Description

Technical Field

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

[0002] Conventionally, there are known measuring devices using lasers, and the measuring devices are used in various situations, such as obtaining spatial position information of an object by receiving reflected light of emitted laser light or determining a reference plane or reference line of civil engineering by irradiating a object with laser light.

[0003] Since the horizontal and vertical levels of the measuring device are important, a tripod is often used, and the surveyor holds a handle installed on the measuring device and places it on the tripod, fixes the tripod and the measuring device, and uses it.

[0004] Thus, since a heavy measuring device needs to be fixed on a high tripod, a measuring device that is easy to hold is proposed. For example, the handle of the measuring device of Patent Document 1 is composed of a grip portion that is grasped by fingers and a support arm portion that mounts and supports the grip portion on a housing, and a curved portion that matches the shape of the thumb is formed on the upper surface of the support arm portion. In this way, the measuring instrument can be easily held by hand by grasping the handle with four fingers other than the thumb, and by making the index finger abut against the lower surface of the support arm portion to support the support arm portion from below, and by holding the support arm portion that is closer to the center of gravity than the grip portion with the index finger and thumb in the horizontal direction.

[0007] Patent Document 1: Japanese Patent Application Publication No. 2018-146395 Summary of the invention

[0008] Problem that the invention aims to solve

[0009] However, although it is excellent that the measuring person holds the measuring device while standing in the patent document 1, the conventional measuring devices are not limited to the measuring device of the patent document 1, and the burden on the body at the moment of taking out the measuring device from the storage box placed on the floor, etc. That is, for example, the waist is easily sprained when the posture is suddenly changed or when leaning forward to pick up something, so the moment of trying to lift the measuring device may become a cause of back pain.

[0010] The present invention is to solve such a problem, and an object of the present invention is to provide a measuring device that can be easily taken out of a storage box and that can reduce the load on the body caused by, for example, back pain.

[0011] Means used to solve problems

[0012] The above-mentioned problem can be solved by the following measuring device, which comprises a measuring device body, a base part and a handle, wherein the measuring device body comprises a laser emitting part for emitting a laser for measurement, the base part supports the measuring device body so as to be rotatable in the horizontal direction, and the handle protrudes from the measuring device body, wherein the handle protrudes toward the back side along the radial direction from the horizontal center in the range of 40 to 45 degrees to the left and right from the horizontal center of the measuring device body in the upright state, and a bulging part bulging most forward is formed on the front side of the measuring device body on the opposite side to the handle, and in the upright state, the handle and a battery for applying voltage to the laser emitting part have different positions in the up-down direction with reference to the bulging part.

[0013] According to the above invention, in a measuring device that uses a laser for measurement, when the measuring device body is erected, the handle protrudes toward the back side along the radial direction from the horizontal center of the measuring device body. In this way, when the lid of the storage box is opened in a state where the front side is placed in the storage box with the front side facing down, the handle is on the upper side. Therefore, when the handle is grasped to take out the measuring device from the storage box, the handle can be grasped even if the handle is not bent forward deeply to the extent that the handle is located above. Therefore, the burden on the waist when bending forward can be reduced. That is, the "back side" mentioned here refers to the side that can be visually confirmed when observed from above in a state where the front side is placed with the front side facing down.

[0014] Furthermore, the handle is arranged at a range of 40 to 45 degrees to the left and right from the center of the measuring device body. This makes it difficult for the wrist to bend when holding the handle of the measuring device that is generally smaller than the shoulder width, which becomes a factor to prevent palmar flexion and dorsiflexion, and can effectively exert the grip strength.

[0015] Furthermore, a bulging portion that bulges forward most is formed on the front side of the measuring device body on the opposite side from the handle, and in the upright state, the handle and the battery are arranged opposite to each other up and down with the bulging portion as a reference. In this way, when the measuring device is taken out of the box in a lying state with the front side facing downward, when the handle is lifted, the downward force of the heavier battery side acts, and the bulging portion becomes a fulcrum, and according to the principle of leverage, it is easy to turn the handle side upward and lift it, and the force in the forward bending state can be suppressed.

[0016] In addition, it is preferred that, in the standing state, the front side of the upper surface of the measurement device body is formed as a curved inclined surface that is inclined downward and convex outward.

[0017] This prevents the measuring device from being placed with its front side facing down in a storage box in order to be taken out from the storage box. When the handle side (upper surface side) is rotated upward with the bulge as a fulcrum as described above, the measuring device body is stuck in the storage box, and the measuring device can be smoothly taken out of the storage box.

[0018] Another feature is that, preferably, the measuring device body has a barrel portion and a bracket portion, the barrel portion is provided with the laser emitting portion, the bracket portion supports the barrel portion so as to be rotatable in a vertical direction, the barrel portion and the bracket portion have surfaces connected to each other on the front side around the boundary, and a continuous pattern is formed from the barrel portion to the bracket portion.

[0019] In this way, the lens barrel portion and the bracket portion have surfaces connected to each other on the front side around the boundary, so it is possible to prevent the main body from being caught by other components in the box.

[0020] In this regard, if it is such a shape, it is difficult to visually confirm the boundary between the lens barrel portion and the bracket portion when observing the device from a distance through remote operation, etc., and it is difficult to know the movement of the lens barrel portion. However, in the present invention, since a continuous pattern is formed from the lens barrel portion to the bracket portion, when the lens barrel rotates, the continuous pattern is misaligned, making it easy to know that movement has occurred.

[0021] Another feature is that, preferably, in the upright state, the battery is arranged directly below each of the left and right handles.

[0022] Therefore, the center of gravity can be brought closer to the handle, making it easier to hold the measuring device.

[0023] Another feature is that, preferably, recessed portions are formed on the left and right side surfaces of the measuring device body, the recessed portions are guide portions for guiding the gloved hand to the handle, and in the upright state, the recessed portions have a height corresponding to four fingers other than the thumb wearing the gloves, and are arranged from the central portion of the measuring device body to the upper side.

[0024] In this way, the measurer is guided to the recessed portion with ample space and holds the upper side from the center of the handle (i.e., a position quite far from the battery). Therefore, as described above, when taking out the horizontal measuring device from the storage box, the bulging portion becomes a fulcrum, making it easier to turn the handle side upward using the lever principle.

[0025] Effects of the Invention

[0026] As described above, according to the present invention, it is possible to provide a measuring device that is easy to take out from a storage box and that reduces the load on the body caused by, for example, back pain. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0052] In addition, the embodiments described below are preferred specific examples of the present invention, and therefore various technically preferred limitations are given, but as long as the meaning of the present invention is not particularly limited in the following description, the scope of the present invention is not limited to these modes. In addition, the same reference numerals marked in each of the accompanying drawings have the same structure.

[0053] Figures 1 to 9 The measuring device 1 according to the embodiment of the present invention is shown in a schematic front view in a usage state. Figure 1 Centered on Figure 2 to Figure 9 The measuring device 1 is described below. In the present embodiment, the "front side" is Figure 1 The surface where the wide-angle camera 19 is located, or the surface where the window portion 28 is located in the non-driven state.

[0054] 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 in measuring the three-dimensional shape of a building, and is also called a laser scanner, etc. In addition, 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 a rotating laser for determining a reference plane or reference line in civil engineering or construction, or a measuring instrument such as a theodolite or a total station for measuring distance or angle.

[0055] The measuring device 1 is generally cylindrical in shape. When the measuring device 1 is in an upright position (i.e., in the same direction as when it is fixed on a tripod for use), it is generally circular in shape when viewed from above, except for the handles 70, 71 and the batteries 38, 39. In order to be fixed on a tripod for use, the measuring device 1 has a predetermined size. Figure 4 The diameter L observed on the upper surface shown is smaller than the average shoulder width (about 39.7 cm) of men over 20 years old, preferably 40-50% of the average shoulder width. The diameter L of this embodiment is about 46% of the average shoulder width, that is, 18.3 cm. Figure 1 The height H1 excluding the antenna 7 is preferably 29 to 30 cm, and the height H1 in the present embodiment is 29.8 cm.

[0056] like Figure 1 As shown, the measuring device 1 comprises a calibration platform 4, a base 3, a measuring device body 2, and a remote controller 5.

[0057] 〔About the school platform〕

[0058] The leveling platform 4 is fixed on the tripod 6 and can be automatically leveled in the present embodiment. That is, the leveling platform 4 has three leveling screws 4a, which are adjusted by the automatic leveling switch 21 (see Figure 2 ) is turned on, a known program runs, so that the leveling screw 4a rotates, automatically adjusts and tilts in any direction.

[0059] [About the base]

[0060] The base 3 is connected to the calibration platform 4, and supports the measuring device body 2 so that it can rotate in the horizontal direction. In the case of this embodiment, the base 3 has a motor 31 and a driving gear 32 driven by the motor 31. In addition, the driving gear 32 is engaged with a horizontal rotation shaft 33 protruding from the lower surface of the measuring device body 2, thereby allowing the measuring device body 2 to rotate freely in the horizontal direction (the left-right direction of the measuring device body 2).

[0061] Furthermore, a horizontal angle detector 35 (encoder or the like) for detecting the rotation angle of the horizontal rotation shaft 33 is provided in the base portion 3 , thereby detecting the relative rotation angle of the measuring device body 2 in the horizontal direction.

[0062] like Figure 2 As shown, the base portion 3 is also provided with an operating portion 20 and batteries 38 , 39 .

[0063] The operation unit 20 is Figure 2 The power switch 23, laser centripetal switch 22, and automatic leveling switch 21 of the whole device are arranged in order from the right side. The laser centripetal switch 22 is used during the centripetal operation. If it is turned on, the laser is irradiated from the bottom surface of the leveling platform 4 to the ground, etc., and the position can be adjusted based on this. The automatic leveling switch 21 is a switch for performing the above-mentioned automatic leveling.

[0064] The batteries 38 and 39 are driving power sources for applying voltage to the laser emitting unit 52 described later and supplying power to various components. In this embodiment, the batteries 38 and 39 are detachable, but may be fixed to the base 3 and charged directly. The batteries 38 and 39 will be described later.

[0065] [About the measuring device]

[0066] like Figure 1 As shown, the measuring device body 2 includes a lens barrel 50 in which a laser emitting unit 52 is built, and a bracket 10 which is generally U-shaped and supports the lens barrel 50 rotatably inside the bracket 10 .

[0067] The bracket 10 has a driving gear 12 and a motor 14 driving the driving gear 12. The driving gear 12 meshes with a vertical rotation shaft 16 connecting the lens barrel 50 and the bracket 10, whereby the lens barrel 50 is freely rotatable in the vertical direction (up and down direction of the lens barrel 50).

[0068] Furthermore, a vertical angle detector 18 (an encoder or the like) for detecting the rotation angle of the vertical rotation shaft 16 is provided in the bracket portion 10 , thereby detecting the relative rotation angle of the lens barrel portion 50 in the vertical direction.

[0069] Thus, the rotating shafts 16, 33, the driving gears 12, 32, and the motors 14, 31 cooperate to direct the lens barrel 50 to the desired horizontal and vertical directions. In addition, the rotation angle detectors 18, 35 can detect the rotation angle of the lens barrel 50 in the horizontal and vertical directions.

[0070] In addition, a wide-angle camera 19 is provided on the bracket 10. The wide-angle camera 19 is mainly used for observation, and the image obtained by the wide-angle camera 19 is displayed on the display unit 5a of the remote controller 5. Thus, the measurer can find the measurement object from the display unit 5a and select the measurement object through the remote controller 5. The wide-angle camera 19 has a wide field angle of, for example, 30°.

[0071] In addition, a pair of handles 70 and 71 protrude from the outer surface of the bracket portion 3 which is a part of the measuring device body 2. The handles 70 and 71 are a mechanism for lifting or moving the measuring device 1, and are made of a plastic material such as ABS (AcrylonitrileButadieneStyrene: acrylonitrile-styrene-butadiene copolymer) resin with high rigidity and water resistance. The handles 70 and 71 can be fixed or detachable. The handles 70 and 71 will be described later.

[0072] The lens barrel 50 includes a laser emitting unit 52 and a laser receiving unit 54 which constitute a distance measuring unit.

[0073] The laser emitting unit 52 has a light emitting element and a projection lens or a deflection prism (not shown). The light emitting element can use a laser diode that emits laser light, and the emitted laser light passes through the projection lens or deflection prism located inside and the transparent window 28 located on the optical axis of the laser light to irradiate the measurement object.

[0074] The laser light receiving unit 54 has a light receiving element and a reflective deflection prism or an imaging lens (not shown). The light receiving element is, for example, a photodiode, and the reflected light reflected by the measured object is focused on the light receiving element via the reflective deflection prism or the imaging lens. When the light receiving element receives light, it sends it as a signal to the calculation processing unit 56, and the calculation processing unit 56 measures the time until the laser returns and performs distance measurement through known calculations.

[0075] Such a lens barrel 50 further includes a narrow-angle camera 58 having a narrower field of view than the wide-angle camera 19. The narrow-angle camera 58 captures the measurement object selected by the wide-angle camera 19, and the image obtained by the narrow-angle camera 58 is displayed on the display unit 5a. Since the narrow-angle image coincides with the measurement range of the measurement device 1, the measurer can easily determine the measurement range through the display unit 5a and can direct the lens barrel 50 toward the desired measurement object. The narrow-angle camera 49 has a narrow field of view of, for example, 5°.

[0076] Furthermore, when emitting laser light horizontally, wide-angle camera 19 , narrow-angle camera 58 , and window 28 of the present embodiment are arranged in a row in the vertical direction of the device.

[0077] The optical axis of the narrow-angle camera 58 is parallel to the optical axis of the laser light emitted from the laser light emitting unit 52 , and the center of the image of the narrow-angle camera 58 is made to coincide with the optical axis of the laser light by known calculations.

[0078] Furthermore, a control unit (not shown) electrically connected to the calculation processing unit 56 determines the emission direction angle of the laser (distance measuring light) based on the detection results of the vertical angle detector 18 and the horizontal angle detector 35, and calculates the three-dimensional data (X, Y, Z) of the measurement object based on the above-mentioned distance measurement results through a known program. Then, the three-dimensional data of the measurement point is associated with the narrow-angle image, and the narrow-angle image obtained 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.

[0079] [About the remote control]

[0080] 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 the measuring device 1 can be remotely operated using a dedicated terminal or a smart phone storing a known program. The display unit 5a of the remote controller 5 of this embodiment displays the image captured by the wide-angle camera 19 or the narrow-angle camera 58, but since the display unit 5a has a touch sensor function, the lens barrel 50 or the bracket 10 can be moved while the image is checked, and the measuring object can be selected or captured by touching the screen.

[0081] The measuring device 1 of the above laser product is a precision device and is stored in a storage container when not in use. Fig.10 The storage box 60 shown in FIG. 60 includes a box body 61 and a cover body 62 (also see FIG. 61 ) whose height is lower than that of the box body 61. Fig.11 ). A protective member 63 such as a cushioning material having a recess 40 corresponding to the outer shape of the measuring device 1 is provided inside the box body 61 and the cover body 62. In the case of the figure, the recess 40a of the box body 61 is a shape corresponding to half of the front side of the measuring device 1, and the recess 40b of the cover body 62 is a shape corresponding to half of the back side of the measuring device 1. Thus, in the closed state, the inner surface of the recess 40a of the box body 61 and the inner surface of the recess 40b of the cover body 62 are in close contact with the measuring device 1, thereby protecting the measuring device 1.

[0082] In addition, usually, as shown in the figure, the window portion 28 where the scratch is a fatal defect and the front surface ( Figure 2 The front side where the window 28 and the lenses 19 and 58 of the measuring device 1 are located is protected by the box body 61, which is thicker than the cover 62, and the protective member 63. Therefore, as shown in the figure, when the cover 62 is opened to take out the measuring device 1, the back side opposite to the front side is exposed.

[0083] The measuring device 1 of the present embodiment is configured as described above, and further has the following features.

[0084] 〔About the handle〕

[0085] Since the handles 70 and 71 have the same structure except for the configuration, only the structure of the handle 71 will be described here unless otherwise specified.

[0086] like Figure 8 , Fig. 9 As shown, the handle 71 is a substantially U-shaped vertical handle having two bent portions 71 a and 71 b as a whole, and includes a grip portion 72 to be gripped with fingers and upper and lower support arms 73 and 74 that support the grip portion 72 on the measurement device body 2 .

[0087] In addition, the handle portion 72 has a protruding width D1 that does not protrude outward from the center of the back surface. That is, in the measuring device 1 that is substantially circular in plan view, the handle portion 72 is located at a position that is larger than the tangent line TA (see FIG. 1 ) at the center of the back surface. Figure 5 ) is located near the front side so that the grip portion 72 is away from the center of gravity of the measuring device 1 and does not become difficult to hold. The protruding width D1 in the figure is 5.3 cm.

[0088] An insertion space S is provided between the grip portion 72 and the housing of the measuring device body 2 so that a gloved finger can be inserted. The grip portion 72 has a width dimension W1 corresponding to the dimension between the joint MP (metacarpal phalangeal joint) at the base of the fingers other than the thumb and the second joint PIP (proximal interphalangeal joint) from the fingertip (for joint positions, refer to Fig.12 ), thereby making it possible to bend the joints of the above-mentioned fingers and grasp the handle portion 72 through the gloves.

[0089] like Figure 2 to Figure 4 As shown in FIG. 1 , when the measuring device body 2 is erected, the handles 70 and 71 protrude in a manner separated from each other along the radial direction from the horizontal center OP of the measuring device body 2 toward the back side opposite to the wide-angle camera 19. Fig.10 As shown in FIG. 1 , in a state where the front side is placed downward in the storage box 60 to protect the window portion 28 and the lenses 19 and 58, the handles 70 and 71 are located at the top. Therefore, when the measuring device 1 is bent forward to be taken out of the storage box 60 (see FIG. 1 ), the measuring device 1 is placed in the storage box 60. Fig.11 ), the handles 70, 71 can be held by bending forward slightly to a degree corresponding to the amount by which the handles 70, 71 are located above, which can reduce the burden on the waist when bending forward.

[0090] Furthermore, when the measuring device 1, which is cylindrical in shape as a whole, is erected, Figure 4 As shown in FIG. 1 , the handles 70 and 71 are arranged in a range of 40 to 45 degrees to the left and right from the horizontal center OP of the measuring device body 2. Figure 4 In the top view shown, with the horizontal center OP and the center line CL passing through the back portion 29 completely opposite to the window portion 28 (i.e., the center of the back) as a reference, the handle 70 on one side is configured at a center angle θ2 of 40 to 45 degrees, and the handle 71 on the other side is also configured at a center angle θ1 of 40 to 45 degrees.

[0091] Therefore, if Fig.11 As shown in the figure, a Japanese male aged 20 or above with an average height of 172 cm can hold the handles 70 and 71 located inside the width of the shoulder without bending his wrists when he slightly lowers his waist to lean forward and holds the handles 70 and 71 with his upper arms lowered to a substantially vertical position. Fig.12 Palm flexion and Fig.12 The dorsiflexion state in (c) can be Fig.12 The forearm and fist are straight as in (b) in the figure, so that the grip strength can be exerted most effectively. Of course, it is not necessary to be the same depending on the height, posture, habits, etc. of the person measuring. Fig.12 The position of (b) in the figure can be adjusted roughly without any effort, such as the clamping of the armpit and the angle of the arm. The handles 70 and 71 are used to guide the Fig.12 The guiding role of the state in (b).

[0092] In the case of the figure, the angle θ1 on the right side and the angle θ2 on the left side are the same and are each set to 45 degrees.

[0093] In addition, the surface of the handle 71 that is exposed to the outside, that is, the surface opposite to the insertion space S for inserting the finger, is provided with the mark with the highest brightness in the measuring device body 2. Therefore, in a relatively dark place such as a dim room, Fig.10 As shown, when the cover 62 is opened to take out the measuring device 1 from the storage box 60, the handle 71 is easy to find, and the state of being bent over deeply can be quickly eliminated.

[0094] [About the bulge]

[0095] like Figure 6 and Figure 7 As shown, a bulging portion 80 bulging most forward is formed on the front side of the measuring device body 2 opposite to the handles 70 and 71. In the case of this embodiment, the front side of the measuring device body 2 is recessed in a chamfered manner from the center to the upper side, and the front side of the base 3 is recessed from the center to the lower side, so that the bulging portion 80 is formed when the measuring device 1 is in an upright state.

[0096] Moreover, when the measuring device 1 is in an upright position, the handles 70, 71 and the batteries 38, 39 are located at different positions in the vertical direction with the bulging portion 80 as a reference (boundary). In the case of the figure, the handles 70, 71 are arranged on the upper surface side from the bulging portion 80 ( Figure 4 The batteries 38 and 39 are arranged on the lower surface side from the bulging portion 80 ( Figure 5 bottom side of the device).

[0097] In this way, the front side is placed downward. Fig.13 When the measuring device 1 is taken out of the storage box in the state (storage box not shown), when the handle 71 is lifted, the downward force of the heavier battery 39 side is applied, and the bulged portion 80 becomes a fulcrum. By utilizing the lever principle, it is easy to rotate the handle 71 side upward in the LF direction and lift it, thereby suppressing the application of force in the bent state.

[0098] Furthermore, in order to facilitate lifting of the measuring device, the present embodiment has the following further features.

[0099] [Further Features 1]

[0100] First, in Figure 3 In the upright state shown, the left and right batteries 38 and 39 are respectively arranged directly below the left and right handles 70 and 71. Figure 3 In the embodiment, the right battery 38 is arranged below the right handle 70, and the left battery 39 is arranged below the left handle 71. Therefore, the center of gravity can be brought as close to the handles 70 and 71 as possible, making it easy to hold the heavy measuring device 1. The weight of the battery 38 and the battery 39 are preferably the same.

[0101] [Further Features 2]

[0102] Then, if Figure 3 and Fig.13 As shown in FIG. 1 , a recessed portion 25 is formed on the left and right sides of the measuring device body 2 (in this embodiment, the left and right sides of the bracket 10). The recessed portion 25 is a guide portion for easily guiding the fingers of the hand wearing a glove to the space S between the handles 70 and 71 and the left and right sides of the measuring device body 2. Specifically, when the measuring device 1 is in an upright state, the height H2 ( Fig.13 The horizontal width of the lying state, also refer to Figure 6 ) corresponds to the width of the four fingers except the thumb when wearing gloves. Moreover, the recessed portion 25 is arranged from the central portion of the measuring device body 2 to the upper side ( Figure 4 The upper surface side of the space S) (i.e., the upper side close to the side surface corresponding to the space S). Fig.13 As shown, the measurer is guided to the recessed portion 25 with ample space, and holds the handles 70 and 71 at the position farthest from the batteries 38 and 39, and can easily rotate in the LF direction based on the lever principle.

[0103] In addition, even if only on the upper side ( Figure 4 The same effect as in the present embodiment can be obtained by providing handles 70 and 71 on the upper surface side of the measuring device 1. However, in this case, when the measuring device 1 is placed and fixed on a higher tripod, the handles are only on the upper side and are difficult to operate. Figure 3 In the upright state, the handles 70 and 71 are set larger from the top to the bottom of the measuring device body 2, and the recessed portion 25 serving as a guide for guiding the fingers is set to a height H2 that allows four fingers wearing gloves to enter based on the upper part of the space S.

[0104] [Further feature 3]

[0105] Then, if Figure 6 to Figure 8 As shown, the upper surface of the measuring device body 2 in the upright state (from Figure 4 The area 2A on the front side (the surface viewed from above) is formed into a curved inclined surface that is inclined downward and convex outward. Specifically, the areas 50A and 10A on the front side of the upper surfaces of the lens barrel 50 and the bracket 10 (see Figure 8 ) is formed into a curved inclined surface that is curved in the same manner as described above. Fig.13 As shown, in order to take out the measuring device 1 which is placed in the storage box with the front side having the window portion 28 facing downward, when the measuring device is rotated in the LF direction with the bulge portion 80 as a fulcrum, the measuring device body 2 is prevented from getting stuck in the protective member 63 of the storage box as much as possible, thereby smoothly taking the measuring device 1 out of the storage box.

[0106] In addition, only the narrow-angle camera 58 is not a curved slope. This is because the optical axis of the narrow-angle camera 58 and the optical axis of the laser emitted from the laser emitting unit 52 need to be parallel. Therefore, the case where a part of the curved slope does not exist is also included in the present invention.

[0107] [Further feature 4]

[0108] Then, if Figure 2 and Figure 8 As shown, the lens barrel 50 and the bracket 10 have surfaces 26 and 27 connected to each other on the front side of the periphery of the boundary. The so-called "connected surface" means that although there is a space at the boundary because the lens barrel 50 and the bracket 10 are not in close contact, the surface 26 and 27 are close to each other near the boundary as if they are the same surface. The surfaces 26 and 27 are formed to be connected in this way in order to avoid jamming when taking out from the storage box as much as possible.

[0109] The connected surface is formed in a shape obtained by flatly cutting away the front side of the cylindrical measuring device body 2. This makes it easier for the measurer to hold the front side than when the whole is substantially cylindrical.

[0110] Here, as mentioned above, if the lens barrel 50 and the bracket 10 are the surfaces 26 and 27 connected on the front side, it is difficult to visually confirm the boundary between the lens barrel 50 and the bracket 10 when observing the device from a distance by remote operation or the like. Moreover, originally in the present embodiment, the lens barrel 50 is not exposed from the bracket 10 as much as possible. In this way, in such a structure, it becomes difficult to know the movement of the lens barrel 50. Therefore, in order to easily know the movement of the lens barrel 50, there is the following further feature.

[0111] [Further feature 5]

[0112] First, if Figure 8 , Fig. 9 As shown, the measuring device 1 has indicators 41, 43 composed of LEDs (Light Emitting Diodes) that light up when the lens barrel 50 rotates. The indicators 41, 43 are arranged on the outer surface of the bracket 10 and on the lower side of the lens barrel 50. The indicators 41, 43 in the figure are arranged on the front and back sides and light up with the same color, but they can also light up with different colors on the front and back sides, or light up in different methods such as flashing, so that the front and back sides can be distinguished.

[0113] [Further feature 6]

[0114] Next, in the present embodiment, a continuous pattern is formed from the lens barrel 50 to the bracket 10 , in which the pattern is shifted due to the rotation of the lens barrel 50 .

[0115] Fig.14 is a diagram for explaining the continuous pattern. Fig.14 (A) is the diagram of the undriven state. Fig.14 (B) in FIG. 1 is a diagram in which the lens barrel portion 50 is rotated downward.

[0116] like Fig.14 As shown in (A) in the figure, there is a space between the lens barrel portion 50 and the bracket portion 10, but in the undriven state, the pattern D2 on the bracket portion 10 side of the lens barrel portion 50 is close to the pattern D1 on the lens barrel portion 50 side of the bracket portion 10, thereby forming a continuous pattern DS.

[0117] The continuous pattern DS in the figure is a line or strip pattern formed from the lens barrel 50 to the bracket 10, and is formed in a ring shape so as to surround the window 28, the camera 19, and the camera 58. Therefore, if the lens barrel 50 is rotated in the vertical direction, Fig.14As shown in (B) in the figure, the line and belt D2 of the lens barrel 50 are separated from the line and belt D1 of the bracket 10, and the continuous pattern is deformed, which is known by the movement of the lens barrel 50. In addition, the continuous pattern DS has a uniform color of yellow, making it conspicuous even if the width of the line and belt is narrow.

[0118] [Further Features 7]

[0119] Next, the inner area ( Fig.14 The area (area) of parallel oblique lines GN is a color different from the continuous pattern DS, and is a uniform color except for the upper and lower areas (i.e., the area on the front side of the upper surface and the area on the front side of the lower surface) 50A and 50B of the lens barrel portion 50.

[0120] The color of the inner region GN is preferably a color that is greatly different from the color of the continuous pattern DS. Since the continuous pattern DS of the present embodiment is yellow, the inner region GN is black except for the upper and lower regions 50A and 50B of the lens barrel 50. In addition, the upper and lower regions 50A and 50B of the lens barrel 50 are different in color from the continuous pattern DS and the inner region GN, and are preferably an intermediate color between the color of the continuous pattern DS and the color of the inner region GN, which is silver in the case of the figure.

[0121] Since the inner area GN surrounded by the continuous pattern DS is constructed as described above, Fig.14 As shown in (B) in the figure, when the lens barrel portion 50 is rotated downward, the black color of the inner area GN on the side of the bracket portion 10 does not move. On the other hand, the silver color of the upper area 50A of the lens barrel portion 50 moves in an increasing manner from the top. Conversely, when the lens barrel portion 50 is rotated upward, the silver color of the lower area 50B of the lens barrel portion 50 moves in an increasing manner from the bottom, thereby making it easy to know the movement in the up and down directions.

[0122] The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the claims.

[0123] For example, in Figures 1 to 9 In the figure, a bulge 80 is arranged on the front side where the wide-angle camera 19 is located, and handles 70 and 71 are arranged on the back side opposite to the wide-angle camera 19. However, the positional relationship between the bulge 80 and the handles 70 and 71 is a relative relationship based on the horizontal center OP, and the wide-angle camera 19 is not necessarily the basis for determining the front and back sides.

[0124] In addition, for Figure 15 to Figure 22 In the area shown by the dotted line, the antenna 7 may be built-in, or there may be no antenna. In addition, the batteries 38 and 39 may be combined into one battery. Figure 7The bulging portion 80 is composed of a bulging portion 80A on the side of the measuring device body 2 and a bulging portion 80B on the side of the base portion 3, but the present invention is not limited to this. The bulging portion 80A on the side of the measuring device body 2 can also be used as the bulging portion 80 without forming a bulging portion on the base portion 3.

[0125] Or, in the above embodiment, if Figure 6 As shown in the figure, the portion of the measuring device body 2 above the bulging portion 80 is recessed to form a substantially vertical flat surface, but it may also be as in the modified example. Fig.23 , Fig.24 As in the illustrated measuring device 90 , a portion of the measuring device body 2 above the bulging portion 80 is formed as an inclined surface in which the outer shape of the measuring device body 2 narrows toward the upper surface.

[0126] In addition, Figures 1 to 9 In the measuring device 1, the lens barrel 50 as a whole rotates in the vertical direction, so that the window 28 also rotates, but Fig.23 , Fig.24 In the measuring device 90, the entire surface of the lens barrel 94 exposed to the outside is a transparent window, and the laser emitting portion inside thereof rotates in the vertical direction to emit laser. In addition, the camera 92 of the measuring device 90 has two functions of a wide-angle camera and a narrow-angle camera. The above structure is also included in the present invention.
