上記特許文献１及び特許文献２に開示された患者頭部固定装置における側頭部押さえは、いずれも、術者若しくは補助者が患者の頭部を所定の位置に導入した後、適宜ハンドル操作等によりその位置調整をした上で左右の位置決めをするものであるが、この位置調整作業は少なからず煩わしさを伴うものであった。また、位置調整が不十分であったり、位置調整をし忘れたりすることがあり、その為、Ｘ線撮影が失敗し、再撮影によって患者に負担を強いることもあった。更には、調整機構が複雑であり、部品コスト、組立コストがかかるため、その改善が望まれていた。また、特許文献１の患者頭部固定装置における後頭部押さえ手段は、面ファスナーの係止、小孔と突起との係止、ハンドル操作による押え片の揺動等のように術者若しくは補助者に煩わしい作業が求められる上に、これらの作業が不十分になされると、Ｘ線の撮影精度が低下することにもなる。   As for the temporal pressing in the patient head fixing device disclosed in Patent Document 1 and Patent Document 2, the operator or an assistant introduces the patient's head to a predetermined position, and then appropriately operates the handle etc. However, this position adjustment work is not a little troublesome. In addition, the position adjustment may be insufficient, or the position adjustment may be forgotten. For this reason, X-ray imaging may fail, and the patient may be burdened by re-imaging. Furthermore, since the adjustment mechanism is complicated and requires parts cost and assembly cost, the improvement has been desired. Further, the occipital region pressing means in the patient head fixing device of Patent Document 1 can be used by an operator or an assistant such as hooking a hook-and-loop fastener, locking a small hole and a protrusion, and swinging a presser piece by a handle operation. In addition to requiring cumbersome operations, if these operations are insufficient, the X-ray imaging accuracy is also reduced.

本発明は、上記に鑑みて為されたものであり、より確実な患者頭部の位置付け固定が可能とされ、且つ操作性の良い医科歯科用Ｘ線撮影装置における患者頭部固定装置と、これを用いた医科歯科用Ｘ線撮影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, a patient head fixing device in a medical / dental X-ray imaging apparatus capable of more reliable positioning and fixing of the patient's head and good operability, and the same An object of the present invention is to provide a medical / dental X-ray imaging apparatus using the above.

第１の発明に係る医科歯科用Ｘ線撮影装置の患者頭部固定装置は、支持部と、該支持部に設けられ患者の両側頭部を押える一対の側頭部押え部と、該側頭部押え部を患者の側頭部に押当させ且つ押当を解除するよう動作させる為の作動機構部と、該作動機構部を押当方向に付勢する付勢手段と、作動機構部を該付勢手段の付勢力に抗して押当解除方向に操作する為の手動操作部とを備えたことを特徴とする。   A patient head fixing device of a medical / dental X-ray imaging apparatus according to a first aspect of the present invention includes a support portion, a pair of temporal head pressing portions that are provided on the support portion and press both sides of the patient, and the temporal head An actuating mechanism for pushing the pressing part against the patient's temporal region and releasing the pushing, an urging means for urging the actuating mechanism in the pushing direction, and an actuating mechanism. And a manual operation unit for operating in the pushing release direction against the urging force of the urging means.

本発明において、前記支持部が、チンレスト及び患者前頭部押え部の少なくともいずれかを更に有し、前記各側頭部押え部は、その先端又は先端近傍に患者の後頭部を押える後頭部押え片を備えているものとすることができる。この場合、前記後頭部押え片は、患者の側頭部より後頭部にかけての形状に略沿った円弧形状とされ、前記側頭部押え部に対して水平面域内で揺動可能に取付けられているものとすることができる。更に、この後頭部押え片は、その後頭部側が常時は互いに離反するよう弾性付勢されているものとすることができる。   In the present invention, the support portion further includes at least one of a chin rest and a patient frontal head pressing portion, and each of the temporal head pressing portions includes a rear head pressing piece for pressing the patient's rear head at or near the front end thereof. It can be provided. In this case, the occipital region pressing piece has an arc shape substantially along the shape from the patient's temporal region to the occipital region, and is attached to the temporal region pressing unit so as to be swingable within a horizontal plane area. can do. Further, the back head pressing piece can be elastically biased so that the back head side is always separated from each other.

また、第２の発明に係る医科歯科用Ｘ線撮影装置は、Ｘ線発生器と、Ｘ線検出器と、これらを対向させて支持する支持手段と、上記Ｘ線発生器及びＸ線検出器の間に患者の頭部を保持させる為の患者頭部固定装置とを備えた医科歯科用Ｘ線撮影装置であって、上記患者頭部固定装置が、上記のいずれかの患者頭部固定装置からなることを特徴とする。   A medical / dental X-ray imaging apparatus according to the second invention includes an X-ray generator, an X-ray detector, support means for supporting them in opposition to each other, and the X-ray generator and X-ray detector. A medical and dental X-ray imaging apparatus including a patient head fixing device for holding a patient's head between the patient head fixing device and the patient head fixing device. It is characterized by comprising.

上記第１の発明に係る患者頭部固定装置及び第２の発明に係る医科歯科用Ｘ線撮影装置によれば、側頭部押え部を患者の側頭部に押当させ且つ押当を解除するよう動作させる為の作動機構部が、常時は付勢手段によって押当方向に付勢されており、手動操作部によってこの付勢力に抗して押当解除が可能なように構成されているから、この手動操作部を操作するだけで患者頭部の撮影位置への導入が、患者に不快感や不安感を与えることなく円滑になされる。そして、操作部の操作を止め付勢手段による付勢力を解放すると、側頭部押え部は、付勢手段によって押当方向に作動し、患者頭部を両側部より挟むように押えてその位置付け固定が自動的且つ的確になされる。従って、従来のように位置調整が不十分な為に或いは位置調整のし忘れ等によるＸ線撮影の失敗を招く懸念がなくなる。   According to the patient head fixing device according to the first invention and the medical / dental X-ray imaging device according to the second invention, the temporal pressing part is pressed against the patient's temporal part and the pressing is released. The actuating mechanism for operating is normally urged in the pushing direction by the urging means, and the pushing operation can be released against the urging force by the manual operation unit. Therefore, the introduction of the patient's head into the photographing position can be smoothly performed only by operating the manual operation unit without giving the patient discomfort or anxiety. Then, when the operation of the operation unit is stopped and the urging force by the urging means is released, the temporal head pressing part is operated in the pressing direction by the urging means, and the patient's head is positioned so as to be sandwiched from both sides. Fixing is done automatically and accurately. Accordingly, there is no concern that the X-ray imaging may fail due to insufficient position adjustment as in the past or forgetting to adjust the position.

上記発明において、前記支持部が、チンレスト及び患者前頭部押え部の少なくともいずれかを更に有し、前記各側頭部押え部が、その先端又は先端近傍に患者の後頭部を押える後頭部押え片を備えているものとすれば、後頭部押え片と、チンレスト及び患者前頭部押え部の少なくともいずれかとにより、患者頭部を前後に挟むように固定することができるから、上記側頭部押え部による機能とも相俟って、患者頭部の位置付け固定がより的確になされる。特に、チンレストと後頭部押え片とを組合せた場合、患者頭部に対して前後・左右・上下方向から挟持する力が作用し、より安定した固定がなされる。   In the above invention, the support part further includes at least one of a chin rest and a patient frontal part pressing part, and each of the temporal part pressing parts includes a occipital part pressing piece for pressing the patient's occipital part at or near the front end thereof. If it is provided, it can be fixed so that the patient's head is sandwiched in the front and back by the back head pressing piece and at least one of the chin rest and the patient front head pressing portion. Combined with the function, the patient's head can be positioned and fixed more accurately. In particular, when a chin rest and a back head pressing piece are combined, a force for clamping the patient's head from the front, rear, left, and right directions acts, and more stable fixation is achieved.

この場合、前記後頭部押え片を、患者の側頭部より後頭部にかけての形状に略沿った円弧形状とし、前記側頭部押え部に対して水平面域内で揺動可能に取付け、更には、この後頭部押え片を、その後頭部側が常時は互いに離反するよう弾性付勢された状態とすれば、患者頭部の測定位置への導入及び測定位置からの退出誘導が円滑になされる。特に、後頭部押え片が上記のように円弧形状とされているので患者頭部の形状に適合し易く、しかも、その後頭部側が常時は互いに離反するよう弾性付勢されているので、患者導入の際の妨げとならず、患者導入後は後頭部押え片の側頭部側部分が患者頭部の側頭部に弾接して、上記適合がより確実なものとなる。   In this case, the occipital region pressing piece is formed in an arc shape substantially along the shape from the patient's temporal region to the occipital region, and is attached to the temporal region pressing part so as to be able to swing within a horizontal plane region. If the pressing piece is elastically biased so that the head side is always separated from each other thereafter, introduction of the patient's head into the measurement position and guidance of withdrawal from the measurement position are performed smoothly. In particular, since the back head pressing piece has an arc shape as described above, it is easy to adapt to the shape of the patient's head, and the back side of the head is always elastically biased away from each other. After the patient is introduced, the temporal portion of the occipital region pressing piece elastically contacts the temporal region of the patient's head, so that the above-mentioned adaptation is more reliable.

上記側頭部押え部１１，１１の先端部には、連結ピン１１ｂ，１１ｂを介し、後頭部押え片１４，１４が該連結ピン１１ｂ，１１ｂ回りに水平面域内で揺動可能に取付けられている。後頭部押え片１４，１４は、上記のように、患者の側頭部から後頭部にかけての形状に略沿った円弧形状とされ、その略中央部で上記連結ピン１１ｂ，１１ｂによって連結支持されている。上記弾性部材１４ａは、樹脂製薄板（厚さ０．５ｍｍ程度）等からなり、図４（ａ）（ｂ）に示すように、一端がビス１１ｃによって連結ピン１１ｂに固定され、他端側が後頭部押え片１４の内壁に弾接するよう屈曲した状態で組み込まれている。   Rear head pressing pieces 14 and 14 are attached to the front end portions of the side head pressing portions 11 and 11 via connecting pins 11b and 11b so as to be swingable around the connecting pins 11b and 11b in a horizontal plane area. As described above, the occipital region pressing pieces 14 and 14 have an arc shape that substantially conforms to the shape from the patient's temporal region to the occipital region, and are connected and supported by the connection pins 11b and 11b at substantially the center thereof. The elastic member 14a is made of a thin resin plate (thickness of about 0.5 mm) or the like, and as shown in FIGS. 4 (a) and 4 (b), one end is fixed to the connecting pin 11b by a screw 11c and the other end side is the back of the head. It is assembled in a bent state so as to elastically contact the inner wall of the presser piece 14.

上記のような構成の患者頭部固定装置９による患者頭部の位置付け固定要領について、図５（ａ）（ｂ）をも参照して説明する。図３において操作ノブ１９を矢印ｂ方向に回動操作すると、ピニオンギヤ１９ａとラック１８ａとの噛合によって、作動板１８は引張ばね１７の引張弾力に抗して反ａ方向に摺動する。この作動板１８の反ａ方向への摺動に伴い、ガイド溝１８ｂ、１８ｂ内をガイドピン２１ａ，２１ａが相対摺接する。この相対摺接によって、作動板１８の前後方向の動作が支持基板２１，２１の横方向への運動に変換され、支持基板２１，２１がスライド棒２０，２０に沿って互いに離反する方向に摺動する。図３及び図５（ａ）は、支持基板２１，２１が最も離反した状態であって、側頭部押え部１１，１１の間隔が最も大きく開いた状態となっていることを示している。また、後頭部押え片１４，１４は、上記弾性部材１４ａ，１４ａの復元弾力により、その後頭部側１４Ａ，１４Ａ（連結ピン１１ｂによる支持部より先側）が互いに離反し、大きく開いた状態となっている。   The procedure for positioning and fixing the patient's head by the patient's head fixing device 9 configured as described above will be described with reference to FIGS. 5 (a) and 5 (b). In FIG. 3, when the operation knob 19 is rotated in the direction of arrow b, the operating plate 18 slides in the anti-a direction against the tensile elasticity of the tension spring 17 due to the engagement between the pinion gear 19 a and the rack 18 a. As the operating plate 18 slides in the direction opposite to the a-direction, the guide pins 21a and 21a are in relative sliding contact with the guide grooves 18b and 18b. By this relative sliding contact, the longitudinal movement of the operating plate 18 is converted into the lateral movement of the support substrates 21, 21, and the support substrates 21, 21 are slid along the slide bars 20, 20 in directions away from each other. Move. 3 and 5A show that the support substrates 21 and 21 are most distant from each other, and the space between the temporal pressing portions 11 and 11 is the largest. Further, the back head pressing pieces 14 and 14 are in a state of being largely opened due to the back head sides 14A and 14A (front side of the support portion by the connecting pin 11b) being separated from each other by the restoring elasticity of the elastic members 14a and 14a. Yes.

この状態で、図５（ａ）に示すよう、患者Ｐの頭部を白抜矢示のように開いた側頭部押え部１１，１１間に導入し、患者Ｐの顎をチンレスト１２上に載せ、更には前頭部押え部１３（図１参照）に患者Ｐの前頭部を宛がった上で、操作ノブ１９の操作力を緩め、引張ばね１７の復元弾力により作動板１８を矢印ａ方向（図３参照）へ後退させる。この作動板１８の後退動作に伴い、ガイドピン２１ａ，２１ａが上記とは逆の方向にガイド溝１８ｂ，１８ｂを摺接し、これに伴い支持基板２１，２１はスライド棒２０，２０に沿って互いに接近する方向に摺動する。従って、側頭部押え部１１，１１も患者Ｐの両側頭部に押当する方向に動作し、押当がなされた時点で操作ノブ１７を手離すと側頭部押え部１１，１１が患者Ｐの両側頭部に弾性押当し、患者頭部の左右の位置付け固定がなされる。このように患者頭部の左右の位置付け固定は、操作ノブ１９を回動操作した後に手離すだけで簡易且つ的確になされる。   In this state, as shown in FIG. 5 (a), the head of the patient P is introduced between the temporal pressing portions 11 and 11 opened as indicated by white arrows, and the jaw of the patient P is placed on the chin rest 12. Further, after the frontal head of the patient P is applied to the forehead presser 13 (see FIG. 1), the operating force of the operating knob 19 is loosened, and the operating plate 18 is moved by the restoring elasticity of the tension spring 17. Retract in the direction of arrow a (see FIG. 3). As the operating plate 18 moves backward, the guide pins 21a and 21a slide in contact with the guide grooves 18b and 18b in the opposite direction, and the support substrates 21 and 21 move along the slide bars 20 and 20 with each other. Slide in the approaching direction. Accordingly, the temporal pressing portions 11 and 11 also operate in the direction of pressing against both heads of the patient P, and when the operation knob 17 is released when the pressing is performed, the temporal pressing portions 11 and 11 The left and right positioning of the patient's head is fixed by elastic pressing against both sides of P. In this way, the right and left positioning and fixing of the patient's head can be simply and accurately performed by simply releasing the operation knob 19 after turning it.

上記患者Ｐの導入の際、後頭部押え片１４，１４の側頭部側１４Ｂ、１４Ｂ（連結ピン１１ｂによる支持部より後側）が互いに接近した状態となっているから、患者Ｐの側頭部によって側頭部側１４Ｂ、１４Ｂが押し広げられ、これにより連結ピン１１ｂ，１１ｂを支点として後頭部側１４Ａ、１４Ａが弾性部材１４ａ，１４ａの屈曲変形を伴い、閉じるように患者Ｐの後頭部にフィットした状態で当接し、図５（ｂ）に示す状態となる。従って、後頭部押え片１４，１４による患者Ｐの後頭部の当接と、前記チンレスト１２及び前頭部押え部１３に対する位置付けとにより、患者頭部の前後方向及び上下方向の位置付けも的確になされる。この状態で旋回アーム６を旋回作動させ、また必要に応じて水平面域での２次元移動を組み合わせ、Ｘ線発生器７及びＸ線検出器８を作動させることによって、患者Ｐの全顎パノラマ撮影やＣＴ撮影等の目的のＸ線撮影を精度良く実施することができる。   When the patient P is introduced, the temporal regions 14B and 14B of the back head pressing pieces 14 and 14 (the rear side from the support portion by the connecting pin 11b) are close to each other. The side heads 14B and 14B are pushed and spread by this, and the back heads 14A and 14A are fitted to the back of the head of the patient P so as to be closed with the bending deformation of the elastic members 14a and 14a with the connecting pins 11b and 11b as fulcrums. It contacts in a state and it will be in the state shown in FIG.5 (b). Accordingly, the patient head is positioned in the front-rear direction and the vertical direction by the contact of the back of the patient P with the back head pressing pieces 14 and 14 and the positioning with respect to the chin rest 12 and the front head pressing portion 13. In this state, the swivel arm 6 is swung, and if necessary, two-dimensional movement in a horizontal plane area is combined, and the X-ray generator 7 and the X-ray detector 8 are operated, so that panoramic imaging of the patient P is performed. And X-ray imaging for the purpose such as CT imaging can be performed with high accuracy.

撮影終了後、患者Ｐを退出させる際は、操作ノブ１９を上記と同様矢印ｂ方向に回動操作し、側頭部押え部１１，１１を患者Ｐの側頭部から離して押当を解除させると、後頭部押え片１４，１４も患者Ｐの頭部から離れる。これにより、後頭部押え片１４，１４が、屈曲された弾性部材１４ａ，１４ａの復元弾力により、図４（ｂ）の矢印ｃ方向に旋回揺動して図４（ａ）の状態に戻る。従って、図３或いは図５（ａ）に示すように側頭部押え部１１，１１が開き、後頭部押え片１４，１４の後頭部側１４Ａ，１４Ａも開いた状態とされるから、患者Ｐは何ら不快感を伴うことなく撮影位置から退出することができる。   When the patient P is withdrawn after the photographing is finished, the operation knob 19 is rotated in the direction of the arrow b in the same manner as described above, and the temporal pressing portions 11 and 11 are separated from the temporal region of the patient P to release the pressing. Then, the back head pressing pieces 14 and 14 are also separated from the patient P's head. As a result, the back head pressing pieces 14 and 14 are swung in the direction of arrow c in FIG. 4B and returned to the state in FIG. 4A due to the restoring elasticity of the bent elastic members 14a and 14a. Accordingly, as shown in FIG. 3 or FIG. 5 (a), the temporal head pressing portions 11 and 11 are opened, and the occipital side pressing pieces 14 and 14 are also opened. It is possible to leave the shooting position without causing discomfort.

図６は、患者頭部固定装置９の他の実施形態を示し、側頭部押え部１１，１１を患者の側頭部に押当させ且つ押当を解除させる為の作動機構部１６を、押当方向に付勢する為の付勢手段が上記実施形態と異なる。即ち、この場合の付勢手段１７は、作動板１８の後端に連結されたワイヤ（或いは紐）１７ａと、滑車１７ｂを介して該ワイヤ１７ａの先端に吊持された錘１７ｃとよりなる。滑車１７ｂ及び錘１７ｃは、支柱２内に設けられる。錘１７ｃによって、作動板１８には常時矢印ａ方向に付勢力が付加される。その他の構成は上記と同様とされるから、操作ノブ１９の矢印ｂ方向への回動操作により上記同様作動板１８の前方への摺動がなされ、側頭部押え部１１，１１及び後頭部押え片１４，１４は上記と同様に動作して、患者頭部の導入・退出が可能とされる。そして、操作ノブ１９の操作停止と手離しにより患者頭部の位置付け固定が上記同様に的確になされる。尚、上記実施形態と共通するその他の部分には同一の符号を付し、その説明は割愛する。   FIG. 6 shows another embodiment of the patient head fixing device 9, and an operating mechanism portion 16 for pressing the temporal pressing portions 11, 11 against the patient's temporal region and releasing the pressing, The biasing means for biasing in the pushing direction is different from that in the above embodiment. That is, the urging means 17 in this case includes a wire (or string) 17a connected to the rear end of the operating plate 18, and a weight 17c suspended from the tip of the wire 17a via a pulley 17b. The pulley 17 b and the weight 17 c are provided in the column 2. The urging force is always applied to the operation plate 18 in the direction of the arrow a by the weight 17c. Since the other configuration is the same as described above, the operation plate 18 is slid forward by the rotation operation of the operation knob 19 in the direction of the arrow b, and the side head pressing portions 11 and 11 and the back head pressing are performed. The pieces 14 and 14 operate in the same manner as described above, so that the patient's head can be introduced and withdrawn. Then, the positioning and fixing of the patient's head is accurately performed as described above by stopping the operation knob 19 and releasing it. In addition, the same code | symbol is attached | subjected to the other part which is common in the said embodiment, and the description is omitted.

図７は、患者頭部固定装置９の更に他の実施形態を示し、側頭部押え部１１，１１を患者の側頭部に押当させ且つ押当を解除させる為の作動機構部１６を、押当方向に付勢する為の付勢手段が上記実施形態と異なる。即ち、この場合の付勢手段１７は、支持基板２１，２１間に張架された引張ばねによりなり、この引張ばね１７によって支持基板２１，２１は互いに接近する方向（矢印ｄ方向）に弾力付勢されている。その他の構成は上記と同様であり、従って、操作ノブ１９の矢印ｂ方向への回動操作により作動板１８の前方への摺動がなされ、支持基板２１，２１が上記付勢弾力に抗して互いに離反するよう動作する。これにより側頭部押え部１１，１１及び後頭部押え片１４，１４が上記と同様に動作して、患者頭部の導入・退出が可能とされる。また、操作ノブ１９の操作停止と手離しにより、上記同様患者頭部の位置付け固定が的確になされる。尚、上記実施形態と共通するその他の部分には同一の符号を付し、ここでもその説明は割愛する。   FIG. 7 shows still another embodiment of the patient head fixing device 9, and an operation mechanism portion 16 for pressing the temporal pressing portions 11, 11 against the temporal region of the patient and releasing the pressing. The urging means for urging in the pushing direction is different from the above embodiment. In other words, the urging means 17 in this case is constituted by a tension spring stretched between the support substrates 21 and 21, and the support substrates 21 and 21 are elastically applied by the tension spring 17 in a direction in which they approach each other (arrow d direction). It is energized. The rest of the configuration is the same as described above. Therefore, the operating plate 18 is slid forward by the turning operation of the operation knob 19 in the direction of the arrow b, and the support substrates 21 and 21 resist the biasing elasticity. To move away from each other. As a result, the temporal head pressing portions 11 and 11 and the back head pressing pieces 14 and 14 operate in the same manner as described above, so that the patient's head can be introduced and withdrawn. Further, the positioning and fixing of the patient's head can be accurately performed by stopping and releasing the operation knob 19 as described above. In addition, the same code | symbol is attached | subjected to the other part which is common in the said embodiment, and the description is omitted here.

尚、セファロ撮影用ユニット５の患者頭部保持部５ｂにも上記患者頭部固定装置９を適用することができる。また、図１ではチンレスト１２及び前頭部押え部１３を備えた例を示しているが、これらはどちらか一方のみでも良く、またこれらの代わりに鼻下点を押さえる構成を採用しても良い。更に、側頭部押え部１１，１１は、旋回アーム６の旋回基部を支持部として、下方に延びるよう構成しても良い。加えて、付勢手段１７としては、上記実施形態以外に、例えば、支持基板２１，２１とベースプレート１０ａの側壁との間に一対の圧縮ばねを介在させること、支持基板２１，２１間を紐等で繋ぎその中央に錘を取付けること、更にはばね以外の弾性体により上記と同様の付勢弾力を付加させること等、種々の手段が採用可能である。また、付勢手段１７の付勢力に抗して側頭部押え部１１を互いに離反させる操作部として、操作ノブ１９を例に上記実施形態を説明したが、操作ノブに限らず、例えば操作スイッチでモータ（いずれも不図示）を駆動し、そのモータの駆動によって側頭部押え部１１を互いに離反させるといった構成も採用可能であり、このような構成の場合、操作スイッチは手押し式とすることもでき、足踏み式フートスイッチとすることもできる。   The patient head fixing device 9 can also be applied to the patient head holding part 5b of the cephalo imaging unit 5. Moreover, although the example provided with the chin rest 12 and the frontal part pressing part 13 is shown in FIG. 1, these may be only one, and the structure which presses down a nose point may be employ | adopted instead of these. . Further, the side head pressing portions 11 and 11 may be configured to extend downward with the turning base portion of the turning arm 6 as a support portion. In addition, as the biasing means 17, in addition to the above embodiment, for example, a pair of compression springs are interposed between the support substrates 21 and 21 and the side wall of the base plate 10 a, and a string or the like is provided between the support substrates 21 and 21. Various means can be employed, such as connecting with a weight and attaching a weight to the center thereof, and applying an urging elastic force similar to the above by an elastic body other than a spring. Further, the above embodiment has been described by taking the operation knob 19 as an example of the operation unit that separates the temporal pressing portions 11 from each other against the urging force of the urging means 17, but is not limited to the operation knob. It is also possible to employ a configuration in which a motor (none of which is not shown) is driven and the temporal pressing portions 11 are separated from each other by driving the motor. In such a configuration, the operation switch is a hand-push type. It can also be a foot-operated foot switch.
