Definitions

  • This invention concerns a miniaturized typewriter.
  • Machines of the same size as electronic pocket calculators are also known. In addition to performing the mathematic functions planned, these are programmed to memorize.certain data corresponding to a few addresses, names or the like so that they may be viewed as desired on the display. However, these may not be considered typewriters since they have no traditional keyboard which would allow them to be used by anyone with a knowledge of typing. In fact, these machines have the same rectangular structure as most calculators, with the longer side vertical and with the alphabetic characters arranged in simple succession. This arrangement leads to great difficulty and lengthy composition times even for the few simple words which may be typed. On its part, the display is placed on the smaller edge of the rectangle and shows only a few words at a time.
  • the aim of this invention is to develop a real pocket typewriter which can either be held in one hand and used with the other like a traditional machine or be placed on a flat surface and used with both hands. It will allow each text typed to be viewed on a line of display with subsequent memorization line by line.of information corresponding to several pages. This information may be stored even over long periods and redisplayed when needed, or may be transferred to a paper printing device incorporated in the machine or connected to the electronic memory as required.
  • this aim is achieved with a rectangular structure with the longer edge horizontal equipped with miniaturized keys arranged as the traditional keyboard in addition to multiple function control keys.
  • This arrangement is beneath one or two lines of display (perhaps of the liquid crystal type) with a planned length of approximately 32 characters.
  • Said structure contains a microcomputer programmed to effect the typing performed with said keys; this typing is displayed in succession for visual verification and then is accumulated line by line in the memory. This text is stored there even when the machine is not in use to be redisplayed on the same display using the read key.
  • a portable electronic typewriter composed basically of an alphanumeric display, an alphanumeric keyboard and a RAM access memory capable of storing a text typed on the keyboard and viewed on the display.
  • This memory can store its contents for any number of days, even when the machine is not in use.
  • Certain keys also have control functions related to the EDIT of the typed text or to the check of peripheral functions, described below.
  • Batteries serve to operate the machine and store memory. The dimensions of the machine and the batteries allow the finding to be used as a portable typewriter.
  • the batteries may be recharged by a line adaptor. This is also equipped with a port for exposing EPROM-type memory cartridges to UV light. When inserted in the typewriter, these cartridges allow the memory of the device to be expanded so that when one or more is used the EDITed typed text may be stored for an indefinite period.
  • E 2 ROM-type memory cartridges may also be used which can be erased electrically on the machine itself.
  • the E 2 ROM or EPROM memory cartridge is connected by a cable and placed in a carrying case or suitable container; this allows larger amounts of memory.
  • the 'repeat mode' is reset and another command in the repeat mode is possible only by repeating the 'repeat' prefix.
  • PRINT - Prints the content of the memory starting from the line displayed. During printing, only the STOP command may be given.
  • STOP - During the typing phase, it displays a particular character which will be interpreted either in the print phase (PRINT), the temporary viewing phase (TIME), the storage phase (SAVE) as a stop command.
  • PRINT print phase
  • TIME temporary viewing phase
  • SAVE storage phase
  • MCLER Master Clear is a particular command to remove the calculator from an error situation which may be used following an internal error caused, for example, by discharged batteries, improper insertion of the power supply, improper insertion of the printer.
  • ADVP - Advance paper advances the paper in the printer.
  • TIME - Effects a timed display of the text starting from the line on the display until the end of the typed text or until aparticular character described above appears.
  • SAVE - (followed by a six letter name) - Stores the typing contained in the RAM in the cartridges by memorizing in a suitable table the name of the file and its initial and final address. This phase may be stopped by the following events:
  • LOAD (followed by a six letter name) - Reads the typewritten text from a file contained in the cartridge and memorizes it in the RAM.
  • the device functions as described below.
  • Operation is illustrated by the general execution flow in figure 6 and by the operation of the system hardware dedicated to peripherals control, tracint the flow of command execution and standard hardware (CPU, RAM, PROM, I/O seen from the bus side, qualification logic of the resources in the bus).
  • system hardware dedicated to peripherals control
  • tracint the flow of command execution and standard hardware (CPU, RAM, PROM, I/O seen from the bus side, qualification logic of the resources in the bus).
  • the general flow which effects initialization and the principal loop of memorization of characters as well as commands' execution, also shows the repeat mode which interacts deeply with the above LOOP and the print loop.
  • the principal LOOP uses a process P 2 for reading the characters from the keyboard (figure 7) which controls the cursor of the display and the state of the text memory as well as the keyboard itself.
  • Process P 2 is activated on a time slicing basis.
  • the individual pieces of data are acquired as follows:
  • the presence and configuration of the E 2 ROM/EPROM cartridge is determined when the IDENT signal is sent to the cartridge interface, and this responds with an 8- bit code (figure 5) from the configuration port 40.
  • the matrix keyboard is scanned through multiplexor 8. Any keys pressed are detected by the P.E. (10).
  • the scanned function is effected by process P 2 , which takes care of anti-rebound and supplies the code of the key read to process P 1 .
  • the software places the 6bit ASCI data for the character to be displayed on I/O port 7.
  • the seventh bit is the complement of the sixth, and the two bit address inside the display block for later typing is written on one of the 8 blocks through multiplexor 14.
  • the cursor is controlled by process P 2 through the typing of a special character.
  • the cartridge interface generates 16 address bits in output through the 16bit counter (17). This counter may be incremented by the INC signal (increment) 17A or zeroed by the RESET signal 17B.
  • said interface generates a data signal 15, controlled by port PI02, which is bidirectional and so allows both writing and reading operations to be effected. Finally, it also generates the following auxiliary signals:
  • the POMCL signal has the function not only of starting the system but also of disabling the typing in the memory through logic 6 when the system is functioning improperly (VCC 4.75 volts).
  • This signal is WIRED-ON with the MCL key.
  • the machine may be made with a traditional keyboard coupled with an incorporated printing device of a known type.
  • it may have a terminal connected to the micro-computer in a paper printer, to which the memorized information may be sent through a cable. In this way, either at the same time as the typing appears on the display or independently of it, actual mechanical typing may be performed.
