JPS63125373A - Discriminating system for presence or absence of print - Google Patents

Abstract

PURPOSE:To contrive prevention of duplicated printing or unintended skip printing, by discriminating a given condition as presence of print, absence of print or unsettled, based on a signal from a print presence/absence detecting element. CONSTITUTION:Print presence/absence information detected by a print presence/absence detecting element 1 is sent to a print presence/absence discriminating part 2. The discriminating part 2 discriminates a given condition as one of three conditions, namely, presence of print, unsettled and absence of print, and the discrimination result is sent to a controlling part 3, which can take an optimum measure according to the given one of the three conditions. For example, information discriminated as unsettled with respect to the presence or absence of print may be processed by a passbook printer, or may be processed by sending it to a host device. The processing may be flexibly designed according to the type of transaction, the amount of transaction or the like, whereby it is possible to efficiently guide the user to a window or the like. Thus, when the discrimination of the presence or absence of print is impossible, the condition may be discriminated as unsettled, followed by determination of the subsequent disposition, so that it is possible to avoid unintended skip printing or duplicated printing, which has been generated in a conventional system.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method for determining the presence or absence of printing, and particularly to a method for determining the presence or absence of printing that is suitable for reliably determining the printing of a passbook printing device in a bank terminal. .

[Prior Art] Conventionally, passbook printing devices for bank terminals use an impact method to print transaction details on a passbook by bringing a print head into contact with an ink ribbon or the like. When printing a passbook using such a passbook printing device, first, a general user inserts the passbook into the printing device and uses an optical sensor or the like to determine whether or not there is printing on the passbook. By determining the presence or absence of printing, a line without printing is found, and that line is used as a print line to print the transaction details processed by the host device.

The above-mentioned printing presence/absence determination method is, for example, as described in Japanese Patent Publication No. 61-5198 and Japanese Unexamined Patent Publication No. 52-82129, which uses an optical sensor or the like to detect the presence or absence of printing at a specific location on the surface. There are known devices that determine the presence or absence of printing based on reflectance.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional technology, the sensitivity of the optical sensor affects its judgment criteria, and increasing the sensitivity will cause problems such as dust, etc.
There was a problem in that it could detect even the smeared print on the back side and determine that there was a print even if there was no print, or conversely, if the sensitivity was lowered, the presence of print would be judged as absent, causing skipped prints and double prints. .

The purpose of the present invention is to solve such conventional problems, and to provide a printing presence/absence determination method that can prevent skipped printing and double printing in a passbook printing device, etc., and can determine the presence or absence of printing more reliably than before. be.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention includes a printing presence/absence determining means for determining the presence or absence of printing on a bankbook, etc. based on a signal from a printing presence/absence detecting element, and after the determination, prints on a desired line of the bankbook, etc. In the printing device, the printing presence/absence determination means is characterized in that, in addition to determining the presence or absence of printing on a passbook or the like based on the signal from the printing presence/absence detecting element, the printing presence/absence determination means also determines whether printing is undetermined.

[Effect]

In the present invention, the printing presence/absence determining means operates to determine whether printing is present or not, or whether it is indefinite, based on the signal from the printing presence/absence detection element. As a result, when the presence or absence of printing cannot be determined, conventionally it was judged as one or the other, so it is determined that there is no printing even though there is no printing, or it is judged that there is no printing even though there is printing, respectively. However, in the present invention, the presence or absence of printing is determined to be indeterminate, thereby preventing the above-mentioned malfunction.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

First, the present invention will be explained in detail.

Conventionally, when detecting the presence or absence of printing, light is applied to a printing presence/absence detection surface, and the presence or absence of printing is determined based on the intensity of the reflected light. However, in this method, the problem is at what level of intensity of reflected light the presence or absence of printing is determined. i.e. 1
When the judgment level is lowered, it is judged that there is no printing even though there is printing, and on the other hand, when the judgment level is raised, there is bleeding of the back printing.

Due to dust, etc., it is determined that there is printing even though there is no printing, and there is always an error in the setting of this judgment level value. This is due to the fact that there is only one option, with or without printing, and this is caused by the strength of the reflected light.
This can be resolved by increasing the detection level.

Therefore, in the present invention, in addition to areas with or without printing, an area with undefined printing is provided depending on the intensity of reflected light, and in addition to areas with or without printing, indeterminate printing is determined, thereby solving the above problem. , If this printing is determined to be undefined, the system will take the most appropriate action.

FIG. 1 is a diagram for comparing and explaining a printing presence/absence judgment method showing an embodiment of the present invention and a conventional printing presence/absence judgment method, in which (a) shows the present embodiment, and (b) shows the conventional example. It shows. This shows a partial configuration of a print determination unit such as a passbook printing device of a bank terminal.

In Figure 1, 1 is a print detection element that detects the reflected light from the print presence/absence detection surface of a passbook, etc., and 2 is a print presence/absence detection element l.
3 is a control unit which determines whether or not to print based on the amount of reflected light detected by the printer.

4 to 6 are signals output by the printing presence/absence determination section 2, 4 is a printing presence signal, 5 is a no printing signal, and 6 is an undefined signal indicating that the presence or absence of printing is uncertain.

Hereinafter, the operation of this embodiment will be explained while comparing it with the conventional example.

In this embodiment, as shown in FIG.
sent to. Based on the above-mentioned information, the print presence/absence determination unit 2 makes three types of determination: print presence, indeterminate, and no print, and then controls the control unit 3.
The system can handle the three cases described above in an optimal way.

In the conventional method, as shown in FIG. 1(b), since there were two types of printing: with printing and without printing, there was a problem that skipped printing or double printing occurred. However, in this embodiment, when it is impossible to determine the presence or absence of printing, it is determined that M is undefined, and the subsequent treatment can be determined.
This has the advantage of preventing double printing. In the passbook printing process, if skipped printing or double printing occurs, the passbook must be reissued, but users will have to wait for a long time for this procedure. The advantage of being able to prevent such serious problems is of great value.

Further, the information determined to be printed or not may be processed by the passbook printing device, or may be transmitted to a higher-level device and processed by the higher-level device. As for the processing method, flexible methods can be considered depending on the type of transaction, transaction amount, etc., and it is possible to guide users to counters etc. more kindly and efficiently, making a great social contribution.

〔Effect of the invention〕

As explained above, according to the present invention, when it is difficult to determine the presence or absence of printing in a passbook printing device, etc., the so-called , has the effect of preventing double printing, and also has the effect of preventing so-called skipped printing, in which it is determined that there is printing even though there is no printing, and the - line is skipped.
