JPH0720266A - Pointer type watch - Google Patents

Abstract

PURPOSE:To extend the general purpose function and the degree of freedom in the design of appearance without requiring any bezel by arranging an analog movement such that the pointers are located in the opening of a liquid crystal display member. CONSTITUTION:A liquid crystal display member (film liquid crystal) 13 is formed into an annular or rectangular ring having an opening and bonded through a both-sided adhesive tape to the housing of an analog movement being arranged in a watch case 1. Consequently, the pointers 7, 8 are located in the opening of the display member 13. The display member 13 is connected through an electrode forming part with a circuit board which delivers display signals for arbitrarily selecting display functions other than time display function, e.g. timer function, stop watch function, slide rule function, azimuth confirming function. This constitution provides a function similar to or better than that of a bezel without actually requiring any bezel while allowing free selection of design.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pointer type timepiece that displays time in analog.

[0002]

2. Description of the Related Art In a wristwatch, a pointer-type timepiece that displays the time with a pointer has been known. In this pointer type timepiece, a structure is known in which a function is provided other than the time display and a rotary bezel is provided in order to improve the appearance design.

22 and 23 show the structure of a conventional timepiece provided with this bezel. A watch glass 110 is fitted and fixed to the upper surface of the watch case 100, and a back cover 120 is attached to the lower surface of the watch case 100. A dial 130 is arranged inside the watch case 100 to display the time with hands. A rotary bezel 140 is attached to the upper part of the watch case 100 outside the watch glass 110. The lower surface of the bezel 140 is engaged with a lock member 150 such as a leaf spring attached to a corresponding portion of the timepiece case 100, which restricts rotation in one direction and provides a sense of moderation during rotation. Has been granted. This bezel 14
As shown in FIG. 22, numerical values are displayed at 0 by printing, and a timer function, a slide rule function, a direction confirmation function, and the like are provided by rotating the bezel.

[0004]

In the conventional timepiece, since the predetermined function is expressed by the hands arranged in the timepiece case 100 and the display contents of the rotating bezel, the rotating operation of the bezel is necessary. However, the operation is troublesome, and the outer shape of the watch case needs to be round, which imposes restrictions on the design. Moreover, the bezel only expresses one function related to the displayed content, and is not versatile enough to express multiple functions.

The present invention has been made in consideration of the above circumstances, and provides a pointer type timepiece having a function similar to or greater than that of a bezel without providing a bezel and having a greater degree of freedom in design. The purpose is to provide.
