Description

Technical Field

[0001] The present invention relates to an indicator for a measuring device used in a skin condition measuring device for measuring human skin conditions, and more particularly to an indicator for a measuring device having two or more movable parts that can be separated and independently moved, which can display the positions of the movable parts in which they are located by a simple and highly reliable mechanism. Background Art

[0002] As a device for measuring properties such as the water content and elasticity of human skin, a skin property measuring device is known. Among them, the water content of the skin is usually measured by pressing a pair of electrodes consisting of a positive electrode and a negative electrode against the skin to allow current to flow, and measuring the conductivity (electrical conductivity) of the skin between the electrodes. However, in the above-mentioned method for measuring the water content of the skin, the measurement sensitivity varies depending on the contact angle between the electrode and the skin and the pressing force, so there is a problem that it is difficult to reproducibly measure the accurate water content of the skin.

[0003] Therefore, in order to stabilize the pressing force between the electrode and the skin, as described in Japanese Patent Gazette No. 2003-169787 (Patent Document 1), the following skin moisture measuring device has been developed: a sensor having an electrode that is pressed against human skin is movably mounted on a housing via a spring, and the user is notified when a specified pressing force is applied to the sensor, thereby facilitating the measurement of the moisture content of the skin under a constant pressing force.

[0004] However, the skin moisture measuring device described in Patent Document 1 is not only unable to stabilize the contact angle between the sensor and the skin, but also the skin of the part pressed by the sensor is deformed, and the skin of the peripheral part is also deformed in a large range. Therefore, the elastic force of the skin of the measuring part is not only affected by the change of elastic force caused by the deformation of the skin pressed by the sensor, but also by the tensile stress generated by the deformation of the skin of the peripheral part, and there is a problem of becoming extremely unstable. That is, the skin moisture measuring device described in Patent Document 1 has the following problem: even if the pressing force generated by the sensor on the device side is constant and stabilized, if the elastic force of the skin required for measuring the water content on the human body side is not stabilized, it is impossible to reproduce the accurate water content of the skin.

[0005] On the other hand, in order to stabilize the contact angle and pressing force between the electrode and the skin, a skin property measuring probe has been developed, for example as described in Japanese Patent Gazette No. 2001-046344 (Patent Document 2): the electrode pressed against the human skin is arranged in a ring shape on a probe end face having a certain area, and the probe end face is pressed via a spring, thereby measuring the moisture content of the skin.

[0006] However, in the skin property measuring probe described in Patent Document 2, the probe end face on which the electrodes are arranged is formed by a plane having a relatively wide area. Therefore, for a part such as a human arm which has almost no flat part and most of which is formed by a curved surface, even if the probe end face is pressed against the skin, a pressure distribution will be generated in the probe end face and the electrode. As a result, the pressing force generated on the electrode becomes uneven and unstable, and there is a problem that the accurate measurement of the moisture content of the skin cannot be reproduced well.

[0007] Furthermore, in the skin moisture measurement device described in Patent Document 1, a display mechanism has been developed that displays the relative positions of a sensor including electrodes and a housing to inform the user of an appropriate pressing force on the sensor.

[0008] However, the display mechanism described in Patent Document 1 will display that an appropriate pressing pressure has been reached as long as the sensor is moved to a specified position relative to the housing, even though the pressing pressure is not actually appropriate when the sensor having an electrode is not pressed against the human skin at an appropriate pressing angle. Therefore, there is still a problem that poor measurement caused by poor pressing of the sensor part cannot be prevented.

[0013] Problems to be solved by the invention

[0014] Therefore, an object of the present invention is to provide an indicator for a measuring device such as a skin condition measuring device for measuring human skin conditions, which can display the degree of progress of at least two or more states such as the pressing angle of a sensor part, the pressing pressure of a sensor part, etc. by a simple mechanism.

[0015] The present inventors have repeatedly conducted in-depth studies on the structure of measuring devices such as skin condition measuring devices for measuring human skin conditions, and as a result, they have found that if there are parts that are movable according to their respective states when detecting the pressing angle of the sensor part, the pressing pressure of the sensor part, etc., then it is possible to solve the above-mentioned problems by providing display parts that are mechanically connected to the movable parts respectively, and arranging and displaying them neatly in one window, thereby completing the present invention.

[0016] That is, according to the present invention, there is provided an indicator for a measuring device, which is arranged in the measuring device, and the measuring device comprises: a frame; a measurement auxiliary unit, which is slidably supported on the frame; and a sensor part, which is slidably supported on the measurement auxiliary unit, and is characterized in that the indicator for the measuring device comprises: a window part, which is formed on a side surface of the frame; a first display part, which is slidably supported inside the window part and connected to the measurement auxiliary unit; and a second display part, which is slidably supported inside the window part and connected to the sensor part, and is configured so that the sliding direction and sliding amount of the first display part are consistent with the sliding direction and sliding amount of the measurement auxiliary unit, and the sliding direction and sliding amount of the second display part are consistent with the sliding direction and sliding amount of the sensor part.

[0017] The indicator for the measuring device of the present invention, for example, in the case where the indicator has two movable parts such as a sensor part for measuring the skin property of the measured person and a measurement auxiliary unit for guiding the sensor part, respectively and independently, as in the skin property measuring device, by providing an indicator having a first display part for displaying the operation of the measurement auxiliary unit and a second display part for displaying the operation of the sensor part, it is possible to easily grasp the positions of the measurement auxiliary unit and the sensor part in which states they are respectively located by visual observation, and it is possible to prevent human measurement errors caused by poor pressing of the cover part of the measurement auxiliary unit, for example, in the case where the measurement is not started due to insufficient pressing of the measurement auxiliary unit and the sensor part, the user can easily recognize the reason for the failure to start the measurement (insufficient pressing). In addition, since the first display part and the second display part are mechanically linked to the measurement auxiliary unit and the sensor part, it also has the advantages of simple structure, no need for power supply, and extremely high reliability.

[0018] In the indicator for a measuring device of the present invention, it is preferred that the first display section and the second display section each have an area composed of at least two or more different display colors, patterns, or a combination thereof.

[0019] In addition, the indicator for the measuring device of the present invention is more preferably that the first display part has a first area and a second area, the first area is composed of a first display color, pattern or a combination thereof indicating that the cover part is in a first position relative to the frame, and the second area is composed of a second display color, pattern or a combination thereof indicating that the cover part is in a second position relative to the frame, and the second display part has a third area and a fourth area, the third area is composed of a third display color, pattern or a combination thereof indicating that the sensor part is in a third position relative to the frame, and the fourth area is composed of a fourth display color, pattern or a combination thereof indicating that the sensor part is in a fourth position relative to the frame.

[0020] In addition, the indicator for the measuring device of the present invention is preferably configured such that when the display in the window portion is a combination of the first area and the third area, it indicates that the sensor portion is in a standby state, when the display in the window portion is a combination of the second area and the third area, it indicates that the sensor portion is in a contact state, and when the display in the window portion is a combination of the second area and the fourth area, it indicates that the sensor portion is in a measurement start state. In addition, when the second display portion in the window portion simultaneously displays the third area and the fourth area (the boundary between the third area and the fourth area), it is possible to inform the user that the sensor portion is not fully pressed in to the correct position and the appropriate pressing force.

[0021] According to the present invention, since a first display portion directly connected to the measurement auxiliary unit and distinguished by at least two or more different colors, patterns or combinations thereof, and a second display portion directly connected to the sensor portion and distinguished by at least two or more different colors, patterns or combinations thereof are displayed in a window portion, multiple states of the skin condition measuring device can be easily identified by displays such as colors, patterns, and combinations thereof, and human measurement errors caused by poor insertion of the cover portion and the sensor portion of the measurement auxiliary unit can be more reliably prevented.

[0022] In particular, in the indicator for the measuring device of the present invention, when the sensor portion is pressed obliquely against the skin of the person being measured, the guide surface of the cover portion becomes an obstacle and the front end of the sensor portion cannot contact the skin of the person being measured, or at least cannot move to a state where the switch described later is turned on. Therefore, the display in the window portion does not advance to the combination of the second area and the fourth area, and the user can be accurately informed that the sensor portion is not properly pressed.

[0023] In the indicator of the present invention, the measuring device may be configured such that an electrode consisting of a pair of positive and negative electrodes for measuring the moisture content of the skin of the person to be measured is provided at the front end of the sensor part, the measuring auxiliary unit is configured such that the sliding part is supported on the frame in a slidable manner, the cover part has a guide surface for pressing against the skin of the person to be measured and an opening part arranged in the guide surface for the electrode of the front end of the sensor part to enter and exit, and the cover part is detachably connected to the sliding part, and the measuring device includes: a first force applying mechanism that applies force to the sensor part in such a manner that the electrode of the front end of the sensor part is separated from the sliding part; and a second force applying mechanism that applies force to the sliding part in such a manner that the guide surface is separated from the frame. In addition, if the measuring object is skin, even if it is the skin of an animal, the above-mentioned measuring device can measure its skin properties such as moisture content and elasticity.

[0024] In this case, it is preferable to arrange a plurality of electrodes at the tip of the sensor portion in order to improve the measurement accuracy of the moisture content of the skin of the measurement subject.

[0025] Furthermore, in the indicator of the present invention, preferably, the measuring device is configured such that as the guide surface is pressed by the skin of the person being measured, first only the guide surface moves toward the frame, and then the guide surface and the electrode at the front end of the sensor portion move toward the frame.

[0026] In the present invention, the measuring device has the above-mentioned structure, and as the guide surface of the cover of the measuring device is pressed by the skin of the person being measured, before the electrode at the front end of the sensor part contacts the skin of the person being measured, the guide surface having a contact area larger than the front end contacts the skin of the person being measured. Therefore, in the present invention, the cover is first guided in a manner that the pressing angle is right angles relative to the skin surface of the person being measured, and then when the electrode at the front end of the sensor part contacts the skin of the person being measured, the electrode at the front end of the sensor part is also guided by the cover in a manner that the pressing angle is right angles relative to the skin surface of the person being measured, so that the skin properties of the person being measured can be measured in an appropriate contact manner.

[0027] In the present invention, it is preferred that the structure is such that as the guide surface of the cover part of the measuring device is pressed by the skin of the person being measured, after the guide surface and the electrode at the front end of the sensor part move toward the frame, only the electrode at the front end of the sensor part moves further toward the frame.

[0028] In addition, in the indicator of the present invention, it is preferred that the measuring device is configured so that after the guide surface of the cover part is pressed by the skin of the person being measured and the guide surface and the electrode at the front end of the sensor part move toward the frame, the pressing pressure per unit area generated at the front end of the sensor part is the same as or greater than the pressing pressure per unit area generated on the guide surface.

[0029] According to the present invention, after the guide surface of the measuring device and the electrode at the front end of the sensor unit move toward the frame, the skin of the subject exposed in the opening of the guide surface is fixed by the edge of the opening, thereby maintaining a uniform and constant elastic force. Therefore, after the above-mentioned action, by configuring the pressure per unit area generated at the front end of the sensor unit to be the same as or greater than the pressure per unit area generated at the guide surface, the electrode at the front end of the sensor unit does not depend on the amount of pressure (pressing force) of the guide surface, and can preferably contact the skin of the subject maintained with a uniform and constant elastic force, and can measure the skin properties with high accuracy.

[0030] Furthermore, in the indicator of the present invention, preferably, the measuring device has a switch installed at the base of the frame, and is configured so that the rear end of the sensor portion turns on the switch by moving the electrode at the front end of the sensor portion toward the frame to a predetermined position.

[0031] According to the present invention, the electrode at the front end of the sensor part of the measuring device is guided in such a manner that the pressing angle is at right angles to the skin surface of the person being measured, and the switch is turned on while the skin of the person being measured is maintained with uniform and constant elasticity to start the measurement, thereby being able to accurately and stably measure skin properties such as moisture content and elasticity.

[0032] In the indicator of the present invention, it is preferred that the measuring device is configured so that the first and second force-applying mechanisms can be simply supported and compactly arranged, and a first cylindrical portion that is in sliding contact with the base is provided on the sensor portion, and a second cylindrical portion that is in sliding contact with the sensor portion is provided on the base, and the center axis of the first cylindrical portion and the center axis of the second cylindrical portion are arranged on the same axis.

[0033] Furthermore, more preferably, when the sliding portion of the measuring device has an opening portion that comes into sliding contact with the sensor portion, the central axis of the opening portion and the central axis of the first cylindrical portion of the sensor portion are arranged coaxially.

[0034] In the indicator of the present invention, as described above, it is preferred that, when the sensor portion of the measuring device has a first cylindrical portion and the base has a first cylindrical portion, in the measuring device, the first force applying mechanism uses a first coil spring, the second force applying mechanism uses a second coil spring, and the center axis of the first coil spring and the center axis of the second coil spring are arranged coaxially.

[0035] In the indicator of the present invention, preferably, the first coil spring of the measuring device is arranged between the base and the sensor portion, and the second coil spring is arranged between the base and the sliding portion.

[0036] In the indicator of the present invention, in order to minimize the occurrence of human errors as described above, it is preferred that the cover of the measurement auxiliary unit of the measuring device is transparent or translucent so that the sensor part in the cover and the contact state between the sensor part and the skin of the person being measured can be visually observed.

[0037] Effects of the Invention

[0038] According to the present invention, there is provided an indicator for a measuring device, which is arranged in the measuring device, and the measuring device comprises: a frame; a measurement auxiliary unit, which is slidably supported on the frame; and a sensor part, which is slidably supported on the measurement auxiliary unit, wherein the indicator comprises: a window part, which is formed on a side surface of the frame; a first display part, which is slidably supported inside the window part and connected to the measurement auxiliary unit; and a second display part, which is slidably supported inside the window part and connected to the sensor part, and is configured so that the sliding direction and sliding amount of the first display part are consistent with the sliding direction and sliding amount of the measurement auxiliary unit, and the sliding direction and sliding amount of the second display part are consistent with the sliding direction and sliding amount of the sensor part.

[0039] According to the present invention, by providing an indicator having a first display portion for displaying the movement of a measurement auxiliary unit (a cover portion and a sliding portion) and a second display portion for displaying the movement of a sensor portion, respectively, it is possible to easily grasp by visual inspection the positions of the measurement auxiliary unit and the sensor portion, respectively, and to prevent human measurement errors caused by poor pressing of the cover portion and the sensor portion of the measurement auxiliary unit, etc.

[0040] In addition, in the indicator of the present invention, it can also be constructed as follows: the measuring device is provided with an electrode consisting of a pair of positive and negative electrodes at the front end portion of the sensor part for measuring the moisture content of the skin of the person being measured, and the measurement auxiliary unit is composed of a sliding part and a cover part, the sliding part is supported on the frame in a slidable manner, the cover part has a guide surface for pressing on the skin of the person being measured and an opening portion arranged in the guide surface for allowing the electrode at the front end portion of the sensor part to enter and exit, and the cover part can be connected to the sliding part in a loadable and detachable manner, and the measuring device has: a first force applying mechanism, which applies force to the sensor part in a manner that moves the electrode at the front end portion of the sensor part away from the sliding part; and a second force applying mechanism, which applies force to the sliding part in a manner that moves the guide surface away from the frame.

[0041] In the indicator of the present invention, before the front end portion of the sensor part of the measuring device contacts the skin of the person being measured, the guide surface of the measurement auxiliary unit having a contact area larger than that of the front end portion contacts the skin of the person being measured. Therefore, first, the cover part of the measurement auxiliary unit is guided in such a manner that the pressing angle becomes right angles relative to the skin surface of the person being measured, and then the front end portion of the sensor part is also guided by the cover part in such a manner that the pressing angle becomes right angles relative to the skin surface of the person being measured. As a result, the skin properties of the person being measured can be measured in an appropriate contact manner.

[0042] In addition, in the indicator of the present invention, the skin of the subject exposed in the opening of the guide surface of the measurement auxiliary unit of the measuring device is fixed by the edge of the opening. Therefore, the front end of the sensor part does not depend on the amount of pressure (pressing force) of the guide surface, and can preferentially contact the skin of the subject maintained with uniform and constant elastic force, thereby improving the measurement accuracy of skin properties.

It should be noted that the present invention is not limited to the following embodiments, and various modifications can be made without departing from the technical concept of the present invention.

[0048] Example

[0049] <Skin property measurement device>

[0050] exist Figure 1 , a perspective view showing the entirety of a skin condition measuring device 1 to which an indicator 8 according to an embodiment of the present invention is applied is shown. Figure 2 , a cross-sectional view partially showing the interior of a skin condition measurement device 1 to which an indicator 8 according to an embodiment of the present invention is applied is shown.

The structure and operation of the skin condition measurement device 1 to which the indicator 8 according to one embodiment of the present invention is applied are described below. It should be noted that in this application specification, "upper" such as upper part or upper end refers to the upper part of the skin condition measurement device 1. Figure 2 The upper side, lower part, lower end, etc. of the drawings refer to the upper side of the skin condition measurement device 1. Figure 2 .

[0051] [Frame]

[0052] As reference Figure 1 , 2 As can be understood, the skin condition measurement device 1 of the present embodiment is a handheld measurement device of a size that can be operated by a user with one hand, and has a frame 2 with a runway-shaped cross section, one end of which is open and a silicone cover 21 with a power switch is installed at the other end. A base 20 is fixed inside the frame 2, and a control substrate 22 on which an IC chip or the like for controlling the measurement of the skin condition measurement device 1 is mounted, and a power source 23 such as a battery for driving the control substrate 22 are installed. The power source 23 such as a battery inside the frame 2 can be replaced by removing a part of the side of the frame 2. It should be noted that the shape of the cross section of the frame 2 does not necessarily have to be a runway shape, and can also be other common shapes such as a rectangle, a polygon, a circle, an ellipse, etc. as long as it can accommodate necessary equipment such as the control substrate 22 and the power source 23 and can be operated with one hand.

[0053] [Base]

[0054] The base 20 may be an independent component separated from the frame 2, or may be a component formed integrally with the frame 2. The base 20 has a first flange portion 200 and a second cylindrical portion 201 which is entirely or partially hollow or solid and extends downward from the first flange portion 200. The central axis b of the second cylindrical portion 201 is installed inside the frame 2 in a manner consistent with the central axis (not shown) of the frame 2. In addition, a second flange portion 202 for pressing the first force applying mechanism 6 composed of a coil spring or the like described later is formed at the lower end of the second cylindrical portion 201. It should be noted that the second cylindrical portion 201 does not necessarily have to be cylindrical, and may also be prismatic, elliptical, or the like as long as it is suitable for supporting the second force applying mechanism 7 composed of a coil spring or the like described later.

[0055] [Sliding part]

[0056] A sliding portion 31 is slidably mounted on the inner circumferential surface of the frame 2, and a portion thereof protrudes to the outside from the opening of the frame 2. A circular opening 310 is formed at one end of the sliding portion 31 for allowing the second cylindrical portion 201 of the base 20 to slide freely therethrough, and a track-shaped opening 311 is formed at the other end for allowing the sensor portion 4 described later to slide freely therethrough.

[0057] [Hood]

[0058] The cover 30 is mounted on the portion of the slide 31 that protrudes from the opening of the frame 2 to the outside. The cover 30 and the slide 31 are detachably connected by providing a small circular recess 302 on the inner circumferential surface near the opening end of the cover 30 and providing a small hemispherical protrusion 312 that engages with the recess 302 on the side of the slide 31 that protrudes to the outside, thereby forming a measurement auxiliary unit 3 (see FIG. Figure 1 ).

[0059] The cover 30 is formed as a cylinder, which is open at the end on the side mounted on the sliding part 31, and has a flat track-shaped guide surface 300 formed at the end on the side pressed against the skin of the person being measured. In addition, a small track-shaped opening 301 for the front end 40 of the sensor part 4 to enter and exit is formed in the center of the guide surface 300. It should be noted that the shape of the guide surface 300 does not necessarily have to be a track shape, and can also be other common shapes such as a rectangle, a polygon, a circle, an ellipse, etc., as long as it can ensure an area suitable for guiding the pressing angle of the cover 30 relative to the skin surface of the person being measured to be a right angle by pressing against the skin of the person being measured.

[0060] In addition, in this embodiment, the cover 30 of the measurement auxiliary unit 3 is formed of a transparent or translucent material so that the sensor part 4 inside the cover 30 and the contact state between the sensor part 4 and the skin of the person being measured can be visually observed, but it does not necessarily have to be transparent or translucent and can also be opaque.

[0061] [Sensor unit]

[0062] Inside the cover 30 of the measurement auxiliary unit 3, the sensor part 4 is supported in the opening 311 of the sliding part 31 in a slidable manner. The sensor part 4 has a first cylindrical part 42 that is completely or partially hollow or solid at the end portion on one side mounted on the base 20, and has a flat track-shaped sensing surface at the front end 40 on the side pressed against the skin of the person being measured, and has a columnar shape with a track-shaped cross section as a whole. It should be noted that the first cylindrical part 42 mainly functions to support the first force applying mechanism 6 composed of a coil spring or the like described later, so it does not necessarily have to be cylindrical, and can also be a prism, an elliptical column, etc. as long as it is suitable for supporting the first force applying mechanism 6 and can be slidably engaged with the second cylindrical part 201 of the base 20.

[0063] In addition, in the skin condition measuring device 1 of the present embodiment, a switch 5 is installed on the base 20 of the frame 2, and the front end 40 of the sensor part 4 is moved toward the base 20 of the frame 2 to a specified position, and the rear end of the sensor part 4 blocks the light of the light-controlled switch, or presses the switch, thereby turning the switch 5 into an on state.

[0064] In the skin property measurement device 1 of the present embodiment, in order to measure the moisture content of the skin of the subject, the front end portion 40 of the sensor portion 4 is provided with electrodes 41 in a comb-tooth shape (see Figure 2 (c)). The electrode 41 is composed of a pair of positive and negative electrodes. In the present embodiment, three electrodes 41 are arranged in a horizontal row at the front end 40 of the sensor unit 4. Therefore, in the present embodiment, by enlarging the area of ​​the electrode 41, the influence of the difference in the local water content in the skin of the measured person is reduced, and the measurement accuracy of the water content is improved. In addition, by measuring the water content of the skin of the measured person at three points and averaging it, the influence of the spots of skin characteristics caused by the difference in the measurement site can be reduced, and the measurement accuracy of the water content can be improved.

[0065] The skin property measurement device 1 of this embodiment is suitable for a measurement device that requires accurate pressing angle and pressing force when measuring the properties of the skin, and the measurement object is not limited to the water content of the skin. For example, although not shown in the figure, the skin property measurement device 1 of this embodiment can also be provided with a vibration detection element in the sensor part 4, so that the front end 40 of the sensor part 4 vibrates at a predetermined frequency through the sensor part 4 and contacts the skin of the person being measured, and the vibration frequency before and after the contact is detected by the vibration detection element, and then the detected frequency is amplified by the control substrate, thereby being able to measure the elasticity of the skin based on the difference in frequency before and after the contact with the skin.

[0066] [First force-applying mechanism]

[0067] In the skin condition measurement device 1 of the present embodiment, the first cylindrical portion 42 of the sensor portion 4 is inserted inside the second cylindrical portion 201 of the base 20 in a slidable manner. In addition, the skin condition measurement device 1 of the present embodiment is provided with a first urging mechanism 6 for urging the sensor portion 4 in such a manner that the front end portion 40 of the sensor portion 4 is away from the sliding portion 31. In the present embodiment, a first coil spring 6 is used as the first urging mechanism 6, and the first coil spring 6 is arranged between the second flange portion 202 of the second cylindrical portion 201 of the base 20 and the upper end portion of the sensor portion 4 and around the first cylindrical portion 42 of the sensor portion 4, and is supported by the sensor portion 4 so as to be pressable.

[0068] It should be noted that, although not shown in the figure, in the present embodiment, by omitting the second flange portion 202 of the second cylindrical portion 201, the first cylindrical portion 42 of the sensor portion 4 can also be inserted slidably outside the second cylindrical portion 201 of the base 20. In this case, if the first coil spring 6 is disposed between the lower end portion of the second cylindrical portion 201 of the base 20 and the upper end portion inside the first cylindrical portion 42 of the sensor portion 4 and in the first cylindrical portion 42, it can be supported by the sensor portion 4 so as to be pressable.

[0069] [Second force applying mechanism]

[0070] In the skin condition measurement device 1 of the present embodiment, the second cylindrical portion 201 of the base 20 passes through the opening 310 at the upper portion of the sliding portion 31 in a slidable manner. In addition, the skin condition measurement device 1 of the present embodiment is provided with a second urging mechanism 7 for urging the sliding portion 31 of the measurement auxiliary unit 3 so as to move the guide surface 300 of the cover portion 30 of the measurement auxiliary unit 3 away from the frame 2. In the present embodiment, a second coil spring 7 is used as the second urging mechanism 7, and the second coil spring 7 is arranged between the first flange portion 200 of the second cylindrical portion 201 of the base 20 and the upper end portion of the sliding portion 31 of the measurement auxiliary unit 3 and around the second cylindrical portion 201 of the base 20, so as to be supported by the sliding portion 31 of the measurement auxiliary unit 3 so as to be pressable.

[0071] In the skin property measuring device 1 of the present embodiment, in order to simply support and compactly arrange the first coil spring 6 and the second coil spring 7, the central axis a of the first cylindrical portion 42 of the sensor portion 4 and the central axis b of the second cylindrical portion 201 of the base 20 are arranged on the same axis, and the central axis c of the opening portion 310 at the upper portion of the sliding portion 31 of the measurement auxiliary unit 3 and the central axis b of the second cylindrical portion 201 of the base 20 and the central axis a of the first cylindrical portion 42 of the sensor portion 4 are arranged on the same axis.

[0072] Therefore, the central axis (not shown) of the first coil spring 6 mounted around the first cylindrical portion 42 is also coaxially arranged with the central axis (not shown) of the second coil spring 7 mounted around the second cylindrical portion 201, thereby enabling the skin property measuring device 1 to be stored in an extremely compact handheld size.

[0073] It should be noted that, in the present embodiment, the materials used for the frame 2, the base 20, the cover 30, the sliding part 31, and the sensor part 4 are not particularly limited, and resin materials, metal materials, or composite materials formed by combining them can be used, but from the perspective of light weight, excellent formability, and excellent insulation, it is preferred to use a hard plastic material. In addition, in the present embodiment, the materials used for the first force applying mechanism 6 and the second force applying mechanism 7 are not particularly limited, and elastic metal materials or elastic resin materials, or composite materials formed by combining them can be used, but from the perspective of excellent durability, it is preferred to use elastic metal materials.

[0074] [Operation of the Skin Property Measurement Device]

[0075] exist Figure 3 , a cross-sectional view showing an operating state of a sensor unit 4 of a skin condition measurement device 1 to which an indicator 8 according to an embodiment of the present invention is applied is shown. Figure 3 (a) is a cross-sectional view of the sensor unit 4 in a standby state. Figure 3 (b) and Figure 3 (c) is a cross-sectional view of the sensor unit 4 in a contact state. Figure 3 (d) is a cross-sectional view of the sensor unit 4 in a measurement start state. Next, the operation of the skin condition measurement device 1 to which the indicator 8 according to one embodiment of the present invention is applied will be described.

[0076] (1) Standby mode

[0077] like Figure 3 As shown in (a), in the skin property measurement device 1 of the present embodiment, in a no-load state, that is, before the guide surface 300 of the cover 30 of the measurement auxiliary unit 3 is pressed against the skin 9 of the subject, the front end 40 of the sensor unit 4 is urged by the first urging mechanism (first coil spring) 6 to a position farthest from the base 20 of the frame 2 and the sliding portion 31 of the measurement auxiliary unit 3, and the guide surface 300 of the cover 30 is also urged by the second urging mechanism (second coil spring) 7 to a position farthest from the base 20 of the frame 2. At this time, the front end 40 of the sensor unit 4 having the electrode 41 is held in a state accommodated in the cover 30, so that the front end 40 of the sensor unit 4 is protected by the cover 30 from damage, etc., and malfunction caused by unexpected contact of the front end 40 is also prevented.

[0078] (2) Contact status with skin - 1

[0079] like Figure 3 As shown in (b), in the skin property measuring device 1 of the present embodiment, when the guide surface 300 of the cover portion 30 of the measurement auxiliary unit 3 is pushed against the skin 9 of the person being measured, initially only the guide surface 300 moves toward the base 20 of the frame 2, and then the guide surface 300 and the front end portion 40 of the sensor portion 4 move toward the base 20 of the frame 2.

[0080] As a result, in the skin property measurement device 1 of the present embodiment, before the front end portion 40 of the sensor unit 4 contacts the subject's skin 9, the guide surface 300 having a larger contact area than the front end portion 40 contacts the subject's skin 9, so that first, the cover portion 30 of the measurement auxiliary unit 3 is guided so that the pressing angle with respect to the subject's skin surface becomes a right angle, and then the front end portion 40 of the sensor unit 4 also contacts the subject's skin 9 while being guided by the cover portion 30 of the measurement auxiliary unit 3 so that the pressing angle with respect to the subject's skin surface becomes a right angle. Therefore, the skin property measurement device 1 of the present embodiment can measure the subject's skin property (skin moisture content) at an appropriate contact angle.

[0081] (3) Contact status with skin - 2

[0082] In the skin property measuring device 1 of the present embodiment, after the front end portion 40 of the sensor portion 4 comes into contact with the skin 9 of the person being measured, in other words, after the guide surface 300 of the cover portion 30 of the measurement auxiliary unit 3 is pressed against the skin 9 of the person being measured and the guide surface 300 and the front end portion 40 of the sensor portion 4 are moved toward the base 20 of the frame 2, the pressing force per unit area generated at the front end portion 40 of the sensor portion 4 is set to be the same as the pressing force per unit area generated at the guide surface 300, or to be greater than the pressing force per unit area generated at the guide surface 300.

[0083] Therefore, if Figure 3 As shown in (c), after the front end 40 of the sensor unit 4 contacts the skin 9 of the person being measured, if the guide surface 300 of the cover 30 of the measurement auxiliary unit 3 and the front end 40 of the sensor unit 4 are further pressed against the skin 9 of the person being measured, the sliding portion 31 of the measurement auxiliary unit 3 first moves toward the base 20 of the frame 2, reaches the sliding limit 313 and cannot move. As a result, after the sliding portion 31 reaches the sliding limit 313, only the front end 40 of the sensor unit 4 moves toward the base 20 of the frame 2.

[0084] In this way, after the tip 40 of the sensor unit 4 comes into contact with the skin 9 of the subject, and the guide surface 300 of the cover 30 of the measurement auxiliary unit 3 and the tip 40 of the sensor unit 4 move toward the base 20 of the frame 2, the skin 9 of the subject exposed in the opening 301 of the guide surface 300 is fixed by the edge of the opening 301, so that a uniform and constant elastic force is maintained. Therefore, the tip 40 of the sensor unit 4 can preferentially come into contact with the skin 9 of the subject maintained with a uniform and constant elastic force, regardless of the amount of depression (pressing force) of the guide surface 300, and can measure the skin properties (skin moisture content) with high accuracy.

[0085] (4) Measurement start status

[0086] like Figure 3 As shown in (d), in the skin condition measuring device 1 of the present embodiment, after the sliding portion 31 of the measurement auxiliary unit 3 reaches the sliding limit 313, when the front end portion 40 of the sensor portion 4 is further pushed against the skin 9 of the person being measured, the sensor portion 4 moves slightly toward the base 20 of the frame 2 and the sliding portion 31 of the measurement auxiliary unit 3, and at approximately the same time as reaching the sliding limit, the rear end portion of the sensor portion 4 blocks the light of the light-operated switch installed on the base 20 of the frame 2, or the switch 5 is turned on by pressing the switch, and the skin condition measuring device 1 starts measuring the skin condition (skin moisture content) of the person being measured.

[0087] As a result, in the skin property measurement device 1 of this embodiment, the front end portion 40 of the sensor portion 4 is guided so that the pressing angle is at right angles to the skin surface of the person being measured, and the switch 5 is turned on while the skin 9 of the person being measured is kept at a uniform and constant elastic force, and the measurement is started, so that the skin property (skin moisture content) can be measured accurately and stably. It should be noted that the measurement object of the skin property measurement device 1 of this embodiment is not limited to human skin (skin), and even the skin of animals can measure the skin properties such as moisture content.

[0088] <Indicator for measuring device>

[0089] exist Figure 4 , a cross-sectional view showing an operating state of an indicator 8 according to an embodiment of the present invention in the skin condition measurement device 1 is shown. Figure 4 (a) is a cross-sectional view of the sensor unit 4 in a standby state. Figure 4 (b) is a cross-sectional view of the sensor unit 4 in a contact state. Figure 4 (c) is a cross-sectional view of the sensor unit 4 in the measurement start state. Figure 1 , 24, the structure and operation of the indicator 8 according to one embodiment of the present invention in the skin condition measurement device 1 are described.

[0090] [Structure of indicator]

[0091] As reference Figure 2 As understood, the skin property measurement device 1 of the present embodiment includes an indicator 8 for displaying the relative position of the measurement auxiliary unit 3 (the cover portion 30 and the sensor portion 4) with respect to the frame 2 on the side surface of the frame 2. The indicator 8 includes: a window portion 80 opened on the side surface of the frame 2; a first display portion 81 slidably supported inside the window portion 80; and a second display portion 82 adjacent to the first display portion 81 and supported so as to be slidable in the same direction as the first display portion 81.

[0092] The first display unit 81 is a long and thin rod-shaped member, and is directly and integrally connected to the sliding portion 31 of the measurement auxiliary unit 3 via the first connecting member 810. Therefore, in the present embodiment, the sliding direction and sliding amount of the first display unit 81 are configured to coincide with the sliding direction and sliding amount of the cover portion 30 and the sliding portion 31 of the measurement auxiliary unit 3.

[0093] In addition, in the first display portion 81, the surface of the side exposed from the window portion 80 is color-divided into: a first colored area 811, which is colored with a first display color indicating that the cover portion 30 of the measurement auxiliary unit 3 is in a position (first position) in the standby state relative to the frame 2; and a second colored area 812, which is colored with a second display color indicating that the cover portion 30 of the measurement auxiliary unit 3 is in a position (second position) in a state of reaching the sliding limit 313 relative to the frame 2. It should be noted that, according to the characteristics of the measuring device to which the indicator 8 is applied, when there are three or more positions of the state to be displayed, the first display portion 81 may be color-divided according to the number of the positions. In addition, the type of the first and second areas may be differentiated not only by display colors but also by patterns or a combination thereof.

[0094] In addition, the first display unit 81 does not necessarily need to be directly and integrally connected to the sliding unit 31, and may be indirectly connected, for example, by using other connecting members (not shown) using the principle of a lever, so as to enlarge or reduce the sliding amount of the measurement auxiliary unit 3. In addition, the first display unit 81 only needs to be connected to the measurement auxiliary unit 3, and may be a separate component from the cover 30 and the sliding unit 31.

[0095] The second display unit 82 is also a long and thin rod-shaped member, and is directly and integrally connected to the sensor unit 4 via the second connecting member 820. Therefore, in this embodiment, the sliding direction and sliding amount of the second display unit 82 are configured to match the sliding direction and sliding amount of the sensor unit 4.

[0096] In addition, in the second display portion 82, the surface of the side exposed from the window portion 80 is color-divided into: a third coloring area 821, which is colored with a third display color indicating that the sensor portion 4 is in the position (third position) of the frame 2 in the standby state; and a fourth coloring area 822, which is colored with a fourth display color indicating that the sensor portion 4 is in the position (fourth position) of the frame 2 in the measurement start state. It should be noted that, according to the characteristics of the measurement device to which the indicator 8 is applied, when there are three or more positions of the state to be displayed, the second display portion 82 may be color-divided according to the number of the positions. In addition, the type of the third and fourth areas may be differentiated not only by display colors but also by patterns or a combination thereof.

[0097] In addition, the second display unit 82 does not necessarily have to be directly and integrally connected to the sensor unit 4, and may be indirectly connected, for example, by using other connecting members (not shown) that utilize the principle of a lever, so as to enlarge or reduce the sliding amount of the sensor unit 4. In addition, the second display unit 82 only needs to be connected to the sensor unit 4, and may also be a separate component from the sensor unit 4.

[0098] The indicator 8 of this embodiment is not limited to the measuring device 1 for measuring skin properties such as moisture content and elasticity, and can be applied to other measuring devices as long as two or more movable parts that can be separated and moved independently are provided, such as the measurement auxiliary unit 3 (cover part 30 and sliding part 31) and the sensor part 4. In addition, when there are three or more movable parts, a display part can be provided according to the number of movable parts.

[0099] As described above, the indicator 8 of this embodiment is applicable to any measuring device that includes at least the frame 2 , the measurement auxiliary unit 3 slidably supported by the frame 2 , and the sensor unit 4 slidably supported by the measurement auxiliary unit 3 .

[0100] It should be noted that in the present embodiment, the materials used for the first display portion 81, the first connecting member 810, the second display portion 82, and the second connecting member 820 of the indicator 8 are not particularly limited, and resin materials, metal materials, or composite materials formed by combining them can be used, but from the perspective of light weight and excellent formability, it is preferred to use hard plastic materials.

[0101] [Indicator Movement]

[0102] (1) Standby mode

[0103] like Figure 4 As shown in (a), in the skin property measurement device 1 of the present embodiment, in the no-load state, that is, before the cover 30 of the measurement auxiliary unit 3 is pressed against the skin 9 of the subject, the cover 30 of the measurement auxiliary unit 3 is located at the first position farthest from the frame 2, and the first display unit 81 connected to the sliding portion 31 of the measurement auxiliary unit 3 displays a first colored area 811 of a first display color indicating that the cover 30 of the measurement auxiliary unit 3 is located at the first position in the window 80. On the other hand, the sensor unit 4 is also located at the third position farthest from the frame 2, and the second display unit 82 connected to the sensor unit 4 displays a third colored area 821 of a third display color indicating that the sensor unit 4 is located at the third position in the window 80.

[0104] As a result, a combination of the first colored area 811 and the third colored area 821 indicating that the sensor unit 4 is in the standby state is displayed in the window 80 of the skin condition measurement device 1, so the user can easily understand that the sensor unit 4 is in the standby state by visual observation.

[0105] (2) Contact status with skin

[0106] like Figure 4 As shown in (b), in the skin property measurement device 1 of the present embodiment, when the cover 30 of the measurement auxiliary unit 3 is further pressed against the skin 9 of the person being measured, the sliding portion 31 of the measurement auxiliary unit 3 moves toward the base 20 of the frame 2 and reaches the second position as the sliding limit 313. Therefore, the first display portion 81 connected to the sliding portion 31 of the measurement auxiliary unit 3 displays the second colored area 812 in the window portion 80 indicating that the cover 30 of the measurement auxiliary unit 3 has reached the second position.

[0107] On the other hand, the sensor unit 4 is held at the third position farthest from the frame 2, and the cover 30 of the measurement auxiliary unit 3 is relatively retreated relative to the sensor unit 4, thereby contacting the subject's skin 9. Therefore, the second display unit 82 connected to the sensor unit 4 displays a third colored area 821 of the third display color in the window 80 indicating that the sensor unit 4 is held at the third position.

[0108] As a result, a combination of a second colored area 812 of a second display color indicating that the sensor part 4 is in contact with the skin 9 of the person being measured and a third colored area 821 of a third display color is displayed in the window portion 80 of the skin condition measuring device 1, so that the user can easily and accurately grasp by visual inspection that the sensor part 4 is in contact but measurement has not started.

[0109] (3) Measurement start status

[0110] like Figure 4 As shown in (c), in the skin property measuring device 1 of the present embodiment, when the cover portion 30 of the measurement auxiliary unit 3 is further pushed against the skin 9 of the person being measured, the sliding portion 31 of the measurement auxiliary unit 3 is maintained at the second position serving as the sliding limit 313, so that the first display portion 81 connected to the sliding portion 31 of the measurement auxiliary unit 3 displays a second colored area 812 of the second display color in the window portion 80 indicating that the cover portion 30 of the measurement auxiliary unit 3 is maintained at the second position.

[0111] On the other hand, the sensor unit 4 moves toward the base 20 of the frame 2, and at about the same time as reaching the fourth position as the sliding limit, the rear end of the sensor unit 4 blocks the light of the light-operated switch mounted on the base 20 of the frame 2, or presses the switch to turn on the switch 5. Therefore, the second display unit 82 connected to the sensor unit 4 displays a fourth colored area 822 of the fourth display color in the window 80, indicating that the sensor unit 4 has reached the fourth position and turned on the switch 5.

[0112] As a result, the combination of the second colored area 812 and the fourth colored area 822 indicating that the measurement of the subject's skin condition (skin moisture content) has started by turning on the switch 5 by the sensor unit 4 is displayed in the window 80 of the skin condition measurement device 1, so the user can easily and accurately understand by visual observation that the sensor unit 4 has contacted the subject's skin 9 and the measurement has started. It should be noted that when the second display unit 83 in the window 80 simultaneously displays the third colored area 821 and the fourth colored area 822 (the boundary between the third colored collar 821 and the fourth colored collar 822), the user can easily understand that the sensor unit 4 has not been fully pressed to the correct position and the appropriate pressing force.

[0113] Thus, the indicator 8 for the skin property measurement device according to one embodiment of the present invention includes the first display unit 81 for displaying the operation of the measurement auxiliary unit 3 and the second display unit 82 for displaying the operation of the sensor unit 4, respectively. Thus, the positions of the measurement auxiliary unit 3 and the sensor unit 4 can be easily and accurately grasped by visual inspection, and human measurement errors caused by poor pressing of the cover 30 of the measurement auxiliary unit 3 and the sensor unit 4 can be prevented in advance. For example, when the measurement is not started due to insufficient pressing of the measurement auxiliary unit 3 and the sensor unit 4, the user can easily recognize the reason for not starting the measurement (insufficient pressing). In addition, the first display unit 81 and the second display unit 82 are mechanically linked to the measurement auxiliary unit 3 and the sensor unit 4, so they also have the advantages of simple structure, no need for power supply, and extremely high reliability.

[0114] Furthermore, according to the indicator 8 for the skin condition measuring device of the present embodiment, a first display portion 81 directly connected to the measurement auxiliary unit 3 and distinguished by at least two different colors, and a second display portion 82 directly connected to the sensor portion 4 and distinguished by at least two different colors are displayed in a window portion 80. Therefore, multiple states of the skin condition measuring device 1 can be easily identified by the display of colors and their combination, and human measurement errors caused by poor pressing of the cover portion 30 of the measurement auxiliary unit 3 and the sensor portion 4 can be more reliably prevented.

[0115] In particular, in the indicator 8 of the present embodiment, when the sensor section 4 is pressed obliquely against the skin 9 of the person being measured, the guide surface 300 of the cover 30 of the measurement auxiliary unit 3 becomes an obstacle, and the front end 40 of the sensor section 4 cannot contact the skin 9 of the person being measured, or at least cannot move to a state where the switch 5 is turned on. Therefore, the display in the window 80 does not advance to the combination of the second colored area 812 and the fourth colored area 822, and the user can be accurately informed that the sensor section 4 is not properly pressed.
