The following describes in detail the 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 should be changed as appropriate depending on the configuration and various conditions of the device to which the invention is applied. In other words, it is not intended to limit the scope of the present invention to the embodiments described below.

Figures 1 to 10 are explanatory diagrams of a recording device (hereinafter, printing device) according to a first embodiment of the present invention. The printing device of this embodiment is an example in which the present invention is applied to an inkjet printing device. The printing device of this embodiment includes a supply device (supply section) for supplying a sheet as a recording material from a roll sheet (roll paper), and a printing section (recording section) for printing (recording) an image on the sheet. Furthermore, the printing device of this embodiment includes a storage device that allows the user to store any storage item directly below the roll sheet holding section that holds the roll sheet.

Figure 1(a) is a schematic perspective view showing the front of a printing device 100 that can hold two rolled sheets, which are sheets wound into a roll, as a storage form for recording material. An image is printed on a sheet that is selectively pulled out from two roll sheets set in sheet supply devices 200 arranged above and below. Once printed, the sheet is ejected from a front ejection guide unit 110 provided on the front of the printing device. Using various switches on the operation panel 2, the user can specify the sheet size, switch between online and offline, and input various commands to the printing device 100.

Figure 1(b) is a schematic perspective view of the open storage device 300, which is an optional storage section that can be opened and closed and is disposed under the sheet supply device 200. The storage device 300 is configured to be slidable and withdrawn from the front side of the printing device 100. The user withdraws the storage device 300 and places an optional object in the storage section 302 of the storage device 300, so that the object is stored in the printing device. The storage device 300 has a storage section 302 that can hold an optional object, and a storage device cover 301 that is an exterior surface (outer surface) that forms part of the device side surface 101a on the front side. The stored object can be, for example, a device manual, a spool member, a basket member that is attached to the exterior of the device and that stores discharged sheets, etc.

FIG. 2 is a schematic partial cross-sectional view of the main part of the printing apparatus 100 during front sheet ejection. Two sheet supply devices 200 corresponding to two roll sheets R are arranged one above the other. The sheet 1 drawn from the roll sheet R by the supply devices 200 is transported by a sheet transport unit (transport mechanism) 103 to a printing unit 400 capable of printing an image. 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 an ejection port using an ejection energy generating element such as an electrothermal conversion element (heater) or a piezoelectric element. When an electrothermal conversion element is used, the ink is bubbled by the heat generated, and the ink can be ejected from the ejection port by utilizing the bubble energy. The print head 18 is not limited to an inkjet type, and the printing type of the printing unit 400 is not limited to a serial scan type or a full line type, for example. In the case of a serial scan type, the conveying operation of the sheet 1 and the print head 1 in a direction intersecting the conveying direction of the sheet 1 are performed.
In the case of the full line method, an image is printed by using a long print head 18 extending in a direction intersecting the conveying direction of the sheet 1, and an image is printed while the sheet 1 is conveyed continuously.

The roll sheet R has a shape in which the sheet 1 is wound so as to have a hollow hole (hollow hole). A shaft-shaped spool member 2 is inserted (passed through) into the hollow hole of the roll sheet R, and the spool member 2 is driven to rotate forward and backward by a roll drive motor (not shown). As a result, the roll sheet R is held at its center and rotated forward and backward in the directions of the arrows C1 and C2. The supply device 200 is equipped with a drive unit 3, an arm member (moving body) 4, an arm rotation shaft 5, a first sheet sensor 6, a swinging member 7, driven rotation bodies (pressure contact bodies) 8 and 9, a separation flapper (upper guide body) 10, and a flapper rotation shaft 11. In this embodiment, the supply device 200 is provided in two stages, upper and lower, with the same configuration.

The conveying guide 12 guides the front and back sides of the sheet 1 drawn from the supply device 200 and leads the sheet 1 to the print section 400. The conveying roller 14 is rotated forward and backward by a conveying roller drive motor (not shown). The nip roller 15 can be rotated in response to the rotation of the conveying roller 14, and can be moved toward and away from the conveying roller 14 by a nip roller separation motor (not shown), and the nip force can be adjusted. The conveying roller 14 is rotated when the second sheet sensor 16 detects the leading edge of the sheet 1. The conveying speed of the sheet 1 by the conveying roller 14 is set higher than the drawing speed of the sheet 1 by the rotation of the roll sheet R, so that the sheet 1 can be given back tension and conveyed in a taut state. As a result, slackness of the sheet 1 can be prevented, and the occurrence of creases and conveyance errors in the sheet 1 can be suppressed.

The platen 17 of the printing unit 400 sucks the back surface of the sheet 1 through the suction hole 17a by the negative pressure generated by the suction fan 19. This allows the position of the sheet 1 to be regulated so that it fits along the platen 17, enabling the print head 18 to print an image with high precision. The cutter 20 cuts the sheet 1 on which the image has been printed. The sheet 1 on which the printing has been completed is guided and discharged from the paper discharge port (discharge port) 104 provided on the front part (front side surface) 101a of the printing device housing 101 to the front paper discharge guide part (discharge part) 110. The cover 41 of the rotating door part 400 prevents the sheet 1 on which the image has been printed and discharged from the paper discharge port 104 from returning to the supply device 200 (the storage part for the roll sheet R) below the paper discharge port 104.

Figure 3 is an explanatory diagram of the paper discharge form of the printing device 100 when the pivot door unit 500 is closed. The printed sheet 1 is discharged from the paper discharge support unit 40 provided on the front paper discharge guide unit 110 provided on the device side 101a on the front side of the printing device, and is guided downward along the roll cover 41. Here, the paper discharge support unit 40 and the roll cover 41 are configured to overlap in the Y direction so that the leading edge of the discharged sheet 1 does not get into the gap between the paper discharge support unit 40 and the roll cover 41. In addition, the roll cover 41 has a surface that is continuous and has no gaps in the Z direction when the pivot door unit 500 is closed, so that the leading edge of the discharged sheet 1 does not get caught by the cover 41. In addition, when the pivot door 500 is in the closed state, it is oriented along the device side surface 101a, and the roll temporary placement table 42, which is the inner surface, faces horizontally against the roll sheet R in the storage section of the supply device 200, and holds the roll sheet R in a predetermined holding position.

4A is an explanatory diagram of the configuration of the rotating door part 500 when the roll sheet R is placed on it. The roll temporary placement table 42 has a surface in the sheet width direction, and can place a roll sheet R of any width equal to or less than the width of the rotating door part 500 and a roll sheet R with the spool member 2 attached thereto. A uniform recess 42a is provided on this surface in the sheet width direction, and the roll sheet placed in the recess 42a is stabilized by its own weight. The roll temporary placement table 42 also has a guide part 42b facing the supply device 200. This guide part 42b is continuous from the recess 42a, and guides the setting of the roll sheet R to the supply device 200 by supporting the flange outer shape of the spool member 2 when the roll is set.

The spool member 2 is an auxiliary member that is attached integrally to the rolled sheet R and assists in holding the rolled sheet R in the supply device 200, and is rotatably supported in the supply device 200. The spool member 2 includes a spool shaft 21 as the shaft portion, a reference side spool flange 23 as the reference side flange portion, and a non-reference side spool flange 24 as the non-reference side flange portion (see FIG. 6(a)).

When the rotating door section 500 is open, the roll temporary placement table 42 protrudes from the front of the device. That is, when the rotating door section 500 is open, it protrudes horizontally from the side surface 101a of the device, and the roll temporary placement table 42, which is the inner surface of the rotating door section 500, opens upward. Therefore, the spool member 2 can be inserted from the side into the roll sheet R placed on the roll temporary placement table 42. This allows the user to set the spool member 2 on the roll sheet R without having to prepare a new setting space, such as a desk, for setting the spool member 2.

4(b) is an explanatory diagram of the operation of sliding the roll sheet R with the spool member 2 from the roll temporary placement table 42 to the spool holder 31 of the supply device 200 when the rotating door section 500 is in the open state in the first embodiment. The arrow T1 indicates the trajectory of the center of the roll sheet R to be slid. When the rotating door section 500 is in the open state, the guide section 42b overlaps with the spool guide 13 as the second guide section in the Y direction. In addition, in the overlapping section, the Z direction distance between the guide section 42b and the spool guide 13 is approximately equal to the distance from the outer shape of the spool flanges 23, 24 of the spool member 2 to the outer shape of the spool shaft 21. In other words, the height of the shaft guide surface of the guide section 42b is approximately equal to the height from the lower end of the spool flanges 23, 24 to the lower surface of the spool shaft 21 as the shaft section. Furthermore, the outer shape of the spool flanges 23, 24 is configured to be larger than the diameter of the roll sheet R.

Figure 5 is an explanatory diagram of the rotation of the roll sheet holding part 105 when the roll sheet is set. The positional relationship between the driven rotors (pressure contact bodies) 8, 9 and the arm member (moving body) 4 and the roll sheet R when the roll sheet R is slid and set will be described in detail. Figure 5 (a) shows the case when the remaining amount of the roll sheet R is small, and Figure 5 (b) shows the case when the remaining amount of the roll sheet R is large. In the roll sheet R storage part of the supply device 200, the arm member 4 is configured to be rotatable around the arm rotation shaft 5 (see Figure 2) and is provided so as to be movable (rotatable) up and down together with the driven rotors 8, 9 according to the outer diameter of the roll sheet R. As a lower guide body, the arm member 4 guides the lower surface of the sheet 1 unwound (pulled out) from the roll sheet R on the downstream side of the sheet unwinding rotation direction of the roll sheet R from the pressure contact position between the driven rotors 8, 9 and the outer peripheral surface of the roll sheet R. The driven rotors 8 and 9 are provided with a rotating member 54 that forms an inclined surface that slopes downward toward the upstream side at the upstream end of the guide direction when the rolled sheet R is guided to the storage section of the supply device 200. When the rolled sheet R is set in the rolled sheet holding section 105, the tip side of the rolled sheet holding section 105 is lowered downward, and as shown in FIG. 2, etc., at least a part of the rolled sheet holding section 105 is in a position where it protrudes downward from the rotating door section 500.

5A, when the driven rotors (pressure contact bodies) 8 and 9 are in the initial position and a roll sheet R51 with a small remaining amount is slid and set, the driven rotors (pressure contact bodies) come into contact with the rotatable member (movable part) 54 at the tip of the driven rotors (pressure contact bodies).Then, the driven rotors (pressure contact bodies) 8 and 9 are moved to the set position while pushing down the rotatable member 54 at the tip of the driven rotors (pressure contact bodies).

In FIG. 5(b), when a roll sheet R52 with a large remaining amount is slid and set, it comes into contact with a rotatable member 54 at the tip of the driven rotor (pressure contact body). The rotatable member 54 at the tip of the driven rotor (pressure contact body) rotates by itself, and then pushes down together with the driven rotors (pressure contact bodies) 8 and 9, moving to a position where it presses the roll sheet R. After guiding the roll sheet, the member 54 is configured to return to its original position (angle) by a spring (not shown) or the like. Note that the member 54 may be configured to be fixed to the driven rotors (pressure contact bodies) 8 and 9.

Figure 6 is an overall view of the roll sheet protection unit 600 of this embodiment 1. Figure 6(a) is a front view with the lower pivot door unit open, and Figure 6(b) is a top view of a partial cross section of the roll sheet protection unit 600.

As shown in Figures 6(a) and 6(b), the roll sheet protection part 600 is a long member that is provided to bridge from one end of the storage part 302 to the other end in the horizontal direction (X direction) perpendicular to the opening/closing movement direction (Y direction) of the storage device 300. The roll sheet protection part 600 may be made of, for example, sheet metal. Both ends of the roll sheet protection part 600 are fixed to the device housing 101 by the left and right rigid parts 920, 930 in the X direction, are wider than the roll sheet R, and are positioned directly below the roll sheet R.

The placement conditions of the roll sheet protection unit 600 are explained in Figure 7. Figure 7 is a diagram showing the placement conditions of the roll sheet protection unit 600, with Figure 7(a) showing the placement conditions in the front-to-back direction (horizontal direction) and Figure 7(b) showing the placement conditions in the up-down direction.

As shown in FIG. 7(a), in the front-to-back direction (horizontal direction), the tip of the roll sheet protection unit 600 is positioned further forward of the printing device than the center point of the roll sheet R. Also, as shown in FIG. 7(b), in the up-down direction, the bottom surface of the roll sheet protection unit 600 is positioned lower than the lowest point of the arm member 4 in the roll sheet holding unit 105 and higher than the upper end of the storage unit 302 of the storage device 300.

The storage process when storing an item 700 that exceeds the maximum loading height will be described using Figure 8. Figure 8 shows the process of storing an item in this embodiment, with Figure 8(a) showing the state before storage and Figure 8(b) showing the state after storage.

In this embodiment, the opening where the storage device cover 301 of the storage device 300 opens and closes has its upper end opened higher than the lowest point of the arm portion 4 of the roll sheet holding portion 105, and is configured to be able to store the stored object 700 that is higher than the height of the storage portion 302. In such a case, if the storage device 300 is slid to the closed position (storage completion position) as it is, there is a concern that the stored object 700 will come into contact with the arm portion 4, causing damage to the arm portion 4 or the roll sheet R. In order to avoid such contact, the roll sheet protection portion 600 functions as a regulating portion that regulates the storage position of the stored object 700 or regulates the storage device 300 from sliding to the closed position. For example, when there is a space in the storage portion 302 of the storage device 300 where the stored object 700 can move and the stored object 700 can rotate, the position of the stored object 700 is changed to a position that does not contact the arm portion 4, etc. That is, as shown in FIG. 7B, when the storage device 300 is stored in the printing device, the stored object 700 comes into contact with the roll sheet protection part 600, and is turned around to a position 701, and is arranged to be stored in the storage part 302. This allows the stored object 700 stored in the storage device 300 to be stored in the printing device without damaging the roll sheet R or the roll sheet holding part 105 (the arm part 4, etc.). Note that, as will be described in detail later, by using a regulating part such as the roll sheet protection part 600, the configuration is simpler than, for example, a configuration in which the storage device 300 and the supply device 200 are completely separated by a single plate. In addition, the space in which the arm member 4 moves can be secured. That is, a layout in which the supply device 200 and the storage device 300 arranged above and below are completely separated by a simple horizontal plate is also conceivable, but such a layout creates a lot of dead space, which leads to an increase in the size of the device. As in this embodiment, by arranging the roll sheet protection part 600 as a partial partition in the minimum necessary location taking into account the balance between the movable area of the arm member 4 and the storage space in the storage device 300, it is possible to miniaturize the device and save space.

In addition, when the height of the stored object is higher than the height from the bottom surface of the storage device 300 to the roll sheet holding part 105 and the stored object cannot rotate (change its posture) in the storage part 302, the stored object is caught by the roll sheet protection part 600, and the closing operation of the storage device 300 is restricted. This prevents a tall stored object from being stored inside the printer, and prevents damage to the roll sheet R or the roll sheet holding part 105 (arm part 4, etc.) due to contact with the stored object. In addition, since the closing operation of the storage device 300 is restricted at a position where the storage device cover 301 is not completely closed due to the stored object being caught by the roll sheet protection part 600, it is expected to have the effect of encouraging the user to check the storage state of the stored object. This is also the case when the height of the stored object is higher than the height of the opening of the device housing 101 through which the storage device cover 301 opens and closes. In other words, if the contents get caught in the opening, the closing operation of the storage device 300 is restricted to a position where the storage device cover 301 is not completely closed, which prompts the user to check the storage status of the contents.

The configuration of the roll sheet protection unit 600 in the first embodiment will be described with reference to FIG. 9. FIG. 9(a) is a perspective view of the roll sheet protection unit 600 in this embodiment, FIG. 9(b) is a partial cross-sectional view thereof, and FIG. 9(c) is a partial cross-sectional view of the roll sheet protection unit 601 in the second embodiment of the present invention. As in the cross-sectional shape of FIG. 9(a), by configuring the bend perpendicular to the sliding direction (horizontal direction) of the storage device 300, the contact with the stored object is surface contact by a regulating surface perpendicular to the moving direction of the stored object. In this way, it is possible to change the posture (rotation operation) of the stored object without damaging the stored object. In addition, as in the roll sheet protection unit 601 shown in FIG. 9(b) which is the second embodiment of the present invention, it is also preferable to have a bent shape of, for example, 135° with respect to the sliding direction (horizontal direction) of the storage device 300 (stored object), so that the contact with the stored object is an inclined surface contact. By such an inclined regulating surface, the stored object is gently fallen, making it possible to rotate the stored object more stably. The angle of the regulating surface of the roll sheet protection unit 600 is preferably set in the range of 90° to 135°, for example, but is not limited to the above range and is set appropriately depending on the storage space of the storage unit and the positional relationship with the roll sheet holding unit 105, etc.

The configuration of the roll sheet protection unit 602 according to the third embodiment of the present invention will be described with reference to Figures 10 and 11. Figure 10 is a perspective view of the roll sheet protection unit 602 according to the third embodiment of the present invention, with Figure 10(a) being a component diagram before rotation and Figure 10(b) being a component diagram after rotation. Figure 11 is a top view of the roll sheet protection unit 602 according to the third embodiment of the present invention after installation.

The roll sheet protection part 602 of the third embodiment is composed of a pair of long rotating members, a first regulating part 602a and a second regulating part 602b. As shown in Fig. 10A, the pair of regulating parts 602a, 602b are normally arranged in series (regulated state) and function as a single regulating part similar to the roll sheet protection parts 600, 6001 of the first and second embodiments. As shown in Fig. 10B, the regulating parts 602a, 602b are provided rotatably about rotation axes (rotation axes) 542, 543 extending vertically to the left and right rigid parts 920, 930 fixed to the device housing 101, respectively. That is, the restricting portion 602a rotates around the rotation shaft 542 on one side in the horizontal direction of the device body, and the restricting portion 602b rotates around the rotation shaft 543 on the other side in the horizontal direction of the device body. The rotation around the rotation shafts 542 and 543 is restricted within a predetermined range, and rotation in the negative direction of the Y axis from the serial arrangement in Fig. 10(a) is restricted, while rotation in the positive direction of the Y axis is permitted as shown in Fig. 10(b). The movement of the storage device 300 from the open position to the closed position (storage completion position) is in the negative direction of the Y axis, and the movement from the closed position to the open position is in the positive direction of the Y axis.

A predetermined gap is provided between the opposing tips of the pair of restricting parts 602a, 602b so as not to impede their rotation. In addition, coil springs (not shown) are attached to the rotating shafts 542, 543 as a return structure for maintaining the arrangement (rotation phase) of the restricting parts 602a, 602b in FIG. 10(a) when no particular external force is applied. Note that the return structure may be any conventionally known structure as appropriate, and is not limited to a specific structure.

For example, when the storage device 300 is opened and the contents come into contact with the roll sheet protection unit 602, the regulating units 602a and 602b rotate about the pivot shafts 542 and 543, and the tip ends of each rotate in the direction of movement of the storage device 300 to the open position. That is, the roll sheet protection unit 602 changes to an open form (non-regulated state) that separates it into two parts. As described below, it is assumed that the user accidentally drops a sheet inside the device, and the sheet is stored and piled up in the storage unit 302, so that the height of the contents in the storage unit 302 becomes higher than the height of the roll sheet protection unit 602. Alternatively, it is assumed that the folds of the folded contents loosen and become higher than the height of the roll sheet protection unit 602. In such a case, it is possible to avoid the pull-out operation (opening operation) of the storage device 300 being hindered by the contents getting caught on the roll sheet protection unit 602.

Figure 11 is a top view of the printing device 100 with the roll sheet protection unit 602 attached to the device body. When the storage device 300 is pulled out from the stored state of the contained items 703 shown by the dotted line in Figure 11, the contained items 703 and the roll sheet protection unit 602 come into contact. At this time, the regulating units 602a and 602b rotate around the pivots 542 and 543 attached to the left and right rigid units 920 and 930, respectively, so that the contained items 703 can be pulled out without getting caught on the roll sheet protection unit 602.

Figures 12 and 13 are explanatory diagrams of a printing device according to a fourth embodiment of the present invention. Note that matters in this embodiment that are not specifically described here are the same as those in the above embodiment, and so description thereof will be omitted.

Figure 12(a) is a schematic cross-sectional view of the main parts of the printing device 100 according to this embodiment during front discharge. Using Figure 12(a), we will explain the falling of a sheet. For example, if a user drops a sheet from the platen 17, the sheet will pass through the paper passage path 808 indicated by the arrow in the figure and fall to the chassis bottom 900 in the device frame. This paper passage path 808 is a path (discharge path) independent of the sheet passage path from the supply device 200 to the printing unit 400, and is a path connecting the printing unit 400 located above the device to the storage device 300 located below the device. The paper passage path 808 includes a vertical path 809 that extends vertically between the printing unit 400 and the storage device 300, and a horizontal path 810 that connects the chassis bottom 900, which is the bottom part downstream of the vertical path 809, to the storage device 300 in the horizontal direction. The discharged items, such as the fallen sheets described above, are discharged to the storage section 302 of the storage device 300 via the paper path 808.

In the printing apparatus of this embodiment, an overlapping portion 901 that guides a fallen sheet to the storage unit 302 of the storage device 300 is provided on the chassis bottom 900 of the paper passage path. The overlapping portion 901 is configured to guide a sheet that has fallen vertically on the paper passage path of the chassis bottom 900 horizontally and slide it into the storage unit 302 of the storage device 300. This makes it possible to remove the fallen sheet from the storage device 300.

Figure 12(b) is a top view of a partial cross section of the printing device 100 according to this embodiment. When viewed vertically (top-bottom), the chassis bottom 900 has an overlapping portion 901 that partially overlaps the storage portion 302. That is, the overlapping portion 901 causes the horizontal path 810 to overlap horizontally above the storage portion 302. Note that the configuration of the overlapping portion 901 is not limited to the single plate configuration shown in Figure 12, and may be, for example, a configuration in which multiple ribs extending in the paper passage direction are arranged in parallel in the paper passage path width direction.

Using FIG. 13, we will explain the countermeasure configuration when a fallen sheet does not reach the storage device 300 and remains on the chassis bottom 900. FIG. 13(a) is a schematic diagram showing the sheet pushing configuration in the fourth embodiment of the present invention, and FIG. 13(b) is a perspective view of the printing device of this embodiment showing an opening 800 that opens on the back side of the printing device. As shown in FIG. 13(a), the printing device of this embodiment has an opening 800 that opens the paper passage path to the outside of the device. The opening 800 opens near the chassis bottom 900 of the vertical path 809. The user can push the fallen sheet from the opening 800 into the storage section 302 of the storage device 300 using any rod-shaped object.

Figure 14 is a schematic cross-sectional view illustrating the inclined portion of the chassis bottom 900 in the fifth embodiment. As a frame shape at the rear of the printing device 100, an inclined portion 902 is provided on the upper surface of the chassis bottom 900, which descends toward the storage section 302 of the storage device 300. The presence of such an inclined portion 902 makes it easier for fallen objects such as sheets that fall into the paper path to slide down the slope of the inclined portion 902 and enter the storage section 302 of the storage device 300.

In addition, in the fourth and fifth embodiments, in order to more reliably accommodate the fallen object in the accommodation section 302 of the accommodation device 300, it is preferable that the surfaces of the overlap section 901 and the inclined shape section 902 are smooth and free of protrusions such as screws.

The above embodiments can be combined with each other as long as no technical contradictions arise.
