Definitions

• the invention refers to a method for construction of boards, whereon the appearing representation (drawing, image, photograph etc.) or part thereof, appears successively and in motion (animation, motion picture), which is characterised by the fact that the so appeared representation (drawing, image, photograph etc.) is composed of parallel stripes (11) of small width, placed close to each other, each stripe containing a part of the total representation ( Figure 1), whilst the board consists of successive mechanical arrangements (21) ( Figure 2), on the one hand for the storing (in each mechanism) of a large number of stripes, each containing different type of contents (22), and on the other hand for the fast succession and representation of each one of the stored stripes at the corresponding location of the total representation, so that the fast succession of different stripes on successive positions on the board results to the fast succession of the representations (the contents of the total appearing stripes composes the overall representation), and if each representation contains a snapshot of a continuous motion, the fast succession of the representations (with the continuous succession of the composing stripes) generates to the viewer the impression of motion
• Lighted signs of various sizes consisting of illuminated pieces (pixels). Each piece is a light bulb. The succession of lighting on each piece generates the impression of image. The continuous succession of brightness of the pieces, generates the impression of motion. Those images are of low quality and only a schematic impression is generated. The colours or their tone cannot be reproduced.
• the representation is composed of a large number of narrow stripes. On each stripe, part of the image is represented. Thus, if the representation is a photograph, on each stripe, part of the photograph is represented.
• the stripes may be horizontal or vertical.
• each mechanism Behind each stripe, a mechanism is placed.
• the number of mechanisms provided is equal to the stripes composing the representation.
• the purpose of each mechanism is the fast succession of each stripe's representation. Practically, on the board surface the mechanism presents stripes of different representation at each time. In an embodiment, this is achieved by the rolling of a sheet, which is composed by successive stripes of different representations.
• each representation consists a snapshot of a continuous motion
• the representations succession generates to the viewer the impression of motion. If only one part of the stripes is changing subject, then the impression of motion is generated for part of the representation.
• the speed of the content change may alter creating different motion speeds. Actually, the speed is adjusted in order to coincide with the eye capturing ability and thus to create the sense of continuous motion by the succession of the snapshots of each representation.
• the present invention which is not similar to any state-of- the-art invention known for the generation of moving representations on boards, is suitable for applications not covered by the known state-of-the-art inventions.
• the characteristics of the invention also signifying its applications, are:
• the representation and the board are visible, being lit either by daylight or by a projector light during night time, in the same way as ordinary objects are visible by the eye. No special projection or lighting conditions are required, as in the television or cinematography.
• the board may be of any size (i.e. theoretically from a few square centimetres to several square metres). Therefore, the invention is recommended for representations visible from a long distance such as advertising boards, announcement boards, notification boards etc. In a small size, it is recommended for motion representation boards of small dimensions, motion games, small dimension boards etc.
• the speed of particular movable mechanical parts that is the stripes succession speed (and therefore the representations succession speed) varies. It is also possible that the motion is not continuous but stepwise according to the progress of each stripe.
• the invention provides the "storage" capability of a large number of representations . 6.
• the invention due to the capability of generating the impression of motion is recommended for the design and study of representations that require a motion analysis (such as engineering mechanisms, chorographies, cartoons etc.). For the subject use, the ability of replaying the motion, either forward or reverse, is particularly useful.
• the representations have the natural colours (e.g. of the photographs or paintings) and are recommended for presentation of slides, portraits, natural images etc., that require a lifelike presentation such as advertisements, touristic matters, decorations of theatrical plays, representations of natural environment, wall lining (instead of a tapestry) etc.
• the board is composed of mechanisms, as in Figure 4.
• the representation appears on the front of the board (41).
• the stripes (47) of the sheets appear on the front side of the beams (42) and are imprinted on the sheets (43) which unwind and rotate by means of cylinders (44) in coordination with the mechanisms (45).
• the mechanisms (45) consist of the combination of screw (46) and gears (45) which are mounted on each unwinding drum (44).
• the screw is driven by a motor of constant revolutions for the simultaneous drum rotation and the succession of representations.
• a gear (51) is moounted, which collaborates with the respective gear of the next drum.
• the system rotates in absolute synchronisation.
• a sprocket (61) is mounted at the edge of each drum, whilst all the drums rotate by means of a chain which drives all the sprockets.
• the stripes ' material is preferably synthetic with low coefficient of friction when sliding on the beams (62).
• materials like paper, textile etc. may be used.
• paper with a transparent synthetic stripe lining is used (Figure 7).
• material with "hairy" surface is used for the sheets, so that the fibers of two stripes placed at the front side of the board and belonging to two adjacent sheets are tangled, thus preventing the discontinuity of the representation between stripes.
• cylinders drums
• the surface of the board is formed by the outer half of the surface of the cylinders.
