Embodiments described herein generally relate to a technology for processing reading images on double sides of a sheet.
Conventionally, a scanner is generally used to read double sides of a sheet to create image files constituted by images on double sides of the sheet.
A scanner is generally used to read a single side or double sides of a sheet to send image files which are constituted by images on the single side or double sides of the sheet to a preset address.
A scanner is generally used to read a single side of a sheet, carry out an OCR (Optical Character Recognition) for an image on the single side and detect an address. The scanner sends an image file constituted by the image on the single side of the sheet to the address.
A scanner is generally used to read a single side of a sheet and stop a sending processing or a printing processing on an image file constituted by an image on the single side if a ground tint indicating forbiddance of processing on the image is detected.
The requests of a user for a scanner are diverse. In a case of reading double sides of a sheet, more diverse methods for processing a reading image are required.
Generally, a scanner of the present embodiment, which reads a first surface with a first reading section configured to read the first surface of a sheet and a second surface with a second reading section configured to read the second surface opposite to the first surface of the sheet, executes individual processing on a first reading image of the first surface and a second reading image of the second surface.
Hereinafter, the embodiment is described with reference to the accompanying drawings.
The image forming apparatus 1 is an MFP (Multi-Function Peripheral) which has a copy function, a printing function, a scanning function, a FAX function, an Email sending function and the like. The image forming apparatus 1 comprises a first reading section 2, a second reading section 3, an image forming section 4, a communication section 5, a controller 6, a HDD 7 (Hard Disk Drive), a display section 81 and an operation section 82.
The first reading section 2 and the second reading section 3 are arranged inside an ADF 9 (Auto Document Feeder).
The ADF 9 feeds a sheet from a sheet feeding tray 91 to a conveyance path 92 inside the ADF 9. The ADF 9 discharges the sheet to a sheet discharging tray 93 after images on double sides of the sheet are read by the first reading section 2 and the second reading section 3.
A space D between the first reading section 2 and the second reading section 3 in the conveyance direction of the sheet is shorter than a length of the sheet in the conveyance direction. The sheet which specifies a maximum space D is a sheet having the smallest size among the sheets subjected to a reading operation. For example, the maximum space D is 140 mm which is a length in the conveyance direction of a sheet having a size of an STMT (Statement Half Letter).
As the space D between the first reading section 2 and the second reading section 3 in the conveyance direction is shorter than the length of the sheet in the conveyance direction, the first reading section 2 and the second reading section 3 can read double sides of the sheet simultaneously. Hereinafter, in a case of reading double sides of the sheet with the first reading section 2 and the second reading section 3, it is usually described that double sides of the sheet are read by the first reading section 2 and the second reading section 3 simultaneously.
The first reading section 2 reads a front surface (a first surface) of the sheet on the sheet feeding tray 91. The front surface of the sheet refers to the upper surface of the sheet on the sheet feeding tray 91. The rear surface of the sheet refers to the lower surface of the sheet on the sheet feeding tray 91.
The second reading section 3 reads the rear surface (a second surface) of the sheet on the sheet feeding tray 91.
The first reading section 2 and the second reading section 3 may be a CIS (Contact Image Sensor) or a CCD (Charge Coupled Device).
