Abstract

PURPOSE:To make many switch inputs possible by means of a small number of switch terminal patterns by providing three switch terminal patterns at intervals of 120 deg. on a circuit substrate and providing three recessed or projecting portions 60 deg. apart on an outward rotary bezel. CONSTITUTION:Three switch terminal patterns 12a are arranged at intervals of 120 deg. on a circuit substrate 12, and the projecting portions 1a of an outward rotary bezel 1 are located on the same circumference as the switch terminal patterns 12a and three projecting portions 1a are arranged 60 deg. apart. By the combination of three switch terminal patterns 12a(1), (2), (3) of the circuit substrate 12 and three projecting portions 1a(1), (2), (3) of the bezel 1, the bezel 1 is rotated every 60 deg. so as to be made one rotation so that a switch 6 is inputted. With this arrangement, more number of switch input than the number of the switch terminal patterns can be set.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic timepiece, and more particularly to an electronic timepiece that performs a switch operation by rotating an external bezel.

[Conventional technology]

Conventionally, there are two types of switch input mechanisms for electronic watches: one is to input a switch by pressing a button placed on the side of the watch, and the other is to input a switch by pressing a button placed on the front side of the watch.

[Problem to be solved by the invention]

The downside to the above example is that there are multiple buttons on the side of the watch, making it difficult to identify which button they are, and how many times to press them to bring up the mode you want. This gave the impression that the overall operation of the watch was difficult to understand.

In addition, in the case of the buttons placed on the front, there are 1 buttons per 1 mode called direct call, which is very easy to operate when incorporating a small number of modes, but when it comes to multi-functions, the number of buttons increases. However, there is a limit to how many buttons can be added within a limited space, and it has the drawback that more than a certain number of modes cannot be arranged.

[Means to solve the problem]

In order to eliminate the above-mentioned drawbacks, the present invention provides a concave or convex portion on the external rotating bezel of the exterior part, and a plurality of switch terminal patterns on the circuit board at regular intervals, so that the external rotating bezel can be rotated. The number of switch inputs exceeds the number of switch terminal patterns. That is, the purpose is to enable a large number of switch inputs with a small number of switch terminal patterns.

〔Example〕

Next, one embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a plan view of one embodiment of the present invention. 1 is an external rotating bezel, 2 is an external body, 3 is a button provided on the side of the exterior, 4 is a display section of the clock, and 20 is a positioning mark for each mode. There are 6 names 21 for each mode on the external rotating bezel I.
A mode setting mark 22 is displayed. The figure shows that the current mode is rALARMIJ.

FIG. 2 is a sectional view of one embodiment of the present invention. The external rotating bezel 1 is pressed against the exterior body 2 by a gasket 6. The gasket 6 is for generating torque when rotating the bezel.

The module is made of glass5. Lid pig 8. Packets 15, 16 arranged respectively on the mode changeover switch button 7.
It is arranged on the exterior of waterproof structure according to 17. In the external rotating bezel 1, a plurality of convex portions 1a are provided on the lower surface facing the body 2. By rotating the external rotating bezel 1, the convex portion moves. A plurality of switch input means are provided on the watch body corresponding to this portion. In this embodiment, the switch input means includes a mode changeover switch button 7, a mode changeover switch plate 9, and a switch terminal pattern 12a. The mode changeover switch button 7 is pressed by the convex part 1a of the outer rotating bezel, pushes the mode changeover switch plate 9 toward the circuit board 12, and comes into contact with the switch terminal pattern 12a arranged on the top surface of the circuit board 12. Then, the mode changeover switch is input.

The mode changeover switch plate 9 is a component of the battery frame 109, the circuit board 12°, and the panel frame 11, and is fixed by tightening the screws 13 in a sandwiched manner. The mode changeover switch board 9 is a circuit board pattern■. on top of screw 1
It is designed to make contact by closing 3. When the la portion of the external rotating bezel is a concave portion, the mode changeover switch button 7 is pushed upward by the repulsive force of the changeover switch plate 9.
Mode changeover switch plate 9 and switch terminal pattern 12a
contact will be terminated.

In this embodiment, the switch input is performed when the rotating bezel portion 1a is a convex portion, but when the switch terminal pattern 12a is arranged on the bottom surface of the circuit board 12,
It is also possible to make the switch input when the portion 1a of the rotating bezel is a recessed portion. The switch input means is connected to means for outputting signals corresponding to the combination of inputs of the switch input means.

FIG. 3 is a layout diagram of the switch terminal patterns 12a of the circuit board 12 according to an embodiment of the present invention, in which four switch terminal patterns 12a are arranged at 90 degree intervals.

FIG. 4 is a plan view of an external rotating bezel according to an embodiment of the present invention. The positions of the convex portions 1a are on the same circumference as the switch terminal pattern 12a, and three convex portions are arranged at intervals of 120 degrees.

FIG. 5 is a switch input circuit diagram of an embodiment of the present invention. Switch terminal pattern 12a (IL

If you rotate it once by 60 degrees, you will get 8 switch inputs.

In the case of 101 inputs, the switch terminal pattern 12a (1

31 is not located at a position corresponding to the convex portion 1a of the rotating bezel 1,
Since there is no switch input, the inverter 201 connects from OFF to ON during the connection to the AND circuit 202, and the AND circuit 202 is manually operated. Therefore, AND circuit 2
In the case of 02, three input terminals are turned on circuit-wise, and a signal is generated. An example is shown below in which eight switch inputs can be made by rotating the external rotating bezel 1 by 60 degrees.

〔Effect of the invention〕

As described above, the present invention has the effect of allowing the number of switch inputs to be greater than the number of switch terminal patterns by providing a plurality of switch terminal patterns on the circuit board and a convex portion or a concave portion on the externally rotating bezel. There is. It also has the effect of being easily incorporated into multi-functional specifications.
