A facsimile apparatus includes a transmission motor (90) and when an, original to be transmitted is moved by the transmission motor in a sub-scanning direction, sequential lines in the sub-scanning direction are scanned by a contact image sensor (100) in a main scanning direction and therefore, image data of a black, dot or a white dot is outputted by the contact image sensor.

Why it's free to use
- Filed May 9, 1996 and granted July 31, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 9, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 9, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
