Abstract

PURPOSE:To minimize a size of a recording device and improve operability by using the discharging port of a sheet paper fed from a primary sheet feed port of the secondary sheet feed means, and constituting the same sheet paper feed port as a discharging port for discharging sheet paper after printing. CONSTITUTION:A sheet paper 3 fed from a cassette 22 which is a primary sheet feed means is led to a sub-scan loller 7 by a sheet feed roller 21. Printing is carried out on a printed part 8 by a print head 9, and is discharged to a sheet discharging tray 24 through a sheet discharging port by a sheet discharging roller 10. When a plunger 20 is energized, a manual guide plate 24a rises. If a sheet paper 18 is inserted along the guide plate 24a, the top part 18a of the sheet paper 18 hits a nip of the sheet discharging roller 10 to press a sheet detection lever 29. Since the lever 27 is pressed, the sheet discharging roller 10 and the sub-scan roller 7 rotate in the reverse direction to the usual one, and the inserted sheet paper 18 is fed into a recording device.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recording device, and more particularly, to a paper feeding device for a recording device such as a copying machine or a printer, in which at least two systems of paper feeding can be selected.

[Conventional technology]

FIG. 12 shows a conventional example of a recording apparatus having two or more (two systems) paper feeding means.

In FIG. 12, paper feed roller 1 which is the first paper feed means
As a result, the paper 3 loaded in the cassette 2 is separated by the separation claw 4.
The sheets are separated one by one by the paper guide 5 and conveyed to a conveyance roller 6 installed in the middle of the paper guide 5. The paper is further transported to the sub-scanning roller 7 by the transport roller 6, and then transferred to the printing section 8.
The print width is conveyed to the print width. The print head 9 is moved in the width direction of the paper by guide I knobs 19a and 19b, and prints on the paper at the print unit 8 by ejecting droplets. The printed paper is delivered to a discharge port 11 by a paper discharge roller 10.
The paper is then discharged onto the paper discharge tray 12.

On the other hand, the second paper feed means is a so-called manual paper feed, in which a sheet of paper is placed on the manual feed I-1 noi 13, and the sheet is placed in the manual feed slot 1.
4, and is conveyed to the sub-scanning roller 7 by a manual feed roller 15, passing through a paper guide plate 14. From the sub-scanning roller 7 onward, printing is performed on the paper in the same manner as for paper fed from the cassette 2, and the paper is discharged from the paper discharge port 11 onto the paper discharge tray 12 by the paper discharge roller 10.

Further, the aforementioned cassette 2 can be pulled out in the direction of arrow A in the figure, and sheets 3 can be replenished.

[Problems to be solved by the invention] In the above conventional example, as shown in FIG.
Handling the paper after printing is done from the left side, and conversely, when manually feeding paper, it is handled from the right side. Therefore, in addition to the installation location of the machine body, space for the operator is required on the left and right sides, resulting in the disadvantage that the machine cannot be operated unless there is a large installation space.

In addition, in the case of this type of device, it is customary to install the operation section on the front side of the device on the side where the printed paper is ejected (the left side in the figure), but it is not recommended to use the entire device by storing it on a shelf or the like. manual paper feed tray 13 or manual paper feed slot 14.
There is also the problem that it cannot be used at all because it is hidden at the back of the shelf.

[Means for Solving the Problems (and Effects)] In order to solve the above-mentioned problems, the present invention connects the ejection port of the paper fed from the main paper feeding means to the paper feeding port of the second paper feeding means. In addition, after printing, the paper can be ejected again using the same paper feed port as an ejection port. This allows all paper feeding and ejection to be performed from one side of the recording apparatus.

〔Example〕

FIG. 1 shows a sectional view of an embodiment of the present invention. In this figure, the left side is the front side of this recording device. This figure shows the state when paper is fed from the cassette 22, which is the first paper feeding means. The paper conveyance guide section 23 includes paper feed guides 23a and 23b.
The cassette 2 is configured by the paper feed roller 21.
The paper 3 fed from the paper 2 is guided to the sub-scanning roller rough. In the printing section 8, a print head 9 that is movable in the width direction of the paper by guide rails 19a and 19b ejects droplets to print on the paper.

This ink cartridge (print head) 9 is a head 9a.
The ink tank and the ink tank are integrated, and it is disposable and can be replaced. The head 9a is provided with a plurality of liquid paths filled with liquid (ink). In a steady state, the surface tension and external pressure of the ink filled in these liquid channels are balanced on the orifice surface. Electrothermal converters are arranged in each of the plurality of liquid paths, and by applying at least one drive signal to these electrothermal converters to cause a rapid temperature rise beyond nucleate boiling. Thermal energy is generated to vaporize adjacent ink and cause film boiling. As a result, bubbles corresponding to the drive signal are formed in the ink, and as the bubbles grow, the ink is ejected from the orifice surface onto the recording medium 3. Further, the bubbles are cooled by the ink and contracted, and ink is sequentially supplied from the ink tank into the liquid path by capillary action.

As described above, by growing or contracting bubbles in the liquid path filled with ink, ink can be ejected from the orifice surface to form a single droplet. Therefore, when a driving signal is applied in a pulse shape to the electrothermal transducer according to the image information, the bubbles grow and contract instantly, and the ink is ejected from the orifice surface of the head 9a onto the recording medium 3. Recording can be done.

Then, the printed recording paper is discharged from the paper discharge port 11 to the paper discharge tray 24 by the paper discharge roller 10. Cassette 2
2 can be pulled out in the direction of arrow B in the figure to set the paper 3.

FIGS. 2 and 3 show an overall view of the manual paper feed, which is the second paper feed means, and FIG. 4 shows a detailed view thereof.

In FIG. 4, the manual feed guide plate 24a is swingably attached to the paper discharge tray 24 by a hinge 24b. At its tip, there is a hinge 24c outside the paper passing area.
It is engaged with the plunger 2o. By energizing the plunger 2o, the manual feed guide plate 24a rises to a position where its tip faces the nip of the paper ejection roller 1o, as shown in FIG. Return to the original position.

A lever 29 for detecting the presence or absence of paper is attached to a stepped portion 25 provided within the paper passing area of the paper ejection roller 10 so as to be able to swing around a hinge 23, and has an arcuate portion 29a lower than the nip position of the paper ejection roller. (Due to balance with spring SP). Therefore, regardless of whether the paper comes from the left or right in the figure, if the paper is caught in the nip of the paper ejection roller 10, the detection lever 29
swings down and cuts off the photo sensor (not shown),
A paper presence signal can be generated.

FIG. 2 shows the paper 18 set for manual paper feeding. By pressing the manual feed switch SWI, the electric system is switched from the cassette paper feeding mode to the manual feeding mode, and at the same time the plunger 20 is activated. is excited,
The manual feed guide plate 24a rises to the above-mentioned position. Next, if the operator inserts the paper along this guide plate,
The leading edge 18a of the paper hits the nip of the paper ejection roller 10,
Press the paper detection lever 29. When the lever 29 is pressed, an electric signal is input by the photosensor (FT), the paper ejection roller 10 and the sub-scanning roller 7 rotate to the left in the opposite direction to the normal case, and the inserted paper 18 is fed into the recording device. . The leading edge 18a of the fed paper is guided between the paper feed roller 21 and the uppermost paper in the cassette 22 by a guide plate 23b.

FIG. 3 shows a state in which the fed paper is temporarily stopped within the recording apparatus. The stop position is at the trailing edge 18b of the paper.
reaches the right side of the printing unit 8 after passing through the paper detection lever 29 in FIG. Specifically, the count is started after the trailing edge of the paper passes through the lever 29.
The rollers are stopped after a predetermined count. From the state shown in FIG. 3, if the sub-scanning roller 7 and the paper ejection roller 10 are rotated forward (rotated to the right) again in response to the paper feeding start (printing start) signal and at the same time the plunger 20 is de-energized, the manual feed guide 24a
returns to the state shown in FIG. 1, and the manually fed paper 18 is printed and discharged in exactly the same state as when it is fed from the cassette 22.

To manually feed paper continuously, remove the ejected paper and press the manual feed switch again. Further, if paper is to be fed from the cassette after the manually fed paper is ejected, the normal printing operation can be performed as is.

With the above configuration, if the operation panel is installed on the paper output side, cassette paper feeding, cassette insertion/removal, manual paper feeding, and paper ejection can all be performed from the left side of Figure 1. It can also be used with the entire unit stored on a shelf.

In addition, the paper is fed by rotating the paper ejection roller and the paper transport rollers such as the sub-scanning roller in the opposite direction, so a dedicated paper feed roller or Since there is no need to provide a conveyance roller and the number of conveyance guide plates and the like can be minimized, it is possible to downsize and reduce costs of the recording apparatus.

In the state shown in FIG. 3, the trailing edge 18b of the paper may be stopped when it coincides with the printing position P0 (this has the effect of allowing immediate printing), or it may be stopped immediately after passing through the rollers 10 ( (The effect is that the sheet is stretched during printing.) This positioning of the paper is performed by counting pulses after the trailing edge of the paper passes through the paper ejection roller 10.

[Other Examples]

(i) In this embodiment, the manual feed guide plate 24a is swung with respect to the paper ejection tray 24 to serve as both the paper ejection tray and the manual feed tray, making it more compact. The same effect can be obtained even if the manual feed tray 30 is fixed and installed on the tray 24 in advance. The tip of the manual tray 30 faces the nip portion of the roller 10. Further, the manual tray 30 has a guide portion that guides the paper discharged from the roller 10 to the tray 24.

(ii) In this embodiment, the manual feed guide plate 24a
Although the manual feed guide plate is displaced by the plunger 20, it is also possible to vertically swing the manual feed guide plate by rotating the paper discharge roller in the forward and reverse directions via a gear, clutch, or the like. FIG. 6 shows an example of this embodiment, in which the manual feed guide 42a is raised and a manual paper feed port 48 is formed. The arc-shaped gear 42c meshes with a gear 46 attached to the shaft end 10a of the paper discharge roller 10 via an electromagnetic clutch 47. In addition, the gear 46 is
By energizing the electromagnetic clutch 47, it rotates together with the paper ejection roller 10. 42e is an escape hole.

With the above configuration, when a paper feed button (not shown) is pressed to feed paper, the electromagnetic clutch 47 is energized and the paper ejection roller 10 is rotated clockwise in the figure. Since the arc gear 46 rotates together with the paper ejection roller 10, rotate the arc gear 42C to move the paper feed guide plate 42a to the position shown in the figure.
can be raised. After the manual feed guide plate 42a has risen to the position shown in the figure (by timer up or detection by the position detection means), if the rotation of the paper discharge roller 10 is stopped, the manual feed guide plate 42a will stop at the position shown in the figure. Until the electromagnetic clutch 47 is de-energized, the manual feed guide plate 42a is held by the frictional force of the drive system such as the paper ejection roller shaft.

After that, when the paper is inserted from the paper feed port 48, the electromagnetic clutch 47 is de-energized and the paper discharge roller 10 is rotated clockwise again, and the paper is fed into the main unit in the same manner as in the above-described embodiment. be done.

During paper ejection, the paper ejection roller 10 rotates counterclockwise, so if the electromagnetic clutch 47 is energized again for a certain period of time, the gear 4
6 also rotates counterclockwise, the manual feed guide plate 42a also descends, and a paper ejection port is formed again in the same manner as in the embodiment described above.

After the manual feed guide plate 42a is completely lowered, if the electromagnetic clutch 47 is de-energized, the paper is ejected onto the paper ejection tray 42 without any problem.

(iii) In this embodiment, a recording device that prints by ejecting droplets has been described, but it goes without saying that any printing method may be used.

(iv) Although cassette paper feeding is presented as the first paper feeding means, other paper feeding means may also be used.
Further, it is also applicable even if there are three or more paper feeding means.

(v) Although we have presented a manual paper feed system in which paper is inserted one sheet at a time as a second paper feeding means, it is also possible to use a small two-stage cassette machine as a cassette paper feeder, as shown in Figure 7. . Similarly, multiple manual paper feeding is also possible. In FIG. 7, the paper feed cassette 50 is supported by the recording apparatus by a paper feed guide member 51 and a cassette receiver 52, and is fixed by being caught on the cassette receiver 52 by a pull-out stopper 51a. Paper 3 loaded in the cassette
3 are separated one by one from the uppermost paper by the paper feed roller 54 and the cassette separation claw 55, and are sent to the paper discharge roller 10 by the guide plate 56. At this time, as described in the first embodiment, if the paper discharge roller 10 is rotated in the direction in which the paper is fed into the recording apparatus, the paper is conveyed into the apparatus.

Hereinafter, the paper printed in the same process as explained in the first embodiment is guided by the inclined guide part 51a and placed on the paper output tray 6.
2.

(vi) As shown in FIG. 11, an elastic Mylar material is placed in the bus between the paper feed roller 21 and the roller 7, and the end of the sheet inserted from the left side is placed in the dedicated bus (guide 71.
72).

(vii) When inserting the sheet from the left side (FIG. 11), the rotation of the roller 10.7 is stopped when the trailing edge of the sheet is detected by the sensor S2, and then the rotation of the roller 10.7 is stopped. 7 may be reversed to feed the sheet to the left and start printing.

According to the configuration of the above embodiment of the present invention, the paper ejection port fed from the first paper feeding means can be used as the paper feeding port of the second paper feeding means, so that the paper ejection port can be used as the paper feeding port of the second paper feeding means. If the opening is placed at the front of the device, the cassette paper feed, manual paper feed, paper ejection tray, etc. can all be provided on the front side. Therefore, since the recording device can be handled entirely from the front, the entire device can be used while being stored on a shelf, making it possible to save space during installation.

In addition, there is no need to provide a dedicated paper feed roller or transport roller for auxiliary paper feeding means such as manual paper feeding.
In addition, the number of conveyance guide plates and the like can be minimized, and the manual paper feed tray and paper ejection tray can also be used, making it possible to downsize the recording apparatus and reduce costs.

Next, we will explain in detail how to prevent the recording sheet from floating, which can reliably prevent the recording sheet from floating, etc., without adversely affecting sheet conveyance.

FIG. 12 is an explanatory diagram of the configuration of a recording apparatus equipped with a lifting prevention device.

This recording device is configured such that a recording sheet (paper) supplied from the sheet supply device is conveyed by a conveyance means (sub-scanning roller) 7, and a predetermined image is recorded by a recording means (print head) 9. The recording sheet 3 is configured to be pressed down by a sheet pressing member 104 during the recording.

The sheet conveying means 7 is composed of a first pair of conveying rollers 71 and 72 and a second pair of conveying rollers (discharge rollers) 10 and 102, and the first conveying rollers 7. and second conveyance roller 10. is configured to rotate and convey the recording sheet 3 in the direction of arrow a.

The second conveying rollers io, , io are configured so that rotational force is transmitted to them via a slipping clutch (not shown) to apply appropriate tension to the recording sheet 3 being conveyed.

The recording means 9 has an inkjet recording head 9a.
and a platen 103b are arranged to face each other, and the recording head 9a is mounted on a carriage 9c. The carriage 9c is configured to be able to reciprocate in the directions of arrows A and C along guide shafts 9a and 9b of a carriage motor and drive transmission system (not shown), and during this movement, the recording head 9
A predetermined image is recorded on the recording sheet 1 by ejecting ink from a in accordance with an image signal. Incidentally, a home position sensor 103 is installed at the home position of the carriage 9c to detect this.
e is arranged.

Further, the sheet holding member 104 is a holding part 104 on the plate.
a and arm portions 104b formed at both ends thereof, and this arm portion 104b serves as the rotating shaft 7.a of the first conveyance roller 72. is rotatably attached to. A tension spring 104C is attached to the presser portion 104a, so that the presser portion 104a presses the recording sheet 3 against the platen 103b.

The sheet pressing member 104 is configured to be able to come into contact with and separate from the recording sheet 3 by a contacting and separating means, and in this embodiment, a solenoid 105 is used as the contacting and separating means. That is, the solenoid 1 is installed at the end of the arm portion 104b.
05 is attached and this solenoid 105 is turned on, the arm portion 104b rotates in the direction of arrow d, and the holding portion 1
04a is separated from the recording sheet 3. On the other hand, when the solenoid 105 is turned off, the holding portion 104a
04C pulls the recording sheet 3 onto the platen 1.
03b. The left side of the holding member 104 in FIG. 1 is configured to slant downward to the right.

The sheet pressing member 104 is turned on and off in accordance with the conveyance and recording operation of the recording sheet 3, and the control system therefor is constructed as shown in the block diagram of FIG. 13.

That is, the CPU 106a1 such as a microprocessor
Image signals are sent via an interface 107 to a control unit 106 equipped with a ROM 106b that stores control programs and various data for the U 106a, and a RAM 106C that is used as a work area for the CPU 106a and temporarily stores various data. An input device 108 and a home position sensor 103e are connected, from which an image signal and a detection signal indicating whether the carriage 9C is at the home position are input.

Further, the control unit 106 is connected to a motor driver 109 and a head driver 11 via an interface 107.
0 and solenoid driver 111 are connected respectively. Then, in response to a signal from the control unit 106, the motor driver 109 drives a carriage motor 112 for moving the carriage 9C and a sheet conveyance motor 113 for driving the conveyance rollers 71 and 10, and the head driver 110 operates according to the image signal. recording head 9a
The solenoid driver 111 drives the solenoid 105.

Next, the operation procedure of the sheet pressing member 104 and the like when recording is performed by the recording apparatus configured as described above will be explained with reference to the flowchart of FIG.

First, when an image signal is input from the image signal input device 108, the solenoid 105 turns off (Sl, S2), and the spring 1
The sheet pressing member 104 presses the recording sheet 3 against the platen by the urging force of 04C.

Next, the carriage motor 112 rotates forward to move the carriage 9C in the direction of the arrow in FIG.
The recording head 9a ejects ink according to the image signal to record an image on the recording sheet 3 (83, S4).

When one line recording is completed as described above (S5), the carriage motor 112 is driven in reverse to move the carriage 9C to the first position.
Move the carriage 9c in the direction of arrow C in Figure 2 (S6).
When the carriage motor 112 returns to the home position (S7), the carriage motor 112 stops driving (S8).

Next, if there is no recording on the next line, the recording operation ends, but if there is recording on the next line, the solenoid 105 is turned on, and the sheet pressing member 104 rotates in the direction of the arrow d in the twelfth column, thereby pressing the recording sheet 1. (89, S10) In this state, the conveyance motor 113 rotates by a predetermined amount to convey the recording sheet 3 by one line in the direction of arrow a in FIG.
513), returns to step S2 and repeats the same procedure as above.

As described above, when recording an image, the sheet pressing member 104 presses the recording sheet 3 against the platen 103b to eliminate sagging or floating of the recording sheet 3 and record a high-quality image, and when conveying the sheet, the sheet pressing member 10
By separating the recording sheet 4 from the recording sheet 3, the sheet conveyance load is reduced and conveyance accuracy is improved.

[Other examples of anti-lifting devices]

In the first embodiment described above, an example was shown in which the sheet pressing member 104 is moved by the solenoid 105, but as a second embodiment, FIG. 15 shows an example in which the sheet pressing member 204 is moved by scanning the carriage 209c. . Incidentally, the same parts as in the first embodiment are given the same reference numerals and the explanation will be omitted.

A tension spring 204d is attached to the end of the τ-arm portion 204b of the sheet holding member 204, and the holding portion 204
a is urged away from the recording sheet 3. A gentle slope portion 204e is provided at the end of the holding portion 204a (home position side of the carriage 209C), and a rotatable roller 209e is provided at the bottom of the carriage 209C.
and configure it.

In the above configuration, the carriage 2 is operated according to the recording operation procedure (811 to 521) shown in the flow chart of FIG.
When 09C moves, the sheet pressing member 204 contacts and separates from the recording sheet 3. That is, when the carriage 209C is at the home position, the pressing part 204a is separated from the recording sheet 3 by the bias of the spring 204d, and when the carriage 209C moves in the direction indicated by the arrow during recording, the roller 203e rides on the gentle slope part 204e. , the sheet pressing member 204 is rotated in the direction of arrow e, and as shown in FIG. 17, the pressing portion 204a is moved without being pressed against the recording sheet 3 by the weight of the carriage 209C. Then, when the carriage 209C returns to the home position and the roller 203e comes off the gentle slope section 204e, the holding section 204a separates from the recording sheet 3 again.

Therefore, in this embodiment, the recording sheet 3 is moved to the platen 1 during recording without using a moving means such as a solenoid.
03b, separated from the recording sheet 3 during conveyance,
In addition, the sheet 3 recorded by the recording head 209a can be reliably pressed against the platen 103b.

In the above-mentioned embodiment, an example was shown in which a roller was used as the conveyance means, but this need not be limited to a roller-like one, and any means that can convey the recording sheet 3 may be used (for example, a rotating belt, etc.). It may be something like this.

Next, the operations of manual paper feeding, cassette feeding, and paper feeding will be explained in detail.

(i) When paper is fed from a cassette In FIG. 18, paper 3 fed from the cassette 22
comes into contact with the registration roller 7 and stops. after that,
The first transport roller (registration roller) 7 responds to the print command.
It is sent to the printing position. At this time, carriage 2
09C is waiting at a home position outside the paper passing area as shown in FIG. After a predetermined pulse after the registration roller 7 starts rotating (after the leading edge of the sheet reaches the printing position), the carriage 209C scans along the rail 103d and prints one line. The roller 209e rides on the paper press plate 204, and the paper press plate 204 is brought into pressure contact with the paper.

FIG. 17 is a cross-sectional view showing this state, and it is possible to prevent the paper from floating up to the vicinity of the printing section by using the paper pressing plate. ■
Even if the paper thickness changes, the head follows through the rollers, so the distance between the head and the paper can be kept constant. ■Even if the roller gets dirty with ink, it won't stain the paper because it doesn't touch the paper directly. ■Paper feeding for printing the next line is performed after the carriage has returned to the home position and the paper presser plate has been retracted, so no extra load is applied to the paper, so paper feeding accuracy can be maintained. There are other effects.

When the printing operation and paper feeding operation are repeated a predetermined number of times and printing on the entire area of the paper is completed, the paper is discharged onto the tray with the manual feed guide lowered.

In the embodiment described above (FIG. 18), the paper may be fed until it reaches the second conveyance roller (discharge roller) 10 in response to a print command. In this case, the print head then operates to start printing. The time to start printing is
After a predetermined pulse after the registration roller 7 starts rotating (
(after the sheet reaches the roller 10).

(ii) During manual feeding In FIG. 19, the manual feeding guide 24a on the tray swings in conjunction with a manual feeding button (not shown) and is held at the position shown. When the paper is inserted along this manual feed guide, the conveyance roller 10 starts rotating in reverse, and the paper 3. into the main body.

FIG. 20 is a diagram showing the vicinity of the platen, and since the carriage is stopped at the home position described above when the conveyance roller 10 is reversed, the paper pressing plate 204 is held at a position retracted from the platen. In this embodiment, the paper pressing plate 204 is the first conveying upper roller shaft 7. Since the tip portion 204a+ is configured to rotate around the center, the tip portion 204a+ is held high in this state. As a result, even if the leading edge of the paper 3 a + is curled, it is guided by the paper pressing plate 204 and can be smoothly guided to the nip portion of the first conveying roller.

After the paper is further fed and reaches a predetermined position as shown in FIG. 21, the conveying roller 7 rotates normally and starts fixed-quantity step feeding. Since the carriage does not reciprocate every step (the paper press plate 204 is pushed down by the carriage roller and presses the paper), the printing operation is the same as described above, and will therefore be omitted.

In addition, the manual feed guide 24a returns to the lowered state via the plunger 20 by normal rotation of the roller 7.10 (printing start signal), and after printing is completed, the manual feed guide 24a is moved onto the tray 24 in the same way as when feeding paper from a cassette. be discharged.

According to the configuration of the embodiment of the present invention described above (according to Figures 19 to 21), the outlet for paper fed from the first paper feeder can be used as the paper feeder for the second paper feeder. By doing this, if the paper ejection port is placed at the front of the device, the cassette paper feed,
Manual paper feed, paper ejection tray, etc. can all be installed on the front side. Therefore, since the recording device can be handled entirely from the front, the entire device can be used while being stored on a shelf, making it possible to save space during installation.

In addition, there is no need to provide a dedicated paper feed roller or transport roller for auxiliary paper feeding means such as manual paper feeding.
In addition, the number of conveyance guide plates and the like can be minimized, and the manual paper feed tray and paper ejection tray can also be used, making it possible to downsize the recording apparatus and reduce costs.

〔Effect of the invention〕

Since the feeding device of the recording apparatus according to the present invention has the above-described configuration, it can serve as both the paper ejection port and the paper feeding port, thereby making it possible to downsize the device.

Furthermore, since the paper feed port and the paper discharge port are located on the same side, there is an effect that operability is improved.

Furthermore, by making the sheet pressing member capable of contacting and separating from the recording sheet, the sheet pressing member can be brought into contact with the recording sheet during recording to prevent the sheet from floating, and when the sheet is conveyed, the sheet pressing member can be brought into contact with the recording sheet to prevent the sheet from floating. By separating the member from the sheet, it is possible to prevent adverse effects on conveyance accuracy.

Furthermore, by bringing the sheet pressing member into contact with and separating from it by scanning the recording means, the structure can be simplified and the sheet presser member can be brought into contact with and separated from the recording sheet during recording and sheet conveyance. This is something that can be done.
