2. Description of the Related Art When a vehicle is temporarily stopped on a road shoulder or the like, a hazard signal is operated to alert other vehicles to blink turn signal lamps all at once. And
When starting the vehicle from this stopped state, operate the turn signal switch to one side to flash only the turn signal lamp on one side, but if you do not turn off the hazard switch at that time, turn the turn signal switch to one side. Even if it is operated to, the turn signal lamps on both sides are still flashing hazard, and it is not possible to inform other vehicles that the vehicle is starting. Therefore, conventionally, a technique has been proposed in which the hazard operation is automatically canceled when the turn signal switch is operated. For example, Japanese Utility Model Laid-Open No. 4-135844 discloses a technique for automatically releasing the hazard operation when the turn signal switch is operated to start the vehicle while the turn signal lamp is operating the hazard. It was More specifically, the related art is a NAND gate, an inverter, a transistor,
It has a pulse generation circuit configured by combining a large number of electronic elements such as a diode, a resistor and a capacitor, a hazard output circuit configured by combining a large number of electronic elements like the pulse generation circuit, and the like. The pulse generation circuit outputs a reset pulse signal to release the hazard operation when the turn signal switch is turned on when the turn signal lamp is in hazard operation and the ignition switch is in the on operation state. Had. Further, the hazard output circuit has a function of receiving a signal from the hazard switch to be in a hazard operating state, and also having a function of receiving a reset pulse signal from the pulse generating circuit to cancel the hazard operating state.

However, in the above-mentioned prior art, since a large number of electronic elements are combined to form a circuit, there are many points to be managed in order to ensure reliability, and malfunction occurs due to radio wave interference or the like. Since the circuit configuration uses an easy electronic element, an extra circuit configuration such as a noise filter and a regulator is required. Further, the above-mentioned conventional technology is
It is necessary to construct an electric circuit that is separate from the turn signal circuit and the hazard circuit that are generally adopted in existing vehicles, and it is necessary to set a dedicated electric circuit that adopts the conventional technique from the design stage of the vehicle. In other words, it is difficult for the conventional technology to additionally install the turn signal priority hazard device as a general-purpose product on an existing vehicle. Further, in the above-mentioned conventional technique, not only it is necessary to connect a plurality of diodes D10, D13, D14, D15, D16 in the electric path leading to the turn signal lamp, but also the rush current generated when the turn signal lamp is lit. It was necessary to employ an expensive diode for large current so that the diode would not be destroyed by a large current (rush current).

The present invention solves the above-mentioned problems, does not require a large number of electronic elements, and therefore there are few management points for ensuring reliability, and there is a risk of malfunction due to radio interference. The purpose of the present invention is to provide a turn signal priority hazard device that is easy to be additionally installed in an existing vehicle as a general-purpose product.
