[0019] Figure 1 It is a perspective view obtained by observing the printing device 1 from the right side. In Figure 1 the part of the exterior panel 9 covering the conveying path R is shown in the form of marked points.

[0020] The printing device 1 is a so-called line inkjet printer, which has a line-shaped inkjet head and ejects ink from the inkjet head to print characters and images on a printing medium. The printing device 1 is an example of an electronic device.

[0021] In the printing device 1, the printing medium for printing is a cut sheet or a continuous sheet that is cut into a predetermined size. These sheets are formed of paper, synthetic resin, etc. These sheets can also be, for example, fine paper suitable for inkjet printing, and the fine paper has been subjected to surface treatment to improve the ink absorption ability and fixing property.

[0022] Regarding the continuous sheet, for example, there can be mentioned a roll paper stored in the printing device 1 in a state of being wound into a drum shape, and a fan-fold paper supplied to the printing device 1 from the outside of the printing device 1 in a folded state. In addition to ordinary paper and fine paper wound into a drum shape, label paper in which labels of a fixed size with an adhesive on the back are arranged on a release paper as a backing paper and wound into a drum shape can also be used as the roll paper.

[0023] In the present embodiment, label paper 100 in which labels of a predetermined size with an adhesive on the back are arranged on a backing paper and wound into a drum shape is used as the printing medium. The backing paper is formed into a long strip by a release paper that can be peeled off from the adhesive. A plurality of labels of the label paper 100 are arranged at equal intervals in the longitudinal direction of the backing paper. The printing device 1 conveys the label paper 100 and prints characters and images on the printing surfaces of the respective labels on the label paper 100. That is, the printing device 1 is a label printer.

[0024] It should be noted that the label paper 100 is as shown in Figure 3 described later.

[0025] Figure 2 It is a perspective view obtained by observing the printing device 1 from the back side.

[0026] As Figure 1 、 Figure 2 shown, the printing apparatus 1 includes a device housing 10, and the device housing 10 is a substantially rectangular parallelepiped-shaped frame. The device housing 10 is formed by combining a plurality of exterior panels 9 that form the sides, front surface, back surface, etc.

[0027] In the present embodiment, all of the exterior panels 9 are formed of a metal material. It should be noted that this is not limiting, and the exterior panels 9 may also be formed of a resin material. Additionally, for example, the exterior panels 9 may also be formed by a combination of a metal material and a resin material.

[0028] The device housing 10 includes a front surface panel 11, a left top surface panel 13, a right top surface panel 15, a left side surface panel 17, a paper discharge port panel 3, a right side surface panel 5, a back surface panel 6, and a bottom surface panel 7 as the exterior panels 9.

[0029] As Figure 1 shown, the front surface panel 11 forms the lower left part in the front surface of the device housing 10.

[0030] The right side surface panel 5 forms the right side surface of the device housing 10.

[0031] The left top surface panel 13 forms the left back side in the top surface of the device housing 10.

[0032] The right top surface panel 15 forms the right back side in the top surface of the device housing 10.

[0033] A stepped shape is provided on the top surface of the device housing 10. In the top surface of the device housing 10, the top surface portion on the left side is located higher than the top surface portion on the right side. Therefore, the left top surface panel 13 is located above the right top surface panel 15.

[0034] As Figure 2 shown, the left side surface panel 17 forms the left side surface of the device housing 10 except for the periphery of the corner formed by the front surface and the top surface in the left side surface of the device housing 10. The paper discharge port panel 3 is a rectangular panel in the left side surface located at this corner.

[0035] The back surface panel 6 forms the entire back surface of the device housing 10. The bottom surface panel 7 forms the entire bottom surface of the device housing 10.

[0036] In the front surface of the apparatus housing 10, the display / operation panel 12 is provided at a position in the upper half part on the left side. A display 60 that functions as a display unit for displaying predetermined information and operation members 62 such as operation buttons are arranged on the flat surface portion 61 of the display / operation panel 12. The display / operation panel 12 has a flat plate shape with a predetermined thickness dimension. The display / operation panel 12 is arranged such that the long side direction extends in the left-right direction.

[0037] As Figure 1 shown, a paper cover 16 is provided on the apparatus 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 apparatus 1. The paper cover 16 is formed to extend from a position on the right side of the front surface of the apparatus housing 10 to a position in front of the top surface of the apparatus housing 10.

[0038] In the present embodiment, the paper cover 16 forms a part of the top surface of the printing apparatus 1.

[0039] The paper cover 16 rotates about a connecting portion 120 provided substantially at the center in the front-rear direction on the top surface of the apparatus housing 10 and is formed to be openable and closable.

[0040] A storage portion 20 for storing the label paper 100 is provided inside the paper cover 16. In the printing apparatus 1, by opening the paper cover 16, the label paper 100 wound in a roll shape can be loaded into the storage portion 20. In the printing apparatus 1, by opening the paper cover 16, the inside can be accessed from the outside of the apparatus housing 10, and operations of each part related to the storage portion 20 and conveyance can be performed.

[0041] In the apparatus housing 10, a printing unit cover 19 is provided on the left side of the paper cover 16. The printing unit cover 19 forms a portion close to the front surface of the apparatus housing 10 in the top surface portion. The printing unit cover 19 rotates about a connecting portion 121 provided substantially at the center of the top surface of the apparatus housing 10 and is formed to be openable and closable.

[0042] A 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.

[0043] As Figure 2 shown, in the left side surface of the apparatus housing 10, when viewed from this left side surface, a slit-shaped paper discharge port 14 extending in the front-rear direction is formed substantially at the center in the vicinity of the front surface. In the printing apparatus 1, the printed label paper 100 is discharged from the paper discharge port 14. The paper discharge port 14 is provided in a paper discharge port panel 3.

[0044] In the present embodiment, no operation unit, display unit, etc. are provided on the side surface where the paper discharge port 14 is formed.

[0045] Figure 3 This is a rear view of the main parts of each part related to the conveyance path R of the printing apparatus 1.

[0046] As Figure 3 shown, the printing apparatus 1 includes a storage unit 20 for storing the label paper 100, a printing unit 22 for printing on the label paper 100, and a conveyance unit 24 for conveying the label paper 100 from the storage unit 20 to the printing unit 22.

[0047] As Figure 3 shown, in the printing apparatus 1, the storage unit 20 is provided on the right side, the printing unit 22 is provided on the left side of the storage unit 20. The conveyance unit 24 is provided below the printing unit 22.

[0048] The storage unit 20 includes a drum shaft 26 for mounting the label paper 100. The drum shaft 26 is a rod-shaped member provided so as to be rotatable in the circumferential direction. The label paper 100 is stored in the storage unit 20 by passing the drum shaft 26 through the center of the drum of the label paper 100.

[0049] A driving device such as a motor is connected to the drum shaft 26 and can also rotate along with the driving of the driving device. In the printing apparatus 1, when the drum shaft 26 rotates, the label paper 100 rotates.

[0050] The conveyance path R is formed in the printing apparatus 1. In the conveyance path R, one end of the label paper 100 mounted on the drum shaft 26 is drawn out and conveyed to the paper discharge port 14.

[0051] In the conveyance path R, a tension rod 28 is installed above the label paper 100 housed in the storage unit 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 slack. One end of the label paper 100 is drawn upward, contacts the tension rod 28, and after bending through the tension rod 28, extends toward the left.

[0052] A paper guiding unit 30 is provided on the left side of the tension rod 28. The paper guiding unit 30 guides the label paper 100 to the left while suppressing the skewed forward movement and conveyance deviation of the label paper 100.

[0053] The paper guiding unit 30 includes a lower guiding member 32 for supporting the label paper 100 from below and a pair of paper pressing members 34 located on the upper surface side of the label paper 100.

[0054] The lower guide member 32 includes a flat surface 33 extending in the left-right direction. The flat surface 33 extends along the front-rear direction of the device housing 10 and has a width dimension longer than the width dimension of the label paper 100. The label paper 100 is supported by the flat surface 33 of the lower guide member 32 while being placed thereon.

[0055] The paper pressing member 34 is located above the label paper 100 in a manner opposite to the lower guide member 32, and presses the warping of the label paper 100. The paper pressing members 34 are arranged at respective locations 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 opposite to the flat surface 33 with a predetermined gap therebetween to a position separated from the flat surface 33.

[0056] The label paper 100 is placed on the flat surface 33 with the paper pressing members 34 respectively placed at positions separated from the flat surface 33. Then, the label paper 100 is sandwiched between the lower guide member 32 and the paper pressing member 34 by rotating the paper pressing member 34 to face the flat surface 33 with a predetermined gap.

[0057] The label paper 100 is conveyed in a state of being sandwiched between the lower guide member 32 and the paper pressing member 34 in the paper guide unit 30 . The paper guide unit 30 functions as a guide for the label paper 100 .

[0058] The 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 printing head 42. The printing 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 printing surface of the label. The printing 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 printing head 42 functions as an image forming section.

[0059] The print head 42 is a line inkjet head capable of ejecting ink in the width direction of the label paper 100 without scanning. Therefore, the nozzle rows of the nozzle sections 41 to 47 are formed to have a width that is at least the same 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.

[0060] In the present embodiment, a configuration example is given in which the nozzle sections 41, 43, 45, and 47 are arranged in this order along the conveyance direction F of the label paper 100, but the arrangement order of the nozzles of various colors in the conveyance direction F is arbitrary.

[0061] The platen 40 has a plane arranged parallel to the conveyance direction F. This plane is located below the conveyance path R and faces the print head 42. The nozzle sections 41 to 47 are arranged at an interval that is a so-called paper pressing distance from the platen 40.

[0062] The platen 40 has a flat upper surface that supports the label paper 100 from below. The platen 40 is provided at least across the entire printing range of the printing unit 22. The upper surface of the platen 40 is arranged to be substantially horizontal in the set state and the use state of the printing apparatus 1.

[0063] The conveyance unit 24 includes a cylindrical conveyance roller 50. The conveyance roller 50 is arranged such that its long side direction extends along a direction crossing the conveyance direction F and is provided to be rotatable in the circumferential direction. The conveyance roller 50 is arranged between the left end of the paper guide unit 30 and the right end of the platen 40 in the conveyance direction F.

[0064] A driven wheel is provided at one end of the conveyance roller 50. A transmission belt 51 is hung on the driven wheel. This transmission belt 51 is hung on the drive shaft of the conveyance motor 52. Thus, the conveyance roller 50 and the conveyance motor 52 are connected by the transmission belt 51.

[0065] The conveyance motor 52 is a driving device that rotationally drives the conveyance roller 50. The conveyance motor 52 and the transmission belt 51 are provided below the platen 40.

[0066] The conveyance unit 24 includes a plurality of driven rollers 54. The driven rollers 54 have a cylindrical shape, and the circumferential surface is formed of a flexible material such as a rubber material. The plurality of driven rollers 54 are arranged to be rotatable along the long side direction of the conveyance roller 50. Each of the driven rollers 54 is biased so that its circumferential surface contacts the circumferential surface of the conveyance roller 50. Thus, the conveyance roller 50 and the driven rollers 54 are arranged to contact in a state where their circumferential surfaces face each other.

[0067] The conveyance roller 50 is arranged on the side of the lower guide member 32, and the driven rollers 54 are arranged on the side of the paper pressing member 34.

[0068] It should be noted that the conveying roller 50 can also be arranged on the side of the lower guiding member 32, in other words, it can also be arranged on the side of the stamping plate 40. In addition, for example, the conveying unit 24 can also be provided with a conveyor belt capable of moving on the upper surface of the stamping plate 40 to replace the conveying roller 50.

[0069] In the conveying unit 24, it is driven by a conveying motor 52. The conveying roller 50 is rotationally driven by a transmission belt 51, and the driven roller 54 is rotationally driven in a driven manner. Thus, the label paper 100 loaded between the lower guiding 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 rotates and drives.

[0070] The label paper 100 sent out from the paper guiding unit 30 placed on the flat surface 33 passes through between the conveying roller 50 and the driven roller 54, and is clamped between the conveying roller 50 and the driven roller 54. In this state, as the conveying roller 50 rotates, the label paper 100 is conveyed to the printing unit 22.

[0071] In the printing apparatus 1, a conveying roller pair is formed by the conveying roller 50 and the driven roller 54.

[0072] In the printing apparatus 1, a label detector 70 is provided on the conveying path R. The label detector 70 detects the front end and the rear end of the label paper 100 and the front end and the rear end of the label.

[0073] The label detector 70 of the present embodiment is arranged on the downstream side of the paper guiding unit 30 and on the upstream side of the conveying roller 50. The label detector 70 is, for example, an optical transmission type sensor, which has a light emitting portion 72 on the lower surface side of the label paper 100 in the conveying path R and a light receiving portion 74 on the upper surface side of the label paper 100. The light emitting portion 72 and the light receiving portion 74 are relatively arranged at an interval that allows the label paper 100 to pass through in the vertical direction. That is, the light emitting portion 72 and the light receiving portion 74 are relatively arranged along the thickness direction of the label paper 100. Thus, the light emitting portion 72 and the light receiving portion 74 are arranged at substantially the same position in the left-right direction.

[0074] It should be noted that the label detector 70 can also be arranged on the downstream side of the conveying roller 50 and on the upstream side of the printing head 42.

[0075] In addition, for example, the light emitting portion 72 can be arranged on the side of the lower guiding member 32, and the light receiving portion 74 can be arranged on the side of the paper pressing member 34. In this case, the light emitting portion 72 can be arranged on the side of the stamping plate 40, and the light receiving portion 74 can be arranged on the side of the printing head 42.

[0076] In the label detector 70, the light emitting unit 72 and the light receiving unit 74 can be arranged at positions where the light receiving unit 74 can receive the light emitted from the light emitting unit 72 with a predetermined signal intensity. In this case, the output value representing the light reception amount of the light receiving unit 74 is different when there is no label paper 100 directly below the light receiving unit 74, when there is a backing paper, and when there is a label. That is, the signal intensities 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 end and the rear end of the label paper 100 and the front end and the rear end of the label based on the output value representing the light reception amount of the light receiving unit 74.

[0077] The cutter unit 110 is arranged on the downstream side of the print head 42 in the conveying direction F, in other words, on the left side of the print head 42. The cutter unit 110 includes a fixed blade 112 and a movable blade 114 arranged across the conveying path R, and the movable blade 114 is connected to a driving device such as a motor that drives the cutter through gears or the like. In the cutter unit 110, when the motor is driven, the movable blade 114 moves toward the fixed blade 112 to cut the label paper 100. The cutter unit 110 can be a unit that performs a cut to retain a part in the width direction of the label paper 100, or can be 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 cutter unit 110 and discharges it from the paper discharge port 14.

[0078] It should be noted that the cutter unit 110 can also be formed separately from the printing device 1. For example, it can be arranged to be detachable from the left side surface of the printing device 1.

[0079] The printing device 1 includes a control board 18 that controls each part of the printing device 1. The control board 18 includes a CPU, a ROM, a RAM, etc. as an operation execution unit. Firmware that can be executed by the CPU, data related to the firmware, etc. are stored non-volatilely in the ROM of the control board 18. In addition, data related to the firmware executed by the CPU is temporarily stored in the RAM. The control board 18 can also include other peripheral circuits, etc. The control board 18 can also include a storage unit that can store various programs and data such as control programs and data related to these control programs non-volatilely.

[0080] The control board 18 is formed to be able to detect operations on the printing device 1 and the conveyance amount of the label paper 100.

[0081] The control board 18 is formed to be able to control driving devices such as the conveyance motor 52 included in the printing device 1.

[0082] The control substrate 18 supplies voltages to a pump that supplies ink from an ink tank in the print head 42 and piezoelectric elements provided in nozzle portions 41 to 47 of the print head 42 to cause them to operate. Thereby, in the printing apparatus 1, ink droplets are ejected from the respective nozzles of the nozzle portions 41 to 47 to form dots.

[0083] As Figure 8 shown, the frame 4 is housed inside the apparatus housing 10. The frame 4 is a framework member on which various mechanism portions such as the storage portion 20, the printing portion 22, the conveyance portion 24, and the control substrate 18 of the printing apparatus 1 are mounted and which supports these mechanism portions. The printing apparatus 1 is formed by covering the frame 4 on which various mechanism portions are mounted with respective exterior panels 9.

[0084] Figure 4 is a perspective view of the left side panel 17. In Figure 4 is shown the left side panel 17 as viewed from the right.

[0085] Next, each of the exterior panels 9 will be described.

[0086] As Figure 4 shown, the left side panel 17 is formed of a flat plate-like material. The left side panel 17 has a flat portion 82 that forms the left side of the apparatus housing 10. In the left side panel 17, a folded-back portion 84 that overlaps the flat portion 82 from the right is formed at an edge 80 on the back side.

[0087] The folded-back portion 84 is arranged such that an edge portion of the edge 80 on the back side is bent 180 degrees by a predetermined width dimension and extends toward the front surface side, that is, formed by so-called hemming bending processing.

[0088] A first standing portion 85 is provided at the front end portion of the folded-back portion 84. The first standing portion 85 is bent such that the front end portion of the folded-back portion 84 extends toward the right side by a predetermined width dimension, that is, formed by so-called flange bending processing. In the present embodiment, the first standing portion 85 is formed to stand up from the folded-back portion 84 at substantially a right angle. The plane of the first standing portion 85 is arranged to face the back of the apparatus housing 10.

[0089] It should be noted that as long as the first standing portion 85 stands up from the folded-back portion 84, it is not limited to a right angle and may stand up at any angle.

[0090] In the present embodiment, the left side panel 17 corresponds to the "first surface".

[0091] Figure 5 is a perspective view of the back panel 6. In Figure 5 is shown the back panel 6 as viewed from the front.

[0092] As Figure 5As shown, the back panel 6 is formed of a flat plate-like material. The back panel 6 has a flat portion 89 that forms the back surface of the device housing 10. In the back panel 6, a second upright portion 87 is provided at an edge 86 on the left side surface side. The second upright portion 87 is bent so that the edge portion of the edge 86 extends toward the front surface side with a predetermined width dimension, that is, it is formed by so-called flange bending. In the present embodiment, the second upright portion 87 is formed to stand up from the flat portion 89 at a substantially right angle. The plane of the second upright portion 87 is arranged to face the left side surface of the device housing 10.

[0093] In the back panel 6, similarly to the edge 86, a second upright portion 87 is provided at an edge 88 at the upper end. The second upright portion 87 of the edge 88 is formed by bending the edge portion of the edge 88 to extend toward the front surface side with a predetermined width dimension.

[0094] In the present embodiment, the back panel 6 corresponds to the "second surface".

[0095] Figure 6 is Figure 2 a sectional view taken along plane VI.

[0096] As Figure 2 shown, in the device housing 10, the left side surface panel 17 and the back panel 6 are arranged such that the edges 80 and 86 are butted across the entire long side direction.

[0097] As Figure 6 shown, in the present embodiment, the edges 80 and 86 are arranged with a predetermined gap therebetween so that the left side surface panel 17 and the back panel 6 do not flex due to dimensional tolerances or the like.

[0098] In the case where the left side surface panel 17 and the back panel 6 are arranged in this way, the plane of the second upright portion 87 is arranged to face the plane of the folded-back portion 84.

[0099] Moreover, the front end of the second upright portion 87 is arranged to extend toward the plane of the first upright portion 85. In other words, the front end of the second upright portion 87 is arranged to face the plane of the first upright portion 85 when viewed from a direction perpendicular to the back panel 6, that is, when viewed from the back of the device housing 10.

[0100] Therefore, when the device housing 10 is viewed from above, the gap V between the edges 80 and 86 is a substantially L-shape that extends from the back toward the front and then toward the right.

[0101] In this way, the left side surface panel 17 and the back panel 6 form a so-called labyrinth structure by providing a substantially L-shaped gap V at the portion where the edges 80 and 86 are butted.

[0102] Thus, the device housing 10 can shield components housed inside the device housing 10 from the outside without providing other components such as a sealing member for the gap V between the covering edge 80 and the edge 86. Therefore, the device housing 10 can suppress an increase in the number of parts and the manufacturing man-hours, and can ensure its function as an exterior member and a shielding body while suppressing an increase in cost. Moreover, with the above structure, the device housing 10 can improve the designability. In addition, in the device housing 10, since such a labyrinth structure is provided at the edges 80 and 86, while suppressing a reduction in the internal space of the device housing 10, components housed inside the device housing 10 can be shielded from the outside.

[0103] In addition, the device housing 10 can prevent trash, dust, bugs, etc. from entering through the gap V. Also, the left side panel 17 and the back panel 6 are formed of a metallic material. Therefore, in the printing device 1, adverse effects on the outside of the printing device 1 caused by electromagnetic waves leaking from inside the device housing 10 and malfunctions in each part of the printing device 1 caused by electromagnetic waves entering from the outside of the device housing 10 into the inside are suppressed.

[0104] In addition, the device housing 10 is configured such that the edges 80 and 86 are provided with the gap V, so that even when the left side panel 17 and the back panel 6 are subjected to a predetermined external force, flexure and deformation in the left side panel 17 and the back panel 6 can be suppressed.

[0105] As Figure 6 shown, when viewed from the back of the device housing 10, at least a part of the first standing portion 85 is covered by the back panel 6 from the back. When viewed from the left side of the device housing 10, the second standing portion 87 is covered by the left side panel 17 from the left. In addition, the edge 80 and the edge 86 are arranged not to engage with each other.

[0106] Thus, in the device housing 10, one of the left side panel 17 and the back panel 6 can be removed without removing the other. Therefore, in the device housing 10, the left side panel 17, the back panel 6, or the components housed in the device housing 10 can be easily replaced.

[0107] It should be noted that the left side panel 17 and the back panel 6 are arranged with a gap V therebetween. However, this is not limiting, and the left side panel 17 and the back panel 6 may be arranged such that the plane of the second standing portion 87 and the plane of the folding portion 84 are in contact with each other. In addition, for example, the left side panel 17 and the back panel 6 may be arranged such that the front end of the second standing portion 87 and the plane of the first standing portion 85 are in contact with each other. That is, the edge 80 and the edge 86 may be in contact with each other.

[0108] Figure 7It is a perspective view of the left top panel 13. Figure 7 It is a perspective view obtained by observing the left top panel 13 from the back side.

[0109] Next, the left top panel 13 will be described.

[0110] As shown in Figure 2 and Figure 7 , the left top panel 13 is formed by bending a flat plate-like material upward into a protruding arch shape. The upper end portion of the left top panel 13 is formed as a plane parallel to the left-right direction. The left side panel 17 has a flat surface portion 92 that forms the back side on the left in the top surface of the device housing 10.

[0111] In the left top panel 13, a folded-back portion 94 that overlaps with the flat surface portion 92 from the back side is formed at an edge 90 located on the back side of the device housing 10 and extending along the left-right direction of the top surface of the device housing 10.

[0112] The folded-back portion 94 is arranged such that the edge portion of the edge 90 on the back side is bent 180 degrees with a predetermined width dimension and extends toward the front surface side, that is, formed by so-called hemming bending processing.

[0113] The first upright portion 95 is provided at the front end portion of the folded-back portion 94. The first upright portion 95 is bent such that the front end portion of the folded-back portion 94 extends downward with a predetermined width dimension, that is, formed by so-called flange bending processing. In the present embodiment, the first upright portion 95 is formed to stand up from the folded-back portion 94 at a substantially right angle. The plane of the first upright portion 95 is arranged to face the back of the device housing 10.

[0114] In the present embodiment, the left top panel 13 corresponds to the "first surface".

[0115] In the first upright portion 95, extension portions 96 that further extend downward from the first upright portion 95 are provided at the left and right ends in the long side direction. Threaded holes 97 that penetrate in the front-rear direction are provided in the extension portions 96.

[0116] A plurality of engaging pieces 99 formed by bending the edge portions of the extension portions 96 forward are provided on the extension portions 96. The engaging pieces 99 have a protruding shape that protrudes forward from the extension portions 96.

[0117] The engaging pieces 99 correspond to the "protruding portions".

[0118] Figure 8 It is a perspective view obtained by observing the printing device 1 from the back side. In Figure 8 , the back panel 6 is shown by a dashed line, and the inside of the printing device 1 is shown in a way that transmits the back panel 6.

[0119] As shown in Figure 8As shown, the left top surface panel 13 covers the frame 4 from above. In this case, each engaging piece 99 engages with the engaging hole 102 provided in the frame 4. Moreover, the extension portion 96 is threadedly fixed to the frame 4 by a threaded member 104 that passes through the threaded hole 97.

[0120] Thus, the left top surface panel 13 is fixed to the frame 4. In this way, the device housing 10 is fixed to the frame 4 housed in the device housing 10 by the left top surface panel 13, and the strength can be improved.

[0121] Moreover, in the printing device 1, when assembling the printing device 1, the left top surface panel 13 can be positioned with higher precision. Furthermore, in the printing device 1, since the alignment of the respective parts forming the printing device 1 becomes easy when assembling the printing device 1, the assembly time can be shortened and the work efficiency can be improved.

[0122] The first upright portion 95 and the extension portion 96 are covered by the back panel 6 from the rear. Thus, in the printing device 1, the fastening structure between the left top surface panel 13 and the frame 4 can be prevented from being exposed to the outside of the device housing 10. In other words, in the device housing 10, the fastening structure for fixing the left top surface panel 13 can be prevented from being exposed to the outside. Therefore, the designability of the device housing 10 can be improved.

[0123] Each of the above embodiments is merely a way of showing a specific example to which the present utility model is applied. The present utility model is not limited to the configurations of the above embodiments and can be implemented in various ways without departing from the gist of the utility model.

[0124] In the above embodiment, it is assumed that the second upright portion 87 is provided on the edges 86 and 88 by flange bending. However, it is not limited thereto, and hemming bending can also be performed on the edges 86 and 88.

[0125] When hemming bending is performed on the edge 86, the bent portion of the edge 86 formed by hemming bending can also be arranged to be opposite to the plane of the first upright portion 85 when viewed from the back of the device housing 10. When hemming bending is performed on the edge 88, the bent portion of the edge 88 formed by hemming bending can also be arranged to be opposite to the plane of the first upright portion 95 when viewed from the back of the device housing 10.

[0126] In addition, for example, bending processing may not be performed on the edges 86 and 88.

[0127] Without performing bending processing on the edge 86, the edge 86 can also be configured to be opposite to the plane of the first upright portion 85 when viewed from the back of the device housing 10. Without performing bending processing on the edge 88, the edge 88 can also be configured to be opposite to the plane of the first upright portion 95 when viewed from the back of the device housing 10.

[0128] In the above-described embodiment, other devices such as a stripper and a cutter unit 110 that perform the process of peeling the label from the backing paper can also be provided on the left side surface of the printing device 1.

[0129] In the above-described embodiment, a line head type is illustrated as the print head 42, but it is not limited thereto, and a serial head type may also be used. In addition, the printing method of the print head 42 is not limited to an inkjet type.

[0130] In the above-described embodiment, a label printer is illustrated as the printing device 1. However, the printing device 1 is not limited to a label printer. The printing device 1 only needs to be a device having 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 can also be a large-format printer, a printing machine for dyeing, or the like.

[0131] In addition, for example, the device housing 10 is not limited to being used for a printing device, and can also be used for other electronic devices such as a desktop housing of a personal computer, various measuring devices, robots, and home printers.

[0132] In the above-described embodiment, directions such as horizontal and vertical and various shapes, unless otherwise specified, include so-called equivalent ranges that have the same effects as these directions and shapes.
