A hand-held printer in which tickets or the like are fed between a platen and an indicia-bearing printing wheel carried by a printing head. The platen is rotatable on a base on which the carrier is slidable vertically between an upper position in which the platen and wheel are spaced apart to receive the ticket therebetween and a down position in which the wheel presses the ticket against the platen. The printing wheel is inked by an associated inking wheel. Vertical movement of the carrier relative to the base is achieved manually by the gripping of elements located on the base and carrier. The printing head is selectively positionable crosswise of the platen to accommodate varying locations on the ticket to be printed. An adjustable ticket guide is provided to enable guiding of tickets of different dimensions.

A dual modular device for the display and dispensing of tickets is provided that includes a box type unit with two storage sections and a rear door that is pivotally mounted by a mounting assembly formed of cylindrical posts attached to each lower corner of the door and receivably journaled in cavities located in the lower rear portion of each sidewall of the unit. The door further includes side and top flanges that overlie the sidewalls and roof of the unit when the door is in a closed position to secure the sidewalls of the unit from being forced apart to gain access to the interior of the unit. The lower portion of the door also includes offset side edges to provide a door with approximately the same dimension as the inside measurement between the two sidewalls of the unit so that the lower portion of the door acts as a positioning guide when closing the door.

A structure for the display and dispensing of tickets whereby top and bottom units are demountably attachable in a stackable arrangement. Each unit is of box-like configuration having a floor, a roof, a pair of sidewalls and an open rear end. A door is pivotally attached at a lower portion of the rear end and semi-permanently attachable in an opposite upper portion of the rear end of the unit to serve as a rear wall for the unit when in a closed position. The bottom unit has a front flange on the bottom portion of the front wall extending downward and rearward into a cavity in the top portion of the front wall to provide a forwardly extending lip portion engageable by the front flange of the top unit when the units are in a stacked relationship. The top unit also has a rear flange on its lower rear portion that extends through at least one opening in the roof of the bottom unit. The rear flange extends downwardly and rearwardly such that it may be engaged by a forwardly extending flange on the upper end of the door of the top unit when such door is in a closed position to lock the two units together in a semi-permanent relationship.

The ticket display and dispenser is a box forming one or more compartments for containing one or more ticket chains made up of a plurality of end-to-end or side-to-side interconnected tickets arranged in series-connected fashion. Each chain of tickets is fed forwardly through a ticket-entry slot for upward travel over a display structure and then rearwardly through a ticket-re-entry slot for exit through a ticket-exit slot at the rear of the box. The open front of the box is closed by a transparent cover that overlies the display structure and tickets displayed thereon. The ticket exit is located at the rear of the apparatus and the cover is lockable in place to prevent unauthorized access to the tickets, usually of the lottery type.

The disclosed ticket dispenser is especially designed for the dispensing of series-connected lottery tickets and provides a box-like structure for containing the tickets which are exited through a slot in one of the structure walls. The structure is configured so as to provide guide and ticket-tensioning elements about the slot and further includes wings closing the slot at opposite edges. The wall of the structure in which the slot is provided is hinged to the rest of the structure and has a lockable catch releasable to afford access to the interior of the structure. Portions of the structure are shaped in such fashion as to prevent or minimize interior obstructions to the free travel of tickets via manual tensioning forces applies exteriorly of the structure.

A storage, display and dispensing apparatus for tickets of various sizes that accounts for the tickets dispensed during a selected time period. The dispensing apparatus includes a bin housing for storing a pack of tickets, a ticket dispensing assembly through which the tickets are dispensed and includes a friction wheel assembly that is actuated as tickets passed through the tear bar assembly so that a count of such tickets is provided. A piezo electric sensing element is also employed to sense perforations between the tickets and to reset the friction wheel assembly count as a result thereof.
