• the field 361 displays document data so as to be able to select each document data. In the operation window shown in Fig. 13, "specifications appendix B. doc" is selected.
• a check box 362 is used to designate document data to undergo batch processing.
• "specifications appendix B. doc" is designated as a target to undergo batch processing.
• a user switching key 363 is used to switch a user displayed in the pane. By pressing the user switching key 363, the owner of the pane displayed in the operation window can be switched.
• Keys 364 are used to execute various processes (jobs) . For example, when the key 364 for executing print processing is pressed in the operation window shown in Fig. 13, user "suzuki” who is the owner of the pane 323 serves as a job owner, and print processing (including batch processing) is executed. [0083] The operation of the image forming apparatus 1 when displaying an operation window with a single pane will be explained.
• Fig. 14 is a flowchart for explaining the operation of the image forming apparatus 1.
• step S1102 the control unit 50 detects that a user has logged in to the image forming apparatus 1.
• the embodiment explains the operation on the premise that a user logs in to the image forming apparatus 1. In practice, it is detected whether a user has logged in to the image forming apparatus 1.
• step S1104 the control unit 50 displays, on the liquid crystal display of the operation unit 30, information (e.g., the user information 321a in the operation window shown in Fig. 6) of the user detected in step S1102 to have logged in.
• step S1106 the control unit 50 displays, on the liquid crystal display of the operation unit 30, a logout key (e.g., the logout key 322 in the operation window shown in Fig. 6) for allowing the user, who is detected in step S1102 to have logged in, to log out.
• the liquid crystal display of the operation unit 30 displays the operation window shown in Fig. 6.
• the control unit 50 monitors whether a job key (e.g., one of the job keys 304 to 310 in the operation window shown in Fig.
• step S1108 If the control unit 50 determines in step S1108 that neither a job key nor shortcut key has been pressed, it keeps monitoring until a job key or shortcut key is pressed. If the control unit 50 determines in step S1108 that a job key or shortcut key has been pressed, the process advances to step S1110. [0090] In step S1110, the control unit 50 prepares for display of information (e.g., the field 358 for displaying user information in the operation window shown in Fig. 13) of the user who has logged in to the image forming apparatus 1.
• information e.g., the field 358 for displaying user information in the operation window shown in Fig. 13
• step S1112 the control unit 50 prepares for display of a login key (e.g., the "another user” key 359 in the operation window shown in Fig. 13) for allowing a user who has not logged in to the image forming apparatus 1 to log in.
• a login key e.g., the "another user” key 359 in the operation window shown in Fig. 13
• step S1114 the control unit 50 displays, on the liquid crystal display of the operation unit 30, an operation window of a single pane including the user information and login key prepared in steps SlIlO and S1112.
• step S1116 the control unit 50 monitors whether a key for executing a job (e.g., the key 364 for executing various processes in the operation window shown in Fig. 13) has been pressed.
• a key for executing a job e.g., the key 364 for executing various processes in the operation window shown in Fig. 13
• step S1116 determines in step S1116 that a key for executing a job has not been pressed, it keeps monitoring until a key for executing a job is pressed. If the control unit 50 determines in step S1116 that a key for executing a job has been pressed, the process advances to step S1118. [0096] In step S1118, the control unit 50 controls the reader unit 10, printer unit 20, storage unit 40, and the like to execute a job corresponding to the key determined in step S1116 to have been pressed. [0097] In step S1120, the control unit 50 acquires, based on an operation on the operation unit 30, information of a user (job owner) who has executed the job.
• step S1122 based on the job owner information acquired in step S1120, the control unit 50 rewrites a table (see Fig. 2) which is stored in the storage unit 40 and manages counter information for charging.
• step S1124 based on the job execution result in step S1118 and the job owner information acquired in step S1120, the control unit 50 rewrites a table (see Fig. 3) which is stored in the storage unit 40 and manages job log information.
