Is provided.
[0019]
FIG. 4 is an enlarged view showing a partial cross section of the drive mechanism of the pinion gear 90 by the motor 91, and bearing portions 95, provided on the moving frame 82 and the fixing bracket 94 fixed to the moving frame 83. A pinion assembly shaft 99 to which one of the pinion gear 90 and the bevel gear 93 is fixed via bearings 97 and 98 is supported by 96. Therefore, the movement in which the train boarding position indicator is suspended by rotating the pinion gear 90 on the rack 74 according to the rotation angle of the motor 91 corresponding to the moving distance of the train boarding position indicator according to a command from the station operation management unit. The unit 81 can be moved by a predetermined distance.
[0020]
The arrangement structure of the multi-core cable for supplying the moving unit 81 with a motor rotation angle signal corresponding to the moving distance of the moving unit 81 itself, a display signal of the train boarding position indicator, a power source for driving these, etc. 1, FIG. 3, FIG. 5 and FIG. In FIG. 1, reference numeral 101 denotes a connector provided at one end of the unit guide 71, to which a signal from the station operation management unit and a multi-core cable (not shown) for supplying power are connected. Reference numeral 102 denotes a flexible flat cable as a multi-core cable disposed in the unit guide 71 connected to the connector 101. Reference numerals 103 and 104 denote a first fixed pulley and a second fixed pulley provided at both ends of the unit guide 71, respectively. And is rotatably supported by the unit guide 71.
[0021]
Reference numeral 105 denotes a first movable pulley, and 106 denotes a second movable pulley, which are pivotally supported by the traction side plates 107 and 108, respectively. Reference numeral 109 denotes a first wire, and both ends thereof are fixed to the pulling side plates 107 and 108 of the first movable pulley 105 and the second movable pulley 106 via fixed pulleys 103 and 104, respectively. 110 is a second wire, one end is fixed to one end side (first fixed pulley 103 side) of the unit guide 71, and the other end is fixed to the moving unit 81 via the second movable pulley 106. Yes. The flexible flat cable 102 is arranged such that one end thereof is connected to the connector 101 fixed to the other end side (second fixed pulley 104 side) of the unit guide 71, and the other end is connected via the first movable pulley 105. It is fixed to the moving unit 81 and connected to a connector not shown. The first wire 109, the second wire 110, and the flexible flat cable 102 are fixed and connected without slack.
[0022]
As is apparent from the top view (a) and the front view (b) shown in FIG. 5, the first movable pulley 105 around which the flexible flat cable 102 is wound is fixed to the towing side plate 107. A rotating wheel 113 is rotatably attached to the support shaft 111 via a bearing 112. Further, the second movable pulley 106 around which the second wire 110 is wound is, as is apparent from the top view (a) and the front view (b) shown in FIG. A rotating outer ring 118 is provided on a support shaft 114 fixed to the outer ring 118 via a bearing 115, and an inner ring 116 around which the second wire 110 is wound is provided in a wheel of the rotating outer ring 118 via a bearing 117. . Therefore, the inner ring 116 can freely rotate without being affected by the rotation of the rotating outer ring 118. Note that what is described in the left space portion of the unit guide 71 in FIG. 3 is a partial cross-sectional view of the second movable pulley 106 visible through this space portion.
[0023]
The difference in structure is that the height position of the second wire 110 that is hung on the second movable pulley 106 and the height position of the flexible flat cable 102 that is hung on the first movable pulley 105. In order to make the position of the second wire 110 hang around the inner ring 116 with a small outer diameter, and to absorb the unbalance of the rotation of the movable pulleys 105 and 106, The rotating outer ring 118 can be rotated separately. The first movable pulley 105 and the second movable pulley 106 can stably move in the space portion on the side edge of the unit guide 71.
[0024]
The movement of the flexible flat cable 102 on the connection side of the moving unit 81 moves following the movement of the moving unit 81 to the left and right, but the first movable pulley 105 around which the flexible flat cable 102 is wound, The movement of the second movable pulley 106 around which the wire 110 is wound moves by a half of the moving distance of the moving unit 81 according to the principle of the slidable pulley. Therefore, the flexible flat cable 102 and the second wire 110 are moved while maintaining a state in which no slackness occurs even when the moving unit 81 is moved. Therefore, regardless of the position of the movable unit 81 in the movable range, the folded portion of the flexible flat cable 102 moves in accordance with the movement of the first movable pulley 105, so that stable folded movement is possible. become. In addition, by inserting a coil spring, for example, at any location in the pulling (moving) direction of the second wire 110, a slight mechanical error is absorbed, and a tension that is ½ of the coil spring pressure is flexible. The flat cable 102 can be provided.
[0025]
The moving unit 81 is set at a substantially central position between the first movable pulley 105 and the second movable pulley 106 and at a substantially central position between the first movable pulley 105 and the second movable pulley 106. In this state, by setting the distance between the first movable pulley 105 and the second movable pulley 106 to approximately ½ of the distance between the first fixed pulley 103 and the second fixed pulley 104, the moving unit 81 is set as a unit. The guide 71 can be moved to the vicinity of both ends.
In the above-described embodiment of the present invention, the multi-core cable arranged in the unit guide 71 has been described as the flexible flat cable (FFC) 102. However, a normal flat cable, a flexible printed circuit (FPC), or a normal It is also possible to use a round multi-core cable. There are various driving mechanisms for the moving unit 81, such as directly driving the rotational force of the motor 89 that drives the pinion gear 90 of the moving unit 81 via the speed reduction mechanism as described in the conventional example without using the bevel gear 91. It can be made into a mode.
[0026]
