DETAILED DESCRIPTION OF THE INVENTION
  Next, embodiments of the invention will be described.
[0011]
  [Printer configuration]
  First, the schematic structure of the printer 1 as a thermal recording apparatus will be described with reference to FIGS.
  1 is a perspective view of the printer, and FIG. 2 is a side sectional view. FIG. 3 is a perspective view showing a state in which the lid is opened. FIG. 4 is a side cross-sectional view showing a state in which the paper is set in the paper storage unit. FIG. 5 is an enlarged cross-sectional view showing details of the paper separating unit and the printing mechanism unit.
[0012]
  As shown in FIG. 1, the printer 1 has a rectangular configuration in a plan view (size that can accommodate paper of A6 to A7 size) and has a compact configuration with a thickness of about 2 cm or less. ing.
  The main body case 2 of the printer 1 is formed by covering the lower surface of the frame 3 with the lower cover 4 and partially covering the upper surface with the upper cover 5.
[0013]
  In the remaining portion of the upper surface side of the frame 3 except for the portion covered with the upper cover 5, a paper storage portion (paper feeding portion) 6 is formed as shown in FIG. In this paper storage section 6, a paper package 9 in which a plurality of A6 to A7 size cut sheet-like thermal paper (printed medium; hereinafter referred to as "paper") 7 is stored in a package material 8 is shown in FIG. It can be accommodated as shown in
  The upper portion of the paper storage unit 6 is covered with a lid 10, and the lid 10 is rotatable as shown by the arrow in FIG. FIG. 3 shows a state where the lid 10 is opened. A lock mechanism (not shown) is provided on the main body case 2 side so that the lid 10 can be closed and locked as shown in FIG. 4 in a state where the paper package 9 is set in the paper container 6 as described above. It has become.
[0014]
  A pickup roller 12 as a paper separating unit 11, a separation block 13, and the like are disposed at one end of the paper storage unit 6. Also, below the upper cover 5, a thermal head 15, a platen roller 16, and a paper guide 17 as a printing mechanism unit 14 described in detail later are disposed.
[0015]
  As shown in FIG. 3, a reflection type sensor 40 is provided at the bottom of one corner on the other side of the sheet storage unit 6. The reflection type sensor 40 has a configuration in which four sensors 40a to 40d are arranged side by side. By irradiating light from each of the sensors 40a to 40d and measuring the reflectance, an identification mark 41 to be described later on the paper package 9 is obtained. Is supposed to read.
[0016]
  The paper separation unit 11 will be described.
  As shown in FIG. 5, a pickup roller 12 and a separation block 13 are provided at the end of the paper storage unit 6 on the side close to the printing mechanism unit 14. A pressing plate 18 is rotatably supported on the inner surface of the lid 10 facing the paper storage unit 6 side.
  An urging spring 19 is interposed between the pressing plate 18 and the lid 10, and an urging force in a direction to rotate the pressing plate 18 downward is always applied to the pressing plate 18.
[0017]
  The paper package 9 is a state in which the lower surface of the lowermost paper 7 is partially exposed from the package material 8 among the papers 7 that are stored in the stacked state with the printing surface facing downward. Thus, it is set in the paper storage unit 6. When the lid 10 is closed and locked, the pressing plate 18 urged downward by the urging spring 19 described above is passed through the package material 8 (a tongue 53 described later) and the paper 7 The area on the top side in the transport direction is pressed. As a result, the exposed portion of the sheet 7 comes into contact with the pickup roller 12 and is pressed with an appropriate force.
[0018]
  A separation block 13 is provided in the vicinity of the pickup roller 12, and the separation block 13 includes a separation guide surface 13 a that is inclined with respect to the sheet feeding direction of the pickup roller 12.
[0019]
  With this configuration, when the pickup roller 12 is rotationally driven, a conveying force is applied to the lowermost sheet 7 in contact with the pickup roller 12. Then, combined with the separation action of the separation guide surface 13a of the separation block 13, only one sheet 7 located at the lowermost layer is separated and sent out.
[0020]
  The printing mechanism unit 14 will be described.
  A platen roller 16 is rotatably provided adjacent to the separation block 13, and a paper guide 17 is disposed in the vicinity of the outer peripheral surface thereof.
  As shown in the enlarged view of FIG. 5, the paper guide 17 has a concave curved sliding contact surface 17 a along the outer peripheral surface of the platen roller 16. A pressing coil spring 20 is provided between the paper guide 17 and the main body case 2 so as to bias the sliding contact surface 17 a toward the outer peripheral surface of the platen roller 16.
[0021]
  In this configuration, the paper 7 separated by the paper separation unit 11 is conveyed by the pickup roller 12 and is between the lower end of the separation block 13 and the guide plate 21 for directing the paper toward the platen roller 16 side. Pass through.
  The sheet 7 is guided by the guide plate 21 and is fed between the platen roller 16 and the paper guide 17 from the lower surface side of the platen roller 16. Then, the sheet 7 is conveyed while being reversed between the platen roller 16 and the slidable contact surface 17a of the paper guide 17 while being reversed in a horizontal "U" shape by the rotational drive of the platen roller 16. Is directed to the upper surface side of the platen roller 16.
[0022]
  The thermal head 15 located on the upper surface side of the platen roller 16 has a heating element portion 15a. The thermal head 15 is provided so as to be rotatable around a rotation shaft 15 b, and the heating element 15 a can be brought into contact with and separated from the upper surface of the platen roller 16.
  The reason why the thermal head 15 is configured to be rotatable in this way is that the thermal head 15 interferes with the operation in the jam paper removing operation when the paper 7 is jammed between the platen roller 16 and the paper guide 17. This is to prevent it from becoming.
  One end of a torsion coil spring type spring 22 is engaged with the thermal head 15, and the heating element 15 a of the thermal head 15 constantly applies a biasing force in the direction approaching the upper surface of the platen roller 16.
  With this configuration, as described above, the heating element 15a of the thermal head 15 contacts the upper surface of the sheet fed by the platen roller 16 with the printing surface facing upward, and printing is performed on the sheet 7 at the contacted position. The
[0023]
  The thermal head 15 is a line head type, and can print arbitrary characters and images for each line extending in a direction orthogonal to the transport direction of the paper 7 on the heat-sensitive paper 7 being transported. The printing width when printing for one line is set to be approximately equal to the width of the paper 7 to be printed.
  As described above, the thermal head 15 is used as a print head by using thermal paper as a printing medium, so that consumables such as ink and an ink ribbon can be dispensed with and a mechanism for supplying ink can be omitted. This is because the printer 1 can be configured compactly.
  As the thermal paper, in this embodiment, a so-called thermal coloring type paper is used in which a color developing layer that is colored by heating of the thermal head 15 is formed on one side as an image receiving layer. However, the present invention is not limited to this, and for example, a perforated layer that is perforated by heating may be laminated on the base material layer to form an image receiving layer (thermally perforated type). Further, not only the thermal paper, but also a thermal transfer system or other paper can be used.
[0024]
  The separation block 13 is formed with a paper discharge guide surface 13 b inclined with respect to the paper feed direction of the platen roller 16.
  In this configuration, the sheet 7 on which printing has been performed by the heating element portion 15a of the thermal head 15 is guided by the sheet discharge guide surface 13b, and as shown by the chain line in FIG. And the lid 10 are discharged to the upper side of the lid 10.
[0025]
  [Configuration of paper package]
  Next, in the present embodiment, the paper package 9 set in the printer 1 will be described.
  6 is a perspective view of the paper package, and FIG. 7 is a development view of the package material. The process of manufacturing the paper package is shown in order in FIGS.
[0026]
  As shown in FIG. 6, the sheet package 9 has a plurality of sheets (for example, about 50 sheets) stacked therein and accommodated in the package material 8, for example, small-sized thermal sheets having a size of about A6 to A7. It is the composition which becomes. The user purchases the paper package sold in the state shown in FIG. 6, performs the process described later, exposes the internal paper, and then sets the paper package in the paper storage unit 6 of the printer 1 together with the package material 8. Has been.
[0027]
  The package material 8 is formed by bending a flat cardboard material (sheet-like member) into a box shape. A state before the cardboard material is bent is shown in FIG. The lid portions 59 are integrally formed.
[0028]
  Specifically, the relationship of each part of the package material 8 is as follows.
  That is, an end portion 52 is continuous with the end of the bottom portion 51 in the sheet conveyance direction, and a tongue portion 53 is formed continuously with the end portion 52.
  A side portion 54 is continuous with one side of the bottom portion 51 in the sheet conveyance direction, and a tongue fixing portion 55 is continuously formed on the side portion 54.
  A side portion 56 is continuous with the other side of the bottom portion 51 in the sheet conveyance direction, and the exterior portion 57 is continuously formed on the side portion 56.
  A top portion 58 is continuous with the top side of the bottom portion 51 in the sheet conveyance direction, and a lid portion 59 is continuously formed on the top portion 58.
[0029]
  The end portion 52, the side portions 54 and 56, and the top portion 58 serve to cover the edge side of the sheet 7 when the stacked sheets 7 are stored in the package material 8. These portions 52, 54, 56, and 58 are formed so as to extend from the four sides of the bottom 51 by the same length.
[0030]
  In this embodiment, the bottom 51 is fixed to the first part, the end 52 is connected to the second part, the tongue 53 is connected to the third part, and the side part 54 is connected to the fourth part. The part 55 corresponds to the fifth part.
[0031]
  An identification mark 41 as an identification unit is attached to the bottom 51 at one corner (surface on the lower side in the drawing of FIG. 7) at the end of the sheet conveyance direction by a known method such as printing. The identification mark 41 is configured to be positioned in the reading area of the reflective sensor 40 described above when the paper package 9 is set in the paper container 6 of the printer 1. A specific configuration of the identification mark 41 will be described later.
[0032]
  As shown by a thin chain line in FIG. 7, a crease process (streaking process) is performed on the boundary between the respective parts (51 to 59) such as the bottom formed in the package material 8. Thus, the cardboard material can be easily folded at the folds for convenience during assembly.
[0033]
  A printer set cut 31 is formed on the bottom 51, a lid fixing cut 32 and a tongue fixing cut (insertion port) 33 are formed on the tongue 53, and an exterior fixing cut 34 is formed on the tongue fixing portion 55. A part of the package material 8 can be inserted. Details will be described later.
[0034]
  [Paper package manufacturing process]
  First, the process for manufacturing the paper package 9 will be described below.
  As shown in FIG. 8, the cardboard material in the state of FIG. 7 has its end portion 52 bent perpendicular to the bottom portion 51 and the tongue portion 53 bent perpendicularly to the end portion 52. As a result, the tongue portion 53 is positioned above the bottom portion 51 in parallel with an appropriate interval (interval corresponding to the length of the end portion 52).
[0035]
  Next, as shown in FIG. 9, the side portion 54 is bent vertically with respect to the bottom portion 51, and the tongue fixing portion 55 is bent vertically so as to overlap the tongue portion 53, and is provided at the tip thereof. The protrusion 39 is inserted into a tongue fixing cut (insertion port) 33 formed in the tongue 53.
[0036]
  Furthermore, as shown in FIG. 10, the side portion 56 is bent vertically with respect to the bottom portion 51, and the exterior portion 57 is bent vertically so as to overlap the tongue portion 53 and the tongue fixing portion 55. The provided insertion portion 35 is inserted into the exterior fixing cut 34 provided in the tongue fixing portion 55.
[0037]
  As a result, a rectangular parallelepiped box as shown on the left side of FIG. 11 is formed. This box is open only on one side in the longitudinal direction (the leading side in the paper conveyance direction), and the other side is closed by the bottom 51 and the tongue 53, as well as the side parts 54 and 56 and the end part 52. Yes.
[0038]
  Then, as shown in FIG. 11, the stacked sheets 7 are inserted from the open side of the box body so as to be inserted between the bottom part 51 and the tongue part 53 of the cardboard material.
  When the paper 7 is inserted, the orientation is determined in advance so that the heat-sensitive surface (printing surface) of the paper 7 faces the bottom 51 side. This is to set the paper package 9 in the printer later so that the thermal surface of the paper 7 faces the thermal head 15 when the paper 7 is sent to the printing mechanism 14 of the printer.
[0039]
  After the sheet 7 is inserted, the top portion 58 is bent perpendicularly to the bottom portion 51 and the lid portion 59 is bent perpendicularly to the top portion 58 as shown in FIG. The lid portion 59 is folded over the tongue portion 53, and the insertion portion 38 at the tip of the lid portion 59 is inserted into the lid fixing cut 32 formed in the tongue portion 53.
  As a result, the lid portion 59 is closed and the open side of the box is fixed in a state covered with the top portion 58.
[0040]
  The paper package 9 shown in FIG. 6 is completed as described above. In the present embodiment, the manufacture of the paper package 9 is performed by the manufacturer, and the user who uses the printer 1 is sold in the state shown in FIG. The purchased paper package 9 is purchased, the following simple operation is performed on the paper package 9, and then set in the printer 1 for use.
[0041]
  [Setting the paper package to the printer]
  Next, an operation flow for setting the paper package 9 in the state of FIG. 6 to the printer will be described with reference to FIG.
  FIG. 17 is a perspective view showing a state where the paper package in a state immediately before being set in the printer is turned upside down. FIGS. 13 to 18 show the operation of setting the paper package in the printer step by step.
[0042]
  First, the user pulls out the insertion portion 38 of the lid portion 59 of the paper package 9 in the state shown in FIG. 6 from the lid fixing cut 32 and opens the lid portion 59 as shown in FIG.
  Then, as shown in FIG. 14, a finger is put on the cutout portion 45 formed in each of the exterior portion 57 and the tongue fixing portion 55 to cut off the cutout portion 45. As shown in FIG. 7, the two cutout portions 45 are formed in a portion extending from the exterior portion 57 or the tongue fixing portion 55 of the package material 8 to the bottom portion 51. In order to facilitate the work of cutting off the cutout portion 45, the package material 8 is perforated along the contour of the cutout portion 45 as shown in FIG.
[0043]
  By the cutting operation of the cutting portion 45, a part of the bottom portion 51 on the front side in the sheet conveying direction is folded downward (outside) together with the lid portion 59 and the top portion 58, with the crease line indicated by reference numeral A in FIG. Will be able to.
[0044]
  The user folds the lid portion 59, the top portion 58, and the bottom portion 51 outward with the crease line A as a boundary (FIG. 15), and then inserts the insertion portion 38 formed at the tip thereof into the bottom portion 51 of the package material 8. It is inserted into the printer set cut 31 formed as shown in FIG. 7 (FIG. 16).
  As described above, the lid 59 is fixed in an open state, and a part of the internal paper 7 is exposed from the package material 8.
[0045]
  FIG. 17 shows a state in which the paper package 9 with the lid 59 opened is turned upside down. A specific configuration of the identification mark 41 will be described with reference to FIG.
  The identification mark 41 is composed of four rectangular bit display portions 41 a to 41 d, and one to three of the four are colored black, while the remaining portions are not colored, and the underlying color of the package material 8. (White) is left. For example, in FIG. 17, the display portions 41a, 41c, and 41d are colored black, and the remaining display portions 31b are white without being colored. As the coloring method, a known method such as printing may be employed.
  The black-and-white pattern described above is the type of paper 7 stored in the package material 8 (for example, a normal type thermal paper, a thermal paper capable of two-color development, and a label portion formed on a release paper after printing. Label paper that can be peeled off as a label portion, copy paper that can be printed at the same time, etc.).
[0046]
  Next, as shown in FIG. 18, the paper package 9 is set in the paper storage unit 6 of the printer 1 with the bottom 51 side down. As a result, the portion of the lowermost sheet 7 that is stacked in the package material 8 that is exposed from the package material 8 comes into contact with the upper surface of the pickup roller 12. Accordingly, by rotating the pickup roller 12 in this state, the sheet 7 can be fed out and conveyed.
[0047]
  4 and 5 show the state in which the lid body 10 is closed after that. At this time, the tongue 53 is placed between the pressing plate 18 for pressing the paper 7 against the pickup roller 12 and the paper 7. To position.
[0048]
  In this way, the sheet 7 is set in the printer 1 in the form of the sheet package 9, and when the sheets 7 are fed out one by one, the remaining package material 8 is taken out from the printer 1 and discarded. Become.
  This configuration is useful in that even when a large number of sheets are printed by the printer 1, the sheet separation performance of the pickup roller 12 and the separation block 13 does not deteriorate. That is, if the sheet 7 is in direct contact with the pressing plate 18 without the tongue 53, the pressing plate 18 is worn by continuous use of the printer 1 and the frictional force between the sheet 7 and the sheet 7 is reduced. A phenomenon (multiple feeding) in which the action is lowered and a plurality of sheets 7 are simultaneously fed easily occurs. In this regard, in the configuration of the present embodiment, the sheet 7 is in direct contact with the tongue 53, and the tongue 53 is replaced with a new one together with the package material 8 every time a predetermined number of sheets 7 are used up. For many years, the frictional force between the tongue 53 and the paper 7 does not decrease, and a good separation action is always performed, thereby preventing paper conveyance troubles such as double feeding.
[0049]
  The tongue 53 of the paper package 9 is positioned in the paper storage unit 6 by bringing at least a part of its edge into contact with a positioning member (not shown) provided in the paper storage unit 6.
  By this positioning, the four bit display portions 41a to 41d of the identification mark 41 are positioned in the reading areas of the four reflective sensors 40a to 40d. The printer 1 can automatically determine the type of paper by reading the black and white patterns of the bit display portions 41a to 41d with the reflective sensor 40.
[0050]
  As described above, the package material of the paper package 9 includes the bottom portion (first portion) 51, the end portion (second portion) 52, the tongue portion (third portion) 53, and the side portion (first portion). (Four parts) 54 and a tongue fixing part (fifth part) 55.
  The bottom 51 is provided with an identification mark (identification unit) 41 that can be read by the reflective sensor 40 of the printer 1. Further, the tongue 53 is positioned in the sheet storage portion 6 of the sheet package 9 by at least a part of the edge of the tongue 53 coming into contact with the positioning member on the printer 1 side.
  In this configuration, as shown in FIG. 9, the tongue fixing portion 55 that is continuous to the bottom portion 51 via the side portion 54 is fixed to the tongue portion 53 that is also continuous to the bottom portion 51 via the end portion 52. Accordingly, the tongue 53 is prevented from moving relative to the bottom 51 in the direction along the sheet conveyance direction.
[0051]
  As a result, when the paper package 9 is set in the paper storage unit 6, the tongue 53 is positioned with respect to the printer 1, and the bottom 51 is fixed to the tongue 53 by fixing the tongue fixing unit 55 and the tongue 53. Firmly positioned against. Accordingly, since the bottom 51 can be positioned at an accurate position with respect to the printer 1, the identification mark 41 can be accurately positioned in the reading area of the reflective sensor 40. The error of discriminating the paper as the original paper is prevented.
[0052]
  If the tongue fixing portion 55 and the tongue portion 53 are not fixed, as shown in the examples of FIG. 19 and FIG. 20, the bottom portion 51 is in the longitudinal direction of the tongue 53 (the above-described paper transport direction). May be displaced relatively. 19 and 20, it can be seen that the end portion 52 is not perpendicular to the tongue portion 53 and the bottom portion 51 and is inclined by the amount of the deviation.
  Due to this displacement, the position of the identification mark 41 is also displaced, and as a result, the accuracy of the pattern determination of the identification mark 41 by the reflective sensor 40 of the printer 1 is lowered.
  In this respect, in the present embodiment, the paper package 9 can be set in the printer 1 in the state as shown in FIG. 18 without the above-described deviation by fixing between the tongue fixing portion 55 and the tongue portion 53. Therefore, the reading accuracy of the reflective sensor 40 is improved. Further, since the fixing is a simple configuration in which the protrusion 39 is simply inserted into the tongue fixing cut 33, the manufacturing cost and man-hour of the paper package 9 can be reduced.
[0053]
  Although the embodiments of the present invention have been described above, the technical scope of the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.
  For example, the identification mark 41 displays the type of the paper 7 in this embodiment, but is not limited thereto. In short, any information may be displayed so that it can be read by the sensor on the printer side. The configuration of the identification mark 41 is not limited to the black and white pattern of the rectangular bit display portion attached by printing. For example, holes can be formed at appropriate locations on the paper package 9 and some information can be displayed by the pattern of the presence or absence of the holes. A configuration is possible.
  The sensor on the printer side is not limited to the reflection type sensor 40 as described above, and an appropriate sensor may be adopted regardless of the contact / non-contact type.
