Abstract

Abstract A recording apparatus in which a recording head for effecting recording on a recording medium can be carried on a carriage movable with a reading unit for performing an original reading operation carried thereon, including a white flat plate member removable provided at a location opposed to the reading unit and along an area in which the carriage is moved. A reading unit for use in a recording apparatus in which a recording head unit for effecting recording on a recording medium and the reading unit for reading the image of an original are selectively interchangeable relative to a reciprocally movable carrier, including original image reading means constituting a predetermined reading optical path entering and reflected by the surface of the original to read the image of the original, and a movable member having reference correction means for reading moved to a position on the reading optical path corresponding to the surface of the original when the carrier is in a predetermined position.

A reading unit according to claim 5, wherein said reference correction means comprises a white reference or a pattern mark.
Claim 10
Dependent Claim 25 words
A reading unit according to claim 5, wherein said recording head is an ink jet recording head for discharging ink from an ink discharge port.
Claim 11
Dependent Claim 34 words
A reading unit according to claim 5, wherein said recording head is an ink jet recording head for discharging ink from an ink discharge port by heat energy applied by an electro-thermal conversion member.
Claim 12
Dependent Claim 88 words
A recording apparatus having mounting means operable to selectively mount a recording head for discharging ink to record an image and an image scanner unit for reading an image recorded on a recording medium and a white reference provided opposed to said mounting means and having a reference surface to calibrate said image scanner unit, said apparatus comprising: separating means for separating the reference surface of said white reference from a space where said recording head records in said apparatus when said image scanner unit is not calibrated.
Claim 13
Dependent Claim 88 words
A recording apparatus having mounting means operable to selectively mount a recording head for discharging ink to record an image and an image scanner unit for reading an image recorded on a recording medium and a white reference provided opposed to said mounting means and having a reference surface to calibrate said image scanner unit, said apparatus comprising: separating means for separating the reference surface of said white reference from a space where said recording head records in said apparatus when said image scanner unit is not calibrated.
Claim 14
Dependent Claim 39 words
