이와 같이 조립한 본 발명에 관한 원고압착판 개폐장치(5)는 도 1에 나타낸 바와 같이 통상 한쌍용이고, 지지부재(10)의 후단부를 원고압착판(3)의 후단부 하면에 부착한 후, 특히 도 2에 나타낸 바와 같이 장치본체(2)의 뒷부분 상단에 형성된 부착공(2a, 2a)(한쪽만 도시함)에 취부부재(7)의 취부다리부(6)를 삽입시켜 그의 부착편(6a)을 부착나사(16)로 나사고정함으로서 원고압착판(3)을 장치본체(2)로 개폐가능하게 부착할 수 있는 것이다. The original platen switch opening and closing device 5 according to the present invention thus assembled is usually for a pair, as shown in Fig. 1, and after the rear end of the supporting member 10 is attached to the bottom surface of the rear end of the platen plate 3, In particular, as shown in FIG. 2, the mounting leg 6 of the mounting member 7 is inserted into the mounting holes 2a and 2a (shown only one side) formed at the upper end of the rear part of the apparatus main body 2 so that the attachment piece ( By screwing 6a) with the attachment screw 16, the original pressing plate 3 can be attached to the apparatus body 2 so that it can be opened and closed.

다음에, 본 발명에 관한 원고압착판 개폐장치(5)의 작용에 대하여 설명하면, 위에서 설명한 바와 같이 원고압착판(3)을 장치본체(2)에 부착하고, 원고압착판(3)을 닫은 상태에 있어서, 회전제어수단(17)의 롤러(12)는 특히 도5에 나타낸 바와 같이 스프링가이드(15)의 한쪽부측에 위치하게 하고, 탄성수단(14)의 탄성력에 의해 지지부재(10)를 원고압착판(3)이 닫히는 방향으로 회전동작 힘을 가하게 됨으로서 원고압착판(3)은 자체 중량과, 탄성수단(14)의 탄성력에 의해 콘택트유리(4) 위로 압착되고 있다. 다만, 이때는 탄성수단(14)의 탄성력이 롤러(12)에 작용하지 않도록 그의 유효 길이를 정하여도 좋다.Next, the operation of the document pressing plate opening and closing device 5 according to the present invention will be described. As described above, the document pressing plate 3 is attached to the apparatus main body 2, and the document pressing plate 3 is closed. In the state, the roller 12 of the rotation control means 17 is located on one side of the spring guide 15, in particular as shown in Fig. 5, and the support member 10 is driven by the elastic force of the elastic means 14. By applying a rotational operation force in the direction in which the original pressing plate 3 is closed, the original pressing plate 3 is pressed onto the contact glass 4 by its own weight and the elastic force of the elastic means 14. In this case, however, the effective length may be determined so that the elastic force of the elastic means 14 does not act on the roller 12.

이 경우에는 원고압착판(3)은 그의 자체 중량만으로 닫힌 상태를 유지하고 있다.In this case, the document press plate 3 is kept closed only by its own weight.

이와 같이 원고압착판(3)의 닫힌 상태에서, 콘택트유리(4) 위에 원고를 얹어놓기 위하여 그 원고압착판(3)을 열게 행하면, 힌지핀(9)을 지점으로 함께 회전하는 지지부재(10)에 의해 요동부(11)의 회전제어수단(17)을 구성하는 롤러(12)는 스프링가이드(15)를 개재하여 탄성수단(14)을 약간 압입하므로서 그의 상면을 슬라이딩하여 이동하고, 도 6에 나타낸 바와 같이 원고압착판(3)이 콘택트유리(4) 즉, 장치본체(2)에 대하여 대략 8°의 열림 각도가 되었을 때 탄성수단(14)의 중심작용선과 힌지핀(9) 및 롤러(12)의 중심을 잇는 직선이 평행으로 되므로서 지지부재(10)는 어떤 방향에서도 회전동작 힘을 가하지 않는 상태가 된다.As described above, when the document pressing plate 3 is opened in order to place the original on the contact glass 4 in the closed state of the platen pressing plate 3, the support member 10 which rotates the hinge pins 9 together to the point. The roller 12 constituting the rotation control means 17 of the swinging portion 11 is moved by sliding the upper surface thereof by slightly pressing the elastic means 14 through the spring guide 15, As shown in Fig. 2, when the document pressing plate 3 has an opening angle of approximately 8 ° with respect to the contact glass 4, that is, the apparatus body 2, the center line of action of the elastic means 14, the hinge pin 9 and the roller Since the straight line connecting the center of (12) becomes parallel, the support member 10 is in a state in which no rotational motion force is applied in any direction.

또한, 원고압착판(3)을 열게 되면 탄성수단(14)에 의해 힘을 가하는 방향이 반전하여 이번에는 원고압착판(3)을 열리는 방향으로 힘을 가하여 도 7에 나타낸 바와 같이 지지부(10b)의 스토퍼부(10g)가 취부부재(7)의 폐색부(8a)에 맞닿을 때까지 열린다. 또한, 이 8°의 열림 각도에 한정되는 것은 아니다.In addition, when the document pressing plate 3 is opened, the direction in which the force is applied by the elastic means 14 is reversed, and this time the force is applied in the direction in which the document pressing plate 3 is opened, as shown in FIG. The stopper portion 10g is opened until it comes in contact with the blocking portion 8a of the mounting member 7. In addition, it is not limited to this opening angle of 8 degrees.

그 후에, 열린 원고압착판(3)은 열린 방향으로 힘을 가하게 된 상태로 되는 것이어서, 그 원고압착판(3)은 닫힌 방향으로 자연 낙하하는 것이 열린상태를 유지하는 것이 된다.Thereafter, the open original pressing plate 3 is in a state of applying a force in the open direction, so that the original pressing plate 3 naturally falls in the closed direction to maintain the open state.

이 열린각도는 실시예의 것으로서 대략 50°이지만, 이 열린각도에 대해서도 한정되는 것은 아니다.Although this open angle is about 50 degrees as an example, it is not limited also about this open angle.

다음에, 열려진 원고압착판(3)을 닫을 때에는 대략 8°까지의 닫힌 각도까지로 탄성수단(14)을 롤러(12)를 개재하여 압입할 때의 저항으로 만나지만, 대략 8° 에서 힌지핀(9)과 롤러(12)의 중심선과, 탄성수단(14)의 작용중심선이 일치한 이후에는 탄성수단(14)이 롤러(12)를 위쪽의 원고압착판(3)을 닫는 방향으로 미는 탄력이 작용하여, 원고압착판(3)은 자체중량과 탄성수단(14)의 가하는 힘에 의해 자동적으로 닫히게 된다.Next, when closing the open document pressing plate 3, the elastic means 14 meets the resistance when press-fitting the roller 12 through the roller 12 to a closed angle up to approximately 8 °, but the hinge pin at approximately 8 °. (9) and the center line of the roller 12 and the center of action of the elastic means 14, the elastic means 14 is the elastic force to push the roller 12 in the direction to close the upper platen plate 3 By this action, the document pressing plate 3 is automatically closed by its own weight and the force applied by the elastic means 14.

이상에서 설명한 바와 같이 이 실시예1에 관한 원고압착판 개폐장치(5)는 회전제어수단(17)에 의해 지지부재(10)의 회전제어를 통하여 원고압착판(3)의 닫힌 상태에서는 그 원고압착판(3)의 벌어짐 현상이 발생하지 않는 안정된 닫힘 상태를 유지할 수 있고, 소정의 개폐각도에서는 원고압착판(3)을 열린 방향으로 힘을 가하여 전체 열림 각도를 안정적으로 그 원고압착판(3)을 지지시켜둘 수 있는 다음에, 원고압착판(3)의 닫힘 조작 시에 놓여서는 그 원고압착판(3)이 급격히 닫히지 않도록 제어할 수 있는 것이다.As described above, the document crimping plate opening and closing apparatus 5 according to the first embodiment has the document in the closed state of the document crimping plate 3 through the rotation control of the supporting member 10 by the rotation control means 17. It is possible to maintain a stable closed state in which the unevenness of the crimping plate 3 does not occur, and at a predetermined opening and closing angle, a force is applied to the document crimping plate 3 in the open direction so that the entire opening angle is stably stabilized. ), The document pressing plate 3 can be controlled so as not to close rapidly when the document pressing plate 3 is placed in the closing operation.

또한, 롤러(12)를 설치한 것은 특히 중량이 가벼운 원고압착판(3)의 개폐조작 시에, 요동부(11)와 스프링가이드(15) 사이의 미끄러짐을 좋게 하여 개폐조작을 스무즈(smooth)하게 하는 효과가 있다.In addition, the installation of the roller 12 smoothes the opening / closing operation by making the sliding part 11 and the spring guide 15 smooth during opening / closing operation of the light weight plate 3, which is light in weight. ) Is effective.
