US4826147A — Paper feed cassette

Claim 1

Independent Claim 172 words

In a paper feeding cassette adapted for feeding sheets in or into a copying machine, the paper feeding cassette comprising a base member and four side members enclosing the base member and meeting the base member at right angles and a bottom plate positioned on top of the base and adapted to support the sheets to be fed and pivot about a fulcrum near at least one of the side members, the improvement in which: at least two of said side members having holes that extend into portions of said base member at substantially central portions thereof, and means external of said holes in said at least two side members and portions of said base member adapted when the cassette is inserted into the copying machine to lift said bottom plate such that the sheet can be fed from the cassette in either a first or second direction depending on which of the holes in said at least two side members is placed in communication with said means external of the cassette.

Claim 2

Dependent Claim 172 words

In a paper feeding cassette adapted for feeding sheets in or into a copying machine, the paper feeding cassette comprising a base member and four side members enclosing the base member and meeting the base member at right angles and a bottom plate positioned on top of the base and adapted to support the sheets to be fed and pivot about a fulcrum near at least one of the side members, the improvement in which: at least two of said side members having holes that extend into portions of said base member at substantially central portions thereof, and means external of said holes in said at least two side members and portions of said base member adapted when the cassette is inserted into the copying machine to lift said bottom plate such that the sheet can be fed from the cassette in either a first or second direction depending on which of the holes in said at least two side members is placed in communication with said means external of the cassette.

Claim 3

Dependent Claim 107 words

A paper feed cassette, comprising: a rectangular base member; four side members enclosing said base member and meeting said base member at right angles, two of said side members having holes that extend into portions of said base member at substantially central portions thereof in order to facilitate positioning of the cassette for paper feeding from the cassette in either of two directions with one of said two directions being at a right angle with respect to the other, and a bottom plate having a fulcrum near at least one side of the two of said side members other than said two side members having holes therein.

Claim 4

Dependent Claim 107 words

A paper feed cassette, comprising: a rectangular base member; four side members enclosing said base member and meeting said base member at right angles, two of said side members having holes that extend into portions of said base member at substantially central portions thereof in order to facilitate positioning of the cassette for paper feeding from the cassette in either of two directions with one of said two directions being at a right angle with respect to the other, and a bottom plate having a fulcrum near at least one side of the two of said side members other than said two side members having holes therein.

Claim 5

Dependent Claim 133 words

A cassette for holding stacked substrates for extraction in either of two orthogonal directions, including a base member, at least two orthogonal sides contiguous to the base and to each other, two apertures through the base and the adjacent sides, and a bottom late adapted to support stacked substrates thereon and to be tilted by means external to said cassette extending through the apertures in order to position the substrates for extraction, and wherein the direction along which the substrates can be extracted is dependent upon the orientation of the cassette, said base member being enclosed by four orthogonal sides, and wherein said apertures are positioned centrally of the respective sides, and wherein said bottom plate has at one fulcrum near at least on of the sides other than the sides with apertures.

Claim 6

Dependent Claim 133 words

A cassette for holding stacked substrates for extraction in either of two orthogonal directions, including a base member, at least two orthogonal sides contiguous to the base and to each other, two apertures through the base and the adjacent sides, and a bottom late adapted to support stacked substrates thereon and to be tilted by means external to said cassette extending through the apertures in order to position the substrates for extraction, and wherein the direction along which the substrates can be extracted is dependent upon the orientation of the cassette, said base member being enclosed by four orthogonal sides, and wherein said apertures are positioned centrally of the respective sides, and wherein said bottom plate has at one fulcrum near at least on of the sides other than the sides with apertures.

Claim 7

Dependent Claim 46 words

The cassette of claim 3, in which the bottom plate has two legs projecting from each of two orthogonal edge surfaces thereof, there being two pairs of complementary passages in the cassette base in which the legs engage to provide alternative pivots for the bottom plate.
