Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a modular structure of a combination timepiece having a pointer display means and an electric display means. The multifunctionality of watches due to electronicization is rapidly progressing, and in a market situation where a combination watch that combines a digital type with convenience and an analog type with a good appearance is required, the present invention has been developed.
By using liquid crystal panels with wide display areas,
By superimposing pointer display means such as the hour hand, minute hand, and second hand on the bottom of the electric display means that displays a large amount of information on the entire surface and in multiple stages, we take advantage of the advantages of analog display and create several display faces depending on the TPO. The purpose is to provide a watch that can be changed to

The present invention will be explained in accordance with one embodiment with reference to FIGS. 1 to 5. 1 is an analog movement with a recess 2a provided in the long diameter direction of the main plate 2 which serves as the base frame.
The analog movement is positioned in the planar direction by engaging a convex portion 3a provided in the central opening of the reinforcing member 3 made of a metal material, and the supporting feet 3b (three pieces) are fixed to the reinforcing member 3. is arranged so as to surround the analog movement, the foot 3b is made of synthetic resin, and guides holes 4a (3 locations) provided in the spacer member 4 having an opening 4f in which the analog movement is arranged; Further, it guides the holes 6a (3 locations) provided in the board 6 of the circuit means consisting of a rigid printed board 6 on which film-like circuit boards 5 are stacked and mounted, and furthermore, the dowels 4b (3 locations) provided in the spacer member 4 are provided. The circuit holding member 7 made of a metal material guided by the screws 8 (three pieces)
By fixing the screws with screws, the convex portions 4c (plurality) provided on the spacer member 4 press the base plate 2, and also press the bulges 2b (4 locations) provided on the outer periphery of the base plate 2 in the minor diameter direction. Peninsula-shaped protrusions 3c (four locations) provided in the opening of the reinforcing member 3 receive the analog movement 1 to position and fix the cross-sectional direction of the analog movement 1. The foot 3b and the screw 8 constitute a coupling means. Further, the circuit board 5 and the printed board 6 constitute a circuit board member. The surface of the main plate 2 on which the side portion 2b is provided is arranged to be substantially flush with the surface of the reinforcing member 3, and receives the dial 9 uniformly. The dial plate 9 is fixed by pushing the legs 9a (two pieces) fixed to the dial plate 9 into holes 10a (two places) provided in a catch seat 10 made of a synthetic resin material constituting the analog movement. An hour hand 14, a minute hand 15, and a second hand 16 are fixed to the shafts of an hour wheel 11, a second wheel 12, and a fourth wheel 13, which pass through a hole 9b made in the center of the dial 9, thereby forming a pointer display means. . A liquid crystal panel 17 constituting an electrical display means is disposed above the pointer section, and is located between the input signal intake section 17a (two locations) provided at the outer end of the liquid crystal panel 17 in the 12-6 o'clock direction and the circuit means. Elastic conductive rubber 18 (two pieces) is placed on the
(Also, electrical connection is achieved through elastic force)
Elastic hook portions 7a (four locations) provided on the circuit holding member 7 are attached to protrusions 19a (four locations) provided on the panel frame 19 that guides and holds the liquid crystal panel 17.
It is made up of a module by making it land.

The portion of the panel frame that engages with the upper surface of the liquid crystal panel 17 is referred to as a first step portion 19c, and the portion that engages with the exterior case is referred to as a second step portion 19d.

However, with only the dial 9, the elastic conductive portion 18
Because it requires two notches 9c (two places) to escape from the dial 9, it is not possible to create a structure that supports the weight of the analog movement 1, circuit means, etc. around the entire circumference of the dial 9. The plate 9 is bent and deformed, and the liquid crystal panel 1 at the fixed part of the second hand 16 is
Panel crack due to pushing up of 7 or second hand 16
and the scratches on the panel 17, and the circuit holding member 7.
Like the dial 9, the hour hand 14 also lacks rigidity.
If you try to use a liquid crystal panel with a wide display space, there is a risk of fatal defects such as breakage, inability to display, poor display, or stopping due to scratches between the hour hand 14 and minute hand 15. If the analog movement 1 is replaced with a reinforcing member 3 made of a metal material, as described above,
and the circuit holding member 7, and the spacer member 4
and a support leg 3 fixed to the reinforcing member 3 via circuit means.
b and screws 8, and by overlapping the reinforcing member 3 and the dial plate 9, the lack of rigidity of the dial plate 9 and the circuit holding member 7 can be compensated for. In addition, by arranging three foot legs 3b so as to surround the analog movement 1, the analog movement 1 is securely fixed and the rigidity of the module structure is increased.
Furthermore, arranging the elastic conductive member 18 in the direction from 6 o'clock to 12 o'clock is advantageous in terms of the structure of the watch in the following respects.

Since the elastic conductive member 18 is located between the liquid crystal panel 17 and the circuit means arranged above and below the cross-section of the module, it does not interfere with the arrangement of the reuse button, which is an external operation means with excellent operability, and from the design of the watch. This is because the portrait format is better than the landscape format, and the size tolerance is wide.Furthermore, there is no unbalance in the digital display area between 3 o'clock and 9 o'clock, but there is a tolerance between 6 o'clock and 12 o'clock. .

As mentioned above, since cutouts 9c and 3d are required to escape the elastic conductive member 18 in the 6 o'clock-12 o'clock direction of the dial 9 and the reinforcing member 3, the panel frame 19 is
and a shell 20 which is an exterior means via a spacer member 4.
However, in order to securely fix the module, the outer shape of the dial plate 9 and the reinforcing member 3 should be made to match the outer shape of the panel frame 19 and the spacer member 4, and the outer peripheral portions of each should be The spacer member 4 is brought into close contact with the back cover 21 and is further pressed against the back cover 21.
The convex portions 4d (plurality) provided in the panel frame 3 are arranged near the projected outer periphery of the reinforcing member 3 so as to substantially coincide with the portion of the panel frame 19 that is received by the body 20 in a plan view. In addition, the part where the dial 9 and the reinforcing member 3 in the direction from 6 o'clock to 12 o'clock are not provided has the above-mentioned convex portion 4d on the panel frame 19.
A plurality of protrusions 19b are provided so as to overlap with each other in plan view, and the protrusions 19b are bitten into the spacer member 4 that receives the protrusions 19b, thereby increasing the uniformity and reliability of module fixation. In addition, with this structure, it is possible to reduce costs by standardizing many parts, assembly mechanisms, jigs and tools, shortening delivery times, etc. by simply changing a part of the analog movement that is being mass-produced. 2a is additionally installed to minimize the positional deviation of the analog part, and the outer diameter of the dial 2b is made to improve the ease of assembling into the reinforcing member 3. Also, the surfaces of the main plate 1 and the reinforcing member 3 are aligned to make the dial plate By stably and reliably receiving 9, the dial 9 will float,
Warping, etc. can be suppressed, and since the height of the winding stem 22 in the cross-sectional direction is on the dial side, the crown can be placed in the middle of the cross-section of the watch, resulting in excellent operability and design. Further, although the collar 22a provided on the winding stem 22 is determined by the end face of the notch 3e provided on the reinforcing member 3, the winding stem 22 is very long and is prone to buckling and bending due to external force applied to the winding stem. Brim 22a
The spacer member 4 is designed to prevent damage and deformation of the tensioning portion due to a decrease in the amount of engagement with the notch 3e.
The gap in the cross-sectional direction guided by the winding stem 22 is narrowed from the plane direction. Further, the dial plate 9 is positioned and fixed by the analog movement 1, thereby eliminating misalignment with the pointer portion and enhancing the appearance of the display. In addition, as shown in Fig. 4, by making the outer shape of the reinforcing member 3 in the 3 o'clock to 9 o'clock direction slightly larger than the outer diameter of the panel frame 19 and the spacer member 4, it is possible to prevent the module from being damaged by an external force such as a drop impact. Exterior body 20
The external movement of the reinforcing member 3 is received to prevent deformation and destruction of the panel frame 19 and the spacer member 4, and by regulating the amount of movement of the module, the phenomenon of the crown being pulled out is prevented. This makes it possible to prevent problems such as stopping the second hand by operating a regulation lever (not shown in the figure) that engages with the stem 22, and stopping or delaying the pointer part by turning on the reset switch.

Note that it is of course possible to integrate the base plate 1 and the reinforcing member 3 to further increase the rigidity of the module and reduce the number of parts.

In addition, a convex portion 7b is provided in the center of the circuit holding member 7 so as to have a slight gap in cross-section with the analog movement 1, to prevent the analog movement 1 from denting due to the force of fixing the pointer. It also makes it possible to improve anti-magnetic performance and reduce costs.

As mentioned above, a liquid crystal panel with a wide display area is placed above the pointer display means, and while it is possible to display a wide range of information including a world map display and a graphical display, it also takes advantage of the advantages of analog display. This makes it possible to create a combination watch that can change the appearance of a number of different displays, making it possible to greatly contribute to the creation of an attractive product that can appeal even to anti-digital customers.

As described above, according to the configuration of the present invention, the dial plate is placed on the upper surface of the reinforcing member that is coupled to the analog movement together with the spacer member, and the panel frame that holds the display panel is placed on the dial plate.
The locking step part of the panel frame with the exterior case, the dial, the reinforcing member, and the spacer member are placed one on top of the other,
Since each part is held and fixed to the outer case by pressing the spacer member with the back lid, the space between the dial and display panel is set and maintained in a constant state, and the hands and display panel It is possible to provide a combination watch with a thin display part by eliminating problems such as stopping due to sliding.
