Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a feeding mechanism that is provided in a printing apparatus or a copying apparatus and feeds a medium by a feeding roller.
[0002]
[Prior art]
Conventionally, in a printing apparatus or copying apparatus, a hopping roller is pressed against a recording medium stored in a tray, and the hopping roller is rotated to feed the medium one by one from the tray for printing or copying. ing. The problem in reducing the size of the printing apparatus is the arrangement of the medium feeding path. The feeding path immediately after the hopping roller feeds the medium from the tray is a curved feeding path with a small curvature. As a result, the number of devices with a reduced installation area is increasing.
[0003]
A separation pad is pressed against the hopping roller, and the media fed from the tray is separated one by one by the separation pad. In particular, in a small apparatus, the hopping of the separation pad is performed in order to simplify the mechanism. There is a mechanism that does not provide a mechanism for pressing / releasing the roller but always keeps the separation pad in pressure contact with the hopping roller.
[0004]
If the pressing force of the separation pad against the hopping roller is too strong, an image stretch of the printed image on a thin medium and a drop shock when the end of the medium leaves the hopping roller appear on the print image. Therefore, the pressure contact force of the separation pad is set to an appropriate value so that such a phenomenon does not appear.
[0005]
[Problems to be solved by the invention]
However, in the conventional feeding mechanism, when printing on a thick medium, the thick medium is fed while abutting the leading edge of the thick medium against the feeding path having a small curvature. The load on the front end of the medium becomes large, and a feeding force that can overcome the load is required. The feeding force of the medium depends on the pressing force between the hopping roller and the medium, but if the pressing force of the separation pad against the hopping roller is set for a thin medium, a feeding force sufficient to feed a thick medium can be obtained. There were cases where it was not possible.
[0006]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention provides a feeding mechanism that presses a medium against a feeding roller and feeds the medium by rotation of the feeding roller, and swings along a feeding path through which the medium is fed.

It is a feature. Further, when the auxiliary pressure contact member swings, the amount of the medium wound around the feed roller is increased by changing the pressure contact angle of the separation pad to the feed roller of the separation pad. It is.

[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view showing a feeding mechanism according to the first embodiment of the present invention, and FIG. 2 is a perspective view showing an auxiliary pressure contact plate according to the first embodiment.
[0010]
In FIG. 1, a feeding mechanism 1 according to the first embodiment includes a medium tray 3 for stacking and storing media 2, a hopping roller 4 for feeding the media 2 one by one, and a separation pad 5 that is in pressure contact with the hopping roller 4. And a curved medium guide 6 for conveying the fed medium 2. The medium 2 stored in the medium tray 3 is pressed upward by pressing means (not shown), and the uppermost medium 2 is pressed against the hopping roller 4.
[0011]
The separation pad 5 is attached to a separation frame 7, and the separation frame 7 is supported by a spring 9 so as to be movable up and down. The spring 9 is supported by a support member 8. In the spring 9, the separation pad 5 is in pressure contact with the hopping roller 4. The separation pad 5 separates the medium 2 fed by the hopping roller 4 into one sheet. The medium guide 6 includes an inner guide 10 and an outer guide 11, and the guides 10 and 11 constitute a feeding path 16 having a small curvature. An auxiliary pressure contact plate 12 is provided on the outer guide 11.
[0012]
1 and 2, the auxiliary pressure contact plate 12 is provided so as to be swingable around the fulcrum part 13, and the left side of the fulcrum part 13 (downstream in the feeding direction of the medium 2) has substantially the same curvature as the outer guide 11. Abutment guide portion 14 is formed, and a protrusion 15 is formed on the right side of the fulcrum portion 13. The abutting guide part 14 is provided so as to protrude inward of the feeding path 16 relative to the outer guide 11 so that the tip of the medium 2 fed out by the hopping roller 4 abuts against the abutting guide part 14 before the outer guide 11. It has become. As shown in FIG. 3, a spring 17 is disposed outside the abutting guide portion 14, and the spring 17 presses the auxiliary pressure contact plate 12 to swing clockwise around the fulcrum portion 13. .
[0013]
Next, the operation of the first embodiment will be further described with reference to FIGS. 3 and 4 are side views showing the operation of the first embodiment. FIG. 3 shows a case where a thin medium is fed, and FIG. 4 shows a case where a thick medium is fed. First, a case where the medium 2 is a thin medium will be described.
[0014]
The uppermost medium 2 a among the media 2 a set on the medium tray 3 is pressed by the hopping roller 4. By rotating the hopping roller 4 in the clockwise direction, the uppermost medium 2 a is fed out and fed to the separation pad 5. The separation pad 5 separates the uppermost medium 2a from the second and subsequent media 2a, and the uppermost medium 2a is further fed by the hopping roller 4.
[0015]
At this time, the auxiliary pressure contact plate 12 is pressed to the position shown in FIG. 3 by the spring 17, and the protrusion 15 is in a position where the tip of the medium 2a can easily pass through the upper portion thereof. The auxiliary pressure contact plate 12 is stopped from swinging clockwise by the spring 17 at a position shown in FIG. 3 by a stopper (not shown).
[0016]
The tip of the separated medium 2 a hits the inside of the abutting guide portion 14 of the auxiliary pressure contact plate 12. Since the thin medium 2a has no rigidity, it is guided by the auxiliary pressure contact plate 12 and the outer guide 11 as it is, and further fed through the feeding path 16.
[0017]
Next, a case where a thick medium is fed will be described. The above-described operation is the same until the medium 2b is fed from the medium tray 3 by the rotation of the hopping roller 4 and further separated into one sheet by the separation pad 5. After passing through the separation pad 5, the tip of the thick medium 2 b hits the inside of the abutting guide portion 14 of the auxiliary pressure contact plate 12. Since the thick medium 2b has rigidity, the auxiliary pressure contact plate 12 swings around the fulcrum portion 13 in the counterclockwise direction in FIG. 4 against the pressing force of the spring 17 when the tip of the medium 2b hits. The pressing force of the spring 17 is set smaller than the pressing force of the medium when the thick medium having rigidity is abutted against the auxiliary pressure contact plate 12.
[0018]
As the auxiliary pressure contact plate 12 swings, the protrusion 15 of the auxiliary pressure contact plate 12 moves upward and approaches the hopping roller 4. Thereby, the amount by which the medium 2b is wound around the hopping roller 4 increases. That is, the winding amount θ2 of the thick medium 2b shown in FIG. 4 around the hopping roller 4 is larger than the winding amount θ1 of the thin medium 2a shown in FIG. As the winding amount increases, the medium 2b increases the feeding force by the hopping roller 4.
[0019]
The distance from the fulcrum part 13 serving as the center of oscillation to the position (power point) where the tip of the medium 2b abuts the inside of the abutment guide part 14 of the auxiliary pressure contact plate 12 is a protrusion on the auxiliary pressure contact plate 12. By setting the distance sufficiently long with respect to the position (working point) of the 15 in contact with the medium 2b, the force for lifting the protrusion 15 is increased by the principle of scissors.
[0020]
The swinging of the auxiliary pressure contact plate 12 stops when the inner side of the abutting guide part 14 is flush with the inner side 11a of the outer guide 11. This is the state shown in FIG. After the medium 2b hits the abutting guide portion 14, it is fed by the increased feeding force, the tip moves while sliding on the auxiliary pressure contact plate 12, and eventually the inner guide 10 as shown by the dotted line in FIG. It contacts the lower end 10a. From this point, the medium 2b enters the feeding path 16 having a small curvature. For this purpose, the medium 2b must be bent against rigidity. When the medium 2b starts to bend, the maximum feeding force is required. In the present embodiment, since the feeding force is increased by the action of the auxiliary pressure contact plate 12, the medium 2b is bent and the feeding path 16 is fed.
[0021]
Once the medium 2b is bent, it is fed even with a feeding force that is not so large. Therefore, after the leading end of the medium 2b enters the feeding path 16, the force with which the medium 2b presses the auxiliary pressure contact plate 12 decreases, and the auxiliary pressure contact plate 12 returns to the original position (position shown in FIG. 3) to return to the medium 2b. Even if the feeding force with respect to becomes the original size, the medium 2b continues to be fed.
[0022]
As described above, according to the first embodiment, when the thin medium 2a is fed, the feeding force is not increased, and only when the thick medium 2b is fed, the feeding force by the hopping roller 4 is increased. Therefore, it is possible to perform appropriate feeding according to the thickness of the medium.
[0023]
Next, a second embodiment will be described. FIG. 5 is a side view showing the feeding mechanism of the second embodiment. In FIG. 5, in the feeding mechanism of the second embodiment, an auxiliary pressure contact plate 21 is provided so as to be able to swing around a fulcrum portion 22, and the auxiliary pressure contact plate 21 has an abutment guide portion 23, and vice versa. An auxiliary roller 24 is rotatably provided on the side. As with the auxiliary pressure contact plate 12 of the first embodiment, the auxiliary pressure contact plate 21 swings counterclockwise around the fulcrum portion 22 when the tip of the thick medium 2b hits the abutting guide portion 23. Then, the auxiliary roller 24 moves upward. The auxiliary roller 24 is in pressure contact with the hopping roller 4 through the medium 2b. Other configurations are the same as those of the first embodiment.
[0024]
Next, a case where a thick medium is fed in the second embodiment will be described. The medium 2b is fed out from the medium tray 3 by the rotation of the hopping roller 4 and further separated into one sheet by the separation pad 5. After passing through the separation pad 5, the tip of the thick medium 2 b hits the inside of the abutting guide portion 23 of the auxiliary pressure contact plate 21. Since the thick medium 2b has rigidity, the auxiliary pressure contact plate 21 swings around the fulcrum portion 22 in the counterclockwise direction in FIG. 5 against the pressing force of the spring 17 when the tip of the medium 2b hits. The pressing force of the spring 17 is set smaller than the pressing force of the medium when the thick medium having rigidity is abutted against the auxiliary pressure contact plate 21.
[0025]
As the auxiliary pressure contact plate 21 swings, the auxiliary roller 24 of the auxiliary pressure contact plate 21 moves upward and comes into pressure contact with the hopping roller 4 via the medium 2b. Thereby, the amount by which the medium 2b is wound around the hopping roller 4 increases. As the winding amount increases, the medium 2b increases the feeding force by the hopping roller 4.
[0026]
The swinging of the auxiliary pressure contact plate 21 stops when the inside of the abutment guide portion 23 is flush with the inside 11a of the outer guide 11. After the medium 2b hits the abutting guide portion 23, the medium 2b is fed by the increased feeding force, the tip moves while sliding on the auxiliary pressure contact plate 21, and enters the feeding path 16 having a small curvature. Here, the medium 2b starts to bend due to the increased feeding force and is fed through the feeding path 16.
[0027]
As described above, according to the second embodiment, when the thick medium 2b is fed, the feeding force is increased by the auxiliary roller 24 of the auxiliary pressing plate 21 being pressed against the hopping roller 4 via the medium 2b. Therefore, as compared with the first embodiment, when the amount of wrapping around the hopping roller 4 is the same, the feeding force can be further increased as compared with the first embodiment.
[0028]
Next, a third embodiment will be described. FIG. 6 is a side view showing the feeding mechanism of the third embodiment. In FIG. 6, in the feeding mechanism of the third embodiment, an auxiliary pressure contact plate 31 is provided so as to be swingable around a fulcrum portion 32, and the auxiliary pressure contact plate 31 has an abutment guide portion 33. On the opposite side of 32, a support portion 34 for supporting the spring 9 is formed. Similar to the auxiliary pressure contact plate 12 of the first embodiment, the auxiliary pressure contact plate 31 swings counterclockwise around the fulcrum portion 32 when the leading end of the thick medium 2b hits the abutting guide portion 33. Then, the support part 34 moves upward. Other configurations are the same as those of the first embodiment.
[0029]
Next, a case where a thick medium is fed in the third embodiment will be described. The medium 2b is fed out from the medium tray 3 by the rotation of the hopping roller 4 and further separated into one sheet by the separation pad 5. After passing through the separation pad 5, the tip of the thick medium 2 b hits the inside of the abutting guide portion 33 of the auxiliary pressure contact plate 31. Since the thick medium 2b has rigidity, the auxiliary pressure contact plate 31 swings counterclockwise in FIG. 6 around the fulcrum portion 32 against the pressing force of the spring 17 when the tip of the medium 2b hits. The pressing force of the spring 17 is set to be smaller than the pressing force of the medium when the thick medium having rigidity is abutted against the auxiliary pressure contact plate 31.
[0030]
As the auxiliary pressure contact plate 31 swings, the support portion 34 moves upward and the spring 9 is lifted. The lifted spring 9 increases the force for pressing the separation pad 5 against the hopping roller 4 via the separation frame 7. Thereby, the force by which the medium 2b is pressed against the hopping roller 4 is increased, and the feeding force of the medium 2b by the hopping roller 4 is increased.
[0031]
The swinging of the auxiliary pressure contact plate 31 stops when the inside of the abutting guide portion 33 is flush with the inside 11a of the outer guide 11. After the medium 2b hits against the abutting guide portion 33, the medium 2b is fed by the increased feeding force, the tip moves while sliding on the auxiliary pressure contact plate 31, and enters the feeding path 16 having a small curvature. Here, the medium 2b starts to bend due to the increased feeding force and is fed through the feeding path 16.
[0032]
As described above, according to the third embodiment, when the thick medium 2b is fed, the support portion 34 of the auxiliary pressure contact plate 31 lifts the spring 9 that presses the separation pad 5, and the separation pad 5 is the hopping roller. 4 is strengthened, the feeding force of the medium 2b by the hopping roller 4 is increased. As described above, in the present embodiment, the feeding force is increased without bringing the auxiliary pressure contact plate 31 into direct contact with the medium 2b. Therefore, the feeding force can be increased without causing wrinkles or damage to the medium due to contact with the medium 2b. Can be increased.
[0033]
Next, a fourth embodiment will be described. FIG. 7 is a side view showing the feeding mechanism of the fourth embodiment. In FIG. 7, in the feeding mechanism of the fourth embodiment, an auxiliary pressure contact plate 41 is provided so as to be able to swing around a fulcrum portion 42. The auxiliary pressure contact plate 41 has an abutment guide portion 43, and the fulcrum portion. An engaging portion 44 is formed on the opposite side of 42. On the separation frame 7 that supports the separation pad 5, a protrusion 45 is formed at a position where it can engage with the engagement portion 44. The protrusions 45 are formed on both sides of the hopping roller 4.
[0034]
The separation frame 7 is supported by a spring 9 so as to be movable in the vertical direction and swingable. Similar to the auxiliary pressure contact plate 12 of the first embodiment, the auxiliary pressure contact plate 41 swings counterclockwise around the fulcrum portion 42 when the leading end of the thick medium 2b hits the abutting guide portion 43. Then, the engaging portion 44 moves upward. Other configurations are the same as those of the first embodiment.
[0035]
Next, the operation of the fourth embodiment will be further described with reference to FIGS. 8 and 8 are side views showing the operation of the fourth embodiment. FIG. 8 shows a case where a thin medium is fed, and FIG. 9 shows a case where a thick medium is fed. First, a case where a thin medium is fed will be described.
[0036]
The uppermost medium 2 a among the media 2 a set on the medium tray 3 is pressed by the hopping roller 4. By rotating the hopping roller 4 in the clockwise direction, the uppermost medium 2 a is fed out and fed to the separation pad 5. The separation pad 5 separates the uppermost medium 2a from the second and subsequent media 2a, and the uppermost medium 2a is further fed by the hopping roller 4.
[0037]
At this time, the auxiliary pressure contact plate 41 is pressed to the position shown in FIG. 8 by the spring 17 and is stopped at this position, and the medium 2 a passes through the upper part of the protrusion 45. The tip of the separated medium 2 a hits the inside of the abutting guide portion 14 of the auxiliary pressure contact plate 12. Since the thin medium 2a has no rigidity, it is guided by the auxiliary pressure contact plate 12 and the outer guide 11 as it is, and further fed through the feeding path 16.
[0038]
Next, a case where a thick medium is fed will be described. The above-described operation is the same until the medium 2b is fed from the medium tray 3 by the rotation of the hopping roller 4 and further separated into one sheet by the separation pad 5. After passing through the separation pad 5, the tip of the thick medium 2 b passes above the protrusion 45 and hits the inside of the abutment guide 43 of the auxiliary pressure contact plate 41. Since the thick medium 2b has rigidity, the auxiliary pressure contact plate 41 is counterclockwise in FIG. 9 centering on the fulcrum part 42 against the pressing force of the spring 17 when the tip of the medium 2b hits the abutting guide part 43. Swing in the direction. The pressing force of the spring 17 is set smaller than the pressing force of the medium when the thick medium having rigidity is abutted against the auxiliary pressure contact plate 41.
[0039]
As the auxiliary pressure contact plate 41 swings, the engaging portion 44 of the auxiliary pressure contact plate 41 moves upward, engages with the protrusion 45 formed on the separation frame 7 and pushes up the protrusion 45. As a result, the separation frame 7 rises on the left side (downstream side in the feed direction) in FIG. 9 and falls on the right side (upstream side in the feed direction). Due to the swing of the separation frame 7, the amount of the medium 2 b newly wound around the hopping roller 4 on the downstream side in the feeding direction of the separation pad 5 increases. That is, the winding amount θ3 of the thick medium 2b shown in FIG. 9 around the hopping roller 4 is larger than the winding amount θ1 of the thin medium 2a shown in FIG. As the winding amount increases, the medium 2b increases the feeding force by the hopping roller 4.
[0040]
The swinging of the auxiliary pressure contact plate 41 stops when the inside of the abutment guide portion 43 is flush with the inside 11a of the outer guide 11. This is the state shown in FIG.
After the medium 2b hits the abutting guide portion 43, the medium 2b is fed by the increased feeding force, the tip moves while sliding on the auxiliary pressure contact plate 41, and the medium 2b eventually enters the feeding path 16 having a small curvature. However, since the feeding force of the medium 2b is increased due to the rise of the protrusion 45, the medium 2b is bent and the feeding path 16 is fed.
[0041]
As described above, according to the fourth embodiment, when the thick medium 2b is fed, the angle at which the protrusion 45 is raised by the swinging of the auxiliary pressure contact plate 41 and is pressed against the hopping roller 4 of the separation pad 5. Is further deepened on the downstream side in the feeding direction, so that the feeding force of the medium 2b by the hopping roller 4 is increased without increasing the pressure contact force to the hopping roller 4, and thus the thickness of the medium 2 is increased. Regardless of the concern about image expansion and hopping loss shock, the medium feeding force can be increased.
[0042]
【The invention's effect】
As described above in detail, according to the present invention, the auxiliary pressure contact plate is provided so as to be swingable along the medium feeding path, and the tip of the thick thick medium abuts against the auxiliary pressure contact plate, thereby assisting pressure contact plate. Oscillates, and the oscillation increases the amount of winding of the medium around the hopping roller, or increases the medium pressure contact force against the hopping roller, thereby increasing the feeding force of the thick medium. Accordingly, even when a thick medium is fed through a feeding path having a small curvature, a feeding force capable of feeding can be obtained.
