[Technical field to which the invention belongs]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wing switch, and more particularly, to a wing switch suitable for, for example, supporting a document pressing plate of a copying machine and a similar wing in a freely openable and closable manner.

[0002]

[Prior art]

 A hinge of a conventional opening / closing body which is the background of the present invention is disclosed in Japanese Utility Model Publication No. 4-35498. In this conventional hinge of the opening and closing body, an elastic member is housed between the arm member and the base member. Furthermore, it is possible to absorb the difference between the moment in the closing direction and the moment in the opening direction that fluctuates according to the opening degree of the opening / closing body, balance them, and perform free stop at the opening position of the opening / closing body. A variable power mechanism is provided.

However, when the above-described conventional technique is used for a document pressing plate of a copying machine, if the thickness of the copy document is large, such as in a dictionary, the document pressing plate is placed in a horizontal position with respect to the copy document. Since the document could not be held, there was a problem that the exposure of the copying machine was leaked or the like, and there was a possibility that the copied document could not be copied accurately.

On the other hand, there has been proposed a document pressing plate opening / closing device of a copying machine having a structure capable of holding a document pressing plate in a horizontal position with respect to a copying document even when the copying document is thick. This is disclosed in Japanese Utility Model Laid-Open No. 7-5142. This conventional document pressure plate opening / closing device has a pivot arm and a swing arm attached to the document pressure plate and pivotably supported at the tip of the pivot arm. In addition, between the engaging shaft, which is inserted into the long hole provided in the rotating arm and engages with the protrusion protruding from the lower edge of the swing arm, and the supporting shaft supported by the supporting frame. A spring is provided for urging the original cover in an opening direction via a swing arm. When copying a thick document, the swing arm pivots downward around the tip of the pivot arm and the document pressure plate becomes horizontal. And press it against the contact glass surface of the copier body.

[0005]

[Problems to be solved by the invention]

 However, in the conventional document pressing plate opening / closing device disclosed in Japanese Utility Model Application Laid-Open No. 7-5142, the urging force of a spring for pressing the document pressing plate in the opening direction is such that the engagement force is inserted into the slot of the rotary arm. The original cover is held horizontally by actuating the swing arm indirectly via a shaft, a projection of the swing arm, a pivot shaft that rotatably supports the swing arm, and the like. . As a result, the structure for lifting the swing arm horizontally was complicated. In addition, the range in which the original cover is set in a horizontal state is limited depending on the thickness of the copy original, and it has been difficult to deal with a copy original having an excessive thickness.

[0006] Therefore, a main object of the present invention is to provide a wing switch having a simple structure capable of adjusting the setting position of the fulcrum of the wing so as to be freely displaceable.

[0010]

[Embodiment of the invention] 【Example】

 FIG. 1 is an exploded perspective view showing an embodiment of the present invention, and FIG. 2 is a schematic plan view showing a main part of the wing switch of FIG. Although the present invention relates to a wing switch, the present embodiment describes a wing switch applied to, for example, a document pressing plate of a copying machine according to the present invention. The wing switch 10 includes a guide support base 12. The guide support base 12 has, for example, a rectangular support plate 14, and side walls 14 a and 14 b extending vertically upward from the end thereof are formed at one end and the other end in the length direction of the support plate 14, respectively. The whole is formed, for example, in a substantially U-shaped plate shape.

[0011] Guide rails 16a and 16b each having a substantially U-shaped cross section, for example, are opposed to inner wall surfaces of the side wall plates 14a and 14b as guide members. The guide rails 16a and 16b are opposed to each other when viewed in the length direction of the guide support base 12. Since the guide rails 16a and 16b have the same structure, only one guide rail 16b will be described. On the inner surfaces of the two opposing side walls 18 and 18 of the guide rail 16b, for example, grooves 20 and 20 having a substantially semicircular cross section are formed. In this case, a recess 17 is formed between the side walls 18 of the guide rail 16b. A slider 26 as a slide member to be described later is fitted into the recess 17. The guide support base 12 is attached to and fixed to an upper surface portion (not shown) of the main body of the copying machine by an appropriate attaching means.

The wing switch 10 includes a base member 22. The base member 22 includes, for example, a rectangular base plate 24. At both ends in the width direction of the base plate 24, side wall plates 24a and 24b extending vertically upward from the ends are formed.

A slider 26 having a U-shaped cross section, for example, is provided as a slide member on the outer wall surfaces of the side wall plates 24a and 24b. The slider 26 is configured as a protrusion fitted into the recess 17 of the guide rail 16. The slider 26 has rolling elements 30 each having a circular cross section on both side surfaces in the width direction. When the slider 26 is set on the guide rails 16a, 16b, the rolling elements 30 are fitted into the grooves 20 of the guide rails 16a, 16b. That is, the slider 26 is slidably guided along the planar slide surface 21 of the guide rail 16 via the rolling element 30. In this case, the contact surfaces 21a and 21b, which contact the guide rail 16 and the slider 26 in a plane, and the contact surfaces 31a, 31b, in which the rolling element 30 and the groove 20 of the guide rail 16 make an arc, are paired. They slide while contacting each other as elements.

Since the slider 26 of the present embodiment is formed in a U-shaped cross section, the slider 26 has an arc-shaped depression 28 on the other main surface side. The slider 26 has a recess 28 while its main surface is in contact with the slide surface 21 of the guide rail 16. Therefore, when the slider 26 slides along the concave portion 17 of the guide rail 16, an arc-shaped gap 32 is formed on the contact surface between the guide rail 16 and the slider 26.

The base member 22 is disposed on an upper surface (not shown) of the main body of the copying machine. In this case, the base member 22 is disposed between the inner wall surfaces of the side walls 14a and 14b of the guide support base 12, and is supported by the guide support base 12 so as to be slidable in the height direction of the copying machine, that is, in the vertical direction. .

Further, a substantially U-shaped frame-shaped arm member 34 is rotatably arranged on the base member 22. The arm member 34 includes a top plate 36 having a rectangular plate shape, and side wall plates 38a, 38b extending vertically downward from the ends thereof are formed at both ends in the width direction of the top plate 36. One end of the arm member 34 in the length direction is rotatably supported between the side wall plates 24a and 24b of the base member 22 by the first rotation shaft portion 40. A bearing portion 42 is disposed between the base member 22 and the arm member 34 at one end and the other end in the axial direction of the first rotation shaft portion 40, respectively.

In this case, for example, looking at the positional relationship between the base member 22, the arm member 34, and the bearing portion 42 at one axial end of the first rotating shaft portion 40, as shown in FIG. The distance between the outer wall surface of the side wall plate 24b of the member 22 and the inner wall surface of the side wall plate 38b of the arm member 34 is G1, and the side wall plate 24b of the base member 22 when the guide rail 16b and the slider 26 are set. Assuming that the distance from the outer wall surface to the outer wall surface of the side wall plate 14a of the guide support base 12 is G2, the bearing portion 42 is disposed between the base member 22 and the arm member 34 so as to satisfy G1> G2. . That is, the axial length of the bearing portion 42 is formed to be substantially the same as G1. The positional relationship between the base member 22, the arm member 34, and the bearing portion 42 at the other end of the first rotating shaft portion 40 in the axial direction has the same configuration. However, the length of the guide rails 16a, 16b in the longitudinal direction is reduced so that the side wall plates 38a, 38b of the arm member 34 do not contact the side wall plates 14a, 14b of the guide support base 12, or the arm member If the side wall shape of the side wall plates 38a, 38b of 34 is formed so as not to hit the side wall plates 14a, 14b of the guide support base 12, G1 <G2 may be satisfied. That is, as shown by a light black portion in FIG. 3, by providing, for example, an inverted T-shaped notch in the side wall plates 38a and 38b of the arm member 34, the side wall plates 14a and 14b of the guide support base 12 are connected to the arm members. The thirty-four side wall plates 38a and 38b may not be hit. In this case, since it is not necessary to satisfy G1> G2, the size in the width direction of the guide support base 12, the base member 22, and the arm member 34 can be reduced.

An urging means 44 for urging the arm member 34 in the door opening direction is provided between the base member 22 and the arm member 34. The biasing means 44 includes, for example, two movable supports 46, 46 arranged in parallel. Since the two movable supports 46 have the same structure and operation, only one movable support 46 will be described in this embodiment.

The movable support 46 includes a bottomed cylinder 48 and a covered cylinder 50. The inner diameter of the bottomed cylinder 48 is formed slightly larger than the outer diameter of the covered cylinder 50. The covered cylinder 50 is fitted in the bottomed cylinder 48 so as to be movable in the axial direction. In the circumferential direction of the peripheral wall of the bottomed cylinder 48, a plurality of slits 48a are arranged at intervals. The slit portion 48a is provided to extend in the axial direction of the bottomed cylindrical body 48. The bottom plate 52 of the bottomed cylindrical body 48 includes, for example, a rectangular flange portion 52a, and a bearing portion (not shown) is integrally formed at the center of the lower surface of the flange portion 52a with an interval in the length direction. Is formed.

On the outer peripheral wall of the covered cylinder 50, a rectangular band-shaped projection 50 a is provided at a position corresponding to the slit 48 a of the bottomed cylinder 48. The protruding portion 50a is formed to be shorter and narrower than the slit portion 48a, and can slide while contacting the inside of the slit portion 48a with an appropriate frictional force. The cover plate 54 of the covered cylindrical body 50 includes, for example, a rectangular flange portion 54a, and a bearing portion 56 is integrally formed at the center of the upper surface of the flange portion 54a with an interval in the length direction. You.

A coil spring 58 such as a compression spring is disposed around the movable support 46 as an urging member. In this case, the bottomed cylindrical body 48 is inserted through an opening (not shown) at one end in the axial direction of the coil spring 58, and the bottomed cylindrical body is inserted through an opening (not shown) at one end in the axial direction of the coil spring 58. 50 is inserted. Therefore, the coil spring 58 is locked between the flange 52 a of the bottomed cylinder 48 and the flange 54 a of the covered cylinder 50. Further, the movable support 46 has its bottomed tubular body 48 rotatably supported between the side wall plates 24a, 24b of the base member 22 by the second rotating shaft portion 60, and its covered tubular body 50. Is rotatably supported by the third rotating shaft 62 on the other end of the arm member 34 in the longitudinal direction.

Next, a description will be given of the movement of the wing switch 10 shown in the above-described embodiment when the wing switch 10 is opened and closed and when the base member 22 is lifted up. The arm member 34 can be opened and closed freely using the first rotation shaft 40 as a fulcrum. Since the arm member 34 is urged in the door opening direction by the urging means 44, as the opening angle of the arm member 34 increases, the movable support 46 of the urging means 44 extends, and the door opening angle increases. Becomes smaller, the movable support 46 is compressed.

When the covered cylinder 50 and the bottomed cylinder 48 are fitted together, when the contact area between the protrusion 50 a of the covered cylinder 50 and the inner wall surface of the bottomed cylinder 48 is gradually increased, Their frictional force is also gradually increased. Further, when the fitting length between the projection 50a and the slit 48a of the bottomed cylinder 48 is gradually increased, the contact area between the projection 50 and the inner wall surface of the bottomed cylinder 48 is gradually decreased. Therefore, their frictional force is also gradually reduced.

In the wing switch 10 of the present embodiment, for example, as shown in FIG. 3, when the thickness of the original placed on the upper surface P (original placing surface) of the copying machine is not so large, The arm member 34 to which the pressing plate (not shown) is attached is opened and closed with the first rotating shaft portion 40 as a fulcrum, and is pressed and held in a horizontal state with respect to the copy original. In this case, the slider 26 of the base member 22 is located at the lower end side in the height direction of the guide rails 16a and 16b provided on the guide support base 12. That is, this state shows an initial state in which the lower surface of the base member 22 is in contact with the upper surface of the support plate 14 of the guide support base 12 and the base member 22 is not lifted up.

When the thickness of the copy original is large, such as in a dictionary, first, an original pressing plate (not shown) is initially pressed against the copy original, so that a part of the original pressing plate is copied. The upper end of the document is brought into contact. Next, in this state, the front side of the document pressing plate is usually further pressed. Then, an upward force acts on the rear end side of the document pressing plate according to the principle of leverage with the contact point between the document pressing plate and the copy document as a fulcrum.

In this case, as described above, the base member 22 is slidably supported by the guide support base 12 in a direction perpendicular to the upper surface portion P (document mounting surface) of the copying machine main body. As shown in FIG. 4, for example, the base member 22 corresponds to the thickness of the document to be copied, and extends along the slide surface 21 of the guide rail 16 from the top surface P (document mounting surface) of the copying machine main body. It rises to height H. Therefore, the document pressing plate attached to the arm member 34 can be pressed and held while being lifted up in a horizontal state. Therefore, the pressing force can be applied almost uniformly to the copied document, and inconveniences such as leakage of exposure of the copying machine can be prevented.

FIG. 5 is a plan view showing a main part of a modification of the wing switch shown in FIGS. In this modification, the slider 26 is not particularly provided with the depression 28 as compared with the above-described embodiment. That is, when the slider 26 slides along the slide surface 21 of the recess 17 of the guide rail 16, no gap 32 is formed on the contact surface between the guide rail 16 and the slider 26. Therefore, the contact area of the contact surface between the guide rail 16 and the slider 26 is increased as compared with the above-described embodiment, and the frictional force is increased. Therefore, the sliders 26, 26 slide gently along the guide rails 16a, 16b.
