[Modes for carrying out the invention]

[0008] The following describes inspection information recording systems according to several embodiments, with reference to the drawings. Note that in each embodiment, identical components may be denoted by the same reference numerals and their description may be omitted. Furthermore, in this specification, the inspection information recording system may be simply referred to as the "system."

[0009] (First Embodiment) The first embodiment will be described below with reference to Figures 1 to 6. System 1 shown in Figure 1 is a system for recording information regarding the inspection results of a product W processed by an external production facility 90. The production facility 90 is a so-called semi-automatic facility that processes a workpiece set by, for example, an operator O, and automatically inspects the product W produced by the processing. The production facility 90 is equipped with, for example, a display unit (not shown), which displays inspection information indicating the inspection results for product W. Operator O can grasp the inspection results of product W by visually confirming the inspection information displayed on the display unit. The inspection information includes, for example, the product number information of product W, information indicating whether product W is of good or bad quality, and information indicating the type of defect if product W is defective. The types of defects include, for example, dimensions, shape, appearance, etc., and can be arbitrarily set according to the attributes and condition of product W.

[0010] System 1 comprises a management device 10 and a worker terminal 20. The management device 10 and the worker terminal 20 are connected to each other so that they can communicate with one another via a network 2, which includes, for example, the internet or a telephone line. Network 2 may be configured as a LAN line, and the management device 10 and the worker terminal can be connected to each other so that they can communicate with one another via wireless LAN through, for example, an access point (not shown).

[0011] The management device 10 is configured, for example, as a server, and has the function of acquiring and aggregating information regarding the inspection results of product W, and the function of visualizing the acquired information regarding the inspection results of product W and outputting it to the worker terminal 20. The management device 10 may also be configured as an external server, such as a web server, located on the internet.

[0012] The management device 10 comprises a device control unit 101, a storage unit 11, and a communication unit 12. The device control unit 101 is responsible for the overall control of the management device 10. The device control unit 101 is mainly composed of a microcomputer, for example, a CPU (not shown). Each process of the device control unit 101 is realized by the CPU executing a program. The storage unit 11 and the communication unit 12 are electrically connected to the device control unit 101.

[0013] The storage unit 11 is configured to store various types of information that are referenced or updated by the device control unit 101 and used by the management device 10. The storage unit 11 can be made of a well-known storage medium such as an HDD, SSD, semiconductor memory, or magnetic disk. The communication unit 12 is an interface that enables communication between the management device 10 and the worker terminal 20 via the network 2.

[0014] The worker terminal 20 can be, for example, a portable information and communication terminal for worker O, such as a smartphone, tablet, or laptop computer. The worker terminal 20 can also be a wearable device, such as a head-mounted display worn on the worker's head or a smartwatch worn on the wrist. The worker terminal 20 may also be equipped with a reading unit (not shown) for reading two-dimensional codes. The worker terminal 20 comprises a terminal control unit 201, an operation display unit 21, a timing unit 22, and a communication unit 23. The terminal control unit 201 is responsible for the overall control of the worker terminal 20. The terminal control unit 201 is mainly composed of a microcomputer, such as a CPU (not shown). The operation display unit 21, the timing unit 22, and the communication unit 23 are each electrically connected to the terminal control unit 201.

[0015] The operation display unit 21 can receive inputs from the operator O and display images. In this embodiment, the operation display unit 21 is configured such that the operator O can input inspection information indicating the inspection results of the product W displayed on the display unit of the production facility 90. Further, the operation display unit 21 can display various information processed by the management device 10 such as inspection information in response to an instruction from the terminal control unit 201 and present this information to the operator O. The operation display unit 21 has an input unit 211 and a display unit 212. The input unit 211 is composed of, for example, a touch panel, a keyboard, etc., and receives the input operations of the operator O. Note that the input unit 211 may be configured to receive non-contact inputs such as voice input, gesture input, and gaze input. The display unit 212 can present information to the operator O and can display, for example, the content input-operated on the input unit 211. The input unit 211 and the display unit 212 may be configured to be overlapped with each other and arranged integrally, or may be configured to be arranged at different positions.

[0016] The timing unit 22 can be configured integrally with the operation display unit 21. The timing unit 22 has, for example, a function of acquiring the time at an arbitrary point. The time means, for example, an absolute time such as what time, what minute, and what second, or a relative time based on a certain point. The communication unit 23 is an interface that performs communication between the management device 10 and the operator terminal 20 via the network 2.

[0017] Further, the management device 10 includes an acquisition processing unit 13 and a visualization processing unit 14. The acquisition processing unit 13 and the visualization processing unit 14 are virtually realized by the CPU of the device control unit 101 executing a computer program stored in the storage unit 11. A part or all of the acquisition processing unit 13 and the visualization processing unit 14 may be configured by hardware. Note that the acquisition processing unit 13 and the visualization processing unit 14 can be configured by the same or common hardware, or can be configured by different hardware. Also, a part or all of the acquisition processing unit 13 and the visualization processing unit 14 may be provided in the operator terminal 20.

[0018] The acquisition processing unit 13 is capable of executing acquisition processing. The acquisition processing includes processing for acquiring the information input to the input unit 211. The acquisition processing includes processing for acquiring inspection information from the worker terminal 20 using the communication unit 12. The acquisition processing unit 13 stores the inspection information acquired from the worker terminal 20 in the storage unit 11 together with the acquisition time. Further, the acquisition processing includes processing for generating aggregated information obtained by aggregating the inspection information acquired from the worker terminal 20. The acquisition processing unit 13 stores the aggregated information in the storage unit 11. The aggregated information can be configured in a tabular format such as CSV format, for example. The aggregated information is not limited to the tabular format and may be in other formats such as a document format.

[0019] The visualization processing unit 14 is capable of executing visualization processing. The visualization processing includes processing for causing the display unit 212, that is, the operation display unit 21, to display an operation screen 31 for the worker O to input inspection information. Further, the visualization processing includes processing for updating the display of the operation screen 31 of the display unit 212 based on the aggregated information generated by the acquisition processing unit 13. On the operation screen 31, as shown in FIG. 2, a first area 32, a second area 33, and a third area 34 are arranged. On the operation screen 31, the first area 32 can be configured to occupy a larger range than the second area 33 and the third area 34.

[0020] The visualization processing unit 14 can change the arrangement of each of the areas 32 to 34 between a landscape screen and a portrait screen. Further, the visualization processing unit 14 can change the arrangement of each of the areas 32 to 34 between a landscape screen and a portrait screen. The landscape screen means a display screen when the display unit 212 is in a horizontal orientation, and the portrait screen means a display screen when the display unit 212 is in a vertical orientation. In the case of a landscape screen, the first area 32 is displayed, for example, on the left side of the operation screen 31. In the first area 32, an input form 321 for the worker O to input the inspection result of the product W is displayed. By displaying the input form 321 on the left side of the operation screen 31 in the landscape screen, the input form 321 is more likely to catch the eye of the worker O, improving the operability.

[0021] The first area 32 includes a specific information input field 322, a pass button 323, a defective button 324, a release button 325, and a record button 326. The specific information input field 322, the pass button 323, the defective button 324, the release button 325, and the record button 326 constitute the input unit 211. The specific information input field 322 is located, for example, near the top of the first area 32 and accepts input of specific information that identifies product W. The specific information is the product number information of product W, and is composed of a combination of numbers, letters, and symbols, and can be entered by the worker O. For example, if product W has a two-dimensional code on which the specific information is registered, the worker terminal 20 may read the two-dimensional code, thereby omitting the input of the specific information into the specific information input field 322.

[0022] The pass button 323 is located, for example, on the left side of the first area 32, in this case on the left side of the operation screen 31, and is formed in a roughly rectangular shape. The pass button 323 accepts input indicating that the inspection result of product W is pass. The pass button 323 is composed of, for example, the word "Pass".

[0023] The defective button 324 is positioned, for example, on the right side of the first area 32, in this case closer to the center of the operation screen 31, and is formed in a roughly rectangular shape. The defective button 324 accepts input indicating that the inspection result of product W is defective. Multiple defective buttons 324 are provided, as shown in Figure 2, etc. For example, six defective buttons 324 are provided, corresponding to the type of defect, and are composed of words such as "Defective A," "Defective B," "Defective C," "Defective D," "Defective E," and "Other." Instead of displaying the multiple defective buttons 324 on the operation screen 31 at all times, the system may be configured to display them when a predetermined icon composed of the word "Defective" is selected continuously for a predetermined time or longer, and input can be performed by a flick operation. This suppresses the occurrence of malfunctions such as accidental input due to touching an adjacent defective button 324, and also reduces the area occupied by the defective buttons 324 within the first area 32, thus allowing for effective use of the first area 32. In Figure 2 and other diagrams, the reference numeral for a defective button 324 is only shown in one place for clarity, and the reference numerals for the other defective buttons 324 are omitted.

[0024] In this embodiment, the operation screen 31 is configured so that only one of the buttons 323 or 324 among the pass button 323 and the multiple defective buttons 324 can be selected. In other words, the operation screen 31 is configured so that two or more defective buttons 324 cannot be selected simultaneously. For example, if "Defective A" is selected by operator O and then "Defective B" is selected, the selection of "Defective A" is deselected and the selection of "Defective B" is set. By preventing the simultaneous selection of multiple inspection results in this way, input errors are suppressed.

[0025] The defective button 324 is displayed smaller than the pass button 323. In other words, the pass button 323 is displayed larger than the defective button 324. Generally, in the inspection of product W, there are more good products than defective products. Therefore, by making the pass button 323 larger than the defective button 324, it is made easier for the operator O to press the pass button 323. Also, by displaying the defective button 324 smaller than the pass button 323, the operator O will be more careful when pressing the defective button 324, and as a result, errors in input can be suppressed.

[0026] The display formats of the pass button 323 and the fail button 324 may be the same or different. Furthermore, the display format of the pass button 323 and the fail button 324 is not limited to a roughly rectangular button configuration; they may be arranged in a ring shape circumferentially or in a linear arrangement, or they may be other display formats such as radio buttons, checkboxes, and pull-down menus. Moreover, they may be arranged in a configuration where the pass button 323 and the fail button 324 are placed on each face of a three-dimensional shape such as a polyhedron.

[0027] Furthermore, the initial screen of the operation screen 31 may be configured so that the "pass" button 323 is pre-selected from the "pass" button 323 and the "fail" button 324. This eliminates the need to select "pass," which accounts for the majority of the overall inspection results, thus improving the efficiency of the inspection result input process.

[0028] The release button 325 is positioned, for example, adjacent to the specific information input field 322. The release button 325 accepts an operation to cancel the content entered by the worker O. The release button 325 is composed of text, for example, "Deselect".

[0029] The record button 326 is located, for example, at the lower end of the first area 32, in this case the lower end of the operation screen 31, and is formed in a roughly rectangular shape. The record button 326 receives an operation from the operator O to record the input results received for the pass button 323 and the fail button 324. The operator O can perform an input operation on the record button 326 after performing an input operation on either the pass button 323 or the fail button 324. When an input operation is performed on the record button 326, inspection information is transmitted from the operator terminal 20 to the management device 10. Alternatively, the system may be configured to accept an input operation on the record button 326 by, for example, a drag-and-drop operation to move the pass button 323 or the fail button 324 to the record button 326.

[0030] Alternatively, even if the record button 326 is pressed, the inspection information is not sent to the management device 10 each time. Instead, the system may be configured so that the inspection information is sent to the management device 10 all at once by selecting a confirmation button (not shown) consisting of the word "Confirm". In this case, it may be possible to modify each piece of inspection information before it is sent all at once.

[0031] The recording button 326 may be configured to have multiple buttons, each corresponding to a pass button 323 and a fail button 324. Multiple recording buttons 326 can be placed in different positions on the operation screen 31. This prevents incorrect recording of inspection results, for example, if operator O mistakenly presses a recording button 326 that does not correspond to a pass button 323 or a fail button 324. Furthermore, the recording button 326 may be configured to only accept input when pressed simultaneously with either a pass button 323 or a fail button 324.

[0032] The position of the recording button 326 is not limited to a fixed position; it can also be configured to change. This allows the operator O to be more aware of the input operation of the recording button 326, thereby preventing errors.

[0033] The record button 326 is composed of text such as "Send". The record button 326 is positioned adjacent to the pass button 323. The horizontal size of the record button 326 can be set to be approximately the same as the horizontal size of the first area 32. By displaying the record button 326 large in the first area 32, the operator O can minimize the movement of their fingers when recording the input results, thereby improving operability.

[0034] In this embodiment, on the operation screen 31, if neither the pass button 323 nor the fail button 324 is input (i.e., selected), the background color of the pass button 323, the fail button 324, and the record button 326 is displayed as "white" or "colorless". When the pass button 323 is selected, as shown in Figure 2, the background color of the pass button 323 is displayed as "green", while when the fail button 324 is selected, as shown in Figure 3, the background color of the fail button 324 is displayed as "red". Note that in Figures 2 and 3, the background colors of buttons 323, 324, and 326 are represented by hatching. Furthermore, the system 1 can be configured so that the colors corresponding to the pass button 323 and the fail button 324 can be arbitrarily set by the operator O or the like.

[0035] The visualization processing unit 14 displays the pass button 323 and the fail button 324 in different forms when it receives input from the operator O for each of them. Furthermore, the inputted pass button 323 or fail button 324 may be displayed larger, for example, within the first area 32, compared to the other uninputted buttons 323 and 324. This allows the operator O to easily recognize the content of the selected button 323 or 324, thereby suppressing input errors. Note that the method for displaying the pass button 323 and the fail button 324 in different forms is not limited to background color; other methods such as surrounding the outlines of the buttons 323 and 324 with different types of borders or displaying the text on the buttons 323 and 324 in different colors are also possible.

[0036] The background color of the record button 326 is displayed in the same color, for example, "blue," when either the pass button 323 or the fail button 324 is selected. By changing the display color of the record button 326 when either the pass button 323 or the fail button 324 is selected, the operator O can be prompted to record the input result. The display colors of the record button 326 when either the pass button 323 or the fail button 324 is selected may be configured to be different from each other. In this case, the shape of the record button 326 may be displayed in different shapes when the pass button 323 and the fail button 324 are selected. This allows the operator O to confirm whether the pass button 323 or the fail button 324 has been selected by looking at the display of the record button 326, thereby preventing the recording of incorrect inspection results.

[0037] Furthermore, if the recording button 326 is pressed while the faulty button 324 is selected, the visualization processing unit 14 displays a pop-up 35 on the operation screen 31 to confirm whether or not there is an error in the input. As shown in Figure 4, the pop-up 35 displays text such as "Register data. Is that OK?" along with an OK button 351 and a Cancel button 352. The OK button 351 accepts the operation to record the input. The Cancel button 352 accepts the operation to cancel the recording of the input.

[0038] When the popup 35 is displayed, worker O presses the OK button 351 if they want to record the input as is, or presses the Cancel button 352 if they want to change the input, and changes the input on the operation screen 31. Displaying the popup 35 helps to suppress incorrect input by worker O. The visualization processing unit 14 may also display the popup 35 on the operation screen 31 when the record button 326 is pressed while the pass button 323 is selected.

[0039] As shown in Figure 2, the second area 33 is displayed to the right of the operation screen 31, for example, in landscape mode. In other words, the second area 33 is arranged side by side with the first area 32, for example. The size of the second area 33 is set to be slightly smaller than that of the first area 32. The second area 33 displays graph information 331, which shows the frequency of occurrence of each defect corresponding to multiple defective buttons 324 in a graph. The graph information 331 is displayed on the operation screen 31, that is, within the same screen, together with the input form 321. In other words, the visualization processing unit 14 executes a process to display two or more pieces of information on the same screen.

[0040] In this embodiment, displaying two or more pieces of information on the same screen means that both pieces of information are displayed on the same screen during the same period, that is, that both pieces of information are displayed on the same screen simultaneously. In this case, "same screen" refers to the screen of the worker terminal, i.e., the display device, that is under the control of the visualization processing unit 14, and is a concept that includes not only the screen of a single display device, but also the screens of two or more physically separated display devices. For example, a configuration that expands the display range and displays information on multiple display devices, such as a so-called dual display, can also be considered as displaying on the same screen.

[0041] Furthermore, displaying two or more pieces of information simultaneously does not require them to be strictly simultaneous; it is sufficient that the viewer perceives them as being displayed at the same time. For example, even if two or more pieces of information are displayed in short intervals, if the viewer can grasp both pieces of information simultaneously, that display method is included in the concept of simultaneous display in this embodiment.

[0042] The graph information 331 is composed of, for example, a Pareto chart. By displaying the graph information 331, when worker O is inputting, for example, a type of defect that occurs infrequently, worker O can be made aware of whether there is an error in the type of defect O is selecting. This encourages worker O to be more careful in their input operations and reduces the likelihood of input errors. Note that the graph information 331 is not limited to a Pareto chart; it may also be composed of other chart formats such as line graphs, bar graphs, and pie charts.

[0043] The third area 34 is displayed, for example, near the top of the operation screen 31. The third area 34 displays result information 341. As shown in Figure 2, the result information 341 includes production quantity information 342 indicating the number of products W produced, i.e., the total number of inspections; pass quantity information 343 indicating the number of products that passed the inspection; reject quantity information 344 indicating the number of products that failed the inspection; and defect rate information 345 indicating the ratio of the number of rejects to the total number of inspections. Based on the graph information 331 displayed in the visualized second area 33 and the result information 341 displayed in the third area 34, the worker O can consider countermeasures, such as whether or not maintenance of the production equipment 90 is necessary.

[0044] As shown in Figure 5, the visualization processing unit 14 displays the first area 32 at the bottom of the operation screen 31 and the second area 33 at the top of the operation screen in portrait mode. In other words, the first area 32 and the second area 33 are arranged side by side, one above the other. In this case, the vertical and horizontal sizes of the first area 32 and the second area 33 can be set to be approximately the same. In portrait mode, by displaying the input form 321 shown in the first area 32 at the bottom of the operation screen 31, it becomes easier for worker O to perform input operations on the operation screen 31 when the worker terminal 20 is, for example, a tablet terminal and worker O is holding the worker terminal 20 in their hand to operate it.

[0045] Next, with reference to Figure 6, an example of the control operations performed in the inspection information recording system 1 will be described. In the following description, the entity performing the control will be referred to as the device control unit 101. When the device control unit 101 starts processing, in step S11, it displays the operation screen 31 on the operation display unit 21 of the worker terminal 20. Next, in step S12, the device control unit 101 receives the input of the inspection result of product W.

[0046] In step S12, the device control unit 101 may automatically cancel the input operation of the pass button 323 or the failure button 324 if the pass button 323 or the failure button 324 is input and the record button 326 is not operated for a predetermined time. This prevents malfunctions such as the pass button 323 or the failure button 324 being input at an unintended time by the operator O, followed by an incorrect input of the record button 326.

[0047] In step S13, the device control unit 101 determines whether the inspection result of product W, input by operator O, is defective or not. If the inspection result of product W is not defective, i.e., it passes (NO in step S13), the device control unit 101 proceeds to step S17.

[0048] In step S17, the device control unit 101 acquires inspection information from the operator terminal 20 and generates and stores aggregated information. Then, in step S18, the device control unit 101 updates the contents of the graph information 331 and result information 341 on the operation screen 31 based on the aggregated information. The device control unit 101 then returns to step S12 and repeats the process from step S12 onward.

[0049] On the other hand, if the inspection result of product W entered by operator O is found to be defective (YES in step S13), the device control unit 101 proceeds to step S14. In step S14, the device control unit 101 displays a pop-up 35 on the operation screen 31. Next, in step S15, the device control unit 101 determines whether the OK button 351 of the pop-up 35 has been pressed. If the OK button 351 has been pressed (YES in step S15), the device control unit 101 proceeds to step S17.

[0050] On the other hand, if the OK button 351 is not pressed (NO in step S15), the device control unit 101 proceeds to step S16. In step S16, the device control unit 101 determines whether or not the cancel button 352 of the pop-up 35 has been pressed. If the cancel button 352 has been pressed (YES in step S16), the device control unit 101 returns to step S12. On the other hand, if the cancel button 352 is not pressed (NO in step S16), the device control unit 101 returns to step S15.

[0051] The inspection information recording system 1 according to the embodiment described above is a system for recording information regarding the inspection results of product W. The inspection information system 1 includes a visualization processing unit 14. The visualization processing unit 14 displays an operation screen 31 on the display unit 212 for the operator O to input information.

[0052] The visualization processing unit 14 displays a specific information input field 322, a pass button 323, a defective button 324, and a record button 326 on the operation screen 31. The specific information input field 322 accepts input of specific information that identifies product W. The pass button 323 accepts input that the inspection result of product W is pass. The defective button 324 accepts input that the inspection result of product W is defective. The record button 326 accepts operation to record the input results received from operator O for the pass button 323 and the defective button 324.

[0053] According to this, worker O can electronically record the inspection results of product W by inputting information into the specific information input field 322, the pass button 323, the defective button 324, and the record button 326 displayed on the display unit 212. This eliminates the need for manual recording by worker O. As a result, the inspection results of product W can be recorded efficiently.

[0054] Furthermore, the visualization processing unit 14 displays the defective button 324 smaller than the pass button 323 on the operation screen 31. As a result, the defective button 324 becomes relatively more difficult to input than the pass button 323, prompting the operator O to be more careful when inputting the defective button 324. This effectively suppresses input errors by the operator O, allowing for accurate recording of inspection results.

[0055] Furthermore, the visualization processing unit 14 places the pass button 323 and the record button 326 adjacent to each other on the operation screen 31. In the inspection of product W, there are more pass buttons (good products) than defective products. Therefore, by placing the record button 326 near the pass button 323, the operator O can minimize the movement of their fingers when recording the input results. Thus, operability is improved, and as a result, the inspection results of product W can be recorded efficiently.

[0056] Multiple defective buttons 324 are provided. The visualization processing unit 14 displays graph information 331 on the operation screen 31 along with the specific information input field 322, the pass button 323, the multiple defective buttons 324, and the record button 326. The graph information 331 shows the frequency of occurrence of each defect corresponding to the multiple defective buttons 324 in a graph.

[0057] According to this, by displaying graph information 331, when worker O is inputting, for example, a type of defect that occurs infrequently, worker O can be made aware of whether there is an error in the type of defect O is selecting. As a result, worker O's input operations become more careful, reducing input errors, and thus the inspection results can be recorded more accurately.

[0058] Alternatively, instead of the record button 326, the system may be configured to accept an operation to record the input results received from the operator O for the pass button 323 and the fail button 324 by a predetermined operation different from the input operation for the pass button 323 or the fail button 324. In this case, the acquisition process includes a process to record the input results received from the operator O for the pass button 323 and the fail button 324 when a predetermined operation different from the input operation for the pass button 323 or the fail button 324 is received. The predetermined operation includes, for example, a so-called double-tap operation which is a consecutive double-press operation, a long-press operation of the selected button 323 or 324, and a sliding operation of a predetermined amount while pressing the selected button 323 or 324. For example, when the recording of inspection results is accepted by a sliding operation for the pass button 323 and the fail button 324, the sliding direction for accepting the recording can be set to a different direction for the pass button 323 and the fail button 324. This can prevent the inspection results from being recorded incorrectly.

[0059] (Second Embodiment) Next, a second embodiment will be described with reference to Figures 7 and 8. In this second embodiment, when the acquisition processing unit 13 receives input for the pass button 323 or the fail button 324, it makes a provisional determination of the inspection result for the product being inspected this time, and also records the inspection result for the previous product being inspected when the provisional determination was made. In this case, the communication unit 12 is used to acquire the inspection result from the worker terminal 20. As a result, the worker O can efficiently record the inspection result of product W to the management device 10 by inputting to the pass button 323 and the fail button 324. In other words, the worker O can record the inspection result without inputting to the record button 326, thus improving operability. A provisional determination indicates a state in which the recording of the inspection result of product W has not been finalized, that is, a state in which it has not been stored as aggregated information, and means that the inspection result of product W is temporarily determined. In this embodiment, the provisional determination of the inspection result is the first process, and the recording of the inspection result is the second process.

[0060] As shown in Figure 7, the input form 321 displayed on the operation screen 31 includes a specific information input field 322, a pass button 323, a fail button 324, and a cancel button 325, but does not have a record button 326. By omitting the record button 326 from the operation screen 31, it becomes easier to adjust the display size and arrangement of the various information within the input form 321. This ensures greater flexibility in the layout of the operation screen 31.

[0061] In this second embodiment, the device control unit 101 executes the control content shown in Figure 8 instead of the control content shown in Figure 6. Specifically, when the device control unit 101 starts processing, in step S21, it displays the operation screen 31 on the operation display unit 21 of the worker terminal 20. Next, in step S22, the device control unit 101 receives input of the inspection result of product W. In step S23, the device control unit 101 provisionally determines the inspection result of product W based on the input operation of the worker O to the pass button 323 or the defective button 324.

[0062] Next, in step S24, the device control unit 101 determines whether or not the inspection result for the next product W has been entered. If the inspection result has been entered (YES in step S24), the device control unit 101 proceeds to step S25 and provisionally determines the inspection result for the product W for which the inspection result has now been entered. Subsequently, in step S26, the device control unit 101 obtains the inspection result for the previously entered product W, which is in a provisionally determined state, and proceeds to step S27.

[0063] In step S27, the device control unit 101 generates and stores aggregated inspection information based on the acquired inspection results. Then, in step S28, the device control unit 101 updates the contents of the graph information 331 and result information 341 on the operation screen 31 based on the aggregated information. Finally, the device control unit 101 returns to step S24 and executes the processes from step S24 onward.

[0064] On the other hand, if the operator O has not entered the inspection result for the next product W (NO in step S24), the device control unit 101 proceeds to step S29. In step S29, the device control unit 101 determines whether the release button 325 was pressed and the input of the inspection result for the previous product W was canceled.

[0065] If the release button 325 is pressed (YES in step S29), the device control unit 101 proceeds to step S30. In step S30, the device control unit 101 cancels the inspection result of the previous product W to be inspected, returns to step S22, and executes the processes from step S22 onward. In this way, the operator O can cancel the inspection result of the previous product W to be inspected by pressing the release button 325 before inputting the inspection result of the current product W to be inspected.

[0066] On the other hand, if the release button 325 is not pressed (NO in step S29), the device control unit 101 proceeds to step S31. In step S31, the device control unit 101 determines whether a predetermined time has elapsed since the provisional determination of the inspection result of product W in step S23. The predetermined time can be set to be longer than, for example, the time normally required for worker O to input the inspection result of product W.

[0067] If the predetermined time has not elapsed (NO in step S31), the device control unit 101 proceeds to step S24. On the other hand, if the predetermined time has elapsed (YES in step S31), the device control unit 101 proceeds to step S32, acquires the inspection result in the provisionally determined state, and proceeds to step S33. In other words, the device control unit 101 automatically acquires the inspection result if the predetermined time has elapsed since the inspection result was provisionally determined. This allows the inspection result to be recorded without any input operation by the worker O, for example, if there are no more products W to be inspected remaining.

[0068] In step S33, the device control unit 101 generates and stores aggregated inspection information based on the acquired inspection results. Subsequently, in step S34, the device control unit 101 updates the contents of the graph information 331 and result information 341 on the operation screen 31 based on the aggregated information, and terminates the series of controls (termination in Figure 8).

[0069] According to this second embodiment, the operator O can record the inspection results for the product W being inspected by inputting commands to the pass button 323 and the defective button 324. This eliminates the need to input commands to, for example, the record button 326 in order to record the inspection results, thus improving operability. As a result, the inspection results for product W can be recorded efficiently.
