（請求項６）
請求項６に記載の発明は、上記した請求項４記載の発明の特徴点に加え、以下の点を特徴とする。 (Claim 6)
The invention described in claim 6 has the following features in addition to the features of the invention described in claim 4 described above.

すなわち、前記上下動制限手段は、前記レバーの回動軸を上方から押さえこむストッパ部材と、前記ストッパ部材の上方向への移動を規制する止めネジと、を備えて構成され、前記止めネジを締め付けまたは緩めることで、前記ストッパ部材の上方向への移動を規制する位置が調節可能であることを特徴とする。 That is, the vertical movement restricting means includes a stopper member that presses the pivot shaft of the lever from above, and a set screw that restricts the upward movement of the stopper member. The position which controls the upward movement of the stopper member can be adjusted by tightening or loosening.

請求項１に記載の発明は上記の通りであり、定規挿入路の上部には、前記定規挿入路に挿入された平行定規に対して上方向から平行に当接する支持部材が上下動可能に配置され、前記支持部材の上部には、前記支持部材を下方に押圧可能な押圧手段が設けられている。このため、平行定規に対して支持部材が面接触して平行定規を固定するので、平行定規の取付バー上面に圧痕がつくのを有効に防止することができる。 The invention according to claim 1 is as described above, and a support member that abuts in parallel from above on a parallel ruler inserted in the ruler insertion path is disposed above the ruler insertion path so as to be movable up and down. The upper portion of the support member is provided with pressing means that can press the support member downward. For this reason, since the support member is in surface contact with the parallel ruler to fix the parallel ruler, it is possible to effectively prevent indentation on the upper surface of the mounting bar of the parallel ruler.

また、取付バーに圧痕がつかないため、支持部材が圧痕にならって支持されることがなく、取付バーを任意の位置で固定することができる。 Further, since the mounting bar is not indented, the support member is not supported following the indentation, and the mounting bar can be fixed at an arbitrary position.

また、請求項２に記載の発明は上記の通りであり、前記支持部材はベースに宙吊り状態で保持されており、前記定規挿入路の挿入側から見たときに、宙吊り状態の前記支持部材の下部が前記定規挿入路の内部に突出するとともに、この定規挿入路の内部に突出した前記支持部材の下部は、挿入方向に対して傾斜しているので、定規挿入路に平行定規を挿入すると、平行定規の先端が支持部材の傾斜面に当たって宙吊り状態の支持部材を上方に押し上げるようになっている。このため、平行定規の取付バーの板厚が薄ければ支持部材の押し上げが小さく、平行定規の取付バーの板厚が厚ければ支持部材の押し上げが大きくなるようになっている。このように平行定規の取付バーの板厚に応じた位置まで支持部材を押し上げた上で押圧手段によって支持部材を下方に押圧することで、様々な板厚の平行定規の取付バーを固定することができる。 Further, the invention according to claim 2 is as described above, wherein the support member is held in a suspended state on a base, and when viewed from the insertion side of the ruler insertion path, the support member is suspended in the suspended state. The lower part protrudes into the ruler insertion path, and the lower part of the support member protruding into the ruler insertion path is inclined with respect to the insertion direction, so when a parallel ruler is inserted into the ruler insertion path, The tip of the parallel ruler hits the inclined surface of the support member and pushes the suspended support member upward. For this reason, the push-up of the support member is small when the plate thickness of the mounting bar of the parallel ruler is thin, and the push-up of the support member is large when the plate thickness of the mounting bar of the parallel ruler is thick. In this way, the support member is pushed up to a position corresponding to the plate thickness of the parallel ruler mounting bar and then pressed downward by the pressing means, thereby fixing the parallel ruler mounting bar of various plate thicknesses. Can do.

また、請求項３に記載の発明は上記の通りであり、前記支持部材は、両端を上方に折り曲げた略コ字形の板金部材であるので、折り曲げ箇所によって自然に曲面を形成することができる。すなわち、特別な加工を要せずに、定規挿入路の内部に突出した傾斜面を形成することができる。 Further, the invention according to claim 3 is as described above, and the support member is a substantially U-shaped sheet metal member with both ends bent upward, so that a curved surface can be naturally formed by the bent portion. That is, it is possible to form an inclined surface protruding inside the ruler insertion path without requiring special processing.

また、請求項４に記載の発明は上記の通りであり、前記ベースに対して回動可能かつ上下動可能なレバーによって前記押圧手段を構成し、前記レバーは、前記支持部材を下方に押圧するための押圧カムを備え、前記レバーの上下動を制限するための上下動制限手段を設けた。このため、レバーが上下動することで様々な平行定規の取付バーの板厚に対応することができ、従来のレバー式の機構の弱点であった平行定規の取付バーの板厚に対応できないという問題を解決することができる。 Further, the invention according to claim 4 is as described above, and the pressing means is constituted by a lever that is rotatable and vertically movable with respect to the base, and the lever presses the support member downward. And a vertical movement limiting means for limiting the vertical movement of the lever. For this reason, the lever can be moved up and down to cope with the plate thickness of various parallel ruler mounting bars, and cannot cope with the plate thickness of the parallel ruler mounting bar, which was a weak point of the conventional lever type mechanism. The problem can be solved.

また、請求項５に記載の発明は上記の通りであり、前記レバーは、前記上下動制限手段として前記ベースに対して突っ張る上下動制限カムを備え、前記レバーを回動させたときに、前記上下動制限カムによって前記レバーの上下動が制限された後に、前記押圧カムによって前記支持部材を下方に押圧する。このため、レバーを回動させるだけでレバーの上下動が制限されるとともに、支持部材を押圧して平行定規を固定することができ、平行定規の固定を容易に行うことができる。 Further, the invention according to claim 5 is as described above, wherein the lever includes a vertical movement limiting cam that stretches against the base as the vertical movement limiting means, and when the lever is rotated, After the vertical movement restriction cam restricts the vertical movement of the lever, the support member is pressed downward by the pressing cam. For this reason, the vertical movement of the lever is limited only by rotating the lever, and the parallel ruler can be fixed by pressing the support member, and the parallel ruler can be easily fixed.

また、請求項６に記載の発明は上記の通りであり、前記上下動制限手段は、前記レバーの回動軸を上方から押さえこむストッパ部材と、前記ストッパ部材の上方向への移動を規制する止めネジと、を備えて構成され、前記止めネジを締め付けまたは緩めることで、前記ストッパ部材の上方向への移動を規制する位置が調節可能である。このため、止めネジを締め付けまたは緩めることで様々な平行定規の取付バーの板厚に対応することができる。 The invention according to claim 6 is as described above, and the vertical movement restricting means restricts upward movement of the stopper member and a stopper member that presses the pivot shaft of the lever from above. The position which regulates the upward movement of the stopper member can be adjusted by tightening or loosening the set screw. For this reason, it is possible to cope with the plate thicknesses of various parallel ruler mounting bars by tightening or loosening the set screws.

（第１の実施形態）
本発明の第１の実施形態について、図１〜７を参照しつつ説明する。 (First embodiment)
A first embodiment of the present invention will be described with reference to FIGS.

本実施形態に係る携帯用切断機１０は、図１に示すように、のこ刃１４を回転可能に支持する切断機本体１１の下部に、ベース２０が回動可能に取り付けられたものである。切断機本体１１のモータハウジング１２の内部にはモータが内蔵されており、このモータを作動させることでのこ刃１４が駆動され、被切断材を切断できるようにしたものである。 As shown in FIG. 1, the portable cutting machine 10 according to this embodiment has a base 20 rotatably attached to a lower part of a cutting machine body 11 that rotatably supports a saw blade 14. . A motor is built in the motor housing 12 of the cutting machine body 11, and the saw blade 14 is driven by operating this motor so that the material to be cut can be cut.

モータは、切断機本体１１後部のバッテリ装着部１７に着脱可能に設けられたバッテリ１８を駆動源として作動する。 The motor operates using a battery 18 detachably provided in the battery mounting portion 17 at the rear of the cutting machine body 11 as a drive source.

また、切断機本体１１の上部には、のこ刃１４の切断方向と略平行にグリップ１５が設けられ、このグリップ１５の内側に設けられたトリガ１６を引くことでモータが作動するようになっている。 Further, a grip 15 is provided on the upper portion of the cutting machine main body 11 substantially in parallel with the cutting direction of the saw blade 14, and the motor is activated by pulling a trigger 16 provided inside the grip 15. ing.

ベース２０は、切断機本体１１の下部に設けられて被切断材に当接する金属製の板状部材であり、貫通形成された刃口からのこ刃１４の一部を露出させることで、ベース２０の下方において被切断材を切断できるように形成されている。 The base 20 is a metal plate-like member that is provided in the lower part of the cutting machine main body 11 and abuts on the material to be cut. By exposing a part of the saw blade 14 from the blade hole formed through, the base 20 is exposed. It is formed so that the material to be cut can be cut below 20.

このベース２０の両側部には、被切断材を所定の寸法で平行に切断するための平行定規２５が装着可能となっている。具体的には、図１及び図２に示すように、ベース２０の両側部にそれぞれ２つずつ定規挿入路２０ａが開口しており、この定規挿入路２０ａに平行定規２５の取付バー２５ｂを挿入した上で、所定の装着機構で固定できるように形成されている。 A parallel ruler 25 for cutting the material to be cut in parallel with a predetermined dimension can be attached to both sides of the base 20. Specifically, as shown in FIGS. 1 and 2, two ruler insertion paths 20a are opened on each side of the base 20, and the mounting bar 25b of the parallel ruler 25 is inserted into the ruler insertion path 20a. In addition, it is formed so that it can be fixed by a predetermined mounting mechanism.

なお、平行定規２５は公知の形状であり、被切断材の側面に当接させる定規本体２５ａの両端に、ベース２０に取り付けるための取付バー２５ｂを設けたものである。 The parallel ruler 25 has a known shape, and is provided with attachment bars 25b for attachment to the base 20 at both ends of the ruler main body 25a to be brought into contact with the side surface of the material to be cut.

本実施形態に係る平行定規２５の装着機構は、図３に示すように、定規挿入路２０ａに挿入された平行定規２５に対して上方向から平行に当接する支持部材としての板金部材３０と、この板金部材３０を上下動可能にベース２０に取り付けるためのピン３１と、板金部材３０を下方に押圧可能な押圧手段としてのネジ部材３２と、ネジ部材３２を上方に付勢するバネ３３と、を備えている。 As shown in FIG. 3, the mounting mechanism of the parallel ruler 25 according to the present embodiment includes a sheet metal member 30 as a support member that abuts in parallel with the parallel ruler 25 inserted in the ruler insertion path 20a from above. A pin 31 for attaching the sheet metal member 30 to the base 20 so as to be movable up and down, a screw member 32 as a pressing means capable of pressing the sheet metal member 30 downward, and a spring 33 for biasing the screw member 32 upward; It has.

板金部材３０は、両端を上方に折り曲げた略コ字形の部材であり、略平行な側面部に長孔３０ａと切り欠き３０ｂとを設けたものである。長孔３０ａ及び切り欠き３０ｂにはピン３１が挿通され、このピン３１がベース２０のピン支持孔２０ｂに固定されることで、板金部材３０はベース２０に対して宙吊り状態で保持される。なお、長孔３０ａは上下に延びているため、板金部材３０は自重で吊下がった状態となっており、長孔３０ａの縦幅の分だけ上下に移動できるようになっている。 The sheet metal member 30 is a substantially U-shaped member whose both ends are bent upward, and is provided with a long hole 30a and a notch 30b in a substantially parallel side surface portion. A pin 31 is inserted into the long hole 30 a and the notch 30 b, and the pin 31 is fixed to the pin support hole 20 b of the base 20, whereby the sheet metal member 30 is held in a suspended state with respect to the base 20. Since the long hole 30a extends vertically, the sheet metal member 30 is suspended by its own weight and can move up and down by the vertical width of the long hole 30a.

また、この板金部材３０は、折り曲げ加工されることで曲折部３０ｃが自然に曲面を形成している。そして、ピン３１で板金部材３０を吊り下げたときに、この曲面を形成した曲折部３０ｃが定規挿入路２０ａの内部に突出するように配置される。詳しくは、図４及び図５に示すように、定規挿入路２０ａの挿入側から見たときに、宙吊り状態の板金部材３０下部の曲折部３０ｃが定規挿入路２０ａの内部に突出するとともに、この定規挿入路２０ａの内部に突出した曲折部３０ｃは曲面を形成することで挿入方向に対して拾い込み斜面を形成している。 Further, the bent portion 30c of the sheet metal member 30 is naturally curved by being bent. When the sheet metal member 30 is suspended by the pin 31, the bent portion 30c that forms this curved surface is disposed so as to protrude into the ruler insertion path 20a. Specifically, as shown in FIGS. 4 and 5, when viewed from the insertion side of the ruler insertion path 20a, the bent portion 30c at the bottom of the sheet metal member 30 in a suspended state protrudes into the ruler insertion path 20a. The bent portion 30c protruding into the ruler insertion path 20a forms a curved surface, thereby forming a sloped surface with respect to the insertion direction.

すなわち、定規挿入路２０ａの内部に突出した板金部材３０の下部には、挿入方向に対して傾斜した傾斜面と、挿入方向に対して水平な水平面とが形成され、水平面の挿入側端部が曲折することで円弧状の曲面が形成されている。 That is, an inclined surface that is inclined with respect to the insertion direction and a horizontal plane that is horizontal with respect to the insertion direction are formed at the lower portion of the sheet metal member 30 that protrudes into the ruler insertion path 20a. An arcuate curved surface is formed by bending.

ネジ部材３２は、上部のつまみ３２ａと下部の軸部３２ｂとからなる部材であり、板金部材３０の上部に配置される。このネジ部材３２の軸部３２ｂの周面には雄ネジが形成されているため、つまみ３２ａを回転操作することで軸部３２ｂがベース２０に対して螺合可能となっており、つまみ３２ａを回転させることでネジ部材３２が上下に進退するようになっている。ネジ部材３２の下端部は板金部材３０と当接可能な位置に配置されており、ネジ部材３２を締め付けることで板金部材３０を下方に押圧可能となっている。 The screw member 32 is a member composed of an upper knob 32 a and a lower shaft portion 32 b, and is disposed on the sheet metal member 30. Since a male screw is formed on the peripheral surface of the shaft portion 32b of the screw member 32, the shaft portion 32b can be screwed to the base 20 by rotating the knob 32a. The screw member 32 moves up and down by rotating. The lower end portion of the screw member 32 is disposed at a position where it can contact the sheet metal member 30, and the sheet metal member 30 can be pressed downward by tightening the screw member 32.

なお、このネジ部材３２はバネ３３によって上方に付勢されることによって、平行定規２５が無い状態（フリー状態）での振動によるネジ部材３２のゆるみを防止することができる。 The screw member 32 is urged upward by the spring 33, so that the screw member 32 can be prevented from loosening due to vibration in a state where there is no parallel ruler 25 (free state).

本実施形態に係る装着機構にを取り付ける際には、まず、図５に示すように、ネジ部材３２を緩めて板金部材３０が上方に自由に移動できるようにする。 When attaching to the mounting mechanism according to the present embodiment, first, as shown in FIG. 5, the screw member 32 is loosened so that the sheet metal member 30 can freely move upward.

この状態で平行定規２５の取付バー２５ｂを定規挿入路２０ａに挿入すると、図６に示すように、取付バー２５ｂの先端が板金部材３０の曲折部３０ｃに突き当たるが、曲折部３０ｃに拾い込み斜面が形成されているため、取付バー２５ｂが板金部材３０を持ち上げられてそのまま挿入される。 When the mounting bar 25b of the parallel ruler 25 is inserted into the ruler insertion path 20a in this state, as shown in FIG. 6, the tip of the mounting bar 25b hits the bent portion 30c of the sheet metal member 30, but the inclined surface is picked up by the bent portion 30c. Therefore, the mounting bar 25b lifts the sheet metal member 30 and is inserted as it is.

取付バー２５ｂを挿入し終わったら、図７に示すように、ネジ部材３２を締め付けて板金部材３０を下方に押圧する。これにより、板金部材３０の下方の接面が面接触で取付バー２５ｂを挟み込んで保持する。 When the insertion of the mounting bar 25b is completed, as shown in FIG. 7, the screw member 32 is tightened to press the sheet metal member 30 downward. Thereby, the lower contact surface of the sheet metal member 30 sandwiches and holds the mounting bar 25b by surface contact.

このような実施形態によれば、平行定規２５に対して板金部材３０が平行に面接触して平行定規２５を固定するので、平行定規２５の取付バー２５ｂ上面に圧痕がつくのを有効に防止することができる。 According to such an embodiment, since the sheet metal member 30 is in surface contact with the parallel ruler 25 in parallel to fix the parallel ruler 25, it is possible to effectively prevent indentation on the upper surface of the mounting bar 25b of the parallel ruler 25. can do.

また、板金部材３０はベース２０に宙吊り状態で保持されており、定規挿入路２０ａの挿入側から見たときに、宙吊り状態の板金部材３０の曲折部３０ｃが定規挿入路２０ａの内部に突出しているので、定規挿入路２０ａに平行定規２５を挿入したときに、平行定規２５の先端が板金部材３０の傾斜面（曲折部３０ｃ）に当たって宙吊り状態の板金部材３０を上方に押し上げるようになっている。このため、平行定規２５の取付バー２５ｂの板厚が薄ければ板金部材３０の押し上げが小さく、平行定規２５の取付バー２５ｂの板厚が厚ければ板金部材３０の押し上げが大きくなるようになっている。このように平行定規２５の取付バー２５ｂの板厚に応じた位置に押し上げられた板金部材３０をネジ部材３２によって下方に押圧することで、様々な板厚の平行定規２５の取付バー２５ｂを簡単に固定することができる。 Further, the sheet metal member 30 is held in a suspended state on the base 20, and when viewed from the insertion side of the ruler insertion path 20a, the bent portion 30c of the suspended sheet metal member 30 projects into the ruler insertion path 20a. Therefore, when the parallel ruler 25 is inserted into the ruler insertion path 20a, the tip of the parallel ruler 25 hits the inclined surface (bent portion 30c) of the sheet metal member 30, and the suspended sheet metal member 30 is pushed upward. . Therefore, if the plate thickness of the mounting bar 25b of the parallel ruler 25 is thin, the push-up of the sheet metal member 30 is small, and if the plate thickness of the mounting bar 25b of the parallel ruler 25 is thick, the push-up of the sheet metal member 30 is large. ing. Thus, by pressing the sheet metal member 30 pushed up to the position corresponding to the plate thickness of the mounting bar 25b of the parallel ruler 25 downward by the screw member 32, the mounting bar 25b of the parallel ruler 25 having various plate thicknesses can be easily obtained. Can be fixed to.

また、板金部材３０は、両端を上方に折り曲げた略コ字形であるので、折り曲げ箇所によって自然に曲面を形成することができる。すなわち、定規挿入路２０ａの内部に突出し、平行定規２５の取付バー２５ｂの先端部と接触した場合に、板金部材３０を押し上げるように誘導する傾斜面を特別な加工を要せずに形成することができる。 Moreover, since the sheet metal member 30 is substantially U-shaped with both ends bent upward, a curved surface can be naturally formed depending on the bent portion. That is, an inclined surface that protrudes into the ruler insertion path 20a and guides the sheet metal member 30 to be pushed up when it contacts the tip of the mounting bar 25b of the parallel ruler 25 is formed without requiring special processing. Can do.

（第２の実施形態）
本発明の第２の実施形態について、図８〜１２を参照しつつ説明する。 (Second Embodiment)
A second embodiment of the present invention will be described with reference to FIGS.

なお、本実施形態に係る携帯用切断機１０の基本的態様は第１の実施形態と同様であるので、重複した記載を避けて本実施形態の特徴点のみを説明する。 In addition, since the basic aspect of the portable cutting machine 10 which concerns on this embodiment is the same as that of 1st Embodiment, it avoids duplicate description and demonstrates only the feature point of this embodiment.

本実施形態の特徴点は、第１の実施形態の板金部材３０に代えて、図８に示すようなブロック部材３５を使用した点にある。 The feature of this embodiment is that a block member 35 as shown in FIG. 8 is used in place of the sheet metal member 30 of the first embodiment.

このブロック部材３５も、第１の実施形態の板金部材３０と同様に、定規挿入路２０ａに挿入された平行定規２５に対して上方向から平行に当接する支持部材としての役割を果たすものであり、両側に切り欠き３５ａを形成した略エ字形の金属製部材である。 Similarly to the sheet metal member 30 of the first embodiment, the block member 35 also serves as a support member that abuts in parallel with the parallel ruler 25 inserted into the ruler insertion path 20a from above. This is a substantially E-shaped metal member having notches 35a formed on both sides.

このブロック部材３５は、切り欠き３５ａにピン３１を係合させた状態でピン３１がベース２０のピン支持孔２０ｂに固定されることで、ベース２０に対して宙吊り状態で保持される。切り欠き３５ａはピン３１よりも上下に幅広に形成されているため、ブロック部材３５は自重で吊下がった状態となっており、切り欠き３５ａの幅の分だけ上下に移動できるようになっている。 The block member 35 is held in a suspended state with respect to the base 20 by fixing the pin 31 to the pin support hole 20b of the base 20 with the pin 31 engaged with the notch 35a. Since the cutout 35a is formed wider than the pin 31, the block member 35 is suspended by its own weight and can move up and down by the width of the cutout 35a. .

また、このブロック部材３５は、下端縁部が面取り加工されて傾斜面３５ｂを形成している。そして、ピン３１でブロック部材３５を吊り下げたときに、この傾斜面３５ｂが定規挿入路２０ａの内部に突出するようになっている。詳しくは、図９及び図１０に示すように、定規挿入路２０ａの挿入側から見たときに、宙吊り状態のブロック部材３５下部の傾斜面３５ｂが定規挿入路２０ａの内部に突出しており、この定規挿入路２０ａの内部に突出したブロック部材３５の下部が挿入方向に対して拾い込み斜面を形成している。 Further, the block member 35 has a lower end edge chamfered to form an inclined surface 35b. And when the block member 35 is suspended with the pin 31, this inclined surface 35b protrudes inside the ruler insertion path 20a. Specifically, as shown in FIGS. 9 and 10, when viewed from the insertion side of the ruler insertion path 20a, the inclined surface 35b below the suspended block member 35 protrudes into the ruler insertion path 20a. The lower part of the block member 35 protruding into the ruler insertion path 20a picks up the insertion direction and forms a slope.

本実施形態に係る装着機構に平行定規２５を取り付ける際には、まず、図１０に示すように、ネジ部材３２を緩めてブロック部材３５が上方に自由に移動できるようにする。 When attaching the parallel ruler 25 to the mounting mechanism according to the present embodiment, first, as shown in FIG. 10, the screw member 32 is loosened so that the block member 35 can freely move upward.

この状態で平行定規２５の取付バー２５ｂを定規挿入路２０ａに挿入すると、図１１に示すように、取付バー２５ｂの先端がブロック部材３５の傾斜面３５ｂに突き当たるが、傾斜面３５ｂが傾斜しているため、取付バー２５ｂがブロック部材３５を持ち上げてそのまま挿入される。 When the mounting bar 25b of the parallel ruler 25 is inserted into the ruler insertion path 20a in this state, the tip of the mounting bar 25b hits the inclined surface 35b of the block member 35 as shown in FIG. 11, but the inclined surface 35b is inclined. Therefore, the mounting bar 25b lifts the block member 35 and is inserted as it is.

取付バー２５ｂを挿入し終わったら、図１２に示すように、ネジ部材３２を締め付けてブロック部材３５を下方に押圧する。これにより、ブロック部材３５の下方の接面が面接触で取付バー２５ｂを挟み込んで保持する。 When the insertion of the mounting bar 25b is completed, as shown in FIG. 12, the screw member 32 is tightened to press the block member 35 downward. Thereby, the lower contact surface of the block member 35 sandwiches and holds the mounting bar 25b by surface contact.

このような実施形態によれば、平行定規２５に対してブロック部材３５が平行に面接触によって平行定規２５を固定するので、平行定規２５の取付バー２５ｂ上面に圧痕がつくのを有効に防止することができる。 According to such an embodiment, the block member 35 fixes the parallel ruler 25 by surface contact in parallel with the parallel ruler 25, so that it is possible to effectively prevent indentation on the upper surface of the mounting bar 25b of the parallel ruler 25. be able to.

また、ブロック部材３５はベース２０に宙吊り状態で保持されており、定規挿入路２０ａの挿入側から見たときに、宙吊り状態のブロック部材３５の傾斜面３５ｂが定規挿入路２０ａの内部に突出しているので、定規挿入路２０ａに平行定規２５を挿入すると、平行定規２５の先端がブロック部材３５の傾斜面３５ｂに当たって宙吊り状態のブロック部材３５を上方に押し上げるようになっている。このため、平行定規２５の取付バー２５ｂの板厚が薄ければブロック部材３５の押し上げが小さく、平行定規２５の取付バー２５ｂの板厚が厚ければブロック部材３５の押し上げが大きくなるようになっている。このように平行定規２５の取付バー２５ｂの板厚に応じた位置までブロック部材３５を押し上げた上でネジ部材３２によってブロック部材３５を下方に押圧することで、様々な板厚の平行定規２５の取付バー２５ｂを固定することができる。 Further, the block member 35 is held in a suspended state on the base 20, and when viewed from the insertion side of the ruler insertion path 20a, the inclined surface 35b of the block member 35 in a suspended state protrudes into the ruler insertion path 20a. Therefore, when the parallel ruler 25 is inserted into the ruler insertion path 20a, the tip of the parallel ruler 25 abuts against the inclined surface 35b of the block member 35 so as to push up the block member 35 suspended from the air. Therefore, when the plate thickness of the mounting bar 25b of the parallel ruler 25 is thin, the push-up of the block member 35 is small, and when the plate thickness of the mounting bar 25b of the parallel ruler 25 is thick, the push-up of the block member 35 is large. ing. In this way, the block member 35 is pushed up to the position corresponding to the plate thickness of the mounting bar 25b of the parallel ruler 25 and then pressed downward by the screw member 32, so that the parallel ruler 25 of various plate thicknesses is pressed. The mounting bar 25b can be fixed.

なお、本発明の第２の実施形態では両側に切り欠き３５ａを形成した略エ字形の金属製部材としているが、略直方体のブロック形状にして、切り欠き３５ａに相当する２個のピン溝を貫通形成した構成にしてもよい。（第３の実施形態）
本発明の第３の実施形態について、図１３〜１７を参照しつつ説明する。 In the second embodiment of the present invention, a substantially E-shaped metal member having notches 35a formed on both sides is formed. However, it is formed in a substantially rectangular parallelepiped block shape and has two pin grooves corresponding to the notches 35a. You may make it the structure penetrated. (Third embodiment)
A third embodiment of the present invention will be described with reference to FIGS.

本実施形態の特徴点は、第１の実施形態の装着機構に代えて、図１３に示すようなレバー式の装着機構を採用した点にある。 A characteristic point of this embodiment is that a lever-type mounting mechanism as shown in FIG. 13 is adopted instead of the mounting mechanism of the first embodiment.

本実施形態に係る平行定規２５の装着機構は、図１３に示すように、定規挿入路２０ａに挿入された平行定規２５に対して上方向から平行に当接する支持部材としての板金部材４０と、この板金部材４０を上下動可能にベース２０に取り付けるためのピン４１と、板金部材４０を下方に押圧可能な押圧手段としてのレバー４２と、を備えている。 As shown in FIG. 13, the mounting mechanism of the parallel ruler 25 according to the present embodiment includes a sheet metal member 40 as a support member that abuts in parallel from above on the parallel ruler 25 inserted into the ruler insertion path 20a. A pin 41 for attaching the sheet metal member 40 to the base 20 so as to be movable up and down, and a lever 42 as pressing means capable of pressing the sheet metal member 40 downward are provided.

板金部材４０は、両端を上方に折り曲げた略コ字形の部材であり、ピン４１の軸方向に貫通する長孔４０ａを備えている。この板金部材４０は、長孔４０ａにピン４１を貫通させた状態でピン４１がベース２０のピンガイド孔２０ｄに係合することで、ベース２０に対して宙吊り状態で保持される。長孔４０ａは上下に延びているため、板金部材４０は自重で吊下がった状態となっており、長孔４０ａの幅の分だけ上下に移動できるようになっている。 The sheet metal member 40 is a substantially U-shaped member with both ends bent upward, and includes a long hole 40 a penetrating in the axial direction of the pin 41. The sheet metal member 40 is held in a suspended state with respect to the base 20 by engaging the pin 41 with the pin guide hole 20d of the base 20 with the pin 41 passing through the long hole 40a. Since the long hole 40a extends vertically, the sheet metal member 40 is suspended by its own weight, and can move up and down by the width of the long hole 40a.

また、この板金部材４０は、折り曲げ加工されることで曲折部４０ｂが自然に曲面を形成している。そして、ピン４１で板金部材４０を吊り下げたときに、この曲面を形成した曲折部４０ｂが定規挿入路２０ａの内部に突出するようになっている。詳しくは、図１４に示すように、定規挿入路２０ａの挿入側から見たときに、宙吊り状態の板金部材４０下部の曲折部４０ｂが定規挿入路２０ａの内部に突出するとともに、この定規挿入路２０ａの内部に突出した曲折部４０ｂは曲面を形成することで挿入方向に対して傾斜している。 Further, the bent portion 40b of the sheet metal member 40 naturally forms a curved surface by being bent. When the sheet metal member 40 is suspended by the pin 41, the bent portion 40b that forms this curved surface protrudes into the ruler insertion path 20a. Specifically, as shown in FIG. 14, when viewed from the insertion side of the ruler insertion path 20a, the bent portion 40b at the bottom of the suspended sheet metal member 40 protrudes into the ruler insertion path 20a, and this ruler insertion path The bent portion 40b protruding inside 20a is inclined with respect to the insertion direction by forming a curved surface.

レバー４２は、操作部４２ａを操作することで回動するものであり、回動軸孔４２ｂを貫通する回動軸としてのピン４１を中心に回動可能となっている。このとき、ピン４１を支持するベース２０のピンガイド孔２０ｄは上下に延びる長孔で形成されているため、ピン４１はピンガイド孔２０ｄに沿って上下動可能となっている。このため、レバー４２もベース２０に対して上下動可能となっている。 The lever 42 is rotated by operating the operation portion 42a, and is rotatable about a pin 41 as a rotation shaft that penetrates the rotation shaft hole 42b. At this time, since the pin guide hole 20d of the base 20 that supports the pin 41 is formed as a long hole extending vertically, the pin 41 can move up and down along the pin guide hole 20d. For this reason, the lever 42 can also be moved up and down with respect to the base 20.

このレバー４２の回動軸孔４２ｂ付近には、偏心が異なる二種類のカムが設けられている。１つは、板金部材４０を下方に押圧するための押圧カム４２ｃであり、もう１つは、レバー４２の上下動を制限するための上下動制限手段としての上下動制限カム４２ｄである。 Two types of cams having different eccentricities are provided in the vicinity of the rotation shaft hole 42b of the lever 42. One is a pressing cam 42 c for pressing the sheet metal member 40 downward, and the other is a vertical movement limiting cam 42 d as a vertical movement limiting means for limiting the vertical movement of the lever 42.

押圧カム４２ｃは、レバー４２を回動させたときに、板金部材４０を下方に押圧するように作用するものである。 The pressing cam 42c acts to press the sheet metal member 40 downward when the lever 42 is rotated.

一方、上下動制限カム４２ｄは、レバー４２を回動させたときに、ベース２０に対して突っ張ることでレバー４２の上下動を制限するように作用する。詳しくは、図１３等に示すように、ベース２０の上下動制限カム４２ｄに臨む位置には縦溝状のカム係合部２０ｃが設けられており、レバー４２を回動させたときに、このカム係合部２０ｃの両側壁と上下動制限カム４２ｄとが係合してレバー４２の上下動が制限される。 On the other hand, the vertical movement limiting cam 42d acts so as to limit the vertical movement of the lever 42 by stretching against the base 20 when the lever 42 is rotated. Specifically, as shown in FIG. 13 and the like, a vertical groove-shaped cam engaging portion 20c is provided at a position facing the vertical movement limiting cam 42d of the base 20, and when the lever 42 is rotated, The vertical movement of the lever 42 is restricted by engaging both side walls of the cam engaging portion 20c with the vertical movement restricting cam 42d.

本実施形態に係る装着機構に平行定規２５を取り付ける際には、まず、図１５に示すように、レバー４２を解除方向に回動させる。これにより、板金部材４０及びレバー４２は上下動可能な状態となる。 When attaching the parallel ruler 25 to the mounting mechanism according to the present embodiment, first, as shown in FIG. 15, the lever 42 is rotated in the release direction. As a result, the sheet metal member 40 and the lever 42 can move up and down.

この状態で平行定規２５の取付バー２５ｂを定規挿入路２０ａに挿入すると、図１６に示すように、取付バー２５ｂの先端が板金部材４０の曲折部４０ｂに突き当たるが、曲折部４０ｂが傾斜しているため、取付バー２５ｂが板金部材４０を持ち上げてそのまま挿入される。このとき、板金部材４０を持ち上げられると同時に、板金部材４０の上に乗った状態のレバー４２も上方に持ち上げられる。 When the mounting bar 25b of the parallel ruler 25 is inserted into the ruler insertion path 20a in this state, as shown in FIG. 16, the tip of the mounting bar 25b hits the bent portion 40b of the sheet metal member 40, but the bent portion 40b is inclined. Therefore, the mounting bar 25b lifts the sheet metal member 40 and is inserted as it is. At this time, the sheet metal member 40 is lifted, and at the same time, the lever 42 on the sheet metal member 40 is also lifted upward.

取付バー２５ｂを挿入し終わったら、図１７に示すように、レバー４２を固定方向に回動させる。すると、まずカム係合部２０ｃの両側壁と上下動制限カム４２ｄとが係合してレバー４２の上下動が制限され、その後、押圧カム４２ｃが板金部材４０を下方に押圧する。これにより、板金部材４０の下方の接面が面接触で取付バー２５ｂを挟み込んで保持する。 When the mounting bar 25b has been inserted, the lever 42 is rotated in the fixing direction as shown in FIG. Then, both side walls of the cam engaging portion 20c and the vertical movement limiting cam 42d are engaged to limit the vertical movement of the lever 42, and then the pressing cam 42c presses the sheet metal member 40 downward. Thereby, the lower contact surface of the sheet metal member 40 sandwiches and holds the mounting bar 25b by surface contact.

このような実施形態によれば、平行定規２５に対して板金部材４０が平行に面接触して平行定規２５を固定するので、平行定規２５の取付バー２５ｂ上面に圧痕がつくのを有効に防止することができる。 According to such an embodiment, since the sheet metal member 40 is in surface contact with the parallel ruler 25 in parallel to fix the parallel ruler 25, it is possible to effectively prevent indentation on the upper surface of the mounting bar 25b of the parallel ruler 25. can do.

また、板金部材４０はベース２０に宙吊り状態で保持されており、定規挿入路２０ａの挿入側から見たときに、宙吊り状態の板金部材４０の曲折部４０ｂが定規挿入路２０ａの内部に突出しているので、定規挿入路２０ａに平行定規２５を挿入すると、平行定規２５の先端が板金部材４０の傾斜面（曲折部４０ｂ）に当たって宙吊り状態の板金部材４０を上方に押し上げるようになっている。このため、平行定規２５の取付バー２５ｂの板厚が薄ければ板金部材４０の押し上げが小さく、平行定規２５の取付バー２５ｂの板厚が厚ければ板金部材４０の押し上げが大きくなるようになっている。このように平行定規２５の取付バー２５ｂの板厚に応じた位置まで板金部材４０を押し上げた上でレバー４２によって板金部材４０を下方に押圧することで、様々な板厚の平行定規２５の取付バー２５ｂを固定することができる。 Further, the sheet metal member 40 is held in a suspended state on the base 20, and when viewed from the insertion side of the ruler insertion path 20a, the bent portion 40b of the suspended sheet metal member 40 protrudes into the ruler insertion path 20a. Therefore, when the parallel ruler 25 is inserted into the ruler insertion path 20a, the tip of the parallel ruler 25 abuts against the inclined surface (bent portion 40b) of the sheet metal member 40, and the suspended sheet metal member 40 is pushed upward. Therefore, if the plate thickness of the mounting bar 25b of the parallel ruler 25 is thin, the push-up of the sheet metal member 40 is small, and if the plate thickness of the mounting bar 25b of the parallel ruler 25 is thick, the push-up of the sheet metal member 40 is large. ing. In this way, the sheet metal member 40 is pushed up to the position corresponding to the sheet thickness of the mounting bar 25b of the parallel ruler 25 and then pressed downward by the lever 42, so that the parallel ruler 25 having various sheet thicknesses can be mounted. The bar 25b can be fixed.

特に、本実施形態のようなレバー式の機構においては平行定規２５の取付バー２５ｂの板厚の変化に対応しにくいという弱点があったが、本実施形態によれば、レバー４２が上下動することで様々な平行定規２５の取付バー２５ｂの板厚に対応することができる。 In particular, the lever type mechanism as in this embodiment has a weak point that it is difficult to cope with the change in the plate thickness of the mounting bar 25b of the parallel ruler 25. However, according to this embodiment, the lever 42 moves up and down. Thus, it is possible to correspond to the plate thickness of the mounting bar 25b of various parallel rulers 25.

しかも、レバー４２を回動させるだけでレバー４２の上下動が制限されるとともに、板金部材４０を押圧して平行定規２５を固定することができ、平行定規２５の固定を容易に行うことができる。 Moreover, the vertical movement of the lever 42 is limited only by rotating the lever 42, and the parallel ruler 25 can be fixed by pressing the sheet metal member 40, and the parallel ruler 25 can be easily fixed. .

また、板金部材４０は、両端を上方に折り曲げた略コ字形であるので、折り曲げ箇所によって自然に曲面を形成することができる。すなわち、特別な加工を要せずに、定規挿入路２０ａの内部に突出する部位に傾斜面を形成することができる。 Moreover, since the sheet metal member 40 is substantially U-shaped with both ends bent upward, a curved surface can be formed naturally depending on the bent portion. That is, an inclined surface can be formed at a portion protruding into the ruler insertion path 20a without requiring special processing.

（第４の実施形態）
本発明の第４の実施形態について、図１８〜２３を参照しつつ説明する。 (Fourth embodiment)
A fourth embodiment of the present invention will be described with reference to FIGS.

本実施形態の特徴点は、第１の実施形態の装着機構に代えて、図１８に示すようなレバー式の装着機構を採用した点にある。 A characteristic point of this embodiment is that a lever-type mounting mechanism as shown in FIG. 18 is adopted instead of the mounting mechanism of the first embodiment.

本実施形態に係る平行定規２５の装着機構は、図１８に示すように、定規挿入路２０ａに挿入された平行定規２５に対して上方向から平行に当接する支持部材としての板金部材４５と、この板金部材４５を上下動可能にベース２０に取り付けるためのピン４６と、板金部材４５を下方に押圧可能な押圧手段としてのレバー４７と、前記ピン４６を上方から押さえこむストッパ部材４８と、前記ストッパ部材４８の上方向への移動を規制する止めネジ４９と、を備えている。 As shown in FIG. 18, the mounting mechanism of the parallel ruler 25 according to the present embodiment includes a sheet metal member 45 as a support member that comes into contact with the parallel ruler 25 inserted in the ruler insertion path 20 a in parallel from above. A pin 46 for attaching the sheet metal member 45 to the base 20 so as to be movable up and down, a lever 47 as a pressing means capable of pressing the sheet metal member 45 downward, a stopper member 48 for pressing the pin 46 from above, And a set screw 49 for restricting the upward movement of the stopper member 48.

板金部材４５は、両端を上方に折り曲げた略コ字形の部材であり、ピン４１の軸方向に貫通する長孔４５ａ及び切り欠き４５ｂを備えている。この板金部材４０は、長孔４５ａ及び切り欠き４５ｂにピン４６を貫通させた状態でピン４６がベース２０のピンガイド孔２０ｄに係合することで、ベース２０に対して宙吊り状態で保持される。長孔４５ａは上下に延びているため、板金部材４５は自重で吊下がった状態となっており、長孔４５ａの幅の分だけ上下に移動できるようになっている。 The sheet metal member 45 is a substantially U-shaped member having both ends bent upward, and includes a long hole 45 a and a notch 45 b that penetrate the pin 41 in the axial direction. The sheet metal member 40 is held in a suspended state with respect to the base 20 by engaging the pin 46 with the pin guide hole 20d of the base 20 with the pin 46 passing through the long hole 45a and the notch 45b. . Since the long hole 45a extends vertically, the sheet metal member 45 is suspended by its own weight and can move up and down by the width of the long hole 45a.

また、この板金部材４５は、折り曲げ加工されることで曲折部４５ｃが自然に曲面を形成している。そして、ピン４６で板金部材４５を吊り下げたときに、この曲面を形成した曲折部４５ｃが定規挿入路２０ａの内部に突出するようになっている。詳しくは、図１９及び図２０に示すように、定規挿入路２０ａの挿入側から見たときに、宙吊り状態の板金部材４５下部の曲折部４５ｃが定規挿入路２０ａの内部に突出するとともに、この定規挿入路２０ａの内部に突出した曲折部４５ｃは曲面を形成することで挿入方向に対して傾斜している。 Further, the bent portion 45c of the sheet metal member 45 naturally forms a curved surface by being bent. When the sheet metal member 45 is suspended by the pin 46, the bent portion 45c that forms this curved surface protrudes into the ruler insertion path 20a. Specifically, as shown in FIGS. 19 and 20, when viewed from the insertion side of the ruler insertion path 20a, the bent portion 45c at the bottom of the sheet metal member 45 in a suspended state protrudes into the ruler insertion path 20a, and this The bent portion 45c protruding inside the ruler insertion path 20a is inclined with respect to the insertion direction by forming a curved surface.

レバー４７は、操作部４７ａを操作することで回動するものであり、回動軸孔４７ｂを貫通する回動軸としてのピン４６を中心に回動可能となっている。このとき、ピン４６を支持するベース２０のピンガイド孔２０ｄは上下に延びる長孔で形成されているため、ピン４６はピンガイド孔２０ｄに沿って上下動可能となっている。このため、レバー４７もベース２０に対して上下動可能となっている。 The lever 47 is rotated by operating the operation portion 47a, and is rotatable about a pin 46 as a rotation shaft that penetrates the rotation shaft hole 47b. At this time, since the pin guide hole 20d of the base 20 that supports the pin 46 is formed as a long hole extending vertically, the pin 46 can move up and down along the pin guide hole 20d. For this reason, the lever 47 can also be moved up and down with respect to the base 20.

このレバー４７の回動軸孔４７ｂ付近には、板金部材４５を下方に押圧するための押圧カム４７ｃが設けられている。この押圧カム４７ｃは、レバー４７を回動させたときに、板金部材４５を下方に押圧するように作用するものである。 In the vicinity of the rotation shaft hole 47b of the lever 47, a pressing cam 47c for pressing the sheet metal member 45 downward is provided. The pressing cam 47c acts to press the sheet metal member 45 downward when the lever 47 is rotated.

ストッパ部材４８及び止めネジ４９は、レバー４７の上下動を制限するための上下動制限手段として機能するものである。ストッパ部材４８は、略コ字形の部材であり、両端がピン４６と当接するように配置される。止めネジ４９は、ベース２０の止めネジ挿入部２０ｅに螺合して上下動するものであり、下端においてストッパ部材４８を抑えつけている。このため、止めネジ４９を締め付けることで、ストッパ部材４８の上方向への移動が規制され、ストッパ部材４８が上方からピン４６を押さえこむようになっている。言い換えると、止めネジ４９を締め付けまたは緩めることで、ストッパ部材４８及びピン４６の上方向への移動を規制する位置を調節可能となっている。 The stopper member 48 and the set screw 49 function as vertical movement limiting means for limiting the vertical movement of the lever 47. The stopper member 48 is a substantially U-shaped member and is arranged so that both ends thereof are in contact with the pin 46. The set screw 49 is screwed into the set screw insertion portion 20e of the base 20 and moves up and down, and holds the stopper member 48 at the lower end. For this reason, by tightening the set screw 49, the upward movement of the stopper member 48 is restricted, and the stopper member 48 presses the pin 46 from above. In other words, the position where the upward movement of the stopper member 48 and the pin 46 is regulated can be adjusted by tightening or loosening the set screw 49.

本実施形態に係る装着機構に平行定規２５を取り付ける際には、予め止めネジ４９を締め付けまたは緩めることで、平行定規２５の取付バー２５ｂの板厚に合うように、ストッパ部材４８及びピン４６の上方向への移動を規制する位置を調節する。そして、図２０に示すように、レバー４２を解除方向に回動させる。これにより、板金部材４５及びレバー４７は、ストッパ部材４８及び止めネジ４９によってピン４６の移動が規制される範囲において、上下動可能な状態となる。 When the parallel ruler 25 is attached to the mounting mechanism according to the present embodiment, the stopper member 48 and the pin 46 are fitted to the plate thickness of the mounting bar 25b of the parallel ruler 25 by tightening or loosening the set screw 49 in advance. Adjust the position that restricts the upward movement. Then, as shown in FIG. 20, the lever 42 is rotated in the release direction. As a result, the sheet metal member 45 and the lever 47 can move up and down within a range in which the movement of the pin 46 is restricted by the stopper member 48 and the set screw 49.

この状態で平行定規２５の取付バー２５ｂを定規挿入路２０ａに挿入すると、図２１に示すように、取付バー２５ｂの先端が板金部材４５の曲折部４５ｃに突き当たるが、曲折部４５ｃが傾斜しているため、取付バー２５ｂが板金部材４５を持ち上げてそのまま挿入される。このとき、板金部材４５を持ち上げられると同時に、板金部材４５の上に乗った状態のレバー４７も上方に持ち上げられる。 When the mounting bar 25b of the parallel ruler 25 is inserted into the ruler insertion path 20a in this state, the tip of the mounting bar 25b hits the bent portion 45c of the sheet metal member 45 as shown in FIG. 21, but the bent portion 45c is inclined. Therefore, the mounting bar 25b lifts the sheet metal member 45 and is inserted as it is. At this time, at the same time as the sheet metal member 45 is lifted, the lever 47 on the sheet metal member 45 is also lifted upward.

取付バー２５ｂを挿入し終わったら、図２２及び図２３に示すように、レバー４７を固定方向に回動させる。すると、押圧カム４７ｃが板金部材４５を下方に押圧する。これにより、板金部材４５の下方の接面が面接触で取付バー２５ｂを挟み込んで保持する。 When the mounting bar 25b has been inserted, the lever 47 is rotated in the fixing direction as shown in FIGS. Then, the pressing cam 47c presses the sheet metal member 45 downward. Thereby, the lower contact surface of the sheet metal member 45 sandwiches and holds the mounting bar 25b by surface contact.

このような実施形態によれば、平行定規２５に対して板金部材４５が平行に面接触して平行定規２５を固定するので、平行定規２５の取付バー２５ｂ上面に圧痕がつくのを有効に防止することができる。 According to such an embodiment, since the sheet metal member 45 is in surface contact with the parallel ruler 25 in parallel to fix the parallel ruler 25, it is possible to effectively prevent indentation on the upper surface of the mounting bar 25b of the parallel ruler 25. can do.

また、板金部材４５はベース２０に宙吊り状態で保持されており、定規挿入路２０ａの挿入側から見たときに、宙吊り状態の板金部材４５の曲折部４５ｃが定規挿入路２０ａの内部に突出しているので、定規挿入路２０ａに平行定規２５を挿入すると、平行定規２５の先端が板金部材４５の傾斜面（曲折部４５ｃ）に当たって宙吊り状態の板金部材４５を上方に押し上げるようになっている。このため、平行定規２５の取付バー２５ｂの板厚が薄ければ板金部材４５の押し上げが小さく、平行定規２５の取付バー２５ｂの板厚が厚ければ板金部材４５の押し上げが大きくなるようになっている。このように平行定規２５の取付バー２５ｂの板厚に応じた位置まで板金部材４５を押し上げた上でレバー４７によって板金部材４５を下方に押圧することで、様々な板厚の平行定規２５の取付バー２５ｂを固定することができる。 Further, the sheet metal member 45 is held in a suspended state on the base 20, and when viewed from the insertion side of the ruler insertion path 20a, the bent portion 45c of the suspended sheet metal member 45 projects into the ruler insertion path 20a. Therefore, when the parallel ruler 25 is inserted into the ruler insertion path 20a, the tip of the parallel ruler 25 abuts against the inclined surface (bent portion 45c) of the sheet metal member 45, and the suspended sheet metal member 45 is pushed upward. For this reason, if the plate thickness of the mounting bar 25b of the parallel ruler 25 is thin, the push-up of the sheet metal member 45 is small, and if the plate thickness of the mounting bar 25b of the parallel ruler 25 is thick, the push-up of the sheet metal member 45 becomes large. ing. In this way, the sheet metal member 45 is pushed up to a position corresponding to the sheet thickness of the mounting bar 25b of the parallel ruler 25, and the sheet metal member 45 is pressed downward by the lever 47, so that the parallel ruler 25 having various sheet thicknesses can be mounted. The bar 25b can be fixed.

特に、本実施形態のようなレバー式の機構においては平行定規２５の取付バー２５ｂの板厚の変化に対応しにくいという弱点があったが、本実施形態によれば、レバー４７が上下動することで様々な平行定規２５の取付バー２５ｂの板厚に対応することができる。 In particular, the lever type mechanism as in this embodiment has a weak point that it is difficult to cope with the change in the thickness of the mounting bar 25b of the parallel ruler 25. However, according to this embodiment, the lever 47 moves up and down. Thus, it is possible to correspond to the plate thickness of the mounting bar 25b of various parallel rulers 25.

また、板金部材４５は、両端を上方に折り曲げた略コ字形であるので、折り曲げ箇所によって自然に曲面を形成することができる。すなわち、特別な加工を要せずに、定規挿入路２０ａの内部に突出する部位に傾斜面を形成することができる。 Moreover, since the sheet metal member 45 is substantially U-shaped with both ends bent upward, a curved surface can be formed naturally depending on the bent portion. That is, an inclined surface can be formed at a portion protruding into the ruler insertion path 20a without requiring special processing.

なお、本実施形態では、定規挿入路２０ａの内部に突出した支持部材の折曲部を曲面形成としたが、取付バー２５ｂの先端部の拾いこみができる面取り斜面としてもよい。 In the present embodiment, the bent portion of the support member protruding into the ruler insertion path 20a is formed into a curved surface, but it may be a chamfered slope that can pick up the tip of the mounting bar 25b.
