Description
【考案の詳細な説明】
８ミリ映画映写機には、フィルムスレッディングをスム
ーズに行なうためフィルム端を円弧状ないしやじり状に
カットするフィルム切断具を付加するのが普通であるが
、本考案はかかるフィルム切断具の形状に工夫をこらし
、切断具を映写角度調節にも役立てられるようにしたも
のである。[Detailed description of the invention] 8mm movie projectors are usually equipped with a film cutting tool that cuts the edges of the film into an arc or a serpentine shape in order to smoothly thread the film. The shape of the cutting tool has been devised so that it can also be used to adjust the projection angle.
以下本考案の一実施例を図に基いて説明する。An embodiment of the present invention will be described below with reference to the drawings.
フィルム切断具１は、合成樹脂製のベース２と、ベース
２に二本のねじ３で固定される鋼板製の切断刃４からな
る。The film cutting tool 1 consists of a base 2 made of synthetic resin and a cutting blade 4 made of a steel plate fixed to the base 2 with two screws 3.
切断刃４はねじどめ部５と、ねじどめ部５と平行に突出
した不動刃部６と、ねじどめ部５からある角度を持って
突出した可動刃部７の三部分からなる。The cutting blade 4 consists of three parts: a screwed part 5, an immovable blade part 6 that projects parallel to the screwed part 5, and a movable blade part 7 that projects from the screwed part 5 at a certain angle.
可動刃部７は二本の脚部８により不動刃部６をまたぐよ
うな形でねじどめ部５に連結しており、自由端には指掛
部９を有する。The movable blade part 7 is connected to the screw fastening part 5 by two legs 8 so as to straddle the fixed blade part 6, and has a finger hook part 9 at the free end.
不動刃部６と可動刃部７は互に組合わさる円弧状の刃縁
１０，１１を有しており、素材である鋼板の弾力に抗し
て可動刃部７を押下げると刃縁１０．１１の間でフィル
ムが剪断されるようになっている。The stationary blade part 6 and the movable blade part 7 have arc-shaped blade edges 10 and 11 that are combined with each other, and when the movable blade part 7 is pushed down against the elasticity of the steel plate that is the material, the blade edge 10. The film is sheared between 11 and 11.
他方ベース２はくさび形に成型され、くさび形をなす二
面のうち一方を接地面１２、他方は映写機支持面１３と
している。On the other hand, the base 2 is formed into a wedge shape, with one of the two wedge-shaped surfaces serving as a ground plane 12 and the other serving as a projector support surface 13.
接地面１２には凹所１４を形設しこの中に切断刃４を固
定する。A recess 14 is formed in the ground plane 12, and the cutting blade 4 is fixed therein.
凹所１４は接地面１２のみならずくさびの太い方の端面
においても開口部を有し、ここから、可動部７の指掛部
９が突出する。The recess 14 has an opening not only in the ground plane 12 but also in the thick end face of the wedge, from which the finger hook 9 of the movable part 7 projects.
凹所１４の内部には、ねじ３を螺合するポス１５の他、
不動刃部６の両側に突出するガイドリブ１６、不動刃部
６を支える枕リブ１７が形設され、その他適当数の補強
リブも形設されている。Inside the recess 14, in addition to the post 15 into which the screw 3 is screwed,
Guide ribs 16 protruding from both sides of the stationary blade part 6, pillow ribs 17 supporting the stationary blade part 6 are formed, and an appropriate number of reinforcing ribs are also formed.
他方映写機支持面１３には長手方向と直角に多数の溝１
８を設け、階段状の凹凸を構成している。On the other hand, the projector support surface 13 has a large number of grooves 1 perpendicular to the longitudinal direction.
8 to form step-like unevenness.
このような構成を有するフィルム切断具１は本来の役割
であるフィルム切断に用い得る他、第４図に示すように
映写機本体Ａの下に敷き込み、映写角度の調節、あるい
は設置面が傾斜している場合の本体Ａの安定化等に役立
てることができる。The film cutting tool 1 having such a configuration can not only be used for its original role of cutting film, but also be placed under the projector main body A as shown in Fig. 4 to adjust the projection angle or tilt the installation surface. This can be useful for stabilizing the main body A when
ベース２がくさび状であるから角度をきめ細かく調整で
きる。Since the base 2 is wedge-shaped, the angle can be finely adjusted.
また映写機支持面１３に階段状の凹凸を設けたことは、
映写機本体Ａとの間のスリップをなくすのに役立つ。Furthermore, the fact that the projector support surface 13 is provided with step-like unevenness,
This helps eliminate slippage between the projector body A and the projector body A.
以上のように本考案では切断刃を装着するフィルム切断
具のベースをくさび形に形成したから、これを下に敷い
て映写機の設置角度調整に用いることができ、くさび形
状のためきめ細かな調整が行なえると共に、フィルム切
断具という必需品であるため扱いが粗雑にならず、紛失
の懸念も少ないという利点を有する。As described above, in this invention, the base of the film cutting tool to which the cutting blade is attached is formed into a wedge shape, so it can be placed underneath and used to adjust the installation angle of the projector, and the wedge shape allows for fine adjustments. It has the advantage that it can be easily handled, and since it is a necessary item such as a film cutting tool, it will not be handled roughly and there is little fear of loss.
