Description

本発明は、各種電子・電気機器において、筐体に回動自在に取り付けたパネルを開閉するために使用されるパネル開閉機構に関し、詳しくはパネルを開く時（特に開く過程における動作時）における回動速度を制御するパネル開閉機構に関する。   The present invention relates to a panel opening / closing mechanism used for opening / closing a panel pivotally attached to a casing in various electronic / electrical devices, and more particularly to a rotation when opening the panel (especially during operation in the opening process). The present invention relates to a panel opening / closing mechanism for controlling a moving speed.

従来より、機器の筐体に回動自在に取着された扉やパネルを開閉する機構において、バネの付勢力をパネルを倒す方向に作用させるとともに、回転ダンパやシリンダとピストンを組み合わせたエアダンパ（直線形ダンパ）等を設けて速度を制御しながらパネルを開閉させる手段が多用されている。   Conventionally, in a mechanism that opens and closes a door or panel that is pivotally attached to the casing of a device, the biasing force of a spring acts in the direction of tilting the panel, and a rotary damper or an air damper that combines a cylinder and a piston ( A means for opening and closing the panel while controlling the speed by providing a linear damper) is often used.

例えば、特許文献１（特開平８−３０７０６６号公報）に開示されたパネル開閉装置は、操作パネルが回転軸を支点として、装置本体の前面を覆う閉鎖姿勢と、９０度前方へ倒れる開放姿勢との間を回動できるように支持されているものであって、操作パネルはバネの力で開放姿勢へ付勢されるが、回転軸に速度調整部材として回転ダンパが設けられていて、操作パネルを開く時（開く過程における動作時）における回動速度を減速させることができるものである。   For example, the panel opening / closing device disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 8-307066) has a closed posture in which the operation panel covers the front surface of the device main body with the rotation axis as a fulcrum, and an open posture in which the operation panel is tilted forward by 90 degrees. The operation panel is urged to the open position by the force of the spring, but the rotary shaft is provided with a rotation damper as a speed adjustment member. The rotation speed when opening the door (during the opening process) can be reduced.

特開平８−３０７０６６号公報JP-A-8-307066

しかしながら、回転ダンパにより操作パネルの回動速度はある程度制御されるが、下部を支軸として垂直に立設している操作パネルを開放姿勢にするため開く時（倒れる方向に回動させる時）には、操作パネルを自重による荷重が増す方向（倒れる方向）に回動させることになるため、９０度近く倒れる終速時に荷重がＭＡＸになって、回動する速度が最も速くなり高級感を損なっていた。   However, the rotational speed of the operation panel is controlled to some extent by the rotary damper, but when the operation panel standing vertically with the lower part as a support shaft is opened to be in an open position (when it is rotated in a tilting direction). Because the operation panel is rotated in the direction in which the load due to its own weight increases (the direction in which it falls), the load becomes MAX at the final speed when it falls nearly 90 degrees, and the rotational speed becomes the fastest, resulting in a loss of luxury. It was.

また、機器は机や床に設置する場合の他、機器を天井から吊して設置する場合があり、その場合には、机や床に設置する場合とは１８０度反転させて機器を設置することがある。つまり、机上に設置する場合と天井から吊す場合では、開放姿勢にするため開く時、前者は操作パネルが倒れることになり、後者は操作パネルが持ち上がることになるため、両者で操作パネルの自重による荷重がかかる方向が変わることになる。従って、操作パネルが自重による荷重がかかる方向に開く時、等速にするため荷重を押さえる抵抗を付加すると、天井に吊す場合はその抵抗によって回動する速度を遅くしてしまうため、両者間での速度の違和感が大きすぎて、高級感を損なうという問題が発生した。   In addition to installing the device on a desk or floor, the device may be installed suspended from the ceiling. In that case, install the device by inverting 180 degrees from the case of installing the device on the desk or floor. Sometimes. In other words, when installing on a desk or hanging from the ceiling, when opening to make it open, the former will cause the operation panel to fall, and the latter will lift the operation panel, so both will depend on the weight of the operation panel The direction in which the load is applied will change. Therefore, when the operation panel opens in the direction in which the load due to its own weight is applied, adding a resistance to hold the load to make it constant speed will slow down the rotating speed due to the resistance when hung from the ceiling. There was a problem that the feeling of discomfort in the speed was too great and the sense of quality was impaired.

本発明は、このような従来技術の問題点を解決することを課題とするものであり、操作パネルを開放姿勢にするため開く時（倒れる方向に回動させる時）、つまり操作パネルを自重による荷重が増す方向に回動させる時に、操作パネルが倒れ始めてから９０度近く倒れる終速時まで等速感をもたせるパネル開閉機構を提供することを目的とする。   An object of the present invention is to solve such problems of the prior art, and when the operation panel is opened to be in an open position (when the operation panel is rotated in a tilting direction), that is, the operation panel is driven by its own weight. It is an object of the present invention to provide a panel opening / closing mechanism that provides a constant speed feeling from the time when the operation panel starts to fall to the final speed at which it falls nearly 90 degrees when it is rotated in the direction in which the load increases.

また、操作パネルを自重による荷重が増す方向に回動させる時と、操作パネルを自重による荷重が働かない方向に回動させる時、等速感があって両者間での速度の違和感が少ないパネル開閉機構を提供することを目的とする。   Also, when the operation panel is rotated in the direction in which the load due to its own weight increases, and when the operation panel is rotated in the direction in which the load due to its own weight does not work, there is a feeling of constant speed and there is little discomfort in speed between the two An object is to provide an opening and closing mechanism.

本発明は、この目的を達成するため次のような構成を採用している。   The present invention employs the following configuration in order to achieve this object.

つまり、本発明のパネルの開閉機構は、バネの付勢力をパネルを倒す方向に作用させ、ダンパにより速度を制御しながらパネルを開閉する機器のパネル開閉機構において、パネルを自重による荷重が増す方向に回動させる時、該荷重を打ち消す方向に負荷を与える抵抗体を、パネルを支持する筐体に取り付けたものである。   In other words, the panel opening / closing mechanism of the present invention is a direction in which the load due to the weight of the panel increases in the panel opening / closing mechanism of the device that opens and closes the panel while controlling the speed by the damper by applying the biasing force of the spring in the direction of tilting the panel. A resistor that applies a load in a direction to cancel the load when attached to the housing is attached to a housing that supports the panel.

また、前記抵抗体を、前記パネルを支持する筐体に斜め方向にスライド自在に取り付け、パネルを自重による荷重が働かない方向に回動させる時、前記抵抗体が自重で斜め方向にスライドして前記負荷を与えない位置に移動するようにしたものである。   Further, when the resistor is slidably attached to a housing supporting the panel in an oblique direction and the panel is rotated in a direction in which a load due to its own weight does not work, the resistor is slid in an oblique direction by its own weight. It moves to a position where the load is not applied.

また、前記パネルを開閉するため、一端が枢軸を介して前記筐体にリンク結合され、他端側が前記パネルとリンク結合された第一のリンク部材と、一端が枢軸を介して前記筐体にリンク結合され、他端側が前記パネルとリンク結合された第二のリンク部材とを有してなるリンク機構とを備え、前記ダンパが筐体に取り付けられた回転ダンパであり、前記抵抗体がバネ力により外方に向けて押圧される移動子を備えるものであって、第一のリンク部材には枢軸と同軸上に該回転ダンパと噛み合う増速歯車を一体に形成するとともに、第二のリンク部材にはパネルを９０度近く開いた時に前記抵抗体の移動子に接触するように形成された突片を形成したものである。   In addition, in order to open and close the panel, one end is linked to the casing via a pivot, the other end is linked to the panel, and one end is linked to the casing via the pivot. A link mechanism having a second link member linked to the panel and having the other end linked to the panel, wherein the damper is a rotary damper attached to a housing, and the resistor is a spring The first link member is integrally formed with a speed increasing gear that meshes with the rotary damper on the first link member, and the second link. The member is formed with a projecting piece formed so as to come into contact with the mover of the resistor when the panel is opened nearly 90 degrees.

この構成によれば、下部を支軸として垂直に立設しているパネルを開放姿勢にするためパネルの自重による荷重が増す方向（倒れる方向）に回動させる時には、９０度近く倒れる時に荷重がＭＡＸになって、ダンパだけでは取りきれない回動速度の増加が発生するが、この荷重を打ち消す方向に負荷を与える抵抗体を備えているので、回動速度が増加することを防止して等速感をもたせたパネル開閉機構を提供することができる。   According to this configuration, when the panel that is erected vertically with the lower part as a support shaft is placed in an open posture, when the panel is rotated in the direction in which the load due to its own weight increases (the direction in which it falls), It becomes MAX, and the rotation speed that cannot be removed only by the damper is generated. However, since the resistor that applies the load in the direction to cancel this load is provided, the rotation speed is prevented from increasing. A panel opening / closing mechanism with a sense of speed can be provided.

さらに、下部を支軸として垂直に立設しているパネルを開放姿勢にするため自重による荷重が増す方向（倒れる方向）に回動させる時には、９０度近く倒れる時に荷重がＭＡＸになるが、この荷重がＭＡＸになる時、荷重を打ち消す方向に負荷を与える抵抗体が、筐体を反転させると自重で斜めにスライドして、負荷を与えない位置に移動して負荷を与えなくなるため、パネルを自重による荷重が働かない方向に回動させる時、終速時における回動速度が遅くなることを防止する。そのため、パネルを自重による荷重が増す方向に回動させる時と、パネルを自重による荷重が働かない方向に回動させる時、等速感があって両者間での速度の違和感が少ないパネル開閉機構を提供することができる。   Furthermore, when the panel standing upright with the lower part as a support shaft is placed in an open posture, when turning in the direction in which the load due to its own weight increases (falling direction), the load becomes MAX when it falls nearly 90 degrees. When the load becomes MAX, the resistor that applies the load in the direction that cancels the load slides diagonally with its own weight when the casing is reversed, and moves to a position where no load is applied, so that the load is not applied. When turning in a direction in which a load due to its own weight does not work, the turning speed at the final speed is prevented from slowing down. Therefore, when the panel is rotated in the direction in which the load due to its own weight increases, and when the panel is rotated in the direction in which the load due to its own weight does not work, the panel opening / closing mechanism has a constant speed feeling and less discomfort in speed between the two. Can be provided.

また、回転ダンパと増速歯車の組み合わせにより、ある程度速度を制御しながらパネルを開閉することができる。   Further, the combination of the rotary damper and the speed increasing gear can open and close the panel while controlling the speed to some extent.

次に本発明に係るパネル開閉機構の実施の形態（以下、実施例という）を図面に基づいて説明する。   Next, an embodiment (hereinafter referred to as an example) of a panel opening / closing mechanism according to the present invention will be described with reference to the drawings.

本発明実施例に係わるパネルの開閉機構の一実施例を、例えば電子機器のキャビネット（図示せず）の一側面に取着された操作パネルの扉開閉に使用する場合について説明する。図１に示したように、電子機器のキャビネット（図示せず）に取着するための筐体２に、下部を支軸３，４として垂直に立設している操作パネル５が操作面６の裏面７を表側になるように取り付けられている。通常は図３に示したように操作パネル５は閉じた状態である閉鎖姿勢に位置している。   An embodiment of a panel opening / closing mechanism according to the embodiment of the present invention will be described for use in opening / closing a door of an operation panel attached to one side of a cabinet (not shown) of an electronic device, for example. As shown in FIG. 1, an operation panel 5 is provided on a casing 2 for attaching to a cabinet (not shown) of an electronic device. The back surface 7 is attached so as to be on the front side. Usually, as shown in FIG. 3, the operation panel 5 is located in a closed posture in a closed state.

該操作パネル５を操作しやすい上方の位置まで移動するように開閉するため、一端が枢軸１４を介して前記筐体２にリンク結合され、他端側が前記操作パネル５の下部支軸３とリンク結合された第一のリンク部材１１と、第一のリンク部材１１の下方に配置され、一端が枢軸１５を介して前記筐体２にリンク結合され、他端側が前記操作パネル５の下部支軸４とリンク結合された第二のリンク部材１２とを有してなるリンク機構とを備えている。本実施例は、以下、このリンク運動により操作パネル５を開く場合について説明するが、本発明はリンク運動に限られるわけではなく、操作パネルが回転軸を支点として、装置本体の前面を覆う閉鎖姿勢と、９０度前方へ倒れる開放姿勢との間を回動できるように支持されているような回転運動により操作パネルを開く場合であっても適用できる。要は、操作パネルを自重による荷重が増す方向に回動させる時、後述するように操作パネル５の自重による荷重を打ち消す方向に負荷を与える抵抗体を筐体２に備えていれば良い。   In order to open and close the operation panel 5 so as to move to an upper position where it can be easily operated, one end is linked to the housing 2 via the pivot 14 and the other end is linked to the lower support shaft 3 of the operation panel 5. The first link member 11 coupled to the first link member 11 is disposed below the first link member 11, one end is linked to the housing 2 via the pivot 15, and the other end is the lower support shaft of the operation panel 5. 4 and a second link member 12 linked to the link mechanism. In this embodiment, the case where the operation panel 5 is opened by this link motion will be described below. However, the present invention is not limited to the link motion, and the operation panel closes the front surface of the apparatus main body with the rotation shaft as a fulcrum. The present invention can be applied even when the operation panel is opened by a rotational motion that is supported so as to be able to rotate between the posture and the open posture that falls forward 90 degrees. In short, when the operation panel is rotated in the direction in which the load due to its own weight is increased, the casing 2 may be provided with a resistor that applies a load in a direction to cancel the load due to the own weight of the operation panel 5 as described later.

前記筐体２には、ダンパである回転ダンパ８を取り付けるとともに、第一のリンク部材１１には枢軸１４と同軸上に該回転ダンパ８の歯車９と噛み合う扇形の増速歯車１０を一体に形成している。   A rotating damper 8 as a damper is attached to the casing 2, and a fan-shaped speed increasing gear 10 is formed integrally with the first link member 11 so as to be coaxial with the pivot 14 and mesh with the gear 9 of the rotating damper 8. is doing.

筐体２に軸支された第一リンク部材１１、第二リンク部材１２の各軸１４，１５に操作パネル５を開放側に押圧するねじりバネ（図示せず）を備えている。つまり、ねじりバネの付勢力をパネル５を倒す方向に作用させている。但し、筐体２には、操作パネル５を閉じた状態で操作パネル５に係合するロック装置（図示せず）を設けて、操作パネル５を閉じた状態では操作パネル５が開閉しない（倒れない）ように形成している。   A torsion spring (not shown) for pressing the operation panel 5 to the open side is provided on each of the shafts 14 and 15 of the first link member 11 and the second link member 12 that are pivotally supported by the housing 2. That is, the biasing force of the torsion spring is applied in the direction of tilting the panel 5. However, the casing 2 is provided with a lock device (not shown) that engages the operation panel 5 with the operation panel 5 closed, and the operation panel 5 does not open or close (fall down) when the operation panel 5 is closed. Not).

前記ダンパである回転ダンパ８により、ある程度速度を制御しながら操作パネル５を開閉することができる。さらに第一のリンク部材１１には回転ダンパ８の歯車９と噛み合う増速歯車１０を備えているので、より速度を均一に開閉することができる。しかし、９０度開く直前の終速に近い状態で操作パネル５の自重による荷重はＭＡＸに近くなっていて、前述の回転ダンパ８と増速歯車１０の組み合わせだけでは取りきれない速度の増加が発生する。   The operation panel 5 can be opened and closed while the speed is controlled to some extent by the rotary damper 8 which is the damper. Furthermore, since the first link member 11 includes the speed increasing gear 10 that meshes with the gear 9 of the rotary damper 8, the speed can be opened and closed more uniformly. However, the load due to the weight of the operation panel 5 is close to MAX in a state close to the final speed just before the opening of 90 degrees, and an increase in speed that cannot be obtained only by the combination of the rotary damper 8 and the speed increasing gear 10 occurs. To do.

この取りきれない速度の増加を防止するため抵抗体１７を筐体２に取り付けている。この抵抗体１７は開口部を有するケース１８内に底側にバネ（図示せず）を収納するとともにケース１８の開口部側に移動子１９をケース内を摺動可能でかつ先端部が開口部から外に向かって突出するように収納し、バネ力により移動子１９を外方に向けて押圧するように構成したものであって、第二リンク部材１２の軸部１５に操作パネル５と反対方向に向かって突片１６を延設するとともに、抵抗体１７を、操作パネル５を開放する時に開放し終わる直前に突片１６が移動子の先端に当接するように筐体２に取り付けている。つまり、操作パネル５の自重による荷重がＭＡＸ近くになった時、抵抗体１７が操作パネル５の自重による荷重を打ち消す負荷を与えて、速度が増加することを防止している。   The resistor 17 is attached to the housing 2 in order to prevent an increase in the speed that cannot be removed. The resistor 17 houses a spring (not shown) on the bottom side in a case 18 having an opening, and a slider 19 can be slid in the case 18 on the opening side of the case 18 and the tip is open. The movable member 19 is housed so as to protrude outward from the housing, and the moving element 19 is pressed outward by a spring force, and is opposite to the operation panel 5 on the shaft portion 15 of the second link member 12. In addition to extending the projecting piece 16 in the direction, the resistor 17 is attached to the housing 2 so that the projecting piece 16 comes into contact with the tip of the moving element immediately before the operation panel 5 is opened. . That is, when the load due to the own weight of the operation panel 5 becomes close to MAX, the resistor 17 applies a load that cancels the load due to the own weight of the operation panel 5 to prevent the speed from increasing.

さらに、この抵抗体１７は、ケース１８を筐体２に取り付けるためケース１８に一体に形成したフランジ２０に一対の平行な摺動溝２１を斜めに形成し、筐体２に前記フランジ２０の各摺動溝２１が嵌る一対の案内リブ２２を摺動溝２１に合わせて斜めに設けることにより、重力により、斜め方向に移動するように取り付けられている。従って、電子機器のキャビネットを天井から吊して設置（図１とは１８０度反転させて設置）する場合などのように操作パネル５を自重による荷重が働かない方向に回動させる時、前記抵抗体１７が自重で斜め方向にスライドして第二リンク部材１２の突片１６と移動子１９の先端が当接しない位置に移動するようにしている。なお、本実施例では、抵抗体１７はバネ力によるものを示したが、本発明はこれに限られるわけではなく、抵抗体１７は荷重変化を吸収する負荷を与えることができるものであればよいので、例えばバネ力に変えて、クッション、摩擦、オイルダンパ、グリースダンパ、エアダンパ等を適用することができる。   Further, the resistor 17 has a pair of parallel sliding grooves 21 formed obliquely on a flange 20 formed integrally with the case 18 in order to attach the case 18 to the housing 2. A pair of guide ribs 22 into which the sliding grooves 21 are fitted are provided obliquely in accordance with the sliding grooves 21 so that they are attached so as to move in an oblique direction by gravity. Therefore, when the operation panel 5 is rotated in a direction in which a load due to its own weight does not work, such as when the cabinet of the electronic device is hung from the ceiling (installed by reversing 180 degrees from FIG. 1), the resistance is reduced. The body 17 slides in an oblique direction by its own weight, and moves to a position where the projecting piece 16 of the second link member 12 and the tip of the moving element 19 do not contact each other. In the present embodiment, the resistor 17 is shown by a spring force. However, the present invention is not limited to this, and the resistor 17 can provide a load that absorbs a load change. Therefore, for example, a cushion, friction, an oil damper, a grease damper, an air damper, or the like can be applied instead of the spring force.

第一リンク部材１１と、第二リンク部材１２とは左右にそれぞれ設けられ、左右の第一リンク部材１１，１１を軸２４で連結して、左右の第一リンク部材１１，１１が連動するように形成することが望ましい。   The first link member 11 and the second link member 12 are provided on the left and right, respectively, and the left and right first link members 11 and 11 are connected by a shaft 24 so that the left and right first link members 11 and 11 are interlocked. It is desirable to form.

なお、操作パネル５が９０度開いた時点で第一リンク部材１１が他部材（例えば筐体２）に当接することにより、９０度開いた時点で停止するようにしている。この他部材が筐体２に設けたストッパ２３であっても良い。この９０度開いた位置を開放姿勢としている。   The first link member 11 comes into contact with another member (for example, the housing 2) when the operation panel 5 is opened 90 degrees, and is stopped when the operation panel 5 is opened 90 degrees. This other member may be the stopper 23 provided in the housing 2. The position opened 90 degrees is taken as the open posture.

このように構成されたパネル開閉機構は、筐体２に回転ダンパ８、第一リンク部材１１、第二リンク部材１２、抵抗体１７、操作パネル５が順次組み込まれてユニット化され、一体化した状態で取り扱われ、例えばプロジェクタのような電子機器に取着される。   In the panel opening / closing mechanism configured in this way, the rotary damper 8, the first link member 11, the second link member 12, the resistor 17, and the operation panel 5 are sequentially incorporated into the casing 2 and unitized. It is handled in a state and is attached to an electronic device such as a projector.

以下、使用方法について説明する。   The usage method will be described below.

まず、機器は机や床に設置する場合について説明する。パネル開閉機構１は、図１、図３に示したように、下部を支軸３，４として垂直に立設している操作パネル５を閉止位置に位置するように筐体２にロックした状態で電子機器（図示せず）に取り付けられている。   First, the case where an apparatus is installed on a desk or a floor is demonstrated. As shown in FIGS. 1 and 3, the panel opening / closing mechanism 1 is locked to the housing 2 so that the operation panel 5 standing vertically with the lower portion as the supporting shafts 3 and 4 is positioned at the closed position. And attached to an electronic device (not shown).

このロック状態から、ロック解除ボタン２３を押して操作パネル３と筐体２とのロックを解除すると、ねじりバネ（図示せず）の付勢力は、操作パネル５を開放姿勢に向けて倒す方向に作用するので、操作パネル５は回転ダンパ８により速度制御されつつ、第一リンク部材１１と第二リンク部材１２の協働作用で上方向に移動するように姿勢制御されつつ、図４に示したように開き始める。   When the lock between the operation panel 3 and the housing 2 is released by pressing the lock release button 23 from this locked state, the urging force of the torsion spring (not shown) acts in the direction of tilting the operation panel 5 toward the open posture. Therefore, while the speed of the operation panel 5 is controlled by the rotary damper 8, the posture of the operation panel 5 is controlled so as to move upward by the cooperative action of the first link member 11 and the second link member 12, as shown in FIG. Start to open.

さらに、操作パネル５は図５に示したように約４５度開いた状態を経て、開放姿勢に向けてさらに開いていくが、この時点で操作パネル５の自重による荷重はそれほど大きくなく、突片１６と移動子１９の先端は接触していない。また、増速歯車１０と該増速歯車１０と噛み合う回転ダンパ８の歯車９とのギア比を図４等に示したように大きくとる（図４では１０対１）ことにより初速から終速近くまで等速感を得ることができるようにしている。   Further, the operation panel 5 is opened about 45 degrees as shown in FIG. 5 and further opened toward the open posture. At this time, the load due to the weight of the operation panel 5 is not so large, and the protruding piece 16 and the tip of the moving element 19 are not in contact with each other. Further, by increasing the gear ratio between the speed increasing gear 10 and the gear 9 of the rotary damper 8 meshing with the speed increasing gear 10 as shown in FIG. 4 and the like (10 to 1 in FIG. 4), the initial speed is close to the final speed. It is possible to get a constant speed feeling.

さらに、図６に示したように操作パネル５が９０度開く直前の終速に近い状態を経て、さらに開いていくが、この時点で操作パネル５の自重による荷重はＭＡＸに近くなっていて、前述の回転ダンパ８と増速歯車１０の組み合わせだけでは取りきれない速度の増加が発生する。しかし図６の一部（回転ダンパ８等）を省略した図９に示すように突片１６と移動子１９の先端が接触して、該荷重を打ち消す方向に負荷を与えるので、終速での速度が増加することを防止できる。   Furthermore, as shown in FIG. 6, the operation panel 5 is further opened through a state close to the final speed immediately before opening 90 degrees. At this time, the load due to the weight of the operation panel 5 is close to MAX. An increase in speed that cannot be achieved only by the combination of the rotary damper 8 and the speed increasing gear 10 described above occurs. However, as shown in FIG. 9 in which a part of FIG. 6 (such as the rotary damper 8) is omitted, the projecting piece 16 and the tip of the moving element 19 come into contact with each other, and a load is applied in the direction to cancel the load. It is possible to prevent the speed from increasing.

やがて、図７に示すように操作パネル５が９０度開き終わった開放位置で停止する。前述のように操作パネル５が９０度開いた時点で、第一リンク部材１１が他部材（例えば筐体２）に当接して停止する。   Soon, as shown in FIG. 7, the operation panel 5 stops at the open position where the operation panel 5 has been opened 90 degrees. As described above, when the operation panel 5 is opened 90 degrees, the first link member 11 comes into contact with another member (for example, the housing 2) and stops.

次に、天井から吊して設置する場合について説明する。パネル開閉機構１は、図１０に示したように、上部を支軸３，４として垂直に立設している操作パネル５は筐体２にロックされた状態で電子機器（図示せず）に取り付けられている。つまり、机や床や設置した状態とは１８０度反転させて設置することになる。この電子機器を１８０度反転させて設置した状態で抵抗体１７は、重力により、斜め下方向にスライドする。従って、操作パネル５を自重による荷重が働かない方向に回動させる時、前記抵抗体１７が自重で斜め下方向にスライドして、図１６に示したように突片１６と移動子１９の先端が当接しない位置に移動するので、負荷を与えなくなる。   Next, the case where it installs by suspending from a ceiling is demonstrated. As shown in FIG. 10, the panel opening / closing mechanism 1 has an operation panel 5 erected vertically with the upper portions as support shafts 3 and 4, and is locked to the housing 2 in an electronic device (not shown). It is attached. That is, it is installed 180 degrees inverted from the desk, floor, or installed state. The resistor 17 slides diagonally downward due to gravity in a state in which the electronic device is inverted 180 degrees. Accordingly, when the operation panel 5 is rotated in a direction in which a load due to its own weight does not act, the resistor 17 slides obliquely downward with its own weight, and as shown in FIG. Since it moves to a position where it does not contact, no load is applied.

このロック状態から、ロック解除ボタン２３を押して操作パネル３と筐体２とのロックを解除すると、ねじりバネの付勢力は、操作パネル５を倒す方向に作用するので、操作パネル５は回転ダンパ８と増速歯車１０の組み合わせにより速度制御されつつ、第一リンク部材１１と第二リンク部材１２の協働作用で下方向に移動するように姿勢制御されつつ、図１２に示したように開き始める。   When the lock between the operation panel 3 and the housing 2 is released by pressing the lock release button 23 from this locked state, the urging force of the torsion spring acts in the direction of tilting the operation panel 5. As shown in FIG. 12, the speed is controlled by the combination of the speed increasing gear 10 and the posture is controlled so as to move downward by the cooperative action of the first link member 11 and the second link member 12, and as shown in FIG. .

さらに、図１３に示したように約４５度開いた状態を経て、さらに開いていくが、この時点で操作パネル５の自重による荷重はそれほど大きくなく、増速歯車１０と該増速歯車１０と噛み合う回転ダンパ８の歯車９とのギア比を図４等に示したように大きくとる（図４では１０対１）ことにより初速から終速まで等速感を得ることができるようにしている。   Further, as shown in FIG. 13, after the state of opening about 45 degrees, it further opens, but at this time, the load due to its own weight of the operation panel 5 is not so large, and the speed increasing gear 10 and the speed increasing gear 10 The gear ratio of the meshing rotating damper 8 with the gear 9 is set large as shown in FIG. 4 and the like (10 to 1 in FIG. 4) so that a constant speed feeling can be obtained from the initial speed to the final speed.

さらに、図１４に示したように９０度開く直前の終速に近い状態を経て、さらに開いていくが、図１４の一部（回転ダンパ８等）を省略した図１７に示すように突片１６と移動子１９の先端は当接しない位置に移動しているので、抵抗体１７が操作パネルに負荷を与えることがなく、終速での速度が遅くなることを防止できる。従って、操作パネル５を自重による荷重が増す方向に回動させる時と、操作パネル５を自重による荷重が働かない方向に回動させる時、等速感があって両者間での速度の違和感が少ないパネル開閉機構を提供することができる。   Furthermore, as shown in FIG. 14, after the state close to the final speed immediately before opening 90 degrees, it further opens, but as shown in FIG. 17, a part of FIG. 14 (rotating damper 8 etc.) is omitted. Since 16 and the tip of the moving element 19 are moved to a position where they do not contact, the resistor 17 does not apply a load to the operation panel, and it is possible to prevent the speed at the final speed from being lowered. Therefore, when the operation panel 5 is rotated in the direction in which the load due to its own weight is increased, and when the operation panel 5 is rotated in the direction in which the load due to its own weight does not work, there is a feeling of constant speed and there is a sense of incongruity between the two speeds. Fewer panel opening / closing mechanisms can be provided.

やがて、図１５に示すように操作パネル５が９０度開き終わった状態で、第一リンク部材１１が他部材（例えば筐体２）に当接して開放姿勢となって開閉が停止する。   Eventually, as shown in FIG. 15, in a state where the operation panel 5 has been opened 90 degrees, the first link member 11 comes into contact with another member (for example, the housing 2), becomes an open posture, and opens and closes.
