Sheet conveyance apparatus, image reading apparatus, and image forming apparatus

Abstract

A sheet conveyance apparatus includes a stacking tray, a conveyance roller, a first sensor configured to detect the sheet, a second sensor configured to detect the sheet, the second sensor and the first sensor being located side by side in a width direction, a controller configured to execute stopping processing to stop conveyance of the sheet based on the first sensor and the second sensor, and a display portion configured to display a predetermined screen configured to set a different-width mixed stacking mode in a case where the stopping processing is executed based on the first sensor and the second sensor.

What is claimed is: 
     
         1 . A sheet conveyance apparatus comprising:
 a stacking tray on which a sheet is stacked;   a conveyance roller configured to convey the sheet stacked on the stacking tray;   a first sensor configured to detect the sheet conveyed by the conveyance roller;   a second sensor configured to detect the sheet conveyed by the conveyance roller, the second sensor and the first sensor being located side by side in a width direction orthogonal to a conveyance direction of the sheet;   a controller configured to execute stopping processing to stop conveyance of the sheet by the conveyance roller in a case where one of the first sensor and the second sensor does not detect the sheet before a predetermined time period elapses since the sheet is detected by the other of the first sensor and the second sensor; and   a display portion configured to display a predetermined screen configured to set a different-width mixed stacking mode, which is a mode to be used when a plurality of sheets with different widths is stacked on the stacking tray, in a case where the stopping processing is executed based on the first sensor and the second sensor.   
     
     
         2 . The sheet conveyance apparatus according to  claim 1 , wherein the controller does not execute the stopping processing based on the first sensor and the second sensor in the different-width mixed stacking mode. 
     
     
         3 . The sheet conveyance apparatus according to  claim 2 , wherein the predetermined screen includes a first setting button for setting the different-width mixed stacking mode and a second setting button for disabling the stopping processing based on the first sensor and the second sensor without setting the different-width mixed stacking mode. 
     
     
         4 . The sheet conveyance apparatus according to  claim 3 , wherein in a case where the stopping processing is executed based on the first sensor and the second sensor in a state where the different-width mixed stacking mode is set, the display portion does not display the second setting button. 
     
     
         5 . The sheet conveyance apparatus according to  claim 1 , wherein the controller controls the conveyance roller in such a manner that an interval between sheets in the different-width mixed stacking mode is larger than the interval in a case where the different-width mixed stacking mode is not set. 
     
     
         6 . The sheet conveyance apparatus according to  claim 1 , further comprising a pair of regulation members configured to be movable in the width direction on the stacking tray, the pair of regulation members being in contact with both edges in the width direction of the sheet stacked on the stacking tray,
 wherein, in the different-width mixed stacking mode, a sheet with a smaller width in a plurality of sheets with different widths stacked on the stacking tray is stacked on the stacking tray in a state where the sheet contacts one of the pair of regulation members, the one of the pair of regulation members being located on a back side.   
     
     
         7 . A sheet conveyance apparatus comprising:
 a stacking tray on which a sheet is stacked;   a conveyance roller configured to convey the sheet stacked on the stacking tray;   a first sensor configured to detect the sheet conveyed by the conveyance roller;   a second sensor configured to detect the sheet conveyed by the conveyance roller, the second sensor and the first sensor being located side by side in a width direction orthogonal to a conveyance direction of the sheet;   a controller configured to determine whether the sheet conveyed by the conveyance roller is skewed based on the first sensor and the second sensor; and   a display portion configured to display a predetermined screen configured to set a different-width mixed stacking mode, which is a mode to be used when a plurality of sheets with different widths is stacked on the stacking tray, in a case where the controller determines that the sheet conveyed by the conveyance roller is skewed.   
     
     
         8 . A sheet conveyance apparatus comprising:
 a stacking tray on which sheets are stacked;   a conveyance roller configured to convey the sheets stacked on the stacking tray;   a first sensor configured to detect the sheets conveyed by the conveyance roller;   a second sensor configured to detect the sheets conveyed by the conveyance roller, the second sensor and the first sensor being located side by side in a width direction orthogonal to a conveyance direction of the sheets;   a controller configured to determine whether the sheets conveyed by the conveyance roller are bound with a staple based on the first sensor and the second sensor; and   a display portion configured to display a predetermined screen configured to set a different-width mixed stacking mode, which is mode to be used when a plurality of sheets with different widths is stacked on the stacking tray, in a case where the controller determines that the sheets conveyed by the conveyance roller are bound with a staple.   
     
     
         9 . An image reading apparatus comprising:
 a sheet conveyance apparatus according to  claim 1 ; and   a reading sensor configured to read an image on a sheet conveyed by the conveyance roller from the stacking tray.   
     
     
         10 . An image forming apparatus comprising:
 an image reading apparatus according to claim  9 ; and   an image forming unit configured to form an image on a recording medium based on image information of a sheet read by the reading sensor.
