[0025]
It is desirable that the battery 1, the light lighting detection unit 8, the oscillation circuit unit 12, and the light emitting units 21 and 22 are appropriately molded with resin. Thus, if the flashing device 37 part is molded with resin, it will not be affected by rainwater even if installed in an outdoor parking lot, and it will not be affected by condensation in an underground parking lot, The durability of the entire flashing device 37 is improved.

On the circuit board 45, the battery 1, the darkness detection sensor 3, the light lighting detection sensor 9, and the light emitting means 21, 22 are provided. It is provided with circuit components that operate them.
[0028]
The light emitting means 21 and 22 and the light lighting detection sensor 9 face the inside of the plastic cover 43, and the darkness detection sensor 3 is another transparent or translucent cover provided on the back side of the flange 37b. Facing inside (not shown).
[0029]
Next, the operation will be described. First, in a time zone in which the outdoor is bright like daytime, or in a time zone in which outdoor light is used as auxiliary light like an underground parking lot, the darkness detection sensor 3 detects the external light and is turned on. Therefore, the capacitor 4 is charged, and the potential of the other input terminal of each NOR gate 13, 14 becomes high level “1”. At this time, the oscillation circuit unit 12 does not oscillate.
[0030]
On the other hand, when the surrounding environment of the parking lot becomes dark or the dark indoor parking lot exceeds the set level, the darkness detection sensor 3 operates to be turned off.
[0031]
Therefore, the charging voltage of the capacitor 4 is discharged through the resistor 5, and the potential of the other input terminal of each NOR gate 13, 14 becomes low level “0”. In this state, as in the daytime, the operation of the oscillation circuit unit 12 is not started.
[0032]
On the other hand, when the vehicle enters the parking lot with light on in such a dark time period and tries to park at a predetermined parking position, the light of any one of the lights such as the headlight and taillight is The light lighting detection sensor 9 installed in the car stop main body 31 is irradiated.
[0033]
For this reason, one input terminal potential of the NOR gate 13 becomes low level “0”, and the output of the NOR gate 13 becomes high level “1” for the first time, and this is input to one input terminal of the NOR gate 14 in the next stage.
[0034]
For this reason, the output of the NOR gate 14 becomes a low level “0”, which is input to the one input terminal of the NOR gate 13, so that the operation of the NOR gate 13 is inverted and the output is inverted to a low level “0”. To do.
[0035]
Accordingly, the output of the NOR gate 14 at the next stage is inverted to the high level “1”, and the outputs of the NOR gates 13 and 14 are alternately operated at the timing (cycle) determined by the timing capacitor 15 and the resistors 17 and 19. Is inverted and the oscillation operation is continued.
[0036]
The oscillation output is applied to the field effect transistor 23 from the output terminal of the NOR gate 13, and the light emitting means (photodiodes) 21 and 22 blink at the timing by the ON / OFF operation according to the timing.
[0037]
As a result, in parking operation at night or the like, the pair of light emitting display portions 20 provided on the left and right sides of the car stopper main body 31 blinks to accurately display the position of the car stopper main body 31 at the parking position. Therefore, the driver can orderly park the vehicle at a predetermined position using this as a mark.
[0038]
In the present invention, the battery 1 consumes power because the darkness detection sensor 3, the light lighting detection sensor 9, and the field effect transistor 23 as a switch means are turned on, and the light emitting means 21 and 22 are lit. Since this is only a case, not only the power consumption of the sensors 3 and 9 and the field effect transistor 23 but also the large power consumption by the light emitting means 21 and 22 connected in series to the field effect transistor 23 can be effectively reduced. It becomes.
[0039]
Further, the darkness detection sensor 3 is disposed on the opposite side of the light lighting detection sensor 9 from the battery 1 and other light shielding plates (not shown), so that the darkness detection is performed by the light of the vehicle to be parked. It is possible to sufficiently avoid malfunction of the sensor 3.
[0040]
