Further, the reception display device based on the above-mentioned reception display method has reception judgment means for judging the reception state as described above, and the drive control means changes the step hand operation state of the second hand based on the judged reception state. It is something to switch.
At this time, in the case of non-reception, the second hand is set once every two seconds so that it can be recognized at a glance, for example, differently from normal hand movement.
When the reception is completed, the reception is completed by moving the hand in steps, and the completion of the reception is indicated by moving the second hand one step at a time once per second. Then, the state shifts to the normal hand operation state.

Next, a description will be given of a method and operation of receiving and displaying in the radio-controlled timepiece having the above-described configuration. In the above functional configuration, when the receiving unit 54 starts receiving, the receiving determining unit 58 determines that the receiving is being performed from the receiving state at that time, and controls the driving of the pointer driving unit 52 by the non-receiving hand moving unit 50. Thus, the second hand is driven once every two seconds, two steps at a time. Note that, even when the hand movement state of the second hand is different from normal, the time display displayed by the second hand does not change, and only the hand movement state changes. From such movement of the second hand, the user can easily determine that the reception has not been completed yet.

Thereafter, when the receiving means 54 completes the reception, the reception discriminating means 58 determines that the reception is completed based on the reception state at that time, and drives the pointer driving means 52 to the normal hand driving means 48 in place of the non-received hand driving means 50. Control. As a result, the second hand is driven once per second, one step at a time. As described above, when the second hand is in the normal hand movement state, the user can easily recognize that the reception has been completed.

On the other hand, if the reception is not bureaucratic after a certain period of time has elapsed since the start of the reception, the reception determining means 5
Reference numeral 8 determines that reception is not possible, continues unusual hand movement drive control by the non-reception hand movement means 50, and indicates that reception is not possible. As a result, the user recognizes that it is not possible to receive radio waves, and moves the watch to a position where it can receive, or performs the receiving operation again, and work to return to the normal hand movement state indicating completion of reception become.

Receiving a radio wave as described above and correcting the time based on the time information obtained at that time can be performed not only when the battery is replaced or when the reset switch is operated, but also several times a day. It is done on a regular basis. That is, as shown in FIG. 3, when there is a receiving instruction from the automatic receiving instruction means 60 at regular intervals, the receiving means 54 starts receiving. If the second hand moves abnormally as described above during such automatic reception, the operation state of the second hand changes suddenly, so there is a possibility that the user will mistake the battery life warning or failure. The reception state is determined and the operation state of the second hand is changed only when an external switch for forcibly performing reception is operated without determining the reception state.

That is, an external switch 62 for forcibly receiving the signal by the receiving means 54 and a switch operation determining means 64 for determining whether or not the switch has been operated are provided. The switch operation determining means 64 determines that the switch operation has been performed. When receiving, the receiving means 54 starts receiving, and at this time, the receiving determining means 58 determines the receiving state and switches the hand operating state of the second hand. As described above, since the operation state of the second hand changes only when the external switch 62 is operated, it is possible to prevent the reception display from being erroneously recognized as another alarm or the like. When the switch operation determining means 64 determines that a switch operation has been performed, the unreceived hand moving means 50 may control the driving of the second hand.

Further, as shown in FIG.
8 is determined to be unreceivable, and when the hand movement different from the normal operation is continued by the non-reception hand movement means 50, the predetermined time elapses or the operation of the external switch for normal hand operation causes the operation of the non-reception hand movement means 50. Operation change means 66 for changing the drive control by the normal hand operation means 48 to the drive control by
Is provided. The hand movement changing means 66 controls the second hand to be driven by the non-reception hand movement means 50 for a certain period of time or until an external switch is operated when the reception discriminating means 58 determines that the signal is being received or cannot be received. Thereafter, when a predetermined time has elapsed or when an external switch is operated, the driving control of the second hand by the normal hand moving means 48 is changed to the driving control of the second hand by the non-receiving hand moving means 50. This allows
After the user recognizes that the reception is not possible, the display can be set in a normal hand operation state so that the display does not cause a sense of incongruity.

3. Receiving means for receiving radio waves to obtain time information, correction control means for instructing correction of a displayed time based on the time information obtained by the receiving means, and a hand drive for driving a second hand, a minute hand and an hour hand. Means for controlling the operation of the pointer driving means, and driving control means for controlling the driving of the pointer driving means based on an instruction from the correction control means to correct the display time. The reception means includes reception determination means for determining whether the reception state of the reception means is reception, reception disabled, or reception completion. When the reception determination means determines that reception is being performed or reception is not possible, the drive control means sets the pointer The second hand is caused to move stepwise at an interval different from normal to the driving means to indicate that no reception has been performed.If the reception determining means determines that reception has been completed, the driving control means causes the pointer driving means to transmit the second hand to the pointer driving means. A reception display device for a radio-controlled watch, characterized in that the second hand is moved stepwise at regular intervals to display the completion of reception.
