Description

本考案は、シャフト装置に関し、より詳しくは、ダンピング効果を有するシャフト装置に関する。 The present invention relates to a shaft device, and more particularly to a shaft device having a damping effect.

プリンター、スキャナー、複写機及びファックス等のオフィス設備は広く応用されており、プリンター、スキャナー、複写機及びファックスは一般的にシャフト装置及びダンパー装置を有する。ダンパー装置を備えるシャフト装置は一般的に２種類あり、１つはプラスチック製シャフト装置である。プラスチック製シャフト装置は一般的に内部にばねが装設されるが、プラスチック部材自身の強度の限界のためにダンパー装置をプラスチック部材に内設できず、ダンパー装置を設置させるための空間を別途設計する必要があった。一般的には低級機種に応用される。もう１種類は鉄製シャフト装置である。鉄製シャフト装置の構造本体には鉄部材が使用され、リベットにより固定される。構造全体の強度が高く、鉄部材はプラスチック製シャフト装置よりも大きな内部空間が設計され、鉄製シャフト装置内部にダンパー装置を増設可能である。このため、空間を別途設計せずともよく、鉄製シャフト装置は低級機種及び高級機種に応用可能となるが、但し、高価で、体積も大きく、重量も重かった。 Office equipment such as printers, scanners, copiers and fax machines are widely applied, and printers, scanners, copiers and fax machines generally have a shaft device and a damper device. There are generally two types of shaft devices provided with a damper device, and one is a plastic shaft device. A plastic shaft device is generally equipped with a spring, but due to the strength limit of the plastic member itself, the damper device cannot be installed inside the plastic member, and a space for installing the damper device is separately designed. There was a need to do. Generally applied to low-end models. The other type is an iron shaft device. An iron member is used for the structural main body of the iron shaft device and is fixed by rivets. The strength of the entire structure is high, and the iron member is designed with a larger internal space than the plastic shaft device, and a damper device can be added inside the iron shaft device. For this reason, it is not necessary to design the space separately, and the iron shaft device can be applied to a low-end model and a high-end model, but it is expensive, large in volume, and heavy.

しかしながら、前述した従来の技術では、別途空間を設計する必要があり、高価格で、体積が大きく重い。 However, in the conventional technique described above, it is necessary to design a separate space, which is expensive, large in volume and heavy.

かかる従来の実情に鑑みて、本考案は、ダンピング効果を有するシャフト装置を提供することを目的とする。 In view of such a conventional situation, an object of the present invention is to provide a shaft device having a damping effect.

上述した課題を解決し、目的を達成するために、本考案に係るシャフト装置は、機体を含むスキャナーに応用される。前記シャフト装置は第一固持部材と、ピボット部材と、弾性押圧モジュールと、第二固持部材と、ダンパーモジュールと、第一支持部材とを更に備える。ピボット部材は第一固持部材に枢着され、ピボット部材は第一固持部材に対して第一位置、第二位置及び第三位置まで回転を行う。弾性押圧モジュールは第一固持部材内に固持されるように収容され、弾性押圧モジュールはピボット部材を弾性により押圧し、ピボット部材が第一固持部材との相対的な位置を保持させるようにする。第二固持部材は機体とピボット部材との間に固定されるように装設され、第二固持部材には上下に貫通される収容溝が開設される。ダンパーモジュールは収容溝内に収容され、ダンパーモジュールはダンパーと、ダンパー固持部材と、弾性部材とを具備する。ダンパーは固定部及び接触部を有し、固定部はダンパー固持部材に固定されるように装設され、接触部は弾性により上下に押圧する。ダンパー固持部材の頂端は第二固持部材に枢着され、弾性部材の一端は第二固持部材に固持され、他端はダンパー固持部材の頂端の一側に固持される。第一支持部材は第一固持部材に固持される。機体によりピボット部材が連動されて第一位置から第二位置まで回転を行うと、第一支持部材が接触部に未接触となって押圧されず、ダンピング効果を有さず、ダンパー固持部材により固定部が連動されると弾性部材の弾性作用により固定されて動かなくなる。機体によりピボット部材が連動されて第二位置から第三位置まで回転を行うと、第一支持部材が接触部に持続的に接触して押圧され、ダンピング効果を有し、ダンパー固持部材により固定部が連動されると弾性部材の弾性作用及び第一支持部材の押圧作用により収容溝内で擺動を行う。 In order to solve the above-described problems and achieve the object, the shaft device according to the present invention is applied to a scanner including an airframe. The shaft device further includes a first holding member, a pivot member, an elastic pressing module, a second holding member, a damper module, and a first support member. The pivot member is pivotally attached to the first holding member, and the pivot member rotates to the first position, the second position, and the third position with respect to the first holding member. The elastic pressing module is accommodated so as to be held in the first holding member, and the elastic pressing module presses the pivot member by elasticity so that the pivot member maintains a relative position with respect to the first holding member. The second holding member is installed so as to be fixed between the airframe and the pivot member, and the second holding member is provided with a receiving groove penetrating vertically. The damper module is housed in the housing groove, and the damper module includes a damper, a damper holding member, and an elastic member. The damper has a fixing portion and a contact portion, and the fixing portion is installed so as to be fixed to the damper holding member, and the contact portion presses up and down by elasticity. The top end of the damper holding member is pivotally attached to the second holding member, one end of the elastic member is fixed to the second holding member, and the other end is fixed to one side of the top end of the damper holding member. The first support member is fixed to the first holding member. When the pivot member is interlocked by the machine body and rotated from the first position to the second position, the first support member is not pressed against the contact portion and is not pressed, has no damping effect, and is fixed by the damper holding member. When the parts are interlocked, they are fixed by the elastic action of the elastic member and do not move. When the pivot member is interlocked by the machine body and rotated from the second position to the third position, the first support member is continuously pressed against the contact portion and has a damping effect, and is fixed by the damper holding member. When the two are interlocked with each other, the elastic member and the first supporting member are pressed to move in the receiving groove.

上述したように、本考案のシャフト装置は、機体の開閉過程において、ピボット部材が第一位置から第二位置まで、或いは第二位置から第一位置まで回転を行う際に、第一支持部材の係合接触部が接触部に未接触となって押圧されず、ダンピング効果が発生しない。ピボット部材が第二位置から第三位置まで、或いは第三位置から第二位置まで回転を行う際に、第一支持部材の係合接触部が接触部に持続的に接触して押圧され、ダンピング効果が発生する。これにより、本考案に係るシャフト装置は、構造内部にダンパー装置が増設されることにより空間が節約され、製造コストも低下する。 As described above, when the pivot member rotates from the first position to the second position or from the second position to the first position in the opening / closing process of the airframe, The engaging contact portion is not pressed against the contact portion and is not pressed, and a damping effect does not occur. When the pivot member rotates from the second position to the third position, or from the third position to the second position, the engagement contact portion of the first support member is continuously pressed against the contact portion and pressed. An effect occurs. As a result, the shaft device according to the present invention saves space and reduces manufacturing cost by adding a damper device inside the structure.

図２を参照し、前記第一支持部材６０は第一固持部材１０に固持される。具体的には、本実施形態では、第一支持部材６０は金属部材であり、第一支持部材６０はベース６１を有し、ベース６１の両側から後ろ向きに湾曲されて延伸された後に上向きに湾曲されて延伸される延伸部６２及びベース６１の上端縁から後向きに湾曲されて延伸される係合接触部６３が形成される。ベース６１及び延伸部６２はねじにより第一固定溝１４内に固持されるように収容され、係合接触部６３は第二固定溝１５内に係合されるように収容される。 Referring to FIG. 2, the first support member 60 is fixed to the first fixing member 10. Specifically, in the present embodiment, the first support member 60 is a metal member, and the first support member 60 has a base 61, and is bent upward and curved upward from both sides of the base 61. Then, the extending contact portion 62 and the extending contact portion 63 that are bent and extended backward from the upper end edge of the base 61 are formed. The base 61 and the extending part 62 are accommodated so as to be fixed in the first fixing groove 14 by screws, and the engagement contact part 63 is accommodated so as to be engaged in the second fixing groove 15.

なお、図７乃至図９に示されるように、機体によりピボット部材２０が連動されて第一位置から第二位置まで回転を行うと、第一支持部材６０が接触部５１２に未接触となって押圧されず、ダンピング効果を有さず、ダンパー固持部材５２により固定部５１１が連動されると弾性部材５３の弾性作用により固定されて動かなくなる。機体によりピボット部材２０が連動されて第二位置から第三位置まで回転を行うと、第一支持部材６０が接触部５１２に持続的に接触して押圧され、ダンピング効果を有し、ダンパー固持部材５２により固定部５１１が連動されると弾性部材５３の弾性作用及び第一支持部材６０の押圧作用により収容溝４１内で擺動を行う。具体的には、機体が回転して開かれることによりピボット部材２０が連動されて第一位置まで回転を行う際に（図７参照）、第一支持部材６０の係合接触部６３が接触部５１２に未接触となって押圧されず、弾性部材５３の弾性によりダンパー固持部材５２が引っ張られることでダンパー５１の接触部５１２が連動されて第四位置まで擺動を行う。この際に、ダンパー５１が後退溝２１４の一端まで擺動を行い、ストッパー２１２が接触部５１２の係止溝５１３内に止着される。ピボット部材２０が第一位置と第二位置との間まで回転を行うと、第一支持部材６０の係合接触部６３が依然として接触部５１２に未接触となって押圧されない。ピボット部材２０が第二位置まで回転を行うと（図８参照）、第一支持部材６０の係合接触部６３が接触部５１２に接触して押圧される。ピボット部材２０が第二位置から第三位置に向けて回転を行う場合、第一支持部材６０の係合接触部６３が接触部５１２に接触して押圧されることで弾性によって上に移動させられ、同時に、ダンパー５１が後退溝２１３の一端から他端まで小幅に擺動を行う。ピボット部材２０が第三位置まで回転を行うと（図９参照）、機体が閉まった状態となり、第一支持部材６０の係合接触部６３が接触部５１２に接触して押圧され、ダンパー５１が第五位置まで擺動を行う。この際、第一支持部材６０の係合接触部６３がピボット部材２０の開放溝２１１の両側の溝壁の下表面に当接され、ストッパー２１２が接触部５１２の係止溝５１３から脱離される。 As shown in FIGS. 7 to 9, when the pivot member 20 is interlocked by the machine body and rotated from the first position to the second position, the first support member 60 is not in contact with the contact portion 512. When the fixing portion 511 is interlocked by the damper holding member 52, it is fixed by the elastic action of the elastic member 53 and does not move. When the pivot member 20 is interlocked by the machine body and rotated from the second position to the third position, the first support member 60 is continuously contacted with the contact portion 512 and pressed, and has a damping effect. When the fixed portion 511 is interlocked by 52, the elastic member 53 is oscillated and the first support member 60 is pressed in the accommodation groove 41. Specifically, when the pivoting member 20 is interlocked and rotated to the first position by rotating and opening the airframe (see FIG. 7), the engagement contact portion 63 of the first support member 60 is the contact portion. The damper holding member 52 is pulled by the elasticity of the elastic member 53 without being pressed against the 512, and the contact portion 512 of the damper 51 is interlocked to swing to the fourth position. At this time, the damper 51 swings to one end of the receding groove 214, and the stopper 212 is fixed in the locking groove 513 of the contact portion 512. When the pivot member 20 rotates between the first position and the second position, the engagement contact portion 63 of the first support member 60 is still not in contact with the contact portion 512 and is not pressed. When the pivot member 20 rotates to the second position (see FIG. 8), the engagement contact portion 63 of the first support member 60 comes into contact with the contact portion 512 and is pressed. When the pivot member 20 rotates from the second position to the third position, the engagement contact portion 63 of the first support member 60 is moved upward by elasticity by being pressed against the contact portion 512. At the same time, the damper 51 swings from one end to the other end of the receding groove 213 with a small width. When the pivot member 20 rotates to the third position (see FIG. 9), the airframe is in a closed state, the engagement contact portion 63 of the first support member 60 is pressed against the contact portion 512, and the damper 51 is pressed. Move to fifth position. At this time, the engagement contact portion 63 of the first support member 60 is brought into contact with the lower surface of the groove wall on both sides of the opening groove 211 of the pivot member 20, and the stopper 212 is detached from the locking groove 513 of the contact portion 512. .

In the present embodiment, the second support member 70 is a metal member, and the second support member 70 is accommodated so as to be fixed in the accommodation groove 11 of the first holding member 10. Specifically, the second support member 70 includes two side plates 72 formed so as to be curved and extended toward the rear upper side after being bent and extended upward from both sides of the substrate 71 and the substrate 71. The substrate 71 is provided with an engagement hole 711, and an engagement hook portion 712 that is curved and extended downward is formed on the front edge and the rear edge of the substrate 71. The boss 17 is engaged in the engagement hole 711, the two engagement hook portions 712 are respectively engaged with the front surface and the rear surface of the convex plate 16, and the upper ends of the two side plates 72 are screwed to the first holding member. 10 and the first support member 60. The structural strength of the entire shaft device 100 is enhanced by the design of the first support member 60 and the second support member 70.

次は、図７乃至図９に示されるように、本考案に係るシャフト装置１００の作動時に、機体が完全に開かれた状態になると、第二固持部材４０により機体とピボット部材２０との間に固定されるように装設され、機体によりピボット部材２０が連動されて第一位置まで回転を行うと（図７参照）、第一支持部材６０の係合接触部６３が接触部５１２に未接触となって押圧されず、弾性部材５３の弾性によりダンパー固持部材５２が引っ張られることによりダンパー５１の接触部５１２が連動されて第四位置まで擺動を行う。この際、ダンパー５１が後退溝２１４の一端まで擺動を行い、ストッパー２１２が接触部５１２の係止溝５１３内に止着され、ダンピング効果が発生する。機体が閉められると、ピボット部材２０が回転を継続させ、第二位置まで回転を行うと（図８参照）、第一支持部材６０の係合接触部６３が接触部５１２に接触して押圧を開始させる。この際、ダンピング効果が生じ始める。ピボット部材２０が第三位置まで回転を行うと（図９参照）、第一支持部材６０の係合接触部６３が接触部５１２に接触して押圧されることで弾性により上に移動させられ、同時に、ダンパー５１が後退溝２１４の一端から他端に向けて第五位置まで小幅に擺動を行い、第一支持部材６０の係合接触部６３がピボット部材２０の開放溝２１１の両側の溝壁の下表面に当接され、ストッパー２１２が接触部５１２の係止溝５１３から脱離される。この際、機体が閉められた状態となり、ダンピング効果が発生する。機体が再度開かれると、ピボット部材２０が第三位置から第二位置まで回転を行い（図８参照）、第一支持部材６０の係合接触部６３が接触部５１２に接触して押圧され、ダンピング効果が発生する。ピボット部材２０が第二位置から第一位置まで回転を行うと（図７参照）、第一支持部材６０の係合接触部６３が接触部５１２から脱離され、接触部５１２が元の位置に戻され、固定部５１１が弾性部材５３の弾性引張作用により元の位置に戻され、ダンピング効果が発生しなくなる。 Next, as shown in FIGS. 7 to 9, when the airframe is completely opened during the operation of the shaft device 100 according to the present invention, the second holding member 40 causes the airframe to pivot between the airframe and the pivot member 20. When the pivot member 20 is interlocked and rotated to the first position by the machine body (see FIG. 7), the engagement contact portion 63 of the first support member 60 is not connected to the contact portion 512. When the damper holding member 52 is pulled by the elasticity of the elastic member 53 without being pressed and brought into contact, the contact portion 512 of the damper 51 is interlocked to swing to the fourth position. At this time, the damper 51 swings to one end of the receding groove 214, and the stopper 212 is fixed in the locking groove 513 of the contact portion 512, and a damping effect is generated. When the airframe is closed, the pivot member 20 continues to rotate and rotates to the second position (see FIG. 8), and the engagement contact portion 63 of the first support member 60 comes into contact with the contact portion 512 and presses it. Let it begin. At this time, a damping effect starts to occur. When the pivot member 20 is rotated to the third position (see FIG. 9), the engagement contact portion 63 of the first support member 60 is moved in contact with the contact portion 512 and pressed upward by elasticity, At the same time, the damper 51 swings from the one end to the other end of the receding groove 214 with a small width to the fifth position, and the engagement contact portions 63 of the first support member 60 are groove walls on both sides of the opening groove 211 of the pivot member 20. The stopper 212 is detached from the locking groove 513 of the contact portion 512. At this time, the airframe is closed and a damping effect is generated. When the airframe is opened again, the pivot member 20 rotates from the third position to the second position (see FIG. 8), and the engagement contact portion 63 of the first support member 60 comes into contact with the contact portion 512 and is pressed. Damping effect occurs. When the pivot member 20 rotates from the second position to the first position (see FIG. 7), the engagement contact portion 63 of the first support member 60 is detached from the contact portion 512, and the contact portion 512 returns to the original position. The fixed portion 511 is returned to the original position by the elastic tension action of the elastic member 53, and the damping effect is not generated.

上述したように、本考案のシャフト装置１００は、機体の開閉過程において、ピボット部材２０が第一位置から第二位置まで、或いは第二位置から第一位置まで回転を行うと、第一支持部材６０の係合接触部６３が接触部５１２に未接触となって押圧されず、ダンピング効果が発生しない。ピボット部材２０が第二位置から第三位置まで、或いは第三位置から第二位置まで回転を行うと、第一支持部材６０の係合接触部６３が接触部５１２に持続的に接触して押圧され、ダンピング効果が発生する。よって、本考案に係るシャフト装置１００は、構造内部にダンパー装置が増設されるため空間が節約され、製造コストも低下する。また、第一支持部材６０及び第二支持部材７０の設計によりシャフト装置１００全体の構造強度が強化される。 As described above, when the pivot member 20 rotates from the first position to the second position or from the second position to the first position in the process of opening and closing the airframe, the shaft device 100 of the present invention has the first support member. The 60 engagement contact parts 63 are not pressed against the contact part 512 and are not pressed, and a damping effect does not occur. When the pivot member 20 rotates from the second position to the third position or from the third position to the second position, the engagement contact portion 63 of the first support member 60 continuously contacts and presses the contact portion 512. And a damping effect occurs. Therefore, the shaft device 100 according to the present invention has an additional damper device inside the structure, so that space is saved and the manufacturing cost is reduced. Further, the structural strength of the entire shaft device 100 is enhanced by the design of the first support member 60 and the second support member 70.
