[0007] Technical problem to be solved by the invention

[0008] Therefore, in the mouse, if the detection shafts or ball bearings supporting the balls fail or wear out, new ones must be purchased, which is cost-effective.

[0009] The object of the present invention is to provide a mouse and a replacement supporting tool set with high cost performance.

[0010] Solutions for solving technical problems

[0011] The mouse of the present invention comprises: a spherical ball; a mouse body having a housing portion capable of housing the ball in a freely rolling manner, the housing portion having: a housing recess opening outward and recessed inwardly so as to be capable of housing the ball inside; and a supporting component provided in the housing recess for supporting the ball housed in the housing recess, the supporting component being configured to be attachable and detachable relative to the housing recess.

[0012] According to this structure, since a failed or worn supporting member can be replaced with a new supporting member, there is no need to buy a new mouse even if the supporting member fails or is worn, and the cost performance is high.

[0013] In addition, in the mouse, it can also be configured that the accommodating recess has a supporting mounting portion, the supporting mounting portion has the supporting component mounted in a detachable manner, and the supporting component has: a base that can be detachably mounted relative to the supporting mounting portion; and a supporting portion that is provided on the base and supports the sphere accommodated in the accommodating recess.

[0014] According to this configuration, since the support member can be replaced as a unit including the base portion and the support portion, the support member can be easily replaced.

[0015] In addition, in the mouse, it can also be configured that the support mounting portion includes a mounting recess recessed in the accommodating recess, and the support component can be installed and removed relative to the support mounting portion by inserting the base into the mounting recess or pulling it out from the mounting recess.

[0016] According to this configuration, the support member can be easily replaced by simply removing the failed or worn support member from the mounting recess and inserting a new support member into the mounting recess.

[0017] The replacement support tool set of the present invention is used for a mouse, which is configured to perform input operations on a computer and comprises: a mouse body having a receiving recessed portion recessed inwardly; a spherical ball received in the receiving recess in a freely rolling manner, and the replacement support tool set includes a support component, which is configured to be installable and removable relative to the interior of the receiving recess and to support the received ball.

[0018] According to this configuration, a failed or worn support member can be replaced simply by purchasing a replacement support tool set, and thus the mouse has high cost performance.

[0019] In addition, the replacement support tool set may further include an installation and removal fixture, which is used to engage with the support member installed in the receiving recess, so as to remove the support member from the receiving recess.

[0020] According to this configuration, the support member can be easily attached and detached and replaced using an attachment and detachment jig.

[0044] The roller 32 is a roller corresponding to a rolling operation. In addition, the roller 32 is formed in a disk shape. Moreover, the roller 32 is freely rotatable around the axis, and a part of it protrudes from the upper part 301 of the housing.

[0045] Two browsing operation keys 33 are arranged side by side in front and back (on the side farther from the user and on the side closer to the user) on the left side edge of the main operation key 31 located on the left side. The browsing operation key 33 located on the front side is a key for advancing the browsing history to the newer side (corresponding to the "forward" of the web browser). The browsing operation key 33 located on the rear side is a key for returning to the browsing history to the older side (corresponding to the "back" of the web browser).

[0046] The speed setting key 34 is a key for setting the speed of the pointer cursor on the display. In the present embodiment, the speed setting key 34 is an operation piece that can be switched among three speed setting selection positions: low speed, medium speed, and high speed.

[0047] The power switch 35 is a switch for switching the power of the mouse 1 on and off.

[0048] The sensor unit 36 ​​includes an optical sensor for detecting the rotation amount of the sphere 4 , a lens, a sensor substrate, etc. The sensor substrate of the sensor unit 36 ​​is electrically connected to the circuit board 37 .

[0049] The circuit board 37 outputs a signal to the computer so that the pointer cursor on the display moves according to the rotation amount of the sphere 4 detected by the sensor unit 36 ​​.

[0050] The housing 2 supports the sphere 4 so that it can rotate freely while a part of the sphere 4 is exposed. Figure 3 As shown, the receiving portion 2 has: a receiving recess 5 which is open to the outside and is recessed inwardly in a manner that the ball 4 can be received inside; and a supporting member 6 which is provided in the receiving recess 5 and supports the ball 4 received in the receiving recess 5. The mouse 1 has three supporting members 6. In addition, the mouse 1 may have only one supporting member 6, or only two supporting members 6, or may have more than four supporting members 6.

[0051] The receiving recess 5 is a substantially hemispherical body for mounting the spherical body 4. Figure 1 The sensor unit 36 ​​shown. The diameter of the housing recess 5 is larger than the diameter of the spherical body 4. In the present embodiment, the housing recess 5 is arranged so that the inner surface 52 of the housing recess 5 is inclined downward toward the left side and toward the front (close to the user).

[0052] The receiving recess 5 has a support mounting portion 50 to which the support member 6 is detachably mounted. The receiving recess 5 also has a concave surface portion 51 that covers a portion of the spherical body 4 from the bottom side. The various structures of the receiving recess 5 will be described later.

[0053] The supporting member 6 is configured to be attachable and detachable relative to the receiving recess 5. Fig.11As shown, the support member 6 can be attached and detached relative to the receiving recess 5 using an attachment and detachment jig 7. The attachment and detachment jig 7 is, for example, a pair of tweezers that clamp the support member 6 from both sides. In addition, the support member 6 can also be installed in the receiving recess 5 by the user's fingers.

[0054] The attachment and detachment jig 7 includes, for example, a gripping portion 70 gripped by a user's fingers; a pair of first extension portions 71 extending from the gripping portion 70; and a pair of second extension portions 72 extending from the extension ends of the pair of first extension portions 71. Each first extension portion 71 is bent at a position in the middle of the extension direction, but can also extend in a straight line. The pair of second extension portions 72 extend in a direction approaching each other. In addition, the front end portion of each second extension portion 72 is formed into a front end thinner than the base end portion.

[0055] In this embodiment, the support member 6 includes: a base 60 that can be attached and detached relative to the support mounting portion 50; a support portion 61 provided on the base 60 and supporting the ball 4 accommodated in the accommodation recess 5 (see Figure 4 ). The support member 6 is formed by assembling a base 60 and a support portion 61 which are manufactured separately. In addition, in the support member 6, the support portion 61 is fixed to the base 60, and the user cannot remove the support portion 61 from the base 60. In addition, the base 60 and the support portion 61 may be formed by integral molding (for example, integral resin molding).

[0056] The support portion 61 supports the spherical body 4 by contacting the spherical body 4 (see Figure 3 ). In the present embodiment, the three support portions 61 support the spherical body 4 by contacting the spherical body 4. In addition, the support portions 61 protrude inward from the inner surface 52 of the housing recess 5.

[0057] The support part 61 is a spherical body or a cylindrical body. As the spherical body, an artificial ruby ​​ball or a ceramic ball or the like is used. In addition, the spherical body can be fixed in a rolling manner relative to the base 60, or can be fixed in a non-rolling manner relative to the base 60. As the cylindrical body, a bearing or a roller or the like can be used. In addition, the cylindrical body is fixed in a rolling manner relative to the base 60.

[0058] For example, the support part 61 includes: an artificial ruby ​​ball 61A that is a non-rolling spherical body fixed in a non-rolling manner relative to the base 60; and a bearing 61B that is a rolling cylindrical body fixed in a rolling manner relative to the base 60. In the present embodiment, the support part 61 includes two different support parts 61A and 61B, but may also include three or more support parts, or only one support part. In the mouse 1, two artificial ruby ​​balls 61A and one bearing 61B support the ball 4.

[0059] The base 60 supports the support portion 61 and is mounted on the support mounting portion 50. In addition, the base 60 includes: a first base 60A supporting the artificial ruby ​​ball 61A; and a second base 60B supporting the bearing 61B. Figure 5 and Figure 6 As shown, most of the base 60 is located outside the inner surface 52 of the receiving recess 5 .

[0060] like Figure 7 (a) and Figure 7 As shown in (b), the first base 60A includes: a loading portion 600A on which the artificial ruby ​​ball 61A is loaded; and a first pedestal portion 601A supporting the loading portion 600A. The loading portion 600A includes: an annular ring portion 602A on which the artificial ruby ​​ball 61A is loaded; and a pair of loading legs 603A extending from two locations sandwiching the center point of the periphery of the annular portion 602A. Figure 7 (b) and Figure 7 As shown in (c), the first pedestal portion 601A includes: a quadrilateral plate portion 604A whose central portion is recessed in a manner to place the annular portion 602A; and four first pedestal legs 605A extending from the four corners of the plate portion 604A. A pair of through holes 606A (see Figure 7 (a)). Figure 8 As shown, by inserting each of the loading legs 603A of the loading portion 600A into each of the through holes 606A of the first pedestal portion 601A, the loading portion 600A is fixed to the first pedestal portion 601A. In this embodiment, the portion of the base 60 other than the annular portion 602A is located outside the inner surface 52 of the receiving recess 5 (see Figure 5 and Figure 6 ).

[0061] like Fig. 9 (a) and Fig. 9 As shown in (b), the second base portion 60B includes: a shaft portion 600B equipped with a bearing 61B; and a second pedestal portion 601B supporting the shaft portion 600B. The second pedestal portion 601B includes: a quadrilateral annular frame portion 602B; and a pair of shaft connecting portions 603B provided on two opposing sides of one of two sets of opposing sides of the frame portion 602B and connected to the shaft portion 600B. In addition, the second pedestal portion 601B includes a pair of second pedestal support legs 604B extending from the other opposing sides of the frame portion 602B. Fig. 9 (c) and Fig.10 As shown, the shaft portion 600B is connected to the shaft connection portion 603B of the second seat portion 601B, whereby the shaft portion 600B is fixed to the second seat portion 601B.

[0062] The concave surface 51 of the receiving concave portion 5 has the function of hiding the circuit board 37 and the battery B when the user removes the ball 4 from the receiving concave portion 5 (see Figure 3 ). In this embodiment, the concave portion 51 is provided with a Figure 1 The sensor unit 36 ​​is shown in the opening 510. Figure 1 A recessed portion extrusion hole 511 is provided at a position overlapping the housing extrusion hole 303. The inner surface of the recessed portion 51 is a recessed surface 512 corresponding to a hemispherical shape.

[0063] One support member 6 is mounted on each support mounting portion 50. In the present embodiment, three support mounting portions 50 are provided. The three support mounting portions 50 are arranged in a ring shape on the concave surface 512 of the concave portion 51. In addition, the three support mounting portions 50 are arranged at equal intervals from each other in the arrangement direction of the support mounting portions 50.

[0064] like Figure 4 As shown, each support mounting portion 50 includes a mounting recess 500 recessed in the receiving recess 5. In addition, the support mounting portion 50 includes a locking portion 501 that is locked with the support member 6 installed in the mounting recess 500. In addition, the support mounting portion 50 has an insertion hole 502, which is provided when the support member 6 is installed and removed from the mounting recess 500. Fig.11 The assembly and disassembly fixture 7 shown is inserted.

[0065] The mounting recess 500 is a portion into which the base 60 of the support member 6 is inserted. The mounting recess 500 is a recess that is recessed in the thickness direction of the recessed surface 51 in the recessed surface 51. In the present embodiment, the mounting recess 500 is a quadrilateral recess when viewed from the thickness direction of the recessed surface 51. In addition, the shape of the mounting recess 500 when viewed from the thickness direction of the recessed surface 51 may be any shape as long as it corresponds to the shape of the base 60 of the support member 6.

[0066] The locking portion 501 is a locking piece that presses the base portion 60 inserted into the mounting recess 500 from the inner side of the recessed surface portion 51. The locking portion 501 is locked with the end portion of the base portion 60 of the support member 6.

[0067] In this embodiment, if Figure 5 As shown in FIG. 1 , a pair of locking portions 501 are provided in a manner of being locked at one end and the other end of the base 60 of the support member 6. That is, the support member 6 has a pair of locked portions locked with the locking portion 501 at one end and the other end of the base 60. Specifically, the locking portion 501 is locked with one end and the other end of the plate portion 604A of the support member 6A, respectively. That is, the support member 6A has a pair of locked portions locked with the locking portion 501 at both ends of the plate portion 604.

[0068] In addition, the supporting member 6B is also similar to the supporting member 6A, and the locking portion 501 is respectively locked at one end and the other end of the frame portion 602B of the base 60B of the supporting member 6B. That is, the supporting member 6B has a pair of locked portions locked with the locking portion 501 at one end and the other end of the frame portion 602B.

[0069] The pair of locking portions 501 are arranged so as to sandwich the mounting recess 500. Specifically, the pair of locking portions 501 extend from opposing positions in the periphery of the mounting recess 500 to a position closer to the front than the support portion 61 in the mounting recess 500. The material and thickness of the locking portions 501 are formed to be able to bend due to the force when the user pulls the support member 6 out of the mounting recess 500 or the force when the user inserts the support member 6 into the mounting recess 500.

[0070] The insertion hole 502 is provided continuously with the mounting recess 500. In addition, a pair of insertion holes 502 is provided so that a pair of first extension portions 71 and second extension portions 72 of the tweezers 7 as the mounting and disassembly jig 7 are inserted therein, and the inserted portion of the tweezers 7 is locked to the base 60 of the support member 6 (see Figure 4 ). That is, the support member 6 has a pair of locked portions at one end and the other end of the base 60, which are locked with the portion of the tweezers 7 inserted into the insertion hole 502. Specifically, the portion of the tweezers 7 inserted into the insertion hole 502 is respectively locked at one end and the other end of the plate portion 604A of the support member 6A on the side where the locking portion 501 is not locked. That is, the support member 6A has a pair of locked portions at one end and the other end on the side where the locking portion 501 is not locked in the plate portion 604, which are locked with the portion of the tweezers 7 inserted into the insertion hole 502.

[0071] In addition, as with the support member 6B, the locking portion 501 is locked to one end and the other end of the frame portion 602B of the base 60B of the support member 6B, respectively, on the side where the locking portion 501 is not locked. That is, the support member 6B has a pair of locked portions that are locked to the part of the forceps 7 inserted into the insertion hole 502 at one end and the other end of the frame portion 602B on the side where the locking portion 501 is not locked.

[0072] The pair of insertion holes 502 are arranged in a manner of clamping the mounting recess 500. Specifically, the pair of insertion holes 502 extend from the opposing position of the periphery of the mounting recess 500 where the locking portion 501 is not provided in a direction away from the mounting recess 500. In the present embodiment, the pair of insertion holes 502 are arranged in a pair in the arrangement direction of the support mounting portion 50 in a manner of clamping the mounting recess 500, but the pair of insertion holes 502 may be arranged in a pair in a direction different from the arrangement direction of the support mounting portion 50 in a manner of clamping the mounting recess 500. The size of the insertion hole 502 is formed so that the pair of first extension portions 71 and second extension portions 72 of the tweezers 7 can be inserted.

[0073] The insertion hole 502 is partially provided between the peripheral surface of the base 60 of the support member 6 and a portion of the concave surface 51 that faces the peripheral surface of the base 60. Figure 6 As shown, a gap S into which the attachment and detachment jig 7 can be inserted is provided between the base 60 and the support mounting portion 50, continuously with the insertion hole 502. Specifically, the gap S continuously extends between the pair of insertion holes 502. In addition, the gap S is arranged outside the portion located outside the base 60 of the support member 6 (for example, the first pedestal leg portion 605A or the second pedestal leg portion 604B).

[0074] Moreover, in this embodiment, the support member 6 can be attached to and detached from the support mounting portion 50 by inserting the base 60 into or removing it from the mounting recess 500. Hereinafter, removal of the support member 6 from the support mounting portion 50 and attachment of the support member 6 to the support mounting portion 50 will be described in order.

[0075] When the user removes the support member 6 from the support mounting portion 50, first, the user presses a finger from the bottom side of the housing 30 into the housing press-out hole 303 and the recess press-out hole 511 of the receiving recess 5, thereby squeezing out the ball 4 and removing it from the receiving recess 5 (refer to Figure 2 and Figure 3 ). When the support member 6 is mounted on the support mounting portion 50, the base 60 as the locking portion of the support member 6 is embedded in the mounting recess 500 as the locked portion of the support mounting portion 50 (refer to Fig.11 ).

[0076] Then, the user inserts the detachable jig 7 into the insertion hole 502 of the support mounting portion 50. As a result, the first extension portion 71 and the second extension portion 72 of the detachable jig 7 are arranged in the insertion hole 502. In this embodiment, the user further inserts the detachable jig 7 inserted into the insertion hole 502 into the gap S between the base 60 and the support mounting portion 50 (see Figure 6). Thus, the second extension portion 72 of the mounting and disassembling jig 7 is arranged in the gap S. At this time, the first extension portion 71 as the locking portion of the mounting and disassembling jig 7 is locked to the locked portion, that is, the peripheral surface of the base 60. In addition, the second extension portion 72 as the locking portion of the mounting and disassembling jig 7 is locked to the locked portion, that is, the bottom surface of the base 60.

[0077] By pulling the mounting and disassembling jig 7 from this state toward the inside of the receiving recess 5, the second extension portion 72 of the mounting and disassembling jig 7 hooks the bottom surface of the base 60 of the support member 6, and in this state, a force toward the inside of the receiving recess 5 acts on the support member 6. In this embodiment, since the force toward the inside acts on the support member 6, the force toward the inside is applied from the inner portion of the base 60 (for example, the plate portion 604A) to the locking portion 501 of the support mounting portion 50, and the locking portion 501 is bent inwardly, and the locking of the locking portion 501 and the base 60 of the support member 6 is released (see Figure 5 ). Thus, the user can remove the support member 6 from the support mounting portion 50.

[0078] On the other hand, when the user attaches the support member 6 to the support mounting portion 50, the user presses the base 60 of the support member 6 into the mounting recess 500 with the user's fingers. In the present embodiment, when the support member 6 is pressed into the mounting recess 500, the outer portion of the base 60 (for example, the placement leg portion 603A) contacts the locking portion 501, the locking portion 501 bends outward, and the base 60 of the support member 6 moves outward relative to the locking portion 501. In this way, the base 60 of the support member 6 moves outward, and the base 60 as the locking portion of the support member 6 is embedded in the mounting recess 500 as the locked portion of the support mounting portion 50.

[0079] According to the above mouse 1, since the failed or worn support member 6 can be replaced with a new support member 6, there is no need to repurchase the mouse 1 even if the support member 6 fails or wears out, and the cost performance is high.

[0080] In the mouse 1 of this embodiment, the support member 6 can be replaced as a unit having a base 60 and a support portion 61, so it is easy to replace the support member 6. Specifically, even when a different type of support portion 61 (for example, an artificial ruby ​​ball 61A and a bearing 61B) is replaced, it can be easily replaced as a unit (support member 6). In addition, the size of the support member 6 is larger than that of the support portion 61, so it is easier to replace the support member 6 than to replace the support portion 61 alone.

[0081] In the mouse 1 of the present embodiment, the support member 6 can be easily replaced by removing the failed or worn support member 6 from the mounting recess 500 and inserting a new support member 6 into the mounting recess 500 .

[0082] Furthermore, it is considered to sell a replacement support tool set 100 for such a mouse 1. The replacement support tool set 100 is used for the mouse 1, which is configured to perform input operations on a computer and includes: a mouse body 3 having a receiving recess 5 recessed inwardly; and a spherical ball 4 received in the receiving portion 2 in a freely rolling manner. In addition, the replacement support tool set 100 includes a support member 6, which is configured to be attachable to and detachable from the inside of the receiving recess 5 and supports the received ball 4.

[0083] Furthermore, the replacement support tool set 100 includes a mounting and disassembling fixture 7 for engaging with the support member 6 installed in the receiving recess 5, thereby removing the support member 6 from the receiving recess 5. In this embodiment, the replacement support tool set 100 includes three support members 6 and one mounting and disassembling fixture 7.

[0084] If the replacement support tool set 100 is purchased, the failed or worn support component 6 can be replaced, so there is no need to re-purchase the mouse 1 even if the support component 6 fails or is worn, and the mouse 1 has a high cost performance.

[0085] Furthermore, in the replacement support tool set 100 of the present embodiment, the support member 6 can be easily attached to and detached from the mouse 1 using the attachment and detachment jig 7 included in the replacement support tool set 100 , thereby replacing the support member 6 .

[0086] The number of the supporting components 6 included in the replacement supporting tool set 100 may be one, two, or four or more. The number of the supporting components 6 included in the replacement supporting tool set 100 may be the same as the number of the supporting components 6 installed on one mouse 1, or may be less or more than the number of the supporting components 6 installed on one mouse 1. In addition, the supporting components 6 included in the replacement supporting tool set 100 may include a plurality of different supporting components 6, or may include only one type of supporting component 6.

[0087] Furthermore, the replacement support tool set 100 may include no jig and only the support member 6. In this case, the user can remove the support member 6 from the storage recess 5 using a jig such as commercially available tweezers.

[0088] In addition, the mouse of the present invention is not limited to the above-mentioned embodiments, and various changes can be added without departing from the scope of the present invention. For example, the structure of another embodiment can be added to the structure of a certain embodiment, and a part of the structure of a certain embodiment can be replaced with the structure of another embodiment. Moreover, a part of the structure of a certain embodiment can be deleted.

[0089] In the support member 6 of the above-mentioned embodiment, the user cannot remove the support portion 61 from the base 60, but the user can also remove the support portion 61 from the base 60. In this case, the user can also replace the support portion 61 alone. For example, when the artificial ruby ​​ball 61A is worn, the user takes the support member 6 out of the receiving recess 5, and only takes out the artificial ruby ​​ball 61A from the base 60A of the taken-out support member 6 and replaces it. Then, after the user installs the new artificial ruby ​​ball 61A on the base 60A, the user can install the support member 6 in the receiving recess 5.

[0090] In the above embodiment, most of the base 60 of the support member 6 is located outside the inner surface 52 of the receiving recess 5, but the entire base 60 may be located outside the inner surface 52 of the receiving recess 5. In addition, most of the base 60 may be located inside the inner surface 52 of the receiving recess 5, or the entire base 60 may be located inside the inner surface 52.

[0091] In the above embodiment, the first base 60A of the support member 6A is composed of two parts, namely the placement portion 600A on which the artificial ruby ​​ball 61A is placed and the first seat portion 601A. However, it may be composed of one part or three or more parts.

[0092] In the above embodiment, the support member 6B includes one bearing 61B, but may include a plurality of bearings 61B. In this case, a plurality of bearings 61B may be mounted on the shaft portion 600B of the second base portion 60B. In addition, the second base portion 60B of the support member 6B is composed of two parts, namely the shaft portion 600B and the second pedestal portion 601B, but may also be composed of one part, or may be composed of three or more parts.

[0093] In the above embodiment, the support mounting portion 50 includes the mounting recess 500 into which the support member 6 is inserted. However, instead of the mounting recess 500 , a through hole into which the support member 6 is inserted may be included.

[0094] In the above embodiment, the mounting and disassembling fixture 7 is a pair of tweezers, but it can also be another fixture such as a screwdriver. When the mounting and disassembling fixture 7 is a screwdriver, for example, an insertion hole 502 supporting the mounting portion 50 can be provided in a mounting recess 500 for inserting the screwdriver.
