[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In this specification and the drawings, components having substantially the same functional configurations are denoted by the same reference numerals, and duplicated descriptions will be omitted.

[0011] In addition, to facilitate understanding, the scale of each part in the drawings may differ from the actual scale. In directions such as parallel, right angle, orthogonal, horizontal, vertical, up / down, left / right, deviations are permitted to the extent that do not impair the effects of the embodiment. The shape of the corners is not limited to right angles, and may be rounded in an arch shape. Parallel, right angle, orthogonal, horizontal, and vertical may include approximately parallel, approximately right angle, approximately orthogonal, approximately horizontal, and approximately vertical.

[0012] <Information display system 1> Fig. 1 is a perspective view of an information display system 1 according to this embodiment. Fig. 2 is an enlarged perspective view of the information display system according to this embodiment. Specifically, Fig. 2 is an enlarged perspective view of a portion A in Fig. 1.

[0013] For convenience of explanation, a virtual three-dimensional coordinate system (XYZ Cartesian coordinate system) consisting of mutually orthogonal X-axis, Y-axis, and Z-axis (XYZ axes) may be set in the drawings. However, this coordinate system is defined for the purpose of explanation and does not limit the attitude of the information display system 1 and the information display device 10 described later.

[0014] In the present disclosure, unless otherwise specified, the X-axis direction is a direction parallel to the screen 10A of the information display device 10 and is the short-side direction of the screen 10A. The Y-axis direction is a direction parallel to the screen 10A of the information display device 10 and is the long-side direction of the screen 10A. In other words, the XY plane parallel to the X-axis direction and the Y-axis direction is a plane parallel to the screen 10A of the information display device 10. The Z-axis is a direction perpendicular to the X-axis and the Y-axis. In other words, the YZ plane parallel to the Y-axis direction and the Z-axis direction is a plane perpendicular to the screen 10A of the information display device 10. Similarly, the ZX plane parallel to the X-axis direction and the Z-axis direction is a plane perpendicular to the screen 10A of the information display device 10.

[0015] The X-axis direction may be referred to as the left-right direction, the Y-axis direction as the up-down direction, and the Z-axis direction as the thickness direction. Furthermore, with respect to an object, the +X side may be referred to as the right side, the -X side as the left side, the +Y side as the top side, the -Y side as the bottom side, the +Z side as the front side, and the -Z side as the back side. Viewing the information display device 10 from the +Z side may be referred to as viewing from the front. Viewing the information display device 10 from the -Z side may be referred to as viewing from the back.

[0016] The information display system 1 includes an information display device 10 and a pen holder 30. A user inputs information to the information display device 10 via an electronic pen 20. The electronic pen 20 is used for inputting information to the information display device 10. A core 21, which is the pen tip of the electronic pen 20, contacts a screen 10A of the information display device 10. When the core 21 of the electronic pen 20 contacts the screen 10A, the information display device 10 detects the input from the electronic pen 20. The core 21, which is the pen tip of the electronic pen 20, is replaceable.

[0017] The pen holder 30 is attached to the information display device 10. The pen holder 30 also detachably holds the electronic pen 20. For example, when the electronic pen 20 is not in use, the user attaches the electronic pen 20 to the pen holder 30. When the electronic pen 20 is in use, the user removes the electronic pen 20 from the pen holder 30 and uses it.

[0018] The information display system includes the information display device 10 and the pen holder 30, and may further include the electronic pen 20.

[0019] [Information display device 10] The information display device 10 displays the screen of a PC (Personal Computer) or the like. Furthermore, by using an electronic pen 20, characters and figures can be freely written on the image displayed on the screen 10A of the information display device 10. Furthermore, one of the features of the information display device 10 according to this embodiment is its thinness, as shown in Figs. 1 and 2. The information display device 10 according to this embodiment is designed to be thin and lightweight, making it possible to create a display product that is highly portable even when using a display with a large number of inches.

[0020] 1 and 2, another feature of the information display device 10 according to this embodiment is that the back surface is completely flat. This makes it possible to place the information display device 10 flat on a desk, for example, so that multiple people can gather around the information display device 10 and hold a discussion. The information display device 10 can also accommodate input from multiple electronic pens 20 so that multiple people can write at the same time. Furthermore, both the main body of the information display device 10 and the electronic pens 20 are dustproof and waterproof so that the information display device 10 can be used outdoors.

[0021] The information display device 10 according to this embodiment does not have a space for storing the electronic pen 20. Therefore, the information display system 1 includes a dedicated pen holder 30 that is attached to the information display device 10. The user attaches the pen holder 30 to a predetermined position on the information display device 10.

[0022] The predetermined position for attaching the pen holder 30 is, for example, an opening hole 11h for a security lock formed in the frame 11 on the side surface of the information display device 10. The information display device 10 has opening holes 11h in multiple locations on the side surface of the housing.

[0023] The information display device 10 can be installed in various positions, such as lying flat, leaning against a wall in a vertical position, leaning against a wall in a horizontal position, etc. Therefore, the information display device 10 has openings 11h in multiple locations so that the user can freely select the installation locations of the pen holder 30 and the security lock when installing the information display device 10 in a desired position. The information display device 10 has openings 11h in a total of seven locations.

[0024] [Pen holder 30] Next, the pen holder 30 will be described. Fig. 3 is a perspective view of the pen holder for the information display device according to this embodiment. Fig. 4 is a side view of the pen holder for the information display device according to this embodiment. Specifically, Fig. 4 is a side view seen from the -Z side of Fig. 3. Fig. 5 is a perspective view of the pen holder for the information display device according to this embodiment seen from a different direction than Fig. 3.

[0025] The pen holder 30 has a pen holding section 31, a lead puller 32, a replacement lead storage section 33, and an attachment section 34. The pen holder 30 is made of a resin such as polyamide (nylon), polyethylene, polyacetal, polycarbonate, etc. As the width of the clamping section in the lead puller is narrower than the lead of the electronic pen as described below, the resin forming the pen holder 30 is preferably a soft resin that is easily deformed. The pen holder 30 is integrally formed from the same material, for example, by injection molding.

[0026] (Pen holder 31) The pen holding portion 31 holds the electronic pen 20. The pen holding portion 31 holds the electronic pen 20 by sandwiching the sides of the electronic pen 20.

[0027] (Core removal part 32) The core puller 32 serves as a tool for pulling out the core 21 of the electronic pen 20. The core puller 32 has a shape in which a part of the pen holder 30 is cut out. The specific configuration of the core puller 32 will be described later.

[0028] The information display system 1 according to this embodiment is structured so that the pen holder 30 is provided with a lead puller 32. The pen holder 30 is an essential item for holding the electronic pen 20, and so there is little risk of it being lost. In addition, since the user carries the pen holder 30 together with the information display device 10, the user can reliably use the lead puller 32 of the pen holder 30 to replace the lead whenever desired.

[0029] On the other hand, when pulling out the core of an electronic pen such as the electronic pen 20, a removal jig 60 as shown in FIG. 6 is usually used. The removal jig 60 in FIG. 6 is a leaf spring-like metal sheet with one end cut into a semicircular shape to have a removal part 61. The removal jig 60 is used to grasp and pull out the core with the removal part 61. Note that the removal jig 60 shown in FIG. 6 is an example of a removal jig with only one end cut into a semicircular shape, but in some cases both ends may be cut into a semicircular shape. In addition, both ends may be flat, or one end or both ends may be jagged.

[0030] A tool such as the removal tool 60 shown in Fig. 6 is not carried with the information display device 10 but is stored somewhere. Therefore, even if a user wishes to replace the lead at a location where the portable information display device 10 is carried, there may be cases where the tool is not available at the location and replacement is not possible. The information display system 1 according to this embodiment has a lead removal unit 32 in the pen holder 30 carried with the information display device 10, so that the user can reliably replace the lead whenever they want.

[0031] In particular, in the case of a method in which a removal tool 60 as shown in FIG. 6 is included in the package, there is a risk that the removal tool 60 will be lost if it is not properly managed. This is unlikely to be a problem if the device is managed by an individual, since the individual also manages the tool. For example, a smartphone or tablet compatible with an electronic pen may be packaged with a tool as shown in FIG. 6. On the other hand, in the case of a shared device, since the administrator and the user are different, there may be cases where the user does not know where the tool is managed, and the tool may be lost or may not be able to be found when the user wants to use it, making it impossible to replace the lead.

[0032] (Refill cartridge storage compartment 33) Next, the replacement lead storage section 33 will be described.

[0033] 7, 8 and 9 are diagrams illustrating the replacement lead storage section 33 of the pen holder 30 for the information display device according to this embodiment.

[0034] The lead storage section 33 includes a lid 33a. When the handle 33b of the lid 33a is pushed in the direction of the arrow Aa in FIG. 7, the lid 33a is detached. The lead storage section 33 includes a lead storage section 33c inside the lid 33a. The lead storage section 33c is structured to be able to store a plurality of lead 21m as shown in FIG. 9. Although five lead 21m are stored in FIG. 9, the number of lead 21m stored is not limited to five, and it is sufficient that at least one lead 21m can be stored. The lead storage section 33c is structured so that the lead 21m is simply placed in the box-shaped lead storage section 33c without holding the lead 21m when stored.

[0035] The lid 33a is disposed so as to face the frame 11 on the side of the information display device 10. This is to prevent access to the lid 33a when the pen holder 30 is attached to the information display device 10. When the pen holder 30 is attached, the opening and closing operation of the lid 33a interferes with the frame 11 on the side of the information display device 10, so the lid 33a cannot be opened or closed. This eliminates the risk of the lid 33a accidentally opening, i.e., scattering the refills 21m.

[0036] Incidentally, even if the pen holder 30 is provided with only the lead puller 32, it can only pull out the lead, but the lead cannot be replaced without the essential replacement lead 21m (described later) of the electronic pen 20. Therefore, it can be said that it is necessary to manage and carry around the replacement lead 21m.

[0037] In the information display system 1 according to this embodiment, the pen holder 30 also includes a replacement lead storage section 33 that can store a replacement lead 21m. Therefore, if the pen holder 30 is carried around, the refill can be replaced whenever desired.

[0038] (Mounting part 34) The attachment portion 34 is coupled to an opening 11h for a security lock formed in the information display device 10. The pen holder 30 is attached to the information display device 10 by coupling the attachment portion 34 to the opening 11h.

[0039] [Structure of the core removal section 32] Next, a description will be given of the structure of the lead puller 32. Figures 10 and 11 are diagrams illustrating the lead puller 32 of the pen holder 30 for an information display device according to this embodiment.

[0040] As shown in Figure 10, the pen holder 30 has a lead puller 32 near the refill lead storage section 33. From the viewpoint of usability, the lead puller 32 is provided near the refill lead storage section 33. Because the action of pulling out the lead 21 and the action of inserting a new lead 21 are a series of actions, it is located nearby to provide a structure that is easy for the user to understand. Also from the viewpoint of usability, the pen holder 30 has an engraving 35.

[0041] 11 is an enlarged view of the core puller 32. The core puller 32 is substantially U-shaped with a portion of the plate-like wall 30W cut out in the Y-axis direction. The core puller 32 has a first clamping portion 32s1 and a second clamping portion 32s2 each having a two-stage groove shape.

[0042] The first clamping portion 32s1 has a first end 32L11 and a second end 32L12 that extend linearly in the +Y direction of the Y axis direction. The first end 32L11 and the second end 32L12 are positioned to face each other. The second end 32L12 is positioned away from the first end 32L11 on the -X side of the X axis direction that intersects with the Y axis direction.

[0043] Note that "straight line" does not necessarily mean being strictly straight, but means being straight within standard manufacturing tolerances, for example.

[0044] The length H1 of the first clamping portion 32s1, that is, the length in the Y-axis direction of each of the first end portion 32L11 and the second end portion 32L12, is equal to or greater than the radius of the core 21.

[0045] 11 indicates the diameter of the lead 21. The width L1 of the first clamping portion 32s1, i.e., the distance in the X-axis direction between the first end 32L11 and the second end 32L12, is shorter than the diameter of the lead 21. Because the width L1 of the first clamping portion 32s1 is shorter than the diameter of the lead 21, the first clamping portion 32s1 clamps the lead 21 when the lead 21 is inserted from the opening 32p in the +Y direction in the Y-axis direction.

[0046] The second clamping portion 32s2 is located on the +Y side, i.e., the back side, of the first clamping portion 32s1. The second clamping portion 32s2 has a third end portion 32L21 and a fourth end portion 32L22 that extend linearly in the +Y direction of the Y axis direction. The third end portion 32L21 and the fourth end portion 32L22 are located opposite each other. The fourth end portion 32L22 is located away from the third end portion 32L21 on the -X side of the X axis direction that intersects with the Y axis direction.

[0047] The length H2 of the second clamping portion 32s2, that is, the length in the Y-axis direction of each of the third end portion 32L21 and the fourth end portion 32L22, is equal to or greater than the radius of the core 21.

[0048] 11 indicates the diameter of the lead 21. The width L2 of the second clamping portion 32s2, i.e., the distance in the X-axis direction between the third end 32L21 and the fourth end 32L22, is shorter than the diameter of the lead 21. Since the width L2 of the second clamping portion 32s2 is shorter than the diameter of the lead 21, the second clamping portion 32s2 clamps the lead 21 when the lead 21 is inserted from the opening 32p in the +Y direction in the Y-axis direction.

[0049] Furthermore, the width L2 of the second clamping portion 32s2 is shorter than the width L1 of the first clamping portion 32s1.

[0050] The pen holder 30 according to this embodiment has a two-stage configuration having a first clamping portion 32s1 and a second clamping portion 32s2. The two-stage configuration of the pen holder 30 according to this embodiment having the first clamping portion 32s1 and the second clamping portion 32s2 can accommodate variations in the diameter of the lead 21. Furthermore, the two-stage configuration of the pen holder 30 according to this embodiment having the first clamping portion 32s1 and the second clamping portion 32s2 makes it easier to guide the first clamping portion 32s1 into the narrower second clamping portion.

[0051] The number of stages of the lead pulling section 32 is not limited to two. For example, the number of stages of the lead pulling section 32 may be three or more, or may be one.

[0052] Here, the shape of the groove will be described. Fig. 12 is a diagram for explaining the shape of the lead puller 32 of the pen holder 30 for an information display device according to this embodiment. In Fig. 12, end 32L1 and end 32L2 are explained as examples of the ends of the lead puller 32. Fig. 13 is a diagram for explaining the shape of the lead puller 32z of a pen holder of a reference example.

[0053] 12, the pen holder 30 according to this embodiment has a clamping portion 32s having end portions 32L1 and 32L2 that extend linearly in the +Y direction of the Y-axis. End portions 32L1 and 32L2 are substantially parallel. The clamping portion 32s is structured so that the lead 21 fits into a groove having the substantially parallel ends 32L1 and 32L2.

[0054] Width L of the groove of clamping portion 32s, that is, the distance between end 32L1 and end 32L2, is narrower than the diameter of lead 21. In addition, the length between end 32L1 and end 32L2 is equal to or greater than the radius of the lead.

[0055] The clamping portion 32s has a groove shape with at least one end open. The width L of the groove of the clamping portion 32s is narrower than the diameter of the lead 21. Therefore, the lead 21, which is thicker than the width L of the groove of the clamping portion 32s, is forcibly pushed into the clamping portion 32s, causing slight distortion. If the pen holder 30 is made of resin, for example, a force that attempts to return the lead 21 to its original shape when it is pushed into the clamping portion 32s due to the elasticity of the resin acts in the direction of vector V1 from the contact point CP1 and in the direction of vector V2 from the contact point CP2.

[0056] The vectors V1 and V2 face each other from the contact points CP1 and CP2 toward the center Cr1 of the lead. The force acts in the directions of the vectors V1 and V2, allowing the clamping portion 32s to grip the lead 21.

[0057] In order to generate distortion when the lead 21 is pressed into the clamping portion 32s, it is desirable that at least one of the ends has an open groove shape.

[0058] The lead puller 32z of the pen holder of the reference example is a groove shaped like a V. The lead puller 32z is generally not suitable for gripping something because the vectors Vz1 and Vz2 that point from the contact points CPz1 and CPz2 of the lead 21Z and the lead puller 32z toward the center Crz1 of the lead do not oppose each other.

[0059] The reason why the lead can be pulled out by the approximately V-shaped groove pull-out structure is because the lead pull-out portion 32z is made of a material that is harder than the lead 21 and can bite into the lead. For example, if the V-shape is made of metal and the edges of the V-shaped groove are sharp, it will be possible to push the lead into the groove and have it bite into the groove, making it possible to grasp the lead.

[0060] However, if the lead puller 32z were made of metal, it would be made of a different material from the pen holder, making it impossible to mold them as one piece, resulting in a high part cost. Also, it is not preferable from the viewpoint of recyclability, since different materials would have to be bonded or pressed together.

[0061] It should be noted that the Y-axis direction is an example of a first direction, and the X-axis direction is an example of a second direction.

[0062] <Actions and Effects> The information display system 1 according to this embodiment has a pen holder 30 for an electronic pen that is carried along with the information display device 10 when the information display device 10 is used, and has a core puller 32. The pen holder 30 according to this embodiment has the core puller 32, so that the user can pull out the core (pen tip) of the electronic pen and replace it whenever the user wants to replace the core (pen tip).

[0063] Furthermore, according to the pen holder 30 of this embodiment, the lead puller 32 can sufficiently clamp the lead of the electronic pen with a clamping portion having a first end and a second end that extend linearly in a first direction. The pen holder 30 can pull out the lead of the electronic pen by sufficiently clamping the lead of the electronic pen with the clamping portion.

[0064] Furthermore, according to the pen holder 30 of this embodiment, since the pen holder 30 is formed integrally with the lead puller 32, it can be manufactured inexpensively.

[0065] Furthermore, since the pen holder 30 of this embodiment has a storage section for replacement nibs, when the user wishes to replace the nib (pen tip) of the electronic pen, the user can replace the nib by pulling out the nib (pen tip) and attaching the replacement nib stored in the storage section for the nib.

[0066] The conventional method for replacing the pen tip involves packaging a tool (e.g., Figure 6) for removing the tip from the electronic pen along with a replacement tip, and the user would typically use the tool to pinch the pen tip, pull it out, and then insert the replacement tip.

[0067] When using a jig to remove the lead, the jig and replacement leads are included with the product, so there is a risk that they will be lost if not managed carefully. Also, when using a jig to remove the lead, in the case of a portable device, there is the problem that the lead cannot be replaced even if you want to at your destination (the jig or replacement leads are not on hand). Furthermore, there is the problem that the unit price of the product increases because a dedicated jig is included with the product.

[0068] According to the pen holder 30 of this embodiment, since the pen holder 30 is provided with a lead puller and a replacement lead storage section, the user can replace the lead (pen tip) of the electronic pen whenever desired. Also, according to the pen holder 30 of this embodiment, a pen holder that allows the user to replace the lead (pen tip) of the electronic pen whenever desired can be provided at low cost.

[0069] The present invention is not limited to the configurations shown here, such as combinations of the configurations and other elements in the above-mentioned embodiments, etc. These points can be changed without departing from the spirit of the present invention, and can be appropriately determined according to the application form.
