The printer of the present disclosure makes it possible to obtain a printed matter of high design quality.
The following describes an embodiment of the present disclosure (hereinafter referred to as “present embodiment”) with reference to the drawings.
The printer 100 of the present embodiment includes a transferee object sending unit 15, a transfer film sending unit 25, a printing device 300, a holding unit 60, a pasting unit 70, a cutting unit 80, and a control unit 90. The printing device 300 is situated downstream of the transfer film sending unit 25. The holding unit 60 is situated downstream of the transferee object sending unit 15 and the printing device 300. The pasting unit 70 is situated downstream of the holding unit 60. The cutting unit 80 is situated downstream of the pasting unit 70.
The transferee object sending unit 15 sends out a transferee object 10 downstream. The transferee object 10 of the present embodiment is a roll of printing paper. The transferee object sending unit 15 sends out the transferee object 10 downward by rotating in a direction (R1 direction) indicated by arrow R1 in
The transfer film sending unit 25 sends out the after-mentioned transfer film 20 downstream by rotating in a direction (R2 direction) indicated by arrow R2 in
As will be described later, the printing device 300 prints a transferred image onto the transfer film 20 by transferring inks of an ink ribbon 30 onto the transfer film 20.
The holding unit 60 holds the transferee object 10 and the transfer film 20 on top of each other so that a surface of the transfer film 20 on which the transferred image is printed faces the transferee object 10. Furthermore, the holding unit 60 sends out the transferee object 10 and the transfer film 20 downstream. The holding unit 60 of the present embodiment is configured to be able to send out the transferee object 10 and the transfer film 20 upstream as well as downstream so that the transferee object 10 and the transfer film 20 may be rewound.
It should be noted that the sending out of the transferee object 10 and the transfer film 20 by the holding unit 60, the sending out and rolling up of the transferee object 10 by the transferee object sending unit 15, and the sending out and rolling up of the transfer film 20 by the transfer film sending unit 25 are controlled so as to be synchronized with one another.
The holding unit 60 of the present embodiment includes two paired pinch rollers 61 and 62 placed opposite each other. The holding unit 60 holds the transferee object 10 and the transfer film 20 on top of each other between the two paired pinch rollers 61 and 62. Further, the holding unit 60 sends out the transferee object 10 and the transfer film 20 downstream or upstream by rotating the pinch rollers 61 and 62 while keeping holding the transferee object 10 and the transfer film 20.
The pinch rollers 61 and 62 assume a holding position (as indicated in
The pasting unit 70 pastes the transfer film 20 onto the transferee object 10 by pressing the transferee object 10 and the transfer film 20 against each other in the presence of the application of heat.
The pasting unit 70 of the present embodiment includes two paired heat rollers 71 and 72 placed opposite each other. The pasting unit 70 pastes the transfer film 20 onto the transferee object 10 by pressing the transferee object 10 and the transfer film 20 against each other in the presence of the application of heat while the transferee object 10 and the transfer film 20 are passing through the space between the two paired heat rollers 71 and 72.
The heat rollers 71 and 72 assume a pressing position (as indicated in
It should be noted that although, in the illustrated example, the pasting unit 70 includes the two paired heat rollers 71 and 72, the pasting unit 70 of the present disclosure may include a heat roller and a pressure roll that are placed opposite each other. Note, however, that from the point of view of performing sufficient heating even via a supporting layer 21 of the transfer film 20, it is preferable that the pasting unit 70 of the present disclosure include the two paired heat rollers 71 and 72.
As will be described later, the cutting unit 80 cuts off both ends of a pasted combination of the transferee object 10 and the transfer film 20 along a direction of conveyance of the transferee object 10, cutting the pasted combination of the transferee object 10 and the transfer film 20 along a direction orthogonal to the direction of conveyance of the transferee object 10, and then ejects the pasted combination of the transferee object 10 and the transfer film 20 as a printed matter 40 in the form of a sheet.
The control unit 90 controls the actions of the transferee object sending unit 15, the transfer film sending unit 25, the printing device 300, the holding unit 60, the pasting unit 70, and the cutting unit 80 by outputting control signals to driving units that separately drive each of these components.
The transfer film 20 includes a supporting layer 21 and a receptive layer 22 joined on top of the supporting layer 21.
The supporting layer 21 is a transparent layer, and appropriately supports the receptive layer 22 joined on top of the supporting layer 21. The supporting layer 21 is constituted, for example, by various types of resin having sufficient heat resistance and strength to withstand transfer.
The receptive layer 22 is a layer onto which inks of an ink ribbon 30 are transferred by the printing device 300. The receptive layer 22 is constituted, for example, by various types of resin that are capable of receiving the inks of the ink ribbon 30.
The ink ribbon 30 includes a supporting layer 31 and an ink layer 32 joined on top of the supporting layer 31.
The supporting layer 31 is a layer that supports inks of the ink layer 32 and, for example, is constituted by various types of resin film having sufficient heat resistance and strength to withstand transfer.
The ink layer 32 is constituted, for example, by a yellow layer (Y layer) 321, a magenta layer (M layer) 322, and a cyan layer (C layer) 323. The yellow layer (Y layer) 321 is constituted by an yellow ink. The magenta layer (M layer) 322 is constituted by a magenta ink. The cyan layer (C layer) 323 is constituted by a cyan ink. The yellow layer 321, the magenta layer 322, and the cyan layer 323 are periodically placed on top of the supporting layer 31 along a direction parallel with the length of the ink ribbon 30 (i.e. a direction in which the ink ribbon 30 extends). A color transferred image can be printed onto the receptive layer 22 of the transfer film 20 by transferring the inks of the yellow layer 321, the magenta layer 322, and the cyan layer 323 in sequence onto the receptive layer 22 of the transfer film 20.
The transfer onto the transfer film 20 of the inks of the yellow layer 321, the magenta layer 322, and the cyan layer 323 is herein referred to as “Y printing”, “M printing”, and “C printing”, respectively.
It should be noted that the aforementioned three types of ink are not the only inks that are used. Another colored ink may be used, or only one type only two types of ink, or four or more types of ink may be used.
The printing device 300 includes an ink ribbon sending unit 35, an ink ribbon rolling unit 36, a plurality of conveying rollers 37, a thermal head 38, and a platen roller 39.
The ink ribbon sending unit 35 sends out the ink ribbon 30 downward by rotating in a direction indicated by arrow R4 in
The thermal head 38 is placed between the ink ribbon sending unit 35 and the ink ribbon rolling unit 36 and, by heating the ink ribbon 30 from the side of the supporting layer 31 of the ink ribbon 30 while the ink ribbon 30 is being conveyed, transfers the inks of the ink layer 32 of the ink ribbon 30 onto the receptive layer 22 of the transfer film 20. The platen roller 39 is placed opposite the thermal head 38 across the ink ribbon 30 being conveyed and the transfer film 20 being conveyed, and supports the transfer film 20.
The thermal head 38 assumes an initial position (as indicated in
The initial position is a position in which the thermal head 38 is significantly away from the platen roller 39. When the thermal head 38 assumes the initial position, the ink ribbon 30 is easily detached from a body of the printer 100. The position in readiness for printing is a position in which the thermal head 38 is closer to the platen roller 39 than in the initial position. When the thermal head 38 assumes the position in readiness for printing, the thermal head 38 can quickly shift to the printing position, which is described next. The printing position is a position in which the thermal head 38 is in contact with the platen roller 39 across the ink ribbon 30 and the transfer film 20. When the thermal head 38 assumes the printing position, the inks of the ink layer 32 of the ink ribbon 30 can be easily transferred onto the receptive layer 22 of the transfer film 20.
The cutting unit 80 includes the first cutting unit 81 and the second cutting unit 82.
The first cutting unit 81 cuts off both ends of the pasted combination of the transferee object 10 and the transfer film along the direction of conveyance of the transferee object 10. By so doing, the first cutting unit 81 makes the lengths of the transferee object 10 and the transfer film 20 uniform in the direction orthogonal to the direction of conveyance of the transferee object 10.
The second cutting unit 82 cuts the pasted combination of the transferee object 10 and the transfer film 20 along the direction orthogonal to the direction of conveyance of the transferee object 10 after the pasted combination of the transferee object 10 and the transfer film 20 has been cut by the first cutting unit 81. By so doing, the second cutting unit 82 ejects the pasted combination of the transferee object 10 and the transfer film 20 as a printed matter 40 in the form of a sheet.
The first cutting unit 81 includes two cutters 811 and a cutter rest 812. The cutters 811 are configured as rotary cutters that rotate on an axis parallel to the direction orthogonal to the direction of conveyance of the transferee object 10. The two cutters 811 are placed slightly further inward than both ends, respectively, of the transferee object 10 being conveyed. The cutter rest 812 are constituted by a roller member that rotates on an axis parallel to the direction orthogonal to the direction of conveyance of the transferee object 10. As shown in
The second cutting unit 82 includes a cutter 821 and a cutter rest 822. The cutter 821 is configured as a rotary cutter that freely moves along the direction orthogonal to the direction of conveyance of the transferee object 10 and that rotates on an axis parallel to the direction of conveyance of the transferee object 10. The cutter rest 822 is configured as an elongated plate member that extends in the direction orthogonal to the direction of conveyance of the transferee object 10. As shown in
Next, a printed matter 40 that is obtained through the printer 100 of the present embodiment is described.
The printed matter 40 includes a transferee object 10 and a transfer film 20 joined on top of the transferee object 10. The transfer film 20 includes a transparent supporting layer 21 that transmits light and a receptive layer 22 on which a transferred image is printed. The receptive layer 22 of the transfer film 20 is located beside the transferee object 10.
Since the receptive layer 22 on which the transferred image is printed is located beside the transferee object 10, the transferred image printed on the receptive layer 22 is observed via the supporting layer 21. Therefore, the supporting layer 21 of the transfer film 20 needs to be transparent. The term “transparent” here needs only be to such an extent that the transferred image printed on the receptive layer 22 can be visually recognized. Further, the term “transparent” also encompasses “colored, transparent”.
Further, since the transferred image printed on the receptive layer 22 is observed via the supporting layer 21, the printed matter 40 is given deign quality that the supporting layer 21 of the transfer film 20 possesses. For example, in a case where the supporting layer 21 of the transfer film 20 is formed by a high-gloss transparent film, the printed matter 40 too has a high gloss. Thus, the printed matter 40 has high design quality.
It should be noted that the supporting layer 21 of the transfer film 20 is not limited to one formed by a high-gloss transparent film. The supporting layer 21 may for example be one having a matte or embossed outer surface or one having a design layer joined on top of an outer surface thereof.
Next, a method for controlling a printer 100 of the present embodiment is described.
The method for controlling a printer 100 includes a printing step (S2 to S7 of

The following describes an example of the method for controlling a printer 100.
In executing a printing process, the printer 100 first shifts from an initial state shown in
In the initial state, as shown in
Next, as shown in
The rewinding of the transfer film 20 is done by the pinch rollers 61 and 62 sending out the transfer film 20 upstream and the transfer film sending unit 25 rolling up the transfer film 20 by rotating in the −R2 direction. At this point in time, the transferee object 10 too is rewound as the transfer film 20 is rewound. The rewinding of the transferee object 10 is done by the pinch rollers 61 and 62 sending out the transferee object 10 upstream and the transferee object sending unit 15 rolling up the transferee object 10 by rotating in the −R1 direction. This rewinding of the transfer film 20 and the transferee object 10 is executed by the pinch rollers 61 and 62, the transfer film sending unit 25, and the transferee object sending unit 15 being driven in synchronization with one another.
Next, as shown in
Prior to the Y printing, the thermal head 38 shifts from the position in readiness for printing to the printing position. Then, the pinch rollers 61 and 62 send out the transferee object 10 and the transfer film 20 downstream by rotating in the R3 direction while keeping assuming the holding position. Accordingly, the transfer film 20 is rolled out from the transfer film sending unit 25, and the transfer film 20 thus rolled out is conveyed downstream. The printer 100 uses the thermal head 38 to execute the Y printing on the transfer film 20 being conveyed downstream.
Next, as shown in
Prior to this rewinding, the thermal head 38 shifts from the printing position to the position in readiness for printing. Then, the transfer film 20 and the transferee object 10 are rewound in a manner similar to the rewinding to the Y printing starting position.
Next, the printer 100 executes M printing on the transfer film 20 in a manner similar to the Y printing (S5 of
Next, in a manner similar to the rewinding to the M printing starting position, the printer 100 rewinds the transfer film 20 to a C printing starting position where C printing starts (S6 of

Next, the printer 100 pastes the transfer film 20 onto the transferee object 10 by pressing the transfer film 20 against the transferee object 10 in the presence of the application of heat (S8 of
Prior to this pasting of the transfer film 20 onto the transferee object 10, the heat rollers 71 and 72 shift from the stop-pressing position to the pressing position. Then, the heat rollers 71 and 72, which are in the pressing position, paste the transfer film 20 onto the transferee object 10 by pressing the transferee object 10 and the transfer film 20 against each other in the presence of the application of heat while the transferee object 10 and the transfer film 20 are being sent out by the pinch rollers 61 and 62.
Next, as shown in
Prior to this ejection of the printed matter 40, the thermal head 38 shifts from the printing position to the position in readiness for printing, and the heat rollers 71 and 72 shift from the pressing position to the stop-pressing position. The pinch rollers 61 and 62 send out the transferee object 10 and the transfer film 20 downstream by rotating in the R3 direction while keeping assuming the holding position. Accordingly, the pasted combination of the transferee object 10 and the transfer film 20 is conveyed downstream.
Finally, the printer 100 returns to the initial state shown in
Next, a method for manufacturing a printed matter 40 of the present embodiment is described.
The printed matter 40 is manufactured, for example, by controlling a printer 100 of the present embodiment by the aforementioned control method.
That is, the printed matter 40 is manufactured using a printer 100 including a transferee object sending unit 15, a transfer film sending unit 25, a printing device 300, a holding unit 60, and a pasting unit 70. Note here that the transferee object sending unit 15 is a unit configured to send out a transferee object 10 downward. The transfer film sending unit 25 is a unit configured to send out a transfer film 20 downstream. The printing device 300 is a unit situated downstream of the transfer film sending unit 25 and configured to print a transferred image onto the transfer film 20.

The pasting unit 70 is a unit situated downstream of the holding unit 60 and configured to paste the transfer film 20 onto the transferee object 10.
Moreover, the method for manufacturing a printed matter 40 includes a printing step (S2 to S7 of
The aforementioned printing step (S2 to S7 of
The aforementioned cutting step (S9 of
As described above, a printer 100 of the present embodiment includes a transferee object sending unit 15, a transfer film sending unit 25, a printing device 300 situated downstream of the transfer film sending unit 25, a holding unit 60 situated downstream of the transferee object sending unit 15 and the printing device 300, and a pasting unit 70 situated downstream of the holding unit 60.
