The detection section 15 has a function of detecting the approach of the detection object 21 to the landing door 11. Here, the test object 21 includes a part of the body of the user, clothing, and a carrying article. The detection section 15 is a section that detects an operation of the call registration button 17 by a user. Here, the user operates the hall door 11 by bringing the indicator into proximity with a portion of the projected image where the call registration button 17 to be operated is displayed. Here, the instruction body is a detection object 21 that instructs the call registration button 17 as the operation target. The indicator is, for example, a hand, palm or finger of the user, or a stick or umbrella held by the user. The detection unit 15 includes, for example, a distance sensor 22.
The distance sensor 22 is a device that measures the distance to the detection object 21 in a non-contact manner.

The oscillating portion 22a is a portion that emits ultrasonic waves along the front surface of the landing door 11. The vibration receiving unit 22b is a unit for measuring a reflected wave of the ultrasonic wave emitted from the oscillating unit 22a and reflected by the object 21. The distance sensor 22 measures the distance to the object 21 based on, for example, the flight time from the emission of the ultrasonic wave from the oscillator 22a to the arrival of the reflected wave at the oscillator 22 b. The detection section 15 determines the approach of the detection object 21 to the landing door 11 based on the distance measured by the distance sensor 22.
The transmission section 16 is connected to the communication section 7 of the control device 4 so as to be able to transmit a signal for registering a call corresponding to the call registration button 17 whose operation is detected by the detection section 15.
Fig. 3 is a view showing a landing 8 provided with the landing operating panel device 12 according to embodiment 1.
The landing operating panel device 12 is provided above the corresponding landing door 11 at the landing 8. The landing operating panel device 12 is provided, for example, above the triple box 10. In this case, the projection section 14 is provided above the landing door 11. The detection section 15 is provided above the landing door 11. The distance sensor 22 of the detection section 15 is provided above a portion of the landing door 11 where the image of the call registration button 17 is projected by the projection section 14, for example.
Preferably, in the landing 8 shown in this example, landing equipment of the elevator 1 is not provided on a wall surface on the side and in front of the landing door 11. Here, the landing equipment includes, for example, a landing operation panel formed of hardware buttons such as buttons and touch buttons, an indicator, and a hall lantern.
Next, the function of the station operating panel device 12 will be described with reference to fig. 4 to 10.
Fig. 4, 5, and 7 to 10 are views showing a landing according to embodiment 1. Fig. 6 is a configuration diagram of an elevator according to embodiment 1.
Fig. 4 shows the landing 8 with the landing door 11 closed.
In this example, the user uses the elevator 1 to move from the 2 floors of the building to the upper floors. The user operates the landing door 11 corresponding to the car C.
The control device 4 transmits a signal indicating a projected image, which is an image of the operating panel, to the receiving section 13 of the landing operating panel device 12 corresponding to the closed landing door 11. The projection unit 14 projects a projection image represented by the signal transmitted to the reception unit 13 onto the front surface of the landing door 11. The projection unit 14 projects the projection image onto the XY plane in fig. 4. In this example, the projection range of the projection unit 14 does not include the wall surface of the landing 8. The projected image includes a guidance display for introducing an operation method to a user. The guidance display includes guidance of a non-contact operation method, such as "please reach", for example.
As shown in fig. 5, the user operates, for example, to extend his or her hand to the call registration button 17 in accordance with the guidance display. In this case, the guidance display may be changed to a display for guiding the user to maintain the non-contact state, such as "please keep the hands extended". The user stops the hand reaching the call registration button 17, for example, in accordance with the guidance display.
The detection unit 15 detects the operation of the user as follows, for example.
The distance sensor 22 measures, for example, the distance to the ground when the user is not operating the device. When the user performs an operation by reaching out, for example, the distance sensor 22 measures the distance from the user's hand. The detection section 15 detects the approach of a hand as the detection object 21 to the landing door 11 based on the change in the distance value measured by the distance sensor 22. The detection unit 15 detects the approach of the detection object 21 when, for example, the distance value measured by the distance sensor 22 is within a predetermined range.
Then, the detection section 15 determines whether or not the detection object 21 whose approach has been detected is stationary before the call registration button 17, based on whether or not the distance value after the change is within the range set in advance for the call registration button 17. In this example, the up call registration button 19 and the down call registration button 20 are arranged vertically. The distance sensor 22 is provided above the portion of the hall door 11 where the images of the up call registration button 19 and the down call registration button 20 are projected. The detection section 15 determines whether or not the detection object 2 is stationary before any call registration button 17 of the up call registration button 19 or the down call registration button 20, based on the distance value of the distance sensor 22. The detection unit 15 detects the operation of the call registration button 17 that is approaching the detection object 21 when the detection object 21 is stationary longer than a preset detection time.
The transmission section 16 transmits a signal for causing the hall call registration corresponding to the call registration button 17 whose operation is detected by the detection section 15 to the communication section 7 of the control device 4.
The group control unit 5 registers a hall call based on the signal received by the communication unit 7. The group control unit 5 selects a car 3 to which a registered hall call is assigned from among the plurality of cars 3.
As shown in fig. 6, when the car B arrives at the floor 2 first, the group control unit 5 selects, for example, the car B as the car 3 to which the registered hall call is assigned. At this time, the control device 4 transmits a signal indicating an image for guiding the car 3 to which the hall call is assigned to the receiving section 13.
As shown in fig. 7, the projection unit 14 projects an image for guiding the car 3 to which a hall call is assigned, onto the front surface of the hall door 11. The projection unit 14 of the landing operating panel device 12 corresponding to the car C operated by the user projects a display for guiding the car 3 to which a landing call is assigned, such as "please board the car B", on the front surface of the landing door 11. The projection unit 14 of the hall operating panel device 12 corresponding to the car B to which the hall call is assigned projects a display for guiding waiting, such as "please wait for arrival" or the like, onto the front surface of the hall door 11.
The user looks at the display projected onto the front surface of the landing door 11 and waits before the car B to which the landing call is assigned. The user rides the car 3 that has reached the 2 th floor and moves to the upper floor.
Fig. 8 shows the landing 8 during the closing operation of the landing door 11.
During the closing operation of the landing door 11, the control device 4 transmits a signal indicating a projected image for calling attention to the receiving unit 13 instead of the projected image of the operation panel. The closing operation of the landing door 11 is performed, for example, from a state in which the landing door 11 is fully opened to a state in which the landing door is fully closed.
The projection unit 14 projects the projection image represented by the signal transmitted to the reception unit 13 onto the ground. The projection unit 14 projects the projected image onto the floor of the landing 8. The projection unit 14 projects the projected image onto the floor of the car 3 through the landing doorway 9. The projection unit 14 may project the projected image onto the front surface of the landing door 11 that is closing. At this time, the image of the operation panel is not displayed. In the projection image, a guidance for calling attention, such as "please pay attention to close the door", is displayed. In the projection image, guidance in the operation direction of the car 3, such as "going upward", may be displayed together.
As shown in fig. 9, when the detection object 21 approaches the landing door 11 during the closing operation of the landing door 11, the detection section 15 detects the approach of the detection object 21. The detection unit 15 detects the approach immediately when, for example, the value of the distance measured by the distance sensor 22 changes. At this time, the transmission section 16 transmits a signal for opening the landing door 11 to each of the station control sections 6 via the communication section 7. Here, the signal for opening the landing door 11 is, for example, a signal for opening a car door of the car 3 corresponding to each control section 6.
The car door that has been closed by the landing door 11, which has detected the approach of the detection object 21, follows the car door, and is reversed from the closing operation by the control signal from each control unit 6, and is opened. The landing door 11 follows the car door to open.
At this time, the control device 4 transmits a signal indicating a projected image to call attention to the receiving unit 13. The projection unit 14 projects a projection image onto the ground or the like. In the projected image, for example, "please do not sandwich the article" is displayed. The door is about to close. "etc. evoke the attention.
Thereafter, when the object 21 does not approach the landing door 11, the landing door 11 follows the car door to perform a closing operation. After the landing doors 11 are fully closed, the control device 4 transmits a signal indicating a projected image of the operation panel to the receiving section 13.
Fig. 9 shows the landing 8 during the opening operation of the landing door 11.
During the opening operation of the landing door 11, the control device 4 transmits a signal indicating a projected image calling attention to the receiving unit 13 instead of transmitting the projected image of the operation panel. The time during which the landing door 11 is opened is, for example, from a state in which the landing door 11 is fully closed to a state in which the landing door is fully opened. The control device 4 may transmit a signal indicating a projected image for calling attention to the receiving unit 13 from before the landing door 11 starts the opening operation.
The projection unit 14 projects the projection image represented by the signal transmitted to the reception unit 13 onto the ground. The projection unit 14 projects a projection image onto the floor of the landing 8. The projection section 14 projects a projection image onto the floor of the car 3 through the landing doorway 9. The projection unit 14 may project a projection image onto the front surface of the landing door 11 to be opened. At this time, the image of the operation panel is not displayed. In the projected image, a guidance for calling attention, such as "please pay attention to open the door", is displayed. The projection image may also display guidance in the operation direction of the car 3, such as "upward travel", for example.
Next, an example of the operation of the docking operating panel device 12 will be described with reference to fig. 11 and 12.

In step S16, the receiving unit 13 receives a signal indicating an image for guiding the car 3 to which the registered hall call is assigned from the control device 4. Thereafter, the operation of the landing operating panel device 12 proceeds to step S17.
In step S17, the projection unit 14 projects an image for guiding the car 3 to which a hall call is assigned, onto the front surface of the hall door 11. After that, the operation of the hall operating panel device 12 relating to the call registration is ended.
Fig. 12 shows an example of the operation of closing the landing door 11.
In step S21, the landing operating panel device 12 determines whether or not the closing operation of the landing door 11 is completed. If the determination result is "no," the operation of the landing operating panel device 12 proceeds to step S22. If the determination result is yes, the operation of the landing operating panel device 12 during the closing operation of the landing door 11 is ended.
In step S22, the receiving unit 13 receives a signal indicating a video to call attention from the control device 4. Thereafter, the operation of the landing operating panel device 12 proceeds to step S23.
In step S23, the projector 14 projects a video for guiding attention on the ground instead of the video of the operation panel. Thereafter, the operation of the landing operating panel device 12 proceeds to step S24.
In step S24, the detection unit 15 determines whether or not the detection object 21 is approaching the landing door 11. If the determination result is "no," the operation of the landing operating panel device 12 proceeds to step S21. If the determination result is yes, the operation of the landing operating panel device 12 proceeds to step S25.
In step S25, the transmission unit 16 transmits a signal for opening the landing door 11 to the control device 4. Thereafter, the operation of the landing operating panel device 12 proceeds to step S26.
In step S26, the receiving unit 13 receives a signal indicating a video to call attention from the control device 4. Thereafter, the operation of the landing operating panel device 12 proceeds to step S27.
In step S27, the projection unit 14 projects an image for guiding the image for calling attention onto the floor. After that, the operation of the hall operating panel device 12 relating to the call registration is ended.
Next, another example of embodiment 1 will be described with reference to fig. 13.
Fig. 13 is a configuration diagram of an elevator according to a modification of embodiment 1.
In the elevator 1 of this example, the hoistway 2 is provided outside the wall surface of the building. That is, at least one of the four side surfaces of the hoistway 2 is exposed to the inside or outside of the building. The hoistway 2 is formed as an internal space of a structure standing upright, for example, in a vertical direction. At least any one of the side surfaces of the hoistway 2 may be formed of a material having permeability, such as glass. The hoistway 2 may be a glass hoistway.
No wall surface is provided at the landing 8 in this example.
The control device 4 includes, for example, a plurality of hardware corresponding to each of the group control unit 5, the plurality of individual control units 6, and the communication unit 7.
As described above, the landing operating panel device 12 according to embodiment 1 includes the projection unit 14, the detection unit 15, and the transmission unit 16. The projection section 14 is provided in the landing 8 of the elevator 1. The projection unit 14 projects an image onto the front surface of the landing door 11. The detection section 15 is provided in the landing 8. The detection section 15 detects the non-contact approach of the detection object 21 to the landing door 11. The detection section 15 detects an operation to the call registration button 17 when the detection object 21 approaches the portion of the landing door 11 on which the call registration button 17 is displayed in the image. The transmission section 16 transmits a signal to a registration section that registers a call of the elevator 1, the signal causing the registration section to register a call corresponding to the call registration button 17 that the detection section 15 detected the operation.
The image is projected to the front of the landing door 11. The landing operating panel device 12 receives a user's operation of an image displayed on the front surface of the landing door 11. This eliminates the need to separately provide a hall device such as a hall operating panel, an indicator, and a hall lamp formed of a hardware button at the hall 8. Thus, the area of the landing 8 is not occupied by these landing devices. In addition, the area of the wall surface on the side of the landing doorway 9 is not occupied by these landing devices. This does not limit the degree of freedom in designing the landing 8 and the degree of freedom in the use of the landing 8. The wall surface of the hall 8 is used for displaying, for example, advertisements, guidance, and the like by a notice, a sign, and the like. Thus, the hall operating panel device 12 does not require a separate device for displaying the operating panel of the elevator 1, and can perform call registration regardless of the presence or absence of the wall surface of the hall 8. Further, even when the landing 8 has a wall surface, the usage of the landing 8 is not limited.
In a hardware button such as a button or a touch button, fatigue, abrasion, damage, and the like of a movable portion may occur due to repeated operation. In addition, the hardware button may be broken or damaged due to the mixing of foreign substances or the like. Here, the landing operating panel device 12 does not require a user to operate with a hardware button. The landing operating panel device 12 detects a non-contact operation by a user. Therefore, physical failure of the call registration button 17 that accepts user operation can be avoided.
Since the landing equipment does not occupy the wall surface area of the landing 8, the interval between the plurality of cars 3 can be reduced in the elevator 1 having the plurality of cars 3. This can reduce the area occupied by the elevator in the building.
The projection section 14 is provided above the landing door 11.
The projection unit 14 projects a projection image from above the user. Therefore, the projected image is not easily blocked by the user.
The detection section 15 is provided above the landing door 11.
The detection unit 15 detects the detection object 21 from above the user. Therefore, the detection of the operation of the call registration button 17 by the user by the detection section 15 is not easily blocked by other users. In particular, when the projection section 14 and the detection section 15 are provided above the landing door 11, the landing operating panel device 12 can be easily installed in an existing elevator by integrally molding the projection section 14 and the detection section 15.
The projection unit 14 projects an image onto the floor when the landing door 11 is opened.
The projection unit 14 can display images to users regardless of the open/close state of the landing doors 11. The projection unit 14 projects an image on the landing door 11 provided at the landing doorway 9 or on the floor in front of and behind the landing doorway 9. Therefore, even when the elevator 1 includes a plurality of cars 3, the user can clearly grasp from which landing doorway 9 the user can get on the elevator.
When the detection section 15 detects the approach of the detection object 21 during the closing operation of the landing door 11, the transmission section 16 transmits a signal for causing the landing door 11 to open to a door control section that controls the opening and closing of the landing door 11.
The detection section 15 also serves as a sensor for detecting the object 21 that may be caught during the closing operation of the landing door 11. Therefore, instead of a dedicated sensor for detecting the object 21, the landing operating panel device 12 may be provided. Therefore, the landing operating panel device 12 can be introduced without increasing the number of devices in the elevator 1.
The projection unit 14 projects an image for calling attention instead of the image for displaying the call registration button 17 when the landing door 11 is opened or closed.
When the detection object 21 comes into contact with the landing door 11 during the opening and closing operation of the landing door 11, the landing door 11 may be an obstacle to the opening and closing operation. Therefore, it is preferable that the detection object 21 does not approach during the opening and closing operation of the landing door 11. Since the user is alerted so that the detection object 21 does not approach, the contact of the detection object 21 can be prevented. Since the image for calling attention is performed instead of the image of the call registration button 17, it is possible to prevent the user from touching the detection object 21 with the landing door 11 in an attempt to operate the call registration button 17 when the landing door 11 is opened or closed.
The detection unit 15 is provided with a distance sensor 22. The distance sensor 22 measures the distance to the detection object 21 in a non-contact manner. The detection unit 15 detects the approach of the detection object 21 based on the distance measured by the distance sensor 22.
The detection section 15 can accurately determine the position of the detection object 21 that the user approaches the landing door 11 for operation by using the distance sensor 22. Thus, the detection section 15 can specify the call registration button 17 to be operated by the user with high accuracy by a non-contact method. The detection unit 15 may include a plurality of distance sensors 22. The plurality of distance sensors 22 may be of different kinds from each other.
Further, the distance sensor 22 emits ultrasonic waves along the front face of the landing door 11. The distance sensor 22 measures the distance to the object 21 by measuring the reflected wave of the ultrasonic wave.
Since the distance sensor 22 measures the distance using ultrasonic waves, it is less susceptible to the image projected by the projection unit 14. The distance sensor 22 is less likely to be affected by the color of the clothing of the user. Further, the distance sensor 22 is not interfered with by disturbance light such as sunlight. Therefore, even when there is a wall surface in the hall 8, the hall operating panel device 12 can perform call registration regardless of the transparency of the wall surface to visible light. The landing operating panel device 12 can be applied to any elevator 1 installed outdoors, semi-outdoors, or indoors. The landing operating panel device 12 can also be applied to a case where a glass window W is provided on a wall surface of the landing 8, and a case where the wall surface of the landing 8 is a permeable resin wall, for example. The landing operating panel device 12 can also be applied to an elevator 1 in a glass hoistway.
The signal representing the projected image may be, for example, image data itself. Alternatively, the signal may be display information for generating a projection image. The signal may be, for example, a signal indicating a code for specifying an image stored in the hall operating panel device 12.
Next, an example of the hardware configuration of the docking station operating panel device 12 will be described with reference to fig. 14.
Fig. 14 is a diagram showing a hardware configuration of a main part of a hall operating panel device according to embodiment 1.
Each function of the landing operating panel device 12 can be realized by a processing circuit. The processing circuit is provided with at least one processor 12b and at least one memory 12 c. The processing circuit may include a processor 12b and a memory 12c, or may include at least one dedicated hardware 12a instead of or in addition to them.
When the processing circuit includes the processor 12b and the memory 12c, each function of the hall operating panel apparatus 12 is realized by software, firmware, or a combination of software and firmware. At least one of the software and the firmware is described as a program. The program is stored in the memory 12 c. The processor 12b reads out and executes a program stored in the memory 12c, thereby realizing each function of the hall operating panel apparatus 12.
The processor 12b is also called a CPU (Central Processing Unit), a Processing device, an arithmetic device, a microprocessor, a microcomputer, or a DSP. The memory 12c is constituted by a nonvolatile or volatile semiconductor memory such as a RAM (random access memory), a ROM (read only memory), a flash memory, an EPROM (erasable programmable read only memory), and an EEPROM (electrically erasable programmable read only memory), a magnetic Disk, a flexible Disk, an optical Disk, a CD (compact Disk), a mini Disk (minidisc), and a DVD (Digital Versatile Disk).
When the processing circuit includes the dedicated hardware 12a, the processing circuit is realized by, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (application specific integrated circuit), an FPGA (field programmable gate array), or a combination thereof.
Each function of the landing operating panel device 12 can be realized by a processing circuit. Alternatively, the functions of the landing operating panel device 12 may be realized by a processing circuit in a centralized manner. The functions of the hall operating panel device 12 may be partially implemented by dedicated hardware 12a, and the other parts may be implemented by software or firmware. In this way, the processing circuit realizes each function of the hall operating panel device 12 by hardware 12a, software, firmware, or a combination thereof.
In embodiment 2, points different from the example disclosed in embodiment 1 will be described in detail. As for the features not described in embodiment 2, any features of the example disclosed in embodiment 1 may be adopted.
Fig. 15 and 16 are views showing a landing according to embodiment 2.
Fig. 15 shows the landing 8 with the landing door 11 closed.
In this example, the plurality of call registration buttons 17 correspond to, for example, a hall call in which a destination floor is specified. The call registration button 17 displays, for example, only the number of the destination floor. The call registration button 17 may be a button for specifying a destination floor using a numeric keypad, for example.
The distance sensor 22 of the detection unit 15 includes, for example, a light emitting unit 22c and a light receiving unit 22 d. The light emitting portion 22c is a portion that emits light along the front surface of the landing door 11. The light emitted from the light emitting unit 22c is, for example, laser light. The light emitted from the light emitting unit 22c is, for example, invisible light. The light emitted from the light emitting unit 22c is, for example, infrared light. The light receiving unit 22d is a part for measuring the reflected light of the light emitted by the light emitting unit 22c reflected by the detection object 21. The distance sensor 22 measures the distance to the object 21 based on, for example, a phase difference between the light emitted from the light emitting unit 22c and the reflected light measured by the light receiving unit 22 d. Alternatively, the distance sensor 22 may measure the distance to the object 21 based on, for example, the distance from the point where the light emitting unit 22c emits light to the point where the light receiving unit 22d measures the reflected light. The detection section 15 determines the approach of the detection object 21 to the landing door 11 based on the distance measured by the distance sensor 22.
In this example, the detection unit 15 has a function of scanning the direction in which the distance sensor 22 measures the distance. The Detection unit 15 is, for example, a scanning LIDAR (Light Detection and Ranging). The detection unit 15 determines the position and shape of the detection object 21 in the three-dimensional space by scanning with the distance sensor 22.
As shown in fig. 16, the user operates the handle to extend to the call registration button 17.
When the user operates the hand, for example, by stretching the hand, the detection unit 15 specifies the position and shape of the hand of the user. The detection section 15 detects the approach of a hand as the detection object 21 to the landing door 11 based on a change in the value of the distance measured by the distance sensor 22. For example, when the size of the approaching detection object 21 is larger than a predetermined size, the detection unit 15 determines the detection object 21 as the indicator. The size of the detection object 21 is, for example, a projection area of the detection object 21 onto the ground. Alternatively, the detection unit 15 may determine the detection object 21 as the indicator regardless of the size of the detection object 21.
Then, the detection section 15 determines whether or not the instruction body detected to be in proximity is stationary before the call registration button 17, based on whether or not the position of the instruction body is within a range set in advance for the call registration button 17. The detection unit 15 detects an operation of the call registration button 17 that the instruction body approaches when the instruction body is stationary longer than a preset detection time.
The transmission section 16 transmits a signal for registering a hall call corresponding to the call registration button 17 whose operation is detected by the detection section 15 to the communication section 7 of the control device 4.
As described above, the distance sensor 22 of the landing operating panel device 12 according to embodiment 2 emits light along the front surface of the landing door 11. The distance sensor 22 measures the distance to the detection object 21 by measuring the reflected light of the light.
Since the distance sensor 22 measures the distance by using light, the approach of the detection object 21 can be detected at a high response speed. Further, since the propagation speed of light is independent of the temperature of air, the distance sensor 22 can stably measure the distance regardless of the air temperature of the landing 8. In particular, when the distance sensor 22 measures the distance using invisible light, the distance sensor 22 does not give a user a sense of discomfort due to the emitted light.
In addition, when a device that controls opening and closing of the car door is provided in the upper part of the car 3, for example, the transmission unit 16 may directly transmit a control signal that causes the landing door 11 to follow opening by opening the car door to the device. In this case, this device is an example of a door control unit.
In embodiment 3, differences from the examples disclosed in embodiment 1 and embodiment 2 will be described in detail. As for the features not described in embodiment 3, any of the features disclosed in the examples of embodiment 1 or embodiment 2 may be adopted.
Fig. 17 is a diagram showing a landing according to embodiment 3.
In this example, the elevator 1 includes a single car 3. The control device 4 is, for example, a control panel, not shown, of the elevator 1. The registration unit and the door control unit are provided in, for example, a control panel of the elevator 1.
A landing doorway 9 is provided over the entire front surface of the landing 8. That is, a wall surface parallel to the landing doorway 9 is not provided on the front surface of the landing 8. The landing operating panel device 12 does not require a wall surface on the front surface of the landing 8. In this way, the landing operating panel device 12 can improve the degree of freedom in designing the landing 8.
The detector 15 includes, for example, a light emitter 15a and a light receiver 15 b. The light projector 15a is provided on one of the left and right sides of the three frames 10, for example. The light receiving unit 15b is provided on the other of the left and right sides of the triple box 10, for example. The light receiving unit 15b faces the light projecting unit 15a on the front side of the landing door 11.
The light projector 15a is a part that emits light toward the light receiver 15b so as to extend along the front surface of the landing door 11. The light emitted from the light projector 15a is, for example, infrared light. The light emitted from the light projecting section 15a includes a plurality of light beams, for example. The light receiving unit 15b is a unit for measuring light emitted from the light projecting unit 15 a. For example, when the light emitted from the light emitter 15a is blocked by the detection object 21 and the light is not detected by the light receiver 15b, the detection unit 15 determines that the detection object 21 is close to the landing door 11. The detection unit 15 identifies the call registration button 17 operated by the user, for example, by identifying the light beam blocked by the detection object 21 among the plurality of light beams included in the light emitted from the light projecting unit 15 a. This enables the detection unit 15 to be realized with a simple configuration.
