- 1. Field of the Invention
- The present invention relates to a media dispenser, and more particularly, to a media pick-up device of a media dispenser which can separate media one by one regardless of variations of stiffness of the media.
- 2. Description of the Background Art
-
FIG. 1 is a side diagram illustrating a conventional media pick-up device of a media dispenser, andFIG. 2 is an enlarged diagram illustrating part A ofFIG. 1 . - The conventional media pick-up device includes a pick-up roller (not shown) installed in the rear side of
media 202 discharged from a media cassette (not shown), for discharging the media stored in the media cassette to the lower side direction by friction, and conveyingrollers 204 and separatingrollers 206 installed in the lower side of the pick-up roller, for separating and conveying themedia 202 discharged from the pick-up roller one by one. - The
conveying rollers 204 are fixed to arotation shaft 208 at predetermined intervals, and therotation shaft 208 is rotated by a force of a driving unit. The separatingrollers 206 are at a stationary state or rotated in the opposite direction to theconveying rollers 204, to separate themedia 202 one by one. - The
conveying rollers 204 and the separatingrollers 206 are arranged with predetermined overlaps (P), to generate friction to themedia 202. That is, when themedia 202 are inserted between theconveying rollers 204 and the separatingrollers 206, a normal force is generated due to stiffness of themedia 202, and thus a frictional force is generated between themedia 202 and theseparating rollers 206. Accordingly, themedia 202 are separated and discharged one by one between theconveying rollers 204 and the separatingrollers 206. - In the conventional media pick-up device, stiffness of the
media 202 is reduced due to moisture in a humid area or humid season such as the wet season. Therefore, when themedia 202 pass between theconveying rollers 204 and the separatingrollers 206, the normal force generated on the separatingrollers 206 decreases, and the frictional force generated between theseparating rollers 206 and themedia 202 is reduced. As a result, themedia 202 cannot be separated one by one. - Therefore, an object of the present invention is to provide a media pick-up device of a media dispenser which can accurately separate media one by one by maintaining a frictional force between the media and separating rollers, by changing gaps between conveying rollers and the separating rollers, when the media have low stiffness.
- To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided a media pick-up device of a media dispenser, including: a plurality of conveying rollers rotated by a driving force of a driving means, for conveying media; first separating rollers arranged with predetermined overlaps to the conveying rollers, for separating the media one by one; and second separating rollers arranged to face the conveying rollers with predetermined gaps, for generating a frictional force to the media.
- In order to maintain predetermined intervals between the conveying rollers and the first and second separating rollers, first spacer rollers are mounted on a rotation shaft to which the conveying rollers are fixed, and second spacer rollers corresponding to the first spacer rollers are mounted on a shaft to which the first and second separating rollers are fixed.
- The conveying rollers include first conveying rollers arranged with predetermined overlaps to the first separating rollers, and second conveying rollers arranged to face the second separating rollers with predetermined gaps.
- The second conveying rollers are arranged between the first conveying rollers at predetermined intervals, and the second separating rollers are arranged between the first separating rollers.
- A torsion spring for providing an elastic force to push the first and second separating rollers to the conveying rollers is installed on the shaft to which the first and second separating rollers are fixed.

up roller 42 positioned in the rear side of themedia cassette 2, for dischargingmedia 150 stored in themedia cassette 2 to the lower side direction, aconveying roller unit 44 rotated by the driving force of the driving means, and a separatingroller unit 46 arranged to face theconveying roller unit 44, for separating the media one by one by generating a frictional force to the media. - Here, the conveying
roller unit 44 is comprised of arotation shaft 152 connected to the driving means through the force transmitting means and rotated, firstconveying rollers 154 mounted on therotation shaft 152, and rotated with therotation shaft 152, for conveying themedia 150 when themedia 150 have normal stiffness, andsecond conveying rollers 156 for conveying themedia 150 when themedia 150 have low stiffness. - The separating
roller unit 46 includes ashaft 160 maintaining a stationary state or being rotated in the opposite direction to the conveying rollers, first separatingrollers 162 fixed to theshaft 160 and positioned with predetermined overlaps Q to thefirst conveying rollers 154, for separating themedia 150 one by one by generating the frictional force to themedia 150 when themedia 150 have normal stiffness, and second separatingrollers 164 arranged to face thesecond conveying rollers 156 with predetermined gaps T, for generating the frictional force to themedia 150 when themedia 150 have low stiffness. - Preferably, the second conveying
rollers 156 are arranged between the first conveyingrollers 154 at predetermined intervals, and thesecond separating rollers 164 are arranged between thefirst separating rollers 162. -
First spacer rollers 170 are mounted on both sides of therotation shaft 152 of the conveyingroller unit 44, andsecond spacer rollers 174 corresponding to thefirst spacer rollers 170 are mounted on both sides of theshaft 160 of the separatingroller unit 46, to maintain a predetermined interval between the conveyingroller unit 44 and the separatingroller unit 46. - As shown in
FIG. 5 , atorsion spring 180 for providing an elastic force to the conveyingroller unit 46 to push the conveyingroller unit 46 to the separatingroller unit 44 is installed in the separatingroller unit 46. - That is, the
torsion spring 180 preferably includes a plate spring fixed between abracket 182 rotatably supported on theshaft 160 of the separatingroller unit 46 and themain body 6, for pushing the separatingroller unit 46 to the conveyingroller unit 44. - Here, the elastic force of the
torsion spring 180 for pushing the separatingroller unit 46 is set according to stiffness of themedia 150. That is, when themedia 150 have normal stiffness, the second conveyingrollers 156 and thesecond separating rollers 164 maintain the predetermined gaps T due to stiffness of themedia 150 passing between the first conveyingrollers 154 and thefirst separating rollers 162, and when themedia 150 have low stiffness, the force of thetorsion spring 180 is applied to the conveyingroller unit 44 to reduce the gaps between the second conveyingrollers 156 and thesecond separating rollers 164, thereby generating the frictional force to themedia 150. -
FIGS. 6 and 7 are operation status diagrams illustrating the media pick-up device in accordance with the present invention. - When the pick-up
roller 42 is rotated to transmit themedia 150 stored in themedia cassette 2 to the lower side direction, themedia 150 are conveyed between the conveyingroller unit 44 and the separatingroller unit 46, separated one by one, guided by themedia conveying device 10, and externally discharged through themedia discharge device 12. That is, the conveyingroller unit 44 is rotated, and the separatingroller unit 46 is at a stationary state or rotated in the opposite direction to the conveyingroller unit 44, to separate themedia 150 one by one. - When the
media 150 have normal stiffness, as shown inFIG. 6 , themedia 150 rub with thefirst separating rollers 162 by the overlaps Q between the first conveyingrollers 154 and thefirst separating rollers 162, and thus are separated one by one. Because themedia 150 have normal stiffness, thetorsion spring 180 overcomes the elastic force by stiffness of themedia 150, and the predetermined gaps T are maintained between the second conveyingrollers 156 and thesecond separating rollers 164. - In the case that the
media 150 have normal stiffness, when themedia 150 pass between the first conveyingrollers 154 and thefirst separating rollers 162, a separating force is generated between the first conveyingrollers 154 and thefirst separating rollers 162, to separate themedia 150 one by one. Because the gaps T between the second conveyingrollers 156 and thesecond separating rollers 164 are greater than thickness of themedia 150, the separating force is not generated between the second conveyingrollers 156 and thesecond separating rollers 164. - As illustrated in
FIG. 7 , when themedia 150 absorb moisture due to the humid area where the media dispenser is installed, or wet season like summer, stiffness of themedia 150 is reduced. Here, the separatingroller unit 46 moves to the conveyingroller unit 44 by the elastic force of thetorsion spring 180, to reduce the gaps T between the second conveyingrollers 156 and thesecond separating rollers 164. That is, the gaps T are maintained between 0.1 and 0.2 mm, thereby generating the frictional force to themedia 150. - As described above, when the
media 150 have low stiffness, themedia 150 generate the frictional force between the first conveyingrollers 154 and thefirst separating rollers 162 and between the second conveyingrollers 156 and thesecond separating rollers 164, and thus are accurately separated one by one. - The effects of the media pick-up device in accordance with the present invention will now be explained.
- When the media have normal stiffness, the media are separated one by one due to friction by the overlaps between the first conveying rollers and the first separating rollers. When the media have low stiffness, the first conveying rollers and the first separating rollers as well as the second conveying rollers and the second separating rollers are adhered to each other to separate the media. As a result, the media are accurately separated one by one, to improve performance of the media dispenser.
- As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the metes and bounds of the claims, or equivalence of such metes and bounds are therefore intended to be embraced by the appended claims.
