Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an image reading apparatus provided with a magnetic ink character data reading mechanism, and more particularly to a mechanism for efficiently reading a character string formed by a magnetic ink written on a document to be read. The present invention relates to a method for controlling an image reading device having a character data reading mechanism.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as in the processing of securities or bills, for example, a technical idea of coexisting means for reading an image and means for reading magnetic ink character data in the same device has been known. Reference 1 and Patent Document 2).
[0003]

JP-A-9-282587
[0004]
Here, the definitions of the following terms according to the present invention applied here and the technical background thereof will be described to clarify the concepts included therein.
[0005]
The forward direction, the backward direction, and the traverse direction are each defined as a concept that defines a direction in which an object is moved.
[0006]
Here, the forward direction is defined as a forward direction in a document transport type image reading device, in which the direction along the transport direction in which the document supplied to the image reading device is discharged through the image reading line is defined as the forward direction. The direction opposite to the forward direction is defined as the reverse direction. The traverse direction is defined as a direction orthogonal to the forward direction or the reverse direction.
[0007]
In the flat-bed image reading apparatus, a moving direction in which the image reading unit moves from the initial reading start position in accordance with the image reading is defined as a forward direction.
[0008]
Therefore, the backward direction in the flatbed type image reading apparatus indicates a direction opposite to the forward direction, and the traverse direction is defined as a direction orthogonal to the forward direction or the reverse direction.
[0009]
The magnetic ink character data reading mechanism is a mechanism for magnetically reading data described by magnetic ink on a medium.
[0010]
Checks or bills are printed with character data using magnetic ink and visually read and magnetically read.
[0011]
The character data by the magnetic ink is a character string composed of characters in a specific typeface that is defined in advance by an ink containing a magnetic material.
[0012]
Characters in a specific typeface used for character data by the magnetic ink correspond to reading visually, and at the same time, a reading mechanism corresponding to the magnetic ink presents a reading output value corresponding to the character, thereby magnetically reading. It corresponds to.
[0013]
That is, a magnetic ink character data reading head for reading character data by the magnetic ink includes a magnetizing head for magnetizing a magnetic substance contained in ink constituting a character pattern to be read in a predetermined direction, and a magnetizing head for magnetizing the magnetic material. And a magnetic field reading head that electromagnetically reads the change in the magnetic field when the magnetic material passes.
[0014]
Since the magnetic ink character data is composed of a magnetic substance contained in the magnetic ink and is magnetized immediately before reading, it is difficult to set a high data recording density. It has the feature that there is little possibility of magnetic destruction and it is difficult to alter or tamper with it.
[0015]
However, in order to realize the mechanism for reading the magnetic ink character data described above, if the magnetic ink character data reading head disposed at a position facing the character string is inclined with respect to the character, the read output waveform is distorted. There is a constraint that the read output value obtained from the read head decreases as the relative moving speed with respect to the head used for reading decreases.
[0016]
Thus, as a condition necessary for the mechanism for reading magnetic ink character data, a magnetic ink character data read head having the same direction as the magnetic ink character string to be read is read and moved along the magnetic ink character string. And read the magnetic ink character data at a sufficiently high speed.
[0017]
A configuration of an image reading apparatus provided with a magnetic ink character data reading mechanism according to a conventional technique and a control method thereof will be described with reference to FIGS.
[0018]
Conventionally, image reading devices applied to an image reading device having a magnetic ink character data reading mechanism are often found in a document conveying type image reading device. A configuration including a mechanism will be described.
[0019]
As described above, forms as documents that require reading of magnetic ink character data are often found in checks or bills, and the printing position of the magnetic ink character data is at a predetermined distance from the end of the sheet. Therefore, in order to process a large number of forms efficiently, the printing position of the magnetic ink character data is set to a predetermined distance from the edge of the sheet.
[0020]
As shown in FIG. 18, an image reading apparatus of a document transport type having a magnetic ink character data reading mechanism includes a fixed document guide 71b and a movable document guide 71a in a document supply mechanism.
[0021]
The original 1 guided by the fixed-side original guide 71b and the movable-side original guide 71a is conveyed in the apparatus by conveying rollers 72a, and after being subjected to image reading over the entire area of the original surface by the image reading line 73, is conveyed. The transport is further continued by the roller 72b, and the magnetic ink character string 2 is magnetically read by the magnetic reading unit 74.
[0022]
An original document 1 having a width of W has a magnetic ink character string 2 at a position at a predetermined distance D from the end. In general, the width W of the form as the document 1 varies depending on the type of form to be applied, but the distance D at which the magnetic ink character string 2 is arranged is often a fixed value. Therefore, by defining the positional relationship between the fixed-side document guide 71b and the magnetic reading unit 74 by the distance D, most of the magnetic ink character string data can be read.
[0023]
Also, in general, in a document conveying type image reading apparatus using a conveying roller, a mechanism for moving the left and right document guides in an evenly interlocked manner so as to read a document to be read at the center of the reading section, that is, a center distribution mechanism. In many cases, a mechanism is provided to make the center of the document coincide with the center of the reading unit.
[0024]
By taking measures by the above-mentioned center distribution mechanism, the reading unit always reads in the central part where the output characteristics of the reading element are stable, and the document conveyance system is skewed by symmetrically arranged conveyance rollers. And a mechanism for stably transporting the original can be easily realized.
[0025]
However, in the image reading apparatus including the fixed document guide 71a and the movable document guide 71b for setting the magnetic ink character data reading position as in the apparatus shown here, measures by the above-described center distribution mechanism must be taken. It is difficult.
[0026]
Of course, if the image reading device sets the speed at which the document is conveyed to read the image optically, the definition of the image data is reduced, and the document is read in order to magnetically read the magnetic ink character data. If the conveying speed is set to a low value, the read output value decreases, making reading difficult.
[0027]
Thus, in the image reading apparatus which is a document transport type image reading apparatus and includes a magnetic ink character data reading mechanism, when setting the document transport speed, the optical reading speed and the magnetic reading speed are set to be equal to each other. It must be determined in consideration of the balance between the two.
[0028]
That is, a speed value at which magnetic ink character data can be read is set within a speed range in which the document can be optically read. Naturally, the document conveyance speed set here is a speed value that withstands optical reading while also withstanding optical reading. The optimal transport speed for reading is also lost.
[0029]
As a matter of course, it is possible to obtain the most stable quality of image data by applying the optimum transport speed for optically reading an image, and to apply the optimal transport speed for magnetic reading. It goes without saying that the most stable quality of read data can be obtained.
[0030]
Also, if a flatbed type image reading apparatus is equipped with a magnetic ink character data reading mechanism, it is difficult to specify the position of the original to be read and the orientation of the original to be placed. It is difficult to specify a relative positional relationship with the magnetic reading mechanism, and it is difficult to provide a magnetic ink character data reading mechanism.
[0031]
Based on FIGS. 19 and 20, an image reading apparatus according to the related art, which is a document conveying type image reading apparatus and includes a magnetic ink character data reading mechanism, optically and magnetically reads a document to be read. The control procedure will be described.
[0032]
The components will be described based on the block diagram shown in FIG. The arithmetic control unit B071 incorporated in the image reading device B070 includes a character pattern B071a and a transport speed B071b.
[0033]
The character pattern B071a stores an individual output pattern based on magnetic ink character data. The output value read by the magnetic reading unit B077 is referred to as an output value read from a document by the magnetic reading unit B077. The data is converted into data or specific code data.
[0034]
The transport speed B071b stores the transport speed at which the document transport type image reading device transports the document, and defines the rotational drive speed of the transport rollers constituting the document transport unit B074. For example, by specifying a reading / transporting speed that matches the image reading without reading magnetic ink character data and a reading / conveying speed that matches the reading of magnetic ink character data by increasing the speed, reading that matches the application can be performed. make it happen.
[0035]
Based on the flowchart shown in FIG. 20, a control procedure for executing reading accompanied by magnetic ink character data reading will be described. The reference numerals used in the description of the content of each step showing the control procedure are based on the block diagram shown in FIG.
[0036]
In step S701, the operator places the document to be read on the document supply unit B073 of the image reading device B070. When placing the original, as described above with reference to FIG. 18, the original is arranged along the fixed-side original guide 71b (see FIG. 18 described above), and the movable-side original guide 71a (see FIG. 18). 18) to adjust the position of the original supply.
[0037]
As described above, the orientation of the original to be read is regulated along the fixed-side original guide 71b (see FIG. 18 described above) so that the magnetic ink character string 2 ( The above-mentioned FIG. 18) can be arranged at the position to be read by the magnetic reading unit 74 (see FIG. 18) constituting the magnetic reading unit B077.
[0038]
In step S702, a reading mode is set. In this case, since a reading mode in which reading accompanied by magnetic ink character data reading is performed is selected, the reading / transporting speed of the original is set to the high-speed mode, and sufficient definition of optical reading cannot always be guaranteed.
[0039]
In step S703, the document is started to be conveyed, and the document conveyance unit B074, which has received the document from the document supply unit B073, scans the document by an image reading line 73 (see FIG. 18) by the conveyance rollers 72a (see FIG. 18 described above). 18).
[0040]
In step S704, the image reading unit B076 optically reads the document on the image reading line 73 (see FIG. 18 described above), and the document transport unit B074 drives the document by the transport roller 72b (see FIG. 18 described above). The original is transported to a magnetic reading unit 74 (see FIG. 18 described above).
[0041]
In step S705, the magnetic reading unit B077 magnetically reads the magnetic ink character string 2 (see FIG. 18 described above) written on the document in the magnetic reading unit 74 (see FIG. 18 described above).
[0042]
In step S706, the document transport unit B074 discharges the document that has been subjected to the optical reading and the magnetic reading to the outside of the apparatus.
[0043]
[Problems to be solved by the invention]
As described above, the image reading apparatus provided with the conventional magnetic ink character data reading mechanism has the following problems.
[0044]
As already mentioned, the optimal reading speed for reading images optically and the optimal reading speed for reading magnetic ink characters magnetically are different.
[0045]
Therefore, for example, in an image reading apparatus which is a document conveying type image reading apparatus and includes a magnetic ink character data reading mechanism, the document conveying speed is in a speed range for magnetically reading the magnetic ink characters, and the image is optically read. The speed value is set to be readable.
[0046]
The document conveying speed value set according to the above conditions does not necessarily coincide with the optimal reading speed for optically reading an image, and also coincides with the optimal reading speed for magnetically reading magnetic ink characters. Not even a thing.
[0047]
Further, the magnetic read head that magnetically reads data using the magnetic ink characters has a configuration including an excitation mechanism and a reading mechanism, and thus usually has a reading directionality.
[0048]
Therefore, since the direction of the magnetic reading head must match the direction of the character string formed by the magnetic ink, a mechanism for regulating the conveying attitude of the document is required.
[0049]
In order to realize a mechanism that regulates the conveying posture of the original having the various dimensions described above, it is advantageous to arrange the conveying rollers for conveying the original at the center distribution and place the original at the center thereof. Needless to say, usually, a document guide fixed to one side is arranged to arrange the magnetic reading head at a specific distance from the side of the document, that is, the transport posture of the document based on one side is regulated. By mechanism.
[0050]
Further, for example, if a flat-bed image reading apparatus is provided with a magnetic ink character data reading mechanism, a mechanism for correcting the position and orientation of a document to be placed is required, and it is difficult to realize the mechanism.
[0051]
Accordingly, in the image reading apparatus having the magnetic ink character data reading mechanism and the control method therefor, when the image to be read is optically read, the image is read at the optimum reading speed. When magnetically reading the magnetic ink character data portion, the image is read at the optimum reading speed by the magnetic reading head set in the optimum reading direction, and the magnetic ink character data is read without any special operation. It is an object of the present invention to efficiently and accurately read.

[0090]
Thus, the center line of the original 1 regulated by the original guides 11a and 11b is always at a fixed position and coincides with the center line of the transport system regardless of the width of the supplied original. Therefore, the original transport type image reading apparatus always receives the originals at the center distribution with respect to the center line of the transport system.
