Description

[Detailed Description of the Invention] This invention relates to a number sheet attaching device for dental X-ray film.

When taking regular X-ray photographs of the chest, etc., in order to ensure that the photographic film corresponds to the patient or affected area, numbers are made from lead and attached to the X-ray film with adhesive tape at the time of taking the photograph. I was filming. However, dental X-ray film is extremely small (about 30 mm x 40 mm), so
As a result, the numbers had to be made smaller, making it difficult to adopt the above method. Furthermore, the above method itself has the disadvantage that it requires the troublesome operation of adhering the number to the film with tape.

This invention provides a device that can number dental X-ray films by simple means.

FIG. 1 shows a commonly used dental X-ray film, and FIG. 2 is a sectional view of ~ in FIG. 1.
X-ray film F does not transmit visible light, but
The wire is enclosed in a transparent cover C.

FIG. 3 shows the number sheet 10 of this invention.
The number sheet 10 has a number part 12 formed suitably from an X-ray opaque material such as lead or black carbon on the back side of a flexible and transparent sheet 11. Number part 12
is provided by silk screen printing or other various means. In this case, the thickness of the numbered portion 12 is determined in consideration of the material used. Further, the number part 12 is not necessarily formed of numbers, and may of course be formed of ordinary letters and symbols, and in this invention, all of these numbers, letters, and symbols are included in the "number". shall be taken as a thing. An adhesive 13 is further applied to the back surface of the transparent sheet 11 provided with the numbered portions 12. FIG. 4 shows a top view of the number sheet 10 (as seen from arrow A in FIG. 3).

Such a number sheet 10 is attached to the dental X as shown in FIG. 1 or FIG.
It will be attached to an appropriate location on the wire film cover C. At this time, the number part 12 is sandwiched between the transparent sheet 11 and the cover C of the dental X-ray film, so there is no risk of it coming off or peeling off. Since the number part 12 is not exposed even when taking a picture, lead and the like will not enter the mouth, making it extremely safe and sanitary.

As shown in FIG. 5, the number sheet 10 is a long release mount 21 coated with wax or the like on the front or back surfaces.
are pasted on the top at precisely regular intervals. The number tape 20 is thus formed by pasting a large number of number sheets 10 onto the elongated release mount 21. FIG. 6 is a top view of the number tape 20 (5th
(View from the direction of arrow B in the figure). As shown in FIG. 7, this number tape 20 is wound around a hollow core 22 to an appropriate length.

FIG. 8 shows a number sheet attaching device 30 for attaching a number sheet to a cover C of dental X-ray film.
This shows that. This number sheet adhesion device 30
has a fixed base 37, and the following members are attached to the fixed base 37.

That is, 31 is the winding core 22 of the wound number tape.
The winding core 22 is rotatably attached to the shaft 31. G3 is a gear rotatably provided on a fixed base 37, and a pull-out roller 32 for pulling out the number tape is attached to the gear G3 and rotates together with the gear G3. G2 is an intermediate gear that rotates while meshing with gear G3. G1 is intermediate gear G
A pressure roller 33 is attached to this gear G1 and rotates together with the gear G1.

A vertical wall 38 is provided on the periphery of the fixed base 37 and is perpendicular to the fixed base 37 . An opening 39 is formed in a portion of the vertical wall 38 .
From this opening 39, the pressure roller 33
A part of the circumferential part of the ring protrudes slightly.

Reference numeral 36 denotes a separation column, which will be described later, and is fixedly planted on a fixed base 37. G4 is a gear that meshes with gear G3, and a roller is integrally provided. G5 is an intermediate gear that meshes with gear G4, and G6 is a gear that meshes with gear G5. A shaft 35 is integrally attached to the gear G6 and rotates together with the rotation of the gear G6. 34 is a winding core fitted into the shaft 35;
5, can be attached and removed, and
It is adapted to engage with the shaft with appropriate friction so as to rotate integrally with the shaft 35.

In the number tape 20 wound around the core 22 to form one roll, the number sheet 10 is not attached for a predetermined length from the tip of the tape 20. number sheet 1
The part of the number tape 20 on which 0 is not attached (that is, only the peeling mount 21 is attached) is passed through the pull-out roller 32 and hung on the separation column 36, and then bent sharply from the separation column 36 and placed on the roller of gear G4. The leading end of the winding core 34 is fixed to a winding core 34 that is fitted into a shaft 35 that rotates integrally with the gear G6. At this time, the first number sheet 10 of the number sheets of the number tape 20 has reached the separation column 36. This state is shown in FIG.

In the state shown in FIG. 8, the dental X-ray film is placed on the vertical wall 38, and while pressing the leading end of the dental X-ray film against the pressure roller 33 slightly protruding from the opening 39 of the vertical wall 38, When pushed in the direction of arrow M, the pressure roller 33 rotates,
Each gear and roller also rotates accordingly. The direction of rotation is indicated by an arrow.

Therefore, the number tape 20 is pulled out according to the rotation, and the first number sheet 10 is attached to the release mount 21.
At the same time, it tries to be pulled out from the separation pillar.
However, since the release mount 21 is sharply bent at an acute angle at the separation column, the number sheet 10 and the release mount 21 are separated at the point where they pass the separation column 36, and the number sheet 10 is peeled off from the release mount 21. It is being done. The peeled-off number sheet 10 is placed on the pressure roller 33 as it is and reaches the lower surface of the dental X-ray film that is moving in the M direction while being pressed by the pressure roller 33, and is attached to the cover C of the dental X-ray film by the adhesive 13. Glue. On the other hand, the release mount 21
is wound around the winding core 34 by the amount of movement.

In this way, the number sheet 10 is attached to the cover C of the dental X-ray film. During imaging, when the affected area is marked on the X-ray film F by X-ray irradiation, the number 12 on the number sheet does not transmit X-rays, so it is clearly distinguished from other parts. It is projected onto line film F. Therefore, the patient or the patient's affected area and X that shows this
Linear film F will definitely correspond to this.

In the above description, the dental X-ray film was pressed against the pressure roller 33 and moved in the direction of the arrow M, but conversely, the dental X-ray film may be fixed and the device 30 itself moved. is also possible.

In other words, if the gears and rollers on the fixed base 37 are made as small as possible and the space is used effectively,
The size of the fixed base 37 can be about the size of a person's palm. Therefore, by covering the vertical wall around the fixing base with a lid, the device 30 itself becomes one small case. A portion of the pressing roller 33 protrudes from the opening 39 of the case. Therefore, by holding this case in your hand, pressing the pressing roller 33 against appropriate locations on the dental X-ray film placed on a flat surface such as a desk, and moving the case in the direction opposite to the M direction, the same result as described above will occur. A number sheet can be attached to the dental x-ray film.

As described above, in this invention, the wound number tape is moved by relative pressure movement between the dental X-ray film and the pressure roller, and an acute-angled separation column is provided, and the number sheet is numbered by the movement of the tape. Since the number sheet is automatically separated from the tape and simultaneously attached to the dental X-ray film by pressure, the trouble of manually tearing off the number sheet one by one and adhering it to the X-ray film is eliminated, and the relative pressure movement The number sheet can be reliably and easily attached to the X-ray film in a single operation. This is particularly effective when number sheets are attached to many dental X-ray films at the same time.
