Abstract

Abstract A recording apparatus having a printer mechanism 5 for printing images successively on sheets of copying paper, and an image control circuit 2 for delivering image information controllably to the printer mechanism 5 to enable the latter to print the images successively. The image control circuit 2 includes a plurality of page memories 3 and 4 each for storing image information per single page, a first changeover switch 9 for writing image information selectively into the page memories 3 and 4, and a second changeover switch 11 for reading image information selectively from the page memories 3 and 4. When a sheet of copying paper is jammed in the printer mechanism 5, a microcomputer system 18 controls the second changeover switch 11 to select a switching mode to read an item of image information out of one of the page memories 3 and 4 which stores the item of information to be printed on the jammed sheet of copying paper, for thereby allowing the image to be printed in a shorter period of time after paper jam clearance.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 157 words
A recording apparatus having a printer mechanism for printing images successively on sheets of copying paper, characterized by an image control circuit 2 for delivering image information controllably to the printer mechanism 5 to enable the latter to print the images successively, said image control circuit 2 including a plurality of page memories 3 and 4 each for storing image information per single page, a first changeover switch 9 for writing information selectively into the page memories 3 and 4, and a second changeover switch 11 for reading image information selectively from the page memories 3 and 4; and control means 10 and 18, upon paper jam occurrence in the printer mechanism 5, for placing the second changeover switch 11 in a switching mode to read an item of image information out of one of the page memories 3 and 4 which stores said item of information to be printed on the jammed sheet of copyinq paper.
Claim 2
Dependent Claim 157 words
A recording apparatus having a printer mechanism for printing images successively on sheets of copying paper, characterized by an image control circuit 2 for delivering image information controllably to the printer mechanism 5 to enable the latter to print the images successively, said image control circuit 2 including a plurality of page memories 3 and 4 each for storing image information per single page, a first changeover switch 9 for writing information selectively into the page memories 3 and 4, and a second changeover switch 11 for reading image information selectively from the page memories 3 and 4; and control means 10 and 18, upon paper jam occurrence in the printer mechanism 5, for placing the second changeover switch 11 in a switching mode to read an item of image information out of one of the page memories 3 and 4 which stores said item of information to be printed on the jammed sheet of copyinq paper.
Claim 3
Dependent Claim 78 words
A recording apparatus according to claim - 1, characterized in that the printer mechanism 5 includes a paper feed path 28 and a plurality of detectors 35, 36 and 37 disposed along the paper feed path 28 for detecting paper jams therein, and said control means 10 and 18 comprises a a microcomputer system 18 in response to signals from the detectors 35, 36 and 37 for controllinq the second changeover switch 11 to select the switching mode.
Claim 4
Dependent Claim 61 words
A recording apparatus according to claim 1, characterized in that the printer mechanism 5 comprises a test pattern generator 17 and a third changeover switch 16 actuatable for disconnecting the image control mechanism and enabling said printer mechanism 5 to print a test pattern on a sheet of copying paper in response to a signal from the test pattern generator 17.
