In addition, past predicted weather is displayed together with the current weather, and the display is updated at predetermined time intervals, whereby a change in predicted weather change can be known.

Embodiment FIG. 1 shows a block diagram of a first embodiment of the present invention.
In the figure, 1 is a barometric pressure sensor as a detecting means, 2 is a display means,
Reference numeral 3 denotes a control circuit as prediction and display control means.

The pressure sensor 1 is composed of a diaphragm, a photo interrupter, an A / D converter, and the like. The surface of the diaphragm is displaced in accordance with the air pressure. A shielding plate is provided on the surface of the diaphragm, and a photo interrupter is arranged so as to sandwich the shielding plate. When the air pressure changes, the surface of the diaphragm is displaced, and the shielding plate is displaced. When the shielding plate is displaced, the amount of light from the light emitting unit to the light receiving unit of the photo interrupter changes, and the output voltage changes. The output voltage is A / D (analog / digital) converted by an A / D converter and output as atmospheric pressure data.

The control circuit 3 includes a microcomputer 4 and a RAM (random access
Memory) 5. The atmospheric pressure data from the atmospheric pressure sensor 1 is stored in the RAM 5 as needed. The microcomputer 4 predicts the weather from the change pattern of the atmospheric pressure data stored in the RAM 5 and supplies display data corresponding to the prediction to the display means 2. The display means 2 is configured to perform display according to display data from the microcomputer 4.

Next, the operation of the apparatus will be described with reference to FIG. RAM5
, New air pressure data is constantly supplied from the air pressure sensor 1 via the microcomputer 4 and stored for a certain period of time, and then the data is discarded. The atmospheric pressure data is supplied from the RAM 5 to the microcomputer 4, and the microcomputer 4 predicts the future atmospheric pressure from the change pattern of the past atmospheric pressure data from the RAM 5, and predicts the future (several hours later) from the predicted atmospheric pressure ( Step 6,
7).

When the weather is predicted, it is determined whether the predicted weather is the same as the currently displayed weather (step 8). If the predicted weather is the same as the currently displayed weather, the currently displayed weather is displayed as it is by the display means 2 in a normal display, that is, blinking for a predetermined period is continued (step 9).

At this time, when the predicted weather is different from the currently displayed weather, the display notifying that the currently displayed weather is to be changed in this embodiment flashes twice during a certain period of the normal display. The display unit 2 is caused to perform the operation for a predetermined time (steps 10 and 11). Thereafter, normal display is performed (step 9).

For example, when the prediction changes from sunny to cloudy at time t _{1 as} shown in FIG. 4 (A), the sunny lamp 12 blinks at a regular period, which is a normal display, before time t ₁ , Time t ₁
It goes out after that. Further, the lamp 13 to the display of fogging is a fourth view (B) to indicate such next prediction is turned off at time t ₁ earlier, conventional performing flashing the constant period at time t ₁ the switched prediction switching Flashing is not performed once but is performed twice in one cycle. After this certain time is displayed showing the change in the different prediction from the normal display, at time t ₂ the normal display.

The display means 2 blinks at regular intervals in the normal display, but blinks twice for a fixed time within one regular display cycle when the predicted weather does not match the displayed weather. Later, a normal display is performed. As described above, when the blinking is performed twice in one cycle of the normal display, it can be understood that the display is changed shortly.

FIG. 5 is a diagram for explaining the operation of the second embodiment. The structure is the same as that of the first embodiment, and the operation is such that the lighting time is changed according to the time after the display is changed as shown in FIG. You can see if the forecast has changed.

FIG. 6 is a diagram for explaining the operation of the third embodiment, and the configuration is the same as that of the first embodiment. As shown in FIG. 6, when the prediction is changed and the display is changed, the time after the prediction is changed can be known by increasing the number of blinks according to the time from the time when the display is changed.

FIG. 7 is a plan view and a diagram for explaining the operation of the display section of the fourth embodiment, and the configuration is the same as that of the first embodiment. As shown in FIG. 7 (A), the display means 19 is provided with a display unit 20 for displaying the past weather, and this is used as a control means to update and display the prediction at predetermined time intervals by a microcomputer or the like. As shown in FIG. 7 (B), the current forecast weather moves to the left every predetermined time. The predicted weather transition can be recognized at a glance.

In addition, as shown in FIG. 8, by displaying the previously displayed weather dimmed from the currently displayed weather, the transition of the predicted weather can be understood.

FIG. 9 is a plan view and a view for explaining the operation of the display means of the fifth embodiment. This display means is also controlled by the microcomputer 4. As shown in FIG. 9 (A), a bar graph display 16 indicating the time since the display was provided is provided in proximity to the pattern 15 for displaying the weather, and the time since the change is displayed to indicate the time. Can recognize the time since
