The detection result of the pulse wave sensor 30 is input to the control unit 5 of the watch case 11.

FIG. 3 is a cross-sectional view of the pulse wave sensor 30.
A circuit board 35 is disposed inside the case body of the pulse wave sensor 30, and an LED 31, a phototransistor 32, and other electronic components are mounted on the circuit board 35. The pulse wave sensor 30 includes a light transmission window formed on the upper surface portion of the sensor frame 36 by a light transmission plate 34 made of a glass plate. The LED 31 and the phototransistor 32 have the light emitting surface and the light receiving surface directed toward the light transmitting plate 34, respectively. For this reason, the outer surface 441 of the translucent plate 34.
When the LED 31 emits light toward the surface side of the finger T with the surface of the finger T in close contact with the
The phototransistor 32 receives the light reflected from the user's finger T among the light emitted from the LED 31.

In this embodiment, an InGaN (indium-gallium-nitrogen) blue LED is used as the LED 31, and the emission spectrum has an emission peak at 450 nm. Furthermore, the emission wavelength region of the LED 31 is in the range from 350 nm to 600 nm.
In the present embodiment, a GaAsP (gallium-arsenic-phosphorus) phototransistor is used as the phototransistor 32 in correspondence with the LED 31 having such light emission characteristics. The light receiving wavelength region of the phototransistor 32 itself has a main sensitivity region of 300 nm to 60 nm.
There is a sensitivity region within the range of 0 nm and 300 nm or less.

When the pulse wave sensor 30 configured as described above is brought into close contact with the finger T by the sensor mounting supporter 40 and light is emitted from the LED 31 toward the finger T in this state, the light is transmitted to the finger T.
Part of the light is absorbed and part of the light is reflected by hemoglobin in the blood. The light reflected from the blood vessel of the finger T is received by the phototransistor 32, and the change in the amount of received light corresponds to the change in blood volume (blood pulse wave). That is, when the blood volume is large, the reflected light becomes weak, while when the blood volume decreases, the reflected light becomes strong. Therefore, if a change in the reflected light intensity is detected, various biological information including the pulse rate can be measured.

In order to accurately measure the pulse, the pulse wave sensor 30 is supported by the sensor mounting supporter 40.
It is necessary for the finger T to be in close contact with the finger T so that external light does not enter the pulse wave sensor 30. In the sensor mounting supporter 40, the pulse wave sensor 30 can be brought into close contact with two locations, and the user can select an arrangement location suitable for pulse measurement as required.
The location of the pulse wave sensor 30 suitable for measuring the pulse is a hairless part that does not interfere with the detection of the pulse wave sensor 30, or a place that is not a hairy part of the hairy part. The sensor mounting supporter 40 can bring the pulse wave sensor 30 into close contact with the abdominal surface U (palm side) of the finger T and the side surface S of the finger T.

FIG. 4 is a perspective view of the sensor mounting supporter 40 when the pulse wave sensor 30 is mounted on the ventral surface U. FIG.
The sensor mounting supporter 40 includes a finger mounting body 41 configured in a cylindrical shape, and a fixed band 50 for fixing the pulse wave sensor 30 is attached to the inside thereof. 1 and 4
As shown in FIG. 3, on the base side of the finger T of the finger attachment body 41, there are a first tongue portion 46 projecting beyond the base on the back side of the hand and a second tongue portion 47 projecting beyond the base on the palm side. Is formed.
When the pulse wave sensor 30 is attached to the ventral surface U, the pulse wave sensor 30 is connected to the pulse wave sensor 30.
The fixing band 5 in which the cable 20 is positioned on the extended line of the second tongue 47 on the second tongue 47 side.
It is fixed to the finger mounting body 41 so as to be sandwiched between the zero abdominal band portions 54. The sensor mounting supporter 40 is fitted around the finger T. When the sensor mounting supporter 40 is mounted on the finger T, the pulse wave sensor 30 comes into close contact with the ventral surface U.

FIG. 5 is a perspective view of the sensor mounting supporter 40 when the pulse wave sensor 30 is mounted on the side surface S. FIG.
The side band portion 55 that can fix the pulse wave sensor 30 so as to be in close contact with the side surface S of the finger T is provided at a position that is approximately 90 ° different from the abdominal surface band portion 54 in a state where the finger mounting body 41 is mounted on the finger T. ing. When the pulse wave sensor 30 is attached to the side surface S, the pulse wave sensor 30 is configured such that the cable 20 of the pulse wave sensor 30 is sandwiched between the side band portions 55 and the finger attachment body 41.
It is fixed to. The sensor mounting supporter 40 is fitted around the finger T, and the pulse wave sensor 30 comes into close contact with the side surface S when the sensor mounting supporter 40 is mounted on the finger T.
Further, as shown in FIG. 1, since the first tongue portion 46 and the second tongue portion 47 project to the base side of the finger T, the first tongue portion 46 and the second tongue portion 47 are rotated in the direction rotating around the finger T with respect to the sensor mounting supporter 40. When force is applied, the first tongue portion 46 or the second tongue portion 47 is caught by the crotch portion T1 of the finger T, and rotation is prevented. Thereby, since the pulse wave sensor 30 stably adheres to a predetermined position, the pulse can be accurately measured.

Furthermore, the finger T is an index finger of the left hand, and the side band part 55 and the pulse wave sensor 30 are
It is disposed at a position corresponding to the side surface of the left hand on the thumb side. As a result, the short thumb is
Since the pulse wave sensor 30 in close contact with the side surface S of the index finger is less likely to interfere from the outside of the sensor mounting supporter 40, it is possible to prevent the pulse measurement from being disturbed by interference between other fingers and the pulse wave sensor 30. . Here, the finger T may be the thumb or the little finger of the left hand. When the sensor mounting supporter 40 is mounted on the thumb of the left hand, the side band portion 55 is connected to the side band portion 55.
In this case, the pulse wave sensor 30 is in close contact with either one of both side surfaces of the thumb. Further, when the sensor mounting supporter 40 is mounted on the little finger of the left hand, the side band portion 55 is not provided, and another side band is provided at a position facing the side band portion 55 shown in FIG. The pulse wave sensor 30 is in close contact with the outer side surface of the little finger.
As described above, even when the sensor mounting supporter 40 is mounted on either the thumb or the little finger, the pulse wave sensor 30 is brought into close contact with a position where the other adjacent fingers and the pulse wave sensor 30 are unlikely to interfere with each other. It is possible to prevent the pulse measurement from being disturbed by interference between the other fingers and the pulse wave sensor 30.

FIG. 6 is a development view of the sensor mounting supporter 40.
The sensor mounting supporter 40 is formed by sewing a stretchable cloth-like supporter material 41 a to form a cylindrical finger mounting body 41, and the finger mounting body 41 includes a fixing band 50. The surface visible in FIG. 6 is the inner side surface 41 of the sensor mounting supporter 40 that contacts the finger T.
b. The supporter material 41 a is formed in a substantially trapezoidal shape, and has a linear upper side 43, a lower side 42 formed in a curve, and left and right end sides 44 connecting the upper side 43 and the lower side 42. The left and right end sides 44 extending from the lower side 42 to the upper side 43 extend so as to taper toward the upper side 43, and are configured symmetrically about the substantially trapezoidal center line C as an axis. The sensor mounting supporter 40 is formed in a cylindrical shape by sewing the end sides 44 together. Also,
A sealing tape (not shown) is affixed to the inside of the stitched portion (not shown) of the edge 44,
The seam is not exposed on the inner surface 41b of the sensor mounting supporter 40. Furthermore, the finger mounting body 41 formed in a cylindrical shape has a tapered taper that matches the shape of the finger T, and has high adhesion to the finger T.
Further, the supporter material 41a is a material having particularly high elasticity in the direction indicated by the arrow A in FIG. 6, and the thickness of the finger T in a state where the tubular finger attachment body 41 is formed by stitching. Can extend greatly in the direction of. For this reason, the sensor mounting supporter 40 can be mounted corresponding to fingers T of various thicknesses. Further, the pulse wave sensor 30 can be reliably brought into close contact with the finger T by the elastic force in the contraction direction.

Since the lower side 42 is formed to draw a sine curve-like curve, the length of the supporter material 41a differs depending on the position in the width direction. That is, the length of the supporter material 41a is the shortest at both ends 44 and the center in the width direction (the position indicated by the symbol C in the figure)
In the intermediate position, the length of the supporter material 41a is the longest. Therefore, the lower side 42 has
Two extended portions that are curved and project in a tongue shape are formed, and a curved concave portion 45 is formed between the two extended portions. The extension portions at the two locations are the first tongue portion 46 protruding from the base end portion of the sensor mounting supporter 40, respectively, when the cylindrical sensor mounting supporter 40 is created by sewing the end sides 44, and The second tongue 47 is formed. The first tongue portion 46 and the second tongue portion 47 are in positions facing each other, and the length of the sensor mounting supporter 40 is the shortest between the first tongue portion 46 and the second tongue portion 47. A recess 45 is formed. The recessed portions 45 are formed at two locations between the first tongue portion 46 and the second tongue portion 47 in a state in which the cylindrical sensor mounting supporter 40 is configured.

A band-shaped fixed band 50 is attached to the inner side surface 41b of the supporter material 41a above the lower side 42 and substantially parallel to the upper side 43. The fixed band 50 is a single elastic rubber band.
Both ends and the center of the fixing band 50 are fixed to the inner side surface 41 b to form a fixing portion 51. The fixed band 50 has two portions between the fixed portion 51 at the both ends and the central fixed portion 51 that can be freely expanded and contracted. These two portions are the abdominal surface band portion 54 and the side surface band portion. 55 is constituted. That is, the abdominal surface band portion 54 and the side surface band portion 55 are configured by fastening the same fixing band 50 with a plurality of fixing portions 51. The pulse wave sensor 30 is fixed so that the cable 20 is sandwiched between the abdominal surface band portion 54 and the side surface band portion 55 and the inner side surface 41b.
Further, the width of the abdominal surface band portion 54 and the side surface band portion 55 is formed smaller than the size of the pulse wave sensor 30. For this reason, when fixing the pulse wave sensor 30, the abdominal surface band portion 54 and the side surface band portion 55 are deformed by being pulled, and the pulse wave sensor 30 is passed through the inside thereof. According to this, since the abdominal surface band portion 54 and the side surface band portion 55 sandwich the cable 20 in a state of being contracted to the original size, the pulse wave sensor 30 is prevented from being detached from the abdominal surface band portion 54 and the side surface band portion 55. Is done.

The center of the abdominal surface band portion 54 is located on a straight line extending from the apex of the second tongue portion 47 in parallel with the center line C, and the center of the side band portion 55 is on the center line C extending from the apex of the recess 45. Is located. Further, the center of the abdominal surface band portion 54 and the center of the side surface band portion 55 are in a positional relationship that differs by approximately 90 ° in the inner circumferential direction of the finger mounting body 41 when the finger mounting body 41 is mounted on the finger T.
That is, the second tongue portion 47 is attached so as to be positioned on the palm side of the finger T, and the pulse wave sensor 30 is brought into close contact with the abdominal surface U of the finger T by the abdominal surface band portion 54 on the extension line. It is attached. Further, the pulse wave sensor 30 is attached in close contact with the side surface S of the finger T by the side band portion 55 disposed at a position approximately 90 ° different from the abdominal surface band portion 54.

FIG. 7 is a partially broken side view when the pulse wave sensor 30 is brought into close contact with the ventral surface U. FIG. FIG.
These are side views when the pulse wave sensor 30 is brought into close contact with the side surface S. FIG.
As shown in FIG. 7, the pulse wave sensor 30 is fixed in position on the abdominal surface U by the abdominal surface band portion 54 and is in close contact with the abdominal surface U so as to be pressed by the finger attachment body 41.
As shown in FIG. 8, the pulse wave sensor 30 is fixed to the side surface S by the side band portion 55 and is in close contact with the side surface S so as to be pressed by the finger mounting body 41.
The measurement of the pulse by the pulse wave sensor 30 can be satisfactorily performed on both the abdominal side U and the side S as long as the finger T is extended. However, for example, when the pulse is measured while the user holds the hand, the finger T is bent, so that the abdominal side U and the side S are deformed as the finger T is bent. In this case, since the deformation amount of the ventral surface U is relatively large, the pulse wave sensor 30 is lifted with the deformation of the ventral surface U, and the pulse wave sensor 30 is moved to the ventral surface U.
There is a risk that it will not be able to adhere to. On the other hand, since the deformation amount of the side surface S is relatively small, even when the finger T is bent, the pulse wave sensor 30 can be kept in close contact with the side surface S, and the pulse can be accurately measured.
As described above, according to the sensor mounting supporter 40, the user can select an arrangement location of the pulse wave sensor 30 suitable for measuring a pulse as necessary.
Further, the ventral side U and side S of the finger T are in close contact with the outer surface 441 of the pulse wave sensor 30,
In this state, the pulse wave is detected when the phototransistor 32 receives the light reflected from the finger T among the light emitted from the LED 31.

As described above, according to the first embodiment to which the present invention is applied, the pulse wave sensor 30 for detecting biological information is fixed by the side band portion 55 provided inside the finger wearing body 41, In a state where the sensor mounting supporter 40 is mounted on the finger T, the pulse wave sensor 30 is in close contact with the skin on the side surface S of the finger T. The side surface S has a relatively small deformation amount on the surface of the finger T even when the user bends the finger T, and the pulse wave sensor 30 is kept in close contact with the side surface S. Can be brought into close contact with the finger T. Therefore, the pulse wave sensor 30 can be reliably brought into close contact with the finger T even when the user extends the finger T, bends it, or moves the finger T. Regardless of this, the pulse wave sensor 30 can be reliably brought into close contact with the finger T to accurately measure biological information.
Moreover, since the abdominal surface band part 54 which can fix the pulse wave sensor 30 so that it may closely_contact | adhere to the abdominal surface U of the finger T is provided, the user can connect the pulse wave sensor 30 to the abdominal surface U or the side surface. It can be adhered to either of S. According to this, the user can bring the pulse wave sensor 30 into close contact with a position suitable for the measurement of biological information as necessary, and the biological wave information can be accurately obtained by making the pulse wave sensor 30 firmly attached to the finger T. Can be measured.
Further, the abdominal surface band portion 54 and the side surface band portion 55 are integrally configured by the same fixed band 50, and assembling is easy and the number of parts is reduced, so that the cost can be reduced.

Further, since the pulse wave sensor 30 is fixed to the abdominal surface band portion 54 and the side surface band portion 55 provided at positions different from each other by approximately 90 °, the pulse wave sensor is located at a position facing the abdominal surface U and the side surface S. 30 can be brought into close contact with each other, and the pulse wave sensor 30 can be reliably brought into close contact with the finger T to accurately measure biological information.
Also, the finger attachment body 41 is positioned by the first tongue portion 46 and the second tongue portion 47 being hooked on the crotch portion T <b> 1 and acting as a detent for the finger attachment body 41. As a result, the abdominal surface band 54
Alternatively, the pulse wave sensor 30 fixed to the side band portion 55 can be brought into close contact with a predetermined position of the finger T. Further, since the rotation of the finger mounting body 41 is prevented, the contact state of the pulse wave sensor 30 to the finger T can be maintained, so that the biological information can be accurately measured by reliably bringing the pulse wave sensor 30 into close contact with the finger T. . Furthermore, since the abdominal surface band portion 54 is provided on the second tongue portion 47 side,
If the finger mounting body 41 is mounted at a predetermined position, the pulse wave sensor 30 comes into close contact with the ventral surface U. Further, since the side band portion 55 is provided at a position that is approximately 90 ° different from the abdominal surface band portion 54, the pulse wave sensor 30 faces the side surface S in close contact when the finger mounting body 41 is mounted at a predetermined position. To do. Therefore, if the finger wearing body 41 is worn at a predetermined position, the pulse wave sensor 30 is brought into close contact with the abdominal surface U or side S, so that the user can easily bring the pulse wave sensor 30 into close contact. The biometric information can be accurately measured by securely bringing the sensor 30 into close contact with the finger T.

The pulse wave sensor 30 is in close contact with any one of the side surface S corresponding to the side surface on the thumb side of the index finger, at least one side surface of the thumb, and the side surface outside the little finger. These positions are positions where other adjacent fingers are unlikely to interfere with the pulse wave sensor 30 fixed to the inner side surface of the finger mounting body 41. According to this, since the pulse wave sensor 30 can be prevented from moving due to interference with other adjacent fingers, the pulse wave sensor 30 is securely brought into close contact with the fingers and biological information is accurately measured. it can.

The first embodiment shows an aspect to which the present invention is applied. The present invention is not limited to the first embodiment.
It is not limited to the embodiment. For example, in the first embodiment, the sensor mounting supporter 40 has been described as including the side band portion 55 and the abdominal surface band portion 54 at positions corresponding to the fingers T of the left hand, but the present invention is not limited thereto.

Moreover, in 1st Embodiment, although the supporter 40 for sensor mounting demonstrated the structure provided with the side surface band part 55 and the abdominal surface band part 54, this invention is not limited to this, The side surface band part 55 It is good also as a structure provided only with. Further, in the first embodiment, the side band portion 55 and the abdominal band portion 54 are approximately 9 in a state where the finger mounting body 41 is mounted.
Although the configuration provided at a position different by 0 ° has been described, the present invention is not limited to this, and the angle is different from 90 ° unless the pulse wave sensor 30 deviates significantly from the side surface S of the finger T. Also good. Of course, other detailed configurations can be arbitrarily changed.

[Second Embodiment]
Next, a second embodiment will be described.
The sensor mounting supporter 140 described in the second embodiment is different from the first embodiment in that two opposing side band portions 155 are provided. Here, the sensor mounting supporter 140 is fixed so that the pulse wave sensor 30 is in close contact with the finger T instead of the sensor mounting supporter 40 of the first embodiment. Note that, in the second embodiment, portions that are configured in the same manner as in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

FIG. 9 is a perspective view of the sensor mounting supporter 140.
The sensor mounting supporter 140 includes a finger mounting body 141 configured in a cylindrical shape, and a fixed band 150 for fixing the pulse wave sensor 30 is provided inside thereof. In addition, finger wearing body 1
A first tongue portion 146 that protrudes beyond the base of the back of the hand and a second tongue portion 147 that extends beyond the base of the palm side are formed on the base side of the 41 finger T.
The fixing band 150 is provided at a position approximately 90 ° different from the abdominal surface band portion 154 in a state where the abdominal surface band portion 154 provided on the second tongue portion 147 side and the finger attachment body 141 are attached to the finger T. There are two side band portions 155. The side band portions 155 are provided to face each other.
When the sensor mounting supporter 140 is mounted at a predetermined position on the finger T, the abdominal surface band 1
54 is located on the ventral surface U, one side band part 155 is located on the left side S of the finger T, and the other side band part 155 is located on the right side S. Therefore, the user can bring the pulse wave sensor 30 into close contact with any position of the ventral surface U, the left side surface S, and the right side surface S.

FIG. 10 is a development view of the sensor mounting supporter 140.
The sensor mounting supporter 140 is formed by sewing a stretchable cloth-shaped supporter material 141 a to form a cylindrical finger mounting body 141, and the finger mounting body 141 includes a fixing band 150. The surface visible in FIG. 10 is a sensor mounting supporter 14 that comes into contact with the finger T.
It is 0 inner surface 141b. The supporter material 141 a is formed in a substantially trapezoidal shape, and has a linear upper side 143, a lower side 142 formed in a curve, and left and right end sides 144 connecting the upper side 143 and the lower side 142. Further, the left and right end sides 144 extending from the lower side 142 to the upper side 143 extend so as to taper toward the upper side 143, and are configured symmetrically about the substantially trapezoidal center line C as an axis. The sensor mounting supporter 140 is formed in a cylindrical shape by sewing the end sides 144 together. Further, a sealing tape (not shown) is affixed to the inner side of the stitched portion (not shown) of the end side 144, and the inner side surface 1 of the sensor mounting supporter 140.
No seam is exposed at 41b. Furthermore, the finger mounting body 141 formed in a cylindrical shape has a tapered taper that matches the shape of the finger T, and has high adhesion to the finger T.
Further, the supporter material 141a is a material having particularly high elasticity in the direction indicated by the arrow A in FIG. 10, and in the state where the tubular finger attachment body 141 is formed by stitching, the finger T
Can greatly extend in the direction of the thickness. For this reason, since the finger mounting body 141 can be mounted corresponding to fingers T of various thicknesses, the sensor mounting supporter 140 can be mounted on any of the 5 fingers. Further, the pulse wave sensor 30 can be reliably brought into close contact with the finger T by the elastic force in the contraction direction.

Since the lower side 142 is formed to draw a sine curve-like curve, the length of the supporter material 141a differs depending on the position in the width direction. That is, both ends 144
At the center in the width direction (the position indicated by symbol C in the figure), the length of the supporter material 141a is the longest, and the length of the supporter material 141a is the shortest at the intermediate position. Therefore, the curved recess 145 is formed in two places on the lower side 142, and an extension that is curved and protrudes in a tongue shape is formed between the two recesses 145. In 144, a divided extension portion is formed. When the end sides 144 are stitched together, the divided extension portions are integrated to form an extension portion that protrudes in a tongue shape. The extension portions at these two locations are the first tongue portion 146 protruding from the base end portion of the sensor mounting supporter 140 when the cylindrical sensor mounting supporter 140 is created by sewing the end sides 144, and The second tongue 147 is formed.
The first tongue portion 146 and the second tongue portion 147 are in positions facing each other, and the first tongue portion 146
A recess 145 is formed between the first tongue 147 and the second tongue 147 so that the sensor mounting supporter 140 is the shortest. The recessed portions 145 are formed at two locations between the first tongue portion 146 and the second tongue portion 147 in a state where the cylindrical sensor mounting supporter 140 is configured.

The upper side 143 is located above the lower side 142 on the inner side surface 141b of the supporter material 141a.
A belt-like fixed band 150 is attached substantially in parallel with. The fixed band 150 is a single elastic rubber band.
The fixed band 150 is fixed to the inner side surface 141b at two positions at both ends and two positions at the center to form a fixed portion 151. The fixing band 150 is provided between the adjacent fixing portions 151.
The part of the part is a part that can freely expand and contract, and these three parts are the abdominal surface band part 1
54 and two side band portions 155 are formed. That is, the abdominal surface band portion 154 and the side surface band portion 155 are configured by fastening the same fixing band 150 with a plurality of fixing portions 151.
Further, the center of the abdominal surface band portion 154 is a center line C extending overlapping the apex of the second tongue portion 147.
Further, the center of each side band portion 155 is located on a straight line extending from each vertex of the recess 145 in parallel with the center line C.

As described above, according to the second embodiment to which the present invention is applied, the finger mounting body 141 is provided with the two side band portions 155 facing each other. Regardless of the direction of the side surface, the pulse wave sensor 30 can be freely arranged and brought into close contact with the side surface of the user's desired finger. In addition, since there is no need to distinguish between the left hand and the right hand, one sensor mounting supporter 140 can be used for fingers of both hands, and the biological information can be accurately measured by ensuring that the pulse wave sensor 30 is in close contact with the fingers.

In the first and second embodiments, the sensor mounting supporters 40 and 140 are
Although described as what is positioned by the 1st tongue part 46,146 and the 2nd tongue part 47,147, this invention is not limited to this, For example, the 1st tongue part 46,146 and 2nd
It is sufficient that at least one of the tongue portions 47 and 147 is formed. In the case where only one of the tongue portions is formed, the sensor mounting supporters 40, 1
40 is positioned by one tongue, and the tongue protrudes and abuts on the base of the back of the hand or the base of the palm. In order to prevent rotation of the sensor mounting supporters 40 and 140, it is desirable that there are two tongue portions. However, even with one tongue portion, since the tongue portion protrudes and contacts the base of the finger, Effective in preventing rotation. In particular, in the second embodiment, the sensor mounting supporter 140 can be mounted on any finger. For example, when mounted on the middle finger, the crotch portion of the adjacent finger is located on both sides of the tongue, so that one tongue Even so, a sufficient anti-rotation effect can be obtained. Further, when the first tongue portions 46 and 146 and the second tongue portions 47 and 147 are positioned at two positions, the first tongue portions 46 and 146 are no matter which direction the sensor mounting supporters 40 and 140 are rotated. Further, since at least one of the second tongue portions 47 and 147 is caught by the crotch portion of the finger, the rotation is prevented. In this case, for example, rotation can be prevented even if the sensor mounting supporters 40 and 140 are placed on the little finger having only one crotch portion of the adjacent finger.
Moreover, in the said 1st and 2nd embodiment, although demonstrated as what displays a pulse rate as biological information, this invention is not limited to this, For example, body temperature as biological information,
Blood pressure, pulse wave, arterial oxygen saturation, body movement, etc. may be displayed. Supporter material 4
The sewing locations in 1a and 141a may be positions where they do not overlap with the fixing bands 50 and 150, and it is needless to say that other detailed configurations can be arbitrarily changed.
