Abstract
It is determined whether recording paper set in a copying apparatus is oriented sideways or in the lengthwise direction, and it is determined whether an original has been set on a platen sideways or in the lengthwise direction. Based upon these determinations and a designated binding direction in which the recording paper is to be bound, the image read from the original is rotated through a predetermined angle in a two-dimensional plane and the rotated image is then printed out on the recording paper. This makes it possible to perform double-sided copying in a normal manner irrespective of the orientation of the original on the platen.
Claims50
An image copying apparatus comprising:
- discriminating means for discriminating a direction at which one or more original(s) have been placed on a scanner, the scanner providing first and second original images with a relative orientation therebetween from the original(s);
- deciding means for deciding a first angle of rotation of the first original image, and for deciding a second angle of rotation of the second original image;
- and
- image forming means for forming the first original image onto a first face of a recording paper at the first angle of rotation, and for forming the second original image onto a second face of the recording paper at the second angle of rotation,
- wherein said deciding means decides the first and second angles of rotation based upon the discriminated direction of the original(s) and based upon whether the first original image or the second original image is to be formed, so that a relative orientation between the first and second original images formed onto the first and second faces of the recording paper, respectively, is the same as the relative orientation between the first and second original images irrespective of the direction of the original(s) and regardless of how the recording paper is handled by said image forming means.

An image copying apparatus comprising:
- a scanner which includes a scanning surface and which generates first and second original images from one or more original(s) placed on the scanning surface, said scanner defining a prescribed position on the scanning surface against which the original(s) may be placed width-wisely or length-wisely;
- first detecting means for detecting whether the original(s) have been placed width-wisely or length-wisely at the prescribed position and for generating a placement direction signal in accordance with the detection;
- feed means for feeding a recording paper to an image forming station, said feed means including second detecting means for detecting whether the recording paper is fed width-wisely or length-wisely and for generating a paper direction signal in accordance with the detection;
- image forming means arranged at the image forming station for forming the first original image in accordance with a first scanning of the original(s) by said scanner on a first face of the recording paper, and for forming a second original image in accordance with a second scanning of the original(s) by said scanner on a second face of the recording paper;
- and
- deciding means for deciding first and second angles of rotation for rotating the first and second original images, respectively, said deciding means rotating the first and second original images based on the placement direction signal and the paper direction signal and based on whether the first original image or the second original image is to be formed, such that the first original image and the second original image are recorded on respective first and second faces of the recording paper such that a relative orientation between the first and second original images recorded on the first and second faces of the recording paper, respectively, is the same as the relative orientation between the first and second original images, irrespective of whether the original(s) have been placed width-wisely or length-wisely at the prescribed position, irrespective of whether the recording paper has been fed width-wisely or length-wisely, and regardless of how the recording paper is handled by said image forming means.

An image copying method, comprising the steps of:
- (a) discriminating a direction at which one or more original(s) have been placed on a scanner, the scanner providing first and second original images with a relative orientation therebetween from the original(s);
- (b) deciding a first angle of rotation of the first original image, and a second angle of rotation of the second original image;
- and
- (c) forming the first original image onto a first face of a recording paper at the first angle of rotation, and forming the second original image onto a second face of the recording paper at the second angle of rotation,
- wherein in said step of deciding, the first and second angles of rotation are decided based upon the direction of the original(s) and based upon whether the first original image or the second original image is to be formed, so that a relative orientation between the first and second original images formed onto the first and second faces of the recording paper, respectively, is the same as the relative orientation between the first and second original images, irrespective of the direction of the original(s) and regardless of how the recording paper is handled in said forming step.
