Definitions
- the present invention relates to a sheet package, and more particularly to a sheet package that protects the outside of a stack of sheets with its package member and that can be set in a printer unit together with a package material.
- the conventional sheet package has no pressing means for supporting sheets contained in the interior, when the opening portion of a sheet package is directed in a downward direction during the handling of a sheet package, sheets can drop out.
- the present invention has been accomplished to solve the above-described problems and a first object of the invention is to prevent sheets taken out from the sheet package temporarily from being inserted back into their original storage position within the sheet package. Further, a second object of the invention is to achieve a sheet package out of which sheets do not drop.
- the printer unit 1 is formed into a flat type rectangular parallelpiped configuration approximately 2 cm in thickness, while its rectangular shape as seen in a plan view is slightly larger than A6 size.
- a main body case 2 which constitutes a casing of the printer unit 1 is comprised of a frame body 3, a lower cover 4, an upper cover 5, a lid body 10 and the like.
- the frame body 3 constitutes a frame of the printer unit 1, presenting a rectangular shape as seen in its plan view.
- the lower cover 4 covers the bottom face of the frame body 3, presenting a rectangular shape as seen in its plan view.
- the upper cover 5 covers part of the top face of the frame body 3.
- the lid body 10 is structured so as to be capable of being opened and closed.
- a printing mechanism portion 14 is incorporated inside an end portion (upper side in FIGS. 2 and 3 ) of the printer unit 1 and the rectangular upper cover 5 as seen in its plan view is provided in such a way as to cover its top face.
- a sheet storage portion 6 is formed in the remaining portion of the top face of the frame body 3 that excludes the portion covered by the upper cover 5.
- the top of the sheet storage portion 6 is covered by the rectangular lid body 10 as seen in its plan view.
- the lid body 10 can be opened and closed freely as shown in FIG. 2 .
- the sheet storage portion 6 can accommodate a sheet package 9 in which a plurality of sheets 7, for example A6 or A7 sized cut-sheet type heat sensitive papers, can be stored inside a package material 8, as shown in FIG. 3 .
- the main body case 2 is equipped with a locking mechanism (not shown), and when a sheet package 9 set in the sheet storage portion 6, the lid body 10 can be closed and locked as shown in FIG. 3 .
- a pickup roller 12, a separation block 13 and the like are disposed as a sheet-separating portion 11 at an end portion on the printing mechanism portion 14 side of the sheet storage portion 6.
- a thermal head 15, a platen roller 16 and a paper guide 17 are disposed as a printing mechanism portion 14 below the upper cover 5.
- the paper separation portion 11 will next be described with reference to FIG. 4 .
- the pickup roller 12 and the separation block 13 are provided at an end portion on a side close to the printing mechanism portion 14 of the sheet storage portion 6.
- a pressing plate 18 is supported in condition where it can swing.
- a coil-like urging spring 19 is interposed between the pressing plate 18 and the lid body 10 so as to apply constantly to the pressing plate 18 an urging force in a direction of the rotation of the pressing plate 18 in a downward direction.
- the sheet package 9 is loaded into the sheet storage portion 6 with the printing object faces of the sheets 7 being directed in a downward direction, and in a state in which a bottom face of a sheet 7 located at the bottommost position of sheets 7 stored in the sheet package 9 in a stacked condition is exposed partly from the package material 8. Then, when the lid body 10 is closed and locked, the pressing plate 18 urged by the urging spring 19 in a downward direction presses the exposed portion of the sheet 7 against the pickup roller 12 through the package material 8 so that the bottom face of the sheet 7 is brought into contact with the pickup roller 12.
- the separation block 13 which constitutes the sheet-separating portion 11 is provided such that it is located in the vicinity of and opposes the pickup roller 12.
- the separation block 13 has a separation guide face 13a which is inclined with respect to a direction of feeding sheets by the pickup roller 12.
- the pickup roller 12 is driven so that a frictional transportation force is applied to the sheet 7 that is located on the bottommost layer and that is in contact with the pickup roller 12. Then, only the sheet 7 located on the bottommost layer is separated and fed by the separating action of the separation guide face 13a of the separation block 13 in tandem with the frictional transportation force.
- the platen roller 16 is provided being driven rotatably by a motor (not shown) on the opposite side to the pickup roller 12 across the separation block 13, and the paper guide 17 is disposed in the vicinity of the outer peripheral face of the platen roller 16.
- the paper guide 17 has a concavely curved sliding contact face 17a that possesses a substantially U-shaped section as seen in a lateral direction, and the paper guide 17 is provided so as to extend along the outer peripheral face of the cylindrical 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 face 17a toward the outer peripheral face of the platen roller 16.
- a sheet 7 separated by the sheet-separating portion 11 is conveyed by the pickup roller 12 and passes between the bottom end of the separation block 13 and a guide plate 21 that guides the sheet in the direction of the platen roller 16.
- the sheet 7 is guided by the guide plate 21 and guided from the bottom side of the platen roller 16 to a portion between the platen roller 16 and the paper guide 17.
- the sheet 7 is held between the outer peripheral face of the platen roller 16 and the sliding contact face 17a of the paper guide 17 and conveyed in a state in which it is inverted into a U shape as seen in a lateral direction by a rotation of the platen roller 16.
- the sheet accordingly reaches the top side of the platen roller 16 with its printing object face facing an upward direction.
- the thermal head 15 that is located above the platen roller 16 has a heat-generating body portion 15a.
- the thermal head 15 is provided rotatably around a rotation shaft 15b, and the heat generating body portion 15a is configured in such a way as to be capable of making contact with, and moving away from, the top face of the platen roller 16.
- the reason why the thermal head 15 is configured in such a way as to be rotatable is that in removing a jammed paper when a sheet 7 is jammed between the platen roller 16 and the paper guide 17, the thermal head 15 is in this way prevented from becoming an impediment to that removal work.
- an end of a torsion coil type spring 22 is attached to the thermal head 15 so as to always apply an urging force constantly in a direction in which the heat-generating body portion 15a of the thermal head 15 is made to approach the top face of the platen roller 16.
- the heat-generating body portion 15a of the thermal head 15 makes contact with the top face of a sheet 7 conveyed by the platen roller 16 with its printing object face directed in an upward direction and, the sheet 7 is then printed at the position where contact is made.
- the thermal head 15 is of a line head type and can accordingly print any character or image on each individual line extending in a direction perpendicular to the conveyance direction of the sheet 7 on the conveyed heat sensitive type sheet 7.
- a printing width at the time that printing is performed on a single line is set so as to substantially equal to the width of the paper 7 which is a printing object. Because the thermal head 15 is used as a printing head, a heat sensitive paper is used as a printing object medium and thus, consumables such as ink and ink ribbon are reduced. Further, a mechanism for supplying ink can be abolished, thereby resulting in a compact structure of the printer unit 1.
- heat sensitive coloring type having a coloring layer which generates color when heated by the thermal head 15, and a heat sensitive boring type in which a boring layer is overlaid on a base material layer and in which, the boring layer being bored when heated and other types are available.
- a sheet discharge guide face 13b which is inclined with respect to a sheet-feeding direction of the platen roller 16, is formed on the separation block 13.
- the sheet package 9 is made up of the package material 8 which is folded into a rectangular parallelepiped thin box.
- the sheet package 9 contains a plurality of sheets (recording object mediums) 7 composed of, for example, A6-A7 size cut-sheet like heat sensitive papers in a stacked condition.
- Users purchase sheet packages 9 that are put on sale in a box type condition shown in FIG. 5 .
- a lid portion 44 is opened and folded back to the rear side.
- An insert section 44d of the lid portion 44 is inserted into a third slit 45 in a bottom portion 40, which will be described later so as to expose sheets 7 located on the inside. Then, the user sets the sheets together with the package material 8 in the sheet storage portion 6 of the printer unit 1 and uses.
- the package material 8 is formed by punching out a flat thick paper.
- the rectangular bottom portion 40 as the first portion, for covering one face in a stack direction of the stacked sheets 7 is provided in the central portion of the package material 8.
- the lid side in a discharge direction of the sheet 7 in the sheet package 9, that is, right side in FIG. 8 of the package material 8 is defined to be front side and the left side on opposite side is defined to be rear side.
- a rectangular side wall portion 42 as the fourth portion is extended from the other side end portion.
- a rectangular side wall portion 43 as the fifth portion is extended from the rear end portion of the bottom portion 40.
- the side wall portion 43 receives the bottom end portion of the sheets 7 when the sheet package 9 is assembled.
- the heights of the side wall portions 41-43 are all the same and larger than the stack height of the sheets 7 stored in the sheet package 9.
- the lid portion 44 is extended from the front end side of the bottom portion 40.
- the lid portion 44 is comprised of a lid base portion 44a, a lid side wall portion 44b, a lid front end portion 44c and the insert section 44d.
- the lid base portion 44a is formed in a rectangular shape.
- the lid side wall portion 44b is formed in a rectangular shape and is extended from the lid base portion 44a, having the same height (width in a short side direction) as the heights of the side wall portions 41 to 43.
- the lid front end portion 44c is extended from the lid side wall portion 44b and a width thereof is smaller than that of the lid side wall portion 44b.
- the insertion portion 44d is extended from the lid front end portion 44c and a width thereof is smaller than the lid front end portion 44c.
- a pair of inclined sides is provided at the front end of the insertion portion 44d.
- a shape that is formed by a combination of the bottom portion 40 and the lid base portion 44a is substantially the same shape as a sheet 7.
- a rectangular first sheath portion 50 as the second portion, for covering the sheets 7 in such a way that it opposes the bottom portion 40 after assembly is extended from the side wall portion 41 of the bottom portion 40.
- the first sheath portion 50 has a first slit 51 in which the insert section 44d of the lid portion 44 is inserted and a second slit 52 in which an insert section 61 of a second sheath portion 60 is inserted.
- a square cutout portion 53 for detecting the presence/absence of a sheet 7 is provided in a side end portion on the lid base portion 44a side of the first sheath portion 50.
- the printer unit 1 detects the presence/absence of a sheet 7 with the use of the cutout portion 53.
- the sheet package 9 is loaded in the sheet storage portion 6 of the printer unit 1 in the state shown in FIG. 6 , and the printer unit 1 is provided with a reflection type optical sensor 80 (see FIGS. 3 and 4 ) at a position opposite to the cutout portion 53.
- the reflection type optical sensor 80 detects reflection of light from the sheets 7 and if no sheet 7 is present, the reflection type optical sensor detects reflection light from a synthetic resin which constitutes the rear face of the lid body 10. Therefore, if as the color of the synthetic resin which constitutes the sheet storage portion 6, a color having a low reflectance ratio is set, the presence/absence of a sheet can be easily detected.
- three sensor marks 46 which indicate the type and size of sheets 7 stored in the sheet package 9 are printed on an end portion on the first sheath portion 50 side of the bottom portion 40 on the front side (outer side) of the package material 8.
- These sensor marks 46 are read by a reflection type optical sensor (a sensor (not shown) that is different from the reflection type optical sensor 80), and that is provided on the printer unit 1. For example, if a sensor mark 46 is printed, it is regarded as "1", and the sensor mark 46 is not printed, it is regarded as "0", then the absence of a sheet and seven different types of sheets 7 can be identified with the combination of presence or absence of the three sensor marks 46.
- the bottom portion 40 is provided with a third slit 45 in which the insert section 44d of a folded back lid portion 44 is to be inserted.
- a cut-in portion 54 which is cut to a predetermined length from the cutout portion 53 side is provided between the side wall portion 41 and the first sheath portion 50. The cut-in portion 54 facilitates deflection of the first sheath portion 50 when the first sheath portion 50 is pressed if the sheet package 9 is loaded on the sheet storage portion 6.
- a second sheath portion 60 for fixing the first sheath portion 50 for covering the sheets 7 in such a way that it opposes the bottom portion 40 after assembly is provided so as to extend as far as side wall portion 42 of the bottom portion 40.
- the width of the second sheath portion 60 is smaller than that of the first sheath portion 50 and an insert section 61 is formed on a side end portion of the second sheath portion 60.
- Rectangular ear portions 71 and 72 are provided on both end portions in the longitudinal direction of the tongue portion 70. When the ear portions 71 and 72 are fold, they perform as sheet intrusion blocking members.
- a portion indicated with two-dot and chain line in both FIGS. 8 and 9 is a portion that is subjected to fold line processing and the fold line facilitates folding of a thick paper for convenience of assembly.
- the ear portions 71 and 72 on both end portions in the longitudinal direction of the tongue portion 70 are folded back and the stacked sheets 7 are loaded on the bottom portion 40.
- the tongue portion 70 of the package material 8 is fold over.
- the first sheath portion 50 is folded in such a way that it overlaps with the top of the tongue portion 70 and as shown in FIG. 13 , the second sheath portion 60 is folded over the first sheath portion 50.
- the insert section 61 of the second sheath portion 60 is inserted into the second slit 52 in the first sheath portion 50.
- the lid portion 44 is folded over the first sheath portion 50, the insert section 44d of the lid portion 44 is inserted into the first slit 51 in the first sheath portion 50, and the sheet package is thus completed.
- Sheet packages 9 are sold in this condition. Because this condition allows the ear portions 71 and 72 to seek to be elastically restored within the sheet package 9, they press against the surface of the stacked sheets 7.
- the lid portion 44 of the sheet package 9 in the state shown in FIG. 5 is erected as shown in FIG. 15 and folded back to the rear side along the line II-II in FIG. 16 .
- the insert section 44d of the lid front end portion 44c of the lid portion 44 is inserted into the third slit 45 of the bottom portion 40 and the lid portion 44 is fixed to the bottom portion 40. Consequently, as shown in FIG. 6 , the sheet package 9 reverts to a state in which the front end portion of the sheets 7 is exposed.
- the sheet package 9 in this state is stored in the sheet storage portion 6 of the printer unit 1 as shown in FIG. 3 .
- the lid body 10 is closed, the first sheath portion 50 of the sheet package 9 is pressed by the pressing plate 18 and the sheet that is located on the bottommost layer of the stacked sheets 7 is pressed against the pickup roller 12.
- the reflection type optical sensor 80 that is provided on the printer unit 1 opposes the cutout portion 53 provided in the first sheath portion 50 of the sheet package 9 (see FIGS. 3 , 4 ). Therefore, when any sheets 7 are present in the sheet package 9, the reflection type optical sensor 80 detects reflection light from a sheet 7 and when no sheet 7 is present, it detects reflection light from a synthetic resin which constitutes the rear face of the lid body 10.
- the ear portions 71 and 72 are located in space sandwiched by the bottom portion 40 (the first portion) and the first sheath portion 50 (the second portion) as shown in FIG. 22 and the side ends of the ear portions 71 and 72 make contact with the end portions of the sheets 7 in an insertion direction, and the end portions of the sheets 7 are consequently unable to contact with the side wall portion 43. Therefore, the sheets 7 cannot be restored to their original positions in the sheet package 9 as shown in FIG. 22 and consequently, part of the sheets 7 project from the sheet package 9. Thus, the dropped sheets 7 cannot be restored to their normal storage positions in the sheet package 9 through the opening portion 49, thereby preventing sheets 7 to which dust or dirt has adhered from being used again.
- the package material 8 of the sheet package 9 of the second embodiment is provided with a tongue portion 70 which is rectangular.
- the ear portions 73 and 74 which are rectangular, are provided in a central portion in a longitudinal direction of the tongue portion 70 with a cut line (straight) and a fold line (two-dot and chain line) .
- a cut line straight
- a fold line two-dot and chain line
- the ear portions 73 and 74 press against the sheets 7, thereby producing identical operations and effects to those in the first embodiment.
- a third embodiment of the sheet package 9 will now be described with reference to FIG. 25 .
- the package material 8 of the sheet package 9 of the third embodiment is provided with a tongue portion 70 which is rectangular, ear portions are not provided on the tongue portion 70.
- the ear portions 47 and 48 which is rectangular are provided on the bottom portion 40 with a cut line (straight) and a fold line (two-dot and chain line). Therefore, before the sheets 7 are loaded on the bottom portion 40 as the first portion, the ear portions 47 and 48 of the bottom portion 40 are raised and folded back and then sheets 7 are loaded thereon. Consequently, the ear portions 47 and 48 press the sheets 7, thereby producing identical operations and effects to those of the first embodiment.
- the package material 8 of the sheet package 9 of the fourth embodiment is provided with the tongue portion 70 which is rectangular as shown in FIG. 26 , the ear portion is not provided on the tongue portion 70.
- the ear portions 57 and 58 which are rectangular are provided on the first sheath portion 50 as the first portion with a cut line (straight) and a fold line (two-dot and chain line) provided. Therefore, sheets 7 are loaded on the bottom portion 40, and before the first sheath portion 50 is folded back, the ear portions 57 and 58 are raised and folded back. When the first sheath portion 50 is folded, the ear portions 57 and 58 press against the sheets 7, thereby producing identical operations and effects to those in the first embodiment.
- a fifth embodiment of the sheet package 9 will be described with reference to FIG. 27 .
- Substantially every configuration of the package material 8 of the sheet package 9 of the fifth embodiment is identical to the package material 8 of the first embodiment as shown in FIG. 8 .
- the different point is that a boundary line 401 between the bottom portion 40 and the side wall portion 41, a boundary line 402 between the bottom portion 40 and the side wall portion 42, and a boundary line 403 between the bottom portion 40 and the side wall portion 43 are perforated.
- the fold line processing with half-round shape embossing is processed on the boundary line in the package material 8.
- the fold line processing with half-round shape embossing is performed from the outer side to the inner side in assembling the package material 8.
- the boundary line is facilitated to fold by the fold line processing.
- an embossment portion 410 is formed on the inner side of the fold line along the fold line (See FIG.30 ).
- the boundary line 401 between the bottom portion 40 and the side wall portion 41, the boundary line 402 between the bottom portion 40 and the side wall portion 42, and the boundary line 403 between the bottom portion 40 and the side wall portion 43 are processed with the ordinary fold line processing with half-round shape embossing.
- the embossment portion 410 is formed on the inner side of the fold line along the fold line (See FIG.30 ). That is because the inner part of the fold line is compressed when the boundary line is folded, and the inner part need the releasing portion of the compression to bulge.
- Some fiber of the package material 8 is unraveled within the embossment portion, and the fiber density is slightly less than other portions.
- the bottom portion 40 is situated next to the embossment portion 410 formed on the boundary line 401.
- a space 411 is formed between the bottom portion 40 and the embossment portion 410.
- the sheet 7 can be wedged in the space 411. The same goes for the space formed between the bottom portion 40 and the boundary line 402, and the space between the bottom portion 40 and the boundary line 403. Once the sheet is wedged in the space, the wedged sheet may not be ejected by operating the printer unit 1.
- the sheet that may be wedged is only the sheet 7 located on the bottommost layer of the stacked sheets opposing to the bottom portion 40. As described before, a face provided in the package material 8 to wedge the sheet 7 and the embossment portion adjacent to the face are needed for wedging the sheet 7.
- the sheet 7 is wedged easily if the sheet 7 contacts the face in parallel.
- the sheet 7 can be wedged easily if the edge of the sheet 7 contacts parallel with the linear embossment portion 410.
- the size of the sheet storage portion 6 in present embodiment as seen in a plan view is almost the same as that of the sheet 7 stored in it. Because the each edge of the sheet 7 is regulated by the inner wall of the sheet storage portion 6 or by the side wall of the package material 8, the edge of the sheet 7 contacts the linear embossment portion 410 easily in parallel with the linear embossment portion 410.
- the sheet 7 located on the bottommost layer is pressed to the bottom portion 40 by the effect of gravitation, by the effect of urging the sheet 7 in a downward direction by the ear portions 71 and 72 at the upstream of conveyance direction of the sheet, and by the effect of urging the sheet 7 in a downward direction by the urging spring 19 at the downstream of conveyance direction of the sheet, the sheet 7 is wedged easily. Even in the bottommost sheet 7, the part urged in a downward direction is more inclined to be wedged than the part not urged in a downward direction.
- the sheet package 9 provides the lid base portion 44a which is folded back to the rear side when the sheet package 9 is loaded to the sheet storage portion 6.
- the length of the lid base portion 44a in conveyance direction is approximately one-third of the length of the sheet package 9 in conveyance direction.
- the bottom portion 40 is formed shortly for the lid base portion 44a, and the side walls are formed in some part of the bottom portion 40, there is no fold line parallel to the conveyance direction of the sheet and is no the embossment portion in the one-third length portion from the end of the downstream to the upstream side in conveyance direction on the bottom face in the sheet package 9.
- the urging spring 19 is structured so as to urge the sheet 7 strongly in a downward direction at the end of the downstream of conveyance direction in the sheet package 9 and urge the sheet 7 weakly as toward to the upstream. Therefore, the potential of being wedged the sheet 7 due to urging the sheet 7 in a downward direction by the urging spring 19 at the downstream of conveyance direction of the sheet is smaller than the potential of being wedged the sheet 7 due to urging the sheet 7 in a downward direction by the ear portions 71 and 72 at the upstream of conveyance direction of the sheet.

Abstract
Description
- The present invention relates to a sheet package, and more particularly to a sheet package that protects the outside of a stack of sheets with its package member and that can be set in a printer unit together with a package material.
- Conventionally, there has been known a sheet package which accommodates a stack of sheets in its box-like package member and which, when the sheets are used for printing can be set in a printer unit by opening the lid portion of the package member and by folding it back to the opposite side, see, for example,
Japanese Patent Application Publication No.2003-285939 US2005/0230902 A1 ) which forms the basis for the preamble ofclaims - However, in the case of a conventional sheet package, when at a time of usage a part of the sheets is exposed, as a result of the opening of the lid portion, sometimes sheets stored inside the sheet package can drop out of the sheet package. In such circumstances, if printing is executed by setting a sheet package in which the dropped sheets are inserted because the dropped sheets can be brought back into the sheet package easily through an opening portion, impurities such as dust and dirt adhere to the sheet tend to damage a printing head of the printer unit.
- Further, because the conventional sheet package has no pressing means for supporting sheets contained in the interior, when the opening portion of a sheet package is directed in a downward direction during the handling of a sheet package, sheets can drop out.
- The present invention has been accomplished to solve the above-described problems and a first object of the invention is to prevent sheets taken out from the sheet package temporarily from being inserted back into their original storage position within the sheet package. Further, a second object of the invention is to achieve a sheet package out of which sheets do not drop.
- In order to achieve the above-described objects, according to an aspect of the present invention, there is provided a sheet package as claimed in

sheet package 9 is to be loaded according to a first embodiment of the present invention will be described with reference toFIGS. 1-4 . - As shown in
FIG. 1 , theprinter unit 1 is formed into a flat type rectangular parallelpiped configuration approximately 2 cm in thickness, while its rectangular shape as seen in a plan view is slightly larger than A6 size. Amain body case 2 which constitutes a casing of theprinter unit 1 is comprised of aframe body 3, alower cover 4, anupper cover 5, alid body 10 and the like. Theframe body 3 constitutes a frame of theprinter unit 1, presenting a rectangular shape as seen in its plan view. Thelower cover 4 covers the bottom face of theframe body 3, presenting a rectangular shape as seen in its plan view. Theupper cover 5 covers part of the top face of theframe body 3. Thelid body 10 is structured so as to be capable of being opened and closed. - As shown in
FIGS. 2 and3 , aprinting mechanism portion 14 is incorporated inside an end portion (upper side inFIGS. 2 and3 ) of theprinter unit 1 and the rectangularupper cover 5 as seen in its plan view is provided in such a way as to cover its top face. Asheet storage portion 6 is formed in the remaining portion of the top face of theframe body 3 that excludes the portion covered by theupper cover 5. The top of thesheet storage portion 6 is covered by therectangular lid body 10 as seen in its plan view. Thelid body 10 can be opened and closed freely as shown inFIG. 2 . - The
sheet storage portion 6 can accommodate asheet package 9 in which a plurality ofsheets 7, for example A6 or A7 sized cut-sheet type heat sensitive papers, can be stored inside apackage material 8, as shown inFIG. 3 . Themain body case 2 is equipped with a locking mechanism (not shown), and when asheet package 9 set in thesheet storage portion 6, thelid body 10 can be closed and locked as shown inFIG. 3 . - A
pickup roller 12, aseparation block 13 and the like are disposed as a sheet-separatingportion 11 at an end portion on theprinting mechanism portion 14 side of thesheet storage portion 6. Athermal head 15, aplaten roller 16 and apaper guide 17 are disposed as aprinting mechanism portion 14 below theupper cover 5. - The
paper separation portion 11 will next be described with reference toFIG. 4 . As shown inFIG. 4 , thepickup roller 12 and theseparation block 13 are provided at an end portion on a side close to theprinting mechanism portion 14 of thesheet storage portion 6. At such an inner face of thelid body 10 as to face thesheet storage portion 6, apressing plate 18 is supported in condition where it can swing. A coil-like urging spring 19 is interposed between thepressing plate 18 and thelid body 10 so as to apply constantly to thepressing plate 18 an urging force in a direction of the rotation of thepressing plate 18 in a downward direction. - The
sheet package 9 is loaded into thesheet storage portion 6 with the printing object faces of thesheets 7 being directed in a downward direction, and in a state in which a bottom face of asheet 7 located at the bottommost position ofsheets 7 stored in thesheet package 9 in a stacked condition is exposed partly from thepackage material 8. Then, when thelid body 10 is closed and locked, thepressing plate 18 urged by the urgingspring 19 in a downward direction presses the exposed portion of thesheet 7 against thepickup roller 12 through thepackage material 8 so that the bottom face of thesheet 7 is brought into contact with thepickup roller 12. - As shown in
FIG. 4 , theseparation block 13 which constitutes the sheet-separatingportion 11 is provided such that it is located in the vicinity of and opposes thepickup roller 12. Theseparation block 13 has aseparation guide face 13a which is inclined with respect to a direction of feeding sheets by thepickup roller 12. In a sheet-separatingportion 11 having such a structure, thepickup roller 12 is driven so that a frictional transportation force is applied to thesheet 7 that is located on the bottommost layer and that is in contact with thepickup roller 12. Then, only thesheet 7 located on the bottommost layer is separated and fed by the separating action of theseparation guide face 13a of theseparation block 13 in tandem with the frictional transportation force. - Next, the
printing mechanism portion 14 will be described. As shown inFIG. 4 , theplaten roller 16 is provided being driven rotatably by a motor (not shown) on the opposite side to thepickup roller 12 across theseparation block 13, and thepaper guide 17 is disposed in the vicinity of the outer peripheral face of theplaten roller 16. Thepaper guide 17 has a concavely curved slidingcontact face 17a that possesses a substantially U-shaped section as seen in a lateral direction, and thepaper guide 17 is provided so as to extend along the outer peripheral face of thecylindrical platen roller 16. Apressing coil spring 20 is provided between thepaper guide 17 and themain body case 2 so as to urge the slidingcontact face 17a toward the outer peripheral face of theplaten roller 16. - In a
printer unit 1 having such a structure, asheet 7 separated by the sheet-separatingportion 11 is conveyed by thepickup roller 12 and passes between the bottom end of theseparation block 13 and aguide plate 21 that guides the sheet in the direction of theplaten roller 16. Thesheet 7 is guided by theguide plate 21 and guided from the bottom side of theplaten roller 16 to a portion between theplaten roller 16 and thepaper guide 17. Thesheet 7 is held between the outer peripheral face of theplaten roller 16 and the slidingcontact face 17a of thepaper guide 17 and conveyed in a state in which it is inverted into a U shape as seen in a lateral direction by a rotation of theplaten roller 16. The sheet accordingly reaches the top side of theplaten roller 16 with its printing object face facing an upward direction. - As shown in
FIG. 4 , thethermal head 15 that is located above theplaten roller 16 has a heat-generatingbody portion 15a. Thethermal head 15 is provided rotatably around arotation shaft 15b, and the heat generatingbody portion 15a is configured in such a way as to be capable of making contact with, and moving away from, the top face of theplaten roller 16. The reason why thethermal head 15 is configured in such a way as to be rotatable is that in removing a jammed paper when asheet 7 is jammed between theplaten roller 16 and thepaper guide 17, thethermal head 15 is in this way prevented from becoming an impediment to that removal work. - As shown in
FIG. 4 , an end of a torsioncoil type spring 22 is attached to thethermal head 15 so as to always apply an urging force constantly in a direction in which the heat-generatingbody portion 15a of thethermal head 15 is made to approach the top face of theplaten roller 16. With this configuration, the heat-generatingbody portion 15a of thethermal head 15 makes contact with the top face of asheet 7 conveyed by theplaten roller 16 with its printing object face directed in an upward direction and, thesheet 7 is then printed at the position where contact is made. - The
thermal head 15 is of a line head type and can accordingly print any character or image on each individual line extending in a direction perpendicular to the conveyance direction of thesheet 7 on the conveyed heatsensitive type sheet 7. A printing width at the time that printing is performed on a single line is set so as to substantially equal to the width of thepaper 7 which is a printing object. Because thethermal head 15 is used as a printing head, a heat sensitive paper is used as a printing object medium and thus, consumables such as ink and ink ribbon are reduced. Further, a mechanism for supplying ink can be abolished, thereby resulting in a compact structure of theprinter unit 1. As the heat sensitive paper, heat sensitive coloring type having a coloring layer which generates color when heated by thethermal head 15, and a heat sensitive boring type in which a boring layer is overlaid on a base material layer and in which, the boring layer being bored when heated and other types are available. - A sheet
discharge guide face 13b, which is inclined with respect to a sheet-feeding direction of theplaten roller 16, is formed on theseparation block 13. With this structure, asheet 7 after printed by the heat-generatingbody portion 15a of thethermal head 15 is guided by the sheetdischarge guide face 13b and discharged to the top of thelid body 10 through a slit defined by theupper cover 5 of themain body case 2 and thelid body 10 as shown inFIG.1 . - Next, a
sheet package 9 of the first embodiment of the present invention to be set in theprinter unit 1 will be described with reference toFIGS. 5-14 . - As shown in
FIG. 5 , thesheet package 9 is made up of thepackage material 8 which is folded into a rectangular parallelepiped thin box. Thesheet package 9 contains a plurality of sheets (recording object mediums) 7 composed of, for example, A6-A7 size cut-sheet like heat sensitive papers in a stacked condition. Users purchasesheet packages 9 that are put on sale in a box type condition shown inFIG. 5 . And as shown inFIGS. 6 and7 , alid portion 44 is opened and folded back to the rear side. Aninsert section 44d of thelid portion 44 is inserted into athird slit 45 in abottom portion 40, which will be described later so as to exposesheets 7 located on the inside. Then, the user sets the sheets together with thepackage material 8 in thesheet storage portion 6 of theprinter unit 1 and uses. - Next, the structure of the
package material 8 will be described with reference toFIGS. 8 and9 . As shown inFIGS. 8 and9 , thepackage material 8 is formed by punching out a flat thick paper. Therectangular bottom portion 40 as the first portion, for covering one face in a stack direction of thestacked sheets 7 is provided in the central portion of thepackage material 8. For convenience for explanation, the lid side in a discharge direction of thesheet 7 in thesheet package 9, that is, right side inFIG. 8 of thepackage material 8 is defined to be front side and the left side on opposite side is defined to be rear side. A rectangularside wall portion 41 as the third portion, which is rectangular, and is extended from one of a pair of side end portions of thebottom portion 40. A rectangularside wall portion 42 as the fourth portion, is extended from the other side end portion. A rectangularside wall portion 43 as the fifth portion, is extended from the rear end portion of thebottom portion 40. Theside wall portion 43 receives the bottom end portion of thesheets 7 when thesheet package 9 is assembled. The heights of the side wall portions 41-43 (width in short side direction) are all the same and larger than the stack height of thesheets 7 stored in thesheet package 9. - As shown in
FIGS. 8 and9 , thelid portion 44 is extended from the front end side of thebottom portion 40. Thelid portion 44 is comprised of alid base portion 44a, a lidside wall portion 44b, a lidfront end portion 44c and theinsert section 44d. Thelid base portion 44a is formed in a rectangular shape. The lidside wall portion 44b is formed in a rectangular shape and is extended from thelid base portion 44a, having the same height (width in a short side direction) as the heights of theside wall portions 41 to 43. The lidfront end portion 44c is extended from the lidside wall portion 44b and a width thereof is smaller than that of the lidside wall portion 44b. Theinsertion portion 44d is extended from the lidfront end portion 44c and a width thereof is smaller than the lidfront end portion 44c. A pair of inclined sides is provided at the front end of theinsertion portion 44d. A shape that is formed by a combination of thebottom portion 40 and thelid base portion 44a is substantially the same shape as asheet 7. - As shown in
FIGS. 8 and9 , a rectangularfirst sheath portion 50 as the second portion, for covering thesheets 7 in such a way that it opposes thebottom portion 40 after assembly is extended from theside wall portion 41 of thebottom portion 40. Thefirst sheath portion 50 has afirst slit 51 in which theinsert section 44d of thelid portion 44 is inserted and asecond slit 52 in which aninsert section 61 of asecond sheath portion 60 is inserted. Asquare cutout portion 53 for detecting the presence/absence of asheet 7 is provided in a side end portion on thelid base portion 44a side of thefirst sheath portion 50. Theprinter unit 1 detects the presence/absence of asheet 7 with the use of thecutout portion 53. In other words, thesheet package 9 is loaded in thesheet storage portion 6 of theprinter unit 1 in the state shown inFIG. 6 , and theprinter unit 1 is provided with a reflection type optical sensor 80 (seeFIGS. 3 and4 ) at a position opposite to thecutout portion 53. Thus, when anysheets 7 are present in thesheet package 9, the reflection typeoptical sensor 80 detects reflection of light from thesheets 7 and if nosheet 7 is present, the reflection type optical sensor detects reflection light from a synthetic resin which constitutes the rear face of thelid body 10. Therefore, if as the color of the synthetic resin which constitutes thesheet storage portion 6, a color having a low reflectance ratio is set, the presence/absence of a sheet can be easily detected. - As shown in
FIG. 8 , threesensor marks 46 which indicate the type and size ofsheets 7 stored in thesheet package 9 are printed on an end portion on thefirst sheath portion 50 side of thebottom portion 40 on the front side (outer side) of thepackage material 8. These sensor marks 46 are read by a reflection type optical sensor (a sensor (not shown) that is different from the reflection type optical sensor 80), and that is provided on theprinter unit 1. For example, if asensor mark 46 is printed, it is regarded as "1", and thesensor mark 46 is not printed, it is regarded as "0", then the absence of a sheet and seven different types ofsheets 7 can be identified with the combination of presence or absence of the three sensor marks 46. Thebottom portion 40 is provided with athird slit 45 in which theinsert section 44d of a folded backlid portion 44 is to be inserted. Further, a cut-inportion 54 which is cut to a predetermined length from thecutout portion 53 side is provided between theside wall portion 41 and thefirst sheath portion 50. The cut-inportion 54 facilitates deflection of thefirst sheath portion 50 when thefirst sheath portion 50 is pressed if thesheet package 9 is loaded on thesheet storage portion 6. - As shown in
FIGS. 8 and9 , asecond sheath portion 60 for fixing thefirst sheath portion 50 for covering thesheets 7 in such a way that it opposes thebottom portion 40 after assembly is provided so as to extend as far asside wall portion 42 of thebottom portion 40. The width of thesecond sheath portion 60 is smaller than that of thefirst sheath portion 50 and aninsert section 61 is formed on a side end portion of thesecond sheath portion 60. When thesheet package 9 is assembled, theinsert section 61 is inserted into thesecond slit 52 in thefirst sheath portion 50 so as to fix thefirst sheath portion 50 opposing to thebottom portion 40. - As shown in
FIGS. 8 and9 , atongue portion 70 as the sixth portion, which is rectangular, is extended from theside wall portion 43 of thebottom portion 40.Rectangular ear portions tongue portion 70. When theear portions FIGS. 8 and9 is a portion that is subjected to fold line processing and the fold line facilitates folding of a thick paper for convenience of assembly. - Next, a manufacturing process of the
sheet package 9 will be described with reference toFIGS. 10 to 14 . As shown inFIG. 10 , theear portions tongue portion 70 are folded back and thestacked sheets 7 are loaded on thebottom portion 40. Next, as shown inFIG. 11 , thetongue portion 70 of thepackage material 8 is fold over. Next, as shown inFIG. 12 , thefirst sheath portion 50 is folded in such a way that it overlaps with the top of thetongue portion 70 and as shown inFIG. 13 , thesecond sheath portion 60 is folded over thefirst sheath portion 50. Next, theinsert section 61 of thesecond sheath portion 60 is inserted into thesecond slit 52 in thefirst sheath portion 50. - Finally, as shown in
FIG. 14 , thelid portion 44 is folded over thefirst sheath portion 50, theinsert section 44d of thelid portion 44 is inserted into thefirst slit 51 in thefirst sheath portion 50, and the sheet package is thus completed.Sheet packages 9 are sold in this condition. Because this condition allows theear portions sheet package 9, they press against the surface of thestacked sheets 7. - Next, a method of using the
sheet package 9 will be described with reference toFIGS. 3 ,5 ,6 ,7 ,15 ,16 and17 . When asheet package 9 is used, thelid portion 44 of thesheet package 9 in the state shown inFIG. 5 is erected as shown inFIG. 15 and folded back to the rear side along the line II-II inFIG. 16 . Then, as shown inFIG. 7 , theinsert section 44d of the lidfront end portion 44c of thelid portion 44 is inserted into thethird slit 45 of thebottom portion 40 and thelid portion 44 is fixed to thebottom portion 40. Consequently, as shown inFIG. 6 , thesheet package 9 reverts to a state in which the front end portion of thesheets 7 is exposed. Thesheet package 9 in this state is stored in thesheet storage portion 6 of theprinter unit 1 as shown inFIG. 3 . When thelid body 10 is closed, thefirst sheath portion 50 of thesheet package 9 is pressed by thepressing plate 18 and the sheet that is located on the bottommost layer of thestacked sheets 7 is pressed against thepickup roller 12. - At this time, the reflection type
optical sensor 80 that is provided on theprinter unit 1 opposes thecutout portion 53 provided in thefirst sheath portion 50 of the sheet package 9 (seeFIGS. 3 ,4 ). Therefore, when anysheets 7 are present in thesheet package 9, the reflection typeoptical sensor 80 detects reflection light from asheet 7 and when nosheet 7 is present, it detects reflection light from a synthetic resin which constitutes the rear face of thelid body 10. - Next, an action of a sheet intrusion blocking member (
ear portions 71 and 72) of the present invention will be described with reference toFIGS. 6 ,16 to 22 . - When the
lid portion 44 of thesheet package 9 is folded back as shown inFIGS. 6 and16 , in thesheet package 9, theear portions tongue portion 70 press against the surface of thesheet 7 stored in thesheet package 9 as shown inFIG. 18 (see alsoFIG. 11 ). The pressing force of theear portions ear portions package material 8. When the quantity of sheets stored in thesheet package 9 is small, theear portions sheet 7 as shown inFIG. 19 . Therefore, when thelid portion 44 of thesheet package 9 is folded back,sheets 7 can be prevented from dropping out of thesheet package 9. - In circumstances such as when all
sheets 7 have been pulled out from thesheet package 9 by a user, or when a user swings thesheet package 9 with an opening portion 49 (seeFIG. 21 ) facing downwards with folding back thelid portion 44, all thesheets 7 might drop out from thesheet package 9. In such circumstances, theear portions package 8 along the fold line as shown inFIG. 20 , so that the front ends of theear portions bottom portion 40. In this state, ifsheets 7 are inserted into thesheet package 9 through the openingportion 49 as shown inFIG. 21 , theear portions FIG. 22 and the side ends of theear portions sheets 7 in an insertion direction, and the end portions of thesheets 7 are consequently unable to contact with theside wall portion 43. Therefore, thesheets 7 cannot be restored to their original positions in thesheet package 9 as shown inFIG. 22 and consequently, part of thesheets 7 project from thesheet package 9. Thus, the droppedsheets 7 cannot be restored to their normal storage positions in thesheet package 9 through the openingportion 49, thereby preventingsheets 7 to which dust or dirt has adhered from being used again. - Next, a second embodiment of the
sheet package 9 will be described with reference toFIGS. 23 and24 . - Because substantially every configuration of the
package material 8 of thesheet package 9 of the second embodiment is identical to the package material of the first embodiment as shown inFIG. 23 , only different portions will be described. As shown inFIG. 23 , thepackage material 8 of thesheet package 9 of the second embodiment is provided with atongue portion 70 which is rectangular. Theear portions tongue portion 70 with a cut line (straight) and a fold line (two-dot and chain line) . When theear portions ear portions tongue portion 70 is raised and folded and theear portions FIG. 24 , theear portions sheets 7, thereby producing identical operations and effects to those in the first embodiment. - A third embodiment of the
sheet package 9 will now be described with reference toFIG. 25 . - Because substantially every configuration of the
package material 8 of thesheet package 9 of the third embodiment is identical to the package material of the first embodiment as shown inFIG. 25 , only different portions will be described. Although as shown inFIG. 25 , thepackage material 8 of thesheet package 9 of the third embodiment is provided with atongue portion 70 which is rectangular, ear portions are not provided on thetongue portion 70. According to the third embodiment, theear portions bottom portion 40 with a cut line (straight) and a fold line (two-dot and chain line). Therefore, before thesheets 7 are loaded on thebottom portion 40 as the first portion, theear portions bottom portion 40 are raised and folded back and thensheets 7 are loaded thereon. Consequently, theear portions sheets 7, thereby producing identical operations and effects to those of the first embodiment. - Next, a fourth embodiment of the
sheet package 9 will be described with reference toFIG. 26 . - Because substantially every configuration of the
package material 8 of thesheet package 9 of the fourth embodiment is identical to the package material of the third embodiment as shown inFIG. 26 , only different portions will be explained. Although thepackage material 8 of thesheet package 9 of the fourth embodiment is provided with thetongue portion 70 which is rectangular as shown inFIG. 26 , the ear portion is not provided on thetongue portion 70. According to the fourth embodiment, theear portions first sheath portion 50 as the first portion with a cut line (straight) and a fold line (two-dot and chain line) provided. Therefore,sheets 7 are loaded on thebottom portion 40, and before thefirst sheath portion 50 is folded back, theear portions first sheath portion 50 is folded, theear portions sheets 7, thereby producing identical operations and effects to those in the first embodiment. - Next, a fifth embodiment of the
sheet package 9 will be described with reference toFIG. 27 . Substantially every configuration of thepackage material 8 of thesheet package 9 of the fifth embodiment is identical to thepackage material 8 of the first embodiment as shown inFIG. 8 . The different point is that aboundary line 401 between thebottom portion 40 and theside wall portion 41, aboundary line 402 between thebottom portion 40 and theside wall portion 42, and aboundary line 403 between thebottom portion 40 and theside wall portion 43 are perforated. - Ordinarily, the fold line processing with half-round shape embossing is processed on the boundary line in the
package material 8. The fold line processing with half-round shape embossing is performed from the outer side to the inner side in assembling thepackage material 8. The boundary line is facilitated to fold by the fold line processing. When the boundary line processed with the fold line processing by embossing is fold, anembossment portion 410 is formed on the inner side of the fold line along the fold line (SeeFIG.30 ). Theboundary line 401 between thebottom portion 40 and theside wall portion 41, theboundary line 402 between thebottom portion 40 and theside wall portion 42, and theboundary line 403 between thebottom portion 40 and theside wall portion 43 are processed with the ordinary fold line processing with half-round shape embossing. When each of theboundary lines embossment portion 410 is formed on the inner side of the fold line along the fold line (SeeFIG.30 ). That is because the inner part of the fold line is compressed when the boundary line is folded, and the inner part need the releasing portion of the compression to bulge. Some fiber of thepackage material 8 is unraveled within the embossment portion, and the fiber density is slightly less than other portions. Thebottom portion 40 is situated next to theembossment portion 410 formed on theboundary line 401. Aspace 411 is formed between thebottom portion 40 and theembossment portion 410. Thesheet 7 can be wedged in thespace 411. The same goes for the space formed between thebottom portion 40 and theboundary line 402, and the space between thebottom portion 40 and theboundary line 403. Once the sheet is wedged in the space, the wedged sheet may not be ejected by operating theprinter unit 1. The sheet that may be wedged is only thesheet 7 located on the bottommost layer of the stacked sheets opposing to thebottom portion 40. As described before, a face provided in thepackage material 8 to wedge thesheet 7 and the embossment portion adjacent to the face are needed for wedging thesheet 7. Thesheet 7 is wedged easily if thesheet 7 contacts the face in parallel. Thesheet 7 can be wedged easily if the edge of thesheet 7 contacts parallel with thelinear embossment portion 410. In that respect, the size of thesheet storage portion 6 in present embodiment as seen in a plan view is almost the same as that of thesheet 7 stored in it. Because the each edge of thesheet 7 is regulated by the inner wall of thesheet storage portion 6 or by the side wall of thepackage material 8, the edge of thesheet 7 contacts thelinear embossment portion 410 easily in parallel with thelinear embossment portion 410. Since thesheet 7 located on the bottommost layer is pressed to thebottom portion 40 by the effect of gravitation, by the effect of urging thesheet 7 in a downward direction by theear portions sheet 7 in a downward direction by the urgingspring 19 at the downstream of conveyance direction of the sheet, thesheet 7 is wedged easily. Even in thebottommost sheet 7, the part urged in a downward direction is more inclined to be wedged than the part not urged in a downward direction. - However, the
sheet package 9 provides thelid base portion 44a which is folded back to the rear side when thesheet package 9 is loaded to thesheet storage portion 6. The length of thelid base portion 44a in conveyance direction is approximately one-third of the length of thesheet package 9 in conveyance direction. Sine thebottom portion 40 is formed shortly for thelid base portion 44a, and the side walls are formed in some part of thebottom portion 40, there is no fold line parallel to the conveyance direction of the sheet and is no the embossment portion in the one-third length portion from the end of the downstream to the upstream side in conveyance direction on the bottom face in thesheet package 9. The urgingspring 19 is structured so as to urge thesheet 7 strongly in a downward direction at the end of the downstream of conveyance direction in thesheet package 9 and urge thesheet 7 weakly as toward to the upstream. Therefore, the potential of being wedged thesheet 7 due to urging thesheet 7 in a downward direction by the urgingspring 19 at the downstream of conveyance direction of the sheet is smaller than the potential of being wedged thesheet 7 due to urging thesheet 7 in a downward direction by theear portions - Compared with the
package material 8 processed with the ordinary fold line processing, thepackage material 8 in the present embodiment provides the perforated lines on theboundary line 401 between thebottom portion 40 and theside wall portion 41, theboundary line 402 between thebottom portion 40 and theside wall portion 42, and theboundary line 403 between thebottom portion 40 and theside wall portion 43, as described before. For example, as shown inFIG.31 , aperforated line 412 facilitates folding of theside wall 41 to thebottom portion 40, and the embossment portion is not formed on the inner side of the fold line folded at the boundary line processed with the perforated line. Theperforated line 412 facilitates folding of theside walls bottom portion 40, and the embossment portion is not formed on the inner side of the fold line folded at the boundary line processed with the perforated line, as the same as above. As a result, unlike thesheet package 9 with the ordinary fold line processing, thesheet package 9 in the present embodiment can prevent thesheet 7 located on the bottommost layer of the stacked sheets opposing to thebottom portion 40 from being wedged in the boundary line between thebottom portion 40 and theside wall portion 41, the boundary line between thebottom portion 40 and theside wall portion 42, or the boundary line between thebottom portion 40 and theside wall portion 43.
In thepackage material 8 in the fifth embodiment (seeFIG. 27 ), aboundary line 404 between thefirst sheath portion 50 and theside wall portion 41, aboundary line 405 between thesecond sheath portion 60 and theside wall portion 42, and a boundary line 406 between thetongue portion 70 and theside wall portion 43 are processed with the ordinary fold line processing with half-round shape embossing. - In the
sheet package 9 of the present embodiment, the perforated lines are provided on theboundary line 401 between thebottom portion 40 and theside wall portion 41, theboundary line 402 between thebottom portion 40 and theside wall portion 42, and theboundary line 403 between thebottom portion 40 and theside wall portion 43. The perforated lines may be provided on only theboundary line 403 that is the border with thebottom portion 40 opposing theear portions sheet 7 and where thesheet 7 is urged strongly by theear portions bottom portion 40 opposing theear portions sheet 7 and that is adjacent to theear portions boundary line 403. The perforated lines may be provided on the portion that is the end of the upstream of conveyance direction of thesheet 7 in theboundary line 402 with thebottom portion 40 opposing theear portion 71 through thesheet 7 and that is adjacent to theear portion 71 in theboundary line 402, the portion that is the end of the upstream of conveyance direction of thesheet 7 in theboundary line 401 and that is adjacent to theear portion 72 in theboundary line 401 with thebottom portion 40 opposing theear portion 72 through thesheet 7, and theboundary line 403. - Next, a sixth embodiment of the
sheet package 9 will be described with reference toFIG. 28 . The object of thesheet package 9 in the present embodiment is to prevent thesheet 7 located on the bottommost layer of the stacked sheets opposing to thebottom portion 40 from being wedged in the boundary line between thebottom portion 40 and theside wall portion 41, the boundary line between thebottom portion 40 and theside wall portion 42, and the boundary line between thebottom portion 40 and theside wall portion 43, as the same as thesheet package 9 in the fifth embodiment. Substantially every configuration of thepackage material 8 of thesheet package 9 of the sixth embodiment is identical to thepackage material 8 of the first embodiment as shown inFIG. 8 . As shown inFIG.28 , the different point is that theboundary line 401 between thebottom portion 40 and theside wall portion 41, theboundary line 402 between thebottom portion 40 and theside wall portion 42, and theboundary line 403 between thebottom portion 40 and theside wall portion 43 are processed with half-cut processing on each inner side of theboundary line side wall portions package material 8. With the half-cut processing, theside wall portions bottom portion 40 easily and thesheet 7 located on the bottommost layer of the stacked sheets opposing to thebottom portion 40 is prevented from being wedged in theboundary line 401 between thebottom portion 40 and theside wall portion 41, theboundary line 402 between thebottom portion 40 and theside wall portion 42, and theboundary line 403 between thebottom portion 40 and theside wall portion 43 because the boundary lines between theside wall portions bottom portion 40 are folded closely to thebottom portion 40. In thepackage material 8 of the sixth embodiment, theboundary line 404 between thefirst sheath portion 50 and theside wall portion 41, theboundary line 405 between thesecond sheath portion 60 and theside wall portion 42, and the boundary line 406 between thetongue portion 70 and theside wall portion 43 are processed with the ordinary fold line processing with half-round shape embossing. - Next, a seventh embodiment of the
sheet package 9 will be described with reference toFIG. 29 . The object of thesheet package 9 in the present embodiment is to prevent thesheet 7 located on the bottommost layer of the stacked sheets opposing to thebottom portion 40 from being wedged in the boundary line between thebottom portion 40 and theside wall portion 41, the boundary line between thebottom portion 40 and theside wall portion 42, and the boundary line between thebottom portion 40 and theside wall portion 43, as the same as thesheet package 9 in the fifth embodiment. Substantially every configuration of thepackage material 8 of thesheet package 9 of the seventh embodiment is identical to thepackage material 8 of the first embodiment as shown inFIG. 8 . The different point is that pit-like indentations with predetermined depth are provided in line on theboundary line 401 between thebottom portion 40 and theside wall portion 41, theboundary line 402 between thebottom portion 40 and theside wall portion 42, and theboundary line 403 between thebottom portion 40 and theside wall portion 43, as shown inFIG.29 . By the fold line processing with pits, theside wall portions bottom portion 40 easily and thesheet 7 located on the bottommost layer of the stacked sheets opposing to thebottom portion 40 is prevented from being wedged in theboundary line 401 between thebottom portion 40 and theside wall portion 41, theboundary line 402 between thebottom portion 40 and theside wall portion 42, and theboundary line 403 between thebottom portion 40 and theside wall portion 43. In thepackage material 8 of the seventh embodiment, theboundary line 404 between thefirst sheath portion 50 and theside wall portion 41, theboundary line 405 between thesecond sheath portion 60 and theside wall portion 42, and the boundary line 406 between thetongue portion 70 and theside wall portion 43 are processed with the ordinary fold line processing with half-round shape embossing. The above described terms "perforated line", "half-cut processing" and "pit-like indentation" correspond to the indentation portion. - The present invention is not limited to the above-described embodiments but may be modified in various ways. For example, a single ear portion is permitted instead of a pair of ear portions on the right and left sides. The shape of the ear portion is not limited to a rectangular one but may be of any shape such as trapezoid. Although, according to the embodiments, the
side wall portion 42 is extended from thebottom portion 40, theside wall portion 42 may also be extended from thefirst sheath portion 50, while thesecond sheath portion 60 may be extended from theside wall portion 42. Although according to the embodiments, theside wall portion 43 is extended from thebottom portion 40, theside wall portion 43 may also be extended from thefirst sheath portion 50, while thetongue portion 70 may be extended from theside wall portion 43. The term "perforated line", "half-cut processing" and "pit-like indentation" are not necessary to be provided on whole of theboundary line 401 between the 40 and the 41, theboundary line 402 between the 40 and the 42, and theboundary line 403 between the 40 and the 43. For example, they may be provided on only the portion where thesheet 7 is wedged easily and other portions may be processed with the ordinary fold processing with half-round shape embossing. As portions where thesheet 7 is wedged easily are the boundary line between thebottom portion 40 and theside wall portion 41, the boundary between line thebottom portion 40 and theside wall portion 42 which opposes to front side of thefirst sheath portion 50 pressed by thepressing plate 18 of theprinter unit 1, and the boundary line between some side wall portion and thebottom portion 40 where is adjacent to the portion urged thesheet 7 by ear portion, for example. - The
