The present invention relates to a multipurpose handheld electronic computer.
New-generation portable electronic computers which include a large number of functions in a single apparatus whose size and weight are so small that it can be used on the palm of a hand are already known.
These portable computers generally comprise, in the same body, a keyboard, a display, a CPU, a work memory, a mass storage device, and optionally a clock/calendar, an acoustic warning device, and a communications interface.
In various configurations it is possible to provide a printer for printing on paper rolls.
The use of this type of printer leads to a series of operational limitations and drawbacks, the main one being due to the fact that, after printing, the paper from the roll remains curled or indeed rolls up due to a "memory" effect.
Furthermore, a blackening effect occurs, due to compression, for rolls of chemical or impact paper on their innermost layers when multiple copies are used; this effect consequently worsens printout legibility.
Printing from a roll furthermore does not allow to obtain fiscal or incremental numbering on multiple copies in a way that maintains alignment between the original and the copies from the beginning of the roll to its end.


A principal aim of the present invention is therefore to provide a multipurpose handheld electronic computer that eliminates the drawbacks and limitations described above in known types.
A consequent primary object is to provide users with a handheld electronic computer that is particularly handy and versatile.
Another object is to provide an ergonomic electronic computer that can be used just with the very hand on the palm whereof it rests for use.
Another object is to provide an electronic computer to which optional modules can be connected.
This aim, these objects, and others which will become apparent hereinafter are achieved by a multipurpose handheld electronic computer of the type which comprises, in a same box-like body, a keyboard, a display, a CPU, a work memory, a mass storage device, and optional other components such as an acoustic warning device, a clock-calendar, and a communications interface, characterized in that it has a printer for printing fanfold and/or single forms in one or more copies.


Further characteristics and advantages of the invention will become apparent from the following detailed description of an embodiment thereof, illustrated only by way of non-limitative example in the accompanying drawings, wherein:
FIG. 1 is a top view of the computer;
FIG. 2 is a bottom view of the computer;
FIG. 3 is a side view of the computer;
FIG. 4 is a schematic longitudinal sectional view of the computer.


With reference to the above figures, an electronic computer according to the invention comprises, in a same elongated flat box-like body 10, made of dust-proof and rain-proof impact-resistant plastic material and composed of two half-shells 11 and 12 joined by screws 13, an electronic motherboard 14 with a CPU, a work memory, and a mass storage device, to which a display 15 and a keyboard 16 are connected.
It is possible to provide for other components, not shown, such as an acoustic warning device, a clock-calendar, and a communications interface.
According to the invention, in this embodiment said box-like body 10 also accommodates a printer 17 for printing on fanfold forms 18.
A lower storage compartment 19 is provided for said forms and can be accessed from an upper loading door 19a.
Said compartment 19 is protected against rain.
As regards the arrangement, with reference to the ergonomics of the unit, the display 15 is arranged in the lower part, the keyboard 16 is located in the median region, and the slit 20 for the exit of the paper of the form 18 is located in the upper part of the body 10.
Of course, in other embodiments the layout of the keyboard and/or of the display may be altered and customized, and the
