Next, a document reading process of the document reading apparatus 900 will be described with reference to a flowchart.
As illustrated in
In step S903, in a case where it is determined that the document is placed, it is determined whether or not the user is separated from the document reading apparatus 900 by a prescribed distance or more (step S904).
In step S904, in a case where it is determined that the user is separated from the document reading apparatus 900 by the prescribed distance or more, it is further determined whether or not a prescribed time elapses after the user is separated from the document reading apparatus 900 (step S905).
In step S905, in a case where it is determined that the prescribed time elapses after the user is separated, the document is discharged from the document tray 240 to the paper discharge tray 265 (step S907) and the process is returned to step S901.
On the other hand, in step S904, in a case where it is determined that the user is not separated from the document reading apparatus 900 by the prescribed distance or more, it is determined whether or not the first instruction of shifting the document into the paper feeding available state is performed (step S909).
In addition, in step S905, in a case where it is determined that the prescribed time does not elapse after the user is separated, the process proceeds to step S909.
In step S909, in a case where it is determined that the first instruction is not performed, the process is returned to step S904.
On the other hand, in step S909, in a case where it is determined that the first instruction is performed, for the document feeding available state, the document tray 240 is moved to the position at which the document can be fed (step S911) and the pickup roller 253 is disposed to temporally hold the document and to press the document from above (step S913).
It is determined whether or not the second instruction of executing the document reading process is performed (step S915).
In step S915, in a case where it is determined that the second instruction is performed, the document reading process is executed (step S917).
As described above, the document reading apparatus 900 performs the document reading process.
In this configuration described above, the document reading apparatus 900 according to the ninth embodiment further includes the person detecting sensor 890. In a case where the user who is using the document reading apparatus 900 is separated from the document reading apparatus 900 by the prescribed distance or more and the prescribed time further elapses after the user is separated from the document reading apparatus in the state in which the document is placed on the document tray 240, the document on the document tray 240 is discharged, so that it is possible to set a condition that the document is discharged, and it is further possible to suppress the document, of which a user is absent, being left on the document tray 240 and to suppress a loss of the documents and a leakage of information.
In addition, in the ninth embodiment, the person detecting sensor 890 detects that the user is separated when the document is placed on the document tray 240 and the document is discharged in a case where the prescribed time elapses after the user is separated from the document reading apparatus, but the person detecting sensor 890 may detect that the user is separated when the document is in the document feeding available state and the document may be discharged in a case where the prescribed time elapses after the user is separated from the document reading apparatus, for example. With this configuration, it is possible to suppress the document, of which a user is absent, being left on the document tray 240 even in the document feeding available state and to suppress a loss of the documents and a leakage of information.
