BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrier media aligning device for aligning a carrier medium such as a magnetic card, a slip, or a passbook to one side surface of a medium carrier guide.

[0002]

2. Description of the Related Art For example, when a magnetic card provided with a magnetic stripe is carried and a magnetic head scans the magnetic stripe at a predetermined position to read or write data, the positioning of the magnetic stripe and the magnetic head is accurate. Must do well.

For this reason, in the conventional width adjusting device, a width adjusting mechanism A as shown in FIG. 6 is provided in the middle of the medium conveyance guide 1 and the width adjusting solenoid 2 is set in an excited state, so that one end of the lever 3 is moved. A pair of width-shifting arms 6a, 6 having a base end rotatably provided at the other end of the lever 3 via an arm holder 4 and friction bodies 5a, 5b at the ends.
In b, after the conveyance medium 7 conveyed in the medium conveyance guide 1 is nipped and width-shifted to one side surface of the medium conveyance guide 1 (width-shifting operation), the magnetic head moves over the magnetic stripe of the magnetic card. I am trying to scan.

Specifically, in this conventional apparatus, when the width-shifting solenoid 2 is in a non-operating state, the arm spring 4 is biased toward the inside of the side surface of the medium conveyance guide 1 by the return spring 12, and each width-shifting arm is moved. Rollers 9a, 9b provided in the middle of 6a, 6b are located at the inclined portions of the guide portions 11a, 11b of the width-adjusting cam 11 attached to the side plate 13, and are provided in the middle of the width-adjusting arms 6a, 6b. The width-shifting arms 6a and 6b against the biasing force of the spring 8
The tip of the is open.

In this state, the transport medium 7 is transported in the medium transport guide 1, and when the transport medium 7 reaches the installation position of the width-shifting device A, the transport is stopped. Then, the width-shifting solenoid 2 operates. As a result, the arm holder 4 moves toward the outside of the side surface of the medium transport guide 1, and the width-shifting arms 6a and 6b also move in the same direction. In this way, the rollers 9a and 9b move the width-shifting cam 1
The guide members 11a and 11b of FIG. 1 are located in parallel with each other, and the tip ends of the width-shifting arms 6a and 6b are closed, and the conveying medium 7 is moved by the friction bodies 5a and 5b of the width-shifting arms 6a and 6b. It is pinched. The arm holder 4 further moves to the outside of the side surface of the medium carrying guide 1, and the carrying medium 7 is moved to one side surface of the medium carrying guide 1.

After that, the width-shifting solenoid 2 becomes inoperative. As a result, the arm holder 4 is urged by the return spring 12 toward the inside of the side surface of the medium conveyance guide 1, and the rollers 9a and 9b of the width-shifting arms 6a and 6b move along the guide portions 11a and 11b of the width-shifting cam 11. Then, it goes up the inclined portion, whereby the tip end portions of the width-shifting arms 6a and 6b are opened.

After carrying out the width-adjusting operation of the carrier medium 7 only once in this manner, for example, reading and writing of a magnetic stripe or the like provided on a magnetic card as the carrier medium 7 is performed.

[0008]

However, in such a conveying medium width adjusting device, when the conveying medium 7 reaches the installation position of the width adjusting mechanism A, the width adjusting arms 6a and 6a are provided.
Since the width adjustment operation by driving b is performed only once, there are cases where sufficient width adjustment is not performed.

Specifically, for example, when the conveyance medium 7 is sucked in a state in which the conveyance medium 7 is separated from one side surface of the medium conveyance guide 1 so much that it exceeds the amount that can be width-adjusted in one movement operation,
In addition, even if the width-shifting arms 6a and 6b are separated from each other once, the width-shifting arms 6a and 6b may be urged to collide with one side surface of the medium conveyance guide 1 and may be slanted by the reaction.

In such a case, the magnetic stripe of the carrier medium 7 such as a magnetic card or passbook is displaced from the reading position or the writing position of the reading head or the writing head, and accurate reading or writing is performed accurately. There was a problem that I could not do it.

Therefore, the present invention intends to provide an apparatus for aligning a carrier medium which can accurately and sufficiently align the carrier medium, and thus can accurately read and write a magnetic stripe or the like of the carrier medium. It is what

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is applied to a medium carrying section of a business processing apparatus for carrying out a desired business process such as printing on a carrier medium such as a magnetic card or passbook having a magnetic stripe or a carrier medium not having a magnetic stripe. Embodiments will be described with reference to the drawings. The same parts as those in FIG. 5 are designated by the same reference numerals and detailed description thereof will be omitted.

FIG. 1 is a diagram showing a part of the structure of the medium carrying section of this embodiment, and 21 is a medium carrying guide. In the middle of the medium carrying guide 21, when the rear end of the carrying medium 22 is carried to the width-shift position D (when the carrying medium is a magnetic card) set at one end of the medium carrying guide 21, A width-shifting mechanism A for performing the width-shifting operation of the transport medium 22, and a plurality of transport rollers 23 for transporting the transport medium 22 in the transport direction indicated by the solid arrow in FIG. .

A pinch roller (not shown) for sandwiching the transport medium 22 is provided in the medium transport section so as to face the transport rollers 23. The pinch roller moves in the direction in which the transport medium 22 is opened by setting the clamp solenoid in the non-excited state, and moves in the direction in which the transport medium 22 is sandwiched by setting the clamp solenoid in the excited state. .

A medium position sensor 24 for detecting the rear end of the conveyed medium 22 is arranged in the middle of the medium conveying guide 21 on the upstream side of the width-shifting position D. Carrier medium 22
When the rear end of the conveying medium 22 is detected by the medium position sensor 24, the medium is conveyed from that position until the rear end of the conveying medium 22 reaches the width-shifting position D.

Further, one side surface 21a of the medium transport guide 21
On the side, a skew sensor 2 as a transport medium skew detection unit that detects that the transport medium 22 is skewed with respect to the one side surface 21a of the medium transport guide 21 near the width-shifting device A.
5 are provided.

The skew sensor 25 is arranged so as not to detect (turn on) skew when the skew of the transport medium 22 is extremely small. This is because when the skew feeding sensor 25 is arranged at a strict position so that even a slight skew of the transport medium 22 can be detected, the transport medium 22 is not skewed even if the width adjusting operation is performed a plurality of times. This is because it becomes difficult and the number of times the carrier medium 22 is ejected and reinserted increases.

The skew sensor 25 is turned on when the transport medium 22 is not skewed with respect to the one side surface 21a of the medium transport guide 21, and is turned off when the transport medium 22 is skewed. It is supposed to be.

A magnetic stripe reading unit 26 for reading the magnetic stripe 22a of the carrying medium 22 is disposed in the middle of the medium carrying guide 21 so as to face the width-shifting device A.

The magnetic stripe reading unit 26 is capable of scanning the magnetic head groove 26a provided along one side surface 21a of the medium carrying guide 21 and the magnetic stripe 22a of the carrying medium 22 along the magnetic head groove 26a. The magnetic head 26b is provided.

The magnetic head 26b is for reading the magnetic stripe 22a, and normally stands by below the medium conveyance guide 21. When the magnetic stripe 22a is read, the magnetic head 26b
The magnetic stripe 22a is moved upward from the standby position and travel-scanned on the magnetic stripe 22a from the position B to the position C along the read line 26c shown by the one-dot chain line in FIG.

Therefore, the magnetic head 26b is used for the carrier medium 2
If the second magnetic stripe 22a is located on the read line 26c, the magnetic stripe 22a can be accurately read.

Although the magnetic head 26a reads the magnetic stripe 22a in the present embodiment, it may write the magnetic stripe 22a.

FIG. 2 is a block diagram showing a schematic configuration of the medium carrying section shown in FIG. 1, and 31 is a carrying control section for drivingly controlling the medium carrying section. The conveyance control unit 31 includes an MPU that constitutes the main body thereof and a memory that stores the number of times of width adjustment by the width adjustment mechanism A counted by the MPU.

The transport controller 31 includes a transport motor 32 for driving the end sensor 24, the skew sensor 25, the transport roller 23, ..., A transport drive circuit 34 for driving the clamp solenoid 33 of the pinch roller, and the width. A width-shifting mechanism drive circuit 35 for driving the width-shifting mechanism A by operating the shift solenoid 2 and a magnetic head driving circuit 36 for driving the magnetic head 26b are connected to each other.

When carrying the carrying medium 22 or reading the magnetic stripe 22a, the carrying control section 31 carries out a control operation as shown in FIG. That is, first in ST1, it is determined whether or not the transport medium 22 having the magnetic stripe 22a is transported.

At this time, when it is judged that the transport medium 22 having the magnetic stripe 22a is transported, the transport medium 22 is transported, and the end sensor 24 detects the end portion of the transport medium 22 and then the predetermined amount is reached. If you transport only
The end portion of reaches the width-shifting position D.

In this state, it is determined in ST2 whether or not the skew sensor 25 is on, that is, whether or not the transport medium 22 is skewed.

When it is determined that the skew sensor 25 is off, that is, when the transport medium 22 is skewed, the width adjusting mechanism A stored in the memory of the transport control unit 31 in ST3. It is determined whether or not the number of times of performing the width adjustment operation by is less than or equal to a predetermined number. The predetermined number of times is set to, for example, several times in consideration of throughput. In the present embodiment, this predetermined number of times is set to 5.

When it is judged in ST3 that the number of times of performing the width-shifting operation is 5 times or less, the width-shifting operation is performed by driving the width-shifting mechanism A by de-energizing the width-shifting solenoid 2 in ST4. It is executed only once (width adjustment control means), the width adjustment number n is incremented, and the number is stored in the memory. Then, the process returns to ST2.

If it is determined in ST3 that the number of width-shifting operations has been executed more than five times, error processing is performed in ST5. That is, for example, an error process is performed such that the transport motor 32 is rotated in the reverse direction to eject the transport medium 22, and the insertion is prompted again.

On the other hand, if it is determined in ST2 that the skew sensor 25 is ON, that is, if the transport medium 22 is not skewed, in ST6 the width-shifting solenoid 2 is moved.
Is brought into a non-excited state and the width-shifting mechanism A is driven to perform the width-shifting operation once (width-shifting control means).
In ST7, whether or not the skew sensor 25 is turned on is determined again as a confirmation means for performing more accurate width adjustment.

If it is determined that the skew sensor 25 is on, the transport control operation is ended, and if it is determined that the skew sensor 25 is off, the step ST5 is performed at ST5.
Perform the same error handling as.

On the other hand, in ST1, the magnetic stripe 2
When it is determined that the transport medium 22 having no 2a is transported, it is determined at ST9 whether the skew sensor 25 is on, that is, whether the transport medium 22 is not skewed.

When it is determined that the skew sensor 25 is on, that is, when the transport medium 22 is not skewed, the transport control operation is ended. At this time, the width adjusting mechanism A does not perform the width adjusting operation.

Further, when it is determined that the skew feeding sensor 25 is off, that is, when the transport medium 22 is skewed, the width shifting operation by the width shifting mechanism A stored in the memory in ST10 is performed. It is determined whether the number of executions is 5 times or less.

At this time, if it is judged that the number of times is 5 times or less, the width-shifting solenoid 2 is de-energized in ST11 and the width-shifting mechanism A is driven to execute the width-shifting operation only once. The width adjustment number n is incremented and the number is stored in the memory. And S
Return to the processing of T9.

When it is determined in ST10 that the number of width-shifting operations is executed more than five times, the same error processing as in ST5 is performed in ST11.

In this embodiment having such a structure, when carrying out business processing such as reading or printing of the magnetic stripe 22a with respect to the carrier medium 22 having the magnetic stripe 22a such as a magnetic card or a passbook, Carrier medium 22
When the sheet is inserted from the insertion port of the business processing apparatus, the conveyance medium 22 is conveyed along the medium conveyance guide 21 while being sandwiched between the conveyance roller and the pinch roller.

Then, the end sensor 24 detects that the carrier medium 2
When the trailing edge of 2 is detected, the sheet is conveyed by a predetermined amount and the conveyance is stopped. As a result, the end of the transport medium 22 reaches the width-shifting position D of the medium transport guide 21.

At this time, for example, when the transport medium 22 is largely skewed with respect to the one side surface 21a of the medium transport guide 21 as shown in FIG. 4, the skew sensor 25 is turned off and the width adjusting mechanism A is turned on. Is driven, and the widthwise movement operation of the transport medium 22 is performed once.

As a result, the carrying medium 22 is moved to the side surface 21a of the medium carrying guide 21. The width-shifting operation by the width-shifting mechanism A is performed up to five times until the skew sensor 25 is turned on, that is, until the skew of the transport medium 22 is no longer detected.

After the skew feeding sensor 25 is turned on, the width adjusting mechanism A performs the width adjusting operation of the conveying medium 22 only once again.

As a result, for example, as shown in FIG. 5, even when the skew sensor 25 is turned on, the carrier medium 22 is slightly skewed, so that the magnetic stripe 22a is slightly displaced from the read line 26c. Are also squeezed,
The magnetic stripe 22a of the carrier medium 22 is the read line 2
Accurately positioned on 6c.

When the skew sensor 25 is turned on by the first skew detection by the skew sensor 25, the width adjusting mechanism A performs the width adjusting operation of the conveying medium 22 only once. Thus, even when the skew sensor 25 is turned on as described above, even when the transport medium 22 is slightly skewed,
The magnetic stripe 22a of the carrier medium 22 is the read line 2
Accurately positioned on 6c.

In this state, the magnetic head 26b is moved and scanned on the magnetic stripe 22a, and the information on the magnetic stripe 22a is read. After that, for example, the transport medium 22 is further transported in the transport direction, and desired printing is performed at a predetermined printing position based on the information from the magnetic stripe 22a.

When carrying out business processing such as printing on the carrier medium 22 having no magnetic stripe, when such carrier medium 22 is inserted from the insertion port of the job processor, the carrier medium 22 is carried. The sheet is conveyed along the medium conveyance guide 21 while being sandwiched between the roller and the pinch roller.

As in the case of the transport medium 22 having the magnetic stripe, when the end sensor 24 detects the rear end of the transport medium 22, the transport is stopped by a predetermined amount and the transport is stopped. As a result, the rear end of the transport medium 22 reaches the width-shifting position D of the medium transport guide 21.

At this time, if the skew sensor 25 is on, for example, the transport medium 22 is further transported in the transport direction,
Desired printing is performed at a predetermined printing position. In this case, unlike the case of the transport medium 22 having the magnetic stripe, even if the transport medium 22 is slightly skewed as shown in FIG. The width adjustment operation of the transport medium 22 by the mechanism A is not performed.

On the other hand, when the skew sensor 25 is turned off by the first skew detection by the skew sensor 25, as in the case of the transport medium 22 having the magnetic stripe,
The width-shifting operation by the width-shifting mechanism A is performed by the skew sensor 25.
Is turned on, that is, until the skew of the transport medium 22 is no longer detected, the process is performed up to 5 times.

However, in this case, unlike the case of the carrier medium 22 having the magnetic stripe, the skew sensor 25 is used.
After turning on, the width adjusting mechanism A does not perform the width adjusting operation of the transport medium 22.

As described above, one side surface 21 of the transport guide 21
The skew sensor 25 is provided near the width-shifting device A on the a side,
When the skew feeding sensor 25 detects the skew feeding of the transport medium 22, the width shifting mechanism A performs the width shifting operation up to five times until the skew feeding sensor 25 does not detect the skew feeding of the transport medium 22. Even when the width of the transport medium 22 cannot be sufficiently adjusted by the one-time width-adjusting operation as in the related art, the width-adjusting can be sufficiently performed.

As a result, especially in the carrier medium 22 having the magnetic stripe 22a, the magnetic stripe 2
2a is a reading line 26c of the magnetic stripe reading unit 26
Can be positioned on top. Further, even if the carrier medium 22 does not have the magnetic stripe 22a, when printing is performed thereafter, accurate printing can be performed from a desired print start position.

Further, when carrying out business processing such as reading or printing of the magnetic stripe 22a with respect to the carrier medium 22 having the magnetic stripe 22a such as a magnetic card or passbook, the width-adjusting mechanism A moves the width of the carrier medium 22. When the skew feeding of the conveyance medium 22 is not detected by the skew feeding detection by the skew feeding sensor 25 after the operation, or the first skew feeding sensor 25
Even if the skew feeding of the transport medium 22 is not detected by the skew feeding detection by, the transport medium 2 by the width adjusting mechanism A only once.
In order to perform the width-shifting operation of 2, for example, as shown in FIG.
It is also possible to correct skew of the transport medium 22 that is not detected by the skew sensor 25.

As a result, the magnetic stripe 22a of the carrier medium 22 is changed to the reading line 2 of the magnetic stripe reading unit 26.
Positioning can be performed more accurately on 6c. Therefore, the carrier medium 2 which requires a relatively high reading accuracy
It is possible to accurately read the second magnetic stripe 22a. Further, even if the position of the skew sensor 25 is not made strict, a sufficient width-shifting operation can be performed, and therefore, the discharge of the transport medium 22 due to an insertion error can be reduced as compared with the conventional case.

Further, when performing a business process such as printing on the carrier medium 22 having no magnetic stripe 22a,
When the skew feeding sensor 25 does not detect the skew feeding of the transport medium 22, the width shifting mechanism A does not perform the width shifting operation of the transport medium 22, so that the throughput of the entire apparatus can be improved.

Even if the skew feeding sensor 25 detects the skew feeding of the conveying medium 22, the width shifting operation by the detection width shifting mechanism A is limited to a predetermined number of times (five times in this embodiment).
The throughput of the entire device can be improved.

In the present embodiment, the business medium 22 having the magnetic stripe 22a is processed. However, the present invention is not limited to this, and the business medium 22 having a bar code is used. Processing may be performed. In this case, an optical reading system for reading a bar code may be provided instead of the magnetic head 26b for reading the magnetic stripe.

[0061]

As described in detail above, according to the present invention, the width of the carrier medium can be sufficiently adjusted, and therefore, the reading and writing of the magnetic stripe of the carrier medium can be accurately performed. In particular, it is possible to provide a conveyance medium width adjusting device that can perform width adjustment of a conveyance medium that is skewed to the extent that it cannot be read by a skew sensor.
