Abstract

PURPOSE:To obtain a compact constitution, by shifting a temperature display point in the axial direction of elapsed days, thereby reducing the width in the lateral direction of a display surface. CONSTITUTION:By closing a switch 6, a body temperature measuring and specifying part 5 is operated, and a CPU3 sends a signal corresponding to the output of a temperature sensor 1 to a memory part 7 for storing the signal. The signal is displayed on a display part 10 at the same time. When the switch 6 is turned OFF, the display goes out, but the memory in the memory part 7 is maintained. At every measurement, the temperature is sequentially displayed as a graph in accordance with the elapse of the days. When the measurements have been performed for 15 days, the graph is all filled up. At the measurement on 16th day, all the display points are shifted to the left by one day. The temperature at that day are displayed on the right end. In an elapsed day display 22, one day is increased, and the corresponding day is displayed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a thermometer having an electro-optical display, particularly suitable as a women's thermometer.

For example, it is necessary to record the temperature of a woman or a patient over a long period of time. In a device that displays temperature records using an electro-optical display device, the horizontal axis displays elapsed days and the vertical axis displays temperature, but this requires a considerable length in both the vertical and horizontal directions, and the display screen is inevitably becomes large, making it inconvenient for mobile phones.

Therefore, an object of the present invention is to provide a device that can perform necessary recordings with a small display surface and can be used as a compact thermometer.

In accordance with this objective, the thermometer according to the present invention includes a display surface having a temperature chart having a temperature display axis and an elapsed date display axis, a temperature sensor that converts body temperature into an electrical signal, a storage section that stores the body temperature signal, and a temperature sensor that converts body temperature into an electrical signal. An electro-optical display device that displays the stored contents of the memory section in a point display or a bar shape in a temperature chart, a device that moves the display in the chart sequentially according to the elapsed date, and a device that displays the contents of the chart by moving it sequentially according to the elapsed date. and a device that displays the temperature of the next day by shifting the entire display in the chart in the direction of the elapsed date display axis.

The present invention will be described in detail below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a temperature sensor for measuring body temperature, such as a thermistor, and its output is given to the CPU 3 via an AD converter 2. The CPU 3 is supplied with clock pulses from the oscillation circuit 4, and the body temperature measurement instruction section 5 is connected to the CPU'U3 via the switch 6. By closing the switch 6, the CPU 3 receives the number of pulses output from the temperature sensor 1. It is counted and the result is sent to the storage section 7 and stored there.

The stored contents are sent to the display driver 8 via the CPU 5, and the body temperature is displayed on the display section 10 using the liquid crystal display device.
It is arranged to be displayed in the table shown in the figure.

A display changeover switch 11 is connected to CPtJ, and by operating this switch, all display points 12 on the display section can be shifted to confession in the horizontal axis direction indicating the number of elapsed days. Furthermore, the CPU 3 is provided with a time, date, and alarm device, and outputs display signals such as these. The time and date are displayed and corrected in the time display window 14 and date display window 15 shown in FIG. 2 by operating the time and date switch 16. Alarm time setting switch 1
6, and the buzzer 17 is activated to issue an alarm.

On the other hand, a beam set switch 18 is connected to the storage section 7 so that it can be reset.

As shown in FIG. 2, a glass 20 is provided on the front surface of the display section, and vertical and horizontal lines 21 for temperature display are printed on it.
An elapsed date display 22 indicating the number of elapsed days is displayed on the upper part by a liquid crystal display device, while an @ degree display 24 is printed along the vertical axis.

In Figure 2, the left end shows the first day and month, and the rsJ
rloJ [sco day is displayed.

The figure shows a state in which the temperature by mouth weight from the first day to the 15th day is stored and displayed, and the temperature is displayed as a temperature display point 12 by a liquid crystal display device at the intersection of vertical and horizontal lines 21.

Next, to explain the operation, by closing the switch 6, the body temperature measurement instruction section 5 is activated, and the CPU 6 sends a signal corresponding to the output of the temperature sensor 1 to the storage section 7 to store it, and at the same time displays the temperature on the display section 1o. is displayed as a display point at the first date and month on the left side of the chart. When the switch 6 is turned off, the display disappears, but the memory in the storage section 7 is retained. When the switch 6 is turned on at the time of measurement on the next day, the temperature of that day is displayed on the display section 10 at the position of the corresponding day next to the display point of the previous day.

In this way, each time the temperature is measured, the temperature is displayed as a chart in sequence as the day progresses. If you measure for 15 days, the entire chart will be filled in, and if you measure on the 16th at 8, all the display points will be shifted to the left by one day, and as shown in Figure 3, the temperature for that day will be displayed on the right edge, and at the same time the elapsed date will be displayed at the top. The display 22 increases by one day and displays the corresponding day.

The movement of the display point in the direction of the elapsed date display axis, the shift of all display points to the left, and the operation of switching the date display are not performed by operating the switch 6, but are performed by the clock device in the CPU 5 when 24 hours have elapsed. Alternatively, the movement, shift, and display switching may be performed automatically after 15 days have passed.

Furthermore, by operating the display changeover switch 11, the temperature display point and date display can be shifted to either the left or right direction, and past temperatures can also be displayed.

Further, by operating the time and date switch 1, the entire display screen can be switched to display the time and date as shown in FIG.

As is clear from the above, in the device according to the present invention, since the temperature display point is shifted in the direction of the elapsed date axis, the lateral width of the display surface can be reduced, and therefore a compact thermometer can be constructed. .
