Recorder with display indicating a symbol for text and graphical data

A method of selectively displaying, on an indicator area of display means of a recording apparatus, one of a plurality of numerical values of one of plural groups of numerical data which are represented in a graphical or tabular form and which are stored in memory means, comprising the steps of:

• designating one of a plurality of blocks of a hypothetical table which is defined by a plurality of rows and a plurality of columns such that said blocks of said hypothetical table accommodate said numerical values of said plural groups of numerical data, respectively;
• retrieving one of said numerical values from said memory means when the corresponding block of said hypothetical table is designated;
• displaying said one numerical value on said indicator area;
• designating another of said blocks of said hypothetical table which is located adjacent to said one block;
• retrieving from said memory means another of said numerical values which corresponds to said another block of said hypothetical table;
• and
• displaying said another numerical value on said indicator area as if said indicator area and said hypothetical table are moved relative to each other such that said indicator area is moved from said one block to said another block of said hypothetical table.

A recording apparatus capable of recording characters and graphical representations on a recording medium with a recording instrument, said graphical representations including a graph which represents plural groups of numerical data, each of said plural groups of numerical data consisting of a plurality of numerical values, said recording apparatus comprising:

• an input device through which character data and graph data are entered, said graph data including said plural groups of numerical data;
• display means for displaying said character data and said group data entered through said input device, said display means including at least one indicator area adapted to display said numerical values one at a time;
• memory means comprising a text memory for storing said character data, and a graph memory for storing said graph data;
• a recording mechanism for effecting relative movements between said recording instrument and said recording medium, for recording said characters and said graphical representations on said recording medium with said recording instrument;
• control means for controlling said display means and said recording mechanism according to said character data and said graph data;
• said control means being operable to store in said text memory a set of special symbol data indicative of a storage of said graph data in said graph memory, said special symbol data corresponding to each one of said graphical representations, said control means being further operable to control said display means so as to display a special symbol represented by said special symbol data, together with said characters represented by said character data;
• designating means for designating one of a plurality of blocks of a hypothetical table which is defined by a plurality of rows and a plurality of columns, said blocks of said hypothetical table accommodating said numerical values of said plural groups of numerical data, respectively, said display means displaying said numerical values on said indicator area when the corresponding blocks are designated by said designating means;
• and
• indication control means operable while one of said numerical values which corresponds to said one block designated by said designating means is displayed on said indicator area of said display means, for retrieving from said graph memory another of said numerical values of said plural groups of numerical data which corresponds to another block of said hypothetical table, when said another block is designated by said designating means, said another block being located adjacent to said one block, and for operating said display means to display on said indicator area said another numerical value retrieved from said graph memory, whereby said another numerical value is displayed as if said indicator area is moved from said one block to said another block of said hypothetical table.

A recording apparatus capable of recording graphical representations and/or data tables on a recording medium with a recording instrument, comprising:

• an input device through which plural groups of numerical data are entered for one of said graphical representations and/or data tables, each one of said plural groups of numerical data consisting of a plurality of numerical values;
• memory means for storing said plural groups of numerical data entered through said input device;
• a recording mechanism for effecting relative movements between said recording instrument and said recording medium, for recording said graphical representations and/or data tables on said recording medium with said recording instrument;
• recording control means for controlling said recording mechanism according to said plural group of numerical data stored said memory means;
• display means including at least one indicator area adapted to display said numerical values of said plural groups of numerical data, one value at a time;
• designating means for designating one of a plurality of blocks of a hypothetical table which is defined by a plurality of rows and a plurality of columns, said blocks of said hypothetical table accommodating said numerical values of said plural groups of numerical data, respectively, said display means displaying said numerical values on said indicator area when the corresponding blocks are designated by said designating means;
• and
• indication control means operable while one of said numerical values which corresponds to said one block designated by said designating means is displayed on said indicator area of said display means, for retrieving from said memory means another of said numerical values of said plural groups of numerical data which corresponds to another block of said hypothetical table, when said another block is designated by said designating means, said another block being located adjacent to said one block, and for operating said display means to display on said indicator area said another numerical value retrieved from said memory means, whereby said another numerical value is displayed as if said indicator area and said hypothetical table are moved relative to each other such that said indicator area is moved from said one blcok to said another block of said hypothetical table.
