DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention receives, from a computer, entry data necessary for issuance on a bill form, such as a single note promissory note or a check, which is mainly provided by a financial institution, and automatically prints and stamps the data. The present invention relates to an automatic check writer, and more particularly to an automatic check writer that automatically prints and seals entries on the bill paper based on entry data from a computer such as a host computer or a personal computer.

[0002]

2. Description of the Related Art Conventionally, an automatic check writer of this type is disclosed in Japanese Patent Application Laid-Open No. 59-29182 and Japanese Patent Publication No. 4-210.
No. 9 publication. These automatic check writers receive entry data required for issuing promissory notes, which are input and stored in a computer, and automatically print the entries on a single-sheet bill paper.

[0003]

However, in such a conventional automatic check writer, a hammer is arranged via a bill paper on a character ring engraved with a numeral or a symbol in each digit of money data to be engraved and printed. Then, the hammer is swung by a solenoid and the bill paper is pressed against the character ring surface, thereby printing the amount of money in the amount column of the bill paper.

Therefore, when adjusting the shading of the notched printing according to the user's request, the mounting position of the solenoid is manually finely adjusted to adjust the pressing force of the hammer, and this adjustment is performed. There is a problem that it is necessary to perform the operation for each automatic check writer one by one, and the workability is not always good.

In addition, since the engraved mark of the character ring is inscribed and a plurality of grooves are formed, if the pressing force of the hammer is too strong, the money amount field of the bill paper may be damaged, while the hammer may be damaged. If the pressing force of the hammer is too weak, the imprint of the engraved printing may be too thin, and adjusting the pressing force of the hammer is not always easy. There is a problem that the efficiency of the force adjustment operation is low.

[0006] Furthermore, there is a problem that a tapping sound is generated when the hammer is pressed against the character ring, thereby generating noise.
For this reason, there is a case where the entire automatic check writer is housed in a soundproof box to reduce noise. However, in this case, there is a problem that the installation space is increased and the cost is increased.

Next, the automatic check writer 1 of the present embodiment
The operation of will be described.

First, the hopper tray 5 is pulled out from the main body case 6 toward the front, and a required number of bill papers 18 are stacked on the inner bottom surface of the hopper tray 5 in a horizontally long state with the front side (card side) facing up, and then the hopper tray 5 is re-mounted. When the hopper tray 5 is pushed back toward the main body case 6, the hopper tray 5 is slightly pushed upward. Then, when the lever in the hopper is pressed down, a feeding roller (not shown) descends on the upper surface of the uppermost layer of the stacked bill paper 16 and comes into contact therewith. Therefore, when the feed roller rotates upon the start of operation, the bill paper 16 stacked on the uppermost layer is sequentially fed in the short direction (longitudinal direction), and the next-stage feed roller 2 is operated synchronously with the feed roller.
2 and is conveyed to the stop roller 23 which does not rotate by pressing against the elastic iron-based alloy. When all the bills 16 on the hopper tray 5 are paid out by repeating this feeding, the hopper end detection sensor 24a outputs the bill paper 16
Is detected, the detection signal is supplied to the control device, and displayed on the operation display unit 10.

Since the smoothness of the stop roller 23 is lower than the smoothness of the feeding roller 22,
By rotating the sheet 2, a plurality of overlapping bills 16 are separated one by one, and then conveyed to a pair of skew correction rollers 24 and 25 which are skew correction means of the next stage. At this time, the leading end of the bill paper 16 being conveyed is detected by the hopper section leading end detection sensor 24, and a slight feed amount of the bill paper 16 by the feed roller 22 is calculated and set based on the detection result.

That is, the bill paper 16 fed by the feed roller 22 to the hopper tip detection sensor 24 side is
If the leading end of the conveying direction is skewed while being conveyed while being inclined with respect to the conveying direction, at the start of operation, the front end of the conveying direction abuts against the pressure contact portion between the pair of skew correcting rollers 25 and 26 that has stopped rotating. The line is modified. Then, a pair of skew correcting rollers are provided in a state where the skew of the bill paper 16 is corrected by feeding the paper by the feed roller 22 by a feed amount set based on the detection result detected by the hopper tip detection sensor 24. It is inserted between 25 and 26 and held.

Next, the pair of skew correction rollers 25,
A double detection sensor 27 detects double or multiple overlaps at the leading end of the bill paper 16 at the start of rotation of the bill paper 26, and when a double or the like is detected, a flashing red light or an alarm sound of the lamp device 9 is output. At the same time, an error is displayed on the operation display unit 10, and the operation of the paper transport device 11 is forcibly stopped. In this case, it is necessary to manually remove the double-printed bill paper 16 from the transport system.

In front of the printing printer 12, the bill paper 16 is erected in a substantially vertical direction by a pair of vertical carrying rollers 28 and 29, and is subsequently carried in the short direction, to the dot printer print head 12 a side of the printing printer 12. Conveyed. The print printer 12 is a line printer that prints the printer data supplied from the data selector 21 by dot printing with a dot printer print head 12a. The printer data is stored in the computer 1 as described above.
The bill format selected by the data selector 21 among the bill formats input and stored in 8 includes an issuer as a drawer, a due date, a tax amount, a bank name, and the like. These printer data are data printed as line data while conveying the bill paper 16 in the short direction. While the print head 12a slides on the slide shaft 12b in the row direction,
At each line feed, the bill paper 16 is intermittently conveyed by the vertical conveyance rollers 28 and 29, printed while being pressed against the peripheral surface of the stamping platen roller 30a, and subsequently the bill paper 16 is conveyed in the short direction by other vertical conveyance rollers. Then, as shown in FIG. When the leading end of the bill paper 16 conveyed to the stamping cassette 13 is detected by the printer exit detection sensor 31, it is determined that printing has been completed, and the bill paper 16 is further moved in the shorter direction by the vertical rollers 32 and 33. While being conveyed along, the seal is stamped by the cooperation of the stamping cassette 13 and the stamping platen roller 34, and the name of the issuer as the dispenser and the seal of the issuer are stamped. At this time, the stamping drum 13a
Are vertical rollers 32, 33 driven by a pulse motor (not shown).
Rotates in the same direction in synchronization with the paper feed of
The outer peripheral surface of the stamp attached to the outer peripheral surface of the ink roller 1
3b is constantly pressed against, and the immortal ink of the required color such as vermilion or black is always supplied.

The stamp cassette 13 and the ink roller 13b are connected to a spline shaft 13 serving as a support shaft.
After being used, the imprint ink cassette 13 can be stored in a safe or the like to prevent theft, and the immortal ink can be appropriately supplied to the ink roller 13b.

After the stamping, when the bill paper 16 is further conveyed in the short direction and hits the upper end of the conveyance, the bill paper 16 will be conveyed in the longitudinal direction in the future, or leftward in FIG. The intermittent printing device 14 intermittently prints the amount data in the amount column while being intermittently fed at the digit feed interval.

FIG. 1 is a plan view of a main part of the notch printing device 14, and FIG. 9 is a front view thereof. As shown in these figures, the outer peripheral surface of the notch printing wheel 14a, which is a character ring, has a size of 0-9.
The symbols necessary for displaying the amount of money such as numbers, ￥ and * are engraved at a predetermined pitch in the circumferential direction, and these engravings have, for example, a plurality of grooves having a triangular cross section as shown in FIG. And are configured with nicks. The outer peripheral surface of the pressure roller 35 is pressed against the notch printing wheel 14a, and the rotation shaft 35a of the pressure roller 35 is driven by the pressure roller driving pulse motor 36 via the driving belt 36a. The notch printing wheel 14a is driven by a notch printing wheel drive pulse motor 37 via a drive belt 37a.
Is driven to rotate in the same direction as the transport direction of the image. The notch printing wheel drive pulse motor 37 is intermittently driven by a print signal for intermittently transporting the bill paper 16 by the paper transport device 11 for each digit of the amount column.
The ink roller 3 is provided on the printing surface of the notch printing wheel 14a.
8 is in contact with the outer peripheral surface so as to always supply immortal ink to the printing surface.

As shown in FIG. 9, the pressure roller 35 has, for example, an eccentric cam 35b integrally formed on a rotating shaft 35a thereof, and a bearing 3 on the outer periphery of the eccentric cam 35b.
A ring-shaped free roller 35d is rotatably fitted to the outside via a ring 5c, and the outer peripheral surface of the free roller 35 is in pressure contact with the outer peripheral surface of the notch print wheel 14a in a freely rotating manner. As shown in FIG. 10, a groove 35e is formed on the outer peripheral surface of the free roller 35d so as to mesh with the groove 14b on the outer peripheral surface of the notch print wheel 14a.

Therefore, by giving a required number of drive pulses to the pressure roller drive pulse 36, the thick top of the eccentric cam 35b can be controlled to an appropriate position, thereby reducing the gap between the eccentric cam wheel 14a and the outer peripheral surface of the notch print wheel 14a. It can be adjusted appropriately. For this reason, this eccentric cam 3
It is possible to appropriately control the gap between the outer peripheral surface of the free roller 35c fitted around the outer periphery of 5b and the outer peripheral surface of the notch printing wheel 14a, that is, the pressing force of the bill paper 16 narrowed by both 35c and 14a. Therefore, it is possible to easily adjust the density of the imprint of the engraved printing.

The engraved printing is performed by the engraved printing wheel 14.
Since the free roller 35c is not pressed against the outer peripheral surface of the free roller 35c rotated by the rotation force and the notch print wheel 14a during the rotation of the "a", damage to the bill paper 16 can be prevented and noise can be reduced. Can be. Therefore, it is not necessary to house the entire automatic check writer 1 in the soundproof box, so that it is possible to save both installation space and cost.

Further, by appropriately controlling the number of pulses applied to the pressure roller driving pulse motor 36, the density of the engraved printing can be adjusted very easily and finely as compared with the conventional example.

Further, since the free roller 35d is freely rotatable, even if an irregular external force is applied to the bill paper 16 held by the free roller 35d and the scribe print wheel, it is not regulated, so that the bill paper 16 is not restricted. Can be prevented from being damaged.

After the engraved printing, the bill paper 16 is continuously transported in the longitudinal direction by the paper transport device 11, bent almost at a right angle at the transport left end at the left end in FIG. 15, and is bent at the front end of the conveyance at a right angle in FIG. 3, and is discharged into the stacker 4 from the discharge port 17. From above and are stored in the stacker 4.

When the automatic check writer 1 is operated in the endorsement mode of the promissory note 16, the bill paper 1
6 is stacked on the inner bottom surface of the hopper tray 5 with its back surface facing upward.

These tickets 16a are conveyed in the transverse direction by the paper conveying device 11 in the same manner as described above, and pass through the printer device 12, the stamping device 13, and the notch printing device 14, respectively. Line optical sensor 39,
39, a blank column of the endorsement column is detected, and the blank endorsement column m becomes the final ticket 16a at the stamped position of the endorsement cassette 15.
Is stopped, and the endorser, the endorsement date, and the seal of the endorser are stamped by the endorsement cassette 15. After this, this ticket 1
6a is transported in the longitudinal direction and discharged into the stacker 4,
Will be accommodated.

Therefore, the single automatic check writer 1 can perform both the front and rear end modes of the promissory note, so that the cost is lower than when a dedicated endorsement machine is provided separately from the front / back end machine. It is possible to reduce the size and save the installation space of these devices.

Since the endorsement cassette 15 is detachable from the main body case 6, it can be removed and stored in a safe or the like to prevent theft.

In the case of a check, similarly to the above-mentioned promissory note, the necessary items for issuing can be automatically printed and stamped on a check sheet (bill sheet).

Since the pressing force of the character ring on the bill paper can be adjusted by controlling the input such as the number of pulses applied to the motor, the adjustment can be performed easily and finely, and noise can be reduced. .

For this reason, there is no need to accommodate the entire automatic check writer in the noise box to reduce the noise, so that the installation space for the automatic check writer can be saved and the cost can be reduced.

Furthermore, since the free roller circumscribing the character ring is free to rotate, even if an irregular external force is applied during the conveyance of the bill paper, it is not restricted, so that jamming and breakage of the bill paper can be prevented.

According to the second aspect of the present invention, it is possible to automatically write the bill on the bill paper by the printing means and the stamping means, and to automatically end the blank of the bill paper by the endorsement means. It can detect and automatically print and seal in the blank.

Therefore, there is no need to provide an automatic check writer dedicated to endorsement separately from an automatic check writer for the front page of bill paper, so that it is possible to reduce costs and reduce the installation space for these automatic check writers.

According to the third aspect of the present invention, it is possible to appropriately adjust the drawer stamp and the stamp position of the bill paper according to the user's request. Further, since the stamping mechanism has an important seal of the drawer attached thereto, after the bill issuing operation is completed, the stamping mechanism can be removed from the main body and stored in a safe or the like to prevent theft.

According to the fourth aspect of the present invention, if the automatic check writer is driven by forgetting to attach the stamping mechanism to the main body, the non-attachment is notified by a display or a sound or the like. Mounting can be prevented beforehand.

According to the fifth aspect of the present invention, when the bill paper is skewed and conveyed, the skew is detected by the skew detecting means, and the skew is corrected by the skew correcting means.
Jams (paper jams) of bill paper due to the skew can be prevented or reduced beforehand. Further, when the skew of the bill paper cannot be corrected, the conveyance of the bill paper is stopped, so that the jam due to the skew can be prevented beforehand, and the damage of parts and the like due to the jam can be prevented.

According to the sixth aspect of the present invention, the hopper into which the bill paper is inserted and the openable cover of the stacker into which the processed bill paper is loaded are locked, whereby the bill paper and the processed bill (check) are locked. Including theft) can be prevented.

According to the seventh aspect of the present invention, the operation status such as whether the operation is performed normally or abnormally is displayed by the display lamp. Therefore, even if the operator of the automatic check writer is away from the automatic check writer, the indicator lamp can be seen from a distance, so that the operation state can be constantly monitored.
