[0001]

The present invention relates to a form processing device.

[0002]

2. Description of the Related Art In recent years, a form processing apparatus has been used more and more due to improvements in character recognition technology. For example, for forms such as various slips and application forms used in various fields including banks and government offices, conventionally, a person who processes the forms inputs the contents of the forms to a computer and performs predetermined processing. However, recently, Japanese Patent Application Laid-Open No. 6-107364 and
As disclosed in Japanese Patent Application Laid-Open No. 1-177784, an optical character recognition device, that is, an OCR (Optical) is disclosed.
Characters on a form are read using a character reader (Character Reader), taken into a computer, and the read characters are recognized. Various processes are performed based on the recognized characters.

FIG. 9 is a diagram showing an example of such a form processing apparatus. The form processing device 100 includes a housing 101. A form supply unit 1 for supplying a form T is provided in the housing 101.
10, a transport mechanism 120 for transporting the form T, an information reading unit 130 for reading a record from the form T transported by the transport mechanism 120, a printer unit 140 for printing on the form T, and cooperative control of these. Control computer 1
50 are provided. In addition, H in the drawing indicates a transport path.

The form supply unit 110 is made of a material such as rubber, a hopper 111, a base 112 mounted on the hopper 111, the form 112 being placed thereon, and moving upward as the form T is taken out. Base 112
Take-out rollers 113a, 113b for taking out the upper form T
And a separator 114 for separating the form T.

[0005] The transport mechanism 120 includes a tension roller 121 and a drive roller 122 for transporting the form T at a constant speed, and a stacker 123 for discharging the form T.

The information reading section 130 includes light sources 131a, 131
1b, a reflector 132, a folding mirror 133,
134, lens 135, CCD sensors 136, 13
7 is provided.

[0007] The printer section 140 includes a dot printer head 141, an ink ribbon 142, and a platen 143.

[0008] The form processing apparatus 100 configured as described above.
Then, the form T is read as follows. That is, the form bundle in which the forms T are stacked is placed on the base 112. The form T at the top of the bundle is taken out by the take-out roller 113.
a, 113b are rotated clockwise, the form T
Are taken out one by one. Removal roller 113
When a plurality of forms T are taken out by a and 113b, the separator 114 prevents the second and subsequent forms T from being taken out together with the first form T. The extracted form T is conveyed in the direction of arrow R in the figure, and is conveyed at a constant speed while receiving a conveying force between the tension roller 121 and the drive roller 122.

When the form T reaches the reading section A, reading of information displayed on the surface of the form T is started. The reading method is as follows. Light emitted from the light sources 131a and 131b is condensed on the reading unit A by the reflector 132, and when light is applied to the character of the form T at the position of the reading unit A, the reflected light from the form T The light is returned by the return mirrors 133 and 134, passes through the lens 135, and is imaged by the CCD sensor 136. An optical path from the light sources 131a and 131b to the CCD sensor 136 is defined as an optical path K. The information of the form T read by the CCD sensor 136 is taken into the control computer 150, where the character is recognized and the data is processed.

The above-described series of operations are performed continuously while moving the form T. When reading information on the surface of the form T, a reduction optical system is usually used. When the form T that has passed through the reading unit A reaches the reading unit B, reading of information on the back surface of the form T is started. In the reading section B, a contact type line CCD sensor 137 is used because there is no space for the reduction optical system. When it is not necessary to read the information on the back side of the form T, the contact type line CCD sensor 137 is unnecessary.

The form T that has passed through the reading section B is transported along a transport path H. Form T conveyed by conveyance path H
Is recorded in the printer unit 140 indicating that the information has been read from the form T. That is, predetermined characters such as a reception number or a user-specific number are printed on the form T between the ink ribbon 142 and the platen 143. The printed form T is conveyed in the direction of the arrow and sent to the stacker 150. Form T
Are continuously performed until the sheet T disappears from the base 112, and the read and printed forms T are accumulated in the stacker 150.

[0012]

The form processing apparatus described above has the following problems. In other words, there is no problem when taking out the same type of form T one by one, but when taking out forms T of various sizes, thicknesses and paper qualities different from each other, the forms T may not be aligned in the same direction. Many. this is,
This is because even if the forms are arranged to some extent when placed on the hopper, it is difficult to arrange the forms due to the difference in the coefficient of friction between the forms when the forms having different sizes and types are stacked.

Therefore, there is a case where the skewed forms T (the directions of which are shifted from the normal conveyance direction) are taken out one by one from the stacked state. At this time, the conventional apparatus has no means for performing skew correction, and there is a possibility that character recognition cannot be performed in the case of a form T having a large skew amount.

Accordingly, an object of the present invention is to provide a form processing apparatus capable of reliably performing skew correction with a simple mechanism even when forms T having different sizes, thicknesses, and paper qualities are mixed. And

The transport mechanism 20 includes a tension roller 21 and a drive roller 2 that transport the form T at a constant speed.
2 and a stacker 23 for discharging the form T.

The information reading section 30 includes light sources 31a and 31b.
, A reflector 32, folding mirrors 33 and 34,
A lens 35 and CCD sensors 36 and 37 are provided. In FIG. 1, A and B indicate reading positions.

The printer section 40 includes a dot printer head 41, an ink ribbon 42, and a platen 43.

A plurality of correction devices 60 are provided along the depth direction of the form T, and a plurality of sets of position sensors 61 and 62 for detecting the position of the form T to measure the skew amount or skew angle of the form T. , A conveyor belt 63, and a plurality of vibrating brushes 64 disposed opposite to the conveyor belt 63.
And a side wall 65.

The position sensors 61 and 62 include a light emitting unit 61a and a light receiving unit 61b, a light emitting unit 62a and a light receiving unit 62, respectively.
b. The position sensor 61 has a form T on the optical path.
When there is no form, light can be detected by the light receiving unit 61b, and when there is a form T, it cannot be detected, and the position of the form T is detected. The skew amount of the skew-corrected form T can be similarly confirmed by the position sensor 62.

The vibrating brush 64 has a drive voltage of CD5
A vibration motor 64a capable of obtaining a rotation speed of about 5,000 rpm to 7,000 rpm at about (V), and a brush 64 made of, for example, nylon as a main component and capable of removing static electricity;
b.

In the form processing apparatus 1 configured as described above, the form T is read as follows. That is, the form bundle in which the forms T are stacked is placed on the base 12. The form T at the top of the bundle is the take-out rollers 13a, 1
By rotating clockwise 3b, the forms T are taken out one by one and supplied onto the conveyor belt 63. In addition,
When a plurality of forms T are taken out by the take-out rollers 13a and 13b, the separation pad 14 prevents the second and subsequent forms T from being taken out together with the first form T.

In the correcting device 60, the skew amount is measured by the position sensor 61, and when the skew amount is a skew amount that does not hinder the predetermined reading, the skew amount is directly conveyed in the reading position A direction. If the skew amount is larger than the predetermined amount, the form T
The skew correction is performed by the vibrating brush 64 on the transport belt 63.

The form T sent to the conveyor belt 63 measures the amount of skew detected when the leading end of the form passes through the position sensor 61. If the skew amount is larger than a predetermined skew amount, the vibrating brush 64 moves the form T By oscillating in the direction perpendicular to the transport direction, skew correction is performed by repeatedly contacting and separating the surface of the form T. The timing at which the vibrating brush 64 is operated is determined by the position sensor 6
When the number reaches 2, the trailing end of the form is still the take-out roller 13

After that, the oscillating brush 64 is operated, and the skew correction is completed before the leading end of the form T enters the transport mechanism 20.

At the time of skew correction, the form T can be skew-corrected so that the corner of the form T first hits the side wall 65, and then the form T follows the side wall so that the form T is parallel to the transport direction. Therefore, skew correction can be similarly performed on the forms T oriented in various directions.

Although three sets of position sensors 61 and 62 are installed here, the size of the form T to be handled is, for example, from A8 to A3, and in order to measure the skew amount with high accuracy. This is because it is better to use two sets according to the size of each form.
For this reason, three sets are used here, but any number of sets may be provided as long as a plurality of sets are provided.

The form T whose skew has been corrected is conveyed in the direction of arrow R in the figure, and is conveyed at a constant speed while receiving a conveying force between the tension roller 21 and the drive roller 22.

When the form T reaches the reading position A, the form T
Start reading the information displayed on the surface. The reading method is such that the light emitted from the light sources 31a and 31b is condensed on the reading position A by the reflector 32, and when the light of the form T at the position of the reading position A is irradiated with the light, the reflected light from the form T The light is returned by the return mirrors 33 and 34, passes through the lens 35, and is imaged by the CCD sensor 36. Light source 31
An optical path from a, 31b to the CCD sensor 36 is defined as an optical path K. The information of the form T read by the CCD sensor 36 is taken into the control computer 50, where the character is recognized and the data is processed.

The above-described series of operations are performed continuously while moving the form T. When reading information on the surface of the form T, a reduction optical system is usually used. When the form T that has passed the reading position A reaches the reading position B, reading of information on the back side of the form T is started. At the reading position B, a contact type line CCD sensor 37 is used because there is no space for the reduction optical system. When it is not necessary to read the information on the back side of the form T, the contact type line CCD sensor 37 is unnecessary.

The form T that has passed the reading position B is
Conveyed along. In the form T conveyed by the conveyance path H, a mark indicating that information has been read from the form T is recorded in the printer unit 40. That is, predetermined characters such as a reception number or a user-specific number are printed on the form T between the ink ribbon 42 and the platen 43. The printed form T is conveyed in the direction of the arrow and sent to the stacker 23. Such an operation is continuously performed until the form T disappears from the base 12 and read,
The form T for which printing has been completed is accumulated in the stacker 23.

When the skew is taken out as shown in FIG. 6, the position sensor 81 first measures the skew amount. In this case, since the front side wall is taken out with a delay, the skew is increased by making the transport speed V2 of the second transport belt 84 faster than the transport speed V1 of the first transport belt 83 by an amount corresponding to the skew amount. Correction becomes possible. It is desirable that the speed difference between the conveyor belts 83 and 84 be made after the rear end of the form T has passed the position sensor 81. After the position sensor 82 determines whether the skew has been corrected, the skew is sent to the reading position A by the tension roller 21 and the drive roller 22.
