Conventionally, this type of switch structure was developed in 1983.
No. 143633 (Utility Model Publication No. 56-31968) is known.
In this switch structure, in an electronic watch that uses a circuit board with a wiring electrode pattern formed on only one side, a fixing plate with a switch spring integrally formed on the other side of the circuit board is stacked on top of the other, and the switch spring is The feature is that the switch circuit is turned on and off by hooking it to the wiring electrode pattern side of the circuit board and sliding it in the plane direction while pressing the circuit board.With this structure, the fixed board is connected to the circuit board. To prevent the switch spring from hitting the circuit board, care must be taken to release the switch spring part to the side, but this has drawbacks such as bending and changing the switch stroke, and also prevents the switch spring from hitting the circuit board. It was difficult to assemble, and automatic assembly machines were not suitable for mass production.

For a watch with this structure, first insert the liquid crystal panel 5 into the panel frame 7, then insert the connector 6, fit the switch spring 8 into the dowel 7A, and then connect the battery negative terminal 10. Then, the circuit boards 1 are placed one on top of the other, and heat caulking is performed. This thermal caulking is done by melting and crushing the tips of the dowels 7A, 7A, 7A with a hot chisel to create a larger diameter portion 7' than the hole 1A of the circuit board 1 and fixing the panel frame 7. , a liquid crystal panel 5, a connector 6, a circuit board 1, a switch spring 8, and a battery negative terminal 10 are integrated. At this time, the switch spring 8 is laminated on the pattern of the circuit board 1, but since an insulating layer 1' such as a solder resist is provided directly under the switch spring 8 to increase the insulation of the circuit board 1, the short It does not cause such problems. Then, the conductive contact portion 8B of the switch spring 8 contacts the positive electrode pattern 1C with a desired spring pressure to supply power to the electronic components 2, 3, and 4, and the conductive contact portion 8B contacts the electrode of the liquid crystal panel 5, especially in the illustration. Since it is close to the back side of the opposite side (lower side), even if the lower side of the liquid crystal panel 5 falls down and tilts due to impact when the user is carrying it, it will not touch this conductive contact part 8B and will not disturb it further. Since tilting is prevented, the appearance does not deteriorate significantly, and there is no need for dummy rubber for tilt prevention, which was additionally used in the past, and tilt prevention can be achieved at low cost.

In addition, if some of the parts, such as the liquid crystal panel 5 or the circuit board 1, break down due to long-term use by the user, the large diameter part 7' of the heat crimping can be cut off with a cutter knife, etc., and the product can be disassembled and replaced with a new one. Simply replace it, insert the screw 11 into the screw hole 7B immediately adjacent to this dowel, and complete the assembly. By doing this, after-sales service can be easily performed, and the dealer does not need to keep a large number of expensive finished movement products in stock; they only need to have the required number of each part, and the user can All you have to do is cover the cheap repair costs.

This integrally assembled electronic timepiece movement displays a common and well-known timekeeping function on the liquid crystal panel 5 by inserting a silver battery 9. If the user wants to see the "month/day" or "seconds" display in addition to the so-called "time display," he/she can press a side button provided on the exterior. For example, by pressing the upper right side button, switch spring 8
The side button receiving portion 8D receives this and slides the switch input arm portion 8C on the circuit board 1.

There is a switch input pattern section 1D at the tip of the switch input arm section 8C, and when the switch input arm section 8C rides on this pattern, switch input is achieved, and the display changes to "month/day" display or "seconds" display. It changes. When the user releases his or her finger from the side button, the switch input arm 8C returns to its original position due to the spring force, maintains a predetermined switch stroke 1, and waits for the next input opportunity. By making the switch input pattern part 1D into a fan shape with the center on the switch input arm part 8C side, the switch stroke due to mutual positional variations between the tip of the switch input arm part 8C and the switch input pattern part 1D during processing and assembly can be reduced. There is less variation. For example, in FIG. 6, if the IE is the variation range of the tip of the switch input arm 8C with respect to the switch input pattern, even when the tip of the switch input arm 8C is around 8C', the switch input arm 8
The tip of C′ contacts the inside of the fan-shaped input pattern part 1D and input is received, but the switch input pattern shape is 1.
In the case of D′ and the case of 1D, which is the present invention, 8
Near C', a difference of l' occurs in the switch stroke, and the switch stroke of the 1D' shape is longer by l'. Although not shown, if the switch stroke becomes long, a situation may occur in which the side button receiving portion 8D of the switch spring contacts the panel frame first and no input is made. Note that the lower right switch input arm 8C is used for "time adjustment", and switch input can be achieved by the same operation as described above.

As described above, the present invention provides electrical connections between the circuit board on which electronic components such as MOSIC chips are mounted, the switch spring laminated on the circuit board, and the electrodes of the circuit board and the electrodes of the liquid crystal panel placed on the switch spring. The switch spring includes a connector for connecting the liquid crystal panel to a predetermined position on the circuit board, and a panel frame for arranging the liquid crystal panel at a predetermined position on the circuit board. A switch input arm having a stroke and contacting the circuit board with a predetermined pressing force; and a side button receiving part for sliding the switch input arm in a plane direction and electrically contacting the switch input pattern part. In addition, the switch spring is clamped and fixed between the panel frame and the circuit board, so there is no need to move the switch input arm sideways and hook it to the circuit board during assembly. There is no need to worry about the parts breaking, and since these parts can be simply stacked, automatic assembly is possible and mass production is possible. In addition, by regulating the movement of the liquid crystal panel with a part of the switch spring, there is no need for special movement regulating parts.
Moreover, it is possible to provide a liquid crystal electronic timepiece with good appearance by preventing the liquid crystal panel from tilting.
