Medium supply system and image forming system

Abstract

A medium supply system includes: a supply unit that supplies air to a plurality of stacked recording media while changing a supply direction from an edge side of the recording media to float and separate the recording media; an imaging unit that captures images of the plurality of recording media to which the air is supplied by the supply unit from the edge side; and at least one processor, wherein the processor determines separation of the recording media using an image suitable for determining the separation of the recording media among the images captured by the imaging unit.

What is claimed is: 
     
         1 . A medium supply system comprising:
 a supply unit that supplies air to a plurality of stacked recording media while changing a supply direction from an edge side of the recording media to float and separate the recording media;   an imaging unit that captures images of the plurality of recording media to which the air is supplied by the supply unit from the edge side; and   at least one processor,   wherein the processor determines separation of the recording media using an image suitable for determining the separation of the recording media among the images captured by the imaging unit.   
     
     
         2 . The medium supply system according to  claim 1 , further comprising:
 an irradiation unit that irradiates the recording media in a portion whose image is to be captured by the imaging unit with light,   wherein the processor causes the irradiation unit to irradiate the recording media with the light in a case where the recording media which are floating are in a state suitable for determining the separation of the recording media.   
     
     
         3 . The medium supply system according to  claim 2 , further comprising:
 a moving member that is provided in the supply unit, is disposed at a supply port through which the air is supplied, and moves in a vertical direction to change the supply direction of the air; and   a detection unit that detects a position of the moving member in the vertical direction,   wherein the processor causes the irradiation unit to irradiate the recording media with the light based on a detection result of the detection unit.   
     
     
         4 . The medium supply system according to  claim 1 , further comprising:
 a shielding member that shields a lens of the imaging unit,   wherein the processor releases the shielding by the shielding member in a case where the recording media which are floating are in a state suitable for determining the separation of the recording media.   
     
     
         5 . The medium supply system according to  claim 4 , further comprising:
 a moving member that is provided in the supply unit, is disposed at a supply port through which the air is supplied, and moves in a vertical direction to change the supply direction of the air; and   a detection unit that detects a position of the moving member in the vertical direction,   wherein the processor releases the shielding by the shielding member based on a detection result of the detection unit.   
     
     
         6 . The medium supply system according to  claim 1 , wherein the processor determines the separation of the recording media after the supply direction of the air is changed a plurality of times. 
     
     
         7 . An image forming system comprising:
 the medium supply system according to  claim 1 ; and   an image forming unit that forms an image on each of the recording media supplied from the medium supply system.   
     
     
         8 . An image forming system comprising:
 the medium supply system according to  claim 2 ; and   an image forming unit that forms an image on each of the recording media supplied from the medium supply system.   
     
     
         9 . An image forming system comprising:
 the medium supply system according to  claim 3 ; and   an image forming unit that forms an image on each of the recording media supplied from the medium supply system.   
     
     
         10 . An image forming system comprising:
 the medium supply system according to  claim 4 ; and   an image forming unit that forms an image on each of the recording media supplied from the medium supply system.   
     
     
         11 . An image forming system comprising:
 the medium supply system according to  claim 5 ; and   an image forming unit that forms an image on each of the recording media supplied from the medium supply system.   
     
     
         12 . An image forming system comprising:
 the medium supply system according to claim  6 ; and   an image forming unit that forms an image on each of the recording media supplied from the medium supply system.
