## Background
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to an image reading apparatus a non-transitory computer-readable recording medium for converting image data obtained by reading an original by a scanner and transferring the data.
Description of Related Art
There is a multi function peripheral for charging a user for the copy of an original or the like. For example, there is an image processing apparatus which checks whether a user inserts money which is not less than a charge fee necessary for executing all processes designated by the user, and which starts the processes in case that it is confirmed that the money which is not less than the necessary charge fee is inserted (See Japanese Patent Application Publication No. 2009-111592).
Among multi function peripherals to which an external recording medium, such as a USB (Universal Serial Bus) memory or the like, is detachably attached, there is a multi function peripheral for executing a job for converting the image data obtained by reading an original by a scanner into the data having the designated format as a file, and for storing the file in a USB memory (Scan To USB job). In case that an original having a plurality of sheets is processed in accordance with the above job, in general, as shown in the process method A of FIG. 6, by executing the process for converting the image data of the read pages and for transferring the file generated by converting the image data to a USB memory in parallel with the operation for reading the original, the whole process time is shortened.
In case of the Scan To USB job, because the charge fee is calculated according to the number of sheets of the original, the image size, color/monochrome, or the like, the charge fee cannot be decided until the whole original have been read. Therefore, when the process is executed by using the process method A shown in FIG. 6, the file is transferred to a USB memory without confirming that the necessary charge fee is paid. A wrong action in which the USB memory is withdrawn without paying the necessary charge fee, cannot be prevented.
In view of the above problem, the following process method B is considered. In the process method B, the charge fee is decided by reading the whole original and the image data obtained by reading the original are temporarily stored in the image processing apparatus. After it is confirmed that the money which is not less than the decided charge fee is inserted, the image data stored in the image processing apparatus are converted and the data are transferred to the USB memory. In the process method B, because the image conversion and the data transfer are started after the reading of the original is finished, the whole process time is longer than that of the process method A.
For example, it is assumed that the job for reading the original having fifty sheets to convert the image data of the original and for transferring the data to the USB memory is executed in accordance with the process method B shown in FIG. 6. In this case, the process time for converting the image data of one sheet of an original having A4 size into the data as a file having the PDF (Portable Document Format) format is 1 second, the file size of the data for one sheet of the original is 50 KB, the transfer speed of the data to the USB memory is 30 MB/s, and the reading time for reading the original having fifty sheets by the scanner is 80 seconds. The whole process time is calculated by the equation: the reading time (80 seconds)+ the image conversion time (1 second×50 sheets)+ the transfer time (1 second)=131 seconds.
In case that the process method A shown in FIG. 6 is used, the reading of the original and the image conversion/data transfer are executed in parallel. Therefore, the whole process time for the job is only the reading time (80 seconds)+alpha. As described above, when the process method B is adopted in order to charge the fee, in case of the reading of 50 sheets, the whole process time is about 50 seconds longer than that of the process method A.
Not only in case that the data are stored in a USB memory, but also, for example, in case that a user is charged for the job for transmitting the file obtained by the image conversion to an external terminal via the network, the above problem is caused. Further, in addition to the case in which the charge fee is paid, for example, in case that the upper limit of the number of the sheets which can be used by each user or in each section of a company is managed, the above problem is caused.

FIG. 2 is a block diagram showing the electric schematic configuration of the image reading apparatus 10. The image reading apparatus 10 comprises a CPU (Central Processing Unit) 11 as a control unit for entirely controlling the operation of the image reading apparatus 10. The CPU 11 is connected with a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a nonvolatile memory 14, a hard disk drive 15, an auto document feeder (ADF) 16, a network communication unit 17, an image reading unit 18, an image processing unit 19, a printer unit 21, a facsimile communication unit 22, a connecting unit 23, a vender I/F (Interface) unit 24, an operation panel 30, and the like, via a bus.

The auto document feeder 16 has the function for conveying the original by feeding the original set to the original setting tray from the top sheet one by one, passing the original through the reading position of the image reading unit 18 and discharging the original to a predetermined discharge position. The image reading unit 18 has the function for reading the original set on a platen glass, and has the function for sequentially reading the original which is conveyed by the auto document feeder 16.
The image processing unit 19 executes the rasterization process for converting print data into image data, the compression/decompression process for the image data, the process for converting the image data into the data having the predetermined format, and the like in addition to the processings, such as the enlargement/reduction and the rotation of image data. That is, the image processing unit 19 has the function as the image conversion unit for converting the image data into the data having the predetermined format.
The printer unit 21 has the function for forming an image on the recording sheet in accordance with the image data. In this embodiment, the printer unit 21 is configured as a so-called laser printer which comprises a conveying device for the recording sheet, a photoconductive drum, a charging device, a laser unit, a developing device, a transfer and separation device, a cleaning device and a fixing device, and which forms an image by the electrophotographic process.

The display unit 31 comprises a liquid crystal display (LCD), the driver thereof, and the like. The operating unit 32 comprises various types of hardware keys, such as a start button, a numeric keypad, and the like, a touch panel provided on the display screen of the display unit 31, and the like. The touch panel detects the coordinate position on which the display screen of the display unit 31 is contacted by a touch pen, the user's finger or the like to operate the image reading apparatus 10.
Next, the operation in which the image reading apparatus 10 executes a Scan To USB job for reading an original by using a scanner, converting the image data obtained by the reading of the original into the data having the format designated by a user (in this embodiment, the data having the designated format (for example, PDF)) and transferring the data obtained by converting the image data to a USB memory which is connected with the connecting unit 23, to store the data in the USB memory, will be explained.
FIG. 3 is a flowchart showing the whole process for executing the Scan To USB job by the image reading apparatus 10. In the image reading apparatus 10, the CPU 11 executes the following process by reading the programs stored in the ROM 12. When the image reading apparatus 10 receives the instruction for executing the Scan To USB job, the CPU 11 judges whether the charging mode is set or not (Step S101). In case that the charging mode is not set (Step S101; No), the image reading apparatus 10 executes the Scan To USB job by the process method A shown in FIG. 6 (Step S103).
In detail, the original set to the auto document feeder 16 is sequentially read by the image reading unit 18. In parallel with this operation, the image reading apparatus 10 executes the image conversion process for converting the image data obtained by the reading of the original into the data having the format designated by a user, and the transfer process for transferring the data obtained by the image conversion to the USB memory connected with the connecting unit 23 to store the data in the USB memory. That is, by carrying out the setting relating to the charging mode, an administrator or the like can select whether the CPU 11 (the judgment unit) executes the judgment process for judging whether the above transfer process can be executed. In case that the CPU 11 (the judgment unit) does not execute the above judgment process, the CPU 11 (the executing unit) instructs the image reading apparatus 10 to transfer the data output from the image processing unit 19 or the like to the USB memory without using the hard disk drive 15 or the like.
In case that the charging mode is set (Step S101; Yes), the image reading apparatus 10 executes the Scan To USB job by the process method C shown in FIG. 6 (Step S102). In the process method C, the original set to the auto document feeder 16 is sequentially read by the image reading unit 18 and in parallel with this operation, the image reading apparatus 10 executes the image conversion process and stores the data obtained by the image conversion in the temporary area of the image reading apparatus 10. The temporary area is provided in the RAM 13 or the hard disk drive 15.
When the reading of the whole original set to the auto document feeder 16 is finished, the CPU 11 (the judgment unit) judges whether the data can be transferred to the USB memory (the destination). In this embodiment, CPU 11 executes the charge check in order to execute the above judgment process depending on whether the necessary charge fee is paid. Then, in case that the data can be transferred, the CPU 11 (the executing unit) instructs each unit of the image reading apparatus 10 to execute the process for transferring the data obtained by the image conversion to the USB memory and storing the data. That is, in the process method C, the CPU 11 (the executing unit) instructs each of the image reading apparatus 10 to execute the process for converting the image data obtained by reading the original and for storing the data in the temporary area regardless of whether it is judged that the data can be transferred in the charge check. After it is judged that the data can be transferred, the CPU 11 (the executing unit) instructs each unit of the image reading apparatus 10 to execute the process for transferring the data obtained by the image conversion to the USB memory.
Therefore, in the process method C, it is possible to prevent the data obtained by the image conversion from being transferred to the user's USB memory in the situation in which the charge fee is not paid. Further, because the reading of the image and the image conversion are executed in parallel, it is possible to shorten the whole process time as compared with the process method B.
Next, the process in which the Scan To USB job is executed by the process method C will be explained. The process method C includes the first mode in which the transfer of the data which are judged as the transferable data is executed after the image conversion for the whole original is finished, and the second mode in which the transfer route is switched while the image conversion is executed.
FIG. 4 shows the process for executing the Scan To USB job in accordance with the first mode of the process method C. Firstly, the CPU 11 checks whether the money is inserted in the charging vender device 5 (Step S201). Because the charge fee is not decided until the reading of the original is finished, the amount of money inserted at this time may be the predetermined minimum amount (for example, one cent) or more.
In case that the money is inserted (Step S201; Yes), the reading of the original is started (Step S202). Further, in parallel, the image conversion and the process for storing the data obtained by the image conversion in the temporary area are started (Step S203). Specifically, in the image conversion process, it is checked whether one or more pages of the unprocessed image data which have not been converted are left. In case that one or more pages of the unprocessed image data are left, the image conversion is executed for each page. The data obtained by the image conversion are immediately stored in the temporary area. As described above, in parallel with the reading of the original, the image conversion and the process for storing the data in the temporary area are executed.
When the reading of the whole original is finished (Step S204; Yes), it is checked whether the image conversion and the process for storing the data in the temporary area, which are executed for the image data of the read whole original (all pages) are finished (Step S205). In case that the image conversion and the process for storing the data in the temporary area are not finished (Step S205; No), the image conversion and the process for storing the data in the temporary area are continued, and the image reading apparatus 10 awaits the finish of the image conversion and the like.
When the image conversion and the process for storing the data in the temporary area are finished (Step S205; Yes), the CPU 11 calculates the charge fee (Step S206). The charge fee is calculated in accordance with the number of the sheets of the read original, the size of the read original, the color/monochrome of each original, and the like. Then, it is checked whether the money which is not less than the charge fee is inserted in the charging vender device 5 (Step S207).
In case that the money which is not less than the charge fee is not inserted (Step S207; No), the CPU 11 (the judgment unit) judges that the data for all pages of the original cannot be transferred to the USB memory, and awaits the insertion of the money. However, in case that the cancel operation is received before the money which is not less than the charge fee is inserted (Step S208; Yes), the inserted money is returned and the job is stopped. Then, the process is ended.
When the money which is not less than the charge fee is inserted (Step S207; Yes), the CPU 11 (the judgment unit) judges that the data for all pages of the original can be transferred to the USB memory. Then, the CPU 11 (the executing unit) instructs each unit of the image reading apparatus 10 to transfer the data stored in the temporary area to the USB memory connected with the connecting unit 23 (Step S209). When the transfer of the data is finished, the charge fee is collected (Step S210). Then, the process is ended. Alternatively, in the process, the sequence of the steps can be changed as follows. In case that the reading of all pages of the original is finished (Step S204; Yes), the process proceeds to Steps S206 and S207. In case that the money which is not less than the charge fee is inserted (Step S207; Yes), in Step S205, it may be checked whether the image conversion and the process for storing the data in the temporary area are finished.
FIG. 5 shows the process for executing the Scan To USB job in accordance with the second mode of the process method C. The process from Step S301 to Step S304 is the same as the process from Step S201 to Step S204 in FIG. 4. Therefore, the explanation thereof is omitted.
When the reading of the whole original is finished (Step S304; Yes), the charge fee is calculated (Step S305). Then, it is checked whether the money which is not less than the charge fee is inserted in the charging vender device 5 (Step S306).
In case that the money which is not less than the charge fee is not inserted (Step S306; No), the CPU 11 (the judgment unit) judges that the data for all pages of the original cannot be transferred to the USB memory, and awaits the insertion of the money. However, in case that the cancel operation is received while the CPU 11 awaits the insertion of the charge fee (Step S307; Yes), the inserted money is returned and the job is stopped. Then, the process is ended.
When the money which is not less than the charge fee is inserted (Step S306; Yes), the CPU 11 (the judgment unit) judges that the data for all pages of the original can be transferred to the USB memory. Then, the CPU 11 (the executing unit) instructs each unit of the image reading apparatus 10 to temporarily stop the image conversion and to transfer the data which have been stored in the temporary area before now to the USB memory (Step S308). Further, it is checked whether the image conversion and the process for storing the data in the temporary area, which are executed for the image data of the read whole original are unfinished (Step S309). When the image conversion and the process for storing the data in the temporary area are finished (Step S309; No), the charge fee is collected (Step S311). Then, the process is ended.
In case that the image conversion and the process for storing the data in the temporary area are unfinished (Step S309; Yes), the CPU 11 (the executing unit) changes the transfer route and instructs each unit of the image reading apparatus 10 to restart the image conversion. That is, the data obtained by the restarted image conversion are directly transferred to the USB memory without using the temporary area (Step S310). When the image conversion and the process for transferring the data to the USB memory, which are executed for the image data of the read whole original, are finished, the charge fee is collected (Step S311). Then, the process is ended.
In the process shown in FIG. 5, in case that the image data to be converted are left after it is confirmed that the amount of the inserted money is not less than the charge fee, the data obtained by the image conversion are directly transferred to the USB memory without using the temporary area. Therefore, as compared with the case in which the data are transferred to the USB memory via the temporary area, the load caused by transferring the data is reduced. As a result, it is possible to shorten the whole process time for executing the job.
In case that the data are stored in the USB memory as a file, in the process shown in FIG. 4, because the data are transferred to the USB memory after the image data corresponding to the whole original are converted and the data obtained by the image conversion are stored in the temporary area, it is possible to transfer the data as one file to the USB memory. In the process shown in FIG. 5, the data to be transferred to the USB memory in Step S308 and the data to be transferred to the USB memory in Step S310 are formed as separate files. However, in case of the job in which the data for each page is stored as a separate file, the above problem is not caused.
As described above, the embodiment is explained by using the drawings. However, in the present invention, the concrete configuration is not limited to the above embodiment. In the present invention, various modifications of the above embodiment or the addition of various functions or the like to the embodiment can be carried out without departing from the gist of the invention.
For example, in the embodiment, the Scan To USB job for designating the USB memory connected with the connecting unit 23 as the transfer destination is explained as an example. The transfer destination (the destination) is not limited to this. For example, the transfer destination (the destination) may be an external terminal which is connected via a network, or the like. In case that an external terminal is the transfer destination, the data transfer may be executed by the network transmission using the protocol, such as SMB, FTP or the like, or by transmitting the data as a file attached to an e-mail. Further, a tablet terminal connected by using the Wi-Fi, or the like may be set to the transfer destination. In this case, the network communication unit 17 has the function as the transfer unit for transferring the data to the designated destination.
Further, in the embodiment, in accordance with the charge check, it is judged whether the data can be transferred. However, the judgment process for judging whether the data can be transferred may be executed in accordance with another standard. For example, in case that the upper limit of the number of the available sheets is managed for each user or each group, the CPU 11 (the judgment unit) compares the number of the remaining sheets which can be used by the user or in the group with the number of the sheets of the read original. In case that the number of the remaining sheets is not less than the number of the sheets of the read original, the CPU 11 judges that the data can be transferred. In case that the number of the remaining sheets is less than the number of the sheets of the read original, the CPU 11 judges that the data cannot be transferred.
Further, the judgment process for judging whether the data can be transferred may be executed in accordance with the free space of the USB memory or the like. That is, in case that the data size of the data obtained by the image conversion executed for the whole original is not less than the free space of the USB memory, the CPU 11 judges that the data can be transferred. In case that the above data size is less than the free space of the USB memory, the CPU 11 judges that the data cannot be transferred.
Further, in the embodiment, after the reading of the whole original is finished, the charge check (the judgment process for judging whether the data can be transferred) is executed. However, for example, the amount of the inserted money is repeatedly checked, and the data which can be processed in proportion to the amount of the inserted money may be transferred. On the other hand, with respect to the data which cannot be processed in proportion to the amount of the inserted money, the image conversion and the process for storing the data in the temporary area are executed, and the data transfer is stopped. Then, in case that the money is inserted more, the data transfer may be executed in proportion to the amount of the inserted money.
In the embodiment, before it is judged that the data can be transferred, the image conversion is executed for the image data of the read original and the data obtained by the image conversion is stored in the temporary area. However, it is not necessary to store the data in the temporary area after all of the processes to be executed before the data transfer are executed. For example, in the temporary area, the data for each page is stored as a separate file. After it is judged that the data can be transferred, the separate files may be incorporated into one or some files and one or some files may be transferred. Before it is judged that the data can be transferred, all of the processes to be executed before the data transfer may be executed and the data may be stored in the temporary area. In this case, because only the data transfer is executed when it is judged that the data can be transferred, it is possible to shorten the process time.
In the embodiment, it is disclosed that the image data is converted into a file having the PDF format or the like and the file is transferred to the transfer destination. However, it is not necessarily required to form a file. The data format may be optionally selected. Further, another file format can be used.
One of the objects of the above embodiment is to provide an image reading apparatus and a non-transitory computer-readable recording medium which prevents the processed data from being transferred to an external device without paying the charge fee in case that a user is charged for the job for converting the image data obtained by reading an original and for transmitting the data to the external device, and which can shorten the whole process time.
In this embodiment, regardless of whether the judgment unit judges that the data can be transferred, the original is read by the reading unit, the image conversion is executed by the image conversion unit and the data obtained by the image conversion is stored in the storing unit. The data obtained by the image conversion is transferred after the judgment unit judges that the data can be transferred. Because the image conversion is executed before the judgment unit judges that the data can be transferred, it is possible to shorten the whole process time to finish the job as compared with the case in which the image conversion is executed after the judgment unit judges that the data can be transferred.
In this embodiment, in case that the usage fee is charged, the judgment unit judges whether the data can be transferred according to whether the amount of inserted money is not less than the charge fee. In case that the upper limit of the number of sheets which can be used by each user or in each group is set, the judgment unit judges whether the data can be transferred, by comparing the number of the remaining sheets to the upper limit with the number of the sheets of the original.
In this embodiment, for example, the recording medium is a USB memory. The recording medium may be an SD card or the like.
In this embodiment, because the charge fee or the number of the sheets of the original is determined after the reading of the all pages of the original is finished, the judgment unit judges whether the data can be transferred after the charge fee or the like is determined.
This embodiment is preferable in case that all data obtained by the image conversion are transferred to the destination as one file.
In this embodiment, in case that the image data which has not been converted is left after the judgment unit judges that the data can be transferred, the data obtained by converting the left image data is directly transferred to the destination without using the storing unit. Therefore, the load caused by transferring the data is reduced. As a result, it is possible to shorten the process time.
In this embodiment, in case that the judgment unit does not judge whether the data can be transferred, the data obtained by the image conversion is directly transferred to the destination without using the storing unit. Therefore, the data transfer can be early started and it is possible to shorten the whole process time.
According to the image reading apparatus and the non-transitory computer-readable recording medium, it is possible to prevent the processed data from being transferred to an external device without paying the charge fee in case that a user is charged for the job for converting the image data obtained by reading an original and for transmitting the data to the external device, and to shorten the whole process time.
The present U.S. patent application claims the priority of Japanese Patent Application No. 2014-085016, filed on Apr. 16, 2014, according to the Paris Convention, and the entirety of which is incorporated herein by reference for correction of incorrect translation.
