MODE FOR CARRYING OUT THE INVENTION

[0033] Since the present invention may have diverse modified embodiments, preferred embodiments are illustrated in the drawings and are described in the detailed description of the invention. However, this does not limit the present invention within specific embodiments and it should be understood that the present invention covers all the modifications, equivalents, and replacements within the idea and technical scope of the present invention.

[0034] In the following description, the technical terms are used only for explaining a specific exemplary embodiment while not limiting the present invention. The terms of a singular form may include plural forms unless referred to the contrary.

[0035] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0036] FIGS. 3 and 4 are perspective view and a side view of a hand-held X-ray device according to the present invention.

[0037] While the hand-held X-ray device is conveniently carried, the hand-held X-ray device may not accurately perform alignment between an X-ray beam and a subject when photographing without a fixed cradle.

[0038] Thus, the present invention proposes a unit for adjusting and aligning aiming light, which is capable of displaying an X-ray irradiation area in advance at a frontmost portion of an emission hole of an X-ray beam as with the hand-held X-ray device in FIGS. 3 to 5. FIG. 5 is an exploded perspective view of the hand-held X-ray device according to the present invention. The hand-held X-ray device according to the present invention includes an X-ray irradiation part 100, an upper cover 200, a lower cover 300, a lower support 400, and an aiming light guide 500.

[0039] A power button of the device and an aiming light operation button may be disposed on the upper cover 200, and when alignment of the aiming light is accurately completed, the X-ray may be irradiated by pulling a handle lever attached to the lower support 400.

[0040] Preferably, the aiming light operation button may be disposed at a button applicable position on the lower cover 300, the lower support 400, the aiming light guide 500, and the emission hole 600 in addition to the upper cover 200.

[0041] Also, the aiming light may be initially operated by pulling the handle lever attached to the lower support 400, and when the alignment is completed, the X-ray may be irradiated by pulling the handle lever attached to the lower support 400 again.

[0042] Before the X-ray is emitted from the X-ray irradiation part 100, LED light emitted along the aiming light guide 500 is transmitted to the emission hole 600.

[0043] The emission hole 600 passes through an opened surface 710 of a shield plate 700 that blocks the X-ray reflected by the subject and is coupled with the front cover 800.

[0044] A screw thread formed at a front end of the emission hole 600 is screwed into a screw groove formed in an inner surface of the front cover 800, and the emission hole 600 passes through the opened surface 710 of the shield plate 700 and is fitted thereto.

[0045] Preferably, the emission hole 600 includes a contact ring 610, and the contact ring 610 allows the front cover 800 and the emission hole 600 to completely contact each other without an empty space therebetween when the front cover 800 is coupled with the emission hole 600. The contact ring 610 is made of soft solder that is easily processed.

[0046] The front cover 800 adjusts and aligns the X-ray irradiation area by rotating the rectangular collimator to accurately display the X-ray irradiation area while checking the aiming light emitted onto the subject with naked eyes.

[0047] As illustrated in FIG. 6, the front cover 800 includes a front transmission window 810, a cross printing plate 820, a rectangular transmission plate 830, and a cylindrical case 840. A plurality of hooks are disposed in the front transmission window 810, and the hooks are coupled to an inner surface of an edge of the cylindrical case 840 to couple the front transmission window 810 and the cylindrical case 840.

[0048] The cross printing plate 820 is a transparent plate made of an acrylic material printed so that a cross mark may be displayed when the subject is irradiated with the aiming light.

[0049] The rectangular transmission plate 830 induces the aiming light and the X-ray to be emitted onto the subject in a square shape and is made of soft solder that is easily processed.

[0050] The cylindrical case 840 has a screw groove formed at the inner surface of the edge thereof to be screwed with the screw thread formed at the front end of the emission hole 600 and is hooked to the front transmission window 810.

[0051] The front transmission window 810, the cross printing plate 820, and the rectangular transmission plate 830 may be integrally rotated when the front transmission window 810 is rotated in accordance with the subject by attaching surfaces thereof to each other.

[0052] Here, although the front transmission window 810 is rotated simultaneously with the cross printing plate 820 and the rectangular transmission plate 830, the cylindrical case 840 is coupled so as not to be rotated.

[0053] Preferably, as illustrated in FIG. 7, as a rotation projection 811 is disposed on the front transmission window 810, a rotation groove a 821 is defined in the cross printing plate 820, and a rotation groove b 831 is defined in the rectangular transmission plate 830, the rotation projection 811 may be coupled with the rotation groove a 821 and the rotation groove b 831. When the above-described coupling is performed, the front transmission window 810, the cross printing plate 820, and the rectangular transmission plate 830 may be integrally rotated when the front transmission window 810 is rotated in accordance with the subject even without attaching the surfaces thereof to each other.

[0054] Preferably, the present invention may further include a well-known coupling structure capable of integrally rotating the front transmission window 810, the cross printing plate 820, and the rectangular transmission plate 830 as described above.

[0055] When the aiming light of the rectangular collimator is accurately aligned with the X-ray irradiation area, photographing is performed by irradiating the X-ray from the X-ray irradiation part 100.
