Claim 2

A cartridge for containing and supplying developing powder in a copying machine, comprising: a casing having a first opening; a container for the developing powder mounted inside said casing, having a second opening and movable with respect to said casing from a position of containment of the developing powder to a position of discharge of the developing powder, in which the first and second openings are aligned and the developing powder is discharged through said opening; and, means for clamping said container in said second discharge position to prevent any subsequent movement of the container with respect to the casing starting from the discharge position.

Claim 3

In a copying machine of the electrophotographic type, the combination comprising: a cartridge for containing and supplying developing powder into the copying machine including: a casing having a first opening, a container for the developing powder mounted inside said casing, having a second opening and movable with respect to said casing from a position of containment of the developing powder to a position of discharge of the developing powder, in which the first and second openings are aligned and the powder is discharged through said openings, and means for clamping said container in said discharge position to prevent any subsequent movement of the container with respect to the casing, starting from the discharge position; means removably mounting said cartridge in the copying machine; first detecting means for detecting the movement of the container from the containment position to the discharge position; and enabling means, responsive to said first detecting means upon detection of said movement from the containment position to the discharge position, for enabling the copy operation of the machine.

Claim 4

In a copying machine of the electrophotographic type, the combination comprising: a cartridge for containing and supplying developing powder into the copying machine including: a casing having a first opening, a container for the developing powder mounted inside said casing, having a second opening and movable with respect to said casing from a position of containment of the developing powder to a position of discharge of the developing powder, in which the first and second openings are aligned and the powder is discharged through said openings, and means for clamping said container in said discharge position to prevent any subsequent movement of the container with respect to the casing, starting from the discharge position; means removably mounting said cartridge in the copying machine; first detecting means for detecting the movement of the container from the containment position to the discharge position; and enabling means, responsive to said first detecting means upon detection of said movement from the containment position to the discharge position, for enabling the copy operation of the machine.

Claim 5

In a copying machine according to claim 2 further comprising: second detecting means for detecting the correct positioning of the cartridge on said removably mounting means, said enabling means being also responsive to said second detecting means upon detection thereof, whereby the machine is enabled only when the cartridge is correctly positioned in the copying machine and the container has been moved in said discharge position.
