Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a weather display device that measures a current atmospheric pressure using a sensor such as a barometer and displays a warning of future weather by a signal from the sensor.

[0002]

[Prior art]

 Today, measure the current atmospheric pressure using a barometer, and output a predetermined measurement signal based on this measurement value, or output a predetermined measurement signal based on the measurement value and the change in the measurement value. A device that turns on the light emitting diode provided at the position of each weather mark such as a sunny mark, a cloudy mark, a rain mark and the like displayed on the display unit based on this measurement signal, and displays the weather in advance after several hours, A display device that uses a rotatable pointer instead of the light-emitting diode display and controls the rotation of the pointer based on the measurement signal to indicate each weather mark by the pointer, thereby giving a warning of the weather after several hours. (For example, Japanese Patent Publication No. 3-197894).

[0003]

[Problems to be solved by the device]

 As described above, in the display device that lights the light emitting diode provided at each weather mark position, the light emitting diode is constantly supplied with power to be lighted, resulting in large power consumption, and the power is supplied by the battery. Some devices have the drawback of shortening battery life.

Further, the display device which drives the pointer to indicate each weather mark by the pointer moves the pointer only when the weather changes, and operates so as to drive the pointer only for a short time every required time. Therefore, it is possible to reduce the power consumption per unit time and extend the battery life, but if an appropriate interval is provided between the marks to make it easier to identify each weather mark, the length of the pointer will be longer. When the weather indicator is combined with other devices such as a clock, it is necessary to increase the driving range of the pointer, and when the weather indicator is combined with other devices such as a clock, the weather indicator should be arranged to display the expected weather. There was a drawback that the placement of the pointer and the placement of the display part were limited.

[0005]

[Means for Solving the Problems]

 The present invention provides a weather display device for measuring the atmospheric pressure and displaying a notice of the weather, providing weather marks such as fine weather, cloudy weather, rain, etc., and setting a rotary axis of a pointer for indicating the weather marks to be coaxial. Alternatively, both rotary shafts should be placed close to each other and two pointers should be provided.

Further, when each weather mark and two pointers are arranged coaxially or close to each other in the rotation axis, and when each pointer indicates a position other than the weather mark, a shielding plate for hiding the pointers located at this position May be further provided.

[0007]

[Work]

 Since the weather display device according to the present invention has two pointers, it is possible to form a discontinuous portion as a driving range of the pointers, that is, a location where the weather mark is arranged. Therefore, when the weather display device is incorporated in a part of another device, the writing positions of the weather mark can be dispersed.

Further, by providing a shield plate, of the two pointers, a pointer indicating an unnecessary position that does not indicate a weather mark is located behind the shield plate so that the pointer at this time cannot be seen from the outside. be able to.

【Example】

 In the embodiment of the weather display device according to the present invention, as shown in FIG. 1, an opaque portion 12 is formed on the front plate 19 of the weather display device 10 by arranging two fan-shaped transparent portions 11 symmetrically. A weather mark is arranged according to the position of the transparent parts 11, and two rotating shafts are coaxially provided at the central positions of both transparent parts 11, and the pointers are attached to the rotating shafts respectively, and the two pointers 15 and 16 are provided. The display device 10 has the following.

In some cases, without providing the opaque portion 12, the rotation axes of the two pointers 15 and 16 may be coaxial, and the weather mark may be arranged within the driving range of the pointers 15 and 16. When forming the opaque portion 12 provided so that the two transparent portions 11 are arranged, the shield plate 13 is provided inside the front plate 19 separately from the front plate 19 as shown in FIG. In some cases, a part of the front plate 19 of the display device 10 may be used as the shielding plate 13 by applying paint to the inner surface of the front plate 19 to form the opaque portion 12. When the air display device 10 is combined with a watch body, two fan-shaped through holes are provided in the dial of the watch, and the through holes are made to correspond to the transparent portions 11 and a part of the dial is used as the shield plate 13. Sometimes.

As shown in FIG. 3, the drive control circuit of the pointer is provided with a sensor 21 such as a barometer or an atmospheric pressure change detector, and the output from the sensor 21 is input to the discrimination circuit 25 to discriminate. If the atmospheric pressure detected by the sensor 21 by the circuit 25 is equal to or higher than a predetermined value, it is clear, if it is less than another predetermined value less than the predetermined value, it is rain, and if it is between these two predetermined values, it is a cloudy measurement signal. The measurement signal is output from the circuit 25 and is input to the pointer target angle determination circuit 27.

The determination circuit 25 outputs a measurement signal based on the input from the sensor 21 every 30 minutes or every one hour, for example, by a trigger signal from the timer circuit 23. The pointer target angle determination circuit 27 outputs an angle signal to the first needle target position storage circuit 31 and the second needle target position storage circuit 41 based on the measurement signal from the determination circuit 25. According to the angle signal from the pointer target angle determination circuit 27, for example, when the measurement signal is fine or when it is cloudy when the air pressure is rising, the first needle target position storage circuit 31 sets the pointer as the pointer position on the first pointer 15 with a clear mark or cloudy weather. The first target position signal indicating the rotational position of the rotary shaft for indicating the mark is output, and the second needle target position storage circuit 41 outputs the second target position signal for positioning the second pointer 16 to the standby position. It is output to the coincidence determination circuit 42.

The standby position is a position deviated from the weather mark, and is a position on the back side of the shield plate 13 when the shield plate 13 is provided, and the pointer should not be seen by the shield plate 13. It is a position where If the measurement signal from the discrimination circuit 25 is rain or cloudy, the first needle target position storage circuit 31 indicates the standby position by the angle signal output from the finger target angle determination circuit 27 based on this measurement signal. A first target position signal indicating the rotational position of the rotating shaft to be output, and a second target position signal indicating the rotating position of the rotating shaft indicating the rain mark or the cloud mark from the second needle target position storage circuit 41. Is.

Then, the first target position signal from the first needle target position storage circuit 31 is input to the first match determination circuit 25, and the first match determination circuit 25 receives from the first needle display position storage circuit 33. The display position signal indicating the position currently indicated by the first pointer 15 is also input to the first match determination circuit 25, and the first match determination circuit 25 receives the first target position from the first needle target position storage circuit 31. The signal and the display position signal from the first needle display position storage circuit 33 are compared, and when the first target position signal and the display position signal do not match, a drive signal is output to the first needle drive circuit 34 to One pointer is located at a predetermined weather mark position or a standby position. Similarly, the second coincidence determination circuit 42 is also inputted with the second target position signal from the second needle target position storage circuit 41 and the display position signal from the second needle display position storage circuit 43 and outputs both signals. By comparison, if they do not match, the second needle drive circuit 44 is caused to output a drive signal.

The first needle drive circuit 34 normally or reversely rotates the first motor according to the drive signal from the first match determination circuit 32, and the second pointer drive circuit receives the second match determination circuit 42. The second motor is normally or reversely rotated by the drive signal. Therefore, the weather display device 10 measures the weather by the sensor 21 and the discrimination circuit 25 and displays the expected weather after several hours based on the measurement signal from the discrimination circuit 25, and every 30 minutes or 1 hour. Forecast the weather. If this forecast and the weather currently displayed by the 1st and 2nd pointers 15 and 16 are different, drive the pointers to move the 1st and 2nd pointers 15 and 16 While using two pointers, one pointer indicates the weather mark, the other pointer is the standby position removed from the weather mark, and when the shield plate 13 is provided, the pointer at the standby position is hidden behind the shield plate 13. The weather indicator can be displayed in the same manner as the conventional one by indicating the weather mark by using the other guide, and since the two guides are used, the movable range of both guides is different and the disposition of the weather mark is discontinuous. Marks can be arranged so that they form parts. When combining the weather display device 10 with other devices such as a time display device for a clock, the weather marks can be arranged with a certain degree of freedom, and the weather marks can be dispersed near the time display part of the clock pair. Since the marks can be arranged, there is an advantage that the weather display device 10 can be easily integrated with the timepiece body and the device such as the timepiece body can be downsized.

When the discrimination circuit 25 is activated by the trigger signal from the timer circuit 23, it is sufficient to activate the discrimination circuit 25 not only every 30 minutes or every hour but every required time. is there. In the weather display device 10 provided with the shield plate 13, one of the hands that does not indicate the weather mark is hidden behind the shield plate 13 so that only one hand is shown to indicate the weather mark, and the first mark is displayed. Since the rotating axes of the pointer 15 and the second pointer 16 are coaxial, it is possible to show all the weather marks as if they were pointing with a single pointer as before, without showing the pointers that are out of the weather mark. The weather can be read easily.

Further, in the above embodiment, the rotary axes of the two pointers are coaxial, but the rotary axes of both the first pointer 15 and the second pointer 16 are provided close to each other, and both rotary axes are also shielded by the shield plate 13. Depending on the case, it may be hidden.

[0018]

[Effect of device]

 In the weather display device according to the present invention, the pointer is driven by the motor, and the pointer is moved when the weather changes, so that the power consumption can be reduced and the life of the battery can be extended. Since it is a weather display device having two pointers, it is possible to form a discontinuous portion in the arrangement of the weather marks pointed by the pointers, and to give the mark arrangement a degree of freedom, so that it can be displayed on other display devices. This has an advantage that the weather display device can be easily combined.

Since the weather display device having the shield plate hides the pointer that is out of the mark position with the shield plate, the weather display device can have the same appearance as a conventional weather display device with one pointer. There is an advantage that the displayed weather is easy to read and the display is easy to see.
