More specifically, as shown in FIG. 4, the second shaft 7 has a shaft 25 having guide plates 26 attached to both ends thereof, one end of which is fixed to the gear 24, and both ends of which are fitted in bearings 27. The gear 24 is rotatably supported.
The gear 30 is engaged with the gear 30 incorporated into the first shaft 29 via the first one-way rotation clutch 22. The updating means described above includes, for example, the first shaft body 6, the second shaft body 7, and the gear 2
3, 24.

The shaft 3 of the driving motor 21 is connected to the gear 3 via the second one-way rotating clutch 30 as described above.
1 is engaged with the wire drive gear 32. The wire 3 is connected to the wire drive gear 32 by a pin 40.
One end of 7 is fixed, the contact means is operated via the wire 37 by the rotation of the wire drive pulley 32, and the moving handrail movement detecting means 33 is controlled.

That is, in the moving handrail movement detecting means 33, the rotating pulley 42 which can be brought into contact with the moving handrail 1 is fixed to a mounting base 35 rotatably supported on the main body case 4 via the pin 34. The mounting base 35 has an arm 3
The other end of the wire 37 is fixed to the tip of the arm 36 by a pin 38. This wire 37 is connected to a wire drive gear 32 via an idler pulley 39. Then, a pressing force is applied to the rotating pulley 42 in the direction of the moving handrail 1 by the spring 41. The abutment means includes, for example, a mounting base 35, a wire 37, a wire drive gear 32, and a gear 31.

The pressing means 8 includes a pressing table 60 in contact with the cleaning tool 5 and a pressing shaft 61 for supporting the pressing table 60.
And the eccentric cam 28 provided below the pressing shaft 61.

With such a configuration, when the operation of the passenger conveyor is started, first, the control means 11 outputs a detection command to energize the motor 21 and to apply a dotted arrow 52
, And the wire drive gear 32 is
To stop the pin 40 at the position of 40 "by rotating the pulley 4 by the force of the spring 41.
The moving handrail 1 is rotated by being pressed by the moving handrail 1, and the moving handrail movement detecting means 33 detects the moving direction and speed of the moving handrail 1. Based on the detection result, the control unit 11 outputs a cleaning start command to energize a motor (not shown) connected to the eccentric cam 28. On the other hand, when the detection by the moving handrail movement detecting means 33 is completed, the drive motor 21 is driven by the dashed arrow 53 by the end command from the control means 11.
The pin 40 is further rotated by に in the direction shown in FIG. As a result, the wire 37 becomes the most pulled position, and the moving handrail movement detecting means 33 becomes 33 '.
It is lowered to the state of. During the operation of the moving handrail movement detecting means 33, the other gear 23 meshing with the driving motor 21 idles via the one-way rotating clutch 22 so as not to obstruct the updating means of the cleaning tool 5. There is no. Further, as a characteristic of the one-way rotation clutch 22, a reaction force from the load side, that is, an upward force by the spring 41 when the moving handrail movement detection means 33 is lowered is held by the reverse rotation preventing force.

In response to the cleaning start command, the control means 11 operates a motor (not shown) to rotate the eccentric cam 28 and push up the pressing table 60 via the pressing shaft 61 in the direction of the moving handrail 1. As a result, the cleaning tool 5 hung on the upper surface of the pressing table 60 is pressed by the moving handrail 1, and slides and cleans as the moving handrail 1 moves. At this time, a force is applied to the cleaning tool 5 in a direction opposite to the winding direction due to the frictional resistance due to the sliding contact with the moving handrail 1, but one end of the cleaning tool 5 is incorporated in the gear 31 connected thereto. It is held by the reverse rotation preventing force of the directional rotation clutch 30. Further, since the cleaning tool 5 passes through the cleaning liquid tank 10, the cleaning tool 5 contains cleaning liquid and can be effectively cleaned.

Thereafter, when the set cleaning time elapses and the renewal timing of the cleaning tool 5 is reached, the control means 11 outputs a renewal command and the motor (not shown) and the driving motor 21 connected to the eccentric cam 28 are driven. Energize each. In response to this, first, the motor operates to rotate the eccentric cam 28, and the pressing table 60 is pulled down via the pressing shaft 61 in a direction away from the moving handrail 1. Next, the driving motor 21
Rotates the gears 23, 24 in the directions of the solid arrows 50, 51, and winds up the used cleaning tool 5 from the freely rotating first shaft body 6. At this time, the other gear 31 that meshes with the driving motor 21 is idling through the one-way rotation clutch 30 and does not support the contacting means.

When the winding is completed in this manner, the control means 11 rotates the cam 28 of the pressing means 8, and presses the cleaning tool 5 against the moving handrail 1 to start cleaning the moving handrail 1 again . Et al is, one driving source, i.e., by allowing the operation of each of the update means and the contact means by the driving motor 21, achieving reduction in number of parts, that a device of low cost, and simple construction Can be. Furthermore, simple one-way rotating clutches 22 and 30
The reverse rotation inhibiting force holds the reaction force, that is, the friction force with the moving handrail 1 acting on the cleaning tool 5 and the repulsion force of the spring 41, so that there is no need to provide another brake mechanism, and the number of parts is small. And a highly reliable device can be obtained. In addition, since the number of drive sources should be two, the operation time of the drive motor 21 is doubled, but the operation time of the drive motor 21 is small in view of the operation time of the cleaning device itself. There is no problem.
