[Example] Hereinafter, the present invention will be described in detail by giving examples according to the drawings.

1 and 2 are a plan view and a sectional view taken along the line A-A' in FIG. 1, showing an embodiment of the present invention.

In FIG. 1, a pointer display block 10 is arranged approximately in the center of the watch body, and a changeover switch block 20 is placed around this in the 3 o'clock direction.
A motor block 30 is arranged at the 9 o'clock direction, an electro-optical display block 40 is arranged at the 12 o'clock direction, and a battery 50 is arranged at the 6 o'clock direction. Further, a circuit block 60 is arranged on the top surface of the changeover switch block, pointer display block, motor block, and electro-optic display block.

In the embodiment of the present invention, the electro-optical display block refers to a digital display section using a liquid crystal panel, and as described above, it is arranged on the outer circumference of the clock in the 12 o'clock direction. The outer periphery of the main plate 11, where the digital display section is arranged, is cut into a U-shaped shape, leaving peninsula-shaped protrusions 11a and 11b on the 3 o'clock and 9 o'clock sides.
Reference numeral 41 designates a panel frame which, while holding the liquid crystal panel 42, contacts the peninsula-shaped protrusions 11a and 11b of the main plate 11 as supporting parts, and inserts the circuit block 60 from the side opposite to the upper surface of the main plate on the dial mounting side. The changeover switch block, pointer display block, motor block, and electro-optical display block are held together and fixed with screws to form the watch body. This structure will be explained in more detail with reference to FIGS. 1 and 2.

In FIG. 1 and FIG. 2, the upper surface and side portions of the liquid crystal panel 42 are held, and the center portion of the base plate 11 is lower and the outer peripheral portion of the base plate 11 is higher. An opening 41h is formed in which the surface is exposed, and the holding parts 41a,
41a' and a through hole 41e formed in the panel frame 41
Two receiving parts 41b, 41 with spring properties
b', and an opening 41 below the holding parts 41a, 41a'.
The panel frame 41, in which an inner wall 41c larger than h is formed, is cut into a part of the outer periphery of the base plate 11 in the shape of a U, and has opposing peninsula-shaped protrusions 11a, 1.
1b from the side opposite to the dial 13.
The screw pin 12 is set so as to penetrate through the bottom surface of the panel frame 41, and is positioned to engage with the screw pin 12 set up on the lower surface 11d of the projections 11a and 11b of the main plate 11 on the opposite side from the upper surface 11c on the dial mounting side. 41d, is held by a circuit board that engages with screw pins 12, and is fixed to base plate 11 with screws 15.

The liquid crystal panel 42 includes a polarizing plate 43 and an upper glass 4.
4. It is composed of a lower glass 45, and like the panel frame 41, it is inserted from the opposite direction from the dial, and the receiving parts 41b, 4 provided in the panel frame 41 are inserted from the opposite direction from the dial.
1b' and the inner wall 41c.

Reference numeral 46 denotes a reflecting plate, which is positioned by a reflecting plate seat 47 in both the cross-sectional direction and the planar direction. 48 is a conductive rubber connector, which connects the conductive pattern 44a of the upper glass 44 of the liquid crystal panel and the conductive pattern 61a of the circuit board 61.
It has the function of electrically coupling the liquid crystal panel 42 to the panel frame 41 and holding the liquid crystal panel 42 against the panel frame 41. The liquid crystal panel 42, the conductive rubber connector 48, the reflector seat 47, and the reflector 46 are attached to the panel frame 41 while being held by the holding portion 41a of the panel frame 41.
1 and screw pins 12 as guides, the base plate 11 and a circuit board 61 supported by a circuit blower 60 are vertically clamped, and are firmly fixed with screws 15. 14 is a dial ring which is a parting member of the liquid crystal panel 42. The position of the liquid crystal panel 42 in the planar direction is such that the end surfaces of the upper and lower glasses 44 and 45 of the liquid crystal panel are in contact with the receiving part 41b of the panel frame, which has a bridge-like shape with a through hole 41e and has a spring property, and the spring Depending on the structure, the upper and lower glasses 44 and 45 are pressed against the inner wall 41c of the panel frame 41, which faces the receiving portion 41b, and are held in a fixed position.

As shown in FIG. 2, the display surface of the liquid crystal panel 42 is arranged so that the outer circumferential side is higher than the upper surface of the dial 13 of the pointer display block (analog display section), and is tilted downward toward the center of the watch. be. This means that when the watch is worn on the wrist, the area that falls within the field of view of the digital display screen is kept secret, making it easier to see. 62 is a circuit receiver that constitutes a circuit block;
It has the function of holding the panel frame 41 and liquid crystal panel 42 more reliably.

The structure of the present invention is as described above, and in this example, the panel frame, liquid crystal panel, and reflector seat are sequentially set on the main plate, but it is of course possible to form the components into blocks in advance and then assemble them. It is. Furthermore, the liquid crystal panel is tilted with respect to the dial, and as mentioned above, it is easy to see when worn on the arm, but the display body (liquid crystal panel)
In order to incline the angle, it is most effective to use a structure or an incorporation method as in the present invention.

[Effects of the invention] As described above, according to the invention, the holding portion 41a of the panel frame is attached to the peninsula-shaped protrusion that is cut out from a part of the outer periphery of the machine frame in the shape of a square. By positioning the receiving portion 41b and the inner wall 41c of the panel frame at a position facing the receiving portion 41b, the electro-optical display means does not overlap the main plate and is not provided outside the outer periphery of the main plate, thereby saving space. In addition, by using the outer periphery of the panel frame as a connecting part between the watch case and the mechanical body, it has the advantage of being able to be connected without any members such as an inner frame. In addition, since the watch according to the embodiment has a structure in which most of the functional parts constituting the watch are placed on the surface opposite to the main plate, the display surface of the digital display is in the same direction as the dial, but the display By sequentially assembling the components of the digital display section from the opposite side of the screen, it is possible to assemble from only one direction, which improves assembly workability and allows only the minimum necessary display surface to be exposed. It also has an excellent appearance.
