Problems solved by technology

[0008] However, in the prior art, the shape of the first groove is a straight line, and the pin of the arm moves the needle in the radial direction at a predetermined cycle, and at the same time rotates the needle.
Therefore, the movement locus of the indication part of the needle is limited to a shape that is symmetrical with respect to the rotation center of the guide arm, so there is still a problem in drawing a complex movement locus with excellent creativity.
In addition, in general, when the moving locus of the pointer indicating part is formed into a complicated locus, there is a tendency that the display mechanism also becomes complicated.

Embodiment Construction

[0042] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0043] Hereinafter, a mechanical wristwatch (corresponding to the "clock" in the claims) and a movement incorporated in the watch (corresponding to the "clock movement" in the claims) according to the embodiment will be described first, and then the display The details of the organization are described.

[0044] (clock)

[0045] Generally, a mechanical body including a driving part of a timepiece is called a "movement". The state in which the dial and hands are attached to the movement and put into the watch case to form a finished product is called "complete" of the watch. Of the two sides of the bottom plate constituting the timepiece substrate, the side where the watch case glass, that is, the side where the dial is, is referred to as the “back side” of the movement. In addition, the side where the case back cover of the timepiece case exists, that is, the side op...

Abstract

The invention relates to an indicator provided with a display mechanism (42) that draws a complex path including a timepiece movement and a timepiece including this display mechanism. The indicator (42) is used to display a temporal greatness. A control mechanism (50) changes its movement speed in relation to the passage of time while alternately toward and away from the center (C1) of a display region (15). The movement of the indicator is thus carried along portions of curves connected by inflection points (P1-P8).

Description

technical field [0001] This invention relates to a display mechanism, a watch movement including the display mechanism, and a timepiece. Background technique [0002] In addition to the function of displaying time, mechanical clocks such as watches also have the function of being decorations. Therefore, conventionally known mechanical clocks are equipped with a special display mechanism in order to improve creativity in displaying information such as time or day of the week with respect to hands such as hour hand, minute hand, second hand, and day hand. [0003] For example, Patent Document 1 describes an analog display device having a control device for an indicator that is attached to a rotating shaft and has a preselected path of an indicator of a value to be displayed ( display mechanism) and are configured such that the free end of the indicator follows a preselected path as it rotates about the axis of rotation. [0004] The control of the indicator has a longitudina...
