  As shown in FIG. 6, when there is any operation on the image reading apparatus 10 (YES in step # 1), the USB memory attachment detection unit 201 attaches the USB memory M to the USB attachment unit 23. It is detected whether or not the operation is to be performed (step # 2).

  If the USB memory attachment detection unit 201 detects that the operation performed in step # 1 is not an operation for attaching the USB memory M to the USB attachment unit 23 (NO in step # 2), job execution The instruction unit 204 waits until a job execution instruction is issued (NO in step # 3). When there is a job execution instruction (YES in step # 3), the instruction unit 204 causes each unit in the image reading apparatus 10 to execute the job. (Step # 4).

  On the other hand, the USB memory attachment detection unit 201 indicates that the operation performed in step # 1 is an operation of attaching the USB memory M to the USB attachment unit 23 (the USB memory M is attached to the USB attachment unit 23). Is detected (YES in step # 2), the display control unit 202 displays a registration screen G1 as shown in FIG. 3 on the display unit 172 in response to a request from the authentication processing unit 203 (step 172). # 5).

  The authentication processing unit 203 waits until a user ID is input on the registration screen G1 (NO in step # 6). When the input user ID is accepted (YES in step # 6), the user ID is assigned to the user ID. Store in the ID storage unit 211 (step # 7).

  Next, job execution instructing unit 204 waits until a job execution instruction is received (NO in step # 8). When a job execution instruction is accepted (YES in step # 8), job execution instructing unit 204 It is determined whether or not the job is a scanning (image reading) operation (step # 9).

  If job execution instructing unit 204 determines that the job is a job other than a scan (image reading) operation (NO in step # 9), operation corresponding to the type of job is executed by each unit in image reading apparatus 10. On the other hand (step # 4), if it is determined that the job is a scan (image reading) operation (YES in step # 9), whether or not the USB memory M is designated as the storage destination of the image data read by the scan operation. Is determined (step # 10).

  If the job execution instructing unit 204 determines that a storage destination (internal storage unit 210) other than the USB memory M is designated as the storage destination of the image data read by the scanning operation (NO in step # 10), the scanning operation is performed as the image reading. The image reading unit 16 is caused to perform processing for storing the image data obtained by the reading operation in the storage destination (step # 4).

  On the other hand, when the job execution instructing unit 204 determines that the USB memory M is designated as the storage destination of the image data read by the scan operation (YES in step # 10), the job execution instructing unit 204 causes the image reading unit 16 to perform the scan operation. The image reading unit 16 is made to perform processing for storing the image data obtained by the operation in the USB memory M (step # 11). When the process of storing the image data in the USB memory M is completed, the time measuring unit 205 starts a time measurement operation.

  After the process of step # 11, as shown in FIG. 7, the USB memory attachment detection unit 201 determines whether or not a predetermined time has been measured after the image data is stored in the USB memory M by the time measuring unit 205. (Step # 12) When it is determined that the predetermined time has been counted after the image data is stored in the USB memory M (YES in Step # 12), the time measuring unit 205 stops the time measuring operation, resets the measured value, and the USB memory. The attachment detection unit 201 determines whether or not the USB memory M is removed from the USB attachment unit 23 (step # 13).

  If the USB memory mounting detection unit 201 determines that the USB memory M has been removed from the USB mounting unit 23 (YES in step # 13), the USB memory M terminates the series of processes, while the USB memory M is connected to the USB mounting unit. If it is determined that the USB memory M has not been removed (NO in step # 13), the display control unit 202 displays a guidance screen G2 as shown in FIG. The data processing unit 206 transfers all the data in the USB memory M from the USB memory M to the internal storage unit 210 (step # 14). When the data transfer process is completed, the time measuring unit 205 starts the time measuring operation again.

  Next, the data processing unit 206 detects whether or not the button B4 has been operated on the guide screen G2 (whether or not an instruction to remove the USB memory M from the USB mounting unit 23 has been input) at regular intervals (Step #). 15) If it is determined that the button B4 has not been operated (NO in step # 15), whether or not a predetermined time has been counted after the data is transferred to the internal storage unit 210 by the timer 205. Is determined (step # 16).

  If the data processing unit 206 determines that the predetermined time has not been counted since the data was transferred to the internal storage unit 210 (NO in step # 16), the data processing unit 206 returns to the processing in step # 15 while the data is stored in the internal storage unit 210. If it is determined that the predetermined time has elapsed since the transfer to the storage unit 210, all the data transferred from the USB memory M to the internal storage unit 210 is erased without returning to the USB memory M (step # 17). The display control unit 202 uses the display unit 172 to perform processing for notifying that all data transferred from the USB memory M to the internal storage unit 210 has been erased without returning to the USB memory M ( Step # 27), a series of processing is terminated.

  In step # 15, when it is detected that the button B4 is operated on the guidance screen G2 (input indicating that the USB memory M is removed from the USB mounting unit 23) (YES in step # 15), the display control unit 202 In response to the request from the authentication processing unit 203, a login screen G3 as shown in FIG. 5 is displayed on the display unit 172 (step # 18). The authentication processing unit 203 waits until a user ID is input on the login screen G3 (NO in step # 19). When the user ID is input (YES in step # 19), the user ID is set to step # 19. In step # 20, it is checked whether the user ID is registered in the user ID storage unit 211 (step # 20).

  If the authentication processing unit 203 determines that the user ID is not registered in the user ID storage unit 211 in step # 7 (NO in step # 21), the authentication processing unit 203 and the display control unit 202 Performs a process of informing that using the display unit 172 (step # 22), and returns to the process of step # 18 again to give an opportunity to input an appropriate user ID.

  On the other hand, if the authentication processing unit 203 determines that the user ID matches that registered in the user ID storage unit 211 in step # 7 (YES in step # 21), the data processing unit 206 The data transferred from the USB memory M to the internal storage unit 210 is returned to the USB memory M, and the USB memory M is set in a removable state (step # 23), and the display control unit 202 removes the USB memory M. Is displayed on the display unit 172 (step # 24).

  Then, the USB memory attachment detection unit 201 determines whether or not the USB memory M has been removed from the USB attachment unit 23 (step # 25), and determines that the USB memory M has not been removed from the USB attachment unit 23. (NO in step # 25), the process returns to step # 24. On the other hand, if it is determined that the USB memory M has been removed from the USB mounting unit 23 (YES in step # 25), the display control unit 202 The display of the message indicating that the removal of the USB memory M is permitted is terminated, and the initial screen is displayed (step # 26).

  As described above, when the USB memory M is not removed after the image data generated by the image reading unit 16 is stored in the USB memory M until the predetermined time elapses, the USB memory M is removed. Since the guidance screen G2 that prompts the execution of work is displayed, forgetting to remove the USB memory M can be suppressed.

  If the USB memory M is not removed after the image reading unit 16 stores the image data in the USB memory M until a predetermined time elapses, the image data is stored from the USB memory M to the internal storage. Since the image data is transferred to the unit 210, even if the user forgets to remove the USB memory M, the image data can be prevented from being illegally used by others.

  The image data transferred from the USB memory M to the internal storage unit 210 by the data processing unit 206 is returned to the USB memory M when the authentication processing unit 203 authenticates the user information input by the operation unit 17. As a result, the user can obtain the USB memory M in which the image data of the read original is stored.

  Further, since the image data is returned to the USB memory M by the data processing unit 206, it is conditional on being authenticated by the authentication processing unit 203, the image data is returned to the USB memory M without permission by another person. Can be prevented.

  Further, after the image data is returned to the USB memory M by the data processing unit 206, a message indicating that the removal of the USB memory M is permitted is displayed until the USB memory M is removed from the USB mounting unit 23. Therefore, the occurrence of forgetting to remove the USB mounting portion 23 can be suppressed.

  In addition, when the data processing unit 206 transfers all the data in the USB memory M from the USB memory M to the internal storage unit 210 and the USB memory M is not removed from the USB mounting unit 23 within a predetermined time. Deletes all the data transferred from the USB memory M to the internal storage unit 210 without returning it to the USB memory M, so that the image data remains in the internal storage unit 210 and the image data becomes Unauthorized use in the image reading apparatus 10 or the like can be prevented.

  As described above, even when the image reading apparatus 10 is used in such a form that the image data obtained by the reading operation of the image reading unit 16 is stored in the USB memory M, it is possible to prevent forgetting to remove the USB memory M as much as possible. Even if the user forgets to remove the USB memory M, it is possible to prevent data from being used illegally by others.

  In this case, the following modifications may be employed instead of or in addition to the embodiment.

  (1) Forgetting to remove the USB memory M may be notified by sound together with the display of the guide screen G2.

  (2) The external storage device in this case is not limited to the USB memory M, but also includes a recording medium such as an SD card.
