Description:
BACKGROUND OF THE INVENTION 
     The present application claims priority on Japanese Patent Application No. 2010-267386, filed Nov. 30, 2010, the content of which is incorporated herein by reference. 
     FIELD OF THE INVENTION 
     The present invention relates to an image forming apparatus and an image forming system. 
     DESCRIPTION OF THE RELATED ART 
     In recent years, informational data including images and letters are transmitted using a communication network such as an internet. A technology is utilized such that a displaying device displays an information based on the transmitted informational data. This displaying device may display the same information such as television and newspapers. In addition, the displaying device may switch over information according to the place at which the displaying device is installed, and according to time zone. Therefore, the display device may display information in an effective manner to a particular target audience. Furthermore, the display device may be switched over easily as an informational data stored in a transmission source (transmission server) is updated. Therefore, the process of switching over the display device is not cumbersome. 
     A method to output information as described above is to display information on the displaying device. Another method to output information is to make a multi functional peripheral such as an image forming apparatus print out the information. For example, at retail outlets such as convenience stores and the like, an image forming apparatus and a server (information processing device) are installed. This information processing device stores informational data transmitted from the transmission server. When the image forming apparatus receives an output instruction, the image forming apparatus forms an image of the informational data to a blank space of a paper on which an output image is already attached, or, to a back side of the paper. 
     However, according to the conventional technology described above, when an image forming apparatus forms an image of a piece of information in a continuous manner, there is a problem in that a preparation of the informational data does not catch up. Therefore, a waiting time occurs for the image formation on each sheet of paper. Moreover, it takes time for the image formation of the information to be completed. In this way, since it takes time for the image forming apparatus to complete the image formation, a user often must wait for a long period of time. 
     The present invention is made according to the considerations described above. An object of the present invention is to shorten the time spent on forming an image. 
     SUMMARY OF THE INVENTION 
     In order to achieve the above object, the present invention employs the following. 
     Namely, an image forming apparatus according to an aspect of the present invention includes: an operation unit receiving an operation instruction; an image forming unit performing an image formation; a control unit making the image forming unit perform an image formation when the operation unit receives an image formation instruction; a data acquisition unit obtaining an image formation object data; a data conversion unit converting the image formation object data to an image formation format data; and a plurality of memory regions storing the image formation format data. Here, when the data acquisition unit obtains the image formation object data, the control unit makes the data conversion unit convert the image formation object data to the image formation format data. In addition, the control unit makes each of the plurality of memory regions store each of the image formation format data. When the operation unit receives an image formation instruction, the control unit makes the image forming unit perform an image formation, in a predetermined order, of the image formation format data stored in the plurality of memory regions. 
     In addition, an image forming system according to an aspect of the present invention includes: an information processing device; and an image forming device communicating with the image processing device and including a plurality of memory regions storing an image formation format data. Here, when the information processing device obtains an image formation object data, the information processing device converts the image formation object data to the image formation format data and outputs the image formation format data to the image forming device. In addition, when the image forming device obtains the image formation format data from the information processing device, the image forming device makes each of the plurality of memory regions store each of the image formation format data. When the image forming device receives an image formation instruction, the image forming device performs an image formation, in a predetermined order, of the image formation format data stored in the plurality of memory regions. 
     EFFECT OF THE INVENTION 
     According to the present invention, a method of storing an image formation format data individually to each of a plurality of memory regions, a method of making a conversion to a first image formation format data based on an image formation target data and making a conversion to a second image formation format data based on a portion of an image formation target data, and a method of storing a fixed image formation format data in advance to a second memory region, are executed in combination or in a singular form. As a result, it is possible to reduce the amount of time spent to form an image.

     A communication connection is established between the information processing device C and the multi functional peripheral A, and between the information processing device C and the displaying device B. Furthermore, a communication connection is established between the information processing device C and the transmission server D via the transmission network E. The information processing device C stores information data (image formation target data) received from the transmission server D. Furthermore, the information processing device C makes the multi functional peripheral A perform an image formation based on the informational data. In addition, the information processing device C may be a computer which makes the displaying device B display information. 
     The transmission server D is a server installed to transmit informational data in a PDF format, a JPEG format, and the like. The transmission server D is connected via the transmission network E to the information processing device C and another information processing device (not shown). The informational data is updated as needed. The transmission server D transmits the informational data to the information processing device C and the other information processing device. 
     Examples of the transmission network E include a local area network and a public internet. The transmission network E connects the information processing device C and the transmission server D. In this way, the transmission network E serves as a signal transmission path of the transmission between the information processing device C and the transmission server D. 
     Next, a configuration of a multi functional peripheral A of the image formation system S is described with reference to  FIG. 2 . 
     As shown in  FIG. 2 , the multi functional peripheral A includes an operation displaying unit (operation unit)  1 , an image reading unit  2 , a data memory unit  3 , a data processing unit (data conversion unit)  4 , a paper transporting/image formation unit (image formation unit)  5 , a transmission unit (data acquisition unit)  6 , and a main control unit (control unit)  7 . 
     The operation displaying unit  1  includes an operation key  11  and a touch panel  12 .

In addition, the operation displaying unit  1  outputs the operational instruction to the main control unit  7 . Further, the operation displaying unit  1  displays various screens on the touch panel  12  based on a command signal of the main control unit  7 . 
     The image reading part  2  uses a line sensor to perform a reading of an image (draft image) of a draft, automatically supplied by an automatic draft feeding device A 1 , or an image (draft image) of a draft placed on a platen glass. The image reading part  2  performs the reading based on a control signal inputted by the main control part  7 . Further, the image reading unit  2  converts the draft image that it read into a draft image data. Moreover, the image reading unit  2  outputs this draft image data to the data memory unit  3 . 
     Examples of the data memory unit  3  include a semiconductor memory or a hard disk device. Examples of data stored by the data memory unit  3  include a draft image data based on a command signal inputted from the main control unit  7 , a PDL (Page Description Language) format data inputted from the image processing device C, a first bit map image data or a bit map image data of an image formation format (image formation format data or a first image formation format data) converted from a PDL format data at a data processing unit  4  described later, a text data inputted from the information processing device C, a second bit map image data (a second image formation format data) converted from the text data at the data processing unit  4 , a fixed bit map image data (fixed image formation format data), and the like. The data memory unit  3  reads out these data, and outputs these data to the data processing unit  4 . 
     As shown in  FIG. 3 , a first folder  31 ,  32 , and a second folder  33  are provided in the data memory unit  3 . The first folder  31 ,  32  store a first bit map image data (or a bit map image data) or a second bit map image data, and the like. The first bit map image data (or a bit map image data) and the second bit map image data are each converted from one informational data. Further, a fixed bit map image data is stored in advance in the second folder  33 . 
     The data processing unit  4  performs various image processing operations (for instance, an image process according to an enlargement or a shrinkage copying) on the draft image data inputted from the data memory unit  3 . The data processing unit  4  performs the various image processing operations based on a control signal inputted from the main control unit  7 . At the same time, the data processing unit  4  converts the draft image data to a bit map image data with an image processing format. In other words, the data processing unit  4  converts an RGB image data (color image data) according to the three primary colors of light to an YMCK image data having a standard color of Y (yellow), M (magenta), C (cyan), and K (black). Further, the data processing unit  4  outputs this YMCK image data to the paper transporting/image formation unit  5 . In addition, the data processing unit  4  converts the text data and the PDL format data inputted from the data memory unit  3  to a bit map image data of an image formation format based on a control signal inputted from the main control unit  7 . Moreover, the data processing unit  4  outputs this bit map image data to the paper transporting/image formation unit  5 . 
     The paper transporting/image formation unit  5  includes a print engine (a photoconductive drum, an electrostatically charged apparatus, a developing apparatus, a fixing roller, and the like), a paper feeding roller, a paper ejecting roller, and the like. The paper transporting/image formation unit  5  transports a recording paper from a sheet feeding cassette (not shown) based on a control signal of the main control unit  7 . Further, the paper transporting/image formation unit  5  performs an image formation on a recording paper based on the bit map image data inputted from the data processing unit  4 . Then, the paper transporting/image formation unit  5  ejects this recording paper to a paper ejecting tray (not shown). 
     The transmission unit  6  is connected to the information processing device C via a transmission cable. The transmission unit  6  performs a transmission with the information processing device C based on a control signal of the main control unit  7 . 
     The main control unit  7  includes a CPU (Central Processing Unit), an ROM (Read Only Memory), an RAM (Random Access Memory), and an interface circuit which performs an input and output of the operation displaying unit  1 , the image reading unit  2 , the data memory unit  3 , the data processing unit  4 , the paper transporting/image formation unit  5 , and the transmission unit  6 . The main control unit  7  controls the entire operation of the multi functional peripheral A according to a control program stored in the ROM and an operation instruction inputted from the operation displaying unit  1 . Incidentally, the control program stored in the ROM includes an image formation control program. The main control unit  7  controls an image forming operation based on the image formation control program. 
     Next, a configuration of the information processing device C is described with reference to  FIG. 2 . 
     As shown in  FIG. 2 , the information processing device C includes a transmission unit  21 , a data memory unit  22 , a data processing unit  23 , and a main control unit  24 . 
     The transmission unit  21  is connected to the multi functional peripheral A via a transmission cable. At the same time, the transmission unit  21  is connected to the transmission server D via the transmission network E. The transmission unit  21  communicates with the multi functional peripheral A and the transmission server D based on a control signal of the main control unit  24 . 
     Examples of the data memory unit  22  include a semiconductor memory and a hard disc device. The data memory unit  22  stores informational data obtained by the transmission unit  21  from the transmission server. Further, the data memory unit  22  reads out this informational data and outputs the informational data to the data processing unit  23 . Further, the data memory unit  22  stores the PDL format data and the text data, which were converted by the data processing unit  23  described later. Moreover, the data memory unit  22  reads out this PDL format data and the text data, and outputs the informational data to the transmission unit  21 . 
     The data processing unit  23  converts the informational data inputted from the data memory unit  22  into a PDL format data based on a control signal inputted from the main control unit  24 . At the same time, the data processing unit  23  converts only the letter information in the informational data into text data. At this time, the data processing unit  23  makes a conversion into PDL format data after making a conversion to text data based on informational data. 
     The main control unit  24  includes a CPU (Central Processing Unit), an ROM (Read Only Memory), an RAM (Random Access Memory), and an interface circuit and the like performing an input and output of a signal with the transmission unit  21 , the data memory unit  22 , and the data processing unit  23 . The main control unit  24  controls the entire operation of the information processing device C according to a control program stored in the ROM. Incidentally, the control program stored in the ROM includes a PDL format data controlling program. The main control unit  24  controls the conversion processing of the PDL format data and the output processing of the PDL format data based on this PDL format data controlling program. 
     Next, an operation of the multi functional peripheral A and the information processing device C according to the image forming system S is described with reference to  FIG. 4 . 
     According to the information processing device C, when the transmission unit  21  obtains informational data from the transmission server D via the transmission network E, the main control unit  24  makes the data memory unit  22  store informational data (step S 1 ). After step S 1 , the main control unit  24  makes the data processing unit  23  convert the informational data to a PDL format data (step S 2 ). After step S 2 , the main control unit  24  makes the transmission unit  21  output the PDL format data to the multi functional peripheral A (step S 3 ). 
     According to the multi functional peripheral A, when the transmission unit  6  obtains a PDL format data from the information processing device C, the main control unit  7  makes the data processing unit  4  convert each of a plurality of PDL format data to a bit map image data. Further, the main control unit  7  stores each of the bit map image data to each of the first folders  31 ,  32  (step S 4 ). 
     After step S 4 , when the operation displaying unit  1  receives an output instruction (image formation instruction), the main control unit  7  makes the paper transporting/image formation unit  5  perform an image formation according to a predetermined sequence on a bit map image data stored in a plurality of the first folders  31 ,  32  (step S 5 ). 
     In addition, when the operation display unit  1  receives an additional informational output instruction, the main control unit  7  makes the paper transporting/image formation unit  5  form a normal copied image on a front surface of a recording paper. At the same time, the main control unit  7  makes the paper transporting/image formation unit  5  form an image of the information on a back surface of the recording paper. 
     Next, a variation of an operation shown in  FIG. 4  is described with reference to  FIG. 5 . 
     According to the information processing device C, when the transmission unit  21  receives an informational data from the transmission server D via the transmission network E, the main control unit  24  makes the data memory unit  22  store the informational data (step S 11 ). After step S 11 , the main control unit  24  makes the data processing unit  23  perform a conversion to text data based on the informational data, and, thereafter, perform a conversion to PDL format data (step S 12 ). After step S 12 , the main control unit  24  makes the transmission unit  21  output the text data and the PDL format data in series to the multi functional peripheral A (step S 13 ). 
     According to the multi functional peripheral A, when the transmission unit  6  receives text data from the information processing device C, the main control unit  7  makes the data processing unit  4  convert the text data to the second bit map image data. When the transmission unit  6  obtains PDL format data from the information processing device C, the main control unit  7  makes the data processing unit  4  convert the PDL format data to a first bit map image data. Further, the main control unit  7  makes the first folder  31  store a combination of the second bit map image data and the first bit map image data (when there are a plurality of combinations, store each of the combinations to each of the first folders  31 ,  32 ) (step S 14 ). At this time, the text data is outputted from the information processing device C faster than the PDL format data. As a result, the text data is first converted to the bit map image data. In other words, compared to the first bit map image data, the second bit map image data is stored to the first folder  31 . 
     After step S 14 , when the operation displaying unit receives an output instruction (image formation instruction), the main control unit  7  makes the paper transporting/image formation unit  5  perform an image formation based on the first bit map image data stored in the first folder  31 . When only the second bit map image data is stored in the first folder  31 , i.e., when a PDL format data is not yet obtained from the image processing device C, or when a conversion is not yet made to the first bit map image data, the main control unit  7  makes the paper transporting/image formation unit  5  perform an image formation based on this second bit map image data (step S 15 ). Furthermore, when the operation displaying unit receives the additional information output instruction, the main control unit  7  makes the paper transporting/image formation unit  5  form a normal copying image on a front surface of a recording paper. At the same time, the main control unit  7  makes the paper transporting/image formation unit  5  form an image of the information on a back surface of the recording paper. 
     Next, a variation of the operation shown in  FIG. 4  above is described with reference to  FIG. 6 . 
     According to the information processing device C, when the transmission unit  21  receives an informational data from the transmission server D via the transmission network E, the main control unit  24  makes the data memory unit  22  store the informational data (step S 21 ). After step S 21 , the main control unit  24  makes the data processing unit  23  convert the informational data to PDL format data (step S 22 ). After step S 22 , the main control unit  24  makes the transmission unit  21  output the PDL format data to the multi functional peripheral A (step S 23 ). 
     According to the multi functional peripheral A, when the transmission unit  6  receives PDL format data from the information processing device C, the main control unit  7  makes the data processing unit  4  convert the PDL format data to a bit map image data. Further, the main control unit  7  makes the first folder  31  store the bit map image data (when there are a plurality of bit map image data, each of the bit map image data is stored to each of the first folders  31 ,  32 ) (step S 24 ). 
     After step S 24 , when the operation displaying unit receives an output instruction (image formation instruction), the main control unit  7  makes the paper transporting/image formation unit  5  perform an image formation based on the bit map image data stored in the first folder  31 . When a bit map image data is not stored in the first folder  31 , i.e., when a PDL format data is not yet obtained from the image processing device C, or when a conversion is not yet made to the bit map image data, the main control unit  7  makes the paper transporting/image formation unit  5  perform an image formation based on a fixed bit map image data stored in the second folder  33  (step S 25 ). Furthermore, when the operation displaying unit receives the additional information output instruction, the main control unit  7  makes the paper transporting/image formation unit  5  form a normal copying image on a front surface of a recording paper. At the same time, the main control unit  7  makes the paper transporting/image formation unit  5  form an image of the information on a back surface of the recording paper. 
     As described above, according to an image forming system S based on an embodiment of the present invention, a method of storing each of a plurality of bit map image data (image formation format data) to each of a plurality of first folders  31 ,  32  (see  FIG. 4 ), a method of making a conversion to a second bit map image data (second image formation format data) based on an informational data based on a first bit map image data (first image formation format data) and a portion of the informational data (see  FIG. 5 ), and a method of storing a fixed bit map image data (fixed image formation format data) to a second folder  33  in advance (see  FIG. 6 ) may be each used to reduce the amount of time spent to form an image. 
     A preferable embodiment of the present invention has been described above. However, the present invention is not limited by the above embodiment. Components and configurations may be added, omitted, replaced, and other alterations may be made within the gist of the present invention. For example, the following variations are possible. 
     (1) In the embodiment described above, the multi functional peripheral A stored the bit map image data. However, the present invention is not limited to this configuration. 
     The multi functional peripheral A may be configured so that a PDL format data obtained by the information processing device C is not converted to a bit map image data. Instead, the PDL format data may be stored in its original PDL format as an image formation format data (or a first image formation data). When an output instruction is received, the PDL format data may be converted to a bit map image data (or a first bit map image data). Thus, an image formation may be performed based on this bit map image data (or a first bit map image data). 
     Alternatively, the multi functional peripheral A may be configured so that the text data obtained from the information processing unit C is not converted to a second bit map image data. Instead, the text data is stored in its original form as a second image formation format data. When an output instruction is received, the text data may be converted to the second bit map image data. An image formation may be performed based on this second bit map image data. 
     Moreover, according to the present embodiment, the information processing device C converts informational data to a PDL format data. Meanwhile, the multi functional peripheral A converts the PDL format data to the bit map image data. However, the present invention is not limited to this configuration. A configuration may be made so that the information processing device C is installed inside the multi functional peripheral A. According to this alternate configuration, the multi functional peripheral A obtains informational data from the transmission server D. This informational data is converted to a bit map image data (or a PDL format data). This bit map image data (or the PDL format data) is stored. When an output instruction is received, an image formation may be performed based on the bit map image data (or a bit map image data converted from the PDL format data). In addition, the information processing device C may be configured so that, when informational data is obtained from the transmission server D, this informational data is converted to a bit map image data, and this bit map image data is outputted to the multi functional peripheral A. 
     (2) According to the above embodiment, informational data is obtained from the transmission server D. However, the present invention is not limited by this configuration. For example, informational data may be obtained from an external memory medium such as a USB memory. 
     (3) According to the above embodiment, a method of storing each of a plurality of bit map image data (image formation format data) to each of a plurality of first folders  31 ,  32  (see  FIG. 4 ), a method of making a conversion to a second bit map image data (second image formation format data) based on an informational data based on a first bit map image data (first image formation format data) and a portion of the informational data (see  FIG. 5 ), and a method of storing a fixed bit map image data (fixed image formation format data) to a second folder  33  in advance (see  FIG. 6 ) are each used in its singular form. However, the present invention is not limited to this configuration. Each of the methods may be combined in various ways. 
     The present invention is not limited by the embodiments described above. The present invention is instead limited by the attached claims.
