Description

The present invention relates to a holder that uses magnetic force to detachably support a rod-shaped object having a magnetic portion, such as a ballpoint pen, mechanical pencil, touch pen, or other writing implement, and to a holder set that combines the holder with the rod-shaped object.

As described in Patent Document 1, for example, a pen holder that can be attached to a booklet-like item such as a notebook has been known, which has a strip, an anti-slip part attached to one side of the strip, and a connection part that connects to the booklet-like item, and when the strip is bent so that the anti-slip part is on the inside, a writing implement storage compartment is formed by the anti-slip part.

Japanese Patent Application Laid-Open No. 2015-77766

However, with the above-mentioned conventional pen holders, when attaching or removing a writing instrument to or from the writing instrument storage compartment of the pen holder, the writing instrument must be moved along its axial direction relative to the storage compartment, creating the problem that attachment and removal are restricted to one direction (axial direction), which is cumbersome.

Furthermore, the pen holder was attached to the booklet-like object by gluing the connecting part of the pen holder to the booklet-like object, which posed the problem of not being able to maintain a stable attachment to the booklet-like object even when the pen holder was used for an extended period of time.

Figure 1(a) shows a conceptual perspective view of a retainer 1 according to an embodiment of the present invention, and Figure 1(b) shows a conceptual side view of the retainer 1 of Figure 1(a) as viewed from the side. Also, Figure 2(a) shows a conceptual plan view of the retainer 1 according to an embodiment of the present invention, Figure 2(b) shows a conceptual plan view of the retainer 1 excluding the receiving surface portion 2a, and Figure 2(c) shows a conceptual front view of the receiving portion main body 2.

1 and 2, this holder 1 includes a receiving body 2 and a clamping body 3. First, the receiving body 2 that constitutes the holder 1 will be described.
(Configuration of receiving body 2)
The receiving portion main body 2 is formed in a generally rectangular shape in a plan view ( FIG. 2( a) ), and has a receiving surface portion 2a forming its surface portion, a back surface portion 2b arranged opposite the back side of the receiving surface portion 2a, a side surface portion 2c connecting the rear ends of the receiving surface portion 2a and the back surface portion 2b in the short direction, and end surface portions 2d, 2d connecting the respective ends of the receiving surface portion 2a and the back surface portion 2b in the long direction.

The receiving surface 2a, back surface 2b, side surface 2c, and end surface 2d are formed by integral molding using a resin material such as polypropylene (PP), polyethylene terephthalate (PET), polyacetal (POM), acrylonitrile butadiene styrene resin (ABS), polycarbonate (PC), polytrimethylene terephthalate (PTT), polybutylene terephthalate (PBT), polycyclohexylene dimethylene terephthalate (PCT), polystyrene (PS), cellulose propionate (CP), polyarylate, polycarbonate, acrylonitrile styrene copolymer resin (AS), or low-density polyethylene (LDPE).

As shown in Figures 2(b) and 2(c), the receiving body 2 has, in the space surrounded by the receiving surface 2a, back surface 2b, side surface 2c, and left and right end surface portions 2d, 2d, sections A, A that house the left and right sound-absorbing members 6, 6, respectively, sections B, B that house the left and right magnets 5, 5, respectively, and section C that houses the mounting portion 3d of the clamping body 3.

(Sections A, A of receiving body 2)
The compartments A, A are defined by left and right first partition walls 21, 21 formed inside the clamping body 3, and each accommodates a left and right sound deadening member 6, 6. The left and right first partition walls 21, 21 defining each compartment A, A are disposed at a predetermined interval in the longitudinal direction from the left and right end surface portions 2 d, 2 d, and are formed to rise vertically so as to connect the inner surface of the back surface portion 2 b and the inner surface of the receiving surface portion 2 a ( FIG. 2( c) ).

Openings corresponding to the sections A, A are formed at the front end of the receiving body 2 in the short direction, and sound-absorbing members 6, 6 are inserted through these openings. The sound-absorbing members 6, 6 housed in the sections A, A act and function to reduce the contact noise (impact noise) when the writing instrument 4 is attached to the holder 1.

Specifically, when a writing instrument 4 is supported (held) on the receiving surface 2a of the receiving body 2 constituting the holder 1, the magnets 5, 5 housed and held in the sections B, B of the receiving body 2 magnetically attract the barrel 4a made of a magnetic material of the writing instrument 4, causing it to abut against the receiving surface 2a. At this time, the holder 1 makes a contact sound (impact sound) when it abuts against the writing instrument 4, but the sections A, A of the receiving body 2 house and hold sound-absorbing members 6, 6, and the contact sound (impact sound) that resonates in the space between the sections A, A is damped by these sound-absorbing members 6, 6, thereby reducing the contact sound (impact sound).
Although nonwoven fabric, foam resin, or the like can be used as the sound deadening members 6, 6, the material is not limited thereto, and synthetic resins such as polypropylene (PP), polyethylene terephthalate (PET), polyacetal (POM), acrylonitrile butadiene styrene resin (ABS), polycarbonate (PC), polypropylene (PP), etc. can also be used.

(Sections B, B of receiving body 2)
The compartments B, B are defined by the left and right first partition walls 21, 21 and left and right second partition walls 22, 22 formed inside the clamping body 3, and each accommodates a left and right magnet 5, 5. The left and right second partition walls 22, 22 are disposed a predetermined distance away from the left and right first partition walls 21, 21, respectively, toward the center in the longitudinal direction, and are formed to rise vertically so as to connect the inner surface of the back surface portion 2 b and the inner surface of the receiving surface portion 2 a ( FIG. 2( c) ).

The front end of the receiving body 2 in the short direction is formed with openings corresponding to the sections B, B, and magnets 5, 5 are inserted through the openings. The magnets 5, 5 housed in the sections B, B act and function to magnetically attract and support (hold) the writing instrument 4 having a barrel 4a made of a magnetic material to the receiving surface 2a of the receiving body 2 constituting the holder 1.
The magnets 5, 5 may be neodymium magnets or ferrite magnets.

The gap between the opposing inner surfaces of the first partition walls 21 and second partition walls 22 that define each compartment B is set to a distance that allows the magnets 5 to be positioned and held from the left and right, and is set to, for example, approximately the same as the diameter of the magnets 5 or slightly larger than the diameter of the magnets 5. This allows the magnets 5 to be stably housed and held in the compartments B.
Furthermore, in the above embodiment, as shown in the partially enlarged view of Figure 2(b) (compartment B on the left), protruding ribs 21a and 22a are provided on the inner surfaces of the first partition wall 21 and the second partition wall 22 on the compartment B side, respectively, and these ribs 21a and 22a enable the magnet 5 in compartment B to be stably held in place (compartment B on the right is configured in the same way).

In addition, in the above embodiment, upper members 23, 23 are provided in each compartment B, B, connecting the upper portions of the left and right first partition walls 21, 21 and the left and right second partition walls 22, 22, and are configured to position and hold the magnets 5, 5 from above. By providing such upper members 23, 23, the magnets 5, 5 can be housed and held more stably in each compartment B, B.

The upper members 23, 23 are provided to connect the upper portions of the left and right first partition walls 21, 21 and the left and right second partition walls 22, 22, but they can also be configured as lower members that connect the lower portions of the left and right first partition walls 21, 21 and the left and right second partition walls 22, 22.

The partition walls 21, 21, 22, 22 and the upper members 23, 23 are formed by integral molding using a resin material together with the receiving surface portion 2a, the back surface portion 2b, the side surface portion 2c and the end surface portions 2d, 2d.
In addition, the receiving surface portion 2a, the back surface portion 2b, the side surface portion 2c, the end surface portions 2d, 2d, the partition walls 21, 21, 22, 22 and the upper members 23, 23 can each be constructed as separate bodies and then connected to form an integrated unit.

By forming the partition walls 21, 21, 22, 22 and upper members 23, 23, the rigidity of the receiving body 2 is improved and deformation of the receiving surface 2a of the receiving body 2 can be prevented, allowing the receiving body 2 to stably support (hold) the writing instrument 4. Furthermore, since there is space inside the receiving body 2, the holder 1 can be made lighter.

(Compartment C of receiving body 2)
The compartment C is defined by left and right second partition walls 22, 22 formed inside the receiving portion main body 2, and accommodates the mounting portion 3d of the clamping main body 3.
An opening corresponding to the section C is formed at the front end of the receiving body 2 in the short side direction, and the mounting section 3d of the clamping body 3 is inserted through the opening. The mounting section 3d of the clamping body 3 is fixed to the inner surface of the back surface 2b of the receiving body 2.

2(c), the left and right second partition walls 22, 22 are composed of upper partition wall portions 22U, 22U constituting the upper portions of the second partition walls 22, 22, and lower partition wall portions 22D, 22D constituting the lower portions of the second partition walls 22, 22. The thickness of the upper partition wall portions 22U, 22U is configured to be greater than the thickness of the lower partition wall portions 22D, 22D.
In addition, the inner surface of the upper partition wall portion 22U, 22U on the compartment C side is thicker than the inner surface of the lower partition wall portion 22D, 22D on the compartment C side, and steps 220, 220 are formed on the inner surfaces of the left and right second partition walls 22, 22 on the compartment C side so that the lower parts are recessed.

In section C, the distance between the opposing inner surfaces of the lower partition wall portions 22D, 22D (the distance in the left-right direction in Figure 2(c)) is set to a distance that positions and holds the mounting portion 3d of the clamping body 3 in the left-right direction, and the height of the lower partition wall portions 22D, 22D (the height in the up-down direction in Figure 2(c)) is set to a height that positions and holds the mounting portion 3d of the clamping body 3 in the up-down direction.
Therefore, the mounting portion 3d of the clamping body 3 can be positioned in the left-right and up-down directions by each step 220, 220 formed on the inner surface of the compartment C side of the left and right second partition walls 22, 22, and fixed to the inner surface of the back surface portion 2b of the receiving body 2 in a stable holding state.

In the above embodiment, a protrusion 24 extending from the side surface 2c toward the opening is provided on the inner surface of the back surface 2b of the receiving body 2 in section C, and the protrusion 24 is configured to fit into a notch 3d1 formed in the mounting portion 3d of the clamping body 3, which will be described later. By providing this protrusion 24, the mounting portion 3d of the clamping body 3 can be fixed to the inner surface of the back surface 2b of the receiving body 2 in a state where it is positioned and held more stably.
The protrusion 24 is formed by integral molding of a resin material together with the receiving surface 2a, the back surface 2b, the side surface 2c, and the end surface 2d, 2d. Alternatively, the protrusion 24 may be formed as a separate body and fixed to the back surface 2b.

(Configuration of receiving surface portion 2a of receiving portion main body 2)
The receiving surface portion 2a of the receiving body 2 forms a support surface (holding surface) that supports and holds the magnetic barrel 4a of the writing instrument 4, which will be described later, by the magnetic force of the magnets 5, 5 held in sections B, B of the receiving body 2.

(Protrusion 2a1 of receiving surface portion 2a)
1(a) and 1(b), the receiving surface portion 2a has a protrusion 2a1 extending in the longitudinal direction formed on the rear end side in the lateral direction thereof. In addition, the receiving surface portion 2a has a flat surface 2a3 on the front end side (opening side) of the receiving surface portion 2a in the lateral direction from the protrusion 2a1. Therefore, the receiving portion main body 2 is formed to have a generally L-shape in side view as a whole, as shown in FIG. 1(b), with the shape of the flat surface 2a3 of the receiving surface portion 2a combined with the shape of the protrusion 2a1.

The protrusion 2a1 functions to restrict movement of the writing instrument 4, which is supported (held) by magnetic force on the receiving surface 2a, toward the rear end in the lateral direction (movement in the radial direction and along the flat surface 2a3). Specifically, for example, when an external force in the lateral direction or an external force in the circumferential direction of the barrel 4a is applied by a finger or the like to the writing instrument 4, which is supported (held) by magnetic force on the receiving surface 2a, the writing instrument 4 will attempt to move toward the rear end in the lateral direction on the receiving surface 2a, but this movement will be restricted by contact with the protrusion 2a1.
Therefore, even if an external force in the short direction is inadvertently applied by a finger or the like to the writing implement 4 supported (held) on the receiving surface portion 2a, it is possible to prevent the writing implement 4 from immediately falling.

Furthermore, when removing the writing instrument 4 that is magnetically supported (held) on the receiving surface 2a from the short side, the writing instrument 4 can be easily removed from the short side of the receiving surface 2a by applying an external force to the writing instrument 4 sufficient to overcome the protruding portion 2a1.

As shown in FIG. 1(a), the protrusion 2a1 in the above embodiment is provided extending over the entire longitudinal direction of the receiving surface portion 2a, but it may also be provided, for example, only in the central portion in the longitudinal direction, or multiple protrusions may be provided spaced apart in the longitudinal direction.
Furthermore, the protrusion 2a1 may be formed in any shape that restricts the movement of the writing implement 4 in the short direction on the receiving surface 2a, and the side view shape of the receiving body 2 is not limited to a roughly L-shape when viewed from the side.
Furthermore, the external force required to remove the writing implement 4 from the short side can be designed by appropriately adjusting the magnetic force of the magnets 5, 5 and the height and shape of the protruding portion 2a1.

Therefore, the writing implement 4 supported (held) on the receiving surface portion 2a can be stably supported (held) by the protruding portion 2a1, and can be easily removed from the receiving surface portion 2a in the short direction.

(Protrusions 2a2, 2a2 of receiving surface portion 2a)
Furthermore, a pair of protrusions 2a2, 2a2 are provided on the longitudinal end face portions 2d, 2d side of the receiving surface portion 2a of the receiving portion main body 2, which come into contact with step portions 4a1, 4a2 of the writing instrument 4, which will be described later, thereby restricting the axial movement of the writing instrument 4. The distance between the pair of protrusions 2a2, 2a2 is set to be greater than the length of the barrel 4a of the writing instrument 4.
When an external axial force, for example from a finger, acts on the writing instrument 4 supported (held) by magnetic force on the receiving surface portion 2a, causing the writing instrument 4 to move in the longitudinal direction of the receiving body 2, the step portions 4a1, 4a2 of the writing instrument 4 come into contact with the protrusions 2a2, 2a2 provided on the receiving body 2, thereby restricting the movement.

As a result, even if an inadvertent external force in the axial direction is applied by a finger or other force to the writing instrument 4 supported (held) on the receiving surface portion 2a, it is possible to prevent the writing instrument 4 from immediately falling. The writing instrument 4 supported (held) on the receiving surface portion 2a can be stably supported (held) by the pair of protrusions 2a2, 2a2.

The distance between the pair of protrusions 2a2, 2a2 can be set to be greater than the length of the barrel 4a of the writing instrument 4. For example, by setting the distance between the pair of protrusions 2a2, 2a2 slightly greater than the length of the barrel 4a, the barrel 4a of the writing instrument 4 can be positioned at a predetermined position (predetermined position) on the receiving surface 2a, and the writing instrument 4 can be supported and held on the receiving surface 2a in a visually balanced manner.

Next, the clamping body 3 constituting the holder 1 according to the present invention will be described.
(Configuration of clamping body 3)
Figure 3(a) shows a conceptual oblique view of the clamping body 3 according to an embodiment of the present invention, Figure 3(b) shows a conceptual plan view of the clamping body 3, and Figure 3(c) shows a conceptual side view of the clamping body 3.
The clamping body 3 has a first clamping portion 3a, a second clamping portion 3b, connecting portions 3c, 3c, and an attachment portion 3d, and is formed by pressing a plate made of a resilient metal such as iron or stainless steel. For example, by using a metal plate with a thickness of 0.5 to several millimeters, it is possible to configure a clamping body 3 that has good elastic restoring force against bending and excellent durability.

(First clamping part 3a, second clamping part 3b)
The first clamping portion 3a and the second clamping portion 3b are formed by being folded at the connecting portion 3c, 3c so as to face each other to form a clamping portion, and the first clamping portion 3a and the second clamping portion 3b are configured to clamp the back cover 7a (object) of the booklet 7 in a freely detachable manner.
The length 3aL of the first clamping portion 3a in the short side direction is longer than the length 3bL of the second clamping portion 3b in the short side direction, so that the back cover 7a (object) of the booklet 7 can be easily inserted into the space between the first clamping portion 3a and the second clamping portion 3b and clamped. Specifically, as shown in Fig. 3(b), the first clamping portion 3a is positioned so that the edge of the back cover 7a of the booklet 7 abuts against a portion of the first clamping portion 3a that is located further forward than the second clamping portion 3b on the short side front end side, and the back cover 7a positioned in this manner is pushed toward the short side rear end side of the space between the first clamping portion 3a and the second clamping portion 3b, so that the holder 1 can be easily attached to the back cover 7a.

In addition, two protrusions 3a1, 3a1 that protrude toward the second clamping portion 3b are formed on the inner surface of the first clamping portion 3a at a distance in the longitudinal direction of the first clamping portion 3a (left-right direction in Figure 3(b)). These protrusions 3a1, 3a1 form contact areas when the back cover 7a is clamped, and the back cover 7a is clamped between the protrusions 3a1, 3a1 of the first clamping portion 3a and the second clamping portion 3b, so that the holder 1 is stably held to the back cover 7a.

In the above embodiment, the first clamping portion 3a has two protrusions 3a1, 3a1 formed on its inner surface, protruding toward the second clamping portion 3b, spaced apart in the longitudinal direction of the first clamping portion 3a, but the number and location of these protrusions can be set as desired. In the above embodiment, the protrusions 3a1, 3a1 are provided on the first clamping portion 3a, but they may also be provided on the second clamping portion 3b.

(Connection parts 3c, 3c)
The connecting portions 3c, 3c of the clamping body 3 connect the first clamping portion 3a and the second clamping portion 3b, and position the first clamping portion 3a and the second clamping portion 3b opposite each other. As shown in Fig. 2(b), the connecting portions 3c, 3c are positioned so as to be supported by the inner surface of the front end side in the short direction of the back surface 2b of the receiving body 2, and are positioned so as to close the openings corresponding to the sections B, B of the receiving body 2.
Therefore, the clamping body 3 is supported by the receiving body 2 at the attachment portion 3d and the connecting portions 3c, 3c, and can be stably supported and fixed to the receiving body 2. Furthermore, the magnets 5, 5 housed and held in the sections B, B of the receiving body 2 are housed and held even more stably because their openings are closed by the connecting portions 3c, 3c.

(Mounting portion 3d)
The attachment portion 3d of the clamping body 3 is formed contiguously with the first clamping portion 3a on approximately the same plane, and serves as an attachment portion that is fixed to the inner surface of the back surface 2b of the receiving body 2 (FIG. 2(b)). The attachment portion 3d is inserted through an opening corresponding to the section C of the receiving body 2, and is fixed to the inner surface of the back surface 2b of the receiving body 2.
Furthermore, the mounting portion 3d is formed with a notch 3d1 that fits into a protrusion 24 provided on the inner surface of the back surface 2b of the receiving portion main body 2. By fitting this notch 3d1 into the protrusion 24 provided on the inner surface of the back surface 2b of the receiving portion main body 2, the clamping main body 3 can be stably supported and fixed in a state where it is positioned and held on the receiving portion main body 2.

In the above embodiment, the clamping body 3 is formed by pressing a plate made of a resilient metal such as iron or stainless steel. However, the material can be metal or plastic. For example, the clamping body 3 can be integrally molded using materials such as polypropylene (PP), polyethylene terephthalate (PET), polyacetal (POM), acrylonitrile butadiene styrene (ABS), polycarbonate (PC), polytrimethylene terephthalate (PTT), polybutylene terephthalate (PBT), polycyclohexylene dimethylene terephthalate (PCT), polystyrene (PS), cellulose propionate (CP), polyarylate, polycarbonate, acrylonitrile styrene copolymer (AS), and low-density polyethylene (LDPE). The clamping body 3 can be made of a variety of materials that have good elastic recovery force when bent and are not easily damaged.

In addition, while the above embodiment describes a clamping body 3 that detachably clamps the back cover 7a (object) of a booklet 7, the clamping body 3 can be configured to be attached to various objects, such as the flat surface of a notebook computer or the main body of a mobile terminal (smartphone). In such cases, the configuration of the clamping body 3 (for example, the clamping force, clamping width, material selection, etc. of the clamping section consisting of the first clamping portion 3a, the second clamping portion 3b, and the connecting portions 3c, 3c) can be adjusted and designed appropriately to suit the thickness, material, etc. of the object.

Next, an example of the writing implement 4 supported (held) by the holder 1 according to the embodiment of the present invention will be described.
(Configuration of writing instrument 4)
FIG. 4( a ) shows a conceptual plan view of a writing instrument 4 according to an embodiment of the present invention, and FIG. 4( b ) shows a conceptual side view of the writing instrument 4 .
This writing instrument 4 comprises a barrel 4a, a tip 4b provided at the front end of the barrel 4a, a tail plug 4c provided at the rear end of the barrel 4a, and a refill (not shown) housed within the barrel 4a so as to protrude from the tip 4b. For example, by operating the tail plug 4c, the refill is advanced and the front end of the refill protrudes forward from the tip 4b.
The tail plug 4c is formed in a cylindrical shape with a bottom, and a strap 4d is attached to the bottom.

The barrel 4a of the writing implement 4 is made of a magnetic material, such as a metal material such as iron, that is attracted by the magnetic force of the magnets 5, 5 held in the sections B, B of the receiving body 2, and is supported (held) on the receiving surface 2a of the receiving body 2.
In the above embodiment, the entire barrel 4a is made of a magnetic material such as a metal material, but for example, a portion of the barrel 4a may be made of a magnetic material such as a metal material, and the remaining portion may be made of a synthetic resin material, or the entire barrel 4a may be made of a synthetic resin material with a magnetic material or magnet placed inside, or the entire barrel 4a may be made of a synthetic resin material mixed with magnetic particles or magnetic powder.

A nosepiece 4b is provided at the front end of the barrel 4a, and the diameter of the barrel 4a is made larger than the diameter of the nosepiece 4b on the barrel 4a side, thereby forming a step 4a1 at the boundary between the barrel 4a and the nosepiece 4b. Furthermore, a tail plug 4c is provided at the rear end of the barrel 4a, and the diameter of the barrel 4a is made larger than the diameter of the tail plug 4c on the barrel 4a side, thereby forming a step 4a2 at the boundary between the barrel 4a and the tail plug 4c.
These step portions 4a1, 4a2 come into contact with the protrusions 2a2, 2a2 formed on the receiving surface portion 2a of the receiving portion main body 2, thereby restricting the movement of the writing implement 4 in the axial direction.

Next, an example of a holder set that combines the holder 1 according to an embodiment of the present invention with a writing implement 4 will be described.
(Holder set)
Figures 5(a) and (b) show an example of a holder set according to an embodiment of the present invention, where Figure 5(a) is a conceptual plan view showing an example of use in which a holder 1 supporting (holding) a writing instrument 4 is attached to a booklet 7, and Figure 5(b) shows a conceptual side view of Figure 5(a).

The first clamping portion 3a and the second clamping portion 3b of the clamping body 3 of the holder 1 are attached to the back cover 7a (object) of the booklet 7. Specifically, the first clamping portion 3a is positioned so that the edge of the back cover 7a of the booklet 7 abuts against a portion of the front end side of the first clamping portion 3a in the short side direction that is located further forward than the second clamping portion 3b, and the back cover 7a positioned in this manner is pushed toward the rear end side in the short side direction of the space between the first clamping portion 3a and the second clamping portion 3b, thereby easily attaching the holder 1 to the back cover 7a.
Thereafter, the writing instrument 4 can be supported (held) by magnetic force on the receiving surface portion 2a of the holder 1 attached to the back cover 7a of the booklet 7, allowing the writing instrument 4 to be held and carried together with the booklet 7.

Furthermore, the receiving surface 2a of the receiving portion main body 2 that constitutes the holder 1 is formed with a protrusion 2a1 that extends longitudinally from the rear end in the short side direction. The writing instrument 4 supported (held) by the receiving surface 2a is restricted from moving toward the rear end in the short side direction, and the protrusion 2a1 allows the writing instrument 4 supported (held) by the receiving surface 2a to be stably supported (held). In addition, the movement of the writing instrument 4 supported (held) by the receiving surface 2a is restricted by the presence of a booklet 7 such as a notebook or planner located at the front end in the short side direction (see Figure 5(b)), further stably supporting (holding) it on the receiving surface 2a.

Furthermore, the receiving surface 2a of the receiving body 2 is provided with a pair of protrusions 2a2, 2a2 on the longitudinal end surfaces 2d, 2d of the receiving surface 2a, which are configured to restrict the movement of the stepped portions 4a1, 4a2 of the writing instrument 4. Therefore, even if an inadvertent external force (such as an external force from a finger) acts in the barrel axis direction on the writing instrument 4 supported (held) by the receiving surface 2a, the movement of the stepped portions 4a1, 4a2 of the writing instrument 4 is restricted by the protrusions 2a2, 2a2, and the writing instrument 4 supported (held) by the receiving surface 2a can be stably supported (held).

When removing the writing instrument 4 held on the receiving surface 2a of the receiving body 2 from the receiving surface 2a for use, the writing instrument 4 can be easily removed from the receiving surface 2a by, for example, applying an external force (external force toward the rear end in the short direction) to the writing instrument 4 with a finger or the like so that it overcomes the protruding portion 2a1. The writing instrument 4 can also be easily removed by pulling up the strap 4d attached to the tail plug 4c of the writing instrument 4 so as to pull it away from the receiving surface 2a.

Furthermore, when the writing instrument 4 is supported (held) on the receiving surface 2a of the holder 1, a contact sound (impact sound) is generated when the holder 1 and the writing instrument 4 come into contact. However, because the sound-absorbing members 6, 6 are housed and held in the sections A, A of the receiving body 2, this contact sound (impact sound) can be reduced.

The present invention is not limited to the above-described embodiments and can be modified as appropriate without departing from the spirit of the present invention.
