[Prior Art] For example, the passenger conveyor proposed in Patent Document 1 generally has a structure in which the height of the passenger conveyor is reduced, in particular, the height of the casing is reduced. In other words, in the passenger conveyor disclosed in Patent Document 1, the reduction gears constituting the drive device and the drive motor are arranged side by side in the lateral direction to reduce the height dimension of the entire drive device. [Patent Document 1] JP-A-58-109375 (Fig. 5, Fig. 6) [Explanation] [Problems to be Solved by the Invention] According to the above-described conventional technique, the height dimension of the driving device can be reduced. Chemical. However, even if the height dimension of the driving device is reduced, for example, the driving sprocket and the driven sprocket of the pedal direction converting portion are still the same size as the transmission structure, so that the height dimension of the passenger conveyor cannot be reduced, in particular, Reduce the height of the frame. It is an object of the present invention to provide a passenger conveyor that can reduce the height dimension of the frame by -5 - 1262891 (2). [Means for Solving the Problem] In order to achieve the above object, in order to achieve the above object, the depth dimension of the pedal is three times or less the diameter of the running wheel that is pivotally supported by the pedal, and the gear that constitutes the driving device is configured via the flexible body. The power transmission of the speed reducer and the drive motor is transmitted, and the power sprocket, the gear reduction device, and the drive motor driven by the drive device are arranged along the long axis direction of the casing of the passenger conveyor in a plan view. . By arranging the gear reduction device and the drive motor in the above-described configuration in the longitudinal direction of the casing in a plan view, the gear reduction device and the drive motor are not overlapped in the vertical direction, thereby reducing the gear reduction device and the drive motor. As the height dimension of the drive unit. By transmitting the power of the gear reduction device and the drive motor in the above configuration via the flexible body, even if the center of the input shaft of the gear reduction device is offset from the center of the output shaft of the drive motor, the gear reduction device can be used. The other side is disposed within the height range of one side of the drive motor. Thereby, the height dimension of the driving device is determined by the high height dimension of the gear reduction device and the driving motor, and the height dimension of the casing does not increase due to the increase in the height dimensions of the two. In addition, by making the depth dimension of the pedal in the above configuration three times or less the diameter of the running wheel of the pedal, even if the driving sprocket or the driven sprocket are made small diameter, the direction is changed. At the same time, the adjacent pedal is not interfered, and as a result, the height dimension of the pedal direction changing portion can be reduced. Therefore, since the driving size of the driving device -6-(3) 1262891 which determines the height of the housing is set to be different from the height of the pedal direction changing portion, the height of the housing can be reduced. [Embodiment] Hereinafter, a first embodiment of the present invention will be described based on electric roads ′ shown in Figs. 1 to 3 . The electric path 2 provided on the floor 1 is a pedestal that houses the casing 3 housed in the recess 1P formed in the floor 1. The frame body 3 has lift tables 4A and 4B on the same surface as the floor surface 1 at both end portions in the longitudinal direction, and the drive sprocket 5 and the follower are axially supported below the lift tables 4A and 4B. Sprocket 6. The drive sprocket 5 has a pair of drive sprocket wheels 5 A and 5 B fixed to each other on the drive shaft 7, and similarly, a pair of the driven sprocket wheels 6 are fixed to the rotary shaft 6 S. The drive shaft 7 and the rotary shaft 6 S are rotatably supported by the frame body 3 via bearings 8A and 8B, respectively. Between the pair of drive sprocket wheels 5 A, 5 B and the pair of driven sprocket 6 , a pair of circulating pedal chains 9 are wound around, and a plurality of pedals 〇 are connected to each other. Pedal chain 9. As shown in Fig. 2, the pedal 1 〇' axially supports the running wheel 11 at a fixed position on one side in the depth direction, and the other end in the depth direction is provided to protrude toward the adjacent pedal side for holding The bearing 1 2 of the axle of the running wheel of the adjacent pedal. The bearing 12 has a concave groove that is parallel to the depth direction of the pedal and that opens to the adjacent pedal side, so that the 1262891 (4) axle of the running wheel adjacent to the pedal is engaged and slid to the concave groove. The running wheel n is formed to be guided by a guide rail (not shown) laid in the casing 3, and is moved between the two lifting tables 4A, 4B. The longitudinal dimension L of the pedal 10 is formed to be three times or less the length of the diameter D r of the running wheel 11 and is formed by the depth dimension L of the pedal 10 as the diameter Dr of the running wheel 1 1 . Three times or less, the diameter DS of the drive sprocket 7 and the 彳At moving sprocket 6 can be formed to be twice or less the depth dimension L of the pedal 1 , and more than twice the height dimension Η. In the frame body 3 facing the both sides of the pedal 10, a railing portion 13 is erected along the moving direction of the pedal 1 ,, and the moving armrest 14 is guided at the peripheral portion of the railing portion 13 It can move. The moving handrail 14 is driven below the railing portion 13 by the hand driving device 15 to be moved in the same direction at a speed synchronized with the pedal 1 。. The handrail driving device 15 presses the front and back of the moving handrail 14 by the driving roller 16 and the driven prodigal member 17. The sprocket 1 is fixed coaxially with the drive roller 116, and by rotating the sprocket 18, the drive roller 16 is rotated toward the driven roller 17 to drive the movement. Handrail 1 4. The sprocket 18 is driven to obtain the power from the drive shaft 7 to drive the drive roller 16. In other words, the power sprocket 17 for driving the handrails provided between the drive sprocket wheels 5 A and 5 of the drive shaft 7 is provided to be driven closer to the handrail than the drive shaft 7 The intermediate sprocket 2 1 of the intermediate shaft 20 on the side of the device 1 5, the connecting chain 2 2 wound around the power sprocket 19 and the intermediate sprocket 2 1, and the two -8- (the intermediate shaft 20 provided above) 5) 1262891 A pair of handrail drive sprocket 2 3 A, 2 3 B at the end, and between the handrail drive sprocket 23 A, 23B and the sprocket 18 of the above-mentioned sub-segment 6 via the double sprocket 24 The drive chain 25 is configured to transmit the above-described driving power to the handrail driving device 15. On the other hand, the means for applying power to the drive shaft 7 is: a wheel 26 that is fixed closer to the shaft end side than the above-described drive sprocket 5 B, a driving device 27, and a communication power sprocket 26 The power transmission chain with the power of 2 to 7 is 28. The drive unit 27 includes, for example, an electric motor 29 such as an induction motor and a reduction gear 30, and the structure is fixed to the casing 3 via a common one. The drive motor 29 is reduced by 3 〇, and the drive motor 2 is disposed along the longitudinal direction of the casing 3 in plan view. The flywheel 3 2 and the small pulley are provided on the rotary shaft. Pulley 34 and output pulley 35. Between the small pulley 3 3 of the drive motor 29 and the reduction gear 30 pulley 34, for example, a V-belt 3 6 wound around 3 to 4 strings is wound around the power transmission chain 28 of the power sprocket 26 The output sprocket 35 wound around the set 30 drives the power transmission shaft 7 of the motor 29 to drive the pedal 10 and the moving handrail 14. The transmission of the power of the drive motor 29 to the reduction gear unit 3 is not limited to the use of the small pulley 3 3 and the input pulley 34 and the V-belt. For example, it is also possible to use a power transmission flexible body, that is, a toothed portion. The belt, and the sprocket or pulley wound around the sprocket or the pulley in the frame 3 provided with the driving device 27, is the number of the driving roller 7 which is driven by the power chain drive. The device, the input on the 33, is driven by the speed reduction device 36, and the chain or the raft has a built-in 1226891 (6) control device 37 for controlling the operation of the electric road 2. According to this embodiment, since the drive motor 29 and the reduction gear 30 of the drive unit 27 are arranged along the longitudinal direction of the casing 3 so as not to overlap in the plan view, the drive can be reduced. The height dimension of the device 27 and the height dimension of the frame 3 can be reduced. In the conventional structure, the drive motor 29 and the reduction gear 30 do not overlap each other, and the rotation shaft of the drive motor 29 is coupled or integrated with the input shaft of the reduction gear 30. However, the above-mentioned drive motor 29 or the above-described reduction gear unit 30 has a large difference in the position of the size of the rotation shaft or the input shaft in the height direction, so that when the shaft is coupled or integrated, the drive is driven. The height dimension of the device 27 is increased. In other words, in the first figure, the input shaft (input pulley 34) of the reduction gear 30 that is lower in height than the rotation shaft (small pulley 33) of the drive motor 29 is integrated or integrated. At this time, the attachment of the drive motor 29, that is, the flywheel 3 2 is a flywheel 32S which is positioned like a two-dot dotted line and protrudes below the frame 3. In order to eliminate this protrusion, in addition to the necessity of supporting the drive motor 29 and the reduction gear 30 to the individual bases, it is also necessary to fix them in the frame 3, so that the drive unit 27 is disposed in the frame 3. Complicated, it requires a lot of complicated production. Therefore, according to the present embodiment, in addition to the fact that the drive motor 29 and the reduction gear 30 do not overlap in the plan view, it is important to transmit the power by the flexible body. Further, since the small pulley 3 3 of the drive motor 29 and the input pulley 3 4 and the output sprocket 35 of the reduction gear 30 are directed toward the power sprocket 26 side, -10- (7) 1262891 is wound thereon. The moving body is the power transmission chain 2 8 and the v-type belt 3 6 , so the rotating portions of the driving motor 29 and the reduction gear 3 全 are all fired on the end side in the width direction of the frame 3, and as a result, during maintenance operation, The operation test will not touch the rotating part, and it can improve the safety during maintenance. According to the structure of the present embodiment, the speed reduction mechanism can be formed between the drive motor 29 and the speed reduction device 30. As a result, a fine reduction ratio that can be engaged with the reduction gear unit 3 can be obtained, and the reduction gear unit 3 can be downsized. In the above embodiment, the passenger conveyor is described as an electric road, and of course, it is also applicable to the escalator. Even in the escalator, if the drive sprocket and the driven sprocket of the pedal direction changing portion are the same as the conventional one, the height of the casing cannot be reduced even if the height dimension of the driving device is reduced. Therefore, in the escalator, the deceleration device and the drive motor are disposed in the same manner as in the above-described embodiment, and the movement trajectory when the pedal direction of the running wheel supported on the upper side of the pedal is pivoted is located at the drive sprocket and the slave. The outer peripheral side of the movable sprocket can reduce the frame of the direction changing portion of the pedal by making the diameters of the driving sprocket and the driven sprocket twice or less the depth dimension of the pedal and more than twice the height dimension of the pedal. The height dimension of the body. [Effect of the Invention] According to the present invention described above, it is possible to obtain a passenger conveyor capable of reducing the height of the casing.
