The operation panel 3 is provided on the upper surface of the apparatus main body 31. The operation panel 3 is for inputting various instructions and setting contents, and for displaying operation contents and the like.

The apparatus main body 31 is further connected to a handy scanner 60 capable of reading arbitrary additional information including image data. The handy scanner 60 can read data in an area of, for example, 64 mm × 10 mm in 80 lines by one operation by manually scanning.

FIG. 1 is a block diagram showing an electrical configuration of the above-described image recording apparatus.

This image recording apparatus is provided with a CPU 1 as a control center. The CPU 1 has an operation panel 3, a cassette size detection unit 4, a thermal head 5 included in an additional data recording mechanism 39 via an input / output interface 2, Solenoid 6 for lifting and lowering the head, ink ribbon motor 7, control CPU 1 '
, The main motor 9, the stepping motor 10 and the handy scanner 60 are connected.

The CPU 1 also includes, as storage means, a font ROM 11, a program ROM 12 in which an execution program is written, and a RAM 13.
Is connected. The font ROM 11 is a read-only memory in which character data and the like are stored in advance. When the additional data recording mechanism 39 records additional data including characters such as specific characters and numerals, data indicating the character is stored in the font ROM 11. Is read from.

In this embodiment, the font ROM 11 has a vertical character font area and a horizontal character font area, and the same additional data is previously written in each of the font areas.

The RAM 13 has a buffer area 14, a first memory area 15

The cassette size detector 4 detects the size of the sheet cassettes 47 and 48. That is, there are a plurality of paper feed cassettes, for example, a B5 vertical feed and a B5 horizontal feed for a B5 paper feed cassette, and a plurality of B5 and A4 paper feed cassettes for the same vertical feed. Then, it is possible to specify a sheet cassette of one size in the vertical and horizontal directions with respect to the size of these sheets. For detecting the size of the sheet cassette, for example, a barcode label or a plurality of magnets are arranged at an appropriate position on the outer surface of the leading end of the sheet cassette, or a plurality of irregularities are arranged to form a code of several bits. Then, reading means utilizing light and magnetism is arranged on the main body side, and the size of the sheet cassette is read by the reading means.

By detecting the size of the sheet cassette, the direction of the recording sheet in the conveyance path with respect to the conveyance direction is detected.

FIG. 3 is a diagram showing the relationship between the direction of the recording paper in the transport direction and the recording direction of the additional data. Note that, in the drawing, the arrow indicates the recording paper conveyance direction, and P indicates the paper.

FIG. 3A shows a vertically transported state, and FIG. 3B shows a horizontally transported state. In FIG. 9A, the additional data is recorded horizontally for vertical communication, while in FIG. 10B, the additional data is recorded vertically for horizontal communication.

Thus, it is preferable that the additional data recorded on the recording paper P correspond to the direction of the characters recorded on the recording paper. By the way, the direction of the normal recording paper and the direction of the character to be recorded usually coincide. Focusing on this point, the present invention detects the direction of the recording paper instead of the direction of the character.

The thermal head 5 prints additional data on recording paper. The head lifting solenoid 6 raises and lowers the thermal head 5 with respect to the recording paper transport path.
The ink ribbon motor 7 winds the printed ink ribbon by a predetermined length, for example, at least a printing width of the additional data.

Next, a specific example of the operation panel 3 is shown in FIG. Since the operation panel 3 has an elongated flat shape, FIG. 2A shows the left half of the operation panel 3 and FIG. 2B shows the right half separately.

The operation panel 3 includes operation keys 3a necessary for operating the image recording apparatus and a display 3b including a liquid crystal multi-screen.
(See FIG. 1).

Among them, the keys specific to this embodiment are the operation keys 3a,
Mode selection key 17, display content selection key 18, shift key 22
And a print key 23.

Each time the mode selection key 17 is pressed, that is, every time a signal from the mode selection key 17 is given to the CPU 1, the operation mode of the image recording apparatus is switched. Which mode the operation mode is in is indicated by mode lamps 19 to 21. That is, the scan mode, the print mode, the function mode, or the normal mode in which all the lights are turned off are represented by which of the scan mode lamp 19, the print mode lamp 20, and the function mode lamp 21 is turned on.

When a desired mode is selected by the mode selection key 17, various displays are performed for each mode by the liquid crystal multi-display 3b. In the printing mode, for example, “circulation”, “reference”, “important”, “urgent circulation”, and “confidential”
Etc. appear as additional data. The display of the character message is performed by being read from the font ROM 11 and temporarily stored in the buffer area 14.

It should be noted that the data recorded in the font ROM 11 is the above-mentioned 5
The data is not limited to the type, and may be other data.

The liquid crystal multi display 3b is, for example, as shown in FIG.
It is divided into eight pixel areas of 0 to 7, and one character is displayed on each pixel. In the example of FIG. 4, the word "important" is displayed at the third and fourth pixels.

When the print mode is selected by the mode selection key 17, the lower key of the liquid crystal multi-display 3b functions as the shift key 22. That is, this shift key
22 is composed of those shifting the pixel positions of the characters displayed on the display panel 3b, a right shift key 22 _R and the left shift key 22 _L (Figure 2). Right shift key 2
When 2 _R is depressed once, as shown in FIG. (B), the display characters from the home position display state of FIG. (A) it is shifted to the right by one pixel. Further, when the left shift key 22 _L is pressed once, as shown in FIG. (C), the display characters from the home position display state of FIG. (A) is shifted to the left by one pixel. And right and left shift keys 22 _R , 2
Either 2 _L of sequentially display characters for each pressed is shifted to the left and right.

 The display characters are shifted as follows.

The first method is to change the write address when reading the additional data selected from the font ROM 11 and writing it to the buffer area 14. That is, a write address generating means (not shown) can change the address of one pixel of the liquid crystal multi-display 3b, and changes the write address each time based on information on the number of shift operations from the shift key and the shift direction. Then, writing is performed from the font ROM 11.

Further, as a second method, when the additional information once stored in the buffer area 14 is read and output to the liquid crystal multi-display 3b or the thermal head 5, the read address may be changed according to the shift information. Good.

When the liquid crystal multi-display 3b is not divided into pixels, the address can be changed not only for one pixel but also for one address or for each desired address.

Next, a configuration and operation for recording the additional data stored in the buffer area 14 on a sheet by the additional data recording mechanism 39 including the thermal head 5 will be described.

FIG. 5 is a cross-sectional view showing a more detailed configuration of the additional data recording mechanism 39 in this embodiment. FIG. 5A shows a standby state of the additional data recording mechanism 39, and FIG. 39 illustrates the operating state of the device.

5 (a) and 5 (b), a fixing discharge roller 62 is provided at the exit of the fixing device 38, and a paper detection switch 8 is provided on the downstream side in the paper transport direction. When the leading end of the sheet is discharged from the fixing discharge roller 62, the sheet detecting switch 8 is turned from a solid line to a state shown by a dashed line, and is turned on. Is a switch that returns to the solid line state and is turned off at the moment of passing through. Therefore, the trailing edge of the sheet is detected by detecting the edge at which the sheet detection switch 8 is switched from on to off.

The paper discharged from the fixing discharge roller 62
To the downstream side in the transport direction. On the downstream side of the transport roller 64, a switching claw 53 is provided near the transport roller 64. As described above, the switching claw 53 guides the sheet toward the discharge roller 65 in the solid line state, and in the state indicated by the dashed line,
The sheet is guided to the re-feeding mechanism 41 side.

An additional data recording mechanism 39 and a punching mechanism 40 are sequentially provided on a path through which the sheet guided to the discharge roller 65 by the switching claw 53 passes.

The additional data recording mechanism 39 includes a platen roller 66 and a thermal head 5 that can be moved up and down, which are arranged on a paper transport path. As shown in FIG. 5 (a), the thermal head 5 is moved upward from the platen roller 66, and as shown in FIG. 5 (b), the head line is lowered when the head line contacts the peripheral surface of the platen roller 66. It can be displaced to the state.

More specifically, a mounting member rotatable about a support shaft 67.
68 is provided, and the thermal head 5
Attached to 68. Normally, a clockwise moment in the drawing is applied to the mounting member 68 by a reaction force due to the contact of the leaf spring 70 with the casing 69 of the additional data recording mechanism 39 and a return spring 71. As a result, the thermal head 5 It is waiting at a position raised from the roller 66. A cam 72 is engaged with the mounting member 68. cam
72 is turned 180 degrees by a head lifting solenoid 6 (not shown) (see FIG. 1), and when turned, the mounting member 68 is turned counterclockwise as shown in FIG. Rotate. Thereby, the thermal head 5 is lowered against the reaction force of the leaf spring 70 abutting on the casing 69, and when the thermal head 5 abuts on the peripheral surface of the platen roller 66, the abutting force is kept constant by the action of the leaf spring 70. Will be kept.

The additional data recording mechanism 39 further includes a pair of ribbon pulleys.
An ink ribbon 75 is provided between the ribbon pulleys 73 and 74. The ink ribbon 75 covers the head line of the thermal head 5. Therefore, when the thermal head 5 comes into contact with the peripheral surface of the platen roller 66 as shown in FIG. 4B, the ink ribbon 75 comes into contact with the head line of the thermal head 5,
When the thermal head 5 is driven, the ink on the ink ribbon 75 moves toward the platen roller 66, that is, toward the recording paper.

The ink ribbon 75 has a color different from the color on which the document image is recorded, for example, when the document image is recorded in black,
Preferably, the ink ribbon 75 is red. of course,
An ink ribbon 75 of the same color as the color of the original image may be used.

In this embodiment, the cam 72 is rotated by 180 degrees by the head raising / lowering solenoid 6, thereby raising and lowering the thermal head 5. However, the thermal head 5 may be raised and lowered directly by the solenoid.

The cam 72 may be rotated by a motor. Further, the thermal head 5 may be fixed on the paper transport path, and the platen roller 66 may be moved up and down.

Next, a control operation of the additional data recording mechanism 39 will be described with reference to a time chart shown in FIG.

Transport roller 64, discharge roller 65, and platen roller 66
Are driven by the stepping motor 10 (see FIG. 1) as described above. Therefore,
Unlike the fixing discharge roller 62 of the fixing device 38 driven by the main motor 9, the rotation speed can be changed.

In a state other than the operation state where the thermal head 5 is lowered as shown in FIG. 5B, the paper discharged from the fixing device 38 must be conveyed in the discharging direction without being slackened or pulled. No. Therefore, when the additional data recording mechanism 39 is in the standby state, the transport roller 64 and the discharge roller 65
The platen roller 66 is rotated by the stepping motor 10 at, for example, 300 mm / sec. This speed is controlled by the paper transport mechanism 37 driven by the main motor 9 and the fixing device 38.
Speed equal to the speed of

When the sheet is discharged from the fixing device 38 and the rear end of the sheet has passed through the sheet detection switch 8, the sheet detection switch 8
Switches from on to off. The step motor 10 is stopped after a predetermined time t seconds from the detection of the off-edge. By stopping the stepping motor 10, the trailing edge of the sheet is moved to a predetermined position, for example, several tens of
Stopped at the position of mm. After 100 msec from the stop of the stepping motor 10, the head lifting solenoid 6 is turned on and the ink ribbon motor 7 (see FIG. 1) is started. Thereby, the operation of the additional data recording mechanism 39 is started. In this case, the ink ribbon 75 is interposed between the thermal head 5 and the peripheral surface of the platen roller 66 near the rear end of the sheet.

After the head lifting / lowering solenoid 6 is turned on, for example, 30
After 0 msec, the stepping motor 10 is driven intermittently one step at a time, and is driven for 80 steps. Then, additional data for one line is sequentially recorded by the thermal head 5 every time the stepping motor 10 is stopped. As described above, the stepping motor 10 is stopped for each line, and the additional data is recorded by the thermal head 5, so that the contents of the additional data are clearly recorded.

Further, since the recording of the additional data is performed at the rear end of the copied paper, a part of the paper does not remain in the fixing device 38, and there is no fear that the paper is deformed or scorched.

After the stepping motor 10 is operated for 80 steps (corresponding to 80 lines of the handy scanner 60), it is temporarily stopped,
The head lifting solenoid 6 is turned off, and the thermal head 5 is raised by the reaction force of the leaf spring 70 and the restoring force of the return spring 71. Since the ink ribbon motor 7 continues to rotate for, for example, 200 msec during and after the thermal head 5 is raised, the ink ribbon 75 fed out at the time of printing is smoothly wound up, and the ink ribbon 75 remains attached to the paper. It does not become loose or loose.

After the elapse of 200 msec, the stepping motor 10 is stopped and then rotated at a constant speed for a fixed time. As a result, after the additional data is recorded at the rear end of the sheet, the sheet is discharged from the discharge roller 65 to the discharge tray 52.

Then, in case of continuous copying, stepping motor 10
Returns to the same speed as the original 300mm / sec main motor 9,
In the case of a single copy, the operation is stopped.

In this embodiment, a paper detection switch 8 is provided at the discharge section of the fixing device 38, and the trailing edge of the paper is detected based on the edge at which the paper detection switch 8 switches from on to off, and the recording position of the additional data is determined. Although the control is performed so as to be at a desired position, the trailing edge position of the sheet is detected based on the registration switch provided at the registration roller 50 (FIG. 7) instead of using the sheet detection switch 8 as a reference. Alternatively, the recording position of the additional data may be determined.

In the case where the ejection confirmation switch 76 is provided in connection with the ejection roller 65, if the paper size is known, after the ejection confirmation switch 76 detects the leading edge of the paper, the additional data is May be determined.

Further, since the distance from the registration roller 50 to the additional roller recording mechanism 39 is constant, if the paper size is known, the additional data recording timing is controlled based on the paper feed timing by the registration roller 50, and the paper Additional data can be recorded at a desired position. In other words, the position of the sheet can be obtained by calculation without detecting the sheet by the specific sheet detection switch, thereby controlling the recording position of the additional data.

In the above description, the case where the one-sided normal copy is performed is mainly described. However, in the case of the two-sided copy or the composite copy, the additional data is output immediately before the copied paper on which the copy is completed is discharged to the discharge tray 52. Will be recorded.

FIGS. 8 and 9 are flowcharts showing the operation of the image recording apparatus according to the present invention.

In the flowchart of FIG. 8, the orientation of the recording paper is determined by detecting the sizes of the paper feed cassettes 47 and 48, and the additional data in the corresponding orientation is output from the font ROM 11.

In the state where this flowchart is started, it is assumed that the print mode is selected by the mode selection key 17 on the operation panel 3 and desired additional data, for example, "important" is selected.

Then, when the print key 23 (see FIG. 2B) is pressed, each operation for copying is started (step S1).
S ₁ ). First, whether printing mode is selected it is determined (step S _2). Here, when it is already printing mode release (NO in step S _2), the normal copying operation is carried out as it is (Step S _3).

On the other hand, when it is subsequently print mode is selected is determined based on (YES at Step S _2), then the size of the paper feed cassette of the cassette size detecting unit 4 detecting result (Step S _4). That is, the paper of the paper feed cassette is if the horizontal through (horizontal in step S _5), the process proceeds to step S _6. In step S _6, as the horizontal through the sheet cassette is attached, the font ROM1 to cope with this
Character font "important" from within the vertical font area (for horizontal communication) (corresponding to Fig. 3 (b))
Is temporarily taken into the buffer area 14. When the import of the character font to the buffer area 14 is completed, the copying operation is performed (Step S _8).

On the other hand, paper feed cassette if the horizontal through (vertical in step S _5), the process proceeds to step S _7. In step S _7, as the vertical through the sheet cassette is attached, (as for longitudinal through) "critical" character fonts that (FIG. 3 from landscape font area of font ROM11 to respond to this (Corresponding to (a)) is temporarily stored in the buffer area 14 as described above. And after this, the copy operation is performed (Step S _8).

After the original image is copied on the paper fed from the paper cassette by the image processing unit 35 and is fixed, the fixing discharge roller
When the sheet passes through the sheet detection switch 8 via 62, the sheet is stopped so that its rear end is located on the platen roller 66 after a predetermined time. Character font "important" from the buffer area 14 in this state is transmitted to the thermal head 5 is printed on the rear end position of the sheet is performed (step S _9, the third
Figures (a) and (b). When the printing is completed, the paper is discharged to the paper discharge tray 52, thereby ending a series of copying operations.

 Next, the flowchart of FIG. 9 will be described.

In the flowchart of FIG. 9, the orientation of the recording paper is determined by detecting the sizes of the sheet cassettes 47 and 48, additional data in the corresponding direction is output from the font ROM 11, and the character font is shifted within a predetermined range. Is what you do.

First, in step S _11, the printing mode is selected by the mode selection key 17 on the operation panel 3, a desired additional data,
For example, "important" is selected.

Subsequently, whether the shift key 22 has been pressed it is determined (step S _12). Without shift key 22 is pressed, when the print key 23 is pressed, steps S ₁₅ ~
The eighth FIG similar operation is performed in step S _19. This is a case where the shift operation is not performed on the character to be printed.

On the other hand, when the print key 23 is pressed after the shift key 22 is operated (while confirming on the liquid crystal multi display 3b),
Each operation for copying is started (step S _20).
Then, shift processing for the shift operation is performed (step S _21). This shift processing is based on the home position and the shift amount described with reference to FIG. 4. A = home position−shift amount (1) where the right shift key 22 _R is minus and the left shift key 22 _L is plus. In the example of FIG. 3, it is obtained from "3".

That is, when the right shift key 22 _R is pressed once in the example of the FIG. 4, the (1) A from the equation is a 4 (i.e., the state of FIG. 4 (b)). When the right shift key 22 _R is pressed twice, A is 5, and the is one pixel shifted further to the right.

On the other hand, when the left shift key 22 _L is pressed once, A is a 2 than the (1) equation (i.e., the state of FIG. 4 (c)). When the left shift key 22 _R is pressed twice, A is made to be 1, and the one pixel shifted further to the left.

In step S _22, to create an address when capturing from the font ROM11 in the buffer area 14 based on Motoma' value A from the equation (1), and stores the address.

Further, the direction of the sheet cassette is subsequently determined from the detection result of the cassette size detection unit 4 (step
S _23). Thereafter, the process proceeds to step S ₂₅ or step S ₂₆ depending on the size of the paper feed cassette is selected discrimination result of the response to the orientation and direction of the character font "important", according to the address of the stored based on the value A The data is taken into the buffer area 14. Then, as described above, when the paper on which the document is recorded is conveyed to the platen roller 66 and stopped, the document is transmitted from the buffer area 14 to the thermal head 5 in a content according to the direction and shift operation of the paper, and the document is transmitted. is printed in the rear end position (step S _27, S _28).

In this embodiment, the calculation of the shift position is performed according to the above (1).
Although the description has been made using the equations, various methods of calculating the display position of the character with respect to the home position from the shift operation can be considered, and the present invention is not limited to the above equation (1). Also, instead of two shift keys on the left and right, a key corresponding to each pixel may be provided.
A key that can be cyclically shifted by the number of keys may be used.

〔The invention's effect〕

As described above, according to the present invention, the direction of the document in the transport direction is detected by the cassette size detecting means, and the direction of the character constituting the additional information is determined to correspond to the direction using the detection result. Therefore, it is possible to automatically match the direction of the image information with the direction of the character constituting the additional information. In addition, complicated confirmation is not required.

Further, since the additional information to be printed can be shifted within a predetermined range, it is possible to obtain a certain degree of freedom in the printing position and to provide a recording sheet on which the additional information is recorded with good appearance.
