Description

[Technical field]

[0001] The present invention relates to an entry / exit management system for inspecting and managing a work machine when the work machine is entered or exited from a warehouse. [Background technology]

[0002] In the rental industry for hydraulic excavators and other work machines, the ownership of the work machine is not transferred to the buyer as in a normal sales contract, but the contract is a "temporary rental" with a fixed term, so reliability is required from both the lessor and the lessee. In particular, if the condition of the work machine when it is rented to the customer (in other words, when the work machine is taken out of the warehouse) differs from the condition when it is returned by the customer (in other words, when the work machine is taken into the warehouse), issues arise such as the fairness of the rental fee, as well as whether the change is attributable to the lessor or the lessee, and where the responsibility lies.

[0003] For example, Patent Document 1 listed below describes a system that stores photographic data of a work machine when it is rented to a customer and when it is returned, thereby determining whether the work machine has been damaged during the rental period and appropriately managing the work machine. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] International Publication No. 2002 / 011007 Summary of the Invention [Problem to be solved by the invention]

[0005] However, although the system described in Patent Document 1 discloses a configuration for storing a huge amount of photographic data, it does not specifically disclose how to check whether or not a work machine is damaged.

[0006] In view of the above circumstances, an object of the present invention is to provide a storage / retrieval management system that can easily check whether or not a work machine is damaged when it is stored in or removed from a warehouse. [Means for solving the problem]

[0007] The inventory management system of the present invention is an inventory management system that inspects and manages a work machine when it enters or leaves the warehouse, and comprises a server device that manages information about the work machine, and a terminal that is communicatively connected to the server device, wherein the server device has a memory unit that stores inspection report information that records inspection items and maintenance items of the work machine, identifies the inspection report information based on a request from the terminal and transmits the identified inspection report information to the terminal, and the terminal displays the inspection report information identified by the server device and has a display unit that accepts input of inspection results and a photographing unit that photographs inspection points, and when there are previous inspection results for the work machine in the memory unit, the server device identifies the previous inspection results together with the inspection items and maintenance items as the inspection report information.

[0008] In the inventory management system of the present invention, when the memory section contains the results of the previous inspection of a work machine, the server device identifies the results of the previous inspection along with the inspection items and maintenance items as inspection report information and transmits it to the terminal. Therefore, by referring to the results of the previous inspection, it is possible to easily check whether or not there is any damage to the work machine when it is brought into or taken out of the warehouse. Effect of the Invention

[0009] According to the present invention, it is possible to easily check whether or not a work machine is damaged when it is brought into or taken out of the warehouse. [Brief description of the drawings]

[0011] Hereinafter, an embodiment of an entry / exit management system according to the present invention will be described with reference to the drawings. The entry / exit management system according to the present invention is a system applied to rental services and sharing services for work machines such as hydraulic excavators, and inspects and manages the work machines when they are rented out to customers (when leaving the warehouse) and when they are returned (when entering the warehouse). Here, an example of applying the entry / exit management system to a work machine rental service will be described.

[0012] In addition, in the following description, an "inspection report" refers to a report created on a terminal in which inspection results have not been input, and an "inspection completion report" refers to a report in which inspection results have been input.

[0013] Fig. 1 is a schematic configuration diagram showing an incoming / outgoing management system according to an embodiment, and Fig. 2 is a functional block diagram showing an incoming / outgoing management system according to an embodiment. As shown in Fig. 1 and Fig. 2, an incoming / outgoing management system 1 of this embodiment includes a plurality of work machines 10 to be rented, a server device 20 that manages information on the plurality of work machines 10, and a terminal 30 used by an inspector who performs inspection work when the work machines 10 are brought into or taken out of the warehouse. The work machines 10, the server device 20, and the terminal 30 are configured to be able to communicate with each other via a network 40.

[0014] In this embodiment, a hydraulic excavator will be described as an example of the work machine 10, however, the work machine 10 is not limited to a hydraulic excavator and may be a crane truck, a wheel loader, a forklift, a bulldozer, etc., or a combination of these.

[0015] As shown in Fig. 2, the work machine 10 has a communication unit 11, a vehicle body controller 12, and an on-board sensor 13. The communication unit 11 is, for example, a wireless device for connecting to a network 40, and periodically (for example, once a day) transmits operation information of the work machine 10, including each piece of data detected by the on-board sensor 13 in accordance with commands from the vehicle body controller 12, to the server device 20. The operation information includes, for example, information such as the operation position, number of operating days, and operation time of the work machine 10. The communication unit 11 also transmits maintenance information of the work machine 10 to the server device 20. When operation information and maintenance information of the work machine 10 are transmitted to the server device 20, individual identification information of the work machine 10 (for example, a vehicle body ID) is also transmitted together.

[0016] The vehicle body controller 12 is configured by a microcomputer that combines, for example, a CPU (Central Processing Unit) that executes calculations, a ROM (Read Only Memory) as a secondary storage device that records programs for the calculations, and a RAM (Random Access Memory) as a temporary storage device that saves the calculation process and temporary control variables, and controls the entire work machine 10 by executing the stored programs.

[0017] The on-vehicle sensors 13 are various sensors attached to the work machine 10, which detect various data related to the operation of the work machine 10 and output the detected data to the vehicle body controller 12. Examples of the on-vehicle sensors 13 include a GPS (Global Positioning System) sensor that detects position information of the work machine 10, an IMU (Inertial Measurement Unit) that detects the inclination of the arm, boom and bucket of the work machine 10, a rotation angle sensor that detects the rotation angle of the rotating body of the work machine 10, and a travel operation sensor that detects travel operations.

[0018] The server device 20 is installed, for example, in the head office, branch office, factory or management center of the manufacturer of the work machine 10, and periodically collects information such as operation information transmitted from the work machine 10, and performs centralized management of the work machine 10. The server device 20 is configured by a microcomputer that combines, for example, a CPU (Central Processing Unit) that executes calculations, a ROM (Read Only Memory) as a secondary storage device that stores programs for the calculations, and a RAM (Random Access Memory) as a temporary storage device that saves the calculation progress and temporary control variables, and performs various processes by executing the stored programs.

[0019] The server device 20 has a communication unit 21, a vehicle body information management unit 22, an inspection report identification unit 23, and a memory unit 24. The communication unit 21 is, for example, a wireless device for connecting to a network 40. The vehicle body information management unit 22 manages information transmitted from the work machine 10, such as individual identification information (vehicle body ID), operation information, maintenance information, etc. of the work machine. The inspection report identification unit 23 transmits inspection report information relating to a specific work machine 10 to the terminal 30 in response to a request from the terminal 30. The inspection report information records inspection items, maintenance items, etc. of the work machine 10.

[0020] The memory unit 24 stores operation information, maintenance information, and the like of the work machine 10 transmitted from the work machine 10 together with the individual identification information of the work machine 10. The memory unit 24 also stores an inspection report format and the inspection results of the work machine 10 transmitted from the terminal 30 (i.e., the inspection completion report). And, when photographic data is included in the inspection results of the work machine 10 transmitted from the terminal 30, the memory unit 24 also stores the photographic data.

[0021] The terminal 30 is used by an inspector when performing inspection work on the work machine 10, and is, for example, a PC (Personal Computer), a tablet terminal, a smartphone, a mobile phone, etc. Here, an example of the terminal 30 will be described as a smartphone that is easy for an inspector to carry around.

[0022] For example, application software for inspecting the work machine 10 entering and leaving the warehouse is installed on the terminal 30. When inspecting a specific work machine 10 for entering and leaving the warehouse, the inspector starts up this application software and requests the server device 20 to send inspection report information on the specific work machine 10. When the server device 20 transmits the inspection report information to the terminal 30, it is displayed in a report format on the terminal 30. The inspector can perform the inspection work according to the items described in the inspection report displayed in the report format on the terminal 30, photograph the inspection points, attach the photographs to the inspection report, and input the inspection results to the inspection report, thereby creating an inspection completion report. Furthermore, the inspector can transmit the inspection completion report to the server device 20. Therefore, the terminal 30 of this embodiment has a communication unit 31, a display unit 32, a photographing unit 33, and an output unit 34.

[0023] The communication unit 31 is, for example, a radio for connecting to the network 40. The display unit 32 is, for example, a display, and has a function of displaying the contents of the inspection report, a guidance screen regarding the inspection work, and various information for the inspector. The display unit 32 also has a function of accepting input of the inspection results, input of search conditions, etc. For example, the inspector can input the inspection results, etc. by pressing or selecting an icon or button displayed on the display unit 32, or by inputting via a keyboard displayed on the display unit 32. The photographing unit 33 is, for example, a camera built into the terminal 30. The output unit 34 outputs an inspection completion report, etc.

[0024] The control processing of the warehousing / returning management system 1 will be described below with reference to Fig. 3. Here, the inspection processing at the time of entering (returning) the work machine 10 will be described as an example, but since the inspection processing at the time of leaving (renting) the work machine 10 is the same as the inspection processing at the time of entering, the description of the inspection processing at the time of leaving will be omitted.

[0025] In step S101, the work machine 10 to be inspected is identified. The methods for identifying the inspection target are mainly a method of searching for and identifying the work machine 10 in the vicinity of the terminal 30, a method of identifying by inputting conditions into the terminal 30, and a method of identifying by reading a QR code (registered trademark) affixed to the work machine 10 with the terminal 30. Each method will be described in detail below.

[0026] In the method of searching for and identifying work machines 10 in the vicinity of the terminal 30, the work machine 10 to be inspected must be configured to be able to communicate with the terminal 30 and must be present within an area capable of communicating with the terminal 30. If there are multiple work machines 10 in the vicinity of the terminal 30, the work machine 10 to be inspected is automatically displayed on the display unit 32 of the terminal 30 as an inspection target candidate (also called a list of inspection target candidates) together with the other work machines 10.

[0027] More specifically, when a work machine 10 enters an area in which it can communicate with the terminal 30, its communication unit 11 automatically becomes capable of communicating with the terminal 30 via the network 40, and the work machine 10 is automatically displayed on the display unit 32 of the terminal 30 as a candidate for inspection. At that time, what is displayed on the display unit 32 is the unique individual identification information (e.g., vehicle body ID) of each work machine 10. An inspector specifies the work machine 10 to be inspected by selecting a vehicle body ID displayed in the list of candidates for inspection.

[0028] Then, when there are multiple work machines 10 within the communication area, these work machines 10 are displayed on the display unit 32 as candidates for inspection in order of proximity to the current location of the inspector holding the terminal 30. In this way, the inspector can easily identify the work machine 10 to be inspected, and can also grasp the general location of the work machine 10. The display can be set arbitrarily, such as in order of the inspection report update date.

[0029] It is preferable that the terminal 30 has a function that can set in stages the communicable area centered on the terminal 30, and can select a communication area with a radius of, for example, 3 km, 5 km, 10 km, etc. from the current location of the terminal 30. In this way, the inspector can more easily specify the work machine 10 to be inspected from a number of candidates for inspection.

[0030] On the other hand, if the work machine 10 to be inspected is configured to be able to communicate with the terminal 30 but is not located within an area capable of communicating with the terminal 30, or if the work machine 10 is not configured to be able to communicate with the terminal 30, the inspector reads out a list of candidates for inspection that is pre-stored in the terminal 30, and selects and identifies the work machine 10 to be inspected from the read list of candidates for inspection.

[0031] The list of inspection target candidates may be stored in the server device 20 rather than in the terminal 30, and may be acquired from the server device 20. In this case, the inspector transmits position information of his / her terminal 30 to the server device 20, and the server device 20 creates a list of inspection target candidates containing the models and vehicle body IDs of the work machines 10 that exist within a predetermined range centered on the transmitted position information, and transmits this list to the terminal 30. In this way, the list of inspection target candidates can be acquired from the server device 20.

[0032] In the method of identification by inputting conditions into the terminal 30, the inspector inputs conditions such as the model name and vehicle body ID into the display unit 32 of the terminal 30 and searches to identify the work machine 10 to be inspected. In this case, in order to reduce the input work of the inspector, it is preferable that the terminal 30 is provided with a suggestion function that narrows down and offers candidates when the first number of the vehicle body ID is input, for example.

[0033] On the other hand, in the method of reading a QR code with the terminal 30, for example, when the work machine 10 to be inspected is located near the inspector, the inspector identifies the work machine 10 to be inspected by reading the QR code affixed to the work machine 10 with the code reader of the terminal 30.

[0034] When the work machine 10 to be inspected is identified in step S101, the vehicle body ID of the identified work machine 10 is automatically transmitted to the server device 20.

[0035] In step S102 following step S101, the inspection report information is specified. At this time, the inspection report specification unit 23 of the server device 20 refers to the storage unit 24 to specify the inspection report information of the work machine 10 corresponding to the transmitted vehicle body ID. Although details will be described later, the inspection report information records inspection items and maintenance items related to the work machine 10. Furthermore, at this time, if the previous inspection result (for example, the previous inspection completion report) of the work machine 10 corresponding to the transmitted vehicle body ID is stored in the storage unit 24, the previous inspection result is also specified as the inspection report information. In this embodiment, "specify" means to select information to be transmitted to the terminal 30. Furthermore, if the previous inspection result includes image data showing a photograph of the inspection location, the inspection report specification unit 23 also specifies the photograph as the inspection report information. When the inspection report information is specified, the server device 20 transmits the specified inspection report information to the terminal 30.

[0036] The inspection report information transmitted to the terminal 30 is then displayed on the display unit 32 of the terminal 30. FIG. 4 is a diagram showing an example of inspection items in an inspection report displayed in report format on the display unit of the terminal. As shown in FIG. 4, the inspection report lists inspection items such as "monitor function operation status," "operation status (front, driving, turning, etc.)," ​​and "fuel and urea water status." In addition, the inspection report displays a camera icon 341 for each inspection item. Pressing this icon 341 activates the photographing unit 33 and switches to a mode in which photographs can be taken.

[0037] The inspection report also displays a "pass" or "fail" button indicating the inspection result for each inspection item. "Pass" indicates that there are no problems with the inspection result, and "fail" indicates that some action is required or that some action has been taken. After performing each inspection task according to the inspection items listed in the inspection report, the inspector simply selects the "pass" or "fail" button to input the inspection result. When either "pass" or "fail" is selected, the color of the selected button is set to change. For example, when either "pass" or "fail" is selected, the color of the selected button turns red. This has the effect of preventing erroneous input of inspection results.

[0038] As shown in FIG. 4, each inspection item has a bar 343 displayed to indicate the result of the previous inspection. For example, in the inspection item "operation status of monitor function," a bar 343 is displayed above "passed," but not above "failed." This indicates that the result of the previous inspection of "operation status of monitor function" was "passed (no problems)." On the other hand, "failed" indicates that some kind of problem existed. It is preferable that the bar 343 be displayed in red. In this way, the inspector can easily understand the result of the previous inspection.

[0039] FIG. 5 is a diagram showing an example of maintenance items in an inspection report displayed on the display unit of a terminal. As shown in FIG. 5, the inspection report lists maintenance items such as "Engine Oil (Slewing Travel Pump)", "Engine Oil Filter", "Fuel Element", etc. Maintenance items indicate the details of the inspection results, and are listed, for example, after the inspection item in the inspection report. Buttons "Result", "Cleaning", "Refill", and "Replace" are displayed for each maintenance item. "Result" indicates that the inspection result is OK, and "Cleaning", "Refill", and "Replace" indicate that cleaning work, refill work, and replacement work have been performed, respectively. Here, when either "Cleaning", "Refill", or "Replace" is selected, "Result" cannot be selected, and similarly, when "Result" is selected, "Cleaning", "Refill", and "Replace" cannot be selected. In addition, a bar 345 indicating the previous inspection result is displayed for the maintenance items, just like the inspection items.

[0040] In step S103 following step S102, it is determined whether or not the inspection report displayed on the display unit 32 has "Last Details". Specifically, for example, a "Last Details" button 344 is displayed to the right of the inspection item "Monitor Function Operation Status" shown in FIG. 4. This "Last Details" indicates that there is photo data from the previous inspection. For example, if photo data indicating the "Monitor Function Operation Status" is attached to the previous inspection completion report, the "Last Details" button 344 is displayed for the inspection item "Monitor Function Operation Status". On the other hand, the "Last Details" button 344 is not displayed for the inspection items "Operation Status (Front / Driving / Turning, etc.)" and "Fuel / Urea Water Status". This means that photo data indicating these inspection items is not attached to the previous inspection completion report.

[0041] If it is determined in step S103 that all inspection items do not have "previous details" (No), the control process proceeds to step S106. On the other hand, if at least one inspection item has "previous details" (Yes), it is determined that there is "previous details," and the control process proceeds to step S104.

[0042] In step S104, it is determined whether or not the inspector wishes to see "previous details." If the inspector wishes to see "previous details" and presses "previous details" button 344, photos from the previous inspection are displayed (step S105). In other words, "previous details" is a link to information about the results of the previous inspection, and pressing this button switches to a screen that displays photos taken during the previous inspection. In this way, the results of the previous inspection can be referred to, and the contents to be inspected can be easily compared with the results of the previous inspection.

[0043] On the other hand, if the inspector does not wish to refer to the "Previous Details", for example by pressing a "No" button (not shown), or if no action is taken for a predetermined period of time (for example, 10 seconds), it is determined that the inspector does not wish to refer to the "Previous Details", and the control process proceeds to step S106.

[0044] In step S106, the inspector inputs the inspection results into the inspection items and maintenance items displayed on the display unit 32. At this time, the inspector inputs the inspection results by selecting the above-mentioned "pass" or "fail" button, or by selecting either "result," "clean," "replenish," or "replace."

[0045] In step S107 following step S106, it is determined whether or not the inspector desires to photograph. At this time, if the inspector desires to photograph (Yes), the inspector presses camera icon 341 shown in Fig. 4. When camera icon 341 is pressed, the control process proceeds to step S108, and the inspector can use the photographing unit 33 to photograph the inspection point.

[0046] When a photo is taken, a thumbnail image 342 is displayed next to a camera icon 341. As shown in FIG. 4, for the inspection item "operating status (front, running, turning, etc.)", one thumbnail image 342 is displayed, and a number (here, 3) is displayed at the bottom right of the thumbnail image 342. This number indicates the number of selected photos. For example, if an inspector selects three photos for the inspection item, the first photo is displayed as thumbnail image 342, and a number indicating that the total number of selected photos is three is also displayed at the bottom right of thumbnail image 342. This makes it easy to know how many photos have been selected as photo data related to the inspection.

[0047] On the other hand, if photographing is not desired in step S107 (No), for example if the inspector presses a button (not shown) indicating "I do not wish to photograph," or if no action is taken after a predetermined period of time (e.g., 10 seconds) has elapsed, it is determined that photographing is not desired, and the control process proceeds to step S113.

[0048] Here, an example of the inspection input screen and the photo library will be described with reference to FIG. 6A and FIG. 6B. FIG. 6A shows the inspection input screen displayed on the display unit 32. As shown in FIG. 6A, the inspection input screen displayed on the display unit 32 has a photo display area 351, a shooting instruction receiving area 352, and a comment receiving area 353. The photo display area 351 corresponds to the "first display area" described in the claims, and is an area for displaying a photo of the inspection location. In addition, this photo display area 351 is linked to the photo library (see FIG. 6B) in the terminal 30. As shown in FIG. 6B, the photo library stores photos of the inspection location taken by the photographing unit 33. In addition, in this case, when a photo stored in the photo library is selected, the selected photo can be displayed in the photo display area 351.

[0049] The photographing instruction receiving area 352 is an area for receiving photographing instructions. When a photographing instruction is received via the photographing instruction receiving area 352, the photograph displayed in the photograph display area 351 at that time is determined as photographic data to be attached to the inspection completion report. Note that the "report" in FIG. 6A refers to the inspection completion report.

[0050] The comment receiving area 353 corresponds to the "second display area" recited in the claims, and receives comments input by the inspector as related information of the inspection result. The comments may be configured to be selected from among prepared comment types, for example, or may be configured to be input directly by the inspector. Comment input is performed using a text input function provided in the terminal 30. The comment types are stored in the terminal 30 in advance, for example. Also, comment input may be a combination of selection from the comment types and direct input.

[0051] In step S109 following step S108, it is determined whether or not a new photograph is desired. At this time, for example, if further photographing is required (Yes), the inspector presses the "New Photograph Request" button. This causes the control process to return to step S108, and photographing is repeated. In other words, multiple photographs may be taken, and the photographs are stored in the above-mentioned photo library.

[0052] On the other hand, if new photography is not desired in step S109 (No), for example if the inspector presses a "no new photography desired" button (not shown) or if no action is taken after a predetermined time (for example, 10 seconds) has elapsed, it is determined that new photography is not desired, and the control process proceeds to step S110.

[0053] In step S110, a photo is designated (also called a photo selection). At this time, the inspector can designate photo data for each inspection item by selecting a photo to be attached to the inspection completion report from the above-mentioned photo library. In this case, if multiple photo data are to be attached, the photos can be selected consecutively. The designated photo is surrounded by a frame so that it can be distinguished from other undesignated photos. Of the photos selected here, the first one is displayed as thumbnail image 342 shown in FIG. 4 above, and the number of selected photos can be ascertained from the number at the bottom right of thumbnail image 342. In addition, if the designation is to be cancelled, the designated photo can be designated again, and the frame will disappear, indicating that it has not been designated.

[0054] In step S111 following step S110, it is determined whether the photo designated in step S110 is to be used in the inspection completion report. At this time, as shown in FIG. 6B, an arrow icon 354 is displayed in the lower right of the area displaying the photo library. When this icon 354 is pressed, the selected photo is confirmed. If the inspector wants to use the photo designated in step S110 in the inspection completion report, he or she selects icon 354, and the control process proceeds to step S113. On the other hand, if the inspector does not want to use the photo designated in step S110, he or she cancels the designation in the above procedure or returns to the previous screen without pressing icon 354, and the control process proceeds to step S112.

[0055] In step S112, it is determined whether or not to use other photos. At this time, for example, buttons (not shown) indicating "Use other photos" and "Do not use other photos" are displayed on the display unit 32. If the inspector selects "Use other photos", the control process returns to step S110. On the other hand, if the inspector selects "Do not use other photos", the control process proceeds to step S113.

[0056] In step S113, an inspection completion report is created. At this time, the terminal 30 creates the inspection completion report using the inspection results input in step S106 and the photos specified in step S110. If it is determined in the above-mentioned step S107 that "photography is not desired," the terminal 30 creates an inspection completion report without attached photos using the inspection results input in step S106.

[0057] In step S114 following step S113, the terminal 30 transmits the inspection completion report created in step S113 to the server device 20. At that time, if photo data is attached to the inspection completion report, the attached photo data is also transmitted. Upon receiving the transmitted inspection completion report, the server device 20 stores these in the storage unit 24 as inspection report information.

[0058] When step S114 is completed, the series of control processes ends.

[0059] In the storage / return management system 1 according to this embodiment, when there are previous inspection results for the work machine 10, the inspection report identification unit 23 of the server device 20 identifies the previous inspection results together with the inspection items and maintenance items as inspection report information and transmits them to the terminal 30, so that an inspector can easily check whether or not there is damage to the work machine 10 at the time of storage / return by referring to the previous inspection results. In particular, when the previous inspection results include a photograph of the location inspected last time, the presence or absence of damage to the work machine 10 can be easily confirmed by comparing the previous photograph with the current photograph.

[0060] The inspection completion report may be displayed on the display unit 32 of the terminal 30, and may also be output on paper by the output unit 34. The paper output is preferably printed with the previous inspection results and the current inspection results side by side (in other words, written side by side). In this case, it is more preferable to print a photograph relating to the previous inspection result and a photograph relating to the current inspection result side by side for each inspection item. In this way, changes in the work machine 10 when entering or leaving the warehouse can be easily visually confirmed.

[0061] Furthermore, it is preferable that the output format of the inspection completion report be different for the lender (e.g., a rental company) and the borrower (e.g., a customer) of the work machine 10. This is because the information that the lender and the borrower obtain from the inspection completion report is different. In other words, the lender needs to understand the details of the work machine 10 to be rented. This is because, in the event that a part needs to be replaced as a result of the rental and a bill for the cost of the part replacement is billed, the borrower will want to understand the condition of the part before renting and the condition of the part at the time of return, as the basis for the bill.

[0062] The output inspection completion report will be described below with reference to Figures 7 to 9. Figures 7 and 8 are inspection completion reports output to the lender, and Figure 9 is an inspection completion report output to the borrower. Also, in Figures 7 to 9, photos of the inspected areas are omitted, and instead, "photos without damage" or "photos with scratches / dents" are shown.

[0063] The inspection completion report shown in Fig. 7 is an output of the inspection results for all inspection items at the time of entry and exit. In this case, the lender of the work machine 10 can grasp the inspection results for all inspection items via the output inspection completion report. In contrast, the inspection completion report shown in Fig. 8 is an output of only the inspection items for which the inspection result at the time of entry is "no", for example. In this case, the lender of the work machine 10 can grasp only the inspection items that require repair via the output inspection completion report.

[0064] On the other hand, the inspection completion report shown in Fig. 9 outputs only the information necessary in the event that additional charges are incurred for the customer due to the replacement of parts, etc. For example, if a counterweight was undamaged when it was taken out of the warehouse, but had scratches and dents when it was brought in, the customer can see at a glance the cause of the charge by looking at the inspection completion report that lists this information.

[0065] Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various design modifications can be made without departing from the spirit of the present invention as described in the claims.
