1. Field of the Invention
The present invention relates to a print sheet creating apparatus and a print sheet creating method.
2. Description of the Related Art
There is known a print sheet having an image formed by transferring toners such as yellow and magenta onto a base sheet. In addition, similarly, there are also known a print sheet creating apparatus and a print sheet creating method which creates the print sheet.
Such a print sheet creating apparatus includes a plurality of image forming units. These image forming units each form images having different colors from each other and stake these images, so that a desired image can be formed.
In Jpn. Pat. Appln. KOKAI Publication No. 2013-068862, besides the print sheet creating apparatus and the print sheet creating method, a print sheet creating apparatus and a print sheet creating method which creates the print sheet formed with a thermal transfer label are also disclosed.
The print sheet having the thermal transfer label is formed by forming a desired image on the base sheet which has separated surfaces, and transferring a thermoplastic resin on the image.
In the thermal transfer print sheet, the surface opposite to the thermal transfer label of the base sheet is thermally pressed in a state where the surface formed with the thermal transfer label abuts on clothes. Therefore, the thermoplastic resin is melt and fused into the fibers of the clothes. Thereafter, the base sheet is removed from the clothes in a state where the thermoplastic resin is cooled and fixed to the clothes, and thus the thermal transfer label is transferred onto the clothes.
In the print sheet creating apparatus and the print sheet creating method described above, the following problems are found out. In other words, the print sheet creating apparatus includes a plurality of unit arranging portions which are capable of disposing the image forming units. An instruction of forming an image to the image forming unit is sent through the unit arranging portion to the image forming unit. In other words, for example, an instruction of forming a yellow image is sent to the unit arranging portion which is disposed in the yellow image forming unit.
In a case where the print sheet creating apparatus is used in a normal printing mode for forming a normal image on the base sheet, and in a case where the thermal transfer label is formed, the image forming units are differently disposed. Therefore, in a case where the apparatus for the normal printing mode is converted for forming the thermal transfer label, for example, the magenta image forming unit for forming the thermal transfer label is disposed in the unit arranging portion in which the yellow image forming unit is disposed for the normal printing mode. In this case, the instruction of forming the yellow image is sent to the magenta image forming unit, and a desired image is not formed. Therefore, the print sheet creating apparatus for forming an image is not possible to form the thermal transfer label. Similarly, the print sheet creating apparatus for forming the thermal transfer label is not possible to form the normal image.
On the other hand, for example, Jpn. Pat. Appln. KOKAI Publication No. 2004-077932 discloses an image forming apparatus which includes a first developing unit to form an image using one or more types of first developers and an attachable second developing unit to form an image using one or more types of second developers different from the first developer. In the disclosed image forming apparatus, there are provided a developing-unit determining unit which determines the type of the developing unit provided in the image forming apparatus and an informing unit which informs a user of an error indicating the reason why an image forming command is not accepted in a case where the user inputs the image forming command to form an image containing the second developer when the second developing unit is not mounted. However, the image forming apparatus is an apparatus which forms an image in an image bearing member and thus the creating of the thermal transfer label is not possible, and the creating of the thermal transfer label is neither described nor suggested.
Furthermore, for example, Jpn. Pat. Appln. KOKAI Publication No. 2007-155824 discloses a tandem type of an image forming apparatus which includes a plurality of image forming units, and forms a color image by transferring toner images of colors created by the respective image forming units on a transfer body in a multiplex manner. The image forming apparatus includes four or more storage portions for storing the image forming units, and execute an image forming mode of forming the color image by using only the first to the third image forming units as the plurality of image forming units in a case where a first image forming unit for magenta is stored in a first storage portion, a second image forming unit for cyan is stored in a second storage portion, and a third image forming unit for black is stored in a third storage portion. However, the image forming apparatus is an apparatus which forms an image in an image bearing member and thus the creating of the thermal transfer label is not possible, and the creating of the thermal transfer label is neither described nor suggested.
Furthermore, for example, Jpn. Pat. Appln. KOKAI Publication No. 02-146567 discloses an image forming apparatus which is mounted with any of a plurality of cartridges having a single developer or a plurality of developer groups and forms a recording image according to an input image data. The image forming apparatus includes an identification unit which identifies the type of the mounted cartridge, a display unit which displays an operating mode according to the identified result, a mode setting unit which sets a mode to operate the apparatus, and a control unit which operates the apparatus in a mode set by the mode setting unit. However, the image forming apparatus is an apparatus which forms an image in an image bearing member and thus the creating of the thermal transfer label is not possible, and the creating of the thermal transfer label is neither described nor suggested.
The invention has been made in view of the above problems, and an object thereof is to provide a print sheet creating apparatus and a print sheet creating method which is capable of performing both the thermal transfer label forming and the normal printing.
In order to solve the problems and achieve the object, the print sheet creating apparatus and the print sheet creating method according to the invention are configured as follows.

The above-described print sheet creating apparatus 1 includes two modes of the normal print mode α and the thermal transfer label creating mode β.
In the normal print mode α, as illustrated in
In the thermal transfer label creating mode β, as illustrated in
The normal print mode α and the thermal transfer label creating mode β are modes in which a full color image is formed using the first resin powder toner T1 of yellow, the second resin powder toner T2 of magenta, and the third resin powder toner T3 of cyan.
Further, in a case where a combination of each unit arranging portion 37, each image forming unit 40, and the binder toner transfer unit 50 is different from any one the normal print mode α and the thermal transfer label creating mode β (a third combination), the printing impossible is output to at least one of the display unit 89, the speaker/buzzer unit 95, and the host apparatus PC.
The above-described print sheet creating apparatus 1 forms the print sheet using a method described below. Further, the following description will be made about a case in which a thermal transfer label R is formed on the second base sheet W2.
When an instruction of forming the thermal transfer label R is issued to the host apparatus PC, image data of the thermal transfer label R is input to the interface controller 82 by the host apparatus PC.
The image data is developed into each image data of yellow Y, magenta M, cyan C, black K, and the binder toner BT by the frame memory 83. The image data of the respective colors and the binder toner BT is sent to the CPU 81 and the printer controller 84.

In a case where the combination of the unit arranging portion 37 and the image forming unit 40 and the binder toner transfer unit 50 acquired from the sensor unit 88 is the same as that of the thermal transfer label creating mode β, an instruction of creating the print sheet is sent from the CPU 81 to the printer controller 84, and further sent from the printer controller 84 to the instruction unit 90.
The instruction unit 90 issues an instruction to the conveyance mechanism 20, the intermediate transfer portion 30 and the fixing device 60.
When the conveyance mechanism driving unit 93 issues the instruction to the second sheet feeding roller 22, the conveyance of the second base sheet W2 is started.
The belt driving unit 92 issues an instruction to the first drive roller 32 and the second drive roller 33, and the printing unit 91 issues an instruction to the image forming unit 40 and the binder toner transfer unit 50, so that the exposure is started at timing illustrated in
Further, the image data of the binder toner BT, the image data of yellow Y and black K, the image data of magenta M and black K, and the image data of cyan C and black K are respectively sent from the printer controller 84 to the first unit arranging portion 37A, the second unit arranging portion 37B, the third unit arranging portion 37C, and the fourth unit arranging portion 37D, and then sent to the image forming unit 40 and the binder toner transfer unit 50 disposed in each unit arranging portion 37.
On the transfer belt 35, the binder toner BT, the first resin powder toner T1, the second resin powder toner T2, and the third resin powder toner T3 are transferred at the image exposure timing illustrated in
In other words, as illustrated in
Thereafter, as illustrated in
The binder toner BT, the first resin powder toner T1, the second resin powder toner T2, and the third resin powder toner T3 on the transfer belt 35 are fed between the first drive roller 32 and the transfer roller 31. Further, the second base sheet W2 is conveyed between the first drive roller 32 and the transfer roller 31 by the instruction of the instruction unit 90 at the timing when the binder toner BT and the respective color toners are fed between the first drive roller 32 and the transfer roller 31. Then, as illustrated in
Thereafter, the binder toner BT and the respective color toners are transferred onto the second base sheet W2 by the fixing device 60, and as illustrated in
As illustrated in
In other words, as illustrated in
Further, in the normal print mode α, as described above, the first image forming unit 40A, the second image forming unit 40B, the third image forming unit 40C, and the fourth image forming unit 40D are respectively disposed in the first unit arranging portion 37A, the second unit arranging portion 37B, the third unit arranging portion 37C, and the fourth unit arranging portion 37D. Therefore, when the CPU 81 determines that the first image forming unit 40A, the second image forming unit 40B, the third image forming unit 40C, and the fourth image forming unit 40D are respectively disposed in the first unit arranging portion 37A, the second unit arranging portion 37B, the third unit arranging portion 37C, and the fourth unit arranging portion 37D, the image data of yellow Y, the image data of magenta M, the image data of cyan C, and the image data of black K are respectively sent to the first unit arranging portion 37A, the second unit arranging portion 37B, the third unit arranging portion 37C, and the fourth unit arranging portion 37D by the printing unit of the printer controller 84.
As described above, the formed print sheet creating apparatus 1 is configured such that the CPU 81 determines whether the combination of each unit arranging portion 37 and the image forming unit 40 and the binder toner transfer unit 50 detected by the sensor unit 88 is a combination which is capable of the forming image data sent from the host apparatus PC. Furthermore, the print sheet creating apparatus 1 is configured such that a predetermined image data is sent to the unit arranging portions 37 with the corresponding image forming units 40 and the binder toner transfer unit 50 disposed therein by the printer controller 84 and the printing unit 91. With this configuration, even in a case where the combination of each unit arranging portion 37 and the image forming unit 40 and the binder toner transfer unit 50 is changed, a desired print sheet can be formed. Therefore, the normal printing and the thermal transfer label printing both can be performed.
Furthermore, since the CPU 81 determines whether the combination of each unit arranging portion 37 and the image forming unit 40 and the binder toner transfer unit 50 is any one of the normal print mode α and the thermal transfer label creating mode β, it is possible to prevent a false printing caused by an arrangement error of the image forming unit 40 and the binder toner transfer unit 50 into each unit arranging portion 37. Further, the print sheet creating apparatus may be configured to stop its operation while informing the error using the host PC and the speaker/buzzer unit 95 and the display unit 89 in a case where an error is detected.
In addition, the intermediate transfer scheme may be applied by using the intermediate transfer roller 34 and the transfer belt 35.
As described above, with the print sheet creating apparatus and the print sheet creating method according to the invention, it is possible to perform both the thermal transfer label creating and the normal printing.
Further, the invention is not limited to the above embodiment. For example, the description in the above example has been made about a case where the normal print mode and the thermal transfer label creating mode are provided, but other modes may be provided. In addition, in the above example, the toners of yellow, magenta, and cyan are sequentially transferred onto the transfer belt, but the transfer may be performed in a different order. In this case, a plurality of combinations such as an order of magenta, yellow, and cyan, and an order of cyan, magenta and yellow may be considered.
In addition, the transfer may be performed using an image forming unit of a special color obtained by being specially mixed with red which is widely used in a point of purchase (POP) advertise field. In this case, a plurality of combinations such as a case where the specific color is used instead of magenta and a case where the specific color is transferred between the transfer of magenta and the transfer of yellow may be considered.
Furthermore, in the above example, only one type of the binder toner transfer unit is used in the label creating mode, but two or more types of the binder toner transfer units may be used. In addition, these binder toners may be colored.
In the above embodiment, the description has been made about the apparatus of the intermediate transfer scheme, but it is a matter of course that the invention is similarly applied to an apparatus of a direct transfer scheme. Furthermore, the type of printing medium in the sheet feeding portion is not fixed.
Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
