Furthermore, the storage unit 80 stores a control program used in the multifunction machine 1, data used by the control program, and the like.
The storage unit 80 includes a history management unit 81 and an output information management unit 82.

Each time the terminal device 200 uses the multifunction device 1, the history management unit 81 stores the work history in association with the used terminal device 200. For example, as illustrated in FIG. 4, the history management unit 81 stores the work history in association with the unique identification number that identifies the terminal device 200. As the work history, the history output is stored in addition to the work contents such as printing, FAX transmission, and FAX reception, the work time, and the file name of the work object. Here, in the case where an output request (to be described later) is received, the multifunction device 1 outputs only an arbitrary work history without outputting all of the work history, and determines whether or not to output the work history. Managed by history output. The arbitrary work history may be set in advance or may be set by the user. Also, it may be possible to set whether or not to output a work history in response to an output request for each work content (that is, for each usage history). Whether or not to output may be settable. In this embodiment, it is assumed that the work history is set to be output for each work content (that is, for each usage history), the work history is output for printing and FAX transmission, and the work history is output for FAX reception. do not do.
In addition, there may be a plurality of users in each of a plurality of business operators sharing one office environment. Therefore, the history management unit 81 may define group information so that it can be grasped that it belongs to the same business. At this time, the history management unit 81 may define the terminal device 200 (or user) that permits output of the work history for each group information.

  Returning to FIG. 3, the output information management unit 82 temporarily stores the output information output from the multifunction device 1 in response to a use request from the terminal device 200. The output information is output information (for example, a printer description language for printing) generated from a print target file or a FAX target file, and is information read into the multi-function device 1 when output from the multi-function device 1. is there. In the present embodiment, as shown in FIG. 5, the contents of work, the presence / absence of output, the work time, the contents of the work target file, etc. are associated with the unique identification number that identifies the terminal device 200 that has requested use. Is stored as output information. In addition, although illustration is abbreviate | omitted, group information is prescribed | regulated similarly to work history, and it is good also as managing output information for every provider.

  Returning to FIG. 3, a communication network NW (see FIG. 1) is connected to the interface unit 100. Input from the terminal device 200 is supplied to the control unit 90 via the interface unit 100.

The control unit 90 controls the document conveying unit 10, the document reading unit 20, the engine unit 3, the operation unit 70, and the like.
The control unit 90 includes a storage control unit 91, an authentication unit 92, a reading unit 93, an output control unit 94, and an erasing unit 95.

  The storage control unit 91 performs control for storing various types of information in the storage unit 80 in accordance with an input from the terminal device 200. For example, when receiving a usage request from the terminal device 200, the storage control unit 91 generates output information from the target file, and associates the generated output information with the time when the usage request is received, for example, as an output information management unit 82. Memorize temporarily. When the storage control unit 91 receives a use request from the terminal device 200, the storage control unit 91 stores a work history indicating the work content and the like in the history management unit 81. That is, the storage control unit 91 updates various information stored in the history management unit 81 and the output information management unit 82 in response to a use request from the terminal device 200.

  When the user makes a work history output request via the terminal device 200, the authentication unit 92 authenticates whether or not the terminal device (or user) is permitted to output the work history. By such authentication, it is possible to permit the output of the work history only to a limited user among a plurality of users belonging to the same business operator.

  When receiving the output request, the reading unit 93 reads the work history of the terminal device 200 corresponding to the output request from the history management unit 81. At this time, the reading unit 93 may read the output information that has not been output from the output information management unit 82 when the operation of the terminal device 200 includes an operation that has not been output.

The output control unit 94 outputs the work history and output information read by the reading unit 93 in response to a work history output request. Here, in this embodiment, the output request for the work history includes an output request that is automatically made when a predetermined date and time is reached, in addition to an output request from the terminal device 200 (that is, an output instruction by the user). It is. The work history output request includes an output request for a plurality of terminal devices 200 (that is, in units of business operators) in addition to an output request for one terminal device 200.
Further, as the output of the work history and the like, in addition to printing the image such as the work history on the paper T by controlling the engine unit 3, the work history and the like are transmitted to the predetermined terminal device 200. Including. Note that the predetermined terminal device 200 may be the terminal device 200 that has made an output request, or may be a terminal device 200 that is set in advance regardless of whether or not an output request has been made. At this time, when the work history or the like is transmitted to the preset terminal device 200, the work history or the like is transmitted on condition that the terminal device 200 is connected to the communication network NW, and the terminal device 200 is transmitted. Is not connected to the communication network NW, it is preferable not to transmit or print the work history or the like. This can reliably prevent the work history from being output to a third party. When the destination terminal device 200 is not connected to the communication network NW, the destination terminal device 200 is not connected. Connect the terminal device. A message prompting connection of the terminal device 200 may be output. The output of the message may be displayed on a display unit (not shown) of the multifunction device 1 or may be transmitted to the terminal device 200 that has made the output request.

  The output control unit 94 may output a part of the work history instead of all the work histories stored in the history management unit 81. As a part of the work history to be output, a work history set as history output “◯ (see FIG. 4)” in the history management unit 81 can be adopted. In this embodiment, for example, printing and FAX transmission are possible. The usage history for FAX reception corresponds to the work history that is not output.

  The erasure unit 95 erases the work history of the terminal device 200 corresponding to the output request from the history management unit 81 on condition that the work history is output by the output control unit 94. At this time, it is preferable that the deletion unit 95 deletes the output information from the output information management unit 82 in addition to the work history of the terminal device 200 corresponding to the output request. Note that the erasure unit 95 erases all of the work history corresponding to the output request regardless of whether or not the output control unit 94 has output. In other words, the erasure unit 95 also erases the history of use for FAX reception that is not output by the output control unit 94.

  Next, the operation of the multifunction machine 1 in this embodiment will be described. FIG. 6 is a flowchart for explaining the operation of the multifunction device 1, and FIG. 7 is a flowchart for explaining the output processing (step ST3) of FIG. 6 in detail.

  In step ST <b> 1, the output control unit 94 determines whether a work history output request has been received from the user via the terminal device 200. If a work history output request has been received (YES), the process proceeds to step ST2, and if a work history output request has not been received (NO), the process proceeds to step ST4.

  In step ST <b> 2, the authentication unit 92 determines whether or not the terminal device 200 that has issued the output request in step ST <b> 1 is the terminal device 200 that is permitted to output the work history. If the terminal device 200 is permitted to output the work history, the process proceeds to step ST3. If the terminal device 200 is not permitted, the process ends.

  In step ST3, the output control unit 94 performs an output process described later with reference to FIG.

  In step ST4, the output control unit 94 determines whether it is the date and time when the work history is output. The date and time when the work history is output can be set as appropriate. For example, the time immediately before the end of the use time of the shared office environment can be set. If it is the date and time when the work history is output (YES), the process proceeds to an output process (step ST3) described later in FIG. 7, and if it is not the date and time when the work history is output (NO), the process is ,finish.

  Next, step ST3 will be described in detail with reference to FIG. In step ST31, the output control unit 94 specifies the terminal device 200 that outputs the work history. For example, when an output request is made in units of business operators, the output control unit 94 identifies a plurality of terminal devices 200 as terminal devices 200 that output work histories.

  In step ST32, the reading unit 93 reads the work history of the terminal device 200 specified in step ST31 from the history management unit 81.

  In step ST32, the reading unit 93 determines whether there is unoutput output information among the output information of the terminal device 200 specified in step ST31. If there is output information that has not been output (YES), after the reading unit 93 reads the output information from the output information management unit 82, the process proceeds to step ST34, and there is no output information that has not been output (NO). In that case, the process proceeds to step ST35.

  In step ST34, the output control unit 94 outputs the work history of the terminal device 200 specified in step ST31 and the output information that has not been output. Note that the output control unit 94 may output the work history and unoutputted output information by different methods. That is, the work history may be transmitted to the terminal device 200, while the output information that has not been output may be output (printing, FAX transmission, or the like) according to the work content.

  In step ST35, the output control unit 94 outputs the work history of the terminal device 200 specified in step ST31.

  In step ST36, the erasure unit 95 erases various information of the terminal device 200 that has output the work history in step ST34 or step ST35 from the storage unit 80. For example, the erasure unit 95 erases the work history stored in the history management unit 81 and the output information stored in the output information management unit 82.

As described above, according to the multifunction machine 1 of the present embodiment, the following effects are achieved.
That is, upon receiving a predetermined request, the multifunction device 1 of the present embodiment not only simply deletes the work history of the terminal device 200 stored in the multifunction device 1 but also outputs this work history to the user. . As a result, it is possible to prevent other operators sharing the office environment from grasping their work history, and the user can look back on the work performed by the user and ensure that the work is performed. I can grasp it.

  The multifunction device 1 also outputs output information that has not been output when the work history is output. As a result, it is possible to prevent unoutput output information from being stored in the multifunction device 1 and to prevent information from being leaked to other business operators.

  Further, the multifunction device 1 outputs and deletes a work history and the like when a preset date and time comes. As a result, when the usage time of the shared office environment ends, the work history and the like can be automatically output and deleted, and security can be improved.

  In addition, the multifunction device 1 outputs and deletes the work history and the like on condition that a predetermined user makes an output request via the terminal device 200. Thereby, the user can manage the output and deletion of the work history and the like. In addition, since the output and deletion of the work history and the like are limited to some users (terminal device 200), security can be improved.

  Further, when outputting the work history, the multifunction machine 1 may not output the work history of the work depending on the content of the work. Thereby, the user does not need to confirm useless work, and can easily grasp the work contents.
