The date will be displayed.

The alarm time storage circuit 32 loses the stored alarm time data to the coincidence detection circuit 29 and the display switching circuit 28, and the alarm time data returned to the limb detection circuit 29 is given from the time counting circuit 27. When the time data matches the time data, a match detection circuit 29 outputs a match signal to the buzzer drive circuit 34, and the speaker 35 emits an alarm sound. Furthermore, the alarm time data given to the display switching circuit 28 is transmitted by the mode switching from the motor drive circuit 30 when the digital clock section 3 is pulled out one step from the digital storage section 4b25'1 as shown in FIG. 2(B). When the display switching circuit 28 switches to alarm display according to the signal, the alarm time is displayed on the liquid crystal display 2ml5. Moreover, in this state, when the select switch 22a and set switch 22b of the key switch unit 22 are operated, a digit select signal and a +1 set signal are output from the input control unit 31 to the alarm time storage circuit 32, and based on these signals, The stored alarm time is corrected in the alarm time storage circuit 32, and the corrected alarm time data is displayed on the liquid crystal display device 15 via the display switching circuit 28.

On the other hand, when the correction switch 22c of the key switch section 22 is pressed, the display switching circuit 28 enters the time correction mode by the time correction mode signal from the input control section 31, and the current time, month, day, day of the week, etc. are displayed on the liquid crystal display device 15. Data is displayed. When the select switch 22a and the set switch 22b of the key switch section 22 are operated, a digit select signal and a +1 set signal are applied from the input control section 31 to the time counting circuit 27, allowing the time to be corrected. That is, in this state, the select switch 22
When the set switch a and the set switch 22b are operated, the time data such as the current time, month and day, and day of the week of the time counting circuit 27 is corrected based on the digit select signal and +1 set signal from the input control unit 31, and the corrected Time data is displayed on the liquid crystal display device 15 via the display switching circuit 28.

After adjusting the time, press the correction switch 22c again to switch to the stopwatch mode, and if the digital clock section 3 is stored in the digital storage section 4b in this state, the 1 display + JJ switching circuit 28 will switch to the date/day of the week mode. The date and day of the week are displayed on the liquid crystal display device 15.

However, according to the electric clock configured as described in -1-, the digital clock part 3 is stored in the digital storage part 4b of the watch case 4 so that it can appear and retract. By changing the appearance (face), external shape, design, etc., it is possible to provide an electronic wristwatch with a new image that has never existed before. In particular, when the digital watch section 3 is stored in the digital storage section 4b of the watch case 4, only a part of the digital watch section 3 is exposed through the lower right opening 4d of the watch case 4. Digital time 1:1 The exposed part of part 3 becomes smaller, giving it a high-class feel as a combination watch.Moreover, part of analog clock part 2 and digital clock part 3 are rounded. Therefore, one clock part can be constructed compactly, and the display part of one of the clock parts (in this embodiment, the analog clock part 2) can be made large.
There is a mode selector switch 21. Key switch part 22″$
It is possible to provide a large number of switches as shown in FIG. Since the various switches provided in the digital clock section 3 are completely hidden without being exposed to the outside, the number of switches on the exterior can be reduced and the exterior shape of the clock can be made simple. It can also give a sense of luxury. Furthermore, the display digits of the liquid crystal display δ15 of the digital clock section 3 change in accordance with the withdrawal operation of the digital clock section 3, and the information of the mode according to the withdrawal state can be read satisfactorily and quickly.

In addition, the mode changeover switch 21 and the key switch section 2
As mentioned above, the various switches such as 2 and 3 are removably hidden inside the digital storage part 4b of the watch case 4, so there is no need to accidentally operate the switches when carrying the device.
l Operation can be reliably protected from rain. In particular, since the mode selector switch 21 is automatically switched in response to the operation of pulling out the drawer 5 of the digital clock section 3, the operation is easy and the mode can be switched reliably. In addition, the key switch section 22 exposes only the necessary switches depending on the pulled-out state (mode) of the digital clock section 3, which provides good operability, reduces operational errors, and prevents erroneous input.

Although the digital clock section 3 is movable in the embodiment described above, the analog clock section 2 may also be movable. It may be a direction.

In addition, in the embodiment described above, since the analog clock section 2 has three hands, the "day of the week and date" is displayed on the liquid crystal display 2215 of the digital clock section 3, but when the Amerlog clock section 2 has two hands, may display "seconds" on the digital clock section 3.

Furthermore, the present invention is not limited to the above-mentioned electronic wristwatch, but can be widely applied to other timepieces such as pendant watches.

[Effects of the Invention] As explained above, according to the electronic clock of the present invention, at least one of the analog clock section and the digital clock section can be moved! ! Since it is configured so that the display format, external shape, design, etc. can be changed,
We are able to provide watches with a new image that has not existed before, and we are also able to achieve multi-motor and diversification.
Moreover, the digital ffT4ys can be made smaller, and the combination u4y(-) can be closed to create a luxurious feel.
