When one operation button 10a of the operation switch 10 is continuously depressed in this state, the current from the electrolytic corrosion passes through the motor 9 and one limit switch 1, and the other limit switch 1, as shown in FIG. It passes through the switch ■.2 and the diode 65 and returns to the power supply (in the direction of the arrow in Fig. 9).At this time, the motor 9
As shown in FIG. The slat 5 begins to tilt due to the cooperation between the winding drum 6 and the rutter cord 4. Further, as the connection lll1l120 rotates, one end 22a of the protruding piece 22 engages with the one end surface 24a of the engaging portion 24 of the actuating member 260, and the actuating member 26
It is rotated integrally with 0. As shown in FIG. 8(a), as the actuating member 26 rotates, the dock 25 engages the actuator 1-28b of one of the second elastic pieces 28, and then the actuating member 26 further rotates. -T'-(C When rotated, the second elastic piece 28 is bent downward, and its contact pin 6

In the meantime, the motor 9 is stopped by releasing the other metal 1 and 2, and the motor 9 is stopped, and the rotation 11i1112 is stopped at a constant angular position. As a result, the 11th slab! 5 is located at a second tilting limit <11 (not shown) in the opposite direction to the first pivoting gap limit position shown by the chain line in FIG. In addition, when the slabs 1 to 5'fr with tilting self are placed in a flat state, the pair of operation buttons 1t]a, 1

Furthermore, in the actual example M, it is obvious that the second elastic piece 28.48 has the full elasticity to prevent it from being bent by the weight of the toss 25.

In addition, in this embodiment, the actuators 28 b and 48 b of -Me 1 are coupled 11111 + 2 [1 of 1
Since the limit switch L1. L2 can be easily assembled.

Each member such as 1, 1, 25, etc. is expressed by the relational formula, 360- (
Since it is configured to satisfy the condition a10β)10−γ≦1, the position of the device 1 of the limit switches T, 1, and L2 is not limited, and moreover, the pair of limit switches L1 ．． The selection operation of i, 2 can be ensured.

-Manotsu This invention is not limited to the above-mentioned embodiment (C), and can be embodied in devices other than the fly grinder.

As described in detail above, the present invention has an operating member, so that even if the rotation angle of 11illI is set large, the placement position of the limit switch is not limited, and the position can be easily adjusted. In addition to being able to set the limit switch to a fixed position, one rotation can be stopped at a predetermined angle position, and the structure is simple and compact. be effective.
