It may be a direction. In addition, the first
The surface printing step and the second surface printing step are desirably performed simultaneously or in parallel.

According to this method, for example, after reading magnetic information from a recording medium for personal check,
By simultaneously performing front and back printing and back printing while transporting in the discharge direction, all processing can be performed only by loading and operating the recording medium once in the device, greatly reducing the processing time. The operation performed by the operator is also simplified. Also, since the magnetic information is read while the recording medium is once conveyed in the discharge direction and then conveyed to the insertion side, even if the recording medium pops out of the discharge port during magnetic reading, the amount of protrusion during reading the magnetic information is As a result, since the operator does not hinder the conveyance of the recording medium on the discharge port side, the reading accuracy of the magnetic information is improved.

In the above case, the second-side printing step is performed prior to the first-side printing step, and the conveying direction of the recording medium in the reading step is the first direction, and The transport direction of the recording medium in the one-side printing step is the first direction, and the transport direction of the recording medium in the second-side printing step is the second direction.
Direction. According to this method, after reading the magnetic information from the recording medium, the magnetic information is conveyed in a discharge direction to a predetermined position, and then the endurance printing is performed by the second print head while being conveyed in a direction opposite to the discharge direction. After that, the printing medium is transported to a predetermined position in the direction opposite to the discharging direction and then printed while being transported in the discharging direction again, so that all the processing can be performed by simply loading and operating the recording medium once in the apparatus. This can greatly reduce the processing time and simplify the operation performed by the operator.
Further, since the first print head and the second print head do not print at the same time, the peak current used can be reduced, and the elements constituting the power supply and the circuit can be reduced in cost and further reduced. .

Further, in the above case, the method further comprises a step of discharging the recording medium if the reading is unsuccessful, based on a result of the reading in the reading step. It is desirable that the printing be performed prior to the one-side printing step and the second-side printing step. In addition, it is preferable that a transport direction of the recording medium in the unsuccessful ejection step is the second direction. Thus, the discharge direction at the time of abnormality can be made different from the discharge direction at the time of normal, so that the operator can easily determine the abnormality.

The first transport roller 2 is located on the paper transport path.
Form stoppers 31 are provided between the rollers 7 and 28 and the second transport rollers 29 and 30. The form stopper 31 is for temporarily stopping the inserted check paper S, and is configured to be able to retreat from the transport path at a predetermined timing.

In the vicinity of the foam stopper 31,
A check sheet sensor 32 for detecting the presence or absence of the check sheet S is provided. As the check paper sensor 32, for example, a transmission type or reflection type photo sensor or the like is used.

On the other hand, a magnetic head 33 as an information reading head for reading MICR characters recorded on the check paper S is provided near the first transport rollers 27 and 28. The magnetic head 33 includes a pressing member (not shown) for pressing the check paper S against the magnetic head 33 when reading processing is performed so that the check paper S adheres to the head portion. As the pressing member, a known member such as a roller or a pad having a low friction coefficient can be used. Further, the pressing of the check paper S by the pressing member can be released, and a well-known driving mechanism such as a plunger can be used as a mechanism for this.

The first printing unit 4, the second printing unit 23, the driving units of the first conveying rollers 27 and 28 and the second conveying rollers 29 and 30, the driving unit of the form stopper 31, the check paper The sensor 32, the magnetic head 33, and the like are connected to the CPU and the R via an interface (not shown) and a bus.

Here, the control unit recognizes and determines the detection or reading result of the check paper sensor 32 and the magnetic head 33, and based on the result, the first printing unit 4, the second printing unit 23, the first printing unit It has a function of controlling the operation of each part of the multifunction device 1 such as the drive units of the transport rollers 27 and 28 and the second transport rollers 29 and 30 and the drive unit of the form stopper 31.

The multifunction device 1 according to the present embodiment
In addition to the above-mentioned check paper S, for example, A4 size slip paper or the like can be conveyed, and the first printing unit 4 performs predetermined printing on such slip paper. Things.

FIG. 4 shows a first embodiment of the control method of the multifunction device according to the present invention.

First, in step S1, the control waits for the setting of the check paper S. That is, the lower roller 28 of the first paper feed rollers 27, 28 is moved to the position shown by the dotted line in FIG. 3 to open the first paper feed rollers 27, 28 and transport the form stopper 31. Protrude into the path. Therefore, in this state, as shown in FIG. 2, the operator places the check paper S face up (the side on which the MICR characters are printed) upward and sets the side end of the check paper S on the main body frame 6. The paper is inserted from the paper insertion slot 26 along the guide 6a. As a result, the leading end of the check sheet S abuts against the foam stopper 31, and the side end of the check sheet S is positioned at a predetermined position along the guide portion 6a. This predetermined position is a reference position of the check sheet S, and the subsequent processing, that is, M
Each process of reading an ICR character, endorsement printing, and front / back printing is performed.

When the leading edge of the check sheet S is detected by the check sheet sensor 32, it is determined that the check sheet S has been set securely, and the process of step S2 is started.

In step S2, the check paper S is transported in the discharge direction (the direction of arrow F). That is, the lower roller 28 of the first paper feed rollers 27, 28 is moved to the position shown by the solid line in FIG. 3, the first paper feed rollers 27, 28 are closed, and the check paper S is gripped. Then, the form stopper 31 is retracted from the transport path. And the first
The check paper S is conveyed in the direction of arrow F by rotating the paper feed rollers 27 and 28 in the forward direction.

In this embodiment, the form stopper 31 is used to position the leading end of the check paper S.
The present invention is not limited to this. That is, in the case where the form stopper 31 is not provided, when the check paper S is detected by the check paper sensor 32, the first paper feed rollers 27 and 28 are closed and the check paper S is gripped. The sheet is transported in the direction of arrow B until it is no longer detected by the sensor 32. Then, the sheet is gradually conveyed in the direction of arrow F and stopped at the position where the check sheet S is detected by the check sheet sensor. Thereby, the leading end of the check sheet S can be positioned at the position of the check sheet sensor, that is, the reference position.

In step S3, the transport of the check paper S is temporarily stopped when the check paper S reaches a predetermined position. The predetermined position is a position at which the end of the MICR character string has passed the detection unit of the magnetic head 33. This processing is called cueing processing.

In step S4, the first paper feed roller 2
7 and 28 are rotated in the reverse direction to transport the check paper S in the direction opposite to the discharge direction (the direction of arrow B) while the magnetic head 3
By driving No. 3, MICR characters recorded on the front side of the check sheet S are read. Here, driving the magnetic head means reading a change in the magnetic field due to MICR characters while generating a bias magnetic field.
When the reading is completed, the conveyance is stopped.

In step S5, the validity / invalidity of the check sheet S is determined based on the reading result of the MICR head. If it is determined that the check paper S is invalid, the process proceeds to step S6, and if it is determined that the check paper S is valid. Move to step S8. Here, the case where the check paper S is invalid means the case where the check paper S is not properly inserted, the case where slip paper other than the check paper S is inserted, the case where the check itself is invalid, and the like. .

Note that this determination may be made by the apparatus of this embodiment, but may also be made by the host device to which this apparatus is connected.
That is, the character code and the status data, which are the read results, are transmitted from the apparatus to the host apparatus, the host apparatus makes the above determination based on the character code and the status data, and the apparatus receives the result. As a result, it is possible to make a determination using more advanced processing such as an inquiry to the bank that issued the check.

In step S6, the check paper S is transported in the direction opposite to the discharge direction, and in step S7, the check paper S is discharged from the paper insertion port 26 as it is. This processing may be automatically performed by the apparatus based on the above result, but when the apparatus is connected to the host apparatus,
It may be performed in response to a command from the host device. As a result, more flexible processing can be performed.

In step S8, the first paper feed roller 2
7 and 28 are rotated in the forward direction, and the check sheet S is transported again in the discharge direction in preparation for the subsequent printing process. Note that the transfer processing can be performed in response to a predetermined command from the host device.

In this case, the first transport rollers 27 and 28 are moved from the second transport roller 2 by the following procedure, for example.
Delivery of the check sheet S to 9 and 30 is performed. That is, the roller 30 on the second printing unit 23 side of the second transport rollers 29 and 30 is moved to the position shown by the dotted line in FIG.
When the leading end of the check sheet S reaches the position between the second transfer rollers 29 and 30, the transfer of the check sheet S is temporarily stopped,
Then, the roller 30 is moved to the position shown by the solid line in FIG. 3 to grip the check paper S, and the second transport rollers 29 and 30 are rotated in the forward direction to transport the check paper S in the direction of arrow F. In this case, if the operation of the mechanism for opening and closing the first and second transport rollers is sufficiently fast, the transport of the check paper S does not necessarily need to be stopped.

In step S9, the second printing unit 23 is driven to perform endorsement printing on the back side of the check paper S, and the first printing unit 4 is driven to perform front end printing on the front side of the check paper S. I do. Note that these printing processes can also be performed based on print data and other control commands received from the host device. In this case, printing is performed while conveying the check paper S in the directions of the arrows F and B as needed. Thereafter, in step S10, the check paper S is further transported in the direction of arrow F and discharged from the discharge port 20a. Such a discharging process may be performed in response to a command from the host device.

As described above, in the present embodiment, the first and second printing units 4 and 23 for performing front and back printing and backing printing are provided on each side of the check paper S, and read MICR characters. After the check paper S is conveyed in the discharge direction and simultaneously or in parallel, the front and rear prints are performed, so that the check paper S is only loaded once in the apparatus and operated. All processing can be performed.

As a result, according to the present embodiment, the processing time can be greatly reduced, and it is not necessary to turn over the check paper S, so that the operation performed by the operator can be simplified.

Furthermore, in the case of the present embodiment, the check sheet S can be loaded with the MICR character recorded side up, so that the operator can set the check sheet S while looking at the front side of the check sheet S. Therefore, the loading operation of the check paper S can be easily performed.

In this embodiment, the roll paper transport mechanism 3 for transporting the roll paper R via the printing position of the first printing unit 4 is configured to be rotatable.
By rotating the roll paper transport mechanism 3, an inking member such as a ribbon cassette of the second printing unit 23 can be easily replaced.

Further, since the second printing unit 23 is constituted by a printing unit that is detachable from the apparatus main body, the second printing unit 23 can be handled as an optional part. You can expand your options.

Furthermore, since the second printing section 23 has a print head of the impact shuttle system, the second printing section 23 can be made thin and small, thereby reducing the size of the apparatus. Can be achieved.

When the MICR character is read by the magnetic head 33 while the check paper S is conveyed in the direction opposite to the discharge direction (the direction of the arrow B) as in this embodiment, the first conveying rollers 27 and 28 must be When the check paper S is arranged on the upstream side of the magnetic head 33 and pulled out from the magnetic head 33 and its pressing member, the check paper S
Even when the check sheet S is thin and has low rigidity, the transport speed of the check sheet S passing through the magnetic head 33 is stable, and the reading accuracy is improved.

FIG. 5 shows a second embodiment of the control method of the multifunction device according to the present invention.

In step S21, as in the case of the above embodiment, the setting of the check sheet S is waited. When the setting of the check sheet S is detected, in step S22,
The check paper S is gripped. If necessary, MIC
The check sheet S may be transported in the direction of the arrow F or B so that the leading end of the R character string is located at the reading unit of the magnetic head.

In step S23, the MICR characters on the front surface of the check sheet S are read by the magnetic head 33 while the check sheet S is being conveyed in the discharge direction. Prior to this processing, it is desirable that the second transport rollers 29 and 30 be opened. This is because if the check sheet S is closed, the leading edge of the check sheet S collides with the roller, and the transport speed of the check sheet S changes, which may cause a reading error.

In step S24, the above-described step S5
Similarly to the above, the validity / invalidity of the check sheet S is determined based on the result of reading by the MICR head. If it is determined that the check paper S is invalid, the process proceeds to step S25. If it is determined that the check paper S is valid, the process proceeds to step S27. Transition. Here, the case where the check sheet S is invalid means that the check sheet S is not properly inserted, that a slip sheet other than the check sheet S is inserted, that the check sheet S itself is invalid, or the like. It is.

This determination may be made by the apparatus of the present embodiment, but may also be made by the host device to which the present apparatus is connected.
That is, the character code and the status data, which are the read results, are transmitted from the apparatus to the host apparatus, the host apparatus makes the above determination based on the character code and the status data, and the apparatus receives the result. As a result, it is possible to make a determination using more advanced processing such as an inquiry to the bank that issued the check.

In step S25, the check paper S is transported in the direction opposite to the discharge direction, and in step S26, the check paper S is discharged from the paper insertion port 26 as it is. Note that the transfer processing can be performed in response to a predetermined command from the host device.

In step S27, the second printing unit 23 further transports the check sheet S in the discharge direction to a predetermined position near the rear end of the check sheet S where printing is possible, in preparation for the subsequent printing process. If the check paper S is located closer to the paper discharge port 26 than the position at the end of the MICR reading, the check paper S is transported in a direction opposite to the discharge direction. Further, the transfer processing can be performed in response to a predetermined command from the host device.

In step S28, the second printing unit 23 prints endorsement on the back side of the check paper S while transporting the check paper S in the direction opposite to the discharge direction. In addition,
This printing process can also be performed based on print data and other control commands received from the host device. In this case, printing is performed while conveying the check paper S in the directions of the arrows F and B as needed.

After the endorsement printing, in step S29, the check paper S is further transported in the direction opposite to the discharge direction. In step S30, the cueing position of the check sheet S is confirmed by detecting the lower end of the check sheet S by the check sheet sensor 32.

In step S31, after cueing of the check paper S is performed by the above-described method, the first printing unit 4 performs front-side printing on the front side of the check paper S while transporting the check paper S in the discharge direction. . This printing process can also be performed based on print data and other control commands received from the host device. In this case, printing is performed while conveying the check paper S in the directions of the arrows F and B as needed.

In step S32, the check sheet S is further transported in the discharge direction and discharged from the discharge port 20a. Note that the transfer processing can be performed in response to a predetermined command from the host device.

According to the present embodiment, all the processing can be performed only by loading and operating the check paper S in the apparatus once, and even when slip paper of different size is processed. In addition, front and back printing and back printing can be reliably performed on the check sheet S.

Further, since the first print head and the second print head do not print at the same time, the peak current used can be reduced, and the power supply and the elements constituting the circuit can be manufactured at low cost. Can be small.

When the MICR characters on the front surface of the check paper S are read by the magnetic head 33 while the check paper S is being transported in the discharge direction as in the second embodiment, the first transport rollers 27 and 28 are moved. If the check paper S is drawn out of the magnetic head 33 by being disposed downstream of the magnetic head 33, the transport speed of the check paper S passing through the magnetic head 33 is stable even if the check paper S is thin and its rigidity is weak. The reading accuracy is improved.

It should be noted that the present invention is not limited to the above-described embodiment, and various changes can be made. For example,
In the above-described embodiment, the first and second printing units that perform printing using a ribbon cassette type ink ribbon are used. However, the present invention is not limited to this. It is also possible to use a device that performs printing according to the conditions. In that case, there is an advantage that the sound at the time of printing can be made quieter and that the accuracy of the gap between the print head and the platen does not need to be set so high.

Alternatively, a thermal printer of a thermal transfer system in which ink is welded to the first and second printing portions from a ribbon and transferred to a recording medium may be used. Moreover, it is desirable that the ribbon be a multi-type ink ribbon that can be printed a plurality of times. In this case, the sound at the time of printing can be made quiet and the entire apparatus can be made thin.

Further, an ink jet printer or a thermal transfer thermal printer may be used for only the second printing section. In this case, since the second printing unit is endorsed, the number of printing lines and the number of printings is small, and printing on multi-sheet paper is not required, and the printing quality is much better than the impact method. It is effective from.

Although the description has been made using the check paper as the recording medium, any material that can print on both sides may be used. For example, even if the sheet material is in a roll shape, or formed of a printable resin. A film-like sheet may be used. In the case where a resin recording medium is used, the first and second printing sections are more effective with an ink jet printing head.

Further, the example in which the pressing roller is used as the mechanism for bringing the check paper S into close contact with the magnetic head 33 has been described.
It does not matter if it does not rotate. In this case, it is desirable that the friction coefficient with the check paper S be small so as to reduce the transport load.

In the apparatus of this embodiment, the roll paper transport mechanism 3
Is provided so as to be rotatable around the support shaft 12, and prints on the roll paper R by the print head 4a when in the closed state (the state shown by the solid line in FIG. 1). However, the present invention is not limited to such a configuration, and a print head dedicated to the roll paper R may be provided in the transport path of the roll paper transport mechanism 3. This print head is desirably a thermal head, and its structure is described, for example, in Japanese Patent Laid-Open No. 9-1415.
No. 95 (US patent application Ser. No. 08 / 752,782).
