Claim 1
Independent Claim
126 words
A feed mechanism for feeding stationery having feed perforations, the feed mechanism including a support member movably mounted on a frame and a pin for engaging a feed perforation, the pin being resiliently mounted on the support member so that during relative movement of the pin and the stationery, the pin is moved by the stationery against the action of the resilient bias until the feed perforation is in register with the pin when the pin, due to the action of the resilient bias, engages the feed perforation wherein a portion of the pin is made of resilient material and can pass through an aperture in the support member by temporary distortion of the portion so that the pin can be movably retained in the aperture.
Claim 2
Dependent Claim
