[Industrial applications]

 The present invention relates to a film pressure bonding mechanism used in a cassetteless X-ray imaging apparatus.

[0002]

[Prior art]

 A conventional film pressure bonding mechanism will be described with reference to the drawings. FIG. 4 is a configuration diagram illustrating a first example of a conventional film pressure bonding mechanism. In the figure, 1 is an upper plate, 2 is a lower plate on which a film 5 is placed via a pressure-bonding sponge 4, and which is provided at the base end of the upper plate 1 via a hinge mechanism 3 so as to be openable and closable.

FIG. 5 is a configuration diagram illustrating a second example of a conventional film pressure bonding mechanism. In the figure, 5 is a lower plate on which a film 7 is placed via a pressure-bonding sponge 6. Reference numeral 8 is an upper plate provided so as to be movable in parallel to the lower plate 5 via a parallel link mechanism 9.

[0004]

[Problems to be solved by the device]

 However, the film pressure bonding mechanism having the above configuration has the following problems. In the film crimping mechanism having the structure shown in FIG. 4, the lower plate 2 has to be largely opened to open the crimping sponge 4 near the hinge mechanism 3, and a large opening space is required when the film 5 is set in the cassette. And

In particular, in order to improve the close contact between the intensifying screen and the film 5, the crimping plate provided on the inner surface of the upper plate 1 is warped, and the opening is particularly large. The film crimping mechanism having the configuration shown in FIG. 5 does not require a large opening space when the film 7 is set in the cassette, but has the parallel link mechanism 9, which makes the mechanism complicated.

The present invention has been made in view of the above problems, and an object thereof is to provide a film crimping mechanism that does not require a large opening space and has a simple mechanism when setting a film. is there.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of the construction of a first embodiment of the present invention, and FIG. 2 is a side sectional view of FIG.

In the figure, 11 is an upper plate. The upper plate 11 includes an upper surface portion 12, first side surface portions 13 and second side surface portions 14 which are bent downward from both sides of the upper surface portion 12 at a substantially right angle, and is disposed below a base end portion of the upper surface portion 12. The base end surface portion 15 bent at a substantially right angle, and the first and second side surface portions 13 and 14 and the base end surface portion 15 are bent at a substantially right angle, respectively, and face the upper surface portion 12, near the base end portion. Other than the above, the first lower surface portion 16 is open.

Reference numeral 17 is a holding plate. The holding plate 17 is arranged so as to face the surface of the first side surface portion 13 of the upper plate 11 on the second side surface portion 14 side, and the base end portion thereof is the first side surface of the first side surface portion 13. The third side surface portion 18 rotatably provided at the base end portion of the side surface portion 13 and the surface on the first side surface portion 13 side of the upper plate 11 of the second side surface portion 14 of the upper plate 11 face each other. The fourth side surface portion 19 rotatably provided at the base end portion of the second side surface portion 14 of the upper plate 11 and the first lower surface portion 16 of the upper plate 11. The second lower surface portion 20 is disposed on the open surface and both sides thereof are connected to the third side surface portion 18 and the fourth side surface portion 19, respectively.

21 is disposed between the upper plate 11 and the pressing plate 17, a film 23 is placed on the upper surface via a pressure-bonding sponge 22, and a base end portion of the first plate of the upper plate 11 is in an open state. It is a lower plate that abuts a protrusion 16 a formed on the lower surface 16.

A base end portion of the crimp pin 24 is attached to a substantially middle portion of the lower plate 21. The middle portion of the crimp pin 24 is loosely fitted into the hole 20a formed in the second lower surface portion 20 of the pressing plate 17, and the head portion is engaged with the lower surface of the second lower surface 20 of the pressing plate 17. However, further downward rotation of the presser plate 17 is prohibited.

Further, a spacer 25 is fixed to an intermediate portion of the crimp pin 24, and the base end portion of a leaf spring 26 as an urging means is attached to the lower plate 21 by the spacer 25. The tip end portion of the leaf spring 26 is pressed against the second lower surface portion 20 on the tip end side of the pressing plate 17 with respect to the crimping pin 24, and holds the lower plate 21 substantially parallel to the upper plate 11 in the open state.

Further, on the second lower surface portion 20 of the pressing plate 17, a projection portion 20 b projecting toward the lower plate 21 is formed on the tip end side of the leaf spring 26. Further, 30 is a lock mechanism which is provided at the tip of the pressing plate 17 and can lock the upper plate 11.

FIG. 3 is a top view of the lower plate 21 viewed from the upper plate 11 side. In this figure, the part indicated by the chain double-dashed line is higher than the other parts. Next, the operation of the above configuration will be described. In the open state, the base end portion of the lower plate 21 abuts on the projection 16a of the first lower surface portion 16 of the upper plate 11, and the intermediate portion of the lower plate 21 is held by the biasing force of the leaf spring 26. The plate 21 is substantially parallel to the upper plate 11 via a space. In this state, the film 23 is set.

Next, when the pressing plate 17 is rotated in the direction of the upper plate 11 (closing direction), the base end of the lower plate 21 is moved to the first lower surface part 16 of the upper plate 11 by the urging force of the plate spring 26. The tip end side rotates in the direction of the upper plate 11 while being in contact with the protrusion 16a, and comes into contact with the upper plate 11 from the tip end side of the lower plate 21.

Further, when the pressing plate 17 is rotated in the direction of the upper plate 11, this time, the base end part (A part in FIG. 2) of the second lower surface part 20 of the pressing plate 17 presses the lower plate 21. The contact between the base end side of the lower plate 21 and the protrusion 16a of the first lower surface part 16 of the upper plate 11 is released, and the base end side of the lower plate 21 also moves toward the upper plate 11, The protrusion 20b of the holding plate 17 and the spacer 25 press the lower plate 21, and the lower plate 21 and the upper plate 11 are entirely brought into contact with each other via the film 23 and the pressure-bonding sponge 22. Then, the lock mechanism 30 is used to prohibit downward movement of the holding plate 17.

According to the above configuration, when setting the film 23, it is possible to secure a sufficient space for setting the film 23 between the lower plate 21 and the upper plate 11 with the holding plate 17 slightly opened. Moreover, the mechanism required for film pressure bonding is simple. In addition, since the two-dot chain line portion of the lower plate 21 is raised more than other portions, air is exhausted smoothly during crimping and air generated between the film 23 and the intensifying screen (not shown). Prevent the occurrence of accumulation.

Further, at the time of crimping, the force acting on the pressing plate 17 is converted into a reciprocating motion with the point A as a fulcrum, so that the operating force can be reduced. The present invention is not limited to the above embodiment. Although the leaf spring 26 is used as the urging means in the above embodiment, a coil spring or the like may be used.
