Description of the invention [Technical field to which the invention belongs] The present invention relates to a passenger conveyor such as an escalator that generates a step portion between adjacent steps or an electric road without a step portion between adjacent steps. A passenger conveyor capable of reducing the height of the housing. [Prior Art] For example, the passenger conveyor proposed in Patent Document 1 is generally constructed to have a height dimension of the passenger conveyor, particularly a structure that reduces the height dimension of the housing. In other words, the passenger conveyor disclosed in the above-mentioned Patent Document 1 has the reduction gears and the driving motors arranged side by side in a horizontal direction to reduce the height of the entire driving device. [Patent Document 1] Japanese Patent Application Laid-Open No. 58-109375 (Figures 5 and 6) [Summary of the Invention] [Problems to be Solved by the Invention] With the conventional technology described above, the height of the driving device can be reduced. Into. However, even if the height dimension of the driving device is reduced, for example, the driving sprocket and driven sprocket of the pedal direction conversion unit are the same size as the conventional structure, so the height dimension of the passenger conveyor cannot be reduced, especially the frame Body height dimension. It is an object of the present invention to provide a passenger conveyor capable of reducing the height dimension of a frame. [Means for Solving the Problems] In order to achieve the above object, the present invention is to make a depth dimension of a pedal to be less than three times the diameter of a running wheel which is pivotally supported by the pedal, and a gear constituting a driving device is made through a flexible body. The power transmission of the reduction gear and the driving motor is arranged in a plan view, and the power sprocket, gear reduction gear, and driving motor driven by the driving device are arranged along the long axis of the frame of the passenger conveyor. . By arranging the gear reduction device and the driving motor in the above structure toward the long axis direction of the housing in a plan view, the gear reduction device and the driving motor are not arranged in an up-down direction, thereby reducing the number of reductions. As the height dimension of the driving device. By transmitting power through the flexible body to the gear reduction device and the driving motor in the above structure, even if the center of the input shaft of the gear reduction device and the center of the output shaft of the driving motor are offset, the gear reduction device and the The other side of the driving motor is arranged in a height range on one side. Accordingly, the height dimension of the driving device is determined by the higher height dimension of the gear reduction device and the driving motor, and the height dimension of the housing does not increase due to the addition of the height dimensions of the two. In addition, by making the depth dimension of the pedal in the above structure less than three times the diameter of the running wheel which is supported by the pedal, 'even if the driving sprocket or driven sprocket is made to a small diameter, the direction is changed. Even if it does not interfere with the adjacent pedal, the height dimension of the pedal direction switching section can be reduced as a result. Therefore, the height of the drive unit determining the height of the frame is reduced. (6) (3) (3) 200426103 The height of the frame and the pedal direction conversion unit can be reduced. Therefore, the height of the frame can be reduced. A first embodiment of the present invention will be described with reference to the electric road shown in FIGS. 1 to 3. The electric road 2 installed on the ground 1 is a base in which a frame 3 housed in a recess 1P formed in the ground 1 is formed. The frame body 3 is provided at both ends in the long axis direction with lifting platforms 4A and 4B, which are on the same plane as the above-mentioned ground surface 1. The driving sprocket 5 and the driven shaft are supported below the lifting platforms 4A and 4B. Sprockets 6. The drive sprocket 5 includes a pair of drive sprocket wheels 5 A and 5 B fixed on the drive shaft 7 at intervals. Similarly, a pair of the driven sprocket wheels 6 are fixed to the rotation shaft 6 S. The drive shaft 7 and the rotation shaft 6 S are rotatably supported on the frame 3 via bearings 8A and 8B, respectively. Between the pair of driving sprocket wheels 5A, 5B and the pair of driven sprocket wheels 6, a pair of recirculating pedal chains 9 are wound, and a plurality of pedals 10 are connected to the pair of pedal chains. 9. As shown in FIG. 2, the pedal 10 is axially supported by the running wheel Π at a fixed position on one side in the depth direction, and is protruded toward the adjacent pedal side at the other end in the depth direction for holding. Bearings 12 of the running wheels of the adjoining pedals. The bearing 12 has a recessed groove parallel to the depth of the pedal and opened on the side adjacent to the pedal, and (4) (4) 200426103 of the running wheel adjacent to the pedal is engaged with and slides in the recessed groove. The running wheel 11 is prepared as follows: It is guided on a guide rail (not shown) laid in the frame 3, and once moves between the two lifting platforms 4A and 4B. The depth dimension L of the pedal 10 is a length that is three times or less the diameter Dr of the running wheel 11. In addition, by making the depth L of the pedal 10 into three times or less the diameter Dr of the running wheel 11, the diameter Ds of the driving sprocket 7 and the driven sprocket 6 can be formed as follows: The depth dimension L is less than twice, and the height dimension L is more than twice. A railing portion 13 is erected along the moving direction of the pedal 10 on the frame 3 facing the both sides of the pedal 10, and the peripheral portion of the railing portion 13 guides the movable armrest 14 to be movable. . The moving armrest 14 is driven below the railing portion 13 by a hand drive device 15 to move in the same direction at a speed synchronized with the pedal 10. The armrest driving device 15 is configured to hold the front and back surfaces of the movable armrest 14 by a driving roller 16 and a driven roller 17. The sprocket 18 is fixed coaxially with the driving roller 16, and by rotating the sprocket 18, the driving roller 16 is rotated so as to be pressed toward the driven roller 17 side to drive the movement Handrail 14. A sprocket 18 is obtained by driving power from the drive shaft 7 to drive the drive roller 16. That is, the power sprocket 17 for handrail driving provided between the drive sprocket wheels 5A and 5B of the drive shaft 7 is provided on the side closer to the handrail drive 15 than the drive shaft 7 is supported by the handrail. Intermediate sprocket 2 1 of the intermediate shaft 2 0, a connecting chain 22 wound around the power sprocket 19 and the intermediate sprocket 21, and two -8- (5) (5) 200426103 provided on the intermediate shaft 20 A pair of armrest drive sprocket wheels 23A, 23B at the end, and a drive chain 25 wound between the armrest drive sprocket wheels 23A, 23B and the sprocket 18 of the drive roller 16 via a plurality of guide sprocket wheels 24, The power of the drive shaft 7 is transmitted to the armrest driving device I5. On the other hand, the means for applying power to the drive shaft 7 includes a power sprocket 26 fixed to a shaft end side closer to the drive sprocket 5 B, a drive device 27, and a power sprocket. The power transmission chain 28 of the power between 26 and the driving device 2 7. The drive device 27 includes, for example, a drive motor 29 such as an induction motor, and a reduction gear 30. This structure is fixed to the housing 3 via a common base 31. The drive motor 29 and the reduction gear 30 are arranged along the long axis of the housing 3 in a plan view. The drive motor 29 is provided with a flywheel 3 2 and a small pulley 33 on a rotating shaft. 30 includes an input pulley 34 and an output pulley 35. Between the small pulley 33 of the drive motor 29 and the input pulley 34 of the reduction gear 30, for example, a 3 to 4 series of V-belts 36 is wound, and the power is wound around the power sprocket 26 The transmission chain 28 is wound around the output sprocket 35 of the reduction gear 30 and transmits the power of the drive motor 29 to the drive shaft 7 to drive the pedal 10 and the movable armrest 14. The method of transmitting the power of the driving motor 29 to the reduction gear 30 is not limited to this, although the small pulley 3 3, the input pulley 34, and the V-belt 36 are used, for example, a power transmission flexible body may be used. Chains or belts with teeth, and use sprocket or pulley around them. A control device 37 for controlling the operation of the electric road 2 is built into the space in the frame 3 provided with the driving device 27. According to this embodiment, since the drive motor 29 and the reduction gear 30 of the drive device 27 are arranged along the long axis direction of the housing 3 so as not to overlap in a plan view, the drive device 27 can be reduced. The height dimension of the frame 3 can be reduced. The conventional structure 'also has a structure in which the drive motor 29 and the reduction gear 30 do not overlap, and the rotation shaft of the drive motor 29 is connected to or integrated with the input shaft of the reduction gear 30 in a plan view. However, 'the driving motor 29 or the reduction gear 30 described above has a large difference in the position of the rotation axis or the input shaft in the height direction due to the capacity or shape'. Therefore, when the shafts are connected or integrated, the drive will be driven. The height dimension of the device 27 is increased. That is, in FIG. 1, when the input shaft (the input pulley 34) of the reduction gear 30 is connected to or integrated with the reduction shaft 30 having a lower height than the rotation shaft (33 small pulleys) of the drive motor 29, the drive motor is driven. The appendage of 29, that is, the flywheel 32 is a flywheel 32S positioned as shown by a two-dotted dotted line, and projects below the frame 3. In order to eliminate this protrusion, in addition to supporting the drive motor 29 and the reduction gear 30 in separate bases, they must also be fixed in the frame 3, which will cause the drive device 27 to be installed in the frame 3. To complicate, it requires complicated production. Therefore, as in this embodiment, in addition to making the driving motor 29 and the reduction gear 30 not overlapped in a plan view, it is also important to transmit power by a flexible body. In addition, since the small pulley 33 of the drive motor 29 and the input pulley 34 and output sprocket 35 of the reduction gear 30 are directed toward the power sprocket 26, -10- (7) (7) 200426103 is on the top The flexible body is the power transmission chain 2 8 and the V-belt 3 6 ′. Therefore, the rotating parts of the driving motor 29 and the reduction gear 30 are all located on the width end portion side of the frame 3. As a result, during maintenance operation , The operator will not touch the rotating part, which can improve the safety during maintenance. With the structure of this embodiment, a reduction mechanism can be formed between the drive motor 29 and the reduction device 30. As a result, a fine reduction ratio that can be matched with the reduction device 30 can be obtained, and the reduction device 30 can be miniaturized. In the above-mentioned embodiment, although the passenger conveyor is described using electric roads, it is of course applicable to escalators. Even if the driving sprocket and driven sprocket of the escalator, pedal direction changing section are the same as the conventional method, the height of the housing cannot be reduced even if the height of the driving device is reduced. Therefore, in the escalator, similar to the above-mentioned embodiment, a reduction gear and a driving motor are arranged, and the movement trajectory when the pedal direction of the running wheel supported by the upper side of the pedal is pivoted is located between the driving sprocket and the slave By making the diameters of the driving sprocket and driven sprocket less than twice the depth dimension of the pedal and more than twice the height dimension of the pedal, the frame of the direction changing part of the pedal can be reduced. Body height dimension. [Effects of the Invention] According to the present invention described above, a passenger conveyor capable of reducing the height of the housing can be obtained.
