Abstract

PURPOSE:To facilitate a bending operation by driving intermittently a half- cutting mechanism based on pitch size data and the number of perforations, and driving a cutting mechanism for a rolled form paper based on length data. CONSTITUTION:Where pitch size data is set at an A4 size length, for example, when printing on a paper having a length equal to two times the A4 size length is to be performed, there is the condition of (printing length data) = (pitch size data) X 2. In this case, 1 is set on a half-cutting counter HC, and data corresponding to a feeding time for a rolled form paper 29 for A4 size sheets is set on an A timer TA and a B timer TB. With the paper 29 fed to be detected by a paper sensor 28, a half-cutter magnet 25 is thereafter operated when the paper 29 is fed for the counting time set on the A timer TA after the detection of the paper 29 by the sensor 28, whereby the paper 29 is provided with a perforation just at an A4 size position. When the paper 29 is then fed further for the counting time set on the B timer TB, a cutter motor 26 is operated to cut the paper 29.

This cut roll paper is supplied as transfer paper to a transfer section of an electrophotographic apparatus by a feed roller 8.

The length of the roll paper to be cut can be arbitrarily changed depending on the length of the electronic photo set externally.

[Problems to be Solved by the Invention] As described above, in the conventional roll paper supply device, when the length of an electronic photograph is set, paper that is simply cut according to the length is supplied. If you create an electronic photo and file it, if you create an electronic photo several times the length of A4 size, you will have to fold it to A4 size to file it, but the electronic photo has There were no creases at all, so there was a problem in that the bending work was troublesome.

SUMMARY OF THE INVENTION Therefore, the present invention aims to provide a roll paper feeding device that can feed long sheets of paper with perforations attached to the folded portions, thereby facilitating folding operations such as filing. It is something to do.

[Means for Solving the Problems] The present invention provides a roll paper supply device that feeds a long roll paper, cuts the roll paper into an appropriate length, and supplies the roll paper as transfer or printing paper. A roll paper cutting mechanism that cuts, a half-cut mechanism that creates perforations in the roll paper, a length data memory that stores length data of the supplied paper, and a pitch size that stores pitch size data that specifies the perforation position. a memory, a number calculation means for calculating the number of perforations to be made on the roll paper from the length data and pitch size data of the length data memory, a sensor for detecting the roll paper to be sent out, and a sensor for detecting the roll paper by this sensor. In response, a half-cut control means intermittently drives the half-cut mechanism based on the pitch size data in the pitch size memory and the number of perforations calculated by the number calculation means; A cut control means for driving a roll paper cutting mechanism is provided.

[Function] In the present invention having such a configuration, when the roll paper is sent out, it is first detected by the sensor. When the sensor detects this, the half-cut mechanism is intermittently driven based on the pitch size data in the pitch size memory and the number of perforations calculated by the number calculation means, and perforations are made at equal intervals on the roll paper. . Finally, the roll paper cutting mechanism is operated based on the length data in the length data memory to cut and supply the roll paper.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. In this embodiment, the present invention is applied to a dry electrophotographic apparatus.

FIG. 1 is a block diagram, and numeral 11 is a main body control MPU (microprocessor) of the electrophotographic apparatus. This MPU 11 is designed to control the RAM 12, ROM 13, various main unit drivers 14, and I/F (interface>15.16).A host computer 17, which is a host device, is connected to the 1/F 15.
A roll paper supply device 18 of the present invention is connected to the I/F 16.

The main body various drivers 14 include an exposure section, a photoreceptor, a development section, a transfer section, a fixing section, which constitute the driving section of the electrophotographic apparatus.
A cleaning section, a static eliminator, a paper transport mechanism, an operation section, etc. are connected.

The main body control MPU II receives data from the host computer 17, converts the received data into print data, etc., and stores it in the RAM 12. Furthermore, print length data, pitch size data, etc. are generated based on setting operations on the operating section, and transmitted to the roll paper supply device 18 via the 1/F 16.

The roll paper supply device 18 is provided with a roll paper feeder control MPU 21, and the 1/F
16, ROM22, RAM23 and various drivers 24
are connected.

The various drivers 24 include a half cutter magnet 25, a cutter motor 26, and a feed motor 27.
, paper sensor 28 is connected.

The configuration of the roll paper supply device 18 is shown in FIG. In other words, a long rolled paper 2
9 is connected to the paper sensor 2 midway by a feed roller 3o rotationally driven by the feed j motor 27.
8 to the roll paper cutting mechanism 31 side.

The roll paper cutting mechanism 31 includes the cutter motor 2.
A cutter blade 32 rotated by the cutter 6 is provided, and the roll paper 29 is cut by the rotation of this blade 32.

The roll paper 29 that has passed through the roll paper cut mechanism 31 is further sent to a feed roller 34 via a half cut mechanism 33. This feed roller 34 is adapted to feed the roll paper 29 to the transfer section of the main body of the apparatus.

The half-cut mechanism 33 is for making perforations on the roll paper 29, and as shown in FIG.
a fixing member 38 having a plurality of holes 37 for receiving each month 35 of the
The movable member 36 is moved up and down by the half cutter magnet 25.

As shown in FIG. 4, the RAM 23 includes a print length memory PL as a length data memory that stores print length data that determines the length of the paper, and pitch size data that specifies the position of perforations to be made on the roll paper. A pitch size memory PS10 that stores the number of perforations to be made on roll paper, a half-cut counter HC, and an A timer TA that counts the transportation time of the roll paper, which determines the perforation position determined based on the pitch size data. , a B timer TB, etc. that counts the time from when the final perforation is made until the roll paper 29 is cut based on print length data, pitch size data, and the number of perforations.

The roll paper feeder control MPU21 is a ROM.
Based on the program data No. 22, the roll paper supply control shown in FIG. 5 is performed.

First, initial processing Sl is performed. This initial processing sets various ports as shown in FIG. This initializes the various drivers 24 and makes 1/F16 ready.

Next, the ROM 22 and RAM 23 are checked. Next, clear the print length memory PL, clear the pitch size memory PS, and clear the A timer TA and B timer TB.
is cleared, and the half-cut counter HC is also cleared to end this initial processing.

After the initial processing S1 is completed, data storage processing S2 is subsequently performed. As shown in FIG. 7, this checks whether the data received via the I/F 16 is a print length code indicating the total length of the paper.

If the print length code is correct, the print length data following it is stored in the print length memory PL. Next, it is checked whether the received data is a pitch size code indicating the pitch of perforations. If the pitch size code is correct, the pitch size data following it is stored in the pitch size memory PS. However, if the code received at this time is incorrect, it is determined as a code error and is transmitted to the main body control MPU II. Then, it ignores the data received so far and waits again to receive the code.

After the print length data and pitch size data are stored in the memories PL and PS, respectively, the A timer TA,
Set B timer TB and half cut counter HC. That is, the A-timer TA calculates the time it takes for the roll paper to be conveyed by the pitch size from the pitch size data, and sets the time as a count number. Further, the number of perforations calculated from print length data and pitch size data is set in a half-cut counter HC.

In addition, the B counter TB is set as a count number, which is the length of time the roll paper is conveyed from the last perforation calculated from the print length data, pitch size data, and the number of perforations until the roll paper is cut. Become. Therefore, print length data - pitch size data x number of perforations + final size data, that is, feed motor 2
08 hours of 7 - ON time of feed motor 27 by A timer TA x count of half cut counter HC tens of minutes 08 of feed motor 27 by B timer TB
A time relationship will be established.

When the required data is set in this way, this data storage process is ended.

Next, when a print start code is received via the I/F 16, the feed motor 27 is started to transport the roll paper 29.

In this state, when the paper sensor 28 detects the roll paper 29 and turns ON, half-cut control S3 is performed. This is the 8th
As shown in the figure, first, it is checked whether or not the A timer TA counts up.

Then, the roll paper 29 is conveyed until the count up, and when the A timer TA counts up, the roll paper 29
It is determined that the feed motor 27 is at the sewing machine opening position, the feed motor 27 is sped up a little to slacken it, the feed motor 27 is stopped, and the half cutter magnet 25 is turned on. Next, half cut counter H
Decrement C by -1.

Then, the feed motor 27 is rotated at a steady speed to transport the roll paper 29 again.

The above control is repeated until the half-cut counter HC reaches "0", and when the counter HC reaches "0", this half-cut control is ended and then paper cut control S4 is performed.

This paper cut control S4 starts a B timer TB as shown in FIG. And this B timer TB
It is checked whether the count is up or not, and when the count is up, the feed motor 27 is sped up a little to slacken it, and then the cutter motor 26 is rotated once to rotate the blade 32 and cut the roll paper 29. Next, print length memory PL, pitch size memory PS,
A.

The B timers TA and TB and the half cut counter HC are cleared to end this paper cut control.

When the paper cut control S4 is completed, the routine returns to the data storage process S2.

In this embodiment with such a configuration, for example, if the pitch size data is set to the length of A4 size,
When printing (transferring) onto paper that is twice the length of the paper, print length data - pitch size data X2, half cut counter HC is set to 1, and A4 size is set to A timer TA and B timer TB. Data corresponding to the transport time of the roll paper 29 is set.

When the roll paper 29 is conveyed and the paper sensor 28 detects it, the roll paper 29 is then transferred to the A timer TA.
After being conveyed for a count time of , the half cutter magnet 25 is operated to form a perforation exactly at the A4 size position. After that, when the roll paper 29 is further conveyed for the time counted by the B timer TB, the cutter motor 26
is operated and the roll paper 29 is cut.

Although the length of the paper supplied to the transfer section of the main body of the electrophotographic apparatus is twice that of A4 size, a perforation is formed exactly in the middle of the paper.

Therefore, the paper finally obtained by transferring the toner image onto this paper in the transfer section can be easily folded into two along the perforations. Moreover, since the bending position is determined by the perforations, the bending position is also certain.

Also, printing on paper that is four times the length of A4 size (
When performing transfer), print length data - pitch size data x 4, and half cut counter HC has 3.
is set, and data corresponding to the transport time of the A4 size roll paper 29 is set in the A timer TA and B timer TB, respectively.

When the roll paper 29 is conveyed and the paper sensor 28 detects it, the roll paper 29 is then transferred to the A timer TA.
After being conveyed for a count time of , the half cutter magnet 25 is operated to form a perforation exactly at the A4 size position.

This operation is repeated two more times, and the roll paper 29 is perforated at three locations in total. When the third perforation is made, the roll paper 29 is further conveyed for the time counted by the B timer TB, and then the cutter motor 26 is operated to cut the roll paper 29.

However, although the length of the paper supplied to the transfer section of the main body of the electrophotographic apparatus is four times that of A4 size, three
Perforations will be added at certain points.

Therefore, the sheet finally obtained by transferring the toner image onto this sheet at the transfer section can be easily folded into four pieces along the perforations. Moreover, since the bending position is determined by the perforations, the bending position is also certain.

Since perforations are provided at equal intervals on relatively long sheets of paper, the work of folding the sheets for filing becomes easy. Moreover, the bending position at that time is also certain.

In the above embodiment, the present invention is applied to a dry type electrophotographic apparatus, but the present invention is not necessarily limited to this, and the present invention can also be applied to a paper supply device of a printer.

[Effects of the Invention] As described in detail above, according to the present invention, long sheets can be supplied with perforations formed at the portions that will become folds. It is possible to provide a roll paper supply device that is easy to work with.
