Abstract
An apparatus for adjusting the position of a cylindrical image carrier relative to a scanning head is designed to cheaply and easily permit substantially reliable positioning. In the apparatus for adjusting the position of a cylindrical image carrier relative to a scanning head, in which apparatus the image carrier is mounted so as to be rotatable around its longitudinal axis, the image carrier can be swiveled around an axis perpendicular to the longitudinal axis. The invention can be applied to devices that generate images and to devices that reproduce images, in particular for the production of type forms and for the scanning of originals.
Claims14
A device for adjusting the position of a cylindrical image carrier, said device comprising:
- a cylindrical image carrier;
- said cylindrical image carrier being configured to carry an image;
- said cylindrical image carrier having a longitudinal axis of rotation;
- an apparatus to mount said image carrier so as to be rotatable around said longitudinal axis of rotation;
- and
- a scanning head arrangement configured and disposed to scan said image on said image carrier;
- and
- an apparatus disposed and configured to carry said scanning head arrangement adjacent said cylindrical image carrier;
- and
- said mounting apparatus comprising an arrangement to permit at least one end of said image carrier to swivel, said swivel arrangement being configured to swivel at least one end of said image carrier perpendicular to said longitudinal axis of rotation of said image carrier.
The device according to claimed 4 wherein said control arrangement comprises an arrangement being selectively configured to set the registration of said image carrier and at least one portion of said image carrier.
A method for adjusting the position of a cylindrical image carrier, said method comprising the steps of:
- (a) providing a cylindrical image carrier;
- said cylindrical image carrier being configured to carry an image;
- said cylindrical image carrier having a longitudinal axis of rotation;
- (b) providing an apparatus to mount said image carrier so as to be rotatable around said longitudinal axis of rotation;
- and
- (c) providing a scanning head arrangement configured and disposed to at least scan said image on said image carrier;
- (d) providing an actuator arrangement connectable to said cylindrical image carrier;
- (e) providing an apparatus disposed and configured to carry said scanning head arrangement adjacent said cylindrical image carrier;
- and said method further comprising the step of:
- (f) displacing said image carrier in said mounting apparatus relative to said scanning head arrangement by swiveling said image carrier perpendicular to said longitudinal axis of rotation of said image carrier to move said image carrier from an initial position to a desired position;
- and
- (g) aligning a registration of said image on said image carrier to a desired registration.
