<P>PROBLEM TO BE SOLVED: To prevent jamming of a sheet or deviation of a sheet from a conveyance path in a printer using a thick print sheet. <P>SOLUTION: A sheet bail device 31 with a rotary bail arm 37 is arranged on a conveyance path. The gear 44 of a shifter shaft contained in the sheet bail device is linked with the gear 45 of a sheet conveyance mechanism, and the shifter shaft switches the rotary bail arm 37 between a position directly under a printer head and a containing position in the sheet bail device depending on the conveyance direction of sheet. When the sheet is conveyed downstream, the rotary bail arm 37 projects above the conveyance path to prevent floating of the sheet. When the sheet is rewound and printed, the rotary bail arm 37 retreats in the sheet bail device from a position directly under the printer head and does not disturb print operation of the printer head. <P>COPYRIGHT: (C)2009,JPO&amp;INPIT

Description

  The present invention relates to a printer device that prints on a sheet wound in a roll shape, and more particularly to a printer device that prevents the sheet from floating.

  2. Description of the Related Art Printer apparatuses that perform multicolor thermal transfer printing on roll-shaped resin sheets and paper, and printer apparatuses that perform cutting processing and laminating processing together with printing are widely known. As an example, a plurality of thermal head units each having an ink ribbon of a different color are arranged in series on a flat sheet guide table at regular intervals, and a single color is printed for each thermal head while feeding the sheet linearly. There are some which perform printing and perform multicolor printing by passing a plurality of thermal heads (Patent Documents 1 and 2).

  The printer device of Patent Document 3 has a structure in which a plurality of thermal heads are arranged at regular intervals around a cylindrical sheet guide drum and can be made smaller overall than those of Patent Documents 1 and 2. ing.

In a page printer using cut sheets, a sheet is taken from a paper stock tray at the bottom of the apparatus by a pick-up roller, and is turned upside down from one end of the paper stock tray into a semicircular and reverse direction. In general, the paper is fed along the paper and discharged to the upper paper discharge tray (for example, Patent Document 4).

  A printer apparatus in which a plurality of printer heads or printer heads, a cutting processing unit, and the like are arranged on a flat sheet conveyance path has a large conveyance path, so that the size of the apparatus is increased. Although the length of the apparatus can be reduced if the conveyance path is curved as in the printer apparatus of Patent Document 3, a plurality of thermal head units are fixed around the sheet guide drum that is the conveyance path. Therefore, it is difficult to remove the paper when a paper jam or sheet jam occurs.

  Like a general page printer, if the sheet is turned upside down by a curved conveyance path and sent out, the length of the conveyance path can be reduced, and the surface of the conveyance path can be opened. However, in order to send a stiff print medium along a curved conveyance path, a pressing means for preventing the printing medium from floating up is necessary.

  Generally, as the pressing means, the edge of the sheet is pressed from above by angle-type sheet pressing parts provided on both side edges of the conveyance path, but normal printing such as an adhesive sheet with release paper is used. In the case of a sheet that is particularly stiffer than the paper, the sheet pressing part at the side edge may repel and escape from the sheet pressing part. Escape can be prevented by increasing the width of the sheet pressing portion, but since the area covered by the sheet pressing portion is increased, there is a disadvantage that the printing area in the width direction of the sheet becomes narrow.

  Therefore, there is a technical problem to be solved so that even a thick sheet can be stably fed without departing from the conveyance path, and the present invention solves the above problem. With the goal.

The present invention is to propose in order to achieve the above object, printing on the printing sheet wound into a roll, or have rows laminating process or cutting process in addition to printing, the printer head during printing A printer head lifting mechanism that lowers and contacts or approaches the printing sheet on the conveyance path and raises the printer head from the conveyance path when not printing, and a printing sheet that moves up to a position directly below the printer head when not printing and lifts the printing sheet And a sheet pressing unit that retracts from a position directly below the printer head during printing, the sheet pressing unit is provided in a sheet pressing device having a sheet pressing function disposed immediately before or after the printer head. The sheet pressing means receives power from a sheet conveying mechanism of the printer apparatus body, and Which provides a pressing position projecting directly under the printer head in conjunction with the conveying direction of the sheet conveying mechanism of the motor apparatus main body, the printer apparatus characterized by being configured to move to a position retracted into the sheet pressing apparatus It is.

  The sheet pressing device provided with the sheet pressing means provides a printer device formed so that one end side is hinged to the printer device main body and the other end is rotated to open the sheet conveyance path. .

  Further, the driving means of the sheet pressing means is constituted by a shifter shaft and an interlocking mechanism of the shifter shaft and the sheet pressing means, and a position for retracting the sheet pressing means to the sheet pressing device side according to the rotation direction of the shifter shaft; The present invention provides a printer apparatus configured to move to a pressing position protruding directly below the printer head.

  In addition, after the printing sheet is sent downstream, printing is performed by reversing the conveyance direction, power is transmitted from the sheet conveyance mechanism to the shifter shaft, and the sheet pressing means moves to the pressing position when the sheet is sent, A printer apparatus configured to be switched to a retracted position during reverse printing is provided.

  The present invention also provides a printer apparatus configured such that a torque limiter is interposed in the shifter shaft drive system of the printer apparatus so that the sheet conveying mechanism can continue the feeding operation regardless of the movable range of the sheet pressing means.

  Further, the amount of the printing sheet to be sent is equal to or longer than the length of the printing range plus the margin, and the sheet pressing means moves to the retracted position before the printing range returns to the position of the printer head when the conveyance direction is reversed. A printer apparatus configured as described above is provided.

  In the printer device of the present invention, when the printer head is not lowered onto the conveyance path, such as when the printing sheet is conveyed, the sheet pressing means advances to a position directly below the printer head and suppresses the lifting of the printing sheet. Even when a thick and stiff sheet such as an adhesive sheet with release paper is sent along a curved conveyance path, the sheet can be prevented from deviating from the conveyance path.

  Further, the sheet pressing means is provided in a sheet pressing device having a sheet pressing function disposed immediately before or after the printer head, and formed so that the sheet conveying path can be opened by rotating the sheet pressing device. Maintenance such as release processing can be performed easily.

  In addition, an independent drive mechanism is not required by driving power by transmitting power from the sheet conveying mechanism of the apparatus main body to the sheet pressing means.

  Further, in the configuration in which the sheet pressing unit opens and closes in conjunction with the rotation direction of the sheet conveying mechanism, the opening / closing switching unit is also unnecessary.

  Further, by providing a torque limiter in the drive system of the sheet pressing means, an on / off mechanism for power transmission becomes unnecessary.

The present invention, printing on the printing sheet wound into a roll, or have rows laminating process or cutting process in addition to printing, contact or approach to lowering the printer head to the printing sheet conveying path at the time of printing And a printer head lifting mechanism that lifts the printer head from the conveyance path during non-printing, and moves to a position directly below the printer head during non-printing to prevent the printing sheet from lifting, and retracts from the position directly under the printer head during printing. In the printer apparatus comprising the sheet pressing means, the sheet pressing means is provided in a sheet pressing apparatus having a sheet pressing function disposed immediately before or after the printer head, and the sheet pressing means is a sheet conveying mechanism of the printer apparatus main body. Power is transmitted from the printer and linked to the transport direction of the sheet transport mechanism of the printer body A pressing position projecting directly under the printer head Te, by constructing moves to a position retracted into the sheet pressing apparatus can send stably without departing from the even transport path a thick sheet The purpose of doing so was achieved.
In the present invention, the sheet pressing means to which power is transmitted from the sheet conveying mechanism moves to the pressing position and the retracted position in conjunction with the operation in the conveying direction of the sheet conveying mechanism. Accordingly, by forming the sheet pressing device so that the sheet conveying path can be opened by rotating the sheet pressing device, maintenance such as jam release processing can be easily performed. In addition, since the power is transmitted from the sheet conveying mechanism of the printer main body to the sheet pressing unit and driven, an independent driving mechanism for driving the sheet pressing unit is not required. Further, since the sheet pressing unit can be opened and closed in conjunction with the rotation direction of the sheet conveying mechanism, an opening / closing switching unit for the sheet pressing unit is unnecessary.

  FIG. 1 shows a printer device 1 that performs two-color printing, surface lamination processing and cutting processing on an adhesive sheet with release paper, the first printer unit 2 on the left side, the second printer unit 3 on the upper left side, and the upper surface Laminate processing part 4 is arranged on the right, and these three mechanism parts 2, 3, and 4 are hinged to the frame, respectively, and as shown in FIG. Can be exposed. In addition to the above configuration, each mechanism part 2, 3, 4 is hinged to the frame on one side in the width direction of the adhesive sheet with release paper, and the inner surface side is exposed by pulling up one end and inverting it. You may make it make it.

  FIG. 3 is a front view of the printer apparatus 1 with the front cover removed, and FIG. 4 is a simplified front view in which portions other than the main parts are not displayed. As shown in FIG. 4, the lower side of the center portion of the frame 5 is a sheet roll storage chamber 6, and the adhesive sheet roll SR with release paper attached to the sheet roll support shaft 7 is supported in the air. A first transport path 8 is arranged from the left to the top of the sheet roll storage chamber 6, and this first transport path 8 is a semicircular shape that reverses rightward from the left to the top of the sheet roll storage chamber 6. The reversing curved surface portion 8a and the non-reversing curved surface portion 8b extending horizontally from the upper end of the reversing curved surface portion 8a toward the right side of the frame 5, and below the first conveying path 8 are the first conveying path 8 and A second transport path 71 is arranged in parallel.

  The first conveyance path 8 has the apex of the motor-driven conveyance roller 9 and the driven guide roller 10 exposed from the inner surface side through slits formed at important points, and is counted from the entrance on the sheet roll housing chamber 6 side. The second roller is a grid roller 11 in which the surface of a hard material such as metal or ceramic is subjected to anti-slip processing, and in the printing process described later, the feeding amount of the adhesive sheet with release paper is precisely controlled by the grid roller 11. It is configured.

  A pinch roller 12 is elastically in contact with the motor-driven transport roller 9, and the pinch roller 12 facing the grid roller 11 is supported by a cam-driven link (not shown), and other than the printing process. In this feeding process, it is separated from the grid roller 11 and is controlled so as to elastically contact the grid roller 11 only by the printing process by the control unit. That is, the conveyance roller 9 and the pinch roller 12 sandwich the release sheet-attached adhesive sheet S and feed it in the forward direction (downstream from the release sheet-attached adhesive sheet roll SR). During printing, the conveyance roller 9 and the grid roller 11 and the pinch roller 12 And the adhesive sheet S with release paper is fed in the opposite direction across the adhesive sheet S with release paper.

  A shaft B in the vicinity of the sheet roller SR in FIG. 4 is rotatably fixed to the frame 5 by an arm C and is in contact with the sheet S. On the other hand, a sensor (not shown) is disposed in the vicinity of the arm C, and detects the angle of the arm C due to the contact between the shaft B and the sheet S. By controlling the rotation of the sheet roll SR according to this detection angle, in cooperation with the shaft B, the sheet S is given a moderate slack when the sheet S is fed, and the extra slack of the sheet S is absorbed when the sheet is rewound. By doing so, a constant amount of slack is always secured.

  A first printer unit 2 arranged in a vertical posture facing the left end of the inverted curved surface portion 8a of the first transport path 8, and a second printer unit 3 arranged in a horizontal posture facing the upper end of the inverted curved surface portion 8a. Have the same configuration, and a flat thermal head 14 is attached to a printer unit housing 13 that is a cradle for the ink ribbon roll IR. In the printing process, the thermal head 14 is illustrated by a cam mechanism (not shown). 4 moves from the floating position to the lowered position in contact with the guide roller 10 to perform thermal transfer printing on the surface of the pressure-sensitive adhesive sheet S with release paper. For example, two-color printing of black and red can be performed by attaching a black ink ribbon to the first printer unit 2 and attaching a red ink ribbon to the second printer unit 3.

  By disposing the thermal head 14 so as to face the inverted curved surface portion 8a of the first transport path 8, the lateral width of the apparatus can be suppressed as compared with a structure in which a plurality of thermal heads are disposed on the straight transport path, and a platen roller or a rib, etc. Therefore, it is not necessary to locally raise the sheet, so that satisfactory print quality can be obtained with the planar thermal head instead of the end face type thermal head, and there is no possibility of causing tunneling of the sheet floating from the release paper.

  The first printer unit 2 and the second printer unit 3 have a shaft hole 15 at the upstream end engaged with a shaft 16 provided in the main body frame 5, and are latched with a hook shape and a wedge shape as shown in FIG. 17 is fixed to the frame 5 in a closed state. By operating the latch 17 biased to the lock position by the spring in the unlocking direction, the first printer unit 2 and the second printer unit 3 can be opened by rotating about the shaft 16 as a fulcrum. The latch 17 is automatically engaged and fixed to a locking portion (not shown) of the frame 5.

  As shown in FIG. 4, a pair of front and rear open bearings 18 are formed on the left and right side surfaces of the printer housing 13, and the core of the ink ribbon roll IR is received by the open bearings. Gears are arranged in the vicinity of each of the pair of open bearings 18, the upstream side gear (the side near the sheet roll storage chamber) is the take-up gear 19, and the downstream side gear is the supply gear 20. 21 is connected to a gear G provided at the end of the core of the ink ribbon roll IR.

  A pair of front and rear intermediate gears 21 are attached to the tips of swing levers 22 coaxial with the shafts of the take-up gear 19 and the supply gear 20, respectively, and are stretched over the other ends of the two front and rear swing levers 22. Due to the spring force of the coil spring 23, the intermediate gear 21 is in elastic contact with the gear G at the end of the ink ribbon core. A torque limiter type brake (not shown) is connected to the shaft of the supply gear 20, and an appropriate back tension is applied to the ink ribbon when winding the ink ribbon.

  A link portion 22a extending in a direction approaching each other is formed at an intermediate portion between the two front and rear swing levers 22, and is a link attached to the side surface of the printer unit housing 13 by an axis A separately from the swing lever 22. A pin at the tip of the lever 24 engages with an elongated hole at the tip of the link portion 22a of the two swing levers 22 to constitute an interlocking link mechanism for the two swing levers 22.

  As shown in FIG. 4, when the first printer unit 2 and the second printer unit 3 are closed, the intermediate gear 21 is urged outward by the spring force of the tension coil spring 23, and the end of the core of the ink ribbon IR. The rear end of the link lever 24 is in contact with a first stopper pin 25 provided on the main body frame 5 and is prevented from rotating counterclockwise. That is, the intermediate gear 21 cannot move away from the gear G of the ink ribbon roll IR, and power is reliably transmitted from the take-up gear 19.

  On the other hand, in the state where the first printer unit 2 and the second printer unit 3 are rotated about the axis as shown in FIG. 5 and the surface on the thermal head side is exposed, the rear end of the link lever 24 is provided on the frame 5. The two swing levers 22 are rotated counterclockwise by hitting the two stopper pins 26, and the link lever 24 is rotated in the direction in which the intermediate gear 21 approaches against the spring force of the tension coil spring 23. As a result, the intermediate gear 21 is separated from the gear G of the ink ribbon roll IR, and the ink ribbon roll IR can be attached and detached.

  As shown in FIGS. 4 and 5, a sheet pressing device 31 is disposed immediately upstream of the first printer unit 2 and the second printer unit 3, respectively. As with the first printer unit 2 and the second printer unit 3, the sheet pressing device 31 is engaged with the frame 5 by the hinge shaft 32 and can rotate around the axis, and when a sheet jam or the like occurs. As shown in FIG. 5, the sheet is pulled up by exposing the inverted curved surface portion 8a of the first conveyance path 8.

  FIG. 6 shows a sheet pressing device 31, and two plates, an upstream pressing plate 34 (lower side in the figure) and a downstream pressing plate 35, are installed between the left and right side plates 33. , 35 have relative angles matched to the curved surface shape of the inverted curved surface portion 8a of the first transport path 8. A hinge shaft 32 that engages with the frame 5 passes through the lower portions of the left and right side plates 33, and the sheet pressing device 31 mounted on the frame 5 approaches the reversing curved surface portion 8a with the mounting shaft as a fulcrum. And can be rotated to the open position.

  In FIG. 6, a top plate 36 is installed above the upper downstream pressing plate 35 (in the depth direction of the paper) so as to face the downstream pressing plate 35, and a pair is placed on the left and right sides of the center of the top plate 36. The rotary presser arm 37 is attached in close proximity. A shifter shaft 38 is disposed between the top plate 36 and the downstream pressing plate 35, and the shifter shaft 38 engages with a pair of rotary pressing arms 37 to constitute an arm shift mechanism.

  7 and 8 show the operation of the arm shift mechanism. A channel-type bracket 39 (see FIG. 10 (a)) is attached to the center of the shifter shaft 38, and a link plate 41 is rotatably attached to a fixed shaft 40 installed on the bracket 39. . As shown in FIG. 7, the link plate 41 is formed with a pair of left and right elongated holes 42 in the lateral direction, and guide pins 43 provided at the rear end of the rotary pressing arm 37 are respectively connected to the link plate 41. It is engaged with the long hole 42 of.

  FIGS. 7 (a) and 8 (a) show a state in which the shifter shaft 38 is rotated clockwise in FIG. 8 (a), and the link plate 41 is linked to the right side (downstream side) by the pin. The rotary pressing arm 37 coupled to the plate 41 rotates in the direction in which the tip is separated from each other, and is housed between the downstream pressing plate 35 and the top plate 36.

  On the other hand, FIG. 7 (b) and FIG. 8 (b) show a state in which the shifter shaft 38 is rotated counterclockwise as opposed to FIG. 8 (a), and the link plate 41 moves to the left side (upstream side). As a result, the rotary pressing arm 37 rotates in the direction in which the tips approach each other and protrudes downstream of the sheet pressing device 31. 9 and 10 show the retracted state and the protruding state of the rotary pressing arm 37, respectively. FIG. 10 is a view in which the top plate 36 of the sheet pressing device 31 is removed from FIG. 9 and the fulcrum portion of the rotary pressing arm 37 is exposed.

  A gear 44 is attached to the end of the shifter shaft 38. As shown in FIG. 11, the gear 45 of the sheet conveying drive system in the frame 5 of the printer device 1 and the gear 44 of the sheet pressing device 31 are engaged with each other. Power is transmitted to the shifter shaft 38. A torque limiter (not shown) is interposed on the shaft of the gear 45 of the sheet conveyance drive system, and after the rotary pressing arm 37 reaches the storage position or the protruding position, the gear 45 of the sheet conveyance drive system Prevents the sheet pressing device 31 from obstructing the sheet conveyance.

  12 to 15 show a state in which the first printer unit 2, the second printer unit 3, and the laminating unit 4 are removed from the printer device 1. FIG. 12 shows a standby state in which the sheet pressing device 31 is closed. Is a state in which the sheet pressing device 31 is opened. FIG. 14 shows a state in which the rotary pressing arm 37 of the sheet pressing device 31 is housed, and FIG. 15 shows a state in which the rotary pressing arm 37 protrudes in the downstream direction.

  Next, the other parts will be described with reference to FIG. The laminating section 4 disposed in the upper right part of the main body is a unit that presses the laminating sheet L onto the surface of the adhesive sheet S with release paper printed by the printer units 2 and 3 using the laminate sheet roll LR with release paper. In addition, instead of the thermal head 14 of the printer units 2 and 3, a pressure roller 27 that moves up and down by a cam mechanism is provided, and the rotation direction when opening and closing is opposite to that of the first printer unit 2 and the second printer unit 3. Also, since the winding diameter of the laminate sheet roll LR with release paper is large, the number of intermediate gears is larger than that of the intermediate gear 21 of the printer units 2 and 3, and the basic configuration is the same as that of the first printer unit 2 and the second printer unit 3. Due to the same structure, the tension coil spring 23 'and the link mechanism similar to those of the printer units 2 and 3, the intermediate gear 21' is separated from the core gear G of the laminate sheet roll LR with release paper when opened, and the intermediate gear when closed. 21 'elastically contacts the gear G of the laminate sheet roll LR with release paper.

  The laminate sheet with release paper comprises a first adhesive layer a, a laminate film layer b, a second adhesive layer c, and a release paper layer d as shown in FIG. The force is set so as to be larger than the adhesive force of the second adhesive layer c. For this reason, when the laminate sheet with release paper and the adhesive sheet S with release paper pulled out from the laminate sheet roll LR with release paper pass through the pressure roller 27 in a laminated state, the first adhesive layer a and the laminate film layer b Only the laminate sheet L made of is adhered to the surface of the pressure-sensitive adhesive sheet S with release paper, and only the release paper is wound on the winding roller as shown in FIG.

  A cutter blade 28 for cutting the laminate sheet L is disposed slightly downstream of the guide roller 10 of the first conveyance path 8 facing the pressure roller 27 of the laminating unit 4, and the cutter blade is used during the laminating process. 28 is driven obliquely downward toward the upstream direction of the first conveying path 8 to cut the end portion of the laminate sheet L attached to the surface of the adhesive sheet S with release paper.

  A path switching flap 51 is provided immediately after the cutter blade arrangement position of the first conveyance path 8, and a cutting processing unit 61 is disposed on the lower right side of the path switching flap 51. Further, the right end of the second conveyance path 71 disposed below the first conveyance path 8 faces the path switching flap 51.

  The path switching flap 51 switches the path of the release sheet-attached adhesive sheet S sent on the first transport path 8 to the end direction of the first transport path 8 or the cutting processing unit 61 direction. 4), the horizontal position in FIGS. 4 and 8 and the position rotated clockwise by a certain angle are switched.

  The route switching flap 51 has three layers of upper, middle, and lower seat passages 53, 54, and 55 formed therein. The upper seat passage 53 and the lower seat passage 55 are horizontal, and the middle seat passage 54 is inclined downwardly to the right. The middle sheet path 54 and the lower sheet path 55 are respectively expanded on the side that becomes the entrance of the adhesive sheet S with release paper, that is, the left side in the middle sheet path 54 and the right side in the lower sheet path 55. Thus, the adhesive sheet S with release paper can be reliably introduced.

  Immediately after the path switching flap 51, a motor-driven ridge 56 is arranged, and when the printed adhesive sheet with release paper S is sent to the cutting processing section through the middle sheet path 54 of the path switching flap 51, The pressure-sensitive adhesive sheet S with release paper is cut at the end of the printing range of the pressure-sensitive adhesive sheet S with release paper.

  The cutting processing unit 61 has the same configuration as a normal cutting plotter and includes a cutting head 62 that is controlled to move in the width direction of the sheet. Based on the cutting data, the cutting processing unit 61 removes the adhesive sheet S with release paper by a feeding mechanism by the grid roller 63. While moving in both the front and rear directions, the cutting head 62 is driven in the sheet width direction to cut only the pressure-sensitive adhesive sheet of the pressure-sensitive adhesive sheet S with release paper according to the cutting data.

  Next, a series of operations of the printer apparatus 1 having the above configuration will be described. First, as shown in FIG. 4, when the tip of the release sheet adhesive sheet S of the release sheet roll SR is inserted into the entrance of the first transport path 8, the first sheet sensor 29 disposed at the entrance detects the insertion of the sheet. Then, the motor of the feeding mechanism is started, the sheet is sandwiched and pulled by the conveying roller 9 and the pinch roller 12, and is fed upward along the first conveying path 8 as shown in FIG. At this time, the pinch roller 12 facing the grid roller 11 that is the second conveying roller from the entrance is floating, and the sheet is fed by the conveying roller 9 excluding the grid roller 11. When the conveyance roller 9 starts to rotate in the direction from upstream to downstream, the shifter shaft 38 of the sheet pressing device 31 is driven to rotate counterclockwise as shown in FIG. Protrudes in the downstream direction of the conveyance path and presses the surface of the adhesive sheet S with release paper immediately below the first printer unit 2 and the second printer unit 3 to prevent lifting.

  As shown in FIG. 16, when the leading edge of the adhesive sheet S with release paper reaches the position of the second sheet sensor 30 disposed immediately before the pressure roller 27 of the laminating unit 4, the second sheet sensor 30 The feed is stopped by the detection signal, and thereafter, as shown in FIG. 17, the pinch roller 12 facing the grid roller 11 is brought into elastic contact with the grid roller 11 to sandwich the adhesive sheet S with release paper.

  Since the conveyance path length from the position of the second sheet sensor 30 to the position of the thermal head 14 of the second printer unit 3 is known, the grid roller 11 is driven to move the sheet downstream according to the sheet length data to be printed. Send or rewind upstream. FIG. 18 shows an example in which an adhesive sheet with release paper is sent downstream.

  Then, when the starting point of the printing range (including the margin) on the adhesive sheet with release paper is located directly below the thermal head 14 of the second printer unit 3, as shown in FIG. 19, the adhesive sheet with release paper Enter the printing process while rewinding S. When the conveyance roller 9 starts to rotate in the direction from the downstream to the upstream, the shifter shaft 38 of the sheet pressing device 31 is driven to rotate clockwise as shown in FIG. The sheet is retracted from directly below the first printer unit 2 and the second printer unit 3 and stored in the sheet pressing device 31. When the first printer unit 2 with the black ink ribbon and the second printer unit 3 with the red ink ribbon are controlled by the print control unit based on the print data, respectively, when the print area reaches directly below the thermal head 14. Then, the thermal head 14 is lowered and the thermal head 14 is pressed against the sheet surface to perform printing.

  As described above, the sheet is conveyed along a guide (not shown) in the sheet width direction before the sheet is sandwiched between the grid roller 11 and the pinch roller 12, thereby ensuring the straightness of the sheet. And since printing is performed while rewinding the sheet while maintaining straightness, compared with a configuration in which printing is performed while the sheet is pulled out directly from the sheet roll SR by the grid roller, the vertical skew due to the skew of the sheet and the accumulation of the directional displacement is reduced. The possibility of occurrence and sheet clogging is greatly reduced.

  The first printer unit 2 and the second printer unit 3 raise the thermal head 14 when printing is completed, stop sheet rewinding when all printing processes are completed, After the pinch roller 12 in contact with the grid roller 11 is lifted and the restraint of the sheet by the grid roller 11 is released, the adhesive sheet S with release paper is sent downstream. 16 and 17, when the leading edge of the adhesive sheet S with release paper is detected again by the second sheet sensor 30, the pinch roller 12 facing the grid roller 11 is elastically contacted with the grid roller 11. Then, the pressure-sensitive adhesive sheet with release paper S is sandwiched, and the tip of the pressure-sensitive adhesive sheet with release paper S is sent from here to the end of the transport roller 9 next to the second sheet sensor 30.

  This is the end of the description of the printing process. The following is a description of the laminating process and the cutting process. As shown in FIG. 20, when the adhesive sheet S with release paper is sent, the laminating section 4 moves down the pressure roller 27 of the laminate processing section 4 and ends the lamination range of the adhesive sheet S with release paper. Until the pressure reaches the pressure roller position, the adhesive sheet S with release paper is sent downstream, and the laminate sheet is pressure-bonded to the surface of the printed adhesive sheet with release paper S. The leading end portion of the release sheet-attached pressure-sensitive adhesive sheet S passes through the horizontal upper sheet path 53 of the path switching flap 51 and is sent out from the right end of the first transport path 8.

  After completion of the laminating process, the pressure roller 27 of the laminating unit 4 is raised, and as shown in FIG. 21, the cutter blade 28 is driven obliquely downward in the upstream direction of the first conveying path 8, and the pressure-sensitive adhesive sheet with release paper S The end portion of the laminate sheet L attached to the surface of the sheet is cut.

  Next, reverse the sheet feeding direction, as shown in FIG. 22, rewind until the leading edge of the adhesive sheet S with release paper passes the path switching flap 51, rotate the path switching flap 51 clockwise, The entrance on the upstream side of the sheet passage 54 is lifted and opposed to the first conveyance path 8. Then, the feeding direction of the feeding mechanism is reversed again, and the adhesive sheet with release paper S is sent downstream.

  As shown in FIG. 23, the release sheet-attached adhesive sheet S passes through the middle sheet passage 54 of the path switching flap 51 and moves to the lower right and is sent to the cutting processing unit 61. When the end of the printing range of the sheet based on the print data reaches the position of 鋏 56, the sheet feeding is stopped, and the pinch roller 12 facing the grid roller 63 of the cutting processing unit 61 is lowered to adhere the release paper While sandwiching the sheet S, the tack 56 is driven to cut the adhesive sheet S with release paper.

  Subsequently, the sheet feeding direction is reversed, and as shown in FIG. 24, rewinding is performed until the leading end of the adhesive sheet S with release paper passes the path switching flap 51, and the path switching flap 51 is rotated counterclockwise. Return to the initial position. At this time, the rear end of the adhesive sheet S with release paper that has been cut and remained on the cutting processing unit 61 faces the entrance of the lower sheet passage 55 of the path switching flap 51, and as shown in FIG.
