The sheet information to be memorized (added) is associated with each of the multiple layer information (first layer, second layer, third layer, etc.). In this embodiment, the configuration of the layer correspondence table T2 is the same as the configuration of the layer correspondence table T1 stored in the drawing management device 10, but it may have a different configuration. Furthermore, the layer correspondence table T2 may store only a portion of the contents of the layer correspondence table T1 (e.g., only the content related to itself), and the link between the layer information and the sheet information in the layer correspondence table T2 may be managed independently by the terminal device 20 in a manner different from that of the layer correspondence table T1. In this embodiment, the following three operations, "Part 1" to "Part 3," are described as examples.

The CPU 21 adds a note (adds a note) to a sheet selected by the user based on an instruction from the user who uses the terminal device 20 .
When synchronizing a sheet with notes (added), the CPU 21 outputs to the drawing management device 10 via the communication unit 25 drawing identification information for identifying the sheet (including the sheet information and layer information on the sheet) and the drawing displayed on the terminal device 20. Furthermore, the CPU 21 inputs via the communication unit 25 drawing identification information for identifying a sheet (with notes (added)) (including the sheet information and layer information on the sheet) newly uploaded by another terminal device 20 and the drawing linked to the sheet.

Furthermore, when generating a display image, the CPU 21 displays only sheets for which the "Sheet Selection Display (ON/OFF)" is set to "ON" on the display unit 24, superimposed on the drawing, in response to an instruction from the input unit 23. In other words, if the user has a memo that he or she wants to display together, the CPU 21 sets the "Sheet Selection Display (ON/OFF)" of the sheet corresponding to the memo to "ON."
Here, the CPU 21 refers to the layer correspondence table T2 and generates a display image based on the association between each layer and each sheet.

An example of the display screen is shown in Figure 7. The display screen shown in Figure 7 corresponds to the contents of Figure 4. Figure 7(a) is an example of the screen when the display of sheets "a", "b", and "c" is turned "ON". Figure 7(b) is an example of the screen when the display of sheets "a" and "b" is turned "ON" and the display of sheet "c" is turned "OFF".

Notes added to sheets with the display "ON" are displayed on the display screen, while notes added to sheets with the display "OFF" are not displayed on the display screen. For example, the display switch for sheet "a" is turned "ON," the display switch for sheet "b" is turned "ON," and the display switch for sheet "c" is turned "ON." The display switches here are controls that switch the sheet display "ON/OFF" and are displayed, for example, on the screen. As a result, the notes on sheets "a," "b," and "c" are displayed superimposed on drawing A (see Figure 7(a)). Here, for example, if the display switch for sheet "a" is turned "ON," the display switch for sheet "b" is turned "ON," and the display switch for sheet "c" is turned "OFF," the notes on sheets "a" and "b" are displayed superimposed on drawing A on the screen (see Figure 7(b)).

The flow (overall flow) of using sheets divided by work items (operation_1) is shown in Fig. 9. The overall flow shown here is an example.
<Processing Step: S1>
[Processing on the terminal device 20 (tablet terminal or PC)]
The CPU 21 displays the specified drawing based on an instruction from a user of the terminal device 20. When displaying the drawing, the CPU 21 transmits a request for the drawing to the drawing management device 10 via the communication unit 25, and inputs the drawing (here, drawing A) and drawing identification information for identifying the drawing from the drawing management device 10.

[Processing on the drawing management apparatus 10 (cloud server)]
Based on an instruction from the terminal device 20 , the CPU 11 outputs the specified drawing (here, drawing A) to the terminal device 20 via the communication unit 15 .

<Processing Step: S2>
[Processing on the terminal device 20 (tablet terminal or PC)]
The CPU 21 generates sheets for the drawings to be displayed and used in the operation of the terminal device 20 based on instructions from the user of the terminal device 20. In this example, since "Operation 1" is assumed, the CPU 21 generates, for example, sheets "a", "b", and "c" for drawing A.
Here, in a newly generated sheet to be used for notes (additions), if sheet "b" is generated on terminal device 20 (e.g., terminal device 20 of Mr. β) instead of on terminal device 20 (e.g., terminal device 20 of Mr. α), and sheet "c" is not generated on terminal device 20 (e.g., terminal device 20 of Mr. α), an example of the processing of the CPU 21 in each terminal device 20 is as follows.
The CPU 21 of the terminal device 20 (for example, Mr. Alpha's terminal device 20) generates a sheet for the drawing to be displayed, which is used in the operation of the terminal device 20, in the layer correspondence table T2 of the memory unit 26, based on instructions from the user using the terminal device 20 (for example, sheet "a" for drawing A).
The CPU 21 of the terminal device 20 (for example, Mr. β's terminal device 20) generates a sheet for the drawing to be displayed, which is used in the operation of the terminal device 20, in the layer correspondence table T2 of the memory unit 26, based on instructions from the user using the terminal device 20 (for example, sheet "b" for drawing A).

[Processing on the drawing management apparatus 10 (cloud server)]
The processing on the side of the drawing management device 10 (cloud server) in processing step S2 is "none".

<Processing Step: S3>
[Processing on the terminal device 20 (tablet terminal or PC)]
When synchronizing (uploading) a newly generated sheet to be used for memos (additions), the CPU 21 of the terminal device 20 (e.g., user α's terminal device 20) associates drawing identification information for identifying the drawing (drawing A) to be displayed with the generated sheet (including sheet information and layer information (first layer, second layer, and third layer) for the generated sheets "a,""b," and "c") and outputs the associated information to the drawing management device 10 via the communication unit 25. When synchronizing (uploading) a sheet, the CPU 21 of the terminal device 20 (e.g., user α's terminal device 20) updates the layer correspondence table T2 in the storage unit 26 based on the drawing identification information for identifying the drawing (drawing A) and the generated sheet (including sheet information and layer information (first layer, second layer, and third layer) for the generated sheets "a,""b," and "c"). (Here, this processing by the CPU 21 is processing on the terminal device 20 side related to uploading (uploading related to the newly generated sheet) to the drawing management device 10 (cloud server).)
Furthermore, the CPU 21 of a terminal device 20 (e.g., Person β's terminal device 20) inputs (downloads) a sheet (including sheet information and layer information (first layer, second layer, and third layer) for sheets "a,""b," and "c") newly uploaded from another terminal device 20 (e.g., Person α's terminal device 20) from the drawing management apparatus 10 via the communication unit 25. When synchronizing a newly generated sheet, the CPU 21 updates the layer correspondence table T2 in the storage unit 26 based on drawing identification information for identifying the drawing to be displayed (drawing A) and the sheet (sheets "a,""b," and "c" and layer information) (here, this processing by the CPU 21 is processing on the terminal device 20 side related to downloading (downloading related to the newly generated sheet) from the drawing management apparatus 10 (cloud server)).
When synchronizing (downloading) sheets, the CPU 21 of the terminal device 20 (for example, Mr. β's terminal device 20) updates the layer correspondence table T2 in the memory unit 26 based on the drawing identification information for identifying the drawing (drawing A) and the sheets (including sheet information and layer information (first layer, second layer, third layer) for sheets "a", "b", and "c").
Here, in a newly generated sheet to be used for notes (additions), if sheet "b" is generated on terminal device 20 (e.g., terminal device 20 of Mr. β) instead of on terminal device 20 (e.g., terminal device 20 of Mr. α), and sheet "c" is not generated on terminal device 20 (e.g., terminal device 20 of Mr. α), an example of the processing of CPU 21 in each terminal device 20 is as follows.
When synchronizing (uploading) a sheet (sheet "a"), the CPU 21 of the terminal device 20 (for example, Mr. Alpha's terminal device 20) updates the layer correspondence table T2 in the memory unit 26 based on the drawing identification information for identifying the drawing (drawing A) and the generated sheet (including the sheet information and layer information (first layer) in the generated sheet "a").
When synchronizing (downloading) a sheet (sheet "a"), the CPU 21 of the terminal device 20 (for example, Mr. β's terminal device 20) updates the layer correspondence table T2 in the memory unit 26 based on the drawing identification information for identifying the drawing (drawing A) and the sheet (including the sheet information and layer information (first layer) in sheet "a").
When synchronizing (uploading) a sheet (sheet "b"), the CPU 21 of the terminal device 20 (for example, Mr. β's terminal device 20) updates the layer correspondence table T2 in the memory unit 26 based on the drawing identification information for identifying the drawing (drawing A) and the generated sheet (including the sheet information and layer information (second layer) in the generated sheet "b").
When synchronizing (downloading) a sheet (sheet "b"), the CPU 21 of the terminal device 20 (for example, Mr. Alpha's terminal device 20) updates the layer correspondence table T2 in the memory unit 26 based on the drawing identification information for identifying the drawing (drawing A) and the sheet (including the sheet information and layer information (second layer) in sheet "b").

[Processing on the drawing management apparatus 10 (cloud server)]
When synchronizing a sheet that is generated on the terminal device 20 (e.g., the terminal device 20 of user α) and is newly generated to be used for memos (additions), the CPU 11 inputs drawing identification information for identifying the drawing (drawing A) displayed on the terminal device 20 and the sheet (including sheet information and layer information (first layer, second layer, third layer) for sheets "a", "b", and "c") from the terminal device 20 (e.g., the terminal device 20 of user α) via the communication unit 15. Here, since "Operation 1" is assumed, the CPU 11 links, for example, the drawing (drawing A) with sheets "a", "b", and "c", and creates (stores) them in the drawing storage device 17. The CPU 11 updates the layer correspondence table T1 in the memory unit 16 based on the drawing identification information for identifying the drawing (drawing A) displayed on the terminal device 20 and the sheet (including sheet information and layer information (first layer, second layer, third layer) for sheets "a", "b", and "c"). (Here, this processing by the CPU 11 is processing on the drawing management device 10 (cloud server) side related to the upload (newly generated sheet) of the terminal device 20.)
In addition, the CPU 11 outputs to another terminal device 20 (for example, Mr. β's terminal device 20) via the communication unit 15 the newly uploaded sheets (including sheet information and layer information (first layer, second layer, third layer) for sheets "a", "b", and "c") and drawing identification information for identifying the drawing linked to the sheets (drawing A displayed on the terminal device 20) (here, this processing by the CPU 11 is processing on the drawing management device 10 (cloud server) side related to the download (newly generated sheet) of the terminal device 20).
Here, in the case of newly generated sheets to be used for notes (additions), if sheet "b" is generated on terminal device 20 (e.g., Mr. β's terminal device 20) instead of on terminal device 20 (e.g., Mr. α's terminal device 20), and sheet "c" is not generated on terminal device 20 (e.g., Mr. α's terminal device 20), an example of the processing of CPU 11 in drawing management device 10 is as follows.
When synchronizing (uploading) a newly created sheet that is generated on a terminal device 20 (for example, Mr. Alpha's terminal device 20) and is to be used for notes (additions), the CPU 11 inputs drawing identification information for identifying the drawing (drawing A) displayed on the terminal device 20 and the sheet (including sheet information and layer information (first layer) in sheet "a") from the terminal device 20 (for example, Mr. Alpha's terminal device 20) via the communication unit 15.
The CPU 11, for example, links a drawing (drawing A) to sheet "a" and creates (stores) it in the drawing memory device 17 (here, the CPU 11 may, for example, link the drawing identification information to the drawing (drawing A), and also link the drawing identification information to sheet "a" and create (store) it in the drawing memory device 17).
The CPU 11 updates the layer correspondence table T1 in the memory unit 16 based on the drawing identification information for identifying the drawing (drawing A) displayed on the terminal device 20 and the sheet (including sheet information and layer information (first layer) on the "a" sheet).
The CPU 11 outputs to the other terminal device 20 (for example, Mr. β's terminal device 20) via the communication unit 15 the newly uploaded sheet (including sheet information and layer information (first layer) in the "a" sheet) and drawing identification information for identifying the drawing (drawing A) displayed on the terminal device 20.
In addition, when synchronizing (uploading) a newly created sheet that is generated on a terminal device 20 (for example, Mr. β's terminal device 20) and is to be used for notes (additions), the CPU 11 inputs drawing identification information for identifying the drawing (drawing A) displayed on the terminal device 20 and the sheet (including sheet information and layer information (second layer) in sheet "b") from the terminal device 20 (for example, Mr. β's terminal device 20) via the communication unit 15.
The CPU 11, for example, links a drawing (drawing A) to sheet "b" and creates (stores) it in the drawing memory device 17 (here, the CPU 11 may, for example, link the drawing identification information to the drawing (drawing A), and also link the drawing identification information to sheet "b" and create (store) it in the drawing memory device 17).
The CPU 11 updates the layer correspondence table T1 in the memory unit 16 based on the drawing identification information for identifying the drawing (drawing A) displayed on the terminal device 20 and the sheet (including sheet information and layer information (second layer) on the "b" sheet).
The CPU 11 outputs to the other terminal device 20 (for example, Mr. Alpha's terminal device 20) via the communication unit 15 the newly uploaded sheet (including sheet information and layer information (second layer) in the "b" sheet) and drawing identification information for identifying the drawing (drawing A) displayed on the terminal device 20.

<Processing Step: S4>
[Processing on the terminal device 20 (tablet terminal or PC)]
The CPU 21 makes a note (adds a retouch) on a sheet selected by the user based on an instruction from the user using the terminal device 20. For example, on the terminal device 20 of user α, a note (adds a retouch) is made on sheet "a" and sheet "b," and on the terminal device 20 of user β, a note (adds a retouch) is made on sheet "c." Here, sheets "a,""b," and "c" are sheets for drawing A.

[Processing on the drawing management apparatus 10 (cloud server)]
The processing on the side of the drawing management device 10 (cloud server) in processing step S4 is "none".

<Processing Step: S5>
[Processing on the terminal device 20 (tablet terminal or PC)]
When synchronizing a sheet with notes (additions), the CPU 21 outputs drawing identification information for identifying the drawing (drawing A) displayed on the terminal device 20 and the sheet (including sheet information and layer information) to the drawing management device 10 via the communication unit 25 (here, this processing by the CPU 21 is processing on the terminal device 20 side related to uploading (uploading related to additions) to the drawing management device 10 (cloud server).
Furthermore, the CPU 21 inputs, via the communication unit 25, a sheet (with notes (added)) (including sheet information and layer information) newly uploaded from another terminal device 20 and drawing identification information for identifying the drawing (drawing A) displayed on the terminal device 20, and updates the sheet with notes (added) by referring to the layer correspondence table T2 in the memory unit 26 (here, this processing by the CPU 21 is processing on the terminal device 20 side related to downloading (downloading related to additions) from the drawing management device 10 (cloud server)).
9, the following processing is performed: In the processing of the terminal device 20, the processing order of the terminal device 20 is uploading on the terminal device 20 of Mr. α, downloading on the terminal device 20 of Mr. β, uploading on the terminal device 20 of Mr. β, and downloading on the terminal device 20 of Mr. α, but the processing order when synchronizing a sheet with notes (additions) is not particularly limited.
For example, if there are three terminal devices 20 (and if there is also a terminal device 20 for person γ), the terminal device 20 may process as follows: In the processing of the terminal device 20, the order of processing of the terminal device 20 may be uploading of person α's terminal device 20, downloading of person β's terminal device 20, uploading of person β's terminal device 20, downloading of person γ's terminal device 20, uploading of person γ's terminal device 20, and downloading of person α's terminal device 20.
Furthermore, for example, a terminal device 20 may perform upload processing for that terminal device 20, triggered at a predetermined timing (at a predetermined time interval), and then perform download processing for all other terminal devices 20.
Also, for example, a terminal device 20 may perform upload processing for that terminal device 20 at a predetermined timing (at a predetermined time interval) as a trigger, and then perform download processing for all other terminal devices 20 after a predetermined time has passed (after a predetermined period has passed).

[Processing on the drawing management apparatus 10 (cloud server)]
When synchronizing a sheet on which notes (additions) have been made on the terminal device 20, the CPU 11 inputs drawing identification information for identifying the drawing (drawing A) displayed on the terminal device 20 and the sheet (including sheet information and layer information on the sheet) from the terminal device 20 via the communication unit 15, and updates the sheet on which notes (additions) have been made on the sheet stored in the drawing memory device 17 by referring to the layer correspondence table T1 in the memory unit 16 (here, this processing by the CPU 11 is processing on the drawing management device 10 (cloud server) side related to the upload (upload related to additions) from the terminal device 20).
Furthermore, the CPU 11 outputs to the other terminal device 20 via the communication unit 15 the newly uploaded sheet (with notes (added)) (including sheet information and layer information on the sheet) and drawing identification information for identifying the drawing (drawing A) displayed on the terminal device 20 (here, this processing by the CPU 11 is processing on the drawing management device 10 (cloud server) side related to the download (download related to additions) to the terminal device 20).
In FIG. 9, the process on the drawing management apparatus 10 (cloud server) side performs the following process in accordance with the process on the terminal device 20 (tablet terminal or PC) side.
For example, in the processing of the drawing management device 10, the order of processing of the drawing management device 10 is processing related to uploading on Mr. Alpha's terminal device 20, processing related to downloading on Mr. Beta's terminal device 20, processing related to uploading on Mr. Beta's terminal device 20, and processing related to downloading on Mr. Alpha's terminal device 20, but the order of processing related to the terminal device 20 when synchronizing a sheet with notes (additions) is not particularly limited.
For example, in the case where there are three terminal devices 20 (and also a terminal device 20 for person γ), the drawing management device 10 may perform the following processing: processing related to uploading on person α's terminal device 20, processing related to downloading on person β's terminal device 20, processing related to uploading on person β's terminal device 20, processing related to downloading on person γ's terminal device 20, processing related to uploading on person γ's terminal device 20, and processing related to downloading on person α's terminal device 20.
Furthermore, for example, a terminal device 20 may perform upload processing for that terminal device 20, triggered at a predetermined timing (at a predetermined time interval), and then perform download processing for all other terminal devices 20.
Also, for example, a terminal device 20 may perform upload processing for that terminal device 20 at a predetermined timing (at a predetermined time interval) as a trigger, and then perform download processing for all other terminal devices 20 after a predetermined time has passed (after a predetermined period has passed).

<Processing Step: S6>
[Processing on the terminal device 20 (tablet terminal or PC)]
When generating a display image, the CPU 21, in response to instructions from the input unit 23, displays only sheets for which the "Sheet Selection Display (ON/OFF)" is set to "ON" on the display unit 24, superimposed on the drawing to be displayed (drawing A) (see Figure 7).

[Processing on the drawing management apparatus 10 (cloud server)]
The processing on the side of the drawing management device 10 (cloud server) in processing step S6 is "none".

The processing of the drawing management device 10 in processing step S3 is an example of a "first processing step", and the example of the "first processing step" is not limited to the processing of the drawing management device 10 in processing step S3.
Furthermore, the processing of the drawing management device 10 in processing step S5 is an example of a "second processing step" and a "third processing step," and examples of the "second processing step" and "third processing step" are not limited to the processing of the drawing management device 10 in processing step S5.

The processing by the terminal device 20 in processing step S3 is an example of a "fourth processing step", and the example of the "fourth processing step" is not limited to the processing by the terminal device 20 in processing step S3.
Furthermore, the processing of the terminal device 20 in processing step S5 is an example of the "fifth processing step" and the "sixth processing step", and examples of the "fifth processing step" and the "sixth processing step" are not limited to the processing of the terminal device 20 in processing step S5.
In processing steps S3 and S5, the drawing identification information exchanged between the drawing management device 10 (cloud server) and the terminal device 20 (tablet terminal or PC) to identify the drawing (drawing A) displayed on the terminal device 20 may be omitted from the exchange of drawing identification information if the drawing management device 10 and the terminal device 20 know that the drawing displayed on the terminal device 20 is "drawing A."
In addition, in processing step S5, the drawing management device 10 (cloud server) and the terminal device 20 (tablet terminal or PC) may omit the exchange of layer information (first layer, second layer, third layer).

<Using sheets separated by date (operation 2)>
FIG. 10A shows a flow (overview of the flow) for using sheets separated by date (operation 2).
The basic flow (overview flow) for using sheets divided by date (Operation 2) is the same as the basic flow for using sheets divided by work item (Operation 1), so only the main differences will be explained.
The main differences are as follows:
The first difference is that "Drawing C" is used instead of "Drawing A."
The second difference is that in the first layer, the "10/26" sheet is used instead of the "a" sheet.
The third difference is that in the second layer, the "10/27" sheet is used instead of the "b" sheet.
The third difference is that the third layer, the "c" sheet, is omitted.
The fourth difference is that in the sheets set to "ON" in step S30, "10/26" sheet and "10/27" sheet are used instead of "a" sheet, "b" sheet and "c" sheet.
The flow (overall flow) for using sheets separated by date (Operation 2) is shown in Figure 11. Since the flow is similar to the case for using sheets separated by work item (Operation 1), only the main differences will be explained.

In processing step S2, the "10/26" and "10/27" sheets are created, and in processing step S4, notes are added to these sheets. In FIG. 11, both Mr. Alpha and Mr. Beta add notes to the "10/26" and "10/27" sheets. As a result, the correspondence between drawing C and the "10/26" and "10/27" sheets becomes, for example, as shown in FIG. 13(a). Here, FIG. 13(a) is a drawing corresponding to the image (FIG. 4) of the correspondence between drawings and layers in the case where sheets are used divided by work item (Operation 1).
In Figure 13(a), the "10/26" sheet, which corresponds to the first layer, is associated with the "10/27" sheet, which corresponds to the second layer. Notes "A" and "C" have been added to the "10/26" sheet as notes, and notes "B" and "D" have been added to the "10/27" sheet as notes.
14(a) is an image of the display screen, showing an example of the screen when the display of the "10/26" sheet and the "10/27" sheet is set to "ON." Here, FIG. 14(a) is a drawing corresponding to the image (FIG. 7) of the correspondence relationship between drawings and layers in the case where sheets are used by dividing them into work items (Operation 1).
In processing steps S3 and S5 of Figure 11, the drawing identification information exchanged between the drawing management device 10 (cloud server) and the terminal device 20 (tablet terminal or PC) to identify the drawing (drawing C) displayed on the terminal device 20 may be omitted from the exchange of drawing identification information if the drawing management device 10 and the terminal device 20 know that the drawing displayed on the terminal device 20 is "drawing C."
In addition, in processing step S5, the drawing management device 10 (cloud server) and the terminal device 20 (tablet terminal or PC) may omit the exchange of layer information (first layer, second layer).

<Case of using sheets separately for different vendors (Operation 3)>
FIG. 10B shows a flow (overview of the flow) when sheets are used separately for different vendors (operation_3).
The basic flow (overview flow) for using sheets divided by contractor (Operation 3) is the same as the basic flow for using sheets divided by work item (Operation 1), so only the main differences will be explained.
The main differences are as follows:
The first difference is that "Drawing E" is used instead of "Drawing A."
The second difference is that in the first layer, an "a construction" sheet is used instead of an "a" sheet.
The third difference is that in the second layer, the "b equipment" sheet is used instead of the "b" sheet.
The third difference is that the third layer, the "c" sheet, is omitted.
The fourth difference is that in the sheets set to "ON" in step S30, the "a" sheet, the "b" sheet, and the "c" sheet are replaced with the "a Construction" sheet and the "b Equipment" sheet.
The flow (overall flow) for the case where sheets are used by dividing by contractor (Operation_Part 3) is shown in Figure 12. Since the flow is similar to the case where sheets are used by dividing by work item (Operation_Part 1), only the main differences will be explained.

In process steps S2 to S4, the following processes are executed.
In processing step S2, a "construction" sheet and a "facility" sheet are created.
In processing step S3, the following processing is executed in the terminal device 20 (for example, the terminal device 20 of Construction Company A's Mr. α), the terminal device 20 (for example, the terminal device 20 of Equipment Company B's Mr. β), and the drawing management device 10.
The terminal device 20 (for example, the terminal device 20 of Mr. A Construction α) executes processing related to synchronization (uploading) for the "A Construction" sheet, and the drawing management device 10 executes processing related to the synchronization (uploading).
The terminal device 20 (for example, the terminal device 20 of person β of facility b) executes processing related to synchronization (downloading) for the "construction a" sheet, and the drawing management device 10 executes processing related to the synchronization (downloading).
The terminal device 20 (for example, the terminal device 20 of person β at facility b) executes processing related to synchronization (uploading) of the "facility b" sheet, and the drawing management device 10 executes processing related to the synchronization (uploading).
The terminal device 20 (for example, the terminal device 20 of Mr. A Construction Company A) executes processing related to synchronization (downloading) for the "B Equipment" sheet, and the drawing management device 10 executes processing related to said synchronization (downloading).
In processing step S4, notes are added to these sheets.
In Figure 12, Mr. Alpha of Construction A adds to the "Construction A" sheet, and Mr. Beta of Equipment B adds to the "Equipment B" sheet. As a result, the correspondence between Drawing E and the "Construction A" and "Equipment B" sheets becomes, for example, as shown in Figure 13(b). Here, Figure 13(b) is a drawing that corresponds to the image (Figure 4) of the correspondence between drawings and layers in the case where sheets are used by dividing them into work items (Operation 1).
13B, the "a Construction" sheet, which corresponds to the first layer, and the "b Equipment" sheet, which corresponds to the second layer, are associated with each other. The "a Construction" sheet has a note "A" added to it, and the "b Equipment" sheet has a note "B" added to it.
14(b) is an image of the display screen, which is an example of the screen when the display of the "a Construction" sheet and the "b Equipment" sheet is set to "ON." Here, FIG. 14(b) is a drawing corresponding to the image (FIG. 7) of the correspondence relationship between drawings and layers in the case where sheets are used by dividing them into work items (operation 1).
In processing steps S3 and S5 of Figure 12, the drawing identification information exchanged between the drawing management device 10 (cloud server) and the terminal device 20 (tablet terminal or PC) to identify the drawing (drawing E) displayed on the terminal device 20 may be omitted from the exchange of drawing identification information if the drawing management device 10 and the terminal device 20 know that the drawing displayed on the terminal device 20 is "drawing E."
In addition, in processing step S5, the drawing management device 10 (cloud server) and the terminal device 20 (tablet terminal or PC) may omit the exchange of layer information (first layer, second layer, third layer).

As described above, the display system 1 according to the first embodiment allows users to create multiple sheets associated with drawings and add notes to these sheets separately. This allows users to display and compare notes added to multiple sheets on top of each other. For example, there is no need to switch screens when checking notes on multiple sheets, and notes on multiple sheets can be compared and checked on a single screen. As an example, the display system 1 according to the first embodiment allows users to link each note added to design document information consisting of one piece of information (for example, at least one piece of information from drawings, documents, photographs, etc.) to each of multiple layers, allowing users to display and compare each note on top of each other on a single screen.

Second Embodiment
In the first embodiment, memos are added to a transparent sheet and then overlaid on the drawing. In the second embodiment, memos are added to a sheet on which the drawing is drawn (i.e., a copy of the drawing (the drawing data itself)), and the sheet on which the drawing and memos are written are overlaid.

Figure 15 shows the system configuration of a display system 101 according to the second embodiment. The display system 101 includes a drawing management device 110 and multiple terminal devices 120. The drawing management device 110 and the multiple terminal devices 120 are connected to each other via a communications network NW such as the Internet so that data can be communicated between them. The following explanation focuses on the differences from the first embodiment.

Figure 16 is a block diagram showing the functional configuration of the drawing management device 110. The drawing management device 110 includes a CPU (Central Processing Unit) 11, a RAM (Random Access Memory) 12, an input unit 13, a display unit 14, a communication unit 15, a storage unit 16, and a drawing storage device 117, with each unit connected via a bus 18.

The drawing storage device 117 shown in Figure 16 is a storage device that stores information in a readable and writable manner. The drawing storage device 117 stores multiple layers, each containing notes (additions) written on a drawing, on a drawing-by-drawing basis. A layer is a virtual sheet on which drawings and notes (additions) on the drawings are recorded. For example, in the drawing storage device 117, multiple layers are stored for each drawing of a construction project in a folder provided for that construction project.

<Using sheets divided by work items (operation 1)>
FIG. 17 is an image of the correspondence relationship between drawings and layers in the second embodiment. Here, FIG. 17 is a drawing corresponding to the image of the correspondence relationship between drawings and layers in the first embodiment ( FIG. 4 ). In FIG. 17 , assuming a case <Operation 1> in which sheets are used by dividing by work item, sheet "a" corresponding to the first layer, sheet "b" corresponding to the second layer, and sheet "c" corresponding to the third layer are associated with drawing A. Note "A" has been added as a memo to sheet "a" along with drawing A, note "B" has been added as a memo to sheet "b" along with drawing A, and note "C" and "D" have been added as memos to sheet "c" along with drawing A.

<<Operation of the display system according to the second embodiment>>
The following shows the operation flow when multiple users use the present invention simultaneously.
<Using sheets divided by work items (operation 1)>
A flow (overview of the flow) for using sheets divided by work items (operation 1) is shown in Fig. 20. Here, in the case of using sheets divided by work items <operation 1>, the basic flow in the second embodiment is the same as the basic flow in the first embodiment.

First, the user of the terminal device 120 operates the terminal device 120 to open drawing A on the display screen (step S110).
Next, the user of the terminal device 120 operates the terminal device 120 to create multiple sheets including drawing A (on which drawing A is written) and add notes to the created sheets (step S120). For example, the user creates sheet "a" including drawing A and adds notes to the created sheet "a" (step S121). The user also creates sheet "b" including drawing A and adds notes to the created sheet "b" (step S122). The user also creates sheet "c" including drawing A and adds notes to the created sheet "c" (step S123).

Next, the user operates the terminal device 120 to set the display of each sheet to "ON/OFF" (step S130). Drawings and revised notes on sheets with the display "ON" are displayed on the display screen, while drawings and revised notes on sheets with the display "OFF" are not displayed on the display screen.
For example, in step S130 of FIG. 20 , the display switch for sheet "a" is turned "ON," the display switch for sheet "b" is turned "ON," and the display switch for sheet "c" is turned "ON." The display switches here are controls that switch the sheet display "ON/OFF," and are displayed, for example, on the screen. As a result, the notes for sheets "a,""b," and "c" are displayed superimposed on the drawing A (see FIG. 7A). Here, for example, if the display switch for sheet "a" is turned "ON," the display switch for sheet "b" is turned "ON," and the display switch for sheet "c" is turned "OFF," the notes for sheets "a" and "b" are displayed superimposed on the drawing A (see FIG. 7B).
<Using sheets separated by date (operation 2)>
FIG. 21A shows a flow (overview of the flow) for using sheets separated by date (operation 2).
The basic flow (overview flow) for using sheets separated by date (Operation 2) is the same as the basic flow for using sheets separated by work items in the second embodiment (Operation 1), so only the main differences will be explained.
The main differences are as follows:
The first difference is that "Drawing C" is used instead of "Drawing A."
The second difference is that in the first layer, the "10/26" sheet is used instead of the "a" sheet.
The third difference is that in the second layer, the "10/27" sheet is used instead of the "b" sheet.
The third difference is that the third layer, the "c" sheet, is omitted.
The fourth difference is that, in the sheets set to "ON" in step S130, "10/26" sheet and "10/27" sheet are used instead of "a" sheet, "b" sheet and "c" sheet.
For example, in step S130 relating to Figure 21(a), the display switch for the "10/26" sheet is turned "ON" and the display switch for the "10/27" sheet is turned "ON." The display switches here are operating units that switch the sheet display "ON/OFF," and are displayed, for example, on the screen. As a result, the notes for the "10/26" sheet and the "10/27" sheet are displayed superimposed on the drawing A (see Figure 14(a)).
<Case of using sheets separately for different vendors (Operation 3)>
FIG. 21B shows a flow (overview of the flow) for the case where sheets are divided among vendors and used (operation_3).
The basic flow (overview flow) for using sheets divided by contractor (Operation 3) is the same as the flow for using sheets divided by work item in the second embodiment (Operation 1), so only the main differences will be explained.
The main differences are as follows:
The first difference is that "Drawing E" is used instead of "Drawing A."
The second difference is that in the first layer, an "a construction" sheet is used instead of an "a" sheet.
The third difference is that in the second layer, the "b equipment" sheet is used instead of the "b" sheet.
The third difference is that the third layer, the "c" sheet, is omitted.
The fourth difference is that in the sheets set to "ON" in step S130, the "a" sheet, the "b" sheet, and the "c" sheet are replaced with the "a Construction" sheet and the "b Equipment" sheet.
For example, in step S130 relating to Figure 21(b), the display switch for the "Construction a" sheet is turned "ON" and the display switch for the "Equipment b" sheet is turned "ON." The display switches here are operating units that switch the sheet display "ON/OFF," and are displayed, for example, on the screen. As a result, the notes for the "Construction a" sheet and the "Equipment b" sheet are displayed superimposed on the drawing A (see Figure 14(b)).

As described above, the display system 101 according to the second embodiment also achieves the same effects as the first embodiment. Specifically, the display system 101 according to the second embodiment allows you to create multiple sheets, including drawings (with drawings written on them), and add notes to these sheets separately. This allows you to display and compare notes added to multiple sheets by overlapping them. For example, if you want to check notes on multiple sheets, there is no need to switch screens, and you can compare and check notes on multiple sheets on a single screen.

[Third embodiment]
In the first and second embodiments, the content of the revised memo is displayed in an overlapping manner. In the third embodiment, the content of the memo is not displayed, but is displayed so that only the fact that a memo has been revised can be seen. The display screen in the third embodiment will be described with reference to Fig. 22. Fig. 22 is an image of the display screen in the third embodiment.

For example, as shown in Figure 22(a), suppose a construction worker at Construction A adds a memo 91 to a staff member at Facility B. This memo 91 consists of a frame 91a and instructions (text) 91b for the staff member at Facility B. Suppose, for example, that the staff member at Construction A does not want the instructions (text) 91b for the staff member at Facility B to be seen by anyone other than the staff member at Facility B. In this case, the staff member at Construction A sets the instructions (text) 91b to be visible only to the staff member at Facility B. As a result, when someone other than the staff member at Facility B views the drawing (or document or photograph), the instructions (text) 91b are not displayed, and only the frame 91a of the memo 91 is displayed, as shown in Figure 22(b). Therefore, even people other than the staff member at Facility B can recognize the existence of the memo 91 and add their own memo 92 in a location that avoids the memo 91 (a location that does not overlap the memo 91).

The above describes an embodiment of the present invention, but the present invention is not limited to this and can be implemented within the scope of the claims.
