Abstract
An image recording apparatus capable of recording images on both faces of a recording sheet by a combination of image reading devices for reading both faces of the original in reciprocating scanning motion and recording devices for image recording on both faces of the sheet. The reading devices are capable of reading the original in either scanning direction, and the recording devices are capable of image recording corresponding to either image scanning direction.
Claims30
An image recording apparatus comprising:
- image reading means for reading images on first and second faces of an original by relative displacement thereto in a first direction or in a second direction;
- first recording means for image recording on a first face of a recording sheet;
- second recording means for image recording on a second face of said recording sheet after passing said first recording means;
- and
- control means for causing said first and second recording means to record the image signals respectively of said first and second faces of the original read during said relative displacement in said first direction, and for causing said first and second recording means to record the image signals respectively of said second and first faces of the original read during said relative displacement in said second direction.
2 more elements
An image reading device comprising:
- transport means for transporting a sheet original;
- image reading means for reading the image on said original during transportation by said transport means;
- detecting means for detecting the completion of original image reading by said image reading means;
- and
- control means for inverting the original transport direction of said transport means in response to a detection signal from said detecting means.
2 more elements
An image recording apparatus comprising:
- image reading means for reading an original image by relative displacement thereto in a first direction or in a second direction;
- recording means for image recording on a recording sheet in response to image signals obtained from said image reading means;
- inverting means for inverting the recording sheet recorded by said recording means;
- and
- control means for activating said inverting means in response to the direction of said relative displacement of said image reading means.
2 more elements
An image recording apparatus comprising:
- a transport path for transporting a recording sheet;
- first recording means for image recording in response to image signals on a first face of said recording sheet during transportation thereof along said transport path;
- and
- second recording means positioned in an opposed relationship to said first recording means across said transport path for image recording in response to image signals on a second face of said recording sheet during transportation thereof along said transport path.
1 more element
An image recording apparatus comprising:
- a transport path for transporting a recording sheet;
- first recording means for image recording on a first face of said recording sheet at a first position on said transport path;
- second recording means for image recording on a second face of said recording sheet at a second position downstream of said first position along said transport path;
- and
- mode selecting means for selecting either a two-side recording mode for image recording on said first and second faces of the recording sheet by said first and second recording means, or a one-side recording mode for image recording on one face only of said recording sheet.
2 more elements
An image recording apparatus comprising:
- first image reading means for reading an image on a first face of an original;
- second image reading means for reading an image on a second face of said original;
- a transport path for transporting a recording sheet;
- first recording means for image recording on a first face of said recording sheet at a first position on said transport path in response to the image signals from said first image reading means;
- and
- second recording means for image recording on a second face of said recording sheet at a second position downstream of said first position along said transport path in response to the image signals from said second image reading means;
- wherein the distance between said first and second image reading means is selected equal to the distance between said first and second positions.
4 more elements
An image recording apparatus comprising:
- selecting means for selecting either a first recording mode for image recording on both faces of a recording sheet or a second recording mode for image recording on one face of said recording sheet;
- first storage means for storing recording sheets for two-side recording;
- second storage means for storing recording sheets for one-side recording;
- and
- feed means for feeding said recording sheets either from said first storage means or from said second storage means in response to a recording mode selected by said mode selecting means.
2 more elements
An image recording apparatus comprising:
- image reading means for reading an image on an original by relative displacement thereto in a first direction or in a second direction;
- recording means for image recording on a recording sheet in response to image signals obtained from said image reading means;
- and
- plural recording sheet receiving members for separately receiving the recording sheets recorded by said recording means according to the direction of said relative displacement of said image reading means.
