[0009] Below, preferred embodiments of the pen holder structure 10 of the present invention, the cover structure 20 to which the pen holder structure 10 is connected, and the booklet structure 100 in which a sheet-like member (refill) is attached to the cover structure 20 are described in detail with reference to the drawings. Note that the embodiments described below are preferred specific examples of the present invention, and therefore various technically preferable limitations are attached, but the scope of the present invention is not limited to these embodiments unless otherwise stated in the following description to the effect that the present invention is particularly limited.

[0010] Embodiment 1 1. Overall structure of booklet structure 100 Fig. 1 is a perspective view of a booklet structure 100 according to the first embodiment in a closed state. Fig. 2 is a perspective view of the booklet structure 100 according to the first embodiment in an open state, with the pen holder structure 10 open. Fig. 3 is a front view and a bottom view of the booklet structure 100 shown in Fig. 2. The booklet structure 100 is configured to include a cover structure 20, a plurality of sheet-like members 30 (hereinafter also referred to as refills 30) held by the cover structure 20, and a pen holder structure 10 connected to the cover structure 20.

[0011] As shown in Figures 1 to 3, the cover structure 20 has a spine portion 21 and a cover portion 22 provided contiguous therewith, and is configured to be able to hold the refill 30 in a bound state. A plurality of ring-shaped binding devices 23 are attached to the spine portion 21, and the sheet-like refill 30 is detachably bound by these rings 23. The cover portion 22 is configured to cover the top and bottom surfaces of the refill 30 (covering it from the z direction) when the booklet structure 100 is closed, and the cover structure 20 as a whole forms a portable notebook-like form that protects the refill 30.

[0012] The pen holder structure 10 is connected to a binding device 23 (ring 23) provided on the cover structure 20, and includes a connecting portion 11, a pen holder portion 12, and a clamped portion 13. As shown in FIG. 1, the pen holder structure 10 forms a cylindrical space S that holds a writing implement 90 arranged along the outer periphery of the refill 30. The connecting portion 11 is connected to a predetermined position on the cover structure 20 via a connecting structure 15, and the pen holder structure 10 can also be configured to be easily attached and replaced.

[0013] As shown in Figure 1, when the booklet structure 100 is closed, the clamped portion 13 is clamped between the refills 30 or between the refills 30 and the cover portion 22, thereby stabilizing the position of the tip side of the pen holder structure 10 (the left end of the pen holder structure 10 in Figure 3) and maintaining the cylindrical space S that holds the writing instrument 90.

[0014] The Cartesian coordinate system (x, y, z) shown in each figure is defined for the sake of convenience in explaining the structure of booklet structure 100. The x direction indicates the opening and closing direction of booklet structure 100 (the opening direction of cover portion 22), the y direction indicates the binding direction of refill 30 (the arrangement direction of rings 23), and the z direction indicates the thickness direction (the direction in which refill 30 is sandwiched between cover portion 22 and spine portion 21).

[0015] In the embodiments, the term "booklet structure 100" refers to the entire configuration including the cover structure 20 and the sheet-like member 30 (refill 30) held by the cover structure 20. In addition, in the description of the embodiments, the term "cover structure 20" refers to the entire configuration including the spine portion 21, the cover portion 22, and the ring-shaped binding device 23 attached thereto. On the other hand, the term "cover structure 20" may also encompass a state in which the penholder structure 10 is connected. In other words, the cover structure 20 is not limited to a simple cover body with a binding device, but may also include a configuration in which the penholder structure 10 is integrally provided. In addition, the booklet structure 100 can be configured to hold a booklet instead of a refill, and such a modification will be described later.

[0016] 2. Structure of the cover structure 20 1 to 3, cover structure 20 includes spine portion 21, cover portion 22, and ring-shaped binding device 23, and is configured to be able to hold refill 30. Cover structure 20 forms the framework of booklet structure 100, and functions as the base of the entire structure including pen holder structure 10.

[0017] The spine portion 21 is a portion that serves as a reference for opening and closing the cover portion 22 of the cover structure 20, and as can be seen in Figure 3(b), a binding device 23 is installed on the surface (inner surface) on the z-direction side together with a base member 25. As shown in Figures 2 and 3, the binding device 23 has a ring-like shape, and binds the sheet-like member 30 (refill) with an openable and closable mechanism, similar to a so-called ring binder. This makes it possible to attach, detach, and replace the refill 30.

[0018] The cover portion 22 is connected to the spine portion 21 and extends from the spine portion 21 in both the positive and negative x-directions (both right and left directions in FIG. 3) when the booklet structure 100 shown in FIG. 3 is open. In the first embodiment, the cover portion 22 is detachably connected to the spine portion 21 via a connecting member 24, but the cover portion 22 and the spine portion 21 may be formed as a continuous, integrated unit. As shown in FIG. 1, the cover portion 22 is arranged to cover the top surface of the refill 30 when the booklet structure 100 is closed. The cover portion 22 is configured to be openable and closable during use, allowing the booklet structure 100 to be opened and used like a notebook or a planner. As shown in FIG. 3(b), the cover portion 22 is thin in the z-direction and serves to protect the refill 30, the pen holder structure 10, etc. while reducing the thickness when stored.

[0019] As shown in Fig. 3(b), the binding device 23 is held in a predetermined position by the spine portion 21 via a base member 25. The base member 25 fixes the binding device 23 to the spine portion 21 and has a structure for opening and closing the binding device 23. Note that the binding device 23 is not limited to a ring-shaped structure, and other structures can be adopted as long as it can hold the refill 30.

[0020] When the booklet structure 100 is closed, the cover portion 22 is arranged to cover the clamped portion 13 of the penholder structure 10. At this time, the clamped portion 13 is clamped between the refill 30 and the cover portion 22 or between the refills 30, and the end of the penholder structure 10 is held inside the booklet structure 100 (see, for example, FIG. 7).

[0021] 3. Pen holder structure 10 3.1. Structure of the pen holder structure 10 4A to 4C are a front view (FIG. 4A), a bottom view (FIG. 4B), and a rear view (FIG. 4C) of the pen holder structure 10 according to embodiment 1. As also shown in FIGS. 1 to 3, the pen holder structure 10 is configured to be attached to the cover structure 20, and is arranged in a state where it is stacked in the surface direction of the staple-refill 30 housed inside the booklet structure 100.

[0022] As shown in Fig. 4, pen holder structure 10 is configured to include connecting portion 11, pen holder portion 12, and clamped portion 13. Connecting portion 11, pen holder portion 12, and clamped portion 13 are arranged side by side in the x direction, with pen holder portion 12 connected to the end of connecting portion 11 on the negative side in the x direction, and clamped portion 13 connected to the end of pen holder portion 12 on the negative side in the x direction. In other words, pen holder structure 10 is a substantially sheet-shaped member extending from connecting structure 15 in the opposite direction to the x direction (negative direction), and is configured such that connecting portion 11, pen holder portion 12, and clamped portion 13 are connected side by side in this order. The direction in which pen holder structure 10 extends is sometimes referred to as the "first direction."

[0023] The connecting portion 11 is a portion that is connected to the ring-shaped binding device 23, and a connecting structure 15 is provided at its end on the positive side in the x direction. The end of the connecting portion 11 where the connecting structure 15 is provided is referred to as the first end 11a. The connecting structure 15 is connected by the binding device 23 of the cover structure 20. The connecting structure 15 is, for example, a plurality of holes, and is connected by passing it through the ring 23 on the cover structure 20 side.

[0024] The penholder portion 12 is connected to the negative end of the connecting portion 11 in the x-direction, and as shown in Figures 4(a) and 4(c), the penholder structure 10 is formed as a strip-shaped member extending along the x-direction. The end of the connecting portion 11 to which the penholder portion 12 is connected is referred to as the second end 11b. The penholder portion 12 has a recess 12a formed in its central portion in the x-direction, and by bending mainly the portion where this recess 12a is provided, a cylindrical space S (see Figure 1) can be formed between the penholder portion 12 and the outer periphery of the sheet-like member 30.

[0025] The clamped portion 13 is connected to the tip of the pen holder portion 12 on the negative side in the x direction. As shown in Fig. 4(b), the clamped portion 13 is configured in a thin, flat shape. When in use, the clamped portion 13 is sandwiched between the refills 30 or between the refill 30 and the cover portion 22, thereby stably supporting the tip side of the pen holder structure 10 (the tip side as the part to which the connecting structure 15 is fixed).

[0026] As shown in FIG. 4(c), a connection portion 17 between the connecting portion 11 and the pen holder portion 12, and a connection portion 16 between the pen holder portion 12 and the clamped portion 13 are formed, and the respective components are integrally connected. These connection portions 16, 17 can be realized by bonding, sewing, integral molding, or the like. In the first embodiment, the connecting portion 11, the pen holder portion 12, and the clamped portion 13 are each separately manufactured components, and the pen holder structure 10 is formed by joining them together. Below, the connecting portion 11, the pen holder portion 12, and the clamped portion 13 will each be described.

[0027] 3.1.1. About the connecting part 11 In the pen holder structure 10 according to the first embodiment, the connecting portion 11 is a portion that is connected to the cover structure 20 and is a base portion for fixing the pen holder structure 10 inside the booklet structure 100.

[0028] As shown in Figure 4, the connecting portion 11 is composed of a plate-like member formed by stacking multiple leather sheets. The leather sheets are integrated by sewing or gluing, and may contain a resin core member inside as needed. This configuration ensures appropriate flexibility and workability, while also making the structure less likely to break when attached to the binding device 23. It is also possible to use materials such as cloth or synthetic resin as an alternative to the leather sheets.

[0029] A connecting structure 15 is provided at the end of the connecting portion 11, and in the first embodiment, is configured as a plurality of holes through which the ring-shaped binding device 23 is passed. The connecting structure 15 is provided at the end of the connecting portion 11 in the direction in which the pen holder structure 10 extends (the first direction opposite to the x direction in FIG. 4). Note that the configuration of the connecting structure 15 is not limited to this, and it is also possible to adopt an insertion structure using a tab member, a hook-and-loop fastener, a magnet, a button, or other configuration, as will be described later in a modified example. In other words, there are no particular limitations on the configuration of the connecting structure 15, as long as it can detachably connect the pen holder structure 10 to the cover structure 20.

[0030] Furthermore, the shape of connecting portion 11 is generally plate-like, and is set to a size equal to or smaller than that of sheet-like member 30 (refill 30) held in booklet structure 100. In particular, connecting portion 11 is sized so that it does not protrude from cover structure 20 when in use and does not adversely affect the appearance of booklet structure 100 when stored. The thickness of connecting portion 11 can be set arbitrarily as long as it has a degree of rigidity that allows stable attachment to binding device 23.

[0031] Furthermore, as shown in FIG. 4, a holding member 14 is provided on the surface of the connecting portion 11. The holding member 14 is fixed to the surface of the connecting portion 11 via a fixing portion 14b, and its tip 14a is formed as a free end. The tip of the clamped portion 13 is inserted between the holding member 14 and the connecting portion 11, thereby enabling the pen holder structure 10 to maintain its folded state. This configuration makes it easy to maintain its shape when stored and prevents it from coming off or deforming when carried. In FIG. 4, the fixing portion 14b is formed by, for example, attaching a semicircular leather sheet to a plate-shaped member by sewing, but it may also be attached by other means such as adhesive.

[0032] 3.1.2. Pen holder part 12 The pen holder portion 12 in the pen holder structure 10 is a member that forms a storage section capable of holding a writing instrument P, and is formed to be approximately cylindrical or semi-cylindrical when the pen holder structure 10 is closed, as shown in Figure 4.

[0033] In the first embodiment, the pen holder portion 12 is made of a leather sheet, which has a moderate flexibility and frictional resistance, and is therefore able to stably hold writing implements P of various thicknesses. The leather sheet that constitutes the pen holder portion 12 may be processed into a semi-cylindrical shape, and its ends are connected to the connecting portion 11 and the clamped portion 13 by means of sewing, adhesive, or the like.

[0034] One end (base end) of pen holder portion 12 is sandwiched between the multiple leather sheets of connecting portion 11 and is sewn together with them, thereby being firmly connected to connecting portion 11. In this way, pen holder portion 12 is formed integrally with connecting portion 11, and does not come off during use, providing stable holding power.

[0035] Furthermore, the edge of the pen holder portion 12 in the y direction does not have to have a shape with recesses 12a as shown in Fig. 4, and may be linear or have another shape. As an example of the structure of the pen holder portion 12, it is also possible to provide an anti-slip material or a member that reduces insertion resistance on the inner surface (the surface on the side shown in Fig. 4(c)).

[0036] The material of the pen holder portion 12 is not limited to leather, but may be synthetic resin, cloth, or a composite material thereof.

[0037] 3.1.3. Regarding the clamped portion 13 The clamped portion 13 is provided at the tip side of the pen holder structure 10 and is a member that plays a role in stably supporting the cylindrical space S of the pen holder structure 10 by being clamped between the sheet-like member 30 (refill 30) held within the cover structure 20, or between the cover portion 22 and the sheet-like member 30.

[0038] As an example, the sandwiched portion 13 is made of a transparent sheet made of polyvinyl chloride (PVC). PVC sheets have a high degree of recovery when bent compared to leather sheets and the like, and have the property of easily returning to their original shape when bent. Furthermore, because they are thin yet have a certain degree of hardness (for example, rigidity sufficient for use as a pad), they can be stably sandwiched between the sheet-like member 30 and the cover structure 20.

[0039] With this configuration, the clamped portion 13 is stably held without easily deforming when clamped in the refill 30, and can maintain the shape of the pen holder portion 12. Furthermore, because the clamped portion 13 is transparent, it does not interfere with the visibility of the written contents on the refill 30, and does not impair convenience for the user.

[0040] Furthermore, since the clamped portion 13 is made of a polyvinyl chloride (PVC) sheet, it also functions as a writing pad when in use, and by placing it under the writing surface, it has the effect of improving writing performance. Therefore, the clamped portion 13 is sandwiched between the sheet-like member 30 and the like, and not only holds the pen holder portion 12 in a cylindrical shape, but also can be used as an auxiliary member to improve the work efficiency of the user.

[0041] The material of the clamped portion 13 is not limited to the above, and various materials can be used, such as resin, metal, wood, etc. However, it is desirable that the clamped portion 13 be made of a material that is at least more resilient than the material that constitutes the pen holder portion 12. It is also desirable that the surface be flat.

[0042] The x-direction dimension of the clamped portion 13 is set to be longer than the x-direction dimension of the pen holder portion 12, and is configured so that it is stably clamped between the refills 30 even when the booklet structure 100 is closed. In addition, the clamped portion 13 is set to appropriate dimensions in both the width direction and length direction so that it does not protrude from the booklet structure 100. The x-direction dimension of the clamped portion 13 is preferably set to be the same as or slightly larger than the x-direction dimension of the writing surface of the refill 30 (the dimension from the connecting hole of the refill 30 to the outer periphery).

[0043] As described above, the pen holder structure 10 has the connecting portion 11 attached to the ring 23 and the clamped portion 13 clamped inside the refill 30, which allows the pen holder portion 12 to bend and stably form a cylindrical space S capable of accommodating the writing instrument 90.

[0044] 3.2. Function of the pen holder structure 10 FIG. 5 is a perspective view showing the pen holder structure 10 in an open state and a closed state when the booklet structure 100 according to the first embodiment is in an open state. FIG. 6 is a front view and a bottom view of the booklet structure 100 shown in FIG. 5. As shown in FIGS. 5 and 6, when the booklet structure 100 is in an open state ((a) of FIGS. 5 and 6), the clamped portion 13 of the pen holder structure 10 is free and separated from the refill 30 and the cover portion 22, and the pen holder portion 12 is laid out flat along the x direction. From this state, as shown in (b) of FIGS. 5 and 6, by closing the clamped portion 13 of the pen holder structure 10 and closing the cover portion 22, the clamped portion 13 transitions to a state where it is clamped between the refill 30 and the cover portion 22.

[0045] 5 and 6(b) to the completely closed state of the booklet structure 100, i.e., the state shown in FIG. 1, the clamped portion 13 is securely clamped between the refill 30 and the cover portion 22. The portion between the two recesses 12a provided at both ends of the center of the pen holder portion 12 in the y direction bends in the x direction, forming a cylindrical space S for accommodating a pen (writing implement 90). The tip side of the pen holder structure 10 is fixed by being clamped between the refill 30 and the like, making it possible to stably maintain the cylindrical space S. Furthermore, since the clamped portion 13 can move in the x direction while being clamped between the refill 30 and the like, the size of the cylindrical space S formed by the pen holder portion 12 can be adjusted by adjusting its position in the x direction. In other words, moving the clamped portion 13 in the direction of pulling it out of the refill 30 enlarges the cylindrical space S, and moving the clamped portion 13 toward the rear reduces the cylindrical space S. This allows the cylindrical space S to accommodate a wide range of writing implements 90, from thin to thick, and also makes it possible to accommodate a plurality of writing implements 90.

[0046] Furthermore, the pen holder structure 10 can easily switch between a state in which the cylindrical space S is formed and a state in which it is not formed when the booklet structure 100 is in an open state. In the open state, the pen holder portion 12 unfolds, making it easy to insert and remove pens and replace the holder itself, and in the closed state, the clamped portion 13 is clamped, allowing for stable pen holding. Note that the pen can be inserted and removed from the pen holder portion 12 even when it is in the closed state.

[0047] Furthermore, the portion of the pen holder portion 12 where the recess 12a is provided is more flexible than the surrounding area, so that the cylindrical space S can be reliably formed with the flexibility required for inserting and removing a pen, despite the simple structure. This structure allows the user to easily attach the pen holder structure 10 to a notebook, binder, etc., and to reliably hold a pen.

[0048] 3.3. Dimensioning of the pen holder structure 10 Figure 7 is a bottom view of booklet structure 100 according to embodiment 1. Figure 7(a) corresponds to a bottom view of booklet structure 100 shown in Figure 1 in a closed state, and shows a normal storage state in which writing implement 90 is inserted into pen holder structure 10. Figure 7(b) shows a state in which clamped portion 13 has been pulled out to the maximum extent in the x direction from the state shown in Figure 7(a). Figure 7(c) is a diagram schematically showing the structure of booklet structure 100 as seen from the bottom, and is intended to visually explain the relationship between the dimensions of each part of pen holder structure 10.

[0049] As shown in FIG. 7(b), the pen holder structure 10 is desirably configured so that the clamped portion 13 does not fall out as much as possible when the booklet structure 100 is closed. Therefore, it is preferable that the tip 13a of the clamped portion 13 remains between the sheet-like members 30 (refill 30) even when the clamped portion 13 is pulled out from between the sheet-like members 30. For example, in FIG. 7(c), if the tip 13a is at position "p" (around the center of the refill 30 in the x direction) or position "q," the clamped portion 13 is unlikely to fall out if the cover 22 is closed. However, if the tip 13a is at position "r" (around the tip 22a of the cover 22), the tip 13a of the clamped portion 13 will not fall out if the cover 22 is completely closed, but there is a possibility that the tip 13a of the clamped portion 13 will fall out if the cover 22 is slightly opened.

[0050] To satisfy the condition that prevents the clamped portion 13 from slipping out from between the refills when the cover portion 22 is closed, we consider the condition shown in FIG. 7(c), where the surfaces of the clamped portion 13 and the connecting portion 11 are adjacent to each other, i.e., the most unfavorable condition for pulling out the clamped portion 13. In this condition, the x-direction length L3 of the clamped portion 13 needs to be set to be at least longer than the x-direction length L2 of the pen holder portion 12. In other words, the pen holder structure 10 is set so that L3 > L2. Note that this condition is based on the premise that the x-direction length of the connecting portion 11 is at least equal to or greater than the x-direction length of the refill 30.

[0051] Preferably, the position of the tip 13a of the sandwiched portion 13 is desirably at the central portion from the binding portion 30b to the tip 30a of the refill 30 in a state where the pen holder portion 12 is extended maximally in the x direction (the state of "p" in FIG. 7). Thereby, the sandwiched portion 13 is stably held between the refills 30, and the risk of falling out during the opening / closing operation or carrying can be reduced. The x-direction length L1 from the connecting structure 15 of the connecting portion 11 to the tip on the second end portion 11b side is set to be equal to or greater than the x-direction length from the binding portion 30b to the tip 30a of the sheet-like member 30 (refill 30) held by the booklet structure 100. Also, the position of the tip on the second end portion 11b side of the connecting portion 11 is set so as not to protrude from the tip 22a of the normal cover portion 22. At this time, when the length from the connecting structure 15 of the connecting portion 11 to the tip on the second end portion 11b side is L1, a relationship of L1 + L2 - L3 < L1 / 2 is desirable. Thereby, the sandwiched portion 13 is not easily pulled out in a state where the booklet structure 100 is closed.

[0052] Furthermore, it is desirable that the x-direction dimension of the sandwiched portion 13 is configured so as not to protrude from the booklet structure 100 when sandwiched by the refill �0. Therefore, it is desirable that the x-direction length L3 of the sandwiched portion 13 is set so as not to protrude from the tip 22a of the cover portion 22 in a state where the sandwiched portion 13 is inserted to the deepest. Also from this viewpoint, it is preferable that the x-direction length L3 of the sandwiched portion 13 satisfies at least the relationship L1≧L3. Since a longer x-direction dimension of the sandwiched portion 13 is advantageous for pulling out, it is desirable that it is about the same as or slightly larger than the x-direction length from the binding portion 30b to the tip of the refill 30. That is, it is particularly desirable that the pen holder structure 10 is set such that the x-direction length is L1≒L3. Thereby, the sandwiched portion 13 can be stored between the refills 30 without interfering with the fastener 23 of the cover structure 20 in a state of being inserted to the deepest of the booklet structure 100, and is configured not to protrude from the booklet structure 100, and the balance of the overall structure is also kept good.

[0053] When the clamped portion 13 is used as a writing pad, it is particularly desirable to set the x-direction dimension of the clamped portion 13 so that L1 ≒ L3. By configuring the penholder structure 10 in this manner, the clamped portion 13 can cover the writing area of ​​the sheet-like member 30, and is unlikely to come off when carried, making it a functional and easy-to-use member.

[0054] 4. Variations 4.1. Modification 1 of the pen holder structure 10 8A, 8B, and 8C are diagrams showing a first modified example of the pen holder structure 10 according to the first embodiment, with Fig. 8A being a front view, Fig. 8B being a bottom view, and Fig. 8C being a rear view. This modified example differs from the example shown in Fig. 4 in that the connecting portion 11 and the pen holder portion 12 are integrally configured.

[0055] That is, in the example of Figure 4, the pen holder structure 10 is constructed by joining different parts at the connection part 17 between the connecting part 11 and the pen holder part 12, but in variant example 1 shown in Figure 8, these are constructed from a single part made of the same material, which makes it possible to reduce the number of parts and simplify the manufacturing process.

[0056] The pen holder structure 10 according to the first modification also has a modified configuration of the holding member 14 provided on the connecting portion 11. In the example of Fig. 4, the connecting portion 11 is configured by joining a separate semicircular member (holding member 14) to the surface thereof, but in Fig. 8, an arc-shaped slit is provided in the base material of the connecting portion 11 itself, and part of this slit is cut out to form the holding member 14.

[0057] In this way, the pen holder structure 10 has a structure in which a portion is cut and raised by the slit, eliminating the need for processes such as gluing or welding separate members, which contributes to simplifying the structure and reducing costs. Also, because the holding member 14 is configured as part of the connecting portion 11, it has a sense of unity in terms of strength, which also has the effect of reducing the risk of breakage.

[0058] Furthermore, in the first modification, a recess 12a is formed in the center of the pen holder portion 12, and similar to the action shown in Fig. 7, when the booklet structure 100 is closed, the portion of the pen holder portion 12 where the recess 12a is formed and its surrounding area bend, thereby forming a cylindrical space S for holding the writing implement 90. Note that the recess 12a formed in the pen holder portion 12 does not have to be a roughly semicircular cutout as shown in the first embodiment, and may have another shape, or may not be formed at all.

[0059] 4.2. Modification 2 of the pen holder structure 10 9A to 9C are diagrams showing a second modified example of the pen holder structure 10 according to the first embodiment, in which FIG. 9A is a front view, FIG. 9B is a bottom view, and FIG. 9C is a rear view.

[0060] In Modification 2, the connecting structure 15 is not a hole, but is configured by a sheet-like protruding piece (tab) provided at the x-direction end of the connecting portion 11. The tab here generally means a thin, extending, strip-like member that can be inserted into another structure or protruded for operation. In Modification 2, this tab functions as a connecting structure for detachably connecting the pen holder structure 10 to the cover structure 20. This member is referred to as the "tab member 15."

[0061] 9(a) and (b), the tab member 15 is fixed to the end of the connecting portion 11 via a joint 18. In the example of FIG. 9, the joint 18 is, for example, stitched, but the tab member 15 is joined to the main body of the connecting portion 11 by adhesive, heat welding, or integral molding, thereby ensuring the integrity of the tab member 15 and the connecting portion 11.

[0062] This tab member 15 is used by being inserted into a pocket structure provided on the inside of the cover portion 22 of the cover structure 20. This makes it possible to fix the detachable pen holder structure 10 with a simple configuration without requiring a ring-shaped binding device 23.

[0063] With this configuration, the user can attach the pen holder structure 10 by utilizing the pocket structure of the existing cover structure 20, without needing special tools or modifications to the cover structure. Furthermore, the pen holder structure 10 can be easily removed by simply pulling out the tab member 15 as needed, making it easy to replace or reuse. The y-direction dimension of the tab member 15 can be changed as appropriate. Multiple tab members 15 may be provided on the connecting portion 11. While the tab members 15 extend in the opposite x-direction in FIG. 9, they may also extend in the y-direction.

[0064] The tab member 15 is preferably made of a sheet material such as synthetic resin, metal, leather, or cloth, but since it is inserted into a pocket structure, a material with a certain degree of rigidity is more convenient to use. Also, to improve retention during insertion, the tab member 15 may be processed by providing an uneven surface on the front and back, or by providing a step structure on one side.

[0065] As described above, according to the second modification, a configuration is realized in which the pen holder structure 10 can be easily and reliably attached to the cover structure 20 by combining the tab member 15 and the pocket structure, without using a special binding structure such as a ring. In particular, this configuration can be applied to any type of notebook or binder, and is excellent in terms of product compatibility and versatility.

[0066] 4.3. Other Modifications of the Pen Holder Structure 10 In 4.2 above, an example was described in which the connecting structure 15 of the pen holder structure 10 is realized using the tab member 15, but the connecting structure 15 of the connecting part 11 of the pen holder structure 10 can have other configurations as long as it can be connected to the cover structure 20. For example, the connecting structure 15 can have various configurations, such as adhesion using hook-and-loop fasteners, double-sided tape, a button structure used on clothing, or a structure using magnetic attraction.

[0067] 4.4. Modifications of the Cover Structure 20 In the embodiment, a so-called system organizer has been described as an example of the cover structure 20, but there are no essential limitations on the specific structure of the cover structure 20. As long as the pen holder structure 10 can be connected, the cover structure 20 can have a variety of structures.

[0068] For example, even in a 2-hole or 30-hole loose-leaf binder, the pen holder structure 10 can be easily attached by connecting the connecting portion 11 of the pen holder structure 10 to a ring. In this case, either a configuration having a hole as the connecting structure 15 (basic configuration of embodiment 1) or a configuration having a tab member 15 (variant 2 of embodiment 1) can be applied.

[0069] The penholder structure 10 can also be effectively used in binders of a type that does not use a ring-shaped binding device 23, such as so-called clipboard types or lever file types (types that bind by sandwiching a sheet-like member 30). In these types, the penholder structure 10 is fixed by sandwiching the connecting portion 11 between the binding devices 23 of the sheet-like member 30, and the held portion 13, which is the free end, is sandwiched between the sheet-like members 30 to form a cylindrical space S, which holds a writing instrument. In this way, the penholder structure 10 can be flexibly applied even to types different from the conventional ring-shaped binding device 23 shown in FIG. 5, etc.

[0070] Furthermore, even for a book cover type cover structure 20, i.e., a cover type that covers commercially available books (paperbacks, notebooks, hardcovers, etc.), it is possible to connect the pen holder structure 10 via a pocket structure or the like by using the tab member 15 shown in Modification 2. This makes it possible to add a pen holder function to existing books after the fact.

[0071] In addition, if the medium has a component equivalent to the cover portion 22 and has a connecting portion or pocket structure, such as a laptop computer cover, a tablet case, a whiteboard folder, or a business folder that can store an information terminal, the pen holder structure 10 can be used to add the function of holding a writing instrument.

[0072] 1 to 3 and the like according to the first embodiment, the cover portion 22 is configured to be detachable from the spine portion 21 by a button, but the spine portion 21 and the cover portion 22 may be integrally formed and not detachable. Also, the cover structure 20 does not need to be provided with the cover portion 22 as long as it has a structure that allows the pen holder structure 10 to be connected. For example, the cover structure 20 may be configured only with the binder 23 and the spine portion 21.

[0073] In this way, the pen holder structure 10 has a simple configuration and can be flexibly attached to various types of cover structures 20, improving user convenience. In particular, by selecting the type of connecting structure 15, it is easy to add extensions to existing products.

[0074] Embodiment 2 5. Structure of the pen holder structure 10 The pen holder structure 10 according to the second embodiment is characterized in that the opening and closing direction relative to the booklet structure 100 is different from that of the first embodiment. That is, while the first embodiment is configured such that the clamped portion 13 opens and closes in the x direction, the second embodiment is configured such that the clamped portion 13 can be opened and closed in the y direction.

[0075] Depending on the opening and closing direction, the pen holder structure 10 is arranged along either the upper or lower peripheral edge (end in the y direction) of the booklet structure 100. The example shown in Fig. 10 shows a configuration example in which the pen holder structure 10 is arranged on the upper side of the booklet structure 100, and the clamped portion 13 is configured to be clamped while extending downward (in the -y direction) from the upper end of the sheet-like member 30 held by the booklet structure 100 when the pen holder structure 10 is closed.

[0076] Figure 10 is a front view of a pen holder structure 10 according to embodiment 2. In embodiment 2, the pen holder structure 10 has a sheet shape extending in the y direction. As with embodiment 1, the pen holder structure 10 is configured to include a connecting portion 11, a pen holder portion 12, and a clamped portion 13. The basic configuration of each component, such as the material, joining relationship, and function, is the same, but embodiment 2 differs in that the pen holder structure 10 is configured to extend along the y direction.

[0077] Therefore, the positional relationship between the connecting structure 15 and the direction in which the penholder structure 10 in the open state extends is also different between the second embodiment and the first embodiment. That is, in the first embodiment, the connecting structure 15 is arranged at the end of the penholder structure 10 in the x direction corresponding to the rings 23 (binding devices 23) lined up in the y direction, and the penholder portion 12 and the clamped portion 13 are arranged to extend in the x direction. On the other hand, in the second embodiment, the connecting structure 15 is also arranged at the end of the penholder structure 10 in the x direction, but the penholder portion 12 and the clamped portion 13 are arranged to extend in the y direction from the connecting portion 11. In other words, the connecting portion 11, pen holder portion 12 and clamped portion 13 of the pen holder structure 10 are connected in a row in a first direction (x direction in embodiment 1, y direction in embodiment 2), but in embodiment 1, the connecting structure 15 is arranged at the end of the first direction (x direction) in which the connecting portion 11, pen holder portion 12 and clamped portion 13 are arranged, whereas in embodiment 2, the connecting structure 15 is arranged at the end of the second direction (x direction) perpendicular to the first direction (y direction) in which the connecting portion 11, pen holder portion 12 and clamped portion 13 are arranged.

[0078] According to the second embodiment, the pen holder structure 10 can be configured so that the opening and closing direction of the clamped portion 13 is changed when attached to the cover structure 20. Although the opening and closing direction of the pen holder structure 10 according to the second embodiment is different, the basic configuration and operation are the same as those of the first embodiment, and variations that can be applied according to the user's purpose and preferences can be provided.

[0079] 6. Modification of the Second Embodiment In the pen holder structure 10 according to the second embodiment, as shown in FIG. 10, holes formed in the connecting portion 11 serve as the connecting structure 15. However, as shown in FIG. 9, a tab member 15 may also be used as the connecting structure 15. In this case, as shown in FIG. 9, the tab member 15 is installed so as to extend from one of the x-direction ends of the connecting portion 11 in the opposite direction to the x-direction. However, the tab member 15 may also be installed from the negative y-direction end of the connecting portion 11 toward the y-direction. In this case, the connecting portion 11 has the connecting structure 15 formed at the end in the first direction along which the pen holder structure 10 extends, and the pen holder structure 10 itself has the same configuration as that of the first embodiment.

[0080] Although the present invention has been described above based on the embodiments, the present invention is not limited to the configurations of the above-described embodiments. In short, we would like to emphasize that the gist (technical scope) of the present invention also includes various modifications, applications, and uses that may be made by those skilled in the art as needed.
