Description

  The present invention relates to a recording apparatus that records an image on a recording medium using a recording head based on image information, and more particularly to a recording apparatus having a novel ejection mechanism for ejecting the recording medium.

  The recording apparatus is widely used as an image data output apparatus in an image forming apparatus having functions such as a printer, a copier, and a facsimile, or a composite electronic apparatus including a computer and a word processor, a workstation, and the like. These recording apparatuses are configured to form images (including characters and symbols) on recording media such as paper, cloth, plastic sheets, and OHP sheets based on image information. There are two types of recording systems in this recording apparatus: a serial type and a line type. The serial type is a system in which an image is recorded while alternately repeating main scanning for moving the recording head along the recording sheet and sub-scanning for feeding the recording sheet at a predetermined pitch.

On the other hand, in the line type, by using a long recording head extending in the width direction of the recording sheet, an image is recorded only by paper feeding (sub scanning) of the recording sheet while recording one line at a time. It is a method. The recording apparatus can be classified into an inkjet recording apparatus, a thermal transfer recording apparatus, a laser recording apparatus, a thermal recording apparatus, a wire dot recording apparatus, and the like according to a recording method. When an image is recorded on a large-size recording medium with a large format printer or the like, roll paper wound in a roll shape is unwound and conveyed to an image forming unit to form an image. A recording medium on which an image is formed is cut into an appropriate length, and a plurality of cut recording media are stacked and stored on a paper receiving tray.

  However, in the above-described recording apparatus, particularly when an image is recorded on a large-size recording medium with a large-format printer or the like, the following problems occur when the recording medium discharged after image recording is accommodated in an accommodating means such as a tray. was there. First, for example, roll paper wound in a roll shape may be used as a recording medium, and recording may be performed on roll paper that is sequentially unwound. In particular, in this case, the roll paper itself has a curl-like tendency, so the tendency is not eliminated even after recording, and the roll paper is discharged in a curled state (curled state) with the recording surface facing outward. There is. When a plurality of recording media are ejected in this state, the recording medium that has already been ejected in a state of being curled outwardly and the newly ejected recording medium rub against each other, and the recording surface of the recording medium is scratched. There is inconvenience that it is easy to stick. A similar problem occurs when recording on a cut sheet.

  Secondly, when a plurality of recording media to be recorded and discharged are stored in a basket or a discharge tray, between the recording medium that has already been stored after image recording and the newly discharged recording medium. The slipperiness becomes worse. For this reason, there is a tendency that a newly ejected recording medium is caught by a recording medium already accommodated. For this reason, the rear end portion of the recording medium is not sufficiently discharged from the discharge port, which may cause a discharge failure or the recording medium discharged later may not be accommodated in the basket. As a result, there has been a problem that the recorded recording medium comes into contact with the floor or the like.

  Third, in the case of a recording medium such as plain paper that is weak, the paper size is large, so it bends due to the weight of the recording medium itself and is loaded in a folded state when stored in a basket or the like. There was also an inconvenience. There are proposals for a take-up device or the like for solving this problem, but there are problems such as an increase in size of the device and poor handling of the recording medium after paper discharge.

  The present invention has been made in view of such technical problems. It is an object of the present invention to stably store discharged recording media, and even when a plurality of discharged recording media are stacked and stored, the recording surface of each recording medium is not degraded. It is to provide a recording apparatus provided with a discharge mechanism that can be accommodated in a state.

  The present invention relates to a recording apparatus that records an image on a recording medium by a recording head based on image information and discharges the recorded recording medium. The recording apparatus according to the present invention includes grip means capable of gripping a leading end portion of a discharged recording medium, and storage means for storing the discharged recording medium. Therefore, the recording medium discharged along with the recording is introduced into the storage means by gripping the leading end portion of the discharged recording medium with the grip means.

  Another embodiment of the present invention also relates to a recording apparatus that records an image on a recording medium by a recording head based on the image information, and discharges the recorded recording medium. This recording apparatus accommodates the ejected recording medium, grip means capable of gripping the leading end of the discharged recording medium, a guide member for introducing the leading end of the ejected recording medium into the gripping means. For this purpose, a receiving means is provided below the guide member. Therefore, after gripping the leading end portion of the recording medium to be ejected by the grip means, the guide member is retracted from the leading end introduction position, and is ejected along with recording and is loosened between the recording apparatus and the grip means. The recording medium hanging down is introduced into the storage means.

  According to the present invention, the discharged recording medium can be stably stored, and even when a plurality of discharged recording media are stacked and stored, the recording surface of each recording medium is stable without deterioration. Provided is a recording apparatus including a discharge mechanism that can be accommodated in a state.

  Embodiments of the present invention will be specifically described below with reference to the drawings. Note that the same reference numerals denote the same or corresponding parts throughout the drawings. FIG. 1 is a perspective view showing a schematic configuration of a recording apparatus according to an embodiment of the present invention. FIG. 2 is a longitudinal sectional view of the recording apparatus of FIG. 1 and 2, the recording apparatus 1 includes a roll holder unit 10, an image forming unit 20, and a paper discharge unit 30. The roll holder unit 10 is a mechanism unit for winding and holding a roll-shaped sheet (also referred to as roll paper) Pr as a recording medium in a rotatable manner. The image forming unit 20 is a mechanism unit that records an image on the roll paper Pr fed and conveyed from the roll holder unit. The paper discharge unit 30 is a mechanism unit for discharging the image-formed sheet to the outside of the apparatus main body.

  The roll holder unit 10 is provided with a rotatable spool 11. Flange 12L, 12R is provided on both sides of the spool. Roll paper Pr is wound on the spool 11 in a state where the position in the width direction is regulated by the flanges 12L and 12R. Both ends of the spool are pivotally supported with respect to the apparatus frame via bearings 13L and 13R. In order to facilitate replacement of the roll paper, sliding slopes 13'L and 13'R are arranged in front of the bearings 13L and 13R. The user attaches / detaches (exchanges) the roll paper Pr along the slope.

  The left end portion of the spool 11 is provided with a rotation load means (torque limiter) 11L configured not to transmit drive torque to the spool until the rotation load of the spool reaches a certain value. After the spool 11 on which the roll paper Pr is set is mounted on the roll holder unit 10, the drive of a conveyance motor (LF motor) (not shown) is transmitted to the rotational load means via the gear train 14, thereby Unwinding (feeding) is performed. The image forming unit 20 is provided with a transport roll 21 for feeding a recording medium for image formation. The transport motor is essentially for driving the transport roller 21. In the present embodiment, the roll paper Pr can be conveyed in the forward direction and the reverse direction by rotating the transport roller 21 forward and backward by forward and reverse rotation of the feed motor. A lower guide 15 serving as a guide (or support) when the user feeds the leading end of the roll paper Pr to the image forming unit 20 is disposed below the roll paper Pr to be sent out. An upper guide 16 is provided at a position facing the lower guide.

  1 and 2, the conveyance roller 21 constitutes a conveyance unit for intermittently feeding a roll paper Pr as a recording medium at a predetermined pitch when recording. The image forming unit 20 is provided with a plurality of pinch rollers 22 that are driven and rotated by contacting the conveying roller 21 with a predetermined pressing force, and a platen 23 for guiding and supporting the roll paper at a position facing the recording head 41. It has been. In the present embodiment, the suction platen 23 that guides and supports the recording medium in a flat shape while sucking the recording medium from the back surface with a negative pressure is used. In addition, the image forming unit is provided with a carriage 40 that is mounted with a recording head 41 and can reciprocate in a direction (X direction, main scanning direction) intersecting the transport direction (Y direction, sub-scanning direction). Note that the material of the recording medium Pr is not limited to paper or a plastic sheet, and various materials can be used as long as the image can be recorded.

  Here, the carriage 40 on which the recording head 41 is mounted will be described. In the present embodiment, an ink jet recording head that records an image by ejecting ink onto the recording medium Pr based on image information is used as the recording head 41. Therefore, the recording apparatus shown in this embodiment is an ink jet recording apparatus. An ejection port array including a plurality of ejection ports is formed on the ejection surface of the recording head facing the recording surface of the recording medium. In synchronization with the main scanning movement of the carriage 40, the recording head 41 is driven based on the image data, thereby forming an image by ejecting ink from the plurality of ejection ports toward the recording paper Pr. In the present embodiment, the case where the recording apparatus 1 is an ink jet recording apparatus is illustrated, but the present invention is a recording apparatus that uses other recording methods such as a laser beam type, a thermal transfer type, a thermal type, and a wire dot type. However, the same applies.

  The apparatus main body is provided with a main stay 50 arranged in the main scanning direction. A main rail 51 and a sub rail 52 extending in the width direction of the recording medium are fixed to the main stay in parallel to each other. The carriage 40 is supported by the bearings 42 and 43 so as to be reciprocally movable along the rails 51 and 52. The bearings 42 and 43 are provided at predetermined intervals in the front and rear direction of the carriage 40, and one (rear) bearing 43 is attached to the carriage 40 so as to be slidable in the front and rear direction. A spring 43a is mounted between the carriage 40 and the bearing 43, and the bearing 43 is pressed against the sub rail 52 by the biasing force of the spring. With such a configuration, the carriage 40 is always urged toward the main rail 51, and the vibration of the carriage 40 during the recording operation, the shake of the recording head 41 due to the bearing looseness, and the like are prevented. This enables high-quality image formation.

  A linear sensor 44 is mounted above the bearing 43 of the carriage 40. This linear sensor reads an optical linear scale 53 attached to the main stay 50 so as to extend in the main scanning direction. By this reading signal, drive control of the carriage 40 and image formation control of the recording head 41 are performed. The carriage 40 is moved by transmitting a drive of a carriage motor (not shown) provided near one end of the main stay 50 via the carriage belt 54. In synchronization with the movement of the carriage 40, the recording head 41 is driven based on the image data (image information), thereby forming an image on the roll paper Pr. The recording medium on which an image is formed while being conveyed by the conveying roller 21 along the platen 23 is discharged from the paper discharge unit 30 to the outside of the apparatus main body by the conveying roller.

  3 is a partial longitudinal sectional view showing a standby state of the paper discharge mechanism of the paper discharge unit 30 of the recording apparatus of FIG. In FIG. 3, a guide unit 31 for guiding the roll paper (recording medium) Pr discharged by the transport roller 21 is provided on the downstream side of the platen 23 in the transport direction. A guide member 101 that is rotatable about a shaft 102 provided in an apparatus frame (not shown) is disposed on the downstream side in the conveyance direction of the guide portion. The guide member is rotated by controlling a driving unit (not shown). In addition, a grip member 111 that can be rotated counterclockwise in the figure about a shaft 112 provided on the apparatus frame (frame) is located at a position (right position in the figure) that is separated from the apparatus main body from the guide member 101. A grip means 110 is provided. As shown in FIG. 3, the grip member 111 is disposed in the vicinity of the upper right end portion of the paper receiving tray 12 serving as a storage unit.

  An opening 111a is formed at the tip of the grip member 111, and a grip 115 (FIG. 9) for gripping the tip of the recording medium is formed inside (back) of the opening. Below the guide member 101, a paper receiving tray 121, which is a storage unit for storing the recording medium cut and discharged, is disposed. This paper receiving tray is for placing the discharged recording medium, and its vertical cross-sectional shape is substantially U-shaped with the upper part opened. Therefore, the grip member 111 is regulated to a substantially horizontal position shown in FIG. 3 in the standby state. Further, when the leading end portion of the recording medium is introduced and gripped by the gripping portion 115 described later, the grip member is released from the position restriction in the rotational direction and rotated about the shaft 112 in the counterclockwise direction in the figure. The That is, when the recording medium that has been recorded and cut is placed on the paper receiving tray 121, the recording medium is controlled to return to the substantially horizontal initial position.

  FIG. 4 is a partial longitudinal sectional view showing a state at the start of recording of the paper discharge mechanism of FIG. FIG. 5 is a partial vertical cross-sectional view showing a state when the paper discharge proceeds from the state of FIG. 4 and the leading end of the recording medium reaches the grip means. FIG. 6 is a partial vertical cross-sectional view showing a state in which the paper discharge is further advanced from the state of FIG. FIG. 7 is a partial longitudinal sectional view showing a state where the recording medium is cut at the rear end when image recording is completed in the paper discharge mechanism of FIG. FIG. 8 is a partial longitudinal sectional view showing a state in which the recording medium cut in FIG. 7 is accommodated in the accommodating means. Next, with reference to FIGS. 4 to 8, the recording medium discharge operation by the paper discharge mechanism according to the present embodiment will be described.

  When the recording operation in the image forming unit is started, the guide member 101 is centered on the shaft 102 in the direction of arrow a (counterclockwise in the figure) before the leading end of the recording medium Pr is slightly discharged as shown in FIG. Is rotated. That is, the guide member 101 is rotated from the retracted position to the guide position. As a result, the position where the tip 101a of the guide member 101 approaches the opening 111a of the grip member 111, that is, the guide member 101 can introduce the tip of the recording medium into the grip 115 (FIG. 9) in the opening 111a. Set (stop) to position. When the paper discharge progresses from the state of FIG. 4 and the recording medium Pr reaches the grip means 110, as shown in FIG. 5, the leading end of the recording medium is introduced into the grip portion 115 in the opening 111a as shown in FIG. Is done. Then, the guide member 101 is rotated in the direction of arrow b, returned to the initial position, and stopped. In this way, the guide member 101 is retracted, and at the same time, the position restriction in the rotational direction of the grip member 111 is released, and the grip member can be rotated about the shaft 112 in the counterclockwise direction shown in the drawing.

  When the paper discharge further proceeds from the state of FIG. 5, the grip member 111 is rotated counterclockwise as shown by an arrow c as shown in FIG. 6, and the opening 111 a faces downward toward the paper receiving tray 121. It is turned to the position. As a result, the vicinity of the leading end of the recording medium Pr is bent in a downward U-shape, and is directed in the direction of feeding into the paper receiving tray 121 serving as a storage unit. As the discharge progresses, the recording medium (roll paper) Pr bends in the vicinity of the leading end, and hangs down in the direction of arrow d toward the storage means 121 while slacking in a U shape as shown in FIG.

  Next, when the image formation is completed up to the rear end of the recording medium, as shown in FIG. 7, the cutting means (cutter) 45 attached to the carriage 40 moves in the direction of arrow e, and the carriage 40 operates in the scanning direction. Accordingly, the recording medium is cut in the width direction at the rear end. The cut recording medium falls toward the inside of the accommodating means 121 (in the direction of arrow f) by its own weight. As shown in FIG. 8, the recording medium that is cut and dropped is introduced into the storage means 121 and stored in a loaded state. When a plurality of recording media are sequentially ejected, the next recording medium introduced onto the already accommodated recording medium is also stacked (placed) in the same posture. The shape structure of the paper receiving tray 121 serving as a storage means is such that the recording medium Pr is lower in the rear end portion on the open side where the recording medium Pr has dropped than the front end portion on the side gripped by the grip member 111. It is configured to be accommodated.

  Therefore, when the recording medium Pr drops into the paper receiving tray 121, the recording medium Pr is not affected by the curl wrinkles of the recording medium itself, and does not curl or bend on the mounting surface of the paper receiving tray 121. It can be copied and stored, and can be further stacked. When the recording medium is placed (accommodated), as shown in FIG. 8, the cutter (cutting means) 45 is moved in the upward direction indicated by the arrow g. Thus, when the rear end portion of the recording medium that has finished recording is cut, the grip member 111 is rotated in the clockwise direction indicated by the arrow h, and the front end portion of the recording medium is released from the grip portion 115 as will be described later. The grip member 111 is detached. Then, the grip member is rotated to the substantially horizontal initial position and is held in this position in a position-restricted state. According to the paper discharge mechanism described above, even when a plurality of recording media are sequentially accommodated in the paper receiving tray 121, a number of sheets are stored in the paper receiving tray 121 by repeating the series of operations shown in FIGS. Recording media Pr can be stacked in the same posture in an orderly manner.

  FIG. 9 is a side view showing the internal structure of the grip means 110 of the paper discharge mechanism of FIG. FIG. 10 is a side view showing a state when the leading end of the recording medium is inserted into the grip 115 from the opening 111a of the grip means of FIG. FIG. 11 is a side view showing a state where the leading end portion of the recording medium is detached from the grip portion 115 of the grip means of FIG. Next, the configuration and operation of the grip means 110 will be described with reference to FIGS. 9 to 11, a grip portion 115 is configured at the back of the opening 111 a of the grip member 111. This gripping portion is configured by arranging a roller 113 and a spring 114 in a space formed between upper and lower wedge-shaped inclined surfaces 111b and 111c. The upper and lower slopes 111b and 111c are formed so that the distance between them is narrowed to the left in the figure. Further, a stopper surface 111d is formed at the entrance (the left end portion in the drawing) of the lower slope 113. The roller 113 is urged by a spring 114 with a weak pressing force toward the left in the figure, and is in contact with the upper and lower wedge-shaped inclined surfaces 111b and 111c.

  When the leading end of the recording medium Pr is introduced into the inside from the opening 111a of the grip member 111, the leading end is sandwiched between the roller 113 and the upper slope 111b, as shown in FIG. This state corresponds to the state when the leading end of the recording medium in FIG. 5 reaches the grip means, and then the grip member 111 is rotated to a downward position as shown in FIG. Then, as the paper discharge conveyance proceeds, the recording medium Pr is introduced into the paper receiving tray 121 while its front end is bent in a U-shape. At this time, the grip member 111 is biased about the shaft 112 in the illustrated counterclockwise direction (FIG. 10) indicated by an arrow k. For this reason, even when an external force is applied to the recording medium Pr in a direction away from the grip member 111, the leading end of the recording medium is maintained between the roller 113 and the inclined surface 111b. Therefore, the recording medium is held in a state of being gripped (gripped) by the gripping portion 115 even when it is fed into the accommodating means 121 as shown in FIGS.

  As shown in FIG. 8, when the recording medium that has finished recording is cut, the grip member 111 is controlled to rotate in a direction (arrow h direction) to return to the initial position. At this time, since the grip member 111 rotates in the direction indicated by the arrow i in FIG. 11, the roller 113 receives a downward force from the recording medium Pr. As a result, the roller 113 moves in the direction of arrow j in FIG. 11 along the lower slope 111c. As a result, a slight gap is generated between the roller 113 and the upper slope 111b, and the gripping force of the gripper 115 on the recording medium is released. As a result, the recording medium Pr is detached from the grip means 110 (grip member 111).

  The recording apparatus according to the embodiment described above includes a paper discharge mechanism that records an image on a recording medium by a recording head based on image information and discharges the recorded recording medium. This recording apparatus includes grip means 110 capable of gripping the front end portion of the discharged recording medium Pr, and a guide member 101 for introducing the front end portion of the discharged recording medium into the grip means. In addition, the recording apparatus includes storage means 121 disposed below the guide member in order to store the discharged recording medium. Therefore, after gripping the leading end of the recording medium to be ejected by the grip means, the guide member is retracted from the leading end introduction position, and the recording medium ejected along with recording is introduced to the accommodating means by the grip means. Configured to go. According to such a configuration, the discharged recording medium can be stably stored, and even when a plurality of discharged recording media are stacked and stored, the recording surface of each recording medium is stable without deterioration. Provided is a recording apparatus including a discharge mechanism that can be accommodated in a state.

  FIG. 12 is a partial vertical cross-sectional view illustrating the configuration (standby state) of the paper discharge mechanism of the recording apparatus according to the second embodiment. FIG. 13 is a partial vertical cross-sectional view showing a state when recording by the paper discharge mechanism of FIG. 12 is started and the leading end of the recording medium is gripped by the grip means. FIG. 14 is a partial longitudinal sectional view showing a state in which the grip means holding the leading end of the recording medium has moved to a position away from the image forming unit as the paper discharge proceeds from the state of FIG. FIG. 15 is a partial vertical cross-sectional view showing a state in which the paper discharge is further advanced from the state of FIG. 14 and the recording medium is fed into the accommodating means while being bent in a U shape near the front end.

  In FIG. 12, a guide unit 31 for guiding the roll paper (recording medium) Pr discharged by the transport roller 21 is provided on the downstream side of the platen 23 in the transport direction. On the extension line of the guide part, the grip means 110 is arranged so as to be movable in a direction approaching and separating from the discharge part (or the image forming part 20 and the platen 23). The grip means 110 has the same configuration as that of the first embodiment described with reference to FIGS. Below the grip means 110, a paper receiving tray 121, which is a storage means similar to that of the first embodiment, is disposed. As the moving means of the grip means 110, for example, the grip means is supported so as to be able to reciprocate along a guide path provided on the frame of the apparatus main body, and the movement control is performed using the drive means and the drive transmission mechanism. Is used.

  In the standby state, the grip unit 110 is held at a position on the side away from the discharge unit (or the image forming unit 20) as shown in FIG. After image recording is started, the grip means is moved to a position closer to the discharge section. Therefore, after gripping the leading end of the recording medium Pr to be ejected by the grip means 110, the grip means is moved in a direction away from the ejecting section (a rightward direction in the drawing) at a speed corresponding to the feeding of the recording medium. In the present embodiment, the guide member 101 in the first embodiment is not provided. The paper discharge mechanism of this embodiment is different from the first embodiment in the above points, but has substantially the same configuration in other points. Accordingly, corresponding portions are denoted by the same reference numerals, and detailed description thereof is omitted.

  Next, a recording medium ejection operation according to the second embodiment will be described with reference to FIGS. When the recording operation is started from the standby state shown in FIG. 12, as shown in FIG. 13, the grip unit 110 is moved in the left direction by a driving unit (not shown) and is near the discharge port, that is, the image forming unit 20. Stop at a position close to (or the platen 23). Then, the leading end portion of the discharged recording medium is gripped by the grip portion 115 inside the grip member 111 as shown in FIG. Next, as shown in FIG. 14, as the discharge of the recording medium proceeds, the grip member 111 that holds the tip of the recording medium moves in the separation direction indicated by the arrow A at a speed corresponding to the discharge speed. By the separation movement of the grip member, as shown in FIG. 14, a space for dropping the discharged recording medium onto the paper receiving tray 121 is formed.

  When the grip member 111 reaches the separation position set in the vicinity of the right upper end 121a of the storage means 121, the grip member 111 is stopped at this position. Therefore, as in the first embodiment, the restriction on the rotational direction of the grip member 111 is released, and the grip member 111 is rotated about the shaft 112 in the counterclockwise direction shown by the arrow c as shown in FIG. It is done. The grip member 111 has the same configuration as that of the first embodiment described above, and a similar gripping portion 115 is provided therein.

  When the discharge of the recording medium proceeds from the state of FIG. 14, as shown in FIG. 15, the vicinity of the leading end of the discharged recording medium Pr is directed downward by the grip member 111 that is rotated downward in the direction of the arrow c. It is bent into a U shape. At the same time, the recording medium to be fed is directed in the direction of arrow d toward the paper receiving tray 121. Then, the recording medium sequentially advances in the direction of the arrow d as the discharge operation proceeds, and is introduced (sent into) the paper receiving tray 121. Also in this embodiment, when the recording on the recording medium Pr is completed up to the rear end, the cutting means 45 attached to the carriage 40 moves in the direction of arrow e. Then, using the movement of the carriage 40 in the scanning direction, the recording medium is cut at the rear end.

  The cut recording medium falls due to its own weight and is placed on the paper receiving tray 121. Also in this embodiment, when the recording medium that has finished recording is cut, the grip member 111 is rotated counterclockwise in the figure about the shaft 112 and returned to the initial position as shown in FIG. At this time, the leading end portion of the recording medium is released from the grip member 111 and separated by the same operation as in the first embodiment. That is, the roller 113 receives a downward force from the recording medium Pr by the rotation of the grip member 111 in the direction of the arrow i in FIG. As a result, the roller 113 moves in the direction of arrow j in FIG. 11 along the lower slope 111c. As a result, a slight gap is generated between the roller 113 and the upper slope 111b, and the gripping force of the gripper 115 on the recording medium is released. As a result, the recording medium Pr is detached from the grip member 111, and the paper discharge mechanism is again returned to the initial state shown in FIG.

  The second embodiment described with reference to FIGS. 12 to 15 has the same configuration as that of the first embodiment described with reference to FIGS. 1 to 11 in other respects, and corresponding parts are denoted by the same reference numerals. Detailed description thereof will be omitted. The second embodiment includes grip means 110 that can grip the leading end of the ejected recording medium Pr, and accommodation means 121 that accommodates the ejected recording medium. In addition, the accommodating means is arranged below the grip means, and the grip means can be moved in a direction approaching and separating from the discharge portion of the recording medium. Then, after gripping the leading end of the recording medium to be ejected by the grip means, a space for dropping the recording medium to the accommodating means is formed by moving the grip means in a direction away from the ejecting section. Therefore, the recording medium discharged along with the recording is introduced into the accommodating means by the grip means.

  Also with this configuration, the ejected recording medium can be stored in a stable state, as in the first embodiment. Similarly, there is provided a recording apparatus including a discharge mechanism that can stably store a plurality of discharged recording media without degrading the recording surface of each recording medium even when the recording media are stacked and stored. The Furthermore, according to the first and second embodiments described above, the recording surface of the recording medium is placed on the paper receiving tray 121 so that the recording surface is on the inner side (lower side), so that the recording surface is not rubbed. Therefore, it is possible to eliminate the possibility of image deterioration due to the rubbing of the conventional recording surface. Even when the recorded recording medium is already placed on the paper receiving tray 121, the newly loaded recording medium can be stacked without rubbing. For this reason, even when a plurality of recording media are stacked, occurrence of surface contamination of the recording surface can be prevented.

  In the above embodiment, the serial recording apparatus that forms an image with the recording head 41 mounted on the carriage 40 has been described as an example. However, the present invention uses a long recording head that extends in the width direction of the recording medium, so that a line recording apparatus that records only by one sheet feed (sub-scan) while recording one line at a time, etc. The same applies to other recording methods. In addition, the case of recording on a continuous recording medium (roll paper) wound in a roll shape has been described as an example, but the present invention can also be used when recording on a recording medium of a certain size such as a cut sheet.
