Abstract

PURPOSE:To obtain a time-piece having the information of a chronograph (CG) mechanism simple in operation addeda thereto, by arranging a clock movement displaying usual time to the center of a time-piece and arranging a plurality of modules for displaying informations by hands arround said movement. CONSTITUTION:A plurality of CG time display modules displaying a plurality of informations using a plurality of hands are arranged around a usual time display movement. Since usual time display is performed by the hr hand 1a, min hand 1b and sec hand 1c provided to the central part of a time-piece, this time-piece can be used without being different from a usual hand type clock. CG sec display is performed by the 30 sec-advance of a CG sec hand 3 and the elapse time of CG sec can be easily read by the 30 sec-display scale of the CG min hand 2 of a CG min display part. Further, since a usual time display hand control circuit and a CG time display hand control circuit are respectively independent, CG measurement can be easily performed by two external operation buttons, that is, button 5 having start/stop function and a reset button 6.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a pointer display type electronic timepiece in which information is obtained by a plurality of hands in addition to the normal time information displayed by the hour hand, minute hand, etc. This relates to the arrangement structure of a pointer driving module that displays a plurality of pieces of information.

[Background of the invention]

The development of electronic watches in recent years has been remarkable, and in particular it has become common to add chronograph (stopwatch) functions to digital watches, and they are now becoming popular and even inexpensive.

On the other hand, in the market, the need for wristwatches with chronographs (hereinafter referred to as CG) has increased in addition to pointer display electronic watches.
Recently, products with CG functions have begun to appear rapidly. These are relatively expensive, difficult to operate, etc., and are satisfactory guidelines for lower prices, which are one of the two polarizations of pointer display type electronic watches (high-end products and low-priced products). There are few electronic watches with CG display.

Against this background, the present invention aims to reduce the cost of the timepiece movement by reducing the number of parts and standardizing parts when adding a chronograph function to a pointer display type electronic timepiece. The purpose is to consider a structure that is easy to see and easy to operate.

[Conventional technology]

Pointer display type electronic watches with CG functions have recently appeared rapidly, but on the other hand, like the CG mechanism of conventional mechanical pointer watches, the CG hour hand, CG minute hand, and 00 second hand have a return-to-zero structure. There is an electronic timepiece in which a mechanical slip mechanism consisting of a heart cam or the like is provided on each pointer shaft, and the connection with the hour hand, minute hand, and second hand for normal time display is separated and controlled by an external operating member.

However, in the case of such a zero return structure, the 00 hour hand axis, CG
There is no major problem with the minute hand axis, but providing the aforementioned mechanical slip return mechanism on the CG second hand axis, which has weak rotational torque, not only requires parts with strict precision, but also
The mechanical slip return mechanism of the pointer shaft requires a large number of complicated interlocking levers, is thick in structure, and has the disadvantage of increasing cost.

In addition, increasing the rotational torque of the CG second hand shaft to the same level as that of a mechanical CG watch requires a correspondingly large amount of energy, and in the case of an electronic watch, a large, high-capacity battery is required. size,
This results in a very unsatisfactory watch that does not suit the current situation where thickness etc. are becoming smaller.

On the other hand, in order to avoid the above-mentioned problems,
The electronic watch described in Publication No. 6886 has a step motor that rotates the hour hand, minute hand, and second hand, which normally display the time, via a gear train, as well as a minute CG hand, a second CG hand, and a 5/5/2 CG hand that displays the CG time. A clock structure has been devised in which a plurality of step motors are added to independently drive each of the 100-second CG hands, and each CG hand is controlled by an electrical signal.

[Problem that the invention seeks to solve]

However, in the electronic timepiece, the plurality of step motors and the pointer wheel train are arranged so that they do not overlap each other in a plane except for some overlap, and the external operation switching mechanism, battery, etc. It has a planar layout structure that eliminates overlapping. The area occupied by the external operation switching mechanism, the step motor for normal time display, and the hand wheel train in the watch movement is centered on the second arm 9 and the winding stem 46.
It is fan-shaped at approximately 90 degrees from the extension line and occupies a space close to the outer periphery of the watch movement.

As a means of reducing the cost of watch movements, for example, the fan-shaped watch movement can be used in common with other watch movements by using the following method, which has been widely used in the past. It is difficult to plan.

In other words, it is a method to obtain a large-sized men's movement by enlarging the main plate, which is the base plate of a small watch movement, and commonly using the time display movement. This is a method to increase mass production efficiency and reduce costs by using common parts.

As described above, the timepiece movement of the above-mentioned pointer display type multi-hand electronic timepiece becomes a dedicated movement for the electronic timepiece with CG.

In addition, since the era of mechanical watches, the market share of pointer watches with CG has been extremely limited compared to three-hand watches, two-hand watches, etc. that normally display the time, and the demand for pointer watches with CG has been limited. The quantity is smaller than other pointer display watches. Even now, with the transition from mechanical watches to electronic watches, the demand for electronic watches with CG is lower than that of other electronic watches with pointer displays, so it is difficult to reduce costs through mass production. Hard to be a clock.

As described above, the conventional electronic timepiece chronograph with pointer display has various drawbacks, and no one has yet appeared that satisfies users.

[Purpose of the invention]

The purpose of the present invention is to eliminate the above-mentioned drawbacks, standardize parts, reduce the number of parts, and lower costs.
The purpose of this invention is to provide a pointer display type electronic timepiece that is easy for the user to read, is easy to operate, and has additional information such as a ronograph mechanism.

[Means for solving problems]

To achieve the above object, the present invention provides an electronic watch configured to display information using a plurality of hands in addition to a hand that normally displays the time, such as an hour hand, a minute hand, etc. that display at least the normal time in the center of the watch. It is characterized by a clock movement that displays time information, and a module containing multiple motors that display multiple pieces of information using hands around it.

〔Effect of the invention〕

As is clear from the above embodiment 1.2, according to the present invention, a plurality of CG time display devices configured to display a plurality of information using a plurality of hands are arranged around a movement that normally displays time. By arranging the module, it is possible to reduce the cost of the normal time display movement, and most of the CG time display modules can be used in common, reducing costs due to mass production, making it possible to create an inexpensive pointer display type. You can get a multi-hand electronic watch.

Also, the normal time is displayed by the hour hand, minute hand, and second hand in the center of the watch, so it is no different from a normal pointer type watch (it can be used and is easy to read, and the CG second hand is displayed by the CG second hand. The elapsed time in CG seconds can be easily read by the 30-second display scale of the C0 minute hand, which is displayed in 30 decimal format and is provided in the CG minute display section, so the user can easily read the elapsed time in CG seconds.
G time is easier to read.

Furthermore, since the pointer control circuit for normal time display and the pointer control circuit for CG time display are each independent, CG measurement can be easily performed by freely operating the two external operation buttons.

In addition, each pointer wheel to which each CG pointer is attached has a cross-sectional configuration in which it is pivotally supported by the main plate and back plate, so there is as little cross-sectional overlap as possible with the elements that make up the movement for normal time display. C is advantageous for watch design
This not only makes it possible to arrange the G pointer on a plane, but also provides a timepiece with a slim design that can keep pace with the recent trend towards thinner electronic timepieces with pointer display.
