Abstract

PURPOSE:To enable copying operation to be processed only when an intended copying form is inserted by providing a means starting copying operation, a control means permitting the control means to start copying operation and a control means holding a standby condition continuously. CONSTITUTION:A copying machine is provided with a feed roller 3 feeding a copying form inserted by hand into the machine, a hand insertion detecting switch 2 detecting the copying form to be inserted by hand in front of the aforesaid roller, and with a copying action control section 33 starting the operation of the copying machine including the drive of the feed roller 3. The copying machine is also provided with a machine condition judging section 31 which permits the copying action control section 33 to start copying operation when the copying form is detected in a state that the copying form is not detected by the hand insertion detecting section 2, but does not permit the control section to start copying operation even when the copying sheet is detected by the hand insertion detecting switch 2 provided that a specified condition is not satisfied, and holds a standby condition continuously as directed by a standby time control section 32 keeping the machine waiting. By this constitution, copying operation can thereby be automatically processed only when the intended copying sheet is inserted.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a copying apparatus having a manual paper feeding function.

2. Description of the Related Art In recent years, as copying machines have become more sophisticated, the number of low-cost, popular models has been increasing. Most of the popular copying machines are equipped with two paper feed sources, a cassette and a manual paper feed source, and also have a function of automatically copying paper that is manually inserted.

An example of the above-mentioned conventional copying apparatus will be described below with reference to the drawings. FIG. 3 is a schematic diagram of a conventional copying apparatus in the vicinity of manual paper feed, and FIG. 4 is a flowchart of manual automatic copy start control for automatically copying manually inserted copy paper.

In Fig. 3, 1 is a manual feed tray for holding manually inserted copy paper, 2 is a manual feed detection switch for detecting manually inserted copy paper, and 3 is a manual feed detection switch for feeding the manually inserted copy paper into the machine. 4 is a timing roller for temporarily stopping the copy paper fed by the paper feed roller 53; 5 is a timing roller 4;
A paper feed completion switch located in front of the paper feed roller 3 detects the leading edge of the copy paper fed by the paper feed roller 3 and stops it with the timing roller 4. 6 is a photoreceptor drum, which is used for scanning by an optical device (not shown). A xerographic image obtained in a copying process including operation is formed, and the timing roller 4 is moved at a timing when the copy paper waiting on the timing roller 4 and the xerographic image formed on the photosensitive drum 6 are synchronized.
The copy paper is then conveyed, and the processes of transfer, separation, and fixing (not shown) are executed.

Furthermore, if the paper feed completion switch S does not detect copy paper within a predetermined time after the paper feed roller 3 starts conveying the copy paper, it is determined that a paper jam has occurred and all operations of the copying device are stopped. The system is designed to notify the user.

With respect to the electronic copying apparatus configured as described above, a control method for automatically performing a copying operation on manually inserted copy paper will be described below with reference to FIG.

First, it is determined whether or not copying is possible (step 10). If the machine is in an impossible state, such as when a mechanical abnormality occurs or the front door is opened, the manual automatic copying start processing is terminated without performing any subsequent processing. Further, if it is possible to accept copies in step 10, it is determined whether the manual feed detection switch 2 has detected copy paper (step 11), and if the manual feed detection switch 2 has not detected copy paper, the same process is performed. Then, this manual automatic copying start processing is ended without performing any subsequent processing. Further, when the manual feed detection switch 2 detects copy paper, it is determined whether fixing preparation is complete (step 12). Here, if the fixing temperature has not reached the copying operation-enabled temperature, it means that preparation is in progress, and subsequent processing is not performed, and the second manual feed automatic copying start processing is ended. If the fixing temperature has reached the copying operation temperature in step 12, the process advances to the next step (step 13), where the copying operation including the manual paper feeding is started to copy the manually inserted copy paper. It automatically feeds paper and performs copying operations.

Problems to be Solved by the Invention However, in the above configuration, the manual feed detection switch 2 detects copy paper when copying is possible, and if the fixing preparation is completed, the copying operation is automatically performed. If the electronic copying machine starts copying as soon as a paper jam is removed and the front door is closed with paper manually inserted, or if the power switch is turned on with copy paper manually inserted, the Copying operations may occur that the user does not intend, such as starting a copying operation at a time when the user does not intend to do so, which not only wastes copy paper, but also poses a danger if the copying device starts copying at a time that the user does not intend. There were issues such as:

In addition, if the manual feed detection switch 2 is malfunctioning and is constantly detecting copy paper, manual paper feed will be performed as soon as the power is turned on and fixing preparations are completed, and there will be no copy paper, so the paper will be fed manually. The paper completion switch 5 determines that the copy paper is jammed. Therefore, if the manual feed detection switch 2 fails, even if there is a paper feed source different from the manual feed, there is also a problem in that copying operations using a normal paper feed source are no longer possible.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to provide a copying apparatus that prohibits unintended copying operations by the user and minimizes damage caused by failure of the manual feed detection switch.

Means for Solving the Problems In order to solve the above problems, the copying apparatus of the present invention includes a paper feed roller for feeding manually inserted copy paper into the machine, a paper feed roller located in front of the paper feed roller, and a manual feed roller. a manual feed detection switch for detecting inserted copy paper; a control means for starting the operation of the copying machine including driving the paper feed roller; and a manual feed detection switch for detecting copy paper when copying is possible. A control means for causing the control means to start a copying operation when copying paper is detected from a state where it is not detected, and a standby state is continued without starting the copying operation when the manual feed detection switch detects copying paper under conditions other than the above-mentioned conditions. control means for controlling the

According to the above-described configuration, the control means starts the copying operation when the manual feeding detection switch detects a copying paper from a state in which copying paper is not detected in a state in which copying is possible, and manual feeding is performed under conditions other than the above-mentioned conditions. By continuing the standby state without starting the copying operation when the detection switch detects copying paper, the copying operation is automatically performed only when the copying paper is manually inserted by the user while the copying operation is ready. will be carried out.

In addition, if the manual feed detection switch fails, the copying operation does not occur automatically and the printer goes into a standby state, so the copying operation can be performed using another paper feed source using the copy start switch.

Embodiment Hereinafter, a copying apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a control block diagram of a copying apparatus in an embodiment of the present invention.

In FIG. 1, 30 is an input section including various sensors;
32 is a standby control unit that controls the standby state of the electronic copying device; and 33 is a copying device that controls the copying operation of the copying device. The operation control section 34 is an abnormality control section that controls the state of the copying apparatus in the event of a paper jam or a mechanical operation error, and is selected by the machine state determination section 31. 35 is an output section driven by each state control section 32 to 34 of the copying apparatus.

The automatic copying operation of manually inserted copy paper in the copying apparatus configured as described above will be described below with reference to FIGS. 1, 2, and 3.

First, FIG. 3 is a schematic diagram of the vicinity of the manual paper feed of the copying machine, which is the same as that described in the related art.

FIG. 2 is a flowchart of automatic manual copying start control for automatically copying manually inserted copy paper;
The same reference numerals as in FIG. 4 indicate similar processing.

First, it is determined whether copying is possible or not (Step 10). If the machine is in an impossible state such as an abnormality occurring or the front door being opened, the flag is reset (Step 15), and the manual automatic copying start process is ended. Furthermore, if it is possible to accept copies in step 1o, it is determined whether the manual feed detection switch 2 has detected copy paper (step 11), and if the manual feed detection switch 2 has not detected copy paper, a flag is set. Finally, in step 16), the manual automatic copying start process is ended. Further, when the manual feed detection switch 2 detects copy paper, it is determined whether fixing preparation is complete (step 12). Here, if the fixing temperature has not reached the copying operation-enabled temperature, it means that preparation is in progress, and the subsequent processing is not performed, and this manual automatic copying start processing is ended. In addition, if the fixing temperature has reached the copying operation temperature in step 12, the next step (
Proceed to step 14), where the state of the flag is determined. If the flag was reset in step 14,
This manual automatic copying start processing is ended without performing any subsequent processing. If the flag is set, the flag is reset (step 17), and then the manually inserted copy paper is automatically fed and a copying operation is performed (step 13).

In other words, a flag is set that is set when it is confirmed that there is no copy paper inserted manually when copying is possible, and only when the manual feed detection switch 2 detects copy paper with this flag set, manual insertion is performed. The system automatically starts copying the copied paper.

As described above, according to the present embodiment, there is a paper feed roller 3 for feeding the manually inserted copy paper into the machine, and a roller for detecting the manually inserted copy paper located in front of the paper feed roller 3. a manual feed detection switch 2, a copying operation control unit 33 for starting the operation of the copying machine including driving the paper feed roller, and a state in which the manual feed detection switch 2 does not detect copy paper when copying is possible. A standby control unit 32 causes a copying operation control unit 33 to start a copying operation when a copy sheet is detected from the source, and continues a standby state without starting a copying operation when a manual feed detection switch detects a copy sheet under conditions other than the above conditions. By providing a machine state determination section 31 for continuing the standby state, it is possible to automatically perform a copying operation only when a copy sheet is manually inserted as intended by the user during a state where copying is possible.

Effects of the Invention As described above, the present invention includes a paper feed roller for feeding manually inserted copy paper into the machine, and a manual feed roller located in front of the paper feed roller for detecting the manually inserted copy paper. a detection switch, a control means for starting the operation of the copying machine including driving the paper feed roller, and when the manual feed detection switch detects copy paper from a state in which copy paper is not detected when copying is possible; By providing a control means for causing the control means to start a copying operation, and a control means for continuing a standby state without starting the copying operation when the manual feed detection switch detects copy paper under conditions other than the above conditions, a copy acceptance ready state is provided. Sometimes, the copying operation can be performed automatically only when the copy paper intended by the user is manually inserted.

In other words, if the copying operation starts as soon as a paper jam is removed from the copying machine and the front door is closed with copy paper inserted manually, or if the power switch is turned on with copy paper inserted manually, It is possible to prohibit a copying operation that is not intended by the user, such as starting a copying operation immediately, and to prevent the wastage of copy paper and danger to the user due to copy mistakes.

In addition, if the manual feed detection switch malfunctions and it is constantly detecting copy paper, and if there is a paper source other than the manual feed, it is possible to make copies using that paper source. can.

Furthermore, the present invention has the advantage that it can be implemented by using exactly the same components as the conventional manual paper feeder and with only slight changes in the control method.
