Description

  The present invention relates to a thermal transfer recording apparatus for recording an image by melting and transferring ink applied to an ink ribbon to a recording medium by driving a plurality of heating resistors provided in a recording head based on image information.

  In general, a recording apparatus having a function such as a printer, a copying machine, or a facsimile uses a recording head based on image information to record images (characters and symbols) on a recording sheet such as paper, cloth, plastic sheet, and OHP sheet as a recording medium. Etc.). There are a serial type and a line type as a scanning method in the recording apparatus. The serial type is a system in which an image is recorded while alternately repeating main scanning for moving the recording head along the recording sheet and sub-scanning for feeding the recording sheet at a predetermined pitch. The line type is a system in which an image is recorded only by feeding a recording sheet (sub-scan) while recording one line at a time. The recording apparatus can be classified into an ink jet type, a thermal transfer type, a laser beam type, a thermal type, a wire dot type, and the like depending on the recording type. A thermal transfer recording device (thermal transfer type recording device) drives a plurality of heating resistors provided in a recording head based on image information, thereby recording ink applied to an ink ribbon on recording paper, a plastic sheet or the like. An image is recorded by being melt-transferred onto the medium P.

  FIG. 10 is a side view showing a schematic configuration of a recording unit for recording (printing) an image on a recording medium in a conventional thermal transfer recording apparatus. In FIG. 10, the ink ribbon 102 and the recording medium P are pressed between the recording head (thermal head) 101 and the platen roller 103 while being overlapped. In this state, the recording medium P is sandwiched by a nip portion between a capstan roller 104 and a pinch roller 105 provided on the downstream side in the transport direction. On the other hand, the ink ribbon 102 is unwound from the supply reel 109, passes through the heating surface (heat generating portion) of the thermal head 101, and is then wound on the take-up reel 108. Thermal transfer recording is performed by driving the thermal head 101 while conveying a recording medium by a capstan roller 104 driven by a driving source (motor) (not shown). That is, the thermal transfer recording is performed by selectively driving (generating heat) a plurality of heating elements of the recording head (thermal head) 101 based on the image information to thermally transfer the ink on the ink ribbon onto the recording medium P. Is done.

  When printing of the first color is completed, the thermal head 101 is separated to perform printing of the next color, and in this state, the capstan roller 104 is rotated in the reverse direction to return the recording medium P to the printing start position. Then, the second and subsequent colors are printed by repeating the same operation as described above. The recording medium and the ink ribbon immediately after the thermal transfer recording are in a state in which the ink once melted and solidified adheres to both the recording medium and the ink ribbon, so that both are adhered. Therefore, the ink ribbon 102 is peeled from the recording medium by the peeling member 106 provided immediately downstream of the recording head 101. The peeling member 106 is formed with a peeling ridge line that is a bending point that is a starting point of peeling. By this peeling member, the ink ribbon is transported along a path branched from the transport path of the recording medium. That is, the peeled ink ribbon is taken up on the take-up reel 108, and the recording medium P that has been transferred and recorded is conveyed toward the paper discharge port by the capstan roller 104 and the pinch roller 105.

In order to realize stable and reliable ink ribbon conveyance, the peeling member 106 having the above function needs to satisfy several design requirements as follows.
First, the requirements for the material of the peeling member will be described. The peeling member receives a force due to the tension of the ink ribbon. However, if the peeling member is bent and deformed, there is a possibility that an image printed with wrinkles on the ink ribbon may be adversely affected. Therefore, the peeling member needs to have sufficient rigidity, and a metal is generally used as the material of the peeling member. At that time, in consideration of economy, it is common to employ a sheet metal member manufactured by press working.

  Next, the requirements for the method of processing the peeling member will be described. In order to bend the ink ribbon having a thickness of several microns, the peeling ridge line of the peeling member that becomes the bending point needs to have a smooth sliding property with respect to the ink ribbon. Therefore, in order to ensure smooth slidability in the peeling member which is a sheet metal member, conventionally, one of the following two processing methods has been adopted. The first processing method is a method of performing hemming bending on the peeling member. FIG. 11 is a side view showing a state in which the ink ribbon 102 is bent by the peeling member 106 having a ridge line formed by hemming bending. As shown in FIG. 11, by sliding the ink ribbon 102 along the ridge line of the curved surface formed by hemming bending, printing can be performed on a recording medium without damaging the ink ribbon.

  The second processing method is a method of forming a peeling ridge line by using a broken surface of the fracture surface or a surface pressing of the fracture surface. Here, the sag surface is a curved surface formed at the cutting edge by punching. Further, the surface pressing means that a cutting edge obtained by punching is made to a smooth curved surface. FIG. 12 is a side view showing a state in which the ink ribbon 102 is bent by the peeling member 106 in which a ridge line is formed by using a sloping surface or surface pressing. As shown in FIG. 12, the ink ribbon is slid along the ridge line of the fracture surface of the fractured surface or the ridge line of the face-pressed curved surface, and the ink ribbon is not damaged as in the case of the hemming bending process. It can be printed on a recording medium.

  Finally, the requirements for the curved shape in the longitudinal direction of the peeling member will be described. By forming the peeling ridge line of the peeling member into a curved shape in which the central portion in the width direction of the ink ribbon swells, the ink ribbon of several microns is conveyed while being extended outward from the central portion. The effect of the curved shape of the peeling member is disclosed in Patent Document 1, for example. Also by this curved shape effect, the wrinkling of the ink ribbon can be prevented or suppressed, and printing can be performed in a good state without damaging the recording medium such as recording paper. FIG. 13 is a plan view showing a state in which the peeling member 106 having a curved peeling ridge line is attached to the thermal head 101. 14 is a longitudinal sectional view taken along line 14-14 in FIG. 15 is a front view as seen from line 15-15 in FIG.

13 to 15, the degree of bending is exaggerated for easy understanding of the bending shape. As shown in the figure, the peeling ridgeline that is the bending point of the peeling member 106 is provided with a curved shape in two directions, the horizontal direction and the vertical direction, but this may be a curved shape in any one direction. The curved shape in the horizontal direction is a curved shape in which the central portion is convex in the printing progress direction as shown in FIG. Further, the curved shape in the vertical direction is a curved shape in which the central portion is convex in a substantially vertical direction toward the print surface (print surface) as shown in FIG.

  FIG. 16 is a plan view showing a state in which the bending member 106 is attached to the thermal head 101 in the case where the peeling ridge line curved in the two directions is provided on the peeling member manufactured by the above-described hemming bending process. 17 is a longitudinal sectional view taken along line 17-17 in FIG. FIG. 18 is a front view as seen from line 18-18 in FIG. 16 to 18, the peeling member 106 having a curved peeling ridge line is attached to the thermal head 101 via a spacer 107. However, when the ridge line of the peeling member processed by hemming bending is provided with a curve, there is an inconvenience that it is difficult to provide the curve in two directions.

  That is, although it is possible to provide a horizontal curve as shown in FIG. 16 by plastic working called hemming bending, it is difficult to provide a vertical (downward) curve as shown by a two-dot chain line in FIG. There is an inconvenience. Further, although it is possible to provide a horizontal curve as shown in FIG. 16, there is a disadvantage that the processing accuracy is low and the dimensional stability in mass production is low because the processing uses plastic deformation. Therefore, when hemming bending is employed, it is common to provide only a curve in the conveying direction as shown in FIG. 16 while allowing low dimensional accuracy. 16 to 18, the degree of bending is exaggerated for easy understanding of the bending shape.

  FIG. 19 shows a state in which the bending member 106 is attached to the thermal head 101 when the peeling ridge line curved in the above-mentioned two directions is provided on the peeling member formed by using the above-described fracture surface or surface pressing. FIG. 20 is a longitudinal sectional view taken along line 20-20 in FIG. FIG. 21 is a front view as seen from line 21-21 in FIG. 19 to 21, also in this case, the peeling member 106 having a curved peeling ridge line is attached to the thermal head 101 via the spacer 107. When forming a flared surface or a ridge line subjected to surface pressing by pressing, it is easy to provide a curve in the vertical direction (direction toward the printing surface) as shown in FIG. For this reason, it can be expected to maintain the processing accuracy and to secure the dimensional stability in mass production.

  On the other hand, it is possible to provide the bending in the printing direction (horizontal direction) as shown in FIG. However, since the processing uses plastic deformation, there are disadvantages in that processing accuracy is low and dimensional stability in mass production is also low. Therefore, in this case, it is common to provide only a curve in the direction toward the printing surface as shown in FIG. In FIGS. 19 to 21, the degree of bending is exaggerated for easy understanding of the curved shape.

  The present invention has been made in view of the above technical problems. SUMMARY OF THE INVENTION An object of the present invention is to provide a thermal transfer recording apparatus provided with a peeling member capable of giving a curved shape to a peeling ridge line which is a bending point of an ink ribbon in a direction in which a recording medium is conveyed and a direction toward a printing surface. is there. And it is providing the thermal transfer recording apparatus provided with the peeling member which can maintain the high dimensional accuracy of a peeling ridgeline, and the dimensional stability in mass production.

  The thermal transfer recording apparatus of the present invention drives a plurality of heating resistors provided in a recording head based on image information, thereby thermally transferring the ink applied to the ink ribbon to a recording medium to record an image. The recording apparatus includes a peeling member attached downstream of the thermal head in the recording medium conveyance direction for peeling the ink ribbon from the recording medium. The peeling member includes an attachment surface that can be attached to the thermal head, and a width of the ink ribbon. The leading edge that extends in the direction has a peeling surface that becomes a peeling ridge line that bends the ink ribbon, and the mounting surface is attached to the thermal head, and the peeling surface is inclined with respect to the direction of transporting the recording medium The leading edge of the peeling surface is formed in a curved shape in which the intermediate portion in the width direction of the ink ribbon is convex.

  According to the present invention, there is provided a thermal transfer recording apparatus provided with a peeling member capable of giving a curved shape to a peeling ridge line serving as a bending point of an ink ribbon in a direction in which a recording medium is conveyed and a direction toward a printing surface. Accordingly, a thermal transfer recording apparatus including a peeling member capable of maintaining high dimensional accuracy of the peeling ridge line and dimensional stability in mass production is provided. As a result, it is possible to provide a thermal transfer recording apparatus that can eliminate damage such as wrinkling in the ink ribbon and can stably transport the ink ribbon.

  Embodiments of the present invention will be specifically described below with reference to the drawings. Note that the same reference numerals denote the same or corresponding parts throughout the drawings. FIG. 1 is a longitudinal sectional view showing a configuration of a main part of an embodiment of a thermal transfer recording apparatus according to the present invention. In FIG. 1, a plurality of heating resistors are arranged on the surface (the lower surface in the figure) facing the ink ribbon 2 of the recording head (thermal head) 1. The plurality of heating resistors are selectively driven (pulse energization) based on image information, whereby the ink applied to the ink ribbon 2 is melted and transferred to the recording medium P to record an image. Yes. In this thermal transfer recording apparatus, an ink ribbon 2 supplied from a supply reel 9 is joined to a recording medium P fed from a recording medium stacking unit (not shown), and the superimposed recording medium and ink ribbon are connected to a recording head. 1 and the platen roller 3 are pressed.

  The ink ribbon is overlaid on the printing surface (recording head side surface) of the recording medium P in the region of the heat generating surface of the recording head 1. The recording medium is sandwiched between nip portions of a capstan roller 4 and a pinch roller 5 provided on the downstream side in the transport direction of the thermal head (recording head) 1. The recording medium is conveyed between the thermal head 1 and the platen roller 3 by rotationally driving the capstan roller 4 with a driving source (motor) (not shown). The recording medium P is not particularly limited as long as it is a sheet that can record an image by melting and transferring ink, such as recording paper or a plastic sheet. it can.

  On the other hand, the ink ribbon 2 unwound from the supply reel 9 joins the recording medium P on the upstream side of the thermal head 1, and is transported together with the recording medium between the thermal head and the platen roller 3, and then downstream of the thermal head. Is peeled off from the recording medium by the peeling member 6. The peeled ink ribbon is taken up by the take-up reel 8. In thermal transfer recording, the ink on the ink ribbon 2 is melt-transferred onto the recording medium P by selectively driving (generating heat) a plurality of heating elements of the recording head (thermal head) 1 based on image information. Is done. When printing of the first color is completed, the thermal head 1 is separated to perform printing of the next color, and in this state, the capstan roller 4 is rotated in the reverse direction to return the recording medium to the printing start position. Then, the second and subsequent colors are printed by repeating the same operation as described above.

  The recording medium P and the ink ribbon 2 immediately after the thermal transfer recording are in a state in which they are adhered because the ink once melted and solidified adheres to both the recording medium and the ink ribbon. Therefore, the ink ribbon is peeled from the recording medium by the peeling member 6 provided immediately downstream of the thermal head 1. The peeled ink ribbon is taken up on the take-up reel 8. On the other hand, the recording medium which has been transferred and recorded and the ink ribbon is peeled off is conveyed toward the paper discharge port by the capstan roller 4 and the pinch roller 5. The peeling member 6 is formed with a peeling ridge line 6b serving as a bending point that is a starting point of peeling.

  FIG. 2 is a plan view showing a state in which the peeling member in the thermal transfer recording apparatus of FIG. 1 is attached to the thermal head. FIG. 3 is a longitudinal sectional view taken along line 3-3 in FIG. FIG. 4 is a front view of the peeling member as seen from line 4-4 in FIG. 5 is an arrow view of the peeling member in FIG. 2 as seen from a direction perpendicular to the peeling surface along line 5-5 in FIG. 2 to 5, a peeling member 6 made of a pressed sheet metal member is attached to the downstream surface of the thermal head 1 in the recording medium conveyance direction. The peeling member 6 includes an attachment surface 6a that can be attached in a surface contact state to a surface downstream of the thermal head 1 in the conveyance direction (a surface that is substantially vertical in the illustrated example), and the ink ribbon 2 parallel to the width direction of the ink ribbon. And a peeling surface 6c having a peeling ridge line 6b serving as a bending point that is a peeling starting point.

  As shown in the drawing, the peeling surface 6c is bent ridgeline (viewed from the side surface) so as to be inclined in both directions of conveying the recording medium and in the direction toward the printing surface (printing surface) of the recording medium, as shown in the figure. Bending point) It is bent along 6d. In the present embodiment, the conveyance direction of the recording medium is set to a substantially horizontal direction, and the direction toward the printing surface is set to a substantially vertical surface (a surface in the vertical direction). The bending angle θ between the attachment surface 6a and the peeling surface 6c in the bending ridge line 6d is selected to be 90 degrees or more and less than 180 degrees. The peeling member 6 is a sheet metal member obtained by pressing a sheet metal, and the leading edge of the peeling surface 6 c is formed in a curved shape in which the intermediate portion in the width direction of the ink ribbon 2 is convex. The leading edge is formed by a cutting edge formed by punching. And the peeling ridgeline 6b used as the bending point of the ink ribbon 2 is formed by the ridgeline by the side of the cutting edge of the cutting edge by press work. This beveled surface is a curved surface formed at the cutting edge by punching.

  FIG. 9 is a partial vertical cross-sectional view showing a drooping surface (curved surface) formed at a cutting edge by punching (pressing). In FIG. 9, when a sheet metal set on the upper surface of the die is punched by punching, a drooping surface and a flash are formed at the cutting edge of the punched sheet metal (sheet metal member). A drooping surface made of a curved surface is formed on the punch driving side on the upper surface side in the figure. On the other hand, a flash is formed on the lower side (outside side) of the cutting edge. In FIG. 9, the sizes of the flash and the raft surface are exaggerated and are actually several tens of microns. In the present embodiment, the peeling ridge line 6b at the tip edge of the peeling surface 6c is formed by a curved surface formed of a curved surface formed at a cutting edge by stamping as shown in FIG. However, if there are irregularities on the flank surface, or if the edge where the burr has occurred is used as a peeling ridge line, a smooth curved surface is formed by applying surface pressing to make the edge a smooth surface. May be.

  Further, since the peeling surface 6c is a downward inclined surface, the curved shape of the peeling ridge line 6b is the center when viewed from either one of the two directions of the direction of transporting the recording medium P and the direction of the recording medium. The part is curved so as to be convex. In the present embodiment, as illustrated, the direction parallel to the direction in which the recording medium P is conveyed is set to a substantially horizontal direction, and the direction perpendicular to the printing surface of the recording medium is set to a substantially vertical direction. ing. 2 to 5, the degree of curvature of the peeling ridge line 6b is exaggerated for easy understanding of the curved shape.

  The peeling member 6 according to the present embodiment described with reference to FIGS. 2 to 5 includes a mounting surface 6a that can be attached to the thermal head 1, and a peeling ridge line 6b whose leading edge extending in the width direction of the ink ribbon 2 bends the ink ribbon. And a peeling surface 6c. Then, with the attachment surface 6a attached to the thermal head, the peeling surface 6c is inclined with respect to both the direction of transporting the recording medium P and the direction toward the printing surface. Therefore, the following significant advantages (effects) can be obtained as compared with the conventional peeling member. First, as a first advantage, the curved shape of the peeling ridge line 6b (the shape in which the intermediate portion in the width direction of the ink ribbon is convex) can be easily processed with high dimensional accuracy in both shapes seen from two directions. In addition, the dimensional stability in mass production can be maintained at a high level.

  That is, since the peeling member 6 is manufactured by press working, a curved shape can be punched from a direction perpendicular to the peeling surface 6c as indicated by the arrow in FIG. For this reason, when processing the curved shape of the peeling ridge line 6b (curved shape in which the intermediate portion in the width direction of the ink ribbon is convex), it is much easier and easier than processing the conventional curved shape by plastic deformation. It can be created with dimensional accuracy and high mass production stability. As a result, a curved shape in a direction parallel to the direction in which the recording medium P is conveyed and a curved shape in a direction perpendicular to the printing surface of the recording medium can be formed while ensuring high dimensional accuracy and high mass production stability. it can.

  As a second advantage, the thermal head 1 that is a recording head can be downsized. That is, the region indicated by the oblique line C in FIG. 3, that is, the region above the peeling surface 6c, is a portion generally formed of a metal material such as aluminum in order to ensure rigidity, heat resistance and thermal conductivity in the conventional structure. It is. According to the present embodiment, as shown in the drawing, the bent-shaped peeling member 6 is attached to the recording head 1 on the upstream side in the recording medium conveyance direction from the peeling ridge line 6b, so that a space is formed above the peeling member 6. Therefore, the thermal head can be downsized by the volume of this portion, and the cost can be reduced by downsizing. Further, it is necessary to dispose a ribbon guide or a member such as a sensor for detecting a leading marker of each color of the ribbon in the passing range of the ink ribbon 2. Parts such as a ribbon guide and a sensor can be moved from the previous mounting position to the empty space C. Therefore, by moving these parts to the above-mentioned space C, the great advantage that the entire apparatus can be reduced in size can be obtained.

  As a third advantage, the peeling ridge line 6b formed by the curved surface of the bent edge of the sheet metal material or the curved surface formed by surface pressing can be performed only on one side of the sheet metal member. In the conventional configuration shown in FIGS. 19 to 21, there is a possibility that the ink ribbon may come into contact with both sides of the broken edge. Therefore, in order to prevent damage to the ink ribbon, it is highly necessary to make both sides smooth edge surfaces. On the other hand, in the peeling member 6 according to the present embodiment, as shown in FIG. 3, the edge surface with which the ink ribbon contacts is limited to one side. Therefore, in order to prevent damage to the ink ribbon, the peeling ridge line 6b formed on the flared edge surface or the surface pressing processed surface only needs to be provided on one side. That is, according to this embodiment, the number of processing steps of the peeling member 6 can be reduced, and a large merit in mass production can be obtained.

Also in this embodiment, as the angle θ between the attachment surface 6a and the peeling surface 6c approaches 180 degrees, the ink ribbon may come into contact with both sides of the break edge. For this reason, in the present embodiment, the third advantage described above may be diluted in some cases.
Moreover, in FIGS. 2-5, the peeling member 6 is exaggerated and drawn in order to make an understanding about a shape etc. easy. The actual peeling member has a very large aspect ratio and is an elongated part. For example, in an example of an A6 size printing apparatus, the length in the longitudinal direction is 100 mm or more, whereas the length in the short direction is about 10 mm.

  FIG. 6 is a plan view showing a configuration in which punch holes (or openings) 11 are provided at several locations on the bending ridge line 6d between the mounting surface 6a and the peeling surface 6c in the peeling member 6 in FIG. FIG. 7 is a longitudinal sectional view taken along line 7-7 in FIG. FIG. 8 is a front view as seen from line 8-8 in FIG. 6 to 8, punched holes (or openings) 11 are formed at several locations along the bending ridge line 6d between the attachment surface 6a of the peeling member 6 and the peeling surface 6c. These punched holes 11 are formed before the bending ridge line 6d is bent. Although the peeling member 6 shown in FIGS. 6-8 differs from the peeling member 6 shown in FIGS. 2-5 by the point which provides the punch hole 11, in other points, it has the substantially same structure. In addition, although the number of the punch holes (or openings) 11 on the bending ridge line 6d is usually formed at a plurality of places, it may be one place depending on circumstances. According to the peeling member shown in FIGS. 6-8, in addition to the effect similar to the peeling member of FIGS. 2-5, the following effects are acquired. That is, by forming the punched hole (or opening) 11 on the bending ridge line 6d in advance, it is possible to improve the workability and mass productivity when the bending ridge line of the peeling member 6 is pressed. It is done.

  According to the peeling member 6 according to the embodiment described above, the curved shape in the direction in which the recording medium is conveyed and the curved shape in the direction toward the printing surface of the recording medium can be simultaneously pressed (punched), and simultaneously high. Dimensional accuracy and high mass production stability can be guaranteed. In addition, space efficiency can be improved by downsizing the thermal head. Furthermore, it is possible to simplify the process when pressing the peeling member. As a result, damage such as wrinkles in the ink ribbon can be eliminated, and the ink ribbon can be stably conveyed, and a highly reliable high-quality thermal transfer recording apparatus can be provided. In addition, it is possible to provide a thermal transfer recording apparatus that is further reduced in size and price as compared with the prior art.
