DETAILED DESCRIPTION

[0031] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. It should be noted that in the description, the description of directions such as front, back, left, right, and top and bottom are the same as the directions relative to the printing device 1 unless otherwise specified. In addition, the reference symbol FR shown in each figure indicates the front of the printing device 1 when the printing device 1 is used, the reference symbol UP indicates the top of the printing device 1, and the reference symbol LH indicates the left of the printing device 1.

[0032] Figure 1 This is a perspective view of the printing device 1 as viewed from the right. Figure 1 In FIG. 1 , the portion of the exterior panel 9 that covers the conveyance path R is indicated by dots.

[0033] The printing device 1 is a so-called line inkjet printer that includes a line-shaped inkjet head and ejects ink from the inkjet head to print characters or images on a printing medium.

[0034] The printing medium used for printing in the printing device 1 is a cut sheet or a continuous sheet cut into a predetermined size. These sheets are formed of paper, synthetic resin, etc. These sheets may be, for example, high-quality paper suitable for inkjet printing and subjected to surface processing to improve ink absorption and fixability.

[0035] Examples of the continuous sheet include roll paper stored in the printing device 1 in a rolled state, and fan protection paper supplied to the printing device 1 in a folded state from the outside of the printing device 1. As the roll paper, in addition to ordinary paper and high-quality paper rolled in a roll, label paper in which labels with fixed sizes with adhesive on the back are arranged on release paper as a backing paper and rolled in a roll can also be used.

[0036] In this embodiment, labels of a predetermined size with adhesive on the back are arranged on a backing paper on which a release paper that can be peeled off from the adhesive is formed in a long strip, and a label paper 100 rolled up is used as a printing medium. The label paper 100 has a plurality of labels arranged at equal intervals in the length direction of the backing paper. The printing device 1 conveys the label paper 100 and prints text or images on the printing surface of each label on the label paper 100. That is, the printing device 1 is a label printer.

[0037] It should be noted that the label paper 100 is as described below. Figure 8 shown.

[0038] Figure 2 It is a front view of the printing device 1 . Figure 3 It is a rear view of the printing device 1. Figure 4 It is a left side view of the printing device. Figure 5 It is a right side view of the printing device. Figure 6 It is a top view of the printing device. Figure 7is a bottom view of the printing device. Figures 2 to 7 In FIG. 1 , the portion of the exterior panel 9 that covers the conveyance path R is indicated by dots.

[0039] like Figures 1 to 7 As shown, the printing device 1 includes a device casing 10 which is a substantially rectangular parallelepiped casing. The device casing 10 is formed by combining a plurality of exterior panels 9 forming the side surfaces, the front surface, the back surface, etc. The device casing 10 is an exterior part forming the outer shell of the printing device 1.

[0040] like Figure 2 , Figure 3 As shown, a step shape is provided on the top surface of the device case 10. In the top surface of the device case 10, the top surface portion located on the left side is located above the top surface portion located on the right side.

[0041] like Figure 1 , Figure 2 As shown in FIG. 1 , a display and operation panel 12 is provided on the front surface of the device housing 10 at the upper half portion near the left. A display 60 that functions as a display unit for displaying predetermined information and operation elements 62 such as operation buttons are arranged on a flat surface portion 61 of the display and operation panel 12. Figure 2 , Figure 3 As shown, the display and operation panel 12 has a flat plate shape with a predetermined thickness dimension. The display and operation panel 12 is arranged so that the longitudinal direction extends in the left-right direction.

[0042] like Figure 1 , Figure 2 , Figure 4 As shown, the display and operation panel 12 is provided on the front surface side of the operation unit facing panel 64 which is a part of the exterior panel 9. Figure 4 As shown, the operation unit facing plate 64 has a concave shape that is recessed from the front surface side of the device housing 10 to the back surface side of the device housing 10. This concave shape is formed along the outer shape of the back surface of the display and operation panel 12. Therefore, the display and operation panel 12 is configured so that the back surface is arranged parallel to the operation unit facing panel 64 and is embedded in the operation unit facing panel 64.

[0043] Thus, in the printing device 1, the portion where the display and operation panel 12 protrudes from the device housing 10 is reduced. Therefore, in the printing device 1, the display and operation panel 12 can be installed while suppressing the increase of the installation space. Furthermore, when the printing device 1 is packaged and transported, for example, the box that accommodates the printing device 1 can be reduced in size. That is, when the printing device 1 is packaged, the increase of packaging materials can be suppressed. Therefore, the printing device 1 can be transported at a low cost, and the transportation efficiency can be improved.

[0044] like Figure 4 , Figure 5 As shown, when the back surface and the operation portion opposing panel 64 are arranged in parallel, the upper end portion of the display and operation panel 12 has a curved shape protruding upward.

[0045] Thus, for example, even when liquid or the like is attached from above in the printing device 1, the liquid can be discharged along the curved surface at the upper end of the display / operation panel 12. Therefore, the attached matter is suppressed from being accumulated in the display / operation panel 12. In addition, in the printing device 1, it is possible to prevent the liquid from entering the electronic substrate, electronic components, and wiring inside the display / operation panel 12.

[0046] At the upper end of the display and operation panel 12, the curved surface is a semicircular shape that is concentric with the rotation axis of the display and operation panel 12. In addition, at the upper end opposite to the curved surface, a curved surface along the curved surface is formed in the operation portion opposing panel 64. Therefore, the upper end of the display and operation panel 12 and the upper end of the operation portion opposing panel 64 are arranged with a predetermined gap therebetween.

[0047] Thus, in the printing device 1 , when the display / operation panel 12 is rotated about the rotation axis, the gap between the upper end of the display / operation panel 12 and the upper end of the operation unit opposing panel 64 is kept constant within the rotational range of the display / operation panel 12 .

[0048] Therefore, when the display and operation panel 12 is rotated, it is possible to suppress foreign matter or the like from being caught in the gap between the upper end of the display and operation panel 12 and the upper end of the operation portion opposing panel 64 .

[0049] The display and operation panel 12 corresponds to the “operation unit”.

[0050] like Figure 1 As shown, a paper cover 16 is provided on the device housing 10 so as to be openable and closable. The paper cover 16 forms a part of the front surface and a part of the top surface of the printing device 1. The paper cover 16 is formed from a position close to the right of the front surface of the device housing 10 to a position close to the front of the top surface of the device housing.

[0051] In the present embodiment, the paper cover 16 forms a part of the top surface of the printing device 1 .

[0052] The paper cover 16 is formed on the top surface of the device housing 10 so as to be openable and closable by rotating around a connecting portion 120 provided substantially at the center in the front-rear direction.

[0053] A storage section 20 for storing label paper 100 is provided inside the paper cover 16. In the printing device 1, by opening the paper cover 16, the label paper 100 rolled up can be loaded into the storage section 20. In the printing device 1, by opening the paper cover 16, the inside of the device housing 10 can be accessed from the outside, and the storage section 20 and various parts related to transportation can be operated.

[0054] In the device housing 10, a printing unit cover 19 is provided on the left side of the paper cover 16. The printing unit cover 19 is formed at a portion close to the front surface of the device housing 10 on the top surface. The printing unit cover 19 is formed to be openable and closable by rotating around a connecting portion 121 provided at the substantially center of the top surface of the device housing 10.

[0055] The printing unit 22 for printing on the label paper 100 is provided below the printing unit cover 19. That is, the printing unit cover 19 covers the printing unit 22 from above.

[0056] like Figure 4 As shown, a slit-shaped paper discharge port 14 extending in the front-rear direction is formed on the left side of the device housing 10 and approximately in the center near the front surface when viewed from the left side. In the printing device 1, the printed label paper 100 is discharged from the paper discharge port 14.

[0057] In the present embodiment, an operation unit, a display unit, or the like is not provided on the side surface where the paper discharge port 14 is formed.

[0058] Figure 8 It is a rear view of the main parts showing each part related to the conveyance path R of the printing device 1.

[0059] like Figure 8 As shown, the printing device 1 includes a storage unit 20 for storing label paper 100 , a printing unit 22 for printing on the label paper 100 , and a conveying unit 24 for conveying the label paper 100 from the storage unit 20 to the printing unit 22 .

[0060] like Figures 1 to 8 As shown, in the printing device 1, the storage unit 20 is provided on the right side, and the printing unit 22 is provided on the left side of the storage unit 20. The conveying unit 24 is provided below the printing unit 22.

[0061] The storage section 20 includes a roller shaft 26 on which the label paper 100 is mounted. The roller shaft 26 is a rod-shaped member rotatably provided in the circumferential direction. The label paper 100 is stored in the storage section 20 by inserting the roller shaft 26 through the center of the roll of the label paper 100 .

[0062] A driving device such as a motor is connected to the roller shaft 26, and the roller shaft 26 may be rotated by the driving of the driving device. In the printing device 1, the label paper 100 rotates when the roller shaft 26 rotates.

[0063] In the printing device 1 , a conveyance path R is formed, which pulls out one end of the label paper 100 attached to the roller 26 and conveys it to the paper discharge port 14 .

[0064] On the conveying path R, a tension rod 28 is installed above the label paper 100 accommodated in the accommodating portion 20. The tension rod 28 has a curved surface in the circumferential direction and is formed in a columnar shape extending in the front-rear direction. The tension rod 28 applies tension to the label paper 100 to prevent it from loosening. One end of the label paper 100 is pulled upward, contacts the tension rod 28, is bent by the tension rod 28, and then extends to the left.

[0065] A paper guide unit 30 is provided on the left side of the tension bar 28. The paper guide unit 30 guides the label paper 100 to the left, and suppresses the oblique movement of the label paper 100 and conveyance deviation of the label paper 100.

[0066] The paper guide unit 30 includes a lower guide member 32 that supports the label paper 100 from below, and a pair of paper pressing members 34 that are located on the upper surface side of the label paper 100 .

[0067] The lower guide member 32 includes a flat surface 33 extending in the left-right direction. The flat surface 33 has a width longer than the width of the label paper 100 along the front-rear direction of the device housing 10. The label paper 100 is placed on the flat surface 33 of the lower guide member 32 and supported.

[0068] The paper pressing member 34 is opposite to the lower guide member 32, is located above the label paper 100, and presses the floating of the label paper 100. The paper pressing members 34 are respectively arranged at respective locations located at both ends of the lower guide member 32 along a direction intersecting the conveying direction F. Each paper pressing member 34 is provided to be rotatable about a rotation axis parallel to the conveying direction F as a rotation center. The paper pressing member 34 can rotate from a position facing the flat surface 33 with a predetermined gap left therebetween to a position separated from the flat surface 33.

[0069] The label paper 100 is placed on the flat surface 33 with the paper pressing members 34 placed at positions separated from the flat surface 33. Then, the paper pressing members 34 are rotated to a position facing the flat surface 33 with a predetermined gap therebetween, and are sandwiched between the lower guide member 32 and the paper pressing member 34.

[0070] The label paper 100 is conveyed in a state where the paper guide unit 30 is sandwiched between the lower guide member 32 and the paper pressing member 34. The paper guide unit 30 functions as a guide for the label paper 100.

[0071] A printing section 22 for printing on the label paper 100 is provided on the left side of the paper guide unit 30. The printing section 22 includes a platen 40 and a print head 42. The print head 42 of this embodiment ejects four colors of ink, namely, C (cyan), M (magenta), Y (yellow), and K (black), to form dots on the printed surface of the label. The print head 42 includes a nozzle section 41 for ejecting K (black) ink, a nozzle section 43 for ejecting C (cyan) ink, a nozzle section 45 for ejecting M (magenta) ink, and a nozzle section 47 for ejecting Y (yellow) ink. In the nozzle sections 41 to 47, a plurality of nozzles for ejecting ink are arranged in a row in the width direction of the label paper 100. The nozzles provided in each of the nozzle sections 41 to 47 are arranged in a direction intersecting the conveying direction F. In this embodiment, the direction in which the nozzles are arranged is a direction orthogonal to the conveying direction F. The direction in which the nozzles are arranged coincides with the width direction of the label paper 100. The print head 42 functions as an image forming section.

[0072] The print head 42 is a line inkjet head that can eject ink without scanning in the width direction of the label paper 100. Therefore, the nozzle array of the nozzle units 41 to 47 is formed to have at least the same width as or wider than the printable range of the label paper 100. In the present embodiment, the printable range corresponds to the printing surface of the label.

[0073] In the present embodiment, an example configuration is given in which the nozzle portions 41 , 43 , 45 , and 47 are arranged in this order along the conveyance direction F of the label paper 100 . However, the arrangement order of the nozzles of each color in the conveyance direction F is arbitrary.

[0074] The platen 40 has a plane arranged parallel to the conveying direction F. The plane is located below the conveying path R and faces the print head 42. The nozzle units 41 to 47 are arranged with a so-called platen gap between them and the platen 40.

[0075] The platen 40 has a flat upper surface that supports the label paper 100 from below. The platen 40 is provided at least over the entire printing range of the printing unit 22. The upper surface of the platen 40 is arranged substantially horizontally when the printing device 1 is installed or in use.

[0076] The conveying unit 24 includes a cylindrical conveying roller 50. The conveying roller 50 is arranged so that its longitudinal direction extends in a direction intersecting the conveying direction F and is rotatable in the circumferential direction. The conveying roller 50 is arranged in the conveying direction F between the left end of the paper guide unit 30 and the right end of the platen 40.

[0077] A driven wheel is provided at one end of the conveying roller 50. A transmission belt 51 is mounted on the driven wheel. The transmission belt 51 is hung on a driving shaft provided in the conveying motor 52. Thus, the conveying roller 50 and the conveying motor 52 are connected via the transmission belt 51.

[0078] The conveying motor 52 is a driving device for driving the conveying roller 50 to rotate. The conveying motor 52 and the driving belt 51 are provided below the platen 40.

[0079] The conveying unit 24 includes a plurality of driven rollers 54. The driven rollers 54 have a cylindrical shape, and the peripheral surface is formed of a flexible material such as a rubber material. A plurality of driven rollers 54 are rotatably arranged along the longitudinal direction of the conveying roller 50. Each driven roller 54 is urged so that the peripheral surface contacts the peripheral surface of the conveying roller 50. Thus, the conveying roller 50 and the driven rollers 54 are arranged in contact with each other with their peripheral surfaces facing each other.

[0080] The transport roller 50 is arranged on the lower guide member 32 side, and the driven roller 54 is arranged on the paper pressing member 34 side.

[0081] The conveying roller 50 may be disposed on the lower guide member 32 side, in other words, on the platen 40 side. In addition, for example, the conveying unit 24 may include a conveying belt that can move on the upper surface of the platen 40 instead of the conveying roller 50 .

[0082] In the conveying unit 24, the conveying motor 52 is driven to rotate the conveying roller 50 via the transmission belt 51, and the driven roller 54 is driven to rotate. As a result, the label paper 100 loaded between the lower guide member 32 and the paper pressing member 34 is clamped between the conveying roller 50 and the driven roller 54, and is conveyed to the printing unit 22 as the conveying roller 50 is driven to rotate.

[0083] The label paper 100 placed on the flat surface 33 and fed from the paper guide unit 30 is inserted and sandwiched between the conveying roller 50 and the driven roller 54. In this state, the conveying roller 50 is rotated, and the label paper 100 is conveyed to the printing unit 22.

[0084] In the printing device 1 , a transport roller pair is formed by the transport roller 50 and the driven roller 54 .

[0085] In the printing device 1 , a label detector 70 is provided in the transport path R. The label detector 70 detects the leading end and the trailing end of the label paper 100 and the leading end and the trailing end of the label.

[0086] The label detector 70 of the present embodiment is arranged on the downstream side of the paper guide unit 30 and the upstream side of the conveying roller 50. The label detector 70 is, for example, an optical transmission type sensor having a light emitting unit 72 on the lower side of the label paper 100 and a light receiving unit 74 on the upper side of the label paper 100 in the conveying path R. The light emitting unit 72 and the light receiving unit 74 are arranged opposite to each other in the vertical direction with a gap therebetween to the extent that the label paper 100 can pass through. That is, the light emitting unit 72 and the light receiving unit 74 are arranged opposite to each other in the thickness direction of the label paper 100. Thus, the light emitting unit 72 and the light receiving unit 74 are arranged at approximately the same position in the left-right direction.

[0087] It should be noted that the label detector 70 may be arranged on the downstream side of the transport roller 50 and the upstream side of the print head 42 .

[0088] For example, the light emitting unit 72 may be disposed on the lower guide member 32 side, and the light receiving unit 74 may be disposed on the paper pressing member 34 side. In this case, the light emitting unit 72 may be disposed on the platen 40 side, and the light receiving unit 74 may be disposed on the print head 42 side.

[0089] In the label detector 70, the light emitting unit 72 and the light receiving unit 74 can be arranged at a position where the light receiving unit 74 can receive the light emitted from the light emitting unit 72 with a predetermined signal strength. In this case, the output value indicating the amount of light received by the light receiving unit 74 is different in the case where there is no label paper 100, the case where there is a backing paper, and the case where there is a label directly below the light receiving unit 74. That is, the signal strengths of the emitted light from the light emitting unit 72, the transmitted light of the backing paper, and the transmitted light of the label are different from each other. Therefore, the label detector 70 can detect the front and rear ends of the label paper 100 and the front and rear ends of the label based on the output value indicating the amount of light received by the light receiving unit 74.

[0090] A cutting unit 110 is arranged on the downstream side in the conveying direction F of the print head 42, in other words, on the left side of the print head 42. The cutting unit 110 includes a fixed knife 112 and a movable knife 114 arranged to sandwich the conveying path R, and the movable knife 114 is connected to a driving device such as a motor that drives the knife via a gear or the like. In the cutting unit 110, when the motor is driven, the movable knife 114 moves to the fixed knife 112 side to cut the label paper 100. The cutting unit 110 can be a unit that cuts a portion of the label paper 100 in the width direction and leaves a residual cut, or a unit that completely cuts the label paper 100. The printing device 1 cuts the label paper 100 printed by the print head 42 into a predetermined length through the cutting unit 110, and discharges it from the paper discharge port 14.

[0091] It should be noted that the cutting unit 110 is formed separately from the printing device 1 , and may be detachably provided on the left side of the printing device 1 , for example.

[0092] The printing device 1 includes a control substrate 18 for controlling various parts of the printing device 1. The control substrate 18 includes a CPU, a ROM, a RAM, etc. as a calculation execution unit. The ROM of the control substrate 18 stores firmware executable by the CPU, data related to the firmware, etc. in a non-volatile manner. In addition, data related to the firmware executed by the CPU, etc. are temporarily stored in the RAM. The control substrate 18 may also include other peripheral circuits, etc. The control substrate 18 may also include a storage unit that can store various programs and data in a non-volatile manner, such as control programs and data related to these control programs.

[0093] The control board 18 is formed so as to be able to detect operations on the printing device 1 and the conveyance amount of the label paper 100 .

[0094] The control board 18 is formed so as to be able to control the driving device provided in the printing device 1 , such as the transport motor 52 .

[0095] The control board 18 supplies voltage to a pump that supplies ink from an ink tank and piezoelectric elements provided in the nozzles 41 to 47 of the print head 42 in the print head 42 to operate them. In this way, ink droplets are ejected from each nozzle of the nozzles 41 to 47 in the printing device 1 to form dots.

[0096] like Figure 8 As shown, a frame 4 is housed inside the device housing 10. The frame 4 is a skeleton member for mounting various mechanism parts of the printing device 1, such as the storage part 20, the printing part 22, the conveying part 24, and the control substrate 18, and supporting the mechanism parts. The printing device 1 is formed by the frame 4 on which the various mechanism parts are mounted being covered by the exterior panels 9.

[0097] In this embodiment, the frame 4 is formed of a metal member. Thus, the frame 4 can ensure electrical conduction. Therefore, the printing device 1 can achieve improved resistance to noise caused by static electricity, etc. Furthermore, the printing device 1 can reduce the influence of external electromagnetic waves from the printing device 1 and suppress the release of radiated electromagnetic waves from the printing device 1.

[0098] It should be noted that the frame 4 is not limited to a metal member, and may be formed of other members such as a resin material.

[0099] like Figures 1 to 8As shown, in the exterior panel 9, the periphery of the paper discharge port 14, the printing unit cover 19, the upper part of the paper cover 16, the display and operation panel 12, and the operation unit opposing panel 64 located on the back side of the display and operation panel 12 are given a color different from other parts. In this way, the part given a color different from other parts corresponds to the part covering the conveying path R. As a result, in the printing device 1, in the exterior panel 9, a contrast is generated between the part covering the conveying path R and the other parts. Therefore, in the printing device 1, the user can easily understand the position of the conveying path R from the appearance.

[0100] In the printing device 1 of the present embodiment, the portion covering the transport path R is painted with a black-based color, and the other portions are painted with a white-based color.

[0101] It should be noted that, in the printing device 1, a certain degree of color difference may be present between the portion covering the conveying path R and other portions. For example, the portion covering the conveying path R may be set to a white color, and other portions may be set to a black color. In addition, for example, in the printing device 1, one of the portion covering the conveying path R and other portions may be set to a color, and the other may be set to a colorless color.

[0102] Fig. 9 , Fig.10 It is a perspective view of the display and operation panel 12 .

[0103] like Fig. 9 , Fig.10 As shown, the display and operation panel 12 is provided so as to be rotatable with the long side located at the upper end when viewed from the front as a rotation axis.

[0104] The operation unit facing panel 64 of the display and operation panel 12 is located on the back side of the display and operation panel 12. The display and operation panel 12 can be rotated steplessly from a state where the plane portion 61 is arranged parallel to the front surface of the printing device 1 to a state where the plane portion 61 is arranged approximately perpendicular to the front surface of the printing device 1, with the back side abutting against the surface of the operation unit facing panel 64. That is, the display and operation panel 12 can be arranged so that the plane portion 61 is at 0 degrees to approximately 90 degrees with respect to the front surface of the printing device 1.

[0105] Thus, in the printing device 1 , for example, even when the user operates from the left side, the display and operation panel 12 can be operated and visually confirmed by arranging the flat surface 61 at approximately 90 degrees relative to the front surface of the printing device 1 .

[0106] In the printing device 1 , the flat surface portion 61 is arranged at substantially 0 degrees with respect to the front surface of the printing device 1 , so that the operator can easily check the operation panel even when the operator is seated.

[0107] Furthermore, when the plane portion 61 is substantially at 0 degrees relative to the front surface of the printing device 1, the space required for arranging the printing device 1 can be reduced in the printing device 1. Thus, for example, when the printing device 1 is packed and transported, the plane portion 61 is packed in a state substantially at 0 degrees relative to the front surface of the printing device 1, and the printing device 1 can suppress the increase of packing materials. Therefore, the printing device 1 can be transported at low cost, and the transport efficiency can be improved.

[0108] In the following description, the plane portion 61 is set to be at approximately 0 degrees relative to the front surface of the printing device 1, and the state of the display and operation panel 12 is set to be in a 0-degree posture, and the plane portion 61 is set to be at approximately 90 degrees relative to the front surface of the printing device 1, and the state of the display and operation panel 12 is set to be in a 90-degree posture.

[0109] Furthermore, the display and operation panel 12 can maintain a state formed at any angle within the rotatable range.

[0110] Fig.11 yes Fig. 9 Cross-sectional view at plane XI. Fig.12 yes Fig.10 Cross-sectional view at plane XII.

[0111] like Fig.11 , Fig.12 As shown, the display and operation panel 12 includes a front surface panel 66 forming the plane portion 61 and a back surface panel 68 forming the back surface, which are combined to form the frame of the display and operation panel 12. The back surface panel 68 is provided with a back surface concave portion 67 that is concave toward the front surface panel 66 side.

[0112] The front panel 66 and the back panel 68 are arranged with a gap V1 therebetween at a location corresponding to the long side that serves as the rotation axis of the display / operation panel 12 .

[0113] Here, if Fig.11 , 12 As shown, the operation portion opposing panel 64 is formed by an upper opposing panel 76 and a lower opposing panel 78 located below the upper opposing panel 76. A gap V2 is provided between the lower end of the upper opposing panel 76 and the upper end of the lower opposing panel 78.

[0114] Fig.13 It is a perspective view showing the display and operation panel 12 and the operation unit opposing panel 64 .

[0115] like Fig.13 As shown in FIG. 1 , a bulging portion 79 bulging from the inside to the outside of the device housing 10 is provided on the lower opposing panel 78. Fig.11 , Fig.12As shown, a bulging space S is provided inside the bulging portion 79. The bulging space S accommodates wiring 150 extending from the printing unit 22, the conveying unit 24, the control substrate 18, and the like.

[0116] The bulging portion 79 has a shape that is entirely fitted into the inside of the back recess 67. Therefore, in the printing device 1, the bulging portion 79 can be provided while suppressing the display / operation panel 12 from protruding outward from the device housing 10.

[0117] like Fig.11 , Fig.12 As shown, the gap V1 and the gap V2 are penetrated with the wiring 150 extending from the inside of the bulged space S. The wiring 150 is always arranged inside the gap V1 and the gap V2 within the range in which the display / operation panel 12 can rotate.

[0118] Therefore, the printing device 1 has a function of rotating the display and operation panel 12 , and can connect the components disposed inside the device housing 10 and the internal mechanism of the display and operation panel 12 .

[0119] In the printing device 1, the wiring 150 is not exposed to the outside of the printing device 1, and is contained in the gaps V1 and V2, thereby suppressing the electrostatic noise outside the printing device 1 from being discharged to the electronic circuit portion inside the printing device 1. Therefore, in the printing device 1, malfunctions of various electrical components provided in the printing device 1 due to the noise are suppressed.

[0120] Furthermore, in the printing device 1 , disconnection of the wiring 150 due to erroneous operation etc. can be prevented, and the function can be ensured while hiding the gaps V1 and V2 . Therefore, the printing device 1 can ensure the appearance and design, and improve the degree of freedom in design.

[0121] like Fig.13 As shown, the back panel 68 is provided with an operation slit 63, which is formed by cutting downward from the long side located at the top when the display and operation panel 12 is in a 0-degree posture. The operation slit 63 is provided on the back panel 68 at two ends in the left and right directions.

[0122] The rear panel 68 is provided with a flange 65. The flange 65 has a flange shape rising from the rear panel 68. The flange 65 is provided so as to sandwich the operation portion slit 63 from the left and right directions. The flange 65 has a fan-shaped flange shape centered on the rotation axis of the display and operation panel 12 when viewed from the left and right directions.

[0123] Thus, in the printing device 1, when the display and operation panel 12 is rotated by providing the flange 65, foreign matter is kept away from the portion close to the rotation axis. Thus, in the printing device 1, foreign matter is prevented from being caught between the display and operation panel 12 and the device housing 10.

[0124] The operation unit opposing panel 64 is provided with a plurality of panel slits 69. When the display / operation panel 12 is in a 0 degree posture, the panel slits 69 are provided at positions overlapping the operation unit slits 63 when viewed from the front. The panel slits 69 are formed by cutting downward from the long side located at the upper portion.

[0125] Fig.14 1 is a perspective view of the display and operation panel 12. Fig.14 In the figure, the front surface panel 66 is omitted.

[0126] like Fig.14 As shown, an operation substrate 80 is housed inside the display and operation panel 12. The operation substrate 80 is mounted with a display 60 and an operation element 62. A wiring 150 is connected to the operation substrate 80. The operation substrate 80 is provided with a CPU, a ROM, a RAM, etc. as a calculation execution unit, similarly to the control substrate 18. The ROM of the operation substrate 80 stores firmware that can be executed by the CPU, data related to the firmware, etc. in a non-volatile manner. In addition, data related to the firmware executed by the CPU, etc. are temporarily stored in the RAM. The operation substrate 80 may also have other peripheral circuits, etc. The operation substrate 80 may also have a storage unit for various programs and data such as control programs and data that can be non-volatilely stored.

[0127] The operation substrate 80 is formed so as to operate the light emitting unit 72 and the light receiving unit 74 and to be able to obtain the detection value of the tag detector 70. The tag detector 70 and the operation substrate 80 function together as a detection means.

[0128] A substrate holding portion 82 for holding an operation substrate 80 is accommodated inside the display and operation panel 12. The substrate holding portion 82 is formed in a substantially box shape with the plane opposite to the plane portion 61 omitted. The operation substrate 80 is fixed to the substrate holding portion 82, for example, by screw members, while being accommodated inside the substrate holding portion 82.

[0129] Fig.15 , Fig.16 It is a perspective view of the substrate holding portion 82 and the mounting portion 90 .

[0130] The substrate holding portion 82 is provided with a plate-shaped rising portion 84 surrounding the circumference of the operation substrate 80. The rising portion 84 faces each side of the operation substrate 80 and forms a flat surface rising in the thickness direction of the operation substrate 80.

[0131] like Fig.15 , Fig.16 As shown, the substrate holding portion 82 is provided with a slit 83 formed by cutting downward from the upper long side when the display and operation panel 12 is in the 0 degree posture. The slit 83 is provided in the left-right direction inside the left-right rising portion 84 of the operation substrate 80 when viewed from the front.

[0132] like Fig.14 , Fig.15 , Fig.16 As shown, the display and operation panel 12 is mounted on the frame 4 via a mounting portion 90 .

[0133] The mounting portion 90 is a component mounted on the frame 4 at a location located on the front surface side of the printing device 1. The mounting portion 90 is formed into a long strip extending in the left-right direction. First arm portions 92 are provided at both ends in the longitudinal direction of the mounting portion 90. The first arm portion 92 has a flat plate shape extending from the inner side to the outer side of the device housing 10. The first arm portion 92 is arranged on the outer side of the upright portion 84 located in the left-right direction of the operating substrate 80 in the front view in the left-right direction. The first arm portion 92 is provided so that the plane of the first arm portion 92 is opposite to the plane of the upright portion 84 located in the left-right direction of the operating substrate 80.

[0134] Second arm portions 94 are provided at both ends in the longitudinal direction of the mounting portion 90. The second arm portion 94 has a flat plate shape extending from the inner side to the outer side of the device housing 10, similarly to the first arm portion 92. The second arm portion 94 is arranged outside the upright portion 84 located in the left-right direction of the operating substrate 80 in a front view in the left-right direction. The first arm portion 92 is provided so that the plane of the first arm portion 92 is opposite to the plane of the upright portion 84 located in the left-right direction of the operating substrate 80.

[0135] The first arm portion 92 and the second arm portion 94 extend from the inside of the device housing 10 to the outside through the panel slit 69 , and are inserted through the operation portion slit 63 to be disposed inside the display and operation panel 12 .

[0136] The display and operation panel 12 is rotatably mounted on the printing device 1 via hinges 105. The hinges 105 are formed by coupling the substrate holding portion 82 and the mounting portion 90. The hinges 105 are provided at both ends of the display and operation panel 12.

[0137] In the following description, the hinge portion 105 located at the left end of the display and operation panel 12 is described. The hinge portion 105 located at the right end of the display and operation panel 12 has a substantially similar structure symmetrical to the hinge portion 105 located at the left end. It should be noted that the hinge portion 105 may be provided only at one of the two ends of the display and operation panel 12.

[0138] Fig.17 yes Fig.16 The plane XVII is a plane that is perpendicular to the front-rear direction and passes through the central axis of the rod-shaped portion 101 of the hexagonal bolt 102 in the entire length direction of the rod-shaped portion 101.

[0139] like Fig.17 As shown, in each of the upright portions 84 located in the left-right direction of the operation substrate 80 , a first insertion hole 85 penetrating in the left-right direction is provided at a position close to the long side located at the upper end when the display / operation panel 12 is in the 0 degree posture.

[0140] A second insertion hole 93 penetrating in the left-right direction is provided at the front end portion of the first arm portion 92 .

[0141] Similarly, a third insertion hole 91 penetrating in the left-right direction is provided at the front end of the second arm portion 94. The upper end of the second arm portion 94 is bent toward the first arm portion 92. Thus, in the display and operation panel 12, the hinge portion 105 can be formed smaller.

[0142] The hexagonal bolt 102 is inserted through the first insertion hole 85, the second insertion hole 93, and the third insertion hole 91. The hexagonal bolt 102 includes a rod-shaped portion 101 having a thread groove and a head portion 103 corresponding to a thread head. In this embodiment, the head portion 103 has a hexagonal shape in a plan view.

[0143] The head portion 103 is arranged outside the plane located on the opposite side of the substrate holding portion 82 in the first arm portion 92 .

[0144] The rising portion 84 included in the substrate holding portion 82 and the first arm portion 92 provided in the mounting portion 90 are connected to each other by a hexagonal bolt 102 and are axially supported by each other.

[0145] The washer 104 is inserted into the hexagonal bolt 102. The washer 104 is a cylindrical member having a predetermined length dimension and capable of being inserted through the hexagonal bolt 102. The spacer 104 is arranged between the first arm portion 92 and the rising portion 84. Thus, the first arm portion 92 and the rising portion 84 are arranged at a predetermined interval in the left-right direction.

[0146] The fitting component 106 passes through the hexagonal bolt 102. The fitting component 106 is a component formed in a plate shape. The fitting component 106 is provided with a threaded hole 107 that penetrates along the plate thickness direction of the fitting component 106. The threaded hole 107 is provided with a thread groove. The fitting component 106 is threadedly engaged with the hexagonal bolt 102 by passing the hexagonal bolt 102 through and fitting it in the threaded hole 107. Thus, the substrate holding portion 82 and the mounting portion 90 are fastened to each other.

[0147] The fitting member 106 is arranged between the rising portion 84 and the second arm portion 94 .

[0148] The washer 111 and the disc spring 113 are passed through the hexagonal bolt 102 . The washer 111 and the disc spring 113 are arranged between the rising portion 84 and the fitting member 106 .

[0149] When the hexagonal bolt 102 is screwed into the hinge portion 105, the fitting member 106 moves in the left-right direction so as to approach the head 103. In this case, the washer 111 and the disc spring 113 are sandwiched between the rising portion 84 and the fitting member 106. The washer 111 and the disc spring 113 are pushed toward the rising portion 84 and the fitting member 106 by the urging force and restoring force of the disc spring 113.

[0150] As a result, sliding friction occurs at the contact portions between the washer 111 and the disc spring 113 and the rising portion 84 and the fitting member 106. Therefore, the display and operation panel 12 can maintain a state of forming an arbitrary angle relative to the device housing 10 within the rotatable range due to the sliding friction.

[0151] Thus, in the display and operation panel 12 of the present embodiment, the operation load of the hinge portion 105 can be adjusted by the screw tightening torque of the hexagonal bolt 102. Therefore, in the display and operation panel 12, a high torque can be generated in the hinge portion 105.

[0152] Furthermore, even when the hexagonal bolts 102 are worn, the display and operation panel 12 can be easily disassembled and replaced.

[0153] Furthermore, the washer 111 , the disc spring 113 , the rising portion 84 , and the fitting member 106 can be formed of metal. By forming these members of metal, the occurrence of creep or the like that causes a decrease in sliding friction in the hinge portion 105 can be suppressed.

[0154] It should be noted that the washer 111 may be omitted. In addition, for example, the hinge portion 105 is not limited to the disc spring 113, and any member may be used as long as it is a force-applying member such as a coil spring that can apply force in the length direction of the hexagonal bolt 102. In addition, for example, the hinge portion 105 is not limited to the force-applying member, and other members such as a gasket that are pressed against the rising portion 84 and the fitting member 106 to generate sliding friction may be used.

[0155] The washer 111 and the disc spring 113 correspond to a "crimping portion".

[0156] like Fig.15 , Fig.16As shown in FIG. 1 , a rotation inhibiting portion 117 is provided on the outside of the plane located on the opposite side of the substrate holding portion 82 in the first arm portion 92. The rotation inhibiting portion 117 is a member formed in a plate shape. The rotation inhibiting portion 117 is provided with a long hole 115 penetrating in the plate thickness direction of the rotation inhibiting portion 117. The rotation inhibiting portion 117 is fixed to the first arm portion 92 by a screw 116 inserted through the long hole 115.

[0157] like Fig.15 , Fig.16 , Fig.17 As shown, the rotation restraining portion 117 is provided with a fitting hole 119 penetrating in the plate thickness direction of the rotation restraining portion 117. The fitting hole 119 is formed in a polygonal star shape in a plan view of the rotation restraining portion 117. In the present embodiment, the fitting hole 119 is formed in a dodecagonal shape.

[0158] The head 103 is inserted through the fitting hole 119. Thus, in the printing device 1, loosening of the hexagonal bolt 102 is suppressed.

[0159] Furthermore, the fitting hole 119 has more corners than the head 103. Furthermore, the rotation restraining portion 117 is fixed to the first arm portion 92 via the long hole 115. Therefore, in the printing device 1, the rotation restraining portion 117 can be arranged at a position where the head 103 can be inserted into the fitting hole 119 according to the arrangement of the head 103.

[0160] Thus, by providing the rotation suppressing portion 117, loosening of the hexagonal bolt 102 is suppressed in the display and operation panel 12. Therefore, in the printing device 1, the reduction in the operation load of the display and operation panel 12 caused by loosening of the hexagonal bolt 102 can be suppressed.

[0161] As described above, in this embodiment, the rotation inhibiting portion 117 is provided with the fitting hole 119 of the twelve-sided shape relative to the hexagonal bolt 102. Thus, the rotation inhibiting portion 117 can be aligned with the hexagonal bolt 102 in 30-degree increments. Therefore, in the printing device 1, the length dimension of the arc-shaped long hole 115 can be shortened, and the hinge portion 105 can be formed smaller.

[0162] In the printing device of the present embodiment, the hexagonal bolt 102 is used, and the fitting hole 119 is formed with a twelve-sided shape which is an example of a polygonal star shape. However, the present invention is not limited to this, and a combination of other shapes may be used.

[0163] Here, the reinforcement structure of the hinge portion 105 will be described.

[0164] like Fig.18As shown, in each of the upright portions 84 located in the left-right direction, a cutout portion 87 is provided at the end portion overlapping the first insertion hole 85 in a plan view of the display and operation panel 12. By providing the cutout portion 87, an edge portion 89 of the cutout portion 87 is provided in the upright portion 84. The edge portion 89 extends in the plate thickness direction of the operation substrate 80.

[0165] Fig.18 FIG. 1 is a top view of the hinge portion 105 when the display and operation panel 12 is in a 0-degree posture. Fig.18 In the figure, the fitting component 106 is omitted.

[0166] like Fig.16 As shown in FIG. 1 , an engaging recessed portion 95 formed by cutting downward is provided in the first arm portion 92 at a position overlapping with the second insertion hole 93 in a plan view.

[0167] like Fig.18 As shown, an extension portion 98 extending toward the cutout portion 87 is provided at the tip of the first arm portion 92. Protrusions 99 are provided on the extension portion 98 at positions overlapping the upright portions 84 located in the left and right directions in a plan view. The protrusion 99 protrudes forward from the extension portion 98 by a predetermined length.

[0168] The second arm portion 94 is provided with a plurality of engagement recesses 97 formed by cutting out downward at positions overlapping the third insertion holes 91 in a plan view.

[0169] Fig.19 FIG. 1 is a top view of the hinge portion 105 when the display and operation panel 12 is in a 0-degree posture. Fig.19 In the figure, the fitting part 106 is not omitted.

[0170] The engaging member 106 is provided with a locking piece 130. Fig.17 As shown, the engaging piece 130 is formed integrally with the engaging member 106. Fig.19 As shown in FIG. 1 , the engaging piece 130 is arranged at a position overlapping with the upright portion 84 located in the left-right direction in a plan view, and is arranged at a position substantially the same as the upper end of the first arm portion 92 and the second arm portion 94. The engaging piece 130 includes a plurality of engaging pieces 131. The engaging pieces 131 are engaged with the engaging recess 95, the engaging recess 97 and the front end of the second arm portion 94, respectively.

[0171] When a load is applied to the display / operation panel 12 so that the flat surface 61 is at an angle of 90 degrees or more to the front surface of the printing device 1, the edge 89 contacts the engagement piece 130 and the protrusion 99. As described above, the engagement piece 130 engages with the first arm 92 and the second arm 94.

[0172] Thus, the load is distributedly transmitted to the mounting portion 90 via the edge portion 89 and the engaging piece portion 130. Therefore, even when a force is applied to the display / operation panel 12 to rotate it outside the rotation range, damage to the hinge portion 105 can be suppressed.

[0173] The engaging piece 130 corresponds to a “contact portion”.

[0174] The above embodiment is merely a specific example to which the present invention is applied. The present invention is not limited to the configuration of the above embodiment, and can be implemented in various forms within the scope of the gist of the invention.

[0175] Fig. 20 It is a front view of a printing device 1 according to a modification. Fig.21 It is a rear view of the printing device 1 according to the modification. Fig. 22 1 is a right side view of the printing device 1 according to the modified example. Figure 4 , Figure 6 , Figure 7 Same, so omitted.

[0176] like Figure 20 to Figure 22 As shown, in the printing device 1 , the step shape provided on the top surface of the device housing 10 may be made smaller.

[0177] In the above embodiment, the fitting member 106 is provided in the printing device 1. However, the present invention is not limited thereto, and a nut may be provided in the printing device 1 instead of the fitting member 106. In this case, the nut may be arranged at a position closer to the operation substrate 80 than the second arm portion 94.

[0178] In addition, for example, the third insertion hole 91 may be a screw hole. In this case, the fitting member 106 can be omitted.

[0179] In addition, for example, the second arm portion 94 may be omitted.

[0180] In the above-described embodiment, the mounting portion 90 is provided on the frame 4 . However, the present invention is not limited thereto, and the mounting portion 90 may be provided on the exterior panel 9 .

[0181] In addition, for example, the second arm portion 94 may be omitted.

[0182] In addition, for example, other devices such as a peeling machine that peels the label from the backing paper and the cutting unit 110 may be provided on the left side of the printing device 1 .

[0183] In the above-mentioned embodiment, a label printer is shown as an example of the printing device 1. However, the printing device 1 is not limited to a label printer. The printing device 1 can be any device as long as it has a conveying device for conveying a printing medium and a printing unit 22 for printing on the printing medium. For example, the printing device 1 may be an extrusion printer, a printing and dyeing machine for printing and dyeing, etc.

[0184] In the above-mentioned embodiment, a line head type is exemplified as the print head 42, but the print head 42 is not limited thereto and may be a serial head type. In addition, the printing method of the print head 42 is not limited to the inkjet type.

[0185] The horizontal and vertical directions and various shapes in the above-mentioned embodiments include so-called equivalent ranges that have the same effects as those in these directions and shapes unless otherwise specified.
