1. Field of the Invention
The present invention relates to an image forming apparatus for printing image information where a cutting mark is printed on the recording medium.
2. Related Art
In recent years, image forming apparatuses may print a cutting mark on a recording medium in addition to image information to be printed. The cutting mark identifies a cutting position and makes it easy for the cutting machine to cut the recording medium after printing, thereby improving work efficiency.
Owing to recent progress of an image recognition technology, the cutting machine reads the mark for cutting on a recording medium, and cuts the recording medium automatically based on the position of the read cutting mark. To read the mark, the cutting machine requires the cutting mark to have a definite form that is peculiar to the cutting machine, and conducts cutting at the position thus read. For instance, the cutting mark is received by the image forming apparatus from a personal computer or PC, together with the image information, under the condition that the cutting mark is combined in image information. One such cutting machine is described for example, in Japanese Non-Examined Patent Publication No. 2002-292831. However, in the aforesaid related art, erroneous cutting is caused when a recording medium is cut by the cutting machine. Namely, erroneous reading is caused when a cutting mark which the cutting machine can read is not compatible with a cutting mark printed on the recording medium.
When the cutting machine makes an erroneous reading, in particular, the output recording medium may be defective because the cutting position may be different from the targeted position. This defective output causes wastefulness of recording media and reduction of printing efficiency. Such systems also do not allow an operator to make changes easily, and thus causes improvement of defective output to be time-consuming, because the cutting mark is attached to the image information input to the image forming apparatus.
Apart from the above mentioned reason, to print the image information and the cutting marks on a recording medium, the printing area including the image information and the cutting marks will be larger than the original area of the image information. The printing area may exceed to the area of recording medium; therefore, there is a possibility that a defective output is produced by the cutting machine because the cutting marks may not be able to be printed on the recording medium.
For the above reasons, an image forming apparatus, method and system that can prevent the cutting machine from generating defective cutting output.
The invention is one to be achieved to solve the problems in the related art, and its object is to provide an image forming apparatus, method and system that can produce printing outputs that can prevent the cutting machine from generating a defective cutting output.

The preferred exemplary embodiment to practice an image forming apparatus consistent with the invention will be explained with reference to the attached drawings. The invention is not limited to this embodiment, which is intended to be only exemplary. The proper scope of the invention is defined by the appended claims.
As shown in
The PC 10 is a personal computer which sends image information to the printer 30 through the LAN 40. The scanner 20 is an image information reading apparatus which sends image information to the printer 30 through the LAN 40. The printer 30 represents an image forming apparatus in which the image information output by the PC 10 or the scanner 20 is printed on a recording medium, such as a transfer sheet or a recording sheet. For example, the printer 30 is an electrophotographic printer or an ink jet printer that discharges ink drops.
The cutting machine 50 cuts the printed recording medium outputted from the printer 30 to a prescribed size. In this regard, the cutting machine 50 may read a position of the cutting mark (which is also referred to herein as a register mark) on the recording medium, and may then cut the recording medium based on this position information. For example, the recording medium is cut at cross-shaped register marks printed on four corners of the recording medium. Incidentally, a shape of the register mark to be used varies depending on a type of the cutting machine. Further, the recording medium outputted from the printer 30 may be subject to batch processing conducted by an operator of the cutting machine 50.
The LAN 40 is a communication cable through which image information and other data maybe transmitted and received among the PC 10, the scanner 20 and the printer 30, by the use, for example, of the CSMA/CD communication protocol.
The operation section 34 has an input device, such as a display portion of an LCD (Liquid Crystal Display), a touch panel or a ten key representing numeric keys. The input device may be used for setting various operation parameters for the printing process. Section 34 may also set the register mark, which will be explained in greater detail below.
The control section 32 controls the printer 30 and further includes a central processing unit (or CPU) and a memory. Section 32 may control the printer 30 based on one or more conditions established by the operation section 34. As will be explained in greater detail below, the control section 32 may compose image data of a register mark and the inputted image information by attaching the register mark to the image information.
The image forming section 33 receives a recording medium from a sheet-feeding tray and prints an image on the recording medium based on printing conditions output by the control section 32. Section 33 may then output the printed recording medium to an output tray.
The register mark information 61 preferably includes multiple register mark patterns. Each pattern, for example, may be a version of a base register mark. For instance, FIGS. 4(a) to 4(d) show exemplary register mark patterns that may be stored in the register mark information 61. FIGS. 4(a)-4(d) each illustrate a register mark pattern that may be arranged at the four corners of an image forming a rectangular plane.
As described above, the register mark information 61 may have register mark pattern information including cross-shaped, L-shaped, and center-missing L-shaped register marks as illustrated in FIGS. 4(a)-4(d).
Referring back to
Incidentally, in accordance with instructions output by operation section 34, a register mark may be selected from the register mark information 61, and may be transmitted to the attaching device 63. Further, in the same way, register mark size and/or position information 62 may be generated and transmitted to the attaching device 63 in accordance with instructions from operation section 34.
The image memory 64 is a memory that stores image information outputted from image forming section 33. Contents of this memory form printing output information which may be printed to agree with the size of a recording medium defined by the operation section 34. Therefore, the size of a printing output range may agree with the size of the memory 64 and the size of the recording medium. When contents of the memory 64 need to be preserved in the control section 32, the contents of the memory 64 may be subject to an image compression, and may then be subject to image decompression for printing.
Attaching device 63 may attach a register mark on image information 60 based on the image information 60, register mark information 61 and register mark size and/or position information 62. Device 63 may then store the register mark in image memory 64.
In systems consistent with the invention, the attaching device-63 confirms a print range representing a minimum rectangular area surrounding the image information 60 and the register marks to be arranged in the image memory 64. The device 63 may then compute a printing range that has a blank region with a prescribed width around the periphery of the print range. After that, when the printing range exceeds the printing output range of the page memory 64 (which corresponds to a size of the recording medium), the attaching device 63 may discontinue writing data to the image memory 64, and transmit a warning signal to operation section 34. The operation section 34 may then receive the warning signal and display the warning on the display section.
The attaching device 63 may have a changing device that may change a width of a blank region based on the register mark size and/or position information 62. When the selected register mark is relatively large, the changing device may make the blank large, so that cutting may be conducted by cutting machine 50 properly. The specific relationship between a size of the register mark and a width of the blank region may be adjusted for the particular application based on routine experimentation.
Next, operations of a printer 30 having a control section 32 will be explained with reference to
Referring back to
In this regard, after the step S615 is carried out, the display to the effect that “image size is too large to print register mark” may appear on the comment column on the upper part of the image area, as shown in
When a size of a recording medium is greater than or equal to the image size (“YES” in step S602), the control section 32 indicates “possibility of register mark printing” on the display section of the operation section 34 (step S603).
An operator may then select the register mark printing button (step S604), and inputs a register mark pattern showing a shape of a register mark, a size of the selected register mark pattern, and/or a position of the register mark through the operation section 34 (step S605).
Next, attaching device 63 of the control section 32 may determine whether the recording medium size is equal to or greater than a printing range of image information 60 having the attached selected register marks (step S606). In this case (“YES” in step S606), the attaching device 63 may generate the image in image memory 64 (step s607) because all image information can be printed when the recording medium size is equal to or greater than the printing range.
The control section 32 may then determine, based on key operations conducted by an operator of the operation section 34, whether to confirm the output (step S608). If the output is to be confirmed (“YES” in step S608), the control section 32 confirms the output (step S609 in
Further, when no confirmation output is conducted (“NO” in step S608), the control section 32 moves the processing flow directly to step S611 to print the image and end the processing.
Referring back to step S606, when a recording medium size is smaller than a printing range of image information 60 having the attached register marks (“NO” in step S606), the control section 32 displays “impossibility of printing” on a display section (step S612). For example, by using a display image area such as that shown in
The operator may then select whether to require the system to still print the image information 60 having the attached register mark or whether to clear the image information (step S613). When the operator selects the clear button(“YES” in step S614 in
In the above exemplary embodiment, printer 30 uses attaching device 63 to attach register mark information 61 having a specified shape, size, and position to image information 60 for reading by a cutting machine 50. Further, according to the above exemplary embodiment, when a printing range of the image information 60 with the attached register mark exceeds a printing output range representing a size of image memory 64 or a recording medium size, a warning is given to discontinue printing, which prevents erroneous reading of the register mark by the cutting machine, reduces defective output of a recording medium from the cutting machine and improves printing efficiency.
Though the exemplary register marks described above are cross-shaped marks and L-shaped marks, the register marks may also be a point or any peculiar or identifying mark, provided that the register mark may be identified or read by cutting machine 50.
Further, though the attaching device 63 is described as part of the control section 32, the attaching device 63 may also be present on the image processing section 31 or on the image forming section 33.
(marginal distance amount between image information 60 and register mark 61)=(width of recording medium−width of image information 60−width of register mark 61)/2.
Where the “marginal distance amount between image and register mark” is a negative value as a result of the above calculation, the system may prompt the operator to select between re-inputting the register mark size or designating the register mark position.
When the position or size of the register mark is automatically calculated, the values will be determined such that the size of the recording medium is equal to or greater than the size of the printing range of image information 60 having the attached register marks. Accordingly, the system will generate the image in image memory 64 (step S607) and then print the image (step S611) to end the process.
On the other hand, as shown in
If “NO” in step S606, then, as shown in
When “correction of input” is selected (not shown in
