Paper holder device

Abstract

A paper holder device to simplify the structure and reduce the cost and size of a paper holder device in which paper is fed from a paper roll and cut automatically by electrically-driven means. The paper holder device includes a paper supporting mechanism, a paper feeding mechanism, a paper receiving part, and a paper cutting mechanism for cutting paper, and the paper feeding mechanism and the paper cutting mechanism are configured to be alternatively driven by a single driving gear mechanism.

1 . A paper holder device, comprising
 a paper supporting mechanism for unrollably supporting a paper roll,   a paper feeding mechanism for unrolling paper from the paper roll and feeding the paper,   a paper receiving part for folding the paper fed out of the paper feeding mechanism in a zigzag fashion sequentially and holding the paper, and   a paper cutting mechanism for cutting the paper between the paper feeding mechanism and the paper receiving part,   wherein the paper feeding mechanism and the paper cutting mechanism are configured to be alternatively driven by a single driving gear mechanism.   
     
     
         2 . A paper holder device according to  claim 1 ,
 wherein the driving gear mechanism comprises a reversibly rotatable motor, and a driving gear which receives a driving force from the motor and is driven to rotate selectively in a forward direction or a reverse direction and which is swung between a first position and a second position by the driving force,   and the driving gear is in mesh with a feeding gear unit of the paper feeding mechanism and drives the paper feeding mechanism to rotate when set in the first position, and is in mesh with a cutting drive gear of the paper cutting mechanism and drives the paper cutting mechanism to rotate when set in the second position.   
     
     
         3 . A paper holder device according to  claim 1 ,
 further comprising a first sensor for detecting the presence or absence of the approach of a human hand, and a second sensor for detecting whether or not a paper is present in the paper receiving part,   wherein the driving gear mechanism is configured to be activated when the first sensor detects the approach of a human hand and the second sensor detects the absence of the paper.   
     
     
         4 . A paper holder device, comprising
 a holder main body having a generally rectangular box-like appearance and attached to a vertical wall,   a paper supporting mechanism for unrollably supporting a paper roll, a paper feeding mechanism for unrolling paper from the paper roll and feeding the paper, a paper receiving part for folding the paper fed out of the paper feeding mechanism in a zigzag fashion sequentially and holding the paper in such a manner that the paper can be taken out of an outlet port thereof, and a paper cutting mechanism for cutting the paper between the paper feeding mechanism and the paper receiving part which are housed in the holder main body, and   an access cover provided as one side wall of four side walls of the holder main body and configured to open vertically,   wherein the three side walls of the four side walls of the holder main body except the side wall as the access cover can be selectively used as a mating surface to the vertical wall.   
     
     
         5 . A paper holder device according to  claim 4 ,
 wherein the outlet port is provided in a part corresponding to any one side wall, each of any two side walls, each of any three side walls or each of all the side walls of the four side walls of the holder main body.
