Field of the Invention
The present invention relates to a discharge apparatus configured to discharge a recording medium and a detachable tray.
Description of the Related Art
Japanese Patent Application laid-open No. 2001-225963 describes an electrophotographic recording apparatus including a printer body by which an image is printed on a paper sheet fed from a feed unit and a discharge unit on which the paper sheet discharged from the printer body is supported. The discharge unit of such an electrophotographic recording apparatus includes rear guides each of which has a plate-like body extending perpendicularly and a stacking plate which is disposed between the rear guides to support the paper sheet discharged from the printer body. The paper sheet discharged from a discharge port of the printer body is guided by the rear guides, and then it is stacked on the stacking plate disposed below the discharge port while the movement of the paper sheet in a width direction is regulated.
In the technology disclosed in Japanese Patent Application laid-open No. 2001-225963, each paper sheet discharged from the discharge port is aligned by the bodies of the rear guides and then stacked on the stacking plate. To improve the paper aligning property on the stacking plate, the distance between the bodies of the rear guides should not be too large as compared with the paper width. However, if the distance between the bodies of the rear guides is short, a paper sheet discharged from the discharge port with skew may get jammed. Meanwhile, if the distance between the bodies of the rear guides is considerably larger than the paper width, the stacked positions of paper sheets are more likely to vary in the width direction.
An object of the present teaching is to provide a discharge apparatus and a detachable tray which are capable of improving the aligning property of a recording medium while preventing the recording medium discharged from a discharge port with skew from getting jammed between guide members.
According to a first aspect of the present teaching, there is provided a discharge apparatus, including:
a discharge mechanism including a discharge port and configured to discharge a recording medium from the discharge port in a first direction;
a receiving member having a receiving surface which receives the recording medium discharged from the discharge port;
an abutting member having an abutting surface which abuts against an upstream end or a downstream end in the first direction of the recording medium received by the receiving surface;
guide members extending upward beyond the receiving surface and configured to guide the recording medium, which is discharged from the discharge port to fall toward the receiving surface, from both sides in a second direction orthogonal to the first direction and parallel to the receiving surface;
wherein the guide members respectively include protruding portions protruding inward in the second direction and extending in a longitudinal direction of the guide members, and
the guide members are disposed at positions where leading ends of the protruding portions make contact with both sides in the second direction of the recording medium which is discharged from the discharge port to fall toward the receiving surface.
The discharge apparatus according to the first aspect of the present teaching includes the guide members having the protruding portions respectively. This improves the aligning property of the recording medium while preventing the recording medium discharged from the discharge port with skew from getting jammed between the guide members, without greatly lengthening the distance between the guide members (the leading ends of the protruding portions) relative to the width of the recording medium.
According to a second aspect of the present teaching, there is provided a detachable tray to be installed to a receiving tray of a discharge apparatus, the discharge apparatus including: a discharge mechanism including a discharge port and configured to discharge a recording medium from the discharge port in first direction; and the receiving tray configured to receive the recording medium discharged from the discharge port, the detachable tray including:
a receiving member disposed on the receiving tray and having a receiving surface which receives the recording medium discharged from the discharge port; and
guide members extending upward beyond the receiving surface and configured to guide the recording medium, which is discharged from the discharge port to fall toward the receiving surface, from both sides in a second direction orthogonal to the first direction and parallel to the receiving surface,
wherein the guide members respectively include protruding portions protruding inward in the second direction and extending in a longitudinal direction of the guide members, and
the guide members are disposed at positions where leading ends of the protruding portions make contact with both sides in the second direction of the recording medium which is discharged from the discharge port to fall toward the receiving surface.
The detachable tray according to the second aspect of the present teaching includes the guide members having the protruding portions respectively. This improves the aligning property of the recording medium while preventing the recording medium discharged from the discharge port with skew from getting jammed between the guide members, without greatly lengthening the distance between the guide members (the leading ends of the protruding portions) relative to the width of the recording medium.

The heads 110a and 110b, which have the same structure, are formed in an approximately rectangular parallelepiped shape which is long in the main scanning direction D2. Namely, the printer 100 is a line-type ink-jet printer. Each of the heads 110a and 110b includes a channel unit in which channels with pressure chambers are formed and an actuator which applies pressure to the liquid (the pretreatment liquid or the ink) of each pressure chamber. The bottom surface of the channel unit is a jetting surface 110x with jetting ports from which the pretreatment liquid or the ink is jetted. The pretreatment liquid is supplied from a cartridge (not depicted) storing the pretreatment liquid to the channel unit of the head 110a. The ink is supplied from a cartridge (not depicted) storing the ink to the channel unit of the head 110b.
The platens 150 are provided for the heads 110a and 110b respectively. Each platen 150 is a flat plate member. The platens 150 are respectively disposed below the heads 110a and 110b to face the jetting surfaces 110x of the heads 110a and 110b while being separated therefrom in a vertical direction. The surface of each platen 150 is a support surface 150x which supports the paper sheet P for which recording is performed by the heads 110a and 110b.
The feed mechanism 120 includes a feed tray 121 in which paper sheets P are accommodated and a feed roller 121r which is attached to the feed tray 121. The feed tray 121 is installable or detachable with respect to the casing 100a in a sub scanning direction. The controller 180 performs the control so that the drive of a feed motor (not depicted) rotates the feed roller 121r to teed an uppermost paper sheet P of the paper sheets P in the feed tray 121.
The conveyance mechanism 130 includes a guide 131, roller pairs 132 to 138, and rollers 139a to 139e. The guide 131 forms a conveyance route of the paper sheet P which extends from the feed mechanism 120, passes between the jetting surfaces 110x of two heads 110a, 110b and the support surfaces 150x, and reaches the detachable tray 1 on the receiving tray 100e and a conveyance route of the paper sheet P which extends from the manual feed tray 100d, passes between the jetting surfaces 110x of two heads 110a, 110b and the support surfaces 150x, and reaches the detachable tray 1 on the receiving tray 100e. The roller pairs 132 to 138 and the rollers 139a to 139e are disposed along the conveyance routes. The controller 180 performs the control so that the drive of a conveyance motor (not depicted) rotates the roller pairs 132 to 138 to apply conveyance force to the paper sheet P fed from the feed mechanism 120.
When the paper sheet P conveyed by the conveyance mechanism 130 passes between the jetting surfaces 110x of the heads 110a, 110b and the support surfaces 150x, the controller 180 controls the heads 110a and 110b to jet liquids from jetting ports. An image is formed on the paper sheet P by allowing the jetted liquids to land on the paper sheet P. The paper sheet P on which the image is formed (for which recording is performed) is discharged from the discharge port 100f in the first direction D1 and then is received by the detachable tray 1 on the receiving tray 100e. The first direction D1 intersects a common tangent of two rollers constituting the roller pair 138, and it is orthogonal to the main scanning direction (second direction) D2.

Each of the guide members 3 includes a tapered portion 3a which is tapered inward in the main scanning direction D2. The tapered portion 3a is formed such that its center part in a width direction orthogonal to the longitudinal direction D3 of the guide member 3 protrudes inward, resulting in a sharp front edge 3a1. The front edge 3a1 of the tapered portion 3a can come into point contact with the paper sheet P. The tapered portion 3a is continuously formed along the longitudinal direction D3 of the guide member 3.
The guide members 3 are disposed such that the front edges 3a1 of the tapered portions 3a face each other in the main scanning direction D2. The guide members 3 are disposed such that the front edges 3a1 of the tapered portions 3a make contact with both sides in the main scanning direction D2 of the paper sheet P which is discharged from the discharge port 100f to fall toward the receiving surface 2a, with the detachable tray 1 installed in the receiving tray 100e. The guide members 3 guide the paper sheet P on both sides in the main scanning direction D2.

The inclined surface 7, which constitutes a part of the inner side surface of the guide member 3, is positioned at a downstream end of the guide member 3 in the first direction D1. The inclined surface 7 is inclined inward in the main scanning direction D2 from the downstream end of the guide member 3 to the front edge 3a1 of the tapered portion 3a. The inclined surface 7 extends from the downstream end to the front edge 3a1 of the guide member 3.
The inclined surface 8, which constitutes a part of an upper surface of the guide member 3, is positioned at an upper end of the guide member 3. The inclined surface 8 is inclined upward from an inner end of the guide member 3 in the main scanning direction D2 to an outer end. The inclined surface 8 extends from the upstream end of the guide member 3 in the first direction D1 to the front edge 3a1.
The inclined surface 9, which constitutes apart of the upper surface of the guide member 3, is positioned at the upper end of the guide member 3. The inclined surface 9 is inclined upward from its upstream end in the first direction D1 to downstream end. The inclined surface 9 extends from the upstream end of the guide member 3 in the first direction D1 to the center of the guide member 3. The inclined surface 9 is disposed outside the inclined surface 8 in the main scanning direction D2.
A surface 10, which constitutes a part of the upper surface of the guide member 3, is positioned at the upper end of the guide member 3. The surface 10 is a substantially horizontal surface with the detachable tray 1 installed in the receiving tray 100e.

The center arm 141a is disposed in the center of the shaft 144 in the main scanning direction D2. The arms 142 and 143 are respectively disposed at a first end and a second end of the shaft 144x in the main scanning direction D2. One of the side arms 141b is disposed between the center arm 141a and the arm 142 in the main scanning direction D2, and the other of the side arms 141b is disposed between the center arm 141a and the arm 143 in the main scanning direction D2.
Of the arms 141a, 141b, 142, and 143, the arms 142 and 143 do not extend beyond the discharge port 100f and are disposed in the casing 100a. The arms 141a and 141b extend beyond the discharge port 100f.
The center arm 141a, which is positioned in the center of the discharge port 100f in the main scanning direction D2, makes contact with a center part of the paper sheet P in its width direction. The side arms 141b, which are positioned at a first end and a second end of the discharge port 100f in the main scanning direction D2, make contact with a first end and a second end of the paper sheet P in its width direction. The side arms 141b are equal in length, and the length of the side arms 141b is shorter than the length of the center arm 141a. A downstream end of the center arm 141a in the first direction D1 curves upward.
The back surfaces (surfaces facing the discharge port 100f) of the arms 141a and 141b are contact surfaces 141a1 and 141b1 (see
The pressing member 141 is in an initial position (a position depicted by the solid line in
The pressing member 141 swings by receiving the external force from the paper sheet P when the front end of the paper sheet P discharged from the discharge port 100f makes contact with the contact surfaces 141a1 and 141b1. Namely, the pressing member 141 in the first range SR1 swings to reach the second range SR2. Then, the pressing member 141 in the second range SR2 swings to reach the first range SR1. When the pressing member 141 reaches the initial position or the contact surfaces 141a1 and 141b1 make contact with the paper sheet P received by the receiving surface 2a, the pressing member 141 comes to rest. The paper sheet P goes to the stopper 5 after swinging the pressing member 141 from the first range SR1 to the second range SR2. The paper sheet P falls on the receiving surface 2a after its front end abuts against the stopper 5. The paper sheet P moves in a direction opposite to the first direction D1 while being supported by the receiving surface 2a, and the paper sheet P stops when its rear end abuts against the abutting surface 4a.
The pressing member 141 swings depending on the amount of the paper sheet(s) P received by the receiving surface 2a (see
Although
As described above, the pressing member 141 is configured to press the paper sheet P toward the receiving tray 100e by making the contact surfaces 141a1 and 141b1 contact with the paper sheet P discharged from the discharge port 100f. The pressing member 141, for example, prevents the paper sheet P from falling from the receiving tray 100e and prevents the paper sheet P from curling.
A full-load sensor 143S is installed to the arm 143. The full-load sensor 143S includes a light emitting part and a light receiving part disposed to face the light emitting part. The full-load sensor 143S outputs an on signal when the light receiving part receives the light emitted from the light emitting part, and the full-load sensor 143S outputs an off signal when the light receiving part receives no light. When the pressing member 141 is in the first range SR1, the light emitted from the light emitting part is blocked by the arm 143 and it is not received by the light receiving part. Thus, the full-load sensor 143S outputs the off signal. When the pressing member 141 is in the second range SR2, the light emitted from the light emitting part is received by the light receiving part without being blocked by the arm 143. Thus, the full-load sense 143S outputs the on signal. The controller 180 determines that a predetermined amount of paper sheets P is received by the receiving surface 2a when the controller 180 receives the on signal from the full-load sensor 143S for a predetermined time or longer. Note that the full-load sensor 143S outputs the on signal when the paper sheet P discharged from the discharge port 100f makes the pressing member 141 passes the intermediate position. In this case, however, the time during which the full-load sensor 143S outputs the on signal is shorter than the predetermined time. Thus, the controller 180 does not determine that the maximum amount of paper sheets P is loaded on the detachable tray 1.
The controller 180 includes a Central Processing Unit (CPU) which is an arithmetic processing unit, a Read Only Memory (ROM), a Random Access Memory (RAM), an Application Specific Integrated Circuit (ASIC), an Interface (I/F), and an Input/Output port (I/O). The ROM stores fixed data, such as programs to be executed by the CPU. The RAM temporarily stores data required for the CPU to execute each of the programs. The ASIC performs, for example, rewriting and sorting of image data (e.g., signal processing and image processing). The I/F performs data transmission and data reception with an external device, such as a personal computer connected to the printer 1. The I/O performs signal transmission and signal reception with various sensors. The CPU, which is electrically connected to respective parts of the controller 180 except for the CPU, performs control based on the data transmitted from the respective parts.
An explanation will be made about the behavior of the paper sheet P discharged from the discharge port 100f with reference to
Although the downstream end of the paper sheet P in the first direction D1 typically passes above the guide members 3 as described above, the paper sheet P may make contact with the conveyance route depending on the obliquely passing state of the paper sheet P conveyed by the conveyance mechanism 130. This may reduce the conveyance force of the paper sheet P. For example, when the downstream end of the paper sheet P makes contact with the upper ends of the front edges 3a1 of the guide members 3, the paper sheet P is more likely to bend between the front edges 3a1 of the tapered portions 3a and the discharge port 100f this is because the upper parts of the front edges 3a1 of the guide members 3 are further away from the discharge port 100f in the first direction D1 than the lower parts thereof. Helping the paper sheet P bend makes the downstream end of the paper sheet P in the first direction D1 pass the front edges 3a1 of the tapered portions 3a easily, thereby preventing the paper sheet P from getting jammed between the front edges 3a1 of the tapered portions 3a and the discharge port 100f. Further, since the guide members 3 include the inclined surfaces 6 respectively, the paper sheet P discharged from the discharge port 100f is further prevented from getting jammed between the front edges 3a1 of the tapered portions 3a of the guide members 3 and the discharge port 100f as compared with a case using guide members without the inclined surfaces 6.
The paper sheet P may be discharged from the discharge port 100f with skew. In this case, the paper sheet P abutting against the stopper 5 may fall toward the receiving surface 2a so that the right end of the paper sheet P at the upstream side in the first direction D1 overlaps with the guide member 3 in the vertical direction, as depicted in
The paper sheet P falling on receiving surface 2a slides downward along the slope of the receiving surface 2a. As depicted in
The left end of the paper sheet P at the upstream side in the first direction D1 may abut against the abutting surface 4a in a state that the obliquely passing state of the paper sheet P is not corrected perfectly, as depicted by the alternate long and two short dashes line in
Since the guide members 3 include the tapered portions 3a respectively, the distance between the guide members 3 in the main scanning direction D2 is shorter than the distance between conventional plate-shaped guide members G which are depicted by the alternate long and two short dashes line in
Since the guide members 3 are configured to be movable in the main scanning direction D2, a user may erroneously dispose the guide members 3 at positions depicted by the alternate long and two short dashes lines in
Subsequently, an explanation will be made about the control to be executed by the controller 180 with reference to
First, the controller 180 determines whether it receives a recording command transmitted from an external device (F1). When the controller 180 does not receive the recording command (F1: NO), the controller 180 re-executes the processing F1. When the controller 180 receives the recording command (F1: YES), the controller 180 executes recording operation (F2).
In F2, the controller 180 controls the conveyance operation of the paper sheet P by use of the conveyance mechanism 130 and the liquid jetting operation by use of the heads 110a, 110b which are synchronized with the conveyance of the paper sheet P to record an image on the paper sheet P based on the recording command received in F1. The paper sheet P having the image recorded thereon is discharged from the discharge port 100f on the detachable tray 1.
Next, the controller 180 determines whether the recording for a predetermined number of paper sheets on the basis of the recording command is completed (F3). When the recording for the predetermined number of paper sheets is completed (F3: YES), the recording operation ends and this routine ends.
When the recording for the predetermined number of paper sheets is not completed (F3: NO), the controller 180 determines whether a maximum amount of paper sheets P is loaded on the detachable tray 1 based on the signal from the full-load sensor 143S (F4). When the maximum amount of paper sheets P is not loaded on the detachable tray 1 (F4: NO), the controller 180 continues the recording operation for the paper sheet P. When the maximum amount of paper sheets P is loaded on the detachable tray 1 (F4: YES), the controller 180 stops the recording operation (F5). This prevents the paper sheet P from being discharged from the discharge port 100f beyond an acceptable amount which can be accepted by the detachable tray 1. Any output means (not depicted), such as a speaker, may inform the user of the fact that the maximum amount of paper sheets P is loaded on the detachable tray 1. Then, this routine ends.
The user may erroneously dispose the guide members 3 such that the distance between the guide members 3 in the main scanning direction D2 is shorter than the width of the paper sheet P. In this case, the paper sheet P discharged from the discharge port 100f to the detachable tray 1 is disposed on the guide members 3. This makes the full-load sensor 143s output the on signal for the predetermined time or longer. Thus, in the processing F4, the controller 180 determines not only whether the maximum amount of paper sheets P is loaded on the detachable tray 1 but also whether the paper sheet P is disposed on or above the guide members 3. When the paper sheet P is disposed on the guide members 3, the controller 180 stops the recording operation similarly to the above case based on the signal from the full-load sensor 143S (F5). This prevents the paper sheet P from being discharged from the discharge port 100f in the state that the paper sheet P is disposed on the guide members 3. Then, this routine ends.
In the detachable tray 1 of the printer 100 of this embodiment, the guide members 3 include the tapered portions 3a respectively. Thus, the detachable tray 1 of this embodiment improves the aligning property of the paper sheet P while preventing the paper sheet P discharged from the discharge port 100f with skew from getting jammed between the guide members 3, without making the distance between the front edges 3a1 of the guide members 3 significantly longer than the width of the paper sheet P.
The guide members 3 are supported by the receiving member 2 to be movable in the main scanning direction D2. Thus, the distance between the guide members 3 in the main scanning direction D2 is adjusted depending on the size of the paper sheet P.
The stopper 5 is supported by the receiving member 2 to be movable in the first direction D1. Thus, the position of the stopper 5 is adjusted depending on the size of the paper sheet P.
The guide members 3 are disposed such that the front edges 3a1 of the tapered portions 3a face each other in the main scanning direction D2. This allows the distance between the guide members 3 in the main scanning direction D2 to be shorter than the case in which the distance between the guide members 3 in the main scanning direction D2 is longer than the width of the paper sheet P, but the front edges 3a1 of the tapered portions 3a are displaced from each other in a direction parallel to the receiving surface 2a and orthogonal to the main scanning direction D2. Thus, the aligning property of the paper sheet P on the receiving surface 2a can be improved. The guide members 3 of which front edges 3a1 are displaced from each other need to increase a distance between the guide members 3 according to its displacement amount, like the guide members G. Otherwise, the paper sheet P may get jammed between the guide members 3.
The front edges 3a1 of the tapered portions 3a are formed to come into point contact with the paper sheet P. This allows the distance between the guide members 3 in the main scanning direction D2 to be shorter than the case in which parts making contact with the paper sheet P have a shape parallel to the receiving surface 2a and long in the direction orthogonal to the main scanning direction D2. The aligning property of the paper sheet P is improved, accordingly.
The detachable tray 1 includes the abutting member 4 having the flat abutting surface 4a. This makes it possible to correct the obliquely passing state of the paper sheet P, even when the surface of the side wall 100s1 of the receiving tray 100e which faces the abutting member 4 has, for example, a concavo-convex shape.
The receiving member 2 of the above embodiment includes the receiving surface 2a which is inclined such that its downstream end is positioned above its upstream end in the first direction D1. The receiving member 2, however, may be horizontal. In a first modified example, a receiving member 202, which is constructed of a flat-plate member as depicted in
In the first modified example also, the paper sheet P discharged from the discharge port 100f abuts against the stopper 5 after its downstream end in the first direction D1 passes through above the guide members 3. The alternate long and two short dashes line of

In the above description, the preferred embodiment of the present teaching is explained. The present teaching, however, is not limited thereto, and may have various modifications without departing from the gist and scope of the patent claims below. For example, although the discharge apparatus 101 is configured by installing the detachable tray 1 on the receiving tray 100e in the above embodiment, the discharge apparatus may be configured by incorporating a component or structure equivalent to the detachable tray 1 into the receiving tray 100e. Namely, the receiving member 2 may be constructed of the upper wall 100t, the guide members 3 and the stopper 5 may be provided in the upper wall 100t, and the abutting member 4 may be constructed of the side wall 100s1. The discharge apparatus with such a configuration can obtain the same effects as the above embodiment.
The position, in the printer, to which the detachable tray 1 is installed (i.e., the position of the receiving tray) is not limited to the upper part of the casing, and it may be, for example, a side part of the casing. Each guide member (a protruding portion of the present teaching) may extend in the vertical direction, or may be inclined toward the discharge port 100f from its lower side to its upper side.
In the above embodiment, the stopper 5 may not be provided; each of the guide members 3 may not have the inclined surfaces 6 to 9; each of the guide members 3 may be fixed to the receiving member 2 so as not to be movable; the stopper 5 may be fixed to the receiving member 2 so as not to be movable; the sensor 143S detecting whether the paper sheet P is positioned on or above the guide members 3 may not be provided; and the guide members 3 may be disposed such that the front edges 3a1 are slightly displaced from each other in the direction parallel to the receiving surface 2a and orthogonal to the main scanning direction D2.
Although the abutting member 4 is constructed of the flat plate in the above embodiment, it may be constructed of bar-like members disposed between the center and both ends in the main scanning direction D2 of the paper sheet P received by the receiving surface 2a. The bar-like members may be disposed on the inside, in the main scanning direction D2, of an upstream corner of the paper sheet P in the first direction D1. In that case, if the paper sheet P slides on the receiving surface 2a obliquely toward the bar-like members, the obliquely passing state of the paper sheet P can be corrected by making the paper sheet P abut against the bar-like members.
In the above description, the examples in which the present teaching is applied to the printer which jets the ink from nozzles to perform recording are explained. The present teaching, however, is not limited thereto. The discharge apparatus may be any apparatus discharging a recording medium. The recording medium is not limited to the paper sheet, and it may be, for example, cloth. The present teaching is applicable to any other liquid jetting apparatus than the printer which jets any other liquid than the ink from jetting ports. The present teaching is applicable to both of a line-type apparatus and a serial-type apparatus. The recording unit is not limited to the ink-jet system, and it may be a laser system, a thermal system, or the like.
