Description

[Detailed description of the invention] The present invention relates to a stamping device.

Documents that require a seal, such as various certificates, contracts, and certified copies and extracts of real estate and commercial documents, are often stamped manually. Generally, there are not many opportunities to stamp this type of document, so
Manual work is often sufficient and can be done in time, but for government offices,
In offices that handle document preparation, a decline in work efficiency due to manual work often deteriorates the quality of the work.

For this reason, automatic stamping devices have been proposed that automatically stamp the official seal of the mayor of the city, ward, town, or village, issue number, issue date, etc., and are used for issuing office work such as seal registration certificates and various certification letters. The aim is to improve administrative efficiency.

However, this conventional stamping device has a structure in which a sheet to be stamped (certificate, etc.) is passed between a stamping roller on which a stamping board is arranged and a pad roller that rotates in pressure contact with the stamping roller. In order to synchronize the loading timing of the stamping roller with the sheet relative to the stamping plate, a synchronization mechanism is required, and a spacer roller for separating the stamping roller and pad roller is used to transport only the sheet when the stamping roller is stopped. A mechanism for idling is required for conveyance, and the mechanism around the stamping roller tends to become complicated. Furthermore, although the above-mentioned pad roller is separated from the circumferential surface of the stamping roller by the above-mentioned spacer roller, since this pad roller needs to be in pressure contact with the stamping plate, the sheet may be held in place by a sheet jam or the like. If the stamping roller and the pad roller come into contact before reaching this point, there is a risk that the ink from the stamp plate will adhere to the pad roller, causing stains on the back of the sheet.

Furthermore, in the event that a sheet jam should occur between the stamping roller and the padded roller, since they are in pressure contact with each other, there is a risk of accidentally damaging important official seals, etc. when removing the jammed sheet.

In view of the above-mentioned points, an object of the present invention is to provide a complicated timing synchronization mechanism between the stamping roller and the sheet,
To provide a stamping device which does not require an idling mechanism of a spacer roller, and which causes extremely little staining on the back of sheets and occurrence of sheet jams.

The present invention will be explained below with reference to an illustrated embodiment.

The stamping device according to the present invention can be put to practical use, for example, as a stamping device in a bookbinding machine that automatically binds multiple sheets, such as certified copies and extracts, or general printed matter and copies, into a part or a single document or booklet. be converted into

FIG. 1 is an external view of an example of the above-mentioned bookbinding machine.

This bookbinding machine is equipped with a folding device, a signing device, and a stamping device for folding, signing, and stamping sheets, and by using this bookbinding machine in combination with a copying machine, it is possible to make certified copies and extracts. Copying and binding can be performed automatically.

1 and 2, reference numeral X indicates a copying machine, Y indicates a bookbinding machine, 100 indicates a folding device, 200 indicates a stamping device, and 300 indicates a stamping device, respectively.

Hereinafter, taking the case of creating a certified copy (or an extract) as an example, the production process will be described step by step, and the structure, operation, and function of the bookbinding machine Y will be mainly explained.

First, the original copy is copied by copying machine X.

The original certified copy is shown in Figures 1 and 2.
Document feeding device 40 arranged on the top plate of copying machine X
0, the document is guided to an image scanning section (not shown) of the copying machine X, the information on the original document is scanned, and then the document is discharged onto the document discharge tray 401. The information on the original document is scanned by the above-mentioned scanning unit and transferred to the information recording medium (photosensitive drum and its peripheral devices) 402.
The data is copied onto a copy sheet (hereinafter simply referred to as a sheet) S via the . The sheet S on which the original information has been copied is delivered to the sheet discharge port 4 formed in the copying machine
03, and is transported toward the bookbinding machine Y.

The sheet S discharged from the sheet discharge port 403 is placed on the side of the bookbinding machine Y facing the copying machine X at a location opposite to the sheet discharge port 403.
Sheet introduction port 5 for introducing the into the bookbinding machine Y
01 is formed.

As shown in FIG. 3, the sheet S discharged from the sheet discharge port 403 of the copying machine The sheet is conveyed through the sheet to a sheet carry-in roller 502 disposed on the side of the bookbinding machine Y.

The sheet S carried into the bookbinding machine Y is conveyed by a carry-in roller 502, and as shown in FIG. , proceed toward the first conveyance roller 504. Note that the carry-in roller 502 and the first conveyance roller 504 are
Through the through holes 503a and 503b drilled in the first sink plate 503, a portion of each peripheral surface is
Steel balls 502a and 504a are exposed on the upper surface of the first sink plate 503, and steel balls 502a and 504a are provided on each exposed peripheral surface.
These steel balls are brought into contact with each other by their own weight, and the sheet is held and conveyed by each steel ball and each roller. ). A feature of this conveyance roller having a ball roller structure is that the sheet conveyed by the ball roller can be easily moved in the direction in which the sheet is conveyed by the conveyance roller.

By the way, by the carry-in roller 502, the first
The rear end (the left end in FIG. 4) of the sheet S conveyed on the sink plate 503 touches the carry-in roller 50.
Immediately before it leaves the paper 2, its tip is conveyed by the first conveyance roller 504 and further advances.

The sheet S further conveyed on the first flow plate 503 by the first conveyance roller 504 is arranged in a direction substantially perpendicular to the carry-in path A.
On the partition plate 506 located approximately in the center of the bookbinding machine body,
Due to the contact of the leading end thereof, the advance of the sheet S is temporarily stopped on the first flow plate 503 (this stopping position of the sheet S will be hereinafter referred to as the first position of the sheet).

In addition, the sheet introduction port 501 and the carry-in roller 50
In the middle part between 2 and 2, as shown in Figure 3, there are
A movable guide plate 507 is arranged along the first sink plate 503. This movable guide plate 507 moves the next sheet carried in from the copying machine to the bookbinding machine when the sheet S carried by the carry-in roller 502 does not reach its first position even after a predetermined time has passed. It functions to expel water to the outside. Whether or not the sheet S has reached the first position is determined by a first sensor SW 1 that detects the presence or absence of a sheet placed near the carry-in roller 502 across the sheet carry-in path, and by a first sensor SW ₁ of the first conveyance roller 504. Nearby,
It is detected by a second sensor SW ₂ which is arranged in substantially the same way as the first sensor SW ₁ .

In other words, the sheet S traveling along the sheet carry-in path
is detected by the first sensor SW ₁ , and after a predetermined time (by a timer) has elapsed, the second sensor SW 1 detects the tip of the
If it is not detected by the sensor SW ₂ , as shown in FIG. 3, the plunger 508 is excited, the movable guide plate 507 rotates to the left about its support shaft 507a, tilts to the position shown by the chain line 507A, and the copying machine The next sheet brought in from X is discharged above the binding machine. This prevents continuous sheet jamming.

Note that the operation of the movable guide plate 507, that is,
As the plunger 508 is energized, a copying command from the copying machine
The operation of the sheet conveyance system stops. As described above, when the occurrence of sheet jam on the first sink plate 503 is detected, the top plate 509 of the bookbinding machine Y (see Fig. 1), which is configured to be openable and closable with respect to the main body of the bookbinding machine, is opened. It is opened to expose the conveyance path of the sheet S, and the jammed sheet is removed.

When each of the first and second sensors described above detects the sheet S within the predetermined time, the sheet S is placed in the direction along the partition plate 506, which is substantially orthogonal to the sheet carrying path A. 1 Through conveyance route B,
It is conveyed on the first sink plate 503. A folding device 10 is provided downstream of this first conveyance path B (see FIG. 2).
0 sheet introduction part 100a corresponds to the 5th sheet introduction part 100a.
(see figure).

The sheet S is conveyed to the folding device 100 by selectively moving steel balls toward and away from the circumferential surface of a rotating roller.
This is carried out by a conveying roller (hereinafter referred to as a ball solenoid roller) that conveys the sheet by sandwiching the sheet between the roller and the steel balls.

The above-described first ball solenoid roller 510 is disposed at a corner of the first sink plate 503 near the partition plate 506 and the folding device 100.

This first ball solenoid roller 510 is
When the sheet S reaches the first position on the first flow plate 503 and is not detected by the second sensor SW ₂ , the sheet conveying function is in a state of being cancelled. Therefore, sheet S is the second sensor.
When detected by SW ₂ , the first ball solenoid roller 510 functions to advance the sheet S along the first conveyance path B and feed it into the folding device 100 . After the sheet S is folded in half by the folding device 100, the sheet S is placed on a second flow plate 511 by a second conveying roller 51 having a ball roller structure.
2.

The second sink plate 511 is located below the first sink plate 503 and closer to the folding device 100.
03, and its folding device 1
The end closer to 00 corresponds to the sheet discharge section 100b of the folding device 100 (see FIG. 5). The sheet S conveyed onto the second flow plate 511 has its side edge (right side in FIG. 5) along the second conveyance path C of the sheet from the folding device 100 to the second flow plate 511. (See Fig. 1) The sheet S is temporarily stopped by contacting the sheet stopper 513 arranged in a direction substantially perpendicular to the sheet S (see Fig. 1). position). In this second position, the sheet S is
Its direction of travel is changed by approximately 90 degrees. That is,
At the same time as the sheet S reaches the second position, the third conveyance roller 513 with a ball roller structure is mounted on another spindle that rotates substantially perpendicular to the spindle of the second conveyance roller 512. After being conveyed, it is conveyed along a third conveyance path D that is substantially orthogonal to the second conveyance path C (see FIG. 6). The sheet S whose sheet conveyance direction has been changed in the above-mentioned second position is transferred to a sheet sealing section provided adjacent to the second sink plate 511 on the side of the second position (right side in FIG. 2). You will be directed to 514. The sheet S conveyed to the sheet stamping section 514 is temporarily stocked on the sheet laminate plate 515.

The sheet laminated plate 515 has its sheet stacked surface located at a lower position than the sheet guide surface of the second flow plate 511 by a height corresponding to the maximum stacked amount of sheets stored on the sheet laminated plate 515. It is arranged like this.

Also, the sheet feeding side of the second sink plate 511 of this sheet sealing part 514 (right side in FIG. 6)
The leading edge Sa of the sheet S carried into the sheet sealing section 514 is placed in the sheet carrying-in section 514a corresponding to
The sheet is bent toward the sheet stacking surface and the height of the upper surface of the sheet stacked on the sheet stacking plate 515 is lower than the height of the sheet guide surface of the second flow plate 511. , and a sheet guide member 516 are provided. This sheet guide member 516 serves as the tip of the sheet S when the sheet S is carried from above the second flow plate 511 toward the sheet laminate plate 515 by the fourth conveyance roller 517 having a ball roller structure. Sa is the rear end Sb of another sheet previously stocked on the laminate 515 (see FIG. 7) or the sheet sealing part 514.
This serves to prevent the sheet S from colliding with the stamping device 200 (see FIG. 8) disposed in the sheet stamping section 514 and preventing the sheet S from being carried into the sheet stamping section 514. That is, if the leading edge Sa of the sheet S carried into the sheet sealing section 514 is curled or folded,
If this sheet S is carried into the sheet sealing section 514 from above the second flow plate 511 as it is (without the sheet guide member 516), the leading edge Sa of the sheet may be curled or folded.
Alternatively, as the sheet advances, the sheet S is guided upward from a predetermined path due to buoyancy acting on it, and collides with the upwardly extending portion of the sheet laminate plate 515 of the sealing device 200. Therefore, there is a risk that its progress will be blocked.

Furthermore, even if the sheet itself does not have any curls, the sheet stacked on the sheet laminate 515 is folded in half by the folding device 100, so the bulge at the fold However, even when the same number of identical sheets are stacked, it is predicted that the height of the stacked sheets will change due to changes in humidity during use and subtle changes in the degree of creases, and the height of the stacked sheets will not be constant. be done.
Therefore, when the height of the stacked sheets becomes higher than the height of the sheet guide surface of the second flow plate 511 due to the expansion, the leading edge of the next sheet is already stacked. This causes a problem in that the rear end of the seat collides with the rear end of the seat and its progress is blocked.

Therefore, the sheet guide member 516 described above
, the sheet loading section 514a of the sheet sealing section 514
By disposing the sheet S into the sheet sealing section 514 from above the second flow plate 511,
All of the above-mentioned problems are solved because all the sheets are delivered or stacked at a height lower than the predetermined height, regardless of the presence or absence of curls or creases or the degree of bulge in the folds.

Note that a third sensor SW ₃ is disposed near the fourth conveyance roller 517 to detect the presence or absence of a sheet in the same manner as the sensors described above.

The third sensor SW ₃ is a sensor for detecting whether or not a sheet jam occurs while the sheet S is being conveyed from the first conveyance path B to the second conveyance path C. After the tip of S is detected by the second sensor SW ₂ ,
When the time required to be detected by the third sensor SW ₃ exceeds a predetermined time (preset by a timer) during normal transportation, the process is performed between the first and second sensors. In the same manner as above, the sheet jam is detected and the movable guide plate 507 is activated (see FIG. 3).

By the way, as described above, the sheet is placed on top of the sheet S carried into the sheet sealing section 514 without causing a sheet jam, in the same position as it was, that is, in the state in which it was carried in.
When the next sheet is stacked on top of it, the sheets are likely to be misaligned with each other. Therefore, if sheets in an irregular state are signed as they are with the signing device 200, not only will the quality of the certified copies be poor, but there is also a risk of sheet jamming during the process of transporting the sheets to the next process. There is.
Therefore, it is necessary to align the stacked sheets with each other in the sheet marking section 514.

This alignment of the sheets is performed on the third conveyance path D described above.
A first aligning device 600 for aligning the side edges Sa of the leading edge of sheets traveling along a fourth conveying path E (see FIG. 1) that is substantially orthogonal to the third conveying path D. A second aligning device 700 for aligning the other side edges Sc of the advancing sheets (see FIG. 9)
It is done by.

The first alignment roller 601 is disposed above the sheet laminate plate 515, and is rotated in a direction that causes the sheet S to advance along the third conveyance path. The first contact/separation member 602 is made of an elastic body such as a leaf spring, and the base 602a is connected to the first contact/separation member 602.
It is pivotally connected by a support shaft 606 to a bracket 605 fixed to the outside (right side in FIG. 8) of a side plate 603A that also serves as a seat stopper 603. The free end 602b of the first contacting/separating member 602 passes through the through hole 603a of the side plate, sandwiches the sheet laminate 515, and extends below the first alignment roller 601. The first sheet stopper 603 is located at a position away from the side edge Sa of the carrying side of the sheet S carried on the upper surface of the sheet stacking section 515, in a direction substantially orthogonal to the third conveyance path D; That is, the partition plate 5

In addition, the second sheet stopper 703 is in a position where its swinging is prevented, and the sheet laminate plate 515
The extending end 703a of the sheet S is placed at a distance from the other side edge Sc of the sheet S carried in above.
is coming.

Sheet S carried onto sheet laminate plate 515
are aligned in the following manner by each alignment device 600 and 700 configured as described above.

That is, the rear end Sb of the sheet S carried onto the sheet laminate 515 along the third conveyance path D
When the sheet passes through the third sensor SW ₃ , the sheet rear end detection operation of the third sensor SW ₃ serves as a trigger, and the first plunger 604 is excited. Note that at the time when the rear end of the sheet S passes the third sensor, its leading edge Sa and side edges Sc are aligned with the first alignment roller 601 and the second alignment roller 601.
They are located below the alignment rollers 701, respectively.
When the first plunger 604 is excited, the first contact/separation member 602 swings around the support shaft 606, and its free end 602b is attached to the sheet laminate 51.
The tip Sa of the sheet S is pushed up from below through the elongated hole 515b bored in the sheet S, and the tip Sa is brought into contact with the circumferential surface of the first alignment roller 601 (see FIG. 10). Sheet S is its tip
Sa travels along the third conveyance path D by contacting the circumferential surface of the first alignment roller 601,
The side edge of the advancing side abuts the first sheet stopper 603, and its advancement is stopped. 1st
The excitation time for the plunger 604 is set in advance so that the excitation time of the plunger 604 is such that the excitation is performed until the leading end of the sheet S reaches the first sheet stopper 603.
As described above, the leading edge of the sheet S is first advanced.
After one side edge of the sheet stopper 603 is positioned by contacting the sheet stopper 603, the excitation of the first plunger 604 is released, and the first contact/separation member 602 is moved again below the sheet laminate plate 515. At the same time, the sheet S leaves the circumferential surface of the first alignment roller 601.

Next, the second plunger 704 is excited via a delay circuit (not shown) using the de-energization of the first plunger 604 as a trigger.

By energizing the second plunger 704, the second
The contact/separation member 702 swings around the first stay 705, and its free end 702b moves the side edge of the sheet S downward through another elongated hole 515c bored in the sheet laminate 515. Then, the side edge portion is brought into contact with the circumferential surface of the second alignment roller 701 (see FIG. 11). Sheet S is
When the side edge portion contacts the circumferential surface of the second alignment roller 701, the sheet advances along the fourth conveyance path E, and the side edge Sc along which it advances hits the second sheet stopper 703. In contact, its progress is blocked. Note that, like the first plunger 604, the excitation time for the second plunger 704 is also set in advance so that the side edge Sc of the sheet S reaches the second sheet stopper 703. As described above, when the advancing side edge of the sheet S comes into contact with the second sheet stopper 703, the other edge is positioned, and then the second
The excitation of the plunger 704 is released, the second contact/separation member 702 retreats below the sheet laminate 515, and at the same time, the sheet S separates from the circumferential surface of the second alignment roller 701.

By positioning the two mutually orthogonal side edges of the sheet S as described above, the stacking position of the sheet S on the sheet laminate plate 515 is determined (hereinafter, the sheet S The stacking position is called the third position of the sheet S).

By the way, after the first sheet has passed through each of the above-mentioned transport paths and is aligned at the above-mentioned third position, the second original is copied by the copying machine In the same manner as the sheet, it reaches the third position and is stacked on top of the first sheet. In this way, a predetermined number of copies (according to the number of originals or by setting the copy repeat counter of copy machine X) automatically send the copied sheets to bookbinding machine Y. , will be brought in sequentially)
The sealing device 200 operates with the sheets aligned in the third position (see FIG. 12).

The sealing device 200 in the drawing uses two staplers 201 and one punch 202 (see FIG. 13) to staple and punch sheets (or even just one sheet) stacked at the third position. It has the ability to perform both at the same time.

Each stapler 201 and punch 202 are
They are each driven by the swinging of a swinging rod 205 that swings via a crank mechanism 203 and a connecting rod 204 (see FIG. 13). In addition, each stapler 201 is attached to the second sheet laminate 515.
It is detachably mounted on the upper surface of the side facing the seat stopper 703. Further, each punch 202 is disposed on both sides of the swinging rod 205, and each punch shaft thereof is connected to each stapler 201.
They are located on the inside of each. Each of the stapler 201 and punch 202 is disposed such that the binding portion and punching portion thereof are located above the side edges of the sheets stacked at the third position (see FIG. 13). The marking device 200 uses the exposure signal that is output every time a document is exposed in the copying machine X as a clock pulse, and when the exposure of all the scheduled documents is completed, the operator presses a switch and outputs the seal and stamping command signal as data. However, every time the operation of the buffer memory and the second plunger 704 of bookbinding machine Y is completed, the data is retrieved from the buffer memory, and when there is a signature signal in this retrieved signal, or when there is a scheduled signal. The operator presses the switch when there is a stamping command signal in the signal, or after all the scheduled originals have been exposed and the second plunger 704 of bookbinding machine Y has been activated to align the final copy. The second plunger 704 is activated when an outgoing signature stamping command is issued, and in other cases, for example, when the sheet jams in the middle of each of the above-mentioned conveyance paths, and as a result, the second plunger 704 does not operate, or , if the copy repeat is not completed and copying of the sheet continues, or if the seal stamping command has not been issued, the respective operations are not performed. Therefore, defective binding is reliably prevented, and by not issuing a signature stamping command, it is also possible to perform only folding on the sheet.

Now, as described above, when the sealing device 200 operates in a normal state and sealing (stapling and perforating) sheets is completed, the cam plate 2 rotates angularly in conjunction with the operation of the crank mechanism 203.
06 and the sign operation detection switch 207 (see FIG. 13), an operation completion signal of the sign device 200 is output. This signal causes the stapler 20 to
The stapler remaining amount counter No. 1 is decremented by one, and the third plunger 518 (see FIG. 14)

The claw portions 813a and 913a are engaged with each other.

On the other hand, when the plungers 814, 914 are in an excited state, the claw portions 813b, 913b of the first clutch lever 813 (second clutch lever 913) are engaged.

Note that the first stamping roller 800 and the second stamping roller 900 are selected from one of the stamping rollers set by a stamping selection button (not shown) provided on the side of the copying machine X. Only one of the marking rollers is activated. for example,
If the original to be copied is for commercial use, the first stamp roller 800 is used, and if the original is for real estate, the first stamp roller 800 is used.
The above selection button is selected by the operator so that the second marking roller 900 is activated. By the way, in the illustrated example, the explanation is limited to certified copies and extracts, but the manuscripts and sheets to be copied and bound may be of any kind, such as copies of specifications and the like.

Here, the above selection button is the first stamping roller 80
0, the plunger 814 is once activated when the plunger 814 is in the de-energized state and a commercial extract is selected upon receiving the activation completion signal of the signing device 200.

Then, the first clutch lever 813 is rotated to the left in FIG. come into contact with the object. When the first clutch plate 809 rotates approximately 360 degrees with the claw portion 813a in pressure contact with the peripheral edge of the first clutch plate 809, the notch 812
and the claw portion 813a engage with each other, and the transmission of the rotation of the first stamping pulley 811 to the first clutch plate 809 is cut off again. As the first clutch plate 809 rotates approximately once as described above, the first stamping roller 800 also rotates approximately once, and during this time,
The first stamp plate 802 is brought into contact with the first ink roller 804, and ink is applied to the stamp surface (surface) of the second stamp plate 802b (see FIG. 21).

The first marking roller 800 is temporarily stopped after completing the above-described inking operation (about one rotation from the initial position). Meanwhile, during this period, the sheet S that has been stamped is carried into the stamping section 524 along the fourth conveyance path E, and comes into contact with the inside of the front plate 526 to prevent its progress (hereinafter, this sheet S position is called the fourth position). When the sheet 2 reaches the above-mentioned fourth position and its advancing side edge is detected by the fifth sensor SW ₅ , the first marking plunger 814 is energized again, and at the same time, the first pressurizing Plunger 808 is energized. As the first pressure plunger 808 is excited, the first support rod 806 swings in the clockwise direction as shown in FIG. 22, and the first pressure roller 805 The first sheet mounting plate 530
The sheet S is pushed up from below through the through hole 530a, and the upper surface of the sheet S is first brought into pressure contact with the circumferential surface of the first spacer roller 803. On the other hand, the first
As the stamping plunger 814 is re-energized, the first clutch lever is rotated to the right in FIG. 20, and the claw portion 813a and the notch 812 are disengaged. Further, the claw portion 813b of the first clutch lever 813 elastically abuts against the peripheral edge of the first clutch plate 809. When the claw portion 813a and the first clutch plate 809 are disengaged, the rotation of the first stamping pulley 811 is caused to rotate via the first spring clutch 810.
This is transmitted to the clutch plate 809, and the first stamping roller 800 begins to rotate to the right.

When the first clutch plate 809 rotates approximately 180 degrees, the pawl 8
13b falls into the notch 812 and engages with it. Due to the rotation of the marking roller in conjunction with the rotation of the clutch plate, the sheet S advances along a fifth conveyance path F (see FIG. 1) that is substantially orthogonal to the fourth conveyance path E. In the process of advancing the sheet S, the second stamp plate 802b of the sheet S and the first pressure roller 80

As is clear from the above-mentioned embodiment, according to the present invention, since the stamping roller is disposed at a position that is spaced apart from the sheet, the sheet can be carried into the stamping section extremely smoothly. It is done.

Therefore, the occurrence of sheet jams in this stamping area is significantly reduced, and even if sheet jams occur, since the stamping roller is separated from the sheet, it is extremely easy to take them out, and there is no possibility of unwanted contact with the stamping plate. Damage is also prevented.

Additionally, the pressure roller that brings the sheet into contact with the stamp plate of the stamp roller comes into contact with it in synchronization with the rotation of the stamp roller, so due to its structure, it cannot operate when there is no sheet in the stamp section. There is no dirt on the back of the sheet due to dirt on the pressure roller, and it is also significantly reduced. Furthermore, since it is not necessary to synchronize the operation timing of the stamping roller with the timing of conveying the sheet to the stamping section,
These synchronization mechanisms are not required, simplifying the mechanism, and also eliminating the possibility of misalignment of the stamping position due to synchronization between the stamping roller and the sheet.

Furthermore, the spacer of this stamping roller comes into pressure contact with the sheet only when stamping on the sheet, and separates from the sheet after stamping is completed, so that a complicated mechanism such as an idling mechanism is not required.

In the above embodiment, the sheet is brought into contact with the stamping roller, but in principle, a construction may be adopted in which the edge of the stamping roller is brought into contact with the sheet.

Further, as a means for bringing the sheet into pressure contact with the marking roller, the pressure plate or the sheet mounting plate itself may be moved up and down, instead of using the roller.

Note that the ink application step described above becomes unnecessary when the printing plate itself is impregnated with ink.

Further, according to the present invention, the stated purpose can be achieved to some extent even without the spacer roller.
