Claims

[Scope of utility model registration request]

a memory circuit that stores the states of a left input and a right input of a turn signal of a vehicle such as an automobile or a motorcycle, and outputs only one of the left output and the right output when only one of the left input and the right input is input;
an input off detection circuit that resets the contents of the memory circuit when it detects that the left input and the right input are both off; and a memory state of the memory circuit when it detects that both the left input and the right input are input. and a second detection circuit that resets the memory state of the memory circuit when it detects that both the left output and the right output are output from the memory circuit. circuit.
