The ground member 40 is configured. The earth member 40 is housed in the housing recess 32 of the insertion leg 16 and is detachably attached by an attachment means such as a set screw 56. In this case, in particular, the bent pieces 46a and 46b of the branch pieces 44a and 44b of the ground member 40 are inserted into the open portions 36 of the insertion legs 16, and are locked to the partition pieces 34.

Further, as described later (see FIG. 1), the curved piece 52 a of the ground member 40 is used when the base member 12 is rotatably attached to the arm member 60 by the rotation shaft 54. In particular, it is arranged so as to contact the inner surface of one support piece 74 of the arm member 60. Therefore, the curved piece 52 a slides while contacting the inner surface of the support piece 74 with the rotation of the arm member 60.

In the present embodiment, the grounding member 40 is formed in a bent plate shape from a metal material or the like. However, the grounding member 40 may be a linear or string-like conductive material such as a metal material. And other shapes.

An arm member 60 is rotatably supported on the cam portion 14 of the base member 12 by a rotation shaft portion 54. The arm member 60 includes a rectangular plate-shaped arm plate 62 as shown in FIG. At one end in the length direction of the arm plate 62, for example, an L-shaped plate-shaped bent piece 64 is formed which extends at a right angle from the end to one main surface side of the arm plate 62. One side portion 64 a of the bent piece 64 is arranged so as to face the arm plate 62 in parallel.

Further, at one end and the other end in the width direction of the arm plate 62, for example, an L-shaped plate-shaped bent piece 66 extending at right angles from one end to one main surface side of the arm plate 62 is formed. One rectangular side portion 68 of the bent piece 66 has a plurality of mounting holes 68a at predetermined intervals in the length direction. For example, as shown in FIG. 6, the plurality of mounting holes 68a are for appropriately mounting the arm member 60 to the document pressing plate P of the copying machine.

The other rectangular side 70 of the bent piece 66 has a substantially L-shaped projecting piece 72. The protruding piece 72 is provided with a U-shaped slit 72 at the center of the side portion 70, and the length in the width direction of a portion surrounded by the slit 72 is adjusted to an appropriate size by a method such as cutting. Then, the protruding piece 72 is formed by bending the portion cut into an appropriate size substantially perpendicularly to the one main surface side of the arm plate 62. Further, rectangular support pieces 74 are formed at one ends of the one and other sides 70 in the length direction. Both support pieces 74 have an insertion hole 76 for inserting the rotation shaft 54.

The base member 12 described in detail above is rotatably supported between one and the other support pieces 74 of the arm member 60 described above. That is, the cam portion 14 is arranged between the one and the other support pieces 74 so that the insertion hole 22 of the cam body 20 and the insertion hole 76 of the support piece 74 communicate with each other. In this state, the rotating shaft 54 is inserted through the insertion hole 22 and the insertion hole 76, and the base member 12 is rotatably mounted on the arm member 60. In this case, a casing 80, which will be described later, is provided on the arm member 60 so as to contact the cam portion 14.

The casing 80 includes a casing body 82 having a substantially rectangular parallelepiped shape, and has, for example, two open portions 84 having an octagonal cross section as shown in FIGS. 3 and 4, for example. The two opening portions 84 are provided side by side.

A surface 86 of the casing body 82 opposite to the surface having the two open portions 84 is substantially semicircular in cross section from the center in the width direction on the surface 86 side and from one end to the other end in the length direction. Is formed. The bulging portion 88 has a concave portion 90 at the center in the length direction along the circumferential direction of the bulging portion 88.

Further, two projections 98 and 100 are provided on a surface 94 and a surface 96 which are continuous with both ends of the surface 86 of the casing main body 82 in the length direction at intervals in the width direction of the surfaces 94 and 96. Is formed. The protrusions 98 and 100 are formed to have a substantially rectangular cross section, and are formed from one end to the other in the length direction of the surfaces 94 and 96.

As shown in FIG. 4 and the like, each of the two open portions 84 of the casing body 82 accommodates a coil spring 102 such as a compression spring as an urging member. In this state, the casing 80 is housed inside the arm member 60. In this case, one end of the coil spring 102 set in the casing 80 abuts on the inner wall surface of one side 64 b of the bent piece 64 of the arm member 60, and the other end of the coil spring 102 has the bottom surface of the open portion 84 of the casing body 82. That is, it is arranged so as to abut on the inner surface of the surface 86 of the casing body 82.

As shown in FIG. 5, the casing 80 is mounted inside the arm member 60 such that the bulging portion 88 is displaced while being in contact with the cam surface 18 of the cam portion 14. Further, the cam portion 14 of the base member 12 is rotatably supported by the arm member 60 by the rotation shaft portion 54.

In the wing switch 10 of the present embodiment, as shown in FIG. 6, for example, the insertion leg portion 16 of the base member 12 is moved up and down by an insertion portion 120 provided at the rear end of the copying machine main body B. It can be inserted freely. The earth member 40 arranged on the insertion leg 16 is brought into contact with a relay piece 130 formed of, for example, a metal plate in the shape of a square. In this case, the relay piece 130 is engaged and arranged in the hole 120 a provided in the insertion portion 120. The relay piece 130 is arranged such that the bent portion 130 a is in contact with the ground member 40. One end of the relay piece 130 is arranged on the wall surface 120b near one end of the hole 120a, and the other end of the relay piece 130 is locked to the other end 20c of the hole 120a.

On the other hand, another relay piece 150 made of, for example, a metal material is provided on the inner wall surface (conductive portion) 140 made of a metal material at the rear end of the copying machine main body B. A ground terminal 160 is fixed and connected between the two relay pieces 130 and 150 by a fixing means such as a screw.

Next, the operating state of the wing switch 10 according to the present embodiment will be described with reference to FIGS. When the document pressing plate P of the copying machine is in an open state by the wing switch 10, the bulging portion 88 of the casing 80 is positioned at the starting point side of the cam surface 18 as shown by the imaginary line in FIG. One stop 24 is engaged. When the document pressing plate P is in the closed state, the lower part of the casing 80 (the lower part than the center in the width direction of the surface 86 of the casing main body 82) as shown by the solid line in FIG. Is engaged with the second stop portion 26 on the end point side of the cam surface 18, and the bulging portion 88 is locked by the convex strip 28 of the cam surface 18. However, in FIG. 5, since the weight of the document pressing plate P is added to the arm member 60, the bulging portion 88 and the convex strip 28 of the cam surface 18 are not in contact with each other.

The arm member 60 is urged in the opening and closing direction by the urging force of the coil spring 102. As the door opening angle of the arm member 60 increases, the distance between the rotation center of the rotation shaft portion 54 and the sliding points of the bulging portion 88 and the cam surface 18 decreases, so that the coil spring 102 extends. In this case, the casing 80 is displaced while sliding along the surface of the arm plate 62 of the arm member 60 toward the base member 12.

Conversely, as the door opening angle of the arm member 60 decreases, the distance between the center of rotation of the rotating shaft 54 and the sliding points of the bulging portion 88 and the cam surface 18 increases. Spring 102 compresses. In this case, the casing 80 is displaced while sliding along the surface of the arm plate 62 of the arm member 60 to the side opposite to the base member 12 side.

In the wing switch 10 of the present embodiment, when the arm member 60 is closed against the urging force of the coil spring 102, the arm member 60 is prevented from coming off the arm member 60. The one side portion 64a of the bent piece 64 of 60 and the protruding piece 72 act as a retaining function. In this case, the conventional technique employs a method in which a shaft body such as a pin is separately attached to the arm member, and thus has a problem that the number of parts increases.

On the other hand, in this embodiment, the casing 80 can be prevented from coming off without increasing the number of parts by the cooperation of the bent piece 64 and the protruding piece 72 formed integrally with the arm member 60. Becomes In this embodiment, it is particularly possible to prevent the protrusion piece 72 from coming off.

Further, in the wing switch 10 of this embodiment, even when copying a thick copy original such as a dictionary, it is not necessary to lengthen the ground wire G as shown in the conventional example of FIG. No. That is, in the wing switch 10 of the present embodiment, as shown in FIG. 6, the earth member 40 is disposed on the insertion leg 16 of the base member 12, and the earth member 40 is Since it is connected to the relay piece 150 on the copying machine main body B side by the ground terminal 160, it is not necessary to set the ground wire longer than necessary as in the conventional example shown in FIG. There is no danger of entanglement with the parts of the members.

Therefore, in the wing switch 10 of the present embodiment, the arrangement of the ground terminal 160 with the copying machine main body B and the connection process can be simplified. In addition, since the ground terminal 160 is not exposed outside the copying machine main body B and the document pressing plate 3, the appearance is good.
