Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an electronic thermometer that displays measured temperatures such as body temperature numerically, and further stores temperature data and displays them as a graph.

(B) Conventional Technology As disclosed in JP-A-60-215347, a conventional electronic thermometer of this type is an electronic thermometer that measures body temperature, stores the data of the body temperature, and displays it as a graph in a display window. Thermometers are known.

(C) Problems to be solved by the invention However, in the above-mentioned conventional electronic thermometer, the display of the body temperature is provided with a resolution of 0.1 ° C. or less in order to ensure accuracy, but it is displayed as a graph from the performance of the display device. In many cases, the scale can be only 0.1 ℃ or higher. In addition, if you want the body temperature displayed as a graph to be displayed numerically with a resolution of less than 0.1 ° C, that was not possible. In addition, the body temperature was sometimes mistakenly read in the graph display.

The present invention has been made in view of the above-mentioned problems of the conventional art, and provides an electronic thermometer that displays a temperature displayed as a graph with a numerical value having a higher resolution than this.

(D) Means for Solving the Problems In an electronic thermometer equipped with a storage device for storing data of measured temperature and a display device for displaying the temperature, a graph is displayed on the display device. A cursor that indicates each temperature and that can be moved to a place where the user indicates an arbitrary temperature, and a switch that the user can arbitrarily operate, and the temperature indicated by the cursor when the user operates the switch Is read from the storage device and the temperature is displayed on the display device with a numerical value having a higher resolution than the graph.

(E) Action When the user moves the cursor indicating any temperature displayed in the graph on the display device and operates the switch, the numerical value with higher resolution than the graph is displayed on the display device.

(F) Embodiment One embodiment of the present invention will be described below with reference to the drawings. Figure 1,
FIG. 2 is an explanatory diagram of a liquid crystal display as a display device, FIG. 1 is an explanatory diagram when the body temperature is displayed in a graph, and FIG. 2 is an explanatory diagram when the body temperature is represented by a numerical value. (1) is a liquid crystal display capable of displaying graphs and numbers by turning on and off many dots (2), and (3) is a cursor for pointing to arbitrary body temperature data by a user's operation. As shown in FIG. 2, the electronic thermometer as one embodiment of the electronic thermometer of the present invention is different from the graph display in that the liquid crystal display (1) shows the month and day and the hour and minute on the upper stage, and the body temperature and temperature on the lower stage. Several types of display are possible.

FIG. 3 is a block diagram of an electronic thermometer shown as an embodiment of the electronic thermometer of the present invention. Reference numeral (4) is a temperature sensitive element for measuring body temperature and air temperature, and the resistance changes depending on the temperature, which changes the oscillation frequency of the oscillation circuit (5). (6)
Is a 1-chip 4-bit microcomputer which is generally commercially available. The microcomputer (6) internally has a RAM (7) as a storage device for storing date and body temperature data and a CUP (9) for performing arithmetic processing according to a program stored in a ROM (8). ) And. (10) is a memory switch, which is closed by the user after the temperature is detected in order to store the date and body temperature data in the RAM (7) and read the graph data as numerical values. (11) and (12) are a start switch and a graph switch, respectively. The user closes the start switch (11) at the time of starting temperature measurement or moving the cursor (3) to display a graph. The user closes the graph switch (12) when switching between displaying numbers. Here, if the start switch (11) is closed when the body temperature or the air temperature is displayed numerically on the liquid crystal display (1), the temperature measurement is started. Moreover, when the signals from the respective switches (10), (11) and (12) are input to the CPU (9) in the microcomputer (6), the ROM
According to the program of (8), the CPU (9) performs arithmetic processing, that is, outputs signals to the LCD driver (15) to change the display of the liquid crystal display (1), and stores the data in RAM.
Processing such as storing in (7) is performed. (13) is a buzzer, and a timer (14) is used at the end of temperature measurement or when notifying the set time.
It sounds by the signal from. Reference numeral (15) is an LCD driver provided for turning on or off the dots (2) of the liquid crystal display (1) according to a signal from the microcomputer (6).

FIG. 4 is an external view of an electronic thermometer shown as an embodiment of the electronic thermometer of the present invention.

(16) is a stopper provided on the back side of the tongue for fixing with a tooth during temperature measurement.

The configuration of the present invention is as described above, and the operation will be described below. The temperature sensing element (4) is applied to the back side of the tongue, the stopper (16) is fixed with teeth, and the start switch (11) is closed to start temperature measurement. After the end of this temperature measurement, the buzzer (13) sounds, and when the memory switch (10) is closed after that, the date and body temperature data are stored in the RAM (7). Further, when the graph switch (12) is closed, the body temperature stored in the RAM (7) is displayed in a bar graph on the liquid crystal display (1) as shown in FIG. At this time, the start switch (11) is closed an appropriate number of times, the cursor (3) is moved to the desired body temperature, and the memory switch (10) is closed, rather than the graph display as shown in FIG. The body temperature is displayed numerically along with the date with higher resolution. The above-mentioned FIG. 2 shows that the upper row was the date and the lower row was the body temperature, that is, the body temperature on July 15 was 36.53 ° C.

The present invention is not limited to the electronic thermometer shown in the above-mentioned embodiment, but can be applied to various thermometers other than the thermometer.

(G) Effect of the Invention The present invention is as described above, and the user arbitrarily moves the cursors indicating the respective temperatures displayed in the graph on the display device, and the temperature indicated by the cursor is further increased than the display of the graph. Since the numbers are displayed with high resolution, more accurate temperature values can be read. Further, since the temperature displayed in the graph can be displayed in the numerical value, it is possible to prevent the user from misreading the temperature displayed in the graph.
