2. Description of the Related Art A recording device having a function such as a printer, a copying machine, a facsimile or the like, or a recording device used as an output device of a composite electronic device or a workstation including a computer or a word processor, etc. It is configured to record an image on a recording medium such as a thin plastic plate. Such recording apparatuses can be classified into an ink jet type, a wire dot type, a thermal type, a laser beam type, and the like according to the recording method.

In a serial type printing apparatus employing a serial scan system in which main scanning is performed in a direction intersecting with a conveying direction (sub-scanning direction) of a recording medium, an image is formed by a recording means mounted on a carriage which moves along the recording medium. Is printed (main scanning), a predetermined amount of paper is fed (pitch transport) after printing of one line is completed, and then the image of the next line is printed (main scanning) on the stopped recording medium. ) Is repeated. Thus, image recording is performed on the entire recording medium.

[0004] Among the above recording apparatuses, an ink jet recording apparatus (ink jet recording apparatus) performs recording by discharging ink from a recording means (recording head) onto a recording medium, so that it is easy to make the recording means compact. Thus, a high-definition image can be recorded at a high speed, and can be recorded on plain paper without requiring any special processing.
For this reason, there are advantages such as low running cost, low noise due to the non-impact method, and easy recording of a color image using multicolor inks.

Here, the configuration of the above-described recording apparatus will be described with reference to FIGS. The recording medium loaded on the paper supply unit 502 is supplied to a paper supply roller (FIG.
1 and the like, and are separated and conveyed by a paper feed roller and a pinch roller (36 in FIG. 1, respectively).
37 (equivalent to 37), and further conveyed to a predetermined position by a paper feed roller.

A recording head (corresponding to 7 in FIG. 1) mounted on a carriage (corresponding to 50 in FIG. 1) forms an image on a conveyed recording medium while operating in the main operation direction. The recording medium on which the image is formed is discharged out of the recording apparatus by a discharge roller and a spur (corresponding to 40 and 41 in FIG. 1, respectively). The discharged recording medium is stacked on a paper discharge tray 510.

The paper discharge tray 510 is a main paper discharge tray 54.
4, a first discharge guide 546 and a second discharge guide 547 provided on the left and right sides of the sub discharge tray 545 and the main discharge tray 544.

The paper ejection guides 546 and 547 are rotatably mounted on the main paper ejection tray 544, and are fixed at a position substantially perpendicular to the main paper ejection tray 544. The lower surface of the recording medium discharged outside the apparatus can be guided by these discharge guides 546 and 547. By doing so, the behavior of the discharged recording medium can be suppressed, the change in the gap between the leading end of the recording head and the recording medium can be reduced, and the displacement of ink landing from the recording head can be reduced.

Further, by fixing the paper ejection guides 546 and 547 at a position substantially parallel to the main paper ejection tray 544, the paper ejection guides 546 and 547 are accommodated within substantially the thickness of the main paper ejection tray 544. be able to. By doing so, the size of the paper discharge tray 510 can be reduced, and downsizing and cost reduction can be realized.

Further, the sub-discharge tray 545 is configured to be slidably accommodated in the main discharge tray 544.

The entire discharge tray 510 is slidable along a guide rail 511 provided on a base portion of the apparatus main body. When the apparatus is used, the discharge tray 510 is moved from the apparatus main body. When the paper tray is pulled out and not used, the paper discharge tray 510 is stored in the apparatus main body.

As shown in FIG. 12, a pair of stoppers 512 and 542 are provided on the guide rail 511 and the main discharge tray 544 so that the main discharge tray 544 to be pulled out does not fall out of the guide rail 511. I have.

[0013]

However, the above-mentioned conventional recording apparatus has the following problems.

(1) In recent years, the required resolution of a recorded image has been increased, and it is necessary to further suppress the behavior of the recording medium during image recording. For this reason, it is necessary to hold the discharged recording medium substantially horizontally with respect to the discharge port of the apparatus main body.

In order to achieve this, it is conceivable to enlarge the paper ejection guide so that the paper ejection guide stands up to almost the same height as the ejection opening. However, in this case, the paper ejection guide becomes large. , Cost and size of the entire apparatus (for example, the paper output tray for storing the paper output guide becomes larger)
Disadvantageous in terms of

(2) In a recording apparatus having the same resolution as that of a conventional recording apparatus, the size of the paper discharge tray poses a problem in downsizing the recording apparatus.

(3) Due to the disengagement between the sheet discharge tray and the apparatus main body, it is necessary to increase the fitting length between the sheet discharge tray and the guide rail so as not to tilt the sheet discharge tray. Becomes large. Further, there is a problem that the incorporation is poor because the engagement amount of the stopper needs to be increased.

[0018]

In order to solve the above-mentioned problems, according to the first aspect of the present invention, a loading tray for loading a recording medium on which an image is recorded and discharged from the apparatus main body can be stored in the apparatus main body. In the recording apparatus having a, in the stacking tray, a guide member for guiding the recording medium discharged from the apparatus main body is attached so as to be set at a plurality of positions,

More specifically, a guide position (second set position) at which at least the lower surface of the recording medium discharged onto the stacking tray can be guided to the stacking tray, and a storage position where the stacking tray is housed. A guide member that can be set is attached to the (first setting position) and the guide member is set from the storage position to the guide position, so that the guide member and the stacking tray are lifted up with respect to the apparatus main body. ing.

With such a configuration, even if the guide member itself is small, the guide member can be moved substantially horizontally to the outside of the apparatus after image recording is completed. It can be set to a guideable height as it is. Therefore, it is possible to simultaneously reduce the cost and size of the recording apparatus and increase the resolution of the recorded image. Further, the present invention is also effective in a recording apparatus having a resolution comparable to that of the conventional art, because the size of the stacking tray can be reduced.

The guide member can be set at a plurality of guide positions, and the amount of lift-up is changed according to the guide position at which the guide member is set, so that an optimal discharge mode is selected according to the type of recording medium. You may make it take.

Further, driving means for setting and driving the guide member to each of the above positions by the driving force of the driving source may be provided.
Further, when the power of the apparatus is turned off, the guide member set at the guide position may be automatically driven to be set at the storage position.

According to a second aspect of the present invention, there is provided a recording apparatus having a loading tray on which a recording medium on which an image is recorded and which is discharged from the apparatus main body can be pulled out and stored in the apparatus main body. Are provided with a pair of stoppers which engage with each other when the stacking tray is pulled out, and the stopper pairs are provided at a plurality of positions in the pulling-out direction of the stacking tray.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment) FIGS. 1 to 8 show a recording apparatus according to a first embodiment of the present invention. A recording device 1 having an automatic paper feed mechanism includes a paper feed unit 2,
The printing apparatus includes a paper feeding unit 3, a paper discharging unit 4, a carriage unit 5, and a cleaning unit 6. Here, these will be sequentially described for each copy.

(A) Paper Feed Unit 2 The paper feed unit 2 is a pressure plate 21 on which a sheet material (recording medium) P is stacked.
And a paper feed roller 22 that feeds the sheet material P
0. The pressure plate 21 includes
The movable side guide 23 is provided so as to be movable, and regulates the loading position of the sheet material P. The pressure plate 21 is rotatable about a rotation shaft connected to the base 20, and is urged by a pressure plate spring 24 to the sheet feeding roller 22.

A separation pad 25 made of a material having a large coefficient of friction such as artificial skin is provided at a portion of the pressure plate 21 facing the paper feed roller 22 in order to prevent double feeding of the sheet material P.

Further, the base 20 covers a corner in one direction of the sheet material P, and a separation claw 26 for separating the sheet material P one by one, and a separation claw 26 which cannot be used such as a thick paper. A bank portion 27 integrally formed with the base 20 for separating objects and a release cam 29 for releasing the contact between the pressure plate 21 and the feeding roller 22 are provided.

In the above configuration, in the standby state, the release cam 29 pushes the pressure plate 21 down to a predetermined position. Thereby, the contact between the pressure plate 21 and the feeding roller 22 is released. Then, in this state, when the driving force of the transport roller 36 is transmitted to the feed roller 22 and the release cam 29 by a gear or the like, the release cam 29
The pressure plate 21 rises because it is separated from the sheet material P, and the feeding roller 22 and the sheet material P contact each other.

Then, as the feeding roller 22 rotates,
The sheet material P is picked up, separated one by one by a separation claw 26, and sent to the sheet feeding unit 3. At this time, the separation claw 26 is kept fixed to perform separation on paper without strain, such as plain paper. Separation claw 26 is separated from paper having a stiffness such as thick paper while being moved by the paper.

The feed roller 22 and the release cam 29 rotate until the sheet material P is fed into the paper feed unit 3, and are again in a standby state in which the contact between the sheet material P and the feed roller 22 is released. Thereafter, the driving force from the transport roller 36 is cut off.

(B) Paper Feeding Unit The paper feeding unit 3 is attached to a chassis 8 made of a bent sheet metal. The paper feeding section 3 has a transport roller 36 for transporting the sheet material P and a PE sensor 32.
The transport roller 36 has a configuration in which an elastic body such as rubber is wound around the surface of a metal shaft, and the metal portions of both shafts are received by conductive bearings 38 and 39 and attached to the chassis 8. A transfer roller tension spring 381 is provided between the bearing 38 and the transfer roller 36 to apply a rotational load to the transfer roller 36 and perform stable transfer, thereby urging the transfer roller 36. Is given a predetermined load.

A plurality of driven pinch rollers 37 are provided in contact with the transport roller 36. The pinch roller 37 is held by the pinch roller guide 30 and is urged by the pinch roller spring 31 so that the pinch roller 3
7 comes into pressure contact with the conveying roller 36 to generate a conveying force of the sheet material P.

The pinch roller 37 does not cover the entire area of the sheet material P, but is divided so as to cover only a predetermined area. Therefore, the portion without the pinch roller 37 is provided with the guide 301 from the pinch roller guide 30 to prevent the sheet material P from floating. At this time, the rotation shaft of the pinch roller guide 30 is attached to the bearing of the upper guide 33, and rotates around the bearing.

Further, an upper guide 33 for guiding the sheet material P is provided at an entrance of the sheet feeding section 3 to which the sheet material P is conveyed.
And a platen 34. In addition, upper guide 3
3 includes a PE sensor 32 for detecting the leading and trailing edges of the sheet P.
A PE sensor lever 35 is provided. The platen 34 fits with the transport roller 36 attached to the chassis 8, and is positioned by a sliding bearing 342 and an attachment shaft 343 directly attached to the chassis 8.

On the sheet reference side of the platen 34, a sheet retainer 344 that covers an end of the sheet material P is provided. As a result, even when recording is performed on the sheet material P whose end is deformed or curled as a whole, the sheet end is lifted and does not interfere with the carriage 50 or the recording head 7.

Further, a recording head 7 for forming an image based on image information is provided downstream of the conveying roller 36 in the sheet conveying direction.

In the above configuration, the sheet material P sent to the paper feeding section 3 is guided by the platen 34, the pinch roller guide 30 and the upper guide 33, and is placed between the pair of rollers including the transport roller 36 and the pinch roller 37. Sent.
At this time, the PE sensor lever 35 detects the leading end of the conveyed sheet material P, and thereby obtains the printing position of the sheet material P. Further, the sheet material P is LF (not shown).
The pair of rollers 36 and 37 are rotated by the motor and conveyed on the platen 34.

As the recording head 7, an easily replaceable inkjet recording head integrally formed with the ink tank is used. The recording head 7 can apply heat to the ink by a heater or the like. The ink causes film boiling due to the heat, and the ink is ejected from the nozzle 70 of the recording head 7 by a pressure change caused by the growth or shrinkage of bubbles due to the film boiling, and the sheet material P
An image is formed thereon.

(C) Carriage section The carriage section 5 has a carriage 50 for mounting and holding the recording head 7. The carriage 50 has a guide shaft 81 for reciprocating scanning in a direction perpendicular to the conveying direction of the sheet material P, and a guide rail 82 for holding a rear end of the carriage 50 and maintaining a gap between the recording head 7 and the sheet material P. Supported by These guide shafts 81 are attached to the chassis 8. The guide rail 82 is formed integrally with the chassis 8.

As described above, by forming the guide rail 82 integrally with the chassis 8, the number of parts and the number of mounting steps can be reduced, and the cost can be reduced. In addition, since the rigidity of the chassis 8 is increased by bending the guide rail 82, the reliability in terms of strength is improved.
Further, when the conventional strength is sufficient, the thickness of the sheet metal forming the chassis 8 can be reduced, so that the cost can be further reduced.

The carriage 50 is driven via a timing belt 83 by a carriage motor 80 attached to the chassis 8. The timing belt 83 is stretched and supported by an idle pulley 84. Further, the carriage 50 includes a flexible board 56 for transmitting a head signal from the electric board 9 to the recording head 7.

In the above configuration, when an image is formed on the sheet material P, the roller pair 36, 37 conveys the sheet material P to the line position (position in the conveying direction of the sheet material P) where the image is formed, and the carriage motor 80 Carriage 5
0 is moved to the row position where the image is formed (the position perpendicular to the conveying direction of the sheet material P), and the recording head 7 is opposed to the image forming position. Thereafter, the recording head 7 ejects ink toward the sheet material P in response to a signal from the electric substrate 9 to form an image.

(D) Paper Discharge Unit The paper discharge unit 4 includes a transmission roller 4
0, and a paper discharge roller 41 abutting on the transmission roller 40
It is composed of Therefore, the transport rollers 36
Drive force is transmitted via the transfer roller 40 to the discharge roller 41
Is transmitted to Further, a spur 42 is in contact with the paper discharge roller 41 so as to be rotatable following the paper discharge roller 41. The spur 42 is attached to an integral spur stay 341 provided on the platen 34.

As described above, by providing the spur stay 341 integrally with the platen 34, the dimensions of the spur 42 and the paper discharge roller 41 can be controlled in the same part, so that the dimensional relationship can be maintained stably. Can be.

The spur stay 341 has a cutout 342 so that the carriage 50 moves to this position when the head 7 is replaced, and the hook lever 53 for attaching and detaching the head 7 can be operated. Space is secured.

With the above configuration, the sheet material P on which an image has been formed by the carriage unit 5 is discharged by the discharge roller 41 and the spur 4
2 and is conveyed and discharged to a paper discharge tray (loading tray in claims) 10.

(E) Cleaning Unit The cleaning unit 6 includes a pump 60 for cleaning the recording head 7, a cap 61 for suppressing the drying of the recording head 7, and a driving force from the transport roller 36 for the paper feeding unit 2.
And a drive switching arm 62 for switching to the pump 60. When the drive switching arm 62 is not feeding or cleaning, a planetary gear (not shown) that rotates around the axis of the transport roller 36 is fixed at a predetermined position. No power is transmitted. When the drive switching arm (not shown) is switched by the movement of the carriage 50, the planetary gears become free, so that the planetary gears move in accordance with the forward and reverse rotations of the transport roller 36. Thus, when the transport roller 36 rotates forward, the driving force is transmitted to the paper feeding unit 2, and when the transport roller 36 rotates reversely, the driving force is transmitted to the pump 60.

(F) Exterior The exterior is composed of a base 11 and an upper cover 12 as shown in FIG.
And a front cover 13. A discharge tray 10 is slidably attached to a lower portion of the base 11 so that the tray can be pulled out from the base 11 and stored in the base 11.

Next, the configuration of the paper discharge tray 10 will be described in detail with reference to FIGS. The paper discharge tray 10 includes a main paper discharge tray 44, a sub paper discharge tray 45, and first and second paper discharge guides (guide members) 46, 47 provided on the left and right sides of the main paper discharge tray 44. It is configured.

As shown in FIGS. 3 and 4, the sub-discharge tray 45 is mounted substantially at the center of the main discharge tray 44 so as to be capable of being pulled out and stored. When stacking the sheet material P on the sheet discharge tray 10, the sub-sheet discharge tray 45 is pulled out to have a length necessary for stacking the sheet P. In this way, by making the discharge tray 10 divided into two, the size of the discharge tray 10 can be reduced.

The first and second discharge guides 46 and 47
The main discharge tray 44 is disposed on the left and right sides of the main discharge tray 44 at substantially the same interval as the width of the sub discharge tray 45. The first and second paper ejection guides 46 and 47 fall into the main paper ejection tray 44 in a storage position (first set position) in which they are stored in a substantially parallel manner, and a guide position (a second set position) which stands substantially vertically. (Set position) so as to be rotatable.

Concave portions 444 and 445 are formed in the main discharge tray 44 at the storage portions of the respective discharge guides 46 and 47. For this reason, each of the paper discharge guides 46 and 47 can be accommodated within a substantial thickness of the main paper discharge tray 44.
Then, the respective discharge guides 46 and 47 are connected to the main discharge tray 4.
4 and the output tray 10 is
1 can be accommodated in the base 11 by being slid toward the apparatus main body along the guide rail 111 provided at the lower portion of the base 1.

When the discharge tray 10 is used, as shown in FIG. 3, the sub discharge tray 45 is pulled out substantially horizontally while holding the operation section 451 of the sub discharge tray 45. When a predetermined amount is withdrawn, FIG.
As shown in (b), the stoppers 442 provided on the main paper output tray 44 and the stoppers 112 provided on the base 11 (a pair of stoppers referred to in the claims) are engaged, and the guide rail of the paper output tray 10 is engaged. Exit from 111 is regulated.

Further, in consideration of the case where the main paper discharge tray 44 is inclined, the position of the main paper discharge tray 44 and the base 11 which is located on the back side of the stoppers 442 and 112 is shown in FIG. Stoppers 442, 11 as shown
The sub-stopper 44 is located at a position on the outer side in the width direction than that of
3, 113 (stopper pairs referred to in the claims) are provided. Thus, even if the main discharge tray 44 in FIG. 8 is tilted and the stoppers 442 and 112 come off, the sub-stoppers 443 and 113 are engaged, so that the discharge tray 10 is prevented from coming off the guide rail 111.

Therefore, the fitting length between the main discharge tray 44 and the guide rail 111 is shortened to reduce the main discharge tray 44
Even if it is inclined, it does not come off, so that even if the size of the main discharge tray 44 is reduced, it is possible to secure a sufficient amount of drawing out of the main discharge tray 44. Also,
Since the heights of the stoppers 442 and 112 can be made lower than before, the incorporation at the time of assembly is also improved.

Next, the first and second discharge guides 46, 4
7 will be described in detail. As shown in FIG. 6, the first and second paper ejection guides 46 and 47 are composed of sheet receiving portions (body portions) 464 and 474 and rotation shafts 462 and 4 that are rotatably attached to the main paper ejection tray 44.
63, 472, 473 and cam portions 461, 471 provided on opposite sides of the sheet receiving portions 464, 474 with the rotating shafts 461, 472 interposed therebetween, and are integrally formed.

As shown in FIG. 4, the paper ejection guides 46 and 47 have the rotating shafts 462 and 472 on the side where the cam portions 461 and 471 are formed, facing the main body of the main paper ejection tray 44. It is attached to the main paper output tray 44.

When the user manually raises the paper ejection guides 46 and 47 in the state where the paper ejection tray 10 is pulled out from the apparatus main body and sets the paper ejection guides at the guide positions as shown in FIG. 4, the sheet receiving portions 464 and 474 are moved. The cam portions 461 and 471 stand on the front surface side of the main discharge tray 44 and protrude on the rear surface side of the main discharge tray 44.

For this reason, as shown in FIG. 5, if there is a floor surface (device installation surface) below the main discharge tray 44 that is pulled out substantially horizontally from the main body of the device, the cam portions 461 and 471 will be placed on the floor surface. , The entire sheet discharge tray 10 is lifted up so that the sheet receiving portions 464 and 474 of the sheet discharge guides 46 and 47 are raised. As shown in the figure, the lift-up amount of the paper discharge tray 10 is determined by the positions of the contact portions between the cam portions 461 and 471 and the floor surface, and the working portions of the main paper discharge tray 44 and the stoppers 112 and 442 of the base 11. (fulcrum)
Is determined by the position.

Here, since the sheet receiving portions 464 and 474 of the paper ejection guides 46 and 47 and the cam portions 461 and 471 are located at positions directly opposite to the rotating shafts 462 and 472 of the paper ejection guides 46 and 47, the main body is provided. The discharge tray 44 can be lifted up with a simple configuration.

As shown in FIG. 7, when the sheet material P is discharged in a substantially horizontal direction by the discharge roller 41, the sheet receiving portions 464 of the discharge guides 46 and 47 lifted up.
474 keeps the sheet material P substantially horizontal.

With the above configuration, the paper ejection guides 46 and 47
Even if the size of the sheet discharge tray 10 is not increased, the behavior of the sheet material P can be reliably suppressed, and high-resolution image recording can be performed while avoiding an increase in cost and size.

In a recording apparatus having the same resolution as that of a conventional recording apparatus, the size of the discharge tray 10 can be reduced by adopting the same configuration, which is effective for cost reduction and size reduction.

(Second Embodiment) In the first embodiment,
Although the case where the user manually sets the position of the paper ejection guides 46 and 47 has been described, as shown in FIG. 9, a stepping motor 48, a motor gear 481 attached to an output shaft of the motor 48, and Motor gear 4
A gear train (48) for transmitting the rotational force of 81 to input gears 465 and 475 attached to the rotation shafts of the paper discharge guides 46 and 47.
1, 493, 492, etc.). The other configurations in the present embodiment are the same as those in the first embodiment.

When the motor 48 is rotated in one direction, the first discharge guide 46 and the second discharge guide 47 rotate in directions opposite to each other, so that the motor gear 481 and the output gear 4 are rotated.
An idler gear 493 is inserted between the rotation direction 92 and the rotation direction 92.

This drive mechanism operates the input gear 465 and the input gear 465 only when the main discharge tray 44 is pulled out from the apparatus main body.
475 and the output gears 491 and 492 of the gear train are meshed with each other so that the driving force can be transmitted.

A control circuit (not shown) for controlling the stepping motor 48 controls the motor by a predetermined number of pulses when it is determined that the discharge guides 46 and 47 need to be raised to the guide position in accordance with print information from the host. By rotating 48, the discharge guides 46 and 47 are set at the guide position.

In the first embodiment, the case where the set positions of the paper discharge guides 46 and 47 are the guide position and the storage position which are substantially perpendicular to the main paper discharge tray 44 has been described. The guide positions of the discharge guides 46 and 47 may be plural. In this case, for example, if the driving mechanism shown in FIG. 9 is used, by changing the number of pulses applied to the motor 48 depending on the difference in the sheet material P, it is possible to set an optimal discharge mode according to the type of the sheet material P. It becomes possible.

Further, the rotation angles of the paper ejection guides 46 and 47 can be changed even during recording on the same sheet material P, and an optimal ejection form can be set according to the situation.

When the user turns off the power of the recording apparatus 1, the drive mechanism is operated so that the paper discharge guides 46 and 47 set at the guide position are always returned to the storage position. Accordingly, it is possible to completely automate the operation of raising and storing the paper discharge guides 46 and 47 which may be troublesome for the user.

(Third Embodiment) In the first and second embodiments, the recording device 1 is slid by sliding the discharge tray 10.
As described in FIG. 10, the paper discharge tray 210 is attached to the apparatus main body so as to be rotatable in the vertical direction, and is housed so as to cover the front surface of the apparatus main body as shown in FIG. Good. Note that the basic configuration of the present embodiment is the same as the first and second embodiments, and thus common components are denoted by the same reference numerals as in the first and second embodiments.

More specifically, a boss 114 serving as a rotation shaft is provided on the base 11, and a receiving portion 246 of the main paper discharge tray 244 is rotatably mounted on the boss 114. Paper ejection guides 46, 4
Reference numeral 7 denotes a discharge guide 4 which is rotatably mounted on the main discharge tray 244 as in the above-described embodiments.
6 and 47 are lifted to the guide position,
61 and 471 project below the main paper discharge tray 244 and come into contact with the floor surface. As a result, the entire discharge tray 210 is lifted from the floor. The lift-up amount is determined by the position of the rotation shaft 446 and the contact position between the cam portions 461 and 471 and the floor.

As in the present embodiment, the front surface of the apparatus is covered by the paper discharge tray 210 in the housed state, so that the paper discharge tray 10 is slid and stored in the lower part of the apparatus as in the above embodiments. The device size can be reduced.

In each of the above embodiments, the case where the discharge tray is lifted up by the contact of the cam portion of the discharge guide with the floor on which the recording apparatus is installed has been described, but the discharge tray is set at the guide position. A part of the paper ejection guide may be brought into contact with or engaged with the apparatus main body to lift up.

[0076]

As described above, according to the first aspect of the present invention, by changing the set position of the guide member, the position of the entire stacking tray to which the guide member is attached is changed (lifted up). Therefore, even if the guide member itself is small, it is necessary to set the guide member at a position where the portion of the recording medium, which is substantially horizontally discharged to the outside of the apparatus after the image recording is completed, can be guided while remaining substantially horizontal. Can be. Therefore, it is possible to simultaneously reduce the cost and size of the recording apparatus and increase the resolution of the recorded image. Further, the present invention is also effective in a recording apparatus having a resolution comparable to that of the conventional art, because the size of the stacking tray can be reduced.

If the guide member can be set at a plurality of guide positions and the amount of lift-up is made different according to the guide position at which the guide member is set, the optimum value can be set according to the type of recording medium. The discharge form can be taken.

The guide member is automatically set to the guide position by a signal from an external device or the like, or the guide member is automatically set to the storage position when the power supply of the device is turned off. Then, it is possible to prevent the user from feeling bothered about using the guide member and from causing an operation error.

Further, according to the second aspect of the present invention, even when the loading tray is inclined due to a short slide fitting length between the loading tray and the apparatus main body, any one of the pair of stoppers is engaged. The tray can be reliably prevented from coming off from the apparatus main body. In addition, it is not necessary to increase the size of the pair of stoppers that are normally engaged, so that deterioration in assemblability can be prevented.
