The Canon LX-40 looks different compared to its sibblings like the LC-8M and the LC-31. We don't know the meaning of the LX-abbreviation, most likely is eXperimental. 

LX-40_PCB.jpg (102022 Byte)Compared with all other known Canon calculators this one seems to be heavily inspired by some elder Sharp products. Instead of using a traditional printed circuit board (PCB) the LX-40 uses a flexible foil pressed against a heavy metal sheet. Not only the LC-display but even the calculator circuit missed any solder joint.

A similar interal construction was used with the later LC-44, F-44 and F-58 scientifical calculator.

The LX-40 seems to be a stylish variation of the LX-30, if you are missing the [+/-] key you should opt for the LC-33.
