For example, the sensing unit 590 may be disposed in various areas, such as an upper surface area of the inner wall different from areas A and B, among the entire inner wall areas of the arm massage unit frames 511 and 531 .

Referring to FIG. 29B , the sensor 590 includes a first sensor 591 included in the first arm massage unit 510 and a second sensor 593 included in the second arm massage unit 530. can include

30 is a diagram for explaining a state of an arm air cell according to an embodiment of the present disclosure. Specifically, FIG. 30A is a diagram for explaining a contracted state of an arm air cell according to an embodiment of the present disclosure, and FIG. 30B is a diagram for explaining an expanded state of an arm air cell according to an embodiment of the present disclosure.

Referring to FIGS. 30A and 30B , the arm massage unit 500 may massage the user's arm by contracting and expanding the arm air cell 570 as shown in FIGS. 30A and 30B . In this case, contraction and expansion of the arm air cell 570 may be repeatedly performed.

When the arm air cell 570 is contracted as shown in FIG. 30A , the user's arm may freely move to at least one of the inside and outside of the arm massage unit 500 . However, when the arm massage unit 500 operates while the user's arm is moved to the outside of the arm massage unit 500, the operation for massaging the user's arm is performed even though the user's arm cannot be massaged. , Power of the arm massage unit 500 may be wasted.

Also, when the arm air cell 570 is inflated as shown in FIG. 30B , the user's arm cannot freely move from the inside to the outside or from the outside to the inside of the arm massage unit 500 . However, when the user moves the arm to the inside or outside of the arm massage unit 500 while the arm air cell 570 is inflated, the user's arm movement is hindered by the inflated arm air cell 570, allowing the user to A problem of not being able to freely use the arms may occur, resulting in a decrease in user satisfaction with the massage device 100 .

In other words, when the user's arm is not located inside the arm massage unit 500 in a state in which the arm massage unit 500 is driven, the arm massage unit 500 generates power according to an operation for massaging the user's arm. A problem of waste may occur and a user's satisfaction with the massage device 100 may decrease due to a problem of preventing the user from freely using the user's arm while the arm air cell 570 is inflated.

31 illustrates an example for explaining an operation of controlling an arm massage unit by a controller according to an embodiment of the present disclosure.

According to an embodiment of the present disclosure, the controller 300 may control the operation of the sensing unit 590 in the detection period and the operation of the arm massage unit 500 in the operation period. Through this, the controller 300 starts an arm massage by driving the arm massage unit 500 or stops the arm massage unit 500 to perform an arm massage according to whether or not the user's arm is sensed through the sensor 590. may suspend and/or terminate the department.

First, the control unit 300 may control the operation of the sensing unit 590 in the sensing period (S3110). For example, the control unit 300 may activate the sensing unit 590 by driving the sensing unit 590 in the sensing period. The activated sensing unit 590 may detect the user's arm and transmit a sensing signal to the first business 300 . In this case, the sensing period may be a period in which the user's arm is sensed. As described above, the sensing unit 590 may be various devices that sense the arm. The control unit 300 may repeatedly drive and stop the sensing unit 590 based on a preset time period.

The operating state of the arm massager 500 in the sensing period may be at least one of a driving state and a stationary state. The driving state may be a state in which the arm massage unit 500 operates (or is driven). The stop state may be a state in which the arm massage unit 500 is stopped (or does not operate).

Thereafter, the controller 300 may control the operation of the arm massage unit 500 in the operation section based on the detection signal of the sensor 590 (S3120). For example, the controller 300 may maintain or change the operation of the arm massage unit 500 based on the detection signal. At this time, the operation section may be a section for controlling the operation of the arm massage unit 500 . In the operating section, the sensing unit 500 is in an activated state, but is not limited thereto. For example, the sensing unit 500 may be inactivated in an operating period.

Finally, the controller 300 may control the operation of the arm massage unit 500 again based on the air pressure of the air cell 570 (S3130).

Hereinafter, steps S3120 and S3130 will be described in detail.

32 shows an example for explaining the operation of controlling the arm massage unit shown in FIG. 31 .

According to an embodiment of the present disclosure, the controller 300 may control the operation of the arm massage unit 500 based on the detection signal of the sensor 590 and the operating state of the arm massage unit 500 (S3120). ).

For example, the controller 300 determines whether or not the detection signal transmitted from the detector 590 is received, and controls the operation of the arm massage unit 500 based on the determination result and the operating state of the arm massage unit 500. It can be controlled (S3121).

For example, the controller 300 may perform a first determination of whether a detection signal is received (S3121a). When the sensing unit 590 detects the user's arm, the sensing unit 590 transmits a sensing signal to the control unit 300, and the control unit 300 may receive the sensing signal.

When the detection signal is received, the controller 300 may determine that the user's arm is accommodated in the accommodation space (S). When the detection signal is not received, the controller 300 may determine that the user's arm is not accommodated in the accommodation space (S).

The controller 300 may perform a second determination for determining whether the operating state of the arm massage unit 500 is a driving state (S3121b). Various information about the arm massage unit 500, such as air supply and air supply of the arm air cell 570, may be obtained. The control unit 300 may determine whether the operation state of the arm massage unit 500 is a driving state based on the acquired information.

The control unit 300 may control the operation of the arm massage unit 500 based on the first and second determination results (S3121c).

In case of at least one of a case where a detection signal is not received and the operating state is a stop state, and a case where a detection signal is received and the operating state is a driving state, the controller 300 controls the operation of the arm massage unit 500 in the operating section. can be maintained For example, the controller 300 maintains the arm massage unit 500 in a driven state when the operating state is in a driving state, and maintains the arm massage unit 500 in a stopped state when the operating state is in a stopped state. can be maintained

When the detection signal is not received and the operating state is a driving state, the control unit 300 may change the operation of the arm massaging unit 500 by stopping the arm massaging unit 300 .

When the detection signal is received and the operation state is in a stop state, the controller 500 may change the operation of the arm massage unit 500 by driving the arm massage unit 500 .

As described above, the control unit 300 may control the operation of the arm massage unit 500 by determining whether the user's arm is accommodated in the accommodating space S through the detection signal.

As another example, the controller 300 may control the operation of the arm massager 500 based on the detection signal, the operating state of the arm massager 500, and the reception time for the detection signal (S3122). In this case, the reception time may be an elapsed time from a time when the control unit 300 receives the detection signal transmitted from the sensing unit 590 to a time when the detection signal is not received. The receiving time may be determined based on the sensing time when the sensing unit 590 senses the user's arm. For example, the reception time may be longer when the detection time is longer than when the detection time is short. In other words, the reception time may increase as the sensor 590 detects the user's arm for a long time.

For example, the controller 300 may perform a first determination (S3122a) and a second determination (S3122b). Since S3122a is the same as the above-described S3121a and S3122b is the same as the above-described S3121b, a detailed description thereof will be omitted.

When the detection signal is received, the controller 300 may perform a third determination to determine whether the reception time for the detection signal is greater than or equal to a predetermined threshold reception time (S3122c). The critical reception time is preset through various objects, such as at least one of a company related to the massage device 100, a manager managing the massage device 100, and a user using the massage device 100, and stored in the memory 330. There may be. A company associated with the massage device 100 may be at least one of manufacturing, production, distribution, and sales of the massage device 100. The threshold receiving time may be a criterion for determining whether the user's arm is accommodated in the accommodating space S for a sufficient period of time. When the user's arm is accommodated in the accommodating space S for a sufficient period of time, the reception time may be greater than or equal to the threshold reception time.

For example, the controller 300 may compare the reception time and the threshold reception time to determine whether the reception time is greater than or equal to the threshold reception time. The controller 300 may determine that the user's arm is accommodated in the accommodating space S for a sufficient period of time when the reception time is greater than or equal to the threshold reception time. When the reception time is less than the critical reception time, the controller 300 may determine that the user's arm is not accommodated in the accommodation space S for a sufficient time. The controller 300 determines based on the second and third determination results. The operation of the arm massage unit 500 may be controlled (3122d).

In at least one of cases where the operating state is a driving state and the reception time is greater than or equal to the threshold reception time, and the operation state is in a stop state and the reception time is less than the threshold reception time, the control unit 300 controls the operation of the arm massage unit 500. can be maintained

When the operation state is the driving state and the reception time is less than the threshold reception time, the controller 300 may stop the arm massage unit 500 to change the operation of the arm massage unit 500 .

When the operation state is the stop state and the reception time is greater than or equal to the threshold reception time, the controller 300 may change the operation of the arm massage unit 500 by driving the arm massage unit 500 .

As described above, the control unit 300 can control the operation of the arm massage unit 500 by determining whether the user's arm has been accommodated in the accommodation space S for a sufficient period of time through the reception time of the detection signal. .

In addition, when the operation state of the arm massage unit 500 is changed to the driving state as described above, the control unit 300 may control the operation of the arm massage unit 500 again (S3130). When the operating state of the arm massage unit 500 is changed to the driving state, the controller 300 may control the operation of the arm massage unit 500 based on the air pressure of the air cell 570 .

For example, the controller 300 may control the operation of the arm massage unit 500 based on whether the air pressure of the air cell 570 is equal to or greater than a predetermined critical air pressure (S3131). As described above, the critical air pressure may be preset through various objects and stored in the memory 330 . The critical air pressure may be a criterion for determining whether the user's arm is accurately accommodated in the accommodating space (S). When the user's arm is accurately accommodated in the accommodating space S, the air pressure of the inflated air cell 570 may be greater than or equal to the critical air pressure.

For example, the controller 300 may inflate the air cell 570 (S3131a). The controller 300 may inflate the air cell 570 by supplying air to the air cell 570 by driving the air supply unit.

The controller 300 may perform a fourth determination to determine whether the air pressure of the inflated air cell 570 is equal to or greater than a predetermined critical air pressure (S3131b).

For example, the controller 300 may compare the air pressure of the inflated air cell 570 with the critical air pressure to determine whether the air pressure of the inflated air cell 570 is greater than or equal to the critical air pressure.

The controller 300 may determine that the user's arm is accurately accommodated in the accommodation space S when the air pressure of the inflated air cell 570 is equal to or greater than the critical air pressure. The controller 300 may determine that the user's arm is not accurately accommodated in the accommodation space S when the air pressure of the inflated air cell 570 is less than the critical air pressure.

The controller 300 may control the operation of the arm massage unit 500 based on the fourth determination result (S3131c).

When the air pressure of the inflated air cell 570 is equal to or higher than the critical air pressure, the controller 300 may maintain the operation of the arm massage unit 500 . In other words, the control unit 300 may maintain the operating state of the arm massage unit 500 in a driving state.

When the air pressure of the inflated air cell 570 is less than the critical air pressure, the controller 300 may stop the arm massage unit 500 to change the operation of the arm massage unit. In other words, the controller 300 may change the operating state of the arm massager 500 from a driving state to a stopped state.

As described above, the controller 300 can control the operation of the arm massager 500 by determining whether the user's arm is accurately accommodated in the accommodating space S through the air pressure of the air cell.

As another example, the controller 300 may control the operation of the arm massage unit 500 based on the air pressure of the air cell 570 and the re-reception time for the detection signal (S3132).

For example, the controller 300 may inflate the air cell 570 (S3132a) and perform a fourth determination (S3132b). Since S3132a is the same as the above-described S3131a and S3132b is the same as the above-described S3131b, a detailed description thereof will be omitted.

When the air pressure of the inflated air cell 570 is equal to or higher than the critical air pressure, the controller 300 may perform a fifth determination to determine whether the re-reception time for the detection signal is equal to or greater than the predetermined critical re-reception time (S3132c). . In this case, the re-reception time may be a reception time for a detection signal received by the controller 300 after the air cell 570 is inflated. The re-receiving time may be determined based on the sensing time for the sensing unit 590 to sense the user's arm after the air cell 590 is inflated. For example, the re-reception time may be longer when the sensing time after the air cell 570 is inflated is longer than when the sensing time after the air cell 570 is inflated is short. In other words, the re-reception time may increase as the sensing unit 590 senses the user's arm for a long time after the air cell 570 is inflated.

As described above, the critical re-reception time may be preset through various objects and stored in the memory 330 . The critical re-reception time may be a criterion for determining whether the user's arm is accommodated in the accommodating space S for a sufficient period of time after the air cell 570 is inflated. If the user's arm is accommodated in the accommodating space S for a sufficient period of time after the air cell 570 is inflated, the re-reception time may be greater than or equal to the critical re-reception time.

The aforementioned threshold reception time and threshold re-reception time may be the same as or different from each other. Preferably, the threshold re-reception time may be shorter than the threshold reception time, but is not limited thereto. For example, the threshold re-reception time may be longer than the threshold reception time.

For example, the controller 300 may compare the re-reception time and the critical re-reception time to determine whether the re-reception time is greater than or equal to the critical re-reception time.

The controller 300 may determine that the user's arm is accurately accommodated in the accommodating space S for a sufficient time when the re-reception time is equal to or greater than the critical re-reception time. When the re-reception time is less than the critical re-reception time, the controller 300 may determine that the user's arm is not accurately accommodated in the accommodating space S for a sufficient period of time.

The controller 300 may control the operation of the arm massage unit 500 based on the fifth determination result (S3132d).

When the re-reception time is greater than or equal to the critical re-reception time, the controller 300 may maintain the operation of the arm massage unit 500 . In other words, the control unit 300 may maintain the operating state of the arm massage unit 500 in a driving state.

When the re-reception time is less than the critical re-reception time, the controller 300 may stop the arm massage unit 500 to change the operation of the arm massage unit 500 . In other words, the controller 300 may change the operating state of the arm massager 500 from a driving state to a stopped state.

As described above, the controller 300 determines whether the user's arm is accurately accommodated in the accommodation space (S) through the air pressure of the air cell 570 and the re-reception time, and determines whether the user's arm is in the accommodation space (S) after the air cell is inflated. It is possible to control the operation of the arm massage unit 500 by determining whether or not S) has been accommodated for a sufficient time.

33 illustrates another example for explaining an arm massage unit control operation of a controller according to an embodiment of the present disclosure.

According to one embodiment of the present disclosure, the arm massage unit 500 may include electrodes disposed in the accommodating space. For example, the sensing unit 590 may be implemented as any one of the first and third biosignal measuring units 550 and 3210 . Any one measuring unit may include any one of the first bio-signal measuring electrode 980 and the third bio-signal measuring electrode 3320 . In other words, the electrode disposed in the accommodating space may be any one of the first bio-signal measuring electrode 980 and the third bio-signal measuring electrode 3320 . Hereinafter, for convenience of explanation, it will be assumed that the sensor 590 is implemented as the first biosignal measurer 550 .

According to an embodiment of the present disclosure, the controller 300 controls the operation of the first bio-signal measurer 550 in the detection period, and based on the electrical value of the first bio-signal measuring electrode 980 in the operation period. It is possible to control the operation of the arm massage unit 500.

For example, the controller 300 may control the operation of the first bio-signal measurer 550 in the detection period (S3140). For example, the controller 300 may activate the first biosignal measurer 550 by driving the first biosignal measurer 550 in the detection period. The activated first biosignal measuring unit 550 may transmit information about the electrical value of the first biosignal measuring electrode 980 to the controller 300 . The electrical value of the first bio-signal measuring electrode 980 may be at least one of voltage, current, resistance, and impedance of the first bio-signal measuring electrode 980 . The controller 300 may repeatedly drive and stop the first physiological signal measurer 550 based on a preset time period.

As described above, the first biosignal measuring unit 550 transmits the electric value of the first biosignal measuring electrode 980 to the controller 300, but is not limited thereto. For example, the first biosignal measurer 550 and the controller 300 are electrically connected to each other, and the controller 300 can obtain an electrical value of the electrode 980 for measuring the first biosignal.

The controller 300 may control the operation of the arm massage unit 500 in the operation section based on the electrical value of the first bio-signal measuring electrode 980 (S3150).

The controller 300 may control the operation of the arm massage unit 500 again based on the air pressure of the air cell 570 (S3160).

Hereinafter, steps S3150 and S3160 will be described in detail.

FIG. 34 shows an example for explaining the operation of controlling the arm massager shown in FIG. 33 .

According to an embodiment of the present disclosure, the controller 300 controls the operation of the arm massage unit 500 based on the electrical value of the first bio-signal measuring electrode 980 and the operating state of the arm massage unit 500. It can be done (S3150).

For example, the control unit 300 determines whether the electric value of the electrode 980 for measuring the first biosignal is changed, and based on the determination result and the operating state of the arm massage unit 500, the arm massager 500 It is possible to control the operation of (S3151).

For example, the controller 300 may perform a first determination of whether the electric value of the electrode 980 for measuring the first bio-signal changes or not (S3151a). When the first bio-signal measuring electrode 980 is in contact with the user's arm, the electrical value of the first bio-signal measuring electrode 980 may change.

When the electric value of the first bio-signal measuring electrode 980 changes, the controller 300 determines that the first bio-signal measuring electrode 980 is in contact with the user's arm, and the user's arm is placed in the receiving space (S). ) can be judged to have been accepted. When the electrical value of the first bio-signal measuring electrode 980 does not change, the controller 300 determines that the first bio-signal measuring electrode 980 is not in contact with the user's arm, so that the user's arm is in the receiving space. It may be determined that the operation state of the arm massage unit 500 is not accommodated in (S). The controller 300 may perform a second determination to determine whether the operating state of the arm massage unit 500 is a driving state (S3151b).

The controller 300 may control the operation of the arm massage unit 500 based on the first and second judgment results (S3151c).

A case where the electrical value of the first bio-signal measuring electrode 980 is not changed and the operating state is in a stopped state, or a case where the electrical value of the first bio-signal measuring electrode 980 is changed and the operating state is in a driving state In at least one case, the controller 300 may maintain the operation of the arm massage unit 500 .

When the electric value of the electrode 980 for measuring the first biosignal is not changed and the operating state is in the driving state, the controller 300 stops the arm massager 500 to change the operation of the arm massager 500. can

When the electrical value of the first bio-signal measuring electrode 980 is changed and the operation state is in a stop state, the controller 300 may change the operation of the arm massage unit 500 by driving the arm massage unit 500. As described above, the control unit 300 determines whether or not the user's arm is accommodated in the accommodation space S through the electrical value of the electrode 980 for measuring the first biosignal, thereby controlling the operation of the arm massage unit 500. can control.

As another example, the control unit 300 determines the electrical value of the first bio-signal measuring electrode 980, the operating state of the arm massage unit 500, and the amount of change and the amount of change in the electrical value of the first bio-signal measuring electrode 980. It is possible to control the operation of the arm massage unit 500 based on at least one of the change times for (S3152).

The amount of change may represent the degree to which the electrical value of the first bio-signal measuring electrode 980 changes. The amount of change may be determined based on at least one of a contact area between the user's arm and the first bio-signal measuring electrode 980 and the number of electrodes in contact with the user's arm. For example, the amount of change may be greater when the contact area is large than when the contact area is small. The amount of change may be greater when the number of electrodes in contact with the user's arm is greater than when the number of electrodes in contact with the user's arm is small. In other words, the amount of change may be turned on as the contact area increases or the number of electrodes in contact with the user's arm increases.

The change time may be an elapsed time from a point at which the electrical value of the first bio-signal measuring electrode 980 changes to a point at which the electrical value of the first bio-signal measuring electrode 980 does not change. The change time may be determined based on a contact time during which the arm of the user and the electrode 980 for measuring the first biosignal contact each other. For example, the change time may be longer when the contact time is longer than when the contact time is short. In other words, the change time may increase as the contact between the user's arm and the first bio-signal measuring electrode 980 is prolonged.

For example, the controller 300 may perform a first determination to determine whether the electric value changes (S3152a), and may perform a second determination to determine whether the operating state is a driving state (S3152b). Since S3152a is the same as the above-described S3151a and S3152b is the same as the above-described S3151b, a detailed description thereof will be omitted.

When the electrical value of the electrode 980 for measuring the first bio-signal changes, the controller 300 determines whether the amount of change in the electrical value of the electrode 980 for measuring the first bio-signal is greater than or equal to a preset threshold amount of change. At least one of determination and a fourth determination of determining whether the change time for the amount of change is greater than or equal to a predetermined threshold change time may be performed (S3152c). The threshold change amount and threshold change time may be previously set through the various objects described above and stored in the memory 330 . The threshold change amount and threshold change time may be criteria for determining whether the user's arm is accommodated in the accommodating space S for a sufficient period of time. When the user's arm is accommodated in the accommodating space S for a sufficient period of time, the amount of change in electrical value may be greater than or equal to the critical amount of change. When the user's arm is accommodated in the accommodating space S for a sufficient period of time, the change time for the change amount of the electrical value may be greater than or equal to the critical change time.

For example, the control unit 300 compares the amount of change in the electrical value and the critical amount of change to determine whether the amount of change in the electrical value is greater than or equal to the critical amount of change, and compares the change time for the amount of change with the critical change time so that the change time is the critical change. It can be judged whether it is over time.

The controller 300 may determine that the user's arm is accommodated in the accommodating space S for a sufficient period of time in at least one case of a change amount greater than or equal to a threshold change amount and a change time greater than or equal to a threshold change time. The control unit 300 may determine that the user's arm is not accommodated in the accommodating space S for a sufficient period of time in at least one of cases where the change amount is less than the threshold change amount and when the change time is less than the threshold change time.

The controller 300 may control the operation of the arm massage unit 500 based on the second determination result and at least one determination result among the third determination and the fourth determination (S3152d).

When at least one of the case where the change amount of the electric value is equal to or greater than the critical change amount and the change time for the change amount is equal to or greater than the critical change time, and the operating state is a driving state, the control unit 300 operates the arm massage unit 500. can keep

When at least one of the case where the change amount of the electric value is less than the critical change amount and the change time for the change amount is less than the critical change time, and the operation state is the stop state, the control unit 300 operates the arm massage unit 500 can keep

When at least one of the case where the change amount of the electric value is less than the critical change amount and the change time for the change amount is less than the critical change time, and the operating state is a driving state, the control unit 300 stops the arm massage unit 500 It is possible to change the operation of the arm massage unit 500.

When the amount of change in the electric value is at least one of the case where the change amount is greater than or equal to the critical change amount and the change time for the amount of change is greater than or equal to the critical change time, and the operation state is in a stop state, the controller 300 drives the arm massage unit 500. It is possible to change the operation of the arm massage unit 500.

In addition, when the operation state of the arm massage unit 500 is changed to the driving state as described above, the control unit 300 may control the operation of the arm massage unit 500 again (S3160). When the operating state of the arm massage unit 500 is changed to the driving state, the controller 300 may control the operation of the arm massage unit 500 based on the air pressure of the air cell 570 .

For example, the controller 300 may control the operation of the arm massage unit 500 based on whether the air pressure of the air cell 570 is equal to or higher than the critical air pressure (S3161).

For example, the controller 300 may inflate the air cell (S3161a). The controller 300 may perform a fifth determination of whether the air pressure of the inflated air cell is equal to or greater than the critical air pressure (S3161b). The controller 300 may control the operation of the arm massage unit 500 based on the fifth determination result (S3161c). S3161a is the same as the above-mentioned S3131a, S3161b is the same as the above-mentioned S3131b, and S3161c is the same as the above-mentioned S3131c, so a detailed description thereof will be omitted.

As another example, the controller 300 may control the operation of the arm massage unit 500 based on at least one of the air pressure of the air cell 570, the amount of re-change of electrical value, and the re-change time for the amount of re-change (S3162). ).

For example, the controller 300 may inflate the air cell 570 (S3162a) and perform a fifth determination (S3162b). Since S3162a is the same as the above-described S3161a and S3162b is the same as the above-described S3161b, a detailed description thereof will be omitted.

When the air pressure of the inflated air cell 570 is equal to or greater than the critical air pressure, the control unit 300 determines whether the amount of re-change of the electric value that changes after the air cell 570 is inflated is equal to or greater than the preset critical amount of re-change. At least one of , and a seventh judgment for determining whether the re-change time for the re-change amount is greater than or equal to a predetermined threshold re-change time may be performed (S3162c).

The re-change amount of the electrical value may represent the degree to which the electrical value of the first bio-signal measuring electrode 980 changes after the air cell 570 is inflated. The amount of re-change is at least among the contact area between the user's arm and the first bio-signal measuring electrode 980 after the air cell 570 is inflated and the number of electrodes in contact with the user's arm after the air cell 570 is inflated. can be determined based on one For example, the amount of re-change may be greater when the contact area after the air cell 570 is expanded is larger than when the contact area after the air cell 570 is expanded is small. The amount of change may be greater when the number of electrodes in contact with the user's arm is greater after the air cell 570 is inflated than when the number of electrodes in contact with the user's arm is small after the air cell 570 is inflated. In other words, the amount of re-change can be turned on as the contact area after the air cell 570 is inflated or the number of electrodes contacting the user's arm after the air cell 570 is inflated increases.

The re-change time for the re-change amount is the change in electrical value of the first bio-signal measuring electrode 980 from the point at which the electrical value of the first bio-signal measuring electrode 980 changes after the air cell 570 is inflated. It may be the elapsed time until the point of not doing it. The re-change time may be determined based on a contact time during which the user's arm and the first bio-signal measuring electrode 980 contact each other after the air cell 570 is inflated. For example, the change time may be longer when the contact time after the air cell 570 is inflated is longer than when the contact time after the air cell 570 is inflated is short. In other words, the re-change time may increase as the contact between the user's arm and the electrode 980 for measuring the first biosignal continues after the air cell 570 is inflated.

The threshold reset-change amount and the threshold reset-change time may be previously set through the above-described various objects and stored in the memory 330 . The critical reactivation amount and the critical reactivation time may be criteria for determining whether the user's arm is accommodated in the accommodating space S for a sufficient period of time. When the user's arm is accommodated in the accommodating space S for a sufficient period of time, the amount of re-change of the electric value may be greater than or equal to the critical amount of re-change. When the user's arm is accommodated in the accommodating space S for a sufficient period of time, the re-change time for the re-change amount of the electric value may be greater than or equal to the critical re-change time.

The above-described critical change amount and critical re-change amount may be the same as or different from each other, and the critical change time and critical re-change time may be the same as or different from each other. Preferably, the threshold change amount may be greater than the threshold change amount, but is not limited thereto. For example, the dark-field re-change amount may be smaller than the critical change amount. The threshold re-change time may be shorter than the threshold change time, but is not limited thereto. For example, the threshold re-change time may be longer than the threshold change time.

For example, the control unit 300 may compare the amount of re-change of electric value and the amount of critical re-change to determine whether the amount of re-change is greater than or equal to the critical amount of re-change. The product 300 may compare the re-change time for the amount of re-change and the critical re-change time to determine whether the re-change time is greater than or equal to the critical re-change time.

The controller 300 may determine that the user's arm has been accurately accommodated in the accommodating space S for a sufficient period of time in at least one of cases where the re-change amount is equal to or greater than the critical change amount and when the re-change time is equal to or greater than the critical re-change time. The control unit 300 may determine that the user's arm is not accurately accommodated in the accommodating space S for a sufficient period of time in at least one of cases where the re-change amount is less than the critical change amount and when the re-change time is less than the critical re-change time. .

The control unit 300 may control the operation of the arm massage unit 500 based on a result of at least one of the sixth and seventh judgments (S3162d). If the amount of re-change of the electrical value is greater than or equal to the critical amount of re-change and In at least one case among cases where the re-change time for the amount of re-change is greater than or equal to the critical re-change time, the controller 300 may maintain the operation of the arm massage unit 500 .

In case of at least one of the case where the amount of re-change of the electrical value is less than the critical amount of re-change and the case where the amount of re-change of the amount of re-change is less than the critical re-change time, the control unit 300 stops the arm massage unit 500 so that the arm massage unit The operation of 500 can be changed.

35 illustrates another example for explaining an arm massage unit control operation of a controller according to an embodiment of the present disclosure.

As described with reference to FIGS. 33 and 34 , the controller 300 controls the operation of the first bio-signal measurer 550 in the detection period and determines the electric value of the first bio-signal measuring electrode 980 in the operation period. Based on this, it is possible to control the operation of the arm massage unit 500, but is not limited thereto.

For example, the controller 300 may control the operation of the air cell 570 in the sensing period (S3170), and may control the operation of the arm massage unit 500 based on the air pressure of the air cell 570 (S3180). .

First, the controller 300 may inflate the air cell 570 in the detection period (S3170). Since S3170 is the same as S3131a, a detailed description thereof will be omitted.

Thereafter, the controller 300 may control the operation of the arm massager 500 in the operating section based on the air pressure of the inflated air cell 570 (S3180).

Hereinafter, step S3180 will be described in detail.

When the air pressure of the inflated air cell 570 is equal to or higher than the critical air pressure and the operation state is in a stop state, the controller 300 may change the operation of the arm massage unit 500 by driving the arm massage unit 500 .

Since S3182c is the same as the above-described S3151a, a detailed description thereof will be omitted.

The controller 300 may control the operation of the arm massage unit 500 based on the results of the second and third determinations (S3182d).

It is possible to change the operation of the arm massage unit 500 based on (S3183).

For example, the controller 300 performs a first determination to determine whether the air pressure of the inflated air cell 570 is equal to or greater than a critical air pressure (S3183a), and performs a second determination to determine whether the operating state is a driving state. It is performed (S3183b), and a third determination for determining whether or not the electric value is changed may be performed (S3183c). Since S3183a is the same as S3182a, S3183b is the same as S3182b, and S3183c is the same as S3182c, detailed descriptions will be omitted.

When the electric value is changed, the control unit 300 performs at least one of a fourth determination for determining whether the change amount of the electric value is greater than or equal to a threshold change amount and a fifth determination for determining whether a change time for the change amount is greater than or equal to a threshold change time. The determination of can be performed (S3183d). Since S3183d is identical to the above-described S3152c, a detailed description thereof will be omitted.
