Description

TECHNICAL FIELD The present invention relates to an image forming apparatus that forms an image according to an image forming mode stored in a memory.

BACKGROUND ART Conventionally, an apparatus has been proposed that stores an image forming mode in a memory and reads out the stored image forming mode at a desired time to set the image forming mode. These devices required complicated operations to memorize the image forming mode and had poor operability. Also,
If an image is formed without performing an operation to store the set image forming mode in the memory, and the user wishes to reset the image forming mode later, there is the inconvenience of having to repeat the setting operation.

Purpose The present invention has been made in view of the above points, and the present invention has been made in view of the above-mentioned points.
It is an object of the present invention to provide an image forming apparatus that can be easily reset.

That is, the present invention provides an image forming apparatus capable of forming an image in a desired image forming mode, which includes a group of mode switches for setting an image forming mode, a start switch for starting an image forming operation, and a group of mode switches described above. a first storage means for storing an image forming mode set by said start switch; a control means for executing an image forming operation according to the image forming mode stored in said first storage means upon input of said start switch; It has a plurality of storage areas in order to store image forming modes for a plurality of image forming operations based on inputs of a start switch a plurality of times, and the image forming mode is stored in the first storage means in accordance with execution of an image forming operation. a second storage means for sequentially storing the image forming modes stored in the second storage means; a recall switch for causing the first storage means to store the image forming modes stored in the second storage means; and a start switch. In response to execution of the image forming operation by the Nth input, the Nth image forming mode is stored in the second storage means, and then the N+th image forming mode of the start switch is
After the N+1 image forming mode is stored in the second storage means in response to execution of the image forming operation by the first input, when the recall switch is operated, the image forming mode is stored in the second storage means. An object of the present invention is to provide an image forming apparatus having a recall means for selecting and reading out the N-th image forming mode from among the N-th and N+1-th image forming modes and storing it in the first storage means. That is.

FIG. 3 is a flowchart of control of the copying machine sequence, etc. by the CPU 10 of FIG. 2. In FIG. 3, in step A of the flowchart, the temperature of the fixing device, the position of the optical system, the rotation of the drum, etc. are controlled from the time the power is turned on until copying is possible, and automatic shaft-off, etc. are controlled. The details are omitted.

Below, in the flowchart B, the flowchart is a preparatory stage from turning on the copy start key 212 shown in FIG. If it is OK, proceed to the flowchart. The details are omitted.

In step C of the flowchart, paper is first fed, the optical system is controlled, and a predetermined copy mode (single copy) is executed. In this flowchart, the above mode is repeated for the number of copies to be made. When the execution of the above-mentioned mode for the number of copies is completed in step A, the process proceeds to the CYEND routine for carrying out the cycle end process shown in FIG. 4-a in step B.

FIG. 4-a shows a flowchart of the CYEND leatin. Note that the program of the CPU 10 may proceed to the CYEND routine when the copy stop key 207 in Fig. 1 is pressed in flowcharts I, B, and C in Fig. 3, or when the execution of the copy mode ends. . In Fig. 4-a, in step (), the normal copy sequence is completed, and in step (), the contents of the contemporary buffer (described later) are transferred to the recall buffer, and the contents of the current buffer are transferred to the contemporary buffer. Perform the task of transferring.
Details will be explained in FIG. When the above operations are completed, the process returns to step B of the main routine flowchart shown in FIG.

Figure 4-b shows that when the recall key 206 in Figure 1 is pressed, the program of the CPU 10 advances.
This is a flowchart of the REC ALL routine.
In the RECALL routine, the contents of the recall buffer are transferred to the current buffer, and the process returns to the main routine of FIG. The details will be explained in FIG. 5.

Figure 5 shows the CPU used to store copy setting conditions.
10 is a diagram showing a plurality of areas reserved on the RAM of No. 10 and the flow of data between these areas, and is a diagram showing the structure of a data table. FIG. Hereinafter, FIG. 5 will be explained with reference to FIG. 4-a and FIG. 4-b.

The current buffer is an area where copy conditions set using the numeric keypad and various function keys are first stored, and the copy sequence program directly uses (Read/Write) this data to proceed with the job. The copy sequence executes cycle end processing depending on whether the specified number of copies have been completed or whether the STOP key is pressed in the middle. At this time, the contents of the contemporary buffer 501 are transferred to the recall buffer 503 and the current buffer is The contents of the buffer 502 (the number of copies returns to the initial value when copying is completed; the number remains unchanged when the STOP key is pressed) is transferred to the contemporary buffer 501.

Therefore, the contemporary buffer 501 always stores the last copy condition, and the recall buffer 503 always stores the last copy condition. Here, FIG. 1 206
When you turn on the recall key, recall buffer 5
The contents of 03 are transferred to the current buffer 502. Therefore, the copy mode from one cycle before is called up again and set, and copying can be performed using the copy mode from one cycle before. Similarly, if the recall buffer 503 is not recalled, the contents of the recall buffer 503 are removed by cycle end processing, and the contents of the contemporary leaf buffer 501 are stored in the recall buffer 503, making it possible to always remember the copy mode of one cycle before. It is becoming.

In this embodiment, only the copy conditions from one copy cycle ago are stored, but if they are always updated one by one and called out to the cycle recall by the recall key, they can be used as multiple recalls. .

Effects As explained above, according to the present invention, the image forming mode set by the mode switch group is changed to the first image forming mode.
In an image forming apparatus that forms an image according to the stored image forming mode, the Nth image forming mode changes to the second image forming mode in response to execution of the image forming operation by the Nth input of the start switch. is stored in the storage means of the start switch, and then the N+th
After the N+1 image forming mode is stored in the second storage means in response to the execution of the image forming operation by the first input, when the recall switch is operated, the N+1 image forming mode stored in the second storage means is stored. , by selecting and reading out the N-th image forming mode from the N+1-th image forming mode and storing it in the first storage means, the image forming mode of the executed image forming operation can be changed without any special operation. Even after executing the next image forming operation using the start switch, image formation can be easily performed in the image forming mode of the previous image forming operation.
