Description

[Technical Field]

[0001] The present invention relates to a measuring device that measures the magnitude of rotational force when a user grips the main body of the measuring device with one hand and rotates a rotating body provided on the measuring device with the other hand. [Background Art]

[0002] In recent years, a decline in physical fitness accompanying aging, such as decreased muscle strength and decreased walking speed, called "frailty", has become a social problem. However, since frailty progresses gradually, it is difficult for a person to become aware of the decline in their physical fitness in daily life, and when they do become aware of the decline, their physical fitness has often decreased significantly, and considerable time and effort are required to recover physical fitness through rehabilitation.

[0003] Therefore, various methods have been proposed to visualize the decline in physical fitness by quantifying physical fitness in daily life. One of these methods is measurement of the force for opening the cap of a plastic bottle (hereinafter referred to as "cap opening force"). [Prior Art Documents] [Patent Documents]

[0004] [Patent Document 1] Japanese Patent No. 7162230 [Summary of the Invention] [Problem to be Solved by the Invention]

[0005] The upper limb function measuring device of Patent Document 1 evaluates changes in upper limb function by measuring the cap opening force for opening the cap of a plastic bottle.

[0006] This measuring device measures upper limb function by measuring torque using a torque sensor attached to a fixed shaft. The torque sensor, which measures torsional torque, is attached to the fixed shaft, which is a component of the measuring device. Unlike sensors that are fixed with screws, attaching such a torque sensor requires specific skills. Therefore, assembling the measuring device requires a person with specific skills.

[0035] According to the invention described in claim 10, since the pressing force is measured based on the rotational force from a state in which the first measuring unit is pressed, even minute changes in rotational force can be accurately captured.

[0036] According to the invention described in claim 11, the rotational force applied to the rotating body is directly transmitted to the pressure sensor of the first measuring unit, and since the rotational force can be measured with an easily installed pressure sensor, even a person without specific skills can easily assemble the measuring device.

[0045] Figure 1 shows the state of the measuring device in this embodiment during measurement. The measuring device 1 has a so-called PET bottle shape. The user holds the part at the top of the device corresponding to the PET bottle cap with one hand and the part at the bottom of the device corresponding to the PET bottle body with the other hand, and rotates the cap in the opening direction to measure the gripping force, which is the force used to grip the part corresponding to the PET bottle body, and the opening force, which is the force used to rotate the part corresponding to the PET bottle cap in the opening direction.

[0046] Figure 2 is a perspective view showing the inside of the part of the measuring device 1 that measures the opening force, and Figure 3 is a side view of Figure 2. Figure 4 is a cross-sectional view at position AA in Figure 3. At the top of the measuring device 1 is a cap 11, which is a rotating member corresponding to the cap of a PET bottle. Directly below the cap 11 is a rotating body 12 that rotates integrally with the cap 11, and below the rotating body 12 is a first pressure sensor 23. The first pressure sensor 23 constitutes the first measuring unit 22. The cap 11 is formed in a solid cylindrical shape, and multiple grooves for preventing slippage during rotation are formed on its circumferential surface parallel to the longitudinal direction of the main body 2 of the measuring device 1. The lower part of the cap 11 in Figures 2 and 3 is fixed to the upper part of the rotating body 12.

[0047] The rotating body 12 is integrally formed with a cylindrical portion 121 shown at the top and a semi-cylindrical portion 122 shown at the bottom in Figures 2 and 3. The cylindrical portion 121 is inserted through an opening 81 formed in the top lid 80 of the main body 2. The diameter of the cylindrical portion 121 is formed to be a predetermined amount smaller than the diameter of the opening 81, for example, 0.4 mm. As a result, a small space of about 0.2 mm is formed between the cylindrical portion 121 and the opening 81, so that even when the rotating body 12 rotates when the user rotates the cap 11, the rotating body 12 and the top lid 80 are less likely to come into contact, and the rotating body 12 rotates smoothly.

[0048] The semi-cylindrical portion 122 is the left half of a cylinder with the same diameter as the cylindrical portion 121, as shown in Figures 2-7, and is formed in a solid columnar shape. The flat portion 123 on the right side of the semi-cylindrical portion 122 extends downward from the lower surface of the cylindrical portion 121. The flat portion 123 faces the pressure-receiving portion 211 of the transmission portion 21 at a predetermined distance apart. The material of the rotating body 12 can be metal such as iron, steel, or aluminum, synthetic resins such as polypropylene or polyethylene, or wood.

[0049] Between the rotating body 12 and the first pressure sensor 23, there is a transmission unit 21 that transmits a force corresponding to the force received from the rotating body 12 to the first pressure sensor 23. The transmission unit 21 has a pressure receiving unit 211 that receives a first pressing force from the rotating body 12 and a pressing unit 212 that applies a second pressing force, which is a force corresponding to the first pressing force, to the first pressure sensor 23. Here, in the transmission unit 21, the part that is located near the rotating body 12 and comes into contact with the rotating body 12 is the pressure receiving unit 211. Furthermore, in the transmission unit 21, the part that is located near the first pressure sensor 23 and presses the first pressure sensor 23 with a second pressing force, which is a force corresponding to the first pressing force, when the pressure receiving unit 211 is pressed by the first pressing force from the rotating body 12 is the pressing unit 212.

[0050] The pressure-receiving portion 211 is formed in a thin plate shape and extends in the vertical direction as shown in Figures 2 and 3 before the rotating body 12 rotates. The lower end of the pressure-receiving portion 211 is connected to the inclined portion 26. The inclined portion 26 is installed at an inclination with respect to the longitudinal direction of the main body 2. The lower end of the inclined portion 26 is provided with a connecting portion 27, which is shown to extend in the vertical direction as shown in Figures 2 and 3. The connecting portion 27 connects the inclined portion 26 and the pressing portion 212. The pressing portion 212 comprises a horizontal portion 213 and a swinging portion 214. The horizontal portion 213 extends along the horizontal direction before the rotating body 12 shown in Figure 2 rotates. Below the horizontal portion 213 is the first pressure sensor 23, which constitutes the first measuring portion 22. Before the rotating body 12 rotates, the lower surface of the horizontal portion 213 is in contact with the first pressure sensor 23. The horizontal section 213 on which the rotating body 12 rotates presses against the first pressure sensor 23 by its own weight. The oscillating section 214 extends downward from both the left and right edges of the horizontal section 213. The rotating shaft 24 is connected to the left side of the oscillating section 214 in Figures 2 and 3. The lower end 2141 of the oscillating section is spaced a predetermined distance from the support plate 28 of the first pressure sensor 23 installed inside the main body 2.

[0051] Figure 8 is a perspective view showing the internal structure of the entire measuring device 1, and Figure 9 is a side view of Figure 8.

[0052] A cover 31 is positioned where the user grips the main body 2 of the measuring device 1 with their other hand, and a second pressure sensor 32 and a third pressure sensor 33 are positioned vertically to the right of the cover 31 in Figure 9. When the user grips the measuring device 1 so as to press the cover 31, as shown in Figure 1, the force pressing the cover 31 (i.e., the gripping force which is the force gripping the main body 2) is transmitted from the cover 31 to the second pressure sensor 32 and the third pressure sensor 33, and the gripping force is measured.

[0053] Figure 10 is a block diagram of the measuring device 1. The control unit 100 controls each part of the measuring device 1. The specific details of the control performed by the control unit 100 will be described later.

[0054] (First Embodiment) (Opening force measurement section) Figures 2 and 3 show the mechanism for measuring the opening force. Figure 4 is a cross-sectional view of the position AA in Figure 3. Figure 5 is a cross-sectional view of the position AA in Figure 3 when the rotating body 12 is rotated in the F1 direction. Figure 6 is a cross-sectional view of the position AA in Figure 3 when the rotating body 12 is rotated in the F2 direction. Figure 10 is a block diagram of the measuring device of this embodiment. When a user applies an opening force (i.e., rotational force) to the cap 11 fixed to the rotating body 12 with one hand, the rotating body 12 rotates together with the cap 11. The pressure-receiving portion 211 of the transmission unit 21 is located near the flat portion 123 of the semi-cylindrical portion 122 at the bottom of the rotating body (to the right of the flat portion 123 in Figures 2 and 3). As shown in Figure 5, when the rotating body 12 is rotated in the direction of F1, the rotating body 12 rotates, and the first end portion 1231 of the flat portion 123 of the semi-cylindrical portion 122 at the bottom of the rotating body presses against the pressure-receiving portion 211 of the transmission unit 21. The force pressing against the pressure-receiving portion 211 at this time is called the first pressing force. The first pressing force is, in other words, the opening force applied to the cap 11. As shown in Figure 7, the transmission unit 21, with its pressure-receiving portion 211 pressed by the first pressing force, rotates in the direction of B around the rotation axis 24, and the pressing portion 212 of the transmission unit 21 presses the first pressure sensor 23 in the direction of C with a second pressing force, which is a force corresponding to the first pressing force. Since the first pressing force can be calculated from the measurement result of the second pressing force based on the positional relationship between the rotating shaft 24, the pressure receiving part 211, and the pressing part 212, the opening force (i.e., rotational force) applied to the cap 11 can also be calculated based on the measurement result of the second pressing force. The opening force calculated based on this measurement result of the second pressing force is called the calculated opening force.

[0055] The control unit 100 controls the first pressure sensor 23 to measure the second pressing force applied by the pressing unit 212. The control unit 100 then causes the first output unit 25 to acquire a first output value based on the measurement result of the second pressing force by the first pressure sensor 23, and controls the first output unit 25 to output the acquired first output value. Here, a specific example of output is that the first output value acquired by the first output unit 25 may be transmitted wirelessly or via wire to a display unit (not shown) or storage unit (not shown) provided in the measuring device 1. Another example of output is that the value is transmitted to an external display device 60 of the measuring device 1 to display the first output value, or that it is transmitted to an external storage device 65 of the measuring device 1 to store the first output value. Furthermore, the measurement result may be transmitted to an external device of the measuring device 1, and the receiving device may emit a sound or light up a specific lamp according to the first output value.

[0056] The control unit 100 controls the first output unit 25 to acquire either the measurement result of the first pressure sensor or a calculated value calculated based on the measurement result of the first pressure sensor 23 as the first output value, and to output the acquired first output value. An example of a calculated value is the calculated opening force calculated based on the measured value of the second pressing force.

[0057] Furthermore, the rotating body 12 can also be rotated in the opposite direction to the F1 direction. As shown in Figure 6, when a user applies a rotational force in the F2 direction, opposite to the F1 direction, to the cap 11 fixed to the rotating body 12 with one hand, the rotating body 12 rotates in the F2 direction together with the cap 11. A pressure-receiving part 211 of the transmission unit 21 is located near the flat part 123 of the semi-cylindrical part 122 at the bottom of the rotating body (to the right of the flat part 123 in Figures 2 and 3). When the rotating body 12 is rotated in the F2 direction, the rotating body 12 rotates, and the second end 1232 of the flat part 123 of the semi-cylindrical part 122 at the bottom of the rotating body presses against the pressure-receiving part 211 of the transmission unit 21. The transmission of force after the pressure-receiving part 211 is pressed is the same as when the rotating body 12 is rotated in the F1 direction as shown in Figure 7.

[0058] As described above, the user can rotate the cap 11 and the rotating body 12 in any direction in the F1 and F2 directions. Therefore, the second pressing force applied to the first pressure sensor can be appropriately measured regardless of the direction in which the user rotates the cap 11. Furthermore, since the rotational force can be measured with an easily installed pressure sensor, the configuration of this embodiment allows even a person without specific skills to easily assemble the measuring device.

[0059] Looking at Figures 3 and 4, we can see that there is a gap 13 between the pressure-receiving part 211 and the rotating body 12. This gap was intentionally created.

[0060] If there is no gap 13 between the pressure-receiving part 211 and the rotating body 12, even when the user is gripping the cap 11 but not applying any force to open it, the pressure-receiving part 211 and the flat part 123 of the semi-cylindrical part 122 at the bottom of the rotating body are in contact, so there is a possibility that force is being applied from the rotating body 12 to the pressure-receiving part 211. If force is being applied from the rotating body 12 to the pressure-receiving part 211, then force is being applied from the pressing part 212 to the first pressure sensor 23, and the first pressure sensor 23 will detect a second pressing force even though the user is not applying any force to open the cap 11. In this state where a second pressing force has been detected, the measurement result when the user applies force to open the cap 11 will not be an accurate measurement result.

[0061] Therefore, as shown in Figures 3 and 4, by providing a gap 13 between the pressure receiving part 211 and the rotating body 12, when the user is not applying an opening force to the cap 11, no pressure is applied from the rotating body 12 to the pressure receiving part 211, and the measurement result of the first pressure sensor 23 when the user is not applying an opening force to the cap 11 becomes 0 (zero). By measuring the opening force from the state where the measurement result of the first pressure sensor 23 is 0 (zero), an accurate measurement result can be obtained. An example of a specific gap 13 is 0.5 mm to 3.0 mm.

[0062] As shown in Figure 1, when the user applies opening force to the cap 11 of the measuring device 1 with one hand, they grip the cover 31 of the measuring device 1 with the other hand.

[0063] Figures 8 and 9 show the inside of the second measuring unit 30, which measures the gripping force (i.e., gripping force) applied to the measuring device 1. When a user grips the cap 11 with one hand to measure the opening force and grips the measuring device 1 with the other hand to prevent the main body 2 from rotating along with the cap 11, a gripping force is applied to the two pressure sensors (second pressure sensor 32 and third pressure sensor 33) located on the back of the cover 31. When a gripping force is applied to the second pressure sensor 32 and the third pressure sensor 33, the control unit 100 controls the second pressure sensor 32, the third pressure sensor 33 and the second output unit 35 so that the second output unit 35 acquires a second output value based on the measurement results of the second pressure sensor 32 and the third pressure sensor 33. Subsequently, the control unit 100 controls the second output unit 35 to output the second output value acquired by the second output unit 35. Here, output refers to transmitting the second output value acquired by the second output unit 35 to an external device wirelessly or via a wired connection. Specific examples of output include "sent to the display device 60 to display the second output value," or "sent to the storage device 65 to store the second output value." Furthermore, "the second output value may be transmitted to an external device of the measuring device 1, and the other device that receives the second output value may emit a sound or light up a specific lamp according to the second output value."

[0064] In this embodiment, two pressure sensors (second pressure sensor 32 and third pressure sensor 33) are used to measure the gripping force, but the number of sensors used to measure the gripping force can be one or three or more.

[0065] Furthermore, the measuring device 1 is equipped with a first timer 50, and the control unit 100 controls the first timer 50 to measure the time T1 (hereinafter referred to as "first time T1") from the point when the first output value exceeds the first threshold until the first maximum value, which is the maximum value of the first output value, is reached, when the user applies opening force to the cap 11 with one hand. Here, both the first maximum value and the first time T1 are values ​​that serve as indicators for determining the degree of the user's frailty.

[0066] Figure 11 shows an example of the first graph 761, which shows the first output value and the first time T1, where the calculated opening force calculated from the second pressing force is the first output value. The horizontal axis is the time axis, and the vertical axis shows the calculated opening force (labeled as "opening force" in Figure 11), which is the first output value. When the user applies opening force to the cap 11, the first output value begins to rise (at time t1), and after the first output value reaches its maximum (i.e., the first maximum value) (at time t3), the first output value begins to decrease when the user stops applying opening force, and eventually the first output value becomes 0 (zero) (at time t4). In this first graph 761, the first time T1 is the time from when the first output value exceeds the first threshold (at time t2) to when it reaches the first maximum value (at time t3) (the period labeled "T1" in Figure 11).

[0067] As a concrete example of numerical values, in Figure 11, with the origin t0 of the first graph 761 set to 0 (zero) seconds, the point at which the first output value exceeds the first threshold (time t1) is 4.2 seconds later, and the point at which the first output value reaches the first maximum value (time t3) is 6.8 seconds later. Therefore, the first time T1 is 2.6 seconds.

[0068] Furthermore, the measuring device 1 is equipped with a first timer output unit 55, and the control unit 100 controls the first timer 50 and the first timer output unit 55 so that the first timer output unit 55 acquires the first time T1 measured by the first timer 50. Subsequently, the control unit 100 controls the first timer output unit 55 to output the acquired first time T1. Here, output refers to the first time T1 acquired by the first timer output unit 55 being transmitted to an external device wirelessly or via wired connection. Specific examples of output include "transmitting to a display device 60 to display the first time T1," or "transmitting to a storage device 65 to store the first time T1." In addition, there are cases where only the measurement result is transmitted to another device.

[0069] Furthermore, the measuring device 1 is equipped with a second timer 51, and the control unit 100 controls the second timer 51 to measure the time T2 (hereinafter referred to as "second time T2") from the point when the second output value based on the measurement results of the second pressure sensor 32 and the third pressure sensor 33 exceeds the second threshold until the second maximum value, which is the maximum value of the second output value, is reached, when the user presses the cover 31 of the measuring device 1 with the other hand. Here, both the second maximum value and the second time T2 are values ​​that serve as indicators for determining the degree of the user's frailty.

[0070] Figure 11 shows an example of a second graph 762 that shows the second output value and the second time T2, where the measurement results of the second pressure sensor 32 and the third pressure sensor 33 are used as the second output value. The horizontal axis is the time axis, and the vertical axis is the second output value. When the user presses the cover 31 of the main body 2 and applies gripping force, the second output value begins to rise (at time t5), and after the second output value reaches its maximum (i.e., the second maximum value) (at time t7), the second output value begins to decrease when the user stops applying gripping force, and eventually the second output value becomes 0 (zero) (at time t8). In this second graph 762, the second time T2 is the time from when the user starts applying gripping force and the second output value exceeds the second threshold (at time t6) until it reaches the second maximum value (at time t7) (the period labeled "T2" in Figure 11).

[0071] As a concrete example of numerical values, in Figure 11, with the origin t0 of the second graph 762 set as 0 seconds, the point at which the second output value exceeds the second threshold (time t6) is 3.2 seconds later, and the point at which the second output value reaches the second maximum value (time t7) is 7.1 seconds later. Therefore, the second time T2 is 3.9 seconds.

[0072] Furthermore, the measuring device 1 is equipped with a second timer output unit 56, and the control unit 100 controls the second timer 51 and the second timer output unit 56 so that the second timer output unit 56 acquires the second time T2 measured by the second timer 51. Subsequently, the control unit 100 controls the second timer output unit 56 to output the acquired second time T2. Here, output refers to the transmission of the acquired second time T2 by the second timer output unit 56 to an external device wirelessly or via wired connection. Specific examples of output include "transmitting to a display device 60 to display the second time T2" ​​or "transmitting to a storage device 65 to store the second time T2". In addition, there are cases where only the measurement result is transmitted to another device.

[0073] Furthermore, the measuring device 1 is equipped with a third timer 52, and the control unit 100 controls the third timer 52 to measure the time T3 from the moment the user grasps the measuring device 1 with their other hand and the second output value exceeds the second threshold, until the moment the user applies opening force to the cap 11 of the measuring device 1 with one hand and the first output value exceeds the first threshold. Here, the first threshold and the second threshold are values ​​set in advance before measurement, and the time T3 is one of the values ​​that serve as a guideline for determining the degree of the user's frailty.

[0074] Figure 11 shows the third time period T3 in graph 75 (i.e., the first graph 761 and the second graph 762). The horizontal axis is the time axis, the vertical axis of the first graph 761 shows the first output value, and the vertical axis of the second graph 762 shows the second output value. Here, the time point t0 in the first graph 761 and the time point t0 in the second graph 762 represent the same time. In these two graphs, the third time period T3 is the time from the point in time when the second output value exceeds the second threshold (t6) to the point in time when the first output value exceeds the first threshold (t2).

[0075] As a concrete example of numerical values, in Figure 11, if the origin of the first graph 761 and the second graph 762 is set to 0 seconds, the time when the second output value exceeds the second threshold (time t6) is 3.2 seconds later, and the time when the first output value exceeds the first threshold (time t2) is 4.2 seconds later. Therefore, the third time T3 is 1.0 second.

[0076] Furthermore, the measuring device 1 is equipped with a third timer output unit 57, and the control unit 100 controls the third timer 52 and the third timer output unit 57 so that the third timer output unit 57 acquires the measured third time T3. Subsequently, the control unit 100 controls the third timer output unit 57 to output the acquired third time T3. Here, output refers to the transmission of the acquired third time T3 by the third timer output unit 57 to an external device wirelessly or via wired connection. Specific examples of output include "transmitting to a display device 60 to display the third time T3" or "transmitting to a storage device 65 to store the third time T3". In addition, there are cases where the measurement result is simply transmitted to another device.

[0077] Furthermore, the measuring device 1 is equipped with a first buffer 40 that holds a first maximum value, which is the maximum value of the first output value. The control unit 100 controls the first pressure sensor 23 and the first buffer 40 so that the first buffer 40 acquires the first maximum value when the user applies opening force to the cap 11 with one hand.

[0078] Furthermore, the measuring device 1 is equipped with a first maximum value output unit 41, and the control unit 100 controls the first buffer 40 and the first maximum value output unit 41 so that the first maximum value output unit 41 acquires the first maximum value acquired by the first buffer 40. Subsequently, the control unit 100 controls the first maximum value output unit 41 to output the acquired first maximum value. Here, output refers to transmitting the first maximum value acquired by the first maximum value output unit 41 to an external device wirelessly or via wired connection. Specific examples of output include "transmitting to a display device 60 to display the first maximum value" or "transmitting to a storage device 65 to store the first maximum value". In addition, there are cases where only the first maximum value is transmitted to another device.

[0079] Furthermore, the measuring device 1 is equipped with a second buffer 42 that holds a second maximum value, which is the maximum value of the second output value. The control unit 100 controls the second pressure sensor 32, the third pressure sensor 33, and the second buffer 42 so that the second buffer 42 acquires the second maximum value when the user grasps the main body 2 with the other hand.

[0080] Furthermore, the measuring device 1 is equipped with a second maximum value output unit 43, and the control unit 100 controls the second buffer 42 and the second maximum value output unit 43 so that the second maximum value acquired by the second buffer 42 is acquired by the second maximum value output unit 43. Subsequently, the control unit 100 controls the second maximum value output unit 43 to output the acquired second maximum value. Here, output refers to the transmission of the acquired second maximum value by the second maximum value output unit 43 to an external device wirelessly or via a wired connection. Specific examples of output include "transmitting to a display device 60 to display the second maximum value" or "transmitting to a storage device 65 to store the second maximum value". In addition, there are cases where only the second maximum value is transmitted to another device.

[0081] Figure 12 shows an example of the display screen 70 of the display device 60 in this embodiment. The display screen 70 is a touch panel and has both a display function and an operation reception function that accepts input from the user. Past measurement data 71 is displayed at the top left of the screen. A start button 72 for starting measurement is displayed at the bottom left of the screen, and when the user presses the start button 72, a new measurement is started. Furthermore, after the user has pressed the start button 72, the measurement is stopped when the user presses the start button 72 again. A first display unit 73 that displays the measurement results related to the first output value is located at the top right of the screen. In this embodiment, the calculated opening force calculated from the measurement result of the second pressing force is set as the first output value, and the first output value is displayed as the opening force at position 733 on the first display unit 73. Furthermore, the value calculated from the maximum value of the second pressing force is set as the first maximum value, and the first maximum value is displayed as the maximum opening force at position 731 on the first display unit 73. Furthermore, the first time T1 is displayed at position 732 on the first display unit 73. A second display unit 74 is located at the bottom right of the screen to display the measurement results related to the second output value. In this embodiment, the measurement result of the gripping force is set as the second output value, and this second output value is displayed as the gripping force at position 744 on the second display unit 74. Furthermore, the maximum value of the gripping force is set as the second maximum value, and this second maximum value is displayed as the maximum gripping force at position 741 on the second display unit 74. In addition, the second time T2 is displayed at position 742 on the second display unit 74, and the third time T3 is displayed at position 743 on the second display unit 74.

[0082] In this embodiment, the measurement is started and stopped with a single start button 72, but a separate button for stopping the measurement may be provided in addition to the start button 72. Also, in this embodiment, a display device 60 with an operation reception function is shown, but the operation reception function may be provided by a device other than the display device 60.

[0083] (Second embodiment) Figures 13 to 16 show a second embodiment. In this embodiment, unlike the configuration of the first embodiment, there is no transmission unit 21, and when the user applies rotational force to the rotating body 12, the rotating body 12 directly presses the fourth pressure sensor 310, which is the third measuring unit. Figure 13 is a perspective view of the part of the measuring device 1 of this embodiment that measures the opening force (i.e., rotational force). Figure 14 is a side view of the same part as in Figure 13. Figure 15 is a cross-sectional view of the position A5-A5 in Figure 14. Figure 16 is a view of the same part as in Figure 15 when an opening force is applied to the measuring device 1. Figure 19 shows a block diagram of the measuring device 1 shown in this embodiment.

[0084] When a user applies an opening force (i.e., rotational force) to the cap 11 fixed to the rotating body 12 in the direction of F2 as shown in Figure 16, the rotating body 12 rotates in the direction of F2 together with the cap 11, and the second end 1232 of the semi-cylindrical portion 122 at the bottom of the rotating body presses the fourth pressure sensor 310 in the direction of C1. This allows the user's opening force to be measured. The configuration of this embodiment allows the rotational force to be measured with an easily attachable pressure sensor, so even people without specific skills can easily assemble the measuring device.

[0085] The third control unit 300 controls the fourth pressure sensor 310 to measure the pressing force applied by the second end 1232 of the semi-cylindrical portion 122 at the lower part of the rotating body. The third control unit 300 then causes the third output unit 305 to acquire a third output value based on the measurement result of the pressing force from the fourth pressure sensor 310, and controls the third output unit 305 to output the acquired third output value. Here, a specific example of output is that the third output value acquired by the third output unit 305 may be transmitted wirelessly or via wired to a display unit (not shown) or storage unit (not shown) provided in the measuring device 1. Another example of output is that the value is transmitted to an external display device 60 of the measuring device 1 to display the third output value, or that it is transmitted to an external storage device 65 of the measuring device 1 to store the third output value. Furthermore, "the measurement results are transmitted to an external device of the measuring device 1, and the other device that receives the measurement results emits a sound or lights up a specific lamp according to the third output value."

[0086] The third control unit 300 controls the third output unit 305 to acquire either the measurement result of the fourth pressure sensor 310 or a calculated value calculated based on the measurement result of the fourth pressure sensor 310 as the third output value, and to output the acquired third output value. An example of a calculated value is the calculated opening force calculated based on the measured pressing force value.

[0087] In this embodiment, the rotational force can only be measured when the rotating body is rotated in the F2 direction. However, when the user applies an opening force (i.e., rotational force) to the cap 11 in the opposite direction to F2, it is possible to measure the rotational force when the rotating body is rotated in the opposite direction to F2 by placing a pressure sensor at the position where the first end 1231 of the semi-cylindrical portion 122 at the bottom of the rotating body is pressed.

[0088] (Gripping force measurement part) As shown in Figure 1, when the user applies opening force to the cap 11 of the measuring device 1 with one hand, they grip the cover 31 of the measuring device 1 with the other hand.

[0089] The mechanism for measuring the gripping force (i.e., gripping force) of the measuring device 1 in this embodiment has a configuration in which the second pressure sensor 32 is replaced with a fifth pressure sensor 340 and the third pressure sensor 33 is replaced with a sixth pressure sensor 341, compared to the configuration of the first embodiment shown in Figures 8 and 9 (Figures 17 and 18). By adopting the configuration of this embodiment, it becomes possible to measure the gripping force.

[0090] When a user grips the cap 11 with one hand to measure the opening force and holds the measuring device 1 with the other hand to prevent the main body 2 from rotating together with the cap 11, gripping force is applied to the two pressure sensors (fifth pressure sensor 340 and sixth pressure sensor 341) located on the back of the cover 31. When gripping force is applied to the fifth pressure sensor 340 and the sixth pressure sensor 341, the third control unit 300 controls the fifth pressure sensor 340, the sixth pressure sensor 341 and the fourth output unit 306 so that the fourth output unit 306 acquires a fourth output value based on the measurement results of the fifth pressure sensor 340 and the sixth pressure sensor 341. Subsequently, the third control unit 300 controls the fourth output unit 306 to output the fourth output value acquired by the fourth output unit 306. Here, output refers to transmitting the fourth output value acquired by the fourth output unit 306 to an external device wirelessly or via a wired connection. Specific examples of output include "sent to the display device 60 to display the fourth output value," or "sent to the storage device 65 to store the fourth output value." Furthermore, "the fourth output value may be transmitted to an external device of the measuring device 1, and the other device that receives the fourth output value may emit a sound or light up a specific lamp according to the fourth output value."

[0091] In this embodiment, two pressure sensors (the fifth pressure sensor 340 and the sixth pressure sensor 341) are used to measure the gripping force, but the number of sensors used to measure the gripping force can be one or three or more.

[0092] Furthermore, the measuring device 1 is equipped with a fourth timer 320, and the third control unit 300 controls the fourth timer 320 to measure the time T4 (hereinafter referred to as "fourth time T4") from the point when the third output value exceeds the third threshold until the third maximum value, which is the maximum value of the third output value, when the user applies opening force to the cap 11 with one hand. Here, both the third maximum value and the fourth time T4 are values ​​that serve as indicators for determining the degree of the user's frailty.

[0093] Figure 20 shows an example of a third graph 763, which shows the third output value and the fourth time T4, with the calculated opening force being the third output value. The horizontal axis is the time axis, and the vertical axis shows the calculated opening force (labeled as "opening force" in Figure 20), which is the third output value. The third output value begins to rise when the user applies opening force to the cap 11 (at time t10), and after the third output value reaches its maximum (i.e., the third maximum value) (at time t12), the third output value begins to decrease when the user stops applying opening force, and eventually the third output value becomes 0 (zero) (at time t13). In this third graph 763, the fourth time T4 is the time from when the third output value exceeds the third threshold (at time t11) to when it reaches the third maximum value (at time t12) (the period labeled "T4" in Figure 20).

[0094] As a concrete example of numerical values, in Figure 20, with the origin t0 of the third graph 763 set as 0 (zero) seconds, the point at which the third output value exceeds the third threshold (time t11) is 4.2 seconds later, and the point at which the third output value reaches the third maximum value (time t12) is 6.8 seconds later. Therefore, the fourth time T4 is 2.6 seconds.

[0095] Furthermore, the measuring device 1 is equipped with a fourth timer output unit 321, and the third control unit 300 controls the fourth timer 320 and the fourth timer output unit 321 so that the fourth timer output unit 321 acquires the fourth time T4 measured by the fourth timer 320. Subsequently, the third control unit 300 controls the fourth timer output unit 321 to output the acquired fourth time T4. Here, output refers to the transmission of the acquired fourth time T4 by the fourth timer output unit 321 to an external device wirelessly or via wired connection. Specific examples of output include "transmitting to a display device 60 to display the fourth time T4" or "transmitting to a storage device 65 to store the fourth time T4". In addition, there are cases where only the measurement result is transmitted to another device.

[0096] Furthermore, the measuring device 1 is equipped with a fifth timer 350, and the third control unit 300 controls the fifth timer 350 to measure the time T5 (hereinafter referred to as "fifth time T5") from the point when the fourth output value based on the measurement results of the fifth pressure sensor 340 and the sixth pressure sensor 341 exceeds the fourth threshold until the fourth maximum value, which is the maximum value of the fourth output value, is reached, when the user presses the cover 31 of the measuring device 1 with the other hand. Here, both the fourth maximum value and the fifth time T5 are values ​​that serve as indicators for determining the degree of the user's frailty.

[0097] Figure 20 shows an example of a fourth graph 764, which shows the fourth output value and the fifth time T5, where the measurement results of the fifth pressure sensor 340 and the sixth pressure sensor 341 are used as the fourth output value. The horizontal axis is the time axis, and the vertical axis shows the fourth output value (in Figure 20, the fourth output value is labeled "gripping force"). When the user presses the cover 31 of the main body 2 and applies gripping force, the fourth output value begins to rise (at time t14), and after the fourth output value reaches its maximum (i.e., the fourth maximum value) (at time t16), when the user stops applying gripping force, the fourth output value begins to decrease and eventually becomes 0 (zero) (at time t17). In this fourth graph 764, the fifth time T5 refers to the time from when the user begins to apply gripping force and the fourth output value exceeds the fourth threshold (time t15) until it reaches the fourth maximum value (time t16) (the period labeled "T5" in Figure 20).

[0098] As a concrete example of numerical values, in Figure 20, with the origin t0 of the fourth graph 764 set as 0 seconds, the point at which the fourth output value exceeds the fourth threshold (time t15) is 3.2 seconds later, and the point at which the fourth output value reaches the fourth maximum value (time t16) is 7.1 seconds later. Therefore, the fifth time T5 is 3.9 seconds.

[0099] Furthermore, the measuring device 1 is equipped with a fifth timer output unit 351, and the third control unit 300 controls the fifth timer 350 and the fifth timer output unit 351 so that the fifth timer output unit 351 acquires the fifth time T5 measured by the fifth timer 350. Subsequently, the third control unit 300 controls the fifth timer output unit 351 to output the acquired fifth time T5. Here, output refers to transmitting the fifth time T5 acquired by the fifth timer output unit 351 to an external device wirelessly or via wired connection. Specific examples of output include "transmitting to a display device 60 to display the fifth time T5," or "transmitting to a storage device 65 to store the fifth time T5." In addition, there are cases where the measurement result is simply transmitted to another device.

[0100] Furthermore, the measuring device 1 is equipped with a sixth timer 370, and the third control unit 300 controls the sixth timer 370 to measure the time T6 from the moment the user grasps the measuring device 1 with their other hand and the fourth output value exceeds the fourth threshold, until the moment the user applies opening force to the cap 11 of the measuring device 1 with one hand and the third output value exceeds the third threshold. Here, the third and fourth thresholds are values ​​set in advance before measurement, and the time T6 is one of the values ​​that serve as a guideline for determining the degree of the user's frailty.

[0101] Figure 20 shows the sixth time step T6 in graph 76 (i.e., the third graph 763 and the fourth graph 764). The horizontal axis is the time axis, the vertical axis of the third graph 763 shows the third output value, and the vertical axis of the fourth graph 764 shows the fourth output value. Here, the time point t0 in the third graph 763 and the time point t0 in the fourth graph 764 represent the same time. In these two graphs, the sixth time step T6 is the time from the point when the fourth output value exceeds the fourth threshold (t15) to the point when the third output value exceeds the third threshold (t11).

[0102] As a concrete example of numerical values, in Figure 20, if the origin of the third graph 763 and the fourth graph 764 is set to 0 seconds, the point at which the fourth output value exceeds the fourth threshold (time t15) is 3.2 seconds later, and the point at which the third output value exceeds the third threshold (time t11) is 4.2 seconds later. Therefore, the sixth time T6 is 1.0 second.

[0103] Furthermore, the measuring device 1 is equipped with a sixth timer output unit 371, and the third control unit 300 controls the sixth timer 370 and the sixth timer output unit 371 so that the sixth timer output unit 371 acquires the measured sixth time T6. Subsequently, the third control unit 300 controls the sixth timer output unit 371 to output the acquired sixth time T6. Here, output refers to the transmission of the sixth time T6 acquired by the sixth timer output unit 371 to an external device wirelessly or via wired connection. Specific examples of output include "transmitting to a display device 60 to display the sixth time T6" or "transmitting to a storage device 65 to store the sixth time T6". In addition, there are cases where the measurement result is simply transmitted to another device.

[0104] Furthermore, the measuring device 1 is equipped with a third buffer 330 that holds the third maximum value, which is the maximum value of the third output value. The third control unit 300 controls the fourth pressure sensor 310 and the third buffer 330 so that the third buffer 330 acquires the third maximum value when the user applies opening force to the cap 11 with one hand.

[0105] Furthermore, the measuring device 1 is equipped with a third maximum value output unit 331, and the third control unit 300 controls the third buffer 330 and the third maximum value output unit 331 so that the third maximum value acquired by the third buffer 330 is acquired by the third maximum value output unit 331. Subsequently, the third control unit 300 controls the third maximum value output unit 331 to output the acquired third maximum value. Here, output refers to the transmission of the acquired third maximum value by the third maximum value output unit 331 to an external device wirelessly or via wired connection. Specific examples of output include "transmitting to a display device 60 to display the third maximum value" or "transmitting to a storage device 65 to store the third maximum value." In addition, there are cases where only the third maximum value is transmitted to another device.

[0106] Furthermore, the measuring device 1 is equipped with a fourth buffer 360 that holds the fourth maximum value, which is the maximum value of the fourth output value. The third control unit 300 controls the fifth pressure sensor 340, the sixth pressure sensor 341, and the fourth buffer 360 so that the fourth buffer 360 acquires the fourth maximum value when the user grasps the main body 2 with the other hand.

[0107] Furthermore, the measuring device 1 is equipped with a second maximum value output unit 43, and the control unit 100 controls the fourth buffer 360 and the fourth maximum value output unit 361 so that the fourth maximum value acquired by the fourth buffer 360 is acquired by the fourth maximum value output unit 361. Subsequently, the third control unit 300 controls the fourth maximum value output unit 361 to output the acquired fourth maximum value. Here, output refers to the transmission of the fourth maximum value acquired by the fourth maximum value output unit 361 to an external device wirelessly or via wired connection. Specific examples of output include "transmitting to a display device 60 to display the fourth maximum value" or "transmitting to a storage device 65 to store the fourth maximum value". In addition, there are cases where only the fourth maximum value is transmitted to another device.

[0108] Figure 21 shows an example of the display screen 90 of the display device 60 in this embodiment. The display screen 90 is a touch panel and has both a display function and an operation reception function that accepts input from the user. Past measurement data 91 is displayed at the top left of the screen. A start button 72 for starting measurement is displayed at the bottom left of the screen, and when the user presses the start button 72, a new measurement is started. Furthermore, after the user has pressed the start button 72, the measurement is stopped when the user presses the start button 72 again.

In this embodiment, the calculated opening force calculated from the measurement result of the pressing force is set as the third output value, and the third output value is displayed as the opening force at position 803 on the third display unit 93. Furthermore, the value calculated from the maximum value of the pressing force is set as the third maximum value, and the third maximum value is displayed as the maximum opening force at position 731 on the third display unit 93.

[0109] In this embodiment, the measurement is started and stopped with a single start button 72, but a separate button for stopping the measurement may be provided in addition to the start button 72.

[0110] (Third embodiment) Figures 22 to 26 show a third embodiment, which differs from the first embodiment in the shape of the transmission section and the position of the pressure sensor constituting the first measuring section. Figure 22 is a perspective view of the part of the measuring device 1 in this embodiment that measures the opening force (i.e., rotational force). Figure 23 is a side view of the same part as in Figure 22. Figure 24 is a cross-sectional view of the position A2-A2 in Figure 23. Figure 25 is a view of the same part as in Figure 24 when an opening force is applied to the measuring device 1. Figure 26 is a side view when an opening force is applied to the measuring device 1.

[0111] In this embodiment, the seventh pressure sensor 1051, which is the first measuring unit 22, is located to the right of the transmission unit 1000 in Figure 23. Similar to the first embodiment, when the user applies an opening force (i.e., rotational force) to the cap 11 fixed to the rotating body 12, the rotating body 12 rotates together with the cap 11. The pressure receiving part 1001 of the transmission unit 1000 is located near the flat part 123 of the semi-cylindrical part 122 at the bottom of the rotating body (to the right of the flat part 123 in Figures 24 and 25). As shown in Figure 25, when the rotating body 12 is rotated in the direction of F2, the rotating body 12 rotates, and the second end 1232 of the flat part 123 of the semi-cylindrical part 122 at the bottom of the rotating body presses the pressure receiving part 1001 of the transmission unit 1000 in the direction of C2. The force pressing the pressure receiving part 1001 at this time is called the first pressing force. The first pressing force is, in other words, the opening force applied to the cap 11. The transmission unit 1000, whose pressure-receiving part 1001 is pressed by the first pressing force, rotates in the direction D about the rotation axis 1052 as shown in Figure 26, and the pressing part 1002 of the transmission unit 1000 presses the seventh pressure sensor 1051 in the direction E with a second pressing force, which is a force corresponding to the first pressing force. Since the first pressing force can be calculated from the measurement result of the second pressing force based on the positional relationship between the rotation axis 1052, the pressure-receiving part 1001, and the pressing part 1002, the opening force applied to the cap 11 (i.e., rotational force) can also be calculated based on the measurement result of the second pressing force. The opening force calculated based on this measurement result of the second pressing force is called the calculated opening force.

[0112] The control unit 100 controls the seventh pressure sensor 1051 to measure the second pressing force applied by the pressing unit 1002. The control unit 100 then causes the first output unit 25 to acquire a first output value based on the measurement result of the second pressing force applied by the seventh pressure sensor 1051, and controls the first output unit 25 to output the first output value acquired by the first output unit 25.

[0113] (Fourth embodiment) Figures 27 and 28 show a fourth embodiment. This embodiment differs from the first and second embodiments in the shape of the lower part of the rotating body 12, the shape of the transmission section 1110, and the position of the first measuring section 22. Figure 27 is a perspective view of the part of the measuring device 1 of this embodiment that measures the opening force (i.e., rotational force). Figure 28 is a side view of the same part as in Figure 27.

[0114] In this embodiment, the lower part of the rotating body 12 (i.e., the lower part of the rotating body) is provided with screw threads 1100 around the circumference of a cylinder. The transmission unit 1110 has a recess in the center, and the inner surface of the recess is provided with screw threads that are paired with the screw threads 1100 on the lower part of the rotating body, so that the rotating body 12 and the transmission unit 1110 are interlocked. In this embodiment, the screw threads on the inner surface of the recess of the transmission unit 1110 correspond to the pressure receiving part, and the contact point between the transmission unit 1110 and the eighth pressure sensor 1101 is the pressing part 1113.

[0115] The rotating body 12 rotates in response to the user's opening force, but the rotating body 12 does not move in the vertical direction in Figure 28. The transmission unit 1110, which is coupled with the rotating body 12, moves in the vertical direction in Figure 28 along the guides located at the four corners as the rotating body 12 rotates.

[0116] In this embodiment, the configuration between the rotating body 12 and the eighth pressure sensor 1101 consists of a mated transmission unit 1110 and the rotating body 12. When rotational force is applied to the rotating body 12, the screw threads of the rotating body 12 also rotate simultaneously, and this rotation is transmitted as an axial thrust to the screw threads of the transmission unit 1110 via the mated unit. As a result, the transmission unit 1110 moves axially (i.e., in the C3 direction in Figure 28), and the pressing portion 1113 of the transmission unit 1110 presses the eighth pressure sensor 1101, which is positioned below it, in the direction of E.

[0117] Furthermore, if the transmission unit 1110 is in contact with the eighth pressure sensor 1101 before the user applies an opening force to the cap 11, the eighth pressure sensor 1101 may be pressed even before the user applies an opening force to the cap 11. If the eighth pressure sensor 1101 is pressed before the user applies an opening force, it may not be possible to accurately measure the opening force applied by the user to the cap 11. Therefore, by creating a gap between the transmission unit 1110 and the eighth pressure sensor 1101 before the user applies an opening force to the cap 11, no pressure is applied to the eighth pressure sensor 1101 when no opening force is applied, allowing for accurate measurement of the opening force.

[0118] (Fifth embodiment) Figures 29 to 33 show the measuring device 1 according to the fifth embodiment. In this embodiment, compared to the configuration of the first embodiment, a spring 1254 is provided that biases the transmission unit 1250 in the direction in which the transmission unit 1250 presses the ninth pressure sensor 1256, and when rotational force is applied to the rotating body 12, the transmission unit 1250 is configured to move around the rotation axis 1253 in a direction in which the pressing unit 1252 moves away from the ninth pressure sensor 1256. Figure 29 is a perspective view of the part of the measuring device 1 of this embodiment that measures the opening force (i.e., rotational force). Figure 30 is a side view of the same part as in Figure 29. Figure 31 is a cross-sectional view of the position A4-A4 in Figure 30. Figure 32 is a view of the same part as in Figure 31 when an opening force is applied to the measuring device 1. Figure 33 is a side view when an opening force is applied to the measuring device 1.

[0119] In this embodiment, as shown in Figures 29 and 30, a spring 1254 is placed between the spring base 1255 attached to the main body 2 and the transmission unit 1250, so that the spring 1254 biases the transmission unit 1250 in the direction H1 shown in Figure 30. Due to the biasing force of this spring 1254, the pressing part 1252 of the transmission unit 1250 presses the ninth pressure sensor 1256 in the direction E'. At this time, no opening force (i.e., rotational force) is applied to the cap 11. Figure 31 is a cross-sectional view of the measuring device 1 at this point.

[0120] Then, when the user applies an opening force (i.e., rotational force) to the cap 11, the rotating body 12 rotates. Figure 32 shows a cross-sectional view of the measuring device 1 when the user applies rotational force in the F1 direction. When the user applies rotational force in the F1 direction, the first end 1231 of the planar portion 123 of the semi-cylindrical portion 122 at the bottom of the rotating body presses the pressure receiving portion 1251 of the transmission portion 1250 in the C4 direction. The transmission portion 1250, having received the pressure in the C4 direction, then experiences a force acting in the D' direction, which rotates around the rotation axis 1253. As a result, the force that was pressing the ninth pressure sensor 1256 in the E' direction due to the biasing force of the spring 1254 becomes a force that presses in the E direction. The pressing force in the E' direction and the pressing force in the E direction are in the same direction, but their magnitudes are different, with the pressing force in the E direction being smaller. Based on the difference between the measured pressing force in the E' direction and the measured pressing force in the E direction by the ninth pressure sensor 1256, the opening force applied by the user to the cap 11 can be calculated.

[0121] Generally, pressure sensors have a measurement range with high measurement accuracy, but may have low accuracy when measuring minute pressing forces. However, as in this embodiment, by measuring from a state where the pressure sensor is pressed in advance, even if the opening force applied by the user is minute, it is possible to measure within the measurement range with high measurement accuracy of the pressure sensor.

[0122] Furthermore, in this embodiment, the transmission unit 1250 is configured to rotate in a direction opposite to the biasing force by the spring when it receives a pressing force due to the opening force, but it may also be configured to rotate in the same direction as the biasing force. In this case, the opening force applied by the user to the cap 11 can be calculated from the measurement value of the ninth pressure sensor 1256 before the opening force is applied and the measurement value of the ninth pressure sensor 1256 after the opening force is applied.

[0123] (Sixth embodiment) Figures 34 to 38 show a sixth embodiment. In this embodiment, compared to the configuration of the second embodiment, a spring 1310 is arranged to bias the rotating body in the direction that presses the 10th pressure sensor 1300 (direction F2 in Figure 37). When the user applies an opening force (i.e., rotational force) in the direction F1, which is opposite to the direction F2, the rotational force acts in a direction that weakens the pressing force applied to the 10th pressure sensor 1300. Figure 34 is a perspective view of the part of the measuring device 1 in this embodiment that measures the opening force, as seen from the side with the pressure sensor. Figure 35 is a side view of the same part as in Figure 34. Figure 36 is a perspective view of the part of the measuring device 1 in this embodiment that measures the opening force (i.e., rotational force), as seen from the side with the spring. Figure 37 is a cross-sectional view of the position A6-A6 in Figure 35. Figure 38 is a view of the same part as in Figure 37 when an opening force is applied to the measuring device 1.

[0124] In this embodiment, the spring 1310 presses against and biases the vicinity of the first end 1231, which is one end of the flat portion 123 of the semi-cylindrical portion 122 at the bottom of the rotating body. As a result, the rotating body 12 is biased in the direction of F2 in Figure 37 around the rotation axis of the rotating body by the pressing force from the spring 1310, and the second end 1232, which is the other end of the semi-cylindrical portion 122 at the bottom of the rotating body, presses against the tenth pressure sensor 1300 in the direction of C5'.

[0125] In this state, when the user applies an opening force (i.e., rotational force) in the direction of F1 in Figure 38, the force applied to the 10th pressure sensor 1300 changes to a pressing force in the direction of C5, according to the opening force applied by the user. The pressing force in the direction of C5' and the pressing force in the direction of C5 are in the same direction, but their magnitudes are different, with the pressing force in the direction of C5 being smaller. The 10th pressure sensor 1300 can calculate the opening force applied to the cap 11 from the measured values ​​of the pressing force in the direction of C5' and the pressing force in the direction of C5.

[0126] Pressure sensors generally have low measurement accuracy when subjected to small forces. In contrast, as in this embodiment, by measuring from a state where the pressure sensor is pressed in advance, rotational force can be measured within the measurement range where the pressure sensor has high measurement accuracy.

[0127] Furthermore, although this embodiment shows the case where an opening force is applied in a direction opposite to the biasing force by the spring, the opening force may also be applied in the same direction as the biasing force (i.e., in the F2 direction). In this case, the opening force applied to the cap can be calculated from the measurement value of the 10th pressure sensor 1300 before the opening force is applied and the measurement value of the 10th pressure sensor 1300 after the opening force is applied.

[0128] As described above, by visualizing the first maximum value, second maximum value, third maximum value, fourth maximum value, first hour T1, second hour T2, third hour T3, fourth hour T4, fifth hour T5, and sixth hour T6—values ​​that serve as indicators for determining the degree of the user's frailty—in addition to the current opening and gripping force, the degree of the user's frailty can be accurately grasped.

[0129] In the above embodiment, the display device 60 and storage device 65 are shown as being located outside the measuring device 1, but the invention is not limited to this. The display device provided in the measuring device 1 may display at least one of the following: the first output value, the second output value, the first maximum value, the second maximum value, the third output value, the fourth output value, the third maximum value, the fourth maximum value, and the first time, the second time, the third time, the fourth time, the fifth time, and the sixth time. Furthermore, the storage device provided in the measuring device 1 may store at least one of the following: the first output value, the second output value, the first maximum value, the second maximum value, the third output value, the fourth output value, the third maximum value, the fourth maximum value, and the first time, the second time, the third time, the fourth time, the fifth time, and the sixth time.

[0130] In the above embodiment, the user grips the measuring device 1 by pressing the cover 31 with four fingers from the index finger to the little finger and pressing the side of the main body 2 opposite the cover 31 with the thumb. However, the device is not limited to this, and the gripping force measured by the second measuring unit 30 is not limited to the four fingers of the index, middle, ring, and little fingers. It may be measured using only the index finger, or the gripping force of only one finger, such as the middle finger or any other finger. It may also be measured using two or three fingers to grip the main body 2. Furthermore, instead of using four fingers, the force of the thumb applied when gripping the main body 2 may be measured. In addition, the measuring device 1 is shown in the form of a PET bottle, but is not limited to this, and may be a rod-shaped member with one end rotating relative to the other end, or a plate-shaped member.
