Description

[Technical field]

[0001] The present invention relates to a measuring device with a handle. [Background technology]

[0002] Measuring devices that use laser light have been known for some time, and are used in a variety of cases, such as receiving reflected light of an emitted laser light to obtain spatial position information of an object, or directing laser light at an object to determine reference surfaces and reference lines in civil engineering and construction. Because it is important that the measuring device is horizontal and vertically level, a tripod is often used, and the measurer places the measuring device on the tripod by holding the handle attached to the device, and then fixes the tripod and the measuring device in place.

[0003] Since it is necessary to fix a heavy measuring device on a tall tripod, a measuring device that is easy to hold has been proposed. For example, the handle of the measuring device in Patent Document 1 is composed of a grip part to be held by the fingers and a support arm part that supports the grip part by attaching it to a housing, and a curved part that matches the shape of the thumb is formed on the upper surface of the support arm part. In this way, the surveying instrument can be easily held by gripping the handle with four fingers excluding the thumb, supporting the support arm part with the index finger by abutting the lower surface of the support arm part, and holding the support arm part, which is closer to the center of gravity in the horizontal direction than the grip part, between the index finger and thumb. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP2018-146395A DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0005] However, although the measurement device in Patent Document 1 is excellent for the person to hold the measurement device while standing, conventional measurement devices, including the measurement device in Patent Document 1, do not fully consider the burden on the body at the moment when the measurement device is taken out from the storage case placed on the floor, etc. That is, for example, a slipped disc is likely to occur when suddenly changing posture or holding something while leaning forward, and in that case, the moment when trying to lift the measurement device can cause back pain.

[0006] The present invention is intended to solve these problems, and has an object to provide a measuring device that is easy to remove from a storage case and reduces the load on the body, such as the cause of lower back pain. [Means for solving the problem]

[0007] The above problem is solved by a measuring device comprising a measuring device main body having a laser light emitting unit that emits laser light for measurement, a base unit that supports the measuring device main body so that it can be rotated horizontally, and a handle protruding from the measuring device main body, wherein the handle protrudes to the rear side along a radial direction from the horizontal center within a range of 40 to 45 degrees to the left and right from the horizontal center when the measuring device main body is in an upright state, and a bulge that bulges furthest forward is formed on the front side of the measuring device main body opposite the handle, and wherein, in the upright state, the handle and a battery that applies voltage to the laser light emitting unit are positioned in different vertical directions with respect to the bulge.

[0008] According to the above invention, in the measuring device that uses laser light for measurement, the handle protrudes from the rear side along a radial direction from the horizontal center of the measuring device body when the measuring device body is in an upright position. In this way, when the measuring device is laid in the storage case with the front side facing down and the lid of the storage case is opened, the handle protrudes upward. Therefore, when the handle is grasped to remove the measuring device from the storage case, it is possible to grasp it without bending forward as deeply as the handle is higher. Therefore, the burden on the lower back when bending forward can be reduced. In other words, the "rear side" referred to here means the surface that can be seen from above when the measuring device is laid down with the front side facing down. Moreover, the handles are positioned within a range of 40 to 45 degrees to the left and right of the center of the measuring device body. This makes it difficult for the wrist to bend when gripping the handles of the measuring device, which are generally smaller than shoulder width, and prevents palmar flexion and dorsiflexion, allowing the gripping force to be exerted effectively. Furthermore, a bulge is formed on the front side of the measuring device body opposite the handle, and when the device is upright, the handle and the battery are arranged upside down relative to the bulge. With this, when the measuring device is laid down on its front side and the handle is lifted to remove it from the case, a downward force is applied to the heavy battery side, and the bulge acts as a fulcrum to rotate the handle side upwards according to the principle of leverage, making it easier to lift, and reducing the force required when the device is bent forward.

[0009] Also preferably, the measuring device body is characterized in that, in the upright state, the front side of the upper surface is formed as a curved inclined surface that slopes downward and is convex outward. In this way, when the measuring device is laid with its front side facing down in the storage case and the handle side (top side) is rotated upward using the bulge as a fulcrum as described above in order to remove it from the storage case, the measuring device body is prevented from getting caught on the storage case, and the measuring device can be smoothly removed from the storage case.

[0010] Also preferably, the measuring device main body has a mirror-tube section in which the laser light emitting section is arranged, and a base section which supports the mirror-tube section so that it can rotate vertically, and the mirror-tube section and the base section have surfaces which are connected to the front side around their boundary with each other, and a continuous pattern is applied from the mirror-tube section to the base section. In this way, since the lens barrel portion and the stand portion have a surface that is continuous with each other on the front side around the boundary between them, it is possible to prevent the main body from getting caught on other members inside the case. With this type of shape, when the device is viewed from a distance, such as during remote operation, the boundary between the lens barrel section and the base section is difficult to see, making it difficult to understand the movement of the lens barrel section. However, in the present invention, a continuous pattern is applied from the lens barrel section to the base section, so that when the lens barrel rotates, the continuous pattern shifts position, making it easier to see the movement.

[0011] In addition, preferably, the batteries are disposed immediately below the left and right handles in the upright position. Therefore, the center of gravity can be moved closer to the handle, making the measuring device easier to hold.

[0012] Also preferably, recesses are formed on the left and right side surfaces of the measuring device body to serve as guides for guiding a gloved hand to the handle, the recesses having a height corresponding to the four fingers other than the thumb when in the upright position, and being positioned from the center of the measuring device body toward the upper side. In this way, the measurer is guided into the recessed portion, which has ample space, and grasps the upper side of the handle from the center (i.e., at a position considerably distant from the battery). Therefore, when removing the lying measuring device from the storage case as described above, the bulge acts as a fulcrum, making it easier to rotate the handle further upwards using the principle of leverage. Effect of the Invention

[0013] As described above, according to the present invention, it is possible to provide a measuring device that is easy to remove from a storage case and reduces the load on the body, such as the cause of lower back pain. [Brief description of the drawings]

[0015] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. The embodiments described below are preferred examples of the present invention, and therefore various technically preferable limitations are attached to them, but the scope of the present invention is not limited to these embodiments unless otherwise specified in the following description to the effect that the present invention is limited to them. Also, the same reference numerals in each drawing have the same configuration.

[0016] 1 to 9 show measuring device 1 according to an embodiment of the present invention, and measuring device 1 will be described first with reference to Fig. 1, which is a schematic front view showing the device in use, and Fig. 2 to 9 as appropriate. Note that the "front" referred to below in this embodiment refers to the surface on which wide-angle camera 19 in Fig. 1 is located, or the surface on which window portion 28 is located when the device is not in operation. The measuring device 1 in the figure is a device that obtains spatial position information of an object by emitting laser light, and is particularly excellent for measuring the three-dimensional shape of buildings, and is also called a laser scanner, etc. Note that the measuring device 10 of the present invention is not limited to a laser scanner, and may be, for example, a laser marking device or rotating laser for determining reference planes and reference lines in civil engineering and construction, or a surveying instrument such as a theodolite or total station for measuring distances and angles.

[0017] The measuring device 1 is generally cylindrical in shape, and in a standing state (i.e., facing the same direction as when it is used on a tripod), the plan view is generally circular except for the handles 70, 71 and the batteries 38, 39. The approximate size is determined so that it can be used on a tripod, and the diameter L as seen from the plan view shown in Fig. 4 is at least smaller than the average shoulder width (about 39.7 cm) of men aged 20 years or older, preferably 40 to 50% of the average shoulder width, and the diameter L in this embodiment is 18.3 cm, which is about 46% of the average shoulder width. The height H1 excluding the antenna 7 in Fig. 1 is preferably 29 to 30 cm, and the height H1 in this embodiment is 29.8 cm.

[0018] As shown in FIG. 1, the measurement device 1 has a leveling table 4, a base unit 3, a measurement device main body 2, and a remote controller 5. [About the leveling stand] The leveling base 4 is fixed onto a tripod 6, and in this embodiment, it is capable of automatic leveling. That is, the leveling base 4 has three leveling screws 4a, and when an automatic leveling switch 21 (see FIG. 2) is turned ON, a known program operates to rotate the leveling screws 4a and automatically adjust the tilt in any direction.

[0019] [About the base] The pedestal 3 is connected onto the leveling table 4 and supports the measuring device body 2 so that it can rotate horizontally. In this embodiment, the pedestal 3 has a motor 31 and a drive gear 32 driven by the motor 31. The drive gear 32 meshes with a horizontal rotation shaft 33 protruding from the bottom surface of the measuring device body 2, allowing the measuring device body 2 to rotate horizontally (left and right direction of the measuring device body 2). A horizontal angle detector 35 (encoder or the like) is provided within the base 3 to detect the rotation angle of the horizontal rotation shaft 33, thereby detecting the relative rotation angle of the measuring device main body 2 in the horizontal direction.

[0020] As shown in FIG. 2, the base unit 3 is also provided with an operation unit 20 and batteries 38 and 39. 2, the operation unit 20 has, in order from the right in Fig. 2, a power switch 23 for the entire apparatus, a laser plummet switch 22, and an automatic leveling switch 21. The laser plummet switch 22 is used during the centering operation, and when it is turned ON, a laser beam is emitted from the bottom surface of the leveling table 4 toward the floor surface or the like, and the position can be adjusted using this as a guide. The automatic leveling switch 21 is a switch for performing the automatic leveling described above. The batteries 38 and 39 are driving power sources that apply a voltage to the laser light emitting unit 52 described later and also supply power to each component, and are detachable in this embodiment, but may be of a type that can be charged while fixed to the base unit 3. The batteries 38 and 39 will be described later.

[0021] [About the measuring device itself] As shown in FIG. 1, the measurement device main body 2 has a lens barrel portion 50 incorporating a laser light emitting portion 52, and a base portion 10 which is generally U-shaped and supports the lens barrel portion 50 inside so that the lens barrel portion 50 can rotate freely. The base unit 10 has therein a drive gear 12 and a motor 14 that drives the drive gear 12. The drive gear 12 meshes with a vertical rotation shaft 16 that connects the lens barrel unit 50 and the base unit 10, thereby allowing the lens barrel unit 50 to rotate freely in the vertical direction (up and down direction of the lens barrel unit 50).

[0022] A vertical angle detector 18 (encoder or the like) is provided within the base unit 10 to detect the rotation angle of the vertical rotation shaft 16, thereby detecting the relative rotation angle of the lens barrel unit 50 in the vertical direction. In this way, the rotation shafts 16, 33, the drive gears 12, 32, and the motors 14, 31 work together to orient the lens barrel 50 in the desired horizontal and vertical directions. In addition, the rotation angle detectors 18, 35 can detect the rotation angles of the lens barrel 50 in the horizontal and vertical directions.

[0023] A wide-angle camera 19 is provided on the support unit 10. The wide-angle camera 19 is mainly used for observation, and an image captured by the wide-angle camera 19 is displayed on the display unit 5a of the remote controller 5. This allows the measurer to search for an object to be measured on the display unit 5a and select the object to be measured with the remote controller 5. The wide-angle camera 19 has a wide angle of view of, for example, 30°. A pair of handles 70, 71 protrude from the outer surface of the support part 3, which is a part of the measuring device main body 2. The handles 70, 71 are means for lifting and moving the measuring device 1, and are made of a plastic material such as ABS resin that has high rigidity and water resistance. The handles 70, 71 may be fixed or detachable. The handles 70, 71 will be described later.

[0024] The lens barrel 50 has therein a laser beam emitting section 52 and a laser beam receiving section 54 which constitute a distance measuring section. The laser light emitting unit 52 has a light emitting element, a light projecting lens, and a deflection prism (not shown). The light emitting element can be, for example, a laser diode that emits laser light, and the emitted laser light passes through the internal light projecting lens and deflection prism, and then through the transparent window 28 on the optical axis of the laser light, and is irradiated onto the measurement object. The laser light receiving unit 54 has a light receiving element, a reflective deflection prism, and an imaging lens (not shown). The light receiving element is, for example, a photodiode, and the light reflected by the object to be measured is collected on the light receiving element via the reflective deflection prism and the imaging lens. When the light receiving element receives the light, it converts it into a signal and transmits it to the calculation processing unit 56, which measures the time it takes for the laser light to return and performs distance measurement using a known calculation.

[0025] Such a lens barrel unit 50 also has a narrow-angle camera 58 with a narrower angle of view than the wide-angle camera 19 described above. The narrow-angle camera 58 captures the measurement object selected by the wide-angle camera 19, and the image acquired by the narrow-angle camera 58 is displayed on the display unit 5a. This narrow-angle image coincides with the measurement range of the measuring device 1, so the measurer can easily specify the measurement range using the display unit 5a and can point the lens barrel unit 50 toward the desired measurement object. This narrow-angle camera 49 has a narrow angle of view of, for example, 5°. When the laser light is emitted horizontally, the wide-angle camera 19, narrow-angle camera 58, and window portion 28 of this embodiment are aligned in a line along the vertical direction of the device.

[0026] The optical axis of narrow-angle camera 58 and the optical axis of the laser emitted from laser light emitting unit 52 are parallel, and the center of the image captured by narrow-angle camera 58 is aligned with the laser optical axis by known calculations. A control unit (not shown) electrically connected to the arithmetic processing unit 56 specifies the emission direction angle of the laser light (distance measurement light) based on the detection results of the vertical angle detector 18 and the horizontal angle detector 35, and calculates three-dimensional data (X, Y, Z) of the measurement object using a known program based on the distance measurement results. Then, the three-dimensional data of the measurement point is associated with the narrow-angle image, and the narrow-angle image acquired by the narrow-angle camera 58 can be displayed on the display unit 5a of the remote controller 5 as an image with three-dimensional data.

[0027] [About the remote controller] The remote controller 5 communicates with the measuring device main body 2 via the antenna 7 by means of wireless LAN or the like, and can remotely operate the measuring device 1, using a dedicated terminal or smartphone that stores a known program. Images captured by the wide-angle camera 19 and narrow-angle camera 58 described above are displayed on the display unit 5a of the remote controller 5 of this embodiment, and since the display unit 5a has a touch sensor function, the user can touch the screen while checking the images to move the lens barrel unit 50 and the support unit 10, and select or capture the object to be measured.

[0028] The measuring device 1, which is the above-mentioned laser product, is a precision instrument, and is stored in a storage case 60 shown in FIG. 10, for example, when not in use. The storage case 60 has a case body 61 and a lid body 62 that is shorter than the case body 61 (see also FIG. 11). A protective member 63 such as a cushioning material having a recess 40 formed therein corresponding to the outer shape of the measuring device 1 is provided on the inside of the case body 61 and the lid body 62. In the figure, the recess 40a of the case body 61 corresponds to the front half of the measuring device 1, and the recess 40b of the lid body 62 corresponds to the rear half of the measuring device 1. As a result, in the closed state, the inner surface of the recess 40a of the case body 61 and the inner surface of the recess 40b of the lid body 62 are in close contact with the measuring device 1, protecting the measuring device 1. Normally, as shown in the figure, the front side (the face in FIG. 2) on which window portion 28 and lenses 19, 58, which would be fatally defective if scratched, are arranged faces downward, and the front side of measuring device 1 on which window portion 28 and lenses 19, 58 are located is protected by case body 61, which has a thicker protective member 63 than lid 62. For this reason, as shown in the figure, when lid 62 is opened to remove measuring device 1, the rear side opposite to the front side is exposed.

[0029] The measurement device 1 of this embodiment is configured as described above, and further has the following features. [About the handle] Since the handles 70, 71 have the same configuration except for their arrangement, only the configuration of the handle 71 will be described here unless otherwise specified. As shown in Figures 8 and 9, handle 71 is a vertical handle that is approximately U-shaped with two bent portions 71a and 71b, and has a grip portion 72 that is held by the fingers, and upper and lower support arm portions 73 and 74 that support grip portion 72 on the measuring device main body 2. Grip portion 72 has a projection D1 that does not extend beyond the center of the back surface. That is, in order to prevent grip portion 72 from being separated from the center of gravity of measuring device 1 and making it difficult to hold, grip portion 72 is located on the front side of tangent line TA (see FIG. 5) to the center of the back surface of measuring device 1, which is approximately circular in plan view. Projection D1 in the figure is 5.3 cm.

[0030] An insertion space S into which gloved fingers can be inserted is provided between grip portion 72 and the housing of measurement device main body 2. Grip portion 72 also has a width dimension W1 corresponding to the dimension between the metacarpal phalangeal joint (MP) at the base of the fingers excluding the thumb and the proximal interphalangeal joint (PIP), the second joint from the tip of the finger (see FIG. 12 for the joint positions), allowing the finger joints to be bent and grip portion 72 to be grasped through gloves.

[0031] 2 to 4, when the measuring device main body 2 is upright, the handles 70, 71 protrude from the horizontal center OP in a radial direction toward the rear side opposite the wide-angle camera 19, so as to be spaced apart from each other. As a result, when the measuring device 1 is laid down in the storage case 60 with the front side facing down to protect the window 28 and the lenses 19, 58, as shown in FIG. 10, the handles 70, 71 are located at the top. Therefore, when bending forward to remove the measuring device 1 from the storage case 60 (see FIG. 11), the handles 70, 71 can be grasped with a shallow forward bending since the handles 70, 71 are located at the top, and the burden on the lower back when bending forward can be reduced.

[0032] Furthermore, when the entire cylindrical measuring device 1 is upright, the handles 70, 71 are disposed within a range of 40 to 45 degrees to the left and right of the horizontal center OP of the measuring device main body 2, as shown in Fig. 4. Specifically, in the plan view shown in Fig. 4, with the horizontal center OP and a center line CL passing through a portion 29 of the back surface directly opposite the window portion 28 (i.e., the center of the back surface) as a reference, one handle 70 is disposed at a central angle θ2 of 40 to 45 degrees, and the other handle 71 is also disposed at a central angle θ1 of 40 to 45 degrees. As a result, as shown in Fig. 11, when a Japanese male aged 20 or over, approximately 172 cm tall, leans forward slightly with his waist slightly lowered and holds the handles 70, 71 located inside the shoulder width with his upper arms lowered approximately vertically, he is able to hold the handles without bending his wrists. In other words, when holding the handles, the forearm and fist are straight as shown in Fig. 12(b) without the palmar flexion of Fig. 12(a) or the dorsiflexion of Fig. 12(c), and the gripping force is most effectively exerted. Of course, depending on the individual characteristics of the person being measured, such as his height, posture, and habits, the state shown in Fig. 12(b) is not necessarily achieved, but the posture, such as the tightness of the armpits and the angle of the arms, can be easily adjusted, and the handles 70, 71 play the role of a guide to the state shown in Fig. 12(b). In the figure, the angle θ1 on the right side and the angle θ2 on the left side are the same and are each set at 45 degrees.

[0033] Furthermore, the surface exposed to the outside of handle 71, i.e., the surface opposite insertion space S into which the finger is inserted, is provided with the brightest marking on measuring device body 2. Therefore, when opening lid 62 as shown in Fig. 10 to remove measuring device 1 from storage case 60 in a relatively dark place such as a dimly lit room, handle 71 becomes easy to find, and the deeply bent posture can be quickly corrected.

[0034] [About the bulging part] 6 and 7, a bulging portion 80 that bulges out most forward is formed on the front side of the measuring device body 2 opposite the handles 70, 71. In the case of this embodiment, when the measuring device 1 is in an upright position, the front side of the measuring device body 2 is recessed so as to be chamfered from the center to the upper side, and the front side of the base part 3 is recessed from the center to the lower side, thereby forming the bulging portion 80. When the measuring device 1 is upright, the handles 70, 71 and the batteries 38, 39 are located at different positions in the up-down direction with the bulging portion 80 as the reference (boundary). In the figure, the handles 70, 71 are disposed on the upper surface side (flat surface side in FIG. 4) of the bulging portion 80, and the batteries 38, 39 are disposed on the lower surface side (bottom surface side in FIG. 5) of the bulging portion 80. In this way, when removing the measuring device 1 from the storage case while it is lying on its front side as shown in FIG. 13 (storage case not shown), lifting the handle 71 will apply a downward force to the heavy battery 39, and the bulge 80 will act as a fulcrum and cause the handle 71 to rotate upward LF according to the principle of leverage, making it easier to lift and reducing the amount of force required when bending over.

[0035] Furthermore, in this embodiment, the measuring device 1 has the following additional features to make it easier to lift. [Additional feature 1] First, in the upright state shown in Fig. 3, the left and right batteries 38, 39 are disposed directly below the left and right handles 70, 71, respectively. In Fig. 3, the right battery 38 is disposed below the right handle 70, and the left battery 39 is disposed below the left handle 71. This makes it possible to move the center of gravity as close as possible to the handles 70, 71 side, making it easier to hold the heavy measuring device 1. It is preferable that the battery 38 and the battery 39 have the same weight.

[0036] [Additional feature 2] Next, as shown in FIG. 3 and FIG. 13, a recess 25 is formed on each of the left and right side surfaces of the measuring device main body 2 (the left and right side surfaces of the support part 10 in this embodiment). The recess 25 is a guide for easily guiding the fingers of a gloved hand into the space S between the handles 70, 71 and the left and right side surfaces of the measuring device main body 2. Specifically, when the measuring device 1 is in an upright state, the height H2 (the width in the lying state in FIG. 13, see also FIG. 6) corresponding to the four fingers other than the thumb wearing the glove corresponds to the width of the four fingers other than the thumb wearing the glove. The recess 25 is disposed from the center of the measuring device main body 2 to the upper side (the flat side in FIG. 4) (i.e., toward the upper side of the side surface corresponding to the space S). Then, as shown in FIG. 13, the measurer is guided by the recess 25 with ample space to grasp the handles 70, 71 at the positions farthest from the batteries 38, 39, making it easier to rotate them in the LF direction by the principle of leverage. Incidentally, the same effect as in this embodiment can be obtained even if the handles 70, 71 are provided only on the upper side (the flat surface side in FIG. 4) from the beginning, but in that case, when the measuring device 1 is placed on a tall tripod and fixed, the handles will be only on the upper side, making it difficult to operate. For this reason, in the upright state of FIG. 3, it is preferable to provide the handles 70, 71 widely from the top to the bottom of the measuring device main body 2, and to set the recessed portion 25, which serves as a guide for guiding the fingers, to a height H2 based on the top of the space S, which is sufficient to accommodate four gloved fingers.

[0037] [Additional feature 3] Next, as shown in Fig. 6 to Fig. 8, the front side area 2A of the upper surface (surface seen from the plane of Fig. 4) of the measuring device main body 2 in the standing state is a curved inclined surface that is inclined downward and convex outward. Specifically, the front side areas 50A, 10A of the upper surfaces of both the lens barrel part 50 and the stand part 10 (see Fig. 8) are curved inclined surfaces that are similarly curved as described above. In this way, when the measuring device 1, which is laid in the storage case with the front side where the window part 28 is located facing down as shown in Fig. 13, is rotated in the LF direction with the bulge part 80 as a fulcrum to remove the measuring device 1 from the storage case, the measuring device main body 2 is prevented as much as possible from getting caught on the protective member 63 of the storage case, and the measuring device 1 can be smoothly removed from the storage case. It should be noted that only narrow-angle camera 58 does not have a curved inclined surface, but this is because the optical axis of narrow-angle camera 58 and the laser optical axis emitted from laser light emission unit 52 need to be parallel, and the present invention also includes cases where there are no curved inclined surfaces in some areas.

[0038] [Additional feature 4] 2 and 8, the lens barrel part 50 and the base part 10 have surfaces 26, 27 that are connected to each other on the front side around their boundary. This "connected surface" refers to the state where the lens barrel part 50 and the base part 10 are not in close contact with each other and there is a space at the boundary, but the surfaces 26, 27 are close to each other as if they were the same surface. The reason why the surfaces 26, 27 are connected in this way is to prevent the lens barrel part 50 from getting caught when it is removed from the storage case as much as possible. The continuous surface is shaped like a flat cut-away portion of the front side of the generally cylindrical measurement device main body 2. This makes it easier for the measurer to grasp the front side compared to when the entire body is generally cylindrical.

[0039] Here, as described above, if the lens barrel part 50 and the base part 10 are connected to the front side at the surfaces 26, 27, it becomes difficult to visually recognize the boundary between the lens barrel part 50 and the base part 10 when viewing the device from a distance, such as during remote operation. Moreover, in the first place, in this embodiment, the lens barrel part 50 is designed not to protrude from the base part 10 as much as possible. Then, with such a configuration, it becomes difficult to understand the movement of the lens barrel part 50. Therefore, the following additional features are provided to make the movement of the lens barrel part 50 easier to understand.

[0040] [Additional feature 5] First, as shown in Figures 8 and 9, the measuring device 1 has indicators 41, 43 consisting of LEDs or the like that light up when the lens barrel 50 rotates. The indicators 41, 43 are disposed on the outer surface of the support unit 10, below the lens barrel 50. The indicators 41, 43 in the figures are disposed on the front and back and light up in the same color, but the indicators may light up in different colors on the front and back, or light up in different ways such as by flashing, so that the front and back can be distinguished from each other.

[0041] [Additional feature 6] Next, in this embodiment, a continuous pattern is applied from the lens barrel portion 50 to the stand portion 10 so that the pattern shifts as the lens barrel portion 50 rotates. FIG. 14 is a diagram for explaining this continuous pattern, where FIG. 14(A) is a diagram showing the state when not being driven, and FIG. 14(B) is a diagram showing the lens barrel portion 50 rotated downward. As shown in FIG. 14(A), there is a space between the lens-barrel portion 50 and the base portion 10, but when not in operation, the pattern D2 on the base portion 10 side of the lens-barrel portion 50 and the pattern D1 on the lens-barrel portion 50 side of the base portion 10 are close to each other, creating a continuous pattern DS. The continuous pattern DS in the figure is a line or band applied from the lens barrel part 50 to the base part 10, and is made into a ring shape so as to surround the window part 28 and the cameras 19, 58. Therefore, when the lens barrel part 50 rotates vertically, as shown in Fig. 14(B), the line / band D2 of the lens barrel part 50 and the line / band D1 of the base part 10 separate from each other, breaking the continuous pattern, and this allows the movement of the lens barrel part 50 to be seen. The continuous pattern DS has a uniform color, and is made yellowish so that it stands out even if the width of the line / band is narrow.

[0042] [Additional feature 7] Next, the inner area GN (the area with parallel diagonal lines in Figure 14) surrounded by the above-mentioned circular continuous pattern DS is a different color from the continuous pattern DS, and is a uniform color except for the upper and lower areas 50A, 50B of the lens barrel portion 50 (i.e., the front side area on the upper surface and the front side area on the lower surface). The color of this inner region GN is preferably far from the color of the continuous pattern DS, and since the continuous pattern DS in this embodiment is yellowish, the inner region GN is blackish except for the upper and lower regions 50A, 50B of the lens barrel portion 50. The upper and lower regions 50A, 50B of the lens barrel portion 50 are different in color from the continuous pattern DS and the inner region GN, and preferably have a hue intermediate between the color of the continuous pattern DS and the color of the inner region GN, and are silver in the illustrated example. Because the inner area GN surrounded by the continuous pattern DS is constructed as described above, when the lens-barrel section 50 rotates downward as shown in Figure 14 (B), the black colors of the inner area GN on the support section 10 side do not move, while the silver color of the upper area 50A of the lens-barrel section 50 increases from the top, and conversely, when the lens-barrel section 50 rotates upward, the silver color of the lower area 50B of the lens-barrel section 50 increases from the bottom, making the movement in the vertical direction easier to see.

[0043] The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the claims. For example, in Figures 1 to 9, bulge 80 is located in front where wide-angle camera 19 is located, and handles 70, 71 are located on the back side opposite wide-angle camera 19, but the positional relationship between bulge 80 and handles 70, 71 is relative to the horizontal center OP, and wide-angle camera 19 is not necessarily the basis for determining the front and back.

[0044] 15 to 22, the antenna 7 may be built-in or may not be present. The batteries 38 and 39 may be integrated into one. Although the bulging portion 80 in FIG. 7 is composed of the bulging portion 80A on the measuring device main body 2 side and the bulging portion 80B on the base 3 side, the present invention is not limited to this. Only the bulging portion 80A on the measuring device main body 2 side may be the bulging portion 80, and the bulging portion may not be formed on the base 3.

[0045] Alternatively, in the above embodiment, as shown in FIG. 6, the side above the bulge 80 of the measuring device body 2 is recessed to form a substantially vertical flat surface, but as in a measuring device 90 shown in FIGS. 23 and 24 which is a modified example, the side above the bulge 80 of the measuring device body 2 may be formed as an inclined surface in which the outer shape of the measuring device body 2 narrows toward the upper surface. 1 to 9, the entire barrel 50 rotates vertically and the window 28 also rotates, but in the measuring device 90 of FIGS. 23 and 24, the entire surface exposed to the outside of the barrel 94 is a transparent window, and the laser light emitting part inside rotates vertically to emit laser light. Also, the camera 92 of the measuring device 90 has two functions: a wide-angle camera and a narrow-angle camera. The above-mentioned configuration is also included in the present invention.
