This invention is a family of simple, inexpensive, and portable electronic devices for business support built around a simple 2-dimensional digitizing device. It includes a transmit-only facsimile transmission device/system, a simple computer-based facsimile system, and a dual-mode (digital or OCR) page reading device. The digitizing device includes a read bar having a linear read head for developing a signal reflecting a one dimensional line of viewing; apparatus for creating relative movement between sheets of material to be digitized and the read bar; and, a detector for developing a signal indicating movement of the sheets one scanned line distance. The simple transmit-only facsimile transmission system comprises the foregoing digitizing device and, a digital computer including a numeric input keyboard; a modem for connecting to a telephone line; buffer memory for receiving the entire digitized contents of a 2-dimensional viewing area; and, a first program for inputting telephone numbers, for establishing a connection to a receiving facsimile machine, for determining group type of the receiving machine, and for transmitting the digitized contents of buffer memory to the receiving machine in the proper format for its group type. When employed in the portable office, the system can be used as a photocopier to copy documents. The digitizing device can output digitized or OCR data.

A simple 2-dimensional digitizing device comprising: (a) a planar case including a scanning area for containing materials to be digitized; (b) a read bar mounted for movement across said scanning area and parallel thereto, said read bar including a linear read head for developing a first electrical signal at an output thereof reflecting a one dimensional line of viewing of said read head as said head is moved over said scanning area, said read bar further including means for manually moving said read bar over said scanning area; (c) means for developing a second electrical signal indicating movement of said read bar across said scanning area a pre-defined distance defining the distance between one scanned line of said scanning area and the next said scanned line; (d) governor means operably connected to said read bar for limiting the speed of movement of said read bar over said scanning area; (e) a buffer memory for receiving the entire digitized contents of said viewing area as said viewing area is scanned by said read bar; and, (f) logic means for establishing a connection to a receiving facsimile machine over a telephone line, for determining the group type of said receiving machine, and for transmitting the digitized contents of said buffer memory to said receiving machine in the proper format for its said group type.
