본 고안은 전자식 타자기에서 2열 프린트휠을 상하로 구동시켜 프린트휠의 내측·외측열에 배치되어 있는 캐랙터(Character)를 선택하여 인자시키는 프린트휠의 상하구동장치에 관한 것으로, 프린트휠과 구동모우터를 플렉시블 축으로 연결하고 고정힌지에 유착시킨 프린트휠축에 유설시킨 작동구를 중심으로 상하 위치에 설치시킨 전자석에 의해 작동구를 변위시켜 프린트 휠의 인자가 선택되도록 하였으며, 작동구를 상·하 스프링으로 탄설시켜 전자석이 작동하지 않을 때에는 중립위치에 위치하도록 하여 상·하 스프링으로 지지토록 하였다.The present invention relates to a vertical wheel driving device of a print wheel which drives a two-row print wheel up and down in an electronic typewriter to select and print a character disposed in the inner and outer rows of the print wheel. Is connected to the flexible shaft and the actuator is displaced by the electromagnet installed in the up and down position around the actuator placed on the print wheel shaft attached to the fixed hinge so that the print wheel parameters can be selected. When the electromagnet was not operated, it was placed in the neutral position and supported by the upper and lower springs.

종래에는 직류모터(D.C motor)를 이용하여 프린트휠(Printwheel)과 프린트휠 구동 서어브 모터(Servo motor)를 함께 상하로 구동시킨 방법이 주로 많이 사용되어 왔는데, 이 방법은 직류(D.C) 모터로 어느정도의 시간만큼 구동시키고 나머지는 회전관성 및 스프링에 저장된 탄성에너지로서 구동이 완료되도록 되어있기 때문에 동작이 완료된후 관성에 의한 운동에너지와 스프링내 탄성에너지등이 감쇄되어 캐랙터부위가 진동을 멈추어 인자가 가능하기까지의 시간이 걸리므로 그만큼 타이핑 속도가 느려지는 경향이 있으며 또한 작동구의 장공부분이나 크랭크판이 마모되어 프린트휠의 변위거리에 오차가 생겨 그에 따른 인자 위치에 오차가 생길 우려가 있었다.Conventionally, a method of driving a print wheel and a print wheel driving servo motor together up and down by using a DC motor has been mainly used, and this method is a DC motor. Since the driving is completed by the time of, and the rest is driven by the rotational inertia and the elastic energy stored in the spring, the kinetic energy by the inertia and the elastic energy in the spring are attenuated after the operation is completed. Since it takes a long time to do so, the typing speed tends to be slowed down, and the long hole of the operating tool or the crank plate is worn, and an error occurs in the displacement distance of the print wheel, thereby causing an error in the printing position.

더구나 이때 직류(D.C)모터는 일정각도의 회전만을 하게 되므로 모터 브러쉬(Brush)가 손상되어 이로인한 모터성능 저하와 수명감소를 초래할 가능성이 있고 프린트휠과 함께 프린트휠 구동을 위한 서어보모터를 들어올리는 관계로 모터의 중량으로 인해 더 많은 구동력을 필요로 하였던 것이다.In addition, since the DC motor only rotates at a certain angle, the motor brush may be damaged, which may result in deterioration of motor performance and lifespan.The servo motor for driving the print wheel together with the print wheel In relation to the lifting, the weight of the motor required more driving force.

본 고안은 프린트휠 구동모우터와 프린트휠 사이를 플렉시블축으로 연결시켜 전자석을 이용하여 프린트휠만을 따로 상하로 이동시키는 장치로서 플렉시블축(Flexible shaftl)은 회전중에도 구동축과 피동측의 상대위치를 반경시킬 수 있고, 전달효율이 우수하고 취급도 간편한 잇점이 있는 것이다.The present invention connects the print wheel drive motor and the print wheel with a flexible shaft and moves the print wheel up and down separately using an electromagnet. The flexible shaft has a radius of the relative position between the drive shaft and the driven side during rotation. It has the advantage that it can be made, the delivery efficiency is excellent and the handling is easy.

따라서, 본 고안은 종래에 비하여 회전전달기구 장치를 간소화시키고 동작이 신속하며 기계적인 부하가적어 소요동력이 적게 드는 장점이 있는 것이다.Therefore, the present invention has the advantage of simplifying the rotation transmission mechanism device compared to the prior art, the operation is fast, and the mechanical load is low and the required power is low.

이를 첨부도면에 의하여 설명하면 다음과 같다.This will be described with reference to the accompanying drawings.

프린트휠(1)이 축설된 프린트휠축(2)과 구동모우터(10)를 플렉시블축(3)으로 연결시켰으며, 일축을 고정힌지(4)로 유착시키고, 프린트휠축(2)에 유설시킨 작동구(5)를 형성하여 프린트휠(1)을 상·하 이동시키기 위한 동력원으로서 작동구(5)를 중심으로 상·하 위치에 설치시킨 2개의 전자석(6)(6')에 접동되게 하여서 고정힌지(4)를 중심으로 프린트휠(1)을 상·하 변위시키게 하였다.The print wheel shaft 2 and the driving motor 10 in which the print wheel 1 has been connected are connected with the flexible shaft 3, and one shaft is adhered to the fixed hinge 4, and the print wheel shaft 2 is mounted on the print wheel shaft 2. It is formed to actuate the two electromagnets 6 and 6 'installed at the up and down position around the actuating tool 5 as a power source for forming the actuating tool 5 to move the print wheel 1 up and down. By doing so, the print wheel 1 was displaced up and down about the fixed hinge 4.

또한 고정힌지(4)로부터 일정거리에 상·하 위치에 텐션스프링(7)(7')을 설치하여 전자석(6)(6')에 의해 작동되는 작동구(5)의 상·하 구동을 텐션을 갖게 하고 전자석(6)(6')이 작동하지 않을때는 스프링(7)(7')에 의해 중립위치에서 지지토록 설치한 것으로 미설명부호 8는 플레이튼이고, 9는 햄머이다.In addition, the tension springs 7 and 7 'are provided at an upper and lower positions at a predetermined distance from the fixed hinge 4 to drive up and down of the operation tool 5 operated by the electromagnets 6 and 6'. When the electromagnets 6 and 6 'are not operated, they are installed to be supported in the neutral position by the springs 7 and 7', and reference numeral 8 is platen and 9 is hammer.

이와 같이 된 본 고안의 작용효과를 상술하면, 상·하 전자석(6)(6')이 작동하지 않으면 도면 제2도와 같이 중립위치에 스프링(7)(7)에 의해 지지되어 있다가 플레이턴(8)에 프린트휠(1)의 내측열을 인자하고자 할 경우에는 상전자석(6)에 전류를 흐르게 하면 자력이 발생하여 중립위치에 있던 작동구(5)가 고정힌지(4)를 중심으로 상단측으로 이동함에 따라 프린트휠(1)이 상부로 이동되어서 햄머(9)로 내측열을 인자시킬 수 있는 것이고, 프린트휠(1)의 외측열을 인자하고자 할 경우에는 하전자석(6')에 전류를 흐르게 하면 자력이 발생하여 작동구(5)는 고정힌지(4)를 중심으로 하단측으로 이동되어 프린트휠(1)을 하부로 이동시켜서 햄머(9)에 의해 외측열을 인자시킬 수 있는 것이다.In detail, the above-described effect of the present invention, if the upper and lower electromagnets 6, 6 'do not operate, they are supported by the springs 7 and 7 in the neutral position as shown in FIG. In the case of printing the inner heat of the print wheel 1 in (8), when a current flows through the upper electromagnet 6, a magnetic force is generated so that the operating hole 5 in the neutral position is centered around the fixed hinge 4. As the print wheel 1 moves to the upper side, the inner row can be printed by the hammer 9, and when the outer row of the print wheel 1 is to be printed on the lower electromagnet 6 '. When a current flows, a magnetic force is generated, and the actuating tool 5 is moved to the lower side about the fixed hinge 4 to move the print wheel 1 downward, thereby printing external heat by the hammer 9. .

이때 프린트휠(1)을 구동시키는 구동모우터(10)와 프린트휠(1)이 플렉시블축(3)으로 연결되어 있어서 작동구(5)에 의해 프린트휠(1)의 상·하 이동에 따라 구동모우터(10)가 프린트휠(1)과 함께 이동시키지 않고 구동모우터(10)을 고정시킨 상태에서 프린트휠(1)만 상·하 이동시켜 전달효율이 좋고 회전전달기구 장치가 간단하여 모우터의 중량에 의한 더 많은 구동력이 필요없이 프린트휠(1)의 캐랙터 부위가 진동을 멈추어 인자가 가능하기까지의 시간을 단축시키어 타이핑 속도를 높일 수 있는 것이다.At this time, the driving motor 10 for driving the print wheel 1 and the print wheel 1 are connected by the flexible shaft 3, so that the operating wheel 5 moves up and down by the operating hole 5. Since the drive motor 10 is not moved together with the print wheel 1 and the drive motor 10 is fixed, only the print wheel 1 moves up and down, so that the transmission efficiency is good and the rotation transmission mechanism device is simple. It is possible to increase the typing speed by shortening the time until the character of the character of the print wheel 1 stops vibration and prints without requiring more driving force by the weight of the motor.

제2도에서 상세히 설명하면 여기서 α는 작동구(5)의 회전각도이며, d는 프린트휠(1)의 내측·외측열에 배치되어 있는 캐랙터 사이의 간격, 즉 작동구의 수직이동 거리이다.In detail in FIG. 2, α is an angle of rotation of the actuating tool 5, and d is an interval between the characters arranged in the inner and outer rows of the print wheel 1, that is, the vertical movement distance of the actuating tool.

L는 힌지(hinge)점(O1)과 프린트휠(1)의 중심(O2)까지의 거리이고, ℓ은 힌지점(O1)에서 스프링(7)(7')까지의 거리이다. 프린트휠(1)의 스포크(spoke) 사이의 각을 β라 할때 작동구(5)의 회전각도 α는 β의 정수배가 되도록 하여 상하구동시 n스포크(n spoke)만큼 이동한 효과를 갖도록 해야 한다.L is the distance from the center of the hinge (hinge) point (O 1) and print wheel (1) (O 2), ℓ is the distance from the spring (7) (7 ') in hinge points (O 1). When the angle between the spokes of the print wheel 1 is β, the rotation angle α of the operating tool 5 should be an integer multiple of β so that it has an effect of moving by n spokes during up and down driving. do.

β와α의 값은 프린트휠(1)이 결정되면 일정한 수이므로 α는 n에 의해서 결정된다. 일단 α의 값을 결정하면 거리 L은 식 L=d/ 2 sin. α/ 2에 의해서 정해진다. α가 커지면 L이 작아지고 α가 작아지면 L이 커지므로 α와 L 사이에 타협점을 택한다.Since the values of β and α are constant numbers when the print wheel 1 is determined, α is determined by n. Once the value of α is determined, the distance L is expressed by the formula L = d / 2 sin. determined by α / 2. If α is large, L becomes small, and if α is small, L becomes large, so a compromise point is chosen between α and L.

또한 한지점(O1)과 spring 까지의 거리 ℓ이 커짐에 따라 작동구를 전자석으로 들어올릴때 스프링의 변위가 더 커져 그에 따른 구동력이 더 필요하게 되므로 이 또한 적절한 점을 선정한다.Also, as the distance ℓ between the one point (O 1 ) and the spring increases, the displacement of the spring increases when lifting the operating tool into the electromagnet, which requires more driving force.

이와 같이 본 고안은 구동모우터(10)와 프린트휠(1) 사이를 플렉시블축(3)으로 연결시켜 전자석(6)(6')을 이용 프린트휠(1)만 따로 상·하 이동시키므로 전달효율이 우수하고 진동을 방지하며 구동전달기구를 간소화시켜 원활한 구동이 전달되도록 한 것이다.As such, the present invention connects the driving motor 10 and the print wheel 1 with the flexible shaft 3 so that only the print wheel 1 is moved up and down separately by using the electromagnets 6 and 6 '. It has excellent efficiency, prevents vibration and simplifies the drive transmission mechanism so that smooth driving can be transmitted.
