As is apparent from FIGS. 3 and 11, when the screw is pushed by the driver bit, the door can open to both sides to allow the screw to pass through, and after passing through the screw, the spring can return to a predetermined position. it can.

Next, the operation of the screw driving device of the present invention will be described. First, after opening the lid 5b of the magazine 5 removed from the sliding member 4, the swiveling lever 41 is swung clockwise against the spring 44 as seen in FIG. 7, and its tip 41a is locked by the locking member 49. The turning lever 41 is locked by engaging with the protruding portion 51 (the position indicated by the solid line in FIG. 7). After that, a large number of screws of a predetermined size are loaded in the screw guide groove 20 and the branch screw guide groove 21 with the screw parts facing downward. Branch screw guide groove 21
In, the heads of the screws are arranged adjacent to each other. Then, when the lid 5b is closed, the inner surface of the lid 5b pushes the protrusion 53 at the top of the lock member 49, so that the lock protrusion portion 51 of the lock member 49 is released and the force of the spring 44 causes the swing lever 4 to rotate.
1 acts to swivel counterclockwise, so that the side pushing plate 40 pushes the aligned screw heads. When the mounting portion 15 of the magazine thus loaded with screws is inserted into the lateral hole 14 of the sliding member 4, the spring (not shown) of the automatic locking mechanism 60 (FIG. 8) of the mounting portion 15 urges it. The magazine mounting portion 15 is fixed to the sliding member 4 by engaging the claw 61 with the hole 62 of the sliding member 4.
At this time, the tip end of the feed lever 32 in the mounting portion 15 of the magazine is the other lever 8b of the two arm levers 8 in the sliding member 4.
Abutting the end of. To remove the magazine, the magazine may be pulled out from the sliding member 4 while pressing the claw 61.

When the tip end surface of the sliding member 4 of the screw driving device thus prepared is pressed against the screw driving member, one lever 8 of the two arm levers 8 in the sliding member 4 is pushed.
The pin 9 of a is the inclined portion 6 of the guide slot of the casing 3.
Since it is guided along b, the two-arm lever 8 pivots clockwise to the position of the virtual line as seen in FIG.
b pushes the feed lever 32 against the spring 36 into the magazine. As a result, each arm lever 3 in the magazine
2 pivots clockwise about the axis 30 as seen in FIG. 2 and advances the screw feed plate 26 through its respective projections 27 towards the longitudinal axis A of the sliding member by one pitch, thus All the screws held by the screw feeding plate 26 advance by one pitch, and the leading screw of the screw guide groove 20 is fed from the position S _{2 to} the position S ₁ . In the first push stroke,
Thus, the leading screw does not reach the standby position A, but the screw comes to the standby position only after the second push stroke. During this feed stroke, the screw feed plate 26 moves with its vertically movable pin 38 guided from the stroke end a along the feed cam groove 39a of the fixed solid cam 39, and at the lowest stroke level at the stroke end b. Located in. After that, when the sliding member 4 is continuously pushed, the other lever 8a of the two arm levers 8 of the sliding member 4 is pushed.
The pin 9 is the straight part 6 of the guide slot of the casing 3.
While being guided straight into a and the both arm levers 8 are stopped at the turning position as they are during the pushing stroke, the tip of the driver bit comes into the magazine mounting portion 15 and reaches the standby position A. The screw can be driven by a driver bit that engages a screw head and is driven to rotate by a driver tool. In the return stroke, while the return spring 12 causes the pin 9 of the both-arm lever 8 to pass through the straight portion 6a of the guide slot, the both-arm lever 8 does not move,
Therefore, the screw feeding plate 26 is in the same position. Then, when the pin 9 enters the inclined portion 6b, the both-arm lever 8 starts to rotate counterclockwise as viewed in FIG. 2, so that the feed lever 32 starts to move toward the sliding member 4 by the spring 36, and As a result, the screw feeding plate 26 starts to return via the levers 31 on both arms. At that time, when the driven member 38 of the screw feeding plate 26 moves from the lowermost stroke end position b of the three-dimensional cam 39 along the oblique return cam groove 39b and rises, it finally reaches the stroke end position c. The spring 29 returns the same to the stroke end position a. Therefore, the screw feeding plate 26 retreats away from the screw head fed by one pitch, is returned by one pitch, and further moves in the direction orthogonal to the screw guide groove 20 to move the screw feeding plate 26. The recesses 25 of the feed plate 26 respectively engage the screw heads at the next positions. By repeating such a pushing stroke and a returning stroke, the screws in the magazine can be driven continuously. Even if the screws in the first row in the screw guide groove 20 are sequentially fed and the rearmost screw comes to the position of S ₃ in FIG. 7, the head of the screw of S _{3 is in} the second row in parallel with the screw guide groove 20. Since it abuts on the head of the head screw and is pressed from above by the pressure plate 23 of the lid 5b, all the screws in the second row are in the same positions and do not move. However, when the same number of screws (10 in the embodiment) as the second row of screws in the branch thread guide groove 21 out of the first row of screws in the thread guide groove 20 are no longer fed, the branch thread guide groove 21 is fed. The second row of screws are simultaneously pushed out into the screw guide groove 20 by the side surface pushing plate 40. During the screw driving operation, the heads of the screws arranged in the screw guide groove 20 and the branch screw guide groove 21 of the magazine are pressed from above by the pressure plate 23 held by the leaf spring in the magazine lid 5b or the leaf spring 55. Since the screws arranged in the branch screw guide groove 21 are constantly pressed by the side surface pushing plate 40, the screw head side surfaces are always in contact with each other, and therefore the screws do not move even when the magazine is tilted. It keeps its position.

[0023]
