In addition, elastic pieces 74 and 74 that protrude toward the rear end portion of the insertion hole 73a and are elastically deformable by being compressed toward the front end portion are formed at the front end portion of the insertion hole 73a. When the shaft portion 50a of the rotation pin 50 is inserted into the insertion holes 73a and 73a, the second conductive plate 71 is rotated by elastically deforming toward the front end side of the elastic pieces 74 and 74 by the shaft portion 50a. It contacts the moving pin 50.

  By configuring the hinge 10 according to the present embodiment as described above, the main body 2 and the original cover 3 can be electrically connected via the first conductive plate 61, the rotation pin 50, and the second conductive plate 71. it can. Specifically, as shown in FIG. 4, the first conductive plate 61, the rotation pin 50, and the second conductive plate 71 are in contact with each other, so that the first conductive plate 61, the rotation pin 50, The second conductive plate 71 is electrically connected.

Electrically connected. Thereby, the main body 2 and the original cover 3 are electrically connected, and an electrical ground connection can be secured between the main body 2 and the original cover 3.

  By configuring the hinge 10 according to this embodiment as described above, even when the case 20 and the cam block 40 are formed of insulating resin members, it is not necessary to separately connect conductive members such as conductive wires. That is, the first conductive plate 61 is assembled to the case 20 in advance, and the second conductive plate 71 is assembled to the cam block 40, so that the hinge 10 can be electrically conductive only by assembling the cam block 40 to the case 20. Thus, the main body 2 and the original cover 3 can be grounded. That is, after assembling the cam block 40 to the case 20, it is not necessary to assemble a conductive member such as a conductive wire and a conductive mating part, thereby improving work efficiency when the hinge 10 is attached to the office equipment. Is possible.

  Further, the first conductive plate 61 can be easily disposed by being inserted into the insertion hole 20 b of the case 20.

That is, the first conductive plate 61 and the second conductive plate 71 can be easily disposed on the case 20 and the cam block 40 without using a special tool or the like. The efficiency can be further improved.

  Furthermore, according to the hinge 10 according to the present embodiment, since the first conductive plate 61 and the second conductive plate 71 are disposed along the surfaces of the case 20 and the cam block 40, the dimensions of the hinge 10 are large. The hinge 10 can be configured compactly.

  In addition, in the hinge 10 according to the present embodiment, the first conductive plate 61 and the second conductive plate 71 are formed with elastic pieces 62 and 74 that are elastically deformable at one end portions of the insertion holes 61a and 73a. . When the shaft portion 50a of the rotation pin 50 is inserted into the insertion holes 61a and 73a, the elastic pieces 62 and 74 are elastically deformed by the shaft portion 50a, whereby the first conductive plate 61 and the second conductive plate 71 are moved. The rotating pin 50 is configured to abut. Thereby, even if the cam block 40 rotates with respect to the case 20, the first conductive plate 61 and the second conductive plate 71 are always turned to the rotation pin 50 by the elastic force (spring property) of the elastic pieces 62 and 74. It becomes possible to make it contact | abut. That is, it is possible to prevent an electrical contact failure between the main body 2 and the original cover 3.

  As shown in FIGS. 7 and 8, the slider accommodating chamber 21 accommodates a slider 31 and a winding spring 33 that is an urging member. As shown in FIG. 9, the slider 31 is configured to be movable in the up and down direction, which is a direction approaching and separating from the cam block 40. Specifically, the slider 31 is formed in substantially the same shape as the slider accommodating chamber 21 in plan view, so that the inside of the slider accommodating chamber 21 can be slid up and down. On the upper surface of the slider 31, a cam receiving portion 31 a having a curved shape protruding upward is formed at a portion facing the slider cam 41 of the cam block 40. A spring receiving hole 31 b into which the upper end portion of the winding spring 33 can be inserted is formed on the lower surface of the slider 31.

  The winding spring 33 biases the slider 31 upward, which is a direction approaching the cam block 40. Specifically, the upper end of the winding spring 33 is inserted into the spring receiving hole 31 b of the slider 31 and the lower end is in contact with the bottom surface of the slider accommodating chamber 21. In other words, the winding spring 33 is interposed between the slider 31 and the bottom surface of the slider accommodating chamber 21. That is, the slider 31 is biased upward by the elastic force when the winding spring 33 is compressed. Accordingly, as shown in FIG. 6, the winding spring 33 causes the cam receiving portion 31 a of the slider 31 to contact the slider cam 41 and rotates the cam block 40 in the opening direction with respect to the case 20 (with respect to the cam block 40). Thus, a torque for rotating about the rotation pin 50 is applied).

  As shown in FIGS. 2 to 9, a pin member 25 is inserted into the slider accommodating chamber 21 from the rear of the case 20 on the upper rear surface of the case 20. The pin member 25 does not affect the sliding of the slider 31 during normal use of the hinge 10, and prevents the slider 31 from being detached from the slider accommodating chamber 21 when the cam block 40 is detached. It is a member.

  The action of the pin member 25 will be specifically described with reference to FIG. A notch 31 c is formed on the upper rear surface of the slider 31. In a normal use state of the hinge 10, even when the hinge 10 is opened as shown in the right diagram of FIG. 9, the protruding portion of the pin member 25 into the slider accommodating chamber 21 is located inside the notch 31c. The pin member 25 does not come into contact with the slider 31. If the cam block 40 is detached from the case 20, the notch 31 c of the slider 31 comes into contact with the pin member 25 protruding into the slider accommodating chamber 21. Thereby, it is possible to prevent the slider 31 and the winding spring 33 from jumping out of the slider accommodating chamber 21 and being detached.

  As shown in FIGS. 7 and 8, the damper housing chamber 22 houses a damper 32 that generates a reaction force when the upper end portion receives a pressing force by a damper cam 42. The damper 32 is a general fluid damper. When the main body of the damper 32 is fixed at a predetermined position inside the damper housing chamber 22 and the piston 32a is pressed downward, the reaction force (push the piston 32a back upward). Force) is generated. For this reason, the speed at which the piston 32a moves downward by the reaction force is reduced (a buffering effect by the damper 32 is generated).

  As shown in FIG. 10, a bottomed cylindrical sliding member 36 having an opening on the lower side is disposed above the damper 32 inside the damper housing chamber 22 so as to be movable up and down in the damper housing chamber 22. . Specifically, the sliding member 36 is formed in substantially the same shape as the damper accommodating chamber 22 in plan view, so that the inside of the damper accommodating chamber 22 can be slid up and down. A flat contact surface 36 a is formed on the upper portion of the sliding member 36 at a portion facing the damper cam 42 of the cam block 40.

  The winding spring 34 biases the sliding member 36 upward, which is a direction approaching the cam block 40. Specifically, the winding spring 34 is interposed between a lower end portion of the sliding member 36 and a seat surface 32b formed to protrude radially outward from the outer peripheral surface of the damper 32 at the lower portion of the damper 32. Yes. That is, the sliding member 36 is urged upward by the elastic force when the winding spring 34 is compressed. As a result, as shown in FIG. 7, the winding spring 34 abuts the abutment surface 36 a of the sliding member 36 against the cam block 40.

  The damper cam 42 of the cam block 40 is formed in a cam shape so that the upper end portion of the damper 32 receives a pressing force by the damper cam 42. In the present embodiment, when the document crimping plate 3 is rotated by the user of the multifunction machine 1, the inner bottom surface of the sliding member 36 and the piston 32 a of the damper 32 are in contact with each other. That is, since the upper end portion of the damper 32 receives a pressing force by the damper cam 42, a buffering effect by the damper 32 occurs.

  As shown in FIGS. 2 to 8 and 10, a pin member 26 is inserted into the damper housing chamber 22 from the rear of the case 20 on the upper rear surface of the case 20. The pin member 26 is a member for preventing the sliding member 36 from being detached from the damper accommodating chamber 22. Specifically, when the hinge 10 is opened as shown in the right diagram of FIG. 7, the upper surface of the sliding member 36 comes into contact with the pin member 26 protruding into the damper accommodating chamber 22. As a result, the sliding member 36 and the winding spring 34 can be prevented from jumping out of the damper accommodating chamber 22 and being detached.
