Abstract

PURPOSE:To prevent copying error and to eliminate the procedure of confirming the existence of an original. CONSTITUTION:Two types of original setting means 1d and 2 are provided to the device. Sensors 7 and 8 detecting the existence of the original 4 are provided to each original setting means 1d and 2. A control means 9 is provided to control setting of priority of each set original 4 based on signals from each sensors 7 and 8 and to copy the original 4 following that priority. Therefore, although when originals are conventionally set to a multiple number of original setting means, there was generation of copying error where copying cannot be carried out when copying is attempted, the priority can be set against each original 4 set to each original setting means 1d and 2 in this constitution.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a copying machine having a plurality of document setting tables (or document setting means).

[0002]

2. Description of the Related Art Conventionally, as a copying machine as described above, an automatic document feeder (or original document feeder) as a document setting means (or
A recirculating document handler) is known, and such a copying machine has an automatic mode and a manual (platen) mode to detect the presence or absence of a document on the document setting table for the platen. If the sensor is not provided, you cannot copy in the platen mode as long as the original is set in the automatic document feeder,
Further, when both the automatic document feeder and the platen are provided with the document detecting means, the automatic (ADF) mode is set not to be set if there is a document on the document setting table for the platen.

[0003]

However, in the above-mentioned conventional configuration, when there is a document in both the automatic document feeder and the platen, if one of the documents is tried to be copied without being removed, it becomes impossible to copy. Since a miscopy may occur, it is necessary to remove one of the originals before copying the other original. Therefore, it is necessary to always check whether or not there is a document on both sides, which causes a problem that it takes time to copy.

[0004]

In order to solve the above problems, a copying machine according to claim 1 of the present invention is provided with a plurality of document setting means for setting a document, and based on a copy signal from the input means. In the copying machine for copying the set original, the original detecting means for detecting the presence or absence of the original in each original setting means are respectively provided, and the plurality of originals set based on the signals from the respective original detecting means. Is provided with a control means for setting the copy processing priority and controlling to copy the highest priority document.

In order to solve the above problems, a copying machine according to a second aspect of the present invention is the copying machine according to the first aspect, in which the control means is set to sequentially copy an original document in accordance with the copying processing priority order. It is characterized by being.

[0006]

According to the above-mentioned structures of claims 1 and 2, for each document set in each of the plurality of document setting means, based on the signal from each document detecting means,
For example, the control unit can set the copy processing priority order of each document by using the time difference of setting each document.

Therefore, when a plurality of originals are set, the original to be copied is set preferentially by the copy signal from the input means, so that the conventional miscopy is avoided.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The following will describe one embodiment of the present invention with reference to FIGS. In copiers,
As shown in FIG. 2, a main body 1 having a substantially rectangular parallelepiped shape is provided,
A document set table (not shown) made of a glass plate that allows light to pass therethrough is provided on the upper surface of the document set table (not shown) for exposing the placed document (not shown) to light. A box-shaped original circulation type automatic feeder (original setting means) 2 and an original cover 3 as a plate-shaped original cover are arranged side by side.

Further, a horizontally elongated operation panel 1a having a substantially rectangular shape is installed at the front part of the upper surface of the main body 1 to set the number of copies and copy density, and the start of copying is instructed at the right end of the operation panel 1a. Therefore, the print switch 1b is provided as an input unit.

The document circulating type automatic feeder 2 is provided with a document tray 2a at the left end thereof, and as shown in FIG. 3, one or a plurality of documents 4 set on the document tray 2a are automatically fed one by one. The document 4 is sent out onto the first document setting table 1c, which is the left half of the document setting table facing the lower bottom surface thereof, and after exposure, the document 4 returns to the lower part of the document tray 2a.

Further, the original cover 3 is arranged so that it can closely adhere to and cover the upper surface of the second original setting table (original setting means) 1d which is the right half of the above-mentioned original setting table facing the lower bottom surface thereof. It is possible to fix the document 4 which is provided and is set on the second document setting table 1d so as to be brought into close contact with the second document setting table 1d. Therefore, by using the original cover 3, it is possible to read the original 4 more clearly. Here, the document setting means means a functional part that is on standby for copying a document.

On the other hand, in the main body 1, each original setting table 1c.
Scan the document 4 placed on them below 1d,
An optical system 6 for exposing and forming an electrostatic latent image on the photosensitive drum 5 at a desired magnification is installed.

This optical system 6 has an automatic operation position for exposing the original 4 on the first original setting table 1c below the original circulating automatic feeder 2 and a second original set below the original cover 3. A manual operation position for exposing the original 4 on the table 1d is provided, and these positions are position-switched and controlled according to an automatic mode and a manual mode which are exposure modes.

The document tray 2a of the document circulating automatic feeder 2 detects the presence of the document 4 in the document tray 2a.
A sensor (original detection means) 7 is installed, and separately below the second original setting table 1d in the main body 1, a second sensor for detecting whether or not the original 4 is set on the second original setting table 1d. (Document detecting means) 8 is installed. Although optical sensors are used as these sensors 7 and 8, a weight sensor that detects weight may be used as the first sensor 7.

As shown in FIG. 1, these sensors 7 and 8 are connected to a CPU (Central Pro
When a document 4 is detected in the document circulating automatic feeder 2 and the original cover 3, it is connected to a control unit 9 including a cessing unit) and sends a pulse signal indicating the detection to the control unit 9.

The control means 9 processes the above-mentioned pulse signal according to the processing procedure which will be described later and is set in FIG. 3 based on the signal from the print switch 1b as the input means.
The document circulation type automatic feeder 2 and the optical system 6 are controlled. A storage unit 10 such as a memory is connected to the control unit 9 for such processing in the control unit 9.

Next, the operation after the start-up operation in the above copying machine will be described. First, as shown in FIG. 4, the original 4 is set on the original tray 2a of the automatic circulating automatic feeder 2 and On the other hand, as shown in FIG. 5, the original cover 3 is opened, and the original 4 is set on the second original setting table 1d.

Therefore, in the control means 9, as shown in the block diagram of FIG. 1 and the flowchart of the original selection routine of FIG. 6, for example, when the second sensor 8 as the second original detection means is turned on (step 1, Hereinafter, the step is abbreviated as S), the state of the first sensor 7 as the first document detecting means is checked (S2), and when the first sensor 7 is off, that is, the document tray as the first document setting means. Two
When the document 4 is not detected in a, the manual mode in the exposure mode is operated as it is based on the signal from the print switch 1b as the input means (S5).

On the contrary, when the first sensor 7 is turned on, it is assumed that the original 4 is set in the original circulating automatic feeder 2 first, and the manual mode is set as the interrupt mode (S
3) Store the mode that has been set up to that point, that is, the automatic mode, in the storage means 10 that is a predetermined memory (S
4) Set the manual mode (S5). Then, the second
When a copy signal is input from the print switch 1b for the document 4 set on the document setting table 1d (S6),
Copying is executed in the manual mode (S7).

Although the flow chart shown in FIG. 6 is not shown below, the control means 9 checks the state of the second sensor 8 when the first sensor 7 is turned on, and the second sensor When 8 is off, the document circulation type automatic feeder 2 is driven and controlled as it is in the automatic mode, and the document tray 2 is driven based on the signal from the print switch 1b.
The originals 4 a are sent one by one onto the first original setting table 1 c and copied.

On the other hand, when the second sensor 8 is turned on, first,
Assuming that the original 4 covered by the original cover 3 as the second original setting means 3 is set on the second original setting table 1d, the automatic mode set later is set as the interrupt mode, and the setting is performed until then. After the stored manual mode is stored in the storage means 10 which is a predetermined memory, the control means 9 drives and controls the document circulation type automatic feeder 2 as the automatic mode, and based on the signal from the print switch 1b, The originals 4 on the original tray 2a are copied one by one.

When a series of copying is completed in this way, if there is an interrupt mode, it is considered that the interrupt mode has ended after a predetermined time, the interrupt mode is reset, and the mode previously stored in the memory means 10 is stored in the memory. To place the original 4 in that mode on standby for further processing. At this time, the control means 9 is set such that the modes stored in the storage means 10 are sequentially processed, for example, the modes stored later are processed first so that the originals 4 can be sequentially copied. It is also possible to do so.

As described above, in the configuration of the above-described embodiment, for example, the respective originals 4.4 are set with respect to the originals 4 and 4 set on the original circulating automatic feeder 2 as the original setting means and the original cover 3, respectively. Based on the signals from the respective sensors 7 and 8 as the document detecting means, the control means 9 sets the copy processing priority of each of the originals 4 and 4, that is, it is set from the latest after the set time shift of A priority order is set such that the original 4 is copied first, and the original 4 is copied based on the priority.

By the way, when a plurality of document setting tables or document setting means are provided as described above, conventionally, the documents are set on both the automatic document feeder as the document setting means and the platen as the document setting table. While trying to make a copy without removing one of the originals, a copy error occurred.

Therefore, in the above-mentioned conventional method, when the originals are set on both sides, it is always necessary to remove one of the originals and then copy the other original, so that there is always no original on both sides. I had to make sure that it was time-consuming to copy.

However, in the structure of the above-described embodiment, the miscopy as in the prior art is prevented in advance. Therefore, unlike the prior art, the time and effort for copying after always checking the presence or absence of the original in each original setting means is omitted. be able to.

In the above construction, an example in which two document setting means are provided is shown, but a plurality of three or more document setting means are provided and each document setting means is provided with a sensor as a document detecting means. If installed, the control means 9 appropriately prioritizes based on the signals from those sensors, for example, the document set at the latest is copied first.
Priority can be set with IFO (Last In First Out),
Each original 4 can be set to be copied based on the priority.

[0028]

As described above, the copying machine according to the first aspect is provided with a plurality of document setting means for setting a document.
In a copying machine for copying an original set based on a copy signal from the input means, original detection means for detecting the presence / absence of an original in each original setting means are respectively provided, and based on a signal from each original detection means. Then, a control means is provided for setting the copy processing priorities of the plurality of set originals and controlling so that the highest priority original is copied.

As described above, the copying machine according to a second aspect of the present invention is the copying machine according to the first aspect, wherein the control means is set to sequentially copy the original document according to the priority order of the copying process. It has a structure.

Therefore, in the configurations according to claims 1 and 2, the copy priority order is set for each document set in each of the plurality of document setting means, for example, based on the set time of each document. Can be set. Therefore, conventionally, when a copy signal from the input means is input when the originals are set in the plurality of original setting means, a copy error occurs, which makes copying impossible. It is possible to prevent the miscopy that has occurred.

As a result, each of the above-mentioned configurations has an effect that it is possible to save the labor of copying, which is required to always check the presence or absence of a document in each document setting means as in the conventional case.
