[0027] 3. Functional Configuration of the Elevator System of the Embodiment FIG. 4 is a diagram showing an example of the functional configuration of the elevator system according to the embodiment. The elevator system 100 includes, as main components related to the control function, a control device 30, a control panel 40, and a light source device 14 including an upward light source unit 14a and a downward light source unit 14b.

[0028] The control panel 40 is a processing device for comprehensively controlling the operation of the car of elevator 1. The control panel 40 is configured to be capable of data communication with the control device 30 via a communication network such as a wired or Internet network. The control panel 40 transmits an operation signal including the moving direction and car position of the car of elevator 1 to the control device 30.

[0029] The control device 30 has the function of a processing device as a computer, and controls the lighting states of the upward light source unit 14a and the downward light source unit 14b according to the moving direction of elevator 1. It has the function of a processing device as a computer. Typically, the control device 30 includes at least one processor 32 and at least one memory 34 coupled to the processor 32. The memory 34 stores at least one program 341 executable by the processor 32 and various data 342 related thereto. By the processor 32 executing the program 341, various processes by the processor 32 are realized.

[0030] FIG. 5 is a functional block diagram showing the functions realized by the processor 32 of the control device 30 executing the program 341. As shown in FIG. 5, the processor 32 includes a signal acquisition unit 321 and a light emission processing unit 322.

[0031] The signal acquisition unit 321 is a functional block for acquiring the operation signal transmitted from the control panel 40. This process is hereinafter referred to as "signal acquisition process". The signal acquisition unit 321 acquires the operation signal at any time.

[0032] The light emission processing unit 322 generates an operation command for causing the light source device 14 to emit light based on the operation signal acquired by the signal acquisition unit 321, and causes the light source device 14 to emit light according to the generated operation command. This processing is hereinafter referred to as "light emission processing".

[0033] In the light emission processing, when the moving direction of the car of the elevator 1 included in the operation signal is the upward direction, the light emission processing unit 322 causes the upper side light source unit 14a to emit light, and when the moving direction is the downward direction, the light emission processing unit 322 causes the lower side light source unit 14b to emit light.

[0034] 4. Specific processing executed in the elevator system of the embodiment Hereinafter, with reference to the flowchart, the operation of displaying the moving direction of the car on the hall lantern 10 as the operation status of the elevator 1 will be described. FIG. 6 is a flowchart of a routine executed by the control device 30. The routine shown in FIG. 6 is repeatedly executed at a predetermined cycle in the processor 32 of the control device 30.

[0035] The process of step S100 corresponds to the signal acquisition process executed in the signal acquisition unit 321. Specifically, in step S100, it is determined whether an operation signal of the elevator 1 has been received from the control panel 40. As a result, if the determination is affirmed, the process proceeds to step S102, and if the determination is not affirmed, the process of this routine ends.

[0036] The processes from step S102 to step S108 correspond to the light emission process executed in the light emission processing unit 322. Specifically, in step S102, it is determined whether the moving direction of the car included in the operation signal is the upward direction. As a result, if the determination is affirmed, the process proceeds to step S104, and if the determination is not affirmed, the process proceeds to step S106.

[0037] In step S104, the upward light source unit 14a emits light. As a result, the upward display 22 is visibly displayed from the first side surface 12a, the second side surface 12b, and the tip surface 12c of the light guide 12. In step S106, it is determined whether the moving direction of the basket included in the operation signal is the downward direction. As a result, if the determination is affirmed, the process proceeds to step S108, and if the determination is not affirmed, the process of this routine is terminated. In step S108, the downward light source unit 14b emits light. As a result, the downward display 24 is visibly displayed from the first side surface 12a, the second side surface 12b, and the tip surface 12c of the light guide 12.

[0038] According to the light emission operation of the hall lantern 10 as described above, an image corresponding to the moving direction of the elevator 1 can be displayed on the light guide 12. Further, when the upward display 22 and the downward display 24 are viewed from the tip surface 12c, they are recognized as displays indicating the moving direction of the basket of the elevator 1. Thereby, even a user waiting for boarding in front of the hall lantern 10 can view the upward display 22 and the downward display 24 displayed through the tip surface 12c of the hall lantern 10.

[0039] 5. Modification The hall lantern 10 of the embodiment may adopt the following modified modes.
