[Prior Art] Conventionally, there have been serial printers in which a carriage carrying a recording head is moved in the longitudinal direction of a platen to perform recording in a serial manner, and a line head is provided that is almost orthogonal to the scanning direction of the recording paper to perform printing on a line-by-line basis. There are line printers that perform recording. There are also recording devices, such as facsimile machines, that photoelectrically read a document and record it line by line.

[Problems to be solved by the invention] Each of these printers has its advantages and disadvantages.For example, line printers have faster printing speed than serial printers, but line printers use more ink ribbon than thermal transfer printers. This increases running costs. On the other hand, when recording image information or the like on thermal paper using a thermal head or the like, a line printer is more advantageous than a serial printer because it has a faster recording speed.

In this way, if you use a facsimile device, for example, you can read image information and record it line by line on thermal paper to form an image, but if you want to print a document output from a word processor on plain paper, etc. , a separate recording device must be prepared, and conventionally there has been no single device that satisfies both functions.

The present invention has been made in view of the above-mentioned conventional example, and provides a reading and recording device that can photoelectrically input a document and selectively perform sequential recording or line-by-line recording using a single device. The purpose is to

The apparatus includes a second conveying means for conveying the paper, and a line recording means for recording line by line on the recording paper that has reached the second recording position.

[Operation] In the above configuration, the stacking means capable of stacking a plurality of sheets conveys the sheets through the conveyance path to the first recording position, and the serial recording means sequentially records the sheets that have reached the first recording position. Record with . A reading sensor section is provided in this conveyance path, and the sheet can be read manually by photoelectrically reading the sheet.

The rotation of the paper feed motor 103 is transmitted.

[Description of the entire mechanism section (Figs. 4 and 5)] Fig. 4 is an external perspective view of the mechanism section of the reader printer according to the embodiment with the front cover removed, and Fig. 5 further shows the carriage section and upper frame. FIG. 2 is a perspective view of the mechanical section excluding the parts, with a part cut away for explanation. Note that common parts in each drawing are indicated by the same symbols.

In FIG. 4, 201 is a ribbon cassette storing an ink ribbon, and 200 is a carriage. The carriage 200 is driven by a shaft 20 by a carriage motor 102.
2 in the direction of arrow A, approximately parallel to the flat platen 203. 203 is a flexible member such as a rubber member provided at a position facing the thermal head 101 mounted on the carriage 200. The recording paper is conveyed between the ink ribbon and the flat platen 203 by the counterclockwise rotation of the paper feed motor 103, and is pressed by the thermal head 101, and the carriage 2
The data is transferred and recorded serially as the number 00 moves.

204 is a sheet 20 of a plurality of recording papers or original documents to be read;
This is a stacker that can load and store 7 items. Stacker 20
4 are provided with slidable paper guides 205 and 206, the positions of which are adjusted by the operator according to the size of the sheet 207. The positions of these paper guides are detected by a sensor (not shown), and the controller 100 controls the stacker 200 based on a signal from this sensor.
The size of the sheets stored in the can be detected. Therefore, for example, when the length of the reading sensor 111 in the horizontal direction is the horizontal size of A4 size, if the width of the document is A4 size or more, it will not be possible to read or feed the document (if the sheet document is at the contact sensor 105). It is possible to prohibit the conveyance of the sheet by determining that there is a risk of the sheet being caught.

A gear 208 is attached to the motor shaft of the paper feed motor 103, and when the gear 208 rotates counterclockwise, this rotation is transmitted from the gear 209 to the gear 210, which will be described later. The sheet is fed by driving the feeding roller (pinch roller).

Also, when the paper feed motor 103 rotates clockwise,
This rotation is from gear 208.230 to gear 240.241.
can be conveyed to. In this way, the roller 226 is rotationally driven,
The thermal paper 222 is transferred toward the thermal line head 113.

These movements will be explained in more detail using FIGS. 5 to 8.

In FIG. 5, the rotation of the paper feed motor 103 is transmitted to the gear 210 attached to the shaft 314, so that the platen (main roller) 300 is rotationally driven in the direction of the arrow. is cam 302 and 3

The cam 303 is a cam follower 30 of the contact sensor 105 equipped with the preemption sensor 111 and the lamp 110.
5, and the contact sensor 105 can be moved up or down depending on the rotational position of the cam 302. Similarly, the cam 302 engages with the cam follower of the lever 307 to rotate the lever 307 about the shaft 30B, thereby raising and lowering the pickup roller 308.

A lamp 114 and a reading sensor 111 are attached to the contact sensor 105, and as described above, it is configured to be able to come into contact with (down) or separate from (up) the platen 300. When reading a document and in the standby state, the contact sensor 105 is in a down state, and during reading, the light emitted from the lamp 114 is reflected on the surface of the document, and this reflected light is inputted to the reading sensor 111 and converted into an electrical signal. . When transporting a sheet without reading a document, the reading sensor 111 is in an up state and serves as a guide for transporting the sheet to a serial recording position.

A separation roller 309 is attached to the shaft 306 of the lever 307, and when the pickup roller 308 is in the down state (in pressure contact with the sheet), the rotation of the paper feed motor 103 is transmitted to the shaft 308 through gears 208 and 211. and the roller 309 rotates in the direction of arrow B. The rotation of the separation roller 309 is transmitted to the pickup roller 308 by the belt 313, and the rotation of the separation roller 309 is transmitted to the pickup roller 308,
feeds the sheets stored in the

When the pickup roller 308 is up (separated from the sheet), the shaft 306 is disconnected from the gear 211 and the rotation of the paper feed motor 103 is no longer transmitted, and the shaft 306 and the separation roller 309 are free to rotate.

In this way, when feeding the sheet 207 from the stacker 204, the paper sensors 403 and 404 are used to feed the sheet 207.

8 and the movement of the contact sensor 105. FIG.

FIG. 6(A) shows the state when the stacker 204 starts feeding sheets 207 such as recording paper or originals, and FIG. 6(B) shows the state immediately after feeding one sheet 207 or when the thermal head FIG. 6C is a diagram showing the state of the pickup roller 308 and the contact sensor 105 when reading a document or in a standby state.

Normally, in the standby state, the pickup roller 308 is up as shown in FIG. 6(C), and the contact sensor 105
is in contact with the platen 300 by a leaf spring 406 (down state). This is to prevent deterioration of the reading sensor 111 by blocking input light to the reading sensor 111.

In this state, when the sheet 207 is set on the stacker 204 and an instruction is given to feed the sheet, the cams 302 and 303 are rotationally driven in the counterclockwise direction by the pickup motor 104. As a result, the cam follower 402 provided on the lever 307 and the cam 302 have a positional relationship as shown in FIG. 6(A). In FIG. 6(A), the lever 307 is moved in the direction of arrow C from the state shown in FIG. 6(C) around the shaft 306, and the pickup roller 308 is pressed onto the sheet 207 by the leaf spring 405. ing.

At this time, the contact sensor 105 is separated from the platen 300 by the action of the cam 302 and the cam follower 305 against the force of the leaf spring 406, thereby preventing the surface of the sensor 111 from being worn out due to the rotation of the platen 300. .

In the state shown in FIG. 6(A), the leading edge of the sheet is at the separation roller 309.
The paper sensor 403 is in the on state. When the paper feed motor 103 starts rotating counterclockwise in this state, the rotation of the paper feed motor 103 is transmitted to the shaft 306 and the platen 300.

As the shaft 306 rotates, the separation roller 309 rotates, and this rotation is transmitted to the pickup roller 308 by the belt 313. In this way, the sheet 207 is transferred between the separating roller 309 and the separating plate 407 facing the separating roller 309, and only one sheet is separated. Next, sheet 2
07, the paper sensor 404 provided between the roller 401 and the separation roller 309 is turned on.

In this way, the sheet 207 is connected to the platen 300 and the roller 401.
When the cams 302 and 303 are transferred as shown in FIG. 6B, the cams 302 and 303 rotate, and when the cam follower 402 is no longer biased by the cam 302, the pickup roller 308 is moved by the force of a spring (not shown). will be uploaded. This is to prevent the sheets 207 stored in the stacker 204 from being fed continuously. This ensures that the sheets are fed and processed one by one.

Further, FIG. 6(B) shows a state of serial recording by the thermal head 101. In this case, the sheet 207 is sandwiched between the platen 300 and the roller 401, and the sheet 207 is held between the platen 300 and the roller 401.
It is fed in synchronization with the movement of the carriage 200 by the rotation of the carriage 200. On the other hand, when reading a document, the contact sensor 105 is brought into contact with the platen 300 through the document, and the document is transported in synchronization with the reading of the document by rotation of the platen 300. be done. roller 401
is a rotatable roller, and is a pinch roller that is pressed against the platen 300 and rotates in conjunction with the rotation of the platen 300.

When recording the sheet 207 transferred from the stacker 204 using the thermal head 101, the positions of the pickup roller 308 and the contact sensor 105 are as shown in FIG.
B) When reading the sheet 207, the contact sensor 105 is lowered as shown in FIG. 6(C) and the sheet 207 is read. When the recording or reading of one sheet is completed and the feeding of the next sheet is instructed, the pickup roller 308 and the contact sensor 105 are again arranged as shown in FIG. 6(A), and the next sheet is fed. It is fed from the stacker 204.

FIG. 7 is a diagram showing a path for transmitting the rotation of the paper feed motor 103. When the paper feed motor 103 rotates counterclockwise, the gears 209 to 211 and gears 242 and 243 rotate in the directions of the arrows. Cut paper feed section 110

Conversely, when the paper feed motor 103 rotates clockwise, the rotation is controlled by the gear 230 and the gears 240, 241, 2.
28, and finally to a roller 226, where the thermal paper 222, which is a rolled paper, is fed.

FIG. 8 is a diagram showing the structure of gears 209 and 230 that transmit the rotation of the paper feed motor 103.

The shaft portions 710 and 711 of the gears 209 and 230 both have a spring clutch structure. That is, only when gear 208 rotates counterclockwise and gear 209 rotates clockwise, the rotation of gear 209 is transmitted to gear 209-1. On the other hand, gear 230 transmits the rotation of gear 230 to gear 230-1 only when gear 208 rotates clockwise and gear 230 rotates counterclockwise.

In this way, when the paper feed motor 103 rotates clockwise, the gear 209 slips and its rotation is not transmitted to the gear 209-1, and the rotation of the gear 230 is transmitted to the gear 230.
0-1, and only the roll paper feed section 112 is driven. Conversely, when the paper feed motor 103 rotates counterclockwise, the gear 230 idles and the gear 2
09 transmits the rotation to the gear 209-1, and the cut paper feed section 110 is driven.

[Operation Description (Fig. 9) Fig. 9 is a flowchart showing the operation of the reader printer of the embodiment.
Stored in OM.

Before starting this operation, the contact sensor 105 is down and the pickup roller 308 is up, resulting in the state shown in FIG. 6(C). This program is started when an instruction to read or print a document is input from an external device or an operation panel.

First, in step S1, it is checked whether serial recording or reading is to be performed, that is, whether the cut paper feed section 110 is driven. When the cut paper feed unit 110 is driven, the process advances to step S2, and it is determined whether the paper sensor 403 is on. If not, the process advances to step S2, where it is determined that there is no paper error.

If the paper sensor 403 is on, the process advances to step S4;
The pickup motor 104 causes the cams 302, 303
the pickup roller 30 by rotating it counterclockwise.
8 is in the down state, the contact sensor 105 is moved away from the platen 300, and the state shown in FIG. 6(C) is changed from the state shown in FIG.
Transition to state A). In step S5, the paper feed motor 103 starts rotating in the counterclockwise direction to start feeding the sheets stored in the stacker 204.

Next, in step S6, it is determined whether the paper sensor 404 is turned on. If the paper sensor 404 does not turn on even after a predetermined period of time has elapsed in step S7, the process advances to step S8, and error handling such as a paper jam is performed.

When the paper sensor 404 is turned on in step S6, the process advances to step S9 and waits for a sufficient time to have passed for the sheet 207 to be wound around the platen 300 and the pinch roller 401. The sheet 207 is sent between the platen 300 and the pinch roller 401, and the platen 300 and the pinch roller 40
When the sheet 207 is fed six times according to Step 1, the process advances to step S10, and the pickup roller 308 is raised as shown in FIG. 6(B). This results in
Feeding of the next sheet from stacker 204 is prohibited.

In step Stt, it is determined whether the document is to be read or a recording operation is to be performed by the thermal head 101. If reading is to be performed, the process proceeds to step S12, where the leading edge of the sheet document is conveyed to the reading position of the reading sensor 111, and the contact is made. Sensor 105 is brought down. In step S13, each line is read by the reading sensor 111 each time the document is transferred by a predetermined amount, and reading processing such as transmitting the read image signal as a facsimile signal or outputting it from the human output unit 109 to an external device is performed. conduct.

On the other hand, if it is not read in step Sll, step S1
4, it is determined whether the copying process is to read the document using the reading sensor 111 and record it on the thermal paper 222. If it is not a copy process, the process advances to step S15, the sheet is fed to the position of the flat platen 203, and the carriage 200
A printing process is executed in which the thermal serial head 101 scans and records sequentially.

On the other hand, if it is determined in step S1 that the recording operation is to be performed on thermal paper, the process proceeds to step 316, where the sensor 223 checks whether there is thermal paper 222 or not.

If there is no thermal paper 222, the process advances to step S17, and a paper out error is determined. If there is thermal paper 222 in step S16, the process proceeds to step 318, where the paper feed motor 103 is rotated clockwise to transport the thermal paper 222, and in step 519, the thermal line head 113 records one line.

In step S20, check whether recording of all data has been completed,
If it has not been completed, the process advances to step 522 to check whether the printing process for one page has been completed.

When the printing process for one page is completed, the process advances to step S23, the rotation of the paper feed motor 103 is stopped, and the thermal paper 222
is cut into one page size using the cutter 225, and the process returns to step 818 to perform the above-mentioned processing. Step S2
When printing of all data is completed with 0, the process advances to step S21, the rotation of the paper feed motor 103 is stopped, and the cutter 2 is stopped.
25, the thermal paper 222 is cut into a predetermined size, and the process is completed.

On the other hand, if it is determined in step S14 that copy processing is to be performed, the process proceeds to step S24, and in the same manner as step 316, it is determined based on the signal from the sensor 223 whether or not there is thermal paper 222. If there is thermal paper 222, the process advances to step S26, where the paper feed motor 103 is rotated counterclockwise by a predetermined amount to convey the sheet original to the reading position by the reading sensor 111, and the contact sensor 105 is lowered to read the original. conduct. In step S27, the paper feed motor 10
3 is stopped in the counterclockwise direction, and step S28
The paper feed motor 103 is reversed several steps clockwise. This is to correct the backlash of the gear 230 and the gear 208, which are then rotationally driven to transport the thermal paper 222.

That is, as shown in FIG. 8, after the paper feed motor 103 (gear 208) is rotated counterclockwise to transfer the sheet document, when the gear 208 is rotated clockwise by a predetermined amount, the gear “Play” between 208 and gear 230,
and a spring clutch 7 between gear 230 and gear 230-1.
11, the paper feed motor 103
The clockwise rotation of the thermal paper 222 is not directly transmitted to the gear 228, and the thermal paper 222 is not transferred by a predetermined amount.

To prevent this, in step 528, the paper feed motor 103 is reversed several steps clockwise, and the gear 2
The displacement of gear 208 and gear 230 is adjusted so that the clockwise rotation of gear 208 is directly transmitted to gear 230-1. Such adjustment also needs to be performed when switching from transporting the thermal paper 222 to transporting a sheet original (when changing the rotation of the paper feed motor 103 from clockwise to counterclockwise) (step 531).

Next, in step S29, the paper feed motor 103 is rotated clockwise to transport the thermal paper 222 by a predetermined amount, and the image information read in step S26 is recorded on the thermal line head 113 on the thermal paper 222. In step S30, the rotation of the paper feed motor 103 is stopped, and in step S31, the paper feed motor 103 is reversed several steps counterclockwise to correct the backlash of the gears 208 and 209.

After this, it is checked in step S32 whether the copying is completed,
If it has not been completed, the process advances to step 333, where the paper feed motor 103 is rotated counterclockwise by a predetermined amount, the sheet original is transferred by a predetermined amount, and the process returns to step S24, where the next line of the original is read and the thermal Recording is performed on paper 222. When copying is completed in step S32, step S34
Then, the thermal paper 222 is cut to a predetermined length by the cutter 225, and the process is completed.

Note that a switch or the like is provided to specify the amount of backlash adjustment in step S28 and step S31 described above.
In steps 328 and 31 of the control program, the setting value of this switch may be read to determine the amount of reversal of the paper feed motor 103. By doing this, the "play amount" between the gear 208 and the gear 209 or the gear 230 changes due to wear of the gear, for example, and a deviation occurs in the feeding amount of the thermal paper or the feeding amount of the sheet. Adjustments can be made even if the

In this example, the selection between serial recording and line recording is as follows:
Although it has been explained that the data is specified at the same time as recording data is input, the present invention is not limited to this, but the settings may be made from the operation panel of the reader printer, or the document data is recorded serially and the dot image data is Alternatively, line recording may be performed.

Further, in this embodiment, the line recording is thermal recording on thermal paper, and the serial recording is recording by a thermal transfer method, but it is needless to say that the present invention is not limited to this.

As explained above, according to this embodiment, it is possible to perform serial recording on a sheet, record in units of lines using the line head, and also read the original and reproduce and record the read original. be able to.

Further, by using the same motor to transport the read sheet original or the sheet used for serial recording and the transport of the recording paper recorded line by line, manufacturing costs can be reduced.

Furthermore, by correcting backlash due to reverse rotation of the paper feed motor, it is possible to correct misalignment of the reading position and misalignment of the recording position, for example, in a copying operation in which an original i is read and recorded.

Note that this sheet includes, for example, plain paper and OHP plastic thin plate.

[Effects of the Invention] As described above, according to the present invention, there is an advantage that serial recording, line-by-line recording, and sheet document reading can be performed using one reading and recording device.
