  ADVANTAGE OF THE INVENTION According to this invention, the switch apparatus comprised more functionally while achieving the misoperation prevention of a switch can be obtained.

  Hereinafter, specific examples of the present invention will be described in detail with reference to the drawings. The electronic apparatus shown in FIGS. 1 to 3 is a radio wave correction type alarm clock 1 that receives a standard time radio wave and corrects the time. The radio-controlled alarm clock 1 is provided with a time display unit 20 on the front surface of the case body 10, a movement 30 is disposed at the rear of the time display unit 20, and an hour hand 31 connected to the movement 30 via a pointer pipe 30 a. The minute hand 32, the second hand 33, and the reference hand 34 are configured to rotate in the time display unit 20. Further, inside the case body 10, a control means 40 storing a required program and a receiving means 50 for receiving standard time radio waves are provided. The control means 40 corrects the count time based on the standard time radio wave received by the receiving means 50, and controls the movement 30 according to the count time. That is, the exact time counted by the control means 40 is displayed by the hour hand 31, the minute hand 32, and the second hand 33. The reference hand 34 displays the generation time of the wake-up signal. When the position of the reference hand 34 output from the movement 30 coincides with the count time, the control means 40 generates a notification sound as a wake-up signal from a speaker (not shown). Incidentally, 60 in the figure is a light emitting means for illuminating the time display unit 20. The light emitting means 60 is turned on when the alarm signal is generated. The light emitting means 60 may be configured such that a light sensor is provided at a key point of the case body 10 so that the light is turned on when the area becomes dark. The operation of the radio wave correction type alarm clock 1 is performed by a control unit 70 provided on the back surface of the case body 10. The control unit 70 is configured by arranging various switches and needle alignment for rotating the reference needle 34. The various switches are connected to the control means 40.

As shown in FIG. 4, the control unit 70 includes a ring stop switch 200 for selecting generation and stop of an alarm signal, an alarm signal generation switch 300 for arbitrarily generating an alarm signal, and a standard time radio wave. A reception status confirmation switch 400 for arbitrarily confirming the reception status is provided. The wake-up signal is generated when the sound stop switch is ON, and is not generated when it is OFF. The reception status confirmation switch 400 of this example is a switch for generating a predetermined confirmation sound from the speaker or pressing the light emitting means 60 in a predetermined pattern when pressed. The reception status of the standard time radio wave can be confirmed by a confirmation sound or a lighting pattern of the light emitting means 60. Description of other switches is omitted.
In the case of this example, the alarm signal generation switch 300 and the reception status confirmation switch 400 are not required to be operated according to ON / OFF of the ring stop switch 200 or should be prevented from being operated due to control. It has become. For example, since the alarm signal is not generated even if the alarm signal generation switch 300 is operated when the sound stop switch 200 is OFF, the user may misunderstand this as a failure. Therefore, in this example, in order to prevent an erroneous operation of the alarm signal generation switch 300 and the reception status confirmation switch 400, a switch device 100 is provided that associates the ring stop switch 200, the alarm signal generation switch 300, and the reception status confirmation switch 400 with each other.
