2. Description of the Related Art Among popular printers,
As a printing paper, there is a printing paper that uses a roll paper formed by winding paper continuously formed in the printing direction. When such a roll paper is printed by a printer, the user needs to cut the roll paper at an appropriate position after printing is completed. That is, it is necessary for the user to perform a work of cutting the printing paper after the printing is completed by using a cutting tool such as a cutter or scissors.

Further, some printers capable of printing such roll paper are provided with a cutter for automatically cutting the roll paper at a designated place. In the case of such a type of printer, when the roll paper reaches a position to be cut, the cutter automatically operates to cut the roll paper.

For example, in the case where the cutter is an optional printer, the cutter is attached after the product is completed, so that a slight error may occur between the position where the cutter is actually attached and the position preset in the printer. It is desirable that this error be as small as possible.

Some conventional printers have a correction mechanism for correcting this error. When using this correction mechanism, the customer engineer, the user, or the like actually prints on the roll paper and then cuts it using the cutter provided in the printer.
The amount of deviation is measured with a ruler or the like. Then, based on the measurement result, the deviation amount is input to the printer as a correction value. When the correction value is input, the printer cuts the roll paper at the position corrected based on this correction value.

Then, the customer engineer, the user, or the like can easily know the deviation amount to be input by simply reading the cutting position of the deviation amount reading pattern, and can easily set the correction value of the printer. It was done. More details will be described below.

First, the paper feed and cutting mechanism of the printer PRN according to this embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a conceptual diagram for explaining the paper feed / cutting mechanism of the printer PRN according to the present embodiment from the cross-sectional direction.
FIG. 3 is a conceptual diagram illustrating this from the top surface direction.

As shown in FIGS. 1 and 2, the printer PRN according to the present embodiment is a printer that can use roll paper as printing paper, and the printing paper wound in a roll shape on the roll unit 10 can be used. It is installed. And
By pulling out one end side of the printing paper from the roll unit 10, the printing paper 12 is supplied to the paper path. In the present embodiment, the direction in which the printing paper 12 is sent to the paper path is called the paper discharge direction, and conversely, the direction in which the printing paper 12 returns to the roll unit 10 is called the paper feed direction. Further, the direction along the paper discharge direction and the paper feed direction is referred to as a continuous direction of roll paper.

Movement of the printing paper 12 in the paper ejection direction, and
The rubber roller 20 and the rubber roller 2 move in the paper feeding direction.
This is performed by driving and rotating 2 and. That is,
These rubber rollers 20 and 22 are drivingly connected to a drive motor 24, and when the drive motor 24 drives, the rubber rollers 20 and 22 also drive.

At the position of the rubber roller 20, the printing paper 12 is
Is sandwiched between the rubber roller 20 and the plastic support portion 26. Further, at the position of the rubber roller 22, the printing paper 12 is sandwiched between the rubber roller 22 and the serrated roller 28. Therefore, when the rubber rollers 20 and 22 rotate, the friction causes the printing paper 12 to move in the paper discharge direction and the paper feed direction. In the present embodiment, when the print paper 12 is moved in the paper discharge direction, the drive motor 22
Is rotated clockwise to move the printing paper 12 in the paper feeding direction, the drive motor 22 is rotated counterclockwise.

The printing paper 12 sent from the position of the rubber roller 20 in the paper discharge direction is printed by ejecting ink at the position of the print head 30. Specifically, the print head 30 is mounted on a carriage 32, and when the carriage 32 moves from the home position to the light position and from the light position to the home position, the print head 30 is used. Printing is done. During this movement, the print head 30 prints by ejecting ink onto the printing surface (upper surface in FIG. 1) of the printing paper 12.

Further, the printing paper 12 delivered in the paper discharge direction on this paper path reaches the position of the notched roller 28. As shown in FIG. 1, in this embodiment, the serrated roller 28 is provided with a gear-shaped groove on its peripheral surface for preventing slippage. Also, as shown in FIG.
In the present embodiment, the serrated roller 28 is the rubber roller 2

Further, the printing paper 12 sent out from the serrated roller 28 in the paper discharge direction reaches the position of the cutter 50. The cutter 50 includes a blade portion 54 for cutting the printing paper 12 and a blade support portion 52 that supports the blade portion 54. When the cutter 50 cuts the printing paper 12, the cutter 50 descends to the position shown by the dotted line in FIG. 1, and the tip of the blade portion 54 comes to be located below the printing paper 12. In this state, as shown in FIG.
When the cutter 50 moves from the home position to the light position, the blade portion 52 causes the printing paper 12 to move.
Is disconnected. That is, the cutting operation is performed by moving the cutter 50 in the direction intersecting the continuous direction of the printing paper 12. Particularly in this embodiment,
The cutter 50 moves in a direction orthogonal to the continuous direction.

Further, as shown in FIG. 1, cutter retainers 60, 60 are provided on the side of the cutter 50 in the sheet feeding direction. When the printing paper 12 is fed in the paper discharge direction and the paper feeding direction in normal printing, the cutter pressers 60, 60 do not sandwich the printing paper 12 so as not to hinder the movement of the printing paper 12. ing. That is,
As shown in FIG. 1, the cutter holder 60 on the upper side of the printing paper 12 and the cutter holder 60 on the lower side are separated from each other.

When the cutter 50 moves from the home position to the light position to cut the printing paper 12, the space between the upper cutter holder 60 and the lower cutter holder 60 is narrowed, and the printing paper 12 is sandwiched. Will be in a state to support. Accordingly, the cutting by the cutter 50 can be smoothly performed without the printing paper 12 being displaced.

Next, based on FIG. 3, the printer PRN and the host computer C of the printing system according to the present embodiment.
The configuration of the OM will be described. FIG. 3 is a block diagram showing a hardware configuration of the printer PRN and the host computer COM included in the printing system according to this embodiment.

As shown in FIG. 3, the printer PRN mainly includes a CPU 100 and a RAM (Random Access Memory).
102, a ROM (Read Only Memory) 104, a machine control unit 106, and an EEPROM (Electrically Erasabl)
e Programmable ROM) 108 and interface 11
0, which are connected to each other via an internal bus 120.

The CPU 100 has a RAM 102 and a ROM 1
Load various programs stored in 04,
Do this. If necessary for execution, R
The data stored in the AM 102, the ROM 104, and the EEPROM 108 are read and used. Although described later in detail, in the present embodiment, the EEPROM is used.
The cutter correction value is stored in 108, and the CPU 10
0 or the machine control unit 106 operates the cutter 50, the cutter correction value is read from the EEPROM 108.

When it is necessary to operate or stop each machine part shown in FIGS. 1 and 2, C
The PU 100 sends the command to the machine control unit 106.
The machine control unit 106 controls necessary machine units based on the received command. For example, the machine control unit 1 that has received a command to operate the cutter 50 to cut the printing paper 12
Reference numeral 06 generates a control signal necessary for that purpose, moves the cutter 50 from the home position to the light position in a state where the printing paper 12 is sandwiched by the cutter pressers 60, 60, and executes the cutting operation. Further, the machine control unit 106, which has received the command to rotate the drive motor 24 clockwise by 600 steps, generates a control signal necessary for that purpose and rotates the drive motor 24 clockwise by 600 steps.

The printer PRN is connected to the host computer COM via the interface 110. Specifically, the interface 110 of the printer PRN is connected to the interface 200 of the host computer COM. The connection between the printer PRN and the host computer COM may be a local connection using USB or the like, or may be a network connection using Ethernet (registered trademark) or the like.

The host computer COM has the interface 200, the CPU 202, and the RAM 204.
And a ROM 206, which are mutually connected via an internal bus 210. In the present embodiment, the user normally uses this host computer COM.
The print data is created according to, the print data is transmitted to the printer PRN, and the printer PRN prints.

Next, referring to FIG. 4, a cutting position correction mechanism provided in the printer PRN according to this embodiment will be described. FIG. 4 is a diagram for explaining the concept of the cutting position correction mechanism according to the present embodiment.

As shown in FIG. 4, the printing paper 12 pulled out from the roll paper is printed at the position of the print head 30 and cut at the position of the cutter 50. That is, there is a distance between the printing position and the cutting position.
This distance is referred to as a cutter head gap in this embodiment. This cutter head gap is 6416/1440 inches (about 113.17 mm) in this embodiment. In the printer according to the present embodiment, the movement of the printing paper 12 is controlled in units of 1/1440 inch (about 0.018 mm).

Further, the printer PRN according to the present embodiment
Holds the cutter correction value in the EEPROM 108. The cutter correction value is a numerical value for correcting an error between the cutting position calculated by the printer PRN (that is, the designed mounting position of the cutter 50) and the actual mounting position of the cutter 50. That is, the printer P
The position where the cutter 50 performs the cutting operation is the position where the cutter correction value is added to the cutting position calculated by the RN. In the example of FIG. 4, the cutter correction value is −10/14.
40 inches (about -0.18 mm) is the EEPROM 108
Stored in.

For example, in FIG. 4, it is assumed that the page top position (vertical printing position), which is the reference for the movement of the printing paper 12, is 2000. The position where the printer PRN is to be disconnected is 250/14 from the top of the page.
It is assumed that the position is advanced by 40 inches (about 4.41 mm) in the paper discharge direction. In this case, the printer is 2000 + 25
After moving the printing paper 12 to the position of 0 + 6416-10 = 8656/1440 inches, the cutter 50 may be operated.

Next, with reference to FIG. 5, a process when a customer engineer, a user or the like obtains this deviation amount and sets and inputs a cutter correction value in the printer PRN will be described. FIG. 5 is a flowchart for explaining the processing of the host computer COM and the printer PRN when the customer engineer, the user or the like knows the deviation amount and sets and inputs the cutter correction value of the printer PRN.

As shown in FIG. 5, first, a customer engineer, a user or the like operates the host computer COM to send a cutter adjustment command to the printer PRN (step S10). Specifically, the customer engineer, the user, or the like operates the host computer COM to instruct the host computer COM to send a cutter adjustment command for printing the deviation amount reading pattern to the printer PRN. Upon receiving this instruction, the host computer COM sends a cutter adjustment command to the interface 110 of the printer PRN via the interface 200.

The printer PRN that has received this cutter adjustment command displays the deviation amount reading pattern on the printing paper 12.
(Step S11). FIG. 6 is a diagram showing an example of a deviation amount reading pattern printed by the printer PRN according to the present embodiment. As shown in FIG. 6, in the shift amount reading pattern according to the present embodiment, a reference line 300 that is a zero point, a positive side correction scale 310, and a negative side correction scale 320 are printed. . In addition, the correction scale 31
In 0 and 320, the shift amount to be input is printed in numerical values in millimeters.

Next, as shown in FIG. 5 again, the printer P
The RN uses the reference line 300, which is the zero point, as a reference to locate the cutter / head gap at that time, and the EEPROM 10
The distance added with the cutter correction value stored in 8,
The print paper 12 is moved in the paper discharge direction (step S1).
2). Next, the printer PRN cuts with the cutter 50 (step S13). Specifically, the cutter 5
The print sheet 12 is cut by moving 0 from the home position to the light position, and the cutter 50 is returned from the light position to the home position. According to this cutting operation, the proper cutter correction value is E
If it is held in the EPROM 108, the cutting position should be the position of the reference line 300 that is the zero point.

Next, the printer PRN ejects the printing paper 12 (step S14). Specifically, after the printing paper 12 is further moved by a predetermined amount in the paper ejection direction, the printing paper 12 is cut by the cutter 50.

Next, the customer engineer, the user, or the like observes the printed shift amount reading pattern,
The position where the cutter 50 is cut is specified, and the shift amount is grasped. For example, in FIG. 6, when the printing paper 12 is cut at the position indicated by the alternate long and short dash line, the customer engineer, the user, or the like can know that the shift amount is +2 mm.

Therefore, the host computer COM is
The customer engineer, the user, or the like is prompted to input the amount of deviation (step S15). That is, the customer engineer, the user, or the like operates the host computer COM to input the shift amount into the host computer COM.
In this example, +2 mm is input as the shift amount. The host computer COM to which the shift amount has been input transmits this shift amount to the printer PRN together with the correction value change command (step S16).

The printer PRN that has received the deviation amount together with the correction value change command sets a value obtained by adding the deviation amount to the current cutter correction value as a new cutter correction value and stores it in the EEPROM 108 (step S1).
7). In the example of FIG. 6, the cutter 50 cuts the position of +2 mm, which means that if the printing paper 12 is moved in the paper discharge direction by another 2 mm, the cutting is performed at the position of the reference line 300 that is the zero point. Means Therefore, an appropriate cutter correction value can be calculated by adding the input deviation amount to the existing cutter correction value.

Further, in the present embodiment, the printer P
The RN converts the deviation amount received in millimeters into inches. For example, the shift amount of +2 mm is 113/1440
Convert to inches. Then, the cutter correction value up to that time is 10/1440 inches, and the deviation amount is 113 /
1440 inch is added to calculate 123/1440 inch as a new cutter correction value. Then, the new cutter correction value 123/1440 inches is set to EEP.
It is stored in the ROM 108. The conversion from millimeter units to inch units may be performed on the host computer COM side and then transmitted to the printer PRN. With the above, the cutter adjustment process in the printing system according to the present embodiment is completed.

As described above, according to the printing system of this embodiment, the customer engineer, the user, etc.
In order to set the cutter correction value of the printer PRN to an appropriate value, the printer PRN is caused to print a deviation amount reading pattern, which is then cut using the cutter 50. Then, it suffices to read the position cut by the cutter 50 from the shift amount reading pattern and input the read value as it is to the host computer COM as the shift amount. That is, the displacement amount to be input to the host computer COM can be known only by reading the cut position of the displacement amount reading pattern shown in FIG. Therefore, the labor required by the customer engineer or the user to set the cutter correction value can be significantly reduced.

The present invention is not limited to the above embodiment and can be variously modified. For example, in the above-described embodiment, the cutter adjustment command, which is a print execution command for the deviation amount reading pattern, is input from the host computer COM. However, the printer PRN is directly operated by operating the control panel or the like of the printer PRN. May be input to. Similarly, in the above-described embodiment, the shift amount is input from the host computer COM, but it may be input directly from the control panel or the like of the printer PRN.

Further, in the above-mentioned embodiment, the shift amount to be input by the customer engineer or the user is
Although both the correction scales 310 and 320 and their numerical values are printed as the input shift amount information, only one of them may be printed. That is, the input deviation amount information may be configured by the correction scales 310 and 320, or may be configured by correction numerical values.

Further, in the above-described embodiment, the roll paper is described as an example of the continuously formed print medium, but the print medium is not limited to the roll paper and, for example, the OHP transparent sheet is continuously formed. The present invention can be applied to a print medium that is formed in a specific manner. Furthermore, in the above-described embodiment, an inkjet printer has been described as an example of a printer, but the present invention can be applied to any printer that prints on a continuously formed print medium.

Further, in the above-mentioned embodiment, the cutter 50 is exemplified as the cutting means, but the printing paper 12 is used.
The cutting method and the cutting tool are not limited to the above as long as they have a function of cutting.

Further, regarding each process described in the above-mentioned embodiment, a program for executing each process is stored on a flexible disk or a CD-ROM (Compact Disk).
It is possible to record on a recording medium such as a sc-read only memory), a ROM, a memory card, and distribute the recording medium. In this case, the above-described embodiment can be realized by causing the printer PRN or the host computer COM to read and execute a recording medium on which this program is recorded.

The printer PRN and the host computer COM may include other programs such as an operating system and another application program. In this case, another program provided in the printer PRN or the host computer COM is used, and an instruction for calling a program that realizes the same processing as that of the present embodiment is recorded in the recording medium from the program.
