Embodiment
The utility model is with the relevant figure of following of detailed description, and it goes out to spread all over identical or corresponding part in several observations with figure denote.
The utility model is applied to be placed in the powder box of image forming device, and wherein perhaps image forming device is printer (photographic copyier), laser printer (1aser beamprinter), facsimile recorder (fax machine) or in conjunction with above any or all among both.Moreover this powder box comprises the device that forms the electron image processing procedure, and it can make what the non-user who is familiar with this technology used.This processing process comprises one or more hoppers from appointment to the position of developing, and a brush shape system system with magnetic makes developer and/or toner present potential image on photosensitive drums to transmit the developer of single or dual composition whereby.
Continue, see also shown in Figure 2ly, the utility model provides a stopping device 1 with protection photosensitive drums 2, its by a drum cover 10, at least one torsion spring 11, a button 12 and a stage clip 13 constituted.This drum cover 10 lateral plates 101 with two similar arcs, and the part 100 that is coupling has two sides to link two lateral plates 101 that distinctly are fixed on end, and cover plate 102 has integrant two lateral plates 101 at free-ended dual-side.One part 100 that is coupling has two axostylus axostyles 103 to give prominence at dual-side, so that each other part is attached in the toner collector shell 30 that has two axis holes 300 in the powder box 3 at least, cover plate 102 is used for the part of protecting photosensitive drums 2 to expose.
In addition, cover the lateral plate 101 of one of them in 10 at drum has a button portion 104 that is formed on inner surface, and button spring 11 is arranged in and is fixed in bulging the lid on the axostylus axostyle 103 of 10 ends.Button 12 is placed in the formed room 301 of toner collector shell 30 sides, and stage clip 13 is placed in the nose bar 120 that is arranged in button 12 inboards and be configured in position between the axle sleeve 302 on the room 301 of toner collector shell 30, and button 12 has an opening 121 that is arranged in the top and cover with drum that button portions 102 match in 10, so as can with rouse cover 10 and toner collector shell 30 be closely together.
For associative operation, see also Fig. 3, in press button 12 is pressed into the room 301 of toner collector shell 30 in the powder box 3, can passes through opening 121 in drum 10 the button portion 104 of cover, so can be fixed in the position of this press button 12 against stage clip 13 opposite elastic force at press button 12.See also Fig. 4, pressed in the room 301 of button 12 toner collector shell 30 in the powder box 3 again, it is separated from the opening 121 of press button 12 by the opposite elastic force of torsion spring 11 that drum covers 10 button portion 104.
In addition, drum cover 10 and is opened against manual operations or automated machine, and a laser beam makes it deflection with in the main accessory that enters powder box 3 by mirror, and passes through the window of an exposure in powder box 3, with the surface around the scanning photosensitive drums 2, it produces electric charge by charged roller.Therefore, drum covers 10 and can be taken as the switch that exposes window in powder box 3.
