[0074] The assembly relationship and the effect of the embodiment according to the above configurations are described in detail based on the drawings as follows.

[0075] In the cover (100), the first frame rotation roller (110) is rotatably fastened to both sides of the keyboard body (10).

[0076] One end of the membrane rotation frame portion (120) is connected to one end of the axis that rotates each first frame rotation roller (110) so as to be capable of multi-joint rotation.

[0077] At this time, each membrane rotation frame part (120) may be provided with at least two frames connected by a rotation axis as shown in the drawing.

[0078] The other end of each membrane rotation frame (120) is rotatably connected to the front ends on both sides, and a shield (130) capable of protecting the keyboard body (10) and a plurality of keycaps (50) is provided.

[0079] At this time, it is preferable that the cover (130) be made of a transparent acrylic plate material so that even if it is placed on the upper side of the keycap (50), the operator can type on multiple keycaps (50) without difficulty from the operator's line of sight.

[0080] In particular, since the shield (130) is used in a space where a lot of foreign substances are generated, such as a construction site or a factory, due to the nature of the present invention, it has the effect of preventing foreign substances from entering the gap between the keycap (50) and the keyboard body (10) and causing the keycap (50) to break down.

[0081] Next, a second frame rotation roller (140) is rotatably fastened to the rear ends on both sides of the shield (130).

[0082] One end of a membrane support frame (150) that can rotate toward the upper surface of the keyboard body (10) is fastened to one end of an axis that rotates each of the second frame rotation rollers (140), and the other end of the membrane support frame (150) is provided so as to be rotatable toward a frame groove (10a) formed in the keyboard body (10).

[0083] The operator can place the shield (130) to cover the keyboard body (10) and multiple keycaps (50) for typing by the multi-joint rotation of the shield rotation frame (120) and the rotation of the first frame rotation roller (110), and fix the shield support frame (150) into the frame groove (10a) by the rotation of the second frame rotation roller (140) and the rotation of the shield support frame (150), thereby placing the shield (130) close to horizontal and blocking the inflow of foreign substances.

[0084] In the foreign substance removal unit (200), a pair of removal unit moving rails (210) are installed to cross the inner front and rear surfaces of the shield (130).

[0085] An upper moving roller (230) is rotatably fastened at regular intervals on the upper surface of a removal body (220) that is arranged to be movable along a removal body moving rail (210), and the upper peripheral portion protrudes from the upper surface of the removal body (220) and is arranged to be in contact with the upper inner surface of the removal body moving rail (210).

[0086] Next, the removal cylinder (250) is placed vertically based on the removal body (220), and the upper part is fixed to the center of the lower surface of the removal body (220), and the axial rotation rod (270) is inserted vertically inward from the lower part of the removal cylinder (250) and elastically supported by the removal spring (260).

[0087] At this time, the upper end of the removal spring (260) is fastened to the lower surface of the removal body (220), and the lower end is fastened to the upper end of the axial rotation rod (270).

[0088] In particular, the lower part of the removal part moving rail (210) may be further formed with a cylinder moving groove through which the removal part cylinder (250) can move without obstruction so that the removal part cylinder (250) can move along the removal part moving rail (210).

[0089] A roller rotation shaft (280) is inserted so as to be rotatable while crossing the lower end of each axis rotation rod (270).

[0090] A removal roller (290) is inserted into the circumference of the roller rotation shaft (280) so as to be rotatable as one piece with the roller rotation shaft (280), and removal members (290a) are formed at regular intervals on the circumference of the removal roller (290), so that foreign substances can be removed between a plurality of keycaps (50).

[0091] Meanwhile, the lower moving roller (240) is rotatably fastened to both lower sides of the removal unit body (220), and the lower peripheral portion of the lower moving roller (240) protrudes and is placed in contact with the lower inner surface of the removal unit moving rail (210).

[0092] By controlling the upper moving roller (230) and the lower moving roller (240), the removal body (220) moves along the removal moving rail (210), and a plurality of keycaps (50) and the removal roller (290) come into contact and rotate around the roller rotation axis (280), and the removal roller (290) is elastically pressed by the keycap (50), so that the shaft rotation rod (270) is upwardly supported by the elastic force of the removal spring (260), so that the removal roller (290) can repeatedly face the keycap (50).

[0093] Next, the belt engagement roller (300) is positioned so that a portion of it protrudes while being rotatably connected horizontally to both sides of the removal body (220).

[0094] At this time, the belt engagement roller (300) can be engaged with the removal unit drive belt (310) that is wrapped around both inner sides of the removal unit moving rail (210), and the removal unit drive gear (320) can be horizontally arranged at a certain interval to rotate the removal unit drive belt (310) and can be engaged with the removal unit drive belt (310) at the circumference of the removal unit drive gear (320).

[0095] In addition, in order to support the removal unit drive gear (320) to the removal unit moving rail (210), a gear support bracket (330) is fastened to each removal unit drive gear (320) in a 'ㅜ' shape, and each gear support bracket (330) is fixed to the upper surface of both ends of the removal unit moving rail (210).

[0096] Accordingly, the removal unit drive gear (320) rotates the removal unit drive belt (310), and the belt engagement roller (300) engaged therewith rotates along the removal unit drive belt (310) to move the removal unit body (220) along the removal unit moving rail (210).

[0097] Each roller of the foreign substance removal unit (200) is electrically connected to a motor, and each roller can rotate by the rotational force generated by the motor being operated under the operator's control.

[0098] In the moving induction unit (340), one end of the induction unit cylinder (341) is horizontally fixed to the front and rear ends of the removal unit body (220) and is arranged horizontally.

[0099] As the spring support member (342) is inserted as shown in the drawing so as to vertically penetrate each guide cylinder (341), the protruding portion can protrude outward from the guide cylinder (341) to support the spring support member (342) from the guide cylinder (341).

[0100] The induction shaft (343) is inserted horizontally into the other end of the induction cylinder (341) and penetrates the spring support member (342), and the induction spring (344) is inserted into the circumference of the induction shaft (343) and elastically supported by the spring support member (342), so that the elastic force generated by the induction spring (344) by the piston movement of the induction shaft (343) is supported by the spring support member (342), thereby moving the induction shaft (343).

[0101] It is preferable that a 'C' shaped induction head (347) be formed at the end of the induction shaft (343) and provided with the same shape as the circumference of the removal unit drive gear (320).

[0102] In addition, a head groove (347a) is formed at the rear end of the guide head (347), and an guide ball (345) formed at the end of the guide shaft (343) is built into the head groove (347a).

[0103] When two ball mounting members (346) are placed in the head groove (347a) to surround the circumference of the guide ball (345), each ball mounting member (346) is elastically supported by a ball support spring (348), so that the guide ball (345) can flexibly support the guide head (347) that supports the removal unit drive gear (320) by elastically moving in the head groove (347a), thereby pushing the removal unit body (220) from the removal unit drive gear (320) and guiding it so that it can move along the removal unit moving rail (210).

[0129] The assembly relationship and the effect of the embodiment according to the above configurations are described in detail based on the drawings as follows.

[0130] In the angle adjustment unit (400), the first upper and lower frames (410a) and the first side frame (410b) are fastened in a 'ㅁ' shape, and as shown in the drawing, the upward diagonal portion (410d), the angle adjustment groove (410c), and the downward diagonal portion (410e) are assembled to form the first side frame (410b). (Assembly 1)

[0131] Additionally, the second upper and lower frames (420a) and the second side frames (420b) are fastened in a 'ㅁ' shape. (Assembly 2)

[0132] The assembly 2 shape is formed narrower than the assembly 1 shape.

[0133] Install Assembly 1 on Assembly 2 so that it overlaps as shown in the drawing.

[0134] The control unit rotation frame (430) is inserted so as to pass through the second side frame (420b) and the first side frame (410b).

[0135] In addition, the adjustment gear (440) is movably fastened by engaging with the angle adjustment groove (410c), and the adjustment gear (440) is installed at both ends of the adjustment unit rotation frame (430) so as to be rotatable in the vertical direction.

[0136] A control cylinder (460) is installed vertically toward the first upper and lower frames (410a) in the central portion of the control rotation frame (430) as shown in the drawing.

[0137] A control rod shaft (450) is inserted toward the control cylinder (460) in the center of the first upper and lower frame (410a) so that piston movement is possible.

[0138] When the operator pushes the second upper and lower frames (420a) to rotate the adjustment unit rotation frame (430) to adjust the angle of the keyboard body (10), the adjustment gear (440) moves diagonally along the angle adjustment groove (410c) so that the adjustment unit cylinder (460) moves in a piston motion toward the adjustment unit rod shaft (450) to form an angle.

[0139] In the gear buffer unit (470), a buffer unit base plate (471) is installed vertically at both ends of the angle adjustment groove (410c) as shown in the drawing.

[0140] A buffer support shaft (472) is installed horizontally on each buffer base plate (471).

[0141] A buffer body (473) is inserted into the periphery of the buffer support shaft (472), and the buffer support shaft (472) is built into a body groove (473a).

[0142] A buffer head (476) is formed at the end of the buffer support shaft (472), and the buffer head (476) is made of a material such as rubber or polyurethane that can alleviate the impact caused by the movement of the adjustment gear (440).

[0143] A buffer spring (475) is inserted into the circumference of the buffer support shaft (472) and is placed between the buffer head (476) and the buffer body (473).

[0144] Additionally, a buffer member (474) formed of an elastic material such as rubber, silicone, or polyurethane is built into both inner sides of the buffer body (473).

[0145] In the horizontal alignment part (477), the alignment part lifting body (4771) is inserted horizontally around the periphery of the buffer part support shaft (472).

[0146] One end of a custom-fit lifting body (4771) is rotatably connected to one end of a custom-fit rotating frame (4775) and is provided so as to face a buffer member (474).

[0147] A custom elastic shaft (4772) is formed vertically downward from the center of the custom lifting body (4771) and is built into the interior of the buffer support shaft (472).

[0148] At this time, the custom elastic shaft (4772) is formed into a shape that is easy to change shape, such as rubber or silicone.

[0149] When the custom-fit lifting body (4771) is raised and lowered based on the buffer support shaft (472), the shape of the custom-fit elastic shaft (4772) is deformed, and the buffer spring (475) generates elastic force, allowing the custom-fit lifting body (4771) to be raised and lowered repeatedly elastically.

[0150] At this time, in order to support this, a custom support housing (4773) is built into the inside of the buffer support shaft (472) and is fixed to the lower end of the custom elastic shaft (4772) so as to support the shape deformation of the custom elastic shaft (4772) and the elastic force of the custom spring (4774).

[0151] As the custom lift body (4771) is raised and lowered, the custom roller (4776) rotates in the body groove (473a) so that the custom lift body (4771) can be supported by the custom rotation frame (4775) that can rotate based on the custom lift body (4771).

[0152] By transmitting and absorbing the shock applied through the buffer head (476) to the buffer member (474) by the embodiment of the horizontal alignment part (477), the risk of the buffer body (473) losing balance and being damaged can be reduced.

[0153] If the horizontal alignment part (477) is not provided, the shock applied to the shock absorber head (476) may cause the shock absorber body (473) to lose its balance from the shock absorber support shaft (472) and form an angle, thereby receiving the shock and losing the function of the gear shock absorber (470).

[0154] Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and various modifications may be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims. Furthermore, such modifications should not be understood individually from the technical idea or prospect of the present invention.
