The measuring unit 6 is formed such that a sensor 20 and a computation unit 22 are accommodated in a chassis. For the sensor 20, depending on a kind of the biological information measuring apparatus 2, an electrode and the like connected to the sensor 20 may directly contact a living body. Depending on a kind of the biological information measuring apparatus 2, the operation unit 4 and the measuring unit 6 may be accommodated in the same chassis.

(1. Operation Unit)

The operation unit 4 includes the input unit 16 which is used for inputs of various pieces of information, the display unit 18 which displays the information fed from the input unit 16 and result measured by the measuring unit 6, the memory 12 in which the information to be displayed on the display unit 18 is stored, the control unit 10 which controls operations of the input unit 16, display unit 18, and memory 12, and the power supply 14. A physically-pressed button and a touch panel can be used as the input unit 16. In the case where the touch panel is used, the input unit 16 and the display unit 18 may integrally be provided.

(1.1 Memory)

Display mode data used to determine a display mode of plural items of biological information is stored in the memory 12 (corresponding to “storage unit” of the invention). The display mode data is data relating to a size or a color of characters and the data which determines display order of the plural items of biological information and display mode of the plural items of biological information. The color data is data relating to a color of characters and graphs or background color of characters. The plural items of biological information are described later.

(1.2 Display Unit)

The display unit 18 displays the biological information measured by the measuring unit 6. The display unit 18 displays the input information and the like fed from or selected by (1) the input unit 16 in addition to the measured biological information. The “biological information measured by the measuring unit 6” shall mean data in which the measured biological information (comparison result, time-series graph, point memory (result in comparison with data at a certain point), and determination result (for example, degree of obesity and achievement level of target value)). A display device such as a color liquid crystal display is used as the display unit 18.

(1.3 Control Unit)

The control unit 10 is a Central Processing Unit (CPU). The control unit 10 produces data indicating the display order of the plural items of biological information based on the fed data, and the display mode of the display unit 18 is controlled according to the display mode data. Data fed from the input unit 16 or computation unit 22 can be cited as an example of the data fed into the control unit 10.

EXAMPLES

Examples of the invention will be described below. In the following Examples, the biological information measured by the body composition meter (biological information measuring apparatus) is described by way of example. Examples will be described with reference to the configuration described in the above embodiment and FIGS. 5 to 17. The same component as the embodiment is designated by the same numeral.

Example 1

In Example 1, a processing procedure of setting the display mode of the plural items of biological information will be described in order to display the measurement result on the display unit 18 in the display mode according to a preference of the user.

FIG. 5 is a view showing the display unit 18 and input unit 16 of the operation unit 4 in the biological information measuring apparatus 2 of Example 1. FIG. 6 is a flowchart showing a procedure of setting display mode data in the biological information measuring apparatus 2 of Example 1.

In FIG. 5, the input unit 16 is used to feed the display mode data which is used to determine the display mode of the plural items of biological information. A switch button 26, a determination button 28, a display order changing mode button 30 are provided in the input unit 16.

Assuming that the plural items of biological information include “weight value”, “body fat percentage”, and “basal metabolism”, the description will be made below. The display mode data shall mean data indicating the display order of “A: weight value”, “B: body fat percentage”, and “C: basal metabolism”.

The display mode data is stored in the memory 12 such that “A: weight value”, “B: body fat percentage”, and “C: basal metabolism” are sequentially displayed as an initial setting. For example, the initial setting data of “1,A,B,C” is stored in the memory 12 in the form of the table. “1” is data indicating the number of display items, and the control unit 10 causes the display unit 18 to display the measurement result item by item. The initial setting data is data indicating that A, B, and C are displayed one by one every time the switch button 26 is pressed. When the user presses the switch button 26 while “basal metabolism” is displayed, the control unit 10 causes the display unit 18 to display “weight value”. The display unit 18 may simultaneously display “A: weight value”, “B: body fat percentage”, and “C: basal metabolism”. At this point, the control unit 10 may change the color or size of the characters or background and display the selected item such that the item is highlighted. In the case where the two items are simultaneously displayed, for example, the initial setting data becomes “2,A,B,C”.

Assuming that the initial setting data is “1,A,B,C”, the method of setting the display order will be described below.

The user turns on the power supply 14 of the biological information measuring apparatus, and the user presses the display order changing mode button 30 to set the biological information measuring apparatus at “display order changing mode” (S1). Then, the control unit 10 causes the display unit 18 to display “weight value” according to the initial setting data read from the memory 12 (S2).

When the user presses the switch button 26 once (S3), the control unit 10 causes the display unit 18 to display “body fat percentage” (S4). At this point, when the user presses the determination button 28 (S5), the control unit 10 sets “B: body fat percentage” at a priority of 1 to write “B: body fat percentage” in the table of the memory 12 (S6).

When the user presses the switch button 26 three times (S3), the control unit 10 causes the display unit 18 to display “weight value” (S4). At this point, when the user presses the determination button 28 (S5), the control unit 10 sets “A: weight value” at a priority of 2 to write “A: weight value” in the table of the memory 12 (S6).

When the user presses the switch button 26 twice (S3), the control unit 10 causes the display unit 18 to display “basal metabolism” (S4). At this point, when the user presses the determination button 28 (S5), the control unit 10 sets “C: basal metabolism” at a priority of 3 to write “C: basal metabolism” in the table of the memory 12 (S6).

When the user presses the display order changing mode button 30 (S7), the control unit 10 ends the display order changing mode, and the control unit 10 cause the display unit 18 to display the determinate display order (S8).

“1,B,A,C” which is of the display mode data is stored in the memory 12. The display mode data of “1,B,A,C” indicates that “body fat percentage”, “weight value”, and “basal metabolism” are sequentially displayed item by item.

When the measuring unit 6 measures the plural items of biological information, the control unit 10 receives the biological information measured by the measuring unit 6, the control unit 10 reads the display mode data stored in the memory 12, and the control unit 10 causes the display unit 18 to display the measured biological information in the order of the “body fat percentage”, “weight value”, and “basal metabolism” according to the display mode data.

In Example 1, the measurement result can be displayed on the display unit 18 in the display mode according to the preference of the user.

The switch button 26 and the determination button 28 are provided, so that the operation unit 4 can be formed by fewer buttons.

(Modification)

An example in which the user sets the display mode data will be described below with reference to FIGS. 7 and 8. FIG. 7 is a view showing the display unit 18 and input unit 16 of the operation unit 4 in the biological information measuring apparatus 2 of a modification of Example 1. FIG. 8 is a flowchart showing a procedure of setting display mode data in the biological information measuring apparatus 2 of the modification of Example 1.

In FIG. 7, an item-A button 32, an item-B button 34, an item-C button 36, a reset button 38, and the display order changing mode button 30 are provided in the input unit 16. The item-A button 32 is a button which selects “A: weight value”. The item-B button 34 is a button which selects “B: body fat percentage”, and the item-C button 36 is a button which selects “C: basal metabolism”.

A method of setting the display order will be described below as an example in which the initial setting data is not utilized.

The user turns on the power supply 14 of the biological information measuring apparatus, and the user presses the display order changing mode button 30 to set the biological information measuring apparatus at “display order changing mode” (S11). At this point, the control unit 10 causes the display unit 18 to display “Press button in the order in which you want the items to be displayed”.

When the user presses the item-B button 34 (S12), the control unit 10 causes the display unit 18 to display “1. body fat percentage” (S13). Then, the control unit 10 sets “B: body fat percentage” at the priority of 1 to write “B: body fat percentage” in the table of the memory 12.

When the user presses the item-A button 32 (S12), the control unit 10 causes the display unit 18 to display “2. weight” (S13). Then, the control unit 10 sets “A: weight value” at the priority of 2 to write “A: weight value” in the table of the memory 12.

When the user presses the item-C button 36 (S12), the control unit 10 causes the display unit 18 to display “3. basal metabolism” (S13). Then, the control unit 10 sets “C: basal metabolism” at the priority of 2 to write “C: basal metabolism” in the table of the memory 12. When the reset button 38 is pressed, the display of the display unit 18 returns to the initial state (no display), and the data stored in the memory 12 is erased.

When the user presses the display order changing mode button 30 (S14), the control unit 10 ends the display order changing mode, and the control unit 10 causes the display unit 18 to display the determinate display order.

When the measuring unit 6 has measured the plural items of biological information, the control unit 10 receives the biological information measured by the measuring unit 6, the control unit 10 reads the display mode data stored in the memory 12, and the control unit 10 causes the display unit 18 to display the biological information in the order of the “body fat percentage”, “weight value”, and “basal metabolism” according to the display mode data.

Therefore, the measurement result can be displayed on the display unit 18 in the display mode according to the preference of the user.

The input unit 16 includes the plural item buttons relating to the biological information which should be displayed on the display unit 18, so that the user can easily select the display mode data.

Example 2

In Example 2, a processing procedure of determining the display mode of the plural items of biological information will be described in order to display the measurement result on the display unit 18 in the display mode according to a usage characteristic (display time) of the user. FIG. 9 is a view showing the display unit 18 and input unit 16 of the operation unit 4 in the biological information measuring apparatus 2 of Example 2. FIG. 10 is a flowchart showing a procedure of determining display mode data in the biological information measuring apparatus 2 of Example 2. FIG. 11 is a view showing the display time for each item in the display unit 18 of the operation unit 4 of Example 2.

In FIG. 9, the switch button 26 is provided in the input unit 16 in order to provide an instruction for switching the display of the item of the biological information displayed on the display unit 18. The display unit 18 determines the display mode of the plural items of biological information measured by the measuring unit 6.

At this point, the plural items of biological information include “weight value”, “body fat percentage”, and “basal metabolism”. The display mode data is data which indicates the display order of “A: weight value”, “B: body fat percentage”, and “C: basal metabolism”.

The display mode data used to determine the display mode of the plural items of biological information is prestored in the memory 12. The display mode data is stored in the memory 12 such that “A: weight value”, “B: body fat percentage”, and “C: basal metabolism” are sequentially displayed as the initial setting. For example, the initial setting data of “1,A,B,C” is stored in the memory 12 in the form of the table. The initial setting data is data which indicates that “weight value”, “body fat percentage”, and “basal metabolism” are sequentially displayed one by one every time the switch button 26 is pressed. When the user presses the switch button 26 while “basal metabolism” is displayed, the control unit 10 causes the display unit 18 to display “weight value”.

After the user turns on the power supply 14 of the biological information measuring apparatus, the measuring unit 6 measures the biological information (weight value, body fat percentage, and basal metabolism) (S21), the control unit 10 causes the display unit 18 to display “weight value” measured by the measuring unit 6 according to the initial setting data read from the memory 12 (S22). While the control unit 10 causes the display unit 18 to display “weight value”, the control unit 10 starts to count a display time (corresponding to “display-related data” of the invention) (S23).

When the user presses the switch button 26 once (S24), the control unit 10 causes the display unit 18 to display “body fat percentage”. The control unit 10 ends the count of the display time, and the control unit 10 stores the time during which “weight value” is displayed in the memory 12 (S25). At this point, it is assumed that the time during which “weight value” is displayed is 30 seconds. The control unit 10 starts to count a display time during which “body fat percentage” is displayed on the display unit 18 (S23).

When the user presses the switch button 26 twice (S24), the control unit 10 causes the display unit 18 to display “basal metabolism”. The control unit 10 ends the count of the display time, and the control unit 10 stores the time during which “body fat percentage” is displayed in the memory 12 (S25). At this point, it is assumed that the time during which “body fat percentage” is displayed is one minute. The control unit 10 starts to count a display time during which “basal metabolism” is displayed on the display unit 18 (S23).

When the user presses the switch button 26 three times (S24), the control unit 10 causes the display unit 18 to display “weight value”. The control unit 10 ends the count of the display time, and the control unit 10 stores the time during which “basal metabolism” is displayed in the memory 12 (S25). At this point, it is assumed that the time during which “basal metabolism” is displayed is 45 seconds.

In the case where all the items are displayed, the control unit 10 produces the display mode data from the display time of each item, and the control unit 10 stores the display mode data in the memory 12 in the form of the table (S27). The control unit 10 determines the priority of the item to be displayed in the descending order of the display time from the display times (weight value for 30 seconds; body fat percentage for one minute; and basal metabolism for 45 seconds) stored in the memory 12. That is, the control unit 10 determines the display order of “body fat percentage”, “basal metabolism”, and “weight value”. For example, the control unit 10 produces the display mode data of “1,B,C,A” to store the display mode data of “1,B,C,A” in the memory 12. The control unit 10 controls the display mode data of the display unit 18 from the next measurement according to the stored display mode data.

In Example 2, the measurement result can be displayed on the display unit 18 in the display mode based on the usage characteristic (display time) of the user.

In Example 2, the display mode data is produced when all the items are displayed. Alternatively, the same item may be displayed plural times. In such cases, as shown in FIG. 11, the control unit 10 stores the display time of the item on the display unit 18 in the memory 12. For example, the control unit 10 may add the display time for each item when a predetermined time has elapsed since the initial display is started and produce the display mode data based on the addition result. According to this method, the usage characteristic can more correctly be reflected on the display mode.

In Example 2, the count of the display time is started from the moment it was displayed. Alternatively, the count of the display time may be started after a predetermined time has elapsed since the start of the display. Therefore, in the case of the many items, the display time of each item is not counted when the switch button 26 is continuously pressed plural times, so that the usage characteristic of the user can properly be reflected on the display mode data.

(Modification)

A processing procedure of determining the display mode data of the plural items of biological information will be described in order to display the measurement result on the display unit 18 in the display mode based on the usage characteristic (the number of display times) of the user. An example in which the display mode data is determined will be described below with reference to FIGS. 12 and 13. FIG. 12 is a view showing the display unit 18 and input unit 16 of the operation unit 4 in the biological information measuring apparatus 2 of a modification of Example 2. FIG. 13 is a flowchart showing a procedure of determining display mode data in the biological information measuring apparatus 2 of the modification of Example 2.

In FIG. 12, the item-A button 32, the item-B button 34, the item-C button 36 are provided in the input unit 16 in order to provide the instruction for switching the display of the biological information item displayed on the display unit 18. The item-A button 32 is a button which selects “A: weight value”. The item-B button 34 is a button which selects “B: body fat percentage”, and the item-C button 36 is a button which selects “C: basal metabolism”. The display unit 18 determines the display mode of the plural items of biological information measured by the measuring unit 6.

The display mode data used to determine the display mode of the plural items of biological information is prestored in the memory 12. The display mode data is stored in the memory 12 such that “A: weight value”, “B: body fat percentage”, and “C: basal metabolism” are sequentially displayed as the initial setting. For example, the initial setting data of “1,A,B,C” is stored in the memory 12 in the form of the table. When the measurement result of the measuring unit 6 is transferred to the control unit 10, the control unit 10 controls the display mode such that the displayed items are automatically switched at predetermined time intervals. When the predetermined time has elapsed since “basal metabolism” is displayed, the control unit 10 causes the display unit 18 to display “weight value”.

After the user turns on the power supply 14 of the biological information measuring apparatus, when the measuring unit 6 has measured the biological information (weight value, body fat percentage, and basal metabolism) (S31), the control unit 10 causes the display unit 18 to switch to display “weight value”, “body fat percentage”, and “basal metabolism” measured by the measuring unit 6 at predetermined time intervals according to the initial setting data read from the memory 12 (S32).

(1) When the user presses the item-B button 34 (S33), the control unit 10 adds “1” to the number of display times of the item-B button 34 to write the added number of display times in the table of the memory 12, and the control unit 10 causes the display unit 18 to display “body fat percentage” (S34 and S35). The initial value of the number of display times of each item is set at “0”.

(2) Then, when the user presses the item-A button 32 (S33), the control unit 10 adds “1” to the number of display times of the item-A button 32 to write the added number of display times in the table of the memory 12, and the control unit 10 causes the display unit 18 to display “weight value” (S34 and S35).

(3) Then, the user presses the item-B button 34 (S33), the control unit 10 adds “1” to the number of display times of the item-B button 34 to write the added number of display times in the table of the memory 12, and the control unit 10 causes the display unit 18 to display “body fat percentage” (S34 and S35).

(4) Then, when the user presses the item-C button 36 (S33), the control unit 10 adds “1” to the number of display times of the item-C button 36 to write the added number of display times in the table of the memory 12, and the control unit 10 causes the display unit 18 to display “basal metabolism” (S34 and S35). At this point, when the user further continuously presses the item-C button 36 four times, control unit 10 adds “4” to the number of display times of the item-C button 36 to write the added number of display times in the table of the memory 12, and the control unit 10 causes the display unit 18 to display “basal metabolism” (S34 and S35).

After a predetermined time has elapsed since the initial display, the control unit 10 produces the display mode data from the display time of each item, and the control unit 10 stores the display mode data in the memory 12 in the form of the table (S36 and S37). At this point, the control unit 10 determines the priority of the displayed item in the descending order of the number of display times from the numbers of display times (weight value of one time; body fat percentage of twice; and basal metabolism of five times) stored in the memory 12. That is, the control unit 10 determines the display order of “basal metabolism”, “body fat percentage”, and “weight value”. For example, the control unit 10 produces the display mode data of “1,B,C,A” to store the display mode data of “1,B,C,A” in the memory 12. The control unit 10 controls the display mode data of the display unit 18 in the order of “basal metabolism”, “body fat percentage”, and “weight value” from the next measurement according to the stored display mode data.

Therefore, the measurement result can be displayed on the display unit 18 in the display mode based on the usage characteristic (the number of display times) of the user.

Example 3

In Example 3, a processing procedure of determining the display mode data of the plural items of biological information will be described in order to display the measurement result on the display unit 18 in the display mode based on the personal attribute (such as age, sex, and body height) of the user. FIG. 14 is a view showing the display unit 18 and input unit 16 of the operation unit 4 in the biological information measuring apparatus 2 of Example 3. FIG. 15 is a flowchart showing a procedure of determining display mode data in the biological information measuring apparatus 2 of Example 3.

In FIG. 14, the switch button 26 which provides the instruction for switching the display item of the biological information displayed on the display unit 18 and a ten key 40 and a setting button 42 which are used to feed attribute data relating to the living body such as the body height, age, and sex of the user are provided in the input unit 16. The switch button 26 is used to switch the items to be displayed after the measurement or to feed the attribute data. The display unit 18 displays the plural items of biological information measured by the measuring unit 6 or the attribute data fed by the ten key 40.

In Example 3, plural pieces of display mode data used to determine the display mode of the plural items of biological information are prestored in the memory 12 in the form of the table.

For example, it is assumed that three pieces of display mode data are stored in Table 1 of the memory 12 while correlated with the age and sex.

TABLE 1

1. 20, 1, 1, 5, 4

2. 30, 2, 4, 2, 1

3. 40, 2, 6, 3, 1

TABLE 2

1. female

2. male

TABLE 3

1. weight value

2. body fat percentage

3. basal metabolism

4. skeleton muscle ratio

5. subcutaneous fat ratio

6. physical age

Table 1 is a table of the display mode data used to determine the display mode of the plural items of biological information. Table 2 is a table indicating the sex, and Table 3 is a table indicating the plural items of biological information. At this point other items of the biological information include a visceral fat level, BMI, and the like. For the body fat percentage, a total body, a body trunk, a right arm, a left arm, a right leg, and a left leg may be set at measurement and display targets. For the skeleton muscle ratio, the total body, the body trunk, the right arm, the left arm, the right leg, and the left leg may be set at the measurement and display targets.

Table 1 is a table which indicates a display mode data number, the age, the sex, and the display order from the left. The display mode data on the first line of Table 1 is data indicating that a weight value (1), a subcutaneous fat ratio (5), and a skeleton muscle ratio (4) are sequentially displayed for a female (1) in her twenties.

The following description will be made with reference to FIG. 15. The user operates the ten key 40 of the input unit 16 to feed the personal attribute data (S41). When the user presses the setting button 42 of the input unit 16, the control unit 10 encourages the user to feed the attribute data in the order of the age and the sex through the display unit 18. For example, the user feeds “25” with the ten key 40 when a message for encouraging the user to feed the “age” is displayed on the display unit 18. Then, when the user presses the switch button 26, the control unit 10 stores the age data of “25” in the memory 12, and the control unit 10 causes the display unit 18 to display a message for encouraging the user to feed “sex”. The user feeds the sex data of “1” indicating the female using the ten key 40. The control unit 10 determines the display mode data (first line) from the plural pieces of display mode data (pieces of data of first to third lines) of Table 1 based on the fed attribute data (25,1) (S42). The control unit 10 causes the display unit 18 to display the measurement result in the order of the weight value (1), subcutaneous fat ratio (5), and the skeleton muscle ratio (4) based on the fed attribute data. It is not always necessary to feed the attribute data every time the attribute data is measured, and the control unit 10 may store the determinate display mode data in the memory 12 as the data applied to the measurement result.

Then, the user performs the measurement with the biological information measuring apparatus 2. The measuring unit 6 detects the plural items of biological information using the sensor 20, and the computation unit 22 produces the measurement data relating to each item (S43). The computation unit 22 transfers the measurement data to the control unit 10. The control unit 10 rearranges the received pieces of measurement data according to the determinate display mode data, and the control unit 10 causes the display unit 18 to display “weight value” (S44 and S45). When the control unit 10 detects that the switch button 26 is pressed (S46), the control unit 10 causes the display unit 18 to display “subcutaneous fat ratio” (S47 and S45). Then, the control unit 10 detects that the switch button 26 is pressed (S46), the control unit 10 causes the display unit 18 to display “skeleton muscle ratio” (S47 and S45). The control unit 10 turns off the power supply 14 when a predetermined time has elapsed since the display start (S48). The display mode of the measurement result is not limited to the method of displaying the measurement result one by one, but the method of displaying at least two measurement results may be listed.

Thus, in Example 3, the measurement result can be displayed on the display unit 18 in the display mode based on the personal attribute (such as age, sex, and body height) of the user.

Example 4

In Example 4, a processing procedure of determining the display mode data of the plural items of biological information will be described in order to display the measurement result on the display unit 18 in the display mode based on measurement result comparison of the biological information on the user. FIG. 16 is a view showing the display unit 18 and input unit 16 of the operation unit 4 in the biological information measuring apparatus 2 of Example 4. FIG. 17 is a flowchart showing a procedure of setting display mode data in the biological information measuring apparatus 2 of Example 4.

In FIG. 16, the switch button 26 which provides the instruction for switching the display item of the biological information displayed on the display unit 18 and the ten key 40 and setting button 42 which are used to feed attribute data relating to the living body such as the body height, age, and sex of the user are provided in the input unit 16. The switch button 26 is used to switch the items to be displayed after the measurement or to feed the attribute data. The display unit 18 displays the plural items of biological information measured by the measuring unit 6 or the attribute data fed by the ten key 40.

In Example 4, Table 1 indicating target values of plural items and Table 2 indicating the sex are prestored in the memory 12.

For example, three target values (three pieces of comparison object data) are stored in Table 1 of the memory 12 while correlated with the body height and sex as follows.

TABLE 1

1. 150, 1, 45, 23, 1050

2. 155, 1, 48, 23, 1120

3. 155, 2, 51, 18, 1225

TABLE 2

1. female

2. male

TABLE 3

1. weight value

2. body fat percentage

3. basal metabolism

TABLE 4

1. red

2. blue

Table 1 is a table which indicates the display mode data number, body height, sex, plural items of target values (weight value, body fat percentage, and basal metabolism) from the left. The display mode data on the first line of Table 1 is data indicating that the weight value (45 kg), subcutaneous fat ratio (23%), basal metabolism (1050 kcal) are sequentially displayed for a female (1) having a body height of 150 cm. Tables 3 and 4 are used in producing the display mode data.

The following description will be made with reference to FIG. 17. The user operates the ten key 40 of the input unit 16 to feed the personal attribute data (S51). When the user presses the setting button 42 of the input unit 16, the control unit 10 encourages the user to feed the attribute data in the order of the body height and the sex through the display unit 18. For example, the user feeds “151” with the ten key 40 when a message for encouraging the user to feed the “body height” is displayed on the display unit 18. Then, when the user presses the switch button 26, the control unit 10 stores the body height data of “151” in the memory 12, and the control unit 10 causes the display unit 18 to display the message for encouraging the user to feed “sex”. The user feeds the sex data of “1” indicating the female using the ten key 40. The control unit 10 determines the comparison object data (first line) from the plural pieces of comparison object data (pieces of data of first to third lines) of Table 1 based on the fed attribute data (151,1) (S52). At this point, it is assumed that the target values of the plural items include the weight value of 45 kg, body fat percentage of 23%, and basal metabolism of 1050 kcal.

The control unit 10 computes how many percent of a difference between the measurement value and the target value based on the target value. The control unit 10 performs the computation for each item to obtain comparison result H. For example, the control unit 10 obtains the comparison result using the following equation (1).

H=α×{(target value−measurement value)/target value}×100}(α=1 or −1) (1)

weight value=−{(45−55)/45}×100}≅22.2(%)

body fat percentage=−{(23−26)/23}×100}≅13.0(%)

basal metabolism={(1050−980)/1050}×100≈6.6(%) (Comparison Result H)

The control unit 10 performs the computation while setting the coefficients α of the weight and body fat percentage at “−1”. The control unit 10 performs the computation while setting the coefficient α of the basal metabolism at “+1”. The coefficient α is preset for each item. The coefficient of each item is stored in the memory 12.

Using Tables 3 and 4, the control unit 10 produces the pieces of display mode data in order that the comparison results are displayed in the descending order. For example, the control unit 10 produces the display mode data of “1,1,1,2,1,3,1” to store the display mode data of “1,1,1,2,1,3,1” in the memory 12. The display mode data indicates the “the number of display items (1), weight value (1), red (1), body fat percentage (2), red (1), basal metabolism (3), and red (1)”. The control unit 10 causes the display unit 18 to display the measurement data one by one in the order of the weight value, body fat percentage, and basal metabolism. The control unit 10 performs control such that a background color of the display unit 18 is displayed in red when each item is displayed because each measurement result reaches the target value.

The control unit 10 rearranges the received pieces of measurement data according to the determined display mode data, and the control unit 10 causes the display unit 18 to display “weight value” (S55). When the control unit 10 detects that the switch button 26 is pressed (S56), the control unit 10 causes the display unit 18 to display “body fat percentage” (S57 and S55). Then, when the control unit 10 detects that the switch button 26 is pressed (S56), the control unit 10 causes the display unit 18 to display “basal metabolism” (S57 and S55). The control unit 10 turns off the power supply 14 when a predetermined time has elapsed since the display start (S58). The display mode of the measurement result is not limited to the method of displaying the measurement result one by one, but the method of displaying at least two measurement results may be listed.

In Example 4, the measurement result can be displayed on the display unit 18 in the display mode based on the measurement result comparison of the biological information on the user.

(Modification)

The target value is not limited to the ideal target value, but the measurement data measured in the past time may be used as the target value. The target value may be a statistical average value obtained from the attribute data relating to a living body. In Example 4, the personal attribute data is fed to determine the display mode. Alternatively, the user may feed the target value for each item to determine the display mode.

(Other Modifications)

In the above-described Examples, the plural items of biological information are measured by the body composition meter. However, the invention can also be applied to a pedometer and a blood-pressure meter.

In the pedometer, the number of steps, the number of steps in which the user walks with predetermined intensity or more, a time during which the user walks with predetermined intensity or more, consumed calories, a fat-burning amount, and a walking distance can be used as the plural items of biological information.

In the blood-pressure meter, a maximum blood pressure in the morning, a minimum blood pressure in the morning, a maximum blood pressure in the night time, and a minimum blood pressure in the night time can be used as the plural items of biological information.
