[Configuration of main unit cover and document reading unit]
Next, FIG. 4 is a schematic cross-sectional view showing the configuration of the main body cover 12 and the document reading unit 40. As shown in FIG. 4, the main body cover 12 includes a placement unit 21 for placing the document 19 before being read by the document reading unit 40, and a stacking unit for collecting the document 19 after being read by the document reading unit 40. 31 and the document 19 from the placement unit 21 via the reading surface 11A (that is, after the document 19 is read by the document reading unit 40 held at the document automatic conveyance reading position 3) to the stacking unit 31 And a transport unit 25. Hereinafter, the placement unit 21, the stacking unit 31, and the conveyance unit 25 are collectively referred to as the automatic document conveyance device 5.

  As shown in FIG. 4, the document reading unit 40 includes a light source 43 that irradiates light to the document 19, and an optical element group 42 such as a mirror and a lens that collects reflected light reflected by the document 19. And an image sensor 41 for reading an image from the document 19. That is, the document reading unit 40 irradiates light from the light source 43, collects the reflected light reflected by the document 19 by the optical element group 42, and recognizes the collected reflected light by the image sensor 41. 19 is configured to be read.

  Further, the document reading unit 40 can read the document 19 at a position facing the automatic document conveyance reading position 3, and the document reading unit driving mechanism (not shown) of the main body case 11 along the reading surface 11 </ b> A. It is configured to be movable in the longitudinal direction (left-right direction in FIG. 4).

  That is, when reading the document 19 using the automatic document feeder 5, the document reading unit 40 is held at a position facing the automatic document conveyance reading position 3, and the document conveyed by the automatic document feeder 5. From 19, the entire image of the original 19 is read. Further, when reading the document 19 arranged so as to cover the reading surface 11A (used as a so-called flat bed type), the document reading unit 40 is read while being moved by the document reading unit driving mechanism. All images of the document 19 arranged on the surface 11A are read.

  Next, the placement portion 21 is provided with a placement portion detection sensor 24 that detects that the document 19 is placed on the placement portion 21, and the body case 11 has the reading surface 11 </ b> A on the reading surface 11 </ b> A. A reading surface detection sensor 35 (see FIG. 5) for detecting that is disposed. Hereinafter, the placement portion detection sensor 24 and the reading surface detection sensor 35 are collectively referred to as a document detection sensor (see FIG. 5) 92.

  The placement unit detection sensor 24 and the reading surface detection sensor 35 are optical sensors each including a light emitting unit 24A and a light receiving unit 24B, and a light emitting unit 35A and a light receiving unit 35B.

Oppositely arranged so as to block light.

  However, in the reading surface detection sensor 35, the light receiving unit 35 </ b> B is arranged at a position outside the moving path in which the document reading unit 40 moves in the main body case 11, and the light emitting unit 35 </ b> A is arranged in the main body cover 12. That is, the reading surface detection sensor 35 is configured such that the light receiving unit 35B receives the light emitted from the light emitting unit 35A when the main body cover 12 is closed.

  Therefore, in the document detection sensor 92, when the document 19 is not present at the installation position, the light emitted from the light emitting units 24A and 35A is detected by the light receiving units 24B and 35B. The light reception signal having a large signal level is obtained. When the document 19 is present at the position where the document detection sensor 92 is installed, the light received by the light emitting units 24B and 35B is blocked by the document 19 and is not detected by the light receiving units 24B and 35B. From 35B, a light reception signal having a small signal level is obtained.

[Explanation about control system]
Next, FIG. 5 is a block diagram illustrating a configuration of a control system of the multifunction machine 1. The MFP 1 includes a network interface (network I / F) 108 for connecting to an external device such as a personal computer and a network (not shown) such as the Internet, and a facsimile interface (facsimile I) for connecting to a telephone line. / F) 104, a connection unit 106 as an example of a reading unit to which a USB memory 105 as an example of a portable storage medium capable of reading and writing data is attached and detached, and a process for controlling various driving of the multifunction device 1 ROM 101 for storing a program, RAM 102 for temporarily storing processing results , and NVRAM (nonvolatile memory) as an example of character string storage means for storing data that needs to be stored even when the power is turned off 107 and C for executing the processing program stored in the ROM 101 And U103, are provided.

  Further, the CPU 103 includes the document reading unit 40, the image forming unit 2, the display driving unit 91 that displays an image on the display unit 15, the operation detection unit 90 that detects that the operation unit 14 is operated, and the above-described operation. The document detection sensor 92 is connected.

  The connection unit 106 is configured to energize the USB memory 105 when the USB memory 105 is attached, and includes a connection detection unit 93 that detects that the USB memory 105 is attached. The data stored in the USB memory 105 is a file having a general-purpose image format such as JPEG or TIFF, a file created by general word processing software, a document file such as a PDF format, or a printer driver. There are various forms such as a file of the print data.

[Processing in the above control system (file display list update processing)]
Next, in the multi function device 1, when the USB memory 105 is attached to the connection unit 106, data is read from the USB memory 105, and an image is directly formed on the paper 18 via the image forming unit 2 based on the data. Print processing is executed. Hereinafter, the direct printing process will be described.

  FIG. 6 is a flowchart showing a file display list update process executed by the CPU 103 based on a program stored in the ROM 101, triggered by the USB memory 105 being attached to the connection unit 106, in the direct print process. is there.

  As shown in FIG. 6, in this process, first, in S1 (S represents a step: the same applies hereinafter), it is determined whether or not a USB file display request has been made after insertion of the USB memory 105. The USB file display request is a request for displaying a file input via the cross key 14D or the like and stored in the USB memory 105.

  If no USB file display request has been made (S1: N), the process is temporarily terminated. If a USB file display request has been made (S1: Y), user registration is performed in the USB memory 105 and the NVRAM 107 in S2. It is determined whether information is stored. Note that the user registration information is information in which authorized users of the USB memory 105 and the multifunction device 1 are registered with a character string (hereinafter referred to as a user character string) such as a user name (which may be an ID or the like). It is.

  The user registration work for storing the user registration information can be performed only by, for example, an administrator who has authority to manage the multifunction device 1. For example, the USB memory 105 is attached to the connection unit 106 of the multifunction device 1. In this state, the user enters a “user registration mode” by a predetermined key operation, and a character string (user character string) such as a user name permitted to use the multifunction device 1 is stored in a specific storage area of the NVRAM 107 and the USB memory 105. User registration is performed by storing. Such user registration may be performed only by storing the user registration information in the NVRAM 107 of the multifunction machine 1, but by storing the same user registration information in the USB memory 105, the registered USB memory It is possible to further improve security by permitting use of only 105.

  If the user registration information is not stored in the USB memory 105 and the NVRAM 107 (S2: N), the process is temporarily terminated as it is. If the user registration information is stored (S2: Y), the process continues to S3. Transition.

  In S3, one of the files stored in the USB memory 105 is set as a comparison file. In the subsequent S4, the user character string (if a plurality of user character strings are registered, one of the user character strings) is added to the character string (excluding the extension) of the file name set as the comparison target in S3. It is determined whether or not one is included. If the user name string is included in the file name (S4: Y), whether or not all the files in the USB memory 105 have been checked in S6 after the file name is put in the display list in S5. To be judged. If all the files in the USB memory 105 have not been examined (S6: N), the process proceeds to the above-described S3, and one of the other files stored in the USB memory 105 is set as a comparison file. The above processing is executed.

  If no user character string is included in the file name of the file set as the comparison reference in S3 (S4: N), the process proceeds to S7. In S7, the file name of the file is replaced with the character string xxxx, and is put in the display list, and the process proceeds to S6 described above. In this way, when all the files in the USB memory 105 are checked by repeatedly executing the processes of S3 to S7 (S6: Y), the process is temporarily ended.

  With the above processing, for example, when “Yamada” and “suzuki” are registered as user character strings, when the USB memory 105 storing the file illustrated in FIG. 7A is attached. A display list as illustrated in FIG. 7B is created. That is, for a file that does not include the character string “Yamada” or “suzuki” in the file name, the file name is replaced with the character string xxxx. In addition, the * mark shown in FIG. 7B is a flag representing a file name to be displayed on the display unit 15 as described below.

[Processing in the above control system (print / delete processing of selected file)]
Next, FIG. 8 is a flowchart showing print / deletion processing of the selected file executed by the CPU 103 based on the program stored in the ROM 101 following the file display list update processing. As shown in FIG. 8, in this process, first, in S 21, the file name of the file with the * mark among the files in the display list is displayed on the display unit 15. In subsequent S22, it is determined whether or not the up / down key of the cross key 14D has been pressed. If not (S22: N), it is determined in S23 whether or not the SET key of the cross key 14D has been pressed. Is done. If the SET key is not pressed (S23: N), it is determined whether or not the cancel key 14E is pressed in S24. If the cancel key 14E is not pressed (S24: N), the process is performed. The process proceeds to S22 described above. That is, until the up / down key of the cross key 14D, the SET key, or the cancel key 14E is pressed, the process waits by the loop processing of S22 to S24.

  If the cancel key 14E is pressed during the loop process of S22 to S24 (S24: Y), the process ends as it is, and if the up / down key is pressed during the loop process of S22 to S24 (S22: Y), the process is completed. Shifts to S25. In S25, the above-mentioned * mark is moved up or down by one. In the subsequent S26, the file name of the file to which the * mark is given is displayed on the display unit 15, and then the process proceeds to the above-described S22. For this reason, the user can display a file to be printed or deleted on the display unit 15 by operating the up and down keys by the processing of S22 to S26.

  On the other hand, when the SET key is pressed during the loop processing of S22 to S24 (S23: Y), “Print?” Is displayed on the display unit 15 in S31. In subsequent S32, it is determined whether or not the up / down key has been pressed. If not (S32: N), it is determined in S33 whether or not the SET key has been pressed. If the SET key has not been pressed (S33: N), the process proceeds to S32 described above, and the display unit 15 is displayed as “Print?”, And a standby is performed by the loop process of S32 and S33.

  If the up / down key is pressed during the loop process of S32 and S33 (S32: Y), the process proceeds to S34, and the display of “Print?” Is switched to the display of “Delete?”. Then, while displaying “Delete?” On the display unit 15, standby is performed by the loop processing of S 32 and S 33. If the up / down key is pressed again in this state (S32: Y), the display of “Delete?” Is switched to the display of “Print?” In S34, and the loop processing of S32 and S33 is executed again. .

  If the SET key is pressed during the loop process of S32 and S33 (S33: Y), the process proceeds to S37, and it is determined whether or not the file name displayed last by the process of S26 is xxxx. Is done. If the file name is xxxxxxx (S35: Y), a rejection sound is heard in S36 and the process is terminated. If the file name is not xxxx (S35: N), the file is not updated in S37. Printing or deletion is executed, and the process ends. That is, in S37, when “SET?” Is displayed on the display unit 15 when the SET key is pressed (S33: Y), the process of printing the file is displayed on the display unit 15 as “Delete?”. If so, the process of deleting the file is executed.

[Effects of the present embodiment]
As described above, in the present embodiment, only when a user character string registered as user registration information is included in the file name (S4: Y), the file can be selected and printed or deleted (S37). ). For this reason, even when the USB memory 105 is shared by a plurality of people, only the data of the file corresponding to the authorized user can be printed, and the use of the device by a person other than the authorized user is suppressed. Can do.

Furthermore, in this embodiment, since it is determined whether or not the file is a legitimate user based on the file name (S4), the legitimate user stores data in the USB memory 105 using a personal computer or the like. Can be printed or deleted as described above simply by assigning a file name including a character string registered in advance according to itself. In the above embodiment, files that cannot be printed are also displayed with the file name replaced with xxxx (S7), so it is possible to know what data is stored in the USB memory 105, including files that cannot be printed. be able to. In the above processing, the processing of S4 is determination means, the processing of S21, S26 are in Viewing means, the processing of S25 is to select means, corresponding respectively.

[Modification of the above embodiment]
The present invention is not limited to the above-described embodiment, and can be implemented in various forms without departing from the gist of the present invention. For example, in the above embodiment, when the file name is xxxx (S35: Y), it is assumed that neither printing nor deletion can be performed, but an administrator password or the like is input when a rejection sound is generated (S36). In addition, a file displayed as “xxxx” may be printed or deleted.

  In addition, files that cannot be printed may not be displayed. FIG. 9 is a flowchart showing a file display list update process corresponding to such a form. This process is different from the process of FIG. 6 in that S7 is omitted, and is otherwise the same as the process of FIG. That is, in this process, when the user character string is not included in the file name (S4: N), the file is not put in the display list and the process proceeds to the process for the next file as it is (S6: Y), Alternatively, the process ends (S6: Y).

In this case, when “Yamada” and “suzuki” are registered as user character strings, when the USB memory 105 storing a file as illustrated in FIG. A display list as illustrated in B) is created. In other words, a file in which the character string “Yamada” or “suzuki” is not included in the file name is excluded from the display list. In this case, since only the files that can be printed or deleted are displayed on the display unit 15 in the processing of S22 to S26 in FIG. 8, selection of the file to be printed or deleted becomes easier. In the process of FIG. 8 to be executed in this case, the processing of S21, S26 are in Viewing means, the processing of S25 is to select means, corresponding respectively.

  Further, in each of the above embodiments, the user registration information registered in the USB memory 105 and the NVRAM 107 in advance and the file name are collated, but the user character string as the user registration information is displayed on the operation unit 14 by the user when printing. You may make it input via. FIG. 11 is a flowchart showing a file display list update process corresponding to such a form. This process is different from the process of FIG. 9 in that the process of S2 is changed to S2a and S2b, and the other processes are the same as the process of FIG.

  That is, in this process, when a USB file display request is made (S1: Y), it is determined in S2a whether or not a user character string has been input via the operation unit 14. If no user character string has been input (S2a: N), it is determined in S2b whether or not a predetermined time has elapsed since the start of processing. If the predetermined time has not elapsed (S2b: N), the process proceeds to S2a. In S2a, if the user character string is input but does not match the user registration information registered in the USB memory 105 and the NVRAM 107, it is determined that the input is invalid, and the authorized user input is recognized. No (S2a: N).

  Thus, if the user character string is input (S2a: Y) before the predetermined time has elapsed while the processes of S2a and S2b are repeated (S2b: N), the process proceeds to S3 described above for comparison. A control file is set. Then, in the subsequent S4, the input user character string and the file name are compared. On the other hand, if the user character string is not input (S2a: N) and the predetermined time has passed (S2b: Y) while the processes of S2a and S2b are repeated, the processes in FIGS. As in the case where there is no user registration information, the processing is temporarily terminated as it is.

  As described above, when an appropriate user character string is not input from the operation unit 14 when the user performs printing, the file name of the data stored in the USB memory 105 is not displayed at all. Cannot delete. For this reason, even if the USB memory 105 is transferred to a third party and happens to be attached to the multifunction device 1 to which use permission is granted, the data stored in the USB memory 105 is stored in the third party. Can prevent unauthorized printing.

  In each of the above embodiments, the case where data is stored in units of files in the USB memory 105 has been described as an example. However, when a folder storing a plurality of files is stored in the USB memory 105, the folder is stored. The same processing may be performed for the above. In this case, when a folder including the user character string is selected and the SET key is pressed (S23: Y), a desired file may be selected from the folder by the same processing as S22 to S26. In this case, even if the file name of each file is an arbitrary file name, the file can be printed or deleted if it is stored in the folder containing the user character string. Furthermore, the portable storage medium is not limited to a USB memory, and various media such as a memory card can be applied.
