타자기의 프린터 헤드 구동장치Typewriter's print head drive

제1도는, 본 고안의 요부 발췌 사시도.1 is a perspective view showing the main parts of the present invention.

제2도는, 종래 장치의 요부 발췌 사시도.2 is a perspective view illustrating main parts of a conventional apparatus.

* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1 : 구동축 2 : 헤드1: drive shaft 2: head

3 : 캐리지 4 : 솔레노이드3: carriage 4: solenoid

6 : 레버 8 : 인장스프링6: lever 8: tension spring

본 고안은 헤드의 위치에 관계없이 항상 헤드가 일정한 압력으로 플라텐과 접촉될 수 있도록한 타자기의 프린터 헤드 구동장치에 대한 것이다.The present invention is directed to a typewriter printer head drive that allows the head to always be in contact with the platen at a constant pressure, regardless of the position of the head.

종래의 타자기는 제2도에서와 같이 플라텐(9)에 인자헤드(2')가 접촉되게하는 것은 솔레노이드의 구동력을 이용하여 길게 성형된 레버(6')가 헤드의 하단을 쳐주면 헤드(2')의 인자부가 Q각 만큼 회전되어 플라텐(9)에 접촉될 수 있도록 한 것이다.In the conventional typewriter, the print head 2 'is brought into contact with the platen 9, as shown in FIG. 2, when the lever 6' formed by using the driving force of the solenoid hits the bottom of the head. The printing portion of 2 ') is rotated by the Q angle so as to be in contact with the platen 9.

그러나 이러한 방식은 레버(6')에 걸리는 솔레노이드의 구동력은 통상 500-1500g의 힘을 필요로 하는데 레버(6')가 솔레노이드의 작동 지점에서 멀어지게 되면 레버(6')가 헤드(2')를 ″Q″각 만큼 회전시켜 주는 힘이 적어지거나 또는 균등하지 못하게 되어 프린트된 상태가 일정하지 않게 되며, 또 장기간 사용시 레버(6')가 변형될 경우 결국 헤드(2')의 접촉상태가 변경되어 역시 프린트 상태가 좋지 못하게되는 폐단이 있었다.However, in this method, the driving force of the solenoid applied to the lever 6 'usually requires a force of 500-1500g. When the lever 6' is moved away from the solenoid's operating point, the lever 6 'is moved to the head 2'. Force to rotate by ″ Q ″ angle decreases or becomes inconsistent, resulting in an inconsistent printed state, and the contact state of the head 2 'eventually changes when the lever 6' is deformed during long-term use. There was also a discontinuation of the print status was not good.

본 고안은 이와같은 점들을 해결하기 위해 캐리지의 저면에 솔레노이드를 부착하여 그 축선단에 연결된 레버의 전면부로 헤드의 하단부를 걸어 주도록 하므로 헤드의 위치에 관계없이 플라텐과 헤드의 접촉력이 항상 일정하게 되도록 고안한 것으로 첨부 도면에 의거 상술하면 다음과 같다.In order to solve these problems, the solenoid is attached to the bottom of the carriage, and the lower end of the head is hooked to the front part of the lever connected to the shaft end so that the contact force between the platen and the head is always constant regardless of the position of the head. The present invention will be described in detail with reference to the accompanying drawings as follows.

구동축(1)에 좌우 이동되게 끼워지는 헤드(2)의 하단을 캐리지(3)의 저면에 부착된 솔레노이드(4)의 축(5)선단에 연결한형상의 레버(6)선단부로 걸어 주고 헤드(2)의 상단과 캐리지(3)의 지지간(7)사이에 인장스프링(8)을 탄력설치하여서 된 것이다.The lower end of the head 2 fitted to the drive shaft 1 to be moved left and right is connected to the tip of the shaft 5 of the solenoid 4 attached to the bottom of the carriage 3. The tension spring 8 is elastically installed between the upper end of the head 2 and the support section 7 of the carriage 3 by walking to the tip of the lever 6 in the shape.

미설명 부호 ″9″는 플라텐이다.Unexplained symbol ″ 9 ″ is platen.

이와같이 구성된 본 고안은 프린트시 헤드(2)와 캐리지(3)가 구동축(1)을 따라 동시에 이동되는데 이러한 캐리지(3)의 저면에 솔레노이드(4)를 부착 시켰기 때문에 이역시 헤드(2)와 동시에 이동되면서 문자 신호가 입력 되어 솔레노이드(4)가 작동되면 그 축(5)이 레버(6)를 당겨주게되고 이에 따라 레버(6)의 선단부(a)가 헤드(2)의 하단부(b)를 당겨 주므로 헤드(2)는 구동축(1)을 중심으로 회전되므로 그 상단의 인자부(C)가 ″Q″각 만큼 회전되어 플라테(9)에 접촉되는 것이며, 이렇게하여 프린트가 된 다음 솔레노이드(4)의 작동이 정지되면 헤드(2)는 ″Q″각 만큼 회전될 때 그 간격만큼늘어났던 인장스프링(8)의 수축력으로 원상태로 되돌아가 다음 프린트 작동이 진행될 수 있도록 된다.According to the present invention, the head 2 and the carriage 3 are simultaneously moved along the drive shaft 1 during printing. Since the solenoid 4 is attached to the bottom of the carriage 3, the head 2 and the carriage 3 are simultaneously moved at the same time. When the text signal is input and the solenoid 4 is operated, the shaft 5 pulls the lever 6 so that the leading end a of the lever 6 moves the lower end b of the head 2. Since the head 2 is rotated about the drive shaft 1, the head C is rotated about the drive shaft 1 so that the printing part C at the top thereof is rotated by the ″ Q ″ angle to be brought into contact with the plate 9, and thus printed and then the solenoid 4 ) Is stopped, the head 2 is returned to its original state by the contracting force of the tension spring 8, which is extended by the interval when it is rotated by the ″ Q ″ angle, so that the next print operation can proceed.

이와같이 본 고안은 솔레노이드(4)를 캐리지(3)의 저면에 부착하여 이에의해 연동되는 레버(6)로 헤드(2)의 하단부를 걸어 주도록 하였기 때문에 헤드(2)와 솔레노이드(4)가 동시에 이동되므로 헤드(2)의 위치에 관계없이 항상 일정한 힘으로 헤드(2)가 작동되게 하여 주게되어, 프린트 상태가 양호하게 되는 매우 효과적인 고안이다.As such, the present invention attaches the solenoid 4 to the bottom of the carriage 3 so that the lower end of the head 2 is hooked by the lever 6 interlocked by the head 2 so that the head 2 and the solenoid 4 move simultaneously. Therefore, the head 2 is always operated with a constant force regardless of the position of the head 2, so that the printing state is very effective design.
