BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic timepiece, and more particularly to a plurality of functioning electronic timepieces having a rotary switch when using an abduction bezel.

[0002]

2. Description of the Related Art Conventionally, the switch input function of an electronic timepiece has been
A structure for performing switch input by pressing a button arranged on the side surface of the timepiece and a structure for performing switch input by pressing a button arranged on the front surface of the timepiece have been known. Further, a structure for establishing electrical connection with a switch pin by a protrusion provided on an abduction bezel and a switch structure for combining contact patterns and contact pieces at regular intervals have been known. For example, Japanese Utility Model Laid-Open No. 54-20175 and Japanese Patent Laid-Open No. 50-63971 disclose conventional switch structures.

[0003]

However, in the conventional electronic timepiece, it is difficult to identify the function of the plurality of buttons on the side surface of the timepiece, and it is difficult to identify the mode desired by the user. There was a problem that it was difficult to know whether to press the button twice. In addition, the buttons arranged on the front of the watch have one button for each mode, and there is a structure in which the switch pin conducts electricity from the protrusion of the abduction bezel, or a switch structure that combines contact patterns at regular intervals and contacts. Also, 1 for each mode
Since one switch pin and one switch pattern are required, it is necessary to provide many switch buttons, switch pins, and switch patterns when a large number of switch inputs are required, which causes a problem that the timepiece becomes large.

Further, even in the structure in which the switch pin is electrically connected to the switch pin by the protrusion, the switch pin is directly connected to the wiring, so that it is difficult to secure the waterproof performance and the impact resistance of the switch pin. However, there is a problem that it is difficult to maintain the reliability of the switch operation. Therefore, an object of the present invention is to have an abduction bezel capable of inputting a large number of switches with a small number of switch terminal patterns in order to solve such a problem in the related art, and the switch part has good waterproofness and impact resistance. I am going to get an electronic watch.

[0005]

In order to solve the above problems, the present invention has a structure in which the outer bezel of the exterior part has a concave portion or a convex portion provided at a constant angle, and the circuit board has four
A structure having a switch terminal pattern of 90 degrees at intervals, a switch lead member having an elastically deformable lead portion at a position corresponding to the switch terminal pattern portion, and contact the switch lead member via an elastic force, Via a plurality of changeover switch members operable in a direction substantially parallel to the rotation axis of the outer rotation bezel, a packing member that operably supports the changeover switch member, and a bezel holding packing that rotatably supports the outer rotation bezel. It is configured to have a body for supporting it and a switch operation detecting means.

[0006]

In the electronic timepiece constructed as described above,
The rotation or rotation of the abduction bezel causes the depression or projection of the abduction bezel to rotate, and the changeover switch member that comes into contact therewith vertically moves due to the elastic force of the switch lead member. Since the changeover switch member is supported via the packing member, water does not enter from this packing portion. When the change-over switch member moves downward, the change-over lead member also deforms downward and the conduction state with the circuit board changes, so that the output signal to the detection means wired in the pattern of the circuit board changes and the rotary bezel is changed. It becomes possible to input a plurality of switches corresponding to the rotation of a certain angle.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of an embodiment of the present invention. The abduction bezel 1 is rotatably incorporated in the outer case 2.
A button 3 is provided on the side surface of the exterior, and a display portion 4 of the timepiece and an alignment mark 20 for each mode are further provided on the surface.
The abduction bezel 1 has a name 21 of each mode 8 and a mode alignment mark 22. FIG. 1 shows that the current mode is “A LARMI”.

FIG. 2 is a sectional view of an embodiment of the present invention.
The abduction bezel 1 is pressed against the outer case 2 by a packing 6. The packing 6 is for generating torque when rotating the bezel. The module is arranged on the exterior of a waterproof structure by packings 15, 16 and 17 arranged on the glass 5, the back cover 8 and the mode changeover switch button 7, respectively. In the abduction bezel 1, a plurality of convex portions 1a are provided on the lower surface facing the body 2. By rotating the abduction bezel 1, the convex portion moves. Corresponding to this portion, the timepiece body is provided with a plurality of switch input means.
In the present embodiment, the switch input means is composed of the mode changeover switch button 7, the mode changeover switch plate 9 and the switch terminal pattern 12a. The mode changeover switch button 7 is pushed by the convex portion of the 1a portion of the abduction bezel, pushes the mode changeover switch plate 9 toward the circuit board 12, and contacts the switch terminal pattern 12a arranged on the upper surface of the circuit board 12. Then, the mode change switch is input. The mode changeover switch plate 9 includes a battery frame 10, a circuit board 12, and a panel frame.
The 11 components are fixed in a sandwich by tightening the screws 13. The mode changeover switch plate 9 is located on the pattern V _DD of the circuit board and is brought into contact with the screw 13 by tightening the screw 13. When the portion 1a of the outer rotation bezel is a recess, the mode changeover switch button 7 is pushed upward by the repulsive force of the changeover switch plate 9, and the contact between the mode changeover switch plate 9 and the switch terminal pattern 12a is released.

In this embodiment, when the rotary bezel 1a is a convex portion, the switch input is made. However, when the switch terminal pattern 12a is arranged on the lower surface of the circuit board 12, the rotary bezel 1a is provided. It is also possible to switch input when the portion is a concave portion. The switch input means is connected to the means for outputting a signal corresponding to the combination of inputs of the switch input means.

FIG. 3 is a layout view of the switch terminal patterns 12a of the circuit board 12 according to one embodiment of the present invention, in which four switch terminal patterns 12a are arranged at intervals of 90 degrees. FIG. 4 is a plan view of an abduction bezel according to an embodiment of the present invention.
The position of the convex portion 1a is on the same circumference as the switch terminal pattern 12a, and only five and one at every 30 degrees are arranged from the fifth to 60 degrees.

FIG. 5 is a switch input circuit diagram of an embodiment of the present invention. Switch terminal pattern 12a on the circuit board 12
Four of (1), (2), (3), (4) and the convex portion 1a of the abduction bezel 1,
With the combination of (2), (3), (4), (5), and (6), the abduction bezel 1
Rotate every 30 degrees to make one rotation, which results in 12 switch inputs. For 101 input, switch terminal pattern 12a
(1) and the convex portion 1a (3) of the abduction bezel 1 correspond to each other, switch input is performed, the switch is turned on, and the AND circuit 202 is connected. The other switch terminal patterns 12a (2), (3), (4) are the rotating bezel 1
Since it is not in the position corresponding to the convex portion 1a of the inverter and the switch is not input, the inverter 201
Connect from OFF to ON with and input to AND circuit 202. Therefore, in the AND circuit 202, the four input terminals are turned on in a circuit manner and generate a signal. An example in which 12 switch inputs can be obtained by rotating the abduction bezel 1 by 30 degrees is shown below.

Therefore, it is possible to input a larger number of switches than the number of switch patterns by rotating the outer bezel at a constant angle. Further, since the operation of the abduction bezel is transmitted to the switch pattern of the circuit board via the changeover switch member and the switch lead member having elasticity, the switch reed member is relaxed even if a large impact force is applied to the abduction bezel from the outside. So
The circuit board and the changeover switch member can be prevented from being damaged, and the shock resistance of the watch can be secured.

Further, since the changeover switch member is held through the packing, the force for operation is stable and the waterproof property is secured.
