Description

Technical Field

[0001] This disclosure relates to a printing apparatus. Background Technology

[0002] Patent Document 1 discloses an image forming apparatus having an operation panel, which has a display section and a speaker disposed on the side of the display section.

[0003] In patent document 2 Figure 5 Figure 8 shows an image forming apparatus having a speaker on the back side of a liquid crystal panel, the speaker emitting sound toward the back side of an operating device having the liquid crystal panel.

[0004] Patent document 3 discloses an electronic device having an operating part that can be housed in a storage section by means of a tilting mechanism.

[0005] In the image forming apparatus described in Patent Document 1, the display unit and speaker are arranged horizontally, thus limiting the screen size of the display unit. On the other hand, as described in Patent Document 2, if the speaker is placed on the back side of the liquid crystal panel, the screen size can be further increased, thereby improving usability. However, when the structure of Patent Document 2, which emits sound towards the back side, is applied to the operation unit disclosed in Patent Document 3, the sound tends to be muffled inside the storage compartment. As a result, the sound emitted from the speaker becomes weak, potentially making it difficult for the user to hear the sound. In cases where it is difficult to hear the sound from the speaker, the user sometimes needs to use a tilting mechanism to lift the operation unit out of the storage compartment, which may reduce usability.

[0014] Hereinafter, the printing apparatus 1 of this embodiment will be described with reference to the accompanying drawings. Figure 1 The printing apparatus 1 shown is, for example, an inkjet printer that records images such as text and photographs on a medium M by ejecting ink, which is an example of a "liquid", onto the medium M being transported.

[0015] In the following figures, the dimensions of each component are illustrated differently from their actual size to make them easily identifiable. Furthermore, identical structures are labeled with the same symbols in each figure, and repeated descriptions are omitted. Moreover, the X-axis, Y-axis, and Z-axis are illustrated as mutually orthogonal coordinate axes in each figure, as needed. Arrow markings are placed on the X-axis, Y-axis, and Z-axis. On each of the X-axis, Y-axis, and Z-axis, the direction of the arrow marking is positive, and the direction opposite to the arrow marking is negative.

[0016] For ease of explanation, the positive direction of the X-axis will sometimes be referred to as left or simply left, and the negative direction as right or simply right. Similarly, the positive direction of the Y-axis will sometimes be referred to as front or simply front, and the negative direction as back or simply back. Furthermore, the positive direction of the Z-axis will sometimes be referred to as top or simply top, and the negative direction as bottom or simply bottom.

[0017] Furthermore, the direction parallel to the X-axis is the width direction of the printing apparatus 1, and corresponds to the width direction of the medium M on which the image is recorded. The direction parallel to the Y-axis corresponds to the depth direction of the printing apparatus 1.

[0018] like Figure 1As shown, the printing apparatus 1 of this embodiment includes a first housing 100. A foot frame 7 is mounted near both ends of the first housing 100 along the X-axis. Small casters 13 and an adjuster 14 are provided at the lower part of the foot frame 7. The small casters 13 are used to move the printing apparatus 1. The adjuster 14 is used to properly position the printing apparatus 1 on the mounting surface G. Furthermore, the printing apparatus 1 has a supply section 2 at the rear of the first housing 100, i.e., on the -Y direction side, for holding a roll body R1. The supply section 2 supports the paper tube of the roll body R1 wound with the medium M in a clamping manner along the X-axis direction and supplies the medium M to a position opposite to the head 5.

[0019] The first housing 100 has a receiving portion 101 on its upper surface 100A facing the +Z direction. The upper surface 100A is an example of a "first surface". The upper surface 100A is an XY plane parallel to the X-axis and Y-axis. The receiving portion 101 is configured as a concave shape that is recessed in the -Z direction compared to the upper surface 100A of the first housing 100.

[0020] Furthermore, the printing apparatus 1 includes a display unit 40. The display unit 40 is housed in a storage unit 101. The display unit 40 has a display panel 41 for displaying information such as text and graphics. The display panel 41 has a display surface 41A facing a direction opposite to that of the rear surface 40B of the display unit 40. The display unit 40 can be moved to a first position P1 in the storage unit 101 with the display surface 41A of the display panel 41 facing a first direction that is the outside of the first housing 100, by means of a tilting mechanism (not shown) provided in the printing apparatus 1. Furthermore, the display unit 40 can be moved to a second position P2 where it is erected from the storage unit 101 with the display surface 41A facing a second direction that intersects the first direction. The first direction is, for example, the +Z direction, and the second direction is a tilting direction having a vector component in the +Z direction and a vector component in the +Y direction. The display unit 40 can be fixed at any position between the first position P1 and the second position P2 by means of the tilting mechanism.

[0021] In other words, the display unit 40 can be moved to a first position P1 where the rear surface 40B of the display unit 40 is housed in the housing 101 and a second position P2 where the rear surface 40B of the display unit 40 is exposed from the housing 101. Details about the display unit 40 will be described later.

[0022] Furthermore, while the printing apparatus 1 is conveying the medium M in the conveying direction A, the supply unit 2 causes the roll body R1 to rotate in the rotation direction C. Additionally, although in Figure 1In this process, a roll body R1 is used with the image forming surface M1 facing outwards, but a roll body R1 with the image forming surface M1 facing inwards can also be used. In this case, the supply unit 2 can rotate the roll body R1 in the opposite direction to the rotation direction C to deliver the medium M.

[0023] Furthermore, the printing apparatus 1 has a transport path for the medium M, which is composed of a medium support portion 3 for supporting the medium M. The printing apparatus 1 has an upstream medium support portion 3A, an impression plate 3B, and a downstream medium support portion 3C in sequence from the upstream side to the downstream side in the transport direction A, which serve as the medium support portion 3.

[0024] Furthermore, the printing apparatus 1 is equipped with a roller pair 8 consisting of a drive roller 8A and a driven roller 8B in order to transport the medium M in the transport direction A along the transport path. In addition, the drive roller 8A and the driven roller 8B can also be reversed in terms of their driving and driving relationships.

[0025] Furthermore, the printing apparatus 1 includes: a head 5, which has a nozzle (not shown) at a position opposite the impression plate 3B in the +Z direction, and ejects ink from the nozzle; and a carriage 4, which mounts the head 5 and is capable of reciprocating in the width direction B. The head 5 is an example of a "printing section" for printing on a medium M. A liquid supply channel (not shown), made of a hose or the like, is connected to the head 5, and ink is supplied to the head 5 via the liquid supply channel from an ink cartridge (not shown). In addition, in the printing apparatus 1 of this embodiment, at the position where the impression plate 3B and the head 5 are opposite each other, the transport direction A is the +Y direction, the width direction B, which is the movement direction of the head 5, is along the X-axis, and the ink ejection direction is the -Z direction. In this embodiment, the first housing 100 at least covers the head 5. In this embodiment, the first housing 100 also covers a portion of the upstream media support 3A, the impression plate 3B, and the downstream media support 3C.

[0026] The printing apparatus 1 repeatedly performs the actions of conveying the medium M in the conveying direction A with a predetermined conveying amount, and simultaneously ejecting ink while moving the head 5 in the width direction B with the medium M stopped. However, it is not limited to such a structure, and may also have a structure with a so-called line head that has nozzles for ejecting ink arranged along the width direction B covering the entire width of the medium M, or a structure with a printing section having a heat transfer method, etc.

[0027] Furthermore, a heater 20 is provided on the downstream dielectric support portion 3C to heat the supported surface M2 of the dielectric M opposite to the image forming surface M1. The heater 20 is constructed of heating wires or the like, but is not limited to such a structure. For example, in order to heat the supported surface M2 of the dielectric M opposite to the image forming surface M1, the heater 20 may be provided not only on the downstream dielectric support portion 3C, but also on the upstream dielectric support portion 3A and the imprint plate 3B.

[0028] Furthermore, an air supply section 10 is provided in the portion of the transport path opposite to the downstream medium support section 3C. This air supply section 10 dries the ink ejected from the head 5 onto the image forming surface M1 of the medium M by blowing airflow F. In this embodiment, the air supply section 10 is equipped with a fan 11 that generates airflow F and is capable of supplying gas as airflow F to the image forming surface M1 of the medium M, but it is not limited to such a structure.

[0029] Furthermore, downstream of the downstream media support section 3C in the conveying direction A, a winding section 6 is provided to wind the media M conveyed along the conveying direction A into a roll shape, forming a roll body R2. The media M conveyed from the supply section 2 to the winding section 6 is conveyed along the conveying path under a predetermined tension. The winding section 6 supports the paper tube, which is the core of the roll body R2, in a clamping manner in the X-axis direction, and winds the media M into a roll shape by rotating the paper tube. Although in Figure 1 In this process, the take-up unit 6 winds up the medium M by rotating the roll body R2 in the rotation direction C so that the image forming surface M1 is on the outside. However, it can also wind up the medium M so that the image forming surface M1 is on the inside. In this case, the take-up unit 6 rotates the roll body R2 in the opposite direction to the rotation direction C.

[0030] Furthermore, a guide rod 30 is provided between the downstream medium support portion 3C and the winding portion 6 in the conveying direction A. The guide rod 30 has a contact surface 31 that is arc-shaped when viewed from the width direction B. Moreover, the guide rod 30 guides the conveying of the medium M by contacting the contact surface 31 with the supported surface M2 of the medium M wound by the winding portion 6. However, the structure of the guide rod 30 is not particularly limited, and it is also possible to have a structure without the guide rod 30.

[0031] The printing apparatus 1 has a control unit (not shown). The control unit controls various operations of the printing apparatus 1. Furthermore, the structure of the control unit is not particularly limited, and the control unit may also be an external device such as a computer that can communicate with the printing apparatus 1.

[0032] The printing apparatus 1 with the above-described structure is able to record text, photographs, and other images on the medium M by spraying ink onto the medium M being transported.

[0033] The following is for reference Figure 2 as well as Figure 3 This section will explain the state in which the display unit 40 is either stored or exposed relative to the storage unit 101.

[0034] Figure 2 The diagram shows the display unit 40 displaced to a first position P1 via a tilting mechanism (not shown) provided with the printing apparatus 1. The display unit 40 is housed in the housing 101 with its front surface 40A facing the +Z direction. The display unit 40 has an indicator lamp 48 that displays the control status of the printing apparatus 1 by emitting light. The +Z-facing surfaces of the display unit 40 and the indicator lamp 48 are housed such that they are substantially flush with the upper surface 100A of the first housing 100.

[0035] Figure 3 The diagram shows the display unit 40 displaced to a second position P2 via a tilting mechanism (not shown) provided with the printing apparatus 1. The display unit 40 is rotated in the displacement direction D, thereby exposing itself outward from the storage section 101 in a manner that allows visual confirmation of its front surface 40A when viewed from the +Y direction to the -Y direction. With the display unit 40 displaced to the second position P2, the indicator light 48 can be visually confirmed from all directions (front, back, left, right) of the printing apparatus 1.

[0036] in addition, Figure 3 The display unit 40 shown is in a state where it has been rotated approximately 45° relative to the upper surface 100A of the first housing 100. When the display unit 40 is in this state... Figure 3 In the second position P2 shown, the direction in which the front surface 40A faces is a direction having a vector component in the +Z direction and a vector component in the +Y direction. However, since the display unit 40 can rotate more than 90° relative to the upper surface 100A, the direction in which the front surface 40A faces is not limited to this. For example, the direction in which the front surface 40A faces could also be the +Y direction when the display unit 40 has rotated 90°. Moreover, the direction in which the front surface 40A faces could also be the direction in which the display unit 40 has rotated more than 90°, i.e., a direction having a vector component in the -Z direction and a vector component in the +Y direction, etc. In other words, the direction in which the front surface 40A faces is only required to be a direction having a vector component in the +Y direction.

[0037] The following is for reference Figure 4 as well as Figure 5 The details of the display unit 40 will be explained. Figure 4 as well as Figure 5This indicates that the display unit 40 is positioned relative to the upper surface 100A (see reference). Figure 3 And it has rotated approximately 90°. Furthermore, in Figure 5 In the illustration, the side where the front surface 40A is located when viewed from the rear surface 40B of the display unit 40 is shown as the front surface side FS, and the side where the rear surface 40B is located when viewed from the front surface 40A of the display unit 40 is shown as the rear surface side RS.

[0038] like Figure 4 As shown, the display unit 40 also includes a sound output unit 42. The sound output unit 42 includes a buzzer 42A and a speaker 42B. Figure 4 In the view, the sound output unit 42 is arranged overlapping the display surface 41A of the display panel 41, and is positioned on the -Y direction side relative to the display panel 41. By arranging the sound output unit 42 relative to the display panel 41 in this way, the display screen size of the display unit 40 can be further increased, thereby improving usability related to visual confirmation.

[0039] like Figure 5 As shown, the display unit 40 internally includes a display panel 41, a sound output unit 42, a thin sheet component 43, a substrate 44, and a metal plate 45. The display unit 40 also includes: an operation button 47 for inputting predetermined instructions required for controlling the printing apparatus 1; an indicator lamp 48 for displaying the control status of the printing apparatus 1 by emitting light; and a second housing 46, which is an external component of the display unit 40. The second housing 46 includes a front housing 46A and a rear housing 46B. The second housing 46 houses the display panel 41, the sound output unit 42, the thin sheet component 43, the substrate 44, and the metal plate 45.

[0040] A display panel 41, operation buttons 47, and indicator lights 48 are disposed on the front housing 46A. The display panel 41 is housed within the second housing 46 with its display surface 41A facing outwards. The display panel 41 displays predetermined information required for controlling the printing apparatus 1 on its display surface 41A. Examples of display panels 41 include liquid crystal displays. Alternatively, a touch panel-type operation panel may be provided at the front surface side FS of the display surface 41A, which allows input of operation instructions for the printing apparatus 1 corresponding to predetermined operation instruction button images displayed on the display surface 41A.

[0041] A substrate 44 is disposed at the rear surface side RS relative to the display panel 41. The substrate 44 is a circuit board that implements the functions of the display unit 40 based on the control of the control unit. A plurality of through holes 44A are formed on the substrate 44. A metal plate 45 is disposed at the rear surface side RS relative to the substrate 44. The metal plate 45 is a shielding member that protects against electrical noise targeting the substrate 44. A plurality of through holes 45A are formed on the metal plate 45.

[0042] The sound output unit 42 is housed inside the second housing 46 in such a manner that, when viewed from a direction perpendicular to the display surface 41A of the display panel 41, it is located on the rear surface side RS of the display section 40 compared to the display panel 41 and overlaps with the display surface 41A of the display panel 41. In other words, the sound output unit 42 is positioned on the rear surface side RS compared to the display panel 41.

[0043] The buzzer 42A and speaker 42B included in the sound output section 42 are disposed at the rear housing 46B. A small opening is formed on the rear housing 46B, extending from the front surface side FS toward the rear surface 40B, but this is not a limitation, and the small opening may not be formed on the rear housing 46B. The buzzer 42A is disposed corresponding to the through hole 44A formed on the substrate 44 and the through hole 45A formed on the metal plate 45, respectively. Similarly, the speaker 42B is disposed corresponding to the through hole 44A formed on the substrate 44 and the through hole 45A formed on the metal plate 45, respectively.

[0044] The sound output unit 42, including the buzzer 42A and the speaker 42B, outputs predetermined sounds based on the control state of the printing device 1. The output direction E of the predetermined sounds output from the sound output unit 42 is towards the display surface 41A. With this structure, the predetermined sounds output from the buzzer 42A and the speaker 42B are propagated towards the display surface 41A through the air inside the second housing 46, the display panel 41, the front housing 46A, and other media.

[0045] Buzzer 42A outputs sound by vibrating its own diaphragm at a specific frequency. Speaker 42B converts electrical signals that change sound into vibrations in the air to output sound. In this embodiment, the volume of the sound output by buzzer 42A and speaker 42B is different. The volume of the sound output from buzzer 42A is greater than the volume of the sound output from speaker 42B.

[0046] Buzzer 42A informs the user of the control status of printing device 1 by outputting a single tone with a volume higher than that of speaker 42B. On the other hand, speaker 42B informs the user of the control status of printing device 1, which differs from the sound output from buzzer 42A, by outputting at least one melody. In this embodiment, speaker 42B outputs two different volumes of sound, but the output volume could also be only one.

[0047] A sheet component 43 is disposed between the display panel 41 and the buzzer 42A. In this embodiment, the sheet component 43 is disposed on the surface of the buzzer 42A facing the front surface side FS. The sheet component 43 is a porous component. The porous component can be a so-called sponge-like component with irregularly continuous, perforated amorphous pores, or it can be a component with irregularly independent, non-perforated amorphous pores. In addition, the sheet component 43 is not limited to a porous component. The sheet component 43 can be, for example, a strip-shaped soft component without porosity, or a plate-shaped soft component without porosity.

[0048] A loud single tone output from buzzer 42A in the output direction E is diffused by the thin plate member 43. Without the thin plate member 43, the loud single tone output from buzzer 42A is sometimes reflected by the back surface 41B of display panel 41 and returns to the diaphragm of buzzer 42A. This can sometimes disrupt the vibration of the diaphragm of buzzer 42A, causing the sound output from buzzer 42A to become pitch-distorted. In particular, buzzers 42A that output loud single tones are prone to pitch distortion.

[0049] In this embodiment, since the thin sheet member 43 is disposed on the front surface side FS of the buzzer 42A, the sound output from the buzzer 42A can be diffused at a position closest to the diaphragm of the buzzer 42A. This suppresses single tones reflected from the back surface 41B of the display panel 41 and returning to the diaphragm of the buzzer 42A, thus effectively suppressing pitch shifts in the sound output from the buzzer 42A.

[0050] The rear housing 46B has a hinge 46C. The hinge 46C is part of the tilting mechanism and is a rotation axis that allows the display unit 40 to be displaced between a first position P1 and a second position P2. The display unit 40 is connected to the main part of the tilting mechanism (not shown) via the hinge 46C, etc.

[0051] The operation button 47 may be a power button, other function buttons, etc. The operation button 47 may consist of buttons, touch sensors, etc., but is not limited to these. The indicator light 48 may consist of LEDs (Light Emitting Diodes), etc., but is not limited to these. Furthermore, the indicator light 48 can change its illumination state to display the control state of the printing apparatus 1.

[0052] As described above, the printing apparatus 1 according to this embodiment can achieve the following effects. The printing apparatus 1 of this embodiment includes a head 5 for printing on a medium M. The printing apparatus 1 further includes: a first housing 100 having a housing portion 101 on its upper surface 100A and covering the head 5; and a display portion 40 movable between a first position P1 where the rear surface 40B is housed in the housing portion 101 and a second position P2 where the rear surface 40B is exposed from the housing portion 101. The display portion 40 internally includes: a display panel 41 having a display surface 41A facing a side opposite to the direction facing the rear surface 40B; and a sound output portion 42 disposed on the rear surface side RS compared to the display panel 41, and outputting a predetermined sound. The output direction E of the predetermined sound output from the sound output portion 42 is towards the display surface 41A.

[0053] According to this embodiment, the predetermined sound output direction E from the sound output unit 42 is towards the display surface 41A. Therefore, compared to the case where the sound output direction E from the sound output unit 42 is towards the rear surface 40B, the sound that the user can hear is less likely to become quieter. In other words, the difference in volume between the display unit 40 being moved to the first position P1 and the display unit 40 being moved to the second position P2 can be reduced. As a result, regardless of the position of the display unit 40, the user can easily hear the sound, thus eliminating the need for operations such as raising the display unit 40 to expose the rear surface 40B of the display unit 40, thereby suppressing a decrease in usability.

[0054] Furthermore, according to this embodiment, the display unit 40 has a thin sheet member 43 between the display panel 41 and the buzzer 42A. This allows for the suppression of pitch distortion between the display panel 41 and the buzzer 42A.

[0055] Furthermore, according to this embodiment, the sheet component 43 is a porous component, thus effectively suppressing the generation of pitch distortion between the display panel 41 and the buzzer 42A.

[0056] The embodiments have been described in detail above with reference to the accompanying drawings. However, the specific structure is not limited to each embodiment. Modifications, substitutions, deletions, etc., can be made as long as they do not depart from the spirit of the invention. Furthermore, other embodiments as described below are also possible. According to other embodiments, the same effects as the embodiments described above can also be obtained.

[0057] In the above embodiment, the first housing 100 has a receiving portion 101 on its upper surface 100A in the +Z direction, but it is not limited to this. For example, the first housing 100 may also have a receiving portion 101 on a side surface of the first housing 100 that is a surface intersecting the X-axis or a surface intersecting the Y-axis. In this case, the side surface is an example of a "first surface". In addition, when the receiving portion 101 is on a side surface of the first housing 100, the first direction is the direction in which the side surface faces.

[0058] In the above embodiment, the sheet component 43 is disposed between the display panel 41 and the buzzer 42A, but it may also be disposed between the display panel 41 and the speaker 42B.

[0059] In the above embodiments, in order to suppress the generation of pitch distortion, the thin sheet component 43 is disposed between the display panel 41 and the buzzer 42A, but the thin sheet component 43 may not be disposed. For example, in Figure 5 In this method, by outputting a predetermined sound from the buzzer 42A in a direction that intersects the normal to the back surface 41B of the display panel 41 with a vector component in the +Y direction, the generation of sound pitch distortion can also be suppressed. Alternatively, by increasing the distance between the back surface 41B of the display panel 41 and the front-facing side FS of the buzzer 42A, the generation of sound pitch distortion can also be suppressed. As an example, in this case, the distance between the back surface 41B of the display panel 41 and the front-facing side FS of the buzzer 42A is 5.7 mm or more.

[0060] In the above embodiment, the output direction E of the predetermined sound output from the speaker 42B is the same as that of the buzzer 42A, facing the display surface 41A, but it is not limited to this. For example, the output sound direction may differ between the buzzer 42A and the speaker 42B. In this case, the predetermined sound output from the speaker 42B may also be output in the direction facing the rear surface 40B. The reason for this is that the melody output from the speaker 42B is an easily audible sound regardless of the position of the display unit 40. Therefore, it is not necessary to perform operations such as raising the display unit 40 to expose the rear surface 40B of the display unit 40, thereby suppressing the reduction in usability.

[0061] In the above embodiment, a through hole 44A is formed on the substrate 44, but it is not limited to this, and the through hole 44A may not be formed on the substrate 44. In this case, the relationship between the sound reflection, separation distance, and opposing angle related to the display panel 41 and the buzzer 42A is replaced by the relationship between the substrate 44 and the buzzer 42A.

[0062] In the above embodiment, a through hole 45A is formed on the metal plate 45, but this is not a limitation; the through hole 45A may not be formed on the metal plate 45. In this case, the relationship between the display panel 41 and the buzzer 42A is replaced by the relationship between the metal plate 45 and the buzzer 42A.

[0063] In the above embodiment, a substrate 44 and a metal plate 45 are disposed between the display panel 41 and the sound output unit 42, but this is not a limitation. For example, the substrate 44 and the metal plate 45 may be disposed in a location other than between the display panel 41 and the sound output unit 42, or they may be disposed in a location where the substrate 44 and the metal plate 45 do not overlap with the sound output unit 42 when viewed from a direction perpendicular to the display surface 41A on the rear surface side RS.

[0064] In the above embodiment, the thin sheet component 43 is disposed on the front surface side FS of the buzzer 42A, but it is not limited to this. For example, the thin sheet component 43 may also be disposed in any of the display panel 41, the substrate 44, and the metal plate 45 at a position opposite to the buzzer 42A. Thus, the front surface side FS of the buzzer 42A is not blocked by the thin sheet component 43, so most of the sound output from the buzzer 42A can be output in the direction toward the display surface 41A, and the occurrence of sound pitch distortion can be suppressed.
