Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a sheet storage device that can smoothly store recorded sheet-like information recording carriers such as X-ray sheet film after imaging, regardless of the orientation (orientation) of the device. Relates to equipment suitable for storage in.

Here, we will first explain the usage pattern using a conventional X-ray imaging apparatus, and also discuss the problems of the conventional technology with respect to the newly required usage pattern. 1 to 5 show conventional devices. In Fig. 1, 1 is the main body of the sheet film photographing device, 2 is a supply magazine that stores unphotographed sheet film 3, 4 is a film outlet of the supply magazine, 5 is a receive magazine that stores photographed sheet film 6, and 7 is a receiver. Magazine film storage opening, 8
~12 is a roller that feeds the sheet film, 1
3 and 14 are guide plates for guiding the sheet film;
15a and 15b are intensifying screens constituting the photographing portion. In FIG. 1, the unphotographed sheet film 3 stored in the supply magazine 2 is rotated one by one in the direction of the arrow by a mechanism (not shown) through the film outlet 4 on rollers 8 and 9.
It is sandwiched in between and sent between intensifying screens 15a and 15b. By a mechanism not shown, the intensifying screens 15a and 15b are brought into close contact with the fed sheet film 3', and photographing is performed here. After photographing, the intensifying screens 15a and 15b are released from close contact, and the photographed sheet film is transferred to the rollers 10,
11 and 12, the film passes through the film storage opening 7 and is stored in the receive magazine 5.

The photographing method using the sheet film photographing device shown in FIG. 1 is as shown in FIGS. 2 and 3, in which the photographing surface 16 is fixed horizontally or vertically to the floor, or Figures 4 and 5
The arm 18 rotates around point A as shown in the figure.
There are cases in which a sheet film photographing device is attached to the sheet film, and photographing is carried out while rotating the sheet film within a range of 90 degrees, which is the position indicated by the two-dot chain line in FIG. Here, 17 is an X-ray tube, M is a subject, and FIG. 5 is a side view of FIG. 4. In such a conventional photographing method, the storage opening 7 of the receive magazine 5 does not face the floor side. Therefore, there is no possibility of a situation in which a new photographed sheet 6 must be stored against the gravity of the photographed sheet film 6 already stored in the receive magazine 5.

In the conventional photographing method as described above, the following is required for the photographed film storing mechanism of the sheet film photographing apparatus. That is, the curling phenomenon of the photographed sheet film 6 already stored in the receive magazine 5 occurs when the receive magazine 5 is placed perpendicular to the floor surface. To prevent the photographed sheet film 6 newly entering the receive magazine 5 from being obstructed by the falling of the photographed sheet film 6 already stored.

A conventional film storage mechanism that meets these requirements is the Utility Model Publication, 1972-
There are 10551, 1974-22380, etc.

Recently, with the advancement of imaging technology and in order to pursue images with higher diagnostic ability, a sheet film imaging device is attached to the arm 19 as shown in Figs. 6 and 7, and the sheet film imaging device is slid in the direction of the arrow in Fig. 6. At the same time, research is underway on a device that can be rotated around point B in FIG. 7 to take pictures from any angle. Here 17 is X
A radiation tube M indicates a subject, and FIG. 7 is a side view of FIG. 6. In the case of this photographing method, considering the state in which the receive magazine 5 is placed, the film storage opening 7 moves from the horizontal position D facing the ceiling to the vertical position E, and furthermore, as shown in FIG. It is also conceivable that the robot 7 is in an up-and-down position G where it faces the floor. In particular, at the vertically overturned position G, the photographed film 6 that has already been stored falls downward due to its own weight, thereby obstructing the path of the photographed sheet film 6 that will be stored next. The photographed film storage mechanism according to the prior art cannot deal with this problem, and a phenomenon occurs in which the photographed sheet film 6 cannot fit into the receive magazine 5.

An object of the present invention is to enable effective storage operation no matter what attitude the storage device takes when the operator selects an arbitrary angle. In addition, especially when the storage device is turned upside down compared to the conventional usage mode, by supporting the four outer peripheries of the recorded sheet-like record carrier that is already stored in the device storage chamber, it is possible to store the recording medium next time. The recording medium is configured to form a storage space that temporarily stores the record carrier. However, the present invention should not be limited to devices that are turned upside down during use.

An example will be described below using FIGS. 9 to 18, and its outline will be explained in advance. FIG. 9 shows a side view including a partially cutaway view of the embodiment receive magazine, and FIGS. 10 to 13 show longitudinal sections after the magazine lid 23 is opened. Also, H-H, I- in each figure from Figure 10 to Figure 13.
I, JJ, and K-K cross sections are drawn in FIGS. 14 to 15, and the upper half and lower half of FIG. 18 respectively show an upward view and an upward view when the cover is removed.
Note that this receive magazine corresponds to magazine 5 in FIG.

Reference numeral 36 in FIG. 9 denotes a side support member, which forms a U-shape as shown in FIG.
Forms a storage space that temporarily accommodates. Also, side supporting members 36 and 3 as side supporting members
The lower end of 6' has the function of supporting the sides of the sheet film F' already stored and isolating it from the storage space when the receive magazine is turned upside down. Therefore, it is desirable to provide a length that exceeds half of the length of the sheet film, taking into account the normal deflection of the sheet film. Furthermore, although the lower ends of the side supporting members 36 and 36' in the embodiment are formed of continuous plates, they may also be shaped like the teeth of a comb.

Next, the number 42 on the right side of Fig. 10 is a front claw as a rear end side support member, and when the receive magazine is turned upside down, the rear end of the sheet film F' that is already stored (the sheet film is fed It has the function of supporting the rear edge of the housing and isolating it from the storage space. Then, when moving the sheet film F to the storage chamber, as shown in Fig. 15,
6 and 36' swing, and as shown in Fig. 11, the front claw 4
2 retreats from the transition path, and further, in consideration of the case where the sheet film does not migrate due to gravity, the pushing plate 47 as a transition member is lowered along the transition path from the storage space to the storage chamber (Figs. 10 to 10). Figure 12).

On the other hand, the sheet film fed at high speed from the main body of the X-ray photographing apparatus collides with the inner wall of the receive magazine and bounces off, making it difficult to accommodate the sheet film, which is a problem already mentioned. In this embodiment, in addition to the collision energy absorbing material 60 (left side in Figure 10) provided on the inner wall, a roller 59 with a strong frictional surface is provided to prevent the sheet film from rebounding. 59 has a function of supporting the front end of the sheet film (meaning the front end when the sheet film is fed) when the receive magazine falls vertically. That is, member 5
Reference numerals 9 and 60 constitute distal end side support members.

The configuration will be explained in more detail below.

When this receive magazine is fixed to the camera body and the magazine lid 23 is opened, a mechanism (not shown) moves the feed roller 26 and guide plate 27 into the receive magazine from the camera body side as shown in FIG. The feed roller 26 comes into contact with the roller 28 in the receive magazine. At this time, the feeding roller 26 is constantly pressed against the roller 28 by the biasing force of a spring (not shown), and has sufficient driving force to feed the photographed sheet film.

A shaft 29 is rotatably supported by a frame 30, and a block 31 that swings when a driving force (arrow L) shown in FIG. 11 is transmitted from the main body of the apparatus is fixed to this shaft.

It is capable of swinging about a shaft 29 in the direction of the arrow shown in FIG.

As mentioned above, the side holding members 36 and 36' serve as guides when the photographed sheet film F is stored in the receive magazine, and the sheet film photographing device body is positioned vertically so that the receiving magazine storage opening faces the floor. When used in an inverted position,
This function is to prevent the previously stored photographed sheet film F' from falling downward due to its own weight, and the sheet metal 37, 37' fixed to the frame 30
It is swingably attached to a shaft 38 which is pivotally supported. The side holding members 36, 36' include a shaft 3.
9 is fixed, and a roller 40 is rotatably attached to the tip of this shaft. When the driving force (arrow L) shown in FIG. 11 is applied from the main body of the device, the block 33 shown in FIG. 9 swings in the direction of the arrow, causing the leaf spring 35 to lift up the roller 40, and In the direction, the side holding members 36, 36' are
Rotates around axis 38. Side holding members 36, 3
6' is always held in the first position by torsion springs 41, 41'.
They are biased in the direction opposite to the arrow in Figure 5, and when the photographed sheet film is stored in the receive magazine, the A, A' sides of the frame 30 and the B, B' sides of the side holding members 36, 36' are on the same surface, making it easy for the photographed sheet film to be stored.

As mentioned above, the front claw 42 also functions to prevent the previously stored photographed sheet film F' from falling downward under its own weight when the main body of the sheet film photographing apparatus is used in an up-down position. In the street
It is fixed to a sliding metal plate 43. The sliding sheet metal 43
is supported by the frame 30 and fixed to a freely sliding sliding shaft 44.

moves downward in FIG. Push plate 47
is always biased upward in FIG. 10 by a torsion spring 58 so as not to impede the progress of the photographed sheet film when it is stored in the receive magazine.

59 is rotatable in the direction of the arrow in FIG. 10, that is, in the direction in which the photographed sheet film is stored.
In order to prevent bounce when the film hits zero, it is a one-way rotating roller that does not rotate in the opposite direction to the arrow, and its surface is made of a material that has a strong frictional force with the film surface. This one-way rotating roller is capable of swinging around a shaft 61, and is always urged by a torsion spring 62 so as to be in contact with the film receiving plate 63. Moreover, by attaching a balance weight 64 that balances the moment with respect to the shaft 61, the same pressing force is applied even when the robot falls vertically as when it is horizontal. 65 (right side in FIG. 10) and 66 indicate guide frames and guide plates when the photographed sheet film is stored in the receive magazine, and 67 indicates the frame 30.
This is a film stopper fixed to the camera to prevent the stored sheet film F' from flying out of the receive magazine.

The operating sequence of the photographed film storage mechanism according to the present invention constructed as described above is shown in FIGS. 9 to 1.
This will be explained using Figure 8.

In FIG. 10, the present receive magazine is attached to the main body of the sheet film photographing device, the magazine lid 23 is opened, and the film feeding roller 26 and guide plate 27 enter the receive magazine from the main body side by a mechanism not shown. The feed roller 26 is in contact with the roller 28 in the receive magazine, and a new photographed sheet film F is stored. Here, both sides of the forward end of the photographed sheet film F in the advancing direction are side holding members 36 and 3 in FIG.
The film enters along the U-shaped portion 6' and stops with the leading end of the film being sandwiched between the one-way rotating roller 59 and the film receiving plate 63.
F' is a photographed sheet film stored before F.

11 and 15 show a state in which the block 31 is actuated by the driving force (arrow L) from the photographing device main body, and the side holding members 36, 36' and the front claw 42 are released. First, when the block 31 is actuated by the driving force from the main body, the lever 33 in FIG. The side holding members 36, 36' rotate in the direction of the arrow in FIG. 15 around , and the photographed sheet film F is released from the U-shaped portions of the side holding members 36, 36'. At the same time, the rotation of the lever 33 causes the sliding shaft 44 in FIG.
By sliding the front claw 42, the front claw 42 can also be released out of the film stopper 67, as shown in FIG.

12 and 16, the state progresses further from the state shown in FIG. 11, and the pushing plate 47 is actuated by the driving force (arrow M) from the photographing device main body, and the photographed sheet film F stored therein is held on the side. Part 3
6, 36' and the front claw 42. Note that the term "downward" here refers to the positional relationship on the drawing. First, when the driving surface from the main body of the device is applied to the resin plate 57 fixed to the pusher plate 47, the pusher plate 47 is pushed down and at the same time, the lever 50 is moved around the shafts 48, 49.
As 51 rotates, the pushing plate 47 moves downward. When the pushing plate 47 is pushed down sufficiently, the stored photographed sheet film F is pushed downward in the figure from the side holding members 36, 36' and the front claw 42, as shown in FIGS. 12 and 16. Pushed in.

13 and 17, the state progresses further from the state shown in FIG. 12, the driving force (arrow L) from the imaging device body is released, and the side holding members 36, 36' and the front claw 42 are moved as shown in FIG. 10. The photographed sheet film F, which has been returned to its original state and stored, is shown stored below the side holding members 36, 36' and the front claw 42 in the figure. As this state progresses further and the driving force (arrow M) from the main body is released, the push plate 47 also returns to the state shown in FIG. 10, and a new photographed sheet film F can be stored. .

Now, when the main body of the sheet film photographing device assumes various postures, in order to be able to store the photographed film, it is necessary to also store the photographed film with respect to the receive magazine in the respective positional relationships shown in FIGS. 19 to 23. It would be nice if it could accommodate film. It is assumed that the lower side in the drawing is the floor side.

Next, Figures 19 to 23 show that it is possible to store new film in the state shown in Figure 10.
Each case in the figure will be described.

In the case of FIG. 19, the direction of the gravity applied to the already stored film F' is the direction that creates a space in the path of the newly stored film F, so that the film is stored smoothly.

In the case of FIGS. 20 and 21, if the already stored film F' falls down or curls, the newly stored film F'
path will be obstructed. however,
The side holding members 36, 36', the front claws 42, and the one-way rotating roller 59 prevent the film from falling or curling, so that storage defects do not occur.

In the case of FIG. 22, the already stored film F' falls in a direction that obstructs the path of the newly stored film F. However, the side holding members 36, 36', the front claws 42, and the unidirectional rotating roller 59 support the four outer sides of the film F' that has already been stored, so that the newly stored film F' is supported. Space is secured for the path of F, and the film is stored smoothly.

In the case of FIG. 23, in addition to the problems that occur in FIGS. 20 and 21, the film that has been stored once falls toward the film feeding roller 26 in the opposite direction from when it was stored, and the film storage opening is blocked. There is a problem with blocking. However, according to the present invention, the unidirectional rotating roller 59 having a strong frictional force acts on the newly stored film F, and prevents the reverse phenomenon. When the number of sheets of film F' accumulates to a certain extent, the weight increases, and the film falls toward the feeding roller 26, leaving one film that is in direct contact with the unidirectional rotating roller. It is firmly supported and does not interfere with the film storage opening. Therefore, also in the case of Fig. 23,
Film is stored smoothly.

Here, only the pressing force of the one-way rotating roller 59 is increased to remove the already stored film.
If an attempt is made to prevent F' from falling to the feeding roller 26 side, the newly stored film F will not advance beyond the one-way rotating roller 59, resulting in storage failure.

A typical example of a sheet film photographing device is shown in Figure 1, which includes a supply magazine 2, an intensifying screen 1
The arrangement of the photographing section 5a and 15b and the receiving magazine 5 is not limited to this. An example of another arrangement is shown in FIG. Components with the same functions as in FIG. 1 are designated by the same reference numerals.

In addition, in this sheet film photographing device, the photographing section is constituted by an intensifying screen, but a type of sheet film that does not use an intensifying screen and forms an image on the sheet film by an optical system, for example, may be used. The photographed film storing mechanism of the present invention can also be used in a photographing device.

As explained above, according to the present invention, when storing a flexible sheet member, even if the sheet storage device is set in an arbitrary direction with respect to the direction of gravity, the already stored sheet member is placed on a new sheet to be stored. The entry of the components is not obstructed, and the components can be reliably stored in the final storage chamber. Therefore, the sheet film imaging device can photograph the subject from any angle, which is beneficial for doctors' diagnosis.
It is extremely large.

Furthermore, the photographed film storage mechanism according to the above embodiment is characterized in that a sufficient space is provided in the storage path for photographed film in the receive magazine. This is particularly effective for sheet film photographing devices in which the film feed speed is very fast, which can lead to troubles such as clogging.
