Determination is made as to whether a vendor (an apparatus which allows use of a copying machine according to the value of any money entered) is connected to a copying machine having a power supply to be controlled. If the vendor is connected to the copying machine, an automatic power off function is inhibited. When the power supply is turned off, if any coin is entered in the vendor, the supply is automatically turned on.

In a copy machine which is one type of an image forming apparatus, a job out of a plurality of jobs to be displayed on a display is selected according to a state of the copy machine and an operation towards the copy machine. When the copy machine is currently carrying out an operation, either a print operation or a read operation is selected with the read operation having a higher priority. When an error occurs resulting in of the copy machine being halted, the job causing the error is selected. When the copy machine currently attains a stop state, a predetermined setting carried out by the operator with respect to the copy machine is selected. The selected job is displayed on the display as the current job which is a job of the operator. Since the operator can identify the contents of the job according to the state of the copy machine, an image forming apparatus with a multi-job function is provided that can be easily handled by the operator.

Image forming apparatus that facilitates operation setting

A copy machine can store image data corresponding to a plurality of original groups. The user can carry out an editing process such as confirmation, erasure, and modification, and the like on the stored image data. A control unit of the copy machine provides control so that, when printing of a previous job has ended, and the mode to confirm, erase or modify the image data of a registered original group is not selected, printing of a next job is initiated if there is a job to be printed out. When the edit mode is selected, the control returns to the main routine. Therefore, printing of a job subsequent to the job that has been ended will not be initiated. Thus, a copy machine can be provided that can appropriately process image data of a registered original group.

A user sets a function of corner stapling, two-point stapling or punching on an operation panel of a copying machine, as a process for a paper after copying. Then, the copying machine determines whether or not a function of folding the paper after copying is set, for setting a position for corner stapling, two-point stapling or punching on a portion suitable for each folding method. The user can set the paper folding function and the stapling or punching function in a combined manner, and the facility of the copying machine is improved.

Image forming apparatus capable of a plurality of processes on sheet

An image forming apparatus is capable of performing a plurality of processes for a sheet provided with an image such as stapling and punching. When two different processes are set together, the image forming apparatus displays a particular screen for making a user select positions for these processes. Thus, the incidence of setting errors can be reduced when the user sets the two processes in combination with each other.

Image forming apparatus capable of executing a plurality of processes at

An image forming apparatus capable of simultaneously performing an image forming operation of a first job and an image reading operation of a second job wherein the jobs comprise a plurality of sheets. The apparatus has a controller which continues the image reading operation of the second job even when the image forming operation of the first job is stopped, and prohibits the start of an image reading operation of a third job different from said first and second job when the image reading operation of said second job ends.

Image forming apparatus having simultaneous reading and printing

A copying machine according to the present invention having a multi-job function can perform processing to a current job and a sub job, and errors are divided into two stages. If a high level error occurs in a job processed as the sub job, the job is switched to the current job, and the error is widely displayed on the entire display portion. If a low level error occurs in a job processed as the sub job, the error is displayed in a small sub job display portion in the display. As a result, the user can be accurately informed of an error occurring in the sub job in the copying machine.

Image forming apparatus informing internal abnormality

A copying machine is provided capable of readily and conveniently setting a User's Choice value for an additionally set division. In the copying machine, the User's Choice value of the system which is set for each division is stored in a rewritable storage, such as a hard disc, a back-up memory or the like. The User's Choice of the system is changed in a control unit of the copying machine. The User's Choice value of the system is used as default in registering a new division, and it is thus not necessary to conventionally set a new User's Choice value based on the User's Choice value of the system which is stored in a ROM and thus cannot be changed. Thus, setting User's Choice values is no longer cumbersome for users, and the users can readily and conveniently set User's Choice values for an additionally set divisions.

In a copying machine according to the invention, a plurality of jobs are read and registered, and printing and reading of thus registered jobs can be independently performed. In the copying machine, if printing is stopped during printing a job registered under number 4, for example and it is highly probable that the estimated ending time for printing of jobs under job numbers 4 and 5 will be changed, the estimated ending times for these jobs are displayed in dots unlike the normal display. As a result, the user can be informed that an estimated time for the end of printing for a certain job becomes inaccurate.
