본 발명은 소형 프린터의 종이 이송장치에 있어서, 이송급지되는 프린터용 종이가 이송 방향으로만 급지될 수 있도록 하고 역회전하는 방향으로는 이동되지 않도록 하여 종이 이송장치의 클러치 손상을 방지하며 평행도가 양호한 상태로 인자헤드에의 급지가 이루어질 수 있도록 한 종이 이송장치의 역회전 방지장치에 관한 것이다.In the paper conveying device of a small printer, the present invention allows the paper for feeding the printer to be fed only in the conveying direction and does not move in the reverse rotation direction, thereby preventing damage to the clutch of the conveying paper and having good parallelism. The present invention relates to a reverse rotation prevention device of a paper feeder, which allows feeding to a print head in a state.
일반적인 소형 프린터에 있어서의 종이급지 및 이송장치는 인자헤드의 일방에 급지 이송부를 설치하고 이 급지 이송부에 공급롤러와 종이롤러를 서로 접촉상태로 설치하여 이들 롤러 사이에 급지되는 종이를 공급하도록 되어 있었으며 상기 급지, 이송되는 종이는 인자헤드의 인자 동작에 따라 연결된 기어의 동작으로 인자줄만큼의 간격을 두고 이송, 급지되도록 되어 있었는바, 이와 같은 종래의 것은 이송되는 종이의 역회전 장치가 없었기 때문에 인자도중 외부의 힘에 의하여 이송, 급지되던 종이가 역으로 빠져 나올 염려가 있었으며, 또 상기 종이의 이탈이 용이함에 따라 인자줄의 이동에 따른 정확한 종이의 이송이 어렵게 되었음은 물론, 급지시의 종이 평행도가 흔들려 자칫 인자되는 문자가 경사지게 되거나 불균일하게 되는 등의 문제점이 있었다.The paper feeding and conveying device in a typical small printer was provided with a feed feeder on one side of the print head, and a feed roller and a paper roller were placed in contact with each other to feed paper fed between these rollers. The paper feeding and conveying paper was conveyed and fed at intervals as much as print lines by the operation of the connected gear according to the printing operation of the printing head. Such a conventional printing method does not have a reverse rotation device of the paper to be conveyed. There was a concern that the paper that was conveyed and fed by the external force on the way would come out in reverse. Also, as the paper was easily separated, the paper was difficult to move correctly due to the movement of the printing line. Problems such as slanting or non-uniformity It was.
본 고안은 상기와 같은 종래의 제반 문제점을 감안하여 안출한 것으로 급지, 이송되는 종이의 역회전을 방지하고 또, 강제 역회전시 종이는 역으로 빠져 나오지 않으면서 클러치가 손상되지 않도록 한 것인바, 이를 이하에서 첨부한 도면과 실시예에 의거하여 상세히 설명하면 다음과 같다. 구동모터의 동작에 따라 플레튼과 인자헤드가 작동되고 이와 동시에 종이 급지 및 이송수단이 작동되어 프린트되도록 하는 소형 프린터에 있어서, 프린터의 기체(1)의 전방에 급지롤러(2)와 종이롤러(3)를 각각의 축(4)(5)으로 설치한 급지, 이송부(A)를 설치하고, 상기 축(4)에는 급지기어(6)와 노브(8)가 형성된 연동기어(7)가 대향 설치되며, 상기 축(5)에는 상기 연동기어(7)와 치합되는 기어(9)를 설치하고, 상기 급지기어(6)의 내주에는 래칫기어(601)를 설치하여 이에 래칫(10)가 치합되어 일방향으로만 회전하도록 하며, 상기 급지기어(6)에는 간헐치차군(12)과 전동기어군(13)이 함께 형성된 아이들러기어(11)를 치합설치하고 이에 무치차부(15)가 형성된 클러치(14)를 설치하여 구성된 것이다.The present invention has been made in view of the above-mentioned conventional problems to prevent the reverse rotation of the paper to be fed, conveyed, and to prevent the clutch from being damaged without forcibly coming out of the paper during forced reverse rotation, This will be described below in detail with reference to the accompanying drawings and embodiments. In a small printer in which the platen and print head are operated in accordance with the operation of the drive motor, and at the same time, the paper feed and transfer means are operated to print, the paper feed roller 2 and the paper roller in front of the body 1 of the printer. 3) A paper feeder and a feeding part A provided with the respective shafts 4 and 5 are provided, and the interlocking gear 7 in which the feed gear 6 and the knob 8 are formed is opposed to the shaft 4. The shaft 5 is provided with a gear 9 to be engaged with the interlocking gear 7 and a ratchet gear 601 is installed at an inner circumference of the feed gear 6 so that the ratchet 10 is engaged. To rotate only in one direction, the feed gear (6) is engaged with the idler gear (11) formed with the intermittent gear group (12) and the electric gear group (13) and the clutch (14) with the gearless portion (15) formed thereon. ) Is configured by installing.
이상과 같이 구성된 본 발명 실시예는 기체(1)의 일방 클러치(14)가 구동 모터의 구동수단에 의하여 회전하게 되면 이의 무치차부(15)에 도달할 때까지 아이들러기어(11)의 전동기어(13)군을 회전시켜 급지기어(56)를 회동시키게 되며, 이에 따라 축(4)으로 연결된 노브(8)를 가진 연동기어(7)가 축(5)에 설치된 기어(9)를 회동시켜 급지롤러(2)와 종이롤러(3)로 구성된 급지, 이송부(A)를 작동시키게 되고 프린트를 위한 종이의 급지 및 이송이 이루어지게 되며, 상기 아이들러기어(11)의 간헐치차군(12)군과 클러치(14)의 무치차부(15)에 위하여 간헐적회전 즉, 인자줄에 따른 회전이 이루어지게 된다.According to the embodiment of the present invention configured as described above, when the one clutch 14 of the base 1 rotates by the driving means of the driving motor, the electric gear of the idler gear 11 is reached until it reaches the gearless portion 15 thereof. 13) rotate the group to rotate the feed gear 56, so that the interlocking gear (7) having a knob (8) connected to the shaft (4) is rotated to feed the gear (9) installed on the shaft (5) The paper feeding and conveying unit (A) consisting of a roller (2) and a paper roller (3) is operated to feed and convey paper for printing, and the intermittent gear group (12) group of the idler gear (11) and Intermittent rotation, that is, rotation along the print string, is performed for the valueless portion 15 of the clutch 14.
상기와 같이 종이가 급지, 이송되어 인자되는 과정에서 급지되던 종이에 역으로 힘을 가하거나 하게 되면, 상기 급지기어(6)의 래칫기어(601)와 래칫(10)에 의하여 급지기어(6)를 포함하는 급지롤러(2)의 역회전이 방지되며, 상기 래칫기어(601)와 래칫(10)에 의하여 급지기어(6)가 축(4)의 회전없이 공회전하므로 종이의 역회전이 방지된다. 한편, 상기 급지되던 종이를 역으로 빼내고자 할 때는 축(4)에 설치된 연동기어(7)의 노프(8)를 회전시키면, 동력전달 수단의 동력 전달없이 종이를 빼낼 수 있으며, 이때 클러치(14)에는 역회전으로 인한 부하가 걸리지 않아 그 손상이 방지되는 것으로 소형 프린터에 공급되어 이송되는 종이의 역회전을 방지하면서 클러치등 동력전달 수단의 손상을 방지할 수 있고도 종이의 원활한 급지와 이송을 도모하므로서 종이의 평행공급을 도모할 수 있으며, 정확한 프린트작업이 이루어질 수 있게 되는 점 등의 특징을 지닌 것이다.When the paper is fed, conveyed and printed as described above, if a force is applied to the paper being fed in reverse, the ratchet gear 601 and the ratchet 10 of the paper feed gear 6 by the feed gear 6 Reverse rotation of the feed roller (2) comprising a; and the feed gear (6) by the ratchet gear 601 and the ratchet (10) by idling without rotation of the shaft (4) to prevent the reverse rotation of the paper . On the other hand, if you want to remove the paper fed back in reverse rotation of the knob (8) of the interlocking gear (7) installed on the shaft (4), it is possible to remove the paper without transmitting power of the power transmission means, the clutch 14 ) Is prevented from being damaged due to the reverse load, which prevents the reverse rotation of the paper which is supplied to the small printer and prevents the damage of the power transmission means such as the clutch. By planning, the parallel feeding of paper can be achieved, and the features such as accurate printing can be achieved.
