There was a problem that it became impossible to carry.

In order to solve such a problem, for example, as shown in FIG. 8, the pulley 12 next to the pulley 11 is
A long hole 18 extending in the vertical direction is provided at a position closer to the pulley 11 so as to be vertically movable, and the pulley 12 is constantly pressed downward by a spring 19 to cope with a small number of media M. It is also possible to make it possible. However, with such a configuration, since the inclination angle of the belt 13 between the pulleys 11 and 12 becomes too large, a problem occurs when a large number of mediums M are present, that is, as shown in FIG. Inevitably, since the lower medium M is conveyed prior to the upper medium M, the stacking shape of the medium M is greatly collapsed, and a problem such as a jam is likely to occur during the conveyance. .

In view of the above conventional problems, it is an object of the present invention to enable smooth transportation regardless of the number of media stored in the pool section.

[0009]

According to the present invention, a pool section for accommodating a plurality of sheet-like media is provided, and a plurality of media accommodated in the pool section are conveyed while being sandwiched in the stacking direction. The medium transport mechanism including the transport unit is characterized by the following points. That is, it is provided with an interval setting mechanism that sets the interval (open amount) in the stacking direction at the medium receiving part from the pool part in the transport part to a width corresponding to the number of media to be transported.

As the interval setting mechanism, for example, a cam, a lever or the like may be used, and various mechanisms may be adopted as long as the open amount can be set according to the number of media.

[0011]

When the number of media is small, the open amount is set small corresponding to the small number, and when the number of media is large, the open amount is set large corresponding to the large number. Therefore, regardless of whether the number of media is small or large, an open amount suitable for that is set, and smooth delivery and conveyance from the pool section is possible regardless of the number of media.

The upper transport system U _{11 is} also configured to be vertically movable, and is constantly urged downward by, for example, a spring (not shown) or the like, and the lower transport system L _{11 is}
With the upward movement of the medium M, the uppermost surface of the medium M on the medium M is abutted and pushed up. That is, the upper and lower transport systems U ₁₁ and L ₁₁ can accommodate the medium M with the medium M sandwiched therebetween, and the vertical interval between the upper and lower transport systems U ₁₁ and L ₁₁ is equal to the number of medium M accommodated. It is configured to be variable according to the above.

The transport section F has a plurality of pulleys 31, 32, 33 arranged along the transport direction of the medium M (direction of arrow A).

By being fitted in, it can move up and down within a certain range and is always urged downward by the spring 45. The cam 42 has a substantially elliptical peripheral portion, and is rotatable in the arrow E direction around the fulcrum 46. An engaging portion 47 that engages with the rotation shaft of the pulley 21 of the upper transport system U ₁₁ of the pool portion P is provided at the end of the cam 42, and the cam 42 is moved in the direction of the arrow as the upper transport system U ₁₁ moves up and down. It is configured to rotate in the E direction, and further, with the rotation, the elliptical peripheral edge portions come into contact with the respective rotary shafts of the pulleys 31 and 32 and vertically move.

The operation of the medium transporting mechanism having the above-described structure during medium transport will be described below with reference to FIGS. 1 and 2. First, when accommodating the media M one by one from the outside to the pool section P via the transport section F, as shown in FIG. 1, both the upper and lower transport systems U ₁₁ and L ₁₁ are downward. The cam 42 is moved to the position,
Therefore, the pulleys 31 and 32 are in contact with the pulleys 35 and 36 therebelow via the belts 34 and 38. In this state, arrow A is fed from the left side of the figure by the transport unit F.
The mediums M, which have been conveyed one by one in the opposite direction, are sequentially stacked and stored on the lower conveyance system L ₁₁ of the pool section P.

It is raised to the same plane as the lower transport system L ₁₂ . Lower transport system L at this time
The rising position of ₁₁ is regulated by, for example, detecting the position by a sensor or the like (not shown). When the lower transport system L ₁₁ rises in this way, the upper transport system U ₁₁ is pushed up by a thickness corresponding to the number of media M loaded on the lower transport system L ₁₁ , that is, the number of loaded media M is increased. less when the upper conveying system U ₁₁ as shown in FIG. 2 (a) increased slightly while the upper conveyor system as if the number of stacked sheets of the medium M is large shown in FIG. 2 (b) U ₁₁ Greatly rises.

As shown in FIG. 2 (a), when the medium M is a small number, the upper transport system U ₁₁ also has a low raised position as described above. The cam 42 rotates only slightly in the clockwise direction, so that the peripheral portion of the cam 42 pushes up the pulley 31 of the transport unit F only slightly. As a result, the open amount d, which is the distance between the pulley 31 and the pulley 35 below it, is set to a small amount according to the number of media M. In this state, the upper and lower transport systems U ₁₁ , L ₁₁ of the pool section P

On the other hand, when the medium M is a large number as shown in FIG. 2 (b), since the upper transport system U ₁₁ has a high raised position as described above, the cam 42 which rotates in conjunction with this is moved. Also, the cam 42 pivots largely in the counterclockwise direction, so that the peripheral edge of the cam 42 pushes both the pulley 31 and the pulley 32 of the transport unit F largely. Of course, depending on the shape of the cam 42, the pulley 3
The pulley 32 is located lower than the position 1. As a result, the open amount d is set to a large amount according to the number of media M. In this state, the upper and lower transport systems U ₁₁ ,
By driving the upper and lower transport systems U ₁₂ , L ₁₂ of L ₁₁ and the transport unit F, a large number of media M can be collectively nipped and transported in the direction of arrow A smoothly.

As described above, according to this embodiment,
Whether the number of media M to be transported is small or large, a suitable open amount d is automatically set, so that smooth transfer and transport from the pool section P is possible regardless of the number of media. Is possible.

Although the pulley 32 is also pushed up by the cam 42 in the above embodiment, the lower end of the long hole 44 pushes up the pulley 32 as the bracket 41 is rotated by the cam 42 pushing up the pulley 31. It may be configured.

In the above embodiment, the engaging portion 4 of the cam 42 is used.
7 is configured to engage with the pulley 21 of the upper transport system U ₁₁ , but the cam 42 may be engaged with any portion of the pool portion P as long as the position thereof varies depending on the number of media. Absent.

Next, FIG. 3 shows a second part of the medium carrying mechanism of the present invention.
It is a schematic diagram of an example. Although the elliptical cam 42 is used in the first embodiment, a substantially linear cam 51 is used in place of the cam 42 in the second embodiment, and the interval setting mechanism D ₂ is used.
The other configurations are similar to those of the first embodiment. The cam 51 is rotatable around a fulcrum 52 in the direction of arrow E, and an engaging portion 53 that engages with the rotary shaft of the pulley 21 of the upper transport system U ₁₁ of the pool portion P is provided at the end thereof. The cam 51 rotates in the direction of the arrow E as the upper transport system U ₁₁ moves up and down, and the recesses 54 and 55 provided at the upper edge of the cam 51 cause the pulleys 31 and 32 to rotate in accordance with the rotation. It comes into contact with each of the rotating shafts and moves up and down.

Since the cam 51 having such a structure has the same action as that of the elliptical cam 42, the same effect as that of the first embodiment can be obtained in this embodiment. Next, FIG.
