An automatic vending machine having a front door with at least one opening. A translucent image carrier bears two or more images cut into information strips and arranged on the image carrier by an intercalation process. The image carrier is mounted behind an array of cylindrical lenses. At least one light source is disposed behind the image carrier. A relative, linearly reciprocating movement is produced between the array of lenses and the image carrier in a direction perpendicular to an axial extent of the lenses. In the course of the relative movement, the array of cylindrical lenses provides, in succession enlarged views of the images borne by the image carrier, thereby producing an animated effect.

1. An automatic vending machine having a front door, comprising; at least one opening in said front door; a translucent image carrier, bearing two or more images cut into information strips and arranged on said image carrier by an intercalation process, said image carrier being mounted behind an array of cylindrical lenses; at least one light source disposed behind said image carrier; and means for producing a relative, linearly reciprocating movement between said array of lenses and said image carrier in a direction perpendicular to an axial extent of said lenses; wherein, in the course of said relative movement, said array of cylindrical lenses provides, in succession enlarged views of the images borne by said image carrier, thereby producing an animal animated effect. 2. The vending machine as claimed in claim 1, wherein the means for imparting a linearly reciprocating movement comprises an electric motor fixedly mounted inside the door, said motor having a shaft carrying an eccentric, wherein the active part of said eccentric is seated in an elongated recess in a guide rail to which the image carrier is attached, thereby causing linear motion of said image carrier when said shaft of said motor rotates. 3. The vending machine as claimed in claim 2, wherein the rise of the eccentric equals the distance between two adjacent cylindrical lenses of the lens array. 4. The vending machine as claimed in claim 2 wherein the guide rail is provided with guide means restricting the movement of said guide rail to a linear movement in a direction substantially perpendicular to the axial of said cylindrical lenses. 5. The vending machine as claimed in claim 1, wherein, in order to reduce parallax apt to be produced by close-distance, wide-angle viewing, the height H of the images on said image carrier is stretched by a length AH beyond the height H of the point of incidence of the extreme viewing angle by an amount being a function of the viewing distance of said height H and of the focal length of the lenses of said lens array. 6. The vending machine as claimed in claim 1, wherein said panel of cylindrical lenses is convex, as seen from the outside. 7. The vending machine as claimed in claim 1, wherein said panel of cylindrical lenses is concave, as seen from the outside. 8. The vending machine as claimed in claim 1, wherein said panel of cylindrical lenses is substantially planar. 9. The vending machine as claimed in claim 1, wherein the cylindrical lenses of said array extend in a substantially horizontal direction. 10. The vending machine as claimed in claim 1, wherein the cylindrical lenses of said array extend in a substantially vertical direction.
