Thank you very much for your kind helps !
Kudos to Higgles for the brilliant dianosis of the problem !
And ...finally, I found an excellent freeware that solves this bothersome issue once and for all :
3DPageFlip PDF to ePub Converter
I used it to convert the same pdf ebook then used Calibre to load it on to Mini Kobo reader . It came out exacltly as it should be : no more unwanted empty spaces & useless new paragraphs !!
Again, thank you everyone for the kind comments ..
Best regards,
