DETAILED DESCRIPTION OF THE INVENTION

[0008] The following describes in detail exemplary embodiments of the present invention with reference to the drawings. However, the dimensions, materials, shapes, and relative positions of the components described in the embodiments may be changed as appropriate depending on the configuration of the device to which the invention is applied and various conditions. In other words, the scope of the present invention is not limited to the following embodiments.

[0009] 1 to 7 are explanatory diagrams of a first embodiment of the present invention. The printing apparatus (recording apparatus) of this embodiment is an example of application as an inkjet printing apparatus equipped with a sheet supplying device for supplying sheets as printing media, a printing unit (recording unit) for printing images on the sheets, and a paper discharge unit for discharging the sheets to the front of the printing apparatus.

[0010] 1(a) and 1(b) are schematic diagrams of a printing apparatus 100 during front sheet ejection, which can accommodate two roll sheets (recording media) wound into a roll. Two sheet feeders 200 (feeders) are installed vertically. The upper one is called the upper feeder, and the lower one is called the lower feeder. Images are printed on sheets 1 selectively fed from the two roll sheets. Once printed, the sheets 1 are ejected from a front ejection guide 110 (ejection port) located at the front of the printing apparatus. Using various switches on the operation panel 2, the user can specify the size of the sheets 1, switch between online and offline modes, and input various commands to the printing apparatus 100. FIG. 1(c) is a schematic cross-sectional view (cross-section AA in FIG. 1(b)) of the main components of the printing apparatus 100 during front sheet ejection. Two sheet feeders 200, each corresponding to one roll R, are installed vertically. The sheet 1 drawn from the roll R by the supply device 200 is transported by a sheet transport unit (transport mechanism) 300 along a sheet transport path to a printing unit 400 where an image can be printed. Upper and lower roll covers 201 are arranged on the front of the supply device 200 so as to be rotatable relative to the printing device 100. The upper roll cover 201 is referred to as the upper cover member, and the lower roll cover 201 is referred to as the lower cover member. When the roll cover 201 is closed, it serves as the exterior surface. The roll R is loaded into the supply device 200 after the roll cover 201 is opened. The printing unit 400 prints an image on the sheet 1 by ejecting ink from an inkjet print head 18. The print head 18 ejects ink from ejection orifices using ejection energy generating elements such as electrothermal conversion elements (heaters) and piezoelectric elements. The print head 18 is not limited to an inkjet type, and the printing type of the printing unit 400 is not limited either, and may be, for example, a serial scan type or a full line type. In the case of the serial scan type, an image is printed by conveying the sheet 1 and scanning the print head 18 in a direction intersecting the conveying direction of the sheet 1.In the case of the full-line method, an elongated print head 18 extending in a direction intersecting the conveying direction of the sheet 1 is used, and an image is printed on the sheet 1 while the sheet 1 is continuously conveyed.

[0011] The sheet 1 guided to the printing unit 400 is transported in the transport direction F1 by the transport roller pair 14. A cutter 21 and a front discharge guide unit 110 are arranged in this order downstream of the print head 18 in the transport direction F1, and the sheet 1 passes over the top of the front discharge guide unit 110 and is discharged to the front of the printing device, and after printing is completed, the cut sheet is discharged by its own weight and stored in a front discharge storage unit 29 that can be pulled out from the bottom of the printer and is located below in the direction of gravity.

[0012] Next, the front discharge paper storage section 29 will be described in detail using Figure 2. Figure 2(a) is a diagram showing the printing device 100 in the state shown in Figure 1(b) with a portion thereof not shown. The front discharge paper storage section 29 is made up of a first holding member 130 that supports one end of a sheet-like receiving member (basket cloth) 120 made of flexible polyester, and a second holding member 140 that supports the other end of the holding member on the side closer to the printing device 100. The sheet cloth 120 has a receiving surface for receiving the discharged sheet 1 (recording medium). In addition, side rods 131 connected to both ends of this first holding member 130 are pivotally supported by supports that are integrally provided with the drawer section 150 (storage section). This provides a support mechanism that is configured to be rotatable about a rotation center 251 in the direction of arrow B from the state shown in FIG. 2(a). Furthermore, the drawer section 150 is configured by rails 160 to be slidable relative to the printing device 100 in the direction of arrow C from the state shown in FIG. 2(a), so that the front discharge storage section 29 can be stored within the printing device 100 (device main body). These mechanisms allow the first holding member 130 to rotate to change the position of the first holding member 130 and the second holding member 140 when the basket cloth 120 receives a discharged sheet (receiving position), and the position of the first holding member 130 and the second holding member 140 when the basket cloth 120 is stored in the printing device 100 (storage position). Accordingly, the position of the drawer section 150 in the receiving position (receiving position) and the position of the drawer section 150 in the storage position (storage position) can be changed. The first position is the position of the first holding member 130 when the side rod 131 rotates toward the device body and the first holding member 130 is located within the drawer section 150 together with the side rod 131. The second position is the position of the first holding member 130 when the side rod 131 is erected at a predetermined angle, so that the first holding member 130 is higher than the drawer section 150. 1(a) shows a state in which the first holding member 130 is in the first position, the second holding member 140 is removed from the vicinity of the discharge port, the second holding member 140 and the basket cloth 120 are stored in the drawer section 150, and the drawer section 150 is in the storage position. At this time, the basket cloth 120 is, for example, folded and stored in the drawer section 150, and the entire basket cloth 120 is stored in the drawer section 150.To use the basket cloth 120, as shown in FIG. 1(b), the drawer section 150 is pulled out from the device body, the basket cloth 120 is removed from the drawer section 150, the first holding member 130 is set to the second position, and the second holding member 140 is fixed near the discharge port. At this time, the drawer section 150 remains pulled out from the device body. The printing device 100 of this embodiment is configured to accommodate the basket cloth 120 in the storage configuration shown in FIG. 7 in addition to the storage configuration shown in FIG. 1(a). While FIG. 7 shows an embodiment in which only a portion of the basket cloth 120 is stored in the drawer section 150, changing the orientation of the receiving surface of the basket cloth 120, as opposed to the storage configuration shown in FIG. 1(a). In this way, this embodiment allows the user to select the storage configuration of the basket cloth 120 at their own discretion. Details of each configuration are provided below.

[0013] When the basket is not in use, dust accumulates if the basket cloth 120 is exposed with the receiving surface facing upward. When dust accumulates in the basket, it can come into contact with ejected printed materials, potentially causing scratches. Furthermore, a person's foot or an object could get caught in the hanging basket, damaging the basket itself or the parts that hold the basket, or even causing injury. Another issue is the poor appearance when installed in an office or other space. However, if the basket cloth 120 can be removed and placed in the drawer section 150 and stored inside the printing device 100 as in this embodiment, it can be removed and used as an ejected paper storage section only when needed, thereby solving these issues.

[0014] When discharging paper to the front side of the printing device, the drawer section 150 is pulled out from the printing device to the most exposed position (receiving position), the side rod 131 is in an upright position as shown in FIG. 6, and the first holding member 130 and the second holding member 140 are arranged (receiving arrangement) so that the receiving surface of the basket cloth 120 faces upward. At this time, the side rod 131 leans forward by its own weight against a stopper (not shown) provided at the rotation center 251, since the first holding member 130 is located in front of the printing device relative to the rotation center. The position where the first holding member is above the drawer section 150 is called the second position. The first holding member 1 When a strong external force is applied to the side rod 131 in the forward direction, the side rod 131 bends and comes into contact with the front wall of the drawer section 150, so that the force is received by the highly rigid drawer side, preventing damage.

[0015] When the drawer unit 150 is pulled out, a predetermined space is provided between the lower bottom surface 51 of the drawer and the floor 52. A gap Z is provided in this predetermined space so that a person's toes can fit in. In this embodiment, as an example, the gap Z is approximately 85 mm. When the drawer unit 150 is pulled out and protruding, the user would normally have to stand in a position lower by the distance of the drawer unit 150, making it difficult to approach the front of the printing device. However, by providing the gap Z in this manner, the user can insert their toes under the drawer unit 150, so that even when standing in front of the printing device to operate the panel, etc., adverse effects on operability can be minimized.

[0016] 2(b) and 2(c) show the configuration of the basket cloth 120. This basket cloth 120 is detachably attached to the first holding member 130 and the second holding member 140. The proposed basket cloth 120 has at least one hook-and-loop fastener 121 in the width direction of the sheet 1, and the user wraps the basket cloth 120 around the two holding members at the installation site to fasten each pair of hook-and-loop fasteners 121. Here, a pair of hook-and-loop fasteners 121 are attached to the basket cloth 120, but this is not the only example. One of the hook-and-loop fasteners 121 may be attached to the second holding member 140, and the other hook-and-loop fastener 121 may be attached to the basket cloth 120 (FIG. 2(d)). Because this configuration uses a two-tiered sheet feeder 200, the lowest level is used to provide a front discharge storage section 29 that can also store the first holding member 130, but this configuration is not limited to this. For example, if the printer device is a single-stage upper roller specification as shown in FIG. 2(e), the side rod 131 may be configured to be rotatable in and out of the printer device 100 in the space where the lower stage roller was located inside the printer device 100 without using the drawer section 150.

[0017] Continuing with Figure 3, the configuration of the second holding member 140 will be described. The second holding member 140 has positioning members 141 on both ends that determine the position of the basket cloth 120. These two positioning members 141 are configured to be detachable from the front discharge guide unit 110 near the discharge outlet of the printing device. By making them detachable, the second holding member 140 can be fixed in place when the basket cloth 120 is in use, and can be removed and moved to another location when the basket cloth 120 is not in use.

[0018] 4(a) through 4(d) will further explain the guide configuration when the second holding member 140 is installed in the printing device 100. The front paper ejection guide 110 described above is composed of an upstream paper ejection guide 111, a downstream paper ejection guide 112, and the second holding member 140. The positional relationship between the underside of the upstream paper ejection guide 111 and the downstream paper ejection guide 112 is such that they overlap horizontally (dashed line D) and a vertical space E is formed. The downstream paper ejection guide 112 overlaps horizontally, but the entire paper ejection guide section is not horizontal; it has an inclined shape 112a that slopes downward at a predetermined angle relative to the horizontal in the paper ejection direction. In this proposal, the inclination is 17 degrees. As shown in FIG. 4(c) (FF cross section of FIG. 1(b)), the basket cloth 120 has a first set position, which is the receiving orientation for installation in the printing device 100, with the second holding member 140 inserted into the space E. In this case, the second holding member also has a cross-sectional shape consisting of a horizontal surface 140a and an inclined surface 140b in a cross-sectional view along arrow G, following the space E and the inclined shape 112a, and has hemmed portions 140c in the longitudinal direction on both the upstream and downstream sides of the paper discharge direction. This configuration achieves both space saving and strength. Furthermore, in this first set position, the second holding member 140a overlaps horizontally below the upstream paper discharge guide 111, preventing curled sheets 1 from getting caught on the basket cloth 120 even when discharged in the direction of arrow K.

[0019] The engaging member (described below) that engages with the second holding member 140 is attached to the upper roll cover 201, allowing the basket cloth 120 to be opened and closed when the basket cloth 120 is in the first set position. Therefore, roll paper can be replaced without removing the basket cloth 120. Furthermore, in the first set position, the basket 120 covers the front of the printing device 100, preventing scratches and ink stains caused by contact with curled sheets. As shown in FIG. 4(a), the width Wf of the basket cloth 120 is larger than the maximum width Wp of the sheet 1 specified in the printing device specifications. Even when ejecting a sheet of the maximum width specified in the printing device specifications, the sheet 1 does not extend beyond the width of the basket cloth 120, as shown in FIG. 1(b). Furthermore, because the width Wf of the basket cloth 120 is large enough to fit inside the user operation units 141b at both ends (described below), the width of the sheet 1 is necessarily inside the hook portions 141a.

[0020] 5(a), (b), and (c) will be used to provide a detailed description of the positioning members 141 that engage with the downstream discharge guides 112 provided on both ends of the second holding member 140. These positioning members 141 are configured to engage with the printing device 100 outside the maximum sheet width specified in the specifications when in the first set position, and this engagement portion 114 is located inside the length of the downstream discharge guide in the discharge direction. This configuration provides good visibility and easy access for the user.

[0021] Additionally, the outer side of the engagement portion 114 is formed with a slope 114a that increases in the sheet width direction as the sheet advances in the paper ejection direction. This serves as a guide when the user installs the positioning member 140. The positioning member 141 is formed with a hook portion 141a for engaging with the engagement portion 114. The second holding member 140 can be installed by engaging this hook portion 141a with a protrusion 114b made of the same material on the engagement portion 114 at a position lower than the paper ejection guide surface. Furthermore, a user operation portion 141b is provided above the hook portion 141a during installation. This makes it easy to recognize the hook position and also prevents the second holding member 140 from falling out of the space E between the upstream paper ejection guide 111 and the downstream paper ejection guide 112 and into the interior of the printing device 100. The total length of the second holding member 140, including the positioning members 141 at both ends, is configured to be shorter than the distance between the inner surfaces of the drawer portion 150 below the printer in the sheet width direction. Therefore, when not in use, it can be stored in the drawer section 150 in the same way as the first holding member 130.

[0022] Figure 6 is a side view of the cross section of the paper storage section. When the various components are set up to allow paper to be ejected, the basket cloth 120 contacts the bottom surface 50 of the drawer section 150. This allows the bottom surface 50 of the drawer section 150 to function as a support surface separate from the first holding member when paper is ejected onto the basket cloth, allowing the drawer to support the paper's weight. This reduces the load on the first holding member 130 and the second holding member 140 due to the weight of the paper ejected, simplifying the configuration. Specifically, as described above, the first holding member 130 leans toward the front of the printing device under its own weight, eliminating the need for a locking mechanism to maintain its position. When the basket cloth and the drawer bottom surface 50 are not in contact, the weight of the paper ejected falls on the first holding member 130 and the second holding member 140. Without a locking mechanism, the first holding member 130 would rotate in the direction of arrow B from the position shown in Figure 2(a) when a certain weight is applied. Possible solutions to this problem include adding a locking mechanism or tilting the side rod 131, but either approach would result in new problems, such as increased costs and an increased installation area for the device. Similarly, on the second holding member 140 side, a load is applied to the protrusion 114b with which the hook portion 141a engages, so measures such as changing the material of the protrusion to one with a higher load capacity are necessary. However, by keeping the basket cloth in contact with the bottom surface of the drawer, the load on the first holding member 130 and the second holding member 140 can be reduced, resulting in a simple and inexpensive configuration. In this embodiment, the basket cloth 120 is configured to contact the bottom surface 50 of the drawer before paper is ejected when the basket is set, but a similar configuration would be possible where the contact does not occur at this stage, but occurs when the basket 120 bends after paper is ejected. The effect is obtained.

[0023] As shown in Figure 6(a), a gap 250 is provided between the upper roll cover 201 and the lower roll cover 202. This clearance is necessary when the upper and lower roll covers rotate together to open and close. If the basket cloth 120 is not attached, the sheet 1 unwound from the roll will move downward, rubbing its leading edge against the upper roll cover due to its curling tendency. When it reaches the gap 250, the leading edge of the sheet 1 is caught in the gap 250, which functions as a stop for the sheet 1. As shown by the sheet 1 (solid line) in Figure 6(b), the curl causes the sheet to bulge, leaving its leading edge in the gap 250. The sheet is then ejected as shown by the sheet 1 (dashed line) in Figure 6(b), with its leading edge inserted into the gap. The printed surface of the inserted leading edge comes into contact with the lower roll cover, resulting in scratches on the printed surface. As shown in Figure 6(a) in this embodiment, when a basket cloth is placed in front of the gap 250, the leading edge of the sheet 1 advances while pressing its leading edge against the upper roll cover 201 via the basket. Because a portion of the basket cloth 120 deforms into a concave shape, when the leading edge of the sheet reaches the gap 250, the basket cloth 120's flexibility pushes it into the gap 250, causing the leading edge to curl, just as it would if the basket cloth were not attached. However, because the basket cloth 120 is present between the print surface and the gap 250 or the lower roll cover 202, there is no direct contact between the print surface and a rigid body. Furthermore, if the sheet 1 curls on the paper ejection guide, it can cause paper lift near the head, rubbing against the print surface and the head, resulting in scratches. However, the risk of paper lift is low once the leading edge of the sheet has passed the paper ejection guide and exited the front of the printing device. Furthermore, in this embodiment, the leading edge of the sheet curls only after reaching the gap 250 below the upper roll cover 201, preventing paper lift. By rolling the paper in the discharged paper storage section in this way, the paper's posture can be stabilized when stored. Also, by rolling the paper, storage efficiency is improved, and more paper can be discharged and stored.

[0024] Figure 7 is a cross-sectional view of the first holding member 130 when it is rotated toward the printer body without being removed from the printer, closing the drawer section 150. The state of the basket cloth 120 at this time is indicated by a dashed line. Let L1 be the distance along the exterior from the first holding member 130 to the top edge 150a of the drawer, L2 be the distance from the top edge 150a of the drawer to the first holding member in the retracted state, and L3 be the length of the basket cloth 120 in the ejection direction. The relationship L3 > L1 + L2 is established. The retracted state of the first holding member 130 refers to a state in which the first holding member 130 is retracted in a position where it will not hit any components of the printer body even if the drawer 150 is pulled out. In Figure 7, the first holding member 130 is positioned at its highest point in the retracted state. This configuration prevents the first holding member 130 from coming into contact with components on the printer body, even when the drawer section 150 is closed without removing it from the printer. The tensioned basket cloth 120 causes the first holding member to rotate around the pivot point 251, preventing it from coming into contact with components on the printer body. This allows the drawer section 150 to be opened and closed smoothly. Figure 7 shows a configuration in which the entire receiving member is not housed, as in Figure 1(a). Instead, the receiving surface of the exposed portion of the basket cloth 120 faces sideways, while the receiving surface of the portion of the basket cloth 120 inside the housing faces downward. In this way, Figure 7 allows the receiving surface of the basket cloth 120 to be oriented other than upward without removing the second holding member 140 while it remains fixed near the discharge port. This configuration also prevents dust and other particles from adhering to the receiving surface of the basket cloth 120. Therefore, this configuration is more easily implemented than Figure 1(a) to prevent dust and other particles from adhering to the basket cloth 120. In the embodiment of FIG. 7, the basket cloth 120 is installed on the front of the device body. Therefore, when it is necessary to access the device from the front of the device body, for example, to change the paper feed unit inside the device, the configuration is changed to accommodate the entire receiving member as shown in FIG. 1(a). In this way, the user can freely change the configuration of the basket cloth 120 depending on the purpose of use. Note that the drawer section 150 may be closed with the second holding member accommodated in it.

[0025] Furthermore, the position of the receiving member in which the receiving surface does not face upward in the storage arrangement is shown in this embodiment only as an example, and various other positions and storage configurations may be adopted as long as it is guaranteed that at least dust will not accumulate on the receiving surface.
