel 17b and the general landing operation panel 17a are operated, the driving mode becomes the wheelchair mode. Similarly, when the wheelchair in-car operation panel 19b and the in-car in-car operation panel 19a are operated, the driving mode becomes the wheelchair mode.

  When the driving mode is the wheelchair mode (YES in S3), it is determined whether or not the car door 10 is being opened (S4). “When the car door 10 is opened” means, for example, when a signal for opening the car door 10 is output from the elevator controller 16 to the door motor 11 or from a sensor (not shown) to the elevator controller 16. This means, for example, a signal that detects that the car door 10 has started to open.

  When the driving mode is wheelchair mode (YES in S3) and the car door 10 is opened (YES in S4), the display screen 14 of the display 2 is switched to the non-display state (S5). When the display screen 14 of the display 2 is switched to the non-display state, the entire first surface 8 of the beam splitter 1 functions as a mirror, as shown in FIG. An object located opposite to the first surface 8 (in this example, a wheelchair user and a car door 10 starting to open) is reflected.

  Thereafter, it is determined whether or not the opened car door 10 is closed (S6). If the car door 10 is closed (YES in S6), the display screen 14 of the display 2 is switched to the display state (S7). ), A series of switching control ends.

  On the other hand, when the operation mode of the elevator is the normal mode (NO in S3), the elevator is operated in the normal mode (S8), and the display screen 14 of the display 2 is maintained in the display state.

  In such a configuration, an image displayed on the display screen 14 of the display 2 passes through the beam splitter 1 and can be viewed from the first surface 8 side of the beam splitter 1 as shown in FIG. For this reason, various information can be provided to the elevator user who gets in the elevator car 4 using the display 2.

  The display 2 is disposed so as to be covered by the beam splitter 1. For this reason, the display 2 is not exposed in the elevator car 4 and is almost invisible to an elevator user who rides in the elevator car 4. For this reason, the elevator car 4 can be maintained in a clean design, and the aesthetic appearance of the elevator car 4 can be improved. Further, the display 2 is fitted into a mounting hole 12 formed in the side plate 7, and the mounting hole 12 is covered with a beam splitter 1 disposed in close contact with the side plate 7. For this reason, the display 2 and the beam splitter 1 do not protrude into the elevator car 4, and an elevator user who gets in the elevator car 4 hits the display 2 and the beam splitter 1 protruding into the elevator car 4. Accidents can be prevented.

  When the display 2 is replaced, it can be replaced with a display 2 of any size regardless of the size of the display 2 currently used. For example, when the size of the display 2 to be replaced is smaller than the display 2 currently used, the new display 2 may be fitted into the mounting hole 12 without changing the size of the mounting hole 12. In this case, a gap is generated between the mounting hole 12 and the outer periphery of the new display 2, but this gap is covered with the beam splitter 1 and is hardly visible to elevator users who ride in the elevator car 4. Even if it is left as it is, the beauty in the elevator car 4 will not be damaged. Further, when the size of the display 2 to be replaced is larger than the display 2 currently used, the attachment hole 12 may be expanded. The machining marks generated when the mounting hole 12 is expanded are hardly visible to the elevator user who is covered by the beam splitter 1 and rides in the elevator car 4. The aesthetics in the car 4 are not impaired. For this reason, when the display 2 is replaced, a display 2 having an arbitrary size can be used, and labor and cost required for replacing the display 2 can be suppressed.

  In the case where the elevator is operated in a wheelchair mode, when the car door 10 of the entrance / exit 6 is opened, the display screen 14 of the display 2 is switched to the non-display state, and the entire surface of the beam splitter 1 functions as a mirror. For this reason, when a wheelchair user goes backward and gets off from the elevator car 4, the beam splitter 1 can be used to check the back, and the wheelchair user can use the elevator safely and easily. .

  In the present embodiment, the case where the display screen 14 of the display 2 is switched to the non-display state has been described as an example of the case where the entire display screen 14 is switched to the non-display state. The part may be switched to the non-display state and the other part may be maintained in the display state. In this case, when the wheelchair user moves backward and gets off, the area necessary for confirming the back is switched to the non-display state, and the other areas are maintained in the display state.

The human sensor 20 is attached to the ceiling board near the entrance 6 in the elevator car 4 and is connected to the display control unit 3A. The human sensor 20 detects when an elevator user who gets in the elevator car 4 approaches the entrance / exit 6 from a set distance. Note that the human sensor 20 may be of a type in which the detection output changes depending on the distance from the human sensor 20. In this case, when the detection output becomes larger than the set threshold value, it is determined that the elevator user in the elevator car 4 is closer to the entrance / exit 6 than the set distance.

  The display control unit 3A displays the display when the human operation sensor 20 detects that the elevator operation mode is the wheelchair mode and the elevator user in the elevator car 4 is closer to the entrance / exit 6 than the set distance. The whole or part of the display screen 2 is switched to the non-display state.

  In such a configuration, when a wheelchair user gets in the elevator car 4, the wheelchair user who has boarded the vehicle is generally up to a position far from the entrance / exit 6 (position approaching the beam splitter 1). When traveling and getting off, it moves away from the beam splitter 1 and approaches the entrance / exit 6.

  Therefore, the human sensor 20 detects that an elevator user (for example, a wheelchair user) who has been driven in the wheelchair mode and is in the elevator car 4 has approached the entrance / exit 6 from the set distance, and this detection When the signal is transmitted to the display control unit 3A, the display control unit 3A switches all or a part of the display screen 14 of the display 2 to the non-display state so that the beam splitter 1 can be used as a mirror. Thereby, when a wheelchair user moves backward and gets off from the elevator car 4, the back can be confirmed using the beam splitter 1, and the wheelchair user can use the elevator safely and easily. .

The receiving unit 22 is connected to the display control unit 3B. The receiving unit 22 can be installed in any place in the elevator car 4, for example, near the ceiling board. The wireless IC tag 21 transmits personal identification information of an elevator user who carries each wireless IC tag 21, and outputs, for example, personal identification information that identifies a wheelchair user.

  The display control unit 3B displays the display when the operation mode of the elevator is the wheelchair mode and the signal from the wireless IC tag 21 received by the receiving unit 22 identifies the wheelchair user. The whole or part of the screen 14 is switched to the non-display state.

  In such a configuration, when the elevator is operated in the wheelchair mode and the receiving unit 22 receives the personal identification information from the wireless IC tag 21 carried by the wheelchair user, the display control unit 3B displays the display screen 14 of the display 2. Are switched to the non-display state so that the beam splitter 1 can be used as a mirror. Thereby, when a wheelchair user moves backward and gets off from the elevator car 4, the back can be confirmed using the beam splitter 1, and the wheelchair user can use the elevator safely and easily. .

  When this wireless IC tag 21 is used, the type of information desired by each elevator user is included in the personal identification information transmitted from the wireless IC tag 21, and the display 2 is displayed for each elevator user. You can also change the information displayed.
