In a copying machine a copy-receiving device is provided which includes a table with a plate inclined to a horizontal at a predetermined angle and supporting thereon sets of copies or sheets to be stapled together by a stapling device which is insertable into the copy-receiving device and arranged at the lower end of the inclined plate. The stapling device is actuated by a drive motor, a crank drive with a pulling bar having an end portion with a compression spring thereon, and an actuating arm pivotally connected to the end portion of the pulling bar. The spring compensates for various thickness is of the stacks of sheets being stapled and provides for displacement-free stapling of the sheets.

An apparatus for squaring, stapling, and stacking copies is used in combination with a copier that produces a succession of sheet copies and has a housing adapted to be positioned adjacent the copier, an upper support plate in the housing positioned to receive the copies from the copier and having a downstream end remote from the copier, and a stop flap at the downstream end and pivotal between a position blocking copies from sliding down off the downstream end and a freeing position permitting copies to slide down off the downstream end. A downwardly inclined lower support plate in the housing below the downstream end of the upper plate is positioned to receive copies sliding in the freeing position of the stop flap off the downstream end of the upper plate. A stapler is fixed in the housing adjacent the upper plate upstream of the downstream end thereof and an actuator is connected to the stapler for closing same on a stack of copies on the upper plate for stapling same together. A controller is connected to the stop flap and the stapler actuator for periodically stapling the copies on the upper plate together and thereafter pivoting the stop into the freeing position to slide the stapled-together copies onto the lower plate.

Apparatus for squaring, stapling, and stacking copy sets

A developer device of an electrostatic copier has a housing provided with an upper opening for admission of toner. A toner supply container has an open side and cooperating parts on the container and housing seive to mount the container on the housing with the open side of the container facing downwardly into the opening so that toner runs from the container into the housing. A slidable closure member on the container can be moved to and fro across the open side to block and unblock the same at the will of a user.

Tuner supply for electrostatic copiers

A cleaning device for an electrostatic copier of the type having an endless travelling charge carrier provided with a photosensitive surface which is electrostatically chargeable to form a latent image to which toner particles are attracted for subsequent transfer to an image carrier. The cleaning arrangement removes residual toner particles from the surface prior to the next electrostatic charging thereof and is in form of a cleaning cartridge that can be inserted into and removed from the copier in toto. The cartridge has a leading open end and instrumentalities at this end which engage the photosensitive surface of the charge carrier when the cartridge is inserted into the copier. Elastically deformable sealing elements are provided on the cartridge and at least in part bound the open end thereof, yieldingly engaging the photosensitive surface in response to the insertion of the cartridge into the copier.
