Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a film interpretation device having a reliable automatic feeding mechanism for multiple sheets of film, and in particular, for reliably separating films laminated and in close contact into each sheet. The present invention relates to an automatic film interpretation device that is configured to feed out the film and feed the film to the image interpretation device in an optimal posture.

Therefore, in the past, this type of film interpretation, especially the interpretation of chest indirect radiography films, etc., consisted of placing the film on the surface of a light box such as a Scherkasten for each lobe, and recording the findings in the medical record. This resulted in a lot of time being spent on interpretation and diagnosis. In addition, the inconveniences of the prior art were particularly noticeable when arranging the films of a large number of patients or extracting a specific film from a large number of films. In addition, when comparing and diagnosing films for a given patient, there is a risk that the recognition of the previous and succeeding films may become unclear, leading to errors in the interpretation of a series of films.

In view of the inconveniences in the prior art, the film interpretation device according to the present invention automatically guides multiple sheets of film onto the illumination box surface one after another, and enables continuous interpretation of multiple sheets of film. This makes it easier to enter medical records during film diagnosis, and also ensures mutual comparative diagnosis based on continuous interpretation of films. Furthermore,
It is particularly expected that it will facilitate the arrangement of multi-layered films or the removal of specific films from multi-layered films, thereby streamlining and speeding up diagnosis.

In addition, in the device according to the present invention, in view of the characteristics of the film that tends to adhere closely, the film is reliably fed out separately, and the posture at the time of feeding is corrected to prevent twisting, distortion, and warpage on the image reading surface. This is to ensure that problems such as these are avoided.

At the same time, the base of the plate (5) a is brought into contact with the circumferential surface of the cam (7). Call cam (7)
By feeding the spring (18) against the bone spring force caused by the cam (7) and by feeding the bone by the spring (18) due to the missing cam (7), the film a, which was bent first with the claw (13), is cut into a plate. (5) erected at the free end of a;
Moreover, the claw (18) protrudes from the hole (14) of the pedestal (1).
The film a is fed into the Scherkasten device while being hooked on the film.

The cams (8) and (7) are mounted on the drive shaft (2o), and the operation of the cams (6) and (7) and the feeding device B for film a described below are as follows. The gear (21) mounted on the shaft (20) works in tandem with each other.

In order to observe the intermittently supplied film a and feed it to the device, a double belt (22) made of urethane material with relatively high frictional resistance is arranged 7, and this double urethane belt (22) is used. 22) and (22), the 1° film a is pushed between them using the feeding member (5). In addition, in order to keep the film a parallel to the surface of the observation device and to avoid bending or distortion during feeding, a constant velocity belt (23) is used to hold the film a (22). It is arranged so as to face the .

That is, the gear (27) of the shaft (26) having the pulley (25) of the belt (22) is driven through the gear (24) that meshes with the previous gear (21), and this pulley (25) is driven.
The belt (22) mounted on the shaft (2B) is driven at one longitudinal edge of the observation device C, and the belt (22) is mounted on the pulley (25) a provided on the shaft (2B).
3), the belt (23) is twisted through a guide roll (28) in a direction perpendicular to the feeding direction of the film a, and the belt (23) is mounted on a pulley (28).

This allows the belt (2) to run while holding the film a.
2) and the bell mounted on the pulley (29)) (23
) and the linear speed of the belt are perfectly matched, making it possible to feed the film a accurately and uniformly.

Next, the observation device C for film a is commonly called a lamp house, and is made of a mold that effectively uses aluminum extrusion material, etc., and has various shapes depending on the type, shape, size, etc. of the film a to be observed. The aspect is what was planned. In the illustrated example, the outer casing (30) and the inner casing (3
1), a chalk or other equipment is placed between the outer casing (30) and the inner part (31), a fluorescent tube, etc. is placed in the inner part (31), and an inorganic material is placed on the opening surface of the inner part (31). A transparent plate (32) such as glass or a diffused acrylic plate is arranged. Furthermore, inside e
! (31) has a sponge (3) in its opening groove (31)a.
3) to provide good contact with the film a and to perform a buffering function when the transparent plate (32) is fitted, and also to attach a contact plate (34) to the groove (31) b, A transparent plate (32
) was dropped horizontally. Next, the previous belts (22), (22) are inserted into the groove (31) c divided by the contact plate (34), and the belt (22) is inserted into the guide roll (35). )
- (35) are appropriately supported to prevent the deflection. In addition, this roll (35) is always elastically supported by a guide spring (36), and a curved receiving part (3B) a that supports the roll (35) a.
on one free end, and the other free end on the groove (31) c
The bent part (3B) b is in contact with the side wall of the coil part (3B). It is constructed by bending it into a shape.

The film supply and observation device according to the present invention has the characteristic structure described above, in particular, it separates and feeds the film a by bending it downward one by one, and furthermore, it separates and feeds the film a by bending it downward one by one. While feeding the film into the observation device at a uniform speed, evenly roll the sides of the film a) (
22) and (22), a so-called "plane" type clamping feeding was achieved, thereby achieving a concrete effect of the above-mentioned characteristics.

Therefore, it is possible to set a series of films to be observed at once and then automatically transfer and feed the films one after another to the observation surface, without having to set the films one by one and send them to the observation surface. Therefore, it is possible to quickly and skillfully observe a large number of films, and it has also brought good results to comparative studies of observed films. Incidentally, by installing a variable motor in the drive device, it is possible to rearrange the films by fast forwarding, take out a specific film for observation, and stop and observe a specific film.

This automatic feeding system also has the advantage of allowing the interpretation of X-ray indirect photography films to be performed together with medical chart operations.

Next, the adhesion resistance between the laminated films a and the electrostatic adhesion were released and ejected using device A, and the films were fed to observation device C while being reliably separated. In device B, the feeding speed on both sides of film a is made uniform to reliably prevent tilting, distortion, etc. of the transported film, and at the same time, film a is held by belts (22) and (22) to It is designed to transport and supply the specimen in parallel to the observation device C.

Next step: attach the transparent plate (32) to the backing plate (33) and the groove (31)
By dropping the mask between the holes a and a, it is easy to replace the mask according to the size of the observation film, and the belt (22) is supported by the roll (34) that is sprung by the spring (35). Belt (22)
This ensures that the bending of the material is prevented.

In particular, the spring (35) is simply a groove (3) due to its structure.
1) It is possible to support the roll (34) only by fitting it into the groove (31) c, and it can be set immediately by sequentially pushing it in from the opening side of the groove (31) c.

The film observation device according to the present invention brings about particularly good results in the interpretation of various films such as X-ray indirect photography film, aerial photography film, oscillographic film, micro photography film, computer camera film, etc., especially in continuous interpretation, and provides appropriate results. It was used for medical and other treatments.
