  The comb 8 is made of a translucent resin. Regarding the light transmission performance of the resin that forms the comb 8, the light transmission performance is such that the light emitted from the EL sheet that is disposed below the comb 8 and serves as a light source can be viewed from the upper surface side of the comb 8 as described later. The light transmission performance is preferably as high as possible.

  An EL (Electroluminescence) sheet 11, which is a thin plate light source, is interposed in an overlapping portion between the comb plate 7 and the comb 8. The EL sheet 11 is fastened and fixed to the comb plate 7 together with the comb 8 by a countersunk screw 9. The EL sheet 11 emits light when an AC voltage is applied.

  The EL sheet 11 is connected to a control unit 12 which is a brightness varying unit that varies the brightness of the EL sheet 11. The control unit 12 is connected to the EL sheet 11 via the signal line 13, and the control unit 12 is connected to the AC power source 14.

  The control unit 12 includes a ROM that stores programs and fixed data, a RAM that temporarily stores signals from various sensors, and a CPU that performs various calculations according to the programs stored in the ROM using signals input to the RAM. And. Further, the control unit 12 has a function as an inverter, and performs control to receive signals from various sensors, vary the frequency, and vary the power output to the EL sheet 11. One of the controls performed by the control unit 12 is the brightness of the EL sheet 11 when there is no user according to the detection result from the detection means for detecting the presence or absence of the user who uses the escalator than when there is a user. There is control to lower. Further, as one of the other controls performed by the control unit 12, a control for repeatedly raising and lowering the luminance of the EL sheet 11 according to a detection result from a detection unit that detects that an escalator user has approached the entrance / exit 6. There is.

  In such a configuration, when an AC voltage is applied to the EL sheet 11 and the EL sheet 11 emits light, the light emitted from the EL sheet 11 passes through the comb 8 formed of a translucent resin, and the transmitted light is transmitted. Radiated from the upper surface of the comb 8. The light emitted from the upper surface of the comb 8 is visually recognized by the user of the escalator. Thereby, by emitting light from the upper surface of the comb 8, it is possible to clearly notify the position of the boundary between the comb 8 and the step 2 to the user of the escalator. It is possible to prevent an accident that occurs because the user is not aware of the position or misidentifies the position.

  The EL sheet 11 can be attached by interposing the EL sheet 11 between the comb plate 7 and the comb 8 and fastening the EL sheet 11 together with the comb 8 with a countersunk screw 9. For this reason, the mounting structure of the EL sheet 11 can be made extremely simple. Furthermore, even when the EL sheet 11 is retrofitted to an existing escalator, a large-scale repair work is unnecessary, and the retrofitting work can be performed easily and inexpensively.

  Further, by interposing the EL sheet 11 between the comb plate 7 and the comb 8, it is possible to prevent the EL sheet 11 from being stepped directly on by the user, and to improve the durability of the EL sheet 11. be able to.

  Regarding the lighting control of the EL sheet 11, the luminance of the EL sheet 11 can be varied. For example, the voltage to be applied when there is a user according to the detection result from the detection means for detecting the presence or absence of the user. The luminance can be increased by increasing the luminance, and when there is no user, the luminance can be decreased by decreasing the applied voltage. Thereby, the position of the boundary between the comb 8 and the step 2 can be clearly notified to the user, and power consumption can be reduced and the life of the EL sheet 11 can be increased.

  Further, regarding the lighting control of the EL sheet 11, the voltage to be applied is raised and lowered according to the detection result from the detection means for detecting that the user has approached the entrance / exit 6, and the increase and decrease of the luminance of the EL sheet 11 is repeated. Can do. Thereby, the position of the boundary between the comb 8 and the step 2 can be more clearly notified to the user.
