Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a printing device capable of printing on a booklet such as a bankbook etc. in which multiple sheets of paper are bound together. The present invention relates to a booklet printing device that is effective for a passbook printing device using a non-impact printing method.

[Conventional technology]

Currently, the wire dot printing method is mainly used as a printing method for printing on booklets made of bound sheets of paper, such as passbooks. For example, the special public service 59-158
As shown in Publication No. 33, a bankbook whose thickness varies depending on the page to be printed is pressed against a reference guide by a platen, and the printing surface is always kept at a constant position, and printing is performed by a wire dot printing method printing means. Are known.

This printing method has the feature that it is possible to easily provide a device that can print clearly even on print media of varying thickness.

Another known printing method is the thermal transfer method.
This system is characterized by low printing noise, as disclosed in Japanese Patent Application Laid-Open No. 56-34465. This method prints by moving the thermal print head that prints one line in the line direction, but when changing the passbook after printing, it is necessary to release the pressure on the thermal print head.

[Problem that the invention seeks to solve]

In the case of the conventional method described above, in the case of the wire dot printing method, when changing the line of the bankbook, it is necessary to release the pressed bankbook from the suppressed state, which increases the operating time, and the thermal transfer method When changing the passbook after the printing operation, it is necessary to release the suppression of the thermal print head, and as with the wire dot printing method, there is a problem in that it is difficult to improve processing performance.

As a printing method that does not require releasing the suppressed state of the thermal print head when changing the paper, a line-tod type thermal ink film 7 is attached to a platen roller 9 by a spring 10, as shown in FIG. A line-tod type thermal printer that constitutes a printing mechanism that presses the print head 1 to perform printing is known as a well-known technique.

This printing operation is performed using a thermal print head (hereinafter referred to as thermal head 1).
Printing is performed by pressing a printing paper 8 against a platen roller 9 with a spring 10 or the like via a thermal ink film 7 coated with an ink that melts the heating resistor part on the upper part of the heating resistor section (referred to as a heat generating resistor) by heat. Rotate the platen roller 9 to print the printing paper 8 and the thermal ink film 7 at the same time.

and is carried out by sending it continuously. In other words, this printing method has the feature that it is possible to perform high-speed printing operations because it is not necessary to release the suppressed state of the thermal head 1 during paper feeding operation.

However, as shown in Figure 6, this printing method has the following problems when applied to a printing device that must print a booklet made by binding multiple sheets of paper, such as a passbook 11. be.

As is well known, in order to obtain clear prints using a thermal printer, it is necessary to improve the adhesion between the print paper and thermal ink film and the thermal head. Therefore, when printing on multiple sheets of paper such as bankbooks, it is necessary to press the thermal head 1 with a large pressing force on each bankbook.
The heat generating resistor 2 portion of the thermal head 10 does not come into close contact with the thermal ink film 7 and the bankbook 11.

When the platen roller 9 is rotated and the passbook is sent while keeping the passbook and thermal ink film pressed with such a large pressure force, the inner paper 17, which is the printing paper for the passbook 11, is usually a relatively thin paper. Because of this structure, a phenomenon occurs in which the inner paper 17 shifts during the feeding operation and bulges as shown in FIG. This causes printing misalignment and jamming of the passbook or thermal ink film.

In order to solve this problem, it may be possible to print by reducing the pressing force of the thermal head to some extent, but in this case, the adhesion between the passbook and thermal carbon paper and the thermal head will deteriorate, resulting in poor printing. It becomes unclear. To solve this problem, it is possible to print with a large amount of printing energy by increasing the duration of the energizing pulse applied to the heating resistor of the thermal head, but in this case, the printing speed will naturally become slower, which is expected. High-speed printing becomes impossible.

It should be noted that this problem of the inner paper of the passbook shifting and bulging during the creation of prints is not limited to the thermal printing method, but also occurs in other contact printing methods.

SUMMARY OF THE INVENTION An object of the present invention is to provide a printing device that prints on booklets such as bankbooks, which are made up of multiple sheets of paper, using closely-contact printing elements that can operate at high speed. A specific example of the present invention is to provide a low-cost printing device that is capable of printing on each square using a relatively low-cost printing element such as a thermal head.

[Means for solving problems]

In order to eliminate the above-mentioned problems, the present invention, when printing on a printing paper made of multiple sheets stacked together like a passbook, pinches the printing paper on the opposite side of the printing element and the binding line of the paper. It is characterized by having a means.

[For production]

By holding a bulky booklet with multiple sheets of paper between them before starting printing with the close-contact printing method, the relative speed between the printing element and the booklet causes the inner paper, which is the printing paper of the booklet, to shift and bulge during printing. prevent the occurrence of This prevents printing misalignment and jamming, ensures good adhesion between the printing element and the inner paper, which is the printing paper of the booklet, and enables clear printing.

〔Example〕

Hereinafter, an explanation will be given of a stumbling block configuration of an embodiment of the present invention with reference to FIGS. 1 and 2. In FIG. 1, the thermal head 1 uses an end-face type thermal head in which a heating resistor 2 is located on the end face of the thermal head 1. A suppressing spring 21 is attached to the thermal head 1, and a suppressing 0N-OFF mechanism 22 for activating and releasing the pressed state can be operated in conjunction with the suppressing spring 21 (the suppressing 0N-OFF mechanism is composed of a solenoid, etc.). possible, □□□indication is omitted). The platen roller 9 is made of elastic material with low hardness and is supported to rotate freely. The thermal ink film 7 is disposed between the thermal head 1 and the platen roller 9, and is wound up from a paper feed side roll (not shown) to a winding side roll (not shown) according to printing, and advances in the direction of arrow 7a. (Although a motor or the like is used as the IIA driving means of the take-up roll, illustration thereof is omitted.) The passbook 11 is inserted between the platen roller 9 and the thermal ink film 7 in the direction of the arrow 11a.

The sandwich holders 23 and 24 are arranged on the opposite side of the thermal head 1 and the platen roller 9 from which the passbook is inserted. The positions where the holding bodies 23 and 24 are arranged are such that when the first line printing position of the passbook is at the position of the heating resistor on the thermal head 1, the ends of the passbook can be held between them. Generally open top and bottom 'I! In the case of one book, the first line printing position is approximately 20" from the edge of the passbook,

.

Sandwiching mechanism (as shown in Fig. 2, holding bodies 23, 24,
It is mounted on a carrier 30 composed of a clamping spring 26 and a clamping ON-OFF mechanism 25, and is configured to be movable on support rails 27a and 27b. The carrier 30 is configured to be movable in the direction of an arrow 29 by a driving means (not shown) such as a motor.

Next, the operation of this embodiment will be explained. Suppression 0N-OFF・
The suppression of the mechanism 22 is released, a gap is created between the thermal head 1 and the platen roller 9, and the pinching state is 0N-OFF.
The passbook 11 is sent to the initial printing position with the mechanism 25 released and a gap left between the holding bodies 23 and 24. Passbook conveyance means (usually done by a roller mechanism, etc., but not shown). The initial printing position is a position where a predetermined line can be printed when the thermal head 1 is pressed against the passbook 11 in that position. At this time, the tip of the passbook 11 is between the holding bodies 23 and 24, and the holding position is 0N-O.
The FF mechanism 25 is operated and the passbook 11 is pinched and clamped by the holding members 23 and 24. After that, suppression 0N-OF

to press. Next, while moving the carrier 30 equipped with the holding mechanism in the direction of arrow 29, the thermal head 10 and the heating resistor 2 are driven to melt and transfer the heat-melting ink of the thermal ink film 7, thereby printing on the passbook 11. .

This printing process is the same as the well-known thermal transfer type thermal printing method. The platen roller 9 is through 111
Since the JJII is clamped and pulled by the holding bodies 23 and 24, it is not pressed along the cover 16 of the pass@11 and is spinning idly.

As described above, since the cover 16 and inner paper 17 of the passbook 11 are clamped by the holding members 23 and 24, the inner paper 17 will not shift or bulge during the printing operation, ensuring good printing. can. Also, passbook 11 has fold 1
2, the inner paper 17 and the cover 16 are bound, so when printing on the next page beyond the fold 12, the binding part of the fold 12 prevents the inner paper 17 and the cover 16 from shifting. , the inner paper 17 will not bulge.

Looking at the speed of printing operation, that is, the printing processing performance, under the conditions that the number of characters printed per bankbook line is 60 characters and the line spacing of the bankbook is 5111, the case of the existing technology wire dot printing method and the case of this example are as follows. A comparison of the printing speeds is as follows. In the case of wire dot printing, if the printing speed of the print head is 120 characters/second, -
The line printing time is approximately 0.5 seconds.

In the case of the thermal printing method of this embodiment, the operating speed of the thermal head can normally be about 5 ms/line. - Assuming that 36 lines are printed per line (this corresponds to printing dots at approximately 1/180 inch intervals), the printing time for one line in the thermal printing method is 5 x 36 = 180 m, s or 0.18 It is possible to print at a speed approximately 2.8 times faster than the wire dot printing method.

In addition, unlike the conventional wire dot printing method described above for bankbook printing, the action of releasing the platen pressing force every time the paper is changed is no longer necessary with the thermal printing method used in this implementation. When comparing the processing performance, it is clear that the processing performance is even higher.

As described above, this embodiment uses a thermal head that can be obtained at a relatively low cost, and has the major feature of ensuring high-speed printing with good print quality on a passbook. Examples will be described with reference to FIGS. 1 and 3. FIG. 3 shows a perspective view of this embodiment, and the difference in construction from the previous embodiment is as follows. The printing mechanism parts of the platen roller 9, the thermal head 1, the suppression ON-OFF mechanism 22, and the thermal ink film 7 shown in FIG.

It is configured to be movable on 33b. The carrier 32 is movable in the direction of the arrow 31 by a driving means such as a motor (the number 1 is omitted).

Next, the operation of this embodiment will be explained. The carrier 32 is moved to the initial printing position, and in this state, the passbook 11 is placed in the same manner as in the previous embodiment.
is sent to the printing position, the clamping ON-OFF mechanism is activated, and the passbook is clamped between the clamping bodies 23 and 24.

Next, the suppression ON-OFF mechanism 22 mounted on the carrier 32 is activated to press the thermal head 1 against the passbook 11, and the printing operation is performed while moving the carrier 32 in the direction of the arrow 31.

This embodiment also provides exactly the same effect as the previous embodiment.

FIG. 44 shows still another embodiment of the present invention.

5 and 36 for conveying the passbook 11. Here, the roller 36 is driven, and the roller 35 pinches and conveys the bankbook 11 by the pressure spring 34. At this time, be careful of the following points:
It is necessary to set z so that it is larger than Fl of the platen and head, and furthermore, F2 is
After determining the conveyance accuracy of 1, and carefully examining the relationship between Fl (as it is determined by the pressing force and friction coefficient of the head and platen, it affects the print quality, conveyance rW i-c, print quality and Q). must be decided.

By setting Fl and F2 to have the above-mentioned relationship, the same effect as in FIG. 1 can be obtained.

It can be realized with a simpler structure than that shown in FIG. 1 (only the roller B36 is driven) and the driving force is small.

The embodiments described above use the printing principle of the thermal printing method as the printing element. Even if the printing method V' is used, it can be used without any effective effect.

This is Aokari's printing method Q) As an example, the printing paper is
The electrostatic printing method using a resistor, the discharge destruction printing method using discharge destruction paper, and even the printing method Q3 using the ``4-child feeding method'' are capable of printing at high speeds. We offer commercial printing quality 1pfk printers, etc. - It has the characteristic of being able to print well.

〔Effect of the invention〕

As mentioned above, by virtue of the invention, the so-called non-impact printing method, which prints in close contact with the printing paper, is used as the printing element, and the printing machine is configured to have a simple structure without hindering the characteristics of high-speed printing at all. This makes it possible to maintain good control of the printing elements and printing paper even when using multiple sheets of paper, ensuring excellent printing quality with no printing gaps, and low-cost printing. This has the great effect of making it possible to obtain a printing device that is highly configurable.
