Printing device

A printing device comprising:

• actuating means including:
• a printing head and the actuating means being movable for effecting imprinting of an imprintable medium by the printing head;
• a frame and the actuating means being supported on the frame;
• a counting device connected with the actuating means for counting the number of movements of the actuating means for thereby counting the number of imprints effected;
• the counting device comprises a shaft supported on the frame and comprises a plurality of rotary wheels mounted for rotation on the shaft, and the wheels being connected to rotate in response to actuation of the actuating means for counting actuations by rotating;
• a print stopping mechanism movable to a first position at which the print stopping mechanism permits the actuating means to move for effecting imprinting and movable to a second position at which the print stopping mechanism stops movement of the actuating means;
• the print stopping mechanism including operating means on one of the counting wheels for being moved by rotation of the respective counting wheel to a position which moves the print stopping mechanism to the second position of the print stopping mechanism after the counting device counts a certain number of movements of the actuating means;
• the stopping mechanism comprising a stopper rotatably mounted on the frame and rotatable between the first and second positions of the stopping mechanism;
• a retaining member on the frame and being engageable with the stopper for retaining the stopper in the first position thereof;
• biasing means for normally urging the stopper and the retaining member into engagement;
• the biasing means normally biasing the stopper to the second position, and the retaining member being positioned for normally preventing such biased motion of the stopper;
• the operating means being positioned to engage the retaining member and for moving the retaining member to release engagement with the stopper;
• the stopper having a circumference, one portion of the circumference being toothed and another portion of the circumference supporting and defining a protrusion extending outward from the rotation axis of the stopper;
• the retaining member being pivotally attached to the frame, and away from the pivot attachment of the retaining member, the retaining member including a hook for engaging the protrusion of the stopper;
• the biasing means bringing the protrusion of the stopper and the hook of the retaining member into engagement;
• the retaining member being provided with a further protrusion positioned for being engaged by the operating means upon completion of predetermined rotation of the counting wheels, and such engagement between the operating means and the retaining member protrusion serving to pivot the retaining member to separate the retaining member from the stopper;
• a print returning mechanism connected with the stopping mechanism for returning the stopping mechanism from the second position to the first position thereof.

• a print returning mechanism connected with the stopping mechanism for returning the stopping mechanism from the second position to the first position thereof;
• the returning mechanism engaging the stopper for rotating the stopper to the first position thereof as the returning mechanism is moved;
• the returning mechanism comprising a sliding member slidable with respect to the frame for rotating the stopper to the first position thereof;
• pinion means joining the sliding member and the stopper, such that sliding of the sliding member in one direction rotates the pinion means for rotating the stopper to the first position thereof at which there is reengagement of the stopper with the retaining member.
