The lock plate is rotatably attached to the lower end of the body above the axle and rearward of the axle by the first support shaft, and the first hook portion is provided on the central side of the lower portion of the body. A first coil spring is attached between the first hooking tool and the first hooking portion, The lock plate is always pulled in the clockwise direction, and the upper end of the elongated vertical part of the slide fitting is held between the lower flat part of the lock plate and the side part of the body.

5 Action When drawing the dotted line, put lime in the body and push the handle to rotate the tire, which is guided inside the upright wall against the elastic force of the leaf spring inside the tire and attached from the second spindle. The operating metal fitting also started to rotate, abutted against the second raised portion provided below the axle on one side of the sliding metal fitting, and the powder stop plate attached to the sliding metal fitting also rotated clockwise, Start opening the lime outlet provided on the bottom surface of the lower part of the vessel (see FIGS. 4 and 5). When the tire further rotates, the actuating metal fitting attached to the tire comes into contact with the arcuate stepped portion of the release plate attached to the side of the circular portion at the lower part of the body, and gradually the tire centering on the second spindle. It seems to collapse in the outer peripheral direction, and the second
When the raised part of the body passes between the step and the lower part of the body (6th
(See FIGS. 7 and 8), the actuating metal fitting comes into contact with only the step portion of the release plate and does not press the second raising material, and at the same time, the upper end of the first raising material provided above the axle of the slide metal fitting. Moves while pushing up the lower flat part of the lock plate, and when it exceeds the locking part of the lock plate, the second coil spring provided between the second hooking tool and the second hooking part of the slide fitting reverses the reaction. The slide metal fitting is pulled in the clockwise direction, and at the same time, the first coil spring provided between the first hooking portion of the lock plate and the first hooking tool causes the first fitting of the slide metal fitting to the locking portion of the lock plate.
The raised portion is locked and held. When the tire rotates further, the actuating bracket no longer contacts the step of the release plate, and the distance from the support shaft to the leaf spring to the corners on both sides in the tire outer peripheral direction is greater than the distance to the leaf spring. Becomes longer,
The leaf spring returns to the original state. When the tire further rotates, the actuating fitting comes into contact with the inside of the wall surface of the lock plate and starts to lift the lock plate. At this time, the actuating metal fitting contacts the leaf spring even when pushed from the tire outer peripheral direction, and the corners on both sides near the axle contact the leaf spring at a distance from the support shaft. The corners that are longer than the corners on both sides and that are closer to the axle have no gap in the axle direction between the leaf spring and the upright wall of the tire, so the actuating metal fitting is retained without falling in the axle direction. . When the tire was rotated 180 ° after opening the lime discharge port, the powder stop plate with the operating metal fitting attached to the slide metal fitting further lifted the lock plate and locked it on the locking part of the lock plate. The first raised portion of the slide fitting is released (see FIGS. 8 and 9). At the same time, the powder stop plate attached to the slide fitting is also attracted by the second coil spring, the lime discharge port at the bottom of the vessel is closed, and lime discharge is stopped. At the same time, the second hooking tool comes into contact with a stop portion formed by bending downward toward the rear of the second hooking tool and stops. At the same time, the first coil spring keeps the lock plate always pulled in the clockwise direction. From here, the lime outlet is closed while the actuating metal fitting is rotated by 180 °, the discharge of lime is stopped, and by repeating this, the dotted line is continuously drawn. When you want to draw a straight line, pull the lever up and the slide metal fittings connected by wire will move up and down with the axle as the fulcrum, and the powder stop plate attached to the slide metal fittings will be the lime outlet at the bottom of the body. When the handle is released with the lever opened in this state, a straight line will be drawn continuously.
