Feeding device and recording device

Abstract

A feeding device includes a mounting portion capable of mounting a plurality of recording media thereon in a stacked state, a delivering member for performing delivery of the top recording medium by performing a feeding motion in a state in which an contact surface thereof is in contact with the top recording medium of the recording media mounted on the mounting portion so that the top recording medium is delivered in a feeding direction of the recording media due to the frictional force generated between the top recording medium and the contact surface of the delivering member, the frictional force being used as transporting force, and a separating member.

1 . A feeding device comprising:
 a mounting portion capable of allowing a plurality of recording media to be mounted thereon in a stacked state;   a delivering member which performs delivery of the top recording medium by performing a feeding motion in a state in which a contact surface thereof is in contact with the top recording medium of the recording media mounted on the mounting portion so that the top recording medium is delivered in a feeding direction of the recording media due to the frictional force generated between the top recording medium and the contact surface of the delivering member, the frictional force being used as transporting force; and   a separating member having an inclined surface, against which a leading end of the recording medium delivered by the delivering member hits up against, and fixed in place at a downstream side of the mounting portion in the feeding direction of the recording media and at a portion at which the separating member can be in contact with the contact surface of the delivering member,   wherein the delivering member is structured such that the contact surface of the delivering member is formed by a contact surface forming member which elastically deforms when it is pressed, and the top recording medium, which is delivered by the delivering member and of which the leading end hits up against the inclined surface of the separating member, is fed, resisting against elastic recovery force of the contact surface forming member by pressing the contact surface of the delivering member so as to elastically deform the contact surface forming member so that a gap is formed between the contact surface and the separating member through which only the top recording medium can pass.   
     
     
         2 . The feeding device according to  claim 1 , further comprising:
 an urging member capable of urging the contact surface forming member in a direction in which the contact surface gets close to and away from the separating member.   
     
     
         3 . The feeding device according to  claim 2 , wherein the urging member is a spring member which urges the contact surface forming member via a slider. 
     
     
         4 . The feeding device according to  claim 1 , wherein the delivering member is a feeding roller having a rigid base portion supported so as to be able to rotate around a rotary shaft, an outer side of the rigid base portion covered with the contact surface forming member. 
     
     
         5 . The feeding device according to  claim 4 , wherein the feeding roller has an outer surface formed by the contact surface forming member, the outer surface being composed of a circumferential surface having a radius equal to the distance from the rotary shaft and a non-circumferential surface which is distanced shorter than the distance between the rotary shaft than the circumferential surface, in which the circumferential surface forms the contact surface. 
     
     
         6 . A recording device comprising:
 a recording portion performing recording on a recording medium; and   the feeding device according to  claim 1  for feeding the recording medium to the recording portion.
