1. A copying apparatus that interrupts a first job during printing of the first job to allow printing by another interruption job, said copying apparatus comprising:
- an input unit for optically reading out an original image and converting the same into image data of electrical signals,a memory for storing said image data read out by said input unit,a print unit for printing on a sheet according to the image data stored in said memory,a detection unit for detecting a print wait state of said print unit when said interruption job is in progress,a first control unit for restarting printing of the interrupted said first job when a print wait state is detected by said detection unit, anda second control unit for interrupting printing of said restarted first job to initiate printing of the interruption job when cancel of a print wait state of the interruption job is detected by said detection unit.

Abstract
In an image processing apparatus, determination is made whether an interruptive print wait state is attained during interruptive printing. When determination is made that the apparatus is in an interruptive print wait state, an interruption recover process is effected. Then, the apparatus returns to the normal mode prior to interruption. Thus, an image processing apparatus is provided that can have the waiting time caused by an interruption in the normal job reduced.

6. An image formation apparatus that allows an interrupt process of a second job during execution of a first job, said image formation apparatus comprising:
-
an input unit for taking in image data corresponding to each said job, a transfer unit for transferring said image data taken in by said input unit onto a memory in advance for printing, a print unit for printing the image data transferred onto the memory by said transfer unit on a sheet, an identification unit for identifying, during a standby period of a print unit of one of said first job and said second job during execution thereof, whether execution of the other of said first job and said second job is executable, and a control unit for providing control such that said other job is executed simultaneous to said one job when identification is made that execution is possible by said identification unit. - View Dependent Claims (7, 8, 9)

10. An image formation apparatus having a reservation function that allows registration of a plurality of jobs for image formation according to a set of image data, and that initiates a print operation of a second job continuous to termination of a print operation of a first job, said image formation apparatus comprising:
-
an input unit for entering image data and an operation mode at each job, and a print unit for printing input image data on a sheet, a detection unit for detecting feeding interval of sheets fed to said print unit, and determination unit for determining whether a print operation of at least one sheet of the second job is allowed during the feeding interval of the first job detected by said detection unit, and a controller for forming an image of said second job during image formation of said first job when determination is made that printing is allowed by said determination unit. - View Dependent Claims (11, 12, 13)

14. A print method of a copying apparatus that interrupts a first job during printing of said first job to allow printing by another interruption job, comprising the steps of:
-
optically reading out an original image to convert the same into image data of electrical signals, storing said read image data into a memory, printing on a sheet according to the image data stored in said memory, detecting a print wait state of said print step during when the interruption job is in progress, restarting said interrupted first job when said print wait state is detected, and interrupting printing of said restarted first job to initiate printing of the interruption job when detection is made of cancel of a print wait state of said interruption job. - View Dependent Claims (15)

16. An image formation apparatus method of an image formation apparatus having a reservation function that allows registration of a plurality of jobs for image formation according to one set of image data, and that initiates a print operation of a second job continuous to termination of a print operation of a first job, said method comprising the steps of:
-
entering image data and an operation mode at each job, printing the input image data on a sheet, detecting feeding interval of sheets fed to said print unit, determining whether a print operation of at least one sheet of the second job is allowed during said detected feeding interval of the first job, and forming an image of said second job during image formation of said first job when said determination result indicates that printing is allowed.
