The front cover 11, the plurality of calendar sheets 12, and the back cover 13 are bound by the fastener 5 in a state of being stacked in this order.

As shown in FIG. 3, each sheet 1 is a square-shaped paper. Each sheet 1 has two sides along the X1 direction and two sides along the Y1 direction. The plurality of sheets 1 have the same shape and flat area as each other. The shapes and flat areas of the plurality of sheets 1 may be different from each other. Further, in the illustrated example, the shape of each sheet 1 in a plan view is a quadrangle, but the shape of each sheet 1 in a plan view is not particularly limited. For example, it may be a triangle or a polygon of a pentagon or more. You may. Further, each sheet 1 may have curved sides in addition to the straight sides. Further, the material of the plurality of sheets 1 is paper, but the material is not limited to paper, and may be, for example, plastic.

Each of the front cover 11 and the back cover 13 is a cover that protects a plurality of calendar sheets 12. The thickness of each of the front cover 11 and the back cover 13 is thicker than the thickness of the calendar sheet 12. Therefore, deformation such as bending of the calendar sheet 12 can be suppressed. The thickness of the front cover 11 and the back cover 13 may be less than or equal to the thickness of the calendar sheet 12.

A month, a day, a day of the week, and the like are printed on the surface of the calendar sheet 12. By turning the calendar sheet 12, the calendar sheet 12 on which the target month, day, day of the week, etc. are printed can be positioned in the foreground. The number of calendar sheets 12 is not particularly limited, but is, for example, 12. However, the number of calendar sheets 12 is not limited to a plurality, and may be one.

Each sheet 1 has a plurality of through holes 15. The plurality of through holes 15 are located at the upper end of each sheet 1 and are arranged in a row in the X1 direction at equal intervals. A part of the fastener 5 is inserted into each through hole 15. In the illustrated example, the shape of each through hole 15 is rectangular, but each of these shapes is not particularly limited, and may be, for example, a circle, a triangle, or a polygon of pentagon or more. Further, the intervals between the plurality of through holes 15 are the same, but may be different. Further, although the shapes of the plurality of through holes 15 are the same as each other, they may be different from each other.

A hole 16 for inserting a hook or other hook is formed in the lower end of each sheet 1. The presence of the holes 16 allows the calendar 100 to be suspended, for example, from a wall. Further, although not shown, the hole 16 may be provided with a fastening member for binding so that the plurality of sheets 1 do not separate from each other when carried. In the illustrated example, each shape of the hole 16 is circular, but this shape is not particularly limited and may be a polygon such as a quadrangle. Further, the number of holes 16 is not limited to one, and may be a plurality. Further, the hole 16 may be omitted.

The fastener 5 is an annular member that binds each sheet 1 so that it can be rolled up. The material of the fastener 5 is not particularly limited, but is, for example, resin, metal, or paper. Further, the fastener 5 has a plurality of ring portions 51 and a regulating portion 55. The regulating portion 55 is a long portion extending in the X1 direction. The plurality of ring portions 51 and the regulation portion 55 are integrated. In the present embodiment, the thickness of the regulating portion 55 is equal to the thickness of the ring portion 51.

FIG. 4 is a developed view of the fastener 5 included in the calendar 100 shown in FIG. As shown in FIG. 4, each ring portion 51 is a portion protruding from the regulation portion 55. By forming the fastener 5 shown in FIG. 4 into an annular shape, the fastener 5 shown in FIG. 3 is obtained. As shown in FIG. 3, the ring portion 51 has a function of binding each sheet 1 so as to be rollable. The plurality of ring portions 51 are arranged at equal intervals in the X1 direction. The pitch of the plurality of ring portions 51 is equal to the pitch of the plurality of through holes 15. The plurality of ring portions 51 are arranged one-to-one with respect to the plurality of through holes 15. Each ring portion 51 is inserted through the corresponding through hole 15. The cross-sectional area of each ring portion 51 is smaller than the opening area of the through hole 15.

As described above, the regulation unit 55 is a long portion extending in the X1 direction. As shown in FIG. 2, the regulating unit 55 regulates the contact between the front cover 11 and the back cover 13 with the calendar 100 open. In particular, the regulating unit 55 regulates contact between the tip of the front cover 11 and the tip of the back cover 13. The tip of the cover 11 is the end opposite to the end on the cover 11 where the fastener 5 is located, and is the side farthest from the fastener 5. The tip of the back cover 13 is the end of the back cover 13 opposite to the end where the fastener 5 is located, and is the side farthest from the fastener 5. Further, the regulation unit 55 is common to the plurality of ring units 51. The regulating portion 55 does not insert the through hole 15. The length of the restricting portion 55 in the X1 direction is longer than the length of the through hole 15 in the X1 direction. The circumferential length of the restricting portion 55 is shorter than the circumferential length of the ring portion 51.

FIG. 5 is a side view showing a state in which the calendar 100 shown in FIG. 1 is closed. FIG. 6 is a side view showing a state in which the calendar 100 shown in FIG. 1 is opened. The calendar 100 changes from the closed state as shown in FIG. 5 to the open state as shown in FIG. 6 by turning the sheet 1. In FIGS. 5 and 6, a dot pattern is attached to the regulation unit 55 for convenience. Further, by forming the fastener 5 shown in FIG. 4 into an annular shape, the fastener 5 shown in FIG. 5 can be obtained. Therefore, as shown in FIG. 5, the tip of the ring portion 51 overlaps with the regulation portion 55.

As shown in FIG. 5, when the calendar 100 is closed, the regulating portion 55 is located between the front cover 11 and the back cover 13 in the circumferential direction of the fastener 5. Further, as shown in FIG. 6, even when the calendar 100 is open, the regulating portion 55 is located between the front cover 11 and the back cover 13 in the circumferential direction of the fastener 5.

However, as shown in FIG. 5, when the calendar 100 is closed, the regulating unit 55 is not in contact with both the front cover 11 and the back cover 13. When the calendar 100 is closed, the regulating unit 55 may be in contact with either the front cover 11 or the back cover 13. On the other hand, as shown in FIG. 6, when the calendar 100 is open, the regulating unit 55 comes into contact with both the front cover 11 and the back cover 13. Further, due to the presence of the regulating portion 55, the tip of the front cover 11 and the tip of the back cover 13 are not in contact with each other. That is, the regulating unit 55 regulates mutual contact between the tip of the front cover 11 and the tip of the back cover 13.

Therefore, by placing the back cover 13 directly on the table surface or via the calendar sheet 12 with the calendar 100 open, the front cover 11 can be made to stand up against the back cover 13. That is, the regulation unit 55 functions as an upright unit that erects the cover 11. Therefore, the calendar 100 can be used as a desk calendar. Therefore, the calendar 100 can be placed and used on a table without a bottom surface portion connecting the tip end of the front cover 11 and the tip end of the back cover 13 and a stand portion on which the calendar 100 stands, as in the conventional case. Specifically, according to the calendar 100, the calendar 100 can be used as a desk calendar simply by turning the front cover 11 and placing the back cover 13 on the table from the closed state of the calendar 100. Therefore, the time and effort required to repeatedly carry the calendar 100 and use it on the table is significantly reduced as compared with the conventional case.

Further, it is not necessary to carry the stand portion as in the conventional case. Therefore, the user of the calendar 100 can carry the calendar 100 and place the calendar 100 in various desired places for use. In addition, since it is not necessary to carry the stand portion, the troublesomeness when carrying it is greatly reduced as compared with the conventional case. Therefore, the user can use the calendar 100 not only as a desk calendar but also as a notebook. Therefore, the calendar 100 is excellent in convenience depending on the user. Further, since the fastener 5 has the regulation unit 55, the convenience of the calendar 100 is excellent and the design of the calendar 100 is excellent as compared with the case where the regulation unit 55 is a separate body from the fastener 5.

Further, as described above, when the calendar 100 is placed on a table and used, the regulation unit 55 causes the front cover 11 to stand up against the back cover 13. The angle θ between the front cover 11 and the back cover 13 may be more than 0 ° and 90 ° or less when the regulating portion 55 is in contact with both the front cover 11 and the back cover 13, but the angle θ is preferable. Is 30 ° or more and 85 ° or less, and more preferably 50 ° or more and 80 ° or less. Within such a range, the user can easily see the month, day, day of the week, etc. described on the calendar sheet 12 as compared with the case where the range is out of range.

Further, as described above, the thickness of the cover 11 is thicker than the thickness of the calendar sheet 12. Therefore, the bending of the cover 11 is suppressed as compared with the case where the thickness of the cover 11 is less than or equal to the thickness of the calendar sheet 12. Therefore, when the calendar 100 is placed on a table and used, the calendar sheet 12 is prevented from bending following the cover 11. As a result, the user can easily see the month, day, day of the week, etc. described on the calendar sheet 12. Further, the thickness of the back cover 13 is thicker than the thickness of the calendar sheet 12. Since both the front cover 11 and the back cover 13 are thick, the calendar sheet 12 is prevented from bending when the calendar 100 is carried. Therefore, the calendar 100 can be suitably used as a notebook.

Further, for example, as shown in FIG. 3, the length Lx of each sheet 1 in the X1 direction is not particularly limited, but is preferably the length Ly or more in the Y1 direction. Therefore, the length Lx of each sheet 1 is preferably 1.0 times or more the length Ly, and more preferably 1.1 times or more the length Ly. Within such a range, the bending of each sheet 1 can be suppressed when the calendar 100 is placed on the table as compared with the case where it is outside the range. As a result, it is easy to visually recognize the month, day, day of the week, etc. described on the calendar sheet 12. Therefore, the convenience of the user is further improved. The length Lx is not particularly limited, but is preferably 10 times or less the length Ly from the viewpoint of ease of printing such as the month, day, and day of the week described on the calendar sheet 12.

Further, as described above, the tip of the ring portion 51 overlaps with the regulation portion 55. Therefore, the decrease in the strength of the fastener 5 is suppressed as compared with the case where the tip of the ring portion 51 does not overlap with the regulation portion 55 and the tip of the ring portion 51 and the tip of the regulation portion 55 are in contact with each other. To. Therefore, since the tip of the ring portion 51 overlaps with the regulation portion 55, the plurality of sheets 1 can be stably bound by the fastener 5. Further, the tip of the ring portion 51 may exceed the restricting portion 55 and overlap with the base end portion of the ring portion 51, but it is preferable that the tip of the ring portion 51 does not overlap with the base end portion of the ring portion 51. That is, it is preferable that the ring portions 51 are not duplicated. If the ring portion 51 is doubled, it may be difficult for the ring portion 51 to insert the through hole 15. Further, as shown in FIG. 5, in the circumferential direction of the fastener 5, the length of the portion where the ring portion 51 of the regulating portion 55 overlaps is the length of the portion where the ring portion 51 of the regulating portion 55 does not overlap. It is preferable that it is longer than the other. As a result, the strength of the regulating portion 55 can be reinforced by a part of the ring portion 51. Therefore, the front cover 11 can be made to stand up more stably with respect to the back cover 13.

Further, in the example shown in FIG. 5, the tip of the ring portion 51 is located inside the regulating portion 55, but may be located outside the regulating portion 55. However, since the tip of the ring portion 51 is located inside the regulating portion 55, the design of the fastener 5 can be improved as compared with the case where the tip of the ring portion 51 is located outside the regulating portion 55.

As described above, since the fastener 5 has the regulation unit 55, it is possible to provide the calendar 100 which is excellent in convenience for the user. To prevent the tip of the front cover 11 and the tip of the back cover 13 from coming into contact with each other, for example, the rigidity, flat area, thickness, and material of the regulating portion 55 may be adjusted according to the material, thickness, and area of the plurality of sheets 1. It may be adjusted as appropriate.

As described above, the above calendar 100 is a combination of a general notebook and a desk calendar. The calendar 100 does not have a conventional stand that gets in the way when carried. Therefore, the calendar 100 can be closed and carried like a general notebook. Therefore, the user can fill in the schedule, etc. while looking at the calendar on the go. Further, as described above, the calendar 100 has a hole 16. Therefore, the calendar 100 can be used as a wall-mounted calendar by using the hole 16.
