[0003] [Patent Document 1] JP 2017-040547 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the above-mentioned conventional buried object detection device has the following problems. In other words, although the buried object detection device disclosed in the above publication is equipped with a display unit that displays a two-dimensional detection image indicating the position, size, etc. of buried objects detected based on position information, the area of ​​the display screen is small, making it difficult to use.

[0005] Also, for example, in order to display a menu screen for performing various settings and an exploration image of a buried object, it is necessary to switch the display screen each time, which poses a problem of poor usability. An object of the present invention is to provide a buried object detection device capable of improving usability by appropriately displaying various information about detected buried objects, etc. [Means for solving the problem]

[0006] A buried object exploration device according to a first aspect of the present invention is a buried object exploration device that detects buried objects contained within a target object, and includes a main body, an attachment, an exploration image conversion processing unit, a first display unit, a second display unit, and a display control unit. The attachment is detachably attached to the main body and has a detection unit that detects buried objects. The exploration image conversion processing unit is provided on the main body and converts a detection result from the detection unit into an exploration image. The first display unit is provided on the main body and has a first display screen that displays various information. The second display unit is provided on the attachment and has a second display screen that displays various information. The display control unit controls the display of the first display unit and the second display unit.

[0007] Here, a main body unit and an attachment unit that is detachably attached to the main body unit are provided with display units (first display unit and second display unit), each having a separate display screen (first display screen and second display screen). Here, the buried object detection device of the present invention may employ various types as a detection section, such as a capacitance type using a capacitance sensor that detects changes in capacitance to detect buried objects, or an electromagnetic wave type that receives electromagnetic waves irradiated to the target object to detect buried objects.

[0008] The display control unit controls the display of the first display unit and the second display unit, and may be provided in either the main body unit or the attachment unit, or may be provided in both the main body unit and the attachment unit. This makes it possible to appropriately switch between the two display screens as needed, for example, by combining the first display screen of the first display unit on the main body side and the second display screen of the second display unit on the attachment unit side to form a large screen, or by displaying different information on the first display screen and the second display screen, respectively. As a result, various types of information about detected buried objects and the like can be appropriately displayed, thereby improving usability.

[0009] The buried object detection device of the second invention is the buried object detection device of the first invention, wherein the first display screen and the second display screen are provided on the same side of the main body part and the attachment part when the attachment part is attached to the main body part. As a result, the display screens (first display screen and second display screen) provided on the main body unit and the attachment unit are provided on the same side when the attachment unit is attached to the main body unit, so that display control can be implemented such as combining the two display screens to create a larger screen or displaying different information on the two display screens.

[0010] The buried object detection device of the third invention is the buried object detection device of the second invention, wherein the first display screen and the second display screen are arranged adjacent to each other when the attachment part is attached to the main body part. This allows two display screens arranged adjacent to each other to be combined to form a large screen.

[0011] A buried object detection device according to a fourth aspect of the present invention is a buried object detection device according to the third aspect of the present invention, in which the display control unit controls the first display unit and the second display unit to display various information on a large display screen combining the first display screen and the second display screen. In this way, by combining the first display screen and the second display screen to form one large screen, it is possible to display an exploration image showing, for example, the position of a buried object in an easily viewable manner for the user.

[0012] A buried object exploration device according to a fifth aspect of the present invention is the buried object exploration device according to the fourth aspect of the present invention, wherein the display control unit controls the first display unit and the second display unit to display the exploration image on the large display screen. This makes it possible to display the exploration image in a state in which the user can easily recognize the position and size of the buried object contained in the exploration image.

[0013] A buried object detection device according to a sixth aspect of the present invention is a buried object detection device according to any one of the first to fifth aspects of the present invention, wherein the display control unit displays different information on the first display screen and the second display screen. This makes it possible to appropriately switch between the two display screens, for example by displaying a search image on the first display screen and displaying a menu screen or an enlarged image of the search image on the second display screen.

[0014] A buried object exploration device according to a seventh aspect of the present invention is a buried object exploration device according to the sixth aspect of the present invention, in which the display control unit controls the first display unit and the second display unit to display the entire exploration image on the first display screen or the second display screen, and to display an enlarged image of an enlarged portion of the exploration image on the second display screen or the first display screen. This allows the user to easily recognize the location, size, etc. of buried objects by displaying the entire exploration image on one of the two display screens and an enlarged image of part of it on the other.

[0015] A buried object exploration device according to an eighth aspect of the present invention is a buried object exploration device according to the sixth aspect of the present invention, in which the display control unit controls the first display unit and the second display unit to display an exploration image on the first display screen or the second display screen, and to display a menu screen for making various settings on the second display screen or the first display screen. This allows the exploration image to be displayed on one of the two display screens, and a menu screen for making various settings to be displayed on the other, allowing the user to make various settings via the menu screen while checking the exploration image.

[0016] A buried object exploration device according to a ninth aspect of the present invention is the buried object exploration device according to any one of the first to eighth aspects of the present invention, wherein the display control unit is provided in either the main body unit or the attachment unit. This makes it possible to control the first display section on the main body side and the second display section on the attachment side by the display control section provided on the main body section or the attachment section.

[0017] A buried object exploration device according to a tenth aspect of the present invention is the buried object exploration device according to any one of the first to eighth aspects of the present invention, wherein the display control unit is provided in both the main body unit and the attachment unit. This makes it possible to separately control the first display section on the main body side and the second display section on the attachment side by the display control sections provided on the main body section and the attachment section, respectively.

[0018] Therefore, for example, when performing an operation of exploring buried objects using only the attachment unit, it is possible to display an exploration image via the second display screen of the attachment unit without attaching it to the main body unit.

[0019] The buried object exploration device according to an eleventh aspect of the present invention is the buried object exploration device according to any one of the first to tenth aspects of the present invention, further comprising an attitude detection unit that detects the attitude of the main body unit or the attachment unit. The display control unit changes the display orientations of the first and second display screens according to the attitude detected by the attitude detection unit. As a result, for example, when the orientation detection unit detects that the main body unit and the attachment unit are in a vertical orientation, the orientation of the display on the first display screen and the second display screen can also be switched to portrait. Therefore, the display orientation can be appropriately changed depending on the position of the device, which improves usability for the user.

[0020] The buried object detection device of the 12th invention is a buried object detection device of any one of the first to 11th inventions, further comprising an attachment mechanism that enables the attachment part to be detachably attached to the main body part.

[0025] A buried object exploration device according to one embodiment of the present invention will be described below with reference to Figs. 1 to 10. (1) Configuration of buried object exploration device 10 As shown in FIG. 1, the buried object detection device 10 of this embodiment is moved along a wall surface (target object) 90 while detecting changes in capacitance value using a capacitance sensor 13 (see FIG. 5) described later, thereby detecting buried objects 91 such as wood (pipe posts 91a, partition walls 91b) and metals contained within the wall surface 90.

[0026] In the buried object exploration device 10 of this embodiment, as shown in FIGS. 2 to 4, an attachment unit 20 including a capacitance-type detection unit (capacitance sensor 13) is detachably attached to a main body unit 11. The attachment unit 20 includes a capacitance sensor 13 (see FIG. 5) that detects changes in capacitance as the buried object detection device 10 is moved along a wall surface 90, thereby detecting a buried object 91, such as wood behind a plasterboard.

[0027] As shown in Figures 2 to 4, the buried object exploration device 10 includes a main body unit 11 (a display unit 12, an optical sensor 14 (see Figure 5) and an operation input unit 15) and a plurality of attachment units 20 that are detachable from the main body unit 11. The wall surface 90 includes, for example, a plaster board or a wooden plywood with an interior material such as wallpaper attached to the surface. The buried object 91 includes, for example, a wooden pillar, a beam, a brace, or a metal frame.

[0028] 3(a) and 3(b), the main body 11 is a resin member having a substantially rectangular parallelepiped shape, and has a display unit (first display unit) 12 and an operation input unit 15 provided on its surface (front side) facing the user when in use, and an optical sensor 14 provided on its surface (back side) facing the wall surface 90 opposite the user. In addition, an attachment unit 20 including multiple types of detection units (sensors) with different detection methods, for example, is detachably attached to the upper end of the main body 11 as shown in FIG.

[0029] The display unit 12 is, for example, a liquid crystal display device, and has a display screen (first display screen) 12a arranged on the surface of the main body unit 11, as shown in Fig. 2 etc. The display unit 12 displays, for example, settings of the buried object exploration device 10, an exploration image showing the detection result of the buried object 91, etc. (see Fig. 6(a) etc.), and the display contents are switched according to the operation contents input to the operation input unit 15.

[0030] The capacitance sensor 13 is arranged on the back side of the attachment part 20, and detects a change in capacitance when the buried object detection device 10 is moved along the wall surface 90 in order to detect a buried object 91 present within the wall surface 90. The optical sensor 14 is disposed on the rear side of the main body 11 and receives, for example, infrared light reflected from the wall surface 90 to obtain position information of the buried object exploration device 10 .

[0031] 2 to 4, the operation input unit 15 is disposed on the surface of the main body unit 11. The operation input unit 15 includes a power button 15a and a search button 15b. The power button 15a is located on the right side of the operation input unit 15, and, for example, when pressed and held, the power of the buried object exploration device 10 is turned on or off. The search button 15b is located on the left side of the operation input unit 15, and is pressed, for example, when searching for a buried object 91 with the buried object exploration device 10 abutted against a wall surface 90.

[0032] In addition, as shown in Figure 5, the buried object detection device 10 includes, inside the main body 11, a capacitance acquisition unit 30, a position information acquisition unit 31, a memory unit 32, a buried object presence / absence determination unit 33, a dimension calculation processing unit 34, an detection image conversion processing unit 35, a buried object estimation unit 36, an input acceptance unit 37, an detection image calling unit 38, a data transfer unit 39, a display control unit 40 and an attitude detection unit 41. The capacitance acquisition unit 30, position information acquisition unit 31, memory unit 32, buried object presence / absence determination unit 33, dimension calculation processing unit 34, exploration image conversion processing unit 35, buried object estimation unit 36, input acceptance unit 37, exploration image calling unit 38, data transfer unit 39, display control unit 40 and attitude detection unit 41 generated within the buried object detection device 10 are generated as control blocks by the CPU reading various control programs stored in the memory.

[0033] The capacitance acquisition unit 30 acquires, for example, a capacitance value output from the capacitance sensor 13 arranged on the back side of the attachment unit 20 , and transmits the capacitance value to the storage unit 32 . More specifically, the capacitance acquisition unit 30 detects a change in the capacitance value to determine the presence or absence of a buried object 91 in the movement range of the buried object exploration device 10 using the position information acquired by the position information acquisition unit 31, each time the buried object exploration device 10 reaches a predetermined movement amount along the wall surface 90. As a result, the exploration image conversion processing unit 35 described later can generate an exploration image of the movement area for each predetermined movement amount, using the output result from the capacitance sensor 13.

[0034] The position information acquisition unit 31 acquires the output from the optical sensor 14 arranged on the back side of the main body unit 11, and transmits it to the storage unit 32. In this way, the position information acquired by the position information acquisition unit 31 enables the buried object exploration device 10 to detect its position on the wall surface 90, as well as its amount of movement and direction of movement. The storage unit 32 stores the capacitance value data and position information data received from the capacitance acquisition unit 30, a buried object table including dimensional information of the buried object 91 in the scanning direction of the buried object exploration device 10, the exploration image converted from the capacitance data in the exploration image conversion processing unit 35, a grid layer displayed superimposed on the exploration image, a reference point display layer, etc. Then, the storage unit 32 transmits the exploration image, etc. called up by the exploration image calling unit 38 to the data transfer unit 39 and the display control unit 40.

[0035] The exploration images stored in the storage unit 32 are grouped in units of one scan and stored together with time information of scanning the wall surface 90. In this embodiment, exploration images corresponding to multiple scans are stored in the storage unit 32. In addition, the exploration images converted for each specified amount of movement are accumulated and stored, for example, after the buried object exploration device 10 is turned on, and multiple exploration images are saved in a grouped state for each scan.

[0036] The buried object presence / absence determining unit 33 determines the presence / absence of a buried object 91 in the wall surface 90 depending on whether the detected capacitance value exceeds a predetermined threshold value (edge ​​determination process). This makes it possible to determine the presence / absence of a buried object 91 based on the output result of the capacitance sensor 13. The dimension calculation processor 34 calculates an estimated value of the dimension (width, etc.) of the buried object 91 in the wall surface 90 based on the capacitance value detected by the capacitance sensor 13. Specifically, the dimension calculation processor 34 detects the edge portions at both ends where the output signal of the capacitance sensor 13 changes, and calculates an estimated value of the dimension of the buried object 91 between them.

[0037] The exploration image conversion processing unit 35 converts the capacitance value detected by the capacitance sensor 13 into an exploration image indicating the presence or absence of a buried object 91. More specifically, the exploration image conversion processing unit 35 generates an exploration image based on the position information of the buried object exploration device 10 detected by the position information acquisition unit 31 described above, using the capacitance value acquired each time the movement amount of the buried object exploration device 10 along the wall surface 90 reaches a predetermined distance.

[0038] The buried object estimation unit 36 ​​compares the estimated value of the dimension (width) in the scanning direction of the buried object 91 calculated by the dimension calculation processing unit 34 with the width dimensions for each type of buried object 91 contained in the buried object table stored in the memory unit 32, and estimates the type of the corresponding buried object 91. The input receiving unit 37 receives operation contents input by the user to the operation input unit 15 including the power button 15a, the search button 15b, and the like described above.

[0039] The exploration image recall unit 38 recalls the exploration image stored in the memory unit 32, for example, based on the operation content input by the user via the operation input unit 15, and transmits it to the data transfer unit 39 and the display control unit 40. In addition, after the exploration image is stored in the memory unit 32, the display control unit 40 may control the display unit 12 so that it is displayed in real time during scanning by the buried object exploration device 10, regardless of the operation content from the user input to the operation input unit 15.

[0040] The data transfer unit 39 transmits the exploration image, the detection results of the buried object 91, and the like to an external device, a server, or the like. The display control unit 40 causes the exploration image indicating the presence or absence of the buried object 91, generated in the exploration image conversion processing unit 35, to be displayed on the display screen 12a of the display unit 12 on the main body unit 11 side. Furthermore, the display control unit 40 causes the exploration image and the grid layer and reference point display layer stored in the storage unit 32 to be superimposed and displayed on the display screen 12a of the display unit 12.

[0041] Furthermore, the display control unit 40 switches the display orientation of information to be displayed on the display screen 12a of the display unit 12 according to the orientation of the main body unit 11 detected by an orientation detection unit 41, which will be described later. In the exploration image, the buried object 91 is displayed by combining a plurality of exploration images generated from capacitance values ​​acquired along the trajectory of the buried object exploration device 10 scanned along the wall surface 90. Also, in the exploration image, for example, the position where the buried object 91 is present is displayed in black, and the position where the buried object 91 is not present is displayed in white, in different colors or gradations.

[0042] The attitude detection unit 41 is provided to detect the attitude of the main body unit 11, and detects, for example, the portrait orientation shown in Fig. 6(a) and the landscape orientation shown in Fig. 6(b). As a result, depending on the attitude of the main body unit 11 detected by the attitude detection unit 41, in the case of the portrait orientation shown in Fig. 6(a), the exploration image, etc. can be displayed in portrait orientation on the display screen 12a, and in the case of the landscape orientation shown in Fig. 6(b), the exploration image, etc. can be displayed in landscape orientation on the display screen 12a.

[0043] In the buried object exploration device 10 of this embodiment, a display control unit (second display control unit) 21 and a display unit (second display unit) 22 are provided on the attachment unit 20 side, as shown in FIG. The display control unit 21, like the display control unit 40 on the main body unit 11 side described above, causes the exploration image indicating the presence or absence of the buried object 91 generated in the exploration image conversion processing unit 35 to be displayed on the display screen 22a of the display unit 22 on the attachment unit 20 side. Furthermore, the display control unit 21 causes the exploration image and the grid layer and reference point display layer stored in the storage unit 32 to be superimposed and displayed on the display screen 22a of the display unit 22.

[0044] Furthermore, the display control unit 21 switches the display orientation of information to be displayed on the display screen 22a of the display unit 22 according to the orientation of the main body unit 11 detected by the orientation detection unit 41 on the main body unit 11 side described above. The display unit 22 is, for example, a liquid crystal display device, and has a display screen 22a arranged on the surface of the attachment unit 20, as shown in Fig. 2 etc. The display unit 22 displays, for example, settings of the buried object exploration device 10, an exploration image showing the detection result of the buried object 91, etc. (see Fig. 6(a) etc.), and the display contents are switched according to the operation contents input to the operation input unit 15.

[0045] 2 to 4, the display screens 22a are provided adjacent to each other on the same side as the display screen 12a on the main body 11. That is, when the attachment unit 20 is attached to the main body 11, the two display screens 12a, 22a are disposed adjacent to each other, and the two display screens 12a, 22a are combined to form a large screen. The display control on the two display screens 12a and 22a included in the buried object exploration device 10 of this embodiment will be described in detail later.

[0046] <Detachable mechanism 50> In the buried object exploration device 10 of this embodiment, the attachment part 20 is attached to the main body part 11 via an attachment / detachment mechanism 50, as shown in FIG.

[0047] As shown in FIG. 4, the attachment / detachment mechanism 50 has a pair of magnets 51a and 51b. The magnet 51a is disposed on the side of the main body 11 that is connected to the attachment part 20. The magnet 51b is disposed on the attachment portion 20 side at a position facing the magnet 51a on the main body portion 11 side.

[0048] As a result, when the attachment part 20 is attached to the main body part 11, the magnetic force of the magnets 51a, 51b acts to attract each other, thereby maintaining the attachment part 20 held in place by the main body part 11 and allowing it to be easily attached and detached. On the inside of both side surfaces of the housing portion of the main body 11, guide ribs (guide mechanisms) 54a are provided which are formed substantially parallel to the mounting direction of the attachment portion 20.

[0049] The guide ribs 54a are convex portions formed so as to protrude inward from both side surfaces of the housing portion of the main body 11, and engage with guide grooves 53c on the attachment portion 20 side, which will be described later. The main body 11 includes a display unit 12 (display screen 12a), a connector 52a electrically connected to the capacitance sensor 13 on the attachment unit 20 side, and a guide hole 52b into which a guide pin 53b on the attachment unit 20 side described later is inserted.

[0050] The connector 52a is connected to a connector 53a of the floating substrate 53 on the attachment part 20 side, thereby acquiring the value of the electrostatic capacitance detected on the attachment part 20 side. The guide holes 52b are provided on both sides of the connector 52a and are holes formed substantially parallel to the mounting direction of the attachment part 20. A guide pin 53b on the attachment part 20 side, which will be described later, is inserted into the guide holes 52b.

[0051] As shown in FIG. 4, the attachment part 20 has a floating substrate 53. Furthermore, the attachment part 20 has guide grooves (guide mechanisms) 53c on the outer sides of both side surfaces of the housing part. The guide groove (guide mechanism) 53c engages with the guide rib 54a on the main body 11 side described above, and guides the attachment part 20 in the mounting direction relative to the main body 11. The guide grooves 53c are formed on the outer sides of both side surfaces of the housing part of the attachment part 20, approximately parallel to the mounting direction of the attachment part 20 relative to the main body 11.

[0052] As shown in FIG. 4, the floating substrate 53 has a connector 53a and a guide pin 53b. When the attachment unit 20 is attached to the main body unit 11, the connector 53a is connected to the connector 52a on the main body unit 11 side. As a result, capacitance data and the like are transmitted to the main body unit 11 side.

[0053] The guide pin 53b is a rod-shaped member that protrudes from the surface of the floating substrate 53 that is attached to the main body portion 11, and is positioned so that when the attachment portion 20 is attached to the main body portion 11, it reaches the main body portion 11 side before the connector 53a. As a result, when the attachment part 20 is attached to the main body part 11, the connector 53a of the floating substrate 53 is connected to the connector 52a on the main body part 11 side in an aligned state by inserting the tip of the guide pin 53b into the guide hole 52b on the main body part 11 side.

[0054] As described above, in the buried object exploration device 10 of this embodiment, the attachment mechanism 50 is provided between the main body 11 and the attachment part 20 that is detachably attached to the main body 11. The attachment mechanism 50 has a magnet 51a provided on the main body 11 side and a magnet 51b provided on the attachment part 20 side. As a result, when the attachment part 20 is attached to the main body part 11, the attachment part 20 is attracted to the main body part 11 by the magnetic force of the magnets 51a and 51b. Therefore, the attachment part 20 can be detachably attached to the main body part 11 and can be maintained in an attached state.

[0055] The attachment / detachment mechanism 50 also includes a floating substrate 53 including a guide pin 53b formed along the mounting direction of the attachment part 20 to the main body part 11, and a guide hole 52b provided in the main body part 11 into which the guide pin 53b is inserted. As a result, the attachment part 20 is positioned relative to the main body part 11 by inserting the floating substrate 53 on the attachment part 20 side so that the guide pin 53b is inserted into the guide hole 52b provided on the main body part 11 side. Therefore, with the attachment part 20 mounted on the main body part 11, the connector 53a of the floating substrate 53 on the attachment part 20 side can be easily connected to the connector 52a on the main body part 11 side.

[0056] Furthermore, the attachment / detachment mechanism 50 includes a guide mechanism that guides the attachment part 20 to a connection position where the capacitance sensor 13 of the attachment part 20 and the main body part 11 are connected to each other. The guide mechanism includes guide ribs 54a provided on the inside of both sides of the housing portion on the main body 11 side, and guide grooves 53c provided on the outside of both sides of the housing portion on the attachment portion 20 side with which the guide ribs 54a engage.

[0057] As a result, the attachment part 20 is guided to a position where the capacitance sensor 13 on the attachment part 20 side and the main body part 11 are connected to each other by engaging with the guide rib 54a and the guide groove 53c, so that the attachment part 20 can be attached to a predetermined position relative to the main body part 11. The guide rib 54a and the guide groove 53c are provided substantially parallel to the mounting direction of the attachment part 20 to the main body part 11. Thereby, the attachment part 20 can be guided in the direction in which it is attached to the main body part 11 by moving the guide rib 54a along the guide groove 53c.

[0058] <Display control using display screens 12a and 22a> As described above, the buried object detection device 10 of this embodiment is equipped with a display unit 12 (display screen 12a) provided on the main body unit 11 side, and a display unit 22 (display screen 22a) provided on the attachment unit 20 side which can be attached to the main body unit 11 in a detachable manner.

[0059] The display contents of these two display screens 12a and 22a are controlled by display control units 40 and 21 that perform display control of the display units 12 and 22, respectively. Specifically, the two display screens 12a and 22a are combined to form one large screen, and display-controlled so that the entire exploration image is displayed on the single large screen, as shown in FIG. 6(a). Here, when the orientation detection unit 41 detects that the main body unit 11 has changed from the portrait orientation shown in Figure 6(a) to the landscape orientation of the main body unit 11 shown in Figure 6(b), the display control units 40, 21 switch the exploration image displayed on the large screen from portrait to landscape orientation.

[0060] Furthermore, the two display screens 12a and 22a may be controlled by the display control units 40 and 21 so as to perform separate displays, respectively. Specifically, as shown in FIG. 7, the display content may be controlled by the display control units 40, 21 so that the entire exploration image corresponding to one scan is displayed on the display screen 22a on the attachment unit 20 side, and a magnified portion of the exploration image is displayed on the display screen 12a on the main body unit 11 side.

[0061] Thereby, for example, by enlarging a portion of the exploration image including the buried object 91 and displaying it on the display screen 12a, the user can easily grasp the position, size, etc. of the buried object 91. Furthermore, as shown in FIG. 8, the display content may be controlled by the display control units 40, 21 so that a menu screen for performing various settings is displayed on the display screen 22a on the attachment unit 20 side, and an exploration image including a buried object 91 is displayed on the display screen 12a on the main body unit 11 side.

[0062] This allows various settings to be made via the menu screen while the exploration image including the buried object 91 is displayed. Furthermore, as shown in FIG. 9, the display content may be controlled by the display control units 40, 21 so that an exploration image including a buried object 91 is displayed on the display screen 22a on the attachment unit 20 side, and a design drawing of the wall surface 90 on which the buried object exploration device 10 was operated is displayed on the display screen 12a on the main body unit 11 side.

[0063] This makes it possible to check the position, size, etc. of the buried object 91 included in the exploration image while displaying the design drawing. In addition, in the buried object detection device 10 of this embodiment, as shown in Figure 10, by scanning along a wall surface 90 with the attachment part 20 detached from the main body part 11, the change in capacitance detected by the capacitance sensor 13 can be detected and a detection image including the buried object 91 can be displayed.

[0064] In this case, the display control unit 21 provided on the attachment unit 20 side receives the exploration image from the main body unit 11 side and controls the display content of the display screen 22a of the display unit 22, making it possible to use the attachment unit 20 alone.

[0065] [Other embodiments] Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the gist of the invention. (A) In the above embodiment, the buried object exploration device 10 including the attachment unit 20 including the capacitance type detection unit has been described as an example. However, the present invention is not limited to this. For example, instead of a capacitance-type detector, the buried object exploration device may be provided with an attachment unit that includes a detector of another type, such as an electromagnetic induction type.

[0066] (B) In the above embodiment, an example has been described in which the display unit 12 on the main body unit 11 side and the display unit 22 on the attachment unit 20 side are respectively controlled by separate display control units 40, 21. However, the present invention is not limited to this. For example, a single display control unit provided only on the main body unit may control the display of both the display unit on the main body unit side and the display unit on the attachment unit side. Alternatively, a single display control unit provided only on the attachment unit may control the display of both the display unit on the main body unit side and the display unit on the attachment unit side.

[0067] (C) In the above embodiment, an example has been described in which the display screen 12a on the main body 11 side and the display screen 22a on the attachment 20 side are disposed on the same side of the buried object exploration device 10. However, the present invention is not limited to this. For example, the display screen on the main body side and the display screen on the attachment side may be arranged on different surfaces of the buried object exploration device.

[0068] (D) In the above embodiment, an example has been described in which the display screen 12a on the main body 11 side and the display screen 22a on the attachment 20 side are disposed adjacent to each other on the same side of the buried object exploration device 10. However, the present invention is not limited to this. For example, the display screen on the main body side and the display screen on the attachment side may be arranged at positions spaced apart from each other on the same side of the buried object exploration device.

[0069] (E) In the above embodiment, an example has been described in which a mechanism that utilizes attraction by the magnetic force of a magnet is used as the attachment mechanism for detachably attaching the attachment unit 20 to the main body unit 11. However, the present invention is not limited to this. For example, instead of attraction by the magnetic force of a magnet, the attachment mechanism may be a mechanical mechanism that combines a locking claw and a locked portion to maintain the attachment state of the attachment part relative to the main body part.

[0070] (F) In the above embodiment, an example has been described in which display control is performed to switch the display orientation of the display screens 12a and 22a in accordance with the orientation of the main body 11 detected by the orientation detection unit 41. However, the present invention is not limited to this. For example, the attitude detection unit may be disposed on the attachment unit side instead of on the main body unit.

[0071] Moreover, a configuration may be adopted in which the attitude detection unit is provided in both the main body unit and the attachment unit, and the attitudes of both the main body unit and the attachment unit are detected. Furthermore, a configuration may be possible in which there is no orientation detection unit, and the display orientation is maintained in a constant direction without being switched even if the orientation (orientation) of the buried object exploration device changes.
