- a predetermined periodic signal is output from the control unit 25 to the neutral position detection unit 40, and the neutral position detection unit 40 outputs a neutral position signal N1 synchronized with the predetermined periodic signal to the position detection unit 30, so that the position signal is As a voltage signal having no periodicity, the neutral position signal N1 is superimposed on the position signal and output to the control unit.
- the control unit 25 can reliably determine that the movable body 13 is in the neutral position if the signal input from the neutral position detection unit 40 is a predetermined periodic signal.
- the position signal has no periodicity, for example, a substantially constant voltage signal, it can be more reliably determined from the voltage that the movable body 13 is moving in any direction, not in the neutral position. Therefore, the discrimination of the signal becomes easier and the operation direction can be detected more reliably.
- the control unit 25 outputs a predetermined periodic signal to the neutral position detecting unit 40, and the neutral position detecting unit 40 is synchronized with the predetermined periodic signal.
- the signal is output to the position detector 30.
- control unit 25 can more reliably detect whether the neutral position is reached.
- the neutral position detection unit 40 includes the light emitting / receiving element 19, and is neutralized by the output from the light emitting / receiving element 19 by the vertical movement of the arm portion 17 ⁇ / b> A accompanying the vertical movement of the moderation member 17. It is the structure which detects a position.
- a magnet instead of the light emitting / receiving element 19 and the arm portion 17A, a magnet may be fixed to the arm portion 17A of the moderation member 17 and a magnetic detection element such as a Hall element may be disposed so as to face the magnet.
- the present invention can be implemented even if the neutral position is detected by the output from the magnetic detection element accompanying the vertical movement of the arm.
- a push switch or a lever switch is arranged below the arm portion 17A, and the arm portion 17A moves up and down as the moderation member 17 moves up and down.
- the neutral position signal N1 may be output by turning ON / OFF the switch.
- the multidirectional input device 26 shown in FIG. 1A is configured by a multidirectional input unit 22 and a control unit 25 of an electronic circuit or electronic device in the vehicle connected to the multidirectional input unit 22.
- the multidirectional input unit 22 includes the control unit 15 so that the neutral position detection and the moving direction detection of the movable body 13 can be performed by the multidirectional input device 26. Good.
- the arm portion 17A extends from the moderation member 17, but does not necessarily have to be extended.
- the arm portion 17A may be integrally formed with the moderation member 17 or may not extend.
- the neutral position detector 40 uses the light emitting / receiving element 19 arranged so that the light emitting part and the light receiving part face each other.
- a light emitting / receiving element in which the light emitting part and the light receiving part are arranged next to each other may be used.
- the arm part 17A functions as a reflection part.
- the multi-directional input device of the present disclosure can be realized with a simple configuration and capable of various and reliable operations. It is useful mainly for the operation of various electronic devices in automobiles.
