Hereinafter, one embodiment of a passenger conveyor will be described with reference to FIGS. 1 to 6. Note that the following embodiments are exemplified to help understand the configuration of the passenger conveyor, and are not intended to limit the configuration of the passenger conveyor.

As shown in FIG. 1, the passenger conveyor 1 includes, for example, a structure 2 installed on a frame, a transport section 3 for transporting people (passengers), and a transport section 3 arranged so as to sandwich the transport section 3 in a first direction D1. A pair of handrail sections 4 (only one is shown in FIG. 1), a drive section 5 that drives the conveyance section 3 and the handrail section 4, and a processing section 6 that controls the entire device. Good too.

In each figure, the first direction D1 is a first horizontal direction (also referred to as "width direction") D1 which is a direction parallel to the horizontal direction, and the second direction D2 is a direction parallel to the horizontal direction, In addition, a second lateral direction (also referred to as "front-back direction") D2 is orthogonal to the first lateral direction D1, and a third direction D3 is a vertical direction orthogonal to the first lateral direction D1 and the second lateral direction D2. This is the vertical direction D3.

Although the person conveyor 1 according to the present embodiment is an escalator whose tread surface has a step-like shape in order to convey people, it is not limited to such a configuration. For example, the person conveyor 1 may be a moving walkway (moving walkway) whose tread surface is flat in order to transport people.

The structure 2 may include, for example, machine chambers 2a, 2a arranged at each end in the second lateral direction D2, as in the present embodiment. Further, the structure 2 may have, for example, a truss structure or a girder structure composed of a plurality of frame members.

The passenger conveyor 1 may include, for example, a floor plate 1a attached to the structure 2 so as to cover the machine rooms 2a, 2a from above, as in the present embodiment. Thereby, the floor plate 1a constitutes getting on/off parts 1b, 1b arranged at each end of the conveying part 3 in the second lateral direction D2 in order to get on and off the conveying part 3.

For example, as in the present embodiment, the conveyance section 3 includes an endless annular running section 3a that rotates and runs by being driven by the drive section 5, and a running section 3a that is connected to the running section 3a and runs together with the running section 3a.

Note that, for example, the handrail belt 4a may be driven by the drive unit 5, and the running of the handrail belt 4a may be synchronized with the running of step 3b.

As shown in FIGS. 1 and 2, the drive unit 5 may include, for example, a motor 7 and a transmission unit 8 that transmits the drive of the motor 7 to the transport unit 3. The transmission section 8 includes a first rotating section 9 that rotates by the drive of the motor 7, and a second and second rotating section 9 that rotates about the first lateral direction D1 and around which the running section 3a is wound such that the step 3b is reversed. It may include three rotating parts 10 and 11 and a transmission member 12 that transmits the drive of the first rotating part 9 to the second rotating part 10.

As a result, the first to third rotating parts 9, 10, and 11 are rotated by receiving the drive of the motor 7, so that the drive of the motor 7 can be transmitted to step 3b. Therefore, step 3b is driven by the motor 7. Note that the first rotating section 9 may be indirectly driven by the motor 7 via, for example, a speed reducer, or may be driven directly from the motor 7, for example. .

The transmission material 12 may be, for example, an annular member (for example, a chain, a belt, etc.) wound around the first rotating section 9 and the second rotating section 10, respectively, as in the present embodiment. Note that the configuration is not limited to this, and for example, the first rotating section 9 may directly mesh with the second rotating section 10 without using the transmission member 12. That is, the first rotating section 9 and the second rotating section 10 may be gear mechanisms.

As shown in FIG. 2, the passenger conveyor 1 includes, for example, a speed detection section 13 that detects the rotation speed of the second rotation section 10, a direction detection section 14 that detects the rotation direction of the second rotation section 10, and a first A first brake 16 that brakes the rotation of the rotating section 9 and a second brake 17 that brakes the rotation of the second rotating section 10 may be provided.

Note that the speed detection section 13 indirectly detects the rotation speed of the second rotation section 10 by detecting the rotation speed of the first rotation section 9, the rotation speed of the third rotation section 11, and the running speed of step 3b. You may.

The direction detection unit 14 is not particularly limited, but may be, for example, various sensors (for example, a proximity sensor, a photoelectric sensor) that detect teeth on the outer periphery of the second rotation unit 10, or, for example, It may be a rotation detection sensor (for example, an encoder) that detects 10 rotations. Note that the direction detection unit 14 indirectly detects the rotation direction of the second rotation unit 10 by detecting the rotation direction of the first rotation unit 9, the rotation direction of the third rotation unit 11, and the running direction of step 3b. You may.

Further, the members forming the speed detecting section 13 may be the same as the members forming the direction detecting section 14, for example, as in this embodiment. That is, the speed detection section 13 may also serve as the direction detection section 14. Note that the configuration is not limited to this, and the member constituting the speed detecting section 13 may be a separate member from the member constituting the direction detecting section 14, for example.

Although not particularly limited, the first brake 16 may be configured to be able to brake the rotation of the first rotating part 9 regardless of whether the first rotating part 9 rotates, for example, by operating. Although not particularly limited, the first brake 16 may be, for example, a disc brake that generates braking force (frictional force) by sandwiching a disc, or may be, for example, a disc brake that pressurizes and contacts the outer or inner periphery of the drum. It is also possible to use a drum brake that generates braking force (frictional force).

As shown in FIGS. 2 and 3, the second rotating part 10 includes, for example, a rotating shaft 10a, a first rotating main body part 10b wrapped around the running part 3a, and a second rotating main body part 10b wrapped around the transmission material 12. part 10c, and a first fixing part 10d that fixes the first rotating body part 10b and the second rotating body part 10c. As a result, the first rotating main body section 10b and the second rotating main body section 10c are immovably fixed to each other and rotate together around the rotating shaft 10a.

Further, the second rotating section 10 is arranged in rotational directions D4 and D5 (rotational direction of the second rotating section 10) with respect to the first rotating main body section 10b and the second rotating main body section 10c, for example, as in the present embodiment. It may include a rotatable movable part 10e and a pressurizing part 10f that pressurizes the movable part 10e into contact with the second rotating main body part 10c.

For example, as in the present embodiment, the movable part 10e includes a movable main body part 10g disposed between the second rotating main body part 10c and the pressing part 10f, and the pressing part 10f is connected to the second rotating main body part 10f. It may be configured to include a sandwiching part 10h that sandwiches the movable main body part 10g between the movable main body part 10c and a second fixing part 10i that fixes the sandwiching part 10h and the second rotating main body part 10c.

Further, the second rotating section 10 includes, for example, friction materials 10j between the movable main body section 10g and the second rotating main body section 10c and between the movable main body section 10g and the sandwiching section 10h, respectively, as in the present embodiment. You can leave it there. For example, as in the present embodiment, when step 3b transports a person downward, the second rotating section 10 rotates in the first rotation direction D4, and when step 3b transports a person upward, the second rotating section 10 rotates in the first rotation direction D4. , the second rotating section 10 may be configured to rotate in the second rotation direction D5.

The second rotating portion 10 may include, for example, a protruding portion 10k as in this embodiment. For example, the protruding portion 10k may protrude from the movable main body portion 10g in the direction (first lateral direction) D1 in which the rotating shaft 10a extends, as in the present embodiment. Further, for example, as in the present embodiment, a plurality of protrusions 10k may be provided at intervals in the rotation directions D4 and D5, or, for example, only one protrusion portion 10k may be provided.

For example, as in the present embodiment, the second brake 17 may include a stop portion 17a that abuts against the protrusion 10k in the first rotation direction D4, and an operating portion 17b that operates the stop portion 17a. good. For example, as in the present embodiment, the operating section 17b connects an operating source (for example, an electromagnetic cylinder) 17c, the operating source 17c, and the abutting section 17a, and moves the abutting section 17a by the operation of the operating source 17c. The connection link 17d may also be provided.

As a result, the abutting portion 17a moves between the abutting position where the protruding portion 10k is abutted (the position shown in FIGS. 2 and 3) and the retracted position (not shown) where it is separated from the protruding portion 10k. Then, the stop portion 17a is located at the stop position, and the stop portion 17a stops the protrusion 10k in the first rotation direction D4, thereby stopping the rotation of the second rotating portion 10. At this time, a frictional force is generated between the movable portion 10e and the second rotating main body portion 10c.

Note that the configurations of the second rotating section 10 and the second brake 17 are not particularly limited. For example, the second rotating portion 10 includes a protruding portion 10k that protrudes outward in the radial direction, and the second brake 17 includes a stop portion 17a that abuts and stops the protruding portion 10k in the rotational direction D4. , it may be configured as follows.

Furthermore, although not particularly limited, in the present embodiment, when the second rotating portion 10 rotates in the first rotation direction D4, the abutting portion 17a stops the protrusion 10k by being located at the abutting position. However, when the second rotating part 10 rotates in the second rotation direction D5, the stop part 17a is configured such that it cannot stop the protrusion 10k even if it is located at the stop position. be.

For example, in the present embodiment, when the abutting part 17a located at the abutting position hits the protrusion 10k of the second rotating part 10 rotating in the second rotation direction D5, the abutting part 17a By receiving the rotational force of the rotating part 10, it moves toward the retracted position, that is, it is not held at the stop position. Note that the configuration is not limited to this, and regardless of whether the second rotating portion 10 is rotating in the first rotation direction D4 or the second rotation direction D5, the stop portion 17a protrudes by being located at the stop position. It may be configured such that the portion 10k can be held against the portion 10k.

As shown in FIG. 4, the passenger conveyor 1 includes, for example, a torque detection section 18 that detects the torque of the motor 7, and a boarding section 1b (particularly a boarding section for a person to get on the conveyance section 3) that detects a person. It may include a person detection section 19, an input section 20 into which various information is input, and an output section 21 through which various information is output.

The processing unit 6 includes, for example, an acquisition unit 6a that acquires each piece of information (data) from each unit 13 to 14 and 18 to 20, a storage unit 6b that stores each piece of information, and a storage unit 6b that calculates each piece of information or performs processing based on each piece of information. It may also include a calculation unit 6c that performs determination and a control unit 6d that controls each unit 7, 16, 17, and 21.

Note that the processing unit 6 includes, for example, processors such as a CPU and MPU (for example, a calculation unit 6c, a control unit 6d), memories such as ROM and RAM (for example, an acquisition unit 6a, a storage unit 6b), various interfaces (for example, The computer may be equipped with an acquisition unit 6a) or the like. As a result, each section 6a to 6d of the processing section 6 is realized by the processor executing the program stored in the memory and the software and hardware working together.

Further, the processing unit 6 may be configured by, for example, one device, or may be configured by, for example, a plurality of devices that can communicate with each other. Specifically, each of the units 6a to 6d of the processing unit 6 may be included in one device, or may be distributed and included in a plurality of devices that can communicate with each other, for example.

The configuration of the torque detection section 18 is not particularly limited. The torque detection unit 18 may, for example, directly detect the output torque of the motor 7, or may detect information that has a correlation with the output torque of the motor 7 (for example, the output torque of the motor 7 (for example, output power, output voltage, current, etc.) of an inverter for the motor 7), and the output torque of the motor 7 may be indirectly detected.

The input unit 20 includes, for example, as in the present embodiment, a start/stop input unit 20a into which information about the running in step 3b is input, and a running direction input unit 20b into which information about the running direction in step 3b is input. You can leave it there. Further, the output unit 21 may include a display unit 21a that outputs information on a display, for example, as in this embodiment.

As shown in FIG. 5, the start/stop input unit 20a may receive, for example, start instruction information that is an instruction to start running in step 3b, and stop instruction information to stop running in step 3b. Although not particularly limited, the start/stop input section 20a may be, for example, a key lock switch that is disposed on the cover section 4c of the parapet section 4 and can be rotated by inserting a key, as in the present embodiment.

Note that the input unit 20 is not limited to such a configuration, and may include a start input unit into which start instruction information is input, and a stop input unit into which stop instruction information is input. That is, for example, a member (for example, a switch) to which start instruction information is input may be a separate member from a member (for example, a switch) to which stop instruction information is input.

The running direction input unit 20b receives first direction instruction information that is an instruction to run step 3b in a first direction (downward), and second direction instruction information that is an instruction to run step 3b in a second direction (upward). information may be input. Although not particularly limited, the traveling direction input section 20b may be, for example, a key lock switch that is disposed on the cover section 4c of the handrail section 4 and can be rotated by inserting a key, as in the present embodiment.

Note that the input unit 20 is not limited to such a configuration, and may include a first direction input unit into which the first direction instruction information is input, and a second direction input unit into which the second direction instruction information is input. good. That is, for example, the member (for example, a switch) into which the first direction instruction information is input may be a separate member from the member (for example, a switch) into which the second direction instruction information is input.

The display section 21a is not particularly limited, but may be, for example, a liquid crystal display lamp disposed on the cover section 4c of the balustrade section 4 as in the present embodiment. When the boarding section 1b is an exit, the display output section 21a may display, for example, an arrow indicating that entry is possible, and when the boarding section 1b is an exit, the display section 21a may display, for example, an arrow indicating that entry is possible. For example, a mark indicating that entry is prohibited may be displayed.

The configuration of the person detection unit 19 is not particularly limited. The person detection unit 19 may be, for example, a photoelectric sensor (e.g., reflective type, transmissive type) as in the present embodiment, or may be an image sensor (e.g., camera), or may be, for example, a It may also be a weight sensor (for example, a load cell) that detects.

The configuration of the passenger conveyor 1 according to the present embodiment is as described above, and next, the control of the passenger conveyor 1 according to the present embodiment will be explained with reference to FIG. 6. Note that the following control contents are exemplified to help understand the control of the passenger conveyor 1, and do not limit the control of the passenger conveyor 1.

First, when start instruction information is input to the start/stop input section 20a, the processing section 6 enters the passenger conveyor operation and performs travel control in step 3b. Although not particularly limited, the traveling control in step 3b may be, for example, constant speed traveling control, or may be, for example, automatic start/stop control.

In the constant speed traveling control, for example, after starting the traveling in step 3b, the processing unit 6 sets the traveling speed in step 3b to the rated speed (for example, 30 m/min) and maintains that state, although it is not particularly limited. It's okay. Thereby, for example, regardless of whether the person detection unit 19 detects a person, step 3b continues running at a constant speed (rated speed).

Further, in the automatic start/stop control, although not particularly limited, for example, when the person detection unit 19 detects a person, the processing unit 6 starts running in step 3b and changes the running speed in step 3b to the rated speed. You may also do so. Then, when a predetermined time (for example, 30 seconds added to the time it takes for step 3b to travel the distance of 1/2 lap) has passed since the person detection unit 19 last detected a person, the processing unit 6 may stop running in step 3b.

Thereby, the step 3b can be run as necessary, so that energy-saving operation can be performed. Note that if step 3b is stopped while automatic start/stop control is being performed, for example, the first brake 16 is operating while the second brake 17 is not operating, that is, the current brake is not operating. The stop portion 17a may be located at a retracted position.

By the way, as shown in FIG. 6, during operation of the passenger conveyor, when stop instruction information is input to the start/stop input section 20a ("Y" in S1), the rotation direction of the second rotating section 10 changes to the second direction. If the rotation direction is D5 (“N” in S2), the processing unit 6 changes the rotation direction of the second rotation unit 10 to the first rotation direction D4 by controlling the motor 7 (S3).

As a result, in step 3b, the robot travels in the direction of transporting the person downward before stopping. Note that when the stop instruction information is input to the start/stop input section 20a during operation of the passenger conveyor ("Y" in S1), when the rotation direction of the second rotation section 10 is the first rotation direction D4, (“Y” in S2), the processing unit 6 maintains the rotation direction of the second rotation unit 10 in the first rotation direction D4.

Then, when the rotational speed of the second rotating part 10 becomes equal to or lower than the set speed ("Y" in S4), the processing part 6 moves the stopper part 17a from the retracted position to the stopper position (S5). Note that, although not particularly limited, the set speed may be, for example, 10% or less of the rated speed (the rotational speed of the second rotating section 10 when the traveling speed in step 3b is the rated speed).

As a result, when the abutment part 17a abuts and stops the protrusion 10k, the rotational speed of the second rotating part 10 is lower than the set speed, so for example, the abutment part 17a abuts and stops the protrusion 10k. The impact can be reduced. At this time, the motor 7 tries to bring the rotational speed of the second rotating part 10 to the set speed with the abutting part 17a abutting and stopping the protruding part 10k, so the output torque of the motor 7 becomes large. The rotational speed of the second rotating section 10 becomes zero.

Therefore, the processing unit 6 determines that the output torque detected by the torque detection unit 18 is equal to or higher than the set value (“Y” in S6), and the rotational speed of the second rotating unit 10 detected by the speed detection unit 13 is , becomes zero (“Y” in S7), the processing unit 6 operates the first brake 16 (S8) and stops the output of the motor 7 (S9). As a result, the first brake 16 is operated after the abutting portion 17a abuts and stops the protrusion 10k.

Therefore, when the rotation of the first and second rotating parts 9 and 10 is stopped by braking of the first and second brakes 16 and 17, the stop part 17a is brought into a state where it rests against the protrusion part 10k. I can do it. As a result, for example, when the passenger conveyor 1 is used as a staircase, the steps 3b can be prevented from moving due to the weight of the person using the staircase.

Note that, although not particularly limited, in such a state, when start instruction information is input to the start/stop input section 20a, the second rotating section 10 first rotates in the second rotation direction D5, and then rotates to the stop stop. The portion 17a may be moved from the stop position to the retracted position. Thereby, for example, the stop portion 17a can be moved smoothly.

If step 3b transports the person downward (the first direction instruction information is input to the traveling direction input section 20b), then the rotation direction of the second rotation section 10 is changed to the first rotation direction D4. Can be switched. On the other hand, when step 3b transports the person upward (the second direction instruction information is input to the traveling direction input section 20b), the rotation direction of the second rotation section 10 is maintained in the second rotation direction D5. be done.

As described above, the passenger conveyor 1, as in the present embodiment, includes a motor 7, a step 3b that travels by the drive of the motor 7, and a first rotating step 3b that rotates in order to transmit the drive of the motor 7 to the step 3b. and second rotating parts 9 and 10, a first brake 16 that brakes the rotation of the first rotating part 9, a second brake 17 that brakes the rotation of the second rotating part 10, and a second brake 17 that brakes the rotation of the second rotating part 10, and The second rotating section 10 includes an input section 20 into which stop instruction information to stop is input, and a processing section 6 that controls the motor 7, the first brake 16, and the second brake 17. The second brake 17 is provided with a protrusion 10k, and the second brake 17 is arranged between a stop position where the protrusion 10k is stopped in order to brake the rotation of the second rotating part 10, and a retracted position where the protrusion 10k is separated from the protrusion 10k. The processor 6 includes a movable abutment part 17a, and when stop instruction information is input to the input part 20, the processing part 6 moves the abutment part 17a from the retracted position to the abutment position. A configuration in which the first brake 16 is operated is preferable.

According to this configuration, when the stop instruction information is input to the input unit 20, the stop portion 17a moves from the retracted position to the stop position, and then the first brake 16 operates. Thereby, when the rotation of the first and second rotating parts 9 and 10 is stopped by braking of the first and second brakes 16 and 17, the stop part 17a is in a state where it rests against the protrusion part 10k. It's easy.

[2]
Further, the passenger conveyor 1 of [1] above includes a torque detection section 18 that detects the output torque of the motor 7, as in the present embodiment, and the processing section 6 receives stop instruction information from the input section 20. When the input is received, the stop portion 17a is moved from the retracted position to the stop position, and after the output torque detected by the torque detection portion 18 exceeds a set value, the first brake 16 is activated. It is preferable to have a configuration in which it is operated.

According to such a configuration, when stop instruction information is input to the input unit 20, the stop portion 17a moves from the retracted position to the stop position, and the output torque detected by the torque detection portion 18 exceeds the set value. After this occurs, the first brake 16 operates. Thereby, when the rotation of the first and second rotating parts 9 and 10 is stopped by braking of the first and second brakes 16 and 17, the stop part 17a is brought into a state where it rests against the protruding part 10k. be able to.

[3]
Further, the passenger conveyor 1 according to [1] or [2] above includes a speed detecting section 13 that detects the rotational speed of the second rotating section 10 as in the present embodiment, and the processing section 6 When stop instruction information is input to the input unit 20, the rotational speed of the second rotation unit 10 detected by the speed detection unit 13 by moving the stop part 17a from the retracted position to the stop position. It is preferable that the first brake 16 is operated after the first brake 16 becomes zero.

According to such a configuration, when the stop instruction information is input to the input unit 20, the stop portion 17a moves from the retracted position to the stop position. Then, after the rotational speed of the second rotating section 10 becomes zero, the first brake 16 operates. Thereby, when the rotation of the first and second rotating parts 9 and 10 is stopped by braking of the first and second brakes 16 and 17, the stop part 17a is brought into a state where it rests against the protruding part 10k. be able to.

[4]
Further, the passenger conveyor 1 according to any one of [1] to [3] above includes a speed detection section 13 that detects the rotation speed of the second rotation section 10, and the processing section 6 When the stop instruction information is input to the input section 20, the stop section 17a is activated after the rotational speed of the second rotating section 10 detected by the speed detection section 13 becomes equal to or less than the set speed. It is preferable to move from the retracted position to the stop position.

According to such a configuration, after the rotational speed of the second rotating portion 10 becomes equal to or lower than the set speed, the stop portion 17a moves from the retracted position to the stop position. Thereby, when the abutting part 17a abuts against the protruding part 10k, the rotational speed of the second rotating part 10 can be made equal to or less than the set speed.

Further, in the person conveyor 1 according to any one of [1] to [4] above, as in the present embodiment, the second rotating section 10 is configured to rotate the second rotating section 10 when transporting the person downward in step 3b. The abutment part 17a rotates in one rotational direction D4, and when the second rotation part 10 rotates in the first rotational direction D4, the abutment part 17a stops the protrusion part 10k by being located at the abutment position. is possible, and the processing unit 6 controls the processing unit 6 when stop instruction information is input to the input unit 20 when the second rotation unit 10 rotates in a second rotation direction D5 opposite to the first rotation direction D4. , the motor 7 is controlled so that the second rotating part 10 rotates in the first rotating direction D4, and after the second rotating part 10 rotates in the first rotating direction D4, the stop part 17a It is preferable that the retractor is moved from the retracted position to the stop position.

According to such a configuration, when the stop instruction information is input to the input unit 20 when the second rotating unit 10 rotates in the second rotation direction D5, the rotation direction of the second rotating unit 10 is changed. After the second rotating portion 10 rotates in the first rotation direction D4, the stop portion 17a moves from the retracted position to the stop position. Thereby, the second brake 17 brakes the rotation of the second rotating section 10 in the first rotation direction D4.

Note that the passenger conveyor 1 is not limited to the configuration of the embodiment described above, nor is it limited to the effects described above. Moreover, it goes without saying that the passenger conveyor 1 may be modified in various ways without departing from the gist of the present invention. For example, it goes without saying that one or more of the configurations, methods, etc. according to the various modification examples described below may be arbitrarily selected and adopted as the configurations, methods, etc. according to the above-described embodiments.

(A) In the passenger conveyor 1 according to the above embodiment, when the output torque of the motor 7 exceeds the set value and the rotational speed of the second rotating section 10 becomes zero, The configuration is such that the brake 16 is operated. However, the passenger conveyor 1 is not limited to such a configuration.

For example, the processing unit 6 may be configured to operate the first brake 16 regardless of the rotational speed of the second rotating unit 10 when the output torque of the motor 7 exceeds a set value. Further, for example, the processing unit 6 may be configured to operate the first brake 16 when the rotational speed of the second rotating unit 10 becomes zero, regardless of the output torque of the motor 7.

For example, the processing unit 6 operates the first brake 16 when a predetermined time has elapsed after moving the stop portion 17a, regardless of the output torque of the motor 7 and the rotational speed of the second rotation unit 10. It may also be configured such that the For example, regardless of the output torque of the motor 7 and the rotational speed of the second rotating unit 10, the processing unit 6 controls the first rotating unit when the second rotating unit 10 rotates by a predetermined amount after moving the stop portion 17a. A configuration in which the brake 16 is operated may also be used.

Then, when the rotation of the first and second rotating parts 9 and 10 is stopped by braking of the first and second brakes 16 and 17, the stop part 17a is in a state where it is brought into contact with the protruding part 10k. However, depending on the timing of the operation of the first and second brakes 16 and 17, for example, the stop portion 17a may be slightly separated from the protrusion 10k.

(B) In the passenger conveyor 1 according to the above embodiment, the processing unit 6 moves the stop part 17a from the retracted position to the stop position when the rotation speed of the second rotating part 10 becomes lower than the set speed. The configuration is to move it to . However, the passenger conveyor 1 is not limited to such a configuration. For example, the processing unit 6 may be configured to move the stop portion 17a from the retracted position to the stop position while the rotational speed of the second rotating portion 10 remains at the rated speed.

(C) Furthermore, in the passenger conveyor 1 according to the embodiment described above, the processing unit 6 controls the processing unit 6 when stop instruction information is input to the input unit 20 when the second rotating unit 10 rotates in the second rotation direction D5. After the second rotation part 10 rotates in the first rotation direction D4, the stop part 17a is moved from the retracted position to the stop position. However, the passenger conveyor 1 is not limited to such a configuration.

When the stop instruction information is input to the input unit 20 when the second rotating unit 10 rotates in the second rotating direction D5, the processing unit 6 controls the state in which the second rotating unit 10 rotates in the second rotating direction D5. In this case, the stop portion 17a may be moved from the retracted position to the stop position. In such a configuration, regardless of whether the second rotating portion 10 is rotating in the first rotation direction D4 or the second rotation direction D5, the stop portion 17a is located at the stop position to prevent the protrusion portion 10k from moving. It has a structure that allows it to be stopped.

(D) For example, the execution order of each process such as the operation, procedure, step, and stage in the system, method, program, and apparatus shown in the claims, specification, and drawings is the output of the previous process. They can be implemented in any order as long as they are not used in subsequent processing. For example, even if "first", "next", etc. are used in the explanation for convenience, this does not mean that execution in this order is essential.
