Printer

A printing mechanism comprising:

• a. a base;
• b. a plurality of type wheels mounted on said base for rotation about a common first axis in axially juxtaposed relationship, each type wheel having a peripheral face and carrying type on said face thereof;
• c. a support movably mounted on said base;
• d. a printing roll shaft mounted on said support for rotation about a second axis extending in a common direction with said first axis;
• e. mounting means on said shaft;
• f. a plurality of printing rolls secured to said mounting means for rotation about respective third axes parallel to said second axis in angularly offset relationship,
• 1. said mounting means maintaining fixed, equal distances between said third axes and said second axis,
• 2. said printing rolls being axially offset from each other and radially aligned with respective ones of said type wheels,
• 3. each printing roll moving toward and away from an operative position contiguously adjacent the aligned type wheel during rotation of said shaft;
• g. yieldably resilient means biasing said support toward said type wheels;
• h. guide means for guiding a card into a printing position, pressure on respective opposite faces of said card being simultaneously exerted by one of said type wheels and the aligned printing roll in the operative position of said aligned printing roll when said card is in said printing position thereof;
• and
• i. drive means responsive to movement of said card into said printing position for rotating said shaft.
