Description

도트 프린터의 헤드 이송거리 조정장치Head feed distance adjusting device of dot printer

본 발명은 도트프린터에 있어서, 헤드의 정확한 이송거리를 조정할 수 있도록 한 헤드 이송거리 조정장치에 관한 것으로, 더욱 상세히는 헤드의 이송거리를 제 1,2 조정레버 및, 상기 제 1 조정레버와 연설되는 조정스크류로서 정밀하게 조정함으로써, 프린터의 수직인자 정열이 용이하게 수행되는 한편, 센서부품이 감소하여 조립 작업이 용이하게 수행될 수 있도록 한 도트 프린터의 헤드 이송거리 조정장치에 관한 것이다.The present invention relates to a head feeding distance adjusting device for adjusting an accurate feeding distance of a head in a dot printer, and more particularly, a head feeding distance of the head printer and a first adjusting lever and a first adjusting lever. By precisely adjusting the adjustment screw, the alignment of the vertical factors of the printer can be easily performed, while the sensor component is reduced, and the head feeding distance adjusting device of the dot printer can be easily performed.

일반적으로 알려진 종래의 도트 프린트의 헤드 이송거리 조정장치에 있어서는, 도 1 및 도 2 에서 도시한 바와 같이, 메인 기판(110)의 상측으로 횡설된 이송바아(122)에 직선 운동토록 연설된 헤드 이송블록(120)의 전방으로 도트프린터(100)의 헤드(130)가 연설되며, 상기 이송바아(122)를 따라 직선 운동하는 헤드이송블록(120)의 하측에는 감지편(124)이 설치되고, 상기 메인 기판(110)상으로 단부 좌우 양측에는 감지편(124)에 의하여 헤드 이송거리(L1)를 조정토록 감지하는 센서(140a)(140b)가 각각 착설되는 구성으로 이루어 진다.In the conventional head print distance adjusting device of the conventional dot print, as shown in Figs. 1 and 2, the head feed that is rolled in a linear motion to the transfer bar 122 rolled up to the upper side of the main substrate 110 The head 130 of the dot printer 100 is spoken in front of the block 120, the sensing piece 124 is installed on the lower side of the head transfer block 120 to linearly move along the transfer bar 122, Sensors 140a and 140b are installed on both sides of the left and right ends of the main board 110 so as to adjust the head feeding distance L1 by the sensing pieces 124.

따라서, 상기와 같은 종래의 도트 프린터의 헤드 이송거리 조정장치에 있어서는, 리셋(reset) 작업시 메인기판(110)에 착설된 좌,우측의 센서(140a)(140b)에 헤드(130)와 일체로 이송하는 헤드 이송블록(120)의 감지편(124)이 통과할 때 헤드(130)의 위치를 인식하여 이송거리(L1)를 조정하는데, 이와 같은 센서(140) 감지와 프린터 헤드(130)의 수직인자 정렬(프린팅 된 끝선의 정열상태 즉, 직선으로 형성되어야 한다)을 비교하여 상기 메인 기판(110)의 위치를 조정하면서 헤드(130)의 이송거리(L1)를 조정토록 하는 것이다.Therefore, in the head feed distance adjusting device of the conventional dot printer as described above, the head 130 is integrated with the left and right sensors 140a and 140b mounted on the main board 110 during the reset operation. When the sensing piece 124 of the head transfer block 120 to be transferred to pass through and recognizes the position of the head 130 to adjust the transport distance (L1), such sensor 140 and the printer head 130 By comparing the vertical factor of the alignment (that is, the alignment of the printed end line should be formed in a straight line) by adjusting the position of the main substrate 110 to adjust the feed distance (L1) of the head 130.

그러나, 상기와 같은 종래의 도트 프린터의 헤드 이송거리 조정장치에 있어서는, 도 1 및 도 2 에서 도시한 바와 같이, 메인기판(110)에 설치된 양측 센서(140a)(140b)와 헤드 이송블록(120)의 감지편(122)에 의한 헤드 이송거리(L1)를 감지토록 한후, 프린터 헤드(130)의 수직인자 정렬을 비교 조정하고 메인기판(110)의 위치를 조정해야 하는 복잡한 조정작업으로 인하여, 작업성이 저하됨은 물론, 센서(1400가 설치된 기판(110)을 조정해야 하므로 미세한 조정작업이 어렵게 되는 문제가 있었다.However, in the head feed distance adjusting apparatus of the conventional dot printer as described above, as shown in Figs. 1 and 2, both sensors 140a and 140b and the head feed block 120 provided on the main substrate 110, respectively. After detecting the head feed distance (L1) by the sensing piece 122 of the), due to the complicated adjustment work to compare and adjust the vertical factor alignment of the print head 130 and to adjust the position of the main substrate 110, As well as deterioration in workability, the sensor 110 needs to adjust the substrate 110 on which the sensor 1400 is installed.

또한, 메인 기판(110)에 포토센서(140)를 설치하고, 상기 센서(140)에 의하여 감지되는 감지판(122)은 헤드 이송블록(120)에 설치됨으로 인하여, 고정상태의 센서(140a)(140b)에 이동하는 감지판(122)이 센서 작동함으로 인하여, 감지 작동의 불량율이 높게되는 문제가 있었다.In addition, since the photosensor 140 is installed on the main substrate 110, and the sensing plate 122 detected by the sensor 140 is installed in the head transfer block 120, the sensor 140a in a fixed state. Due to the sensor operation of the sensing plate 122 moving to 140b, there was a problem that the defective rate of the sensing operation is high.

또한, 두 개의 포토센서(140)를 사용함으로 인하여, 부품 비용이 증가하여 프린터의 제조원가가 상승하는 등의 여러 문제점들이 있었다.In addition, due to the use of the two photosensors 140, there are a number of problems, such as an increase in the manufacturing cost of the printer due to the increase in component costs.

본 발명은 상기와 같은 종래의 여러 문제점들을 개선시키기 위하여 안출된 것으로서 그 목적은, 직선 운동하는 헤드 이송블록의 하측으로 센서를 설치하여 메인 프레임상에 설치된 제 1, 2 조정레버의 감지판을 인식함으로써, 센서의 감지작동이 보다 정밀하게 수행되는 도트 프린터의 헤드 이송거리 조정장치를 제공하는 데에 있다.The present invention has been made in order to improve the various problems as described above, the object is to recognize the sensing plate of the first and second adjustment levers installed on the main frame by installing a sensor under the linear movement of the head transfer block The present invention provides a head feeding distance adjusting device for a dot printer in which a sensing operation of a sensor is performed more precisely.

또한, 본 발명의 다른 목적은, 고정된 제 2 조정레버와 조정스크류로서 미세이동하는 제 1 조정레버로서 헤드 이송거리(L2)를 조정함으로써, 헤드의 이송거리 조정이 극히 정밀하게 수행되고, 이에 따라 프린터의 수직인자 정열이 보다 정밀하게 이루어 져 프린터의 제품 신뢰성이 향상되는 도트 프린터의 헤드 조정장치를 제공하는 데에 있다.In addition, another object of the present invention, by adjusting the head feed distance (L2) as the fixed second adjustment lever and the first adjustment lever to move finely as the adjustment screw, the adjustment of the feed distance of the head is carried out extremely precisely, Accordingly, the present invention provides a dot printer head adjusting device in which vertical alignment of the printer is more precisely performed, thereby improving product reliability of the printer.

It is made of a configuration that is formed.

상기와 같은 구성으로 이루어 진 본 발명의 작용을 상세하게 설명하면 다음과 같다.Referring to the operation of the present invention made in the above configuration in detail as follows.

도 3 내지 도 6 에서 도시한 바와 같이, 도트 프린터에 있어서, 헤드(24)의 이성거리(L2)를 용이하게 조정하면서도 조정스크류(60)와 연동하는 제 1 조정레버(40)와 제 2 조정레버(50)로서 보다 정밀하게 헤드(24)의 이송거리(L2)를 조정할 수 있는 한편, 하나의 센서(30)만을 설치하여 부품수가 감소하고 조립도 용이한 도트 프린터의 헤드 조정장치(1)는 다음과 같다.3 to 6, in the dot printer, the first adjustment lever 40 and the second adjustment interlocking with the adjustment screw 60 while easily adjusting the distance L2 of the head 24 are easily adjusted. As the lever 50, the feeding distance L2 of the head 24 can be more precisely adjusted, while the head adjusting device 1 of the dot printer 1 which reduces the number of parts and easily assembles by installing only one sensor 30 is provided. Is as follows.

먼저, 도 3 에서 도시한 바와 같이, 헤드 이송거리(L2)를 조정하는 경우에는 헤드(24)에 의해 프린팅된 수직인자 정렬이 중요한데, 이는 헤드(24)가 프린팅 작동시 이동 시작점(S)에서 이동 끝점(E)까지 프린팅 작동후, 다시 이동 끝점(E)에서 이동 시작점(S)으로 프린팅 작동하고, 따라서 상술한 바와 같이, 수직인자가 직선으로 정렬되어야만, 프린터의 헤드 이송거리(L2)가 일정하게 되는 것이다.First, as shown in FIG. 3, when adjusting the head feed distance L2, the alignment of the vertical factors printed by the head 24 is important, which means that the head 24 moves at the start point S during the printing operation. After the printing operation to the moving end point E, the printing operation from the moving end point E to the moving start point S is again performed. Therefore, as described above, the vertical factor must be aligned in a straight line so that the head feed distance L2 of the printer It becomes constant.

이와 같은 헤드(24)의 이송거리(L2)는 헤드(24)가 설치된 헤드 이송블록(20)의 일측으로 연설된 센서부(30)에 의하여 조정하는데, 도 3 및 도 4 에서 도시한 바와 같이, 상기 헤드 이송블록(20)는 프린터의 메인 프레임(10)의 상측으로 횡설된 이송바아(22)를 따라 직선 운동토록 연설되며, 결국 상기 헤드 이송블록(20)의 일측 하부에 설치된 센서부(30)도 일체로 직선 운동한다.The feeding distance L2 of the head 24 is adjusted by the sensor unit 30 extended to one side of the head feeding block 20 in which the head 24 is installed, as shown in FIGS. 3 and 4. The head conveying block 20 is linearly oriented along the conveying bar 22 which is horizontally rolled up to the upper side of the main frame 10 of the printer, and eventually the sensor unit installed at one lower side of the head conveying block 20 ( 30) straight line movement integrally.

이때, 도 4에서 도시한 바와 같이, 상기 센서부(30)는 발광센서(30a)와 수광센서(30b)로 된 포토센서로 구성되는 한편, 상기 메인 프레임(10)의 좌우 양측에 설치되는 제 1,2 조정레버(40)(50)의 제 1,2 감지판(42)(52)이 상기 발광센서(30a)와 수광센서(30b) 사이에 위치되면, 상기 발광센서(30a)에서 방출된 신호를 수광센서(30b)에서 수신할수 없고, 따라서 헤드 이송블록(20)의 이송이 정지되며, 결국 상기 제 1,2 감지판(42)(52)의 위치는 헤드(240의 이동 시작점(S) 및 이동 끝점(E)이 되며, 따라서 상기 제 1,2 감지판(42)(52)은 헤드 이송블록(20)와 일체로 직선운동하는 센서부(30)의 이동선상에 위치되어야 한다.At this time, as shown in Figure 4, the sensor unit 30 is composed of a photo sensor consisting of a light emitting sensor (30a) and a light receiving sensor (30b), while being installed on both left and right sides of the main frame (10) When the first and second detection plates 42 and 52 of the first and second adjustment levers 40 and 50 are positioned between the light emitting sensor 30a and the light receiving sensor 30b, the light emitting sensor 30a emits the light. The received signal cannot be received by the light receiving sensor 30b, and thus the feeding of the head transport block 20 is stopped, and thus the position of the first and second sensing plates 42 and 52 is the starting point of movement of the head 240 ( S) and the moving end point E, and thus the first and second sensing plates 42 and 52 should be positioned on the moving line of the sensor unit 30 linearly moving integrally with the head transfer block 20. .

더하여, 도 5에서 도시한 바와 같이, 제 1 감지판(42)은, 조정스크류(60)가 나사 결합되는 나사홈(40a)이 일측면 상부에 형성된되고, 이와 수직방향에는 메인 프레임(10)의 일측벽에서 돌출된 고정판(10b)에 지지되는 지지판(40b)이 형성된 제 1 조정레버(40)의 하측으로 연설된다.In addition, as shown in FIG. 5, the first sensing plate 42 has a screw groove 40a to which the adjusting screw 60 is screwed is formed on one side, and the main frame 10 in the vertical direction. The support plate 40b, which is supported by the fixing plate 10b protruding from one side wall of the support plate 40b, is formed below the first adjustment lever 40.

따라서, 상기 조정스크류(60)를 회전시키면 일체로 제 2 조정바아(40)의 지지판(40b)이 프레임의 고정판(10b)에 지지되면서 조정스크류(60)의 회전량에 따라 전후 이동되고, 이와 같은 조정스크류(60)에 의한 미세한 이동은 결국 제 1 감지판(42)의 위치가 미세하게 전후 조정되고, 결국 헤드(24)의 이송거리(L2)가 미세하게 조정되는 것이다.Accordingly, when the adjusting screw 60 is rotated, the supporting plate 40b of the second adjusting bar 40 is integrally supported by the fixed plate 10b of the frame and moved back and forth according to the rotation amount of the adjusting screw 60. The minute movement by the same adjusting screw 60 is that the position of the first sensing plate 42 is finely adjusted back and forth, and eventually the feeding distance L2 of the head 24 is finely adjusted.

이에 더하여, 상기 제 2 감지판(52)이 설치된 제 2 조정레버(50)는, 제 1 조정레버(40)의 타측으로 메인프레임(10)상에 착설되어 고정됨으로써, 결국 상기 제 2 감지판(52)을 헤드(24)의 이동 끝점(E)으로 맞추어 고정시키면, 제 1 감지판(42)의 위치는 헤드(24)의 이동 시작점(S)이 되고, 도 6 에서 도시한 바와 같이, 헤드(24)의 실제 프린팅 거리(D2)와 제 1,2 감지편(42)(52)의 간격(D1) 차이만큼 제 1 감지판(42)을 미세 조정하면, 헤드(24)의 실제 프린팅 거리(D2)와 제 1,2 감지판(42)(52)간의 간격(D1)이 일치하게 되고, 따라서 센서(30)의 이동거리가 조정됨으로써, 상술한 바와 같은, 헤드 이송거리(L2)도 일치되어 조정되며, 프린팅된 수직인자 정렬이 직선상으로 이루어 지는 것이다.In addition, the second adjusting lever 50 provided with the second sensing plate 52 is installed on the main frame 10 to be fixed to the other side of the first adjusting lever 40, whereby the second sensing plate is finally fixed. When 52 is fixed to the moving end point E of the head 24, the position of the first sensing plate 42 becomes the moving start point S of the head 24, as shown in FIG. When the first sensing plate 42 is finely adjusted by the difference between the actual printing distance D2 of the head 24 and the distance D1 between the first and second sensing pieces 42 and 52, the actual printing of the head 24 is performed. The distance D1 between the distance D2 and the first and second sensing plates 42 and 52 coincides with each other, and thus, the movement distance of the sensor 30 is adjusted, whereby the head feed distance L2 as described above. The alignment is also adjusted and the printed vertical factor alignment is in a straight line.

한편, 도 1 및 도 3 에서 도시한 바와 같이, 종래에는 두 개의 센서(140)를 기판(110)상에 설치하는 것에 비하여, 하나의 센서부(30)를 설치하여 부품수가 절감됨으로써, 고가의 센서가 감소되어 부품 비용이 절감되는 한편, 특히 메이기판(110)의 센서(140)위치를 조정하는 것에 비하여 헤드 이송거리(L2)의 조정작업이 극히 용이한 것이다.On the other hand, as shown in Figures 1 and 3, compared with the conventional installation of two sensors 140 on the substrate 110, by installing one sensor unit 30, the number of parts is reduced, expensive While the sensor is reduced to reduce the parts cost, in particular, the adjustment of the head feed distance (L2) is extremely easy compared to adjusting the position of the sensor 140 of the main substrate 110.

이와 같이 본 발명인 도트 프린터의 헤드 이송거리 조정장치에 의하면, 센서의 감지작동이 보다 정밀하게 수행되는 한편, 고정된 제 2 조정레버와 조정스크류로서 미세 이동하는 제 1 조정레버로서 헤드 이송거리(L2)를 조정함으로써, 헤드의 이송거리 조정이 극히 정밀하게 수행될 뿐만 아니라, 프린터의 수직인자 정열이 보다 정밀하게 이루어 져 프린터의 제품 신뢰성이 향상되는 우수한 효과가 있는 것이다.As described above, according to the head feeding distance adjusting device of the dot printer of the present invention, the sensing operation of the sensor is performed more precisely, while the head feeding distance L2 is used as the first adjusting lever which is finely moved as the fixed second adjusting lever and the adjusting screw. By adjusting), the feeding distance of the head is not only extremely precisely adjusted, but also the vertical alignment of the printer is more precisely performed, thereby improving the product reliability of the printer.
