Abstract: A form for printing print data, such as business data generated by an application program is generated by a form defining program. The form defining program designates a specific item (specific data item) in the form based on the predesignated print color of the form. A data discriminating section extracts data in a specific data item from the print data supplied from the application program. In accordance with the contents of the data in the specific data item, a color control command for changing the predesignated color of the form is generated. A printer controller change the color of the form in accordance with the color control command, supplied via a printer driver, and outputs the resultant data to a printing section. The printing section prints the print data in the color-changed form.

Abstract: Defining information for defining the condition for adding background colors is previously stored in a condition storage area, and a spreadsheet form is registered in a form storage area. Alphanumeric character data to be written in a cell of a spreadsheet are stored in a record storage area. When a CPU is instructed to start printing, the CPU outputs the alphanumeric character data as output data to a data value decision section. The data value decision section reads the output data and determines a background color in accordance with the read output data to prepare a print record to which color information is added. A printer control section prepares print data to which the background color is added in accordance with the color information for the print record and the spreadsheet form registered in the form storage area.

Abstract: A portable overhead projector includes a projection unit having a light source and a projection lens, a stage having a Fresnel lens which has a reflecting surface facing the projection unit, and an arm part for connecting the projection unit with the stage. The arm is sized to accommodate the projection unit and the stage when these are folded thereinto. The size of the projector when the projection unit and the stage are folded into the arm part is not substantially larger than approximately a length of 184 mm, a width of 135 mm, and a thickness of 58 mm. Since each member can be folded, it is possible to make the portable overhead projector compact so that users can conveniently carry such an overhead projector in their bags.

Abstract: In an image information recognition apparatus image information read by an image reader is stored in an image memory. Since the read image information corresponds to the entire reading range of the reader, an edge of a specific region of the image signals is detected by an edge detector. Boundaries of the region are determined by a coordinate emulator in accordance with a detection signal from the edge detector. Image information within the region surrounded by the boundaries is read out from the image memory, and a bit mover rotates the image information to a normal position or trims it, as needed.

Abstract: A document creating and editing apparatus operates in such a manner that information before editing or proofreading registered in a document memory is left at the time of the editing or proofreading, while only the area of an edited or proofread portion is registered in the document memory, that an editing or proofreading pointer is generated simultaneously with the registration of the area of the edited or proofread portion, and that the respective lines of a document before or after the editing or proofreading are chained in single memory block unit.
