【NEC】 Bungo mini 5RC

NEC began selling the mini5RC personal laptop word processor in February 1991. It was the world’s first word processor with a paper auto-loading mechanism that automatically fed paper from the paper tray located under the keyboard to the printer.

The mini5RC had the following features.
  • (1)The mini5RC was standard equipped with a paper auto-loading mechanism that automatically fed paper from the paper tray located under the keyboard to the printer. This made printing easier and less time intensive and also improved the unit’s storage capability.
  • (2)The mini5RC made printing more efficient with the standard form print function, which enabled the user to create and print standard forms, such as cover sheets and letterheads, ahead of time and then later print as needed just the portion of the forms that changed.
  • (3)High-quality text printing was achieved with the outline font generation function, which could print smooth, attractive scaled characters from both the standard character set and the extended character set. This function also supported the optional Kyokasho and Maru Gothic typefaces.
  • (4)The mini5RC’s fast printing was achieved through the combination of a high-speed 16-bit V33 CPU, a 128-dot multi-line printer that could print as many as 2.6 lines per pass, a double buffer that could efficiently position the print head by looking ahead at the subsequent print data, and a super-quick return design that made efficient use of the printer’s three motors.
  • (5)The word processor came with Mincho, Gothic, and Mouhitsu typefaces standard, making it easy to create sharp-looking text.
  • (6)Operating costs were lowered by supporting inked ribbon cartridges that could be used multiple times.
