Ru. As described above, in this case 3, when the force point part 12 of the case 1 and the driving arm 10a are in the same motion state, the driven arm end 33 of the case 1
If the direction of transmission and movement is defined as the positive direction, the driven arm end 3
3 is motion transmission moving in the opposite direction. Above case 1,
Combining the movements of 2.3, in this embodiment, the driving arm 10a
The reciprocating movement of the force point part 12 is in the positive direction at the driven arm end 33,
As explained above, according to the present invention, the driving lever and the motion control lever each swing in a parallel plane around a fixed axis. The extension line connects the midpoint of the arc drawn by the working arm of the driving lever and the center of the fixed shaft of the driving lever, and the midpoint of the arc drawn by the first arm of the driven lever and the center of the fixed shaft of the driven lever. In a positional relationship such that the extension line connecting the two ends is perpendicular, one end of the first connecting rod having the same length as the working arm of the driving lever is placed at the end of the working arm, and the angle between the working arm and the first connecting rod is A second connecting rod of the same length as the first connecting rod is connected at an acute angle.
One end of the connecting rod is connected to the other end of the first connecting rod, the other end of the second connecting rod is connected to the first arm end of the driven lever, and then the first and second connecting rods are connected to each other. One end of the third connecting rod is connected to the connecting part, and the other end of the third connecting rod can be controlled in motion, so that the slave lever side can be controlled in the forward and reverse directions with respect to the reciprocating movement of the driving lever. To make it possible to freely convert between reciprocating motion and a stationary state by operating a motion control lever, and to make a link machine with good transmission efficiency, high precision, and capable of transmitting even larger power. By incorporating it into the mechanism of rosette walking using an automatic machine, it is possible to save transmission energy, transmit accurate motion, and transmit large force, which has remarkable practical effects.

揺動円弧上の所定の位運動伝達機構。It has a driving lever, a motion control lever, and a driven lever, each of which swings in a parallel plane around a fixed axis, and an extension line connecting the midpoint of the arc drawn by the operating arm of the driving lever and the center of the fixed axis of the driving lever. The first connecting lever has the same length as the working arm of the driving lever in a positional relationship such that the extended line connecting the midpoint of the arc drawn by the first arm of the driven lever and the center of the fixed shaft of the driven lever is a permanent line. One end is connected to the end of the working arm so that the angle between the working arm and the first connecting rod is an acute angle, and one end of a second connecting rod having the same length as the first connecting rod is connected to the first connecting rod. The other end of the second connecting rod is connected to the first arm end of the driven lever, and then one end of the third connecting rod is connected to the connecting portion of the first and second connecting rods. and the other end of the third connecting lever is connected to one end of the motion control lever, and a motion transmission mechanism is provided for a predetermined position on a swing arc drawn by the connecting portion of the motion control lever and the third connecting lever.
