【Example】

 The present invention will be specifically described below based on the embodiments shown in the drawings. FIG. 3 shows an embodiment according to the present invention in which the TIME mode is selected by operating the external operating member. The mode hand 7 indicates “TIME” on the mode display portion 14 and the dial window 10a is displayed. The liquid crystal panel 11 displays a number display section 11b indicating the time, a character display section 11a of the alphabet indicating the day of the week, and a date display section 11c. In this embodiment, by selecting the time mode, the mode hand 7 of the mode display section 14 is made to point to "TIME", and the alphabet display "MON" is displayed on the character display section 11a of the liquid crystal panel 11 corresponding to the time mode. Characters are displayed so that it is possible to know that it is Monday. Further, the liquid crystal panel 11 displays a number display portion 11b of "1 to 12" indicating the time and a date display portion 11c indicating the day, and the pointer A13a, the pointer B13b, and the pointer C13c are the numbers and characters displayed on the liquid crystal panel 11. The scale portion 15 on the outer circumference of the plate is pointed out, and it can be seen that the current time is 10:08:42.

FIG. 4 is a diagram when the timer mode is selected by operating the external operation member, and the mode hand 7 indicates “TIMER” of the mode display portion 14 and the liquid crystal through the dial window 10a. The panel 11 is adapted to display a number display portion 11b indicating the remaining time such as "05-60". At this time, the character display portion 11a is used when the remaining time is larger than the minute.

The pointer C13c reverses while indicating the remaining time in seconds, and the pointer B13b reverses while indicating the remaining time in minutes. This example shows that the remaining time is 8 minutes and 42 seconds. FIG. 5 is a diagram when the calendar mode is selected by operating the external operation member. When the mode hand 7 indicates “CALENDER”, the month display portion 11d indicating the month is displayed on the liquid crystal panel 11 through the dial window 10a. A character display section 11a for displaying days of the week and a day display section 11c for displaying days are provided. In this embodiment, characters representing the month such as "JA-DE" are displayed on the month display portion 11d. In addition, the character display portion 11a displays a character display portion 11a representing the day of the week as "MON", and the date display portion 11c representing the date is displayed as a number "1". In this embodiment, "MON 1 ", Indicating that it is one day on Monday.

The scale 15 on the outer circumference of the dial, which is indicated by the pointers B13b and C13c, indicates the number of the year, and the characters of the liquid crystal panel 11 indicated by the pointer A13a are displayed. Since it represents the month, this example represents that it is Monday, February 1, 1993.

FIG. 6 is a diagram when the dual time mode is selected by operating the external operating member, and the mode hand 7 indicates “DUALTIME”. When the time difference is input with the operation button 16, the pointer A13a is rotated by the time difference, and the number display portion 11b of the liquid crystal panel 11 displays a number representing "1 to 24" time.

The character display portion 11a of the liquid crystal panel 11 displays characters representing the days of the week, and in the present embodiment, “SUN” is displayed, indicating that it is Sunday. Further, "31" is displayed on the day display portion 11c adjacent to the day of the week display, indicating that it is 31st.

Next, in order to investigate the time in New York by an external operation, -10 hours was set by the external operation. Then, the liquid crystal panel 11 was displayed in the afternoon, indicating that it was 20:08:42.

The mode switching operation will be described below with reference to FIGS. 7 and 8. A corner portion that engages with a square hole of the clutch wheel 2 is formed at the tip of the winding stem 1 which is an external operation portion. A gear that meshes with the correction transmission wheel 3 is formed on the outer peripheral portion of the clutch wheel 2.

The correction transmission wheel 3 is rotatably supported by the main plate 12 and meshes with the correction wheel 4. Further, the correction wheel 4 has a modified hole that engages with the display stem 5. The display stem 5 is locked by the correction spring 6, and the position in the rotation direction is regulated. Further, as shown in FIG. 8, the display stem 5 has a deformed shaft for fixing the mode hand 7 to the tip portion protruding from the dial 10 and engaging with the correction wheel 4.

Further, the contact spring 8 is engaged with the display stem 5 and is pressed against the circuit board 9. By rotating the winding stem 1 which is an external operation unit, the rotation is transmitted to the clutch wheel 2, the correction transmission wheel 3, the correction wheel 4 and the display stem 5.

Further, the display stem 5 is unlocked from the correction spring 6 and the contact spring 8 rotates, and a signal is input to a different pattern on the circuit board 9 to operate an electronic circuit (not shown). By controlling, the display of the liquid crystal panel 11 and the position of the pointer are changed. The mode hand 7 also rotates to display the mode switching.

9 and 10 are external views of a timepiece according to another embodiment of the present invention. In FIG. 9, the liquid crystal panel 11 is constituted by a dial plate, the mode hand 7 indicates "TIME", the liquid crystal panel 11 displays numbers "1 to 12" indicating the time, "MON 1", etc. The display shows the day of the week and the date.

Further, it is understood that the current time is 10: 8: 42 by the instructions of the pointer A13a, the pointer B13b, and the pointer C13c. In FIG. 10, the liquid crystal panel 11 is configured by using a dial instead, and the mode display is switched by the liquid crystal. When the mode is set to time with the external operation member, the character "TIME" of the mode display unit 14 is surrounded by a frame. At the same time, the display on the liquid crystal panel 11 becomes a number indicating the time "1 to 12" and a display indicating the day of the week and date such as "MON 1".

Further, it is understood that the current time is 10:08:42 by the instructions of the pointer A13a, the pointer B13b, and the pointer C13c. Similarly for the other modes, the LCD panel uses the dial itself instead of the dial window, so the display size can be expanded and is easy to read.

[0025]

[Effect of device]

 As described above, according to the present invention, part or all of the dial in the multi-function timepiece is composed of the liquid crystal display member, and the electric signal due to mode switching is displayed on the liquid crystal display member in the form of characters or numbers.

In addition, a pointer is used in correspondence with each function, and time is displayed in correspondence with many modes by combining letters and numbers on the liquid crystal display member and the pointer. Therefore, it is not necessary to pre-print letters, numbers, scales, etc. that can be used in any mode on the dial, and the display screen changes for each mode, making it easier to read. .

Further, similarly, there is no need to prepare a special pointer for mode support, and the display in each mode can be supported only by the conventional hour hand, minute hand, and second hand. Therefore, the number of parts can be reduced in this respect. You can
