Referring to
The cassette 10 comprises a pickup roller 11 that may separate and transfer the aligned medium M one by one to a medium transferring path.
One or more transfer rollers 13a and 13b are disposed on the medium transferring path. For example, a plurality of the transfer rollers 13a and a plurality of the transfer rollers 13b may be disposed on the medium transferring path. The transfer rollers 13a and 13b comprise first transfer rollers (also denoted by 13a) and second transfer rollers (also denoted by 13b) disposed at the downstream side of the first transfer rollers 13a in a medium transferring direction.
The transfer rollers 13a and 13b rotate to transfer the medium M along the medium transferring path. Thus, when contacting the transfer rollers 13a and 13b, the medium M receive torque therefrom, and move forward on the medium transferring path. The transfer rollers 13a and 13b may be disposed on at least one of the upper and lower sides of the medium transferring path.
The transfer rollers 13a and 13b are installed on transfer shafts 20a and 20b that rotate in a position perpendicular to side guides 30 to be described later, so as to move the medium M forward along the medium transferring path defined by the side guides 30. One or more of the transfer shafts 20a and 20b may be provided to the medium transferring apparatus. One of the transfer shafts 20a and 20b may be provided with one or more of the transfer rollers 13a or 13b.
Idle rollers 13a′ and 13b′ are disposed on the opposite side of the medium transferring path to the transfer rollers 13a and 13b. Thus, the idle rollers 13a′ and 13b′ rotate according to rotations of the transfer rollers 13a and 13b, to thereby help the transfer rollers 13a and 13b transfer the medium M.
The medium transferring apparatus comprises one or more aligning rollers 14a and 14b for aligning the medium M while being transferred. For example, a plurality of the aligning rollers 14a and a plurality of the aligning rollers 14b may be provided on the medium transferring apparatus. The aligning rollers 14a and 14b comprise first aligning rollers (also denoted by 14a) and second aligning rollers (also denoted by 14b) disposed at the downstream side of the first aligning rollers 14a in the medium transferring direction.
The aligning rollers 14a and 14b rotate in a position inclined at a certain angle from the medium transferring direction. That is, a rotation direction of the aligning rollers 14a and 14b is inclined at a certain angle from that of the transfer rollers 13a and 13b, to thereby align the medium M on one of the side guides 30.
To this end, the centers of the aligning rollers 14a and 14b are fixed to aligning shafts 21a and 21b that are not perpendicular to the side guides 30 and are inclined at a certain angle therefrom. That is, the aligning shafts 21a and 21b are inclined at a certain angle from the transfer shafts 20a and 20b. The aligning shafts 21a and 21b may be provided with one or more of the aligning rollers 14a and 14b. When the aligning shafts 21a and 21b are provided with a plurality of the aligning rollers 14a and 14b, the aligning rollers 14a and 14b are parallel to one another.
The aligning rollers 14a and 14b receive torque from the aligning shafts 21a and 21b to move the medium M. That is, when the medium M contact the aligning rollers 14a and 14b, since the aligning rollers 14a and 14b rotate in a position inclined at a certain angle, the medium M moves over a certain distance in the medium transferring direction, and also moves to one of the side guides 30. In other words, the moving of the medium M by the aligning rollers 14a and 14b has a vector component parallel to the medium transferring direction and a vector component perpendicular thereto. This is because the aligning rollers 14a and 14b are inclined at a certain angle, and are not parallel and perpendicular to the medium transferring direction, that is, the rotation direction of the transfer rollers 13a and 13b.
A rotation direction of the aligning rollers 14a and 14b in a region where the aligning rollers 14a and 14b contact the medium M is inclined at an angle less than 90°, to the left or right side (to the left side in
Idle rollers 14a′ and 14b′ are disposed on the opposite side of the medium transferring path to the aligning rollers 14a and 14b. Thus, the idle rollers 14a′ and 14b′ rotate according to rotations of the aligning rollers 14a and 14b, to thereby help the aligning rollers 14a and 14b transfer the medium M.
Transfer belts 16 may be disposed on the medium transferring path. The transfer belts 16 rotate in the medium transferring direction to move the medium M transferred through the transfer rollers 13a and 13b and the aligning rollers 14a and 14b. Each of the transfer belts 16 is wound around at least two belt rollers 15. The transfer belts 16 extend in the longitudinal direction of the side guides 30. To this end, the belt rollers 15 are fixed to rotation shafts 22 perpendicular to the side guides 30.
The side guides 30 are disposed at the left and right sides of the medium transferring path provided with the transfer rollers 13a and 13b and the aligning rollers 14a and 14b, to limit horizontal movements except for the movement in the medium transferring direction, thereby preventing a removal of the medium M from the medium transferring path. The side guides 30 are parallel to each other, and guide the medium M to the medium transferring path. The distance between the side guides 30 is greater by a certain amount than the width of the medium M (the length of the medium M in a direction perpendicular to the medium transferring direction). As shown in
The transfer rollers 13a and 13b, the aligning rollers 14a and 14b, and the transfer belts 16 are disposed all between the side guides 30 to transfer the medium M in the medium transferring direction within the medium transferring path in which the side guides 30 guide the medium M.
The medium transferring apparatus may comprise upper/lower guides 40 disposed at the upper and lower sides of the medium transferring path. The upper/lower guides 40 limit the vertical movement of the medium M to prevent the removal of the medium M from the medium transferring path.
The upper/lower guides 40 may comprise opposite parts to each other. That is, the upper/lower guides 40 may comprise an upper guide and a lower guide. The distance between the upper guide and the lower guide may depend on the thickness of the medium M. As shown in
As shown in
Thus, the medium M are surrounded and guided by the side guides 30 and the upper/lower guides 40, and are transferred in the medium transferring direction by the transfer rollers 13a and 13b, the aligning rollers 14a and 14b, and the transfer belts 16 through the first openings 40a and 40a′, the second openings 40b and 40b′, and the third openings 40c. Since the aligning rollers 14a and 14b move the medium M to one of the side guides 30 as described above, the medium M are aligned all on one of the left and right sides (on the left side in
That is, the aligning rollers 14a and 14b align the medium M such that a surface of the medium M contacts one of the side guides 30, and thus, the transferred medium M are stacked evenly in their width direction. When each of the aligning rollers 14a and 14b is provided in plurality, the aligning rollers 14a or 14b are inclined in the same direction.
The process that the medium transferring apparatus transfers the medium M will now be described in more detail with reference to
When the medium M enter the medium transferring path, the medium M may lean left or right between the side guides 30 having the distance greater than the width of the medium M, or be disposed in the middle therebetween as shown in
When the medium M enters the medium transferring path, and the front end of the medium M passes on the transfer roller 13a, the medium M is transferred by the rotation of the transfer roller 13a, in the medium transferring direction, that is, in the direction parallel to the side guides 30. Then, the front end of the medium M enters the aligning roller 14a. The aligning roller 14a moves the front end of the medium M to the left side of
When the aligning roller 14a and the transfer roller 13a have the same rotation speed, since the aligning roller 14a is inclined from the transfer roller 13a, a transferring speed of the aligning roller 14a in the medium transferring direction is slower than that of the transfer roller 13a. Thus, when the front end of the medium M is on the aligning roller 14a, and the rear end of the medium M is on the transfer roller 13a, the medium M may also be curled in its longitudinal direction (in the medium transferring direction).
As such, since the medium M may be curled, a distance h between the upper/lower guides 40 may be determined based on a curl height between the aligning roller 14a or 14b and the transfer roller 13a or 13b.
The distance between the aligning roller 14a or 14b and the transfer roller 13a or 13b can be adjusted to decrease a curl height of the medium M, thereby protecting the medium M. That is, when the distance between the aligning roller 14a or 14b and the transfer roller 13a or 13b is increased, the curl height of the medium M can be decreased. The curl height of the medium M can be less than the distance h between the upper/lower guides 40 by adjusting the distance h between the upper/lower guides 40 and the distance between the aligning roller 14a or 14b and the transfer roller 13a or 13b.
After the medium M is transferred by the transfer rollers 13a and 13b, a side surface of the medium M is brought into contact with one of the side guides 30 by the aligning rollers 14a and 14b. Then, the medium M is transferred to the transfer belts 16. Since force from the transfer belts 16 to the medium M is smaller than that of the transfer rollers 13a and 13b or the aligning rollers 14a and 14b, a curl formed at the transfer rollers 13a and 13b or the aligning rollers 14a and 14b is removed at the transfer belts 16. In this state, the medium M are aligned all on one of the side guides 30.
Accordingly, since the medium M are aligned in their width direction before being stacked, a staked state of the medium M can be improved.
When the transfer rollers 13a and 13b and the aligning rollers 14a and 14b have the same rotation speed and the same roller size, the aligning rollers 14a and 14b may be disposed at the upstream side of the transfer rollers 13a and 13b in the medium transferring direction, that is, the medium M may contact the aligning rollers 14a and 14b earlier. In this case, when the rear end of the medium M is caught on the aligning roller 14a or 14b, and the front end of the medium M enters the transfer roller 13a or 13b, the transferring speed of the transfer rollers 13a and 13b in the medium transferring direction is faster than that of the aligning rollers 14a and 14b, the medium M may be torn by a difference between the transferring speeds.
Thus, when the transfer rollers 13a and 13b change their positions with the aligning rollers 14a and 14b, the rotation speed of the transfer rollers 13a and 13b may be adjusted to be slower than that of the aligning rollers 14a and 14b, thereby preventing damage to the medium M.
When the transfer rollers 13a and 13b and the aligning rollers 14a and 14b are provided, the distance between the aligning roller 14a and the transfer roller 13b disposed at the downstream side of the aligning roller 14a may be increased to prevent the medium M from being simultaneously caught on both the aligning roller 14a and the transfer roller 13b. Particularly, when the aligning roller 14a is disposed between the first and second transfer rollers 13a and 13b, the distance between the aligning roller 14a and the second transfer roller 13b may be equal to or greater than the length of the medium M in the medium transferring direction.
Hereinafter, a medium transferring apparatus according to another embodiment will now be described with reference to the accompanying drawings.
Referring to
A rotation direction of the first aligning rollers 52a and 52b is inclined at a certain angle from that of the second aligning rollers Ma and 54b, to thereby align medium M on one of two side guides 80. That is, the first aligning rollers 52a and 52b are inclined at a certain angle to the second aligning rollers Ma and 54b with respect to the medium transferring direction. First aligning shafts 71 coupled to the first aligning rollers 52a and 52b are separated from second aligning shafts 72 coupled to the second aligning rollers Ma and Mb. The second aligning shafts 72 are parallel to transfer shafts 65 of the transfer roller 60. The first aligning shafts 71 are inclined at a certain angle from the second aligning shafts 72 and the transfer shafts 65.
An interaction between the medium M and the aligning roller 50 when the medium M passes on the aligning roller 50 will now be described. Referring to
The transfer roller 60 as well as the aligning roller 50 is disposed on the medium transferring path, and is disposed at the downstream side of the aligning roller 50 in the medium transferring direction. The transfer roller 60 comprises one or more rollers that are arrayed in a straight line in the direction perpendicular to the medium transferring direction. Although two rollers 62a and 64a constitute one of the transfer rollers 60 as shown in
The transfer roller 60 rotates in the medium transferring direction, to thereby move the medium M. At this point, the transfer roller 60 receives the medium M curled while passing on the aligning roller 50. To uncurl the medium M toward a medium aligning side, frictional force and pressure applied to the medium M by the roller 64a disposed at the medium aligning side may be less than those applied by the roller 62a as illustrated in
That is, the medium transferring direction is from the lower side of
Since the medium M is uncurled in the medium aligning direction, even though the medium M contacts the side guide 80, folding of the medium M can be prevented.
The medium transferring apparatus may comprise a plurality of transfer belts 76 and a plurality of belt rollers 75 rotating the transfer belts 76 in the medium transferring direction.
