Abstract

PURPOSE:To discriminate and classify original sheets without use of any sorter nor a slip-in tray designed solely therfore, by using one of the recording sheet feed trays as slip-in trays, and by transporting slip-in sheets during copying of original sheet intermittently using a control circuit. CONSTITUTION:When copying is started, a control signal is emitted by a CPU22 to an input/output circuit 25 for control of a transport roller 26, scanning 27 and recording mechanism 28, and now copying is made to recording sheets K3, which are exhausted to an xhaust tray Th one after another. At the same time the number of sheets copied is counted, and when desired number N is attained the operation shall be finished. Before the N is counted, the number of slipped-in sheets n is counted, and a control signal is sent to the input/output circuit 25 to control drive of roller 1, and stop of roller 2, scanning and recording operation. Here slip-in sheet Ks for the tray T1 is free from recording by drum 3 and exhausted as the n+1'th copy sheet, when no counting will be made, and the copying shall be interrupted if the desired number N is counted up after every n'th sheets K3 being copied. The copied sheets are grouped and identified by slip-in sheets.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is provided with a plurality of recording paper supply trays and one paper output tray, and the present invention is provided with a plurality of recording paper supply trays and one paper output tray, and it is possible to sort the same copy paper every predetermined number of sheets without using a sorter. The present invention relates to a copying machine that can easily identify different types of copy paper.

[Prior art]

When loading a plurality of recording paper supply trays, each using recording paper of different sizes, and obtaining a predetermined number of copies of the same or different types, the same copy paper is divided into several copies. Or, in order to sort different types of copy paper by type, it was common to use a sorter. However, the sorters are generally expensive and subject to restrictions on installation location. For this reason, a copying machine as shown in Fig. 1 was proposed as a Zen copying machine that can sort the copy sheets without using the sorter, and it has not been put into practical use.
was. In Fig. 1, T1, Tt, N, and Z9 are printed on g self-recording papers of different sizes,, K! TS is the recording paper supply tray loaded with 8, TS is the insertion paper supply tray in which 8 is loaded, Th is the paper output tray, ], 2it Kirin paper conveyance roller, 3 is the recording drum, 4I"i fixing unit , 5
1 is a cutting progress guide plate, 6 is a paper discharge roller, 7 is an insertion paper transport roller, 10 is an operation panel, and 20 is a control section. In this apparatus, when, for example, +e is used for recording paper to make 10 identical copies, the same copying paper is divided into two sheets in the following manner. First, by operating a 10Ω predetermined switch on the operation panel, the following information is set on the recording paper: selection, same copy, division into two copies, and 10 copies, and then the start switch is turned on to begin copying.

As a result, the conveying roller 1 is rotated, and the recording paper 1 is sequentially conveyed through the conveying path ζn1, and is transferred and recorded by the recording drum 3. After being heated and fixed in the constant difference section 4, the sheet is discharged by the paper ejection roller 6.
The paper is ejected to the paper ejection tray Th. Similar to this, when the second copy is ejected to the paper output tray 6, the switching guide plate 5 will appear in the state shown by the dotted line. can be switched to At the same time, the inserted paper transport roller 7 starts rotating ζn2.
The paper is ejected onto the two sheets of paper that were already ejected in h.

Here, since the insert paper is of a different color or size than the recording paper, it is easy to distinguish it from the two recording papers. Thereafter, the same control as described above is repeated according to the set command contents, and when the number of copies reaches 10, the entire operation is completed. At this time, an insert paper is inserted into the paper output tray Th every two sheets f' to obtain 10 +=-sheets, which simplifies the subsequent sorting process of the sheets. .

In addition, when obtaining a predetermined number of copies of different types of originals using the recording paper, in order to classify the copying paper by type, the switching guide plate 5 is , the inserted paper conveyance roller 7 is driven to eject 8f of the inserted paper each time. The above control could also be performed in the same way when recording paper Kt was used. However, in such conventional copying machines, there is an independent tray for loading insert sheets to be inserted between each copy sheet in order to sort the same copy sheets or different types of copy sheets of the above-mentioned recording sheets in a desired manner. Since the recording paper is provided and the recording paper is controlled to be ejected through a path different from the conveyance path of each of the recording sheets, 1. The structure of the apparatus becomes complicated and the external shape becomes narrow.

2. Cost increases.

3. It is wasted if it is used infrequently.

There were other drawbacks.

[Purpose of the invention]

The present invention has been devised to eliminate the above-mentioned drawbacks, and allows arbitrary sorting and identification of copies of the same copy paper or copies of different types using a simple structure as possible without using the sorter or a dedicated supply tray for insert paper. The purpose of the present invention is to provide a copying machine that can be easily used.

[Structure of the invention]

Therefore, in the present invention, one of the conventional recording paper supply trays is
is brought into contact with the insert paper supply tray, and while the desired original is being copied, the insert paper is intermittently conveyed under the control of a control circuit added to the Shintomo, and the original is copied onto the insert paper at this time. The paper is ejected to the ejection tray without being installed, so that the above function can be achieved without installing a sorter.

[Embodiments of the invention]

Embodiments of the present invention will be described in detail below based on the accompanying drawings. FIG. 2 is a plan view of a schematic configuration of a two-tray type copying machine for supplying recording paper, showing an embodiment of the present invention. Components that perform the same functions as the conventional device shown in FIG. 1 are designated by the same reference numerals. It is marked. This copying machine has a configuration in which the special tray for inserting and feeding paper has been removed from the mechanism of the conventional device, and an operation control section consisting of an operation panel 1 with new functions and a control circuit section 12 has been installed. It has become. Here, the operation panel 11 has an external structure as shown in 3(9)I(a), for example, and includes a keyboard 12, a number display section 13,
A start switch 14, an insertion switch 15, and an identical original switch 16 are provided. Then, by turning on or off the insertion H switch 15, it is possible to select whether or not to insert an insertion sheet into the copy paper, that is, whether or not it is necessary to identify an arbitrary unit of copy paper. By turning on or off, it is possible to select whether to continuously sort the same copy paper into arbitrary numbers or to intermittently sort different types of copy paper by type. In addition, the control circuit section 21 is configured as shown in FIG. Ilo
)25. The v025 is connected to the twisted conveyance roller drive section 26, the scanning drive section 27, and the recording mechanism drive m28. Here, the CPU 22 exchanges information with the cheetah program 24 according to commands given from the keyboard 12 in accordance with the programs necessary for copying stored in the program memory 23, and sends various control signals to 11025 to execute copying. In addition, the recording paper supply tray T
, an insertion paper K having a different color and size from the recording paper Ks loaded in the Fi recording paper supply tray T is carbon-loaded, and recording is performed under the control of the control circuit section 21 based on a predetermined operation of the operation panel 11. Paper transport roller J
By intermittently driving the insert paper Kf
The paper can be ejected to the paper ejection tray Th.

The operation of the copying machine will be described in detail below with reference to the flowchart shown in FIG. First, the operator turns on a power switch (not shown) to make the copier ready for operation (step 4013).
．． Next, predetermined operations such as tray selection are performed so that the recording paper Ks can be used for copying, and the insertion switch 15 is turned on or off depending on whether identification of the copy paper is required to complete copying (step 402) - If identification of said copy paper is required, said plug-in switch 15
Turn on f and then keyboard 12? The operator sets the number n of sheets to be inserted into the insertion sheet according to how many sheets of copy paper is desired to be inserted (step 403). Here, the number n of sheets is stored in the data program 24 (step 404). Furthermore, the same original switch 16 is turned on or off depending on whether the copy sheets sorted every n sheets are the same original or different types of originals (step 405).

If it is the former, the same document switch 16 is turned on and the desired total number of copy sheets N (n≦N) is set (step 406). The number N is also stored in the data memory 24 (step 407). At this point, the start switch 14 is turned on for the first time to start copying (step 408.4Q9).
A control signal is sent to O25, and the control output of I10 causes the conveyance roller drive unit 261. Scanning drive section 27
, the recording mechanism drive section 28 is controlled, the n roller 2 is driven, and scanning and recording operations are started. This,
From the VC, the recording sheets Ks pass through the above-mentioned conveyance path, are copied, and are sequentially discharged to the paper discharge trays Th&C. At the same time, the CPU 22 counts the number of copies and compares the counted number with the desired number N1 of inserted sheets n stored in the data memory.

Here, if the desired number N is counted, the operation is immediately stopped and copying is completed (step 410);
Furthermore, if the number of inserted sheets n is counted before the desired number N is counted (step 411), the previous 8 CPU
A control signal is sent from 22 to I1025, and
The control output controls driving of roller 1, stopping of roller 2, stopping of scanning, and stopping of recording operation (step 412).

Here, the inserted paper 8 loaded in the recording paper supply tray T1 passes through the same conveyance path as the recording paper 3 without being recorded by the drum 3, and reaches the paper output tray T h K n + The paper is ejected as the first copy sheet. At this time, the CPU 22 suspends the function of counting the number of copies and does not count the inserted sheets Ks. Thereafter, the above-mentioned operations are continued until the CPU 22 counts up the desired number Nf of n sheets of recording paper Ks, and when the count-up is reached, all the above-mentioned operations are stopped and copying is completed (step 410).

At this time, the paper output tray ThK is loaded with n sheets of paper Ks.
8 sheets of the same copy paper are obtained by inserting the paper, and subsequent sorting of the copy papers can be easily performed. ,
The drive control of the above-mentioned conveyance rollers and 2 can be realized, for example, by using one step motor and driving the step motor in reverse. By the way, in step 405, if the desired copy paper is of a different type, and an attempt is made to identify it by type, the number of sheets to be inserted is set in @, and then the original switch]6! ″J Immediately step 4 without turning on
Moving to step 13, the start switch 14 is turned on to begin copying (4) 4) The transport roller 2 is driven by the e-pull, and copies of 1 are sequentially made on the recording paper in the same manner as described above.

At this time, the CPU also counts the number of copies, and when the counted number reaches nK (step 415), l1025
Then, the control signal tube is sent out, the scanning operation, the recording operation, and the drive of the conveyance roller 2 are stopped, and the conveyance roller 1 is changed.
(Step 4] 6), the n+1th sheet is ejected to the inserted sheet on which no recording is performed.

At this point, copying based on the original is temporarily stopped and the operator waits for the operator to replace the original (step 4). When the operator replaces the original and turns on the start switch 14 again, the original is as described above. After n copies have been made and the sheets have been ejected, sheet 8 is ejected onto an insert sheet with no recording. Here, the start switch 1 is activated within the time set by the timer.
If 4 is not turned on, all the above operations are immediately stopped. If such operations are repeated for each document, an insert sheet Ks will be inserted each time the type of copy paper changes, and the copy paper in the same state will be obtained, making it easy to sort the copy paper afterwards. . Incidentally, if it is not necessary to identify the paper sheet as described above, in step 402, the insertion switch 1 is turned on.
5 without turning on the start switch 14, immediately proceed to step 418, specify the desired number of copies NIf), and then turn on the start switch 14.
Turn on and start shooting (Steps 418-421)
Due to the error, normal copying is performed without inserting the insert sheet KS, and the copying ends when the CPU 22 counts up the specified number of sheets N+' (step 422). Number of 8 pieces before cutting! If the start switch 14f is turned on without specifying i-%, only one copy sheet can be obtained (steps 423 and 424). In the above explanation, we have only described identification control for copy paper using one type of recording paper loaded in the other tray in a two-tray type copying machine, using one tray as an insertion paper supply tray. Even in a copying machine equipped with many recording paper supply trays, if the above control is performed after selecting the recording paper to be loaded in each tray, then these paper sheets can also be distributed. Of course, it becomes possible to identify the type of circulation. The present invention can also be applied to a copying machine that is equipped with an automatic document feed mechanism and is capable of continuously copying various types of copies every predetermined number of sheets. Different divisions can be made in one operation.

〔Effect of the invention〕

As explained above, according to the copying machine of the present invention, the inserted paper that is loaded into any recording paper supply tray during copying of the same type or different type of original can be ejected without recording every predetermined number of copies. By simply adding a simple and inexpensive control circuit without using a sorter or a dedicated paper tray, it is possible to easily sort multiple sheets of the same type of copy paper by several sheets and sort different types of copy paper by type. It produces an excellent effect.
