Description
本発明は、ジャム検出機構および走査装置に関する。
The present invention relates to a jam detection mechanism and a scanning device.
従来から特許文献１に開示されているようなジャム検出機構は、キャリッジ（走査体）の内側に折り曲げ自在に板状部材を配設しており、板状部材が走査体の内側へ折れ曲がることでメディアの浮き上がり（ジャム）を検出する。
Conventionally, a jam detection mechanism as disclosed in Patent Document 1 has a plate-like member disposed inside a carriage (scanning body) so as to be foldable, and the plate-like member is bent inside the scanning body. Detects media lift (jam).
ところで、板状部材が走査体の内側へ折れ曲がることでメディアのジャムを検出するジャム検出機構では、板状部材が走査体の内側へのみ折れ曲がるため、メディアのジャム部分が走査体の直下に侵入してしまった場合、走査体をジャム部分から脱する際には、板状部材は走査体の内側から外側には折れ曲がらない。このため、走査体をジャム部分から脱する際に、ジャム部分が板状部材に引っかかってしまい、メディアを傷つけたり汚したりするという問題がある。
By the way, in the jam detection mechanism that detects the jam of the medium by bending the plate-like member to the inside of the scanning body, since the plate-like member bends only to the inside of the scanning body, the jam portion of the media enters directly under the scanning body. In this case, when the scanning body is removed from the jammed portion, the plate member is not bent from the inside to the outside of the scanning body. For this reason, when removing a scanning body from a jam part, a jam part will be caught in a plate-shaped member, and there exists a problem that a medium is damaged or gets dirty.
本発明は、上記に鑑みてなされたものであって、メディアが傷つけられたり汚れたりすることを抑制することができるジャム検出機構および走査装置を提供することを目的とする。
The present invention has been made in view of the above, and an object of the present invention is to provide a jam detection mechanism and a scanning device capable of suppressing the media from being damaged or soiled.
上述した課題を解決し、目的を達成するために、本発明に係るジャム検出機構は、メディアと対向しつつ走査方向に往復動する走査体に取り付け可能な本体部材と、前記本体部材に配設され、前記走査方向に移動可能に前記本体部材に支持される連結部材と、前記連結部材に対して前記メディア側に配設され、前記走査方向に移動可能に前記連結部材に支持されており、前記メディアの状態に応じて、前記メディアと当接可能な当接部材と、前記連結部材が前記本体部材に対して前記走査方向のうち一方に向かって移動することを規制し、かつ、前記連結部材が前記本体部材に対して前記走査方向のうち他方に向かって移動することを許容する第一規制機構と、前記当接部材が前記連結部材に対して前記走査方向のうち前記他方に向かって移動することを規制し、かつ、前記当接部材が前記連結部材に対して前記走査方向のうち前記一方に向かって移動することを許容する第二規制機構と、前記当接部材が前記走査方向に移動したことを検出するセンサーと、を備えることを特徴とする。
In order to solve the above-described problems and achieve the object, a jam detection mechanism according to the present invention is provided with a main body member that can be attached to a scanning body that reciprocates in a scanning direction while facing a medium, and disposed on the main body member. A connecting member supported by the body member so as to be movable in the scanning direction; and disposed on the medium side with respect to the connecting member, and supported by the connecting member so as to be movable in the scanning direction; According to the state of the medium, the contact member capable of contacting the medium and the connecting member are restricted from moving toward one of the scanning directions with respect to the main body member, and the connection A first restricting mechanism that allows the member to move toward the other of the scanning directions with respect to the main body member; and the contact member toward the other of the scanning directions with respect to the connecting member. A second restricting mechanism that restricts movement and allows the contact member to move toward the one of the scanning directions with respect to the connecting member; and the contact member in the scanning direction. And a sensor for detecting the movement.
この発明では、第一規制機構により連結部材が他方に向かって移動することのみが許容され、第二規制機構により当接部材が一方に向かってのみ移動することが許容される。このために、当接部材に走査方向のうち一方に向かって外力が作用すると、当接部材のみが一方に向かって移動し、当接部材に走査方向のうち他方に向かって外力が作用すると、連結部材と当接部材とが一体に他方に向かって移動する。したがって、走査体に対して当接部材が、走査方向の一方と他方の双方に回転することとなるので、当接部材がメディアに引っかかることを抑制することができ、メディアが傷つけられたり汚れたりすることを抑制することができる。
In the present invention, the first restricting mechanism only allows the connecting member to move toward the other side, and the second restricting mechanism allows the contact member to move only toward one side. For this reason, when an external force acts on one side in the scanning direction on the contact member, only the contact member moves toward one side, and when an external force acts on the other side in the scanning direction on the contact member, The connecting member and the abutting member move together toward the other. Therefore, the contact member rotates with respect to the scanning body in one and the other in the scanning direction, so that the contact member can be prevented from being caught by the medium, and the medium can be damaged or soiled. Can be suppressed.
また、上記ジャム検出機構は、連結部材を本体部材に対して走査方向の両方向に揺動可能に支持し、当接部材を連結部材に対して走査方向の両方向に揺動可能に支持し、付勢手段が当接部材を基準位置に位置付ける付勢力を生じさせる。このために、当接部材に外力が作用しない状態では、走査体が走査方向に往復動しても、当接部材が回転することを規制でき、当接部材を基準位置に位置付けることができる。
The jam detection mechanism supports the connecting member so as to be swingable in both directions of the scanning direction with respect to the main body member, and supports the contact member so as to be swingable in both directions of the scanning direction of the connecting member. The biasing means generates a biasing force that positions the contact member at the reference position. For this reason, in the state where no external force acts on the contact member, even if the scanning body reciprocates in the scanning direction, the contact member can be restricted from rotating, and the contact member can be positioned at the reference position.
また、上記ジャム検出機構において、前記当接部材には、前記センサーが検出するセンサー検出部が設けられており、前記センサーは、前記本体部材に設けられており、前記センサー検出部が前記センサーに対して移動したことを検出することが好ましい。
In the jam detection mechanism, the contact member is provided with a sensor detection unit that detects the sensor, the sensor is provided in the main body member, and the sensor detection unit is provided in the sensor. It is preferable to detect the movement.
この発明では、当接部材にセンサー検出部を設け、本体部材に当接部材の移動を検出するセンサーを設けている。このように、走査体に対して走査方向の一方と他方の双方に移動する当接部材に、センサーが検出するセンサー検出部を設けているので、センサーを一つのみ設けても、当接部材の走査方向の一方と他方の双方の移動を検出できる。したがって、走査体が走査方向の一方と他方の双方に移動する際のメディアのジャムを検出でき、部品点数が増加することを抑制することができる。
In the present invention, the sensor detection unit is provided in the contact member, and the sensor for detecting the movement of the contact member is provided in the main body member. As described above, since the sensor detection unit that the sensor detects is provided in the contact member that moves in one of the scanning direction and the other in relation to the scanning body, even if only one sensor is provided, the contact member It is possible to detect the movement of one and the other in the scanning direction. Therefore, it is possible to detect a jam of the medium when the scanning body moves in one direction and the other in the scanning direction, and to suppress an increase in the number of parts.
また、上記ジャム検出機構において、前記付勢手段は、前記第一揺動軸と前記第二揺動軸との中間部に位置し、かつ、両端部が前記本体部材と前記当接部材とに支持されており、前記当接部材における前記付勢手段の支持位置から、前記第一揺動軸までの距離と、前記支持位置から前記第二揺動軸までの距離とが等しいことが好ましい。
Further, in the jam detection mechanism, the biasing means is located at an intermediate portion between the first swing shaft and the second swing shaft, and both end portions are connected to the main body member and the contact member. Preferably, the distance from the support position of the urging means in the contact member to the first swing shaft is equal to the distance from the support position to the second swing shaft.
この発明では、支持位置から第一揺動軸までの距離と、支持位置から第二揺動軸までの距離とが等しいので、走査体に対して当接部材が一方の方向に回転する際の付勢手段の付勢力と、走査体に対して当接部材が他方の方向に回転する際の付勢手段の付勢力とが等しくなる。このために、当接部材が一方の方向と他方の方向に回転する際のジャムを同様に検出することができる。
In this invention, since the distance from the support position to the first swing shaft is equal to the distance from the support position to the second swing shaft, the contact member is rotated in one direction with respect to the scanning body. The urging force of the urging means is equal to the urging force of the urging means when the contact member rotates in the other direction with respect to the scanning body. For this reason, it is possible to similarly detect a jam when the contact member rotates in one direction and the other direction.
上述した課題を解決し、目的を達成するために、本発明に係る走査装置は、メディアと対向しつつ走査方向に往復動する走査体と、前記走査体に取り付けられたジャム検出機構と、を備える走査装置であって、前記ジャム検出機構は、前記走査体に取り付け可能な本体部材と、前記本体部材に配設され、前記走査方向に移動可能に前記本体部材に支持される連結部材と、前記連結部材に対して前記メディア側に配設され、前記走査方向に移動可能に前記連結部材に支持されており、前記メディアの状態に応じて、前記メディアと当接可能な当接部材と、前記連結部材が前記本体部材に対して前記走査方向のうち一方に向かって移動することを規制し、かつ、前記連結部材が前記本体部材に対して前記走査方向のうち他方に向かって移動することを許容する第一規制機構と、前記当接部材が前記連結部材に対して前記当接部材の前記走査方向のうち前記他方に向かって移動することを規制し、かつ、前記当接部材が前記連結部材に対して前記走査方向のうち前記一方に向かって移動することを許容する第二規制機構と、前記当接部材が前記走査方向に移動したことを検出するセンサーとを備えることを特徴とする。

The jam detection mechanism includes a main body member that can be attached to the scanning body, a connecting member that is disposed on the main body member and is supported by the main body member so as to be movable in the scanning direction, An abutting member disposed on the medium side with respect to the coupling member, supported by the coupling member so as to be movable in the scanning direction, and capable of abutting on the medium according to a state of the medium; The connecting member is restricted from moving toward one of the scanning directions with respect to the main body member, and the connecting member is moved toward the other of the scanning directions with respect to the main body member. A first restricting mechanism that allows the contact member to move toward the other of the scanning directions of the contact member with respect to the connecting member, and the contact member A second restriction mechanism that allows the connecting member to move toward the one of the scanning directions, and a sensor that detects that the contact member has moved in the scanning direction. And
この発明では、前述したジャム検出機構を備えているので、当接部材がメディアに引っかかることを抑制することができ、メディアが傷つけられたり汚れたりすることを抑制することができる。
In the present invention, since the above-described jam detection mechanism is provided, the contact member can be prevented from being caught by the medium, and the medium can be prevented from being damaged or soiled.
また、上記走査装置において、前記当接部材の当接部から前記メディアの表面までの距離が、前記走査体の前記メディアと対向する対向部から前記表面までの距離より短いことが好ましい。
In the scanning device, it is preferable that the distance from the contact portion of the contact member to the surface of the medium is shorter than the distance from the facing portion of the scanning body facing the medium to the surface.
この発明では、メディアにジャムが生じても、走査体よりも当接部材の当接部がメディアに先に接触するので、走査体の主走査方向の一方の端面のみにジャム検出機構を設けても、走査体にメディアが接触する前にメディアのジャムを検出することができる。
In the present invention, even if a jam occurs in the medium, the abutting portion of the abutting member comes in contact with the medium in advance of the scanning body. Therefore, a jam detecting mechanism is provided only on one end surface in the main scanning direction of the scanning body. In addition, it is possible to detect a jam of the medium before the medium contacts the scanning body.
特に、走査体にプリンタヘッドが搭載され、前記走査方向が前記メディアが搬送される搬送方向と直交する方向である場合には、ジャムがヘッドに接触するよりも先にジャム検出機構がジャムを検出することで、ヘッドにジャムが接触する前に走査体の動作を停止させることができ、プリンタヘッドへ影響を与えることなく走査体をメディアのジャム部分から脱することができる。
In particular, when a printer head is mounted on the scanning body and the scanning direction is a direction perpendicular to the transport direction in which the medium is transported, the jam detection mechanism detects the jam before the jam contacts the head. By doing so, the operation of the scanning body can be stopped before the jam contacts the head, and the scanning body can be removed from the jammed portion of the medium without affecting the printer head.
本発明に係るジャム検出機構および走査装置は、メディアが傷つけられたり汚れたりすることを抑制することができる。

In the present embodiment, the first restricting mechanism 60 is a first abutting projecting from the side plate 24 of the main body member 20 and the upper end of the side plate 31 of the connecting member 30 that abuts the side plate 24 at the reference position. It is comprised from the protrusion 31a. In the first restricting mechanism 60, the first abutting protrusion 31 a abuts on the side plate 24, so that the connecting member 30 moves toward the one side in the main scanning direction around the first swing shaft 33 with respect to the main body member 20. Although the rotation is further restricted, the connection member 30 with respect to the main body member 20 is allowed to rotate in the main scanning direction around the first swing shaft 33.
第二規制機構７０は、図７に示すように、基準位置における当接部材４０に対して、主走査方向のうち他方に向かって外力が作用した際に、連結部材３０に対して当接部材４０が主走査方向のうち他方に向かって回転（移動）することを規制し、かつ、連結部材３０に対して当接部材４０が主走査方向のうち一方に向かって回転（移動）することを許容するものである。本実施形態では、第二規制機構７０は、当接部材４０の側面板４１と、基準位置で側面板４１と当接する連結部材３０の側面板３１の鉛直方向の下端部から凸状に張り出した第二当接突起３１ｂとから構成されている。第二規制機構７０は、側面板４１に第二当接突起３１ｂが当接することで連結部材３０に対して当接部材４０が第二揺動軸４３回りに主走査方向の他方に向かって基準位置より回転することを規制するが、連結部材３０に対する当接部材４０の第二揺動軸４３回りの主走査方向の一方に向かう回転を許容する。
As shown in FIG. 7, the second regulating mechanism 70 is configured to contact the connecting member 30 when an external force is applied to the contact member 40 at the reference position toward the other side in the main scanning direction. 40 is restricted from rotating (moving) toward the other side in the main scanning direction, and the contact member 40 is rotated (moved) toward one side in the main scanning direction with respect to the connecting member 30. It is acceptable. In the present embodiment, the second regulating mechanism 70 protrudes in a convex shape from the lower end in the vertical direction of the side plate 41 of the contact member 40 and the side plate 31 of the connecting member 30 that contacts the side plate 41 at the reference position. The second contact protrusion 31b is configured. The second regulating mechanism 70 is configured such that the second abutting protrusion 31b abuts on the side plate 41 so that the abutting member 40 is moved around the second swing shaft 43 toward the other in the main scanning direction with respect to the connecting member 30. Although rotation from the position is restricted, the contact member 40 with respect to the connecting member 30 is allowed to rotate in the main scanning direction around the second swing shaft 43.
このために、付勢手段５０は、当接部材４０に主走査方向の一方の方向に外力が作用すると、第一規制機構６０により本体部材２０に対する連結部材３０の回転は規制され、当接部材４０のみが連結部材３０及び本体部材２０に対して第二揺動軸４３回りに主走査方向の一方に向かう回転をし、伸張される。これにより、付勢手段５０は、本体部材２０に対して基準位置に位置付ける付勢力を当接部材４０に作用させる。また、付勢手段５０は、当接部材４０に主走査方向の他方の方向に外力が作用すると、第二規制機構７０により連結部材３０に対する当接部材４０の回転が規制されているために、当接部材４０と連結部材３０とが一体となって本体部材２０に対して第一揺動軸３３回りに主走査方向の他方に向かう回転をし、伸張される。これにより、付勢手段５０は、当接部材４０を連結部材３０とともに本体部材２０に対して基準位置に位置付ける付勢力を当接部材４０に作用させる。
For this reason, when an external force acts on the contact member 40 in one direction of the main scanning direction, the biasing means 50 restricts the rotation of the connecting member 30 relative to the main body member 20 by the first restriction mechanism 60, and the contact member Only 40 rotates with respect to the connecting member 30 and the body member 20 around the second swing shaft 43 in one direction of the main scanning direction, and is extended. Thereby, the urging means 50 causes the urging force to be positioned at the reference position with respect to the main body member 20 to the contact member 40. Further, when the external force acts on the contact member 40 in the other direction of the main scanning direction, the biasing means 50 restricts the rotation of the contact member 40 relative to the connecting member 30 by the second restriction mechanism 70. The contact member 40 and the connecting member 30 are integrally rotated with respect to the main body member 20 around the first swing shaft 33 toward the other side in the main scanning direction. Thereby, the urging means 50 causes the urging force to position the abutting member 40 together with the connecting member 30 at the reference position with respect to the main body member 20 to the abutting member 40.
また、前述した当接部材４０には、センサー８０が検出するセンサー検出部４４が一体に設けられている。センサー検出部４４は、図４及び図６に示すように、複数の補強板４２ａ，４２ｂのうち、最も上方の補強板４２ｂの上端部から鉛直方向の上方に延在され、副走査方向の幅より主走査方向の幅が大きい平板状に形成されている。センサー検出部４４は、鉛直方向において、第一揺動軸３３と第二揺動軸４３との間に位置している。センサー検出部４４は、副走査方向において、本体部材２０の天板２１に設けられた一対の装着孔２１ａ間に配置されている。このため、センサー検出部４４は、連結部材３０に対して当接部材４０が主走査方向の一方に向かって回転する際には、センサー８０に対して第二揺動軸４３回りに主走査方向の他方に向かって回転することで、センサー８０に対して主走査方向の他方に向かって移動する。一方、本体部材２０に対して連結部材３０と当接部材４０とが一体となって主走査方向の他方に向かって回転する際には、センサー８０に対して第一揺動軸３３回りに主走査方向の他方に向かって回転することで、センサー８０に対して主走査方向の一方に向かって移動する。
Further, the above-described contact member 40 is integrally provided with a sensor detection unit 44 that the sensor 80 detects. As shown in FIGS. 4 and 6, the sensor detection unit 44 extends from the upper end of the uppermost reinforcing plate 42b among the plurality of reinforcing plates 42a and 42b in the vertical direction, and has a width in the sub-scanning direction. It is formed in a flat plate shape having a larger width in the main scanning direction. The sensor detection unit 44 is located between the first swing shaft 33 and the second swing shaft 43 in the vertical direction. The sensor detection unit 44 is disposed between a pair of mounting holes 21 a provided in the top plate 21 of the main body member 20 in the sub-scanning direction. Therefore, when the contact member 40 rotates toward the one side in the main scanning direction with respect to the connecting member 30, the sensor detection unit 44 rotates around the second swing shaft 43 with respect to the sensor 80 in the main scanning direction. By rotating toward the other of the sensors, the sensor 80 moves toward the other in the main scanning direction. On the other hand, when the connecting member 30 and the abutting member 40 are integrated with the main body member 20 and rotate toward the other side in the main scanning direction, the main member 20 is rotated around the first swing shaft 33 with respect to the sensor 80. By rotating toward the other side in the scanning direction, the sensor 80 moves toward one side in the main scanning direction.
センサー８０は、キャリッジ８が主走査方向の往復運動中に、当接部材４０がメディアＭと接触することで、本体部材２０に対して基準位置から当接部材４０が主走査方向に移動したことを検出するものである。センサー８０は、一方の装着孔２１ａ内に装着されかつ基準位置のセンサー検出部４４に対向して検出光を出射する発光素子８１ａと、他方の装着孔２１ａ内に装着されかつセンサー検出部４４が基準位置から移動することにより発光素子８１ａの検出光を受光可能となる受光素子８１ｂと、を備える。こうして、センサー８０は、発光素子８１ａ及び受光素子８１ｂが装着孔２１ａ内に装着されることで、本体部材２０に設けられる。センサー８０は、基準位置に当接部材４０が位置すると、発光素子８１ａの出射する検出光がセンサー検出部４４により遮られて受光素子８１ｂに受光されない。
The sensor 80 is configured such that the contact member 40 is moved in the main scanning direction from the reference position with respect to the main body member 20 when the contact member 40 is in contact with the medium M while the carriage 8 is reciprocating in the main scanning direction. Is detected. The sensor 80 is mounted in one mounting hole 21a and emits detection light facing the sensor detection unit 44 at the reference position, and the sensor 80 is mounted in the other mounting hole 21a and the sensor detection unit 44 includes And a light receiving element 81b that can receive the detection light of the light emitting element 81a by moving from the reference position. Thus, the sensor 80 is provided in the main body member 20 by mounting the light emitting element 81a and the light receiving element 81b in the mounting hole 21a. In the sensor 80, when the contact member 40 is positioned at the reference position, the detection light emitted from the light emitting element 81a is blocked by the sensor detection unit 44 and is not received by the light receiving element 81b.
センサー８０は、本体部材２０に対して当接部材４０が主走査方向の一方又は他方に向かって回転すると、発光素子８１ａの出射する検出光がセンサー検出部４４により遮られなくなり受光素子８１ｂに受光される。このように、センサー８０は、当接部材４０が基準位置にあり、センサー検出部４４とセンサー８０とが対向していることを検出し、また、当接部材４０が本体部材２０に対して基準位置から主走査方向に向かって回転することで、センサー検出部４４がセンサー８０に対して移動したことを検出する。こうして、センサー８０は、発光素子８１ａが出射する検出光を受光素子８１ｂが受光する又は受光しないことを検出することで、本体部材２０に対して当接部材４０が基準位置から主走査方向の一方又は他方に回転したことを検出する。センサー８０は、検出結果を制御装置７のジャム検出部７３に出力する。
When the contact member 40 rotates toward the one or the other in the main scanning direction with respect to the main body member 20, the sensor 80 receives the light received by the light receiving element 81b because the detection light emitted from the light emitting element 81a is not blocked by the sensor detection unit 44. Is done. As described above, the sensor 80 detects that the contact member 40 is at the reference position and the sensor detection unit 44 and the sensor 80 face each other, and the contact member 40 is the reference with respect to the main body member 20. By rotating from the position in the main scanning direction, it is detected that the sensor detection unit 44 has moved relative to the sensor 80. Thus, the sensor 80 detects that the light receiving element 81b receives or does not receive the detection light emitted from the light emitting element 81a, so that the abutting member 40 moves from the reference position to one side in the main scanning direction. Or it detects that it rotated to the other. The sensor 80 outputs the detection result to the jam detection unit 73 of the control device 7.
以上のように構成された実施形態に係る走査装置４及びジャム検出機構１０の動作について説明する。なお、本実施形態では、走査装置４は、インクジェットプリンタ１に搭載されている。
The operation of the scanning device 4 and the jam detection mechanism 10 according to the embodiment configured as described above will be described. In the present embodiment, the scanning device 4 is mounted on the ink jet printer 1.
走査装置４は、キャリッジ駆動制御部７１によりキャリッジ駆動装置５が制御され、メディア搬送制御部７２によりメディア搬送装置６が制御されることで、キャリッジ８が主走査方向に往復動し、キャリッジ８とメディアＭとが副走査方向に相対移動されながらプリンタヘッド９からインクを吐出して、メディアＭに対して印刷を行う。
In the scanning device 4, the carriage drive device 5 is controlled by the carriage drive control unit 71, and the media conveyance device 6 is controlled by the media conveyance control unit 72, so that the carriage 8 reciprocates in the main scanning direction. Ink is ejected from the printer head 9 while the medium M is relatively moved in the sub-scanning direction, and printing is performed on the medium M.
ここで、図６に示すように、Ｙバー３に沿ってキャリッジ８が主走査方向の他方に向かって移動される時に、メディアＭの載置台２から浮き上がったジャム部分Ｍａが発生すると、ジャム部分Ｍａが当接部材４０の当接部４１ａ，４１ｂなどに当接する。すると、当接部材４０の当接部４１ａ，４１ｂに主走査方向の一方に向かう外力が作用する。この場合、第一規制機構６０は、連結部材３０が本体部材２０に対して第一揺動軸３３回りに主走査方向の一方に向かって回転することを規制しており、第二規制機構７０は、当接部材４０が連結部材３０に対して第二揺動軸４３回りに主走査方向の一方に向かって回転することを許容しているので、図６に示すように、当接部４１ａ，４１ｂが主走査方向の一方の方向に向かうように、当接部材４０（当接部４１ａ，４１ｂ）が連結部材３０及び本体部材２０に対して第二揺動軸４３回りに回転する。
Here, as shown in FIG. 6, when a jam portion Ma is lifted from the mounting table 2 of the medium M when the carriage 8 is moved along the Y bar 3 toward the other side in the main scanning direction, the jam portion Ma contacts the contact portions 41a and 41b of the contact member 40. Then, an external force directed to one of the main scanning directions acts on the contact portions 41a and 41b of the contact member 40. In this case, the first restricting mechanism 60 restricts the connecting member 30 from rotating around the first swing shaft 33 toward one side in the main scanning direction with respect to the main body member 20, and the second restricting mechanism 70. Since the contact member 40 allows the connection member 30 to rotate about the second swing shaft 43 toward one side in the main scanning direction, as shown in FIG. 6, the contact portion 41a. , 41b is directed to one direction of the main scanning direction, the contact member 40 ( contact portions 41a, 41b) rotates about the second swing shaft 43 with respect to the connecting member 30 and the main body member 20.
また、当接部４１ａ，４１ｂが主走査方向の一方の方向に向かうように、当接部材４０が連結部材３０及び本体部材２０に対して第二揺動軸４３回りに回転すると、付勢手段５０が伸張されて、付勢手段５０が当接部材４０を基準位置に付勢する付勢力を生じさせる。このために、当接部材４０の当接部４１ａ，４１ｂにジャム部分Ｍａなどが当接しなくなると、当接部材４０が基準位置に復帰する。
Further, when the contact member 40 rotates around the second swing shaft 43 with respect to the connecting member 30 and the main body member 20 so that the contact portions 41a and 41b are directed in one direction of the main scanning direction, the urging means 50 is extended, and the biasing means 50 generates a biasing force that biases the contact member 40 to the reference position. For this reason, when the jam portion Ma or the like does not contact the contact portions 41a and 41b of the contact member 40, the contact member 40 returns to the reference position.
また、図７に示すように、Ｙバー３に対してキャリッジ８が主走査方向の一方に向かって移動される時に、メディアＭの載置台２から浮き上がったジャム部分Ｍａが発生すると、ジャム部分Ｍａが当接部材４０の当接部４１ａ，４１ｂなどに当接する。すると、当接部材４０の当接部４１ａ，４１ｂに主走査方向の他方に向かう外力が作用する。この場合、第一規制機構６０は、連結部材３０が本体部材２０に対して第一揺動軸３３回りに主走査方向の他方に向かって回転することを許容しており、第二規制機構７０は、当接部材４０が連結部材３０に対して第二揺動軸４３回りに主走査方向の他方に向かって回転することを規制しているので、図７に示すように、当接部４１ａ，４１ｂが主走査方向の他方の方向に向かうように、当接部材４０と連結部材３０とが一体となって本体部材２０に対して第一揺動軸３３回りに回転する。また、当接部４１ａ，４１ｂが主走査方向の他方の方向に向かうように、当接部材４０と連結部材３０とが一体となって本体部材２０に対して第一揺動軸３３回りに回転すると、付勢手段５０が伸張されて、付勢手段５０が当接部材４０を基準位置に付勢する付勢力を生じさせる。このために、当接部材４０の当接部４１ａ，４１ｂにジャム部分Ｍａなどが当接しなくなると、当接部材４０が基準位置に復帰する。
Further, as shown in FIG. 7, when the jam portion Ma is lifted from the mounting table 2 of the medium M when the carriage 8 is moved toward one side in the main scanning direction with respect to the Y bar 3, the jam portion Ma is generated. Comes into contact with the contact portions 41a and 41b of the contact member 40. Then, an external force directed to the other in the main scanning direction acts on the contact portions 41a and 41b of the contact member 40. In this case, the first restricting mechanism 60 allows the connecting member 30 to rotate about the first swing shaft 33 toward the other side in the main scanning direction with respect to the main body member 20, and the second restricting mechanism 70. Restricts the contact member 40 from rotating about the second swing shaft 43 toward the other in the main scanning direction with respect to the connecting member 30, and as shown in FIG. , 41b are directed around the first swing shaft 33 relative to the main body member 20 so that the contact member 40 and the connecting member 30 are united so that the other direction of the main scanning direction is directed. Further, the contact member 40 and the connecting member 30 are integrally rotated about the first swing shaft 33 with respect to the main body member 20 so that the contact portions 41a and 41b are directed in the other direction of the main scanning direction. Then, the urging means 50 is expanded, and the urging means 50 generates an urging force that urges the contact member 40 to the reference position. For this reason, when the jam portion Ma or the like does not contact the contact portions 41a and 41b of the contact member 40, the contact member 40 returns to the reference position.
以上の実施形態に係るジャム検出機構１０によれば、第一規制機構６０により本体部材２０に対して連結部材３０が主走査方向の他方に向かって回転することが許容され、第二規制機構７０により連結部材３０に対して当接部材４０が主走査方向の一方に向かって回転することが許容される。このために、当接部材４０に主走査方向のうち一方に向かって外力が作用すると、当接部材４０のみが一方に向かって回転し、当接部材４０に主走査方向のうち他方に向かって外力が作用すると、連結部材３０と当接部材４０とが一体に他方に向かって回転する。したがって、キャリッジ８に対して当接部材４０が、主走査方向の一方と他方の双方に回転することとなるので、当接部材４０がメディアＭに引っかかることを抑制することができ、メディアＭが傷つけられたり汚れたりすることを抑制することができる。
According to the jam detection mechanism 10 according to the above embodiment, the first restriction mechanism 60 allows the connecting member 30 to rotate with respect to the main body member 20 toward the other side in the main scanning direction, and the second restriction mechanism 70. Accordingly, the contact member 40 is allowed to rotate toward one side in the main scanning direction with respect to the connecting member 30. For this reason, when an external force acts on one of the main scanning directions on the contact member 40, only the contact member 40 rotates toward one side, and the contact member 40 moves toward the other side in the main scanning direction. When an external force is applied, the connecting member 30 and the contact member 40 are integrally rotated toward the other side. Therefore, the contact member 40 rotates with respect to the carriage 8 in one and the other in the main scanning direction, so that the contact member 40 can be prevented from being caught by the medium M. It can be suppressed from being damaged or dirty.
また、第一規制機構６０が、本体部材２０に対して連結部材３０が一方に向かって回転することを規制し、第二規制機構７０が、連結部材３０に対して当接部材４０が他方に向かって回転することを規制し、付勢手段５０が当接部材４０を基準位置に位置付ける付勢力を生じさせる。このために、当接部材４０に外力が作用しない状態では、キャリッジ８が主走査方向に往復動しても、当接部材４０がキャリッジ８に対して回転することを規制でき、当接部材４０を基準位置に位置付けることができる。したがって、メディアＭのジャムの誤検出を抑制することができる。
Further, the first restricting mechanism 60 restricts the connecting member 30 from rotating toward the one side with respect to the main body member 20, and the second restricting mechanism 70 sets the contact member 40 to the other side with respect to the connecting member 30. The biasing means 50 generates a biasing force that positions the contact member 40 at the reference position. For this reason, in a state where no external force is applied to the contact member 40, even if the carriage 8 reciprocates in the main scanning direction, the contact member 40 can be restricted from rotating with respect to the carriage 8. Can be positioned at the reference position. Therefore, it is possible to suppress erroneous detection of the jam of the medium M.
また、ジャム検出機構１０では、当接部材４０にセンサー検出部４４を設け、本体部材２０に当接部材４０の基準位置からの回転を検出するセンサー８０を設けている。このように、キャリッジ８に対して主走査方向の一方と他方の双方に回転する当接部材４０にセンサー８０が検出するセンサー検出部４４を設け、キャリッジ８に固定される本体部材２０にセンサー８０を設けている。このために、センサー８０を一つのみ設けても、当接部材４０の主走査方向の一方と他方の双方の回転を検出できる。したがって、キャリッジ８が主走査方向の一方と他方の双方に移動する際のメディアＭのジャム部分Ｍａを検出でき、部品点数が増加することを抑制することができる。
Further, in the jam detection mechanism 10, the sensor detection unit 44 is provided in the contact member 40, and the sensor 80 that detects the rotation of the contact member 40 from the reference position is provided in the main body member 20. As described above, the sensor detection unit 44 that detects the sensor 80 is provided on the contact member 40 that rotates in the main scanning direction with respect to the carriage 8, and the sensor 80 is provided on the main body member 20 that is fixed to the carriage 8. Is provided. For this reason, even if only one sensor 80 is provided, it is possible to detect the rotation of one and the other of the contact member 40 in the main scanning direction. Therefore, it is possible to detect the jammed portion Ma of the medium M when the carriage 8 moves in one side and the other side in the main scanning direction, and it is possible to suppress an increase in the number of parts.
ジャム検出機構１０では、支持位置Ａから第一揺動軸３３までの距離と、支持位置Ａから第二揺動軸４３までの距離とが等しいので、キャリッジ８に対して当接部材４０が主走査方向の一方の方向に回転する際の付勢手段５０の付勢力と、キャリッジ８に対して当接部材４０が主走査方向の他方の方向に回転する際の付勢手段５０の付勢力とが等しくなる。このために、当接部材４０が主走査方向の一方の方向と他方の方向に回転する際のジャムを同様に、つまり同程度の検出感度で検出することができる。
In the jam detection mechanism 10, the distance from the support position A to the first swing shaft 33 is equal to the distance from the support position A to the second swing shaft 43. The urging force of the urging means 50 when rotating in one direction of the scanning direction and the urging force of the urging means 50 when the contact member 40 rotates with respect to the carriage 8 in the other direction of the main scanning direction Are equal. For this reason, a jam when the contact member 40 rotates in one direction and the other direction in the main scanning direction can be detected in the same manner, that is, with the same detection sensitivity.
走査装置４は、前述したジャム検出機構１０を備えているので、当接部材４０がメディアＭに引っかかることを抑制することができ、メディアＭが傷つけられたり汚れたりすることを抑制することができる。
Since the scanning device 4 includes the jam detection mechanism 10 described above, the contact member 40 can be prevented from being caught by the medium M, and the medium M can be prevented from being damaged or dirty. .
また、走査装置４は、メディアＭにジャムが生じても、キャリッジ８よりも当接部材４０の当接部４１ａ，４１ｂがメディアＭに先に接触するので、キャリッジ８の主走査方向の他方の端部８ａのみにジャム検出機構１０を設けても、キャリッジ８にメディアＭが接触する前にメディアＭのジャム部分Ｍａを検出することができる。
In the scanning device 4, even if a jam occurs in the medium M, the abutting portions 41 a and 41 b of the abutting member 40 come in contact with the medium M earlier than the carriage 8. Even if the jam detection mechanism 10 is provided only at the end portion 8a, the jam portion Ma of the medium M can be detected before the medium M contacts the carriage 8.
なお、上記の実施形態では、走査装置４がインクジェットプリンタ１に配設されていたが、本発明ではこれに限定されない。即ち、本発明は、種々のメディアＭに対向して往復動する種々の走査体に取り付けてもよい。
In the above embodiment, the scanning device 4 is disposed in the ink jet printer 1, but the present invention is not limited to this. That is, the present invention may be attached to various scanning bodies that reciprocate against various media M.
前述したように、本発明の実施形態を説明したが、本発明は、これらに限定されない。本発明では、実施形態をその他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置き換え、組み合わせの変更等を行うことができる。
As described above, the embodiments of the present invention have been described, but the present invention is not limited thereto. In the present invention, the embodiment can be implemented in various other forms, and various omissions, replacements, combinations of changes, and the like can be made without departing from the spirit of the invention.
