Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to a mobile terminal device carried by, for example, a sales representative or the like, a slide information managing system, and a control method of a mobile terminal 
       BACKGROUND FIELD 
       [0002]    Conventionally, the mobile terminal device has been offered which supports sales activity of a sales representative (Patent Literature 1, for example). 
         [0003]    Information provided to such a mobile terminal device is often provided by PDF (“Portable Document Format”) or the like. This is because PDF or the like has the property that enables documents, images, or the like to be viewed in substantially unvaried state under all the environments without being influenced by a specific environment.

       SUMMARY OF THE INVENTION 
     Problems to Be Solved By the Invention 
       [0005]    However, it take time to edit or the like materials created in PDF format, and thus it is difficult for a sales representative who is not specifically familiar with the format concerned to perform edits or the like. 
         [0006]    For this reason, it has been very difficult in fact for each of sales representatives to create the most appropriate sales material for each customer of his/hers by editing the materials in PDF or the like, aside from the theory. 
         [0007]    Then, if the materials are created so that sales representatives or the like do not need to perform edits beyond his/her ability, a large amount of effort is required to create the materials, and also the amount of data of the whole materials increases. There has thus been a problem in which this is not desirable in view of a mobile terminal device. 
         [0008]    Furthermore, it is a commonly used technique that a screen is shifted from a main explanatory slide to a relevant literature at the time of simultaneously offering an explanation of relevant literatures or the like in relation to the explanation of slides such as PDF by means of a mobile terminal 
         [0009]    However, it is often difficult to transfer the screen to the previous explanatory slides after the relevant literatures are explained, and thus the unnecessary interval in the explanation is generated by that much. There has thus been a problem in which the explanation to a customer of a sales representative or the like becomes less effective. 
         [0010]    For this reason, the object of the present invention is to provide a mobile terminal device in which a user such as a sales representative or the like can easily perform edits, the amount of data materials is not increased as a whole, and no unnecessary interval is generated during the explanation, thereby preventing the effect of the explanation by a user to a person of interest such as a customer from decreasing, a slide information managing system, and a control method of a mobile terminal. 
       Means for Solving the Problem 
       [0011]    According to the present invention, the object described above is achieved by a mobile terminal device, comprising a display displaying various information, wherein slide information to be displayed on the display includes a plurality of pieces of the slide information independently stored as the slide information for each screen, the pieces of the slide information are configured to be able to be combined arbitrarily; the slide information includes main explanatory slide information for use in a main explanation, and relevant slide information as being the information in relation to the main explanatory slide information; and the slide information is configured to be able to be stored in association with the main explanatory slide information, and the display is configured to be able to display the main explanatory slide information associated with the relevant slide information by a transfer for one screen from the relevant slide information. 
         [0012]    According to the configuration described above, it is configured so that slide information to be displayed on the display includes a plurality of pieces of the slide information to be independently stored as the slide information for each screen, and the pieces of the slide information are configured to be able to be combined arbitrarily. 
         [0013]    For example, in the conventional slide information such as PDF, a plurality of PDF slides is formed as a certain unit of chunk, and is stored so that it is difficult to be separated into individual PDF slides. In this case, it is difficult for a user such as a sales representative to clip or the like a part of the PDF slides. If it is possible, a complicated operation has been required. Consequently, it has been difficult for each user to perform edits such as rearrangement of the order of PDF slides in accordance with each customer. 
         [0014]    In this regard, in the configuration described above, the slide information includes a plurality of pieces of the slide information to be independently stored as the slide information for each screen, and the pieces of the slide information are configured to be able to be combined arbitrarily. Therefore, the user can easily perform edits of the slides or the like without the necessity of complicated operation. 
         [0015]    Furthermore, according to the configuration described above, the slide information includes main explanatory slide information for use in a main explanation, and relevant slide information as being the information in relation to the main explanatory slide information, and the relevant slide information is configured to be able to be stored in association with the main explanatory slide. 
         [0016]    Conventionally, it has been impossible to freely rearrange and establish the association of slides such as PDF. Therefore, when the slides such as PDF of main explanatory slide information are associated with the slides of the relevant slide information, it has been necessary to generate a set to which the slides of the relevant slide information for each slide of each main explanatory slide information, in every main explanatory slide information. 
         [0017]    Consequently, when there is a plurality of main explanatory slides with which the same relevant slide information is associated, the same relevant slide information have to be associated with each main explanatory slide to generate the set thereof As a result, the mobile terminal device has to store a plurality of the same pieces of relevant slide information or the like, and thus the amount of data has been increased. 
         [0018]    In this regard, in the configuration described above, it is configured so that the slide information includes a plurality of pieces of the slide information independently stored as the slide information for each screen, the pieces of the slide information are configured to be able to be combined arbitrarily, and the relevant slide information can be stored in association with the main explanatory slide. 
         [0019]    More specifically, in the configuration described above, it is not necessary to form the main explanatory slide information and the relevant slide information as being a set, and thus it is possible to achieve the configuration of one relevant slide information associated with a plurality of pieces of main explanatory slide information. The mobile terminal device thus is not required to store a plurality of the same pieces of relevant slide information, and thus the amount of data can be reduced by that much. 
         [0020]    Furthermore, in the configuration described above, the display can display the main explanatory slide information associated with the relevant slide information by a transfer for one screen from the relevant slide information. 
         [0021]    Consequently, a user can display the main explanatory slide information on the display, and then display the relevant slide information associated with the main explanatory slide information to offer an explanation, followed by promptly displaying the previous main explanatory slide information on the display. 
         [0022]    Therefore, since no interval is generated in the transfer from the relevant slide information to the previous main explanatory slide information as in the conventional case, no unnecessary interval is generated at the time of explaining the main explanatory slide information. The explanation by a user to a person of interest such as a customer thus does not becomes less effective, and it is thus possible to offer an effective explanation. 
         [0023]    Preferably, it is characterized in that the slide information includes a PDF (“Portable Document Format”) format. 
         [0024]    Preferably, it is characterized in that it is configured to be able to communicate with a slide information management device managing the slide information. 
         [0025]    According to the present invention, the object described above is achieved by a control method of a mobile terminal device, wherein slide information to be displayed on the display displaying various information includes a plurality of pieces of the slide information independently stored as the slide information for each screen, the pieces of the slide information are configured to be able to be combined arbitrarily; the slide information includes main explanatory slide information for use in a main explanation, and relevant slide information as being the information in relation to the main explanatory slide information; and the slide information is configured to be able to be stored in association with the main explanatory slide information, and the display is configured to be able to display the main explanatory slide information associated with the relevant slide information by a transfer for one screen from the relevant slide information. 
       Advantageous of the Invention 
       [0026]    The present invention has the advantage of capable of providing a mobile terminal device, a slide information managing system, and a control method of mobile terminal in which a user such as a sales representative can easily perform edits, the amount of data materials is not increased as a whole, and no unnecessary interval is generated during the explanation, thereby preventing the effect of the explanation by a user to a person of interest such as a customer from decreasing.

     DESCRIPTION OF EMBODIMENTS 
       [0039]    Preferred embodiments of the present invention will be described below in detail with reference to the attached drawings. 
         [0040]    In addition, the embodiments described below are preferred embodiments of the present invention, and thus include a variety of technically desirable limitation. The scope of the present invention, however, shall not be limited to those embodiments unless there is any description of limitation on the present invention in the explanation below. 
         [0041]      FIG. 1  is a schematic diagram showing a slide information managing system of the present invention, e.g., a managing system of explanatory materials for doctor  1 . 
         [0042]    As shown in  FIG. 1 , the managing system of explanatory materials for doctor  1  has a management server  3 , for example, which is an information management device for managing explanatory materials for doctors made with slide information such as PDF. The management server  10  is in possession of a pharmaceutical company  4 , for example. 
         [0043]    Furthermore, the system  1  has a tablet terminal  20 , for example, which is a mobile terminal device. The tablet terminal  20  is the terminal which is held by each MR (medical representative) of the pharmaceutical company  4  for use in providing medical information while meeting doctors in a hospital or the like. 
         [0044]    As shown in  FIG. 1 , the tablet terminal  20  has, at the center thereof, a “touch panel type display  21 ” having a vertical long rectangular shape. A touch panel is electronic equipment which is a combination of a display, e.g., a display, and a position input device, and also is an input device in which a user can input various information by touching an indication on the display. 
         [0045]    Furthermore, the tablet terminal  20  has an input button  22  in addition to the touch panel type display  21 . 
         [0046]    In addition, as shown in  FIG. 1 , the tablet terminal  20  is configured to be able to communicate with the management server  10  which is managed by the pharmaceutical company  4 . 
         [0047]    The tablet terminal  20  and the management server  10  described above have a computer, and the computer has CPU (Central Processing Unit; not shown), RAM (Random Access Memory), and ROM (Read Only Memory) or the like which are connected to one another via a bus or the like. 
         [0048]      FIG. 2  is a schematic block diagram showing a main configuration of the management server  10  in  FIG. 1 . As shown in  FIG. 2 , the management server  10  has a “database of explanatory materials for doctor  11 ”. 
         [0049]    As shown in  FIG. 2 , the database of explanatory materials for doctor  11  has “explanatory material data for cardiovascular specialists”, for example. The data concerned includes “Explanatory Slides Nos.  1  to  4 ” which are the main slide information constituted by, e.g., PDF or the like as “basic explanatory slide of high blood pressure”. 
         [0050]    Furthermore, as “relevant literatures of the basic explanatory slide”, relevant slide information in relation to the explanatory slides Nos.  1  to  4 , e.g., “Literature Slides Nos.  101  to  108 ” is included. 
         [0051]    Furthermore, the database of explanatory materials for doctor  11  has “Explanatory Slides Nos.  11  to  14 ” as “explanatory slide of typical case such as a case of high blood pressure”, and has “Literature Slides Nos.  111  to  114 ” as “relevant literature of explanatory slide of a typical case”. 
         [0052]    Furthermore, the database of explanatory materials for doctor  11  has “Explanatory Slides Nos.  21  to  24 ” as “typical therapeutic medicine explanatory slides for therapeutic medicine”, and has “Literature Slides Nos.  121  to  124 ” as “relevant literature of typical therapeutic medicine explanatory slide”. 
         [0053]    Furthermore, the management server  10  has a “server controller  12 ”. The server controller  12  is configured to control the database of explanatory materials for doctor  11 , and also to control a “server side communication device  13 ” for communicating with the tablet terminal  20 , a “server side display  14 ” displaying various information, and a “server side input device  15 ”, as shown in  FIG. 2 . 
         [0054]      FIG. 3  is a schematic block diagram showing a main configuration of the tablet terminal  20  shown in  FIG. 1 . 
         [0055]    As shown in  FIG. 3 , the tablet terminal  20  has a “terminal controller  23 ”. The terminal controller  23  controls a “touch panel type display  21 ” and an “input button  22 ” shown in  FIG. 1 , as well as controls a “terminal side communication device  24 ” for communicating with the management server  10  in  FIG. 1 . 
         [0056]    Furthermore, the terminal controller  23  also controls a “first various information storage portion  30 ” and a “second various information storage portion  40 ” shown in  FIG. 3 . 
         [0057]      FIGS. 4 and 5  are schematic block diagrams showing a main configuration of the first various information storage portion  30  and the second various information storage portion  40  in  FIG. 3 . The details thereof will be described later. 
         [0058]    In the present embodiment, the description will be made below using the example of an MR (medical representative) of the pharmaceutical company  4  providing two doctors of cardiovascular department of a hospital (a doctor a and a doctor β) with medical information employing the tablet terminal  20  in  FIG. 1 . 
         [0059]      FIG. 6  is a schematic explanatory view showing a configuration of slides by which the MR intends to offer an explanation to the doctor α. Since the doctor a is a resident, the explanation is configured to be made with an emphasis on relatively basic explanation. 
         [0060]    More specifically, the MR has it in mind to display the slide information, e.g., slides as follows on the touch panel type display  21  of the tablet terminal  20 . 
         [0061]      FIG. 7  is a schematic explanatory view showing the configuration of slides by which the MR intends to offer an explanation to a doctor β. Since the doctor β is a head physician, the explanation is configured so that the basic explanation will be omitted and the emphasis is on the explanation of cases and therapeutic medicines. 
         [0062]      FIGS. 8 to 12  are schematic flow charts showing the operational example of the managing system of explanatory materials for doctor  1 . 
         [0063]    At step ST (hereinafter referred to as “ST”)  1  in  FIG. 8 , the MR uses his/her own tablet terminal  20  in  FIG. 1  to communicate with the management server  10 . Then, all or a part of “explanatory material data for cardiovascular specialists” is acquired from a “database of explanatory materials for doctor  11 ” in the management server  10  to the MR&#39;s own tablet terminal  20  to store the data in a “storage portion for explanatory materials for doctor  31 ” of the tablet terminal  20  shown in  FIG. 4 . 
         [0064]    Consequently, the tablet terminal  20  can subsequently create explanatory materials for each doctor offline without communicating with the management server  10 , and display the information on the touch panel type display  21  to offer an explanation to each doctor. 
         [0065]    In this manner, since the explanation can be offered only by the tablet terminal  20  offline, the system is extremely easy to use. 
         [0066]      FIG. 9  is a schematic flow chart showing the steps of creating explanatory materials for doctor dedicated to the doctor α. 
         [0067]    The MR executes at the steps in  FIG. 9  the preparation of slides for the explanation shown in  FIG. 6 . 
         [0068]    First, at ST 11  in  FIG. 9 , explanatory slides Nos.  1  to  4 ,  11  to  14 , and  21  to  24  such as PDF in the storage portion for explanatory materials for doctor  31  are selectively displayed on the touch panel type display  21  to select the necessary explanatory slides and the display order thereof. 
         [0069]    For example, “Explanatory Slides Nos.  1  to  4 ,  11 ,  12 , and  21 ” which are the explanatory slides to be used in  FIG. 6  are selected and stored in a storage portion for explanatory slide for doctor α  32 . 
         [0070]    Then, the procedure proceeds to ST 12 . At ST 12 , “Literature Slides Nos.  101  to  108 ,  111  to  114 , and  121  to  124 ” such as PDF in the storage portion for explanatory materials for doctor  31  are displayed on the touch panel type display  21  to select the necessary literature slides and the display order thereof. 
         [0071]    For example, the literature slides Nos.  101  to  108 ,  111 ,  112 , and  121  are selected to be displayed in this order, and are stored in a “literature slide storage portion for the doctor a  33 ”. 
         [0072]    Then, the procedure proceeds to ST 13 . At ST 13 , a group of literature slides associated with the explanatory slides of the storage portion for explanatory slide for doctor a  33  is designated and stored. 
         [0073]    For example, in the case of  FIG. 6 , an explanatory slide No.  3 , a reference group  1  (literature slides Nos.  105  to  108 ), and a reference group  2  (literature slides Nos.  101  to  104 ) are associated with one another, and stored in a “storage portion for explanatory material-related information for doctor α  34 ”. 
         [0074]    Furthermore, an explanatory slide No.  11  and a reference group (literature slide Nos.  111  and  112 ) are associated with each other, and also an explanatory slide No.  21  and a reference group (literature slide No.  121 ) are associated with each other, so as to store them in the storage portion for explanatory material-related information for doctor α  34 . 
         [0075]    In this manner, in the present embodiment, the explanatory slide and the literature slide are independently stored for each display on a single display screen such as explanatory slide No.  1 . The selection thus can be made for each slide to determine the display order of the slides. 
         [0076]    Furthermore, since the explanatory slide and the literature slide can be associated with each other for each slide arbitrarily, the system is extremely easy to use for the user such as MR who carries out the aforementioned operation by the tablet terminal  20 . 
         [0077]    In particular, even the MR who does not have an intimate knowledge of PDF format of slides or the like can readily perform the operation. 
         [0078]      FIG. 10  is a schematic flow chart showing the steps of creating explanatory materials for doctor dedicated to the doctor β. 
         [0079]    The MR executes at the steps in  FIG. 10  the preparation of slides for the explanation shown in  FIG. 7 . 
         [0080]    First, at ST 21 , explanatory slides Nos.  1  to  4 ,  11  to  14 , and  21  to  24  such as PDF in the storage portion for explanatory materials for doctor  31  in  FIG. 4  are displayed on the touch panel type display  21  to select the necessary explanatory slides and the display order thereof 
         [0081]    For example, Explanatory Slides Nos.  11  to  14 , and  21  to  24  are selected to be displayed in this order, and stored in a “storage portion for explanatory slide for doctor β  35 ”. 
         [0082]    Then, the procedure proceeds to ST 22 . At ST 22 , Literature Slides Nos.  101  to  108 ,  111  to  114 , and  121  to  124  such as PDF in the storage portion for explanatory materials for doctor  31  are displayed on the touch panel type display  21  to select the necessary literature slides and the display order thereof. 
         [0083]    For example, “Literature Slides Nos.  111  to  114 ,  121  to  124 ” which are to be used in 
         [0084]      FIG. 7  are selected to be displayed in this order, and are stored in a “storage portion for literature slide for doctor β  36 ”. 
         [0085]    Then, the procedure proceeds to ST 23 . At ST 23 , a group of literature slides associated with the explanatory slides is designated and stored. For example, an explanatory slide No.  11  and a reference group (literature slide Nos.  111  to  114 ) are associated with each other, and stored in a “storage portion for explanatory material-related information for doctor β  37 ”. Furthermore, an explanatory slide No.  21  and a reference group (literature slides Nos.  121  to  124 ) are associated with each other, and stored in the storage portion for explanatory material-related information for doctor β  37 . 
         [0086]    In this manner, in the present embodiment, if the explanatory slides for the doctor a and the literature slides associated therewith are different from the explanatory slide for the doctor  13  and the literature slide associated therewith, it is not necessary to create separate slide sets respectively as in a conventional case. One explanatory slide and one literature slide can be utilized as slides for both the doctors, respectively. 
         [0087]    Therefore, it is possible to reduce the amount of data to be stored in the tablet terminal  20  compared with the conventional case. 
         [0088]      FIGS. 11 and 12  are schematic flow charts showing the steps of displaying slides shown in  FIG. 6  on the tablet terminal  20  while meeting with the doctor α. 
         [0089]    In addition, the display of slides in  FIG. 7  for the explanation to the doctor β is almost the same as that in the case of the doctor α, and the explanation thereof will be omitted. 
         [0090]    First, the MR turns on his/her tablet terminal  20 . Then, at ST 31 , a selection screen of the explanatory slide storage portion is displayed on the touch panel type display  21 , and the MR operates it to select the “storage portion for explanatory slide for doctor α  32 ”. 
         [0091]    Then, the procedure proceeds to ST 32 . At ST 32 , a “display slide specifying portion (program)  41 ” in  FIG. 5  is activated to specify “display slides” in accordance with the display order of “Explanatory Slides” of the “storage portion for explanatory slide for doctor α  32 ”. 
         [0092]    Specifically, as shown in  FIG. 6 , “Explanatory Slide No.  1 ” is displayed on the touch panel type display  21 . 
         [0093]    Then, the procedure proceeds to ST 33 . At ST 33 , a “relevant information determining portion (program)  42 ” in  FIG. 5  is activated to determine whether or not the explanatory slide to be displayed is associated with a “reference group”. 
         [0094]    Specifically, the determination is made with reference to the storage portion for explanatory material-related information for doctor α  34  in  FIG. 4 . 
         [0095]    No display group is associated with “Slide No.  1 ”, and thus the procedure proceeds to ST 34 . 
         [0096]    At ST 34 , the explanatory slide to be displayed is displayed as it is. 
         [0097]    Then, the procedure proceeds to ST 35 . At ST 35 , it is determined whether or not a slide change instruction is input via the touch panel type display  21 . If the instruction is input, the procedure proceeds to ST 32  to display “Explanatory Slide No.  2 ” as shown in  FIG. 6 . 
         [0098]    In this manner, if “Explanatory Slide No.  3 ” is displayed, it is determined at ST 33  that a “reference group” is associated therewith, and then procedure proceeds to ST 36 . 
         [0099]    At ST 36 , as shown in  FIG. 6 , a mark of “Reference  1 ” corresponding to a reference group  1  and that of “Reference  2 ” corresponding to a reference group  2  are displayed on “Explanatory Slide No.  3 ”. 
         [0100]    Then, the procedure proceeds to ST 37 . At ST 37 , it is determined whether or not the MR touches and clicks “Reference  1 ” or “Reference  2 ” on the “Explanatory Slide No.  3 ”. 
         [0101]    At ST 37 , when “Reference  1 ” is clicked, for example, the procedure proceeds to ST 38  in  FIG. 12 . 
         [0102]    At ST 38 , a “literature slide display portion (program)  43 ” in  FIG. 5  is activated to specify “display slides (reference group  1  (literature slides Nos.  105  to  108 ,  111 ,  112 ,  121 ))” in accordance with the display order of the literature slides of the “storage portion for literature slides for doctor α  33 ” with reference to the “storage portion for explanatory material-related information for doctor α  34 ” and the “storage portion for literature slide for doctor α  33 ”, and display the slides with a “BACK” mark. 
         [0103]    More specifically, as shown in  FIG. 6 , “Literature Slide No.  105 ” is displayed at first, and the “BACK” mark is displayed at the same time. 
         [0104]    Then, the procedure proceeds to ST 39 . At ST 39 , it is determined whether or not the “BACK” mark is touched and clicked. If it is determined at ST 39  the “BACK” mark is not clicked, the procedure proceeds to ST 40 . 
         [0105]    At ST 40 , it is determined whether or not a slide change instruction is input. If the slide change instruction is input from the touch panel type display  21 , the procedure proceeds to ST 38  to display the next “literature Slide No.  106 ” in  FIG. 6  is displayed with the “BACK” mark. 
         [0106]    In this manner, if the literature slides are displayed in sequence, “Literature Slide No.  108 ” in  FIG. 6  is displayed with the “BACK” mark, and the “BACK” mark is clicked at ST 39 , the procedure proceeds to ST 41 . 
         [0107]    At ST 39  and ST 41 , a “BACK mark execution portion (program)  44 ” in  FIG. 5  is executed. If it is determined that a “BACK” mark is clicked, “Explanatory Slide No.  3 ” is specified which is the explanatory slide with which the reference group concerned, i.e., the reference group  1  in the aforesaid example, is associated, with reference to the explanatory literature-related information storage portion for doctor α  34 . In the next screen, 
         [0108]    “Explanatory Slide No.  3 ” which is the explanatory slide concerned is displayed on the touch panel type display  21 . 
         [0109]    Therefore, even if the MR explains “Literature Slide No.  105 ” to “Literature Slide No.  108 ” which are the relevant literatures while explaining “Explanatory Slide No.  3 ”, it is possible to promptly return to “Explanatory Slide No.  3 ” in the next screen only by clicking the “BACK” mark of “Literature Slide No.  108 ”. 
         [0110]    Consequently, it is possible to prevent the occurrence of adverse effect as in the conventional case, i.e., it takes time to transfer from the literature slide to the explanatory slide, so that the explanation by the MR is interrupted resulting in decrease in the effect of explanation. 
         [0111]    More specifically, it is possible to promptly return the screen from the explanation of the literature slide to the previous explanatory slide screen. It is possible to return to the previous explanatory slide in regard to any of “Literature Slide No.  105 ” to “Literature Slide No.  108 ” in  FIG. 6 . 
         [0112]    Consequently, the MR can promptly return to the previous explanatory slide, i.e., “Explanatory Slide No.  3 ” at any time by clicking the “BACK” mark at an arbitrary timing while seeing the response of the doctor α. 
         [0113]    Furthermore, as shown in  FIG. 6 , a plurality of reference groups can be associated with a single “Explanatory Slide No.  3 ” to form a “Reference” mark for transferring to each group. In this case, the MR can select any of desirable one as appropriate by seeing the response of the doctor to be explained. 
         [0114]    Furthermore, in contrast to the present embodiment, it is possible to configure that, if the selected “Reference” mark, e.g., the mark of “Reference  2 ”, is selected, such a fact is stored, and, in order to preferentially display the literature slide of “Reference  2 ” next time, “Reference  2 ” is changed to “Reference  1 ” so that the fact concerned is notified to the MR. 
         [0115]    The procedure proceeds from ST 41  to ST 42 . At ST 42 , “Explanatory Slide No.  4 ” which is the explanatory slide following “Explanatory Slide No.  3 ” in  FIG. 6  is displayed on the touch panel type display  21 . 
         [0116]    In this manner, all the explanatory slides in  FIG. 6  to Explanatory Slide No.  21  are displayed, the explanation by the MR to the doctor a is finished. 
         [0117]    Furthermore, the explanation in  FIG. 7  to the doctor β is performed in the same manner. 
         [0118]    In addition, the present invention is not limited to the embodiments described above. For example, it is possible to apply the present invention to the explanation of “presentation of materials and simulation along with opening a new store”, etc., not for the MR. 
         [0119]    More specifically, it is possible to display a detailed simulation screen (data of cash and deposits of a customer or the like) as a literature slide relative to an explanatory slide of specific regional characteristics, simulation of customer attraction, and simulation of store planning and borrowing funds.
