BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to FIG.
From FIG.

FIG. 1 shows a conveying path 1 for conveying a medium such as a passbook and a set of conveying rollers 2a to 2d, and a page turning mechanism section 13 for turning the medium to print on a desired page of the medium. A print head 3 for performing desired printing on the rolled-up page,
It is a cross section of a passbook handling device provided with a control circuit 4 for controlling them. FIG. 2 is a perspective view showing the main part of the present invention.

However, the gap adjusting mechanism is shown in two views in FIG. 4 and 5 are side views showing the page turning operation status of the present invention, FIG. 6 shows the relationship between the page turning failure rate and the page turning shutter opening / closing degree, and FIG. 7 shows a sensor for detecting the page turning state and the page turning. FIG. 8 shows the relationship between the degree of opening and closing of the shutter, the relationship between the page-turning failure rate with respect to the frictional force of the page-turning roller and the rotation speed of the page-turning roller, and FIG. The relationship between the gap between the roller and the medium is shown in the graph. FIG. 10 is a block diagram relating to control. FIG. 11 shows an example of the condition sequence for page turning adjustment, and FIG.
Shown in 2.

The passbook handling device 5 includes a medium insertion port 6, conveying roller groups 2a to 2d, and a print head 3 for conveying a medium 7 such as a passbook inserted from the medium insertion port 6 by a known method. It is possible to move to the printing unit 3x by the roller sets 2a to 2d and perform printing with the print head 3.

Although not shown in FIG. 1, a page mark read mechanism, a magnetic stripe read / write mechanism, a printed line detection mechanism, etc. may be arranged on the transport path 1 of the passbook handling device 5.

According to the present invention, it is easier to turn the page when the page turning roller 8 is rotated slowly, and the page turning roller 8 pushes the medium 7 by changing the gap between the page turning roller 8 and the medium 7. It relates to the ability of the device to adjust the applied force.

Regarding the setting of the page turning roller rotation speed ω and the gap g at the time of shipment of the apparatus, the faster the page turning roller 8 rotation speed ω is, the more advantageous in terms of processing speed, and the page turning roller 8 and the medium are set. As for the gap g of 7, the wider the gap g, the lower the pressure of the page turning roller 8 for pressing the medium 7 is, so that the medium 7 is less likely to be soiled, and further, it is advantageous for the life of the page turning roller 8.
The gap g is set in a wide direction, and as will be described later, the shutter 9 of the page turning portion is set to have an appropriate opening / closing degree θa. The factory set values are shown in FIG. 11, where the page turning roller rotation speed ω0 and the gap g0.

When printing on a desired page of the medium 7 in FIGS. 1 and 2, the medium 7 is inserted from the medium insertion port 6 and moved to a desired position by the conveying roller sets 2a to 2d. If any line of the inserted medium 7 has already been printed on all lines and additional printing is not possible, or if printing on the last line of one page is completed and printing of the next page is required, etc. In, the medium 7 is moved to a predetermined position of the automatic page-turning mechanism section 13 provided at the rear of the apparatus by the transport roller sets 2a to 2d. The automatic page turning mechanism section 1
Reference numeral 3 denotes an openable and closable shutter 9 provided for bending the inside paper of the medium 7 above the conveying path 1 for page turning and having the purpose of preventing page jams and the page turning space.
It is equipped with a page turning detection sensor 11 which is a reflection type photo-coupler for detecting the opening / closing degree, and is further equipped with a drive motor 10 for rotating a page turning roller 8 rotatable in forward and reverse rotation directions. The automatic page-turning mechanism section 13 separates the inside paper 12a desired to be turned over from the inside paper 12a desired to be printed next by the page-turning roller 8 from the medium 7 moved to a predetermined position, and further rotates the page-turning roller 8. Automatically turns pages.

At this time, the shutter 9 is opened and closed centering on the fulcrum 9a of the shutter mounting portion along with the bending of the inside paper 12a to be turned up. The opening / closing amount of the shutter 9 at this time is measured by the page turning detection sensor 11. To do. Specifically, the shutter 9
The relationship between the opening / closing degree of the page turning detection sensor 11 and the voltage output level of the page turning detection sensor 11 is proportional to the physical distance between the shutter 9 and the page turning detection sensor 11 (FIG. 7). I understand.

The voltage level of the sensor output measured by the page turning detection sensor 11 is transmitted to the arithmetic unit 4a of the control circuit 4 (FIG. 10). The arithmetic unit 4a of the control circuit 4 compares and determines whether or not it is within the proper opening / closing degree range θa based on the sensor output result. If the comparison judgment result is within the defined opening / closing degree range θa, the page turning roller rotation speed and the gap between the page turning roller 8 and the medium 7 remain at the current values. As described above, the apparatus constantly monitors the page turning state, but the series of control operations are performed by the program 4d section incorporated in the control circuit 4.

FIG. 4 shows a case where the page turning state is proper and the page turning is normally performed with the proper page turning roller rotation speed ω and the proper gap g is set, and FIG. 5 is the case where the page turning is normally performed. It shows the case where it has not been done.

In FIG. 4, the opening / closing degree θ ′ of the shutter 9 which opens and closes in accordance with the curved state of the inside paper 12 during page turning in the automatic page turning mechanism 13 is rotated by the page turning roller 8 to the page turning determination point φd. At that time, the page turning detection sensor 11 measures, the result is transmitted to the control circuit 4, and the arithmetic unit 4a compares and determines whether or not it is within the specified opening / closing degree range θa.
If the opening / closing degree θ ′ is the appropriate opening / closing degree range θa shown in FIG. 6, the page turning roller rotation speed ω and the gap g are not changed.

On the other hand, as shown in FIGS. 8 and 9, when the page turning roller 8 becomes dirty due to long-term use or the frictional force μ of the page turning roller 8 decreases due to deterioration over time,
The page failure rate tends to increase. Contamination and deterioration of the page turning roller 8 gradually progress, and the gradually turning page turning by the page turning roller 8 approaches the page turning detection sensor output V0 to V1 as shown in FIG. This sensor output V1 is set as a review point of the page turning condition, and at this time, automatic adjustment is performed to optimize page turning described later. In addition, depending on the medium used, the default setting is as shown in FIG.
It is also conceivable that page turning as shown in (4) may occur. In the case of the page turning incomplete state such as the opening / closing degree θ ″ of the shutter 9 shown in FIG. 5, the page turning detection sensor output V ″ at the time when the page turning roller 8 is rotated to an arbitrary point φd
7 is low as shown in FIG. 7, and in this case, the opening / closing degree θ ″ exceeds the proper opening / closing degree range θa as shown in FIG. 6, and it can be determined that the page turning failure rate is high. If it is transmitted to the control circuit 4 and the opening / closing degree range θa is judged whether or not it is outside the appropriate opening / closing degree range θa shown in FIG. Since the rate increases, the page turning roller 8 is immediately reversely rotated to the standby position φ0 by an instruction from the control circuit 4, and the page turning is stopped.

As the next operation, automatic adjustment is performed to optimize the page turning state. The adjustment items are the page turning roller rotation speed ω,
And the gap g, and the rotation control of the page-turning roller driving motor 10 that drives the page-turning roller 8 is controlled by the control circuit 4.
This is performed by the page turning roller drive motor driver 4h. The page turning gap adjusting mechanism will be described with reference to FIG. 3. The page turning gap adjusting mechanism also serves as a part of the conveyance path 1, and the eccentric camshaft 14 and the eccentric cam shaft 14 for adjusting the gap between the page turning roller 8 and the medium 7. , An eccentric camshaft drive motor 15 for rotating the eccentric camshaft 14. Further, the rotation speed ω of the page turning roller 8 is set at the time of shipment to the page turning roller rotation speed ω0 in five stages (rotational speeds ω1 to ω
5), and the gap g can be adjusted to three levels (gap g1 to g3) by setting the gap g0 at the time of shipment. The rotation position and speed of the page turning roller, adjustment of the gap, and the like are adjusted by the roller drive motor 10 described above, and
The eccentric cam shaft drive motor 15 and position sensors (not shown) for them are used, but details thereof are not directly related to the present invention and are omitted since they are prior art.

FIG. 11 shows that the adjustment level Ln is set by stepwise combining the page turning roller rotation speed ω and the gap g. The control flow of this adjustment is shown in FIG.
The page-turning roller drive motor 15 rotates the page-turning roller 8 in the forward direction, and when the rotation angle of the page-turning roller 8 reaches φd, the opening / closing degree θ of the shutter 9 is measured. The determination is transmitted to the control circuit 4, and it is determined whether or not it is within the proper opening / closing degree range θa. If the opening / closing degree range is appropriate, the page turning is continued and the page turning roller rotation speed ω at that time is continued.
And the gap g as page turning conditions, the memory 4 of the control circuit 4
Store in c.

However, when the measurement result of the opening / closing degree θ of the shutter 9 exceeds the appropriate opening / closing degree range θa (opening / closing degree θ ″ shown in FIG. 6), the page turning roller drive motor 15 causes the page turning roller 8 to move in the opposite direction. It rotates and returns the page turning roller 8 to the position φ0 at the time of standby.Here, the page turning roller rotation speed ω and the gap g are adjusted.Advancing by one step from the previous adjustment level Ln, under the adjustment condition of the adjustment level Ln + 1. again,
The page turning is executed to determine whether or not it is within the proper opening / closing degree range θa. As for the adjustment order of the adjustment level Ln, as shown in FIG. 11, the adjustment level L1 to L8 are sequentially advanced step by step, and the adjustment condition at the time when the proper opening / closing degree range θa is reached is set to the page turning condition as the page turning condition. 4c, and always maintains the optimum page turning accuracy .

A feature of the present invention is that the page itself is always managed by the apparatus itself.

As one form of this embodiment, in this embodiment, a reflection type photocoupler is used as a sensor and a page turning shutter is used to stabilize the output regardless of the reflectance of the page turning medium. For confirmation, there is a means for directly detecting the inside paper with a sensor without using the shutter, and a means for detecting the curving height of the inside paper when a page is turned by the sensor. Further, although the embodiment using the eccentric cam shaft for adjusting the gap between the page turning roller and the medium has been described, the means for moving the page turning roller in the vertical direction and the conveyance path itself in the vertical direction are used for the gap adjustment. There are also such means.

The page turning of the medium 7 such as a passbook is caused by the stiffness of the medium paper 12 of the medium, the difference in frictional force between the medium paper 12a and the medium paper 12b to be rolled, and the continuous medium paper 12c, and deformation or damage. It is affected by the state, and further by the surface dirt and deterioration of the page turning roller 8 provided in the page turning mechanism section 13 of the apparatus 5. Maintaining the quality of page turning accuracy by managing the page turning state according to the present invention for page turning under various conditions as described above, and determining and executing the optimization of the processing speed by the apparatus itself,
Further, it is useful in that the cycle of replacing the page turning roller 8 can be extended. In addition, an alarm for replacing the page turning roller 8 can be given when the rotation speed ω and the gap g adjustment approach the limit level.

[0025]

According to the present invention, in a passbook handling device with a simple structure, the quality of automatic page turning accuracy of a medium having a middle paper such as a passbook is maintained, and pages at the best processing speed are obtained. It can be turned over and can be maintenance-free for a long period of time.
