Description

  The present invention relates to a biometric apparatus that acquires biometric information of a user.

  In recent years, various biometric devices capable of acquiring biometric information such as a user's weight, fat percentage, bone mass, and the like have been developed and widely used. In general, the bioelectrical impedance, weight, age, gender and other biological information of the user is acquired by measurement or input, and the fat percentage and other biological information is used as an estimated value by using the acquired biological information. Some can be obtained by calculation. The biometric information acquired in this way is displayed on a display unit provided in the biometric apparatus.

  Here, there are a wide variety of types of biometric information to be acquired. Since the size of the screen of the display unit is limited, it is difficult to display the acquired biometric information at one time. If the biometric information displayed is displayed at once, it may not be easy to see for the user and may not be convenient. Therefore, in the conventional biometric apparatus, a display button corresponding to the type of biometric information is provided, for example, the fat percentage is displayed when the user presses the fat percentage button so that the obtained biometric information is displayed. A display method has been adopted in which each is displayed one by one. In addition, for example, the contents of each biological information are sequentially displayed (scroll display) in a predetermined order such as first body weight, second fat percentage, third visceral fat level, fourth basal metabolic rate, etc. ) Biometric measuring devices are also increasing.

  However, in order to provide a display button according to the type of biometric information and to be displayed when the user presses, a plurality of display buttons according to the number of types of biometric information must be provided, The biometric device becomes a complicated design in appearance. Further, when the part where the display button is provided is, for example, the upper surface portion of the main body of the biometric apparatus, every time the user views the biological information that the user wants to know, that is, every time the user operates the display button. In addition, it is necessary to take a posture to bend, and it has been forced to perform extra motion.

  On the other hand, in a biometric device that sequentially displays (scrolls) the contents of biometric information, the biometric information is displayed only in the order predetermined by the manufacturer, and the display order cannot be changed by the user. There is a problem. For example, when the biometric device is used at home, the biometric device is used by each member of the family, and the biometric information that the user wants to know may be different. Since the biometric information that the user wants to know is not displayed immediately, the user must wait until the biometric information is displayed. In addition, even for the same user, the biometric information that the user wants to know may change according to changes in the user's age, health condition, and the like.

  Therefore, the present invention has been made in view of the above-described problems, and the user himself can arbitrarily change the display order of the biological information, without forcing the user to perform extra operations for each measurement. Another object of the present invention is to provide a convenient biometric device that allows the user to immediately see the biometric information he / she wants to know. In addition, a separate display order can be set for each of a plurality of users of the biometric device, and even when the biometric information that the individual user wants to know is different, an easy-to-use biometric device is provided. The purpose is to provide.

In order to solve the above problems, in the biometric apparatus of the present invention, biometric information acquisition means for acquiring a plurality of biometric information, and biometric information display for sequentially displaying the biometric information acquired using the biometric information acquisition means and means, and display order changing means for changing the display order of the biological information in which the biometric information display means displays, input means for a user to input display order information of the biometric information desired, the said display The order information is information for specifying the biological information to be displayed first, and the display order changing means sets the display order of the specified biological information according to the display order information input by the input means. The biometric information whose display order before the specification is later than the specified biometric information is changed to the second or higher rank while maintaining the order, The biometric information whose display order was before the specified biometric information before specifying is the biometric information whose display order was after the specified biometric information before the specifying while maintaining the order. The display order after the change is changed to a display order after the change .

The biometric apparatus according to the present invention further includes storage means for storing a display order table indicating correspondence between the biometric information and the display order, and the display order changing means is the display input by the input means. According to the order information, the display order table stored in the storage means is rewritten.

In the biological measurement apparatus of the present invention, the plurality of pieces of biological information are K pieces of biological information, and the display order changing unit is specified according to the display order information input by the input unit. The display order of the information is the first, and the display order of the biometric information in which the display order before the specification is the order immediately before the specified biometric information is the Kth, and the display order is the previous two. The display order of the biometric information is set to the (K-1) th place, and the display order is similarly changed for all the biometric information .

  In the biometric apparatus of the present invention, the display order information is information for specifying a display order of all the biometric information, and the display order changing unit is configured to display the display order table according to the display order information. It is characterized by rewriting.

  In the living body measurement apparatus of the present invention, the display order information is input by long-pressing the input means while displaying the sequentially displayed biological information.

  In the biometric apparatus of the present invention, the display order information includes information for specifying biometric information to be displayed simultaneously.

  In the biometric apparatus of the present invention, the display order changing means can change the display order to be determined for each user.

  Further, in the biometric apparatus of the present invention, the biological information includes height, weight, fat percentage, visceral fat level, body water content, muscle mass, basal metabolism, bone mass, lean mass, somatic cell mass, blood pressure, It contains at least two or more of visceral fat area, BMI, obesity level, intracellular fluid volume, or extracellular fluid volume.

  According to the present invention, since the biological information display order can be arbitrarily specified and changed by the user himself, for example, the biological information that the user wants to know most is displayed first. Therefore, it is possible to provide a highly convenient biometric measuring apparatus that allows the user to immediately see the biometric information that he / she wants to know without forcing the user to perform an operation. In addition, a separate display order can be set for each of a plurality of users of the biometric device, and even when the biometric information that the individual user wants to know is different, an easy-to-use biometric device is provided. Can be provided.

  Hereinafter, as an embodiment of the present invention, a biometric device 10 when applied to a body composition meter will be described in detail with reference to the drawings. In addition, although this embodiment shows embodiment at the time of applying this invention to a body composition meter, this invention is applied also to biometric apparatuses other than a body composition meter (for example, a weight scale with a body fat scale). Is possible.

  First, the configuration of the biometric apparatus 10 according to the present embodiment will be described with reference to FIGS. 1 to 3. 1 is a perspective view showing the configuration of the biometric device 10, FIG. 2 is a block diagram showing the configuration of the biometric device 10, and FIG. 3A is a diagram showing an example of a display order table in the initial state. FIG. 3B is a diagram illustrating an example of the display order table after resetting.

  As shown in FIG. 1, the biometric device 10 includes a main body 11, a display unit 21 provided on the upper surface 11 a of the main body 11, an operation unit 22, an electrode member 32, and a foot provided on the side surface 11 b of the main body 11. Further, as shown in FIG. 2, a current supply unit 33, a voltage measurement unit 34, a weight measurement unit 35, a control unit 40, and a storage unit 41 (for example, a RAM (Random Access Memory)) are provided. ), And a body composition meter including a calculation unit 42. Below, the detailed structure of each member is demonstrated.

  The display unit 21 (biological information display unit) uses, for example, a liquid crystal display panel, and the operation unit 22 (biological information acquisition unit) includes, for example, a plurality of button switches. The display unit 21 and the operation unit 22 may be integrated using, for example, a liquid crystal panel with a touch panel function. The foot switch 23 (biological information acquisition means) only needs to be composed of a plurality of switches that can be easily operated with the foot while the user is standing, and is provided in a portion other than the side surface 11b of the main body 11 (for example, the upper surface 11a). May be. The user can input biological information (for example, height, age, and sex) by operating the operation unit 22 and / or the foot switch 23. The biometric information acquired by the input in this way is stored in the storage unit 41.

  The foot switch 23 is connected to the control unit 40, and can turn on / off the biometric device 10 by sending a signal to the control unit 40, and saves personal information and setting items in the storage unit 41 in advance. If there is, the personal information and setting items can be called up individually. For example, when the biometric apparatus 10 is used by a plurality of users (for example, when used at home), each of the plurality of foot switches 23 is assigned to each user, and the user is assigned. It is preferable that the personal information and setting items can be individually called by pressing the foot switch 23. Here, the personal information includes biological information such as the individual height, age, and sex of the user. Further, the setting items are setting items for the user to use the biometric device 10, for example, the size of characters and symbols of biometric information displayed on the display unit 21, the type of biometric information, These are the display order etc. which display the biometric information mentioned later.

  As shown in FIG. 1, the electrode member 32 includes four electrode members 32a, 32b, 32c, and 32d. When the user is placed so as to face the display unit 21 and the operation unit 22, the electrode members 32a and 32d with which the user's toes contact are energized electrodes, and the electrode members 32b and 32c with which the heel contacts are used as measurement electrodes. . A current supply unit 33 is connected to the energization electrodes 32a and 32d, and a predetermined weak constant current is supplied in accordance with an instruction signal from the control unit 40. On the other hand, the voltage measurement unit 34 is connected to the measurement electrodes 32 b and 32 c, the potential difference (voltage) at the measurement electrodes 32 b and 32 c is measured, and the measurement result is output to the control unit 40. As a result, a current flows between the toes of both feet via both legs (lower body), and a potential difference (voltage) generated in this current path can be measured between the heels. In addition to these electrode members 32, electrode members (hand electrodes, not shown) that can be held by both hands of the user can also be provided.

  A weight measuring unit 35 is provided inside the biometric apparatus 10 (FIG. 2). As the configuration of the body weight measuring unit 35, a known one can be appropriately selected. Specifically, a strain body made of a metal member that deforms according to a load when a load is applied, and a strain gauge attached to the strain body. Thus, the user's weight may be measured by a change in the resistance value corresponding to the load.

  As shown in FIG. 2, the display unit 21, the operation unit 22, the foot switch 23, the storage unit 41, and the calculation unit 42 are connected to the control unit 40, and the operation is controlled by the control unit 40. . It is preferable that the control unit 40 and the calculation unit 42 are each configured by an integrated circuit. Furthermore, the control unit 40 and the calculation unit 42 can be configured by separate integrated circuits, but a common integrated circuit may be used. Further, the control unit 40 processes data sent from the operation unit 22, the foot switch 23, the voltage measurement unit 34, and the weight measurement unit 35. Data processing is performed by the calculation unit 42 under the control of the control unit 40, and the calculation result is stored in the storage unit 41. In the storage unit 41, information necessary for data processing, a program, and a display order table described later are stored in advance.

  The control unit 40 outputs a signal instructing the amount of current to be applied to the energization electrodes 32a and 32d to the current supply unit 33, and the current supply unit 33 receiving the signal outputs a constant current to the energization electrodes 32a and 32d. It is possible. The voltage generated by the current application is measured by the voltage measuring unit 34 between the measurement electrodes 32b and 32c, and the measurement result is output to the control unit 40.

  Further, when the resistance value obtained from the load cell (not shown) of the body weight measurement unit 35 is input, the control unit 40 inputs the voltage according to the program stored in the storage unit 41 to the calculation unit 42. The bioelectric impedance of the user is calculated from the voltage value measured by the measurement unit 34 and the applied current value, and the weight is calculated from the resistance value measured by the weight measurement unit 35, and stored in the storage unit 41. Furthermore, the control unit 40 determines other biological information (for example, fat percentage) based on the biological information (height, sex, age) acquired by input and the biological information (bioelectrical impedance, weight) acquired by calculation. , Visceral fat level, body water content, muscle mass, basal metabolic rate, bone mass, lean mass, somatic cell volume, blood pressure, visceral fat area, BMI (Body Math Index), obesity, intracellular fluid volume, extracellular The calculation unit 42 is instructed to calculate (liquid amount), the calculation unit 42 calculates the biological information, and the calculation result is stored in the storage unit 41.

  The storage unit 41 stores a table (display order table) indicating correspondence between each biological information and its display order. In the display order table illustrated in FIG. 3, the total number of biological information is K. For example, in the initial state at the time of shipment (FIG. 3A), for example, from the first display order, weight, height, age, fat percentage, visceral fat level, body water content, muscle mass,. (Omitted)..., Fat free mass, somatic cell mass, built-in fat area are set in order of K.

In the present embodiment, the display order of such an initial state can be changed with the biological information arbitrarily selected by the user as the first display order. When the first biometric information is newly set, the biometric information (other than the identified biometric information) has a rank later than the biometric information (identified biometric information) set to the first place. The biological information) is sequentially lowered in order while maintaining the order of the initial state. In contrast, in the initial state, the biological information had previous rank than biometric information set to the first position (the biological information other than biometric information specified), is set to the first position The biometric information of the previous rank of the biometric information is sequentially displayed in the form of the Kth, the biometric information of the previous rank is the K-1th, and the biometric information of the previous rank is the K-2th. The ranking is reset. A specific example shown in FIG. 3B will be described below.

  FIG. 3B shows an example of the display order table after resetting. When the biological information that the user wants to display first is “fat percentage”, the rewriting of the display order is “fat percentage” in the initial state when “fat percentage” is set as the first display order. “Visceral fat level”, which was the next display order (5th), was ranked second, and “Body moisture” was the next display order (6th) after “Visceral fat level” in the initial state. The display order is changed to 3rd order so that the new display order is automatically reset. On the other hand, the biometric information (age, height, weight) that was in the display order before the “fat percentage” in the initial state is “age” that was the rank (third place) immediately before the “fat percentage”. The display order is automatically given by sequentially assigning the display order of the Kth place, the K-1st place to the "height" which was the previous order (second place), and so on. To be reset.

  The resetting of the display order as described above is performed while the biometric information is being scrolled and the biometric information desired to be the first is displayed, and the user presses a predetermined button on the operation unit 22 or the foot switch 23. This is preferable in that it can be reset by a very simple operation, but it may be reset by other methods. When the biological information desired to be first in the display order is specified by long-pressing the button or the like, the control unit 40 stores the information according to the program stored in advance in the calculation unit 42 as described above. The display order table in the unit 41 is rewritten.

  Next, the flow of changing (resetting) the display order will be described with reference to FIG. FIG. 4 is a flowchart showing a flow of resetting the display order of biometric information. In the present embodiment, as an example, acquisition of biometric information of a user related to the first biometric measurement (including acquisition by input and acquisition by calculation) is completed, and scroll display in the initial state of the biometric information is performed. In this case, the case where the resetting is performed to change the display order of the biological information in preparation for the second biological measurement will be described. It is left to the freedom of the person.

  The program is determined in advance so that the control unit 40 instructs the display unit 21 to display the Nth (N is 1 to K) biological information in the display order table of K pieces of biological information. In order to perform scroll display of biometric information, first, 1 is input as the value of N, and the value of N is stored in the storage unit 41 (step S1). Subsequently, the control unit 40 refers to the display order table and instructs the display unit 21 to display the biometric information having the first display order (“weight” in FIG. 3A) (step S2).

  In the initial state, any biological information set from the second position (“height” in FIG. 3A) to the Kth position (“built-in fat area” in FIG. 3A) is set to the first position. When setting is desired, the user waits until the desired biological information is displayed on the display unit 21 without operating the operation unit 22 (NO in step S3). In this case, the control unit 40 displays the first biological information in the display order in the initial state on the display unit 21, and then receives an operation signal output based on the user's operation for a predetermined time (for example, 3 seconds). If not, after confirming that N is not K (NO in step S5), an instruction is given to rewrite N stored in the storage unit 41 to a new incremented N (step S6). As a result, the control unit 40 displays the second living body in the display order in the initial state as the biological information (Nth biological information) having the display order corresponding to the new N in the display order table (FIG. 3A). Information (“height” in FIG. 3A) is displayed on the display unit 21 (step S2). By repeating the same processing, the user stands by without operating the operation unit 22 until the desired biological information (“Fat rate” in FIG. 3A) is displayed on the display unit 21. As a result of continuing the standby state and repeating the same processing as described above, if N reaches K (YES in step S5), it is assumed that all the biological information has been displayed. The display is terminated (step S7).

  Here, when it is desired to set the biological information displayed on the display unit 21 to the first display order (when it is desired to be displayed first), for example, desired biological information (“fat percentage” in FIG. 3A) is displayed. The biological information to be displayed first is specified by pressing the operation unit 22 or the foot switch 23 for a certain period of time (for example, 2 seconds) while being displayed on the display unit 21 (YES in step S3). When the desired biological information to be displayed first is specified by long pressing the operation unit 22 or the foot switch 23, the control unit 40 newly sets the currently displayed biological information to the first display order. In the display order table, the display order corresponding to the currently displayed biological information ("Fat rate" in FIG. 3A) (4th place in FIG. 3A) Is rewritten to the first place (step S4). Furthermore, the control unit 40 sequentially assigns a new display order to the biometric information following the biometric information set as the first place (fat rate in FIG. 3B) in the display order table (step S4). . When all the biological information has been given display ranks up to the Kth place, the display is terminated (step S7).

  By rewriting the display order table in this way, the biometric information that is initially displayed on the display unit 21 in the biometric measurement using the biometric apparatus 10 from the next time onward is specified by the user as described above. It is possible to obtain desired biological information, and it is only necessary to perform biological measurement according to a normal usage method. Therefore, the user is not forced to perform other operations, and convenience is improved.

  In the above description, immediately after the measurement of the biological information, when the acquired biological information is automatically scroll-displayed, the operation unit 22 or the foot switch 23 is operated at the desired biological information and the first place is displayed. The display order is reset. However, in the present invention, instead of this, by providing a mode that allows resetting the display order independently of the biometric measurement, it is possible to switch to this mode at any time and reset the display order. In this case, for example, the following may be performed. (1) A user activates the biometric device 10. (2) Select a mode for changing the display order table. (3) The biometric information that can be displayed on the display unit 21 is displayed as a list or scrolled. (4) The biological information to be displayed first is selected and specified by the operation unit 22 or the foot switch 23. (5) The display order table is rewritten with the first display order corresponding to the identified first displayed biometric information. (6) End the mode for changing the display order table.

  It is preferable to prepare a plurality of display order tables. This is because by preparing a plurality, it is possible to set different display order tables for each user. In this case, it is preferable to operate the foot switch 23 assigned to each user to specify the biological information that is desired to be the first display order. The display order table that is different for each user may be rewritten.

  Furthermore, the resetting of the display order described above not only changes the initial setting (at the time of shipment) but also at any time according to changes in the user's situation after resetting or when the user desires. , Can be done any number of times.

  A modification will be described below. In the above description, one of the plurality of pieces of biological information is set as the first display order, and the other biological information is automatically lowered according to the order of the initial state. Instead of this, the display order of all the biological information may be specified. Hereinafter, with reference to FIG. 5, the resetting of the display order in this modification will be described. Here, FIG. 5 is a flowchart showing a flow of resetting the display order of the biological information in the modification.

  First, the control unit 40 inputs 1 as the value of N, and stores the value of N in the storage unit 41 (step S11). Subsequently, the control unit 40 refers to the display order table, and displays the biological information with the first display order in the initial state on the display unit 21 (step S12).

  The user operates the operation unit 22 to input the display order (display order information) of the biological information displayed on the display unit 21 (step S13). The control unit 40 stores the input display order in association with the biological information in a storage area different from the display order table (step S14).

  Next, after confirming that N is not K (NO in step S15), the control unit 40 gives an instruction to rewrite N stored in the storage unit 41 to a new incremented N (step S17). ).

  Subsequently, the control unit 40 refers to the display order table and displays the biological information having the display order in the initial state corresponding to the new N on the display unit 21 (step S12). In response to this, the user operates the operation unit 22 to input the display order of the biological information displayed on the display unit 21 (step S13). The control unit 40 stores the input display order in association with the biological information in a storage area different from the display order table (step S14). The control unit 40 repeats the above process until N becomes K, and when N reaches K and the display order is reset for all biological information (YES in step S15), the new information stored in the storage unit 41 is stored. The new display order is overwritten on the display order table, a new display order is set (step S16), and the process is terminated (step S18).

  As described above, if the display order of all the biological information can be reset, it is possible to provide information more in line with the user's wishes. In addition, since an effect | action and effect other than this are the same as that of the above-mentioned embodiment, detailed description is abbreviate | omitted.

It may be configured as a body composition meter provided with a meter, and the height of the user may be obtained by measurement instead of input.

  Moreover, in the biometric apparatus 10 according to the above-described embodiment, the biometric information displayed on the display unit 21 has been described as being sequentially displayed one by one. However, the present invention is not limited to this, and any plural types of biometric information can be displayed. You may comprise so that the setting which displays biometric information at once can be performed. In this case, the display order information may include information for specifying the biological information to be displayed at the same time. For example, among the biological information, the setting of displaying “weight” and “fat percentage” first, By configuring the setting to display the "fat percentage", "lean mass", and "visceral fat area" first, even when there are multiple pieces of biological information (biological information displayed first) that the user wants to know Since it can respond, it is suitable. In addition, the biological information to be displayed first is a plurality of types and the biological information scrolled thereafter is one type at a time, or conversely, the biological information to be displayed first is one type and the biological information scrolled thereafter. A plurality of types of information may be configured and can be changed as appropriate.

  Although the present invention has been described with reference to the above embodiment, the present invention is not limited to the above embodiment, and can be improved or changed within the scope of the purpose of the improvement or the idea of the present invention.
