Abstract
Abstract In a copying apparatus of the type having a movable original carriage, there is provided drive velocity changing means for changing the drive velocity of the original carriage relative to an image forming member. Movable optical means is provided which has at least a mirror and a lens. One or both of the mirror and the lens may be moved or changed over in response to the drive velocity changing means, thereby changing the magnification at which an original is copied.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
110 words
A copying apparatus for varying the magnification of images projected from an original onto a recording member comprising: a reciprocable original carriage; means for producing an image of the original; optical means for projecting the image from a scanning position, said optical means including a mirror and lens combination movable to vary the magnification of the projected image and wherein said scanning position varies with movement of said mirror and lens combination; means for moving the recording member past the projected image to thereby form an image on the recording member; and control means for actuating said moving means in accordance with the position of said mirror and lens combination.
Claim 2
Dependent Claim
110 words
A copying apparatus for varying the magnification of images projected from an original onto a recording member comprising: a reciprocable original carriage; means for producing an image of the original; optical means for projecting the image from a scanning position, said optical means including a mirror and lens combination movable to vary the magnification of the projected image and wherein said scanning position varies with movement of said mirror and lens combination; means for moving the recording member past the projected image to thereby form an image on the recording member; and control means for actuating said moving means in accordance with the position of said mirror and lens combination.
Claim 3
Dependent Claim
19 words
A copying apparatus according to claim 1, wherein said moving means includes feed rollers for a photosensitive recording sheet.
Claim 4
Dependent Claim
18 words
A copying apparatus according to claim 1, further comprising cam means for moving said mirror and lens combination.
Claim 5
Dependent Claim
23 words
A copying apparatus according to claim 1, wherein said control means is operatively connected with the mirror and lens arrangement for movement therewith.
Claim 6
Dependent Claim
33 words
A copying apparatus according to claim 1, further comprising a control member operatively associated with said optical means and including switching means mounted thereon to control the reciprocal movement of said original carriage.
Claim 7
Dependent Claim
19 words
A copying apparatus according to claim 5, wherein said control means includes a switch mounted on said control member.
Claim 8
Dependent Claim
165 words
A copying apparatus for varying the magnification of images projected from an original onto a recording member comprising: an original carriage; drive means to reciprocate said original carriage at varying velocities; means for producing an image of said original; optical means for projecting the image from a scanning position, said optical means including a mirror and lens combination movable to vary the magnification of the projected image and wherein said scanning position varies with movement of said mirror and lens combination; means for moving the recording member past the projected image to thereby form a image on the recording member; control means operatively connected to said mirror and lens combination to actuate said moving means in accordance with the position of said mirror and lens combination; and magnification changing means for simultaneously controlling the movement of the mirror and lens combination, the position of said control means and the drive velocity for said driving means in accordance with a desired magnification of the original image.
Claim 9
Dependent Claim
165 words
A copying apparatus for varying the magnification of images projected from an original onto a recording member comprising: an original carriage; drive means to reciprocate said original carriage at varying velocities; means for producing an image of said original; optical means for projecting the image from a scanning position, said optical means including a mirror and lens combination movable to vary the magnification of the projected image and wherein said scanning position varies with movement of said mirror and lens combination; means for moving the recording member past the projected image to thereby form a image on the recording member; control means operatively connected to said mirror and lens combination to actuate said moving means in accordance with the position of said mirror and lens combination; and magnification changing means for simultaneously controlling the movement of the mirror and lens combination, the position of said control means and the drive velocity for said driving means in accordance with a desired magnification of the original image.
