Snubber assembly 8 is set in compression helical spring 73 sometimes.This snubber assembly 8 makes manuscript press board 3 when closing direction rotates, only in (below for example about 10 °) time, move below manuscript press board 3 is in as the special angle below the open angle of predetermined rotational angle, so that the velocity of rotation of manuscript press board 3 reduces.In addition, closing direction of the present invention is meant that manuscript press board 3 is near the direction of contact glass 20 when manuscript press board 3 is rotated.Following so long as the angle that described predetermined open angle is following of special angle of the present invention gets final product, and is not particularly limited.
Snubber assembly 8 for example is a hydraulic shock absorber etc.As long as this snubber assembly 8 can only move when manuscript press board 3 is in (below for example about 10 °) below the special angle, to reduce the opening and closing speed of manuscript press board 3, then there is no particular limitation.The for example main hydraulic cylinder 81 of snubber assembly 8 by fluid such as filling silicon oils, and piston (not shown) constitutes, this piston is arranged in the hydraulic cylinder 81 movably, is connected with piston rod 83, and is endowed potential energy so that piston rod 83 is elongated from the length that hydraulic cylinder 81 exposes.
Owing to being, therefore particularly useful when assembling in order to prevent that cam slide parts 72 from stopping up joint pin mounting hole 17 because of the elastic force effect of volute spring 73 by compression and being provided with backstop hole 9.The position in backstop hole 9, as long as between the free end and joint pin mounting hole 17 of support component 5, and be not particularly limited, so long as when the joint pin mounting hole 17 to the connecting hole 16 of installing component 4 and support component 5 cooperates alignment, the end face butt that makes cam slide parts 72 is subjected to pad 13 and the position that do not counteract gets final product, and there is no particular limitation.That is, in this backstop hole 9, insert for example pin 10, by making cam slide parts 72 and these pin 10 butts, and can prevent that cam slide parts 72 from stopping up joint pin mounting holes 17 as backstopping assembly.Its result, make the aliging cooperating of dead eye 45,45 of parts of bearings 44,44 on joint pin mounting hole 17,17 and the connecting hole 16,16 that is installed in installing component 4 of support component 5, and the operation of packing into of packing ring 46,46, also have the logical operation of inserting of first joint pin 11 to be easy to carry out, improved assembling operation efficient.At this moment, be subjected to pad 13 in advance pedestal be fixed between the biside plate 42,42 of installing component 4, also can be after connecting install again by first joint pin 11.
The raising of relevant this packaging efficiency uses Fig. 1～Fig. 5 to be elaborated.When the device for opening and closing manuscript crimping plate that assembling the present invention relates to, as shown in Figure 1, at first make and in the action pin-and-hole, insert logical action pin 14, and the second joint pin inserting hole of the lifting piece 6 that is fixed cooperates with second hinge pin aperture 57 of support component 5 and aligns.Cooperate slotting logical second joint pin 12 in the hole of aliging at this, making lifting piece 6 serves as that axle is connected each other rotationally with support component 5 with second joint pin 12.Certainly, this assembling operation also can carry out conversely.
Then, the spring bearing part 71 and the compression helical spring 73 of snubber assembly 8 will be installed from base end part (ends of the joint pin mounting hole 17 sides) side of support component 5, be coated with thereon under the state of cam slide parts 72, insert together in the resettlement section 58 of support component 5.Like this, spring bearing part 71 and action pin 14 butts, as shown in Figure 2, because be in the state that cam slide parts 72 stop up the joint pin mounting hole 17 of support component 5, therefore, overcome the elastic force of compression helical spring 73 with not shown anchor clamps pushing cam slide parts 72, when the end face that makes these cam slide parts 72 passes through backstop hole 9, as shown in Figure 3, pin 10 is inserted in the backstop holes 9, make cam slide parts 72 butt pins 10 and stop in this position.Avoid stopping up joint pin mounting hole 17 thus, thereby make the installation exercise of parts of bearings 44,44 on the connecting hole 16,16 of installing component 4, the operation of aliging that cooperates with the joint pin mounting hole 17,17 of the dead eye 45,45 of this parts of bearings 44,44 and support component 5, and the operation of packing into of packing ring 46,46 is easy to carry out, make first joint pin 11 pass joint pin mounting hole 17,17 and dead eye 45,45, support component 5 is connected on the installing component 4.In addition, be subjected to pad 13 in advance pedestal be fixed between the biside plate 42,42 of installing component 4.Then, when extracting pin 10, cam slide parts 72 be subjected to pad 13 butts, finish assembling operation.This state such as Fig. 5 and shown in Figure 7.
When particularly manuscript press board 3 is provided with master copy automatic conveying device, because the weight of manuscript press board 3 increases, compression helical spring 73 need have stronger elastic force, therefore the pushing to cam slide parts 72 also needs bigger power when assembling, is difficult to cooperate the logical operation of inserting of the alignment and first joint pin 11.Relative therewith, in the present invention, because cam slide parts 72 and pin 10 butts, joint pin mounting hole 17 always is in open state, so is easy to carry out joint pin mounting hole 17,17 and aligns the cooperating of dead eye 45,45 of parts of bearings 44,44, and inserting of first joint pin 11 behind the packing ring 46,46 of packing into led to operation.Its result is easy to support component 5 is installed on the installing component 4, can improve assembly operation.
In addition, in the present invention, cam slide parts 72 form, for example, pin abutting part 72f is in more than or equal to predetermined rotational angular when (also claiming first rotational angle) and first joint pin, 11 butts at manuscript press board 3 or support component 5, when be in than the big angle place of first rotational angle not be subjected to pad 13 butts.First rotational angle among the present invention is the angle than 90 ° of little predetermined angulars of maximum open angle, for example, and than little about about 25 ° to the 35 ° angle of maximum open angle (also claiming predetermined open angle).Like this, when manuscript press board 3 surpasses first rotational angle, cam slide parts 72 and first joint pin, 11 butts, cam slide parts 72 leave and are subjected to pad 13 then, make manuscript press board not be subjected to the elastic force effect of elastic device 7.
That is, manuscript press board 3 under the state that does not use equipment body 2, as shown in Figure 6, is close on the contact glass 20 of equipment body 2.In order on the surface of contact glass 20, to place original copy, at first to control the end of position opposite one side that is arranged on and is provided with lifting piece 6 on the manuscript press board 3 or near the handle part it etc., manuscript press board 3 is lifted upward.That is, making manuscript press board 3 serves as that axle rotates with first joint pin 11 only, and the surface of contact glass 20 is exposed to the outside.Like this, when manuscript press board 3 was rotated, manuscript press board 3 was given rotation potential energy because of volute spring 73 elastic force effects by compression to opening direction, therefore in imperceptible its weight when opening the direction rotation.
At this moment, as shown in Figure 7, when manuscript press board 3 is in first rotational angle, cam slide parts 72 and first joint pin, 11 butts, cam slide parts 72 leave (for example shown in Figure 8) from being subjected to pad 13 then, and therefore, the elastic force of 73 pairs of manuscript press boards 3 of compression helical spring is disengaged, make manuscript press board 3 velocities of rotation slow down and stop, thereby avoid manuscript press board 3 sharply to upspring.Its result, impact in the time of can not stopping because of manuscript press board 3 makes the fault of office equipment such as duplicating machine, and, even device for opening and closing manuscript crimping plate 1 has auto document feeder, can the impact when stopping not cause the fault of auto document feeder or make damages such as manuscript press board yet.
After placing original copy on the surface of the contact glass 20 that exposes, put down the manuscript press board 3 that is lifted.That is, manuscript press board 3 is rotated to closing direction.Like this, manuscript press board 3 is an axle with first joint pin 11, towards rotating (moving) downwards with the direction that contacts glass 20 contacts.At this moment, elastic force by compression helical spring 73, keeping the upper plate 61 of lifting piece 6 and the state of the top butt of adjusting screw 59a, promptly, keeping making manuscript press board 3 (lifting piece 6) can not serve as the state that axle rotates with second joint pin 12, and making manuscript press board 3 serves as that axially rotate the below with first joint pin 11 only.
Like this, make manuscript press board 3 when closing direction rotates, need little force for the elastic force that overcomes compression helical spring 73 at first, but, for example, when the open angle of manuscript press board 3 is following 20 ° (comprising about 20 °),, manuscript press board 3 is rotated to falling direction because the elastic force of the weight ratio compression helical spring 73 of manuscript press board 3 is big.When the open angle of manuscript press board 3 is special angle for example 10 ° (comprising about 10 °), the inner face 72d of the bottom of the top butt cam slide parts 72 of the piston rod 83 of snubber assembly 8, piston rod 83 is moved in hydraulic cylinder 81, the exposed length of piston rod 83 reduces, and the velocity of rotation of manuscript press board 3 is lowered.Its result, owing to control the velocity of rotation of manuscript press boards 3 by snubber assembly 8, so can avoid the advantage of manuscript press board 3 butt joint contact glass 20 to impact.
Then, when when contact glass 20 is taken original copy away and is made manuscript press board 3 get back to the origin-location, the action pin 14 that is installed in illustrated example on the lifting piece 6 that clockwise direction opens and closes slides and moves at the outside surface of spring bearing part 71, thereby be easy to carry out clockwise switching, manuscript press board 3 is easy to get back to the origin-location, and its operability is improved.
Therefore, the device for opening and closing manuscript crimping plate 1 that the present invention relates to has improved packaging efficiency, and has avoided sharply upspringing of manuscript press board 3, is easy to make the manuscript press board 3 of counter-rotating to get back to the origin-location.
In addition, though showed the scheme of using snubber assembly 8 in the above embodiment,, also can keep intact and be used for the device for opening and closing manuscript crimping plate that does not use snubber assembly 8.
As mentioned above, the device for opening and closing manuscript crimping plate that the present invention relates to, particularly in having used the device that makes the cam slide parts that elastic device plays a role, the time be easy to the cooperation alignment of the dead eye that carries out the joint pin mounting hole of support component and be installed in the parts of bearings on the installing component connecting hole in assembling, and first joint pin insert logical, on the basis that makes assembling be easy to carry out, when manuscript press board is opened, can avoid bringing impact for duplicating machine or master copy automatic conveying device, therefore for duplicating machine because of the bump of closing of this manuscript press board, printer, facsimile recorder, the device for opening and closing manuscript crimping plate particularly suitable of office equipment such as scanner.
