[specific embodiment]
Refer to Fig. 1, in a preferred embodiments of the present invention, a printer comprises an adjusting device.Described adjusting device, in order to adjust the distance between paper 100 to one ink-jet combinations 200, comprises a bearing 10, a power transmission shaft 20, two paper feed idle pulleys 30, a paper-feed 50 and a transmission combination 60.One side extension of described bearing 10 is provided with two fixed parts 11 and a location division 13.Described location division 13, between described two fixed parts 11, and forms one in order to accommodate the resettlement section 15 of described paper feed idle pulley 30 between the fixed part 11 adjacent with each.Each fixed part 11 comprises a roof 111, a diapire 112, a first side wall 113 and the second sidewall 114.Described roof 111, diapire 112, the first side wall 113 and the second sidewall 114 connect described bearing 10, and surround formation one receiving space 116.Described diapire 112 is offered a groove (not shown), in order to an elastic component 70 to be installed.Described the second sidewall 114 is offered the breach 1141 and the chute 1143 that are communicated with described receiving space 116.Described breach 1141 is communicated with described chute 41143.Described location division 13 comprises a link 131 and a positive stop end 133.Described link 131 connects described bearing 10, and described positive stop end 133 bends extension downwards from the top of described link 131, and and described link 131 between form a stopper slot 135.On described power transmission shaft 20, be fixed with described two paper feed idle pulleys 30.In one embodiment, the cross section of described power transmission shaft 20 and two paper feed idle pulleys 30 is circular.The diameter of described paper feed idle pulley 30 is greater than the diameter of described power transmission shaft 20.Described paper-feed 50 is in order to coordinate with described paper feed idle pulley 30, to transmit paper 100.In one embodiment, the cross section of described paper-feed 50 is circular.Described transmission combination 60 is in order to accept the paper 100 from described paper feed idle pulley 30 and paper-feed 50 transmissions, and comprises one first roller 61 and the second roller 63.In one embodiment, the cross section of described the first roller 61 and the second roller 63 is circular.The diameter of described the second roller 63 is greater than the diameter of described the first roller 61.Described ink-jet combination 200 comprises a print cartridge 201 and a nozzle 202 in order to ink-jet.
Please refer to Fig. 2-4, when assembling, described elastic component 70 is fixed in the groove of described diapire 112.Described two paper feed idle pulleys 30, respectively near described resettlement section 15, are stretched into described power transmission shaft 20 in the stopper slot 135 of described location division 13, and are housed in described chute 1143 along described breach 1141.The two ends of described power transmission shaft 20 are shelved on respectively on described elastic component 70.Described paper-feed 50 is fixed on the top of described two paper feed idle pulleys 30, and with described paper feed idle pulley 30 near together with or and described paper feed idle pulley 30 between leave gap.Described transmission combination 60 is fixed on a side of described bearing 10, described the first roller 61 near described the second roller 63 or and the second roller 63 between leave the gap that allows described paper 100 pass.When described ink-jet combination 200 is fixed on and works between described paper-feed 50 and described transmission combination 60, described paper 100 skids off between described two paper feed idle pulleys 30 and described paper-feed 50.
Refer to Fig. 2, in the time that described paper 100 is thinner, described paper 100 compresses described two paper feed idle pulleys 30, and the upper surface of described paper 100 and described paper-feed 50 tangent.Now, described elastic component 70 has a less deformation quantity.
Refer to Fig. 3, in the time that described paper 100 is thicker, described paper 100 compresses described two paper feed idle pulleys 30, and orders about described power transmission shaft 20 and move down along described chute 1143.What described elastic component 70 was subject to described power transmission shaft 20 compresses generation compression, and now, described elastic component 70 has larger deformation quantity, and the upper surface of described paper 100 and described paper-feed 50 tangent.Due to the invariant position of described nozzle 202 and described paper-feed 50, so described paper 100 is constant to the distance between described nozzle 202.The paper 100 sliding between described two paper feed idle pulleys 30 and described paper-feed 50 combines 200 belows from described ink-jet and slips over, and skids off between described transmission combination 60.When described paper 100 is during in described nozzle 202 below, described nozzle 202 is sprayed onto ink the upper surface of described paper 100, and described paper 100 is printed.
