Title: Burster
Inventor: AMANO TAKASHI
IPC: B26F3/02
Filed: 1985-03-19
Abstract: PURPOSE:To cut easily and reliably, in a burster for business machine, by utilizing the perforation interval of form to indicate the regulation of speed controller for regulating the circumferential speed of paper feed roller and paper discharge roller. CONSTITUTION:The brake body 29 is set with reference to the paper discharge rollers 23, 24 with correspondence to the interval of perforation of single form 12. While the dial 35 of a speed controller 33 is matched with the indication of form length 36 thus to set the circumferential speed of the paper feed rollers 17, 18 and the paper discharge rollers 23, 24. The form 12 between the guideboards 20 is fed through the paper feed rollers 17, 18 below the brake body 29 then while applying the tensile force onto the form 12 through the paper discharge rollers 23, 24 having higher circumferential speed, collides against the projected outer end of the brake body 29 to be cut instantaneously along the perforation and stacked on a receiving table 25. Here, the form 12 is cut reliably because it will pass to the paper discharge roller with longer time than that required for the brake body 29 from start and finish of cutting.

SOLUTION: In a state where the toner of the toner cartridge 60 is deficient, operations except an auger 15 and a magnet roller 61 are stopped and magnetic toner 64 having a high additive concn. in a developing unit 4 is recovered into the cartridge 60. After a new toner cartridge 61 is attached, the auger 15 and the magnet roller 61 are driven for a specified time and the magnetic toner 64 having the high additive concn., remaining in the developing unit 4 is recovered into the cartridge 60 and stirred, to prevent reduction in image density caused by the concn. of the additive of the magnetic toner 64 of the developing unit 4, increased by the exchange of the cartridge 60 and further, the reduction in the image density just after the exchange of the cartridge 60. Therefore, an image can be always formed with a stable density.  Moreover, a recovering port 60b is outside an effective image width, so that the image density is not directly affected by the recovery state of the toner. Thus, the image is formed with a stable image density.
