Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an analog electronic wrist watch having multifunctional display means such as chronograph display and timer display.

[0002]

2. Description of the Related Art In recent years, there has been a strong demand for analog electronic timepieces to have multiple functions such as chronographs, alarms and timers, and manufacturers have commercialized various multifunctional analog electronic timepieces to meet these requirements. There is. Also, when displaying such a multi-function, normal seconds, hours,
In addition to the minute hand, a small second hand, alarm hour and minute hand, etc. are used, and a special small window is provided at any position on the dial, such as the 6 o'clock position or 9 o'clock position, to display functions such as alarm time. Has been done.

In addition to the usual crown and winding stem, sub-winding stems and switches for switching multi-function modes are used in addition to the usual ones.

[0004] This allows not only to be equipped with multiple functions but also to develop various variations in the watch design, thereby enhancing the appeal to the diversifying needs and preferences of consumers.

As disclosed examples of such a multifunctional electronic timepiece, Japanese Patent Laid-Open Nos. 61-287683 and 61-2943 are available.
88, Public Utility Model Sho 61-26191, etc.

In the pointer-type display timepiece to which such a function is added, the number of watch wheels constituting each function is also different from the usual one, and the number thereof is increased. Therefore, repairability in after-sales service is desired, and it is important to clarify the positions where a plurality of wheels are installed.

In order to solve this problem, conventionally, a hole corresponding to the wheel & pinion is formed (for example, in the case of the third wheel and pinion, three holes are formed in the gear portion) or a resin-made wheel & pinion. In the case of, a plurality of cars have been identified by changing their colors.

Further, in the case of having a function such as a chronograph and a timer, as a measuring function, the position of the pointer is required to be more accurate according to the normal time display pointer.

Therefore, in order to reduce backlash and improve the accuracy of the needle position, hitherto second pressing springs have been used. However, in the case of a multifunctional timepiece, since the hands are provided at several places, a plurality of second pinion holding springs have been used for each of the hands equipped with the hands.

[0010]

However, the conventional multifunctional electronic timepiece requires a separate moving structure and an IC for driving, depending on the combination of the added functions. That is, if the arrangement of the function display section is changed, the movement structure and the arrangement of parts must be changed, and when adding or deleting functions or changing the operation specifications, a new IC must be prepared accordingly. I have to. As mentioned above, in order to meet the needs of consumers and to provide a wide variety of watch designs and functions, manufacturers have been forced to make high-mix low-volume production.

Under these circumstances, the conventional multifunctional electronic timepiece has a problem that the die cost associated with the component change, the mask cost associated with the processing cost or the IC change, and the cost for the design change are increased. As a result, the unit price of the multifunctional electronic timepiece will increase. In addition, providing the parts layout and IC specifications with redundancy so that one model of electronic timepiece can satisfy various specifications will lead to an increase in watch size and cost.

As described above, the conventional multifunctional electronic timepiece has a drawback that it cannot meet the diversified demands.

Therefore, the present invention eliminates these drawbacks, and the purpose of the present invention is to reduce the load on designing and manufacturing, and to diversify the market without the need for cost increase or size enlargement. It is to provide a multifunctional electronic timepiece that can easily satisfy the demand and has an excellent design.

Further, in the conventional marking method of a plurality of hour wheels of a pointer-type multifunctional electronic timepiece, each hour wheel can be identified, but it is impossible to judge even the assembled position. Needle-type watches that display only normal time, of course, have many watch wheels used in multi-function watches, and their built-in position is not clear in assembly and after-sales service. In this case, a fatal defect such as a stop of the watch body due to a difference in the number of wheels installed. In addition, the number of man-hours required for assembling the timepiece body and for assembling after-sales service is also increased, which directly leads to the cost increase. In particular, in recent years, there is an increasing need for trains that rotate at high speeds, so that it is becoming more and more popular to use resin-made wheels with low inertia moment. The resin-molded wheel and wheel are inferior to the metal wheel and wheel in terms of shaft and gear strength. If the assembly position is incorrect, shaft breakage, tooth profile deformation, etc. can be easily induced. . In addition, the conventional means such as making holes in the gears to identify the number wheels complicates the structure of the mold for resin molding, leading to deterioration of dimensional accuracy and a cost factor. Will end up.

Therefore, the present invention provides a multi-function electronic timepiece having a plurality of timepieces, in which the position of the hour wheel is clearly defined and which can be easily assembled.

In addition, in the conventional second pinion spring structure of a multi-function timepiece, it is necessary to attach a dedicated second pinion spring to each wheel in order to reduce the backlash of a plurality of pointer wheels, which increases the number of parts, It will become a factor of the body's costume. In addition, a structure for fixing each second spring is required, which complicates the structure of the timepiece body and deteriorates after-sales serviceability.

Therefore, the present invention provides a second pinion spring for a multifunctional timepiece having a simpler structure.

Further, by rewriting software in the program memory, an operation signal generated from the microcomputer is determined, and a display operation corresponding to the display position is performed.

Further, in the base frame made of a synthetic resin and the train for displaying the normal time and the train for displaying the additional function, the base frame near the incorporation position of each of the trains and the corresponding wheel trains The feature is that they have the same marking.
