g "," step "in the case of a pedometer) and other inputs from the operating means 1.

Reference numeral 3 denotes reading means. The reading means 3 optically reads a display device capable of electro-optically displaying a predetermined physical quantity by a numeral. Specifically, it is constituted by an optical scanner described later, and reads each measured value of the liquid crystal display section of the measuring device A as image data of characters and numerals.

Reference numeral 4 denotes a recognizing means. The recognizing means 4 reads, for example, "36.48" as an example of a thermometer, "125" or "63" as an example of a sphygmomanometer with respect to image data read by the reading means 3. As an example of a pedometer, "297
For example, a character string of numbers including a decimal point, such as “8”, is recognized, and further recognized as numerical data. The recognizing means recognizes not only the value of the physical quantity as numerical data but also a character. For example, "° C" displayed as a unit of temperature of a thermometer, "mmHg" displayed as a unit of pressure of a sphygmomanometer, and "step" as an example of a unit of the number of steps of a pedometer are also recognized.

Reference numeral 5 denotes a discriminating means. The discriminating means 5 discriminates a type corresponding to the read physical quantity from a plurality of predetermined physical quantity types based on the image data. In the present embodiment, the objects to be read by the display reading device B are limited to three types: a thermometer, a sphygmomanometer, and a pedometer, and the discriminating means 5 is a character included in each measuring device recognized by the recognizing means 4. Based on the character pattern indicating the unit of the physical quantity indicated by, the read physical quantity is "° C" (body temperature), "mmH
It is determined which of the three units of “g” (blood pressure) and “step” (the number of steps) corresponds. For example, if the recognized character pattern includes the character string “° C”, the unit is determined to be “° C” (body temperature), and if the character string “mmHg” is included, the unit is “mmHg”.

Reference numeral 10 is a unit setting means. For example, when the unit could not be determined, or when the determination was made and the confirmation was made, the reading of the thermometer display was erroneously determined as the blood pressure. In this case, the predetermined unit input from the operating means 1 was input. Then, the unit setting means 10 associates the numerical data recognized by the recognition means 4 with the input unit. The input unit is prioritized and associated with the result of the determination by the determination means 5. When the discrimination is made by the discriminating means 5, the unit is displayed on the display means 9 and the operation control means 2 receives a signal indicating that the discrimination has been made.

Then, the relative position between the liquid crystal display unit and the sensor pixel row is moved in the sub-scanning direction, and the transmission of data in the main scanning direction is repeated.
The dimensional pixel information is converted into a time-series electric signal. A portable hand scanner may be used as the optical scanner. Each unit shown in FIG. 1 that constitutes the display reading device B is housed in, for example, a box-shaped case (not shown). The operating means 1, the display means 9, and the reading means 3 are arranged on the upper surface of the case.

FIG. 3 shows a sphygmomanometer measurement value in a columnar form as an example of a graph displayed by the above-mentioned display means. In FIG. 3, the vertical axis indicates the blood pressure value (mmHg), the horizontal axis indicates the measurement date (month / day), and the systolic blood pressure and the diastolic blood pressure above and below the column for each measurement day, which are arranged in chronological order. It is. The user can easily know the change in his / her own blood pressure value just by looking at the graph, which is useful for health management.

FIG. 4 is a flowchart for explaining the operation of the display reading device. This will be described with reference to the block diagram and the flowchart shown in FIG.

First, a device to be read is set in ST1. The measuring device A, for example, the measured value A1 is “36.8”
The thermometer indicating “4 ° C.” is set at a predetermined position on the transparent plate on which the document of the reading means 3 (scanner) is placed, with the display unit facing down.

Next, a reading start button is pressed in ST2. Reading is started by pressing a reading start button provided on the operation means 1. Operation means 1
Is sent to the operation control means 2 and the operation control means 2
Sends a reading operation start signal to the reading means 3. S
At T3, the reading means performs a reading operation. Numerical data displayed on the liquid crystal display unit, for example, a thermometer measurement value, "3
6.84 ° C ”.

In ST4, the recognition means 4 performs a character / numerical value recognition process on the image data read by the reading means 3. For example, numerical data “36.84” and “°
C ".

After the recognizing process by the recognizing means 4, it is determined in ST5 whether the numerical value has been recognized. If the numerical value cannot be recognized, a warning display signal is sent from the recognition means 4 to the display control means 8 to give a warning.

Next, in ST6, the display control means 8 which has received the warning display signal from the recognition means 4 issues a warning display instruction to the display means 9, and the display means 9 displays, for example, "the numerical value could not be recognized". Warning message as follows.

If the recognizing means 4 has recognized the numerical value, the discriminating means 5 performs a unit discriminating process from the data recognized by the recognizing means 4 in ST7. For example, the character string "° C"
, The unit is determined to be “° C.” (body temperature).

In ST8, it is determined whether or not the determination unit 5 has determined the unit. If the unit cannot be determined,
A warning display signal is sent from the determination means 5 to the display control means 8 to give a warning.

Next, in ST9, the display control means 8 having received the warning display signal from the determination means 5 issues a warning display instruction to the display means 9, and the display means 9 displays, for example, "The unit could not be determined." Warning message as follows. That is, the display unit 9 is used as a warning unit that warns that the determination unit 5 cannot determine the type of the physical quantity.

In ST10, a display instruction is issued to the display control means 8 for the unit data determined by the determination means 5, and the display means 9 is displayed.
Indicates the unit. The user checks whether the displayed unit is correct.

When the state changes from unit input ST11 to ST10, which will be described later, the display unit 9 issues a display instruction to the display control unit 8 for the unit data input from the unit setting unit 10, and displays the input unit on the display unit 9. . The user checks whether the displayed unit is correct.

If the unit has not been determined or if the unit is incorrect, the unit is input from the operating means 1 in ST11. When a warning display or a unit confirmation display is displayed, a permission signal for unit input by the operation unit 1 is sent from the determination unit 5 to the operation control unit 2 to wait for unit input. Here, the user inputs a unit using the operation means 1. The input data is sent to the unit setting means 10 via the operation control means 2, and the unit setting means 10 rewrites the unit data of the determination means 5 to the input unit data. When the unit setting button is pressed, the unit is input in order on the display unit.
"C", the second time is displayed in units of "mmHg", and the third time is displayed in units of "step", and the unit is determined by the enter button. As described above, the operation unit 1 is an input unit for inputting the type of the physical quantity.

When the unit is determined, the data is stored in the storage means 6 in ST12 in which the numerical data from the recognizing means 4 and the unit data from the discriminating means 5 are associated with each other.

When the storage of the numerical data and the unit data is completed, the storage means 6 sends a storage end signal to the display control means 8 in ST13, and the display control means 8 displays, for example, "data stored" in the display means 9. Is displayed as in the end of storage.

When the user wants to see the graph, the user operates the graph display button of the operation means 1 as described above, and the display control means 8 displays the data which has been graphed, for example, as shown in FIG. It can be displayed on the means 9 and observed. Thus, the operation ends (ends).

FIG. 5 is a flowchart showing another determination method when a thermometer, a sphygmomanometer, and a pedometer are used. In the above-described determination method, the type of the physical quantity is determined by recognizing a character indicating the unit of the physical quantity included in the image data. However, in the determination method illustrated in FIG. Determine the type of physical quantity. FIG.
5 shows only the determination processing after the recognition processing is completed by the recognition means 4. In ST1, it is determined whether or not the recognized numerical data has a decimal point. For example, when there is a decimal point such as “36.84”, the unit is “° C.” in ST2.
(Body temperature). If there is no decimal point, ST3
Then, it is determined whether or not the number of recognized numerical data is one. For example, when the number of data is one such as “2978”, the unit is determined to be “step” (the number of steps) in ST4. If the number of data to be displayed simultaneously is two, for example, "125" and "63", the unit is determined to be "mmHg" (blood pressure) in ST5. The discrimination process is completed by the above (end)
I do. As described above, in the determination method shown in FIG. 5, the determination method based on whether the decimal point is included in the numerical data recognized by the recognition unit 4 and the number of the numerical data included in the image data read by the reading unit 3 The determination is made by combining two of the determination methods based on.

For example, when the target of the measuring device is limited to two, that is, a thermometer and a sphygmomanometer, it is possible to determine whether the numerical data includes a decimal point or by the number of numerical data. . Further, when the target of the measuring device is limited to two of the sphygmomanometer and the pedometer, it can be determined only by the number of numerical data, and when the target is limited to two of the thermometer and the pedometer, the decimal point is included in the numerical data. It is possible to determine only by whether or not.

Further, as another determination method, for example,
The target of the measuring device is limited to a thermometer and a sphygmomanometer, and the range of the displayed numerical value, for example, “32 to 42” is a thermometer (°
C), "55-280" may be determined as a sphygmomanometer (mmHg). Further, the size of the display frame of the liquid crystal display unit may be recognized and determined.

As another modified example, before reading by the scanner, the unit to be read is, for example, “°
In the case of "C", the unit is inputted from the operating means 1 beforehand, and the measured value of the thermometer is read by the scanner.
In such a case, the determination result may be completely ignored and the first input unit, "° C", may be preferentially dealt with.

Also, for a liquid crystal display device, for example, a thermometer
"X", "Y", "Z" should be displayed, "X" is data of "X", "Y" is "Y"
The data for “Z” may be displayed for personal recognition so that the device can automatically recognize the measurer, such as the data for “Z”.

Further, a fingerprint is read by an individual with a scanner to identify a person, an operation button corresponding to each individual is provided, and each person has an IC card and recognizes with the IC card. Data may be stored and managed.
