The number of terminals of the terminal block 36 of the pedestrian signal light device 30 with elapsed time is six, and the number of terminals is different. This is because after receiving the display signal from the signal controller with the symbol G or symbol R, the display signal is supplied to the display portions G11, G12 or the display portions R11, R12, and when the symbol G is not illuminated, This is because the display portions G11 and G12 are not lit, and when the pattern R is not lit, the display portions R11 and R12 are not lit. Specifically, in order to supply a display signal to the control board 40 that controls lighting of the display portions G11 and G12 and the display portions R11 and R12, an input signal from G of the connector 33 of the G unit 31 that lights the pattern G After the symbol G lights up, a display signal is output from the GX of the connector 33 (GX of the connector 37 of the cable 35) and displayed on the GX terminal block of the terminal block 39 of the control board 40 via the GX terminal block of the terminal block 36. A display signal is output from the RX of the connector 34 (RX of the connector 38 of the cable 35) after the pattern R is lit by the input signal from the R of the connector 34 of the R unit 32 that lights up the pattern R. A display signal is supplied to the RX terminal block of the terminal block 39 of the control board 40 via the RX terminal block of the terminal block 36 . It should be noted that the reason why the GX terminal block of the terminal block 36 and the RX terminal block of the terminal block 36 are passed through is that the cable 35 can be easily manufactured due to manufacturing problems.

By doing so, a lighting signal for the display portions G11 and G12 or the display portions R11 and R12 is supplied. As a result, the pedestrian signal light device with elapsed time 30 alternately switches and displays the pattern G and the pattern R after installation, and the elapsed time (waiting time is displayed on the display parts R11 and R12, or the remaining time is displayed on the display parts G11 and G12). ) can be displayed.

As described above, the pedestrian signal light device 10 and the pedestrian signal light device with elapsed time 30 are different in the number of terminals of the terminal block provided in the light box and the configuration of the connection destination of the cable. Therefore, when the pedestrian signal light device 10 is changed to the pedestrian signal light device 30 with elapsed time, the terminal block 18 is replaced with the terminal block 36, and processing is performed to add the control board 40 in the light box. In addition, it was necessary to replace each of the pedestrian signal light units. Also, at this time, it was necessary to use the cable 35 for the pedestrian signal light device 30 with elapsed time. Therefore, when changing the pedestrian signal light device 10 to the pedestrian signal light device 30 with elapsed time, it takes a lot of time and effort and cost. If the pedestrian signal light device 10 is entirely replaced with the pedestrian signal light device 30 with elapsed time, the cost will further increase.

(Second embodiment)
The second embodiment differs from the first embodiment in that an elapsed time (waiting time) display is provided only in the G unit that displays permission to pass. In addition, the same code|symbol is attached|subjected to the same structure as 1st Embodiment, and detailed description is abbreviate|omitted about these structures.

FIG. 5 is a diagram for explaining an example of the control configuration of the pedestrian signal light device with elapsed time (hereinafter referred to as "pedestrian signal light device") 200. As shown in FIG.
As shown in FIG. 5, the pedestrian signal light device 200 includes a G unit 101, an R unit 12, and a light box 150 (not shown in FIG. 5), which are pedestrian signal light device units with elapsed time. For convenience of explanation, the front and back surfaces of the G unit 101 and the R unit 12 are shown on the same page as in the first embodiment. Here, the G unit 101 and the cable 114 are the same as the G unit 101 and the cable 114 of the pedestrian signal light device 100 of the first embodiment, and the R unit 12 is the R unit of the pedestrian signal light device 10 of the prior art. Identical to unit 12 .

The G unit 101 displays the walking man pattern G (first display section) in blue light by emitting light from a plurality of blue LED lamps arranged on the back side of the walking man pattern G. Display portions (second display portions) R111 and R112 each including eight rectangular patterns arranged in a line in the longitudinal direction of the drawing are provided on both sides of the walking human-shaped pattern G. As shown in FIG. A plurality of red LED lamps arranged behind the display portions R111 and R112 emit light, so that the G unit 101 displays the waiting time for traffic prohibition in red light color.

On the other hand, the R unit 12 displays the red light color of the walking human-shaped pattern R by emitting light from a plurality of red LED lamps arranged on the back side of the standing human-shaped pattern R. The difference from the first embodiment is that the R unit 12 is not provided with the display sections G11 and G12 for displaying the remaining time of passage permission.

The G unit 101 incorporates a control board 103 for controlling the display portions R111 and R112. A connector 106 provided on the rear surface of the G unit 101 receives a display signal G for controlling display of blue light color, and a connector 107 receives a display signal R for displaying red light color. Also, the connector 14 provided on the rear surface of the R unit 12 receives the display signal R for displaying red light from the terminal block 105 of the G unit 101 via the cable 114 .

The control board 103 of the G unit 101 is provided with an R display detection section 132 and a control section 133 for controlling display/light-out of the red light color of each of the rectangular patterns of the display sections R111 and R112. In this embodiment, since the R unit 12 is not provided with the display portions G11 and G12, it is not necessary to provide a connector for outputting the lighting signal. A connector 104 is provided for controlling display/light-out of the lamp color.

By connecting the connectors 16 and 17 at the terminal ends of the cable 15 to the connectors 106 and 107 of the G unit 101, respectively, the display signal G in blue light color and the display signal R in red light color from the signal controller are sent to the terminals. It can be supplied from the table 18 to the G unit 101 . Further, since the R terminal block of the connector 107 and the R terminal block of the terminal block 105 are connected inside the R unit 101, the red display signal R supplied to the connector 107 of the G unit 101 is transmitted from the connector 107 to the terminal block. It is supplied to the connector 14 of the R unit 12 via the base 105 and the connector 115 of the cable 114 connected to the terminal block 105 .

Here, the display signal RX for starting lighting of the LED lamps of the display portions R111 and R112 is not output from the connector 14 of the R unit 12 . Therefore, by connecting the R terminal block and the RX terminal block of the terminal block 105 of the G unit 101 with an electric wire 201, the display signal RX of the terminal block 105 is supplied. Therefore, it is possible to use the G unit 101 of the first embodiment. Note that the electric wire 201 is not limited to an electric wire, and the R terminal block and the RX terminal block of the terminal block 105 may be connected by means through which electric signals flow, and may be, for example, a metal plate. In addition, assuming that they are connected in advance, a switch that can turn the connection on and off may be provided.

With such a configuration, the pedestrian traffic light device 200 controls the display of the walking human-shaped symbol G and the standing human-shaped symbol R, and displays the standing human-shaped symbol R. In this case, the waiting time can be displayed by controlling the display units R111 and R112.

In the pedestrian signal light device 200 configured as described above, the G unit 101 is a walking human-shaped pattern G, the display portions R111 and R112 for displaying the waiting time, the connectors 106, 107 and 104, and the terminal block. 105, a control board 103, and the R unit 12 has a connector 14 and a standing human figure R, and further has a cable 114 for exchanging each signal between the G unit 101 and the R unit 12. .

Therefore, the conventional pedestrian signal light device (see FIG. 6) 10 can be easily and inexpensively changed to a pedestrian signal light device in which only the G unit 101 has a waiting time display function. More specifically, unlike the conventional pedestrian signal lamp with elapsed time (see FIG. 7) 30, there is no need to replace the pedestrian signal lamp 10 itself, and the G unit 101 displays the elapsed time. Since the pedestrian signal light unit is integrated, the light box, the terminal block 18, the cable 15, etc. of the conventional pedestrian signal light unit 10 can be used, and the G unit 11 can be replaced with the G unit 101. The pedestrian signal light device 10 can be changed to a pedestrian signal light device 200 in which only the G unit 101 of this embodiment has an elapsed time display function.

Further, in the pedestrian signal light device 200, when the G unit 101 displays the walking human-shaped pattern G in blue light color, the display portions R111 and R112 display the waiting time for traffic prohibition. Here, in general, when the symbol R of a standing person is displayed, that is, when the light is red, the demand to know how long it takes for the light to turn green is met when the symbol G of a walking person is displayed. The demand is greater than the desire to know how long it will take to turn red when the light is green. For this reason, considering the cost, there is a need for a pedestrian signal light device in which only the G unit 11 of the conventional pedestrian signal light device 10 is provided with a waiting time (elapsed time) function. The pedestrian traffic light device 200 of this embodiment can satisfy such needs.

In the second embodiment, the G unit 101 displays the waiting time (elapsed time) and the R unit 12 does not display the remaining time (elapsed time). The present invention can also be applied to a configuration in which the unit 101 does not display the waiting time (elapsed time) and the R unit 12 displays the remaining time (elapsed time).
The present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying constituent elements without departing from the scope of the present invention at the implementation stage. Also, various inventions can be formed by appropriate combinations of the plurality of constituent elements disclosed in the above-described embodiments. For example, some components may be deleted from all the components shown in the above embodiments. Furthermore, configurations of different embodiments may be combined.
