Description

[Technical field]

[0001] The present invention relates to electronic devices. [Background technology]

[0002] Conventionally, electronic devices equipped with an openable / closable door and a detector for detecting the open / closed state of the door have been known. For example, Patent Document 1 discloses an image forming device having a detectable member disposed on an opening / closing body, an open / close detector for detecting the open / closed state of the opening / closing body by detecting the detectable member, and a contact prevention unit for protecting the detectable member. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2007-101918 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the device described in Patent Document 1 has a problem in that it is difficult to prevent damage to the open / close detection means, which is the detection unit. In detail, a detected member is inserted into the open / close detection means through an opening, and the closed state of the opening / closing body is detected. The contact prevention unit protects the detected member by preventing contact between the detected member and the opening when an external force acts on the detected member in a direction different from that expected.

[0005] However, many of such devices stop operation when the opening / closing body is in the open state. Therefore, when checking the operation or adjusting the opening / closing body during maintenance work, an object simulating a detectable member may be inserted through the opening to intentionally erroneously detect the closed state of the opening / closing body. In this case, an unintended external force may act on the opening / closing detection means, causing the opening / closing detection means to be damaged. In other words, there has been a demand for an electronic device that suppresses damage to the detection unit. [Means for solving the problem]

[0006] The electronic device comprises a device main body, a door section supported on the device main body so as to be able to be opened and closed, a pressing section arranged on the door section, a deformation section which is deformable between an open state shape and a closed state shape depending on the open / closed state of the door section by the action of the pressing section, and which deforms into the closed state shape when a pressed surface is pressed by the pressing section, and a detection section which detects that the door section is in the closed state by being pressed by the pressing section via the pressed surface, wherein a hole is formed in the device main body through which the pressing section is inserted, and the pressed surface and the detection section are pressed by the pressing section inserted through the hole, the deformation section includes a flexible plate-like member, one end and the other end in the long side direction of the plate-like member are fixed to the device main body, the detection section is arranged on the device main body so as to be covered by the pressed surface, and the width of the pressed surface is wider than the width of the detection section and the hole.

[0008] In the following embodiment, a printing device is used as an example of an electronic device and will be described with reference to the drawings. In each of the following figures, XYZ axes, which are mutually orthogonal coordinate axes, are added as necessary, and the direction indicated by each arrow is the + direction, and the direction opposite to the + direction is the - direction. The +Z direction is sometimes referred to as upward, and the -Z direction is referred to as downward. In each of the following figures, the size of each component is made different from the actual size for the sake of convenience.

[0009] 1. First embodiment As shown in Fig. 1, the printing device 1 according to this embodiment includes a device body 10 and a door unit 16. The door unit 16 includes a top panel unit 64, a front panel unit 65, and a lower cover unit 61. Fig. 1 shows the printing device 1 with the door unit 16 closed.

[0010] The device body 10 has a shape in which two cubes with different heights in the Z direction are connected in the direction along the X axis. The device body 10 includes a front surface 9, a top surface 11, a back surface 7, and side surfaces 6 and 8. In the device body 10, the front surface 9 is a surface facing forward, the top surface 11 is a surface facing upward, the back surface 7 is a surface facing backward, the side surface 6 is a surface facing in the -X direction, and the side surface 8 is a surface facing in the +X direction. The device body 10 is a housing formed by combining panel-like members and the like that constitute these surfaces. Each member described later is housed inside the housing.

[0011] The top surface 11 includes a top surface portion 17 and a top surface panel portion 64 of the door portion 16, and a top surface portion 13. In the device body 10, the top surface portion 13 is disposed in the +X direction, and the top surface portion 17 and the top surface panel portion 64 are disposed in the -X direction of the top surface portion 13. The top surface portion 17 is adjacent to the top surface panel portion 64 in the direction along the Y axis, and is disposed in the -Y direction of the top surface panel portion 64.

[0012] In a plan view from above, the top surface portion 13, the top surface portion 17, and the top surface panel portion 64 are each substantially rectangular. The top surface portion 13, the top surface portion 17, and the top surface panel portion 64 are disposed along the XY plane. In the direction along the Z axis, the top surface portion 13, the top surface portion 17, and the top surface panel portion 64 have different heights. The top surface portion 17 and the top surface panel portion 64 have substantially the same height. The top surface portion 13 protrudes upwards beyond the top surface portion 17 and the top surface panel portion 64.

[0013] When the door portion 16 is closed, the front panel portion 65 and the lower cover portion 61 form the area in the −X direction of the front surface 9 , and the top panel portion 64 forms the area in front of the top surface portion 17 .

[0014] An operation panel 12 is provided on the front surface 9. The operation panel 12 is disposed in an area corresponding to the top surface 13 of the front surface 9 in a plan view from the +Y direction, more specifically, in the +X direction and above. Although not shown in the figure, the operation panel 12 includes a display that functions as a display unit that displays predetermined information, and operators such as operation buttons. Various operations of the printing device 1 can be controlled via the operation panel 12. The operation panel 12 may be a touch panel type display device.

[0015] The printing device 1 includes a printing unit 22. The printing unit 22 is located inside the device body 10 and below the top surface unit 13. The printing unit 22 includes a line-shaped inkjet head. The printing device 1 is an inkjet printer. In the printing device 1, ink is ejected from the inkjet head and deposited on a printing medium, thereby printing characters and images on the printing medium.

[0016] The top surface unit 13 includes a cover unit. The cover unit includes an area in the +Y direction of the top surface unit 13. By opening the cover unit, it is possible to perform maintenance work or adjustments on the printing unit 22 and the like.

[0017] 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.

[0018] Examples of continuous sheets include roll paper that is stored in the printer 1 in a rolled state, and fanfold paper that is supplied to the printer 1 from outside the printer 1 in a folded state. Examples of roll paper include plain paper or fine paper wound into a roll, as well as label paper in which standard-sized labels with adhesive on the backing are arranged on a release paper mount and wound into a roll. In this embodiment, a roll of label paper 100 is used as the printing medium. The printer 1 is a label printer.

[0019] The label paper 100 is disposed inside the device main body 10, below the top panel section 64. In the label paper 100, a label of a predetermined size with an adhesive on the backing is attached onto a backing paper on which a long release paper that can be peeled off from the adhesive is formed.

[0020] A plurality of labels are arranged at equal intervals in the longitudinal direction of the label paper 100. The printer 1 conveys the label paper 100 and prints characters and images on the printing surface of each label of the label paper 100.

[0021] As shown in Fig. 2, a paper discharge outlet 14 is provided on the side surface 8. The paper discharge outlet 14 is a slit that allows the label paper 100 to pass through. The printed label paper 100 is discharged from inside the printer 1 to the outside through the paper discharge outlet 14. In the printer 1, no operation unit, display unit, etc. are provided on the side surface 8 where the paper discharge outlet 14 is located.

[0022] As shown in Fig. 3, in the printing device 1, the door section 16 can be opened. The door section 16 is supported by the device body 10 so as to be openable and closable, and rotates about a connecting section 122 provided at approximately the center in the direction along the Y axis as a fulcrum. This allows the door section 16 to be opened and closed in the device body 10. In the following explanation, the state in which the door section 16 is fully open is also referred to as the open door state, and the state in which the door section 16 is fully closed is also referred to as the closed door state. Fig. 3 shows the open door state, and the above-mentioned Figs. 1 and 2 show the closed door state.

[0023] A storage section 20 that stores label paper 100 is provided inside the door section 16. The storage section 20 is located in an area closer to the side surface 6 when viewed from the +Y direction. In the printing device 1, opening the door section 16 exposes the storage section 20, making it possible to attach and remove the label paper 100. Opening the door section 16 also exposes components such as the roll shaft 26, paper guide unit 30, lower guide member 32, and paper pressing member 34, making it possible to adjust and perform maintenance on the above components related to the transport of the label paper 100. The functions of these components will be described later.

[0024] 4, the printing device 1 includes the above-mentioned storage unit 20, a printing unit 22 that prints on label paper 100, and a transport unit 24 that transports the label paper 100 from the storage unit 20 to the printing unit 22. In the printing device 1, the storage unit 20 is provided in the -X direction, and the printing unit 22 is provided in the +X direction of the storage unit 20. The transport unit 24 is provided below the printing unit 22.

[0025] The storage section 20 includes a roll shaft 26 on which the label paper 100 is attached. The roll shaft 26 is a rod-shaped member supported so as to be rotatable in the circumferential direction. The label paper 100 is stored in the storage section 20 with the roll shaft 26 inserted through the center of the roll. The roll shaft 26 may be connected to a drive device such as a motor, and may rotate in conjunction with the drive device. In the printing device 1, the label paper 100 also rotates as the roll shaft 26 rotates.

[0026] The printer 1 has a transport path R. Along the transport path R, one end of the label paper 100 attached to a roll shaft 26 is pulled out, printed, and then transported to the paper discharge outlet 14.

[0027] 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 columnar, with a curved surface in the circumferential direction, extending in the direction along the Y axis. 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 is transported in the +X direction.

[0028] A paper guide unit 30 is provided on the +X direction of the tension lever 28. The paper guide unit 30 guides the label paper 100 in the +X direction and prevents skewing and conveyance deviation of the label paper 100. 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 located on the upper surface side of the label paper 100.

[0029] The lower guide member 32 has a flat surface 33 extending along the X-axis. The flat surface 33 has a width dimension, in the direction along the Y-axis, 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.

[0030] 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.

[0031] 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.

[0032] 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 member for the label paper 100.

[0033] In the +X direction of the paper guiding unit 30, there is provided a printing unit 22 that prints on the label paper 100. The printing unit 22 includes a platen 40 and an inkjet head 42. The inkjet head 42 ejects ink of four colors, for example, cyan, magenta, yellow, and black, and deposits the ink on the printing surface of the label paper 100.

[0034] The inkjet head 42 includes a nozzle portion 41 that ejects black ink, a nozzle portion 43 that ejects cyan ink, a nozzle portion 45 that ejects magenta ink, and a nozzle portion 47 that ejects yellow ink. Each of the nozzle portions 41, 43, 45, and 47 has a nozzle row (not shown) that is made up of a plurality of nozzles that eject ink. The nozzle rows are aligned in a row in the width direction of the label paper 100.

[0035] In the nozzle sections 41, 43, 45, and 47, the nozzles are arranged in a direction intersecting the transport direction F, for example, 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 inkjet head 42 functions as an image forming section.

[0036] As described above, the inkjet head 42 is a line type inkjet head, and therefore does not scan in the width direction of the label paper 100. Each nozzle row of the nozzle units 41, 43, 45, and 47 is arranged at least as wide as the printable range of the label paper 100 or wider. In the printer 1, the printable range corresponds to the printing surface of the label paper 100. Note that, in the printer 1, a configuration in which the nozzle units 41, 43, 45, and 47 are arranged in this order along the transport direction F of the label paper 100 has been exemplified, but this is not limiting.

[0037] 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 inkjet head 42. The nozzle portions 41, 43, 45, and 47 and the platen 40 are arranged with a gap therebetween, which is a so-called platen gap.

[0038] 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.

[0039] The transport section 24 includes a cylindrical transport roller 50. The transport roller 50 extends in a direction whose longitudinal direction intersects with the transport direction F, and is supported so as to be freely rotatable in the circumferential direction. The transport roller 50 is disposed between the +X direction end of the paper guiding unit 30 and the -X direction end of the platen 40 in the transport direction F. The transport roller 50 is disposed near the +X direction end of the flat surface 33 of the lower guide member 32.

[0040] A driven wheel (not shown) is provided at one end of the transport roller 50. The transport motor 52 has a drive shaft (not shown). A transmission belt 51 is stretched between the driven wheel and the drive shaft. The transport roller 50 and the transport motor 52 are connected via the transmission belt 51. The transport motor 52 is a drive device that drives the transport roller 50 to rotate. The transport motor 52 and the transmission belt 51 are provided below the platen 40.

[0041] 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. Each of the plurality of driven rollers 54 is arranged rotatably along the longitudinal direction of the transport roller 50. Each driven roller 54 is biased so that the peripheral surface comes into contact with 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 arranged on the lower guide member 32 side, and the driven roller 54 is arranged on the paper pressing member 34 side.

[0042] The transport rollers 50 may be disposed on the lower guide member 32 side, in other words, on the platen 40 side. The transport unit 24 may include a transport belt that can move on the upper surface of the platen 40, instead of the transport rollers 50.

[0043] In the conveying section 24, the conveying roller 50 is rotated via the transmission belt 51 by the drive of the conveying motor 52, and the driven roller 54 is rotated accordingly. When the label paper 100 is loaded between the lower guide member 32 and the paper pressing member 34, it is sandwiched between the conveying roller 50 and the driven roller 54, and is conveyed to the printing section 22 by the rotation of the conveying roller 50.

[0044] The label paper 100 is placed on the flat surface 33 and sent out from the paper guiding unit 30, and is inserted and sandwiched between the transport roller 50 and the driven roller 54. In this state, the transport roller 50 rotates, transporting the label paper 100 to the printing section 22. In the printing device 1, the transport roller 50 and the driven roller 54 form a transport roller pair.

[0045] 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.

[0046] 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 along the Z axis with a distance sufficient 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 along the thickness direction of the label paper 100. The light-emitting unit 72 and the light-receiving unit 74 are positioned at approximately the same position in the direction along the X axis.

[0047] The label detector 70 may be disposed downstream of the transport rollers 50 and upstream of the inkjet head 42. 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 inkjet head 42 side.

[0048] In the label detector 70, the light-emitting unit 72 and the light-receiving unit 74 are disposed at a position where the light-receiving unit 74 can receive the light emitted from the light-emitting unit 72 at a predetermined signal intensity. 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 paper 100 are all different. Therefore, the label detector 70 is able to 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.

[0049] A cutter unit 99 is disposed downstream of the inkjet head 42 in the conveying direction F, specifically in the +X direction of the inkjet head 42. The cutter unit 99 includes a fixed blade 112 and a movable blade 114 disposed on either side of the conveying path R. The movable blade 114 is connected, for example via a gear, to a drive device such as a motor that drives the cutter. In the cutter unit 99, the movable blade 114 moves toward the fixed blade 112 when driven by the motor, and cuts the label paper 100.

[0050] The cutter unit 99 may leave a portion of the label paper 100 uncut in the width direction, or may completely cut the label paper 100. The printed label paper 100 is cut to a predetermined length by the cutter unit 99 and discharged from the paper discharge port 14. The cutter unit 99 may be separate from the printing device 1 and may be disposed, for example, detachably in the +X direction of the printing device 1.

[0051] The printer 1 includes a control board 18. The control board 18 comprehensively controls the operation of each component of the printer 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 temporarily stores data related to the firmware executed by the CPU, and the like.

[0052] The control board 18 may also include other peripheral circuits, and may also include a storage unit capable of non-volatilely storing various programs and data, such as control programs and data related to these control programs.

[0053] The control board 18 detects operations on the printing device 1 and the transport amount of the label paper 100. The control board 18 controls the driving devices equipped in the printing device 1, such as the transport motor 52. The control board 18 supplies voltage to the pump that supplies ink from an ink tank (not shown) in the inkjet head 42 and the piezoelectric elements of the nozzle portions 41, 43, 45, and 47 of the inkjet head 42 to operate them.

[0054] The control board 18 is formed so as to be able to activate the light emitting section 72 and the light receiving section 74, and to be able to acquire the detection value of the label detector 70. The label detector 70, together with the control board 18, functions as a detection means.

[0055] The control board 18 is also electrically connected to the detection unit 150, which will be described later. The detection unit 150 detects the open / closed state of the door unit 16, and transmits information about the open / closed state of the door unit 16 to the control board 18. For example, when the door unit 16 is not in a closed state, the control board 18 performs control to stop part or all of the driving of the conveying unit 24 and the like. The detection unit 150 is an example of a detection unit of the present invention.

[0056] 5, when the door section 16 is opened from the closed state, the end of the top panel section 64 in the +Y direction rises upward relative to the top section 17. At the same time, the front panel section 65 and the lower cover section 61 bend at the boundary along the X-axis. From this state, the top panel section 64 and the front panel section 65 rise further, and the angle of bending of the boundary increases, resulting in an open door state.

[0057] 6, the printing device 1 includes a pressing unit 110, a deformation unit 130, and a detection unit 150. A hole 120 is formed in the side surface 6 of the device body 10 into which the pressing unit 110 is inserted when the door is in the closed state.

[0058] The pressing portion 110 is disposed on the top panel portion 64 of the door portion 16. The pressing portion 110 is provided so as to protrude from a position corresponding to the hole 120.

[0059] The deformation portion 130 and the detection portion 150 are disposed inside the device body 10. The deformation portion 130 and the detection portion 150 come into contact with the pressing portion 110 inserted from the hole 120 when the door is in the closed state.

[0060] 7, the side surface 6 includes an exterior panel 6P. The exterior panel 6P is a substantially plate-shaped member whose main surface is along the YZ plane. The main surface of the exterior panel 6P facing the -X direction constitutes a part of the side surface 6. The exterior panel 6P is formed of a resin such as ABS (acrylonitrile-butadiene-styrene copolymer).

[0061] The hole 120 is provided at a position facing the +Y direction above the exterior panel 6P. The hole 120 is a long and thin slit along the Z axis.

[0062] As shown in Fig. 8, the device body 10 has a frame member 10F that constitutes a part of the device body 10. Here, in Fig. 8, with respect to the exterior panel 6P, illustration of only a part of the exterior panel 6P is omitted.

[0063] The frame member 10F is, for example, a metal member formed by sheet metal processing. The deformation section 130 and the detection section 150 are attached to the frame member 10F.

[0064] 9, the deformation portion 130 and the detection portion 150 are disposed relatively close in the -Y direction to the hole 120. The deformation portion 130 and the detection portion 150 are attached to an area along the YZ plane of the frame member 10F.

[0065] When viewed from the -Z direction, the deformation portion 130 surrounds the periphery of the detection portion 150. Fig. 9 shows a state in which the pressing portion 110 is not inserted into the hole 120, that is, a state in which the door is not in a closed state.

[0066] In the direction along the X-axis, the position of the hole 120 corresponds to a region including the ends of the deformation unit 130 and the detection unit 150 in the -X direction. Therefore, when the pressing unit 110 is inserted from the +Y direction through the hole 120, the pressing unit 110 comes into contact with the above-mentioned region. In the direction along the Z-axis, the width of the deformation unit 130 is wider than the width of the hole 120.

[0067] As shown in Fig. 10, when the door unit 16 is closed from the open state, the +Y direction of the top panel unit 64 descends. Here, in Fig. 10 and Fig. 11 described below, similarly to Fig. 8, illustration of only a part of the exterior panel 6P is omitted.

[0068] In a side view from the -X direction, the top panel portion 64 moves counterclockwise around the connecting portion 122, which is the boundary between the top panel portion 64 and the top portion 17. As a result, the pressing portion 110 also moves counterclockwise. At this time, since the pressing portion 110 is located relatively close to the connecting portion 122, it moves in approximately the -Y direction relative to the deformation portion 130 and the detection portion 150.

[0069] 11, in the closed state, the pressing portion 110 comes into contact with the deformation portion 130 and the detection portion 150. In detail, the detection portion 150 comes into indirect contact with the pressing portion 110 via the deformation portion 130. The deformation portion 130 is pressed in the approximately -Y direction by the pressing portion 110 and is deformed. The deformation of the deformation portion 130 will be described later.

[0070] As shown in Fig. 12, in the closed door state, the pressing portion 110 is inserted into the inside of the exterior panel 6P through the hole 120 of the exterior panel 6P. In the direction along the Y axis, the deformation portion 130 and the detection portion 150 are disposed relatively close to the hole 120. The moving direction of the pressing portion 110 when the pressing portion 110 passes through the hole 120 is approximately the -Y direction. When the pressing portion 110 is inserted into the inside of the exterior panel 6P through the hole 120, the pressing portion 110 moves in approximately the -Y direction while pressing the deformation portion 130 and the detection portion 150 while coming into contact with them.

[0071] At this time, the deformation portion 130 is deformed, and the detection portion 150 is pressed by the pressing portion 110 via the deformation portion 130, so that the lever portion 151 described later is displaced. That is, when the door portion 16 is closed, the state shown in FIG. 9 changes to the state shown in FIG. 12.

[0072] As shown in Figures 13, 14 and 15, the detection unit 150 has a lever portion 151, a main body portion 153, protrusions 155A and 155B, and a displacement shaft 157. The detection unit 150 detects that the door portion 16 is in a closed state, i.e., in a closed door state. Note that Figures 13 to 15 show the detection unit 150 when it is not in a closed door state.

[0073] The main body 153 is a substantially rectangular parallelepiped housing. The main body 153 houses an urging member and a sensor (not shown) inside, and supports the lever 151 by a displacement shaft 157. Protrusions 155A and 155B that protrude in the +X direction are arranged on the +Z and -Z side surfaces of the main body 153. Although not shown, wiring that electrically connects the above-mentioned control board 18 and the above-mentioned sensor and the like is arranged in the main body 153.

[0074] Lever portion 151 protrudes from main body portion 153 in approximately the -X direction and is supported by main body portion 153. A portion of the +X direction area of ​​lever portion 151 enters inside main body portion 153. When viewed from the -Z direction, lever portion 151 is supported by main body portion 153 and moves back and forth in an arc shape with displacement axis 157 as the center of rotation. When changing from the open door state to the closed door state, lever portion 151 is pushed in approximately the -Y direction via deformation portion 130 and falls in the -Y direction. At this time, a portion of lever portion 151 contained within main body portion 153 is also displaced in the same manner.

[0075] The sensor in main body 153 detects the door being in the closed state by the displacement of a part of lever 151 contained therein. As detection unit 150, in addition to the lever type, for example, a known sensor such as a cylinder type that presses down a protrusion such as a tactile switch or a push switch can be used.

[0076] The biasing member in main body 153 is attached to the part of lever 151 contained therein and to the housing of main body 153. The biasing member biases lever 151 so as to displace counterclockwise, i.e., to rise up, when viewed from the -Z direction. Examples of the biasing member include known biasing members such as a coil spring, a leaf spring, and rubber. The biasing force of the biasing member is smaller than the force with which detection unit 150 is pressed by pressing unit 110.

[0077] The protrusions 155A and 155B are fixing members for mounting the detection unit 150 to the frame member 10F of the device body 10. The protrusions 155A and 155B each have a claw-shaped tip, and this claw-shaped portion protrudes in the +X direction. The detection unit 150 is mounted by fitting the claw-shaped portion into the frame member 10F. When the detection unit 150 is mounted to the frame member 10F, the deformation unit 130 is also fixed to the frame member 10F at the same time.

[0078] As shown in FIG. 16, the deformation section 130 has a substantially rectangular planar shape before being incorporated into the device body 10. The deformation section 130 includes a flexible plate-like member. Specifically, the deformation section 130 is a plate-like member, and is a film made of synthetic resin. Synthetic resin can be procured relatively cheaply, and can be used to make the deformation section 130 easy to process and excellent in physical properties such as toughness. Examples of synthetic resins include polyester resins such as PET (polyethylene terephthalate), PC (polycarbonate), and PP (polypropylene).

[0079] The deforming portion 130 is preferably made of a material that is resistant to plastic deformation and has toughness. In addition to the above-mentioned synthetic resin, examples of the material for the deforming portion 130 include cellophane, paper, and film-like metal. The thickness of the deforming portion 130 is appropriately set according to the physical properties of the material. The deforming portion 130 is preferably flexible and highly elastic. The unfolded planar shape of the deforming portion 130 is not limited to a substantially rectangular shape.

[0080] The deformation portion 130 has two openings 131 and two openings 133. When the detection portion 150 is fixed to the frame member 10F, the corresponding protrusions 155A and 155B of the detection portion 150 are inserted into the openings 131 and 133. In this way, the deformation portion 130 is fixed to the frame member 10F together with the detection portion 150.

[0081] In the left-right direction in FIG. 16, which is the long side direction of the deformation section 130, two openings 131 are provided on one end, that is, the left, and two openings 133 are provided on the other end, that is, the right. The two openings 131 have a substantially rectangular planar shape and are arranged side by side in a direction along the Z axis. The two openings 133 also have a substantially rectangular planar shape and are arranged side by side in a direction along the Z axis. The openings 131 and 133 corresponding to each other in the left-right direction have the same planar shape. The two openings 131 have different planar shapes, and the two openings 133 also have different planar shapes. The openings 131 and 133 are not limited to holes, and may be notches.

[0082] The deformation unit 130 has folding lines 135a, 135b, and 135c. Each of the folding lines 135a, 135b, and 135c is a line segment that is folded when the plate-shaped deformation unit 130 is assembled to the device body 10 together with the detection unit 150. The folding lines 135a, 135b, and 135c are each arranged along the Z axis from the left to the right in this order.

[0083] The deformation portion 130 has a pressed surface 137. The pressed surface 137 includes an area that is pressed by the pressing portion 110 when the door portion 16 is closed in the device body 10. The pressed surface 137 has a substantially rectangular shape, and is provided between the folding lines 135a and 135b.

[0084] As shown in Fig. 17, the deformation unit 130 is folded at folding lines 135a, 135b, and 135c before being assembled with the detection unit 150. The deformation unit 130 may be transported and stored in such a folded state. This reduces the number of steps required for assembly. The deformation unit 130 can be transported and stored in a stacked state whether in the unfolded state or the folded state, reducing the costs required for transportation and storage.

[0085] The folding along the folding lines 135a, 135b, and 135c may be performed using only physical force, or may be performed by applying force after softening the plate-like member by heating.

[0086] As shown in FIGS. 18, 19, and 20, when the deformation portion 130 and the detection portion 150 are assembled and fixed to the frame member 10F, the detection portion 150 is covered by the deformation portion 130 when viewed from the -Z direction.

[0087] In Figures 18 and 19, frame member 10F is indicated by a two-dot chain line, and is omitted in Figure 20. In Figure 18, during the process of closing door section 16, pressing section 110 is indicated by a two-dot chain line, and the moving direction of pressing section 110 is indicated by a hollow arrow. Figures 18 to 20 show a state in which door section 16 is not in a closed state, and pressing section 110 is not in contact with deformation section 130. The shape of deformation section 130 in this state is referred to as the open state shape.

[0088] In the deformation section 130, the two openings 131 at one end and the two openings 133 at the other end are overlapped, and the protrusions 155A, 155B are inserted into the overlapped openings 131, 133. The protrusions 155A, 155B, while still inserted into the openings 131, 133, further pass through openings (not shown) of the frame member 10F. Therefore, the protrusions 155A, 155B and one and the other ends of the deformation section 130 are fixed to the device body 10. The deformation section 130 and the detection section 150 are fixed to the device body 10 in this simple configuration.

[0089] The method of fixing the deformation portion 130 to the frame member 10F is not limited to the above-mentioned method, and may be a method using, for example, double-sided adhesive tape or screws.

[0090] The detection unit 150 is disposed on the frame member 10F of the device body 10 so as to be covered by the pressed surface 137. In detail, the deformation unit 130 is fixed to the frame member 10F of the device body 10 in a ring state in which one end and the other end of the plate-like member are overlapped to form a ring when viewed from the -Z direction. The detection unit 150 is disposed on the device body 10 so as to be located inside the ring. As a result, the detection unit 150 is disposed inside the ring of the deformation unit 130, and damage to the detection unit 150 is further suppressed.

[0091] In addition, when fixing the deformation portion 130 to the frame member 10F, the one end and the other end do not have to overlap each other when viewed from the +X direction.

[0092] In this embodiment, the openings 131, 133 corresponding to each other in the direction along the Z axis are overlapped with each other, but this is not limited to this. For example, the one end and the other end may not be overlapped with each other, and may be fixed to the frame member 10F at different positions so that the pressed surface 137 is curved. In addition, the deformation portion 130 is in a substantially ring state, but this is not limited to this. When viewed from the -Z direction, the deformation portion 130 may be arch-shaped or the like. In this case, the openings 131 and 133 are fixed at different positions from each other.

[0093] When the deformation portion 130 is in the open state shape, the lever portion 151 of the detection portion 150 and the inner surface of the deformation portion 130 are spaced apart.

[0094] 18, in the open state, the portion from fold line 135a to fold line 135b is curved when viewed from the -Z direction. In other words, pressed surface 137 is curved in a convex shape so as to face the approximately -Y direction, which is the traveling direction when pressing portion 110 passes through hole 120. This makes it easier for deformation portion 130 to be deformed by the pressure of pressing portion 110.

[0095] When viewed from the -Z direction, the section from fold line 135b to fold line 135c is approximately along the XZ plane. The section from fold line 135a to the one end and the section from fold line 135c to the other end are along the plane of the frame member 10F.

[0096] 19 , in the direction along the Z axis, the width of pressed surface 137, in other words the width of deforming portion 130, is wider than the width of detection portion 150. As described above, in the direction along the Z axis, the width of hole 120 is narrower than the width of deforming portion 130, and the width of pressed surface 137 is wider than the width of hole 120.

[0097] 21 and 22, in the closed door state, the pressing portion 110 presses the pressed surface 137 and the lever portion 151 of the detection portion 150 in the approximately -Y direction. The deformation portion 130 is pressed by the pressing portion 110 and deforms to a closed state shape. The closed state shape refers to the shape of the deformation portion 130 in the closed door state. Note that the pressing portion 110 is not shown in FIG. 22.

[0098] The deformation portion 130 can be deformed between an open state shape and a closed state shape according to the open / closed state of the door portion 16 by the action of the pressing portion 110. That is, the shape of the deformation portion 130 transitions between the open state shape and the closed state shape according to the presence or absence of contact of the pressing portion 110 with the deformation portion 130 and the degree of contact.

[0099] In the closed door state, the pressing part 110 moves the most in the -Y direction, and the lever part 151 of the detection part 150 is pressed in approximately the -Y direction by the pressing part 110 via the pressed surface 137. As a result, the lever part 151 falls in approximately the -Y direction and is displaced clockwise around the displacement axis 157 as the center of rotation when viewed from the -Z direction, and the sensor in the main body part 153 detects that the door part 16 is in the closed door state.

[0100] In the closed state of the deformation portion 130, the curvature of the pressed surface 137 is gentler when viewed from the -Z direction than in the open state. Also, the portion between the fold line 135b and the fold line 135c is bent and deformed. Even in the closed state, the portion between the fold line 135a and the one end and the portion between the fold line 135c and the other end are aligned along the plane of the frame member 10F.

[0101] When the deformable portion 130 is in a closed state shape formed by pressing the pressing portion 110 with the pressed surface 137 against the pressing portion 110, the deformable portion 130 is released from the pressure of the pressing portion 110 when the door portion 16 is opened. The deformable portion 130 is flexible and has a restoring force against deformation. When released from the pressure, the deformable portion 130 deforms to an open state shape by its own restoring force. The deformable portion 130 can repeatedly deform between an open state shape and a closed state shape.

[0102] Lever portion 151 of detection unit 150 is biased in a direction to rise by a biasing member in main body portion 153. Therefore, when released from the pressure of pressing portion 110, lever portion 151 also displaces counterclockwise around displacement axis 157 as a rotation center when viewed from the -Z direction, and deforms so as to rise approximately in the +Y direction.

[0103] In the above embodiment, the inkjet printing device 1 is exemplified as an electronic device, but the electronic device of the present invention is not limited to this. The electronic device of the present invention may be a printing device other than the inkjet type, such as a laser printer, a copier or a multifunction device thereof, a measuring instrument such as a scale, a measuring instrument, a computer, an audio device, or a video device.

[0104] According to this embodiment, the following effects can be obtained.

[0105] This can prevent damage to the detection unit 150. More specifically, the detection unit 150 is pressed by the pressing unit 110 via the pressed surface 137 of the deformation unit 130, and the width of the pressed surface 137 is wider than the width of the detection unit 150 and the hole 120. Therefore, even if an object simulating the pressing unit 110 is inserted into the hole 120 and an unintended external force is applied, the detection unit 150 is protected by the deformation unit 130. Therefore, it is possible to provide a printing device 1 that prevents damage to the detection unit 150.

[0106] Since the deformation section 130 covers the detection section 150, the detection section 150 is protected from static electricity generated by the user, liquid entering through the hole 120, etc. This makes it possible to prevent damage to the electrical circuits and components of the detection section 150. In addition, since the deformation section 130 has a relatively simple configuration, it is possible to suppress increases in costs such as material costs and assembly labor costs.

[0107] To fix the deformation section 130 and the detection section 150 to the frame member 10F, protrusions 155A and 155B of the detection section 150 are used. Furthermore, the protrusions 155A and 155B are fitted into the frame member 10F and fixed. This makes it possible to assemble with a simple configuration without requiring special parts for fixing.

[0108] Since a film is used as the deformation portion 130, it is possible to produce a plate-like member by cutting the film. Compared to manufacturing a three-dimensional shape by injection molding or the like, no complicated molds are required, and the product can be manufactured at low cost.

[0109] The deformation portion 130 deforms in such a way as to release the pressing force in the direction of the pressing portion 110. Therefore, even if the door portion 16 is violently closed, a strong impact is unlikely to be transmitted to the detection portion 150, and damage to the detection portion 150 can be suppressed.

[0110] 2. Second embodiment In this embodiment, a deformation unit 230 applicable to the printing device 1 of the above embodiment is illustrated. The deformation unit 230 of this embodiment has a different form from the deformation unit 130 of the above embodiment. In the following description, the same reference numerals are used for the same components as in the first embodiment, and duplicated descriptions are omitted.

[0111] As shown in Figures 23 and 24, when the deformation portion 230 and the detection portion 150 are assembled and fixed to the frame member 10F, the detection portion 150 is covered by the deformation portion 230 when viewed from the -Z direction and the +Y direction. Note that the frame member 10F is indicated by a two-dot chain line in Figures 23 and 24. In Figure 23, the pressing portion 110 when the door portion 16 is closed is indicated by a two-dot chain line, and the moving direction of the pressing portion 110 is indicated by a hollow arrow.

[0112] Although not shown in the figures, the deformation section 230 is a plate-like member. The planar shape of the unfolded deformation section 230 is a substantially isosceles trapezoid. When the deformation section 230 is fixed to the frame member 10F, the longer side of a pair of parallel opposite sides of the trapezoid is disposed in the -Y direction, and the shorter side is disposed in the +Y direction.

[0113] Deformation section 230 has two openings 231 near one leg of the trapezoid, which is one end, and two openings 233 near the other leg, which is the other end. The two openings 231 and the two openings 233 correspond to protrusions 155A and 155B of detection section 150.

[0114] In the deformation portion 230, the two openings 231 at one end and the two openings 233 at the other end are overlapped, and the protrusions 155A, 155B are inserted into the overlapped openings 231, 233. The protrusions 155A, 155B, while still inserted through the openings 231, 233, are then inserted into openings (not shown) of the frame member 10F. As a result, the protrusions 155A, 155B and one and the other ends of the deformation portion 230 are fixed to the device body 10.

[0115] The number of openings 231 and 233 may be one each, and the protrusion 155B may be inserted into the opening 231, and the protrusion 155A may be inserted into the opening 233, and fixed to the frame member 10F.

[0116] The detection unit 150 is disposed on the frame member 10F of the device body 10 so as to be covered by the pressed surface 237. In detail, the deformation unit 230 is fixed to the frame member 10F of the device body 10 in a ring state in which one end and the other end of the plate-like member are overlapped to form a ring when viewed from the -Y direction. The detection unit 150 is disposed on the device body 10 so as to be located inside the ring. As a result, the detection unit 150 is disposed inside the ring of the deformation unit 230, and damage to the detection unit 150 is further suppressed.

[0117] 23, when viewed from the -Z direction, the pressed surface 237 is inclined with respect to the approximately -Y direction which is the traveling direction when the pressing portion 110 passes through the hole 120. This makes it easier for the deformation portion 230 to deform when pressed by the pressing portion 110.

[0118] 24 , in the direction along the Z axis, the width of pressed surface 237, in other words the width of deforming portion 230, is wider than the width of detection portion 150. As described above, in the direction along the Z axis, the width of hole 120 is narrower than the width of deforming portion 230, and the width of pressed surface 237 is wider than the width of hole 120.

[0119] As shown in Fig. 25 and Fig. 26, in the closed door state, the pressing portion 110 presses the pressed surface 237 and the lever portion 151 of the detection portion 150 in the approximately -Y direction. The deformation portion 230 is deformed into a closed state shape by being pressed by the pressing portion 110. The closed state shape refers to the shape of the deformation portion 230 in the closed door state. Note that the pressing portion 110 is illustrated only in Fig. 25.

[0120] The deformation portion 230 can be deformed between an open state shape and a closed state shape according to the opening and closing state of the door portion 16 by the action of the pressing portion 110. That is, the shape transitions between the open state shape and the closed state shape according to the presence or absence of contact of the pressing portion 110 with the deformation portion 230 and the degree of contact.

[0121] When the deformation portion 230 is in the closed state, the inclination of the pressed surface 237 with respect to the Y axis is gentler when viewed from the -Z direction than when it is in the open state.

[0122] When the door part 16 is opened while the deformable part 230 is in a closed state shape formed by the pressing surface 237 being pressed by the pressing part 110, the deformable part 230 is released from the pressing of the pressing part 110. Since the deformable part 230 is flexible, it has a restoring force against deformation. The deformable part 230 is deformed to an open state shape by its own restoring force. The deformable part 230 can be repeatedly deformed between an open state shape and a closed state shape.

[0123] The deformation unit 230 is applicable to the various electronic switch components described above as the detection unit 150. The deformation unit 230 and the detection unit 150 are applicable to the electronic devices described above in addition to the printing device 1.

[0124] According to this embodiment, it is possible to obtain the same effects as those of the above embodiment. [Explanation of symbols]
