Tomoyuki Ozu, “Displaying RSS-delivered article titles in an electric bulletin board style” Dirty News Reader ”, [Online], May 26, 2004, Impression Corporation, [Search July 29, 2008], Internet, <http://www.forest.impress.co.jp/article/2004/05/26/dirtynewsreader.html>

  A method of always displaying the title of the content in the processing execution device can be considered. However, this method is not preferable from the viewpoint of energy saving because the title of the content is displayed even while the user is not using the processing execution device.

  The present specification discloses a technique capable of saving energy in a processing execution apparatus that displays a title of content.

  The technology disclosed in this specification is a process execution device that executes a process according to a process execution instruction. The “process execution device” is a concept including all devices that execute a process when a process execution instruction is input from a user. As an example of the processing execution device, a printer, a scanner, a copier, a facsimile, a multi-function device, and the like can be given. The processing execution apparatus includes position information storage means, summary information acquisition means, instruction input means, display means, and display control means. Each of these means will be described in detail below.

  The location information storage means can store location information of content summary information including at least a title of each content. The term “location information” is a concept including any information that can specify the location of the content summary information. As an example of the position information, for example, a URL (Uniform Resource Locator) can be cited. The “content” may be text data or other types of data (image data, music data, video data). The summary information acquisition means acquires content summary information from the position information stored in the position information storage means. The instruction input means inputs a process execution instruction. For example, the instruction input unit may be an interface connected to a network. In this case, the instruction input means inputs a process execution instruction sent from the network. Further, for example, the instruction input unit may be an operation unit that allows the user to operate. In this case, the instruction input means inputs a process execution instruction according to the user's operation. The contents of the process instructed by the “process execution instruction” are not particularly limited. Examples of the process execution instruction include a print instruction, a copy instruction, a scan instruction, a communication instruction (for example, FAX transmission instruction), a display process, and the like.

  The display control means includes a first state in which the title of each content included in the content summary information acquired by the summary information acquisition means is displayed on the display means, a second state in which the title of each content is not displayed on the display means, It is possible to switch between the first state and the third state in which power is saved compared to the second state and the title of each content is not displayed on the display means. Note that the display control means may switch the display of the display means between four or more states including other states.

  The display control means shifts to the first state when a process execution instruction is input in the instruction input means in the second state or the third state, and the first condition determined in advance in the first state is When the condition is satisfied, the state is shifted to the second state, and when the second condition predetermined in the second state is satisfied, the state is shifted to the third state. As an example of the above-mentioned “predetermined first condition” and “predetermined second condition”, a predetermined time has elapsed since the start of the display of the title of each content, and the user instructs the display to stop Can be input to the processing execution device. The first condition and the second condition may be the same condition or different conditions.

  The process execution device described above can realize the first state in which the title of each content is displayed when a process execution instruction is input. In a situation where a process execution instruction is input, there is a high possibility that the user exists in the vicinity of the process execution device (or the user may approach the process execution device). The title of each content can be displayed in a situation where there is a high possibility that the user can see the title of each content. When a predetermined first condition is satisfied when the title of each content is displayed, the display unit shifts to the second state, and the display of the title of each content is stopped. Since the title of each content is not always displayed, it is superior in terms of energy saving as compared to the method of always displaying the title of each content. In addition, when the second condition that is determined in advance when the second state is displayed, the display unit shifts from the second state to the third state where power is saved. For this reason, energy consumption can be further suppressed. A method of shifting to the second state when a processing execution instruction is input during the third state is also conceivable. However, in this case, there is a high possibility that the user can see the title of each content. Regardless, the title of each content is not displayed. When a process execution instruction is input during the third state, the content state title can be provided to a user in the vicinity of the process execution device by shifting to the first state. This processing execution apparatus can provide the title of each content to the user while realizing energy saving.

  The processing execution device may be connected to a network so as to be communicable. Further, the location information storage means may be capable of storing a plurality of combination information in which device specifying information for specifying devices constituting the network and location information of the content summary information are associated with each other. The above “device specifying information” is a concept including any information that can specify a device. As an example of the device identification information, an IP address, a MAC address, a node name, a user name, a host name, and the like can be given. In addition, the “combination information” is not limited to the case where the device identification information and the position information of the content summary information are associated one-to-one. A plurality of device specifying information may be associated with one position information. Conversely, a plurality of pieces of position information may be associated with one piece of device specifying information. Further, the summary information acquisition unit may be able to acquire content summary information from each piece of position information stored in the position information storage unit. The instruction input means may be capable of inputting a first process execution instruction output from the network. The contents of the process instructed by the “first process execution instruction” are not particularly limited. Examples of the first process execution instruction include a print instruction, a scan instruction, a communication instruction (for example, a FAX transmission instruction), a display process, and the like. Further, the first process execution instruction may include output source device identification information.

The content update date / time information 142 is information related to the date / time when the content is updated in the content providing server (latest update date / time). The content summary character string 144 is a summary of character strings included in the content. In other words, the content summary character string 144 is a character string that is more than the title of the content, less than the entire character string of the content, and is a character string that reflects the contents of the content. The content URL 146 is a content URL.

(Processing executed by PC)
Subsequently, processing executed by the PC 70 will be described. The PC 71 performs the same processing. The user can input an instruction for causing the multi-function device 10 to perform printing on the PC 70 by operating the operation unit 84 of the PC 70. When this instruction is input, the CPU 72 of the PC 70 transmits a print instruction including the IP address of the PC 70 to the multi-function device 10.

(Feed information analysis process executed by multi-function device)
Next, feed information analysis processing executed by the multi-function device 10 will be described. The feed information analysis process operates as an independent task, and is executed from the time of activation of the multi-function device 10 according to the Internet connection program 20 and the feed information analysis program 22 (see FIG. 2). FIG. 5 shows a flowchart of the feed information analysis process.

  The CPU 14 waits until the update time is reached (S40). The update time may be set by a user or may be determined by a program, for example. When the update time is reached, the process proceeds to S42.

  In S42, the CPU 14 acquires each URL 100 from the URL storage area 44 (see FIG. 3) of the NVRAM 40 (S42). Next, the CPU 14 accesses the URL acquired in S42 according to the Internet connection program 20, and acquires feed information (S50). The feed information includes site information 120 and updated content information 132 shown in FIG. The CPU 14 creates the display information 112 shown in FIG. 4 by analyzing the feed information (S52). The CPU 14 stores the display information 112 created in S52 in the display information storage area 36 (S54). For example, when the new display information 112 of the site corresponding to the URL “http://www.example0.com” associated with the user X is created, the CPU 14 clears the old display information 112 and adds a new one. Display information 112 is stored. When the CPU 14 obtains the feed information from all the URLs 100 stored in the URL storage area 44 and creates the display information 112, the process returns to S40. By executing the processing shown in FIG. 5, the latest feed information of each site is stored in the display information storage area 36.

(Display state of the multi-function device)
Next, a plurality of states in the display panel 50 of the multi-function device 10 will be described. FIG. 6 is a diagram for explaining how a plurality of states change. FIG. 10 shows an example of the display panel 50 corresponding to each state. As shown in FIG. 6, the multi-function device 10 has a plurality of states including a power saving state 170, a standby state 174, a function execution state 178, and the like. In the power saving state 170, nothing is displayed on the display panel 50 as shown in the uppermost diagram of FIG. 10 (the backlight of the display panel 50 is turned off). For this reason, the power saving state 170 is a power saving compared to the other states 174 and 178. When a function execution instruction (for example, a print instruction, a scan instruction, etc.) is input during the power saving state 170, the function transitions to the function execution state 178. In the function execution state 178, the content title character string 162 is displayed on the display panel 50 as shown in the second diagram from the top in FIG. Further, information on the function being executed (characters “printing” in the example of FIG. 10) is displayed on the display panel 50. When the function being executed ends, as shown in the second diagram from the bottom of FIG. 10, the display of information regarding the function being executed is stopped. Hereinafter, the state in the second diagram from the bottom in FIG. 10 is referred to as an “intermediate state”. In the intermediate state, information 160 for selecting a function is displayed and a content title character string 162 is displayed. When the feed information end timer exceeds the time limit in the intermediate state, the process shifts to the standby state 174. In the standby state 174, as shown in the lowermost diagram of FIG. 10, the content title character string 162 is not displayed, and only the information 160 for selecting a function is displayed. For this reason, the standby state 174 (the lowermost diagram in FIG. 10) saves power compared to the intermediate state and the function execution state 178. The user can input a function execution instruction to the multi-function device 10 by operating the information 160.

  When the power saving state transition timer exceeds the time limit during the standby state 174, the state shifts to the power saving state 170. In the power saving state 170, nothing is displayed on the display panel 50 as shown in the top diagram of FIG. 10 (the backlight of the display panel 50 is turned off). Therefore, the power saving state 170 is power saving compared to the function execution state 178, the intermediate state, and the standby state 174. When a function execution instruction is input during the power saving state 170, the standby state 174, or the intermediate state, the state shifts to the function execution state 178. Note that another function execution instruction may be input during the function execution state 178. In this case, the function execution state 178 is continued.

(Display processing executed by the multi-function device)
Next, a display process for displaying the feed information by the CPU 14 of the multi-function device 10 will be described. The display process operates as an independent task, and is executed from the time of activation of the multi-function device 10 according to the feed information display program 24 (see FIG. 2). FIG. 7 shows a flowchart of the display process.

  In S <b> 70, the CPU 14 stands by until an instruction is input in the power saving state 170. The user can touch the display panel 50 or operate the keypad 52 in the power saving state 170. In this case, the process proceeds to S72. Further, the user can output a print instruction from the PCs 70 and 71 to the multi-function device 10. Also when the print instruction is input, the process proceeds to S72. When any instruction is input in S70, the CPU 14 displays the content shown in the lowermost diagram of FIG. In S72, the CPU 14 performs a user specifying process (S72). The contents of the user specifying process will be described in detail next.

(User-specific processing)
FIG. 9 shows a flowchart of the user specifying process. The CPU 14 determines whether or not a scan function execution instruction has been input (S112). The user can operate the Scan button 160 shown in FIG. Furthermore, the user can designate PC identification information (IP address or host name) as an output destination of scan data by operating the keypad 52. In this case, YES is determined in S112. If YES in S112, the CPU 14 identifies the user name associated with the PC identification information of the scan data output destination from the default PC information storage area 46 (see FIG. 2) (S116). When S116 ends, the process proceeds to S74 in FIG.

  If NO in S112, the CPU 14 determines whether or not a print instruction including print data has been input (S114). If YES here, the process proceeds to S118. As described above, the print instruction includes PC identification information from which the print instruction is output. The CPU 14 specifies PC identification information included in the print instruction. Next, the CPU 14 specifies the user name associated with the PC identification information specified here from the default PC information storage area 46 (see FIG. 2) (S118). When S118 ends, the process proceeds to S74 in FIG.

  An instruction that cannot specify the user (an instruction other than a scan function execution instruction or a print instruction) may be input to the multi-function device 10. In this case, the CPU 14 determines NO in S114, and proceeds to S74 in FIG.

  In S74 of FIG. 7, the CPU 14 initializes a feed information end timer (S74). The feed information end timer is a timer that counts the elapsed time for stopping the display of the content title character string 162. Next, the CPU 14 acquires the display information 112 associated with the user name (for example, “X”) specified in the user specifying process of FIG. 9 from the display information storage area 36 of the RAM 30 (S78). Note that the user name may not be specified in the user specifying process in S72 (in the case of NO in S114 of FIG. 9). In this case, the CPU 14 acquires the first display information 112 stored in the display information storage area 36 in S78.

  Subsequently, the CPU 14 specifies the number of update content information 132 included in the display information 112 acquired in S78 (S80). For example, in the case of the display information 112 associated with the user name “X”, there are m contents in the example of FIG. In this case, the CPU 14 specifies “m” in S80. Next, the CPU 14 initializes the counter j (S82). Next, the CPU 14 determines whether or not the counter j is smaller than m (S86). If YES here, the process proceeds to S92.

  In S92, the CPU 14 acquires the j-th updated content information from the display information 112 specified in S78. Thereby, the content title character string 140, the content update date / time information 142, the content summary character string 144, and the content URL 146 of one content are acquired (S92). Next, the CPU 14 transmits the content title character string 140 acquired in S92 and the content update date / time information 142 acquired in S92 to the display panel 50 (S94). As a result, the content title character string 162 is displayed on the display panel 50 as shown in FIG. The content title character string 162 moves (for example, moves from right to left). That is, the content title character string 162 is displayed in a telop shape. The site title character string 122, the content update date / time information 142, the content summary character string 144, and the like may or may not be displayed on the display panel 50. A summary display screen may be provided to switch the display. Further, the site title character string 122 and the feed update date / time information 124 included in the site information 120 may be displayed on the display panel 50 or may not be displayed. When S94 ends, the process proceeds to S96 in FIG.

  In S96 of FIG. 8, the CPU 14 waits until an event occurs. If an event occurs, the process proceeds to S98. In S98, the CPU 14 determines whether or not the telop display of the content title character string 162 has ended. In the case of YES here, the CPU 14 adds 1 to the counter j (S100), and proceeds to S101. In S101, the CPU 14 determines whether or not the feed information end timer initialized in S74 (or S106 described later) exceeds the time limit. If NO here, the process returns to S86 in FIG. In S86, the CPU 14 determines whether or not the counter j is smaller than m. If YES is determined here, the CPU 14 executes S92 and S94 again. As a result, the content title character string 162 is displayed in telop on the basis of the next update content information (for example, the first update content information).

  If YES in S101 of FIG. 8, the process proceeds to S103. In S103, the CPU 14 ends the display of the content title character string 162. As a result, only the information 160 is displayed on the display panel 50 as shown in the lowermost diagram of FIG. Subsequently, the CPU 14 initializes a power saving state transition timer (S105). Next, the CPU 14 determines whether or not any instruction (operation of information 160, operation of the keypad 52, printing instruction, etc.) is input from the user (S107). In the case of YES here, the CPU 14 returns to S72 and executes the user specifying process. On the other hand, in the case of NO in S107, the CPU 14 determines whether or not the power saving state transition timer initialized in S105 has exceeded the time limit (S109). In the case of YES here, the CPU 14 turns off the backlight of the display panel 50 and shifts to the power saving state 170 (S110). Next, the process returns to S70 and waits until an instruction is input.

  If NO in S98 of FIG. 8, the process proceeds to S99. In S99, the CPU 14 executes a user specifying process shown in FIG. When the user identification process ends, the CPU 14 proceeds to S102. In S102, the CPU 14 determines whether or not an instruction (in this embodiment, a print execution instruction or a scan execution instruction) that can specify a user is input in the user specifying process executed in S99. If YES here, the process proceeds to S108. In S108, the CPU 14 determines whether or not the user name specified in the user specifying process executed in S99 is the same as the user name associated with the display information 112 in which the content title character string 162 is currently displayed. Is determined (S108). If YES here, the CPU 14 initializes the feed information end timer (S106), returns to S96 and waits until an event occurs. That is, if the user name is the same, the display information 112 (content title character string 162) associated with the user name is continuously displayed. On the other hand, if NO in S108, the CPU 14 returns to S74 in FIG. 7 to initialize the feed information end timer. In this case, the CPU 14 acquires the display information 112 associated with the user name specified in S102 (S78), and starts displaying the content title character string 162 based on the display information 112 (S94). ).

  If NO in S102 of FIG. 8, the process proceeds to S104. In S104, the CPU 14 determines whether or not the function (printing or scanning in the present embodiment) that can identify the user has finished the operation. In the case of YES here, the CPU 14 initializes the feed information end timer (S106), returns to S96 and waits until an event occurs. On the other hand, if NO in S104, the CPU 14 executes processing corresponding to the event, returns to S96, and waits until the next event occurs. In the flowchart of FIG. 8, when NO in S98, an instruction that cannot specify the user (for example, operation of the keypad 52) is not monitored, but when such an instruction is input, The CPU 14 may initialize the feed information end timer and return to S96.

  The multi-function device system 2 of the present embodiment has been described in detail. The multi-function device 10 can display the content title character string 162 of each content. The content title character string 162 of each content can be provided to the user. The multi-function device 10 stops displaying the content title character string 162 when the feed information end timer exceeds the time limit. Since the content title character string 162 is not always displayed, the content title character string 162 is superior in terms of energy saving as compared with the method of always displaying the content title character string 162. The multi-function device 10 turns off the backlight of the display panel 50 when the power saving state transition timer exceeds the time limit. For this reason, power consumption can be further saved. According to the multi-function device 10, the content title character string 162 can be provided to the user while realizing energy saving.

  Further, the multi-function device 10 receives, for example, an instruction to execute a scan function with the PC 71 as an output destination of scan data while the content title character string 162 is displayed based on a print instruction output from the PC 70, for example. In the case (NO in S108 of FIG. 8), the content title character string 162 included in the site feed information registered by the user of the PC 71 can be displayed. On the other hand, the multi-function device 10 receives an instruction to execute a scan function with the same PC 70 as an output destination of scan data while the content title character string 162 is displayed based on a print instruction transmitted from the PC 70, for example. If it has been done (YES in S108 of FIG. 8), the content title character string 162 can be continuously displayed. In this technique, when a print instruction is input while the content title character string 162 is displayed based on the print instruction, printing is performed while the content title character string 162 is displayed based on the scan function execution instruction. This is also used in the same manner when an instruction is input and when an instruction for executing a scan function is input while the content title character string 162 is displayed based on the instruction for executing the scan function.
