Abstract
Abstract A combined reader-printer apparatus operable in reader and printer modes one at a time for projecting an optical image of an original onto a viewing screen and reproducing the image on a photosensitive medium comprises first and second reflectors carried by a carriage in spaced relation to each other and a pivotable reflector pivotable between lowered and raised positions. These reflectors are so arranged that, when the apparatus is in the reader mode, the pivotable reflector is in the lowered position to reflect the image, which has been reflected by the first reflector, towards the screen, but when the apparatus is in the printer mode, the pivotable reflector is in the raised position to allow the image reflected by the first reflector to be guided towards the photosensitive medium by way of the second reflector. The carriage has a damper for absorbing any possible shock which would be generated upon contact with each of stoppers defining respective operative positions for the carriage.

Claim 1
Independent Claim
314 words
A combined reader-printer apparatus operable in two different, reader and printer modes one at a time for projecting an optical image of an original onto a viewing screen and reproducing the optical image of the original on a photosensitive medium, which comprises, in combination: an image forming means for forming the optical image of the original irrespective of the mode in which the apparatus is set to operate; first and second reflectors; a carriage carrying the first and second reflectors in spaced relation to each other, said first and second reflectors being so arranged and so supported thereby that, when the apparatus is set to operate in the printer mode, the optical image can be guided from the image forming means onto the photosensitive medium after having been reflected by the first reflector and then by the second reflector; a guide means for supporting the carriage for scanning movement between start and scanned positions in a direction parallel to an imaginary line drawn between the first and second reflectors; means for holding the carriage at a normal position when and so long as the apparatus is set to operate in the reader mode; a pivotable reflector supported for pivotal movement between first and second positions, said pivotable reflector when in the first position intercepting an optical path between the first and second reflectors for guiding the optical image, which has been reflected by the first reflector, towards the viewing screen, said pivotable reflector when in the second position being clear from the optical path between the first and second reflectors and also from the path of movement of the carriage, said pivotable reflector being set in the first and second positions respectively when the apparatus is in the reader and printer modes; and means operable when the apparatus is in the printer mode for driving the carriage reciprocately between the start and scanned positions.

A combined reader-printer apparatus operable in two different, reader and printer modes one at a time for projecting an optical image of an original onto a viewing screen and reproducing the optical image of the original on a photosensitive medium, which comprises, in combination: an image forming means for forming the optical image of the original irrespective of the mode in which the apparatus is set to operate; first and second reflectors; a carriage carrying the first and second reflectors in spaced relation to each other, said first and second reflectors being so arranged and so supported thereby that, when the apparatus is set to operate in the printer mode, the optical image can be guided from the image forming means onto the photosensitive medium after having been reflected by the first reflector and then by the second reflector; a guide means for supporting the carriage for scanning movement between start and scanned positions in a direction parallel to an imaginary line drawn between the first and second reflectors; means for holding the carriage at a normal position when and so long as the apparatus is set to operate in the reader mode; a pivotable reflector supported for pivotal movement between first and second positions, said pivotable reflector when in the first position intercepting an optical path between the first and second reflectors for guiding the optical image, which has been reflected by the first reflector, towards the viewing screen, said pivotable reflector when in the second position being clear from the optical path between the first and second reflectors and also from the path of movement of the carriage, said pivotable reflector being set in the first and second positions respectively when the apparatus is in the reader and printer modes; and means operable when the apparatus is in the printer mode for driving the carriage reciprocately between the start and scanned positions.
Claim 3
Dependent Claim
20 words
An apparatus as claimed in claim 1, wherein said normal position is located intermediately between the start and scanned positions.
Claim 4
Dependent Claim
35 words
An apparatus as claimed in claim 1, wherein said first and second reflectors are supported so as to incline at a rectangular angle relative to the imaginary line with their reflective surfaces facing each other.
Claim 5
Dependent Claim
80 words
An apparatus as claimed in claim 2, wherein said holding means comprises a damper means carried by the carriage for movement together therewith, and a movably supported stopper operable to project into the path of movement of the damper means, when the apparatus is set to operate in the reader mode, to hold the carriage at the normal position, said damper means being operable to absorb any possible shock which would be generated upon contact with the movably supported stopper.
Claim 6
Dependent Claim
50 words
An apparatus as claimed in claim 4, wherein the start position is defined by a fixed stopper said fixed stopper cooperating with said damper means when the carriage is moved from the normal position to the start position preparatory to the movement from the start position towards the scanned position.
