It is attached inside the body 10 at 20. On the other hand, the print 14 on which a part of the EE switch circuit 11 connected to the circuit of the printed circuit board 13 by the lead wire 21 and the control circuit of the timer circuit 12 and the like are mounted is attached with a screw 20 in the same manner as the printed circuit board 13. 'Is attached inside the body 10. The printed circuit board 15 on which a part of the EE switch circuit 11 connected to the circuit of the printed circuit board 13 by the lead wire 22 is mounted is attached to the back plate 16.

A lamp load L and a terminal block 23 for connecting an AC power source with a terminal screw 23 a are arranged on the outside of the back plate 16, and the terminal block 23 has a window hole 24 opened in the back plate 16. It is connected to the circuit of the printed circuit board 15 through a lead wire 21 ', and is attached to the back plate 16 with a mounting screw 25 so as to sandwich the back plate 16 with the printed circuit board 15. The back plate 16 is fixed to the body 10 with mounting screws 26.

One half of the surface of the body 10 is one step lower than the surface of the other half, and the lighting surface 28 of the photo sensor 27 of the EE switch circuit 11 is provided on the higher surface and the above setting is made on the lower surface. An opening window 29 for exposing the time display portion 19 as shown in FIG. 1, holes 30a, 30b for exposing and inserting the pushbuttons 18a, 18b of the pushbutton switches 17a, 17b, and the operation mode of the automatic blinker are set and switched. A window 32 for exposing the operation portion 31a of the slide switch 31 is provided, and this exposed lower surface is covered by an opening / closing door 33 that is pivotally supported on the body 10 so as to be openable and closable. It is being hidden. The open / close door 33 is made of a light-transmissive (transparent) resin. One side is a pivot portion, and the other side portion is engageable / disengageable with a locking hole 34 provided on the side surface of the body 10. A pawl 35 is provided. Further, in order to close the opening / closing door 33 in a watertight manner, a waterproof packing 36 (shown by hatching in FIG. 2) which is in close contact with the peripheral edge of the opening / closing door 33 is arranged around the exposed surface. As shown in FIG. 4, ventilation holes 37 are provided in the side surface of the body 10 and the waterproof packing 36.

When the automatic blinker configured as described above is mounted on the wall surface, the body 10 is provided with the waterproof rubber 39 having the opening 38 corresponding to the terminal block 23 interposed between the wall 10 and the wall surface. It is fixed to the wall surface by a mounting screw (not shown) which is inserted through the mounting hole 40a of the mounting tab 40 which is integrally provided with the mounting hole 40a and the mounting hole 41a of the tab 41 which is provided in the waterproof rubber 39.

In FIG. 2, 42 is a push-up spring of the push buttons 18a and 18b, 43 is a lead wire for connecting the slide switch 31 to the circuit, and 44 is a lead wire for connecting the photo sensor 27 and the EE circuit 11. When using the automatic blinker of the present invention constructed as described above, first, the operation mode is set by the slide switch 31. That is, when the operation portion 31a of the slide switch 31 is moved to the left end in FIG. 1, the normal mode is set. In this normal mode, the level of the external light received by the photo sensor 27 decreases from a certain level to a certain level again. During this period, the EE switch circuit 11 is turned on to light the lamp load L. When the operation portion 31b is moved to the right end, the light-off time setting mode is set. In this case, the timer circuit 12 measures the set time and outputs a signal to the EE switch circuit 11 to stop the energization of the lamp load L, Forcibly turn off the lamp load L. This extinguished state is maintained until the light receiving level of the photo sensor 27 of the EE switch circuit 11 exceeds a certain level, and thereafter, the operation of the EE switch circuit 11 takes precedence until the timer circuit 12 measures the set time again and outputs a signal. To be done. When the operating portion 31a of the slide switch 31 is moved to the center, the time setting mode is set. In this state, by pressing the push buttons 18a, 18a, the hour and minute of the set time can be changed respectively, and the set time is set. It can be confirmed on the time display section 19. In this way, the set time can be changed and corrected at any time simply by operating the push buttons 18a, 18a.

Since the set time and the set state of the operation mode can be confirmed from the outside through the light-transmissive opening / closing door 33 even when the opening / closing door 33 is closed, the opening / closing operation is performed one by one when checking only. It is not necessary to open the door 33. By the way, in the above-mentioned embodiment, the light-off type automatic blinker is used. However, as shown in FIG. The present invention may be applied to. In this case, the timer circuit 12 gives a signal to the dimming circuit 50 when the set time is measured, and from this point on, the dimming circuit 50 limits the lamp current of the lamp load L to dimm it. This dimmed state is maintained until the light receiving level of the photo sensor 27 of the EE switch circuit 11 exceeds a certain level, and thereafter the operation of the EE switch circuit 11 is continued until the timer circuit 12 measures the set time again and outputs a signal. have priority.
