BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer having a function of printing on a cut sheet such as a printer such as a slip issuing machine, a copying machine, a facsimile machine, and more particularly to a printed cut sheet. The present invention relates to a printer device having a so-called vertical paper discharge structure in which paper is tilted backward almost vertically, discharged upward, and stands up in a paper discharge stocker to be stocked.

[0002]

2. Description of the Related Art FIG. 15 is a diagram schematically showing the construction of a conventional slip issuing machine. In FIG. 15, reference numeral 1 is a main body case, inside which a paper inlet opening at the front of the main body case 1 is provided. Two
A sheet conveyance path 2 having a is provided. The paper feed path 2 is provided with a plurality of pairs of paper feed rollers which are arranged at regular intervals and are in rolling contact with each other.

In FIG. 15, 3a and 3b are a pair of front and rear paper feed rollers 4a and 4b, which are disposed as discharge rollers at the end of the paper feed path 2 and are representative of other paper feed rollers. . These rollers 3a, 3b, 4a, 4b
Etc. are each provided with a plurality of rubber roller portions that are in rolling contact with the roller shaft. In addition, a pair of front and rear paper discharge rollers 3a, 3
One end of the rubber roller portion of b is separated from the rubber roller portion of the other side, and the small protrusions 5 are provided at this one end as shown in FIG. The small protrusions 5 are provided at regular intervals along the circumferential direction of the rubber roller portion, and
This enhances the conveyance power of the cut sheet 6.

A printing section including a platen 7 and a print head 8 is provided in the main body case 1 at a position midway along the paper transport path 2. The print head 8 is mounted on a head carrier 9 that is moved along the longitudinal direction of a platen 7 that extends in the width direction of the main body case 1.

On the upper rear side of the main body case 1, a paper discharge stocker 10 is arranged adjacent to the rear side of the transport end portion. The stocker 10 has a paper ejection support 10a which is provided to be tilted nearly vertically and projects rearward from the main body case 1, and the cut paper 6 printed on the support 10a is leaned against the paper ejection support 6a. It is designed to be tilted backward and tilted upright to be stocked.

Further, a cover 11 which covers the paper transport path 2 and the printing portion is detachably attached to the main body case 1, and the cover 11 is provided at the rear portion thereof and passes between a pair of front and rear discharge rollers 3a and 3b. It has an edge 11a facing directly above the front discharge roller 3a so as not to interfere with the upward discharge of the bill paper 6.

In the slip issuing machine, a single-cut sheet (slip) 6 inserted from the sheet inlet 2a is turned from a horizontal direction to a substantially vertical direction in the sheet conveying path 2 and conveyed, and after printing by a printing section. The printed single-cut sheet 6 is passed through a pair of front and rear discharge rollers 3a and 3b, is tilted almost vertically, and is discharged upward. Therefore, immediately after the lower end of the single-cut sheet 6 passes between the pair of front and rear discharge rollers 3a and 3b, the rear discharge roller 3b is rotated to move rearward along the upper peripheral surface of the roller 3b, that is, the discharge sheet 6 is discharged. The lower end of the cut sheet 6 is sent to the stocker 10 side. Cut sheet 6 printed and discharged in this way
The papers are leaned near the paper discharge support 10a vertically and leaned against each other, and are successively stocked in the paper discharge stocker 10.

As described above, this slip issuing machine can discharge the single-cut sheets 6 vertically to the discharge stocker 10, so that the discharge stocker 10 does not increase the installation space of the slip issuing machine. In addition, since most of the paper discharge stocker 10 is projected above the main body case 1, the main body case 1 does not hinder the removal of the stock sheets when the stocked cut sheets 6 are taken out. This is excellent in that it is possible to visually check the cut-out sheet that has been leaned against and to confirm the printing without being disturbed by the outer case 1.

[0009]

In the above structure,
When the cut-sheet paper 6 is stocked in the paper discharge stopper 10, if the cut-sheet paper 6 is short, the vertical discharge operation tends to be defective.

That is, the space between the discharge rollers 3a and 3b through which the cut-sheet paper 6 passes and the paper-discharge support 10a which leans the discharged cut-sheet paper 6 by leaning back a little so that it does not fall to the front side are separated from each other in the front-rear direction. Therefore, when the short cut sheet 6 is discharged, as shown by the dotted line in FIG.
3b and the sheet ejection support 10a, the short inclination angle of the cut sheet 6 (the straight line passing through the axis of both ejection rollers 3a and 3b and the sheet form 6 whose upper end is in contact with the ejection support 10a) The angle formed is small, and the short cut sheet 6 is largely tilted backward so that the lower end of the short cut sheet 6 projects forward. Along with that, Fig. 1
As indicated by the chain double-dashed line in FIG. 6, the lower end of the short cut sheet 6 is disengaged in front of the rear discharge roller 3b and easily rides on the front discharge roller 3a.

In this case, the short cut sheet 6 cannot receive the conveying force in the direction of the sheet discharging stocker 10 due to the rotation of the discharging roller 3b on the rear side, so that the sheet is discharged as indicated by the double-dashed line arrow in FIG. With the rotation of the roller 3a, the short cut sheet 6 is fed into the main body case 1 through the gap between the edge 11a of the cover 11 and the discharge roller 3a.
In particular, in a structure in which small projections 5 are provided not only on the rear side discharge roller 3b but also on the peripheral surface of the front side discharge roller 3a to enhance the conveying ability, a short cut sheet 6 can be transferred into the main body case 1. It is highly likely.

When a short cut sheet 6 enters the main body case 1 due to such a defective vertical sheet discharge operation, at that stage the paper issuance work such as a slip of the printer is temporarily suspended, and the cover 11 is opened and removed. It takes time to do the work. Moreover, in the printer device in which the print head 8 of the printing unit is moved by the head carriage 9, the short cut sheet 6 erroneously inserted into the main body case 1 is crushed and damaged by the movement of the head carriage 9. .

It is a first object of the present invention to obtain a printer device which is less likely to cause a defect in its vertical paper discharge operation regardless of the length of cut sheets. A second object of the present invention is, in addition to the first object, to provide a printer device having a simple structure and capable of surely performing a vertical paper discharge operation.

[0014]

In order to achieve the first object, a printer device of the present invention according to a first aspect of the present invention includes a main body case, and cut sheets vertically provided in the main body case. A paper conveyance path that tilts rearward near and ejects toward the outside of the main body case, and a printing unit that has a print head and a platen and that is disposed in the middle of the paper conveyance path, tilts backward nearly vertically. And a paper ejection stocker that is disposed adjacent to the rear end of the conveyance end of the paper conveyance path and has a paper ejection support projecting above the main body case. And a paper discharge transfer means that is provided above the section and applies a transfer force to the discharged paper stocker side to the discharged single-cut sheets.

In order to achieve the second object, in the printer device of the present invention according to claim 2, the paper discharge transfer means is arranged above the terminal end portion so as to face the transfer terminal end portion. In addition, a support base having a supporting portion located on the front side of the cut sheet discharged from the transport end portion and a paper discharge pressing portion intersecting with the cut sheet discharged from the transport end portion are formed. It has one side and the other side bent from it, and is made of a flexible and deformable material, and
A pressing plate provided by fixing the other side to the support portion,
The reinforcing plate is harder than the discharge pressing portion and has a corner supporting portion that is in close contact with an outer surface of a corner formed by two sides of the pressing plate and is fixed to the supporting portion.

Further, in order to achieve the first object,
A printer device according to a third aspect of the present invention includes a main body case, and a pair of front and rear discharge rollers that are provided in the main body case and are rotatably driven so as to be in rolling contact with each other at the conveyance end portion.
A sheet conveyance path for inclining the single-cut sheet nearly vertically through the ejection rollers and ejecting it toward the outside of the main body case, and a print head and a platen are provided in the middle of the sheet conveyance path. A print unit, and a paper discharge stocker disposed adjacent to the rear side of the transport terminal end unit, having a paper discharge support that is tilted nearly vertically and protrudes above the main body case, Among the pair of discharge rollers, a roller having no small protrusions protruding from its peripheral surface is used as the discharge roller arranged on the front side, and a large number of protrusion rollers protruding from the peripheral surface are arranged on the discharge roller arranged on the rear side. It is characterized by using a roller having small protrusions.

[0017]

In the configuration of the invention according to claim 1, the printing unit prints on the cut sheet conveyed through the sheet conveying path, the sheet conveying path conveys the cut sheet, and the printing is performed from the conveying end portion. Dispose of the cut sheets that have already been used by tilting them backward to the outside of the main unit case vertically and discharging them upward. In the paper output stocker, the ejected paper sheets are placed in a state in which the ejected paper sheets rest on the paper ejection support and are tilted nearly vertically so as not to fall forward.
Further, the discharged sheet transfer means applies a transfer force to the discharged sheet stocker side to the cut sheet discharged from the transport end portion, and forcibly transfers the cut sheet to the rear side.

Therefore, when the printed single-cut sheet is discharged from the conveying end portion of the sheet conveying path, the lower end portion of the sheet is forcibly received by the sheet discharging transfer means to the rear side of the sheet discharging stocker side. Since it is transferred to the case, it is possible to prevent the ejected cut sheet from accidentally entering the main body case, not only when the ejected cut sheet is long, but also when the cut sheet is short. It can be reliably transferred to the paper discharge stocker and can be stocked by standing almost vertically.

In the structure of the invention according to claim 2,
The support portion of the support base is used as a mounting portion for the pressing plate and the reinforcing plate, and the corner supporting portion of the reinforcing plate is in close contact with the outer surface of the corner portion formed by the two sides of the pressing plate to support the corner portion from below. As a result, fatigue at the corner portions due to repeated flexible deformation of the sheet discharge pressing portion is reduced.

According to the second aspect of the invention, the cut sheet discharged from the conveying end portion of the sheet conveying path is discharged while flexibly deforming the sheet discharge pressing portion located in the discharging direction. The elastic force of the paper pressing portion returning to the original state pushes the paper pressing portion toward the paper discharge stocker. Therefore, the lower end of the ejected cut sheet is forcibly transferred to the ejected paper stocker side by the pressing action of the ejected paper pressing portion that is in contact with the ejected cut sheet. However, even if it is short, the ejected cut sheets can be prevented from accidentally entering the main body case, and the cut sheets can be reliably transferred into the paper output stocker and can be vertically stood up and stocked. .

Moreover, the sheet discharging and transporting means of the invention according to the second aspect of the invention forces the sheet to be cut by the elastic force generated by being flexibly deformed in the sheet to be discharged as described above. Since it has a mechanical structure that transfers it to the paper output stocker side,
The structure is simple and the operation is highly reliable.

Further, in the structure of the invention according to claim 3, the pair of front and rear discharge rollers provided at the transport end portion of the paper transport path give a final transport force to the printed single-cut sheet, The paper is tilted nearly vertically and discharged upward. Of these rollers, only the rear discharge roller has a large number of small protrusions on its peripheral surface,
The conveyance force of the rear discharge roller for single-cut sheets is larger than that of the front discharge roller having no such small protrusions.

Therefore, for example, a short cut sheet is
When attempting to fall so that the lower end thereof approaches the front side, the behavior is hindered by a catch with the small protrusion. Moreover, even if the short cut sheet falls down so that the lower end of the short cut sheet pushes forward and the lower end of the short cut sheet tries to ride on the front discharge roller, at that stage, the short cut sheet does not reach the lower end of the short cut sheet. Since the front and rear discharge rollers are in contact with each other, it is possible to prevent the lower end portion of the cut sheet from completely riding on the front discharge roller due to the difference in the transporting force.

Therefore, according to the third aspect of the invention, the lower end of the cut sheet is forcibly discharged through the engagement between the lower end of the discharged sheet and the small protrusion of the rear discharge roller. Since it is transported to the paper stocker side, it is possible to prevent the discharged single-cut sheets from accidentally entering the main body case, not to mention the case where the discharged single-cut sheets are long The paper can be reliably transferred into the paper output stocker and can be stood upright and stocked.

Has been done. By this attachment, the corner portion covers a part of the tip of the cutter portion 77, and the paper discharge pressing portion 80a is arranged so as to intersect with the slip discharged from the transport end portion. The arrow indicated by the chain double-dashed line in FIG. 4 is the slip discharge path in the case where the pressing plate 80 is not provided, and the paper discharge pressing portion 80a is provided so as to intersect the path at a substantially right angle. ing.

The reinforcing plate 81 is made of a synthetic resin material that is thicker (for example, 0.125 mm) than the pressing plate 80 and is hard, and is in close contact with the outer surface of the corner portion 80d formed by the two sides 80a and 80b of the pressing plate 80. It has a corner support portion 81a at the lower end. The reinforcing plate 81 is the other side 8 of the pressing plate 80.
It is provided by heat welding to 0b. The corner support 8
1a is only in close contact with the corner portion 80d of the pressing plate 80, and heat welding is not performed in this portion. The corner support portion 81a supports the sheet discharge pressing portion 80a from below so that the angle θ (see FIG. 4) formed by the sheet discharge pressing portion 80a and the other side 80b in the unloaded state does not become larger than an obtuse angle that is close to a right angle. ing. In particular, in this embodiment, in order to improve the transfer performance of the discharged slips to the paper discharge stocker 61 side, the paper discharge pressing portion 80a is set at an angle of not more than 90 degrees, especially about 90 °. I am trying to hold it.

As shown in FIG. 12, the three pressing members 79 are respectively attached at positions corresponding to slips of various sizes to be inserted with the left side sheet insertion guide 28 as a reference. In FIG. 12, the first-type slip indicated by reference character L has a business card size with a width of about 50 mm, the second-type slip indicated by N has a width of about 120 mm, and the third-type slip indicated by M has a width of about 12 mm.
It is a large size exceeding 0 mm. The first pressing body 79 disposed on the leftmost side is provided so as to be able to contact each of the first to third type slips L, N, and M, and the first pressing body 79 disposed on the rightmost side. The third pressing body 79 is provided so as to be able to contact only the third type slip M, and the second pressing body 79 disposed in the middle of these is the second type and third type slip N, It is provided so as to be able to contact M.
In the case of the above left reference, the right side sheet insertion guide 29 is slid in the arrow direction of the center 12 according to the size of the slip used.

In the slip issuing machine having the above-mentioned structure, the slip inserted into the paper insertion port 27 and sandwiched between the first paper feed rollers 33 and 44 of the paper conveyance path B is conveyed along the paper conveyance path B, Printing is performed by the printing operation of the print head 51 mounted on the head carriage 49 that moves in the longitudinal direction of the platen 37 as the carriage drive motor 50 rotates forward or backward when passing through the printing unit. Then, the post-slip that has passed through the printing section is passed between them by a pair of front and rear discharge rollers 36 and 47 positioned at the transporting end portion of the sheet transporting path B, and is tilted nearly vertically to the main body case 2
1 is discharged upward.

The slips discharged in this vertical discharge are
The paper is transported to the rear, that is, the paper stocker 61 side by the paper discharge transfer means provided near the upper end of the transport end portion so as to face it.

That is, the slip discharged from the end of the sheet conveyance path B is pressed by the pressing plate 8 located in the discharging direction.
Since the 0 sheet discharge pressing portion 80a is discharged while being pushed up and deformed flexibly as shown in FIG. 5 or 6, the sheet discharge pressing portion 80a receives an elastic force to return to the original state. The sheet is pushed toward the paper output stocker 61. Such a backward biasing action on the discharged slip continues for the duration of the discharge of the slip. It should be noted that FIG. 5 shows the degree of flexible deformation of the paper discharge pressing portion 80a with respect to a slip having a short length, and FIG. 6 similarly discharges a slip having a long length. If this happens, the paper discharge pressing unit 8 for this slip
The degree of flexible deformation of 0a is shown.

Therefore, as soon as the lower end of the discharged slip comes out of the space between the discharge rollers 34 and 47, the discharged slip is forcibly forced by the paper discharge stocker 61 side to be restored by the pressing action of the paper discharge pressing portion 80a. Be transferred to. As a result, even in the case of a short slip discharged between the discharge rollers 34 and 47 and the paper discharge support 63 of the paper discharge stocker 61 with a relatively large inclination, the lower end of the short slip comes off the space between the discharge rollers 34 and 47. Further, the sheet is prevented from riding on only the discharge roller 47 on the front side, and is forcibly transferred to the discharge stocker 61 side.

Therefore, irrespective of the length of the discharged slip, the discharged slip can be prevented from accidentally passing between the cutter portion 77 and the discharge roller 47 and entering the main body case 21. This ensures that the slips are ejected from the stocker 61
The paper can be transported inside, the lower end thereof can be supported by the bottom wall 62a, and the paper ejection support 63 can be leaned against the paper ejected bills to be vertically held in the paper ejection stocker 61.

As described above, the pressing plate 80 of the sheet discharge pressing means is set to correspond to the size of various slips to be inserted while the left side sheet insertion guide 28 is used as a reference and the sheet is guided along the sheet.
In the vertical discharge operation, since the first type slip L having the smallest business card size is flexibly deformed, the discharge pressing portion 80a of one pressing plate 80 is moved to the discharge stocker 61 side in the vertical discharging operation. A second that gives a transfer force and is larger than a business card size
With respect to the seed slip N, the discharge pressing portion 80 of the two pressing plates 80
The flexible deformation of a gives a transfer force to the paper discharge stocker 61 side, and for the third type slip M larger than the size of the second type slip N, the discharge pressing portions 80a of the three pressing plates 80 are provided. Due to the flexible deformation, a transfer force to the paper ejection stocker 61 side is given.
Therefore, a transfer force to the discharged stocker 61 side can be applied to the discharged slip at an appropriate position in the width direction, and the discharged slip is discharged obliquely due to the resistance of the discharge pressing portion 80a. Can be prevented.

Since only the rear discharge roller 47 of the pair of front and rear discharge rollers 34, 47 on the sheet conveying path B has a large number of small projections 40 on its peripheral surface, such small projections are provided. The conveyance force of the rear discharge roller 34 with respect to the slip in the front-rear direction is larger than that of the front discharge roller 47 having no sheet.

Therefore, for example, when a slip having a short length tries to fall down so that the lower end of the slip slips forward, its behavior can be hindered by the small projection 40. Moreover, even if a short voucher falls down so that the lower end of the voucher is pushed forward and the lower end tries to ride on the front discharge roller 34, both front and rear ejections are performed at the lower end of the short voucher at that stage. Since the rollers 34 and 47 are in contact with each other, it is possible to prevent the lower end of the slip from completely riding on the front discharge roller 47 due to the difference in the conveying force.

Therefore, the discharged slip can be forcibly transferred to the paper discharge stocker 61 side through the engagement between the lower end of the slip and the small protrusion 40 of the rear discharge roller 34. Even with only such a transfer action, regardless of the length of the discharged slip, the discharged slip is prevented from accidentally entering the main body case, and the slip is reliably transferred into the paper discharge stocker 61. It can be stocked by standing vertically.

In this embodiment, as described above,
Since the sheet pressing portion 80a is flexibly deformed to transfer the main body case 21 to the rear side and the engagement with the small protrusions 40 to transfer the main body case 21 to the rear side, the discharged slip is discharged. The certainty of transferring the paper into the paper stocker 61 is extremely high.

Note that, as described above, the vertical discharge operation of the slip rarely occurs. Therefore, in order to remove the slip that has entered the main body case 21, the work of issuing the slip is temporarily suspended and the cover 30 is closed. It is possible to reduce the inconvenience that the discharged slips enter the main body case 21 and are crushed and damaged by the movement of the head carriage 9 while the opening and removing work are rarely performed.

The corner supporting portion 81a of the reinforcing plate 81 in the sheet discharging and transferring means is in close contact with the outer surface of the corner 80d formed by the two sides 80a and 80b of the pressing plate 80, and supports the corner 80d from below. As a result, fatigue at the corners due to repeated flexible deformation of the discharge pressing portion 80a is reduced. for that reason,
Even when it is used for a long period of time, the discharge pressing portion 80a does not hang down, and the desired slip transfer action can be maintained. In addition, the paper discharge transfer means is a mechanical device for forcibly transferring the slip to the paper discharge stocker 61 side by the elastic force generated by being flexibly deformed using the slip discharged as described above. Since it is a structure, its structure is simple and its operation is highly reliable.

The same effect as this is obtained by ejecting the main body case 21 and the slip (cut sheet) provided in the main body case 21 so that the slip (cut sheet) is tilted almost vertically to the outside of the main body case 21. The paper transport path B, the print section having the print head 51 and the platen 37, which is disposed in the middle of the paper transport path B, and is tilted almost vertically and protrudes above the main body case 21. A paper ejection stocker 61 having a paper ejection support 63 and disposed adjacent to the rear end of the conveyance end portion of the paper conveyance path B, and is flexible and deformable and ejected from the conveyance end portion. The slip that has a paper discharge pressing portion 80a that intersects with the slip (single-cut paper), is provided above the terminal end portion facing the conveyance end portion, and is discharged by the paper discharge pressing portion 80a. Contact this (single-cut sheet) and place this slip on the paper output stocker 61 side. (Consisting of the support base 71 and the pressing member 79.) Pressed to the paper discharge pressing means and can be obtained even in the printer apparatus, such as a slip issuing device provided with the.

In the slip issuing machine (printer device) of the one embodiment, the main body case 21 and the main body case are provided in the main body case 21 so that the slip (cut sheet) is tilted almost vertically to the rear. 21. A sheet conveying path B that discharges upward and outward, a printing unit that has a print head 51 and a platen 37 and is arranged in the middle of the sheet conveying path B, and the main body is tilted backward almost vertically. A paper discharge stocker 61, which has a paper discharge support 63 protruding above the case 21 and is arranged adjacent to the rear end of the conveyance end of the paper conveyance path B, is flexible and deformable. A paper discharge pressing portion 80a intersecting with the slip (single-cut sheet) discharged from the conveying end portion is provided above the terminal end portion so as to face the conveying end portion. This voucher for the voucher (single-cut sheet) discharged in 80a The sheet discharge presser (comprising the support base 71 and the pressing body 79) for pressing the sheet discharge stocker 61 is provided, and the intersecting angle θ between the sheet discharge direction and the sheet discharge pressing portion 80a. It has a configuration with an acute angle.

Therefore, it is possible to reduce the possibility that the print quality is deteriorated due to the paper discharge pressing means and the risk that the discharged slip is mistakenly introduced into the main body case 21.

That is, if the intersecting angle θ is a large obtuse angle, the discharge resistance when the slip discharged from the discharge pressing portion 80a inclined rearward becomes excessive, and therefore the discharge is discharged. The leading edge of the slip is the paper ejection pressing portion 80.
It is pressed by a, and the discharged portion of the slip between the discharge pressing portion 80a and the discharge rollers 34 and 47 is curved so as to cause buckling, which adversely affects printing such as disturbance of the print pitch. May cause In addition, when the condition that the discharge pressing unit 80a is too stiff is applied, the discharged slip is transferred to the front side by using the lower surface of the discharge pressing unit 80a inclined rearward and downward as a guide, and the main body case 21 may get inside.

However, in the present embodiment, since the intersection angle θ is an acute angle, the discharge resistance of the discharge pressing portion 80a with respect to the discharged slip becomes appropriate, and
Since the function of guiding the discharged slips by the paper discharge pressing portion 80a into the main body case 21 does not occur, the intended purpose of the present invention is not brought about without lowering the printing quality or introducing the slip into the main body case 21 by mistake. The purpose of can be achieved by the above-mentioned effects.

Further, the voucher issuing machine (printer device) of the one embodiment can select and print a voucher (single-cut sheet) and continuous paper E and continuously cut out the printed portion of the continuous paper. A printer device including a paper cutter includes a main body case 21, and a pair of front and rear discharge rollers 34 and 47 which are provided in the main body case 21 and are rotationally driven to rotate at the transport end portion. A paper conveyance path B through which the slips (single-cut sheets) are tilted nearly vertically through the rollers 34 and 47 and discharged toward the outside of the main body case 21, the print head 51, and the platen 37.
And a paper discharge support 63 that is disposed in the middle of the paper transport path B and has a paper ejection support 63 that is tilted nearly vertically and protrudes above the main body case 21. (Voting paper)
And a sheet discharge pressing means (comprising a support base 71 and a pressing body 79) for pressing the sheet discharge stocker 61 to the sheet discharge stocker 61 side. Support provided with a cutter portion 77 arranged above and positioned on the front side of the voucher (single-cut sheet) discharged from the transport terminal end portion, protruding downward, and capable of coming into contact with and separating from the rear discharge roller 34. A flexible and deformable material having a base 71, one side forming a sheet discharge pressing portion 80a intersecting with the slip (single-cut sheet) discharged from the transport end portion, and the other side 80b bent from this. And a pressing plate 80 that is formed by fixing the other side 80b to the cutter part 77 and is harder than the paper discharge pressing part 80a, and two sides 80a and 80b of the pressing plate 80 are Outside the corner 80d And a configuration in which characterized in that a corner support portion 81a which is closely made reinforcing plate 81 fixed to the cutter portion 77, also serving as the continuous paper cutter by the support base 71 in.

In this structure, the above-mentioned operation can achieve the intended object of the present invention, and since the support base also serves as the continuous paper cutter, it is necessary to prepare a special part for the support base. Therefore, the number of parts is small, and the structure and assembly can be simplified.

The present invention is not limited to the above embodiment. For example, the support base may be provided integrally with or separately from the main body case 21 or the cover 30 without also serving as a continuous paper cutter.

Further, the paper discharge transfer means is not limited to the one embodiment. For example, the operation is performed at the timing when the paper is completely discharged, and the paper is reciprocated in the front-rear direction by using a plunge type solenoid arranged above the discharge rollers 34 and 47 and in front of the paper discharge stocker 61. Alternatively, the lower end of the sheet discharged by the plunger may be pushed backward to be transferred to the sheet discharge stocker 61 side. Alternatively, the air horn is communicated with the air horn via the air supply pipe and is above the discharge rollers 34 and 47, and is in the discharge stocker 61.
And an air nozzle disposed on the front side of the sheet, the lower end portion of the sheet ejected in a non-contact manner by blowing air backward from the air nozzle at the timing when the ejection of the sheet is completed or continuously. Push backward to eject the paper stocker 6
You may make it transfer to the 1 side.

Since the present invention is constructed as described above in detail, it has the following effects.

According to the first aspect of the invention, the lower end portion of the cut-sheet paper which is printed and discharged from the conveyance end portion of the paper conveyance path is forcibly moved to the paper discharge stocker side by the paper discharge transfer means. , Regardless of the length of the cut sheet, the discharged cut sheet can be prevented from accidentally entering the main body case, and the cut sheet can be reliably transferred into the discharge stocker and set up almost vertically. There are few defects in the vertical paper ejection operation for stocking.

According to the second aspect of the invention, the lower end portion of the cut-sheet paper which is printed and discharged from the transport end portion of the paper transport path is forcibly transferred to the paper discharge stocker side by the paper discharge transfer means. , Regardless of the length of the cut sheet, the discharged cut sheet can be prevented from accidentally entering the main body case, and the cut sheet can be reliably transferred into the discharge stocker and set up almost vertically. There are few defects in the vertical paper ejection operation for stocking. In addition, the ejected sheet transfer means causes the elastic force generated by flexibly deforming the ejected sheet pressing portion of the pressing plate by the ejected cut sheet sheet to act on the cut sheet sheet, and the lower end portion of the cut sheet sheet is operated. Since it has a mechanical structure for forcibly transferring to the paper discharge stocker side, the structure is simple and the vertical paper discharge operation can be performed with high reliability.

According to the third aspect of the invention, a large number of small protrusions are provided on the peripheral surface of the rear discharge roller of the pair of front and rear discharge rollers included in the sheet conveying path, and the front side having no such small protrusions.
