Roll Paper Holder

Abstract

Disclosed is a roll paper holder in which a leading end of roll paper extends outwardly from the roll paper holder by a certain length after cutting of the roll paper, to allow the user to easily grasp the leading end of the roll paper.

1 . A roll paper holder comprising a pair of side members, a support shaft for supporting roll paper between the side members, a backing member mounted to front sides of the side members, and a cover member rotatably mounted to the side members while facing the backing member, further comprising:
 a concave portion formed at the backing member;   a convex portion formed at the cover member to correspond to the concave portion;   a cutter formed at a lower end of the cover member; and   an elastic member mounted to the backing member, to be arranged over the concave portion.   
     
     
         2 . The roll paper holder according to  claim 1 , wherein the cover member comprises a pair of legs formed at one side of the cover member, second fixed pins respectively protruded from outer ends of the legs, and grooves respectively formed at inner ends of the legs,
 wherein each of the side members comprises guide holes to receive the second fixed pins, respectively, fulcrum pins respectively fitted in the grooves, and first fixed pins,   wherein a coil spring is mounted between each of the second fixed pins and a corresponding one of the first fixed pins.   
     
     
         3 . The roll paper holder according to  claim 1 , wherein the cutter comprises:
 a saw-shaped tooth portion formed at a lower end of the cover member;   a spring member formed between the tooth portion and the convex portion of the cover member; and   a spring plate formed at an end of the spring member.   
     
     
         4 . The roll paper holder according to  claim 3 , wherein the spring member comprises:
 a pair of coil springs; and   three coil springs arranged between the pair of coil springs while having a shorter length than the pair of coil springs.   
     
     
         5 . The roll paper holder according to  claim 1 , wherein the cutter comprises:
 a horizontally-elongated tooth portion formed at a lower end of the cover member;   spring members respectively formed at upper and lower sides of the tooth portion; and   spring plates each formed at an end of a corresponding one of the spring members,   wherein the tooth portion is inserted into a concave portion formed on the backing member at a position corresponding to the tooth portion.   
     
     
         6 . The roll paper holder according to  claim 1 , wherein the cutter comprises:
 a horizontally-elongated tooth portion formed at a lower end of a connector to connect the pair of legs;   sponges respectively formed at upper and lower sides of the tooth portion; and   spring plates each formed at an end of a corresponding one of the sponges,   wherein the backing member is formed with a concave portion at a position corresponding to the tooth portion,   wherein sponges are mounted to the backing member at upper and lower sides of the concave portion, and spring plates are attached to free ends of the sponges mounted to the backing member, respectively.   
     
     
         7 . The roll paper holder according to  claim 1 , wherein the cutter comprises:
 a 90°-rotated U-shaped recess formed at the backing member;   two parallel spring members mounted at an upper portion of the recess, to extend toward the cover member, respectively attached with spring plates,   a plate-shaped tooth portion disposed at a lower portion of the recess and supported by two spring members, the plate-shaped tooth portion having an inclined surface;   a spring plate support portion formed at a lower end portion of the cover member; and   a tooth portion formed at the cover member beneath the spring plate support portion, to be integral with the spring plate support portion,   whereby, when the cover member is pressed, the tooth portion of the cover member is moved along the inclined surface of the plate-shaped tooth portion, and then cuts an end of the roll paper while coming into contact with the plate-shaped tooth portion, in a manner similar to scissors.   
     
     
         8 . A roll paper holder comprising a pair of side members, a base plate mounted between the side members, to support roll paper laid on the base plate, a backing member mounted to the side members beneath the base plate, and a cover member mounted to the side members to be horizontally movable with respect to the backing member, further comprising:
 a plurality of concave portions formed at the backing member;   a plurality of convex portions formed at the cover member, to correspond to the concave portions of the backing member;   a roll paper cutter formed at the cover member beneath the convex portions;   a guide receiving member mounted to the backing member between the concave portions;   a guide formed at the cover member between the convex portions, to be inserted into the guide receiving member; and   a spring member mounted to an end of the guide inserted into the guide receiving member.   
     
     
         9 . The roll paper holder according to  claim 8 , wherein the cutter comprises:
 a guide plate and a stopper, which are formed at a lower end of the cover member while being vertically spaced apart from each other;   a tooth portion formed between the guide plate and the stopper;   spring members arranged at upper and lower sides of the tooth portion; and   bases formed at the backing member, to correspond to the spring members, respectively,   whereby, when the cover member is pressed, the spring members are pressed against the bases while coming into contact with the bases, and the tooth portion is inserted into a groove defined between the bases.   
     
     
         10 . The roll paper holder according to  claim 8 , wherein the cutter comprises:
 a slider vertically slidably mounted to a lower end of the cover member, and formed with a horizontal groove;   a tooth portion formed at the cover member beneath the slider;   a spring member mounted to the cover member beneath the slider;   a spring plate mounted to a free end of the spring member;   a pair of bases formed on the backing member at a position corresponding to the spring plate; and   a control rod formed on the backing member at a position corresponding to the slider,   whereby, when the cover member is pressed, the control rod is inserted into the slider, the spring plate is pressed against the bases, and the tooth portion is inserted into a space defined between the bases.   
     
     
         11 . The roll paper holder according to  claim 8 , wherein the tooth portion comprises teeth having mountains and valleys, which are alternately arranged.
