Description

  The present invention relates to a paper package and a package material mounted on a printer.

  2. Description of the Related Art Conventionally, there has been known a recording paper package in which an entire package for storing and storing recording paper is attached to the printer side when the recording paper is attached to a printer (see, for example, Patent Document 1).

  According to Patent Document 1, the recording paper is stored in a box-shaped package made of a member such as cardboard, and a perforation is formed so as to remove a portion to which a paper feed roller or the like of the package hits. When mounting, the user removes unnecessary portions along the perforation and directly sets the package on the printer side.

JP-A-60-97145

  However, the package shown in Patent Document 1 is formed to be slightly larger than the recording paper so that the recording paper can be easily stored therein. There is a risk that trouble (so-called skew feeding) may occur in which the recording paper is not positioned at the paper position but is conveyed obliquely toward the printing mechanism of the printer. If the gap between the package and the recording paper is made small in order to prevent this skew, there is a problem that it becomes difficult to store the recording paper in the package.

  As a method for preventing skew feeding, there is a method of positioning a recording paper feed position in a recording paper loading chamber of a printer. For example, as a positioning method in a printer apparatus that feeds recording sheets loaded in a recording sheet loading chamber of a printer one by one with a sheet feeding roller, it is provided at a side portion in the recording sheet conveyance direction in the recording sheet loading chamber. There is a method of regulating the position of the recording paper by pressing the side surface of the laminated recording paper in one direction by the spring member and pressing the entire side surface of the recording paper against the wall facing the spring member of the recording paper loading chamber. .

  However, in order to directly press the recording paper in the package shown in Patent Document 1 with the spring member, the spring member is placed at a predetermined position of the printer facing the portion where the unnecessary portion of the package is removed, that is, the portion where the paper feed roller or the like hits. When arranged, the spring member can only press the upstream portion in the recording paper conveyance direction. Accordingly, the downstream portion in the recording paper conveyance direction is not pressed and is not positioned at an appropriate position, so that the recording paper is inclined in the package, and there is a possibility that the recording paper is skewed during conveyance of the recording paper.

  Even if the spring member is disposed so as to press the downstream side in the recording paper conveyance direction, the spring member presses the outside of the package including the recording paper because the recording paper side surface is covered with the package. It is not possible to position the recording paper directly.

FIG. 4 is a side sectional view showing a state in which recording paper is set in the recording paper loading chamber. FIG. 5 is an enlarged cross-sectional view showing details of the recording paper separating section and the printing mechanism section.

  As shown in FIG. 1, the printer 1 has a compact configuration with a rectangular shape (size that can accommodate recording paper of A6 to A7 size) in a plan view and a thickness of about 2 cm or less. Has been.

  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.

  A recording paper loading chamber 6 is formed in the remaining portion of the upper surface side of the frame 3 except for the portion covered with the upper cover 5 as shown in FIG. In this recording paper loading chamber 6, a recording paper package 9 in which a plurality of A6 to A7 size cut sheet-like thermal paper (printed medium; hereinafter referred to as “recording paper”) 7 is housed in a package material 8 is provided. As shown in FIG.

  The upper portion of the recording paper loading chamber 6 is covered with a lid (lid portion) 10, and this lid 10 is located on the upstream side in the conveyance direction of the recording paper 7 (left end in FIG. 2) as indicated by the arrow in FIG. The shaft is rotatable. FIG. 3 shows a state where the lid 10 is opened. The main body case 2 and the lid body 10 are provided with a lock mechanism (not shown), and the lid body 10 is closed as shown in FIG. 4 with the recording paper package 9 set in the recording paper loading chamber 6 as described above. Can be locked.

  Further, the display unit 42 of the package material 8 is provided on the cover 10 so that the user can check the display unit 42 printed on the package material 9 stored in the recording paper loading chamber 6 with the cover 10 closed. A display window 10a is provided at a position opposite to.

  At one end of the recording paper loading chamber 6, a pickup roller (paper feeding roller) 12 as a recording paper separation unit 11, a separation block 13, and the like are disposed. 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 to be described in detail later are arranged (see FIG. 2).

  As shown in FIG. 3, the recording paper loading chamber 6 is formed as a rectangular recess capable of accommodating the recording paper package 9.

  The inner wall on one side of the recess (one end in the width direction of the recording paper 7) is provided with recesses 30 and 31 at two locations, and guide members (pressing members) are provided inside the recesses 30 and 31. ) 32 and 33 are arranged.

  The base portions 32a and 33a are provided with springs (not shown) to apply a biasing force in the direction in which the arms 32b and 33b protrude toward the recording paper loading chamber 6 (the direction indicated by the arrow in FIG. 3). Therefore, when the recording paper package 9 is accommodated in the recording paper loading chamber 6, the arms 32b and 33b abut against the side edges of the recording paper 7 in the recording paper package 9, and the recording paper 7 is moved to the recording paper. The recording chamber 7 is pressed against the inner wall (positioning portion) 35 on the other side of the loading chamber 6 to prevent skewing.

  With this configuration, the guide members 32 and 33 are provided small, so that the printer 1 is configured compactly.

  In addition, a reflection type sensor 40 in which four sensors 40 a to 40 d are arranged side by side is provided at the bottom of the recording paper loading chamber 6. The reflection type sensor 40 reads the identification mark 41 by irradiating light to an identification mark (identification unit) 41 (described later) of the recording paper package 9 from each sensor 40a to 40d and measuring the reflectance. It has become.

  Next, the recording paper separating 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 recording paper loading chamber 6 on the printing mechanism section 14 side. A pressing plate 18 is supported on the inner surface of the lid 10 facing the recording paper loading chamber 6 so as to be rotatable on the upstream side in the transport direction with the center as an axis.

  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.

  The recording paper package 9 partially exposes the lower surface of the lowermost recording paper 7 from the packaging material 8 among the recording papers 7 stored in a stacked state with the printing surface facing downward. In this state, it is set in the recording paper loading chamber 6. When the lid 10 is closed and locked, the pressing plate 18 urged downward by the urging spring 19 described above is a region upstream of the recording paper 7 in the recording paper conveyance direction via the package material 8. Press. As a result, the exposed portion 7c of the recording paper 7 comes into contact with the pickup roller 12 and is pressed with an appropriate force.

  A separation block 13 is provided in the vicinity of the pickup roller 12, and this separation block 13 includes a separation guide surface 13 a inclined with respect to the recording paper feed direction of the pickup roller 12.

  With this configuration, when the pickup roller 12 is rotationally driven, a conveying force is applied to the lowermost recording paper 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 of recording paper 7 located at the lowermost layer is separated and sent out.

  Next, 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 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 urge the sliding contact surface 17 a toward the outer peripheral surface of the platen roller 16.

  In this configuration, the recording paper 7 separated by the recording paper separating unit 11 is conveyed by the pickup roller 12 and a paper guide for directing the lower end of the separation block 13 and the direction of the recording paper to the platen roller 16 side. 17 passes between the guide plates 21 integrally provided with the guide plate 21.

  The recording paper 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 recording paper 7 is conveyed along the circumference of the platen roller 16 by the rotational drive of the platen roller 16 while being held between the outer peripheral surface of the platen roller 16 and the sliding contact surface 17a of the paper guide 17 for printing. It reaches the upper surface side of the platen roller 16 with its surface facing upward.

  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 work in the jam paper removing operation when the recording 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 recording paper fed by the platen roller 16 with the printing surface facing upward, and printing is performed on the recording paper 7 at the contact point. Is made.

  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 conveyance direction of the recording paper 7 on the thermal recording sheet 7 being conveyed. it can. The printing width for printing one line is set to be approximately equal to the width of the recording 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 recording paper can be used.

  The separation block 13 is formed with a paper discharge guide surface 13 b that is inclined with respect to the recording paper feed direction of the platen roller 16.

In this configuration, the recording paper 7 on which printing has been performed by the heating element portion 15a of the thermal head 15 is guided by the paper discharge guide surface 13b, and a gap formed between the upper cover 5 of the main body case 2 and the lid 10. Then, the paper is discharged to the upper side of the lid 10 (see FIG. 1).
[Configuration of recording paper package]
Next, the recording paper package 9 set in the printer 1 in this embodiment will be described.

  FIG. 6 is a perspective view of the recording paper package 9, and FIG.

  As shown in FIG. 6, the recording paper package 9 has a plurality of sheets (for example, 50 sheets) of thermal paper 7 in the form of small sheets, for example, A6 to A7 size, with the printing surface facing downward inside the package material 8. About) The sheets are stacked and accommodated, and further, the belt-shaped member 60 is configured such that the central portion in the longitudinal direction of the recording paper package 9 is wound in the width direction and bundled. The user removes the belt-like member 60 from the state of FIG. 6 and stores it in the recording paper loading chamber 6 of the printer 1.

  The package material 8 is assembled by bending a flat cardboard material (sheet-like member). A state before the cardboard material is bent is shown in FIG. 7, and the shape of the cardboard material is such that the upper portion 53, the end portion 52, and the bottom portion 51 are integrally formed.

  Specifically, the relationship of each part of the package material 8 is as follows.

  That is, the end portion 52 is formed continuously on the upstream side (the lower side in FIG. 7) of the bottom 51 in the recording paper conveyance direction.

  On the other side of the end portion 52 where the bottom 51 is continuously formed, an upper portion 53 is continuously formed.

  The length in the width direction (length A in FIG. 7) of the three consecutive portions 51 to 53 is configured to be the same length as the width direction of the recording paper 7 to be stored.

  Further, the length of the upper portion 53 in the longitudinal direction (length C in FIG. 7) is configured to be the same length as the longitudinal direction of the recording paper 7, and the length in the longitudinal direction of the bottom portion 51 (length in FIG. 7). B) is shorter than the length C of the upper portion 53 to such an extent that the pickup roller 12 provided in the printer 1 can come into contact with the recording paper 7. That is, as shown in FIG. 6, the upper portion 53 is configured to have the same size as the recording paper surface, and covers the entire top surface of the stacked recording paper 7. The upstream edge of the recording paper 7 in the transport direction is covered by an end portion 52 that is provided continuously with the upper portion 53, and the bottom portion 51 that is continuous with the end portion 52 is further laminated. Covers the bottom surface. At this time, the lowermost surface of the stacked recording sheets 7 on the downstream side in the transport direction is not covered with the package material 8 and the recording sheets 7 are exposed. When the recording paper package 9 is stored in the recording paper loading chamber 6 of the printer 1, a portion (first exposed portion) 7c where the recording paper 7 is exposed comes into contact with a pickup roller 12 provided on the printer side. (See FIG. 5).

  Further, as shown in FIG. 6, the side edges 7a, 7b in the longitudinal direction of the recording paper 7 surrounded by the bottom 51, the end 52, and the top 53 are not covered with the package material 8, It is in an exposed state. One end edge (second exposed portion) 7 a where the recording paper 7 is exposed is a guide member 32 provided on the printer side when the recording paper package 9 is stored in the recording paper loading chamber 6 of the printer 1. , 33 are in contact with the arms 32b and 33b. The other edge 7 b where the recording paper 7 is exposed contacts the inner wall 35 of the recording paper loading chamber 6 facing the guide members 32 and 33.

  The upper portion 53 is provided with a display unit 42 so that the user can check from the display window 10b of the printer when the recording paper package is set in the recording paper loading chamber 6 of the printer 1. The display unit 42 includes a type of recording paper stored in the package material 8 (for example, a normal type thermal paper, a thermal paper capable of two-color development, a label portion formed on a release paper, and a label portion after printing. Label paper that can be peeled off and used as an adhesive label, copy paper that can be printed at the same time, etc.) are attached by a known method such as printing.

  An identification mark 41 as an identification unit is attached to the bottom 51 at a corner on the upstream side in the transport direction by a known method such as printing (see FIG. 7). The identification mark 41 is configured to be positioned in the reading region of the reflection type sensor 40 when the recording paper package 9 is set in the recording paper loading chamber 6 of the printer 1.

  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. 7, the display units 41a, 41b, and 41c are colored black, and the remaining display unit 41d is white without being colored. As the coloring method, a known method such as printing may be employed.

  The above black-and-white pattern is printed by forming the type of recording paper 7 housed in the package material 8 (for example, a normal type thermal paper, a thermal paper capable of two-color development, and a label portion on a release paper. Label paper that can be peeled off later to form a sticky label, copy paper that can be printed at the same time, etc.).

  The printer 1 can automatically determine the type of the recording paper by reading the black and white patterns of the bit display portions 41a to 41d with the reflective sensor 40.

  As shown by a broken line in FIG. 7, a crease process (streaking process) is applied to the boundary between the respective parts (51 to 53) 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.

  When the recording paper 7 is stored, the package material 8 shown in FIG. 7 is folded so that the surface on which the display unit 42 and the identification mark 41 are printed is on the outer side, and the bundle of stacked recording papers 7 is packaged. It is only necessary to be sandwiched between the constituent parts 51 to 53 of the material 8.

  In the present embodiment, the bottom 51 corresponds to the first part, the end 52 corresponds to the second part, and the upper part 53 corresponds to the third part.

  Here, since the band-like member 60 in which the recording paper package 9 is wound and bundled can bundle the package material 8 and the recording paper 7 together, the user stores the recording paper package 9 in the printer 1 or the like. Convenience is also improved during operation.

Further, in the configuration of the present embodiment, the length in the width direction of the package material 8 (length A in FIG. 7) is the same as the length in the width direction of the recording paper 7, but may be configured to be shorter than that. Good. However, since the length is the same as the width of the recording paper, the printing surface can be protected more reliably. Further, when it is desired to align the ends of the recording paper 7 stacked in the recording paper package 9, the package material 8 is used. Since the recording paper 7 can be easily aligned by aligning the edge of the recording paper 7 and the edge of the recording paper 7, the length in the width direction of the package material 8 is preferably the same as that of the recording paper 7.
[Setting the recording paper package to the printer]

  As shown in FIG. 9, the guide members 32 and 33 provided in the recording paper loading chamber 6 as described above rotate in the direction of the arrow in the figure, whereby the arm 32b provided in the guide members 32 and 33 is provided. , 33b is pressed against the side edge 7a of the recording paper 7.

  When the edge 7a is pressed, the entire recording paper 7 moves in a direction perpendicular to the transport direction (right direction in FIG. 10), and the other edge 7b contacts the inner wall 35 on the side of the recording paper loading chamber 6. Touch.

  As shown in FIG. 10, the arms 32b and 33b press the edge 7a of the recording paper 7 from two locations on the upstream side and the downstream side in the transport direction. By pressing the edge 7a of the recording paper 7 at two locations, the recording paper 7 can be moved as a whole.

  As described above, the recording paper package 9 is stored in the recording paper loading chamber 6, and the lid 10 of the printer 1 is closed and locked, so that the pressing plate 18 provided inside the lid 10 is moved to the recording paper package 9. Is pressed from above, and the portion 7 c of the lowermost recording paper 7 that is laminated in the package material 8 is exposed from the package material 8 and contacts the upper surface of the pickup roller 12. Therefore, by rotating the pickup roller 12 in this state, the recording paper 7 can be fed out and conveyed.

  Further, since the pressing plate 18 presses the recording paper package 9 from above, the position of the recording paper package 9 positioned by the guide members 32 and 33 described above is fixed without shifting. As described above, the recording paper package 9 is positioned to prevent the recording paper 7 from skewing during conveyance.

  When all of the recording paper 7 of the recording paper package 9 accommodated in the recording paper loading chamber 6 of the printer 1 has been transported, the user takes out the remaining package material 8 from the recording paper loading chamber 6 and creates a new recording paper 7. This bundle is sandwiched between the components 51 to 53 of the package material 8 so that the printing surface of the recording paper 7 is in contact with the bottom 51, and is set in the printer 1 as described above, so that printing can be performed again.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, the package material 8 in the present embodiment is composed of three consecutive parts including a bottom part 51, an end part 52, and an upper part 53. However, the present invention is not limited to this, and as shown in FIG. The recording paper loading chamber 6 may further include a side portion 54 that covers the entire edge 7 b of the recording paper 7 on the side facing the inner wall 35.

  Also, the shape excluding the end portion 52 of the package material 8 shown in FIG. It may be.

  Further, when the recording paper package 9 is set in the recording paper loading chamber 6, in order to securely fix the position of the recording paper package 9, an alignment notch portion is provided in the identification mark 41 printed on the package material 8. Also good. Specifically, in the white portion 41d of the identification mark 41 printed on the bottom portion 51 of the package material 8 as shown in FIG. 7, an H-shaped cut (alignment cut portion) is provided in advance as shown in FIG. Put 45. Then, when setting the printer 1, the user bends the claw 45 a outward from the notch 45 as shown in FIG. 12B and fits the corresponding sensor 40 d of the reflective sensor 40 of the printer 1. By doing so, alignment within the printer 1 is performed (see FIG. 13).

  With this configuration, the position can be reliably aligned by the identification unit, and the type of the recording paper package 9 can be accurately identified, and the recording paper 7 can be correctly identified and printed. At this time, a hole 46 is formed in a portion where the nail 45a of the package material 8 is bent outward. However, since the recording paper 7 is white, the reflective sensor 40 can correctly determine the type of the recording paper 7.

  One sheet of colored paper may be added between the uppermost recording paper 7 stacked in the recording paper package 9 and the upper portion 53 of the package material 8. When printing, a sheet other than the recording sheet 7 is conveyed, so that the user can confirm that there is no recording sheet 7 in the printer.

  Accordingly, it is possible to prevent the waste of performing the paper feeding operation even when the recording paper 7 is not present in the printer 1 and to prevent the package material 8 from being deteriorated due to the pickup roller 12 being in direct contact with the package material 8 and rotating. Can do. Thus, by preventing the package material 8 from being deteriorated, the package material 8 can be used a plurality of times.
