Description

[Technical Field]

[0001] The present invention relates to a technique for inspecting whether or not exterior wall tiles of a building (for example, an apartment building) are peeling off. [Background technology]

[0002] Percussion testing is a method for checking whether or not the tiles that make up the exterior walls of a building (hereinafter simply referred to as exterior wall tiles) have peeled off. In a percussion test, an inspector taps (for example, taps or scrapes) each exterior wall tile with a tapping rod, listens to the percussion sounds that are produced, and determines whether or not the exterior wall tiles have peeled off based on the differences in the sounds.

[0003] Meanwhile, Patent Document 1 discloses a tile soundness determination device. This tile soundness determination device acquires frequency characteristics consisting of sound pressure levels in each frequency band based on the sound produced when an exterior wall tile is tapped with a tapping rod, and determines the soundness of the exterior wall tile based on these frequency characteristics. This makes it possible for even those with no experience in making judgments based on the sound of a tapping inspection to make a determination. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2021-38935 Summary of the Invention [Problem to be solved by the invention]

[0005] Conventionally, to check whether exterior wall tiles are peeling off, one needs the experience to distinguish between different tapping sounds, or a dedicated tile soundness determination device such as that disclosed in Patent Document 1.

[0006] Therefore, the object of the present invention is to enable even a person who has no experience in distinguishing between different percussion sounds to check whether or not exterior wall tiles have peeled off, without using a dedicated device for determining whether or not exterior wall tiles have peeled off. [Means for solving the problem]

[0007] In order to achieve the above object, according to the present invention, there is provided a mobile terminal, a sensor capable of detecting vibrations caused by tapping on an exterior wall tile; a storage device that stores a peeling inspection application program for determining whether or not an exterior wall tile is peeling; and a processing device that determines whether or not an exterior wall tile is peeling based on the vibration detected by the sensor in accordance with the peeling inspection application program.

[0008] In order to achieve the above object, according to the present invention, there is provided a case for covering the main body of the above-mentioned mobile terminal, the case including: The tapping portion has a hard material for tapping the exterior wall tile, A case is provided in which the percussion portion is provided on the case so as to be located outside the case.

[0009] In order to achieve the above object, the present invention provides a mobile terminal device including the above mobile terminal and the above case.

[0010] In order to achieve the above object, according to the present invention, there is provided a peeling inspection application program for causing a processing device of a mobile terminal to execute an exterior wall tile peeling inspection process, the program comprising: A peeling inspection application program is provided that, when a sensor in a mobile terminal detects vibrations caused by tapping an exterior wall tile with the mobile terminal, causes a processing device to execute a determination process to determine whether or not the exterior wall tile has peeled off based on the detected vibrations. [Effects of the Invention]

[0011] According to the present invention, a peeling inspection application program is stored in the storage device of a mobile terminal, and a processing device of the mobile terminal determines whether or not an exterior wall tile has peeled off based on the vibrations detected by the sensor when the exterior wall is tapped in accordance with the peeling inspection application program. In this way, by tapping the exterior wall tile and processing the vibrations generated at that time using the sensor and processing device provided in the mobile terminal, it is possible to determine whether or not an exterior wall tile has peeled off. Therefore, by installing the peeling inspection application program in a mobile terminal, even a person who has no experience in distinguishing between different percussion sounds can inspect whether or not an exterior wall tile has peeled off using a mobile terminal that is not dedicated to determining whether or not there is peeling.

[Figure 5D] 5D-5D cross-sectional view of FIG. 5B. DETAILED DESCRIPTION OF THE INVENTION

[0013] An embodiment of the present invention will be described with reference to the drawings. In addition, common parts in the drawings are given the same reference numerals, and duplicated explanations will be omitted.

[0014] 1 shows a mobile terminal device 100 according to an embodiment of the present invention. The mobile terminal device 100 includes a mobile terminal 10 and a case 20 in which the mobile terminal 10 is attached.

[0015] A peeling inspection application program is installed in the mobile terminal 10. The peeling inspection application program causes a processing device 17 (described later) of the mobile terminal 10 to execute a process of determining whether or not exterior wall tiles 2 affixed to an exterior wall surface 1 of a building are peeling off from the exterior wall surface 1 (hereinafter simply referred to as the presence or absence of peeling).

[0016] Based on the vibrations (e.g., acceleration or tapping sound of the mobile terminal 10) generated by tapping the exterior wall tile 2 with the mobile terminal 10 for inspecting whether the exterior wall tile 2 has peeled off, the processing device 17 of the mobile phone performs processing to determine whether the exterior wall tile 2 has peeled off in accordance with a peeling inspection application program.

[0017] In this application, "tapping the exterior wall tile 2" may mean tapping the exterior wall tile 2 (e.g., lightly) with the tapping part 24 described below, or may mean rubbing the exterior wall tile 2 with the tapping part 24 described below (e.g., rubbing multiple exterior wall tiles 2 in succession).

[0018] (Mobile device configuration) The mobile terminal 10 is a device into which a peel inspection application program can be installed and which can be carried by hand. Furthermore, the mobile terminal 10 may have installed thereon a plurality of application programs other than the peel inspection application program. That is, the mobile terminal 10 has a function corresponding to each of the other plurality of application programs. The function may be realized by a processing device 17 of the mobile terminal 10, which will be described later, executing processing in accordance with the application program corresponding to the function.

[0019] The mobile terminal 10 may be a smartphone having the above-mentioned functions, such as a calling function for making wireless calls to other mobile terminals or landlines, and various other functions (such as an Internet connection function and a photographing function using a digital camera 14). However, according to the present invention, the mobile terminal 10 is not limited to a smartphone, and may be, for example, a mobile phone other than a smartphone, a PDA (personal digital assistant), a tablet, etc.

[0020] 2 is a block diagram showing the configuration of a mobile terminal 10 according to this embodiment. The mobile terminal 10 may include an operation unit 11, a display 12, a wireless communication unit 13, a camera 14, a sensor 15, a storage device 16, and the processing device 17 described above.

[0021] The operation unit 11 is operated by a user and receives input corresponding to the operation. For example, the operation unit 11 may have a touch panel provided on the display 12. The touch panel receives input corresponding to an operation performed on the touch panel (for example, the movement of a finger or a touch pen on the display 12). Note that the operation unit 11 is not limited to a touch panel and may have other configurations. For example, the operation unit 11 may have operation buttons in addition to or instead of the touch panel. The processing device 17 executes processing based on the input received by the operation unit 11 in accordance with an application program corresponding to the input.

[0022] If the display 12 is provided with the above-mentioned touch panel, icons of various application programs may be displayed on the display 12 so that they can be operated using the touch panel. By operating the icon on the touch panel, the application program may be launched by the processing device 17. Similarly, when a peel inspection application program is downloaded to the mobile terminal 10 as described above and stored in the storage device 16 so as to be usable by the mobile terminal 10, an icon of the peel inspection application program may be displayed on the display 12. By a person operating the icon on the display 12, the peel inspection application program may be launched by the processing device 17.

[0023] The wireless communication unit 13 is hardware for realizing the above-mentioned telephone function and Internet connection function. The wireless communication unit 13 is configured to be able to communicate with various devices via a base station and a communication network. The communication network may include the Internet and a telephone network.

[0024] The camera 14 captures an image and generates an image in accordance with the operation of the operation unit 11. The generated image may be stored in a predetermined storage area in the mobile terminal 10.

[0025] The sensor 15 is capable of detecting vibrations caused by tapping the exterior wall tile 2 with the mobile terminal 10. This sensor 15 does not have to be a sensor dedicated to the exterior wall tile peeling inspection process by the peeling inspection application program, but may also be used to realize other functions of the mobile terminal 10.

[0026] The sensor 15 may be an acceleration sensor 15a that detects the acceleration of the mobile terminal 10 (that is, its main body 10a) as the vibration, or may be a sound sensor 15b that detects sound (sound waves) as the vibration.

[0027] Acceleration sensor 15a detects acceleration of main body 10a of mobile terminal 10 in a detection direction (hereinafter simply referred to as a detection direction) fixed to main body 10a of mobile terminal 10. Acceleration sensor 15a may detect acceleration in each of a plurality of detection directions. In this case, the plurality of detection directions may be the horizontal direction, vertical direction, and thickness direction of main body 10a. The horizontal direction and the vertical direction may respectively coincide with the horizontal direction and vertical direction of display 12, and the thickness direction may be a direction perpendicular to display 12 (its screen).

[0028] Such acceleration sensor 15a may be used for a screen rotation function or a step counting function included in the various functions described above. The screen rotation function is a function that determines the direction of gravitational acceleration based on the acceleration in each detection direction detected by acceleration sensor 15a, and switches the screen orientation of display 12 between portrait and landscape based on this determination result. The step counting function is a function that counts the number of steps taken by the person holding mobile terminal 10 based on the acceleration in each detection direction detected by acceleration sensor 15a.

[0029] The sound sensor 15b is a microphone that detects sounds outside the mobile terminal 10. The sound sensor 15b may be, for example, the one used for the above-mentioned call function.

[0030] The storage device 16 stores a peel inspection application program installed in the mobile terminal 10. The storage device 16 may also store various other application programs installed in the mobile terminal 10. Furthermore, the storage device 16 may have a storage unit that stores the operating system (OS) of the mobile terminal 10.

[0031] The peeling inspection application program may be downloaded to the mobile terminal 10 by the wireless communication unit 13 from a predetermined server device via a communication network (for example, the Internet), and thereby installed in the mobile terminal 10.

[0032] Processing device 17 executes processing in accordance with each application program stored in storage device 16 by activating the application program. Processing device 17 may execute each application program via the operating system described above. Processing device 17 and storage device 16 may constitute control device 18 that receives input from hardware elements of mobile terminal 10 (e.g., operation unit 11 or acceleration sensor 15a) and controls the operation of hardware elements of mobile terminal 10 (e.g., display 12, wireless communication unit 13, camera 14, etc.) based on the input.

[0033] (Mobile device case) Fig. 3A shows a case 20 according to an embodiment of the present invention and a main body 10a of a mobile terminal 10 removed from the case 20. Fig. 3B is a cross-sectional view taken along line 3B-3B of Fig. 3A, and Fig. 3C is a cross-sectional view taken along line 3C-3C of Fig. 3A. In Figs. 3B and 3C, the two-dot chain line indicates the main body 10a of the mobile terminal 10 when the main body 10a is attached inside the case 20. As shown in these figures, the main body 10a may have a plate shape.

[0034] The case 20 has the main body 10a of the mobile terminal 10 attached to its inside, covering the main body 10a. That is, when the main body 10a is attached to the inside of the case 20 (hereinafter simply referred to as the attached state), the case 20 covers at least a portion of the mobile terminal 10 (for example, the outer peripheral surface 10b and back surface of the main body 10a) and protects the mobile terminal 10 from external impact to that at least portion. In the attached state, the user may be able to operate the operation unit 11 and view the screen of the display 12. The case 20 may have an outer peripheral cover portion 21, a back surface portion 22, and an engagement portion 23.

[0035] In the attached state, the outer circumferential cover part 21 covers the outer circumferential surface 10b of the main body 10a of the mobile terminal 10. In the attached state, the outer circumferential cover part 21 may extend along the outer circumferential surface 10b of the main body 10a of the mobile terminal 10 (for example, around the entire periphery of the main body 10a).

[0036] In the attached state, the back surface portion 22 covers the back surface of the mobile terminal 10. The outer peripheral cover portion 21 is formed to rise from the outer peripheral edge of the back surface portion 22. The back surface portion 22 may be formed with a hole 22a for capturing an image of the camera 14 provided on the back side of the main body 10a of the mobile terminal 10.

[0037] The engaging portion 23 is coupled to the tip of the outer peripheral cover portion 21 on the side opposite to the back surface portion 22. In the attached state, the engaging portion 23 engages with the outer peripheral portion of the main body 10a of the mobile terminal 10 so as to sandwich the outer peripheral portion between the engaging portion 23 and the back surface portion 22. This prevents the main body 10a of the mobile terminal 10 from coming off the case 20. In the attached state, the engaging portion 23 extends along the outer peripheral portion of the main body 10a (for example, along the entire circumference), and its inner peripheral edge defines an opening 23a of the case 20. In the attached state, the display 12 may be located within the opening 23a.

[0038] The elastic deformation of engagement portion 23 allows main body 10a of mobile terminal 10 to be attached to case 20 through opening 23a. Outer cover portion 21, back surface portion 22, and engagement portion 23 may be formed from an impact-resistant material (for example, silicone, thermoplastic polyurethane, or polycarbonate).

[0039] The case 20 is provided with a percussion portion 24 for percussing the exterior wall tiles 2. The percussion portion 24 is provided on the case 20 so as to be located outside the case 20. The percussion portion 24 may be provided on the outer surface of the outer periphery cover portion 21. As shown in FIGS. 3A and 3C , the percussion portion 24 may be provided on the outer surface of a corner portion of the outer periphery cover portion 21.

[0040] The percussion portion 24 is formed of a hard material for percussing the exterior wall tile 2. The hard material is harder than the material of the case 20 (outer peripheral cover portion 21). The hard material may be a metal (for example, iron).

[0041] In the installed state, when the mobile terminal 10 is used to tap the exterior wall tile 2, the tapping portion 24 directly taps the exterior wall tile 2, so that the main body 10a of the mobile terminal 10 does not directly collide with the exterior wall tile 2. In other words, the mobile terminal 10 indirectly taps the exterior wall tile 2 via the tapping portion 24. Therefore, when the mobile terminal 10 is used to tap the exterior wall tile 2, a part of the case 20 (outer peripheral cover portion 21), which is made of an impact-resistant material, is interposed between the tapping portion 24, which directly hits the exterior wall tile 2, and the main body 10a of the mobile terminal 10. This makes it possible to protect the main body 10a when tapping.

[0042] (Processing by peel inspection application program) When the processing device 17 executes the peeling inspection application program, the peeling inspection application causes the processing device 17 to execute the exterior wall tile peeling inspection process. In the following, the "sensor 15" and "vibration" may respectively refer to the "acceleration sensor 15a" and the "acceleration of the mobile terminal 10 (main body 10a)", or the "sound sensor 15b" and the "sound".

[0043] The exterior wall tile peeling inspection process includes a determination process for determining whether or not the exterior wall tile 2 has peeled off, based on the detected vibrations when the sensor 15 of the mobile terminal 10 detects the vibrations caused by tapping the exterior wall tile 2 with the mobile terminal 10. Here, the presence or absence of peeling may mean whether or not the peeling of the exterior wall tile 2 has progressed to a predetermined degree or more. For example, it may mean whether or not a predetermined percentage or more of the rear surface of the exterior wall tile 2 has peeled off from the exterior wall surface 1. The predetermined percentage may be a predetermined percentage of the total area of ​​the rear surface of the exterior wall tile 2.

[0044] 4 is a flowchart showing the exterior wall tile peeling inspection process. The exterior wall tile peeling inspection process may include the startup process, the above-mentioned determination process, notification process, and display process, which are executed in steps S1 to S4, respectively. That is, the peeling inspection application may cause the processing device 17 to execute the startup process S1, the determination process S2, the notification process S3, and the display process S4.

[0045] The processing device 17 may start the peel inspection application program when the user of the mobile terminal 10 performs an operation to start the peel inspection application program on the operation unit 11. For example, the user touches the icon of the peel inspection application program displayed on the screen of the display 12, causing the processing device 17 to start the program.

[0046] When the peeling inspection application program is started, it causes the processing device 17 to start the exterior wall tile peeling inspection process (ie, steps S1 to S4).

[0047] In the activation process S1, the processing device 17 activates the sensor 15. However, if the sensor 15 is already activated when the activation process S1 is performed, the processing device 17 leaves the sensor 15 operating.

[0048] Next, the user taps the exterior wall tile 2 to be inspected using the mobile terminal 10. In this embodiment, with the mobile terminal 10 attached to the inside of the case 20, the tapping portion 24 of the case 20 directly taps the exterior wall tile 2, thereby indirectly tapping the exterior wall tile 2 using the main body 10a of the mobile terminal 10.

[0049] In the determination process S2, the processing device 17 determines whether or not the exterior wall tile 2 has peeled off, based on the vibration detected by the sensor 15 in this manner.

[0050] Here, if the sensor 15 is an acceleration sensor 15a, the vibration used in the determination process S2 may be acceleration in any of the above-mentioned multiple detection directions. For example, if the percussion part 24 is provided on the outer surface of the outer circumferential cover part 21, the vibration used in the determination process S2 may be acceleration in the horizontal or vertical direction of the main body 10a as the detection direction. Alternatively, if the sensor 15 is an acceleration sensor 15a, the vibration used in the determination process S2 may be acceleration in a predetermined direction different from the above-mentioned multiple detection directions. The predetermined direction may be a direction that makes it easy for a person holding the mobile terminal device 100 to apply the percussion part 24 to the exterior wall tile 2. In this case, the predetermined direction may be a direction that is perpendicular to the thickness direction of the main body 10a and tilted from the lateral direction of the main body 10a.

[0051] The determination process S2 may include a waveform generation process, a spectrum acquisition process, an index value acquisition process, and a comparison process, which are executed in steps S21 to S24, respectively. However, according to the present invention, the determination process S2 is not limited to this, and may be any process that determines whether or not the exterior wall tile 2 has peeled off based on the vibration detected by the sensor 15.

[0052] In the waveform generation process S21, the processing device 17 generates waveform data indicating temporal changes in the vibrations detected by the sensor 15, based on the vibrations detected by the sensor 15. This waveform data may be data representing the relationship between elapsed time and the vibrations detected by the sensor 15. In other words, the waveform data may be data representing the displacement of the vibrations at each point in time (i.e., the signal value output from the sensor 15). Note that the displacement of the vibrations may mean displacement in the positive or negative direction from the center of the vibration.

[0053] In the waveform generation process S21, the processing device 17 may generate waveform data for a time when fluctuations occur with amplitudes greater than a predetermined value. Alternatively, the user of the mobile terminal 10 may input a waveform generation command by operating the operation unit 11, and the processing device 17 may generate the waveform data from the time the waveform generation command was input (start time) to the end time when a predetermined time has elapsed. In this case, after inputting the waveform generation command, the user taps the exterior wall tile 2 using the mobile terminal by the end time.

[0054] In the spectrum acquisition process S22, the processing device 17 converts the waveform data generated in the waveform generation process S21 into spectrum data representing the vibration intensity (frequency components) at each frequency.

[0055] In the index value acquisition process S23, the processing device 17 determines an index value relating to the presence or absence of peeling of the exterior wall tiles 2 based on the spectrum data determined in the spectrum acquisition process S22.

[0056] In one example, the index value may be the ratio of the vibration intensity at the second frequency to the vibration intensity (i.e., vibration component) at the first frequency, where the first frequency in the spectrum does not tend to increase even if peeling occurs on the exterior wall tile 2, and the second frequency may be the frequency where the vibration intensity at the second frequency tends to increase when peeling occurs on the exterior wall tile 2.

[0057] In another example, the index value may be the ratio of the vibration intensity in the second frequency band to the vibration intensity (i.e., vibration component) in the first frequency band. Here, the first frequency band may be a frequency band in the above spectrum where the vibration intensity at the first frequency tends not to increase even if peeling occurs on the exterior wall tile 2, and the second frequency band may be a frequency band where the vibration intensity at the second frequency tends to increase when peeling occurs on the exterior wall tile 2. In this case, the vibration intensity in the first frequency band may be, for example, the average value or maximum value of the vibration intensity in that frequency band, and the vibration intensity in the second frequency band may similarly be the average value or maximum value of the vibration intensity in that frequency band.

[0058] In the comparison process S24, the processing device 17 compares the index value obtained in the index value acquisition process S23 with a reference value to determine whether or not the exterior wall tile 2 is peeling. For example, if the obtained index value is greater than the reference value, the processing device 17 determines that the exterior wall tile 2 is peeling.

[0059] The reference value may be a value determined in advance, for example, through an experiment. The reference value may also be determined in advance according to the assumed type of exterior wall tile 2 and the assumed type of exterior wall surface 1.

[0060] In the notification process S3, the processing device 17 notifies the user of the mobile terminal 10 of the determination result of the determination process S2, whether or not the exterior wall tiles 2 are peeling, using the hardware elements of the mobile terminal 10. For example, the processing device 17 causes the display 12 to display the determination result, or causes the speaker 19 of the mobile terminal 10 to output a sound corresponding to the determination result.

[0061] Display processing S4 is performed when the processing device 17 determines in determination processing S2 that the exterior wall tiles 2 are peeling. In this case, in display processing S4, the processing device 17 displays information about contractors who can deal with the peeling of the exterior wall tiles 2 (for example, who can respond to inquiries about the peeling or who can repair the peeling) on ​​the display 12. This information may be, for example, the contractor's contact information (telephone number or email address), a link to the contractor's homepage, the URL of the homepage, or a submission form.

[0062] If the information about the provider is a telephone number, the mobile terminal 10 may call the telephone number displayed on the display 12 provided with a touch panel by touching the telephone number with a finger or the like.

[0063] If the information about the supplier is a link to the supplier's homepage, the homepage may be displayed on the display 12 by touching the link displayed on the display 12, which is provided with a touch panel, with a finger or the like.

[0064] If the information about the supplier is a transmission form, the inquiry content may be entered into the displayed transmission form by operating the operation unit 11 (e.g., a touch panel), and the transmission form may be sent to the supplier via the Internet.

[0065] The display process S4 may be performed simultaneously with the notification process S3, or may be performed after the notification process S3.

[0066] (Effects of the embodiment) According to this embodiment, a peeling inspection application program is stored in the storage device 16 of the mobile terminal 10, and the processing device 17 of the mobile terminal 10 determines whether or not the exterior wall tiles 2 have peeled off based on the vibrations detected by the sensor 15 when the exterior wall is tapped with the mobile terminal 10 in accordance with the peeling inspection application program. In this way, the exterior wall tiles 2 are tapped with the mobile terminal 10, and the vibrations generated at that time are processed using the sensor 15 (acceleration sensor 15a or sound sensor 15b) provided in the mobile terminal 10 and the processing device 17, thereby making it possible to determine whether or not the exterior wall tiles 2 have peeled off. Therefore, by installing the peeling inspection application program in the mobile terminal 10, even a person who has no experience in distinguishing between tapping sounds can inspect whether or not the exterior wall tiles have peeled off using a mobile terminal 10 that is not dedicated to determining whether or not the exterior wall tiles have peeled off.

[0067] Furthermore, in this embodiment, a percussion section 24 for tapping the exterior wall tile 2 is provided on the outside of the protective case 20 of the mobile terminal 10. Therefore, when tapping the exterior wall tile 2 with the mobile terminal 10, the exterior wall tile 2 can be tapped with the percussion section 24 of the case 20 to which the mobile terminal 10 is attached. This protects the main body 10a of the mobile terminal 10. That is, the case 20 not only functions as a case that protects the main body 10a from impacts when the mobile terminal 10 is accidentally dropped, but also functions as a case that protects the main body 10a when tapping.

[0068] The percussion parts 24 are provided on the outer surface of the corners of the outer periphery cover part 21. This makes it easier to percussion the exterior wall tiles 2 with the percussion parts 24 of the case 20 with the mobile phone attached inside.

[0069] When the processing device 17 determines in accordance with the peeling inspection application program that peeling has occurred in the exterior wall tiles 2, it displays on the display 12 information about a contractor that can handle the peeling of the exterior wall tiles 2. Therefore, when a person who does not have specialized knowledge about peeling or repair of the exterior wall tiles 2 confirms peeling of the exterior wall tiles 2 using the mobile terminal 10, they can quickly make an inquiry about the peeling of the exterior wall tiles 2 or request repairs from the contractor indicated by the information.

[0070] The present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the technical concept of the present invention. For example, any of the following modified examples 1 to 7 may be adopted alone, or two or more of the modified examples 1 to 7 may be adopted in any combination. In this case, the points not described below are the same as those described above.

[0071] (Change example 1) In the above description, the presence or absence of peeling of the exterior wall tile 2 is determined based on either the acceleration of the acceleration sensor 15a or the sound of the sound sensor 15b, but the presence or absence of peeling of the exterior wall tile 2 may also be determined based on both the acceleration of the acceleration sensor 15a and the sound of the sound sensor 15b. In this case, the above-described start-up process S1 and determination process S2 of the exterior wall tile peeling inspection process are performed for each of the acceleration and sound detected by the acceleration sensor 15a and the sound sensor 15b, respectively, when the exterior wall tile 2 is tapped with the mobile terminal 10. If it is determined in determination process S2 that the exterior wall tile 2 is peeling for at least one or both of the acceleration and the sound, in notification process S3, the processing device 17 may notify the user of the mobile terminal 10 of the determination result that the exterior wall tile 2 is peeling, using the hardware elements of the mobile terminal 10, and the above-described display process S4 may be performed.

[0072] (Change example 2) The case 20 may be omitted, and the exterior wall tile 2 may be directly tapped with the main body 10a of the mobile terminal 10 (for example, by tapping or rubbing).

[0073] (Change example 3) The tapping section 24 may be omitted, and the exterior wall tile 2 may be tapped with a hard object other than the mobile terminal device 100, and the sound generated thereby may be detected by the sound sensor 15b as the above-mentioned vibration, and the judgment process S2 may be performed based on the detected sound.

[0074] (Change example 4) The case 20 is not limited to the above-described configuration, and may be any configuration in which the mobile terminal 10 is attached inside and the percussion section 24 is provided on the outside.

[0075] For example, case 20 may have an openable surface cover that covers the surface of mobile terminal 10. Fig. 5A shows an example of the configuration of case 20 having surface cover 25. Fig. 5A shows a state in which surface cover 25 is open, and Fig. 5B shows a state in which surface cover 25 is closed and covers the surface of main body 10a. Fig. 5C is a cross-sectional view taken along line 5C-5C of Fig. 5A, and Fig. 5D is a cross-sectional view taken along line 5D-5D of Fig. 5B. In Figs. 5C and 5D, the dashed double-dashed line indicates main body 10a of mobile terminal 10 in the attached state.

[0076] As shown in Figures 5B and 5D, when the case 20 is attached, it has a side cover portion 26 located laterally outside the lateral outer surface of the main body 10a, and this side cover portion 26 may be provided with a percussion portion 24.

[0077] 5A to 5D, in addition to the configuration of FIG. 3A, case 20 has rear cover portion 27 coupled to rear portion 22, side cover portion 26 coupled to rear cover portion 27 so as to be bendable relative to rear cover portion 27, and front cover portion 25 coupled to side cover portion 26 so as to be bendable relative to side cover portion 26. Side cover portion 26 bends relative to rear cover portion 27, and front cover portion 25 bends relative to side cover portion 26, so that front cover portion 25 covers the front surface of main body 10a, as shown in FIGS. 5B and 5D. Although not shown, in the example of FIG. 5A, rear cover portion 27 has hole 22a for camera 14 formed at a position corresponding to hole 22a described above.

[0078] (Change example 5) In the above-described embodiment, the sensor 15 for detecting the vibrations is the acceleration sensor 15a or the sound sensor 15b, but it may be another sensor 15. For example, if the mobile terminal 10 has a piezoelectric element as a hardware element, the sensor 15 may be a piezoelectric element. This piezoelectric element may be used in the mobile terminal 10 for purposes other than the exterior wall tile peeling inspection process.

[0079] (Change example 6) The above-described case 20 may be omitted, and the percussion unit 24 may be attached to the mobile terminal 10 via an attachment means other than the case 20. This attachment means may be a clip unit that is attached to the main body 10a by clamping a part of the outer periphery of the main body 10a, and the percussion unit 24 may be coupled to this clip unit.

[0080] (Change example 7) The percussion part 24 may be a rolling member such as a roller or a spherical member. In this case, the percussion part 24 may be supported by an appropriate support member (for example, a support member provided on the case 20) so as to be able to roll about its rotation axis. In this case, percussion of the exterior wall tile 2 with the percussion part 24 may mean rolling the rolling member as the percussion part 24 on the exterior wall tile 2 while the rolling member is in contact with the exterior wall tile 2.
