제2도 내지 제4도에 도시한 바와 같이, 지지간(11)(12)이 절결형성된 핀치로울러암(13)의 전방단부를 기기 본체의 데크기판(도시되지 않음)상에 축핀(14)으로 축착하고 일측 지지간(11)의 선단부에는 핀치로울러(15)를 축착하며 타측 지지간(12)의 원호상 절곡부(16) 양측에는 가이드포스트(17)(18)를 각각 입설하는 동시에, 그 핀치로울러암(13)의 일측변부 양측에는 작동핀(19)(20)을 각각 상, 하향으로 돌출형성하여 이와 같이된 핀치로울러암(13)의 작동핀(20)에는 공지 펑션플레이트(21)의 일측단부에 형성한 밀편(22)의 경사면(22a)과 수평면(22b)에 접촉되게 하고 상기 축핀(14)에는 핀치로울러암(13)을 반시계방향으로 탄지하는 토션스프링(23)을 설치하는 한편, 핀치로울러암(13)의 후방에 구동기어(24)를 축핀(25)으로 축착하고 구동기어(24)의 축핀(25) 상측부에는 넓은 직경의 원호면(26a)과 작은직경의 원호면(26b) 및 만곡면(26c)(26d)을 가지는 캠(26)을 고정하며 또한, 구동기어(24)의 전방에 축핀(27)으로 축착한 작동레버(28)의 일측단부에는 접촉핀(29)를 입설하고 중간부에는 일측단이 기판상에 고정된 코일스프링(30)의 타단을 고정하며 그 작동레버(28)의 타측단부에는 상기 핀치로울러암(13)의 작동핀(19)에 접촉되는 접촉부(31)를 절곡형성한 것으로, 도면중 미설명부호 32은 캡스턴축을 보인 것이다.As shown in Figs. 2 to 4, the front end of the pinch roller arm 13, in which the supporting rods 11 and 12 are cut, is formed on the deck board 14 (not shown) of the main body of the device. And pinch rollers 15 on the front end of one support section 11 and guide posts 17 and 18 on both sides of the arcuate bent portion 16 of the other support section 12, respectively. On both sides of one side of the pinch roller arm 13, the actuating pins 19 and 20 are protruded upward and downward, respectively, so that the actuating pin 20 of the pinch roller arm 13 has a known function plate ( A torsion spring 23 for contacting the inclined surface 22a and the horizontal surface 22b of the push piece 22 formed at one end of the side 21 and holding the pinch roller arm 13 counterclockwise on the shaft pin 14. On the other hand, the drive gear 24 is fixed to the rear of the pinch roller arm 13 with the shaft pin 25, and the upper side of the shaft pin 25 of the drive gear 24 is wide. The cam 26 having the circular arc surface 26a of the diameter, the circular arc surface 26b of the small diameter, and the curved surface 26c, 26d is fixed, and it is affixed with the shaft pin 27 in front of the drive gear 24. A contact pin 29 is inserted into one end of the actuating lever 28, and the other end of the coil spring 30 fixed to the substrate is fixed to the middle of the actuating lever 28, and the pinch is attached to the other end of the actuating lever 28. The contact portion 31 in contact with the actuating pin 19 of the roller arm 13 is bent, and the reference numeral 32 in the drawing shows the capstan shaft.

이와 같이된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention as described above is as follows.

제2도는 본 고안의 작동되지 않고있는 상태를 보인 것으로, 이때에는 핀치로울러암(13)에 입설된 핀치로울러(15)가 캡스턴축(32)과 분리되어 있다. 이러한 상태에서 펑션플레이트(21)가 우측으로 이송되어 그 밀편(22)의 경사면(22a)이 핀치로울러암(13)의 작동핀(20)을 밀게되면 핀치로울러암(13)이 토션스프링(23)의 힘을 이기고 시계방향으로 회전하게 되며, 이와 동시에 구동기어(24)가 별도의 구동수단에 의하여 반시계방향으로 회전하게 된다.2 is a view showing the non-operational state of the present invention, in which the pinch roller 15 placed in the pinch roller arm 13 is separated from the capstan shaft 32. In this state, when the function plate 21 is transferred to the right side and the inclined surface 22a of the contact piece 22 pushes the operation pin 20 of the pinch roller arm 13, the pinch roller arm 13 is torsion spring 23. ) And rotate clockwise, and at the same time the drive gear 24 is rotated counterclockwise by a separate drive means.

이와 같이 하여 핀치로울러암(13)의 작동핀(20)이 펑션플레이트(21)의 경사면(22a) 하단부에 접촉되고 작동레버(28)의 접촉핀(29)이 캠(26)의 만곡면(26d)에 근접한 제3도의 상태를 경과한 후 펑션플레이트(21)와 구동기어(24)가 계속구동됨에 따라 핀치로울러암(13)의 작동핀(20)이 펑션플레이트(21)의 밀편(22) 수평면(22b)에 접촉되면서 핀치로울러암(13)의 일측 지지간(11)에 입설된 핀치로울러(15)가 캡스턴축(32)에 접촉되고 이와 동시에 작동레버(28)의 접촉핀(29)은 캠(26)의 만곡면(26d)에 접촉되면서 코일스프링(30)이 수축되고 그에 따라 작동레버(28)가 축핀(27)을 중심으로 하여 반시계 방향으로 회동하게 되고 그의 접촉부(31)가 핀치로울러암(13)의 작동핀(19)을 밀어 시계방향으로 회동시키게 되므로 핀치로울러(15)가 캡스턴축(32)에 압착된다.In this way, the actuating pin 20 of the pinch roller arm 13 comes into contact with the lower end of the inclined surface 22a of the function plate 21 and the contact pin 29 of the actuating lever 28 is curved surface of the cam 26 ( As the function plate 21 and the drive gear 24 continue to drive after the state of FIG. 3 close to 26d), the actuating pin 20 of the pinch roller arm 13 is pushed to the function plate 21. ) The pinch roller 15, which is in contact with the horizontal surface 22b and is inserted into one support section 11 of the pinch roller arm 13, contacts the capstan shaft 32 and at the same time the contact pin 29 of the actuating lever 28. ) Is in contact with the curved surface (26d) of the cam 26, the coil spring 30 is contracted so that the operating lever 28 is rotated counterclockwise around the shaft pin (27) and its contact portion 31 ) Is rotated clockwise by pushing the operation pin 19 of the pinch roller arm 13, the pinch roller 15 is pressed to the capstan shaft (32).

이와 같이된 상태에서 구동기어(24)가 반시계 방향으로 계속회전하여 캠(26)의 원호면(26b)과 작동레버(28)의 접촉 핀(29)이 제4도에 도시한 상태에 도달하게 되면 작동레버(28)에는 코일스프링(30)력이 작용하여도 그 접촉부(31)가 핀치로울러암(13)의 작동핀(19)에 접촉되어 있으므로 캠(26)의 원호면(26b)과 작동레버(28)의 접촉핀(29) 사이에는 일정간격(t)이 유지되어지고 이 간격(t)에 의하여 핀치로울러(15)가 적절한 탄성으로 압착되어 진다.In this state, the drive gear 24 continues to rotate in the counterclockwise direction so that the arc surface 26b of the cam 26 and the contact pin 29 of the actuating lever 28 reach the state shown in FIG. In this case, since the contact portion 31 is in contact with the actuating pin 19 of the pinch roller arm 13 even though the coil spring 30 acts on the actuating lever 28, the arc surface 26b of the cam 26 is provided. A predetermined interval t is maintained between the contact pin 29 of the actuating lever 28 and the pinch roller 15 is compressed to an appropriate elasticity by the interval t.

한편, 언로딩시에는 펑션플레이트(21)가 좌측으로 이동하면 토션스프링(23)의 힘에 의하여 반시계 방향으로 회전하여 원래위치로 복원하게 되고 작동레버(28)는 캠기어(26)가 계속 반시계방향으로 회전함에 따라 그의 접촉핀(29)이 캠곡선을 타고 외측으로 밀림에 따라 시계방향으로 회전하고 인장스프링(30)은 인장되어 원상태로 복귀한다.On the other hand, during unloading, if the function plate 21 moves to the left side, it rotates counterclockwise by the force of the torsion spring 23 to restore the original position, and the operating lever 28 keeps the cam gear 26 continuously. As it rotates counterclockwise, its contact pin 29 rotates clockwise as it is pushed outward on the cam curve, and the tension spring 30 is tensioned to return to its original state.

상기한 바와 같이된 본 고안은 핀치로울러의 압착 메카니즘을 핀치로울러암과 작동레버의 2중 링크로 구성한 간소화된 구조로 되어 있으므로 동작의 신뢰성을 높일 수 있을 뿐아니라 제작을 간편하게 하고 제조원가를 절감할 수 있으며 제품의 소형화에 기여하는 이점이 있다.The present invention as described above has a simplified structure consisting of a pinch roller arm and a double link of the actuating lever to the crimping mechanism of the pinch roller, which not only increases the reliability of the operation but also facilitates the manufacture and reduces the manufacturing cost. And it has the advantage of contributing to the miniaturization of the product.

그외에 핀치로울러암의 지지간에 형성된 원호상 절곡부에 가이드포스트를 일체로 구비시켜 함께 구동시키는 효과도 있다.In addition, the guide post is integrally provided with the arc-shaped bent portion formed between the support of the pinch roller arm to drive together.
