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 electrical display means.

The multifunctionality of time openings using electronic f-bis is rapidly progressing, and the combination of the convenient digital type and the good-looking analog type (
In a market situation where a combination watch with a single function is required, the present invention is designed to display hour and minute hands at the bottom of an electrical display means that displays multiple information on the entire surface and in multiple stages using a wide display panel such as a liquid crystal panel.・By superimposing the pointer display means such as the second hand, the advantages of analog display are taken advantage of, and the T
'I want to respond to PO (the purpose is to provide a watch that can change the face of the display).

The present invention will be explained with reference to Figs. 1 to 5 along with a practical case. 1 is an analog movement, and a convex part 3a provided in the central opening of a reinforcing member 3 made of a metal material is engaged with a concave part 2a provided in the longitudinal direction of the main plate 2, which serves as the base frame, to form an analog movement. The support feet 3b (5 pieces) are positioned so as to surround the analog movement, and the support feet 3b (5 pieces) are fixed to the reinforcing portion 3 in the planar direction. Holes 6a (six locations) provided in the circuit board 6 of the printed circuit board 6, which guides the holes Aa (three locations) and supports the rigidity of the printed circuit board 6 mounted by stacking film-like circuit boards 5. guide and
Furthermore, the circuit support member 7 made of a metal material guided by the dowels Ab (5 pieces) provided on the spacer member 4 is screwed with screws 8 (5 pieces).
By fixing the screws with screws, the convex portions AC provided on the spacer member A stamp the base plate 2, reinforcing the flattened portion 2b provided outward in the short diameter direction of the flat base plate 2. Peninsula-shaped protrusion 6C provided in the opening of member 6
(4 pieces) are received to position and fix the cross-sectional direction of the analog movement 1. The surface of the main plate 2 on which the side portion 2b is provided is arranged so as to be substantially flush with the surface of the reinforcing member 6, and receives the dial 9 uniformly. The legs 9a (two pieces) fixed to the dial plate 9 are pushed into holes 10a (two places) provided in a catch seat 10 made of a synthetic resin material constituting an analog movement to fix the text plate 9. The tube gii passed through the hole 9b made in the center of the dial 9, No. 2 fAil 2
．． An hour hand, a minute hand 15, and a second hand 16 are fixed to the shaft portion of the fourth stop 13 to constitute a pointer display means. The liquid crystal nozzle 17 constituting the electrical display means is arranged above the pointer section, and the input signal intake section 17a (two locations) provided at the outer end of the liquid crystal nozzle 17 in the 12 o'clock-6 o'clock direction. A protrusion provided on the panel frame 19 that guides and holds the liquid crystal nozzle 17 in such a manner that an elastic conductive rubber 18 (two pieces) is disposed between the liquid crystal nozzle 17 and the liquid crystal nozzle 17 so as to achieve electrical connection by neutral force. A module is constructed by attaching lifting portions 7a (A locations) having a yuzen property to the circuit support member 7 at 19a (4 locations).

However, since the dial plate 9 alone requires notches 9C (two places) to escape the neutral conductive part 18 in a plane, the dial plate 9 has a structure that supports the weight of the analog movement circuit means etc. all around the dial plate 9. The dial plate 9 is bent and deformed due to external disturbances such as a drop impact, and the panel cracks due to the liquid crystal panel 17 of the fixed part of the second hand 16 being pushed up.
6 and the dial 17, and the circuit support member 7 also lacks rigidity like the dial 9, so the hour hand 1A comes off.
There is a risk of fatal defects such as breakage, inability to display, poor display, and stoppage due to loosening and scratches between the hour hand 1A and minute hand 15, and if you try to use a liquid crystal panel with a wide display space, it will be a problem. The analog movement 1 is placed between the reinforcing member 5 made of a metal material and the circuit supporting member 70, and the supporting member is fixed to the reinforcing member 3 via the spacer member 4 and the circuit means. 3b and screw 8, tighten the screws, and then attach the sleeve plate 3 and the dial 9.
By overlapping the dial plate 9, the lack of rigidity of the circuit leg member 7 is overcome. Further, by arranging the three supporting legs 3b so as to surround the analog movement 1, the analog movement 1 is completely fixed and the rigidity of the module structure is increased.

Arranging the penetrating 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 panels 17 and the circuit means arranged above and below the cross section of the module, it is an external operation means with excellent operability.1) It does not interfere with the arrangement of the button. ■Due to the design of the watch, a vertical watch is better than a horizontal watch, and there is a wider range of size tolerances.Furthermore, an imbalance between 6 o'clock and 9 o'clock in the digital display area is not allowed, but an imbalance between 6 o'clock and 12 o'clock is acceptable. This is because it has a range. As mentioned above, the panel frame 19 and the spacer member A are required to have notches 9c and 3d that escape the elastic conductive member 18 in the 6 o'clock-12 o'clock direction of the dial 9 and the reinforcing member 3. Although the portions that are clamped by the body 20 and back lid 21, which are exterior means, are limited, in order to securely fix the module, the outer shapes of the dial plate 9 and reinforcing member 3 are the same as the outer shapes of the panel frame 19 and spacer member 4. y. The convex portions Ad (plurality) provided on the spacer member 4 which are aligned and pressed against the back lid 21 are placed near the projected outer periphery of the reinforcing member 3.
In addition, it is arranged so as to coincide with the portion of the panel frame 19 that is received by the body 20 in plan view.

1^j, the large parts of the dial 9 and the reinforcing member 3 in the direction from 6 o'clock to 12 o'clock are received by providing protrusions 19a (plurality) on the panel frame 19 so as to overlap the protrusions 4d in a plane. The module is made to bite into the spacer member t to improve uniformity and reliability of module fixation.

With this structure, it is possible to reduce costs by standardizing a large number of parts, assembly machines, jigs and tools, and shortening delivery times by simply changing a part of an analog movement that is being mass-produced.
The base plate 1 t, I - No additional four parts 2a are installed in the long axis direction to minimize the total deviation of the analog part (i), and the roughening 2b is made on the outer periphery of the outer diameter of ``P'' to improve ease of incorporation into the reinforcing member 6. Align the surfaces of the main plate 1 and the reinforcing member 3, which have been cut by a high percentage, and remove the dial plate 9.
By receiving it stably and reliably, the dial 9 is lifted,
Warping, etc. can be suppressed, and since the height of the winding stem 22 in the cross-sectional direction is on the dial side, 1) the use case can be placed in the middle of the cross-section of the watch, which is excellent in terms of operability and design. Sumdamaki Shin 22
The collar 22a provided on the reinforcing member 5 is determined by the end face of the notch 3e provided on the reinforcing member 5, but the winding stem 22 is very long.
The guide of the winding X22 of the spacer member 4 is designed to prevent buckling and bending due to the external force applied to the case. The gap in the cross-sectional direction is narrowed from the plane direction.The positioning and fixing of the dial plate 9 is done by the analog movement 1, and the positional deviation from the pointer part is avoided (to improve the appearance of the display. 4 As shown in Figure 4, the reinforcement part profit 3-5
By making the outer shape in the time-9 direction slightly thicker than the outer shape of the panel frame 19 and the spacer member A, the outer shape of the reinforcing member 6 prevents the module's exterior from moving within the body 2o against external forces such as a drop impact. Stop the receiver at the part and attach the panel frame 19.
．． By preventing deformation and destruction of the spacer member 4 and regulating the movement of the module, the phenomenon of the crown being pulled out is prevented, and the needle needle is stopped by the operation of a regulating lever (not shown in the figure) that engages with the winding stem 22.・It is possible to prevent problems such as the pointer stopping or delaying due to the reset sonar being turned on.

Of course, it is also 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 at the center of the circuit holding member 7 so as to leave a slight gap in cross section with the analog movement 1, so that the analog movement 1 receives the force from fixing the pointer.
In addition, the use of stainless steel material allows for anti-magnetic performance and cost reduction.

As mentioned above, by placing a liquid crystal panel with a wide display area above the finger button display means, it is possible to display a wide range of information including world map display and graphical display, while also taking advantage of the advantages of analog display. It would be possible to create a combination watch that can change the face of the street display, which could greatly contribute to creating an attractive product that can appeal to anti-digital customers.
