The rotary arm supporter 400 may include rotary arm rotary means 410 capable of rotationally driving the rotary arm 500, as shown in the figure. The panoramic and citi X-ray photographing apparatus 1 is advantageous as more cross-sectional images are provided in order to improve the quality of the photographed image of the receiver 3.

Therefore, the panoramic and Citi X-ray imaging apparatus 1 according to the present invention preferably photographs while rotating the rotary arm 500 several times more than 360 degrees, to prevent twisting of the internal cable, etc. during rotation For this purpose, it is more preferable to rotate the rotary arm 500 in a rotation range of 430 degrees.

Rotating arm rotating means 410 capable of rotationally driving the rotary arm 500 of the present invention may include a rotation drive motor 430 and the timing pulley 440 mounted to the base plate 420. In the present invention, the timing pulley 440 may include a first timing pulley 440 ′ and a second timing pulley 440 ″, and the number of timing pulleys mounted on the base plate 420 is not limited. .

In addition, the rotation drive motor 430 and the first timing pulley 440 ′ are connected to the timing belt 441, and the first timing pulley 440 ′ and the second timing pulley 440 ′ are the timing belt 442. May be connected to each other. Therefore, the rotational power generated by the rotation drive motor 430 is transmitted to the second timing pulley 440 ″ through the first timing pulley 440 ′.

A disk-shaped first rotating plate 460 is mounted on an upper surface of the second timing pulley 440 ″, and a disk-shaped second rotating plate 470 is mounted on an upper surface of the first rotating plate 460. The first rotary plate 460 is formed with a first rotary plate stopper 461, and the first locking jaw 471 and the first locking plate 471 are formed at a lower side of the second rotary plate 470 in contact with the stopper 461 of the first rotary plate. 2 engaging jaw 472 is formed. Accordingly, the first rotating plate 460 may be rotated between the first locking jaw 471 and the second locking jaw 472 of the second rotating plate 470, where the rotation range may be rotated to 95 degrees. It is preferable to form the locking step 471 and the second locking step 472.

In addition, a second rotating plate stopper 473 is formed on an upper surface of the second rotating plate 470, and the base plate 420 may contact the second rotating plate stopper 473 to stop the rotation of the second rotating plate 470. The rotary arm mechanism stopper 480 is formed. In addition, the second rotating plate 470 may form the second rotating plate stopper 473 and the rotary arm mechanism stopper 480 to have a rotation range of 335 degrees.

In addition, after the second rotating plate rotates from one side (for example, the forward rotation start position) of the rotary arm mechanism stopper 480 to the other side (for example, the forward rotation end position), the rotation arm to prevent movement. A magnet 481 for attaching the second rotating plate stopper 473 to the other side of the mechanism stopper 480 by magnetic force may be attached, and the second rotating plate stopper 473 may also be formed of a magnetic or metal component.

6 (a) to 6 (c) are exemplary views showing a forward rotation operation by the rotation means of the rotation arm support unit according to the present invention.

As shown in FIG. 6A, when the second timing pulley 440 ″ is rotated by the forward rotation operation of the rotation drive motor 430, the first rotation plate 460 is rotated at the forward rotation start position. At this time, the second rotating plate 470 is rotated in conjunction with the first rotating plate 460 by the friction force by its own weight.

Thereafter, as shown in FIGS. 6B and 6C, the second rotary plate stopper 473 of the second rotary plate 470 faces the rotary arm mechanism stopper 480 and rotates until the movement is stopped. As the second timing pulley 440 ″ is rotated, the first rotating plate 460 rotates from the first locking step 471 of the second rotating plate 470 to the position of the second locking step 472. At this time, the rotation range of the second rotating plate 470 may be rotated within 360 degrees, preferably 335 degrees, and the rotation range of the first rotating plate 460 may be rotated within 180 degrees, preferably 95 degrees.

Accordingly, by the rotation operation of the second rotating plate 470 and the first rotating plate 460, the connecting shaft 401 interlocked with the first rotating plate 460 rotates to rotate the rotating arm 500 in the range of 430 degrees. Can be rotated.

The strength of the frictional force, magnetic force, and rotational force applied to the second rotating plate 470, the first rotating plate 460, and the rotary arm mechanism stopper 480 is “Frictional force due to the second rotating plate weight <the second rotating plate stopper and the rotating arm. Magnetic force of the mechanism stopper &lt; rotation force by the first rotating plate and the first and second locking jaws &quot;

Therefore, when the forward rotation operation of the rotation drive motor 430 is finished and the reverse rotation, the second rotation plate 470 by the magnetic force between the second rotary plate stopper 473 and the magnet 481 of the rotary arm mechanism stopper 480. This can be fixed to prevent errors in position values.

As shown in (a) to (c) of FIG. 7, in the case of reverse rotation after the forward rotation operation of the rotation drive motor 430 is finished, the first rotating plate 460 rotates in the reverse rotation direction, and The first rotating plate stopper 461 of the first rotating plate 460 faces the first locking step 471. At this time, the second rotary plate stopper 473 is separated from the magnet 481 of the rotary arm mechanism stopper 480 by the rotational power of the first rotary plate 460, and the second rotary plate 470 is the first rotary plate 460. It rotates in the reverse direction in conjunction with.

Thereafter, when the second rotary plate stopper 473 of the second rotary plate 470 reaches the forward rotation start position, the second rotary plate 470 faces one side of the rotary arm mechanism stopper 480, and the reverse rotation operation of the second rotary plate 470 stops. Since the first locking step 471 of the stationary second rotating plate 470 and the first rotating plate stopper 461 are in contact with each other, the reverse rotation operation of the first rotating plate 460 is also stopped.

As described above, the second rotary plate stopper 473 is the rotary arm mechanism stopper by interlocking the stopper 461 of the first rotary plate 460 and the first locking jaw 471 of the second rotary plate 470 during reverse rotation. The second rotating plate 470 is stopped and stopped by returning to the forward rotation start position which is one side of the rotary arm mechanism stopper 480 away from the magnet 481 of 480. The first rotating plate 460 is returned to the starting position by the first locking step 471 of the rotating plate 470 and stopped. For this reason, the rotary arm 500 connected to the first rotating plate 460 through the connecting shaft 401 has a feature of preventing a position error when performing the forward and reverse rotation operations.

FIG. 8 is a configuration diagram showing an internal configuration of a rotary arm of the dental panoramic and Citi X-ray imaging apparatus viewed in the direction A of FIG. 1.

[ The connection shaft fixing member 543 may also be mounted on and fixed to a connection shaft 401 connecting the rotary arm supporter 400 and the rotary arm 500.

At least one LM guide rail 544 such as a pair of LM guide rails 544 and 544 is mounted on the upper side of the rotary arm 500 and the LM guide rails 544 and 544 The LM guide supporting members 545 and 545 can be mounted on the connecting shaft fixing member 543 so as to be interlocked with each other.

A hollow portion 546 is formed in the longitudinal direction of the rotary arm 500 so that the connection shaft 401 penetrates the hollow portion 546 and is connected to the connection shaft fixing member 543. [ In addition, the hollow portion 546 may be formed to have a horizontal movement space in a state where the rotary arm 500 is fixed to the connection shaft 401.

The rotational power generated by the rotary arm horizontal drive motor 541 is transmitted to the rotary arm horizontal drive ball screw 542 and converted into horizontal linear motion and is transmitted to the other end of the rotary arm horizontal drive ball screw 542 by horizontal linear motion The LM guide supporting member 545 of the connected connection shaft fixing member 543 can be slidably moved along the LM guide rail 544.
