A hand held applicator for transferring pressure transferable graphic images from an accepting tape to a receptor surface. The applicator comprises a body having a bottom surface and a back surface intersecting the bottom surface to define a sharp separating edge, and a roller rotatably mounted on the front portion of the body with its axis of rotation in parallel alignment with the separating edge. The outer periphery of the roller projects out from the bottom surface so that as the applicator ...

A method and apparatus are provided for classifying areas on a raster-type display unit. The problem is to identify areas defined by a closed boundary--e.g. for filling in such areas. Boundary data are entered into a first "polygon" store which has a plurality of memory locations each corresponding to a respective dot position of the display field, and at least one seed point is identified. Each dot position is then examined to see whether there exists a connected path, not including a boundary ...

A graphic scanning and printing device comprising a scanning element having a plurality of metal bars arranged in series inclined at 10.degree. and movable into engagement with a graphic sign to be reproduced, written in electrically conductive ink, to produce an electrical pulse fed to a solenoid whose core bar prints a dot, through an ink ribbon or the like, the several core bars arranged in the same fashion as said scanning metal bars producing an exact reproduction of the graphic sign.

An interactive graphic system is provided which introduces drawing data step by step in the form of interaction to describe figures, characters, numerical figures or the like with the aid of a microcomputer. The interactive graphic system consists of a keyboard for introducing drawing data, a plotter for recording the figures, a microcomputer, and a memory unit that are constructed as a unitary structure which features small size, reduced cost and enhanced operational performance. Further, the i...

An interactive graphic system is provided for automatically recording lines, symbols or marks by inputting plotting information in a step-by-step mode in an interactive system. The systems comprise a data setter for specifying, among various predetermined graphs, a graph to be plotted and for setting plotting data concerning the graph thus specified, a plotter for providing records in association with input signals, a display for requiring the plotting data inputs, and a controller for suitably ...

Bitmapped graphics, font and vector form figure are transformed to gradation value respectively by zooming means (1), font representing means (2) and vector representing means (3). They are inputted to figure conserving gradation pixel data generating means (11), where average gradation value of plural gradation values is made and each of bits is given to each of plural gradation values. These bits represent the figure of graphics. So, they are called figure bits or figure data. With appending t...

A graphic recording system for use with a multiple channel underwater sonar system. The recording system includes a plurality of memories, each for storing information received over a different channel of the sonar system. One or more channels may carry side scan sonar information, while another may carry sub-bottom sonar information, etc. The information from the channels is received and stored in the memories simultaneously. The recording system further includes a graphic line recorder which i...

In a device for graphically representing characters encoded in a digital nal, a writing element adapted to sweep across a recording medium at selected intervals is enabled by a timing means to selectively mark the recording medium during a selected series of sweeps, and a decoding means receives the digital signal and provides segment select signals, which specify a combination of segments from a group of segments which may graphically represent each of the characters in the digital signal. The ...

A merchandising display gondola for floor mounting has been provided with an upright frame and at least one forwardly extending bottom support frame that has a lower, floor hugging, horizontal positioning. A pair of caster wheels are carried by a front end portion of the bottom frame, and a rounded, cross-extending, floor-engaging, tubular glide member is positioned adjacent a back end of the support frame. The glide member with the front casters positions the structure in a stable, supported po...

This invention relates to a device which can be used as a telautograph to send graphic messages via telephone lines and provide real time graphic communication between two or more stations. Handwriting and sketches or drawings can be sent and received by the same device. A hard copy of the communicated messages is reproduced at each station. The device or a modified version of the device can also be used to communicate with a computer to record and retrieve graphic information on a tape recorder...
