DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a medium recovery device and a printing device for recovering a medium including a sheet and a booklet.

[0002]

2. Description of the Related Art Heretofore, there has been a printing apparatus which prints information on a booklet such as a passbook, prints information on roll paper in some cases, and then cuts and issues a sheet of a predetermined length. An example of such a printing device is a printing device used in an automatic teller machine. In such a printing apparatus, when a customer forgets to take a booklet or sheet on which information is printed, the booklet or sheet is collected in a medium collection box. FIG. 3 shows that the sheet 1 and the booklet 2
7 shows a state in which the medium is collected in the medium collection storage 25.

[0003]

By the way, the roll paper before being cut into one sheet unit is wound in a roll shape, so that the curl remains. Although this winding habit does not cause much problem when the roll paper has a large winding diameter at the beginning of use, the winding habit remains strong because the winding diameter decreases as it approaches the winding core. Thus, when the sheet 1 from which the roll paper has been cut is collected in the medium collection box 25, the rear end thereof is
It is released from 6,27 and warps.

When the sheet 1 is warped in this manner, the positions of the leading end and the trailing end cannot be regulated, so that the medium collection storage 25
Position in the transport direction at
Also, the amount of warpage from the bottom surface 28 of the fifth member 5 is uneven at the front end and the rear end, and the posture is not stable. Thus, it is difficult to orderly stack the sheets 1 in the medium recovery storage 25.

[0005] For example, when the sheet 1 is collected in the medium collection box 25 with the concave surface warped upward, the sheet 1 advances to the medium collection box 25 with its front end warped upward, and the rear end is then collected. Since the sheet 1 in the medium collection box 25 is warped upward when released from the rollers 26 and 27, the position and the posture of the sheet 1 in the medium collection box 25 are not determined.

Thus, for example, as shown in FIG. 3A, there are a sheet 1b pushed out in a sheet conveying direction by a sheet 1a collected later, and a sheet 1c pushed in a direction opposite to the sheet conveying direction. For example, the position and posture of the seat 1 are disturbed.

FIG. 3 shows a state in which the posture of the seat 1 is disturbed.
As shown in (b), when the booklet 2 with a strong stiffness is collected later, the sheet 1 may be crushed and bent by the booklet 2. In such a state, the medium collection storage 25
It is difficult to take out the sheet 1 from the sheet 1 and the sheet 1 may be torn.

This problem can be improved to some extent by providing a plurality of medium collection boxes to collect the sheets 1 and the booklet 2 separately. However, the apparatus is increased in size and the sheet 1 and the booklet 2 are collected. Therefore, there is a problem that the structure becomes complicated because it is necessary to switch the transport route.

SUMMARY OF THE INVENTION It is an object of the present invention to enable an orderly collection of sheets while keeping the apparatus small and simple.

[0010]

According to a first aspect of the present invention, there is provided a medium collection device comprising: a collection passage for collecting at least a sheet and a booklet cut from roll paper; and a medium collection storage connected to an exit side of the collection passage. A medium conveying member provided in the collection passage for collecting the medium in the medium collection storage, a medium pressing member provided to be able to approach and separate from the bottom surface of the medium collection storage, and And urging means for urging the medium holding member toward the bottom surface of the medium collection box with an urging force that is stronger than the waist strength of the booklet.

Therefore, since the sheet collected in the medium collection box is pressed by the medium holding member, floating and warping from the bottom of the medium collection box are suppressed. Therefore, even if the booklet is collected on the collected sheet, the sheet below the booklet is not bent. When the booklet is collected, the medium holding member can be retracted upward, so that a strong booklet does not break.

According to a second aspect of the present invention, there is provided a printing apparatus comprising: a roll paper storage section for storing roll paper; a roll paper transport path connected to the roll paper storage; and a cutting means for cutting the roll paper into sheet units. 2. The medium conveyance path according to claim 1, wherein the medium conveyance path is configured to convey the cut sheet, printing means provided in at least one of the roll paper conveyance path and the medium conveyance path, and the medium conveyance path. A medium recovery device.

Therefore, similarly to the first aspect of the present invention, since the sheet collected in the medium collection box is pressed by the medium pressing member, floating and warping from the bottom of the medium collection box are suppressed. Therefore, even if the booklet is collected on the collected sheet, the sheet below the booklet is not bent. When the booklet is collected, the medium holding member can be retracted upward, so that a strong booklet does not break.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a vertical sectional side view showing a state where a medium collecting device is mounted on a printing apparatus, and FIG. 2 is a vertical sectional side view showing a medium collecting device and a medium collecting state.

First, the configuration of the printing device P will be described with reference to FIG. Reference numeral 10 denotes a printing apparatus main body. The printing apparatus main body 10 is provided with a medium transport path 12 extending from the front 11 to the back. A plurality of pairs of transport rollers 13 are arranged in the medium transport path 12, and a platen 14 and a print head (impact dot printer head) 15 as a printing unit are provided. The print head 15 is mounted on a carriage (not shown) that is driven to reciprocate in a direction (perpendicular to the paper) perpendicular to the medium transport direction (left-right direction on the paper).

A roll paper transport path 17 extending from a roll paper storage section 16 formed on the back side of the printing apparatus main body 10 to the front face 11 is joined to a portion of the medium transport path 12 behind the print head 15. I have. Roll paper 18 is supported by the roll paper storage unit 16. A plurality of pairs of transport rollers 19, a platen 20, a printing head (thermal head) 21 as printing means pressed against the platen 20, and a rotary cutter 2 as cutting means are provided in the roll paper transport path 17.
2 are arranged. The medium conveyed through the medium conveyance path 12 includes the sheet 1 and the booklet (passbook) 2 shown in FIG. A table 23 for inserting the booklet 2 into the medium transport path 12 or temporarily placing the sheet 1 or the booklet 2 discharged from the medium transport path 12 is formed on the front surface 11 of the printing apparatus main body 10. Have been.

The printing apparatus main body 10 is provided with a medium collection device A. The medium collection device A includes a collection path 24 connected to the inner side of the medium conveyance path 12 described above,
The medium recovery storage 25 connected to the outlet side of the recovery passage 24
A collection roller 26, 27 serving as a medium conveyance member opposed to the collection passage 24, a medium holding member 29 provided to be able to approach and separate from a bottom surface 28 of the medium collection storage 25, and a medium holding member The member 29 is attached to the bottom surface 2 of the medium collection box 25.
And a torsion coil spring 30 as an urging means for urging the spring toward the position 8. The roll paper transport path 17 is connected at the connection between the medium transport path 12 and the recovery path 24.

In the present embodiment, the medium holding member 2
9 is rotatably supported by support shafts 31 provided on both side walls of the medium recovery storage 25, and a torsion coil spring 30 is wound around the support shaft 31. The torsion coil spring 30 connects the medium holding member 29 to the bottom surface 2 of the medium collection box 25.
The urging force for urging toward 8 is set to a value higher than the waist strength of the sheet 1 and lower than the waist strength of the booklet 2. The sheet 1 is issued by printing the roll paper 18 and then cutting the roll paper 18 to a predetermined length.

In such a configuration, when the booklet 2 is inserted into the medium transport path 12 from above the table 23, and the state is detected by a medium insertion detecting sensor (not shown), the transport roller 13 is driven to rotate in the forward direction. Thereby, the booklet 2 is conveyed toward the print head 15, and desired information is printed by the print head 15 at a desired position of the booklet 2. When printing is completed, the transport roller 13 is driven to rotate in the reverse direction, so that the booklet 2 is returned to the table 23.

Since the state in which the booklet 2 remains on the table 23 is recognized by the detection signal of the medium detection sensor, if the state exceeds a certain period, it is determined that the booklet 2 has been forgotten by the customer. Then, the transport roller 13 is driven to rotate in the forward direction, and the collection rollers 26 and 27 are driven to rotate in the same direction as the transport roller 13. Thus, the booklet 2 is collected in the medium collection box 25.

When the sheet 1 is issued, the transport roller 19 is driven to transport the roll paper 18 toward the print head 21. The desired information is printed at a desired position on the roll paper 18 by the print head 21. The roll paper 18 on which printing has been completed is transported by the transport rollers 19, and is cut by the rotary cutter 22 into units of the sheet 1 having a predetermined length when transported by a predetermined distance. The cut sheet 1 is subsequently conveyed to the medium conveyance path 12 by the conveyance roller 19, and subsequently, the conveyance roller 1 is driven to rotate in the reverse direction.
By 3 the sheet is conveyed to the table 23.

Since the state where the sheet 1 remains on the table 23 is recognized by the detection signal of the medium detecting sensor, if the state exceeds a certain period, it is determined that the customer has forgotten to take the sheet 1. Then, the transport roller 13 is driven to rotate in the forward direction, and the collection rollers 26 and 27 are driven to rotate in the same direction as the transport roller 13. Thus, the sheet 1 is collected in the medium collection box 25.

Although the sheet 1 is formed by cutting the roll paper 18, the sheet 1 is warped, but in the present embodiment, the sheet 1 is warped in a direction in which the upper surface is concave.
It is collected in the medium collection box 25 with its concave surface facing up. This means that the inner surface of the roll paper 18 is pulled upward and the sheet 1 is transported without reversing its transport path.
This is due to the fact that

Here, the manner in which the sheet 1 and the booklet 2 are collected in the medium collection box 25 will be described. As shown in FIG. 2B, the sheet 1 has a curl so that the print surface faces upward and the print surface is curved in a direction in which the concave surface is formed. The medium is recovered by the medium recovery storage 25 so as to be warped upward, but is pressed by the medium pressing member 29. When the rear end of the sheet 1 is released from the collection rollers 26 and 27, the sheet 1 is warped upward but is pressed by the medium pressing member 29. This allows
The sheet 1 collected in the medium collection box 25 has its front and rear ends floating from the bottom surface 28, but its central portion is pressed by the medium press 29. As a result, even if the sheet 1 is warped, the position of the sheet 1 in the medium recovery storage 25 is kept constant. This is the same for the sheet 1 collected later.

Next, the state of collecting the booklet 2 is shown in FIG.
Shown in In this case, the torsion coil spring 30 pushes the medium holding member 29 with an urging force that is stronger than the stiffness of the sheet 1 and weaker than the stiffness of the booklet 2, and that
8, the medium pressing member 29 can be retracted upward when the booklet 2 is collected. Thereby, the booklet 2 with strong waist does not break.

Next, referring to FIG.
The case where the booklet 2 is collected in the medium collection box 25 in which is collected is described. In this case, the previously collected sheet 1 is pressed by the medium pressing member 29 and has a constant position and orientation as described above, and is located below the booklet 2 in the collection process. They will not be kicked or pushed by 2. When the rear end of the booklet 2 is released from the collection rollers 26 and 27, the booklet 2 drops by its own weight and presses the lower sheet 1. In this case, sheet 1
Even if the concave surface is warped with the concave surface facing upward, the position and the posture are kept constant, so that the booklet 2 does not bend and the warp can be corrected.

As shown in FIG. 2C, when the booklet 2 is lowered by its own weight, the medium pressing member 29 is rotated downward by the urging force of the torsion coil spring 30 to press the booklet 2 lightly. Therefore, when collecting the sheet 1 on the booklet 2, the position and the posture of the sheet 1 are kept constant by the medium press 29 as in the case described with reference to FIG. Can be.

Further, since the sheet 1 and the booklet 2 can be collected in the common medium collection box 25, the sheet 1 can be collected in an orderly manner while keeping the apparatus compact and simple.

As described above, the medium pressing member 29 that presses the sheet 1 from above, when the sheet 1 is the medium collection box 25 where the concave surface is collected upward, the leading end and the rear end of the sheet 1 are directed upward. Since it is warped, it works extremely effectively as warpage prevention.

However, the present invention is also effective in the case where the sheet 1 is warped with the concave surface facing down, and when the sheet 1 is collected in the medium collection storage 25 with the concave surface facing down. In this case, since the center of the sheet 1 in the medium collection box 25 is warped so as to bulge upward, the center of the sheet is pressed by the medium pressing member 29 so that the position and posture of the sheet 1 are kept constant and the sheet One can be overlaid.

The medium holding member may be displaced in a direction perpendicular to the bottom surface 28 of the medium recovery storage 25. As the urging means for urging the medium pressing member, a compression coil spring, a weight, or the like may be used. Alternatively, the medium holding member is formed of an elastically deformable spring material, and the medium collecting member 25 is provided with the spring pressure of the medium holding member.
May be used as a biasing means for the bottom surface 28 of the first embodiment.

[0032]

According to the first aspect of the present invention, there is provided a medium holding device for holding a sheet and a booklet with an urging force higher than the sheet's waist strength and weaker than the book's waist strength in a medium collecting box for collecting sheets and booklets. Since the member is provided, the sheet collected in the medium collection box is pressed by the medium holding member, and the floating and warping of the sheet from the bottom surface of the medium collection box can be suppressed. Even if the booklet is collected, it is possible to prevent the sheet below the booklet from being bent, and further, when the booklet is collected, the medium pressing member can be retracted upward, so that the lower back It is possible to prevent a strong booklet from breaking.

Since the printing device according to the second aspect includes the medium recovery device according to the first aspect, the same effect as that of the first aspect can be obtained.
