Conventionally, the hopping roller 32 is driven by the LF motor 7 via a gear train, but the printer with a scanner according to this specific example reversely feeds the medium set on the manual feed table 39 by the LF motor 7. Therefore, a new dedicated H
A P motor 10 is provided.

A simultaneous copy switch 11 is provided on an operation panel (not shown) of the apparatus main body. When the simultaneous copy switch 11 is pressed, the ASIC 1 executes a simultaneous copy control program stored in the ROM 4.

FIG. 3 is an explanatory diagram of the set position of the printing paper and the read original. As shown in FIG. 3, during continuous printing and continuous reading, the medium (print paper, read original) is set on the hopper 31, and during interrupt printing and interrupt reading, the medium is set on the manual feed table 39. You. At the time of simultaneous copying, the printing paper is set on the hopper 31 and the read original is set on the manual feed table 39. In either operation, the printing paper is set with its print side up and the read document is set with its read side down.

<Operation> FIG. 4 is a diagram for explaining the operation of continuous printing / continuous reading. Continuous printing refers to an operation of continuously printing a plurality of pages in a series of operations, and continuous reading refers to an operation of continuously reading a plurality of documents in a series of operations. During continuous printing, the printing paper S is set on the hopper 31 with the printing surface up. When reading continuously, the original R
Is set on the hopper 31 with the reading surface facing down. Note that the manual feed table 39 is stored in a contracted state in the apparatus main body in the vertical direction. The rear guide 45 is held along the bottom surface of the hopper 31.

The operation of continuous printing will be described. When the print command is received, the printing paper S is separated by the hopping roller 32 and fed to the transport path 40. The fed printing paper S is conveyed while being sandwiched between the roller pairs 33a and 33b, and reaches the sensor 36 as shown in FIG.

When the leading end of the printing paper S is detected by the sensor 36, the control of the number of pulses of the LF motor 7 is started, and the printing of the printing paper S is started by the pair of rollers 33a and 33b driven by the LF motor 7. The sheet is fed to the position, and printing is started by the inkjet head 21. Thereafter, as shown in FIG. 4B, the main scanning by the SP motor 6 and the sub-scanning by the LF motor 7 are alternately repeated to perform printing. Further, the printing paper S is conveyed while being held between the pair of rollers 34a and 34b.

As shown in FIG. 4C, when the trailing edge of the printing paper S is detected by the sensor 36, the management of the lower end (bottom margin) of the printing area is started. As shown in FIG. 4D, when printing is completed, the printing paper S is discharged to the discharge stacker 38. Thereafter, the printing of the subsequent pages is similarly repeated.

In continuous printing, when the leading edge of the printing paper is detected by the sensor 36, the operation of the ink jet head 21 is started after a predetermined time. On the other hand, in continuous reading, the leading edge of the document R is detected by the sensor 37. When detected, the operation of the line scanner 23 starts after a predetermined time. Other operations of the continuous reading are the same as those of the continuous printing, and the description thereof will be omitted.

As described above, in the printer with a scanner according to this embodiment, a plurality of originals are set on the hopper 31 and the line scanner 23 provided on the same conveyance path 40 as the printing paper.
By reading the image of the original continuously in a series of operations,
Continuous reading can be performed. Further, since the reading means is constituted by the line scanner 23, the image can be read at high speed.

FIG. 5 is an explanatory diagram of the simultaneous copying operation.
Simultaneous copying refers to an operation of printing the read image on printing paper by the inkjet head 21 while reading the image of the document by the line scanner 23. The printing paper S is set on the hopper 31 with the printing surface up. The document R is set on the manual feed table 39 with the reading surface facing down. Then, when the simultaneous copy switch 11 on the operation panel (not shown) is pressed, the simultaneous copy control program stored in the ROM 4 is started, and the simultaneous copy is performed.

As shown in FIG. 5A, the manual feed table 39 is set so that the original R comes into contact with the pair of rollers 34a and 34b.
When the document R is set on the upper side, the document R is detected by the sensor 37, and the operable state is established. Then, when the simultaneous copy switch 11 is pressed, the roller pair 34a, 34b and the roller pair 33a, 33b rotate in the reverse direction, and the document R set on the manual feed table 39 is nipped by the roller pair 34a, 34b to be transported. It is fed in the opposite direction to 40. Further, as shown in FIG. 5B, the original R is
When the sensor 36 detects the leading end of the document, the leading end of the document is transferred to a pair of rollers 33a.
It stops while being pinched by 33b.

As shown in FIG. 5C, the roller pair 33
a, 33b and the pair of rollers 34a, 34b rotate forward, the original R is conveyed in the forward direction, and the printing paper S is separated by the hopping roller 32.
The document R is fed between the document R sandwiched by 3b and the roller pair 33a. As shown in FIG. 5D, the printing paper S is inserted between the document R and the roller pair 33a and overlaps the document R, and together with the document R, the roller pairs 33a and 33b and the roller pairs 34a and 34b. And transported in the forward direction.

When the document R reaches the sensor 37, reading of the image of the document R by the line scanner 23 is started.
At the same time, the image read by the line scanner 23 is sent to the inkjet head 21, and after a predetermined time, printing on the printing paper S is started by the inkjet head 21. As shown in FIG. 5D, the document R and the printing paper S are conveyed while being superimposed on each other, and the image of the document R read by the line scanner 23 is printed on the printing paper S by the inkjet head 21. And
The document R and the printing paper S are discharged to the manual feed table 39.

The distance between the leading edge of the document R and the leading edge of the printing paper S depends on the timing at which the document R is transported in the forward direction by the pair of rollers 33a and 33b which have been stopped, and the time when the printing paper S is transported by the hopping roller 32. It is determined by the timing of feeding. This distance needs to be larger than the distance L between the reading position of the line scanner 23 and the printing position of the inkjet head 21. Printing paper S and original R
Are conveyed in a superimposed manner because the distance between the inkjet head 21 and the line scanner 23 is short. If this distance is increased, the transport path 40 will be longer, and the device will be larger.

As described above, in the printer with a scanner according to this embodiment, the line scanner 23 is provided in the transport path 40 on the side opposite to the non-printing surface of the printing paper transported through the transport path 40 provided with the ink jet head 21. The original R is fed to the non-printing side of the printing paper S fed from the hopper 31 to the transport path 40 by the hopping roller 32.
Then, the printing paper S and the document R fed to the transport path 40 are nipped and transported by the roller pairs 33a and 33b and the roller pairs 34a and 34b while being overlapped, and simultaneous copying is performed. For this reason, it is possible to provide a printer with a scanner of a shared transport path that can perform simultaneous copying using a transport path shared by the printing paper and the original for reading.

Also, a manual feed table 39 is provided at the exit side of the transport path 40, which is the front side of the apparatus.
Is transported backward from the exit side to the entrance side of the transport path 40 by the roller pairs 34a and 34b and the roller pairs 33a and 33b. Further, the printing paper S and the original R on which the simultaneous copying has been performed are stored in the manual feed table 39.
Is discharged. Therefore, there is an effect that the document R can be easily set and the printing paper S and the document R can be easily taken out from the printer.

Since the document R is conveyed in the forward direction of the conveyance path 40 while being superposed on the printing paper S fed from the hopper 31, it is necessary to set the document R at a position different from that of the hopper 31. For example, the original R is placed on the roller guide 3 from the rear guide 45 side.
4a, 34b may be set so as to be in contact with them. In this case, since the setting is difficult to be performed due to the presence of the hopper 31, it is preferable to use the rear guide 45 by tilting it.

FIG. 6 is a diagram for explaining the operation of duplex printing. Double-sided printing is an operation in which a sheet on which an image is printed on a non-printing side is prepared in advance, an image on the non-printing side of the sheet is read, and information obtained from the read image is printed on the printing side of the printing sheet. Say. The image read by the scanner of the printer is transmitted to the host device. The host device recognizes information from the received image and transmits information (print data) corresponding to the recognized information to the printer. The printer prints information received from the host device.

The double-sided printing is used, for example, when recording a hospital visit history in a ledger (personal information card). Since this ledger is used repeatedly, thick paper is used. On one side of the sheet, identification information for identifying an individual is printed in advance. On the other side of the sheet, the visit history of the corresponding individual is recorded each time or periodically. In duplex printing, the surface on which personal identification information is recorded is the non-printing surface (reading surface), and the surface on which the visit history is recorded is the printing surface.

As another example, it is used for a concealed postcard, for example. The address is printed on one side of the postcard in advance.
On the other side of the postcard, personal information corresponding to the address is printed. Then, this personal information is covered so as not to be seen by others during mailing. In duplex printing, the surface on which the address is printed is the non-printing surface (reading surface), and the surface on which personal information is printed is the printing surface.

The operation will be described below. As shown in FIG. 6A, the thick paper Q is set on the manual feed table 39 with the printing surface up and the non-printing surface (reading surface) down so as to contact the roller pair 34a, 34b. You. The rear guide 45 is held horizontally so as to be linear with the guides 41 and 42.

Roller pair 34a, 34b and roller pair 3
3a and 33b are reversed, and the sheet Q set on the manual feed table 39 is nipped by the pair of rollers 34a and 34b.
The paper is fed to the conveyance path 40 in the reverse direction. Further, FIG.
As shown in the figure, the paper Q is a pair of reversing rollers 33a, 3
When the sensor 36 detects the leading end of the document, the leading end of the document is transferred to a pair of rollers 33a.
It stops while being pinched by 33b.

At this time, the image on the reading surface of the sheet passing through the reading position is read by the line scanner 23, and the read image is transmitted to the host device. The host device recognizes information from the transmitted image and searches for information corresponding to the recognized information from the stored information. Then, the searched information is transmitted to the printer as print data.

When the printer receives the print data from the host device, as shown in FIG. 6C, the roller pairs 33a and 33b and the roller pairs 34a and 34b rotate normally, and the paper Q is transferred to the roller pairs 33a and 33b and Roller pair 3
4a and 34b, the paper Q is conveyed in the forward direction, and printing is performed on the printing surface of the paper Q by the inkjet head 21. Then, as shown in FIG. 6D, the paper Q is discharged onto the manual feed table 39.

As described above, according to the printer with a scanner of this embodiment, in addition to high-speed reading, continuous reading, and simultaneous copying, double-sided printing can be performed. Also in this example, the paper is set on the manual feed table 39. For this reason, there is an effect that the paper Q can be easily set and the paper Q can be easily taken out from the printer.

FIG. 7 is a diagram for explaining the operation of interruption printing / interruption reading. Interrupt printing refers to an operation of printing another print data during continuous printing and continuous reading. The print paper S for interrupt printing is set on the manual feed table 39 with the print surface facing up. Interrupt reading refers to an operation of reading an image of another document during continuous printing and continuous reading. The document R for interrupt reading is set on the manual feed table 39 with the reading surface facing down. In this printer, since the operation is managed on a page basis, printing is being performed by the inkjet head 21 or the line scanner 2
In the case where the reading operation is being performed according to step 3, the interruption is performed after the operation of the page is completed.

The operation of the interrupt printing will be described. Printing paper S
Is set on the manual feed table 39 with the printing surface up so as to contact the roller pair 34a, 34b. The printing paper S is nipped by the pair of rollers 34a and 34b that rotate in the reverse direction, and is fed to the transport path 40 in the reverse direction. Further, FIG.
As shown in (b), the printing paper S is nipped by the pair of rollers 33a and 33b that rotate in the reverse direction, and is fed back.
When the leading end of the printing paper S is detected by the above, the leading end of the printing paper S stops while being held between the pair of rollers 33a and 33b.

As shown in FIG. 7C, the roller pair 33
a, 33b and the roller pair 34a, 34b rotate forward, and the printing paper S is moved to the roller pair 33a, 33b and the roller pair 34.
a and 34b are conveyed in the forward direction and printed by the inkjet head 21 on the printing surface of the printing paper S. Then, as shown in FIG.
Is discharged onto the manual feed table 39.

At the time of interrupt printing, as shown in FIG. 7B, the printing paper S set on the manual feed table 39 is used.
Until the sensor 36 detects the leading edge of the printing paper S, the roller pairs 33a and 33b and the roller pairs 34a and 3a
4b. On the other hand, at the time of the interruption reading, as shown in FIG. 7B ', the document R set on the manual feed table 39 keeps the roller pair 33a, 33b until the leading end of the document R is detected by the sensor 37. And the roller pair 34a, 34b. Other operations of the interrupt reading are the same as those of the interrupt printing, and the description thereof will be omitted.

As described above, according to the printer with a scanner of this specific example, it is possible to further perform interrupt printing and interrupt reading. In the conventional apparatus, the interrupting medium is a hopper 3
It is set and fed to a feeder separately provided above or below 1. For this reason, attention must be paid to the structural arrangement between the hopper 31 and the feeder for interruption. On the other hand, according to the printer with a scanner of this specific example, an interruption medium (print paper S, original R) is set on the manual feed table 39. For this reason, the hopper 3
1 is simplified, the medium can be easily set, and the medium can be easily removed from the printer.

<Effects> FIG. 8 is a diagram illustrating a comparison between the apparatus of the present invention and the conventional apparatus. As shown in FIG. 8, in the conventional apparatus independent of the transport path, high-speed reading and simultaneous copying can be performed, but continuous reading cannot be performed. Further, in the conventional apparatus using a common transport path, continuous reading can be performed, but high-speed reading and simultaneous copying cannot be performed. Furthermore, both conventional apparatuses could not perform duplex printing. On the other hand, according to the printer with a scanner of the present invention, high-speed reading, continuous reading, simultaneous copying, double-sided printing can be performed, and interrupt printing and interrupt reading can also be performed.

A manual feed table 39 is provided at the exit side of the transport path 40, which is the front side of the apparatus. The manual feed table 3 is used for simultaneous copying, double-sided printing, interrupt printing, and interrupt reading.
The medium is set in 9, and the medium is carried out to the manual feed table 39. For this reason, it is easy to set and take out the medium. Further, structurally, since the manual feed table 39 and the rear guide 45 are added to the conventional apparatus common to the conveyance path, the apparatus does not become expensive. Therefore, a multifunctional and inexpensive printer with a scanner can be provided. It should be noted that the printing method is not limited to the ink jet printing method, and may be, for example, a thermal transfer method or an electrophotographic method.
