Description

[Detailed description of the invention] [! 1. Field of the Invention The present invention relates to a document conveyance device, and more particularly, to a mechanism for imprinting additional information on a document in association with the document conveyance device provided in a copying machine.

1 When copying a large number of manuscripts using a copying machine, it is often necessary to add common information to each manuscript, such as the date or questions and answers from the publisher. In response to this demand, various devices and mechanisms have been proposed in the past that are configured to imprint this type of additional information along with the document.

One of the known techniques is the technique disclosed in Japanese Patent Publication No. 60-21368 entitled "Sub-Information Impression Wi Structure for Image Forming Apparatus". This technology includes: a document conveying means for conveying a document to an exposure position of an image forming apparatus; a belt-like member provided at the exposure position; a holding means for holding a member on which information is written on the belt-like member; A subsidiary information imprinting mechanism for an image forming apparatus, comprising a moving means for driving the belt-like member in synchronization with a document conveyance means, and configured to appropriately advance the subsidiary information writing member to an exposure position. be.

By the way, the technique disclosed in the above-mentioned publication is applicable only to an image forming apparatus that forms an image on a photoreceptor drum, for example, which operates in synchronization with the transfer of an original. This method cannot be applied to an image forming apparatus in which the image is placed on a platen glass and exposed by the movement of a scanner. Furthermore, the above technology is an imprinting mechanism that is based on the premise that the image forming apparatus main body and the document supply/conveyance section are integrated, and the mechanism itself is a simple 8! Even if it is a structure, the mechanical or electrical control system must be incorporated into the main body of the image forming apparatus, and therefore, it is inevitable that the structure to be added will be complicated in relation to the main body of the image forming apparatus. Furthermore, this technique is constructed on the premise that additional information is to be imprinted, and it has been pointed out that there is a problem in that it is not easy to select whether to imprint or not to imprint.

Techniques for Solving Problems The present invention is based on a new idea despite the background of the above technology, and its main purpose is to improve the scanner 1.
An object of the present invention is to provide a new mechanism for easily imprinting additional information (sub-information) in an image forming apparatus of a type that exposes a document to light by moving the image forming apparatus, particularly in an existing copying machine of this type.

Another object of the present invention is to construct a mechanism for imprinting additional information independent of the main body of the copying machine, and to make it possible to select the imprinting method extremely easily. It also provides 1.

In order to achieve the above object, the present invention focuses on an automatic document feeder that is generally installed as an option in a document scanning type copying machine, and in this device, a fed document is transported to an exposure position of the copying machine. The conveyor belt is provided with a holding section for holding a sheet-like object displaying additional information, and the holding section is moved so that the holding section and the original document are aligned in parallel at the exposure position, and the original document is fed. The basic feature is that a control means is provided to drive the conveyor belt in synchronization with the movement, and the additional information can be imprinted along with the document.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be specifically described with reference to embodiments shown in the accompanying drawings.

FIG. 1 is a schematic perspective view of a copying machine according to an embodiment. In the figure, (1) is a main body of a copying machine, which is provided with a document table glass (3) for supporting a document (2) on its upper surface.

Inside the copying machine body (1), there is a constant F (original m(2)
This scanner scans the original ff1(2) from right to left in the figure. (4) is a production panel section where paper selection, number of copies, copy magnification, and copy density can be set.

On the other hand, (ioo) is an original document transport device (hereinafter referred to as ADF) installed on the top surface of the copying machine main body (1).
It is. This ADF (100) has a document tray (

The original fed from 2) is automatically conveyed to a predetermined location on the original platen glass (3) and set there, and when the copying operation is completed, the original platen transfers the original (2) on the glass platen (3). Original transport unit (103) that outputs to the output tray (104)
(hereinafter referred to as the DF section). And this DF
As shown in the figure, the section (103) is rotatably mounted on a hinge or the like with respect to the main body (1), and can be handled in the same manner as a normal document cover. That is, when the ADF is not used, the user opens the DF section (103), manually sets the original on the document table glass (3), closes the DF section (103), and starts the copying operation.

On the other hand, in ADF mode, the DF section (103)

) is inserted along the arrow.

FIG. 2 shows a mode selection section provided on the top surface of the DF section (103).

The key (50) is used to select whether or not to include additional information, that is, a memo.
0), the LED (50a) as the mode display
turns on or off. When LED (50a) lights up, it indicates that ADF (100) is in mode Y including 4 memos.

On the other hand, the key (51) is used to select an operation mode related to the operation of the copying machine main body (1), and when this operation mode selection key (51) is pressed, one of the keys lights up. LED (51a) as a display section.

(51b) and (51e) are lit cyclically. This L
Is the operation mode of the copying machine including A D F (100) set to auto paper selection, auto magnification selection, or manual mode by the lighting of ED (51a), (51b,), or (51c)? is shown. Here, the automatic paper selection mode means A D F (100
) Automatic magnification selection mode refers to a mode that automatically selects suitable paper from among the copy sheets loaded in multiple stages, based on the original size detected by the scanner and the copy magnification set by the operation panel section (4). means A D F (100
) is a mode in which an appropriate copying magnification is automatically selected based on the original size detected in the operation panel section (4) and the copy paper size selected on the operation panel section (4). In manual mode, the paper size is selected and set by the operator.

This mode operates the copying machine depending on the copying magnification. Of course, even in this mode, originals can be automatically set using the original functions of the ADF (100).

Note that for the first two modes, the ADF (100) is equipped with a sensor to detect the document size.
As shown in Fig. 1, two sensors (51f) and (51w) are installed on the lower surface of the DF section (103) on the side adjacent to section A.
is installed. The sensor (5H) detects the length of the original document based on the passage time of the transported original document.

On the other hand, the sensor (51w) detects the width of the passing document. These two sensors identify the size and orientation of the document. In addition, if it is standard paper such as A4 or B5,
Although the document length sensor (51f) alone is sufficient, since non-standard paper or paper with different width sizes even if the length is within the standard value is also used, a document width sensor (51u+) is also installed.

Next, an outline of the operation when imprinting a memo will be explained mainly with reference to FIGS. 4 and 5.

When L E D (50a) is off (fp12
), press the memo 4 included selection key (50) once, L
E D (50a) lights up and the memo 4 included mode is entered. The conveyor belt (33) moves and the memo setting section (34)
However, as shown in Fig. 1, there is a position (P) on the side facing the document platen glass (3) where the memo slip can be inserted (this position (P) on the front edge of the DF section (103)). (There is a gap large enough for a hand or finger to fit in.) Then, lift up the DF section (103) and open it, and as shown in FIG.
) is inserted or set. Then, the DF section (103) is closed. Next, set the original on the original tray (101) by adjusting the original edge guide (11), and place the original on the A part (102).
) on the ADF side print key (21
)Press.

Then, as shown in Figure 5, the transport bell (33) rotates in the direction of the arrow, and at a certain timing the document feed roller (
22) and a pair of document transport rollers (23) rotate. Then, when the rear end of the memo set section (34) reaches the right edge of the document table (3), the leading edge of the document reaches the conveyor belt (33).
The original (2) moves on the original platen glass (3).

Figure 4 shows the original plate plus (3) from the bottom in Figure 5.
The memo setting section (34) and the document (2) are stopped at the position shown in FIG. 4. That is, the memo setting section (34) is positioned such that the rear end of the document (2) contacts the document reference position of the document table (3) from the leading edge of the document (2) in the document transport direction. In this state, exposure is performed by the scanner, so the memo set section (34) is placed together with the document (2).
The piece of paper (39) set in is to be copied.

Of course, the memo paper (39) is within the depth of field of copying with respect to the imaging system of the scanner, and a clear copy image similar to the original image is formed.

After the copying operation is completed, the transport bell) (33) and the ejection port -
The R pair (41) rotates, and first the original (2) on the original platen glass (3) is ejected, and then the positional relationship between the leading edge of the next original and the memo set Y section (34) is shown in Figure 4. At the timing of the relationship shown, the document feed roller (22).

Two pairs of document transport rows (23) are rotated. Thereafter, by repeating this process, the contents of the memo set section (34) are always copied along with the original image at the end corners of the sheet in the longitudinal direction.

During the above operation, if the automatic magnification selection mode is selected using the operation mode selection key (51), the magnification will be automatically changed so that the copy magnification = selected paper length / (original length + memo set length). Ru. Note that the memo set section refers to the length of the memo set section (34) in the document conveyance direction. In addition to changing the magnification, you can also copy at the same size as (length of original minus memo set length) + (memo set length) = (standard paper length). Yo··. In this case, the conveyance of the document (2) is controlled so that the rear end of the document (2) protrudes from the right edge of the document table glass (3) by the length of the memo set section. Setting the original in this manner does not pose any particular problem since there is usually a considerable margin at the top or bottom of the original.

When the A D F (100) is in the memo 4 included mode, if you press the memo 4 included selection key (50) in Figure 2, the L E D (50a) will disappear and the memo 4 included mode will be canceled. . When the original N (2) is fixed at the exposure position, the memo set section (34) is placed at a position that is not exposed to the scanner's exposure, for example, when the original platen is at the rear (3).
The drive of the conveyor belt (33) is controlled so that the conveyor belt (33) is located at the opposite side to the side facing the conveyor belt (33).

A sensor (35s) monitors the running of the conveyor bell (33) in order to control the drive of the conveyor bell (33) so as to position the memo set part (34) at a specific position with respect to the document table glass (3). is provided. Sensor (35

In step (A5), the above steps (A3) and (A4
) The count value of the software timer used in ) is subtracted by 1, that is, the count value is counted down.

In step (80), it is determined whether the internal timer set in step (A1) has ended. When the process is finished, that is, a certain period of time has elapsed, the process returns to step (A1) and steps (A1) to (A6) are repeated.

Although related to the timer in step (A5), the time value of the timer used during this loop is determined based on how many times this loop is counted.

In FIG. 8 showing the details of the mode display brutine,
FIG. 5A shows the operation when the operation mode selection key (51) is operated. That is, first step (^2
01), it is determined whether the flag (MCSF) is rOJ. The flag (MCSF) indicates the state of input change by the operation mode selection key (51), and is set to rOJ in advance at the initial setting step (A0) in FIG.

If it is determined to be "0" in this step (^201), then in the next step (^202) it is determined that the operation mode selection key (51) is ON, that is, the ON edge is determined, and the result is determined in step (^202).

) is turned off (step (^212)).

On the other hand, in the above step (^201), the flag (M
CSF) is determined to be "1", step (^202'
), and here it is determined whether the operation mode selection key (51) is turned on.

When the key (51) is turned OFF, step (
A204) immediately sets the flag (MC3F) to "0".

FIG. 8(B) shows the operation when the memo ear selection key (50) is operated. First, step (A213
), it is determined whether the flag (MEMOF) is "0". The flag (MEMOF) indicates the state of the input change by the memo edge selection key (5o), and is set to "0" in advance at the initial setting step (80) in FIG.

If rOJ is determined in this step (8213), in the next step (A214), it is determined that the memo ear edge selection key (50) is ON, that is, ONN fluoresce, and in step (A2
15) Set 7 lag (MEMOF) to "1". Then, in step (A217), it is determined whether or not the memo listening mode is currently set, and if it is, step (A218) is performed. State Wu.

FIG. 9 is a chart 70 showing details of the document transport subroutine.

(STFEED) in FIG. 9 is a status counter that indicates the state of document transport, and is set to "0" in advance at the initial setting step (80) in FIG. 7, and changes from "1" to "9". do.

First, in step (A301), it is determined whether this (STFEED) is rOJ. If it is determined to be "0", it is determined in step (A302) whether copying is possible or not.
If it is determined that it is possible (determined in step A413), the document empty sensor (12) determines that the document is not empty in the next step (A303).
A304), the print key (21) on the ADF side is turned on.
When the ON edge is determined, step (A305
), turn the transport bell (33). Then, step (A306) following step (A305)
Then, (STFEED) is incremented to "1". If the above judgment step branches to the negative side, the process directly returns to the main routine. Note that in the above step (8304), it is determined whether the print key on the ADF side is ON, but it may be taken as a step to determine whether the print key on the copying tree side is ON. In this case, the ON edge signal is communicated from the first CPU (201) to this CPU (202).

When the status counter (STFEED) becomes “1”,
When this is determined in step (A307), in the next step (A308), it is determined whether the belt hole sensor (35s) detects the belt hole (35h) and is turned on.

If it is not turned on, it will return to the main routine, but
When the ON edge is determined, it is determined in step (A309) whether the memo ear side mode is set, and the timer T1 and timer T2 are set according to the result of this determination.Step (A310) and step (A311) ), (S
TFEED) is incremented. Timer T1 has
A value is set until the memo setting section (34) is located at the right end of the conveyor belt on the opposite side of the document glass (3), and on the other hand, the value is set in timer T2 until the memo setting section (34) is located at the right end of the conveyor belt on the opposite side of the document glass (3). The value up to the left edge of the side is set.

Therefore, the latter value is much longer than the former value. That is, in the former case, the time is short in order to synchronize the memo setting section and the leading edge of the document, and in the latter case, since there is no need to synchronize with the conveyance of the document, a long time is set so that the memo setting section is positioned above the conveyor belt. .

When (STFEED) becomes “2”, step (A
312), the next step (A313) is performed.
), it is determined whether timer T1 or timer T2 has expired. If it has not finished, return to the main routine. If it is determined in this step that the timer has ended, the document feed roller (22) is moved in step (A314).

At the same time as the document transport roller (23) is rotated, the transport bell (33) is stopped in step (A315). Then, in step (A306), the status counter (
Increment STFEED).

In Figure 9 (B) 1, at Ste Nbu (8316),
If it is determined that (STFEED) is "3", then in the next step (A317) it is determined whether the document feed sensor (24) is ON, that is, the ON edge. When the ON edge, that is, the leading edge of the document is detected, in step (A318), the conveyor belt (33) is rotated again, and the rotation of the paper feed roller (22) is stopped. And the connecting terminal (1)
) and increment (STFEED) in step (8 306).

When (STFEED) is "4", if this is determined in step (8319), the next step (A3
In step 20), it is determined whether the document feed sensor (24) is OFF, that is, whether the trailing edge of the document has passed the second sensor. When the OFF edge is determined, the document transport roller (23) is stopped in step (8321), and the next step (A
322) sets timer T3. And (STFE
ED) and returns to the main routine. Timer T3 indicates that the rear edge of the document is on the document table plus (3
The time required for transport to the right end reference position in 3) is set.

When the status counter (STFEED) becomes "5" and this is determined in step (8323), step (833) is executed.
In step 24), it is determined whether or not the previously set timer T3 has expired. If not finished, connect terminal (e)
Return to the main routine via. On the other hand, if the end is determined here, the conveyor belt is stopped in step (A325). Then, in step (A326), a signal for permitting the copying operation is generated, and the first CPU (201)
Send to. The status counter (STFEED) is incremented to "6". At the end of the process at (STFEED)=5 above, the relationship between the memo set section (34) and the document is in the state shown in the fourth screen.

(STFEED) becomes “6” and step (A32
When this is determined in step 7), in the next step (8328), it is determined whether the copying operation has been completed. This is based on a copy completion signal sent from the copy mature tree side. When the end is determined, the process proceeds to step (A329), where,
The motor (231) is started to rotate the transport bell (33) and the document ejection roller (41). Increment (STFEED) to "7".

In FIG. 9(C), when (STFEED) becomes "7" and this is determined in step (A330),
In the next step (A331), the ejection sensor (42) detects the leading edge of the document and outputs the ON edge.
D) Make it 8 J. When STFEED is determined to be "8" in STEP (8332), it is determined in the next step (8333) whether the trailing edge of the document has passed, that is, the OFF edge of the ejection sensor. When the passage is confirmed, the conveyor belt and the discharge roller pair are stopped in step (A334'). Then, (STFEED) is incremented to "9".

When (STFEED) is "9", if the document empty sensor (12) does not detect a document in step (8335), (STFEED) is set to "0" in step (A336). and prepare to set the original again. On the other hand, if detected, step (A337
), set (STFEED) to "1", and repeat the document feeding process, that is, the above process.

FIG. 10 is a 70-chart showing details of the conveyor belt position changing subroutine.

In the figure, first, in step (A401), it is determined whether the status counter (STFDBT) is "0".

(STFDBT) indicates the state of change in the conveyor belt position for setting memo sheets, and is previously set to "0" in the initial setting step (A0) in FIG. 7.

When it is determined that (STFDBT) is "0", it is determined in step (8402) whether copying is not possible. That is, it is determined whether the position of the memo setting section (34) on the conveyor belt is inappropriate in the memo edge mode. If it is determined that copying is not possible, the conveyor belt is rotated in step (^403). In step (^404), the state counter (STFDBT) is incremented to "1".

When (STFDBT) is "1", if this is determined in step (^405), the next step (^4
In 06), it is determined whether the belt hole sensor (35s) is ON. In this step, when the ON edge signal at the belt hole (35h) is detected, the process proceeds to step (^407).
Then, set timer T4 and then set (STFDBT) to "
2". A value is set in the timer T4 until the memo setting section (34) reaches the memo setting position (P) shown in FIG.

When (STFDBT) is "2", it is determined in step (8411) whether the timer T4 ends. If it has not been completed, the process branches to step (^408), where the document I presser, that is, the DF section (10
3) is opened. If this DF section is opened when (STFDBT) is in the state of "2" or "1", the process proceeds to the next step (^409) and the conveyor belt is stopped. And step (^41
0), return (STFDBT) to "0" and change the conveyor belt position again from the beginning.

When it is determined in step (^411) that the timer T4 has ended, in step (^412) the transport bell F is stopped, and in the next step (^413), copying is designated. If you press the memo edge selection key (50) while not in the memo edge mode, copying will not be possible at step (^221) in Figure 8 (B), and step (^222) will be disabled.
), the memo mode is activated. Then, the determination in step (^402) in Fig. 10 becomes YES, and in step (^403) the conveyor belt rotates and the memo section (
34) reaches the settable position (P), the conveyor belt stops at step (8412). Next, the conveyor belt rotates after the print key (21) on the ADF side or the print key on the copying machine main body side is pressed, and then the DF section (1
Even after closing 03), it is possible to replace the memo slip.

Next, according to the 70-chart shown in Figure 11 and after, the first
An overview of the operation control of the copying machine main body (1) performed by the CPU (201) will be explained.

Figure @11 is a general 70-char of processing operations.

First, in step (SO), initial settings are performed. Next, in step (SL), an internal timer built into this CPU is set and started. Step (S
In 2), it is determined whether or not copying is in progress. If copying is in progress, the process skips to step (S5); otherwise, the process proceeds to step (S3).

Step (S3) is an automatic paper selection (8th PS) subroutine that automatically selects the most suitable paper based on the document size detected on the ADF side and the copy magnification set on the copying machine main body side. In the figure, a 70-chart of the main part related to the memo ear mode is shown.

Step (S4) is automatic magnification selection (8M
FIG. 13 shows a 70-chart of the main part of the subroutine S) related to the memo ear mode.

Step (S5) is a step for performing processing other than the processing shown in the main routine, such as interrupting the second CPU (202) and communicating data of the original size. Step (S6) is a copy operation subroutine that executes a series of well-known electrostatic copying sequences.

In step (S)), it is determined whether the internal timer set in step (Sl) above has ended, and when the internal timer has ended, step (S
Return to step 1) and repeat this loop. The end of the clock value of the software timer (counter) used in steps (S3) to (S6) is determined based on the count value in units of time set in this internal timer.

Now, in the automatic paper selection subroutine in Figure 12,
In step (S301), it is determined whether the data transmitted from the ADF side is the automatic paper selection mode. Otherwise, the paper selection remains the same, that is, the operation panel section (4
) is the paper selected and displayed. It is automatic paper selection mode, and in step (302) the ADF
If it is determined that the document is in the memo edge mode, it is set as a suitable paper with a copy magnification x (original length + memo set manager). If you are not in memo ear mode, in step (S304), as usual,
Applicable paper is copy magnification x original length.

In step (S305), it is determined whether a sheet larger (longer) than the set compatible sheet is loaded and can be fed. If so, step (S306)
, the paper that is equal to or larger than the compatible paper and whose size is closest to this compatible paper is selected. In step (S305), if there is no paper corresponding to the compatible paper determined in step (S303), the paper selection is not changed and step (S307
), the operation mode is set to manual.

The more specific operation of the above-mentioned so-called APS and the operation of the AMS described later are well known from, for example, Japanese Patent Application Laid-Open No. 109072/1983, and therefore detailed explanations will be omitted. Here, a specific example of the process 70- in FIG. 12 will be explained. When it is not in the memo ear mode, it is the same as the conventional APS.

In the memo edge mode, when the document is A4 (vertical) and the magnification is i, ooo, the length is 297+20=317.
Paper that satisfies the width≧210, i.e. A3 (vertical) or B
4 (vertical), etc., and if these are selectable, the smallest size (B4 (vertical)) is selected.

If the document is A4 (vertical) and the magnification is 0.900, the length ≧
(297+20)Xo, 900=285 width≧210X0
．． Paper that satisfies 900=189, i.e. A3 (vertical), B4 (vertical), A
4 (vertical) is selectable. Among these sheets, the loaded paper of the smallest size, for example A4 (vertical), is selected.

When the document is A4 (vertical) and the magnification is 1.414, length ≧ (297 + 20) Xl, 414 = 448 width ≧ 21
0X1,414=297. For example, if the maximum copyable paper is A3, there is no paper that satisfies the above conditions, so the mode is automatically switched to manual as shown in step (S30)). , leave it to the user's choice.

FIG. 13 is a flowchart showing details of the automatic magnification selection subroutine.

In step (S401), it is determined whether the transmission from the ADF is in automatic magnification selection mode. Otherwise, the selection made with the main unit operation keys remains unchanged without changing the copy magnification. If it is determined that the automatic magnification selection mode is in effect, and if it is determined in the next step (5402) that the memo edge mode is selected, in step (S403'), the selected paper length/(original length + memo set manager) is temporarily set. Set as the applicable magnification. When not in the memo edge mode, the selected paper length/original length is used as the compatible magnification, as in the past.

In step (S405), it is determined whether the set suitable magnification is within the magnification change range of the main body of the copying machine. If applicable, in step (S406), the applicable magnification is set as the actually applied copying magnification. If it is determined in step (S405) that it is not applicable, the process proceeds to step (S407), where the operation mode is set to manual.

A specific example of this AMS is shown below, and it is of course exactly the same as the conventional AMS when it is not in the memo ear side mode.

In the case of the memo edge mode, the memo set manager in this embodiment is set to 20 (dragon), and its width is the minimum copyable paper width of A5 (vertical), 148 (Iem). If the manuscript is A4 (vertical), its length is 297
(Iem), if the selected paper is A4 (vertical), the copy paper length is 297 (ms), and the copy magnification (M) at this time is M (vertical) = 297/(297+20) = 0 .937 If the original is A4 (vertical) and the selected paper is A4 (9 sheets), then M (vertical) = 210/(29-7+20) = 0.662
In the above case, the above magnification is applied because copies are made without problems in the width direction as well.

On the other hand, if the original is A4 (horizontal) and the selected paper is A4 (vertical), M (vertical) = 297/(210 + 20) = 1.291, and at this magnification, the original image (38h +
m) >copy paper (210+nm), and there is a range of the original that is not copied. To avoid this, in such a case, the magnification is determined also in the width direction. That is, M (horizontal) = copy paper width/original width = 210/297 = 0
．． 707 Also, if the original is 84 (vertical) and the selected paper is 85 (horizontal), M (vertical) = 182/(364 + 20) = 0.474, and the possible copy magnification range is 0.640 to 1,420. The above magnification cannot be applied to copiers up to
As shown in step (S407), the mode is automatically switched to manual and the user's selection 'I

As described above, the contents of the memo slip as additional information can be extremely easily captured together with the original image, and the selection thereof is also extremely easy. In the above embodiment, the memocent portion (34) is formed by cutting the conveyor belt into a rectangular shape, but the memocent portion (34) is not particularly limited to this. for example,
It is also possible to form a recess at a predetermined location on the conveyor belt using a press or the like, provide a transparent sheet to cover the recess, and insert a piece of memo paper through at least one of the openings. Further, it is also possible to provide a holding section for memo paper pieces without processing the conveyor belt. For example, members for supporting the four corners of the memo sheet may be attached to the conveyor belt. Furthermore, instead of processing the conveyor belt or attaching members, it is also possible to simply removably attach memo set pieces to the conveyor belt. You can choose a simple method such as using adhesive on the back side of the memo strip or securing the memo strip with transparent tape. However, even in these cases, it is necessary to clearly indicate the position of the holding section on the conveyor belt where the memo sheet is provided.

Although it is related to the position of the holding part, in the above embodiment, the memo holding part was single and elongated in the width direction of the conveyor belt, but the present invention is not limited to this. The shape may be elongated in the longitudinal direction. The location is generally at the periphery on both sides of the conveyor belt. If there are multiple positions, one is selected and controlled to synchronize with the movement of the document.

Furthermore, in the above embodiment, the movement of the conveyor belt is detected by a hole provided in the conveyor belt and a belt hole sensor that detects the hole. It is also possible to provide a rotary encoder on the rotating shaft of the motor that drives the belt, thereby constantly monitoring the reference position on the conveyor belt or the movement of the holding portion of the sheet-shaped body.

As is clear from the above description, according to the present invention, a copying machine of a type that exposes an original by the movement of a scanner can be connected with at least an original transport device that transports the original using a transport belt. In this case, additional information can be imprinted independently of the main body of the copying machine, and setting of the additional information is easy, and it is also extremely easy to select whether to imprint or not. Furthermore, basically, the position of the holding section that holds the sheet-like object that displays additional information is set, and a means for controlling the movement of the document and the change in the position of this holding section is additionally provided. Since it only needs to be installed, there is no cost increase, and the functionality is greatly improved, so it is cost-effective.
