[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the description, directions such as front, back, left, right, and up and down are the same as directions relative to the printing device 1 unless otherwise specified. Also, the symbol FR shown in each drawing indicates the front of the printing device 1 when the printing device 1 is installed for use, the symbol UP indicates the upper side of the printing device 1, and the symbol LH indicates the left side of the printing device 1.

[0009] 1 is a perspective view of the printing apparatus 1 as seen from the right. In FIG. 1, the portions of the exterior panel 9 that cover the transport path R are indicated by dots. The printing device 1 is a so-called line-type inkjet printer that includes 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.

[0010] The printing medium used for printing by the printer 1 is a cut sheet cut to a predetermined size or a continuous sheet. These sheets are made of paper, synthetic resin, etc. These sheets may be, for example, fine paper that has been surface-treated to enhance the ink absorption and fixation properties suitable for inkjet printing.

[0011] Examples of the continuous sheet include roll paper that is stored in the printer 1 in a rolled state, and fanfold paper that is supplied in a folded state to the printer 1 from outside the printer 1. Examples of roll paper include plain paper or fine paper wound into a roll, as well as label paper made by arranging standard size labels with adhesive on the backing on a release paper and winding them into a roll.

[0012] In this embodiment, labels of a predetermined size with adhesive on the backing are placed on a mount on which a long release paper that can be peeled off from the adhesive is formed, and the rolled label paper 100 is used as the print medium. On the label paper 100, multiple labels are arranged at equal intervals in the longitudinal direction of the mount. The printing device 1 transports the label paper 100 and prints characters and images on the printing surface of each label on the label paper 100. In other words, the printing device 1 is a label printer. The label paper 100 is shown in FIG.

[0013] FIG. 2 is a perspective view of the printing device 1 as viewed from the rear side. 1 and 2, the printing device 1 includes a device case 10, which is a substantially rectangular parallelepiped housing. The device case 10 is formed by combining a plurality of exterior panels 9 that form the sides, front, back, etc. In the present embodiment, the exterior panels 9 are all made of a metal material. However, the present invention is not limited to this, and the exterior panels 9 may be made of a resin material. For example, the exterior panels 9 may be made of a combination of a metal material and a resin material.

[0014] The device case 10 has exterior panels 9, which include a front panel 11, a left top panel 13, a right top panel 15, a left side panel 17, a paper exit panel 3, a right side panel 5, a rear panel 6, and a bottom panel 7. As shown in FIG. 1, the front panel 11 forms the lower left half of the front surface of the device case 10. The right side panel 5 forms the right side of the device case 10 .

[0015] The left top panel 13 forms the left rear side of the top surface of the device case 10 . The right top panel 15 forms the right rear side of the top surface of the device case 10 . The top surface of the device case 10 is stepped. The top surface portion located on the left side of the device case 10 is located higher than the top surface portion located on the right side. Therefore, the left top panel 13 is located above the right top panel 15.

[0016] 2, the left side panel 17 forms the left side of the device case 10 excluding the vicinity of a corner formed by the front and top surfaces on the left side of the device case 10. The paper exit panel 3 is a rectangular panel on the left side located at the corner. The rear panel 6 forms the entire rear surface of the device case 10. The bottom panel 7 forms the entire bottom surface of the device case 10.

[0017] A display / operation panel 12 is provided on the front surface of the device case 10, in a location in the upper half toward the left. The display / operation panel 12 has a display 60 that functions as a display unit that displays predetermined information, and operators 62 such as operation buttons arranged on a flat surface 61. The display / operation panel 12 has a flat plate shape with a predetermined thickness. The display / operation panel 12 is arranged so that its longitudinal direction extends in the left-right direction.

[0018] 1, a paper cover 16 is provided on the device case 10 in an openable and closable manner. The paper cover 16 forms part of the front surface and part of the top surface of the printing device 1. The paper cover 16 is formed from a position near the right side of the front surface of the device case 10 to a position near the front of the top surface of the device case. In this embodiment, the paper cover 16 forms part of the top surface of the printing device 1. The paper cover 16 is formed so as to be openable and closable by rotating about a connecting portion 120 provided on the top surface of the device case 10 at approximately the center in the front-rear direction.

[0019] A storage section 20 that stores label paper 100 is provided inside the paper cover 16. In the printing device 1, by opening the paper cover 16, it is possible to load the label paper 100 wound in a roll into the storage section 20. In the printing device 1, by opening the paper cover 16, it is possible to access the inside of the device case 10 from the outside, and it is possible to operate the storage section 20 and each section related to transport.

[0020] A printing unit cover 19 is provided on the left side of the paper cover 16 in the device case 10. The printing unit cover 19 forms a portion of the top surface that is close to the front surface of the device case 10. The printing unit cover 19 is formed to be able to rotate around a connecting portion 121 provided in approximately the center of the top surface of the device case 10, and to be opened and closed. A printing unit 22 that prints on the label paper 100 is provided below the printing unit cover 19. In other words, the printing unit cover 19 covers the printing unit 22 from above.

[0021] 2, a slit-shaped paper outlet 14 extending in the front-rear direction is formed in the left side surface located to the left of the device case 10, approximately in the center toward the front when viewed from the left side surface. In the printing device 1, printed label paper 100 is discharged from the paper outlet 14. The paper outlet 14 is provided in the paper outlet panel 3. In this embodiment, the side surface on which the paper discharge outlet 14 is formed is not provided with an operation unit, a display unit, or the like.

[0022] FIG. 3 is a rear view of the main parts of the printing device 1, showing the various parts related to the transport path R. As shown in FIG. As shown in FIG. 8, the printing device 1 includes a storage unit 20 that stores label paper 100, a printing unit 22 that prints on the label paper 100, and a transport unit 24 that transports the label paper 100 from the storage unit 20 to the printing unit 22. 3, 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 transport unit 24 is provided below the printing unit 22.

[0023] The storage unit 20 includes a roll shaft 26 on which the label paper 100 is attached. The roll shaft 26 is a rod-shaped member that is rotatable in the circumferential direction. The label paper 100 is stored in the storage unit 20 by inserting the roll shaft 26 through the center of the roll of the label paper 100. A drive device such as a motor may be connected to the roll shaft 26, and the roll shaft 26 may rotate in response to the drive device. In the printing device 1, the label paper 100 rotates as the roll shaft 26 rotates.

[0024] In the printing device 1, a transport path R is formed along which one end of the label paper 100 attached to a roll shaft 26 is pulled out and transported to the paper discharge outlet 14. In the transport path R, a tension lever 28 is attached above the label paper 100 stored in the storage section 20. The tension lever 28 is formed in a column shape that has a curved surface in the circumferential direction and extends in the front-to-rear direction. The tension lever 28 applies tension to the label paper 100 to prevent it from sagging. One end of the label paper 100 is pulled upward and comes into contact with the tension lever 28. After being bent by the tension lever 28, the label paper 100 extends to the left.

[0025] A paper guide unit 30 is provided to the left of the tension lever 28. The paper guide unit 30 guides the label paper 100 to the left, and prevents the label paper 100 from skewing or shifting in its transport. The paper guide unit 30 comprises 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 .

[0026] The lower guide member 32 has a flat surface 33 extending in the left-right direction. The flat surface 33 has a width dimension along the front-rear direction of the device case 10 that is longer than the width dimension of the label paper 100. The label paper 100 is placed on and supported by the flat surface 33 of the lower guide member 32.

[0027] The paper pressing member 34 is located above the label paper 100 facing the lower guide member 32, and prevents the label paper 100 from floating up. The paper pressing members 34 are arranged at each of the 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 rotatable about an axis of rotation parallel to the conveying direction F. The paper pressing members 34 are rotatable from a position facing the flat surface 33 with a specified gap therebetween, to a position separated from the flat surface 33.

[0028] The label paper 100 is placed on the flat surface 33 with each of the paper holding members 34 positioned away from the flat surface 33. After this, the paper holding members 34 are rotated to a position facing the flat surface 33 with a specified gap therebetween, so that the label paper 100 is sandwiched between the lower guide member 32 and the paper holding members 34. The label paper 100 is conveyed in the paper guiding unit 30 while being sandwiched between a lower guide member 32 and a paper pressing member 34. The paper guiding unit 30 functions as a guide for the label paper 100.

[0029] A printing section 22 that prints on the label paper 100 is provided to the left of the paper guide unit 30. The printing section 22 includes a platen 40 and a print head 42. The print head 42 in this embodiment ejects ink of four colors, C (cyan), M (magenta), Y (yellow), and K (black), to form dots on the printing surface of the label. The print head 42 includes a nozzle section 41 that ejects K (black) ink, a nozzle section 43 that ejects C (cyan) ink, a nozzle section 45 that ejects M (magenta) ink, and a nozzle section 47 that ejects Y (yellow) ink. The nozzle sections 41 to 47 have a plurality of nozzles that eject ink arranged in rows in the width direction of the label paper 100. The nozzles of each of the nozzle sections 41 to 47 are arranged in a direction that intersects with the transport direction F. In this embodiment, the direction in which the nozzles are arranged is a direction perpendicular to the transport 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 unit.

[0030] 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 row of the nozzle units 41-47 is formed to be at least as wide as or wider than the printable range of the label paper 100. In this embodiment, the printable range corresponds to the printing surface of the label. In this embodiment, a configuration example is given in which the nozzle sections 41, 43, 45, and 47 are arranged in this order along the transport direction F of the label paper 100, but the order in which the nozzles of each color are arranged in the transport direction F is arbitrary.

[0031] The platen 40 has a flat surface that is arranged parallel to the transport direction F. This flat surface is located below the transport path R and faces the print head 42. The nozzle portions 41-47 and the platen 40 are arranged with a gap therebetween, which is a so-called platen gap. The platen 40 has a flat upper surface that supports the label paper 100 from below. The platen 40 is provided over at least the entire printing range of the printing unit 22. The upper surface of the platen 40 is disposed substantially horizontally when the printing device 1 is installed and in use.

[0032] The transport section 24 includes a cylindrical transport roller 50. The transport roller 50 is disposed so that its longitudinal direction extends in a direction intersecting the transport direction F, and is provided so as to be freely rotatable in the circumferential direction. The transport roller 50 is disposed between the left end of the paper guiding unit 30 and the right end of the platen 40 in the transport direction F.

[0033] A driven wheel is provided at one end of the transport roller 50. A transmission belt 51 is wound around the driven wheel. The transmission belt 51 is wound around a drive shaft of a transport motor 52. This allows the transport roller 50 and the transport motor 52 to be connected via the transmission belt 51. The transport motor 52 is a drive device that rotates the transport roller 50. The transport motor 52 and the transmission belt 51 are provided below the platen 40.

[0034] The transport section 24 includes a plurality of driven rollers 54. The driven rollers 54 are cylindrical, and the peripheral surface is formed of a flexible material such as rubber. The plurality of driven rollers 54 are rotatably arranged along the longitudinal direction of the transport roller 50. Each of the driven rollers 54 is biased so that the peripheral surface thereof contacts the peripheral surface of the transport roller 50. As a result, the transport roller 50 and the driven roller 54 are arranged in contact with each other with their peripheral surfaces facing each other. The transport roller 50 is disposed on the lower guide member 32 side, and the driven roller 54 is disposed on the paper pressing member 34 side.

[0035] The transport rollers 50 may be disposed on the lower guide member 32 side, in other words, on the platen 40 side. Also, for example, the transport unit 24 may include a transport belt that is movable on the upper surface of the platen 40, instead of the transport rollers 50.

[0036] In the conveying section 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 sandwiched between the conveying roller 50 and the driven roller 54, and is conveyed to the printing section 22 as the conveying roller 50 is rotated.

[0037] The label paper 100 placed on the flat surface 33 and sent out from the paper guiding unit 30 is inserted and sandwiched between the transport roller 50 and the driven roller 54. In this state, the transport roller 50 rotates, so that the label paper 100 is transported to the printing section 22. In the printing device 1, the transport roller 50 and the driven roller 54 form a transport roller pair.

[0038] The printer 1 is provided with a label detector 70 on the transport path R. The label detector 70 detects the leading and trailing ends of the label paper 100 and the leading and trailing ends of the labels. The label detector 70 of this embodiment is positioned downstream of the paper guiding unit 30 and upstream of the transport roller 50. The label detector 70 is, for example, an optical transmission sensor that has a light-emitting unit 72 on the underside of the label paper 100 and a light-receiving unit 74 on the upper side of the label paper 100 on the transport path R. The light-emitting unit 72 and the light-receiving unit 74 are positioned opposite each other in the up-down direction with a distance large enough to allow the label paper 100 to pass through. In other words, the light-emitting unit 72 and the light-receiving unit 74 are positioned opposite each other in the thickness direction of the label paper 100. As a result, the light-emitting unit 72 and the light-receiving unit 74 are positioned at approximately the same position in the left-right direction.

[0039] The label detector 70 may be disposed downstream of the transport rollers 50 and upstream of the print head 42. Also, 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.

[0040] In the label detector 70, the light-emitting unit 72 and the light-receiving unit 74 can be disposed in a position where the light-receiving unit 74 can receive the light emitted from the light-emitting unit 72 at a predetermined signal intensity. In this case, the output value indicating the amount of light received by the light-receiving unit 74 differs depending on whether there is no label paper 100 directly below the light-receiving unit 74, whether there is a backing paper, or whether there is a label. In other words, the signal intensity of the light emitted from the light-emitting unit 72, the light transmitted through the backing paper, and the light transmitted through the label are different from one another. For this reason, the label detector 70 can detect the leading and trailing ends of the label paper 100 and the leading and trailing ends of the label by the output value indicating the amount of light received by the light-receiving unit 74.

[0041] A cutter unit 110 is disposed downstream of the print head 42 in the transport direction F, in other words, to the left of the print head 42. The cutter unit 110 includes a fixed blade 112 and a movable blade 114 disposed on either side of the transport path R, and the movable blade 114 is connected via a gear or the like to a drive device such as a motor that drives the cutter. When the motor is driven, the cutter unit 110 moves the movable blade 114 toward the fixed blade 112 and cuts the label paper 100. The cutter unit 110 may be one that leaves a portion of the label paper 100 uncut in the width direction, or may be one that cuts the label paper 100 completely. The printing device 1 cuts the label paper 100 printed by the print head 42 to a predetermined length by the cutter unit 110 and discharges it from the paper discharge port 14. The cutter unit 110 may be formed separately from the printing device 1 and may be detachably provided on the left side surface of the printing device 1, for example.

[0042] 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, and the like as an arithmetic execution unit. The ROM of the control board 18 stores firmware executable by the CPU, data related to the firmware, and the like in a non-volatile manner. The RAM also stores data related to the firmware executed by the CPU, and the like temporarily. The control board 18 may include other peripheral circuits, and the like. The control board 18 may include a storage unit capable of non-volatilely storing various programs and data, such as control programs and data related to these control programs.

[0043] The control board 18 is configured to be able to detect operations on the printing device 1 and the conveyance amount of the label paper 100. The control board 18 is formed so as to be capable of controlling the drive devices provided in the printing device 1, such as the transport motor 52. The control board 18 supplies voltage to the pump that supplies ink from the ink tank in the print head 42 and the piezoelectric elements provided in the nozzle portions 41-47 of the print head 42 to operate them. As a result, in the printing device 1, ink droplets are ejected from each nozzle of the nozzle portions 41-47 to form dots.

[0044] As shown in Fig. 8, a frame 4 is housed inside the device case 10. The frame 4 is a framework member to which various mechanical parts of the printing device 1, such as the storage unit 20, printing unit 22, transport unit 24, and control board 18, are attached and which supports the mechanical parts. The printing device 1 is formed by covering the frame 4, to which the various mechanical parts are attached, with each of the exterior panels 9.

[0045] Fig. 4 is a perspective view of the left side panel 17. Fig. 4 shows the left side panel 17 as viewed from the right. Next, each of the exterior panels 9 will be described. 4, left side panel 17 is formed of a flat plate material. Left side panel 17 has a flat portion 82 that forms the left side of device case 10. In left side panel 17, an end edge 80 located on the rear side is formed with a folded portion 84 that overlaps flat portion 82 from the right. The folded-back portion 84 is formed by a so-called hemming process in which the edge of the end side 80 located on the rear side is folded 180 degrees in a predetermined width dimension and arranged to extend toward the front side.

[0046] A first standing portion 85 is provided at the tip of the folded portion 84. The first standing portion 85 is formed by a so-called flange bending process in which the tip of the folded portion 84 is bent so as to extend to the right side surface side with a predetermined width dimension. In this embodiment, the first standing portion 85 is formed so as to stand at a substantially right angle from the folded portion 84. The flat surface of the first standing portion 85 is disposed opposite to the rear surface of the device case 10. In addition, the first upright portion 85 may be upright at any angle, not limited to a right angle, as long as it is upright from the folded-back portion 84 . In this embodiment, the left side panel 17 corresponds to the "first side."

[0047] Fig. 5 is a perspective view of the rear panel 6. Fig. 5 shows the rear panel 6 as viewed from the front. As shown in FIG. 5, the rear panel 6 is formed of a flat plate material. The rear panel 6 has a flat portion 89 that forms the rear surface of the device case 10. A second standing portion 87 is provided on an end edge 86 located on the left side surface of the rear panel 6. The second standing portion 87 is formed by a so-called flange bending process in which an edge portion of the end edge 86 is bent so as to extend to the front surface side with a predetermined width dimension. In this embodiment, the second standing portion 87 is formed to stand at a substantially right angle from the flat portion 89. The flat surface of the second standing portion 87 is disposed opposite to the left side surface of the device case 10.

[0048] In the rear panel 6, an end side 88 located at the upper end is provided with a second standing portion 87, similar to the end side 86. The second standing portion 87 of the end side 88 is formed by folding an edge of the end side 88 so that it extends toward the front side with a predetermined width dimension. In this embodiment, the rear panel 6 corresponds to the "second surface."

[0049] FIG. 6 is a cross-sectional view in plane VI of FIG. As shown in FIG. 2, in the device case 10, the left side panel 17 and the rear panel 6 are arranged such that the end edge 80 and the end edge 86 are butted against each other over the entire lengthwise direction. As shown in FIG. 6, in this embodiment, end edge 80 and end edge 86 are disposed at a predetermined interval so that left side panel 17 and rear panel 6 do not sag due to dimensional tolerances or the like.

[0050] When the left side panel 17 and the rear panel 6 are arranged in this manner, the plane of the second standing portion 87 is arranged to face the plane of the folded-back portion 84 . Furthermore, the tip of the second standing portion 87 is disposed so as to extend toward the plane of the first standing portion 85. In other words, the tip of the second standing portion 87 is disposed so as to face the plane of the first standing portion 85 when viewed from a direction perpendicular to the rear panel 6, i.e., when viewed from the rear of the device case 10. Therefore, the gap V between the end side 80 and the end side 86 is generally L-shaped in plan view of the device case 10, extending forward from the rear surface and then extending to the right.

[0051] In this manner, a generally L-shaped gap V is provided between the left side panel 17 and the rear panel 6 at the location where the end edge 80 and the end edge 86 butt against each other, thereby forming a so-called labyrinth structure.

[0052] As a result, the device case 10 can shield the members housed inside the device case 10 from the outside without providing other members such as a sealing member that covers the gap V between the end edge 80 and the end edge 86. Therefore, the device case 10 can suppress an increase in the number of parts and manufacturing steps, and can ensure its function as an exterior member and a shield while suppressing an increase in costs. In addition, the device case 10 can improve its design due to the above-mentioned structure. Furthermore, in the device case 10, such a labyrinth structure is provided between the end edge 80 and the end edge 86, so that the members housed inside the device case 10 can be shielded from the outside while suppressing a reduction in the internal space of the device case 10.

[0053] Additionally, the device case 10 can prevent dirt, dust, insects, and the like from entering through the gap V. Furthermore, the left side panel 17 and the rear panel 6 are formed from a metal material. This prevents the printer 1 from having adverse effects on the outside of the printer 1 caused by the leakage of electromagnetic waves generated inside the device case 10, and prevents malfunctions in various parts of the printer 1 caused by electromagnetic waves entering the inside of the device case 10 from the outside.

[0054] Furthermore, by arranging end edge 80 and end edge 86 of device case 10 with gap V provided therebetween, bending and deformation of left side panel 17 and rear panel 6 can be suppressed even when left side panel 17 and rear panel 6 are subjected to a predetermined external force.

[0055] 6, at least a portion of the first upright portion 85 is covered from the back by the rear panel 6 in a rear view of the device case 10. The second upright portion 87 is covered from the left by the left side panel 17 in a left side view of the device case 10. In addition, the end edge 80 and the end edge 86 are disposed without engaging with each other. As a result, in device case 10, left side panel 17 and rear panel 6 can be removed one without removing the other. Therefore, in device case 10, left side panel 17, rear panel 6, or parts housed in device case 10 can be easily replaced.

[0056] It is noted that the left side panel 17 and the rear panel 6 are arranged with a gap V therebetween. However, this is not limiting, and the left side panel 17 and the rear panel 6 may be arranged such that the plane of the second standing portion 87 and the plane of the folded-back portion 84 abut against each other. Furthermore, for example, the left side panel 17 and the rear panel 6 may be arranged such that the tip of the second standing portion 87 and the plane of the first standing portion 85 abut against each other. In other words, the end edge 80 and the end edge 86 may abut against each other.

[0057] Fig. 7 is a perspective view of the left top panel 13. Fig. 7 is a perspective view of the left top panel 13 as viewed from behind. Next, the left top panel 13 will be described. 2 and 7, left top panel 13 is formed by bending a flat plate material into an arch shape that protrudes upward. Left top panel 13 is formed so that the upper end is a flat surface that is parallel to the left-right direction. Left side panel 17 has a flat surface 92 that forms the rear side of the top surface of device case 10 closer to the left. The left top panel 13 is located on the rear side of the device case 10 and has an end edge 90 extending along the left-right direction of the top surface of the device case 10, which has a folded portion 94 that overlaps the flat portion 92 from the rear side. The folded-back portion 94 is formed by a so-called hemming process in which the edge of the end side 90 located on the rear side is folded 180 degrees at a predetermined width dimension and arranged to extend toward the front side.

[0058] A first upright portion 95 is provided at the tip of the folded-back portion 94. The first upright portion 95 is formed by a so-called flange bending process in which the tip of the folded-back portion 94 is bent so as to extend downward with a predetermined width dimension. In the present embodiment, the first upright portion 95 is formed so as to stand at a substantially right angle from the folded-back portion 94. The flat surface of the first upright portion 95 is disposed opposite the rear surface of the device case 10. In this embodiment, the left top panel 13 corresponds to the "first surface."

[0059] The first standing portion 95 has extension portions 96 at both left and right ends in the longitudinal direction thereof, the extension portions 96 extending further downward from the first standing portion 95. The extension portions 96 have screw holes 97 penetrating therethrough in the front-rear direction. The extending portion 96 is provided with a plurality of engagement pieces 99 formed by bending an edge of the extending portion 96 forward. The engagement pieces 99 each have a protruding shape that protrudes forward from the extending portion 96. The engagement piece 99 corresponds to the "protrusion."

[0060] 8 is a perspective view of the printer 1 from the rear side. In FIG. 8, the rear panel 6 is indicated by a dashed line, and the interior of the printer 1 is shown through the rear panel 6. 8, the left top panel 13 covers the frame 4 from above. In this case, each of the engagement pieces 99 engages with an engagement hole 102 provided in the frame 4. Furthermore, the extension portion 96 is screwed to the frame 4 by a screw member 104 inserted into the screw hole 97.

[0061] Thereby, the left top panel 13 is fixed to the frame 4. In this manner, by fixing the left top panel 13 to the frame 4 housed in the device case 10, the strength of the device case 10 can be improved. In addition, with the printing device 1, it is possible to more accurately position the left top panel 13 when assembling the printing device 1. Furthermore, with the printing device 1, it is easy to align the components that make up the printing device 1 when assembling the printing device 1, so that the assembly time can be shortened and work efficiency can be improved.

[0062] The first upright portion 95 and the extension portion 96 are covered from the rear by the rear panel 6. This prevents the fastening structure between the left top panel 13 and the frame 4 from being exposed to the outside of the device case 10 in the printing device 1. In other words, the fastening structure to which the left top panel 13 is fixed is prevented from being exposed to the outside in the device case 10. This allows the device case 10 to have an improved design.

[0063] The above-described embodiments are merely examples of the application of the present invention. The present invention is not limited to the configurations of the above-described embodiments, and can be embodied in various forms without departing from the spirit and scope of the invention.

[0064] In the embodiment described above, the second upright portion 87 is provided on the end sides 86 and 88 by flange bending. However, the present invention is not limited to this, and the end sides 86 and 88 may be subjected to hemming bending. When the end edge 86 is hemmed, the portion where the end edge 86 is bent by the hemming may be disposed opposite the plane of the first upright portion 85 when viewed from behind the device case 10. When the end edge 88 is hemmed, the portion where the end edge 88 is bent by the hemming may be disposed opposite the plane of the first upright portion 95 when viewed from behind the device case 10.

[0065] Also, for example, the end edges 86 and 88 do not need to be folded. When the end edge 86 is not bent, the end edge 86 may be disposed opposite the plane of the first standing portion 85 in a rear view of the device case 10. When the end edge 88 is not bent, the end edge 88 may be disposed opposite the plane of the first standing portion 95 in a rear view of the device case 10.

[0066] In the above-described embodiment, the left side surface of the printing device 1 may be provided with other devices such as a peeler that performs a process of peeling the label from the mount, a cutter unit 110, or the like.

[0067] In the above embodiment, a line head type print head 42 is exemplified, but this is not limiting and a serial head type may also be used. Furthermore, the printing method of the print head 42 is not limited to the inkjet type.

[0068] In the above-described embodiment, a label printer has been exemplified as the printing device 1. However, the printing device 1 is not limited to a label printer. The printing device 1 may be any device that includes a transport device that transports a print medium and a printing unit 22 that prints on the print medium. For example, the printing device 1 may be a large format printer, a textile printing machine, or the like.

[0069] Furthermore, for example, the device case 10 is not limited to being used in printing devices, but may also be used in other electronic devices such as desktop housings for personal computers, various measuring devices, robots, and home printers.

[0070] Unless otherwise specified, the horizontal, vertical and other directions and various shapes in the above-described embodiments include a so-called equivalent range in which the same action and effect is achieved as those directions and shapes.
