본 고안은 잉크제트 프린터에 관한 것으로, 특히 헤드가 장착된 캐리지를 왕복운동시키는 타이밍벨트가 캐리지로 부터 이탈되지 않도록 예방하는 동시에 정확한 위치에 고정되도록 안출한 잉크제트 프린터의 캐리지 왕복운동장치에 관한 것이다.The present invention relates to an ink jet printer, and more particularly, to a carriage reciprocating device of an ink jet printer which is secured to be fixed in a correct position while preventing a timing belt for reciprocating the head mounted carriage from being separated from the carriage. .

일반적으로 잉크제트 프린터란 인자해야 할 문자를 도트매트릭스로 화소분할하여 각각의 화소가 갖는 위치정보에 비례한 전압으로 잉크입자를 대전시킨 다음 이를 정전장에서 편향하여 피마킹물(용지)에 도달시키므로서 화소문자를 인자시키도록 하는 프린터이다.In general, an ink jet printer divides a character to be printed into a dot matrix, charges ink particles with a voltage proportional to the positional information of each pixel, and deflects them in an electrostatic field to reach a marked object (paper). Printer that prints case letters.

이러한 프린터는, 메인프레임상에 지지되어 벨트풀리의 안내를 받아 타임벨트에 의하여 좌·우로 이동되는 캐리지와, 캐리지에 장착되어 캐리지와 함께 이동하면서 잉크를 분사하는 헤드와, 헤드에 설치되어 분사되는 잉크가 일정형태를 갖추어 분출되도록 하는 노즐과, 메인프레임에 회전가능하게 설치되어 용지를 이송시킴과 동시에 프린팅시 용지를 받쳐 주는 플레이튼과, 메인프레임에 고정되어 용지를 플레이튼에 밀착시켜주는 밀착판과, 프린팅시 일정한 주기로 크리닝 신호에 따라 헤드를 닦아주거나 밀폐시키는 와이퍼/캡부로 구성되어 있다.Such a printer is supported on the main frame and is moved to the left and right by a belt belt guided by a belt pulley, a head mounted on the carriage and moving with the carriage to inject ink, and installed on the head Nozzles to eject ink in a certain form, platens rotatably installed on the mainframe to transport paper and support the paper during printing, and close fixing to the platen to fix the paper to the platen. It consists of a plate and a wiper / cap that wipes or seals the head according to the cleaning signal at regular intervals during printing.

상기 캐리지(20)의 이동수단은 제1도와 같이, 양측 벨트풀리(40)에 권회된 타임벨트(10)에 캐리지(20)를 고정하여 벨트풀리(40)의 회전방향에 따라 타임벨트(10)를 좌·우로 이동시키게 되는 것이며, 그 타임벨트(10)에 의하여 캐리지(20)는 좌·우로 왕복운동하면서 캐리지(20)에 장착된 헤드로 용지에 프린팅하도록 하는 구조이다.As shown in FIG. 1, the moving means of the carriage 20 fixes the carriage 20 to the time belt 10 wound on both side belt pulleys 40 so that the time belt 10 is rotated along the rotational direction of the belt pulley 40. ) Is moved left and right, and the carriage 20 is reciprocated left and right by the time belt 10 so as to print on the paper by the head mounted on the carriage 20.

그런데 상기 벨트(10)와 캐리지(20)의 고정수단은 제2도와 같이, 캐리지(20)의 일측 내면에 타임벨트(10)의 이빨과 이빨홈크기와 동일한 요철부(22)를 만곡면으로 돌출형성하며, 그 요철부(22)에 맞물려서 횡방향으로 통과하는 타임벨트(10)의 양측을 협지하는 협지부(24)를 요철부(22)의 전방 양측에 형성하여 벨트(10)와 캐리지(20)를 일체로 고정하였던 것이다.By the way, the fixing means of the belt 10 and the carriage 20, as shown in Figure 2, on one inner surface of the carriage 20, the same concave-convex portion 22 of the teeth and the tooth groove size of the time belt 10 to the curved surface Gripping portions 24 are formed on both front sides of the concave-convex portion 22 so as to sandwich the both sides of the time belt 10 that are engaged with the concave-convex portion 22 and pass in the transverse direction, thereby forming the belt 10 and the carriage. (20) was integrally fixed.

그러나 캐리지(20)의 양측 협지부(24)가 타임벨트(10)를 협지하고 있어도 반복적인 왕복운동시 금속재보다는 유연한 재질의 타임벨트(10)의 이빨이 캐리지(20)의 요철부(22)에서 이탈하게 되는 경우가 발생하게 되며, 이때 양측 협지부(24)가 타임벨트(10)를 양측에서 협지하고 있어도 타임벨트(10)의 이빨이 요철부(22)에서 이탈한 상태에서는 협지력이 소멸되어 타임벨트(10)와 캐리지(20)사이에 슬라이딩에 발생하게 되므로, 타임벨트(10)가 좌·우 이동하더라도 캐리지(20)는 정확하게 왕복운동할 수 없는 문제점이 있었다.However, even if both side gripping portions 24 of the carriage 20 hold the time belt 10, the teeth of the time belt 10 of a flexible material, rather than a metal material, may be uneven portions 22 of the carriage 20 during repeated reciprocating movements. In this case, the clamping force is reduced in the state in which the teeth of the time belt 10 are separated from the uneven portion 22 even when both gripping portions 24 hold the time belt 10 from both sides. Since the disappearance occurs in the sliding between the time belt 10 and the carriage 20, even if the time belt 10 moves left and right, there was a problem that the carriage 20 can not reciprocate correctly.

본 고안은 이러한 종래의 문제점을 해결하고자 하는 것으로, 헤드가 장착된 캐리지를 왕복운동시키는 타이밍벨트가 캐리지로 부터 이탈되지 않도록 예방하는 동시에 정확한 위치에 고정토록 잉크제트 프린터의 캐리지왕복운동장치를 제공하는데 그 목적 있다.The present invention is to solve the conventional problems, to provide a carriage reciprocating device of the inkjet printer to prevent the timing belt for reciprocating the head mounted carriage from being separated from the carriage and to be fixed in the correct position. There is that purpose.

본 고안은 이러한 목적을 달성하기 위하여 잉크제트 프린터의 캐리지왕복운동장치를, 전방벽의 내측면에 타임벨트의 이빨형상과 동일하게 형성되어 맞물리도록 하는 요철부와, 전방벽의 하부에 장공으로 관통되는 걸림구멍으로 형성된 캐리지와 ; 측단면상 ㄷ자형으로 절곡된 상·하 자유단 끝부분에 하방으로 걸림턱을 각각 돌출형성하여 전방벽의 상단과 걸림구멍에 각각 고정되어 타임벨트를 전방벽에 밀착고정되도록 하는 벨트홀더를 구성하여, 반복적인 왕복운동시 벨트홀더에 의하여 타임벨트가 캐리지로 부터 이탈되지 못하고 견고하게 고정이 되고, 또한 조립불량의 방지와 정확한 위치에 조립을 하므로서 프린터의 품질을 향상시키도록 한 것이 본 고안의 특징이다.In order to achieve the above object, the present invention provides a carriage reciprocating device of an ink jet printer, having an uneven portion to be formed on the inner surface of the front wall in the same manner as the teeth of the time belt, and through the long hole at the bottom of the front wall. A carriage formed by a locking hole to be used; The belt holder is formed at the top and bottom of the front wall and fixed to the top of the front wall by fastening the locking jaws downwardly at the upper and lower free end portions bent in a U-shape on the side cross section. The characteristic of the present invention is that the belt is fixed firmly by the belt holder during repeated reciprocating movements, and the quality of the printer is improved by preventing assembly failure and assembling at the correct position. to be.

이하 본 고안을 첨부도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도면 제3도 및 제4도에서 잉크제트 프린터의 캐리지왕복운동장치를, 전방벽(21)의 내측면에 타임벨트(10)의 이빨형상과 동일하게 형성되어 맞물리도록 하는 요철부(22)와, 전방벽(21)의 하부에 장공으로 관통되는 걸림구멍(23)으로 형성된 캐리지(20)와 ; 측단면상 ㄷ자형으로 절곡된 상·하 자유단 끝부분에 하방으로 걸림턱(31)(32)을 각각 돌출형성하여 전방벽(21)의 상단(21a)과 걸림구멍(23)에 각각 고정되어 타임벨트(10)를 전방벽(21)에 밀착고정되도록 하는 벨트홀더(30)로 구성한다.3 and 4, the carriage reciprocating device of the ink jet printer is formed on the inner side of the front wall 21 in the same manner as the teeth shape of the time belt 10, and the uneven portion 22 is engaged. A carriage 20 formed at a lower portion of the front wall 21 by a locking hole 23 penetrating through a long hole; The locking jaws 31 and 32 are protruded downward from the upper and lower free end portions bent in the c-shape on the side cross-sections, respectively, and fixed to the upper ends 21a and the locking holes 23 of the front wall 21, respectively. Time belt 10 is configured as a belt holder 30 to be fixed in close contact with the front wall (21).

이와 같이 구성된 본 고안은, 타임벨트(10)는 그 이빨이 캐리지(20)의 전방벽(21)에 형성된 요철부(22)에 맞물리게 되고, 별도의 벨트홀더(30)로 타임벨트(10)를 감싸면서 상·하부 걸림턱(31)(32)이 전방벽(21)의 상단(21a)과 걸림구멍(23)에 각각 걸리도록 조립하면 되는 것이다.The present invention configured as described above, the time belt 10 is engaged with the concave-convex portion 22 formed on the front wall 21 of the carriage 20, the time belt 10 as a separate belt holder 30. The upper and lower locking jaws 31 and 32 may be assembled while being enclosed by the upper and lower ends 21a and the locking holes 23 of the front wall 21, respectively.

이때, 벨트홀더(30)의 조립시 먼저 하부측 걸림턱(32)를 걸림구멍(23)에 끼워서 걸리도록 한 뒤 상부측 걸림턱(31)에 외력을 가하여 탄력있게 전방벽(21)의 상단(21a)에 걸리게 되는 것이다.At this time, when assembling the belt holder 30, the lower locking jaw 32 is first inserted into the locking hole 23 to be caught, and then an external force is applied to the upper locking jaw 31 to elastically the upper end of the front wall 21. (21a) is caught.

따라서 타임벨트(10)는 전방벽(21)의 요철부(22)에 맞물리는 동시에 벨트홀더(30)에 의하여 감싸져 밀착이 되므로 타임벨트(10)의 이빨이 요철부(22)에서 이탈될 염려가 없는 것이다.Therefore, the time belt 10 is engaged with the concave-convex portion 22 of the front wall 21 and at the same time wrapped and wrapped by the belt holder 30 so that the teeth of the time belt 10 may be separated from the concave-convex portion 22. There is no concern.

이와 같이 본 고안은 캐리지의 반복적인 왕복운동시 벨트홀더에 의하여 타임벨트가 캐지리로 부터 이탈되지 못하고 견고하게 고정이 되고, 또한 정확하게 조립이 되므로 조립불량의 원인을 방지할 수가 있으며, 캐리지를 정확한 위치에 조립을 할 수가 있어 프린터의 품질을 향상시킬 수 있는 매우 유용한 고안인 것이다.As such, the present invention prevents the cause of assembly failure because the time belt is firmly fixed and accurately assembled by the belt holder during repeated reciprocating movement of the carriage. It is a very useful design to improve the quality of the printer can be assembled in place.
