Abstract

A printer, comprises for forming an image on a surface of a recording media: preprocessing means for preprocessing the surface of the recording media to form an image on the surface of the recording media; post-processing means for post-processing the surface of the recording media preprocessed by the preprocessing means to form the image on the surface of the recording media; a recording media feed path formed between the preprocessing means and the post-processing means; first feed means arranged on an upstream side of the recording media feed path; and, second feed means arranged on a downstream side of the recording media feed path; wherein the first feed means and the second feed means are made different in driving control from each other. For printing a plurality of recording media successively, no large-scale arrangements are provided for printing processes to meet a required printing accuracy and to shorten a processing time.

Claims

1. A printer, comprising in combination:

preprocessing means for preprocessing a surface of a recording media to form an image on said surface of said recording media;

post-processing means for post-processing said surface of said recording media preprocessed by said preprocessing means to form said image on said surface of said recording media;

a recording media feed path formed between said preprocessing means and said post-processing means;

first feed means arranged on an upstream side of said recording media feed path; and

,

second feed means arranged on a downstream side of said recording media feed path;

wherein said first feed means and said second feed means are made different in driving control from each other.

2. The printer according to claim 1, wherein driving supply to said second feed means is run while driving supply to said first feed means is stopped, thereby feeding said preceding recording media to said post-processing means.

3. The printer according to claim 1, further comprising in combination:

a switchback section for substantially extending said recording media feed path wherein said second feed means is provided in said switchback section.

4. The printer according to claim 3, wherein said switchback section has a switchback path installed therein vertically and said second feed means is arranged on said switchback path and has a switchback driving arrangement for independently driving said second feed means.

5. The printer according to claim 1, wherein a switching gate is provided between said first feed means and said second feed means on said recording means feed path for switching a feed direction for said recording media, said switching gate being movable between a first position for guiding said recording media fed by said second feed means to said post-processing means and a second position for opening said upstream side and said downstream side on said recording media feed path for allowing said recording media to be transferred from said first feed means to said second feeding means.

6. The printer according to claim 5, wherein said second feed means comprised a reverisble feed roller and said switching gate is positioned at said first position in synchronous with either of normal or reverse rotation of said feed roller.

7. The printer according to claim 1, wherein said preprocessing means has an exposing section for making exposure on said recording media and said post-processing means has a developing section for making development by pressing said recording media having the exposure made thereon by said exposing section.

8. The printer according to claim 7, wherein said developing section has a pressure roller for pressing said recording media at a specific pressure and for feeding said recording media and a feed speed of said recording media fed by said pressure roller is slower than a feed speed of said recording media fed by said first and second feed means.

9. The printer according to claim 8, further comprising in combination:

a cutting section for cutting edges of said recording media developed by said developing section and third feed means for feeding to said cutting section said recording media developed by said developing section, wherein a feed speed of said recording media fed by said third feed means is faster than a feed speed of said recording media fed by said pressure roller.

10. The printer according to claim 9, wherein said feed speed of said recording media fed by said first and second feed means is virtually same as said feed speed of said recording media by said third feed means.
