Next, as shown in FIG. 4 (e), the slip 60 is retracted or discharged until the passbook 56 can be transported.

 Next, as shown in FIG. 4 (f), the passbook 56 is discharged.

When the same processing is continuously performed a plurality of times, the above-described operations in FIGS. 4A to 4E are repeated. In this case, usually, the slip 60 is replaced with another slip 60 each time. However, as for the passbook 56, the passbook 56, which is the same medium, moves plural times between the printing position and the retreat position without being continuously discharged. Will be.

Before the MS read in FIG. 4 (b), the medium (here, passbook 56) is always aligned (positioning the passbook to perform the MS read at the correct position).
When the same process is executed continuously multiple times, the second and subsequent times
In many cases, the MS read operation is not performed, so that the medium (here, the passbook 56) is skewed. Note that the width of the medium (passbook 56) is always adjusted even before writing to MS58 (referred to as MS write).

Next, FIG. 3 is used for setting the passbook 56 (FIG. 4 (a)), inhaling operation (FIG. 4 (b)), reading the MS 58 (FIG. 4 (b)), and adjusting the width before writing. Will be described in more detail. FIG. 3 is a simplified plan view showing an example of the passbook transport path 61a in the passbook slip printer.

In FIG. 4A, the passbook 56 is set by being pressed in parallel to the medium reference guide 57 by the medium width shifting mechanism 53. A medium skew detection sensor 54 is provided at the position of the passbook transport path 61a near the medium reference guide 57, and when this sensor 54 detects the presence of a medium, the medium provided at the front and back of the set passbook 56 is provided. The clamp roller 52 operates, and the medium clamp roller 52 clamps the passbook 56.

Next, in FIG. 4 (b), when the passbook 56 is inhaled, by rotating the transport roller 62 facing the medium clamp roller 52 and provided in the medium transport path 61, particularly the passbook transport path 61a, The passbook 56 is carried inside. This transport roller 62
Is connected to the transport motor 51, and the transport roller 62 rotates as the transport motor 51 rotates. The medium clamp roller 52 and the transport motor 51 are provided by the microprocessor 1

Next, at the time of reading and writing operation of the MS 58 affixed to the back cover of the passbook 56, in order to satisfy the function and performance of the MS 58, the MS 58
It is necessary to reduce the skew of the bankbook 56.

Therefore, before reading (FIG. 4 (b)) and writing operations of the MS 58, the microprocessor 1 operates the medium width approaching mechanism 53 to press the passbook 56 with MS against the medium reference guide 57. Although there are various types of the medium width shifting mechanism 53, they are omitted here.

Here, the write operation of the MS 58 is performed in the following cases when the operations of FIGS. 4A to 4E are continuously repeated a plurality of times. That is, in the case of such a continuous process, the writing of the MS 58 is usually performed at the last time, for example, after FIG. 4 (e).

(Problems to be Solved by the Invention) However, in the above-described conventional passbook slip printer, in the case of a continuous process in which the operations of FIGS. 56), the suction and evacuation (FIGS. 4 (b) and (c)) are repeated several times,
The skew of the medium (passbook 56) increases sequentially.

At the time of media width adjustment by the media width adjustment mechanism 53 before the writing operation of the MS 58 in the final round, the medium (passbook) has already been set.
Since the skew amount of 56) has become too large, the medium (passbook 56) is moved by the medium width shifting mechanism 53 to the medium reference guide 57.
Takes a long time to correct the skew of the medium pressed against the medium. Further, depending on the method of the medium width shifting mechanism 53, the skew of the medium (passbook 56) cannot be completely corrected, and the MS writing bend may occur. Further, in the printing operation (FIG. 4B) on the medium (passbook 56) in the middle of the continuous processing, there is a problem that the printing is bent.

SUMMARY OF THE INVENTION It is an object of the present invention to easily (in a short time) correct skew of a medium with an MS on a medium that performs continuous processing on the medium by repeating suction and retraction of the input medium.

It is possible to prevent an MS writing bend in a medium with an MS and a print bend in a medium having a certain thickness or more (including a medium with an MS).

(Example) Next, an example of the present invention will be described with reference to the drawings.

(I). FIG. 1 is a block diagram showing a first embodiment of a passbook slip printer according to the present invention. In this figure, the same or corresponding parts as those in FIG.

In FIG. 1, reference numeral 6 denotes MS as storage means of the present invention.
The MS flag memory 6, which is a flag memory, is connected to the microprocessor 1 via the bus 4.
The microprocessor 1 sets “1” to the MS flag memory 6 when the MS passbook 56 is read by the MS head 55, that is, when the MS of the MS passbook 56 has been read (MS flag is set). On).

Reference numeral 7 denotes a program memory connected to the microprocessor 1 via the bus 4. The program memory 7 stores various programs for operating the passbook slip printer shown in FIG. 1, and the microprocessor 1 operates according to the program contents of the program memory 7.

The microprocessor 1 and the program memory 7 constitute control means of the present invention. Further, the medium skew detection sensor 54 constitutes the skew detecting means of the present invention, and the medium width shifting mechanism 53 constitutes the skew correcting means of the present invention.

A passbook transport path in the passbook slip printer shown in FIG.
The plan view of 61a is the same as that of FIG.

The basic movement of the medium in the passbook slip printer shown in FIG. 1 is the same as that shown in FIG. 4 described above, and therefore the differences will be described below.

4 (a) to 4 (e) with respect to the entered passbook 56 with MS.
Is repeated multiple times to perform continuous processing,
The features of the present invention will be described with reference to FIGS. Other points are the same as the conventional one.

At the stage of the first processing shown in FIG. 4B, the passbook 56 with MS is sucked and conveyed on the medium conveying path 61 to below the print head 59. During the transfer, the MS head 55 is brought into contact with the MS 58 affixed to the back cover of the passbook 56 with MS, and the MS lead is executed.

In the present invention, the microprocessor 1 sets an MS flag in the MS flag memory 6 by the MS read (MS flag).
Set a flag "1" indicating that the read operation has been completed (MS flag on). It is to be noted that printing using the print head 59 on the passbook 56 with MS conveyed to below the print head 59 is the same as in the related art.

Each time, in the passbook saving operation of FIG.
The medium skew detection sensor 54 checks whether the skew of the passbook 56 with MS has occurred. Therefore, during the passbook retreat operation, the passbook 56 with MS becomes as shown by the dashed line in FIG. 3 and when the skew of the passbook 56 with MS occurs, the medium skew detection sensor 54 detects that there is no medium and detects the detection signal. (Medium skew detection signal) to the microprocessor 1.

The microprocessor 1 is a sensor for detecting a medium skew.
When there is a detection signal from 54, the MS flag memory 6
When the MS flag “1” is set, that is, when the flag “1” indicating that the MS read has been executed is set in the MS flag memory 6, the medium width shifting mechanism 53 is operated and the MS passbook 56 is operated. Is pressed against the medium reference guide 57 to correct the skew of the passbook 56 with MS.

Therefore, the microprocessor 1 has the MS flag memory 6
When the MS flag “1” is set to “1”, every time the passbook 56 with MS is skewed, the MS
Since the skew correction of the passbook 56 is performed by the medium width shifting mechanism 53, no print curl occurs when printing the MS passbook 56 (FIG. 4B).

Also, usually at the end (for example, after the last time of FIG. 4 (e)), writing of the MS-attached passbook 56 to the MS 58 (MS write) is performed. Mechanism 53
The width of the medium (here, MS passbook 56) is adjusted.
In this case, when the passbook is evacuated (FIG. 4 (c)), if there is a skew of the passbook 56, the skew of the passbook 56 is corrected each time. , Passbook 56
The width of the medium (passbook 56) can be adjusted very easily (in a short time) by the medium width adjustment mechanism 53 before the MS light is applied to the passbook 56. No bending occurs.

The reason why the microprocessor 1 checks whether or not the MS flag “1” is set in the MS flag memory 6 when the medium width adjustment is performed, that is, whether or not the MS read has been performed, is as follows. by.

That is, when the MS read has been performed, the medium is a medium with MS (MS passbook 56), and the medium with MS has a predetermined thickness or more in advance. Therefore, even when the medium width shifting mechanism 53 performs the medium width shifting on the MS-attached medium, the MS-attached medium does not collapse.

On the other hand, in the case of a thin medium (medium having a certain thickness or less) instead of the medium with MS, the medium width shifting mechanism 53
Therefore, when the thin medium is pressed against the medium reference guide 57, the medium becomes weak and crumple. Therefore, in order to perform medium width adjustment only on the MS-attached medium (MS-attached passbook 56), it is checked whether or not the MS read has been performed.

Further, the MS flag "1" of the MS flag memory 6 is cleared by the microprocessor 1 when the passbook is discharged as shown in FIG.

(II). FIG. 5 is a second embodiment of the passbook slip printer according to the present invention.
FIG. 3 is a block diagram showing an embodiment. In FIG.
The same reference numerals are used for the same or corresponding parts as in FIG. 2 and FIG.

In FIG. 5, reference numeral 8 denotes a thickness detection flag memory as storage means of the present invention. The thickness detection flag memory 8 is connected to the microprocessor 1 via the bus 4. Reference numeral 9 denotes a program memory connected to the microprocessor 1 via the bus 4. The program memory 9 stores various programs for operating the passbook slip printer shown in FIG. 5, and the microprocessor 1 operates according to the program contents of the program memory 9.

The microprocessor 1 is connected to an external interface via a peripheral circuit 3. Then, as described above, the microprocessor 1 prints on the medium, for example, the passbook 56 with MS or the slip 60 (see FIG. 4 (b)) and reads the MS58 of the passbook 56 with MS according to the instruction from the external interface. Execute writing and the like.

The microprocessor 1 includes a medium, for example, an MS passbook 56.
Transport motor 51, a medium clamp roller 52 connected to the drive circuit 5, and a skew correcting means of the present invention in order to perform printing on a document or a slip 60 and reading and writing operations of the MS 58 of the MS passbook 56. The medium width shifting mechanism 53, the medium skew detection sensor 54 as the skew detection means of the present invention, the MS head 5
5. It controls the print head 59 and the thickness detecting mechanism 63 as the thickness detecting means of the present invention. Here, the microprocessor 1 and the program memory 9 constitute control means.

As shown in FIG. 6, the thickness detecting mechanism 63
(Especially, provided in the passbook transport path 61a), at the time of inhaling the inserted medium, the thickness of the medium is detected, and it is determined whether or not the thickness is more than a certain thickness. Sends a signal to the thickness detection flag memory 8 to set the thickness detection flag "1" in the thickness detection flag memory 8 (sets the flag "1" indicating that the medium has a certain thickness or more ( The thickness detection flag 63)
If the thickness of the medium is equal to or greater than a certain thickness, a signal to that effect may be sent to the microprocessor 1 and the microprocessor 1 may set the thickness detection flag “1” in the thickness detection flag memory 8.

Next, the passbook transport path in the passbook slip printer shown in FIG.
FIG. 6 shows a simplified plan view of 61a. 6, the same or corresponding parts as those in FIG. 3 are denoted by the same reference numerals. In FIG. 6, the difference from FIG. 3 is the passbook transport path.
That is, the thickness detecting mechanism 63 is provided in 61a. There are various types of the thickness detection mechanism 63.

In FIG. 6, the configuration and operation other than the thickness detection mechanism 63 are the same as those in FIG. 3 described above.

That is, the medium, for example, the passbook 56 is pressed in parallel to the medium reference guide 57 by the medium width shifting mechanism 53 and set as shown by the solid line (the state of FIG. 4A). The medium skew detection sensor 54 is connected to the passbook transport path near the medium reference guide 57.
When the sensor 54 detects the presence of a medium, the medium clamp rollers 52 provided above and behind the set passbook 56 operate, and the medium clamp roller 52 moves the passbook 56. Clamp.

Next, at the stage of FIG. 4 (b), when the passbook 56 is sucked, the transport roller 62 facing the medium clamp roller 52 and provided in the passbook transport path 61a is rotated.
The passbook 56 is carried inside. The transport roller 62 is connected to the transport motor 51, and the transport roller 62 rotates according to the rotation of the transport mode 51. The drive of the medium clamp roller 52 and the transport motor 51 is controlled by the microprocessor 1 via the drive circuit 5.

Next, at the time of reading and writing operations of the MS-attached medium, for example, the MS 58 affixed to the back cover of the MS-attached passbook 56, the functions of the MS 58
It is necessary to reduce the skew of the passbook 56 with MS to satisfy the performance.

Therefore, before reading (FIG. 4 (b)) and writing operations of the MS 58, the microprocessor 1 operates the medium width approaching mechanism 53 to press the passbook 56 with MS against the medium reference guide 57. Note that the write operation of MS58 is described in FIGS. 4 (a) to 4 (e).
In the case of a continuous process in which the above operation is continuously repeated a plurality of times, the process is usually performed at the last time, for example, after FIG. 4 (e).

Next, the basic movement of the medium in the passbook slip printer shown in FIG. 5 is the same as that shown in FIG.

With reference to FIGS. 4 and 6, a description will be given of the features of the present invention in the case where the continuous processing is performed on a medium pressed against the medium reference guide 57 and in a set state, for example, the passbook 56 with MS.

At the time when the medium is sucked in FIG. 4 (b) in the first processing, the thickness detecting mechanism 63 detects the thickness of the medium, and if the thickness of the medium is a predetermined value or more, the thickness detecting flag memory Set the detection flag "1" for the thickness of 8. In this case, MS as the medium
Since it is the passbook 56, the thickness detection flag "1" is set in the thickness detection flag memory 8. The other operations in FIG. 4B are the same as those described in the related art.

In addition, each time, the medium shown in FIG.
In the evacuation operation 56, the medium skew detection sensor 54 checks whether or not the skew of the passbook 56 with MS has occurred. Therefore, during the evacuation operation of the medium, for example, the MS passbook 56, when the MS passbook 56 becomes as shown by the dashed line in FIG. 6 and the skew of the MS passbook 56 occurs, the medium skew detection sensor 54 , The medium is detected, and a detection signal (medium skew detection signal) is sent to the microprocessor 1
Output to

The microprocessor 1 is a sensor for detecting a medium skew.
When the thickness detection flag “1” is set in the thickness detection flag memory 8 when there is a detection signal from 54,
The skew of the passbook 56 with MS is corrected by operating the medium width shifting mechanism 53 and pressing the passbook 56 with MS against the medium reference guide 57.

Here, the microprocessor 1 determines whether or not to operate the medium width shifting mechanism 53 based on whether or not the thickness detection flag “1” is set in the thickness detection flag memory 8. This is for preventing the medium from becoming crumpled when the medium having a small thickness is pressed against the medium reference guide 57 because the medium has a weak stiffness.

The thickness detection flag "1" of the thickness detection flag memory 8 is cleared by the microprocessor 1 when the medium (the passbook 56 with MS) shown in FIG.

As can be seen from the above description, the microprocessor 1
Indicates that the thickness detection flag “1” is stored in the thickness detection flag memory 8.
After that, every time the medium (for example, a medium with MS (MS passbook 56) or a medium having a certain thickness or more) is skewed during the medium retreat operation, the skew occurs. Since the skew correction of the medium is performed by the medium width shifting mechanism 53,
When printing is performed on a medium having a certain thickness or more (including the passbook 56 with MS) (FIG. 4 (b)), no print bending occurs.

In addition, usually, at the end (for example, after the last FIG. 4 (e)), writing (MS write) of the medium with MS (passbook 56 with MS) to MS is performed. The width of the medium with MS is always shifted by the medium width shifting mechanism 53. In this case, when the medium with MS is evacuated (FIG. 4 (c)), if there is any skew of the medium with MS, the skew of the medium with MS is corrected each time. When performing media width adjustment,
The skew of the medium with MS is slight even if it is slight, and the width of the medium with MS can be adjusted very easily (in a short time) by the medium width adjustment mechanism 53 before the MS writing on the medium with MS. There is no MS light bending.

In addition, since the medium width adjustment is not performed on a thin medium without MS, even if the print bending may occur, there is no particular problem. In other words, thin media handled by the printer shown in FIG.

(III). FIG. 7 is a block diagram showing a third embodiment of the passbook slip printer according to the present invention. In the figure,
The same reference numerals are used for the same or corresponding parts as in FIGS. 1, 2, and 5.

In FIG. 7, reference numeral 10 denotes a medium type flag memory as storage means of the present invention. The medium type flag memory 10 is connected to the microprocessor 1 via the bus 4.

The content (thickness information) specified by the medium type 2 (thickness information) 15 in the command 12 from the external interface is stored in the medium type flag memory 10 by the microprocessor 1. Note that the medium type flag memory 10
Directly from outside without using the microprocessor 1
The medium thickness information may be stored.

Reference numeral 11 denotes a program memory connected to the microprocessor 1 via the bus 4. The program memory 11 stores various programs for operating the passbook slip printer shown in FIG. 7, and the microprocessor 1 operates according to the program contents of the program memory 11. Here, the microprocessor 1 and the program memory 11 constitute control means of the present invention.

The microprocessor 1 is connected to an external interface via a peripheral circuit 3. Then, the microprocessor 1 prints on a medium, for example, a passbook 56 with MS or a slip 60 (see FIG. 4 (b)) and reads MS58 of the passbook 56 with MS (MS read) according to an instruction from an external interface. Execute writing (MS write) and the like.

The microprocessor 1 includes a medium, for example, an MS passbook 56.
Transport motor 51, a medium clamp roller 52 connected to the drive circuit 5, and a skew correcting means of the present invention in order to perform printing on a document or a slip 60 and reading and writing operations of the MS 58 of the MS passbook 56. The medium width shifting mechanism 53, the medium skew detection sensor 54 as the skew detection means of the present invention, the MS head 5
5. The print head 59 will be controlled.

Also, the medium transport path in the passbook slip printer shown in FIG.
The plan view of 61 (passbook transport path 61a) is the same as that of FIG.

The basic movement of the medium in the passbook slip printer in FIG. 7 is the same as that in FIG. 4 described above, and a description thereof will be omitted.

Instead of providing the thickness detecting mechanism 63 and the thickness detecting flag memory 8 as in the second embodiment (FIGS. 5 and 6), a medium type flag memory 10 is provided and externally via an external interface. For example, a command 12 shown in FIG. 8 is sent to the microprocessor 1 and the content (thickness information) designated by the medium type 2 (thickness information) 15 in the third byte of the command 12 ) Is stored in the medium type flag memory 10 to obtain the same effect as in the second embodiment.

Here, in the command 12, in the medium of the passbook inhalation command 13, the second byte is a medium type 1 (size information) 14,
The third byte is medium type 2 (thickness information) 15 and the fourth byte is check code 16.

The passbook inhalation command 13 is a command for instructing the inhalation of the medium to be inhaled from the entrance of the passbook transport path 61a of the medium transport path 61. With this command, the microprocessor 1 starts the inhalation of the medium. At this time, the microprocessor 1 checks whether or not the sizes of the media to be sucked match according to the contents specified by the medium type 1 (size information) 14 in the second byte. If the sizes do not match, the microprocessor 1 stops the suction operation of the medium halfway and automatically executes the discharge operation.

Next, the microprocessor 1 stores the content (thickness information) specified by the medium type 2 (thickness information) 15 in the third byte in the medium type flag 10. The check code 16 in the fourth byte is the result data calculated by a certain method based on the data contents of the first to third bytes of the command 12.

The printing apparatus that has received the command 12 also performs an operation on the data contents of the first to third bytes of the command 12 in a similar manner, and checks whether the data matches the check code 16 of the fourth byte. If the result of the check is a mismatch, the microprocessor 1 executes this command 12
Is executed, and an NG response is sent through the external interface.

Next, when the command 12 as shown in FIG. 8 described above is input from the external interface, a medium such as MS
When the passbook 56 is inserted from the entrance of the passbook transport path 61a,
The set state is set as shown in FIG. Now, in the case where a continuous process of continuously repeating the operations of FIGS. 4 (a) to (e) a plurality of times is performed on this MS-attached passbook 56, the features of the present invention will be described with reference to FIGS. This will be described with reference to FIG.

By the passbook inhalation command 13 of the command 12 shown in FIG.
Inhalation of the MS passbook 56 is started. At this time, it is checked whether the passbook 56 with MS matches the size specified in the medium type 1 (size information) 14 of the command 12. And
Here, it is assumed that the sizes match.

In the medium type flag memory 10, designated thickness information is stored based on the medium type 2 (thickness information) 15 of the command 12. It is also assumed that the check code 16 of the command 12 has been correctly checked. Hereinafter, a series of operations shown in FIG. 4 (b) will be executed.

In addition, each time, the medium shown in FIG.
In the evacuation operation 56, the medium skew detection sensor 54 checks whether or not the skew of the passbook 56 with MS has occurred. Therefore, at the time of the evacuation operation of the MS-attached passbook 56, the MS-attached passbook 56 becomes as shown by the one-dot chain line in FIG.
When the skew of 56 occurs, the medium skew detection sensor 54
Detects that there is no medium, and outputs a detection signal (medium skew detection signal) to the microprocessor 1.

The microprocessor 1 is a sensor for detecting a medium skew.
In the case where the detection signal is received from 54, if the content of the medium type flag memory 10 indicates that the thickness is equal to or greater than a certain thickness, the medium width shifting mechanism 53 is operated and the MS
The skew of the MS passbook 56 is corrected by pressing the passbook 56 against the medium reference guide 57.

Here, the microprocessor 1 determines whether or not to operate the medium width adjusting mechanism 53 based on the contents of the medium type flag memory 10 because the medium 1 is pressed against the medium reference guide 57 for a medium having a small thickness. In addition, it is to prevent the medium from becoming crumpled due to the weakness of the medium.

Further, the contents of the medium type flag memory 10 are cleared by the microprocessor 1 when the medium (the passbook 56 with MS) shown in FIG.

It is to be noted that the medium width shifting mechanism 53 performs the medium width shifting before the MS 58 reading / writing operation of the MS-attached medium (MS-attached passbook 56) as described above.

Also in the third embodiment described above, the same effect as in the second embodiment can be obtained.

The present invention is not limited to the present embodiment, and various applications and modifications can be considered without departing from the gist of the present invention.

(Effect of the Invention) As described above, according to the present invention, in the case where continuous processing is performed on a medium by repeating suction and retraction of a charged medium, during the medium retreat operation, the medium with MS and other predetermined thicknesses or more Skew of the medium can be easily corrected, thereby preventing MS writing bending on a medium with MS and printing bending on a medium having a certain thickness or more (including a medium with MS). Also,
Skew correction before MS writing to an MS-attached medium is extremely easy and can be performed in a very short time as compared with the related art.
