Abstract

PURPOSE:To extremely sharply record an additional image at a specific speed by allowing an additional image recording means to record an additional image on the rear part of a recording medium. CONSTITUTION:After paper is ejected from a fixing device 8 and its trailing edge passes by a fixing completion detecting switch 52, an ink ribbon motor is started up to make an additional data recording mechanism 9 operable. In this case, the backward end of the paper and an ink ribbon 67 lie between the periphery of a thermal head 34 and that of a platen roller 55. A step motor is intermittently driven step by step until it is driven by 80 steps. During this period, the head 34 sequentially records one line of additional data. In such a way, the step motor is stopped for each line, and the head 34 records additional data. Then, contents of additional data are clearly recorded.

<Prior Art> A recording device for recording additional information is usually placed downstream of a fixing device, and the additional information is recorded when the leading edge of the copied paper reaches the recording device. (Refer to Japanese Patent Laid-Open No. 61-53665).

<Problems to be Solved by the Invention> By the way, a recording device usually has a configuration that includes an ink sheet and a thermal head, or if it has a configuration that includes a thermal head, the recording speed of the thermal head is relatively slow, so the recording speed of the paper is Unless the conveyance speed is slowed down, additional information cannot be clearly recorded.

However, even when the leading edge of the paper reaches the thermal head, the latter half of the paper still remains in the fixing device.
If the conveyance speed of the paper is extremely reduced, there is a risk that the latter half of the paper may be deformed or scorched by the heat generated by the fixing device. Therefore, the conveyance speed of the paper cannot be made very slow, and conventional recording apparatuses have the disadvantage that it is difficult to record additional information clearly. This drawback is especially

<Embodiments> Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an illustrative diagram showing the overall configuration of a copying machine according to an embodiment of the present invention. This copying machine is equipped with a contact glass 2 for placing an original and a document holder 3 on the upper part of the main body 1 of the copying machine. A fixing device 8, an additional data recording mechanism 9, a punching mechanism 10 and a refeed path 11 are provided.

The optical system 4 illuminates and scans an original (not shown) set on the contact glass 2, and guides the reflected light to the image processing mechanism 5, as shown by the dotted chain line in the figure. be.

The image processing mechanism 5 is for reproducing an original image using an electrophotographic method. Specifically, after the surface of the photoreceptor drum 13 is uniformly charged by the charger 12, the surface of the photoreceptor drum 13 is exposed to light reflected from the original guided by the optical system 4, and an electrostatic latent image corresponding to the original image is formed. Form. The electrostatic latent image is developed into a toner image by the developing device 14, the toner image is transferred to the surface of the paper by the transfer charger 15, and the paper to which the toner image has been transferred is removed from the surface of the photoreceptor drum 13 by the separation charger 16. Peel off.

The paper feed path 6 is a mechanism for supplying paper for transferring a toner image to the photosensitive drum 13, and is a paper feed cassette 17, 18 or a stacking bypass 19 that is removably installed in a predetermined position of the copying machine 1. The paper is taken in one by one from the photoreceptor drum 13 by the registration rollers 20 at a constant timing linked to the image processing operation of the image processing mechanism 5.

The paper transport path 7 is for transporting the paper onto which the toner image peeled off from the photoreceptor drum 13 has been transferred to the fixing device 8 .

The fixing device 8 includes a fixing roller 21, and by pressurizing or heating the paper with the fixing roller 21,
It fixes the toner image transferred onto the paper.

The additional data recording mechanism 9 as additional image recording means is arranged downstream of the fixing device 8 with respect to the paper conveyance direction.
This is for recording additional data on paper to which a toner image has been fixed, ie, copied paper. The detailed configuration and operation of this recording mechanism will be described later.

The punching mechanism 10 is provided further downstream than the additional data recording mechanism 9 with respect to the sheet conveyance direction, and is capable of punching holes in the sheet discharged to the discharge tray 22.

The paper refeeding path 11 is provided with a switching pawl 23, and by switching the switching pawl 23, it is possible to switch whether the paper sent out from the fixing device 8 is guided to the additional data recording mechanism 9 or to the paper refeeding path 11. It looks like this. Paper refeed path 1
1 includes a paper reversing/feeding switching section 24, an intermediate tray 25, and a paper refeeding section 26. The paper reversing/feeding switching section 24 is for switching between reversing the paper for reverse side copying and feeding the paper as is for composite copying. When reversing the paper, the paper is once sent to the first path 28 by the switching pawl 27, and then the switching pawl 27 is switched, and the paper from the first path 28 is sent to the intermediate tray 25 via the two second paths. It will be done.

On the other hand, during composite copying, the paper guided to the first path 28 by the switching claw 27 is sent directly to the intermediate tray 25.

Of the above configurations, the image processing mechanism 5, paper feed path 6, paper transport path 7, fixing device 8, and paper refeed path 11 are driven by a main motor not shown in FIG. . On the other hand, paper is conveyed in the additional data recording mechanism 9 and the punching mechanism 10 by a step motor not shown in FIG.

As a result, the paper transport speed in the additional data recording mechanism 9 and the like can be changed with respect to the paper transport speed from the paper feed path 6 to the fixing device 8 and from the paper refeed path 11.

The copying machine main body 1 is also provided with an operation panel 30 on its top surface. The operation panel 30 is used to input various command signals and setting signals, display operation details, and the like.

A detachable handy scanner 31 is further connected to the copying machine main body 1. The handy scanner 31 is a device that can read any additional information including image data. The handy scanner 31 includes a line sensor with a width of, for example, 64 mm that can read data, and by manually scanning it, it can read data for 80 lines at a time, that is, (1 line - 64 mm) x (80 lines = It is capable of reading data in an area of 10 mm). This type of handy scanner 31 itself is commercially available and is a known component.

One of the features of this embodiment, which will be described in detail later, is that arbitrary image data can be read by the handy scanner 31 and the image data can be recorded by the additional data recording mechanism 9.

FIG. 2 is a block diagram showing the electrical configuration of the above-mentioned copying machine.

This copying machine is equipped with a CPU 32 as a control center, and the CPU 32 has an input/output interface 33.

As described above, the main motor 35 and the step motor 36 are for driving the image processing mechanism 5, the fixing device 8, and the conveyance system included in the copying machine.

Various drive mechanisms constituting the copying machine are further connected to the CPU 32 via an input/output interface 33, but since they are not particularly related to the features of this embodiment, the second
It is omitted in the figure.

The CPU 32 also has a font RO as a storage means.
M36 and RAM40 are connected. font R
OM39 is a read-only memory in which character data is stored in advance. As will be described later, when specific characters or numbers are recorded by the additional data recording mechanism 9 (see Figure 1), those specific characters or numbers are stored in this font ROM.
39 and stored in the buffer area 43 of the RAM 40.

The RAM 40 includes the buffer area 43, the first memory area 41, and the second memory area 42 described above. The first memory area 41 and the second memory area 42 are areas used for storing data etc. read by the handy scanner 31. The buffer area 43 is an area for temporarily storing data read by the handy scanner 31 or temporarily storing data read from the font ROM 39 and written by the thermal head 34.

Next, a specific example of the operation panel 30 is shown in FIGS. 3A and 3B. 3A and 3B show the operation panel 3
FIG. The actual operation panel 30 has a long and narrow planar shape, so in the figure,
The left half is shown in FIG. 3A, and the right half is shown in FIG. 3B. The operation panel 30 is equipped with various data setting keys, operation command keys, display lamps, and indicators necessary for operating this copying machine.

Among these, the operation keys unique to this embodiment are the mode selection key 44 and the display content selection key 45. Each time the mode selection key 44 is pressed, that is, each time a signal from the mode selection key 44 is applied to the CPU 32 (see FIG. 2), the operation mode of the copying machine is switched. The mode lamps 46 to 48 indicate which mode the operation mode is.
is expressed by That is, the scan mode, print mode, function mode, or normal mode is indicated depending on whether the scan mode lamp 46, print mode lamp 47, or function mode lamp 48 is lit, or whether any mode lamp is lit. .

When a desired mode is selected using the mode selection key 44, various displays are displayed for each mode on the liquid crystal multi-display 50, as shown in FIG.

To explain in detail with reference to FIG. 4, in the scan mode, the scan mode lamp 46 is turned on and the display content on the liquid crystal multi-display 50 becomes A1. In this state,
When the display content selection key 45 is pressed once, the display content is A.
2, and the data stored in the buffer area 43 of the RAM 40 (see FIG. 2) is displayed. Furthermore, when the display content selection key 45 is pressed once, the display content becomes the data content stored in the first memory area 41 of the RAM 40, as shown in A3, and the display content selection key 45 is further pressed.
When 5 is pressed once, the display contents are as shown in A4.
This is the data content stored in the second memory area 42 of the RAM 40. Furthermore, the display content selection key 45 is set to 1.
When pressed twice, the display contents return to A1. in this way,
In response to the display content selection key 45 being pressed, the display content of the liquid crystal multi-display 50 is cyclically switched.

In any display state, if the display content selection key 45 is continuously pressed for a certain period of time, for example, 3 seconds or more, the display content becomes as shown in A5, and the handy scanner 31 (see Figure 1) The light is turned on, allowing the handy scanner 31 to read data.

In the print mode, the print mode lamp 47 is turned on, and the display content on the liquid crystal multi-display 50 becomes one of B1 to B6. Also in this mode, the display contents are cyclically switched by pressing the display contents selection key 45. ``Circulation'', ``Reference'', ``Important'', and ``Urgent Circulation'' displayed on the LCD multi-display 50 in this mode.
Characters such as "Confidential" and "rcOPY prohibited" are in font R.
This is additional data read from the OM 39 and stored in the buffer area 43.

Note that the data recorded in the font ROM 39 in advance is
The data is not limited to the six types described above, and may be other types of data. Further, the number of data may be larger than that in this embodiment.

In the function mode, the function mode lamp 48 is lit and the liquid crystal multi-display 50 becomes C1 or C2. That is, date data is stored as additional data in the buffer area 431 and displayed. You can choose to display date data in Western calendar or era name. The display is switched cyclically in accordance with the operation of the display content selection key 45, as described above.

In the normal mode, none of the three mode lamps 46 to 48 are lit, and the display contents on the liquid crystal multi-display 50 are as follows.
Become Dl.

Now, returning to FIG. 3, the other operation keys and display portions on the operation panel 30 are not directly related to the configuration that characterizes this embodiment, so their explanations will be omitted here.

Next, the display contents of the liquid crystal multi-display 50 become as shown in FIG. 4 A5, and the handy scanner 31 is turned on.
The control operation when it becomes possible to read data will be explained.

FIG. 5 is a flowchart showing the control operation of the CPU 32 (see FIG. 2) in the scanner input mode in which data can be read by the handy scanner 31.

To explain with reference to FIGS. 2 and 5, the CPU 32
In the scan mode (step S1), when it is determined that the display content selection key 45 has been turned on for a predetermined period of time, for example, 3 seconds or more (step S2), the handy scanner 31 is turned on (step S3), and the handy scanner 31 is turned on (step S3). 31 to read data. Then, set a 10 second timer on the program (step S4)
.

When the data is read by the handy scanner 31, it is stored in the buffer area 43 of the RAM 40 (step S5), and it is determined whether the data in the first row has been correctly input (step S6).

1 during the 10 seconds until the 10 second timer times out.
If the data in the row is not input normally (step 511), the buffer area 43 is cleared (step 512), the handy scanner 31 is turned off (step 514), and the scanner input mode is ended.

If the data on the first line is input correctly, CPU3
2 resets the 10 second timer (step S7), and when the data from the 2nd to 80th lines are read by the handy scanner 31, it is stored in the buffer area 43 (step S8).

During this time, the CPU 32 determines whether the 10-second timer has timed out (step 513), and if the data up to the 800th line is not accurately input within 10 seconds, clears the buffer area 43 (step 512). ), turns off the handy scanner 31 (step 514), and ends the scanner input mode.

If the input of data up to the 800th line is completed accurately within 10 seconds after inputting the data on the 1st line (step S9),
The CPU 32 displays the data stored in the buffer area 43 on the liquid crystal multi-display 50 (step 510).
, turn off the handy scanner 31 (step 514).
), exit scanner mode.

In this embodiment, when the display content selection key 45 is turned on continuously for a predetermined period of time (3 seconds in this embodiment) or more, the scanner enters the manual mode. If no data is read for more than 2 seconds, the scanner manual mode is canceled. The reason for this is that in this embodiment, a single CPU3
2 controls both the entire copying machine and the data reading by the handy scanner 31.

Therefore, when reading data with the handy scanner 31, the copying machine main body 1 cannot be controlled.

Therefore, in addition to preventing the scanner input mode from easily entering the scanner input mode, the scanner input mode is canceled after a certain period of time even if the scanner input mode is entered, and the original copying machine control can be performed. It is.

FIG. 6 shows that when data read by the handy scanner 31 is stored in the buffer area 43, the read data is
FIG. 3 is an illustrative view showing how the direction is changed by 80 degrees.

That is, step S in the flowchart of FIG.
During the data reading processing in step S5 and step S8, 180 degree direction conversion of the read data is performed as described below.

As mentioned above, the handy scanner 31 is equipped with a line sensor, and one line consists of 64 elements each having 512 bits and 8 b i . In other words, the line sensor of the handy scanner 31 has a configuration in which 64 reading elements are arranged in a line. The data read by this line sensor is stored in the buffer area 43 in the order of first-in and last-out for each reading element, as shown in FIG. 6, and the order of storage is changed by 180 degrees.

In this way, if the direction is changed by 180 degrees when storing read data, the printing direction can be reversed by 180 degrees when printing the contents of the buffer area 43. When data read by the handy scanner 31 is stored in the buffer area 43 in the usual manner, when the data is printed, it is printed upside down. Therefore, in this embodiment, when the data read by the handy scanner 31 is stored, the direction of the data is changed by 180 degrees.

FIG. 7A is a diagram showing the magnitude relationship between the recording capacity of the buffer area 43 and the display capacity of the LCD multi-display 50, and FIG. FIG. 6 is a diagram illustrating the procedure for reading data when displaying the data.

That is, step S10 of the flowchart shown in FIG.
In this case, when the data stored in the buffer area 43 is displayed on the liquid crystal multi-display device 50, the following data compression processing is performed.

As shown in FIG. 7A, the buffer area 43 can store at least 80 lines of data with 512 bits per line, while the liquid crystal multi-display 50
It has a display capacity of only 20 lines with 128 bits per line.

Therefore, in this embodiment, as shown in FIG. 7B, among 64 sets of data arranged in units of 8 bits in one line, only the 7th bit and 3rd bit of each set are read out. In addition to compressing data,
In the row direction, the 1st row, 5th row, 9th row, 13th row, etc.
・The row data is read out intermittently according to the arithmetic progression of 4 rows to compress the data.

As a result, the buffer area 4 has a relatively large storage capacity.
3 can be similarly reduced and displayed on the liquid crystal multi-display device 50, which has a relatively small display capacity.

In this embodiment, the display is reduced to one-fourth as described above, but if the storage capacity of the buffer area 43 and the display capacity of the liquid crystal multi-display device 50 are equal, there is no need to reduce the display size. If the storage capacity and display capacity are in a different ratio, the stored data may be reduced accordingly.

Next, the configuration and operation for recording the additional data stored in the buffer area 43 onto a sheet of paper by the additional data recording mechanism 9 including the thermal head 34 will be described.

8A and 8B are illustrative cross-sectional views showing more detailed configuration examples of the additional data recording mechanism 9 in this embodiment, and FIG. 8A shows when the additional data recording mechanism 9 is in the inactive state. FIG. 8B shows the additional data recording mechanism 9 in the active state.

In FIGS. 8A and 8B, a fixing discharge roller 51 is arranged at the exit of the fixing device 8, and a fixing completion detection switch 52 is provided on the downstream side with respect to the paper conveyance direction. When the leading edge of the paper is ejected from the fixing and ejecting roller 51, the detection switch 52 falls from the state shown by the solid line to the state shown by the dashed line and turns on, and the trailing edge of the paper passes over the detection switch 52. The switch returns to the solid line state and turns off the moment it is finished. Therefore, by detecting the switching edge of the fixing detection switch 52 from on to off, the trailing edge of the sheet can be detected.

The paper discharged from the fixing discharge roller 51 is conveyed downstream in the conveyance direction by a conveyance roller 53. On the downstream side of the conveyance roller 53, a switching pawl 23 is provided adjacent to the conveyance roller 53. As already explained, the switching claw 23 guides the paper toward the ejection roller 54 side in the solid line state, and guides the paper toward the paper refeeding path 11 side in the state shown by the - dotted chain line.

An additional data recording mechanism 9 and a punching mechanism 10 are provided in this order along the path through which the paper guided to the discharge roller 54 by the switching claw 23 passes.

The additional data recording mechanism 9 includes a platen roller 55 arranged on the paper conveyance path and a thermal head 34 that can be moved up and down. The thermal head 34 is the 8th A
As shown in the figure, it is movable between a state in which it is raised from the platen roller 55 and a descending state in which its headline is in contact with the circumferential surface of the platen roller 55, as shown in FIG. 8B.

More specifically, a member 58 is provided which is rotatable about a support shaft 57, and the thermal head 34 is attached to this attachment member 58. The mounting member 58 is usually a leaf spring 6 to the casing 66 of the additional data recording mechanism 9.
1 and the return spring 59 apply a clockwise moment in the figure, and as a result, the thermal head 34 waits at a position elevated from the platen roller 55. The mounting member 58 also includes a cam 6.
0 is engaged. The cam 6o is adapted to be reversed 180 degrees by a head elevating solenoid (not shown), and when reversed, rotates the mounting member 58 counterclockwise as shown in FIG. 8B. As a result, the thermal head 34 is lowered against the reaction force of the leaf spring 61 that contacts the casing 66, and is brought into contact with the peripheral surface of the platen roller 55.

Note that when the thermal head 34 comes into contact with the peripheral surface of the platen roller 55, the contact force is kept constant by the action of the leaf spring 61.

The additional data recording mechanism 9 is further equipped with a pair of ribbon pulleys 62 and 63, and these ribbon pulleys 6
2. An ink ribbon 67 was passed between the two.
The ink ribbon 67 covers the headline line of the thermal head 34. Therefore, when the thermal head 34 is brought into contact with the peripheral surface of the platen roller 55 as shown in FIG. 8B, the ink ribbon 67 is brought into contact with the head line of the thermal head 34, and when the thermal head 34 is driven, , the ink on the ink ribbon 67 is transferred to the platen roller 55 side, that is, to the paper side.

Note that the ink ribbon 67 is preferably colored in a color different from the color in which the original image is recorded, for example, when the original image is recorded in black, the ink ribbon 67 is colored red. Of course, the ink ribbon 67 of the same color as the original image may be used.

In this embodiment, a solenoid for raising and lowering the head (not shown)
Although the cam 60 is rotated by 180 degrees and the thermal head 34 is thereby raised and lowered, the thermal head 34 may be raised and lowered directly by a solenoid.

Further, the cam 60 may be rotated by a motor.

Furthermore, the thermal head 34 is fixed on the paper conveyance path,
The platen roller 55 may be moved up and down.

FIG. 9 is a timing chart for explaining the control operation of the additional data recording mechanism 9. Next, the control operation of the additional data recording mechanism 9 will be explained with reference to FIGS. 8A, 8B, and 9.

The conveyance roller 53, the discharge roller 54, and the platen roller 55 are driven by the step motor 36 (see FIG. 2), as described above. As a result, unlike the fixing discharge roller 51 and the like of the fixing device 8 which are driven by the main motor 35, the rotation speed thereof can be changed.

When the thermal head 34 is not in the lowered active state as shown in FIG. 8B, the paper ejected from the fixing device 8 must be conveyed in the ejection direction without being loosened or pulled. . Therefore, when the additional data recording mechanism 9 is in the disabled state, the conveyance roller 53 and the discharge roller 54
The platen roller 55 is rotated by the step motor 36 at, for example, 300 mm/sec. This speed is equal to the speed of the paper conveyance path 7 and the fixing device 8 driven by the main motor 35.

When the paper is ejected from the fixing device 8 and the trailing edge of the paper finishes passing the fixing completion detection switch 52, the detection switch 5
2 switches from on to off. The step motor 36 is stopped after a predetermined time has elapsed since the off-edge detection of the detection switch 52.

When the step motor 36 is stopped, the trailing edge of the paper is placed at a predetermined position, for example, at a position 10 on the upstream side of the platen roller 55.
It is located at mm. 100 after the step motor 36 stops
After m5ec, the head elevating solenoid 37 is turned on, and the ink ribbon motor 38 (see FIG. 2) is activated. As a result, the additional data recording mechanism 9 becomes active.

In this case, the vicinity of the rear end of the paper and the ink ribbon 67 are interposed between the thermal head 34 and the peripheral surface of the platen roller 55.

After the head elevating solenoid 37 is turned on, for example, 3
After 00m5ec, the step motor 36 is driven intermittently one step at a time, and is driven for 80 steps. Each time the step motor 36 is stopped, one line of additional data is sequentially recorded by the thermal head 34. In this way, when the step motor 36 is stopped for each line and the additional data is recorded by the thermal head 34, the contents of the additional data can be clearly recorded.

Additionally, since the additional data is recorded on the trailing edge of the copied paper, no part of the paper remains in the fixing device 8, so there is a risk that part of the paper may become deformed or scorched. do not have.

After the step motor 36 is operated 80 steps, -
Once stopped, the head lifting solenoid 37 is turned off, and the thermal head 34 is lifted by the reaction force of the leaf spring 61 and the attractive force of the return spring 59. Since the ink ribbon motor 38 continues to rotate for, for example, 200 m5ec during and after the thermal head 34 is raised, the ink ribbon 67 that was fed out during printing is smoothly wound up, and the ink ribbon 67 does not stick to the paper. There will be no slack or unnecessary slack.

After stopping for 200 rrr seconds, the step motor 36 is rotated at a constant speed for a certain period of time. As a result, the paper on which the additional data has been recorded on the trailing edge is ejected from the ejection roller 54 to the ejection tray 22 (see FIG. 1).

Thereafter, in the case of continuous copying, the step motor 36 returns to the same speed as the original 300 mm/sec main motor 35, and in the case of single-shot copying, it is stopped.

In this embodiment, a fixing completion detection switch 52 is provided at the discharge section of the fixing device 8, and this detection switch 52
The trailing edge of the paper is detected based on the edge that is turned off from the edge, and the recording position of the additional data is controlled to be at the desired position. The recording position of the additional data may be determined by detecting the trailing edge position of the paper based on a registration switch provided at the position of the roller 20 (see FIG. 1).

Also, a discharge confirmation switch 65 is connected to the discharge roller 54.
(See Figure 8A), if the paper size is known, the leading edge of the paper is detected by this ejection confirmation switch 65, and then the recording position of additional data is determined based on it. You can do it like this.

Furthermore, since the distance from the registration rollers 20 to the additional data recording mechanism 9 is constant, if the paper size is known, the additional data recording timing is controlled based on the paper feeding timing by the registration rollers, and the Additional data can be recorded at desired locations. In other words, even if the paper is not detected by a specific paper detection switch, the position of the paper can be calculated, and thereby the recording position of additional data can be controlled.

The above explanation has mainly focused on the case where one-sided normal copying is performed, but in the case of double-sided copying or composite copying, just before the copied paper on which double-sided copying or composite copying is completed is ejected to the output tray 22. Additional data will be recorded.

FIG. 10 shows the correspondence between the state in which the original is set on the contact glass 2 and the copied paper on which additional data is recorded. Additional data is generally preferably recorded at the top or bottom of the document content. In this example,
If you want to record additional data at the top edge of the original content, set the original so that the trailing edge is aligned with the reference line of the contact glass 2, and then copy, as shown in Figure 10 (A). Additional data is recorded at the upper end of the original image on the paper. Furthermore, as is clear from Fig. 10 (A),
The vertical direction of the additional data matches the vertical direction of the manuscript. This is because, as explained above, when the data read by the handy scanner 31 is stored in the buffer area 43, its direction is reversed by 180 degrees.

On the other hand, if additional data is to be recorded on the bottom edge of the copied paper, the original may be set so that the leading edge of the original is aligned with the reference line of the contact glass 2, and then the original is copied. In such a case, when storing the data read by the handy scanner 31 in the buffer area 43, the direction should not be reversed. Then, the vertical direction of the additional data becomes the same as the vertical direction of the original image.

Note that not only the data read by the handy scanner 31 is stored in the buffer area 43, but also the data read by the handy scanner 31 is stored in the font ROM.
When reading the data of No. 39 and storing it in the buffer area 43, if necessary, the order of storing the data may be reversed.

Also, when storing data in the buffer area 43,
For example, a changeover switch (not shown) may be provided to enable switching whether to store the image inverted or to store it without inversion. This changeover switch is preferably a switch that also serves as a changeover switch for switching between recording additional data on the top edge of the paper and recording additional data on the bottom edge of the paper.

Although the above embodiments have been explained using a copying machine as an example, it should be noted that the present invention can be similarly applied to image recording devices such as printers and facsimile machines.

<Effects of the Invention> Since the present invention is configured as described above, when an additional image is recorded together with a document image, the additional image can be recorded at a suitable position in a recording medium.

Particularly, when an additional image is recorded on the rear end of the recording medium, the recording medium will not be discolored by the heat of the fixing device included in the original image recording means.

Further, the additional image recording means can be placed near the original image recording means, and the overall size of the apparatus is not increased.

Furthermore, since the additional image can be recorded at a specific speed, it can be recorded extremely clearly.

Furthermore, if the additional image recording means is separated from the recording medium after recording the additional image, the recording medium can be conveyed relatively quickly, and in this case, the recording medium will not get dirty due to the ink ribbon etc. adhering to the recording medium. .
