Abstract
Abstract An interruption control system for an image forming apparatus with a scanning means for optically scanning a document comprises an image forming means, including a feed section for feeding an image forming medium, an image forming section for forming an image on the image forming medium using image information derived from the scanning means, a temporary storing section for temporarily storing the image forming medium when the image forming section forms an image, and a discharge section for discharging the image forming medium bearing an image formed by the image forming section. It also has an interruption commanding means for commanding the image forming means to interrupt the image forming operation, and an interruption control means, responsive to an interruption command, for checking the present location of the image forming medium, the feed section, the image forming section, the temporary storing section or the discharge section, and for setting up an optimum processing mode during the subsequent operation of the image forming medium on the basis of the checked result.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
343 words
A color image forming apparatus with interruption control, comprising: a color specifying section, which can selectively specify one color or a combination of colors from a plurality of prepared colors for image formation; an image data outputting section for outputting data for image formation; a supply section for supplying a medium on which an image is formed; an image forming section for moving said medium, which is supplied from said supply section, back and forth the number of times corresponding to the color and the number of colors specified by said color specifying section and for forming said image data from said image data outputting section on said medium with one or more colors specified by said color specifying section; first and second temporary storage sections, provided on input and output sides of said image forming section for temporarily and selectively storing said medium when said medium is moved back and forth by said image forming section; a discharge section for discharging said medium on which the image forming operation has been completed by said image forming section; first control means for outputting specified control signals necessary for the normal operation of said medium in relation to said supply section, image forming section, first and second temporary storage sections, and the discharge section, and for recognizing the current position information of said medium based on said control signals; interruption command section which includes at least a stop command section; second control means for discriminating whether said medium is in said supply section, image forming section, first or second temporary storage section, or in said discharge section, by receiving the current position information of said medium from said first control means which has received the interrupt command from said interrupt command section; and third control means for receiving the discrimination result from said second control means and selectively supplying a suitable interruption processing signal to said supply section, image forming section, first or second temporary storage section, and discharge section as required for each interruption processing of said medium corresponding to the discrimination result.
Claim 2
Dependent Claim
343 words
A color image forming apparatus with interruption control, comprising: a color specifying section, which can selectively specify one color or a combination of colors from a plurality of prepared colors for image formation; an image data outputting section for outputting data for image formation; a supply section for supplying a medium on which an image is formed; an image forming section for moving said medium, which is supplied from said supply section, back and forth the number of times corresponding to the color and the number of colors specified by said color specifying section and for forming said image data from said image data outputting section on said medium with one or more colors specified by said color specifying section; first and second temporary storage sections, provided on input and output sides of said image forming section for temporarily and selectively storing said medium when said medium is moved back and forth by said image forming section; a discharge section for discharging said medium on which the image forming operation has been completed by said image forming section; first control means for outputting specified control signals necessary for the normal operation of said medium in relation to said supply section, image forming section, first and second temporary storage sections, and the discharge section, and for recognizing the current position information of said medium based on said control signals; interruption command section which includes at least a stop command section; second control means for discriminating whether said medium is in said supply section, image forming section, first or second temporary storage section, or in said discharge section, by receiving the current position information of said medium from said first control means which has received the interrupt command from said interrupt command section; and third control means for receiving the discrimination result from said second control means and selectively supplying a suitable interruption processing signal to said supply section, image forming section, first or second temporary storage section, and discharge section as required for each interruption processing of said medium corresponding to the discrimination result.
Claim 3
Dependent Claim
116 words
A color image forming apparatus with interruption control according to claim 1, wherein said third control means receives the discrimination result that said medium is in said supply section from said second control means, and supplies a first interruption processing signal to said supply section, image forming section, and first and second temporary storage sections, to move said medium from said supply section to said first temporary storage section via said image forming section, second temporary storage section and image forming section without performing the image forming operation, and move said medium, which has been moved from said first temporary storage section, to said image forming section at the time of the next image forming operation.
Claim 4
Dependent Claim
71 words
A color image forming apparatus with interruption control according to claim 1, wherein said third control means receives the discrimination result that said image forming medium is in said image forming section from said second control means, and supplies a second interruption processing signal to said image forming section and discharge section, to move said medium from said image forming section to said discharge means without performing the image forming operation.
Claim 5
Dependent Claim
80 words
A color image forming apparatus with interruption control according to claim 1, wherein said third control means receives the discrimination result that said medium is in said first temporary storage section from said second control means, and supplies a third interruption processing signal to said first temporary storage section, image forming section and discharge section, to move said medium from said first temporary storage section to said discharge section via said image forming section without performing the image forming operation.
Claim 6
Dependent Claim
92 words
A color image forming apparatus with interruption control according to claim 1, wherein when said third control means receives the discrimination result that said medium is in said second temporary storage section from said second control means, and supplies a fourth interruption processing signal to said image forming section, said first and second temporary storage sections, and discharge section, to move said medium from said second temporary storage section to said discharge means via said image forming section, first temporary storage section and image forming section without performing the image forming operation.
