Abstract: When an information processing apparatus performs a process, it stores history data itemizing a process type, an apparatus in charge of processing, a person for instructing the process, a process object information and execution time. Then, necessary history data are searched for by designating the conditions in the items, desired history data is selected from the history data that are found, and the same process (re-printing of the same document) or a new process (saving a printed document with a new file name) is performed for the object in the selected history data. The history number is provided for the history data, and a correlation is provided for the process that caused the process represented by the history data, and the history number of the process that is caused by the process represented by the history data. When a specific history number is designated for the search for the history data, it is employed to acquire the history number for the associated process, and the history data that has the acquired history number is also added to be object for a search.

Description: BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to an information processing apparatus for storing history data for operations and processing and for performing processing based on the history data, and a method therefor. Related Background Art As is shown in Fig. 1A, with an editing application, such as a word processor, the history data for operations (deletion, input and input in Fig. 1A) performed by a user in the past can be stored, so that the operation can be re-performed. Further, as is shown in Fig. 1B, in a Web browser application, address information for a home page that a user referred to in the past is stored as the history data for home pages (New product data, ABC Company home page and XYZ Development Division home page in Fig. 1B), so that a home page that was referred to in the past can be referred to again. An information processing apparatus called a personal computer (hereinafter referred to as a PC) handles electronic information. Therefore, physical information that exists in real space, such as a note that a person wrote or a printed document, is converted into electronic information by an input device, such as a scanner or a digital camera, in order for a PC to handle it. To enable a person to handle electronic information held in a PC, the electronic information must be converted into physical information by an output device, such as a printer or a display device. Assume here that the electronic information held in the PC is output to a printer. As is shown in Fig. 2, since data are printed via a server 22 by a printer 21, history data 24 can be stored in the server 22. The stored history data 24 can be referred to by a person in charge of system management. Since the printer 21 is controlled by the server 22, the server 22 must normally be operating. When data are printed via a server 25 by the printer 21, history data 27 are stored only in the server 25. Operations taking place along a route that the server 22 can not manage can not be stored in the server 22, so that history data 24 are managed by individual servers. Since the servers that can store history data are provided, the history data are stored in the individual servers, but data, which is transmitted from a PC 23 to the printer 21 directly without passing through the server 22, can not be retained as history data. Conventionally, only the minimum data required to refer to an operation in the past are stored as history data. Therefore, insufficient history data are available to initiate a new operation, and such an operation, supported only by history data, can not be performed. That is, the stored history data can not be effectively employed for anything other than the historical purposes, to confirm the performance of an operation in the past, and for the re-performance of an operation, and for an information processing apparatus other than the one that performed original operation, the history data is not utilized. Further, the contents of the information to be used for an operation are not stored as history data. Based on the idea that input/output devices are PC peripheral devices, the history data can not be handled by them, and the data are only stored in the PCs when the PCs physically control the input/output devices when performing processing. However, relative to the input/output of physical data, the input/output devices serve as contact points between a user and a PC, and when only the processes performed by the input/output devices under the control of the PC can be stored and used as history data, this is not only inconvenient for a user, but also it tends to discourage a potential user of the above described system. When an input/output device only is employed by or when it is used directly by individual PCs, the history data for the input/output device can not be stored. In order to record the history data, the input/output device must be connected to the server, and thus a great load is imposed on a server manager. In addition, since the management of all the input/output devices in a network domain under the control of a sever must be uniform, in order for a server to obtain all the history data, the load imposed on the server is increased, and is unbalanced. Further, while a server can not maintain the history data for an operation performed across a route that it can not manage, it is also impossible for the flow of data to various input/output devices to be controlled by only one server, and in this case, only incomplete history data can be handled. GB 2263988 discloses a work flow database in which records are stored upon instantiation, execution and termination of each step of a work flow. Output event signals are also logged. By storing data in this manner sufficient data is stored to enable a work flow to be recovered with little or no loss of the work that was accomplished prior to a system failure. It is, therefore, one objective of the present invention to provide an information processing apparatus that effectively uses history data for processes that are performed to enhance usability for a user, and a method therefor. It is another objective of the present invention to provide an information processing apparatus that effectively uses history data for operations that are entered and are performed to enhance usability for a user. According to one aspect, the present invention which achieves these objectives relates to an information processing apparatus comprising: input means for entering information; first output processing means for performing one of a plurality of types of output processing as a first output processing operation on the information entered at said input means; and storage means for storing history data for the first output processing operation performed by said first output processing means, characterised by: said storage means being adapted to store the type of the first output processing and output information which has been output by said first output processing means as history data; data selection means for selecting one of the history data from said storage means; output processing selection means for selecting one of a plurality of types of output processing which is different from the first output processing as a second output processing operation; and second output processing means for performing the second output processing operation on the output information contained in the history data selected by said data selection means. According to another aspect, the present invention provides an information processing method comprising: an input step of entering information; a first output processing step of performing one of a plurality of types of output processing as a first output processing operation on the information entered at said input step; and a storage step of storing history data for the first output processing operation performed at said first output processing step, characterised by: the type of the first output processing and output information which has been output in the first output processing is stored as history data at said storage step; a data selection step of selecting one of the history data stored at said storage step; an output processing selection step of selecting one of a plurality of types of output processing which is different from the first output processing as a second output processing operation; and a second output processing step of performing the second output processing operation on the output information contained in the history data selected at said data selection step.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The preferred embodiment of the present invention will now be described in detail while referring to the accompanying drawings. Fig. 3 is a diagram illustrating the hardware arrangement for the individual units that implement the processing according to this embodiment. An I/O 31 performs input/output with an external device. A CPU 32 executes a program and controls the individual sections. A ROM 33 is used to store constant data, and programs that are to be executed by the CPU 32 and correspond to the flowcharts, which will be described later. A RAM 34 is used to temporarily store a task table 44, which will be described while referring to Fig. 4, variables and intermediate data, such as operation data 42 and history data 49, that are generated during the processing. The program may be loaded into the RAM 34 from the outside. Fig. 4 is a diagram showing the functional arrangement according to the embodiment, and Fig. 8 is a diagram illustrating an example system arrangement. An information processing apparatus 1 in Fig. 4 is, for example, a printer 81 in Fig. 8, and an information processing apparatus 2 in Fig. 4 is, for example, a PC 82 or 83, or a telephone 84 that performs processing in association with the printer 81 in Fig. 8. In Fig. 8, an action initiated by the PC 82 or 83 or the telephone 84, which is an example for the information processing apparatus 2, the operation of a console unit 41, which will be described later, and the detection of the existence of the PC 82 are stored as history data 85 in the printer 81, which is one example of the information processing apparatus 1. The history data will be described later while referring to Fig. 7. The information processing apparatuses 1 and 2 can be any types of apparatuses so long as they possess the required functions for storing history data, and may be a printer, a scanner, a facsimile machine, a desktop PC, a filing server or a digital camera. In Fig. 4, the console unit 41 displays a screen required for a user in consonance with operation data 42. Information concerning data manipulation (operation), or an instruction entered by the user is transmitted to a task reception unit 43 and a history data management unit 48. In Fig. 8, assume that a user instructs the printer 81, which is one example for the information processing apparatus 1, to print file "abc.doc" stored in the PC 82, which is one example for the information processing apparatus 2. Information 707 in Fig. 7 is added to history data 49 by the history data management unit 48, and the history data 49 is transmitted to the task reception unit 34. In this embodiment, it is important that the individual input/output devices include the history data management unit 48 and the history data 49, and proper management be provided for these data. The operation data 42 is information or knowledge that is referred to by the console unit 41, and regulates the operation at the console unit 41. In this embodiment, based on data received by the task reception unit 43, the operation data 42 are changed or updated by a process execution unit 47, which will be described later, in order to implement flexible operating procedures. According to one of methods employed by the information processing apparatus 1 to control the information processing apparatus 2, the operation data 42 are acquired for the information processing apparatus 2, which changes or updates the operation data 42 of the information processing apparatus 1. In another example, the presence of the information processing apparatus 2, which is connected across a network to the information processing apparatus 1, is detected, and therefore, it is conformed that a new function can be obtained by combining the functions of the two information processing apparatuses. And necessary information for instructing the operation of the new function is added to the operation data 42, so that the function, which is a combination of the functions of a plurality of apparatuses, can be performed. The task reception unit 43 receives not only data from the console unit 41, but also, as a status change, receives changes effected in the environment of the information processing apparatus 1, and tasks from other apparatuses, such as the information processing apparatus 2. When the information processing apparatus is connected to a network, the reception task 43 also detects the connection of a new apparatus to the network, receives print instructions from other apparatuses as tasks, and detects a state wherein no process has been performed for a constant period of time. The task reception unit 43 adds received data as a new task to the task table 44, and also transmits it to the history data management unit 48. The task reception unit 43, as well as the process execution unit 47, which will be described later, is required for communication with a different apparatus. When, in Fig. 8, the PC 82, which is the information processing apparatus 2 connected via the network to the printer 81, which is the information processing apparatus 1, is powered on, the presence of the PC 82 is detected, and information 705 in Fig. 7 is added to the history data 49 by the history data management unit 48. Figs. 6A to 6F are diagrams showing an example task table 44. As is shown in Figs. 6A to 6F, in the task table 44 are entered the activation conditions and the contents of tasks, and a task having a history number is entered in the history data 49 for a process that is the source of the performance of individual tasks. In Figs. 6A to 6F, the tasks are arranged, beginning at the top of the table, in the order of priority. The addition of the task to the task table 44 is performed by the previously described task reception unit 43 and the process execution unit 47, which will be described later. The history number in the history data 49 of the process, which is the source for the performance of the tasks, is provided by the history data management unit 48. The extraction of the task from the task table 44 is performed by a task analyzer 45, which will be described later. ANALYZE in a task column 62 in the task table 44 in Fig. 6B is a task that is generated in response to the manipulation by a user [Print "abc.doc" from PC 82] at history No. 7, which is indicated by the history data 707 in a table for the history data 49 in Fig. 7. Thus, a value of "7" is stored in the Original history column, the activation condition is defined as no condition, and the contents of the task are defined as an analysis of the manipulation by the user. Since the task 62 is added as history No.8 to the history data 49, a value of "8" is set in the Original history for a task 63, which is generated based on the task 62, and similarly, a value of "9" is set in the Original history for a task 64. The task analyzer 45 extracts the highest priority task from the task table 44, and analyzes the purpose of the task. With this analysis, at a planning determination unit 46 and the process execution unit 47, which will be described later, the performance of less efficient operations is prevented, and an optimal process can be performed. For example, the task 63 stored in the task table 44 in Figs. 6A to 6F is analyzed as having a direct purpose of printing, and a final purpose is delivery of a printed document to a user. If the final purpose can be achieved by a more efficient method, it is understood that even the performance of printing may be unnecessary, and planning for the processing is performed in accordance with the analysis. The planning determination unit 46 receives the analysis from the task analyzer 45, and refers to the planning knowledge for the planning of a process to be performed to achieve the task. For the task 63 stored in the task table 44 in Fig. 6C, the operation Object: "abc.doc" = PULL from the PC 82 is planned before the object is printed. The process execution unit 47 performs the processing in consonance with the contents determined by the planning determination unit 46, and transmits the processing contents to the history data management unit 48. When the printing is executed, for example, information 711 in Fig. 7 is added to the history data 49 by the history data management unit 48. Upon the receipt of the instructions from the console unit 41, the task reception unit 43, or the process execution unit 47, in consonance with an operation performed by an operator, such as searching, editing, deleting, or condition/setup changing, the entry/reception of an instruction or information from another information processing apparatus, the detection of a status, and the performance of a process performed by the subject apparatus, such as reading, printing, displaying, transmitting, saving or holding of information, the history data management unit 48 adds to the history data 49, correlated the individual history data, information concerning an actor, such as an operator, an instructor or a person in charge of processing; information concerning an action that is executed, such as manipulation, an instruction or a process; information concerning time of manipulation, an instruction, or a process; information concerning a location or an apparatus whereat manipulation, an instruction or a process takes place; and information concerning an object that is manipulated, instructed or processed. Further, the history data management unit 48 outputs history numbers relative to the added history data. The data, added to the history data 49, for the object that is manipulated, instructed or processed are stored in correlation with data that are handled by another application, such as file data, schedule data, pending data for processing, a database (address list, etc.), data extracted from specific data or mail device management data, so that the employment of such data by individual applications is easy. The history condition designation operation, which is performed according to the instructions from the console unit 41, the task reception unit 34 and the process execution unit 47, can be used to determine whether history data corresponding to the operation, the instructions or the processing should be saved, and whether the substance of the object should be saved, and to designate a person who can refer to the history data. The data are added to the history data 49 according to the designations. In the history data usage process that is performed in accordance with the instructions from the console unit 41, the task reception unit 43 or the process execution unit 47, based on the history data 49 for the individual apparatuses that have been entered, the process is re-performed; a new process, such as printing, displaying, transmitting, saving, searching, action pending, editing or deleting, is performed for the past process; the setup for an alteration/saving condition for the period for saving history data is changed, or knowledge concerning the operation and the processing is updated. Fig. 7 is a diagram showing example history data 49. As is shown in Fig. 7, the history data 49 is composed of: a history No.; a Pre- history number, which is a history No. for history data for the process on which is based the generation of the processes represented by the individual history a Post-history number, which is the history No. for the history data for the process that is generated in response to the processes represented by the individual history ; an Execution time for the process represented by the history ; a Type of action; a Person for whom action is performed; an Object to be processed; and Other information, such as an action source, an action destination, and a location for the action. For example, [No = 7], in 707 in Fig. 7, designates 7 as the history number for the history data. Further, [preceding = head] indicates that the process represented by this history is a cue for a processing sequence, and constitutes the first process. [Succeeding = 8x] designates 8 as the history number for the process that is generated based on the process represented by the history [Time = 2/5 9:30:00] indicates that the process represented by the history was performed February 5, at 9:30:00. [Action = Operate] indicates that the process for this history is an operation. [Actor = Operator] indicates that an operator performed the process at this history [Object = "Print 'abc.doc' from PC 82"] indicates that the object of the process for the history is an instruction "Print 'abc.doc' from PC 82." [Others = Console unit 41] indicates that the process for this history was performed by the console unit 41. Fig. 5 is a flowchart showing the general processing according to this embodiment. When the information processing apparatus 1 is activated, at step S51 the task table 44 is initiated, as is shown in Fig. 6A. At step S52, a check is performed to determine whether the task reception unit 43 has received, as a status change, information concerning an instruction entered by a user at the console unit 41, an environmental change or a task from another apparatus. When a task is received, program control moves to step S53, whereat the reception of data is additionally recorded to the history data 49, as is shown by 704 in Fig. 7, and the reception data analysis task 62 is added at the beginning of the task table 44, as is shown in Fig. 6B. At step S54, a check is performed to determine whether there is an executable task in the task table 44. If there is no such task, program control returns to step S52, whereat the reception of a task is examined. When, at step S54, an executable task is present, program control advances to step S55, whereat the task having a highest priority is extracted from the task table 44. At step S56, the purpose of the task is analyzed, and at step S57, the process to be performed is determined and process planning is performed. If the task table 44 is as is shown in Fig. 6B, ANALYZE, which is the task 62 having the highest priority, is extracted, it is confirmed that the purpose of the task is analyzation of the received data, and planning for the processing for the initiation of analyzation is performed. At step S58, the processing is performed according to the plan, and a relevant record is added to the hysteresis data 49, as is shown by 710 in Fig. 7. A new task may be added to the task table 44, if necessary. When the received data are analyzed as planned for the ANALYZE task 62 in Fig. 6B, the instruction "Print 'abc.doc' from PC" entered by the user at the console unit 41 is analyzed, and PRINT, which is a new task 63, is added, as is shown in Fig. 6C. Program control returns to step S52. However, since a new task has not yet been received, program control moves to step S54 and the above process is repeated. As a result, PRINT for the task 63 in Fig. 6C, which was previously added at step S58, is extracted, analyzed and planned. In this case, to execute the PRINT task, it is confirmed that the Object is present in the information processing apparatus 1, and a new task 64, PULL, and a task 65, PRINT, that uses the pulled object are added as is shown in Fig. 6D. When the processing is further repeated, the task 64, PULL, in Fig. 6D is executed. When the processing is further repeated, the Object obtained as the result of the task PULL is used to execute the task 64 in Fig. 6E. As a result, the task table 44 is returned to the same state as when it was initialized, as is shown in Fig. 6F. The processing performed by the console unit 41 will now be described. Fig. 9 is a flowchart showing the processing performed by the console unit 41. Fig. 10 is a diagram illustrating an example screen displayed by the console unit 41. Fig. 11 is a diagram for explaining the operation of a system when a voice instruction is entered at the console unit 41. In consonance with manipulation by a user, the console unit 41 of the information processing apparatus 1 separately performs an operation that can be completed only by the process in the console unit 41, and the operation of the process must be performed via the task reception unit 43. For example, the process for changing a character string or a variable in the console unit 41, which corresponds to the entry/deletion of a character string in an input box 104 of a screen 103 in Fig. 10, is completed by the process performed inside the console unit 41. When actual printing can not be performed by the console unit 41 after a print button 105 has been selected, it is performed externally via the task reception unit 43. The processing performed by the console unit 41 will now be described while referring to the flowchart in Fig. 9. When the console unit 41 is activated, at step S901, the information defined in the operation data 42 is referred to in order to determine the operation procedures, including the contents of the display screen. At step S902 a check is performed to determine whether or not a user has actually performed an operation, such as the entry of a character string. If the user has not entered anything, the process at step S902 is repeated until the manipulation is performed. At step S903, the manipulation by the user is analyzed. When, at step S904, it is ascertained that the process has been completed only by the console unit 41, program control moves to step S905. When the process outside the console unit 41 is reacquired, program control goes to step S913. At step S905, a check is performed to determine whether the manipulation by the user is a designation for a history condition shown by 106 in Fig. 10. When an instruction is other than the designation of the history condition, program control moves to step S906. At step S906, if a process corresponds to the manipulation by the user, which is an action other than the designation of the history condition, the displayed character string is changed or the variable in the console unit 41 is updated. At step S907 the manipulation data are added to the history data in the console unit 41. When the history data in the console unit 41 are employed, the manipulation performed by the user can be canceled (UNDO) or repeated (REDO). Program control then returns to step S902 to accept an entry by the user. If, at step S905, the entry by the user concerns the designation of the history condition, program control goes to step S908, whereat the history condition designation unit performs the process. When the history condition designation unit is activated, at step S908 a check is performed to determine whether a manipulation was actually performed by the user, such as the input of a character string. If no manipulation was performed, the process at step S908 is repeated until a manipulation occurs. As step S909, the manipulation of the user is analyzed. When, at step S910, it is ascertained that the process was completed only by the history condition designation unit, program control moves to step S911. When the process outside the history condition designation unit is reacquired, program control goes to step S907. At step S911, in response to the manipulation by the user, the displayed character string is changed, or the variable in the history condition designation unit is updated. At step S912, the manipulation data is added to the history data in the history condition designation unit. Since the history data in the history condition designation unit is used, the manipulation by the user can be re-performed (UNDO) or repeated (REDO). Program control then returns to step S908 to accept the manipulation by the user. When, at step S902, the process outside the console unit 41 is required, program control moves to step S913, and whether or not saving of the history data is designated is determined by the previously described history condition designation unit, or by the standard setup by the user. As a result, when the saving of the history data is designated, program control goes to step S914. The contents of the manipulation are added to the history data 49, via the history data management unit 48, and the history number that is acquired is returned. The processing is thereafter terminated. Since the contents of the manipulation added to the history data 49 is employed as a cue for the processing that is to be performed, they are defined as being the first of the history data sequence when they are added. When the history data are actually added, the history number is returned from the history data management unit 48, and is then returned to the console unit 41. When there is no need to save the history data, an invalid value is returned as the history number. The processing is thereafter terminated. The specific processing performed by the console unit 41 will now be described while referring to the flowchart in Fig. 9 and the example display screen in Fig. 10. When the console unit 41 is activated, at step S901 the information defined for the operation data 42 is referred to in order to determine the operating procedures, and the screen 103 in Fig. 10 is displayed. In accordance with instructions on the screen 103, the user enters character string "Filing Server 102" in the input box 104 to designate the storage location of a document to be printed. At step S902 the entry of the character string is detected, and at step S903 the contents entered by the user are analyzed. At step S904, it is ascertained that the process can be completed only by the console unit 41, and at step S905 it is ascertained that the history condition designation has not been instructed. At step S906, in consonance with the character string that was entered, the display on the screen 103 is changed and the variable in the console unit 41 is updated. At step S907, the information that the character string is stored as history data in the console unit 41 is added. Since the history data for the console unit 41 is used, an input error can be corrected easily. When the user selects the history condition button 107 to instruct the designation of the history condition, a history condition designation screen 108.is displayed. In accordance with an instruction on the screen 108, the user enters a checkmark in the item "saving history " (white circle is changed to black). Then, at step S908 the occurrence of a specific manipulation is detected, and at step S909 the manipulation performed by the user is analyzed. As a result, at step S910 it is ascertained that the process can be completed only by the history condition designation unit. At step S907 in consonance with the manipulation by the user, the display on the screen 108 is changed, and the setup is changed to save the history. At step S912 the information that the setup has been changed is added to the history data of the history condition designation unit. When the history data is used, a manipulation error can be corrected easily. Similarly, whether the substance, which is the object to be processed, should be saved can be designated on the screen 108, and a specific user or a group member can be designated as a user who can refer to the history. When all the required conditions are designated by the above processing and the user selects a setup button 109 to instruct the validation of the designations. At step S910 it is ascertained that the process can not be completed only by the history condition designation unit, and program control moves to step S907, while the setup contents are validated. In the console unit 41, the file name, the print copy, the print range, and the necessary process to be executed are designated, as well as the storage location of the document to be printed. And when the user selects a print button 105 to instruct the performance of the process based on these designations, it is ascertained that the process can not be completed only by the console unit 41, and program control goes to step S913, whereat it is ascertained that the saving of the history data is designated. As a result, program control moves to step S914, and via the history data management unit 48, the manipulation contents are added to the history data 49, while they are defined as the first of the history data sequence, and the acquired history number is returned to the console unit 41. The processing is thereafter terminated. When the cancel button is selected, the operation performed is ineffective. To avoid a complicated explanation, no further explanation for this will be given. The specific processing performed by the console unit 41 when an instruction is entered by voice will now be described while referring to Fig. 11. Fig. 11 is a diagram showing an example where a file "abc.doc" is obtained from a filing server 112, which is an example information processing apparatus 1, via a printer 111, which is one example of the information processing apparatus 1, and is printed. First, the user gives the instruction orally "Print 'abc.doc' from Filing Server 112" to the printer 111, which is an example information processing apparatus 1, and at step S902 voice input is detected and at step S903 the instruction by the user is analyzed. If it is ascertained that the console unit 41 can not understand that the voice instruction, at step S904 it is ascertained the process can not be completed only by the console unit 41. Program control moves to step S913, whereat a check is performed to determine whether the recording of history data is designated. When, for example, the recording of history data is set as the standard, program control goes to step S914. Via the history data management unit 48, the manipulation contents are added to the history data 49 while they are defined as the first of the history data sequence, and the acquired history number is returned to the console unit 41. The processing is thereafter terminated. The voice instruction process is assigned to the task reception unit 43. The processing performed by the task reception unit 43 will now be explained. Fig. 12 is a flowchart showing the processing performed by the task reception unit 43. The task reception unit 43 of the information processing apparatus 1 handles, as reception tasks, all the information concerning the information processing apparatus 1, such as the contents of the manipulation by the user obtained by the console unit 41, and their history number, instructions and data received from the information processing apparatus 2, which is connected to the information processing apparatus 1 via the network, the external status information detected by the information processing apparatus 1, and the information concerning a document that is entered from the input section of the information processing apparatus 1. The task reception unit 43 separates a received task that can be completed only by the task recaption unit 43, and a received task that must be added to the task table 44 and performed outside the task reception unit 43. For example, the simple data exchange process according to the protocol, which corresponds to a task accompanied by basic communication, such as TCP/IP or HTTP, between the information processing apparatuses 1 and 2 connected via the network, can be completed only by the task reception unit 43. The process for the manipulation contents entered by the user at the console unit 41 and the history number, and the designation of the process from the information processing apparatus 2, which is connected to the information processing apparatus 1 via the network, can not be performed by the task reception unit 43. Thus, the task is added to the task table 44 so as to be performed outside the task reception unit 43. The specific processing performed by the task reception unit 43 will now be explained, while referring to the flowchart in Fig. 12. When the task reception unit 41 is activated, at step S121 a check is performed to determine whether a task has been received. If a task has not been received, the process at step S121 is repeated until one is received. At step S122 the received task is analyzed, and at step S123 a check is performed to determine whether the received task can be completed only by the task reception unit 43. If the task can be so completed, program control advances to step S124. At step S124 the process corresponding to the received task is performed, and a simple data exchange is also performed according to the protocol. At step S125 the received task information is added to the history data in the task reception unit 43. When the history data in the task reception unit 43 is used, the process can be canceled (UNDO) or repeated (REDO) in order to avoid a problem in the communication procedures due to noise. Then, program control returns to step S121 to accept a task. When, at step S123, it is ascertained that a process outside the task reception unit 43 is required, program control moves to step S126. A check is then performed to determine whether the saving of the history data has been designated by the history condition designation unit in the console unit 41, by a standard setup by the user, or by the setup of the reception task unit 43. When the saving of the history data is designated, program control advances to step S127, and a check is performed to determine whether the received task was received from the console unit 41. If the task is from the console unit 41, since the history is already added to the history data 49 by the console unit 41, addition of the history data is not performed. Program control thereafter moves to step S129. When, at step S127, the task has been received from a source other than the console unit 41, program control moves to step S128. The contents of the task are added to the history data 49 via the history data management unit 48, and the history number is acquired. Since the contents of the task added to the history data 49 are used to initiate the processing to be performed later, the task is defined as the first history data sequence. At step S129, the history numbers received from the console unit 41, or the history number returned from the history data management unit 48 when the history data are added at step S128, are set to the original history number of the task, and are added to the task table 44. When, at step S126, there is no need to save the history , an invalid value is set as the original history number for the task, and is added to the task table 44. The processing performed by the process execution unit 47 will now be described. In consonance with the contents of the processes to be performed, the process execution unit 7 of the information processing apparatus 1 separates the process that can be completed by the process execution unit 47, and a process that must be preformed outside the process execution unit 47, while adding a new task to the task table 44. The specific processing performed by the process execution unit 47 will now be described while referring to the flowchart in Fig. 13. When the process execution unit 47 is activated, at step S131 the contents of the process are analyzed, and at step S132 a check is performed to determine whether the process can be completed only by the process execution unit 47. If the process can be completed, program control advances to step S135. At step S133 the process according to the analyzed contents is performed, and at step S134 the contents of the process are added to the history data for the process execution unit 47. When the history data in the process execution unit 47 are used, the process can be canceled (UNDO) or repeated (REDO). Then, program control returns to step S131 to continue the remaining process. When the process can not be completed only by the process execution unit 47, at step S135 a check is performed to determine whether the original history number, which is designated for a task that corresponds to the process, is the valid original history number that designates the saving of the history . If the history number is valid, the history is saved, and if it is invalid, the history is not recorded. When the saving of history is ascertained, program control moves to step S136, whereat via the history data management unit 48, the contents of the process is added to the history data 49 and the history number is acquired. At step S137, when the history data are added at step S136, the history number referred from the history data management unit 48 is set as the original history number for the task, and is added to the task table 44. When at step S135 the saving of the history is not required, an invalid value is set as the original history number for the task, and is added to the task table 44. Since the above process contents regulate the execution of the results obtained by a specific process performed in the past, the number of the history data for the original process is also added. When the history data are added at step S135, therefore, the number of the history data for the original process must be acquired, and a new task should be added to the task table together with the number. The history data storage process performed by the history data management unit 48 will now be described. Fig. 14 is a flowchart showing the history data storage process. Figs. 15A and 15B are diagrams showing input/output data for the history data storage process. In the history storage process performed by the history data management unit 48 of the information processing apparatus 1, the manipulation, which was performed by a user in the past and which is represented by the history data, the instructions from another apparatus, and the status change and the process, which are performed by the information processing apparatus 1, are stored in correlation with each other. In this embodiment, as in the history data 49 in Fig. 7, a history number for the history data for the process, which is a cue for the processing represented by the individual history , is defined as a pre- history number. And the history is number for history data for the process, which is performed in response to the processes represented by the individual history , is defined as a post-history number. These numbers are entered in correlation with each other. In addition to the above described management method, inherent names are provided for the individual processes represented by the history data, and the names of the processes are stored in correlation with the history. Also the information corresponding to the names of the processes is stored, so that complicated management is possible. However, no detailed explanation for this method will be given. Data entered in the history data storage process are, as is shown in Fig. 15A, that entered by manipulation by a user with which the process that is to be added as history data is initiated, an instruction from another apparatus and a status change, on original history number 1501 to which the process performed by the information processing apparatus 1 is set, and an Action 1502 to which the contents of the actually executed process are set. For the manipulation performed by the user, the instruction from another apparatus and the status change, and the Action 1502 that represents the action effected by the information processing apparatus 1, there is more detailed information: Actor 1503 representing a person who acts, an Object 1504 representing an object to be processed, an Iobj 1505 representing an object destination for an action, a Reason 1506 representing the reason of an action, a From 1507 representing the source of an action, an Instrl 1508 representing tools and means for an action, a Support 1509 representing a location or an apparatus for an action, and a Time 1510 representing information concerning timing, such as the start, the end and the time period for an action. The data output in the history data storage process is a history number 1511 of the history data of the process to be added. The history data storage process will specifically be explained while referring to the flowchart in Fig. 14. When the history data storage process is initiated, at step S141 the original history number, which is transmitted as input data, is set for the pre-history number, and the information that represents the end of the related history data sequence is set for the post-history number. At step S142 the history data are added to the history data 49, and a new history number is acquired. At step S143 a check is performed to determine whether the original history number is the first information in the relating history data sequence. When the original number is not the first, program control moves to step S144, and when the original number is the first, the processing is thereafter terminated. Following this, the history data search process performed by the history data management unit 48 will be explained. Fig. 16 is a flowchart for the history data search process, and Figs. 17A and 17B are diagrams showing input/output data for the history search process. In the explanation for the history search process performed by the history data management unit 48 of the information processing apparatus 1, all the history data stored are regarded as search objects, and the process is performed by using the method for determining a search object employing a designated search condition. The data entered in the history search process are, as is shown in Fig. 17A, a history number 1701, which is designated to acquire history numbers of all the history data that are correlated with the process indicated by specific history data; and Action 1702, which is designated for the acquisition of a history number for history data that corresponds to the process performed by the information processing apparatus 1. For data entered by the user, the instruction from another apparatus and the status change, and an Action 1702 that represents the action effected by the information processing apparatus 1, there is more detailed information: an Actor 1703 representing a person who acts, an Object 1704 representing an object to be processed, an Iobj 1705 representing an object destination for an action, a Reason 1706 representing the reason for an action, a From 1707 representing the source of an action, an Instrl 1708 representing tools and means for an action, a Support 1709 representing a location or an apparatus for an action, and a Time 1710 representing information concerning timing, such as the start, the end and the time period for an action. The data output in the history data search process is, as is shown in Fig. 17B, search results 1711, including a history number 1712 for the history data that is searched for. The history search process will be specifically explained while referring to Fig. 16. When the history data search process is initiated, at step S161 all the history data 49 that are stored are set for the search result information in order to regard them as the search objects. At step S162 the search condition that is received as input data is employed to determine whether the effective history number has been designated. If the effective history number has been designated, program control advances to step S163. At step S163, all the history data indicated by the search result information are examined. The history data corresponding to the history number designated as the input data, and other history data that are designated by the pre-history number of the above history data, are examined until the pre-history number indicates the head, and all the associated history data are acquired. Similarly, the history data are examined until the post-history number indicates the end, and all the associated history data are acquired. Then, the search result information is updated. When, for example, the history data 49 in Fig. 7 are examined with history number = 9 being designated, history data for history number = 9 is acquired, and since the pre-history number of the history data with history number = 9 is 8, the history data at history number = 8 is acquired. In addition, since the pre-history number of the history data with history number = 8 is 7, the history data at history number = 7 is acquired. However, since the pre- history number of the history data with history number = 7 indicates the head of the associated history data sequence, data acquisition is no longer performed. The same process is performed for the post-history number, and history data with history number = 7 to 11 are stored as the search result information. At step S164, the search condition designated as the input data is examined to determine whether Action is designated. When the effective Action is designated, program control advances to step S165. At step S165, all the history data that are indicated as search objects in the search result information are examined, the history data that have Actions corresponding to the Action designated as input data are acquired, and the search result information is updated. When, for example, the history data 49 in Fig. 7 are examined with Action = Print being designated, the history data 709 and 711 in which Print is stored in Action are stored as search result information. To understand the above described embodiment more easily, as is shown by the history data 49 in Fig. 7, the history number of the history data for the process, which is the head of the processes indicated by the individual history data, is defined as the pre-history number, while the history number of the history data for the final process, which is the end of the processes indicated by the individual history data, is defined as the post-history number, and these numbers are correlated. Therefore, the history data 709 and 711 are detected as different processes. However, even though no detailed explanation will be given, inherent names are provided for the individual processes represented by the history data, the names of the processes correlating with the history are stored, and the information for the processes corresponding to their names are also stored, so that the history data 709 and 711 are detected as different expressions for the same process. At step S166, similarly, the search condition that is received as input data is examined to determine whether Actor has been designated. When the effective Actor has been designated, program control moves to step S167. At step S167, as well as the above described processing, all the history data designated as search objects in the search result information are examined. The history data corresponding to the Actor designated as the input data are acquired, and the search result information is updated. At step S168 and the following steps, the same process is performed for elements in addition to the Action, the object to be searched for is determined according to the search conditions that are designated in the input data, and the search result information is returned. The processing is thereafter terminated. Now, the history usage process performed by the process execution unit 47 will be described. Fig. 18 is a flowchart showing the history data usage process, and Fig. 19 is a diagram showing the relationship between the screen displayed in the history is data usage process, and another associated information processing apparatus. In Fig. 19, a printer 1901, which is an information processing apparatus 1, receives a search instruction from a user; examines the history stored for itself and the history for a scanner 2, which is the information processing apparatus 2, a display 1902, and a filing server 1910; and displays the search result on the panel of the printer 1901. In the history data usage process performed by the process execution unit 47 of the information processing apparatus 1, the result of the search for the history data 49 is displayed in accordance with an instruction from a user. When the performance of a specific process is designated relative to the history data designated by the user, in consonance with the contents of the instructed process, the printer 1901 separates the process that can be completed by only the history data usage processor, and the process for which a new task is added to the task table 44 and which must be performed outside the history data usage processor. The history data usage process will be specifically described while referring to Fig. 18. When the history data usage process is initiated, the display screen in Fig. 19 is displayed, and at step S1801 a check is performed to determine whether the user actually performed any entry manipulation, such as the entry of a character string. If no entry manipulation has occurred, the process at step S1801 is repeated until the entry manipulation by the user is performed. At step S1802, the entry manipulation performed by the user is analyzed, and at step S1803 program control branches to the process that corresponds to the contents of the entry manipulation. When the user instructs to a search for history data and the display of the search result, program control advances to step S1804; when the user instructs the performance of a specific process, program control moves to step S1807; and when the user instructs the ending of the history data usage process, the processing is terminated. At step S1804, the previously mentioned hjstory data search process is performed to search for the history data 49, and at step S1805 search results 1906 are displayed, as is shown in Fig. 19. At step S1806, the manipulation data are added to the history data in the history data usage processor. When the history data in the history data usage processor is used, the process can be canceled (UNDO) or repeated (REDO). Then, program control returns to step S1801 to accept an instruction from the user. When, at step S1803, it is ascertained that the performance of a specific process has been instructed, at step S1807 a check is performed to determine whether the instructed process can be completed by only the history data usage processor. For example, when a specific process is designated in a selection window 1908 in Fig. 19, it is ascertained that the process for displaying a screen 1909 to further specify the contents of the designated process can be completed by only the history data usage processor. Program control then moves to step S1808, whereat the process corresponding to the instruction is performed, and program control goes to step S1806. If, at step S1807, it is determined that the process is to be performed outside the history data usage processor, program control moves to step S1809. Although not shown in Fig. 18, to avoid a complicated drawing, a check is performed to determine whether the saving of history data is designated. When the saving of the history data is designated, the contents of the received task is added to the history data 49 by the history data management unit 48 and the history number is acquired. Since the contents of the task added to the history data 49 is a cue for the process to be executed later, this task is defined as the head of the history data sequence. At step S1810, when the history data are added at step S1809, the history number that is returned from the history data management unit 48 is set to the original history number for the task, and is added to the task table 44. When, at step S1809, the saving of the history data is not required, an invalid value is set as the original history number and is added to the task table 44. The processing is thereafter terminated. The history data usage process will be specifically described in detail while referring to Fig. 19. When the history data usage process is initiated, the operation display screen shown in Fig. 19 is displayed, and at step S1801, the entry from the user is accepted. When in consonance with the instruction on the screen, the user enters character string "operation" in the input box 1904 to designate search condition Action, at step S1801, the input of the character string is detected, and at step S1802, the entry by the user is analyzed. As a result, at steps S1803 and S1807, it is ascertained that the process designated by a user can be completed by only the history data usage processor. At step S1808 the. display on the screen is changed, and the variable in the history data usage processor is updated. At step S1806, information that the character string has been entered is added to the history data in the history data usage processor. When the history data for the history data usage processor is used, an input error can be corrected easily. When the search condition is designated by the above operation and the user selects a button 1905 to instruct a search, program control advances to step S1804, whereat the previously described history data search process is used to examine the history data 49. At step S1805, the search result 1906 is displayed. In addition, the user designates specific history data 1907 from among the displayed search results, and selects one of the processes in the selection window 1908: Re-process, Print, Display, Transmit, Save, Search, Pending, Edit, Delete, Condition change, and Others. When "Others" is selected, another selection window is displayed to select a change of a period of time for saving the history , a setup change, and an updating of information. In this embodiment, "Save" in the window 1908 is selected. Program control then moves to step S1808, whereat is displayed the designated process operation screen 1909 that corresponds to the selected "Save" process. On the operation screen 1909, storage location "Filing Server 1910", file name "new.doc" and saving range "2-8" are designated, and the "save" button is selected. Then, when the user instructs the execution of the process, at step S1807 it is determined that the designated process can not be completed by only the history data usage processor, and program control advances to step S1809. When the saving of the history data is designated, the contents of the operation are added to the history data 49 via the history data management unit 48, while the operation is defined as the head of the history data sequence. The history number is also acquired, and is set as the original history number and is added to the task table 44. The processing is thereafter terminated. The history data usage process upon receipt of an instruction by voice will be specifically described in detail, while referring to Fig. 20. When a user instructs the printer 201 by voice to "Save a document previously printed by Tom's printer as "new.doc" in Filing Server 202", at step S1801, the input of the voice is detected, and at step S1802 the contents of the instruction are analyzed. If it is ascertained that the history data usage processor can not understand the voice instruction, at step S1807 it is ascertained that the process can not be completed by only the history data usage processor. Thus, program control moves to step S1809. When the saving of history data is designated, in the history data management unit 48, the contents of the instruction are added to the history data 49, while they are defined as the first of the history data sequences, and the history number is acquired and is added to the task table 44 as the original history number. The processing is thereafter terminated. The added task is performed later, the history data 49 is searched for, as needed, and the "document previously printed by Tom's printer" is saved as the file name "new.doc" in the filing server 202. In the above described example, to understand this embodiment, the user employs the history data 49 via the screen. However, the history data 49 may be used by a task that is generated by the information processing apparatus 1, without waiting for the receipt of an instruction from the user. The history data 49 may also be used upon receipt of an instruction from the information processing apparatus 2, which is connected to the information processing apparatus 1 via the network. For example, in order to update the knowledge base of the planning determination unit 46 of the information processing apparatus 1, the apparatus 1 refers to the history data 49, including the entry manipulations performed by the user in the past, and analyzes the difference between the processes performed in the past in response to a specific instruction, so that the planning method for a specific instruction can be learned. According to the instructions from the information processing apparatuses 1 and 2 connected via the network, the history data 49 for all the information processing apparatuses that are connected to the network can be analyzed at one time. The present invention can be applied to a system that is constituted by a plurality of devices (e.g., a computer main body, an interface device and a display), or to an apparatus including a single device. The following is also included within the scope of the present invention: in order to operate various devices to implement functions in the above embodiment, software program code for implementing the functions in the previous embodiments are supplied to a computer in an apparatus, or in a system that is connected to various devices, and in consonance with the program, the computer (or a CPU or an MPU) in the system or the apparatus operates the devices to accomplish the functions in the above embodiments. In this case, the program code read from a memory medium accomplishes the functions of the above described embodiments. And the program code and means for supplying the program code to the computer, e.g., a memory medium on which such program code is recorded, constitute the present invention. A memory medium for supplying such program code can be, for example, a floppy disk, a hard disk, an optical disk, a magneto optical disk, a CD-ROM, a CD-R, a magnetic tape, a nonvolatile memory card, or a ROM. In addition, not only for a case where the functions in the previous embodiment can be performed when program code is read and executed by the computer, but also for a case where, according to an instruction in the program code, an OS (Operating System) running on the computer, or another application software program, interacts with the program code to accomplish the functions in the above embodiments, this program code can be included in the embodiments of the present invention. Furthermore, the present invention includes a case where program code, read from a memory medium, is written in a memory that is mounted on a function expansion board inserted into a computer, or in a function expansion unit connected to a computer, and in consonance with a program code instruction, a CPU mounted on the function expansion board or the function expansion unit performs one part, or all of the actual processing in order to implement the functions in the above described embodiments. When the present invention is applied for the above memory medium, program code corresponding to the previously described flowcharts is stored in the memory medium. As is described above, according to the embodiment, since the operation that was performed is stored as history data together with the associated data, the history data can be utilized more effectively than when the operation are stored merely as history data. When, for example, the history data are used not only for confirmation of the operation performed in the past or the re-performance of the operation, but also employed for another process or operation, so that efficiency in the process and usability can be drastically increased. Since the operation that was performed is stored as history data together with a person, timing, a location and an object concerning the performance of processing, the history data can be easily employed in the succeeding process. Further, since a series of operations that was performed is stored as history data with correlation each other, the correlation between the operations in the past and their definitions can be easily understood. In addition, since an object for another process and the history data are stored with correlation each other, the history data can be easily used in the other processes. Furthermore, since the storage condition for the history data can be designated, history data necessary for each operation can be stored. Moreover, since not only the history data of a subject apparatus but also the history data of another apparatus is employed, the processing efficiency and the usability can be improved. As a result, the effective usage of the history data is possible in an environment where a plurality of apparatuses are employed, and a user can seamlessly refer to and utilize the history data stored in each apparatus, without being aware of the difference among the apparatuses. The history data can be handled even in response to an operation, an instruction or a process that is not controlled by a PC, and the history data for an operation, an instruction or a process, for which an input/output device is required, can be stored, so that the usability can be drastically increased. Since the history data that should originally be handled by input/output devices can be stored in the corresponding input/output devices, the processing load imposed can be dispersed. Further, since the history data that are originally related to input/output devices are managed by the corresponding input/output devices, the completely prepared history data can be handled. In addition, since the object for the operation is stored as the history data, a new process can be performed for the operation object in the past.
