The inspection switch 1 is provided in the control panel and is connected to a power supply circuit (not shown). When the inspection switch 1 is turned on, an on signal is output to the buzzer 2 as a notification means. A call signal from the landing call button 3 is also output to the buzzer 2. The buzzer 2 emits a buzzer sound when signals from both the inspection switch 1 and the landing call button 3 are input. The call signal output from the landing call button 3 is output to the call input device 4 as indicated by a dotted arrow during normal driving. The call input device 4 is adapted to register a call to an elevator control device (not shown) based on the input of the hall call signal.

Next, the operation of FIG. 1 will be described. When a maintenance person wants to inspect the elevator machine,
The maintenance staff opens the door of the control panel of the elevator and turns on the inspection switch 1. Thereby, the maintenance staff can start the inspection work. That is, in this state, when the elevator user tries to use the elevator under inspection work and presses the landing call button 3 at the landing on a certain floor, the buzzer 2 emits a buzzer sound. This buzzer sound allows the elevator user to auditorily recognize that the elevator is not in a normal operating state, and will try to use another elevator or use the stairs to reach the target floor. Try to go to.

FIG. 2 is a block diagram showing the configuration of the second embodiment of the present invention. In the configuration of FIG. 2, an audio output device 5 having a speaker or the like is used instead of the buzzer 2 of FIG. Then, when the elevator user presses the landing call button 3 while the inspection switch 1 is in the ON state, the voice output device 5 utters a predetermined message such as, "For example, this elevator is currently in the process of being inspected." The audible notification using such a message enables the elevator user to clearly recognize that the elevator No. which he / she is about to ride is currently undergoing inspection work.

FIG. 3 is a block diagram showing the configuration of the third embodiment of the present invention. This embodiment is a combination of the first embodiment and the second embodiment. As shown in the figure, the buzzer 2 of the first embodiment and the audio output device 5 of the second embodiment are arranged in parallel. It is connected to the. According to the third embodiment, the elevator user can immediately recognize that the state is different from that during normal operation by the buzzer sound of the buzzer 2, and the message contents uttered by the voice output device 5 can It can be clearly recognized that the different states are currently in the elevator inspection work.

FIG. 4 is a block diagram showing the configuration of the fourth embodiment of the present invention. As in the first to third embodiments described above, the inspection switch 1 is provided in the control panel and is connected to a power supply circuit (not shown). When the inspection switch 1 is turned on, an on signal is output to the elevator position indicator 6. On the other hand, when the hall call button 3 is pressed, the call signal is output to the call input device 4 as indicated by the dotted arrow, but during the inspection work, the display control means 7 is indicated as indicated by the solid arrow. It is designed to be output to.
When the signal from the hall call button 3 is input, the display control means 7 blinks the elevator position indicator 6 and the hall call button 3.

The elevator position indicator 6 is provided in the vicinity of the landing call button 3. For example, 7 × 11 display elements called "dot matrix" indicate the floor on which the elevator is currently located. It is also possible to display with, or to display other simple messages or symbols. This elevator position indicator 6
During normal operation, the floor of the current position of the elevator car is displayed as a number by a control signal from the elevator controller 8 as indicated by a dotted arrow.

Next, the operation of FIG. 4 will be described. When a maintenance person wants to inspect the elevator machine,
The maintenance staff opens the door of the control panel of the elevator and turns on the inspection switch 1. Thereby, the maintenance staff can start the inspection work. That is, in this state, when the elevator user tries to use the elevator under inspection and presses the landing call button 3 at a landing on a certain floor, the display control means 7 inputs a signal from the landing call button 3. Based on this, the landing call button 3 is caused to blink. As a result, the elevator user can visually recognize that the state is different from that during normal driving. The display control means 7 also
The elevator position indicator 6 is also made to perform a blinking operation, which also allows the elevator user to visually recognize that the state is different from that during normal operation. In this embodiment, the display control means 7 causes both the landing call button 3 and the elevator position indicator 6 to perform the blinking operation, but it is sufficient that only one of them performs the blinking operation. It is possible to achieve the purpose.

Further, the display control means 7 may cause the elevator position indicator 6 to perform a lighting operation in a mode different from that during normal operation, instead of causing the elevator position indicator 6 to blink. For example, all the display elements of the dot matrix forming the elevator position indicator 6 may be turned on, or a predetermined simple symbol indicating that the inspection work is in progress may be displayed. Alternatively, a larger number of display elements than 7 × 11 display elements may be used to display characters such as “during inspection” and “during inspection”. Thus, according to this fourth embodiment,
The elevator user confirms that the elevator is not in normal operation by the blinking operation of at least one of the hall call button 3 and the elevator position indicator 6 when the hall call button 3 is pressed or the lighting operation in a special mode. Can be visually recognized.

In the fourth embodiment, the elevator user visually recognizes from the display functions of the elevator position indicator 6 and the landing call button 3 that the elevator machine he is about to board is in the process of being inspected. However, in addition to this, it is also possible to adopt a configuration that can be recognized auditorily. That is, by combining the configuration of FIG. 4 with any one of the configurations of FIG. 1 to FIG.
When is pressed, the elevator position indicator 6 and the landing call button 3 blink and the like, and the buzzer 2 or the voice output device 5 indicates that the inspection work is being performed by the buzzer sound or the utterance of a predetermined message. It may be configured to notify the user.

Further, it is assumed that the inspection switch 1 in each of the above-mentioned embodiments is of a type which is arranged at a predetermined position in the control panel and is switched on and off by a maintenance person by a manual operation. When the switch 1 is installed near the door of the control panel and a maintenance person opens the door of the control panel to perform the inspection work, a switch that is automatically turned on with the opening may be adopted. It is possible. In each of the above-described embodiments, when the maintenance staff forgets to switch the inspection switch 1 to the ON state, the elevator user may recognize that the inspection work is being performed even if the elevator call button 3 is pressed. Although it will not be possible, it will be possible to perform a reliable inspection regardless of whether the maintenance personnel intentionally operated or not by adopting a configuration in which the maintenance personnel automatically turn on when the control panel door is opened in this way. It is possible to inform or display that the work is in progress.
