Embodiment
Below, describe the embodiment of the opening and closing device of manuscript press plate of the present invention in detail with reference to accompanying drawing.
In the accompanying drawing 1, label P is a manuscript press plate, can be installed on the apparatus main body M of duplicating machine through opening and closing device H with opening and closing, and above-mentioned opening and closing device H mainly is made up of following each member: be installed on the installation component 1 on the said apparatus main body M; Be hubbed at the supporting arm 3 on this installation component 1 rotationally through hinge axis 2; Be hubbed at this supporting arm 3 front ends rotationally through bolster 4, install, fix the lifting arm 5 of above-mentioned manuscript press plate P simultaneously.
In the above-mentioned supporting arm 3; Hold the 1st saddle 6 and the 2nd saddle 7 slidably along its length direction; Through inserting compression helical spring 87 of the 1st saddle the 6, the 2nd saddles, compression helical spring 8 is double-helix springs in the present embodiment, but is not limited thereto simultaneously.The protruding car driven member 7a of above-mentioned the 2nd saddle 7 is contacted with the cam part 9 that is arranged on above-mentioned installation component 1.
In addition, opening and closing device H of the present invention is not limited to above-mentioned structure, for example omits bolster 4 and lifting arm 5, and above-mentioned manuscript press plate P is installed, is fixed in the structure of supporting arm 3 etc., and well-known in the past any structure gets final product.
Above-mentioned piston rod 10b is contained among the said cylinder 10a slidably, is formed with the 1st 10d of fluid chamber in the side of piston rod 10b, and is formed with the 2nd 10e of fluid chamber at opposite side, along with the volume that moves those fluid chamber of piston rod 10b changes.
Be formed with fluid passage 10b ' among the above-mentioned piston rod 10b; Along with moving of piston rod 10b; Make the viscous fluid (for example silicone oil) in the 1st 10d of fluid chamber move to the 2nd 10e of fluid chamber, and make the fluid in the 2nd 10e of fluid chamber move to the 1st 10d of fluid chamber on the contrary, above-mentioned flow adjustment is with the mobile flow of needle-valve 10f adjustment fluid; To reach the absorption energy power of fluid buffer 10, the flow adjustment can be from being arranged in the hole adjustment of contact system 10c front with needle-valve 10f.
Opening and closing device of the present invention such as above-mentioned formation; Therefore start manuscript press plate P; Make it close to state shown in the 3rd figure from state shown in the 1st figure; Then the weight of manuscript press plate P is greater than the lifting force of compression helical spring 8, and when just descending suddenly, the front end of the contact system 10c of above-mentioned fluid buffer 10 just is contacted with above-mentioned the 2nd saddle.
