Media ejecting device

Abstract

A media ejecting apparatus includes an ejection roller to eject a medium, a first ejection tray located below the ejection roller, a second ejection tray located above the ejection roller, a guide located in a vicinity of the ejection roller and rotatable around a rotation shaft of the ejection roller between a first position to guide the medium ejected by the ejection roller toward the first ejection tray and a second position to guide the medium ejected by the ejection roller toward the second ejection tray, a driving mechanism including a motor to move the guide between the first position and the second position, and control circuitry configured to control the driving mechanism. The guide located at the second position guides the medium between the ejection roller and the guide to the second ejection tray.

1 . A media ejecting apparatus comprising:
 an ejection roller to eject a medium;   a first ejection tray located below the ejection roller;   a second ejection tray located above the ejection roller;   a guide located in a vicinity of the ejection roller and rotatable around a rotation shaft of the ejection roller between a first position to guide the medium ejected by the ejection roller toward the first ejection tray and a second position to guide the medium ejected by the ejection roller toward the second ejection tray;   a driving mechanism including a motor to move the guide between the first position and the second position; and   control circuitry configured to control the driving mechanism,   wherein the guide located at the second position guides the medium between the ejection roller and the guide to the second ejection tray.   
     
     
         2 . The media ejecting apparatus according to  claim 1 , further comprising another motor to drive the ejection roller. 
     
     
         3 . The media ejecting apparatus according to  claim 1 ,
 wherein the guide includes a rotation shaft,   wherein the media ejecting apparatus further comprises an interrupter located between the guide and the rotation shaft of the guide,   wherein the driving mechanism further drives the ejection roller, and   the interrupter interrupts a driving force generated from the motor and transmitted to the rotation shaft of the guide for a predetermined period of time.   
     
     
         4 . The media ejecting apparatus according to  claim 3 , wherein,
 the rotation shaft of the guide includes a protrusion,   the interrupter includes a cam fixed to the guide,   the cam includes a space for the protrusion to rotate and a contact portion located in the space, and   the interrupter further interrupts the driving force generated from the motor and transmitted to the rotation shaft of the ejection roller until the protrusion rotates to contact the contact portion in the space.   
     
     
         5 . The media ejecting apparatus according to  claim 1 , further comprising an assist roller located above the ejection roller and facing the ejection roller,
 wherein the assist roller assists the ejection roller in ejecting the medium to the second ejection tray.   
     
     
         6 . The media ejecting apparatus according to  claim 1 , further comprising:
 an imaging device; and   a sensor located upstream from the imaging device in a media conveyance direction,   wherein the control circuitry is further configured to:
 determine whether the medium conveyed is a separator medium based on an output signal from the sensor; and 
 control the driving mechanism to change a position of the guide based on a determination indicating whether the medium conveyed is the separator medium.
