Description

[Detailed Description of the Invention] (Technical Field) The present invention stores input information such as the number of originals and the number of copies per original in a storage unit, automatically feeds the originals according to this stored information, and achieves the planned number of copies. The present invention relates to a programmable copying apparatus that automatically performs copying, and particularly to its input control method.

(Prior Art) Programmable copying devices such as those described above have been conventionally known, but in the prior art, when information such as the number of copies is inputted into the storage section, the number of remaining copies that can be made is checked using residual developed toner. Therefore, after copying has started, it is unlikely that the machine will stop due to lack of developing toner and the image quality will deteriorate.

The copying operator has to perform maintenance on the copying device each time, and the programmable copying device has the disadvantage that it cannot take full advantage of its effectiveness.

(Purpose) The biggest feature of the programmable copying machine a is that it allows the copying operator a lot of time away from the copying machine nail force.
The aim is to save labor and streamline copying operations, such as being able to engage in other tasks and managing multiple copying devices at the same time.

In view of the prior art, the present invention aims to further ensure the above-mentioned characteristics.

That is, the purpose of this invention is to prevent the copying apparatus from stopping and image quality from deteriorating due to a shortage of developing toner after the start of copying.

The unit 7 is configured to receive signals from a developing toner residue detection section 10) and the like.

This developing toner remaining detection unit] 0 is a level 411M of three sets consisting of an LED and a phototransistor, 10a, 10b,
10c. For example, this level detection section 1
0a, 10b, and IOc are provided in order from the upper blade on the side wall of the toner container (not shown). If the toner is filled, the connection between the LED and the phototransistor is cut off, and the level detection section 1. Oa, 10b, 10c
The output of the toner H1 and the number of copies that can be made can be determined by which level detection section is turned off. An example of the table is shown below.

As is clear from this table, the level detection unit 10a (a
, and so on) is off (therefore, of course, c
There is enough toner remaining (also off), and the set number of copies that can be left is 1000.

Similarly, if the level detection unit] Ob is off, 500 copies will be made, if the level detection unit 10C is off, 100 copies will be made, and if all are on, there will be no toner remaining i/Gl, and copying will not be possible. become.

FIG. 6 is a memory map of the copy information storage unit (RAM) 9 shown in FIG. are the same.

JOB (JOBI, 2) is a combination of the number of originals and the number of copies.

FIG. 7 is a copying process diagram of a programmable copying apparatus according to an embodiment of the present invention.

In the figure, the block indicated by A is the input process, and the block indicated by B
The blocks indicated by C indicate the image forming process, and the blocks indicated by C indicate the conveyance process.

To briefly explain the process, you set the number of copies and the number of originals, press the input key, and press the copy start key to start copying.
This will be changed depending on JOBi. Then, the image creation process begins, and the original side is exposed.

Development and transfer are performed, and the transfer paper side is fed and transported.

Image alignment (registration) of 1u is performed, and the unfixed image is transferred onto the transfer paper. Once the paper reaches the fixing unit and is fixed to complete the copy, it is delivered to a stacker or sorter.

Next, the present invention will be explained in detail based on FIG. 7 and FIG. 4.

In the copying work of the embodiment, the first job (IJOB) is 5 copies of a group of 5 originals, and the second job (2JOB) is 10 copies of a group of 20 documents.

First, copying information (number of originals, number of copies) must be input into the storage section of the programmable copying device.

The input method is as shown in Fig. 7.
, turn on the edge number key 311 [therefore, one copy F], and then set the number of originals using the number keys 3 b C.

Each set input information is displayed on display sections 3f and 3 in FIG.
g and JOBNO is also displayed on the display 3e. By turning on this last entry key 3C, I J OB
17J copy information is stored in the storage unit 9.
In the present invention, at this point, each level detection unit 10a of the 'fJl image toner remaining 1/detection unit 10 is detected.

(C.

P%U) 6 compares the set number of remaining copies and the total number of copies (5×5=25) from the combinations shown in the table according to the control program in the ROM 8. As a result, if the total number of copies is less than the set number of copies,
The input information is stored in the storage unit 9.

If the total number of copies is greater than the set number, the input copy information becomes invalid and is not stored in the storage section 9, and the remaining toner amount warning indicator 1a is lit.

Next, copy information for the second job is input in the same manner as described above. The input information is the total number of copies (IJOB+
2JOB) is checked.

After inputting the copy information, the copy start key 3d is turned on to start copying.

Thereafter, the copying apparatus executes a feeding and conveying process, an image forming process, and a fixing process as shown in FIG. 7 according to the copy control program stored in the control section 20R and OMB, and the copies are sorter-herited.

Thereafter, the sheets are fed and conveyed until the total number of copies (225 sheets), which is the copy information stored in the storage section 9, is used.

Image creation, fixing, and sorting are automatically and repeatedly executed.

During this time, the copying operator can leave the copying machine and attend to other tasks.

By implementing the present invention in this manner, the copying machine will not be stopped due to lack of developing toner during copying, and the copying operator can safely engage in Senjo duties or other copying machine management while copying is in progress. I can do it.

The effects of streamlining and labor-saving copying operations of the programmable copying device can be fully demonstrated.

(Effect) The present invention is as described above, and when inputting copy information to the programmable copying device a, the total number of copies of copy information in the storage unit and the power of the developing toner residue detection unit)
