[0008] The present invention will now be briefly described. A solenoid device according to a first aspect comprises a solenoid having a plunger that displaces in a first direction in which it is retracted into a solenoid body and in a second direction in which it protrudes from the solenoid body, a frame on which the solenoid is mounted, and an abutment portion against which the plunger abuts when it moves in the second direction, wherein the solenoid body is attached to the frame via a first mounting portion, and the abutment portion is attached to the frame via a second mounting portion.

[0009] According to this aspect, since the abutment portion is attached to the frame via the second attachment portion, vibrations caused by an impact when the plunger abuts on the abutment portion are transmitted from the abutment portion to the frame via the second attachment portion. This makes it difficult for the frame to vibrate compared to a configuration in which the plunger directly abuts on the second attachment portion, and makes it possible to suppress noise caused by the vibration of the frame.

[0010] The second aspect is a dependent aspect of the first aspect, and is characterized in that the abutment portion has a first end which is an end on the side against which the plunger abuts, and a second end which is an end opposite to the first end and located in the second direction relative to the first end, and a slit which is deformable when the plunger abuts against the first end is provided at a position between the first end and the second end in the displacement direction of the plunger and closer to the first end.

[0011] According to this aspect, a slit that is deformable when the plunger abuts against the first end is provided between the first end and the second end and closer to the first end, so that a part of the abutment portion deforms, thereby further suppressing the impact when the plunger abuts against the abutment portion. As a result, vibrations caused by the impact are suppressed, and the generation of the noise can be further suppressed. In addition, the impact when the plunger abuts on the abutment portion can be suppressed by providing a cushioning material on the surface with which the plunger abuts, but in this case, there is a risk of the positioning accuracy of the plunger decreasing. However, by providing the slit between the first end and the second end, the original state is restored even if a part of the abutment portion is deformed, so that the positioning accuracy of the plunger can be easily ensured compared to a configuration in which the cushioning material is provided.

[0012] A third aspect is an aspect dependent on the second aspect, characterized in that the slit overlaps with a region obtained by extending a movement region of the plunger in the second direction. According to this aspect, since the slit overlaps with the region obtained by extending the movement region of the plunger in the second direction, the portion of the abutment part where the slit is formed is easily deformed, and the impact when the plunger abuts on the abutment part can be effectively suppressed. As a result, the vibration caused by the impact is effectively suppressed, and the generation of the noise can be more effectively suppressed.

[0013] A fourth aspect is an aspect dependent on the first aspect, and is characterized in that, in the displacement direction of the plunger, the frame is located in the first direction relative to the abutment portion, and the abutment portion has a first end which is an end on the side against which the plunger abuts, a second end which is an end opposite to the first end and located in the second direction relative to the first end, and a regulated surface which is a portion that engages with the second mounting portion and whose movement in the second direction is regulated, and the regulated surface is provided at a position between the first end and the second end in the movement direction of the plunger and closer to the second end.

[0014] When the plunger comes into contact with the contact portion, the contact portion tries to move in the second direction, but the movement in the second direction is restricted by the regulated surface. Therefore, vibration caused by the impact when the plunger comes into contact with the contact portion is transmitted to the second attachment portion via the regulated surface, and then to the frame. Here, in the displacement direction of the plunger, the frame is positioned in the first direction relative to the abutment portion, and therefore the further the regulated surface is positioned in the second direction, the more the distance between the regulated surface and the frame can be secured, and as a result, the vibration caused by the impact is further damped and the generation of noise can be further suppressed. In this embodiment, the regulated surface is provided between the first end and the second end in the moving direction of the plunger and closer to the second end, so that a sufficient distance can be secured between the regulated surface and the frame, thereby further attenuating the vibration caused by the impact and further suppressing the generation of the noise. Incidentally, this aspect is not limited to the first aspect, but may be subordinate to the second or third aspect.

[0015] A fifth aspect is an aspect dependent on the first aspect, and is characterized in that a vibration damping member that damps vibration is interposed between the abutment portion and the second attachment portion. According to the present aspect, since a vibration damping member that damps vibrations is interposed between the abutment portion and the second mounting portion, the vibrations caused by the impact are further damped, and the generation of the noise can be further suppressed. Incidentally, this aspect is not limited to the above-mentioned first aspect, and may be subordinate to any of the above-mentioned second to fourth aspects.

[0016] A sixth aspect is a dependent aspect of the fifth aspect, characterized in that the vibration damping member has a first surface that contacts the abutment portion and a second surface opposite the first surface that contacts the second mounting portion.

[0017] According to this aspect, the vibration damping member has a first surface that contacts the abutment portion and a second surface opposite the first surface that contacts the second mounting portion, thereby being able to damp vibration transmitted from the surface of the abutment portion with which the first surface contacts to the surface of the second mounting portion with which the second surface contacts. In addition, when vibrations are transmitted through the second mounting portion, the second surface is in contact with the second mounting portion, so that the vibrations transmitted through the second mounting portion can be attenuated. As a result, the generation of noise can be further suppressed.

[0018] A seventh aspect is a dependent aspect of the first aspect, characterized in that the abutment portion is provided on the second mounting portion with play in a direction intersecting the displacement direction of the plunger. According to this aspect, the abutment portion is provided on the second mounting portion with play in a direction intersecting the displacement direction of the plunger, thereby making it possible to suppress vibrations transmitted from the abutment portion to the second mounting portion, and thus to further suppress the generation of noise. Incidentally, this aspect is not limited to the above-mentioned first aspect, and may be subordinate to any of the above-mentioned second to sixth aspects.

[0019] The eighth aspect is a aspect dependent on the second aspect, and is characterized in that, in the displacement direction of the plunger, the frame is located in the first direction relative to the abutment portion, the abutment portion has a regulated surface which engages with the second mounting portion and is a portion whose movement in the second direction is regulated, and the regulated surface is provided at a position between the first end and the second end in the movement direction of the plunger and closer to the second end.

[0020] When the plunger comes into contact with the contact portion, the contact portion tries to move in the second direction, but the movement in the second direction is restricted by the regulated surface. Therefore, vibration caused by the impact when the plunger comes into contact with the contact portion is transmitted to the second attachment portion via the regulated surface, and then to the frame. Here, in the displacement direction of the plunger, the frame is positioned in the first direction relative to the abutment portion, and therefore the further the regulated surface is positioned in the second direction, the more the distance between the regulated surface and the frame can be secured, and as a result, the vibration caused by the impact is further damped and the generation of noise can be further suppressed. In this embodiment, the regulated surface is provided between the first end and the second end in the moving direction of the plunger and closer to the second end, so that a sufficient distance can be secured between the regulated surface and the frame, thereby further attenuating the vibration caused by the impact and further suppressing the generation of the noise.

[0021] A ninth aspect is a aspect dependent on the eighth aspect, and is characterized in that a vibration damping member that damps vibration is interposed between the abutment portion and the second attachment portion. According to the present aspect, since a vibration damping member that damps vibrations is interposed between the abutment portion and the second mounting portion, the vibrations caused by the impact are further damped, and the generation of the noise can be further suppressed.

[0022] The tenth aspect is a aspect dependent on the ninth aspect, and is characterized in that the first end, the vibration damping member, the regulated surface, and the second end are positioned in that order along the second direction. According to this aspect, since the vibration damping member is located between the first end and the regulated surface, in a configuration in which vibration is transmitted to the second attachment part via the regulated surface and then to the frame, it is possible to damp vibration from the regulated surface toward the frame, which results in further damping of vibration caused by the impact, and further suppression of the generation of the noise.

[0023] An eleventh aspect is a mode dependent on the second aspect, and is characterized in that a vibration damping member that damps vibration is interposed between the abutment portion and the second attachment portion. According to the present aspect, since a vibration damping member that damps vibrations is interposed between the abutment portion and the second mounting portion, the vibrations caused by the impact are further damped, and the generation of the noise can be further suppressed.

[0024] A twelfth aspect is an aspect dependent on the first aspect, characterized in that the first attachment portion and the second attachment portion are integral with each other. According to the present aspect, since the first mounting portion and the second mounting portion are integrated, the positional relationship between the solenoid body and the abutment portion is determined with greater precision than in a configuration in which the first mounting portion and the second mounting portion are separate, thereby improving the positional accuracy of the plunger when it is displaced in the second direction. Incidentally, this aspect is not limited to the above-mentioned first aspect, and may be subordinate to any of the above-mentioned second to eleventh aspects.

[0025] A media transport device according to a thirteenth aspect comprises a transport roller pair that nip and transport a medium, the transport roller pair having a first roller that contacts a first side of the medium and a second roller that contacts a second side of the medium opposite to the first side, and a gate unit that can be switched between a first state in which the medium transport path is blocked upstream in the medium transport direction of the nip position at which the medium is nipped by the transport roller pair, and a second state in which the medium transport path is opened, the gate unit being provided on a rotating member that is rotatable about a first rotating shaft that is the rotating shaft of the first roller, and the rotating member being driven by the solenoid device according to any of the first to twelfth aspects.

[0026] According to this aspect, the medium conveying device is capable of correcting skewed media by the gate portion, and the rotating member on which the gate portion is provided is driven by the solenoid device relating to any of the first to twelfth aspects, so that the medium conveying device can obtain the action effects of any of the first to twelfth aspects described above.

[0027] A recording device according to a fourteenth aspect includes a recording section that records on a medium, and the medium conveying device according to the thirteenth aspect. According to this aspect, in a recording device that records on a medium, the operational effects of any one of the above-mentioned first to twelfth aspects can be obtained.

[0028] The present invention will be specifically described below. The following describes an inkjet printer 1 that performs recording by ejecting ink, which is an example of a liquid, onto a medium, such as recording paper. In the following, the inkjet printer 1 will be abbreviated to printer 1. The printer 1 is an example of a recording device.

[0029] The XYZ coordinate system shown in each figure is an orthogonal coordinate system, with the Y axis direction being the direction that intersects with the medium transport direction, i.e., the width direction of the medium, and also the depth direction of the device. The Y axis direction is also the direction of the rotation axis of each roller, which will be described later. Within the Y axis direction, the +Y direction is the direction from the front of the device to the rear of the device, and the -Y direction is the direction from the rear of the device to the front of the device. The X-axis direction is the width direction of the device, with the +X direction being the left side and the -X direction being the right side as seen by the operator of the printer 1. The Z-axis direction is the vertical direction, or the height direction of the device, with the +Z direction being the upward direction and the -Z direction being the downward direction. In the following, the direction in which the medium is transported may be referred to as "downstream," and the opposite direction may be referred to as "upstream." In addition, the medium transport path is shown by a dashed line in Figure 1. In the printer 1, the medium is transported through the medium transport path shown by the dashed line.

[0030] The F-axis direction is the medium transport direction between a line head 46 (to be described later) and the transport belt 13, i.e., in the recording area, with the +F direction being the downstream transport direction and the opposite -F direction being the upstream transport direction. The V-axis direction is the movement direction of the head unit 45, with the +V direction being the direction in which the head unit 45 moves away from the transport belt 13 and the -V direction being the direction in which the head unit 45 moves towards the transport belt 13.

[0031] The printer 1 is equipped with a first media cassette 3 that stores media at the bottom of the device main body 2, and is further configured so that an expansion unit 6 can be connected to the bottom of the device main body 2. When the expansion unit 6 is connected, a second media cassette 4 and a third media cassette 5 are located below the first media cassette 3. The media sent out from each media cassette is transported inside the printer 1 along a media transport path indicated by a dashed line.

[0032] A pick roller that feeds the stored medium in the -X direction is provided for each medium cassette. Pick rollers 21, 22, and 23 are provided for the first medium cassette 3, the second medium cassette 4, and the third medium cassette 5, respectively. Further, a pair of feed rollers is provided for each medium cassette, which feeds the medium sent in the -X direction in an upward diagonal direction. Feed roller pairs 25, 26, and 27 are provided for the first medium cassette 3, the second medium cassette 4, and the third medium cassette 5, respectively. In the following, unless otherwise specified, a "roller pair" is defined as consisting of a drive roller driven by a motor (not shown) and a driven roller that rotates in contact with the drive roller.

[0033] The medium sent out from the third media cassette 5 is transported to the transport roller pair 35 by the transport roller pair 29, 28. The medium sent out from the second media cassette 4 is transported to the transport roller pair 35 by the transport roller pair 28. The medium is transported by the transport roller pair 35 to the transport roller pair 38 that constitutes the media transport device 50. Hereinafter, the section of the media transport path from the transport roller pair 35 to the transport roller pair 38 is referred to as the curved path T0. The curved path T0 is the section that curves the medium so that it is convex downward as shown in FIG. 1. The transport roller pair 35 is composed of a drive roller 36 driven by a motor (not shown) and a driven roller 37 that can rotate following the drive roller 36. The transport roller pair 38 is composed of a drive roller 39 driven by a motor (not shown) and a driven roller 40 that can rotate following the drive roller 36. The drive roller 39 is an example of a first roller that contacts the first surface of the medium, and the driven roller 40 is an example of a second roller that contacts the second surface of the medium.

[0034] The medium sent out from the first medium cassette 3 is sent to the transport roller pair 38 without passing through the transport roller pair 35. Reference symbol T4 denotes a medium transport path from the first medium cassette 3 to the transport roller pair 38, and hereinafter this is referred to as the upper cassette feed path T4. 1. Furthermore, a supply roller 19 and a separation roller 20 provided near the pair of transport rollers 35 are rollers that feed the medium from a supply tray not shown in FIG.

[0035] The medium receiving the feeding force from the transport roller pair 38 is sent to a recording position between the line head 46, which is an example of a recording unit, and the transport belt 13, that is, facing the line head 46. Note that hereinafter, the medium transport path from the transport roller pair 38 to the transport roller pair 30 is referred to as the transport path T1 during recording.

[0036] The line head 46 constitutes the head unit 45. The line head 46 performs recording by ejecting ink, which is an example of liquid, onto the surface of the medium. The line head 46 is an ink ejection head configured so that the nozzles that eject ink cover the entire area in the width direction of the medium, and is configured as an ink ejection head that can perform recording over the entire width of the medium without moving in the width direction of the medium. However, the ink ejection head is not limited to this, and may be a type that is mounted on a carriage and ejects ink while moving in the width direction of the medium.

[0037] The head unit 45 is provided so as to be able to advance and retreat with respect to the transport path T1 during recording, and is provided so as to be displaceable between a recording position shown by a solid line in Fig. 1 and a retracted position where it is retracted furthest from the transport belt 13, as shown by a two-dot chain line and reference symbol 45-1 in Fig. 1. When the head unit 45 is in the retracted position, maintenance of the line head 46 is performed by a maintenance means (not shown). In this embodiment, the displacement direction of the head unit 45 is the V-axis direction along the inclination of the discharge tray 8. The head unit 45 is located below the discharge tray 8 and upstream in the medium discharge direction, and displaces along the bottom surface of the discharge tray 8.

[0038] Reference numerals 12a, 12b, 12c, and 12d denote ink storage units that store ink. Ink to be ejected from the line head 46 is supplied from each ink storage unit to the line head 46 via a tube (not shown). Each ink storage unit is provided so as to be detachable. Reference numeral 11 denotes a waste liquid storage section that stores ink as waste liquid discharged from the line head 46 toward a flushing cap (not shown) for maintenance purposes.

[0039] The conveyor belt 13 is an endless belt that is wound around pulleys 14 and 15, and rotates when at least one of the pulleys 14 and 15 is driven by a motor (not shown). The medium is conveyed to a position facing the line head 46 while being attracted to the belt surface of the conveyor belt 13. The medium can be attracted to the conveyor belt 13 by a known attraction method such as an air suction method or an electrostatic attraction method.

[0040] Here, the transport path T1 during recording, which passes through a position facing the line head 46, is configured to transport the medium upward at an angle to the horizontal and vertical directions. This upward transport direction is a direction that includes a -X direction component and a +Z direction component in Figure 1, and this configuration makes it possible to reduce the horizontal dimension of the printer 1. In this embodiment, the recording transport path T1 is set at an inclination angle in the range of 65° to 85° with respect to the horizontal direction, and more specifically, is set at an inclination angle of approximately 75°.

[0041] The medium on which recording has been performed by the line head 46 is further conveyed upward by a pair of conveying rollers 30 positioned downstream of the conveying belt 13 . A flap 41 is provided downstream of the transport roller pair 30, and the transport direction of the medium is switched by this flap 41. When the medium is to be discharged as is, the transport path of the medium is switched by the flap 41 to face the upper transport roller pair 31, and the medium is discharged by the transport roller pair 31 toward the discharge tray 8.

[0042] When recording on both sides of the medium, the transport direction of the medium is directed to branch position K1 by flap 41. The medium then passes through branch position K1 and enters switchback path T2. In this embodiment, switchback path T2 is the medium transport path above branch position K1. A pair of transport rollers 32A and 32B is provided on switchback path T2. The medium that enters switchback path T2 is transported upward by the pair of transport rollers 32A and 32B, and when the bottom edge of the medium passes branch position K1, the rotation direction of the pair of transport rollers 32A and 32B is switched, thereby transporting the medium downward.

[0043] The switchback path T2 is connected to a reversing path T3. In this embodiment, the reversing path T3 is a path section that runs from the branch position K1 through the transport roller pairs 33 and 34 to the transport roller pair 38. Therefore, the reversing path T3 includes the curved path T0. The medium transported downward from branch position K1 receives a feeding force from transport roller pairs 33 and 34, reaches transport roller pair 35, and is sent by transport roller pair 35 toward transport roller pair 38. By reversing path T3, the surface of the medium that was facing downward, i.e., the surface opposite to the already recorded surface, faces upward. Incidentally, reference numeral 42 denotes a flap, which is provided so as to be rotatable about a rotation axis (not shown). The flap 42 is normally in a lowered position, and guides the medium traveling along the reversal path T3 to the transport roller pair 35. In contrast, the medium sent out from the second media cassette 4 or the third media cassette 5 below the transport roller pair 35 reaches the transport roller pair 35 by pushing up the flap 42.

[0044] Then, the medium is sent through the reversing path T3 to a position facing the line head 46, and the surface opposite to the surface that initially faced the line head 46 faces the line head 46. This makes it possible for the line head 46 to record on both sides of the medium.

[0045] 2 onward, a detailed description will be given of the medium transport device 50 including the transport roller pair 38. The medium transport device 50 includes the transport roller pair 38, a gate portion 35a, and a solenoid device 60 which will be described later. 2, the driving roller 39 constituting the pair of transport rollers 38 is provided on a first rotating shaft 39a. In this embodiment, the driving roller 39 is a toothed roller having a plurality of teeth (not shown) on its outer periphery.

[0046] The first rotating shaft 39a is provided with a rotating member 53. The rotating member 53 is provided rotatably with respect to the first rotating shaft 39a, and a gate portion 53a is provided on the rotating member 53. The rotating member 53 is rotationally driven by a solenoid device 60, which will be described later. In this embodiment, the gate portion 53a is provided integrally with the rotating member 53. However, the gate portion 53a may be provided on the rotating member 53 as a separate member. When the medium reaches the conveying roller pair 38 through the curved path T0 or the upper cassette feed path T4, its leading edge Pf (see Figure 5) abuts against the gate portion 53a, a curve is formed upstream of the leading edge Pf, so that the leading edge Pf follows the gate portion 53a and the skew is corrected.

[0047] As the rotating member 53 rotates, the gate portion 53a can be switched between a first state (the state in FIGS. 2 and 3) in which the gate portion 53a blocks the curved path T0 or the upper cassette feed path T4 upstream in the medium transport direction from the nip position where the medium is nipped by the transport roller pair 38, and a second state (the state in FIG. 4) in which the gate portion 53a opens the curved path T0 or the upper cassette feed path T4. When skew correction of the medium is to be performed, the gate portion 53a is set to the first state, and when skew correction is completed, the gate portion 53a is set to the second state. Furthermore, in the first state of gate portion 53a, it is sufficient that the leading edge of the medium abuts gate portion 53a upstream of the nip position of the medium by the transport roller pair 38. For example, in Figure 3, nip position Np of the medium by the transport roller pair 38 may overlap with gate portion 53a. The state switching of the gate portion 53a is controlled by a control portion (not shown) driving a solenoid 61 (see FIG. 8) which will be described later.

[0048] As shown in Figs. 5 and 6, a plurality of rotating members 53 are provided at a predetermined interval along the rotation axis direction of the first rotating shaft 39a. In Figs. 5 and 6, the reference character CL indicates the center position in the medium width direction, and the rotating members 53 are arranged so as to have a bilaterally symmetrical structure with respect to the center position CL. In this embodiment, three rotating members 53 are arranged on each of the left and right sides of the center position CL. Note that, hereinafter, when the term "rotation axis direction" is used, it means the Y-axis direction. In this embodiment, the Y-axis direction is the rotation axis direction of the first rotating shaft 39a which is the rotation axis of the driving roller 39, the rotation axis direction of the second rotating shaft 40a (see Figs. 2 to 4) which is the rotation axis of the driven roller 40, and also the medium width direction. The multiple rotating members 53 are attached to a connecting frame 55 so that all of the rotating members 53 rotate simultaneously.

[0049] 6, in this embodiment, the rotating members 53 include rotating members 53A located at both ends in the rotation axis direction, and rotating member 53B located between the two rotating members 53A. The rotating member 53A has a region facing the outer circumferential surface of the first rotating shaft 39a that is 180° or more in the circumferential direction, and has a shape that allows the first rotating shaft 39a to be inserted therethrough. The inner diameter of the rotating member 53A is approximately equal to or slightly larger than the outer diameter of the first rotating shaft 39a, so that the rotating member 53A rotates while contacting the outer circumferential surface of the first rotating shaft 39a. In contrast, the region of the rotating member 53B that faces the outer circumferential surface of the first rotating shaft 39a is less than 180° along the circumferential direction, and the inner diameter of the rotating member 53B is larger than the inner diameter of the rotating member 53A. As a result, the rotating member 53B rotates around the first rotating shaft 39a without contacting the outer circumferential surface of the first rotating shaft 39a, or even if it does contact, the contact is limited to a slight contact.

[0050] With the above configuration, when the rotating members 53A and 53B rotate integrally via the connecting frame 55, the rotating members 53A located at both ends in the rotational axis direction come into contact with the outer circumferential surface of the first rotating shaft 39a. If all the rotating members 53 were rotating members 53A, there is a risk that the members will be gouged during rotation due to dimensional errors, preventing smooth rotation. However, since the rotating members 53A located at both ends in the rotational axis direction are designed to come into contact with the outer circumferential surface of the first rotating shaft 39a as described above, all the rotating members 53 can rotate smoothly. However, the position of gate portion 53a in the medium transport direction is designed to be the same for rotating member 53A and rotating member 53B. In this specification, when there is no need to distinguish between the rotating member 53A and the rotating member 53B, they will be collectively referred to as the rotating member 53.

[0051] Mounting members 56 are provided on both ends of the connecting frame 55 in the rotation axis direction, and a grounding member 54 is provided on the mounting members 56. The grounding member 54 has a ring shape through which the first rotating shaft 39a is inserted, is made of sintered metal, and is electrically connected to a grounding part (not shown) to release static electricity from the first rotating shaft 39a to the outside. However, the inner diameter of the grounding member 54 is set with a margin relative to the outer diameter of the first rotating shaft 39a, and when the rotating members 53A and 53B and the grounding member 54 rotate together, the main part that comes into contact with the first rotating shaft 39a is the rotating member 53A.

[0052] A pressed portion 56a is formed on the mounting member 56 in the -Y direction so as to protrude in the -Y direction. Here, a rotating cam 64 is provided in the region of the -Y direction end of the first rotating shaft 39a as shown in Fig. 7. When the pressed portion 56a is pressed in the direction of the arrow Bp by the rotating cam 64, the rotating member 53 rotates in the clockwise direction in Fig. 3 from the state in Fig. 3, and the gate portion 53a switches from the first state to the second state. Note that a pressing force in the counterclockwise direction in Fig. 3 is applied to the connecting frame 55 by a pressing member (not shown), for example a torsion spring, and when the pressing of the pressed portion 56a by the rotating cam 64 is released, the rotating member 53 rotates in the counterclockwise direction in Fig. 4 from the state in Fig. 4, and the gate portion 53a switches from the second state to the first state.

[0053] The rotating cam 64 is provided rotatably about a rotating shaft 65 as shown in Figs. 7, 8 and 9. In this embodiment, the rotating shaft 65 is aligned along the Z-axis direction. The rotating cam 64 has a first engaging portion 64a and a second engaging portion 64b extending from the rotating shaft 65. The second engaging portion 64b is a portion that presses the pressed portion 56a, and the first engaging portion 64a is a portion that engages with the engaging member 63. 7 and 8, the overall shape of the engagement member 63 is hidden, but it is attached to the plunger 62 of the solenoid 61, and is displaced in the Y-axis direction when the plunger 62 of the solenoid 61 is displaced in the Y-axis direction, causing the rotating cam 64 to rotate about the rotation shaft 65. The overall shape of the engagement member 63 is shown in Figure 16. The rotating shaft 65 is provided on a mounting frame 67 , and the solenoid 61 is also attached to the mounting frame 67 .

[0054] The solenoid device 60 including the solenoid 61 will be further described below. There are multiple embodiments of the solenoid device, and each embodiment is distinguished by adding a capital alphabet to the reference numeral 60. When it is not necessary to distinguish between the embodiments, they will be collectively referred to as the solenoid device 60. The solenoid device 60 includes a frame 59, a solenoid 61, a mounting frame 67, and an abutment portion 68. There are multiple embodiments of the abutment portion, and each embodiment is distinguished by adding a capital alphabet to the reference numeral 68. When it is not necessary to distinguish between the embodiments, the reference numeral 68 is used to collectively refer to the abutment portion 68. The frame 59 forms a base of the solenoid device 60, and forms a frame surface along the XZ plane. In this embodiment, the frame 59 is formed of a metal plate.

[0055] The solenoid 61 according to this embodiment includes a plunger 62 that is displaceable along the Y-axis direction. The solenoid 61 is configured so that the plunger 62 is displaced by switching the direction of current flow, with the +Y direction being the return direction of the plunger 62 and the -Y direction being the attraction direction of the plunger 62. The control unit (not shown) of the printer 1 drives the solenoid 61 by switching the direction of current flow to the solenoid 61, thereby switching the gate unit 53a described above between the first state and the second state.

[0056] The solenoid 61 is attached to the frame 59 via a mounting frame 67. The mounting frame 67 has a first mounting portion 67A, which is a portion where the main body 61a of the solenoid 61 is attached, and a second mounting portion 67B, which is a portion where the abutment portion 68 is attached. In this embodiment, the first mounting portion 67A and the second mounting portion 67B are provided integrally, so that the positional relationship between the main body 61a of the solenoid 61 and the abutment portion 68 is determined with higher accuracy than in a configuration in which the first mounting portion 67A and the second mounting portion 67B are separate bodies, and thus the positional accuracy of the plunger 62 when the plunger 62 is displaced in the +Y direction is improved. In this embodiment, the first attachment portion 67A and the second attachment portion 67B are integrally provided, but the first attachment portion 67A and the second attachment portion 67B may be separate bodies. In this embodiment, the mounting frame 67 is formed from a metal plate.

[0057] As shown in Figures 8 to 10, the first mounting portion 67A is shaped to sandwich the main body 61a of the solenoid 61 in the X-axis direction, and in this embodiment, the main body 61a is fixed to the first mounting portion 67A by three solenoid fixing screws 71. The second mounting portion 67B has a shape capable of supporting the contact portion 68 on the XY plane, and the contact portion 68 is fixed to the second mounting portion 67B by one contact portion fixing screw 69. The contact portion fixing screw 69 passes through a screw insertion hole 68j formed in the contact portion 68A in Fig. 10 and fits into a screw hole formed in the second mounting portion 67B.

[0058] The mounting frame 67 is integrally provided with frame fixing portions 67c and 67d that form surfaces parallel to the XZ plane, and the frame fixing portions 67c and 67d are fixed to the frame 59 by frame fixing screws 72, respectively. In Fig. 10, reference numerals 67f-1 and 67f-2 denote screw insertion holes for inserting the frame fixing screws 72. The screw insertion hole 67f-1 is substantially circular, and the screw insertion hole 67f-2 is formed as an elongated hole that is long in the X-axis direction, which can absorb dimensional tolerances. In Fig. 11, reference numeral 59b denotes a screw hole into which the frame fixing screws 72 fit.

[0059] As shown in Fig. 11, two positioning bosses 59c are formed on the frame 59. As shown in Fig. 10, the mounting frame 67 has a positioning hole 67g-1 formed in the frame fixing portion 67c, and a positioning hole 67g-2 formed in the frame fixing portion 67d. One of the two positioning bosses 59c of the frame 59 fits into the positioning hole 67g-1 of the frame fixing portion 67c, and the other fits into the positioning hole 67g-2 of the frame fixing portion 67d. The positioning hole 67g-2 has a substantially circular shape, and the positioning hole 67g-1 is formed as an oblong hole that is long in the X-axis direction, which makes it possible to absorb dimensional tolerances. In FIG. 11, reference numeral 59a denotes an opening for passing a main body 61a of a solenoid 61 therethrough.

[0060] As shown in FIG. 10, the second mounting portion 67B is formed with two positioning holes 67e. The solenoid device 60A according to the first embodiment has a contact portion 68A. Two regulated portions 68b are formed in a hook shape on the contact portion 68A as shown in Fig. 12. The regulated portions 68b of the contact portion 68A can enter the positioning holes 67e of the second attachment portion 67B. 12, reference numeral 68c denotes a part of the surface of regulated portion 68b, which is a regulated surface. When regulated surface 68c abuts against the edge of positioning hole 67e in the +Y direction, abutment portion 68A is restricted so as not to move in the +Y direction. Of the two regulated portions 68b, the regulated portion 68b located in the +X direction is given the reference symbol 68b-1, and the regulated portion 68b located in the -X direction is given the reference symbol 68b-2. Similarly, of the two regulated surfaces 68c, the regulated surface 68c located in the +X direction is given the reference symbol 68c-1, and the regulated surface 68c located in the -X direction is given the reference symbol 68c-2.

[0061] 8 and 10, the contact portion 68A is formed with a contact surface 68a that is parallel to the XZ plane. The contact surface 68a is a surface that the tip of the plunger 62 of the solenoid 61 contacts when the plunger 62 is displaced in the +Y direction, and defines the displacement limit of the plunger 62 in the +Y direction. 13, a spring hook 63a is formed on the engagement member 63 attached to the plunger 62. A spring hook 67h is formed on the mounting frame 67, and a coil spring 73, which is an example of a pressing member, is provided between the spring hook 63a and the spring hook 67h. The coil spring 73 applies a pressing force in the +Y direction to the plunger 62, assisting the displacement of the plunger 62 in the +Y direction.

[0062] When the plunger 62 is displaced in the +Y direction, the tip of the plunger 62 abuts against the abutment surface 68a as described above. The dashed arrow in Fig. 13 indicates the transmission of vibration caused by the plunger 62 abutting against the abutment surface 68a, and this vibration is transmitted to the mounting frame 67 because the regulated surface 68c abuts against the edge of the positioning hole 67e in the +Y direction, and then toward the frame 59 as shown by the solid arrow. If this vibration is transmitted to the frame 59, there is a risk that noise will be generated due to the vibration of the frame 59. 13, the reference symbol d1 denotes a distance between the wall portion 68h forming the contact surface 68a and the edge portion 67k which is a portion of the second mounting portion 67B facing the wall portion 68h. By providing the distance d1, the impact when the plunger 62 contacts the contact surface 68a is transmitted to the second mounting portion 67B via the regulated surface 68c, not via the wall portion 68h. In addition, the screw insertion hole 68j, through which the abutment portion fixing screw 69 (see Figure 10) is inserted, is formed with a margin relative to the outer diameter of the abutment portion fixing screw 69, so that vibration is not transmitted from the inner periphery of the screw insertion hole 68j to the outer periphery of the abutment portion fixing screw 69, and the impact generated when the plunger 62 abuts against the abutment surface 68a is transmitted to the second mounting portion 67B via the regulated surface 68c. The above also applies to other embodiments described below.

[0063] Since the abutment portion 68 is attached to the frame 59 via the second attachment portion 67B, the vibration caused by the impact when the plunger 62 abuts against the abutment portion 68 is transmitted to the frame 59 via the second attachment portion 67B from the abutment portion 68 as described above. This makes it difficult for the frame 59 to vibrate compared to a configuration in which the plunger 62 directly abuts against the second attachment portion 67B, and makes it possible to suppress noise caused by the vibration of the frame 59. From this viewpoint, it is preferable that the abutment portion 68 is made of a material having a lower elasticity than at least the frame 59. In this embodiment, the abutment portion 68 is made of a resin material, and the frame 59 is made of a metal material. However, the abutment portion 68 and the frame 59 may be made of the same material.

[0064] Next, FIG. 14 shows the positional relationship between the frame 59 and the two regulated surfaces 68c. In this embodiment, in the displacement direction of the plunger 62, i.e., the Y-axis direction, the frame 59 is located in the -Y direction with respect to the abutment portion 68. Reference symbol 68f denotes the -Y direction end of the abutment portion 68, i.e., a first end which is the end on the side where the plunger 62 abuts, and reference symbol 68g denotes the +Y direction end of the abutment portion 68, i.e., a second end opposite to the first end 68f. Note that the -Y direction is an example of the first direction, and the +Y direction is an example of the second direction. Of the two regulated surfaces 68c that engage with the second mounting portion 67B, the regulated surface 68c-2 is provided at a position between the first end 68f and the second end 68g in the Y-axis direction and closer to the second end 68g. In FIG. 14, the symbol Y1 indicates the position of the first end 68f in the Y-axis direction, the symbol Y2 indicates the position of the second end 68g in the Y-axis direction, and the symbol Yc indicates the intermediate position between the first end 68f and the second end 68g. The symbol Y3 indicates the position of the regulated surface 68c-1 in the Y-axis direction, and the symbol Y4 indicates the position of the regulated surface 68c-2 in the Y-axis direction. As shown in the figure, the position Y4 is located in the +Y direction, i.e., closer to the second end 68g, than the position Yc.

[0065] This provides the following effects. When the plunger 62 comes into contact with the contact portion 68, the contact portion 68 tries to move in the +Y direction. Here, in the Y-axis direction, the frame 59 is located in the -Y direction with respect to the contact portion 68, and therefore the further the regulated surface 68c is positioned in the +Y direction, the more the distance between the regulated surface 68c and the frame 59 can be secured, and as a result, vibrations due to impact are further attenuated, and the generation of noise can be further suppressed. In this embodiment, the regulated surface 68c-2 is provided at a position between the first end 68f and the second end 68g and closer to the second end 68g in the Y-axis direction, which is the moving direction of the plunger 62, and therefore it is possible to ensure a distance between the regulated surface 68c-2 and the frame 59. As a result, vibrations due to impacts are further attenuated, and noise generation can be further suppressed.

[0066] In this embodiment, the regulated surface 68c-1 is located closer to the first end 68f between the first end 68f and the second end 68g, but may be located closer to the second end 68g like the regulated surface 68c-2. In this embodiment, the contact portion 68 has two regulated surfaces 68c, but may have one regulated surface 68c, or may have three or more regulated surfaces 68c. In this case, all of the regulated surfaces 68c may be located closer to the second end 68g between the first end 68f and the second end 68g, or only some of them may be located closer to the second end 68g. The second end 68g may be used as the regulated surface 68c.

[0067] Next, a solenoid device 60B according to a second embodiment will be described with reference to Figures 15 to 19. In the following description, the same components as those already described will be given the same reference numerals, and duplicated descriptions will be avoided. The solenoid device 60B has an abutment portion 68B instead of the above-mentioned abutment portion 68A. The abutment portion 68B has a regulated portion 68b as shown in Fig. 17. The regulated portion 68b according to this embodiment is formed in a boss shape, and the regulated surface 68c is the surface of the outer circumferential surface of the regulated portion 68b that is visible from the +Y direction. That is, in this embodiment, the regulated surface 68c is an arc-shaped surface. In FIG. 18, the regulated surface 68c-2 is provided at a position between the first end 68f and the second end 68g in the Y-axis direction and closer to the second end 68g, as described with reference to FIG. The contact portion 68B has a screw insertion hole 68e1 through which the contact portion fixing screw 69 is inserted.

[0068] A slit 68d is formed in the contact portion 68B at a position between the first end 68f and the second end 68g and closer to the first end 68f so as to extend in the X-axis direction. This allows the wall portion 68h forming the contact surface 68a to temporarily deform in the +Y direction when the tip of the plunger 62 contacts the contact surface 68a. This makes it possible to further suppress the impact when the plunger 62 abuts against the abutment portion 68B, thereby further suppressing the vibration caused by the impact, and further suppressing the noise generated from the frame 59. Also, the impact when the plunger 62 abuts against the abutment portion 68B can be suppressed, for example, by providing a cushioning material on the abutment surface 68a, but in this case, there is a risk of a decrease in the positioning accuracy of the plunger 62. However, by providing a slit 68d between the first end 68f and the second end 68g and configuring the wall portion 68h to return to its original state after being temporarily deformed, it becomes easier to ensure the positioning accuracy of the plunger 62 compared to a configuration in which a cushioning material is provided.

[0069] In this embodiment, the slit 68d overlaps with an area A2 obtained by extending the movement area A1 of the plunger 62 in the +Y direction. This makes it possible to effectively suppress the impact when the plunger 62 abuts against the abutment portion 68B. As a result, the vibration caused by the impact is effectively suppressed, and further the noise generated from the frame 59 can be more effectively suppressed.

[0070] Next, a solenoid device 60C according to a third embodiment will be described with reference to FIGS. The solenoid device 60C differs from the above-described solenoid device 60B in that a vibration damping member 75 is provided, and that a shoulder screw is used as the abutment portion fixing screw 70 for fixing the abutment portion 68C to the second attachment portion 67B.

[0071] The contact portion 68C is formed with a screw insertion hole 68e2 for inserting the contact portion fixing screw 70. The screw insertion hole 68e2 is formed in a stepped shape to correspond to the contact portion fixing screw 70, which is a stepped screw, as shown in FIG. When the abutment portion fixing screw 70 is fitted into the screw hole 67j, a gap g1 is formed between the flange portion 70a of the abutment portion fixing screw 70 and the step portion of the screw insertion hole 68e2.

[0072] Between the contact portion 68C and the second attachment portion 67B, a vibration damping member 75 is provided. The vibration damping member 75 is an elastic member, and as an example, an elastic material such as sponge or rubber can be used.

[0073] Since the vibration damping member 75 is interposed between the abutment portion 68C and the second mounting portion 67B in this manner, the vibration caused by the impact when the plunger 62 abuts against the abutment surface 68a is further damped, and the generation of noise from the frame 59 can be further suppressed.

[0074] Furthermore, the +Z direction surface of the vibration damping member 75, which is a first surface, contacts the -Z direction surface of the contact portion 68C. Furthermore, the -Z direction surface of the vibration damping member 75, which is a second surface opposite to the first surface, contacts the +Z direction surface of the second attachment portion 67B. This makes it possible to damp vibrations transmitted from the -Z direction surface of the contact portion 68C to the +Z direction surface of the second attachment portion 67B. In addition, when vibration is transmitted through the second mounting portion 67B as shown by the solid arrow, the -Z direction surface of the vibration damping member 75 is in contact with the second mounting portion 67B, thereby damping the vibration transmitted through the second mounting portion 67B. As a result of the above, the generation of noise from the frame 59 can be further suppressed.

[0075] As described above, the contact portion 68C has a gap g1 formed between the flange portion 70a of the contact portion fixing screw 70 and the step portion of the screw insertion hole 68e2, whereby the contact portion 68C is provided on the second mounting portion 67B with play in the Z-axis direction, i.e., in the direction intersecting the displacement direction of the plunger 62. As a result, vibration transmitted from the contact portion 68C to the second mounting portion 67B can be suppressed, and thus the generation of noise generated from the frame 59 can be further suppressed.

[0076] 21, the first end 68f, the vibration damping member 75, the regulated surface 68c-2, and the second end 68g are positioned in this order along the +Y direction. In this configuration, the vibration damping member 75 is positioned between the first end 68f and the regulated surface 68c-2, so that in a configuration in which vibration is transmitted to the second attachment portion 67B via the regulated surface 68c-2 and then to the frame 59, it is possible to damp vibration from the regulated surface 68c-2 toward the frame 59. As a result, it is possible to further suppress the generation of noise generated from the frame 59.

[0077] In the solenoid device 60A according to the first embodiment described above, the contact portion 68A may be provided with a slit similar to the slit 60d formed in the contact portions 68B and 68C. In the solenoid device 60A according to the first embodiment described above, the vibration damping member 75 described with reference to FIGS. 20 and 21 may be provided between the contact portion 68A and the second attachment portion 67B. In the solenoid device 60A according to the first embodiment described above, the abutment portion fixing screw 69 may be a stepped screw like the abutment portion fixing screw 70 described with reference to Figures 20 and 21, and a gap g1 may be provided as described with reference to Figure 21.

[0078] In the solenoid device 60C according to the third embodiment described above, the abutment portion 68C may omit the slit 68d. In the solenoid device 60C according to the third embodiment described above, the vibration damping member 75 may be omitted. In the solenoid device 60C according to the third embodiment described above, the contact portion fixing screw 70, which is a shoulder screw, may be a normal screw, and the gap g1 described with reference to FIG. 21 may be omitted. That is, in the solenoid device 60C according to the third embodiment described above, at least one of the slit 68d, the vibration damping member 75, and the contact portion fixing screw 70 which is a shoulder screw may be adopted, or any two of them may be adopted.

[0079] The present invention is not limited to the embodiments described above, and various modifications are possible within the scope of the invention described in the claims, and it goes without saying that these modifications are also included in the scope of the present invention.
