Description

[Technical Field]

[0001] This invention relates to a multi-purpose desk calendar, which is an improvement over the conventional widely used desk calendar, and which greatly improves the functionality of the calendar by allowing various memo papers to be inserted and stored while the calendar is in use, or by attaching various decorative accessories to add decorativeness and thereby exerting an additional good advertising effect. [Background technology]

[0002] Desk calendars, which are generally widely used around the year-end and New Year holidays, are characterized by their folding structure, with the lunar calendar sheets for the 12 months bound by springs to both sides of a thick paper board that forms a triangular base, and up until now they have been widely used mainly as gifts by advertisers.

[0003] However, such desk calendars have the problem that their commercial value is monotonous because they do not have any special additional functions other than the lunar calendar function.

[0004] Meanwhile, as prior art for calendars with a memo paper storage function, a desk calendar equipped with a pen holder and memo paper holder, which is publicly known under Korean Utility Model Registration No. 20-0206427, and a desk calendar / memo paper holder, which is publicly known under Korean Utility Model Publication No. 20-1996-0067523, are known. However, these configurations involve a separate component, such as a pen holder or a pull-out memo paper holder, being fixedly installed in a three-dimensional manner at the bottom or side of the desk calendar. Therefore, it is economically ineffective to install such a complex memo paper holder on a desk calendar, which is widely used as a relatively inexpensive donation item. In particular, the large volume of these calendars creates distribution obstacles, such as storage and transportation, making them a structure that lacks versatility and practicality.

[0005] Most conventional desk calendars are fixed with a spring device, and are not recycled after one year of use, and most are discarded, resulting in a huge waste of resources.

[0006] In addition, desk calendars with simple bases or stands made of wood or plastic are distributed on the market, but there are limitations to the design expansion due to the weight, volume, and stability of the separate stands, and they are not suitable for promotion in corporate advertising or as gifts, so they are not widely distributed to the general public.

[0007] [Patent Document 1] Korean Registered Utility Model No. 20-0206427 [Patent Document 2] Korean Utility Model Publication No. 20-1996-0067523 Summary of the Invention [Problem to be solved by the invention]

[0008] This invention aims to provide a practical and decorative interior calendar that can be designed in an infinite number of forms by combining various characters, natural objects, animals, plants, man-made objects, and other three-dimensional or two-dimensional objects, thereby preventing the waste of resources from desk calendars that are discarded every year, and that can be reused semi-permanently by simply replacing the lunar calendar paper (internal paper).

[0009] The goal of this project is to create a desk calendar that goes beyond the design limitations of the spring calendar that has been common for the past 50 years and can be used by the masses, with new innovations.

[0010] The feature of this invention is to provide a calendar that completely renovates the simple functionality of conventional calendars, and that can form a three-dimensional holding means when the calendar is unfolded on a desk or other space for use, without compromising the original folding functionality of the calendar.

[0011] This invention installs a foldable and collapsible multi-purpose holding means of a certain width and depth on the underside or both sides of the front of a conventional desk calendar. In addition to the calendar's original function, it can also be used to attach various notepad holders or clocks, or to create an exhibition or advertising space, thereby adding a variety of functionality to the calendar. [Means for solving the problem]

[0016] Alternatively, the holding means may be characterized as including a main holder consisting of a front plate configured to support the lower front surface of the lunar calendar paper, a pair of side plates extending from both ends of the front plate and bent to cover the sides of the lunar calendar paper, a pair of divided back plates extending from each end of the side plates and bent to be connected to the back surface of the board, and connecting means formed on the back plates so that the back plates are connected to the back surface of the board.

[0017] The calendar may further include a lower panel that extends from the lower portion of the front panel, is bent, and is connected to the lower portion of the board to support the lower portion of the calendar paper.

[0018] Alternatively, the holding means may include a main holder consisting of a front plate configured to support the lower front surface of the lunar calendar paper, a pair of side plates extending from both ends of the front plate and bent to cover the sides of the lunar calendar paper, and a pair of divided rear plates extending from each end of the side plates and bent to be connected to the rear surface of the board, and may further include a reinforcing plate connected to the rear surface of the board, and an insertion groove formed between the board and the reinforcing plate so that the end of the rear plate can be inserted and connected.

[0019] Alternatively, the holding means may be characterized as including a front plate configured to support the lower front surface of the lunar calendar paper, side plates extending from one end of the front plate and bent to cover the sides of the lunar calendar paper, a back plate extending from the ends of the side plates and bent to support the back surface of the board, and connecting means formed on the back plate so that the back plate can be connected to the back surface of the board, and including a main holder that is fitted and connected at the open side to support the board and the lunar calendar paper.

[0020] Alternatively, the holding means may be characterized as including a frame-type main holder consisting of a front plate configured to support the front surface of the lunar calendar paper, a window portion configured in the front plate so that the date display on the lunar calendar paper can be seen through the front plate, side plates extending from both ends of the front plate and folded to cover the sides of the lunar calendar paper, divided back plates extending from each end of the side plates and folded to be connected to the back surface of the board, and connecting means formed on the back plate so that the back plate can be connected to the back surface of the board.

[0021] Furthermore, an insertion hole is formed in the lower part of the board, and the holding means may include a main holder consisting of a front plate configured to support the lower front part of the lunar calendar paper, and an insertion piece that protrudes from the lower part of the front plate and is configured to be fitted into the insertion hole and coupled.

[0022] Alternatively, the holding means may be characterized by including a front support piece configured to support the upper front surface of the lunar calendar paper, and a back support piece that extends from the upper end of the front support piece in a mountain shape and is bent to support the back surface of the board, and includes a sub-holder that supports the board and lunar calendar paper by their own weight.

[0023] The board may further include a support portion that protrudes forward from the lower portion of the board and is configured to support the lower portion of the lunar calendar paper.

[0024] In addition, the support portion may be characterized in that a locking protrusion or a locking groove is formed on the upper surface of the support portion to prevent the lunar calendar paper from slipping off the upper surface of the support portion. [Effects of the Invention]

[0025] Due to the structural features of the present invention, in addition to the original function of a calendar, the desk calendar of the present invention can store and keep small office items such as memo paper and writing implements in the holding means attached to the calendar itself, and various advertising displays can be effectively displayed by attaching a clock or inserting a message in the outer space of the holding means, which has industrial effects of greatly improving the functionality of desk calendars which are widely used for advertising and as gifts.

[0026] In addition, conventional calendars are fixed with a spring device, so they can only be used as a calendar and do not allow for the addition of memo paper, documents, etc. However, this invention has an open top structure, so memo paper and document paper can be inserted into the inner pages of the calendar and used, making it convenient for document work in the office.

[0027] If you make a calendar the size of A4 paper, it is convenient because you can insert A4 paper or other paper into the calendar's inner pages and use it as memo paper or notebook paper.

[0028] When the calendar base is set vertically, it can be used as a document stand, making it easy to work with PC documents and convenient for viewing various documents, flyers, brochures, etc.

[0029] By replacing the inner paper, which is the lunar calendar paper, it can be reused semi-permanently, preventing the waste of resources and helping to protect the environment.

[0030] Since spring binding is not required, the cost required for production is low.

[0031] Compared to conventional calendars, the calendar has a high degree of design flexibility and can have excellent aesthetic appeal and decorative properties, making it suitable for use as fashion interiors or works of art.

[0032] Conventional calendars are fixed on one side by a spring, making it difficult to change into various shapes. However, this invention can easily be made into a variety of shapes, such as circles, ovals, shapes of animals and plants, shapes of characters, and shapes of buildings, in addition to the common square shape of calendars, and can be designed to be aesthetically beautiful.

[0033] The holding means may be selectively attached to the front or rear of the board, or may be used by attaching it to both the front and rear surfaces simultaneously.

[0034] It is convenient because you can also put memo paper, card book, etc. into the inner pages of the calendar. With conventional desk calendars, you have to bring the entire calendar to hand when taking notes, but with this device, you only need to take out the sheet of paper you need, write notes on it, and insert it, which is convenient.

[0035] It can be used to display documents, brochures, flyers, and photographs upright.

[0036] It can be stored flat during transportation, and because it does not have spring binding and can be made thin, many calendars can be transported in a small space.

[0037] If the printing area of ​​the holding means is made large and promotional slogans are included, a high advertising effect can be expected, or if famous quotes or famous sayings are included in the holding means, it can be used as a gift or learning material.

[0038] The shape of the holding means can be variously configured, such as a horizontal straight line, or a three-dimensional representation of a natural object such as a mountain or a building such as a pyramid. The three-dimensional object can be attached and detached using a magnetic force or a snap-in method, so that it can be configured in the form of an assembly toy or a pop-up book.

[0039] A card book or a three-dimensional object can be inserted into the inner space of the holding means, or attached and detached, and can be expressed as a storytelling fairy tale or a three-dimensional object with a new aesthetic sense, and can be used as a learning and play material for brain development.

[0040] By providing a board and holding means for DIY assembly, the product can be used as an interior decoration item, a play toy, a learning aid, etc., and by further providing an image model of a three-dimensional shape, it is expected that new forms of paper art will be created.

[0041] The calendar of this invention can be made from recycled hardcover books and other materials that would otherwise be discarded, reducing waste and protecting the environment. [Brief explanation of the drawings]

[0043] The present invention aims to provide a multi-purpose desk calendar, which will be described in more detail below with reference to the accompanying drawings.

[0044] The feature of this invention is that it is manufactured with a holding means integrally attached to one or both sides of the base that makes up the base of a conventional calendar, to create a three-dimensional storage space below one side or both sides of the base. This allows the desk calendar to be well-maintained in a flat folded state during distribution. When in use, the desk calendar is erected and the holding means is assembled three-dimensionally, and the holding means with a certain width and depth is easily assembled below the calendar's monthly pages. This allows for various memo paper holders and small item display space, or advertising through the empty space outside the holding means, maximizing the advertising effect in the case of gift calendars.

[0045] FIG. 1 is a perspective view of the overall structure of a normal desk calendar (diary) 1 to which a holding means H, which is a main component of the present invention, is added and which is deployed in its normal use state.

[0046] Generally, the calendar is constructed such that a board 2 made of thick paper is erected so that a lower base 25 can serve as a base, and the base 25 is folded downward, and the lunar calendar paper 4 is placed on the front of the board 2.

[0047] The board 2 may be made of a variety of materials, such as synthetic resin, metal, wood, and the like, in addition to ordinary paper.

[0048] The board 2 can be folded on one side or stacked to stand upright and maintain a flat state, and there is no restriction on the erection assembly method.

[0049] The board 2 may have a variety of shapes, including a square, a circle, an oval, a three-dimensional object, and the like.

[0050] In the case of a spring-type calendar, after a number of holes 22 are punched in a board 2, hinge rings 23 are fitted into the holes 22 in a chain manner, and the lunar calendar paper 4 is turned from front to back once a month to be used as a calendar.

[0051] The feature of this invention is that in the general structure of a calendar, multiple lunar calendar papers 4 can be propped up against the board 2 and the lunar calendar papers 4 can be replaced or detached at regular intervals (usually once a month) without using the projection holes 22 and springs.

[0052] As shown in FIG. 1, the lunar calendar device includes a board 2 configured to stand up, one or more lunar calendar papers 4 leaned against the front of the board 2 and configured to be replaced periodically to display the date, and a holding means H configured to have a storage space S that is connected to the board 2 and into which the lunar calendar paper 4 is inserted so that the lunar calendar paper 4 does not come off the board 2.

[0053] The board 2 and the holding means H are not limited in shape and can represent a variety of things, such as animals, plants, nature, architecture, and characters.

[0054] The holding means H can be divided into a main holder 5 that supports the lower part of the lunar calendar paper by enveloping it, and a sub-holder 6 that supports the upper part of the lunar calendar paper by its own weight.

[0055] The main holder 5 has various embodiments.

[0056] As shown in Figures 2 to 7, the holding means H is characterized by including a front plate 51 configured to support the lower front part of the lunar calendar paper 4, a pair of side plates 52 extending from both ends of the front plate 51 and bent to cover the sides of the lunar calendar paper 4, and a back plate 53 extending from the ends of the side plates 52 and bent to support the back of the board 2, and including a main holder 5 in the shape of a ring with no openings on the sides that elastically supports the board 2 and the lunar calendar paper 4.

[0057] The main holder 5, the length of which is fixed as described above, is preferably made of a soft material rather than a hard material to have elasticity, or to have an iron core or the like built in.

[0058] The board 2 can be configured in various forms as shown in FIG. 3, and the holding means H can be applied to the board 2 in various forms for high versatility.

[0059] In the embodiment, it is assumed that the support part 3 protrudes forward from the lower part of the board 2 as a basic configuration, but there are also embodiments in which the support part 3 is not provided, as will be explained later.

[0060] As shown in Figures 2 to 5, the space W between the side panels 52 of the main holder 5 may be formed to a size w1 that allows the lunar calendar paper 4 to be appropriately supported, or as shown in Figures 6 and 7, the space W between the side panels 52 of the main holder 5 may be formed to a size w2 that allows the lunar calendar paper 4 to be stored along with additional personal belongings (e.g., memo paper, etc.).

[0061] In another embodiment, as shown in FIG. 8, the holding means H can be characterized as including a main holder 5 consisting of a front plate 51 configured to support the lower front part of the lunar calendar paper 4, a pair of side plates 52 extending from both ends of the front plate 51 and bent to cover the sides of the lunar calendar paper 4, a back plate 53 extending from the ends of the side plates 52 and bent to support the back of the board 2, and a connecting means 54 configured at the divided ends of the front plate 51, side plate 52, or back plate 53, which is separated so that the divided ends can be detached from each other.

[0062] Therefore, the length of the main holder 5 can be adjusted depending on the positions at which the connecting means 54 are connected to each other.

[0063] Furthermore, the side panel 52 may further include a plurality of variable folding lines 55 formed thereon so that the length of the side panel 52 can be changed.

[0064] The variable folding lines 55 indicate positions at which the user can fold the side panel 52, and the user can select any of the variable folding lines 55 to fold the side panel 52.

[0065] Depending on the folding of the side panels 52, variable fold lines 55 may also be located on the front panel 51 or the back panel 53.

[0066] The variable folding line 55 can be represented in the form of a scaled ruler, and the scale indicating the folding portion can be standardized to adjust the size of the main holder 5, and an iron core material can be inserted inside the main holder 5 to reinforce its strength.

[0067] The holding means H is made of a metal material so as to be bendable, or a metal thread or metal plate is inserted into the holding means H.

[0068] In the above-described embodiment, the main holder 5 is not directly attached to the board 2 but is wrapped around it separately, allowing the main holder 5 to move in the vertical direction of the board 2. In contrast, in the following embodiment, the main holder 5 is directly attached to the board 2, providing a stronger attachment force.

[0069] In another embodiment, as shown in Figures 9(a) to 10, the holding means H can be characterized as including a main holder 5 consisting of a front plate 51 configured to support the lower front side of the lunar calendar paper 4, a pair of side plates 52 extending from both ends of the front plate 51 and bent to cover the sides of the lunar calendar paper 4, a pair of divided back plates 53 extending from each end of the side plates 52 and bent to be connected to the back side of the board 2, and a connecting means 54 formed on the back plate 53 so that the back plate 53 can be connected to the back side of the board 2.

[0070] Alternatively, as shown in FIG. 9(b), the main holder 5 may be configured such that the front panel 51 is divided into a pair, the rear panel 53 is integrally connected to the front panel 51, and the rear panel 53 is formed with a connecting means 54 so that the rear panel 53 can be connected to the rear of the board 2.

[0071] The connecting means 54 may be any of hook buttons, Velcro (registered trademark) tape (surface fastener), double-sided adhesive tape, magnets (ferrite permanent magnets), and the like.

[0072] In a further embodiment, a watch T may be attached to the holding means H, as shown in FIG.

[0073] The clock T may be attached to the holding means H or may be configured to be inserted into the holding means H, regardless of whether it is a digital clock or an analog clock.

[0074] If the clock T is provided in the holding means H, the added value of the desk calendar 1 can be increased, and it can be made more luxurious, and it is convenient because the calendar and the clock can be checked at the same time.

[0075] In another embodiment, as shown in Figures 11 to 17, the calendar may further include a lower panel 56 that extends from the lower part of the front panel 51, is bent, and is connected to the lower part of the board 2, and is configured to support the lower part of the lunar calendar paper 4.

[0076] The main holder 5 is the part that is placed horizontally below the lunar calendar paper 4 and is shown on the front, and side panels 52 and a back panel 53 are installed on both sides of the main holder 5 so that they can be folded along fold lines, and the back panel 53 is folded in a bent state toward the back side of the board 2 and fixed to the inside of the board 2 by a connecting means 54.

[0077] When used in the desk calendar 1, the back panel 53 is folded along the folding lines and fixed to the back side of the board 2 in a bent state.

[0078] In addition, a lower plate 56 is defined below the main holder 5 to maintain a space with a width having a spacing W like the side plate 52, and again, an attachment means 56a is formed in the longitudinal direction below the lower plate 56 so that the attachment means 56a of the main holder 5 is fixed and attached to the underside of the board 2.

[0079] The attachment position of the attachment means 56a is such that when the calendar 1 is set upright with the receiving plate 3 of the board 2 as a boundary as shown in Figures 14 to 16, it is not visible on the front surface of the main holder 5 but is attached and fixed three-dimensionally so as to be located below the receiving plate 3.

[0080] When the attachment means 56a is attached and fixed to the lower board 2 of the desk calendar 1 as described above, the main holder 5 becomes one with the desk calendar 1, and during distribution, the side panels 52 and back panel 53 can be folded in the front-to-back direction as shown in Figure 17 to maintain a flat state, thereby making the volume thinner and simpler for transportation and storage.

[0081] When the desk calendar 1 is placed on a desk or the like for use, the base 25 below the board 2 is unfolded into a triangular shape to stand it on the desk, and then the main holder 5 forms a storage space S so that the lower plate 56 and the side plates 52 on both sides can maintain a certain space.

[0082] At this time, the rear panel 53 is fixed to the rear of the board 2 by suitable connecting means 54, and a storage space S consisting of only the space W between the side panel 52 and the bottom panel 56 is formed.

[0083] In this way, when the storage space S is formed by the main holder 5 below the calendar 1, various kinds of memo paper, writing implements, necessary stationery, picture and photo frames, etc. can be inserted into the storage space S and used for convenient storage of small items.

[0084] Therefore, there is no need to use a separate memo paper holder or small item storage box, and in particular, various promotional means such as advertising copy, pictures, photos, and catchphrases can be displayed on the front of the main holder 5, which can greatly emphasize and improve the advertising function of the calendar, which is mainly provided as a promotional means for companies, exhibition planning companies, restaurants, financial service companies, etc., and has the advantage of greatly improving the functionality that existing calendars have not had until now.

[0085] Meanwhile, when a solid panel having a certain thickness is used for the main holder 5, it can be made into a three-dimensional shape as shown in FIG. 1 or 13 in addition to a linear shape, thereby further enhancing the advertising effect and decorativeness. It is also possible to separately attach additional decorations such as an electronic clock, a thermo-hygrometer, various character models, etc. to one side of the main holder 5.

[0086] Basically, the monthly calendar paper 4 is inserted into the storage space S in card format and replaced one sheet per month, but it can also be applied to a desk calendar 1 with a hinge ring 23 as shown in Figures 12 and 13.

[0087] In another embodiment, as shown in FIG. 3(c) and FIG. 18, the holding means H may include a main holder 5 consisting of a front plate 51 configured to support the lower front part of the lunar calendar paper 4, a pair of side plates 52 extending from both ends of the front plate 51 and bent to cover the sides of the lunar calendar paper 4, and a pair of divided rear plates 53 extending from each end of the side plates 52 and bent to be connected to the rear surface of the board 2, and may further include a reinforcing plate 21 connected to the rear surface of the board 2, and an insertion groove 21a formed between the board 2 and the reinforcing plate 21 so that the end of the rear plate 53 can be inserted and connected.

[0088] Therefore, since it is a detachable system without attachment, the main holder can be easily replaced, and when an expired advertisement slogan is written on the main holder, it can be easily replaced.

[0089] In another embodiment, as shown in FIG. 19, the holding means H may be characterized as including a front plate 51 configured to support the lower front side of the lunar calendar paper 4, a side plate 52 extending from one end of the front plate 51 and bent to cover the side of the lunar calendar paper 4, a back plate 53 extending from the end of the side plate 52 and bent to support the back side of the board 2, and a connecting means 54 formed on the back plate 53 so that the back plate 53 can be connected to the back side of the board 2, and including a main holder 5 that is fitted and connected at the open side to support the board 2 and the lunar calendar paper 4.

[0090] Since the support force may be weakened by joining the main holders at the side, a plurality of main holders 5 may be provided as in the embodiment shown in the drawings.

[0091] In yet another embodiment, as shown in Figures 20 and 21, the holding means H can be characterized as including a frame-shaped main holder 5 consisting of a front plate 51 configured to support the front side of the lunar calendar paper 4, a window portion 51a configured in the front plate 51 so that the date display of the lunar calendar paper 4 can be seen through the front plate 51, side plates 52 extending from both ends of the front plate 51 and bent to cover the sides of the lunar calendar paper 4, a back plate 53 extending from each end of the side plate 52 and bent to be connected to the back side of the board 2, and connecting means 54 formed on the back plate 53 so that the back plate 53 can be connected to the back side of the board 2.

[0092] When configured as described above, the calendar frame can be decorated like a picture frame, and a photograph can be inserted in place of the lunar calendar paper 4 to use it as a picture frame.

[0093] As shown in Figure 22, while the front of the lunar calendar paper 4 is supported by a frame-type holding means H, it is also possible to provide a connecting means 54 such as a metal plate on the front panel 51, which has a window portion 51a formed in the front panel 51 so that the date display on the lunar calendar paper 4 can be seen through the front panel 51, and to provide a connecting means 54 such as a magnet at a corresponding position on the board 2 so that it can be attached and detached by magnetic force.

[0094] In another embodiment, as shown in FIG. 23, an insertion hole 24 is further formed in the lower part of the board 2, and the holding means H includes a main holder 5 consisting of a front plate 51 configured to support the lower front part of the lunar calendar paper 4, and an insertion piece 57 protruding from the lower part of the front plate 51 and configured to be fitted into the insertion hole 24 and coupled thereto.

[0095] The above configuration can further include anti-detachment steps 57a that protrude from both ends of the insertion piece 57 and prevent the insertion piece 57 from detaching, thereby preventing the coupled insertion piece 57 from detaching from the insertion hole 24.

[0096] In this embodiment, the side plate 52 and the rear plate 53 are not shown in the drawings, but it is obvious that the side plate 52 and the rear plate 53 can be further added.

[0097] In another embodiment, the holding means H may be characterized as including a sub-holder 6 that comprises a front support piece 61 configured to support the upper front surface of the lunar calendar paper 4, and a back support piece 62 that extends from the upper end of the front support piece 61 in a mountain shape and is bent to support the back surface of the board 2, as shown in Figure 1 or Figure 24, and that supports the board 2 and lunar calendar paper 4 by their own weight.

[0098] In this case, the lunar calendar paper is thin and can be prevented from folding forward or being wound up.

[0099] Although not shown in the figure, by combining the sub-holder 6 with the frame-type holding means H shown in Figure 21, it is also possible to construct a sub-holder 6 in which a front support piece 61 and a rear support piece 62 are connected to the top of a front panel 51 having a window portion 51a.

[0100] Furthermore, the board 2 may further include a support portion 3 that protrudes forward from the lower portion thereof and is configured to support the lower portion of the lunar calendar paper 4.

[0102] The locking protrusion 31 or the locking groove 32 can be configured to be detachable from the support part 3 using a magnet or a fitting method.

[0103] In the modified embodiment, as shown in FIG. 3(d), a raised portion 33 can be further formed at the front end of the support portion 3 of the board so that the support portion 3 of the board has a downward inward slope. When formed in this manner, it is possible to guide the lunar calendar paper 4 so that it adheres closely to the board 2.

[0104] As another point, one embodiment of a method for erecting the board 2 is shown in Figure 27, where the unfolded view as shown in (b) is folded along the fold line, and the assembly mounting portion formed on one side of the front panel 21 is attached to the board 2, thereby erecting the board 2.

[0105] This invention is a very useful invention that dramatically improves the advertising function and convenience of the calendar by adding a main holder 5 to a desk calendar (diary) 1, which has a conventional simple structure, so that it can be used both as a calendar and as a pocket for storing small items such as memo paper and writing utensils.

[0106] Although the detailed description of the present invention has been given above with reference to the most preferred embodiment of the present invention, various modifications are possible within the scope of the technical scope of the present invention. Therefore, the scope of protection of the present invention is not limited to the above embodiment, but should be recognized to include the technology of the claims below and technical means equivalent to these technologies. [Industrial Applicability]

[0107] This invention prevents the waste of resources that comes with discarding desk calendars every year, and can be reused semi-permanently by simply replacing the monthly calendar paper (internal paper). The calendar is equipped with a holding means at the bottom, which means that in addition to its original function as a calendar, it can also be used as various memo paper or advertising space, making it highly versatile and highly industrially applicable.
