Description

  The present invention relates to a recording apparatus in which a stacker that receives a recorded medium (paper or the like) ejected from the apparatus main body is moved by the power of a power source.

  This type of recording apparatus includes a conveyance unit that conveys a medium such as a sheet and a recording unit that records on the conveyed medium in the apparatus main body. Further, the recording apparatus is provided with a multi-stage stacker (for example, a paper discharge tray) that can be expanded and contracted at a position corresponding to the discharge port of the apparatus main body. Then, the recorded medium is discharged from the discharge port of the apparatus main body and is loaded on the stacker in an extended state.

  2. Description of the Related Art Conventionally, there has been disclosed a recording apparatus in which a multi-stage type discharge tray (stacker) that can be driven to extend and contract by sliding a plurality of trays is expanded and contracted by the power of a power source (motor) (for example, Patent Document 1). In this type of recording apparatus, the length of the paper is compared with the extension amount of the discharge tray. If the extension amount of the discharge tray is not sufficient compared to the length of the paper, the motor is driven, and then the discharge tray is discharged. If the extension amount of the paper tray is sufficient compared to the length of the paper, printing is started. It also has a sensor (discharge tray status detection means) that detects whether the output tray is extended or contracted, and if the sensor detects the extended status of the output tray, printing is performed. On the other hand, a configuration is also disclosed in which printing is prohibited if the sensor detects the contracted state of the paper discharge tray.

  By the way, in the case of a configuration in which a multi-stage stacker is expanded and contracted by the power of a power source, it is necessary to stack a plurality of trays constituting the stacker, so that the stacker tends to be thick. For this reason, there is a problem that a recording apparatus that accommodates a multi-stage stacker tends to be thick in the height direction (vertical direction), and it is difficult to reduce the thickness of the recording apparatus. Further, when a multi-stage stacker is driven by power from a power source, there is a problem that a mechanism for expanding and contracting a plurality of trays is relatively complicated, and the complicated mechanism causes a failure. Therefore, if a single stacker is used, it is relatively easy to reduce the thickness, and the mechanism for moving the stacker back and forth can be a relatively simple structure.

  However, in the case of a single stacker, it is necessary to have a protruding length that can be received even by the maximum paper length when the stacker is protruded. The length becomes relatively long as it does not expand and contract. When the stacker becomes longer in the moving direction, the stacker is inserted deeply into the apparatus main body when the stacker is housed in the apparatus main body, and is inserted and arranged, for example, in an arrangement area for mechanical components in the apparatus main body.

  For example, when the user pushes the paper on the stacker to the back of the main body of the apparatus, or pushes the stacker itself for loading paper to the back of the main body of the apparatus, the paper guides the stacker so that the stacker can move and the medium of the stacker. Enter the depths through the gap with the receiving surface. Then, a part of the paper that has entered from the gap into the back may be sandwiched between the stacker and the guide unit, and the print surface may be rubbed or the sandwiched part may be broken. Further, in the case where the mechanism for driving the stacker is on the medium receiving surface side, the gears or teeth of the mechanism may be bitten and part of the paper may be damaged, or normal driving of the mechanism may be difficult. There is. Furthermore, when another mechanism component exists in the back of the gap, there is a possibility that when a part of the paper enters the arrangement area of the other mechanism component, it is pinched or bitten by another mechanism component. For this reason, it is not practical to use a single stacker because it induces various problems.

  The present invention has been made in view of the above problems, and one of its purposes is to effectively solve the problems caused by the entry of the medium into the gap between the stacker and the guide part, even as a single stacker. An object of the present invention is to provide a recording apparatus that can be avoided.

  In order to achieve one of the above objects, a recording apparatus includes a transport unit that transports a medium, a recording unit that records on the transported medium, and a single stacker having a medium receiving surface that receives the recorded medium. A guide unit that movably guides the stacker, a power source that moves the stacker, a control unit that controls the power source to move the stacker, and charging the recorded medium on the stacker And the charge removing member is provided at a position where the recorded medium on the stacker can be prevented from entering the gap between the medium receiving surface and the guide portion.

  According to the above configuration, since the stacker has a single (single-stage) configuration, the stacker can be made thinner than a multi-stage stacker. Therefore, it is possible to reduce the thickness of the recording apparatus while adopting a configuration in which the stacker is moved by the power of the power source. Further, even if the user presses the recorded medium on the stacker or the stacker itself to the main body of the apparatus by mistake, for example, the medium on the stacker hits the static eliminator, so that the gap between the medium receiving surface of the medium and the guide portion is reached. Can be prevented. In addition, since the static elimination member that removes the charge of the recorded medium on the stacker also serves as a blocking member that prevents the medium from entering the gaps in the medium, the charged charge of the recorded medium can be removed and blocked separately from the static elimination member. There is no need to provide a member. For this reason, the increase in the kind of components and the increase in a number of components can be avoided. Therefore, even if it is a single stacker, it is possible to effectively avoid problems caused by the entry of the medium into the gap between the stacker and the guide portion.

In the recording apparatus, it is preferable that the charge removal member is supported in an oblique posture that is positioned in the medium discharge direction as it approaches the medium receiving surface.
According to the above configuration, since the static elimination member is supported in an oblique posture that is positioned in the medium discharge direction as it approaches the medium receiving surface, when the medium accidentally pressed on the stacker hits the static elimination member, As the medium pushes the charge removal member, the contact pressure between the charge removal member and the medium receiving surface increases. For this reason, the force required to push the static eliminating member until the medium passes through between the static eliminating member and the medium receiving surface is further increased. For this reason, even if the medium is pushed somewhat strongly, the charge removal member can more effectively prevent the medium from entering the gap between the guide portion and the medium receiving surface.

In the recording apparatus, a tip portion of a portion of the static elimination member that contacts and curls the medium receiving surface of the stacker is not separated from the medium receiving surface.
According to the above configuration, since the tip of the portion where the static elimination member contacts and curls the medium receiving surface of the stacker is not separated from the medium receiving surface, the medium that is accidentally pushed on the stacker and the like It is difficult to enter between the receiving surface and the entry of the medium into the gap between the medium receiving surface and the guide portion can be avoided more reliably. For example, if the tip of the curling portion of the static elimination member is lifted from the medium receiving surface, the medium may enter the clearance and the medium may enter as if entering the gap between the static elimination member and the medium receiving surface. . However, since the curled tip does not float from the medium receiving surface, it is possible to avoid the entry of this type of medium.

  The recording apparatus further includes a power transmission mechanism for transmitting the power of the power source to the stacker, and a tooth portion constituting a part of the power transmission mechanism is formed on the medium receiving surface of the stacker. It is preferable that the static eliminating member is in contact with the medium receiving surface while avoiding the tooth portion.

According to the above configuration, since the static elimination member is in contact with the medium receiving surface of the stacker while avoiding the tooth portion, early wear of the static elimination member due to sliding with the tooth portion can be avoided.
The recording apparatus further includes a feeding cassette that is detachably attached to a lower side of the stacker, and a feeding drive unit that feeds a medium from the feeding cassette, and the stacker includes the feeding cassette in a stored state. It is preferable that a concave portion that avoids the driving portion is formed, and the charge removal member is in contact with the stacker in a region that avoids the concave portion in the width direction.

  According to the above configuration, since the static elimination member is in contact with the stacker in a region avoiding the concave portion in the width direction, the static elimination member can be made as small as possible. For example, even if a part of the static elimination member is present in the concave part, the lower side of the part is vacant, and therefore part of the part has no medium entry preventing function. By eliminating this part, the length of disposing the static elimination member in the width direction of the stacker can be relatively shortened.

  In the recording apparatus, a plurality of the charge removal members including two arranged on both sides sandwiching the concave portion in the width direction are provided, and the two charge removal members are assumed to be a medium that is assumed in the width direction of the stacker. It is preferable that they are arranged at an interval narrower than the minimum width.

  According to the above configuration, since the interval in the width direction of the stacker between the two static elimination members is narrower than the assumed minimum width of the medium, even if the minimum width medium is accidentally pushed to the storage direction side on the stacker, etc. However, since the medium with the minimum width does not pass through the gap in the width direction of the two static elimination members, it is possible to prevent the medium with the minimum width from entering the gap between the medium receiving surface and the guide portion.

The operation panel 13 includes a display unit 14 made of a liquid crystal panel or the like and an operation unit 15 made up of a plurality of operation switches. The operation unit 15 includes a power switch 15a for turning on / off the power of the printer 11, a selection switch 15b for selecting and operating a desired selection item on the menu screen displayed on the display unit 14, and the like. It is.

  As shown in FIG. 1, at the lower position of the operation panel 13 on the front surface of the apparatus main body 12, a feeding cassette 16 capable of accommodating a plurality of sheets P as an example of a medium is detachable (can be inserted / removed). It is installed. A plurality of sheets P accommodated in the feeding cassette 16 are sent out one by one from the feeding cassette 16 in order from the top by a pickup roller 17 (see FIG. 3), and the delivered sheets P are transported in a predetermined manner. It is transported in the transport direction Y along the route.

  In the apparatus main body 12, the carriage 18 is guided by a guide shaft 19 that is extended so as to extend in the main scanning direction X that intersects the transport direction Y, and is capable of reciprocating along the main scanning direction X. Is provided. A recording head 20 having a plurality of nozzles for ejecting ink droplets onto the conveyed paper P is attached to the lower portion of the carriage 18. The printed (recorded) paper P is white as shown in FIG. 1 from a discharge port that is exposed when the cover 21 provided on the front surface of the feeding cassette 16 so as to be rotatable about the lower portion is opened. It is discharged in the direction indicated by the pull arrow. An opening / closing type cover 22 is provided at the rear of the apparatus main body 12 so as to close the feeding port through which the paper P can be manually inserted. The cover 22 is opened and the paper P is manually inserted from the feeding port. Printing is also possible.

  As shown in FIG. 2, the apparatus main body 12 is in a state in which a single stacker 23 (medium receiving tray) constituted by a single tray having a substantially square plate shape can enter and exit (retract). State). The stacker 23 is electrically operated, and is in a closed position (retracted position) (for example, the state shown in FIG. 1) housed in the apparatus main body 12 and an open position (for example, the state shown in FIG. 2) protruding from the apparatus main body 12 by a predetermined amount. It is possible to reciprocate between. The operation panel 13 and the stacker 23 are driven by a common power source, and the operation panel 13 rotates forward in conjunction with the protruding operation of the stacker 23 from the closed position so that it is easy to see from the user as shown in FIG. Placed in the posture. At this time, the cover 21 is pushed by the stacker 23 in the middle of protruding from the apparatus main body 12, and the cover 21 is opened against the urging force of a spring (not shown). Then, the printed paper P is discharged onto the stacker 23 in the open position. Even when the stacker 23 is retracted from the open position to the closed position, if the operation panel 13 is once opened to the open position, the operation panel 13 is held in the open position.

  Hereinafter, the components on the paper transport path will be described with reference to FIG. As shown in FIG. 3, the apparatus main body 12 includes a cassette feeding unit 25, a feeding unit 26, a medium transporting unit 27, a recording unit 28, and a feeding unit 29. The cassette feeding unit 25 includes a feeding cassette 16, a pickup roller 17 provided above the feeding cassette 16, and a separation unit provided at a position facing the front end of the paper P stored in the feeding cassette 16. 30.

  The pickup roller 17 is provided at the tip of a swinging member 32 that swings about the swinging shaft 31 and is rotationally driven by the power transmitted from the transport motor 33 (see FIG. 8). The pickup roller 17 rotates in contact with the uppermost sheet P stored in the feeding cassette 16, thereby feeding the uppermost sheet P from the feeding cassette 16 to the feeding path. At this time, the uppermost sheet P sent out by the rotation of the pickup roller 17 from the feeding cassette 16 is separated from the next and subsequent sheets P by the separating unit 30 during the feeding. In this example, the swinging member 32 and the pickup roller 17 constitute an example of a feeding drive unit.

  As shown in FIG. 3, the feeding unit 26 provided on the downstream side of the feeding path of the separation unit 30 includes a feeding driving roller 34 driven by a conveyance motor 33, a separation roller 35, and a feeding driven roller 36. And. The separation roller 35 is in contact with the feed driving roller 34 and again separates the paper P, and reliably feeds only the uppermost paper P to the downstream side of the feed path.

  Further, the sheet P sandwiched between the feeding driving roller 34 and the feeding driven roller 36 is conveyed to the medium conveying unit 27. The medium transport unit 27 includes a transport driving roller 37 that is also driven by the transport motor 33, and a transport driven roller 38 that is driven to rotate in pressure contact with the transport driving roller 37. The medium P is sent further downstream by the medium transport unit 27.

  As shown in FIG. 3, the recording unit 28 provided on the downstream side of the medium conveying unit 27 includes a carriage 18, the recording head 20, and a support base 39 that faces the recording head 20. The recording head 20 provided at the lower portion of the carriage 18 reciprocates in the main scanning direction X (in the direction orthogonal to the paper surface in FIG. 3) while the carriage 18 is guided by the guide shaft 19 by the power of the carriage motor 40 (see FIG. 8). In the process of moving, ink droplets are ejected onto the paper P to print an image on the paper P. At this time, the support base 39 supports the paper P and defines the distance (gap) between the paper P and the recording head 20 to a value suitable for printing.

  The feeding unit 29 provided on the downstream side of the support base 39 includes a first roller 41 driven by the transport motor 33 and a second roller 42 that rotates in contact with the first roller 41. The recorded paper P is sent out by the feeding unit 29 while being sandwiched between the first roller 41 and the second roller 42.

  The printed paper P sent out by the feed unit 29 is discharged onto the stacker 23 indicated by a two-dot chain line in FIG. The stacker 23 is configured such that its slide direction can be switched to a state where it is pulled out along the Y direction or a state where it is pulled inside the apparatus main body 12. At least during printing, the stacker 23 slides and protrudes in the direction toward the outside of the apparatus main body 12 with the rotation of the operation panel 13 with respect to the apparatus main body 12.

  Further, in the present embodiment, printing on the manually inserted paper P is performed by inserting the paper P (indicated by a two-dot chain line in FIG. 3) from the feeding port 43 exposed with the manual feed cover 22 opened. Is also possible. In the present embodiment, the feeding unit 26, the medium transporting unit 27, the feeding unit 29, the transporting motor 33, and the power transmission switching unit 81 interposed between the transporting motor 33 and the units 26, 27, 29 (FIG. 8). Reference) constitutes an example of the transport unit.

  As shown in FIG. 3, the stacker 23 includes a base part 23 b that bulges upward while forming an inclined guide surface 23 a that inclines so that the front end part in the transport direction Y becomes higher toward the front end side, and the width of the base part 23 b A pair of raised portions 23c are formed adjacent to both sides in the direction (same as the main scanning direction X) and rise higher than the base portion 23b. In addition, the stacker 23 is formed with a square plate shape (see FIG. 4) in a substrate portion 23d excluding the tip portion. The plate-like frame 44 disposed below the support base 39 and the plate-like support plate portion 45 disposed below the plate-like frame 44 at a predetermined interval in the vertical direction with respect to the frame 44 A guide portion 46 capable of accommodating the substrate portion 23d is formed. The stacker 23 is placed in a closed position indicated by a solid line in FIG. 3 when the substrate portion 23d is deeply inserted into the guide portion 46, and protrudes from the closed position (retracted position) with respect to the apparatus main body 12. Is moved to the open position indicated by the two-dot chain line in FIG.

  The printer 11 of the present embodiment has a label printing function for storage disks such as CDR and DVD, and the storage disk extends along the slit between the base portion 23 b and the raised portion 23 c of the stacker 23, and the medium transport portion 27. In addition, insertion is guided up to the feeding portion 29. For this reason, the stacker 23 of the present example has a shape in which the tip portion protrudes upward, but the stacker 23 may be formed in a flat plate shape that does not have a guide function of the storage disk. Further, the output amount from the closed position of the stacker 23 may be controlled according to the length of each paper P to be printed.

  Further, as shown in FIG. 3, in the printer 11, the operation panel 13 when in the closed position adopts a layout in which the operation panel 13 is located on the movement path when the stacker 23 moves from the closed position to the open position. The main body 12 is reduced in thickness. In order to project the stacker 23 from the closed position shown in FIG. 3, the operation panel 13 is first opened, the operation panel 13 is retracted from the movement path of the stacker 23, and then the stacker 23 is projected.

  Here, the components of the stacker 23 will be described with reference to FIG. The stacker 23 includes a medium receiving surface 48 on which the received paper P is placed on the upper surface of the substrate portion 23d. At both ends in the width direction of the medium receiving surface 48, a pair of racks 49, 49 extending along the stacker moving direction (same as the paper discharge direction Y) are provided. The racks 49, 49 are a pair of pinion gears fitted to a rotary shaft 52 constituting a power transmission mechanism 51 to which power of an electric motor 50 as an example of a power source is transmitted with a predetermined interval in the axial direction. 53 and 53 are meshed with each other.

  The stacker 23 moves from the closed position to the open position or moves from the open position to the closed position by the power transmitted from the electric motor 50 via the power transmission mechanism 51. In the present embodiment, when the electric motor 50 is driven forward, the stacker 23 moves in the protruding direction from the closed position toward the open position, and when the electric motor 50 is driven reversely, the stacker 23 is moved from the open position to the closed position. Move toward the stowed direction. Of course, the stacker 23 can be configured so that only the protruding operation of moving from the closed position to the open position is automatically performed by the power of the electric motor 50, and the storage from the open position to the closed position is manually performed by the user.

  Further, as shown in FIG. 4, the apparatus main body 12 is provided with a closing sensor 55 that detects a state in which the stacker 23 is in the closed position and an open sensor 56 that detects a state in which the stacker 23 is in the open position. Yes. The closing sensor 55 detects that the stacker 23 is in the closed position by detecting a detected portion 57 formed on the upper surface of one raised portion 23c of the stacker 23. The open sensor 56 detects that the stacker 23 is in the open position by detecting a notch recess 23e formed in the rear end of the stacker 23 when the stacker 23 is in the open position.

  Further, as shown in FIG. 4, the width direction central portion of the rear portion of the substrate portion 23d (the left portion in FIG. 4 and the upstream portion in the paper discharge direction Y) is directed from the upstream side in the discharge direction Y toward the downstream side. A recess 23f that is recessed is formed. The stacker 23 is accommodated in the closed position while avoiding the swinging member 32 (see FIG. 3) supporting the pickup roller 17 by the recess 23f. For this reason, the stacker 23 can be inserted to a deep position in the apparatus main body 12 in the closed position. Therefore, although the stacker 23 has a single tray structure, its length in the moving direction is relatively long, so that a required amount of protrusion is ensured when protruding from the apparatus main body 12. Further, since the stacker 23 has a single tray structure, it can secure a certain thickness and has a relatively high rigidity.

  As shown in FIG. 4, the electric motor 50 is provided with a rotary encoder 58 that outputs a detection pulse signal having a number of pulses proportional to the rotation amount. In the printer 11, the output amount of the stacker 23 is obtained by counting, for example, the pulse edges of the detection pulse signal from the rotary encoder 58 with a counter when the close sensor 55 detects that the stacker 23 is in the closed position. Is measured.

  As shown in FIG. 4, the gear 60 fitted to the rotating shaft of the electric motor 50 is transmitted to the gear 62 via the gear 61. A gear train 63 from the gear 62 to the lower gears 63 a to 63 g serves as a driving force transmission path to the stacker 23. Only a part of the power transmission mechanism 51 in FIG. 4 that transmits power from the electric motor 50 to the stacker 23 is shown, and power is transmitted to the operation panel 13 by another part (not shown). In the present embodiment, the operation panel 13 is rotated in the upward opening direction by the driving force of the electric motor 50. However, when the operation panel 13 is rotated to the open position, the power transmission mechanism 51 has power to the operation panel 13. A release mechanism for releasing the transmission is included, and when the operation panel 13 is closed, the user pushes down the operation panel 13. The stacker 23 has a specification in which both the protruding operation and the storing operation are automatically performed by the power of the electric motor 50. However, the stacker 23 can be slid in both directions by a user operation. Of course, it is also possible to adopt a configuration in which the power transmission mechanism 51 is only shown in FIG. 4 and the electric motor 50 transmits the power only to the stacker 23.

  As shown in FIG. 4, a plurality of ridges 23 g (for example, ribs) extending along the discharge direction Y are formed to protrude in the center region in the width direction on the medium receiving surface 48 of the stacker 23. Since the paper P discharged to the stacker 23 is placed on the medium receiving surface 48 while sliding with the upper end surfaces of the plurality of ridges 23g, the paper P and the medium receiving when discharged onto the stacker 23 are placed. The sliding resistance with the surface 48 is reduced. The medium receiving surface 48 is formed with a pair of concave portions 23h at both side positions sandwiching a plurality of convex strips 23g in the width direction. Specifically, the pair of recesses 23h is formed by a pair of small-size (for example, L plate or 2L plate) photo paper discharged on the medium receiving surface 48 and both ends in the width direction of a relatively narrow paper P such as a postcard. Is formed at a position on the medium receiving surface 48 such that it is in each of the recesses 23h. For this reason, both ends in the width direction of the small-sized paper P placed on the medium receiving surface 48 are in a state of floating from the bottom surface of the recess 23h, and the user grips the floating portion of the paper P, Even small-size paper P can be removed from the stacker 23 relatively easily.

  As shown in FIGS. 4 and 5, in this embodiment, a pair of neutralizing cloths 47 as an example of a neutralizing member are disposed in the apparatus main body 12 above the stacker 23 in the width direction of the medium receiving surface 48. A pair (two) is provided in contact with each of two regions sandwiched between the rack 49 and the recess 23f.

  A gate-shaped main body frame 66 as shown in FIG. 5 is arranged in the apparatus main body 12 so as to surround the paper conveyance space, the storage space of the feeding cassette 16, the storage space of the stacker 23, and the like. The main body frame 66 includes a pair of base portions 66a disposed on both sides sandwiching the housing recess 12a in which the feeding cassette 16 is housed in the width direction, and a bridge supported in an erected state on each upper end portion of the pair of base portions 66a. Part 66b.

  As shown in FIG. 5, the rollers 41 and 42 that constitute the feeding portion 29, the rotating shaft 52, and the like are pivotally supported on the pair of base portions 66 a. Below the first roller 41 and the rotary shaft 52, a plate-like frame 44 extends from the main body frame 66 along the transport direction Y in a substantially horizontal state to the front in a range extending over the entire width direction of the medium discharge region. I'm out. The pair of neutralizing cloths 47 are in contact with the two regions corresponding to the space between the pair of racks 49 and the recesses 23f with respect to the medium receiving surface 48 of the stacker 23 at the lower ends (tips).

  As shown in FIG. 5, the guide portion 46 for inserting and guiding the substrate portion 23d of the stacker 23 guides the above-described plate-like frame 44 facing the upper surface of the substrate portion 23d and both end surfaces in the width direction of the substrate portion 23d. It is formed by the side guide portion 67a and the support plate portion 45 that supports the lower surface of the substrate portion 23d, and has a flat cylindrical shape elongated in the width direction.

  The support plate portion 45 is a substantially square plate-like member having an area capable of supporting almost the entire bottom surface of the substrate portion 23d of the stacker 23, and is slightly larger than the thickness of the substrate portion 23d in the vertical direction with respect to the lower surface of the frame 44. It is arranged in a horizontal state at a lower position with a wide predetermined interval. The space below the support plate 45 is an accommodation recess 12a in which the feeding cassette 16 is accommodated. The side guide portion 67a is formed by a portion in which a resin frame portion 67 disposed in the pair of left and right base portions 66a extends horizontally inward in the width direction.

  Further, as shown in FIG. 5, the main body frame 66 has a U-shaped cross section that extends in the main scanning direction X at a position above the first and second rollers 41 and 42 constituting the feeding portion 29. The bridge portion 66b is provided, and the electric motor 50 is disposed in the bridge portion 66b. The power of the electric motor 50 is transmitted as the rotational force of the rotating shaft 52 via the power transmission mechanism 51 disposed in the left base 66a in FIG. The two pinion gears 53 respectively provided at two positions spaced apart from each other by a predetermined distance in the axial direction of the rotating shaft 52 rotate while meshing with the rack 49 on the stacker 23, so that the stacker 23 is connected to the electric motor 50. According to the reverse rotation, it moves in and out in a direction parallel to the discharge direction Y.

  By the way, in order to attach the stacker 23 to the guide portion 46 so as to be movable, a certain amount of gap (a value within a range of 0.1 to 2 mm as an example) is required between the stacker 23 and the guide portion 46. If the user accidentally pushes the printed paper P placed on the stacker 23 toward the apparatus main body 12, the paper P pushed to the back of the paper P is a gap G between the guide portion 46 and the medium receiving surface 48 ( There is a risk of entering from the back to the back. When the stacker 23 is stored manually or electrically in a state where a part (rear end portion) of the sheet P enters the interior of the guide portion 46 from the gap G, the sheet P is moved between the stacker 23 and the guide portion 46. There is a risk that the paper P may be folded between the gaps, or the paper P may be jammed between the pinion gear 53 and the rack 49 and jammed. In addition, when entering the arrangement area of another mechanism component (for example, a feeding mechanism including the swinging member 32 and the pickup roller 17) in the back of the gap G, it is sandwiched or bitten by another mechanism component. There is also a risk that.

  Therefore, in this embodiment, as shown in FIGS. 4 and 5, the neutralizing cloth 47 that prevents the paper P on the stacker 23 from entering the gap G contacts the medium receiving surface 48 at the upper position of the stacker 23. It is attached in the state to do. As shown in FIGS. 3 and 5, the pair of neutralizing cloths 47 are fixed to the front end portion on the downstream side in the transport direction Y of the frame 44 constituting the guide portion 46. As shown in FIG. 5, the pair of neutralizing cloths 47 are in contact with the medium receiving surface 48 in two regions between the pair of racks 49 and the recesses 23f in the width direction. The interval in the main scanning direction X of the pair of charge removal cloths 47 is set to be shorter than the width of the minimum size paper Pmin (minimum paper) in the main scanning direction X. This is to prevent the paper Pmin having the minimum size from entering the inner portion of the guide portion 46 through the gap between the pair of neutralizing cloths 47. Moreover, since the disposition of the neutralizing cloth 47 is avoided from the position corresponding to the rack 49, it is possible to prevent the neutralizing cloth 47 from being worn by sliding with the teeth of the rack 49 and shortening its life. Of course, a wide static elimination cloth 47 in the main scanning direction X may be arranged.

Next, the attachment structure of the static elimination cloth 47 is demonstrated using FIG.
As shown in FIG. 6, the neutralizing cloth 47 is fixed to the front surface (surface on the downstream side in the Y direction) of the support portion 44 a formed at the downstream end portion in the discharge direction Y direction of the frame 44 constituting the guide portion 46. . The front surface of the support portion 44a is formed on a slope 44b that is inclined downward so as to be positioned downstream of the medium receiving surface 48 in the discharge direction Y. The neutralizing cloth 47 is arranged in such a posture that it is inclined downward so as to be positioned on the downstream side in the discharge direction Y as it approaches the medium receiving surface 48 by fixing the base portion to the inclined surface 44b. The base portion of the static eliminating cloth 47 is fixed to the inclined surface 44b via an adhesive portion 68 such as an adhesive or a double-sided adhesive tape.

  As shown in FIG. 6, the static elimination cloth 47 has a length that comes into contact with the upper surface of the base portion of the stacker 23 and bends in a curved shape. The tip portion of the neutralizing cloth 47 is deformed so as to be in contact with the medium receiving surface 48 at an angle and curl downstream in the transport direction. The neutralizing cloth 47 is adjusted to a length that is not so long that the leading end of the portion to be curled rises from the medium receiving surface 48 although the leading end of the neutralizing cloth 47 comes into contact with the medium receiving surface 48 and bends in a curl shape. Here, the curling method when the tip of the neutralizing cloth 47 comes into contact with the medium receiving surface 48 is affected by the hardness (softness) of the neutralizing cloth 47, so that it contacts the medium receiving surface 48 of the neutralizing cloth 47. Thus, the length of the curled portion is adjusted according to the hardness of the neutralizing cloth 47 so that the tip of the curled portion is not separated from the medium receiving surface 48.

Next, the electrical configuration of the printer 11 will be described with reference to FIG.
As shown in FIG. 8, the printer 11 includes a controller 70 as an example of a control unit that performs various controls. The controller 70 is communicably connected to the host device 100 via the communication interface 71. The controller 70 controls the printing operation of the printer 11 based on the print job data received from the host device 100. The host device 100 is composed of, for example, a personal computer or a mobile phone, and incorporates a printer driver 101. The host device 100 includes an input unit 102 including a keyboard and a mouse, and a user operates the input unit 102 to set print conditions and execute printing. The printer driver 101 generates print image data based on the printing conditions, and sends the generated print job data with a header to the printer 11.

  A display unit 14, a carriage motor 40, a transport motor 33, and an electric motor 50 are connected to the controller 70 as an output system. The controller 70 is connected with an operation unit 15 including a power switch 15a, a linear encoder 72, rotary encoders 58 and 73, a paper detection sensor 74, a close sensor 55, an open sensor 56, and a medium presence / absence sensor 69 as an input system. ing.

  As shown in FIG. 8, the controller 70 includes a computer 75, a display driver 76, a head driver 77, and motor drivers 78, 79, and 80. The computer 75 drives the recording head 20 via the head driver 77 based on the print job data, and draws an image or the like based on the print image data by ejecting ink droplets. Further, the computer 75 drives and controls the carriage motor 40 via the motor driver 78 and controls the movement of the carriage 18 in the main scanning direction X. At this time, the computer 75 counts the input pulses from the linear encoder 72 with a counter (not shown), thereby grasping the movement position of the carriage 18 with the home position as the origin, for example.

  Further, the computer 75 drives the transport motor 33 via the motor driver 79. Here, a power transmission switching portion 81 having a switching lever (not shown) disposed on the movement path of the carriage 18 is interposed on the power transmission path of the transport motor 33. The power transmission switching unit 81 is switched to a switching position corresponding to the rotational position when the transport motor 33 is driven by a predetermined amount of rotation while the carriage 18 pushes the switching lever. The transport motor 33 is always connected to the feeding drive roller 34, the transport drive roller 37, and the first roller 41. At one switching position among the plurality of switching positions of the power transmission switching unit 81, the power transmission is connected to the pickup roller 17 so that power can be transmitted.

  Further, as shown in FIG. 8, the computer 75 drives the electric motor 50 via the motor driver 80. When the electric motor 50 is driven to rotate in the forward direction, the pinion gear 53 rotates in the forward direction, and the stacker 23 moves in the protruding direction through the meshing of the forwardly rotating pinion gear 53 and the rack 49. On the other hand, when the electric motor 50 is driven to rotate in the reverse direction, the pinion gear 53 rotates in the reverse direction, and the stacker 23 moves in the storage direction through the meshing of the pinion gear 53 and the rack 49 that rotate in reverse.

  The close sensor 55 is turned on when the stacker 23 is in the closed position, and is turned off when the stacker 23 is not in the closed position. Further, the open sensor 56 is turned on when the stacker 23 is in the open position of the maximum output amount, and is turned off when the stacker 23 is not in the open position. The encoder 58 outputs a detection pulse signal having a number of pulses proportional to the amount of rotation of the electric motor 50. The computer 75 includes a counter (not shown) whose origin is when the closing sensor 55 detects that the stacker 23 is in the closed position. The computer 75 increments the counter when the moving direction of the stacker 23 obtained by comparing the phases of the two signals having different phases included in the detection pulse signal from the encoder 58 is the protruding direction, When the moving direction of 23 is the storing direction, the counter is decremented. In this way, the computer 75 grasps the position corresponding to the actual output amount of the stacker 23 from the count value of this counter.

  The medium presence sensor 69 detects the presence or absence of the paper P (medium) on the stacker 23. The computer 75 of this embodiment performs control to pull back the stacker 23 in the storing direction if there is no next print job even after a predetermined time (for example, a value within a range of 10 seconds to 10 minutes) has elapsed after the print job is completed. . At this time, the computer 75 determines the presence / absence of the paper P on the stacker 23 based on the detection result of the medium presence / absence sensor 69. While the paper P is on the stacker 23, the computer 75 does not store the stacker 23 and the user picks up the printed matter. When the paper P is removed from the stacker 23, the stacker 23 is stored. For example, even if the printed material is forgotten, the stacker 23 is not stored, so that the printed material can be prevented from dropping from the stacker due to the storage operation of the stacker 23. Of course, the stacker 23 may not be stored regardless of the presence or absence of the paper P on the stacker 23, and the stacker 23 may be stored manually by the user. In this case, the medium presence / absence sensor 69 is used to notify the host apparatus 100 to urge removal of the printed matter on the stacker 23 when the paper P remains on the stacker 23 for a certain time. Of course, in the case of a configuration in which the stacker 23 is manually stored by the user, the medium presence sensor 69 may be eliminated.

  The linear encoder 72 outputs a detection pulse signal having a number of pulses proportional to the amount of movement of the carriage 18. The computer 75 counts the pulse edge of the detection pulse signal from the linear encoder 72 with a counter (not shown) with the origin when the carriage 18 is at the home position, and the main scanning direction of the carriage 18 from the counted value. Know the position at X. The encoder 73 outputs a detection pulse signal having a number of pulses proportional to the rotation amount of the transport motor 33. The computer 75 counts the pulse edge of the detection pulse signal from the encoder 73 with a counter (not shown) based on the time when the paper detection sensor 74 detects the leading edge or the trailing edge of the paper P. From this, the conveyance position of the paper P is grasped. The computer 75 controls the ink ejection timing of the recording head 20 according to the position of the carriage 18 in the main scanning direction X, and also controls the transport motor 33 according to the transport position of the paper P, so Place it at the print position.

  A computer 75 shown in FIG. 8 includes, for example, a CPU 82, an ASIC 83 (Application Specific IC), a nonvolatile memory 84, a RAM 85, and the like. The nonvolatile memory 84 stores various programs including a stacker control program. Further, the RAM 85 stores print job data and stores the calculation results by the computer 75. The computer 75 implements various functions including a stacker control function by executing a program read from the nonvolatile memory 84 by the CPU 82. Of course, the main control unit of the controller 70 is not limited to a software configuration using the computer 75, but may be a hardware configuration such as an electronic circuit (for example, a custom IC) or a configuration based on cooperation between software and hardware. Good.

Next, the operation of the printer 11 configured as described above will be described.
When the print job data is received, the controller 70 drives the electric motor 50 to move the stacker 23 in the protruding direction from the closed position and arrange it in the open position. At this time, the operation panel 13 using the electric motor 50 as a common power source rotates from the closed position to the open position. After the operation panel 13 is rotated to a position where it does not interfere with the stacker 23, the stacker 23 moves to an open position in the protruding direction without interfering with the operation panel 13. Note that the controller 70 may control the output amount of the stacker 23 according to the sheet length acquired from the print condition information in the header of the print job.

  Next, a paper feeding operation is performed. The controller 70 drives the transport motor 33 to rotationally drive the pickup roller 17 to feed the uppermost sheet P in the feeding cassette 16 to the downstream side in the feeding direction. It is transported to the print start position by a route passing through the outer periphery. Then, a printing operation for printing on the paper P fed to the printing start position is performed. The printing operation is performed by substantially alternately performing printing for one pass performed by moving the carriage 18 once in the main scanning direction X and paper feeding for transporting the paper P to the next printing position.

  When printing based on the print job is completed, a paper discharge operation is performed. That is, the controller 70 drives the transport motor 33, and discharges the paper P by rotating and driving the rollers 34, 37, 41, and the like. As a result, the printed paper P is discharged onto the stacker 23.

  For example, when the user accidentally presses the paper P discharged onto the stacker 23 by hand, the paper P moves to the back of the apparatus main body 12 along the medium receiving surface 48. However, as shown in FIG. 7, the sheet P hits the static elimination cloth 47 and is prevented from entering the gap G between the guide portion 46 and the medium receiving surface 48 of the sheet P. Similarly, when the user accidentally pushes the stacker 23 in the storing direction, the paper P on the stacker 23 hits the static eliminator 47 as shown in FIG. 7, so that the paper P is prevented from entering the gap G. The Furthermore, since the interval in the width direction of the two static elimination cloths 47 is narrower than the assumed minimum width of the paper, even if the paper Pmin has the minimum width, the static elimination cloth 47 is prevented from entering the gap G. Further, in this embodiment, since the neutralizing cloth 47 is used as a blocking member for blocking the entry of the paper into the gap G, the stacker 23 is added to the function of preventing the paper P from entering the gap G. The static electricity charged on the paper P stacked thereon can be removed by the neutralizing cloth 47.

According to the first embodiment described in detail above, the following effects can be obtained.
(1) Since the single stacker 23 is automatically withdrawn / retracted, the stacker 23 is automatically moved from the closed position to the open position and printed even when the host apparatus 100 is operated from a remote location to perform remote printing. The paper P discharged in this manner can be received by the stacker 23. Since the stacker 23 has a single configuration, the thickness of the stacker 23 can be reduced compared to a multi-stage stacker. Therefore, it is possible to reduce the thickness of the printer 11 while adopting a method in which the stacker 23 is automatically moved by the power of the electric motor 50. Moreover, since the stacker 23 is a single sheet, it is possible to obtain higher rigidity than a multi-stage stacker.

  (2) A neutralizing cloth 47 is provided as a blocking member that prevents the paper P on the stacker 23 from entering the gap G between the guide portion 46 and the medium receiving surface 48. For this reason, even if the user accidentally pushes the paper P discharged on the stacker 23 or the stacker 23 itself by hand, and the paper P moves to the back of the apparatus main body 12, the paper P hits the static elimination cloth 47. The sheet P is prevented from entering the gap G. For this reason, when at least a part of the paper enters the gap G, the paper P is sandwiched between the stacker 23 and the guide portion 46, the printing surface is rubbed, the paper P is bent, the pinion gear 53 and the rack. It is possible to effectively avoid defects such as scratches and tearing of the paper P caused by the biting of the paper P between the 49 and the stacker 23 caused by the bited paper piece being difficult to drive smoothly. In particular, since the tip of the relatively soft charge-removing cloth 47 comes into contact with the medium receiving surface 48, even paper P, such as plain paper, which is thinner and relatively softer than photographic paper, can enter the gap G. Can be effectively blocked.

  (3) Since the neutralizing cloth 47 is used as a blocking member for blocking the paper P from entering the gap G, the sheet P stacked on the stacker 23 is added to the function of preventing the paper P from entering the gap G. Can remove charged static electricity. For this reason, it is easy to suppress the increase in the types and the number of parts as compared with a configuration in which a member dedicated to preventing the paper P from entering the gap G is provided separately from the static elimination cloth.

  (4) The static eliminating cloth 47 is supported in an inclined posture so that the base portion is fixed to the inclined surface 44b, and the discharge cloth Y is positioned downstream in the discharge direction Y as it approaches the medium receiving surface 48. Therefore, even if the paper P that is accidentally pressed on the stacker 23 tries to push the static elimination cloth 47 upstream in the discharge direction Y, the contact pressure between the static elimination cloth 47 and the medium receiving surface 48 increases as the push is pushed. The large load can effectively prevent the paper P from proceeding to the gap G.

  (5) Since the tip of the portion where the neutralizing cloth 47 contacts the medium receiving surface 48 and curls is not separated from the medium receiving surface 48, the paper P that is accidentally pressed on the stacker 23 is It is possible to avoid entering the gap G by entering the gap between the leading end portion lifted from the medium receiving surface 48 and the medium receiving surface 48.

  (6) Since the neutralizing cloth 47 is in contact with the medium receiving surface 48 avoiding the rack 49 (tooth portion) extending along the stacker moving direction, it is caused by early wear of the neutralizing cloth 47 due to sliding with the rack 49. This can avoid shortening the service life of parts.

  (7) The neutralizing cloth 47 includes a pair of racks formed at both ends in the width direction of the recess 23f formed in the stacker 23 and the medium receiving surface 48 in order to avoid the swing member 32 when the stacker 23 is stored. 49 is in contact with the medium receiving surface 48 in two regions. For this reason, early wear due to sliding of the static elimination cloth 47 with the rack 49 can be avoided, and the length of the static elimination cloth 47 in the stacker width direction can be shortened as much as possible.

  (8) The two static elimination cloths 47 are arranged in the stacker width direction with an interval narrower than the assumed minimum width of the paper. For this reason, even if the minimum width paper Pmin is accidentally pushed to the storage direction side on the stacker 23, the minimum width paper Pmin hits the two static elimination cloths 47, so that the gap G of the paper Pmin is reached. Can be prevented.

  (9) Since the operation panel 13 rotates from the closed position to the open position in conjunction with the movement of the stacker 23 from the closed position to the open position, the operation panel 13 opens the stacker 23 without blocking the path of the stacker 23. It can be moved to a position. For this reason, by adopting a layout in which the operation panel 13 in the closed position is positioned on the movement path of the stacker 23, the printer 11 can be thinned while securing the movement path of the stacker 23.

  (10) A concave portion 23 f is formed at a position corresponding to the swing member 32 in the base portion (rear portion) of the stacker 23. For this reason, the stacker 23 can be inserted deeply into the apparatus main body 12 in the direction opposite to the transport direction Y without interfering with other members such as the swinging member 32. For this reason, even if the stacker 23 has a single tray structure, it is possible to sufficiently secure the protruding length necessary for receiving the paper P when the stacker 23 protrudes.

In addition, the said embodiment can also be changed into the following forms.
-The guide part does not need to be substantially cylindrical. A rail or a guide plate that guides at least one of the side portion and the bottom portion of the stacker 23 may be used. The rack and pinion mechanism may be provided on the side or bottom of the stacker 23. Even with these configurations, it is possible to avoid problems such as the sheet being folded between the stacker 23 and the guide portion at the back.

  -The static elimination cloth is not limited to the structure attached to the component of the guide part 46, You may attach to the frame part other than the guide part 46, the support stand 39, and the other member arrange | positioned above the stacker 23. .

  -Although the neutralization cloth was provided in one place in the discharge direction Y, it may be provided in a plurality of places. According to this configuration, even if the paper exceeds the first static elimination cloth, it can be prevented by the next static elimination cloth, so that the insertion of the paper into the gap G in the guide portion 46 can be more reliably prevented.

  -It is not limited to providing two static elimination cloths in the width direction, and three, four, or five or more may be provided. For example, two may be provided on both sides of the recess 23f in the width direction. Moreover, it is good also as one static elimination cloth. In this case, for example, one static elimination cloth may be provided in a length over almost the entire region in the width direction of the stacker 23.

  If the pick-up roller 17 is not a center feeding method in which the pickup roller 17 is disposed at a substantially central position in the width direction of the feeding cassette 16 but a one-sided feeding method in which the feeding unit is moved to one end in the width direction, the minimum size paper It is preferable to dispose a charge removal member (for example, a charge removal cloth) at the end position near the feeding section so as to prevent entry into the gap G.

  The neutralizing cloth 47 may be provided on the medium receiving surface 48 of the stacker 23 in a non-contact state. If it is of a type that can be neutralized without contact, neutralization is possible. If the gap with the medium receiving surface 48 is narrower than the sheet thickness, the sheet gap G can be obtained by using a neutralizing cloth with a certain degree of hardness. Can be inserted into the.

  The neutralizing member is not limited to the neutralizing cloth 47. As long as it has a charge removal function, the charge removal member may be a rubber piece (for example, a rubber sheet piece), a resin piece (for example, a resin sheet piece), a brush, or the like. In this case, it is preferable that the static elimination member has flexibility. Moreover, when providing a some static elimination member, you may combine a different kind of static elimination member.

  The power source of the stacker 23 and the operation panel 13 may be different. Further, the power source of the stacker 23 may be a common transport motor for the transport unit. In this case, the power transmission destination of the conveyance motor 33 may be switched to the stacker 23 by the power transmission switching unit 81.

  -As long as the stacker 23 is one sheet, it is not necessarily limited to one tray structure. For example, if it is a single sheet, it may be a box-shaped structure consisting of a box whose upper side is opened or a shaft-type structure that receives a medium by arranging a plurality of axes in parallel.

  The mechanism for transmitting power to the stacker 23 is not limited to the rack and pinion mechanism. For example, the stacker 23 is fixed to an endless belt wound around a pair of pulleys arranged at a predetermined distance along the transport direction Y, and the stacker is rotated forward and backward by the power of the power source. A belt driving system in which 23 is withdrawn and withdrawn may be used.

-The power source is not limited to a rotary motor, and may be a linear motor.
The medium is not limited to paper, and may be a resin film, a metal foil, a metal film, a resin-metal composite film (laminate film), a woven fabric, a nonwoven fabric, a ceramic sheet, or the like.

  The recording apparatus is not limited to the ink jet type, and may be a dot impact type or a laser type. Furthermore, the recording apparatus is not limited to a serial printer, and may be a line printer or a page printer.

The recording apparatus only needs to have at least a recording function (printing function) for forming an image on a medium. For example, the recording apparatus may be a multifunction machine having a printing function, a scanner function, and a copying function.
In the above-described embodiment, the recording apparatus is embodied as an ink jet printer that is one of the liquid ejecting apparatuses. However, when applied to the liquid ejecting apparatus, the recording apparatus is not limited to the printer, and other liquids (functional materials) other than ink. In other words, the present invention can be embodied in a liquid ejecting apparatus that ejects or ejects a liquid material obtained by dispersing or mixing particles in a liquid or a fluid material such as a gel. For example, a liquid material that contains materials such as electrode materials and color materials (pixel materials) used in the manufacture of liquid crystal displays, EL (electroluminescence) displays, and surface-emitting displays in a dispersed or dissolved form is used as an example of a medium. A recording apparatus that sprays onto a sheet-like substrate may also be used. If the stacker is configured to automatically appear and disappear, the sheet-like substrate can be received and the stacker 23 is composed of a single tray. Therefore, the liquid ejecting apparatus is more liquid than a liquid ejecting apparatus having a multi-stage stacker. The device can be made thinner. As described above, the medium (recording medium) may be a substrate on which elements, wirings, and the like are formed by inkjet. The “liquid” ejected by the liquid ejecting apparatus includes a liquid (including an inorganic solvent, an organic solvent, a solution, a liquid resin, a liquid metal (metal melt), etc.), a liquid, a fluid, and the like.
