Description

  The present invention relates to a recording apparatus such as a printer, and more particularly to a paper feed tray unit for loading recording media provided in a paper feeding unit of the recording apparatus.

  2. Description of the Related Art Conventionally, in a recording apparatus such as a printer, a copying machine, or a facsimile, a feeding apparatus that automatically and continuously feeds a sheet material that is a recording medium has been used. In that case, particularly in a small-sized recording apparatus, a sufficient area cannot be secured in the recording apparatus main body for stacking and holding a plurality of sheet materials to be fed, so a plurality of sheet materials are stacked. A paper feed tray needs to be prepared separately and attached to the recording apparatus main body.

  In recent years, as such a paper feed tray, not only a detachable paper feed tray but also a paper feed tray that can be stored as if it is integrated with an exterior portion of a recording apparatus main body has been widely used. In other words, this sheet feeding tray takes a set position where sheets can be stacked and held so that they can be supplied when in use (recording operation), and is fed when not in use (when no recording operation is performed). In this configuration, it is possible to take a standby position that is stored so as to cover the unit (paper feeding device) so that foreign matter such as dust and dust does not enter.

Further, in the conventional example of such a paper feed tray, a paper feed cover that is attached to the exterior of the recording apparatus main body so as to be swingable and openable, and is slidably attached to the paper feed cover. There is also a configuration in which the auxiliary tray is slid and stored in the paper feed cover when not in use, and the paper feed cover can be closed (see, for example, Patent Document 2).
Japanese Patent Laid-Open No. 06-286268 (page 3, FIG. 4) JP 2001-163454 A (2nd page, FIG. 7)

  However, in the configuration in which the auxiliary tray is slidable with respect to the paper feed cover as in the above-described conventional example, in order to stabilize the posture in a state where the auxiliary tray is extended during use, the auxiliary tray is placed between the paper feed cover and the auxiliary tray. In addition, a support portion having a certain size is required, and a portion where the paper feed cover and the auxiliary tray overlap must be large to some extent. Therefore, the sheet stacking surface becomes narrower than the total length of the sheet feed cover and the auxiliary tray.

  Therefore, it is necessary to make the paper feed cover and the auxiliary tray itself larger or to increase the number of auxiliary trays to be used. Increasing the size of the paper feed cover and auxiliary tray requires a large space for storing the paper feed cover and auxiliary tray in the exterior of the recording device, and the space required for the storage operation also increases. The arrangement and configuration of other members of the recording apparatus may be affected.

  When the number of auxiliary trays is increased, for example, as shown in FIG. 11, a first auxiliary tray 126B that can slide with respect to the paper feed cover 126A and a first auxiliary tray 126B that can slide with respect to the first auxiliary tray 126B. Two auxiliary trays 126C are provided, and the pressure plate 21, the paper feed cover 126A, the first auxiliary tray 126B, and the second auxiliary tray 126C constitute a sheet material stacking surface. The sheet material stacked on the sheet material stacking surface is conveyed and recorded inside the exterior portion including the upper case 98, the lower case 99, the access cover 97, the connector cover 96, and the like while being guided by the movable side guide 23. The paper is discharged to the paper discharge tray 46. Such a configuration leads to an increase in the number of parts, a complicated configuration, and a corresponding increase in cost.

  Furthermore, when the paper feed cover and auxiliary tray are enlarged, the weight increases, so a larger support portion is required. When the number of auxiliary trays is increased, it is necessary to provide a support portion between the paper feed cover and each auxiliary tray. Since the number of support portions increases, in each case, the total area of the support portions where the members overlap is larger, and the sheet stacking surface is narrower than the total length of the paper feed cover and the auxiliary tray. It cannot be solved efficiently.

  Accordingly, an object of the present invention is to provide a recording apparatus that can secure a sufficient sheet material stacking surface without enlarging or increasing the number of paper trays for stacking sheet materials and that can easily store the paper trays. It is to provide.

  The present invention relates to a recording apparatus having a conveying means for conveying a recording medium and a recording means for recording on the recording medium, a first paper tray that is swingably attached to the recording apparatus main body, A second paper tray that is swingably attached to the paper tray, and the first paper tray of the second paper tray with the second paper tray stored inside the first paper tray. And a restricting member for restricting relative swinging to the head.

  Note that when the first paper tray is open with respect to the recording apparatus main body and the second paper tray is open with respect to the first paper tray, the first paper tray and the first paper tray The two paper trays continuously form a stacking surface for recording media.

  When the second paper tray is closed with respect to the first paper tray and stored inside the first paper tray, when the first paper tray is swung in the closing direction with respect to the recording apparatus main body, the regulating member is The second paper tray is restricted from swinging in the direction away from the first paper tray.

  The restricting member may be formed integrally with the exterior portion of the recording apparatus main body.

  The recording medium may have a movable guide that regulates the stacking position and the conveyance direction, and the regulating member may be a part of the movable guide.

  The first paper tray is a paper feed cover incorporated in the exterior of the recording apparatus main body when closed.

  According to the present invention, the second paper tray is opened and closed by swinging rather than sliding relative to the first paper tray that is swingably attached to the recording apparatus main body. Therefore, it is not necessary to form a large support portion overlapping with the conventional one. Therefore, since it is not necessary to increase the size of each paper tray or increase the number of sheets, the entire apparatus can be reduced in size, and the degree of freedom of the configuration and arrangement of other members is not hindered.

  A continuous recording medium stacking surface is configured with both paper trays open, thereby ensuring a sufficient recording medium stacking area.

  Further, when the first paper tray is closed with the second paper tray stored inside the first paper tray, the second paper tray is separated from the first paper tray by the restriction member. If the configuration is such that the swinging is restricted, both the paper trays can be handled almost integrally, and the storing operation can be easily performed. As a result, even if both the paper trays are swingable, it is possible to obtain good operability by providing a simple restricting member without providing a fixing means or a lock mechanism.

  If the restricting member is formed integrally with the exterior portion of the recording apparatus main body, it is possible to save space, simplify the configuration, and reduce the cost. Further, when the restricting member is formed as a part of the movable guide for guiding the recording medium, in addition to the effects described above, the degree of freedom of the configuration and arrangement of the other members can be increased.

  Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are perspective views of a recording apparatus according to a first embodiment of the present invention, FIGS. 3 and 4 are perspective views showing an internal mechanism of the recording apparatus, FIG. 5 is a sectional view thereof, and FIGS. FIG. 4 is an enlarged view for explaining a paper feed tray portion of the recording apparatus. The recording apparatus 1 according to the present embodiment roughly includes a paper feeding tray unit 10, a paper feeding unit (paper feeding device) 2, a paper feeding unit 3, a paper discharging unit 4, a carriage unit 5, a cleaning unit 6, a recording head, and the like. It consists of an electric board part. Therefore, these are divided into items and the schematic configuration is described sequentially.

(A) Paper Feed Tray Unit The paper feed tray unit 10 which is a main feature of the present invention is a paper feed cover (first paper tray) 26A for stacking and holding sheet materials as recording media (not shown). And a paper feed tray (second paper tray) 26B. The paper feed cover 26A is swingably attached to the upper case 98 of the recording apparatus main body, and the paper feed tray 26B is swingably attached to the paper feed cover 26A. The paper feed cover 26A and the paper feed tray 26B are both plate-like members, and can be closed so as to cover the paper feed unit 2 as shown in FIG. 1 when not in use, and as shown in FIG. In addition, the sheet feeding cover 26A and the sheet feeding tray 26B can be opened to be in a continuous state to form a sheet material stacking surface.

(B) Paper Feed Unit The paper feed unit 2 shown in FIGS. 3 to 5 feeds the pressure plate 21 on which the sheet material can be stacked and the sheet material continuously with the paper feed cover 26A and the paper feed tray 26B. The base 20 includes a sheet feeding roller 28, a separation roller 241 for separating the sheet material one by one, a return lever 22 for returning the sheet material to the stacking position, and the like.

  The paper feed roller 28 has a cylindrical shape, and one separation roller rubber is provided on the reference side in the width direction of the sheet material. When the paper feed roller 28 rotates, the sheet material is fed by the frictional force of the separation roller rubber. The paper feed roller 28 is rotationally driven via a gear from a paper feed motor 273 (see FIG. 3) provided in the paper feed unit 2.

  A movable side guide (movable guide) 23 that is movable in the left-right direction is attached to the pressure plate 21, and the movable side guide 23 regulates the stacking position and conveying direction of the sheet material in the width direction. That is, the sheet material is stacked in a range sandwiched between the reference position in the width direction and the movable side guide 23 moved to an appropriate position. The pressure plate 21 is rotatably attached to the base 20 and is biased toward the paper feed roller 28 by a pressure plate spring 212 as shown in FIG. A separation sheet made of a material such as artificial leather having a large coefficient of friction is provided at a position of the pressure plate 21 facing the paper feed roller 28 to prevent the sheet material P from being double-fed. The pressure plate 21 is configured to abut against or separate from the paper feed roller 28.

  A separation roller holder 24 is rotatably attached to the base 20, and a separation roller 241 for separating the sheet material one by one is attached to the separation roller holder 24. It is energized towards.

  Next, an operation for feeding paper by the paper feed unit 2 having the above-described configuration will be described.

  In the normal standby state, the pressure plate 21 and the separation roller 241 are separated from the paper feed roller 28. The return lever 22 is in a position to return the sheet material to the stacking position and close the stacking port so that the stacked sheet material does not enter the back.

  When the paper feeding operation starts from this standby state, first, the separation roller 241 contacts the paper feeding roller 28 by driving the motor. Then, the return lever 22 is released, and the pressure plate 21 comes into contact with the paper feed roller 28. In this state, sheet feeding starts. Since the width of the sheet material path in the sheet thickness direction is limited by the preceding separation unit provided in the base 20, only a predetermined number of sheet materials or less are nipped by the sheet feeding roller 28 and the separation roller 241. Sent to the department. The fed sheet material is separated one by one at the nip portion, and only the uppermost sheet material is conveyed.

  When the sheet material reaches the positions of a conveyance roller 36 and a pinch roller 37 described later, the pressure plate 21 and the separation roller 241 are separated from the paper feed roller 28, and the return lever 22 returns to the sheet material stacking position. At this time, the sheet material remaining in the nip portion constituted by the paper feed roller 28 and the separation roller 241 is returned to the stacking position.

(C) Paper feeding part The paper feeding part 3 is provided in the chassis 11 made of a bent metal sheet.

  As shown in FIGS. 3 and 4, a plurality of pinch rollers 37 that follow the conveyance roller 36 are provided so as to contact the conveyance roller 36. The pinch roller 37 is held by the pinch roller holder 30 and is urged by a pinch roller spring, so that the pinch roller 37 is in pressure contact with the conveying roller 36 and generates a conveying force for the sheet material. A rotation shaft of the pinch roller holder 30 is attached to a bearing of the chassis 11, and the pinch roller holder 30 rotates around the rotation shaft. Further, as shown in FIG. 5, a paper guide flapper 33 and a platen 34 for guiding the sheet material are disposed at the entrance of the paper feeding unit 3 to which the sheet material is conveyed. Further, the pinch roller holder 30 is provided with a PE sensor and a PE sensor lever 321 for detecting the leading edge and the trailing edge of the sheet material. The platen 34 is attached to the chassis 11 and positioned. The paper guide flapper 33 is rotatably fitted with the transport roller 36 and positioned in contact with the chassis 11.

  A recording head for forming an image based on image information is provided on the downstream side of the conveyance roller 36 in the sheet material conveyance direction.

  In the above-described configuration, the sheet material sent to the paper feeding unit 3 is guided by the pinch roller holder 30 (see FIGS. 3 and 4) and the paper guide flapper 33 (see FIG. 5), and the conveying roller 36 and the pinch roller 37 are guided. And sent to the nip. At this time, the PE sensor lever 321 and the PE sensor detect the leading edge of the conveyed sheet material and determine the print position of the sheet material based on the detected edge. Further, the sheet material is transported on the platen 34 by being driven by the transport motor 35 and rotating the transport roller 36 and the pinch roller 37. On the platen 34, a rib serving as a conveyance reference surface is formed. The rib manages a gap with the recording head, and controls the waving of the sheet material together with the paper discharge unit 4 described later. This configuration prevents the hitting from becoming large.

  As shown in FIG. 4, the rotation force of the conveyance motor 35 that is a direct current (DC) motor is transmitted to the pulley 361 provided on the rotation shaft of the conveyance roller 36 via the timing belt.

The carriage 50 is supported by a guide shaft 52 and a guide rail 111 that holds the rear end of the carriage 50 and maintains a gap between the recording head and the sheet material, and reciprocates in the direction perpendicular to the sheet material conveyance direction. Is possible. The guide shaft 52 is attached to the chassis 11. The guide rail 111 is formed integrally with the chassis 11. A sliding sheet 53 made of a thin plate of stainless steel or the like is attached to a portion of the guide rail 111 where the carriage 50 slides to reduce sliding noise.

  In order to fix the recording head to the carriage 50, the carriage 50 is provided with a head set lever 51. When the user operates the headset lever 51, the recording head is configured to press against the abutting portion in the carriage 50.

  As shown in FIG. 3, eccentric cams 521 are provided at both ends of the guide shaft 52, and a driving force is transmitted from the carriage lifting / lowering motor 58 to the eccentric cam 521 through the driving gear train 581, thereby causing the guide shaft to move. 52 can be moved up and down. In this way, the guide shaft 52 and the carriage 50 can be moved up and down to form an optimum gap even for sheet materials having different thicknesses.

  When an image is formed on a sheet material in the above-described configuration, the conveyance roller 36 and the pinch roller 37 convey the sheet material to a predetermined row position (predetermined position in the sheet material conveyance direction), and the carriage 50 is moved to a predetermined row position (sheet By moving the recording head to a predetermined position in a direction perpendicular to the material conveyance direction, the recording head is made to face the position on the sheet material where the image is to be formed. Thereafter, an image is formed by the recording head ejecting ink toward the sheet material by a signal from the electric substrate. The recording head is an ink jet recording head in which the ink tanks 71 of the respective colors are mounted so as to be individually replaceable. In this recording head, heat can be applied to the ink by a heater or the like, and the ink boils the film by this heat, and the ink changes from the nozzle of the recording head due to the pressure change caused by the growth or contraction of bubbles due to the film boiling. An image is formed on the sheet material by discharging.

(E) Paper Discharge Unit The paper discharge unit 4 includes two paper discharge rollers 40 and 41, a spur 42 configured to contact the paper discharge rollers 40 and 41 with a predetermined pressure and be driven to rotate, and a conveyance roller 36. It is composed of a gear train for transmitting the drive to the paper discharge rollers 40 and 41.

  The paper discharge rollers 40 and 41 are attached to the platen 34. The upstream discharge roller 40 has a configuration in which a plurality of rubber portions are provided on a metal shaft. The paper discharge roller 40 is driven by a driving force transmitted from the transport roller 36 via an idler gear. The downstream discharge roller 41 has a configuration in which a plurality of elastomers (elastic body portions) are provided on a synthetic resin shaft. The paper discharge roller 41 is driven by a driving force transmitted from the paper discharge roller 40 via an idler gear.

  The spur 42 is configured by integrally forming a stainless steel thin plate having a plurality of convex shapes on the outer peripheral portion thereof with a synthetic resin, and is attached to a spur holder 43. The spur 42 is attached to the spur holder 43 and pressed toward the paper discharge rollers 40 and 41 by a spur spring which is an elongated rod-shaped coil spring. The plurality of spurs are provided at positions opposed to the rubber portions and the elastic body portions of the paper discharge rollers 40 and 41 to mainly generate a sheet material conveying force, and the rubber portions of the paper discharge rollers 40 and 41 and It is provided so as to face the position where there is no elastic body part, and mainly serves to suppress lifting when the sheet material is printed.

  With the above-described configuration, the sheet material on which the image is formed by the carriage unit 5 is conveyed while being sandwiched between the nip portions of the discharge rollers 40 and 41 and the spurs 42 and is discharged onto the discharge tray 46 shown in FIGS. Discharged. The paper discharge tray 46 is divided into a plurality of parts and can be stored under a lower case 99 described later. The paper discharge tray 46 is pulled out during use. The paper discharge tray 46 is configured to be higher toward the front end and higher at both ends thereof, so that the stackability of the discharged sheet material is good and the printing surface can be prevented from rubbing. .

Further, a one-way clutch is provided so that the pump 60 is operated by rotation of the cleaning motor 69 in one direction, and the blade 62 and the cap 61 are moved up and down by rotation in the opposite direction.

(G) Exterior Unit Each of the above-described units, that is, the paper feed tray unit 10, the paper feed unit 2, the paper feed unit 3, the paper discharge unit 4, the carriage unit 5, and the cleaning unit 6 is incorporated in the chassis 11 and the printer mechanism. Forming part. The exterior part is attached so that the surroundings of the mechanism part may be covered. As shown in FIGS. 1 and 2, the exterior part mainly includes a lower case 99, an upper case 98, an access cover 97, a connector cover 96, and a front cover 95.

  A rail is provided at the lower part of the lower case 99, and the divided paper discharge tray 46 (see FIGS. 2 and 6) is configured to be housed along this rail. Further, the front cover 95 is configured to be able to close the paper discharge port when not in use.

  An access cover 97 is swingably attached to the upper case 98. A part of the upper surface of the upper case 98 has an opening, and the ink tank 71 and the recording head can be exchanged from this opening. Further, as described above, the paper feed cover 26A is swingably attached to the upper case 98. The upper case 98 and the lower case 99 are joined to each other by elastic engaging claws, and the connector cover 96 covers the portion where the connector portion between the cases 98 and 99 is provided.

  Next, the configuration of the paper feed tray unit 10 which is the main characteristic part of the present invention will be described in detail with reference to FIGS. 6 to 10 show a state in which only the paper feed tray 26B is closed, FIG. 6 is a perspective view of the entire recording apparatus, and FIG. 7 is a sectional view showing the paper feed cover 26A, the paper feed tray 26B, and the upper case 98.

  In FIG. 6, the paper feed cover 26A is attached to the upper case 98 so as to be swingable around the hinge H1, and the paper feed tray 26B is attached to the paper feed cover 26A so as to be swingable around the hinge H2. ing. 7 to 9, a regulating member 98A is integrally formed with the upper case 98, and the regulating member 98A regulates the swing of the paper feed tray 26B. Specifically, the paper feed cover 26A is opened as shown in FIGS. 6 and 7, and is further increased by the structural restriction of the hinge H1 or by a stopper provided on the upper case 98 or other member. It is regulated so as not to open. Further, the paper feed cover 26A is held in a state in which the entrance to the paper feed unit 2 of the upper case 98 is closed in the closed state. Therefore, the paper feed cover 26A can swing around the hinge H1 between the open state shown in FIGS.

  On the other hand, the paper feed tray 26B is swingable relative to the paper feed cover 26A about the hinge H2, and is in a state (set position) that is substantially in a straight line with the paper feed cover 26A (set position). Similarly to 26A, the hinge H2 is regulated and held so as not to open any more by regulation of the hinge H2 or by a stopper provided on the paper feed cover 26A or another member. Further, in the state of being stored inside the paper feed cover 26 </ b> A, relative swinging with respect to the paper feed cover 23 </ b> A is restricted by the restriction member 98 </ b> A provided in the upper case 98. This point will be described in detail below.

  In the state shown in FIGS. 6 and 7, the paper feed cover 26A is opened and the paper feed tray 26B is closed. At this time, due to the positional relationship between the hinge H2 and the center of gravity of the paper feed tray 26B, the paper feed tray 26B is leaning against the paper feed cover 26A. This state is maintained until the paper feed cover 26A starts swinging in the closing direction and approaches a state in which the paper feed cover 26A is aligned in a straight line in the vertical direction of the center of gravity of the hinge H2 and the paper feed tray 26B as shown in FIG. The paper cover 26A and the paper feed tray 26B swing almost integrally. If the paper feed cover 26A further swings in the closing direction from the state of FIG. 8, the paper feed tray 26B swings in a direction away from the paper feed cover 26A. At this time, as shown in FIG. 9, when the rocking of the paper feed tray 26B reaches a certain amount of rocking, the regulating member 98A contacts the paper feed tray 26B to regulate the rocking, and the paper feed tray 26B is more than that. This prevents the paper feed cover 26A from being separated. In this way, when the paper feed tray 23B is closed with respect to the paper feed cover 26A and stored inside the paper feed cover 26A, when the paper feed cover 26A is swung in the closing direction with respect to the recording apparatus main body, the regulating member 98A restricts the paper feed tray 26B from swinging away from the paper feed cover 26A. The restricting member 98A guides the paper feed tray 26B so as to operate integrally with the paper feed cover 26A.

  As described above, in the conventional configuration in which the paper feed tray is slid with respect to the paper feed cover, the support portion where the paper feed cover and the paper feed tray overlap must have a relatively large area. However, in the configuration of the present embodiment, since the paper feed tray 28B is rocked with respect to the paper feed cover 28A, it is firmly supported by the hinge H2, and the paper feed cover 28A and the paper feed tray 28B overlap. The part is not so necessary. Accordingly, it is not necessary to increase the size of the paper feed cover 28A and the paper feed tray 28B, and it is not necessary to increase the number of paper feed trays.

  In the present embodiment, two swingable trays, that is, the paper feed cover 26A and the paper feed tray 26B are used. When these are stored, the paper is fed by the action of the regulating member 98A. The tray 26B does not swing independently with respect to the paper feed cover 26A, and can be closed substantially integrally.

  If the paper feed cover 26A and the paper feed tray 26B swing relative to each other when the paper feed cover 26A and the paper feed tray 26B are closed and stored, the paper feed cover 26A that the user grips and closes. Therefore, there is a possibility that the sheet feeding tray 26 will be separated from the sheet, making it difficult to perform the storing operation. However, in this embodiment, since the paper feed cover 26A and the paper feed tray 26B can be operated in a substantially integrated state when closed and stored, the operability is greatly improved. Moreover, as shown in FIG. 6, when the paper feed cover A is opened, the paper feed tray 26B can be opened without coming into contact with the regulating member 98A. When in the open use state (set position), it can be easily operated without any obstacles. In the present embodiment, the regulating member 98A is integrally formed with the upper case 98 that is an exterior part. That is, the shape of the upper case 98 can be devised to restrict the swing of the paper feed tray 26B, so that the mechanism as described above can be configured in a small size and at low cost.

[Other Embodiments]
In the first embodiment described above, the restricting member 98A is integrally formed with the upper case 98. However, the restricting member 98A is disposed in the upper case because the movement of the movable side guide 23 in the width direction may be hindered. In some cases, it may be difficult to provide it in 98. In such a case, as shown in FIG. 10, a regulating member 23A is formed integrally with the movable side guide 23, that is, a part of the movable side guide 23 is used as a regulating member 23A to guide the paper feed tray 26B. You may make it the structure to carry out. Also in this case, the same effect as the first embodiment described above can be obtained, and the degree of freedom of the shape and arrangement of the regulating member can be increased.
