前記のように構成されたミシンについて、次に作用を説
明する。The operation of the sewing machine constructed as described above will now be described.
さて、第3図は係止部体18の作用により蓋板14が針
板7の取付用開口8を閉鎖する位置に係止保持された状
態を示すものである。Now, FIG. 3 shows a state in which the cover plate 14 is locked and held in a position where the attachment opening 8 of the throat plate 7 is closed by the action of the locking member 18.
この状態においては上板5、針板I及び蓋板14により
それらの上面に広い加工品支持面が形成されているので

への浮上刃が付与され、前記係止部体18による蓋板1
4の係止が解除される。When opening the mounting opening 8 of the needle plate 7 from this state in order to attach the fabric edge cutting attachment, the operating section 22a of the operating section body 22 exposed on the front surface of the sewing machine bed 4 is pressed down. Then, when the operating body 22 is rotated counterclockwise from the state shown in FIG.
b comes into contact with the lower surface of the lid plate 14 in the closed position, giving the lid plate 14 an upward floating blade, and the locking part body 18 causes the lid plate 1 to
4 is released.
それにより、蓋板14が板ばね15の弾性作用により第

で、前記蓋板14の開放回動が阻止され、蓋板14は案
内部体9の傾斜案内面13aを含む平面内にほぼ位置さ
れる。As a result, the cover plate 14 is rotated clockwise to open from the closed position shown in FIG. 3 due to the elastic action of the leaf spring 15, and as shown in FIG. In a state in which the plate spring 15 is in contact with the opening edge and the engagement piece 15b of the leaf spring 15 is engaged with the inclined guide surface 13a of the guide body 9, the opening rotation of the cover plate 14 is prevented, and the cover plate 14 is not guided. It is located approximately within a plane that includes the inclined guide surface 13a of the part body 9.
その後、前記板はね15の反作用で蓋板14が第6図の

14が傾斜案内面13aに沿ってミシンベッド4内へ進
入移動される。Then, as shown in FIG. 7, the lower surface of the right end of the cover plate 14 comes into contact with the right end edge of the support plate part 8b in the mounting opening 8, and the engaging piece 15b of the leaf spring 15 comes into contact with the inclined part of the guide body 9. While in contact with the contact surface 11a or the lower surface of the mounting plate portion 9a,
The closing rotation of the cover plate 14 is prevented, and from this state, the cover plate 14 is again rotated clockwise to open due to the elastic action of the plate spring 150, and the engagement piece 15b of the plate spring 15 moves toward the inclined contact surface 1.
1a or the lower surface of the attachment plate portion 9a, the cover plate 14 is moved into the sewing machine bed 4 along the inclined guide surface 13a.
このように板ばね150作用により蓋板14が時計方向
及び反時計方向へ往復回動されながらミシンベッド4内

格納される。In this way, the cover plate 14 is sequentially moved into the sewing machine bed 4 while being reciprocated clockwise and counterclockwise by the action of the leaf spring 150, and the leaf spring 15 is moved into contact with the guide body 9 as shown in FIG. After separating from the engagement position, the movement inside the sewing machine bed 4 is restricted between the pair of regulating plates 12 along the inclined guide surface 13a of the guide body 9 due to the force and weight of the cover plate 14. It is automatically stored in a tilted position downward to the right.
そして、第2図に示すように蓋板14の左端下面に設け

ベッドの加工品支持面を十分に開放することができて、
布端切断用アタッチメントの装着、連結等を容易に行う
ことができるとともに、その開放状態で蓋板が縫製作業
等に支障を来たすおそれもない優れた効果を奏する。As detailed above, the present invention provides a cover plate for opening and closing an opening formed in a part of the workpiece support surface of a sewing machine bed.
By opening the lid, the long cover plate can be stored in an inclined position within the sewing machine bed, so even though there is no large space in the height direction within the sewing machine bed, the long cover plate can be stored in an inclined position within the sewing machine bed. The sewing machine bed can be easily and sufficiently stored, and the workpiece supporting surface of the sewing machine bed can be sufficiently opened by storing the long cover plate.
The fabric edge cutting attachment can be easily attached, connected, etc., and there is no fear that the lid plate will interfere with sewing work, etc. in the open state, and this is an excellent effect.
