Abstract

(57) [Summary] [Purpose] A medical image exposure device with a simple configuration that exposes a medical image at a predetermined position on a sheet film taken out from the insertion slot by inserting a magazine containing a plurality of films into an insertion slot. To obtain a medical image exposure device in which a magazine can be shifted to one side and the magazine can be easily inserted into an insertion port. [Structure] At the bottom inside the insertion port 2, there is a roller 3 that rotates freely. The rotation direction 5 of each roller 3 is determined by the magazine 1
is approximately equal to the insertion direction 4, but is shifted obliquely toward the side surface 6. The side surface 6 also serves as a guide means for regulating the lateral position of the magazine 1.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention allows you to insert a magazine containing many sheets of film, etc. into the insertion slot of the main unit. The sheet film is automatically removed from the magazine inside the main unit. A medical image exposure device that exposes a medical image to a predetermined position on the sheet film. It is related to Especially to ensure that the magazine can be inserted correctly into the specified position in the insertion slot. The present invention relates to a medical image exposure apparatus.

0002

[Conventional technology]

A schematic diagram of the medical image exposure apparatus is shown in FIG. There is a sheet (not shown) in magazine 1. A large number of films (approximately 100 films) are stored one on top of the other. Insert this magazine 1 into the insertion slot. Insert into 2. Then, the shutter 19 of the magazine 1 is opened inside the insertion slot 2. The magazine 1 is opened and the sheet films are taken out one by one from inside the magazine 1. take out The sheet film is transported to a predetermined position within the main unit 20 and used for medical imaging. The image is exposed. In other words, when a medical image displayed on a CRT is photographed or Medical images are directly written using the beam, LED array, etc. In order to facilitate the insertion operation of magazine 1, the insertion slot 2 is larger than the dimensions of magazine 1. It is slightly larger. The magazine 1 is placed inside the insertion slot 2 as shown in Figure 7. a spring 17 provided on one side, and a solenoid 18 as shown in FIG. , it is pushed toward the other side 6 which also serves as a guide means, and is placed inside the insertion opening 2. The horizontal position is determined by Maintaining the correct horizontal position of magazine 1 requires Accurately performs a series of operations such as taking out and transporting sheet film in the device 20. It is essential to carry out.

0003

[Problem that the idea aims to solve]

However, in general, magazine 1 stores a large number of sheet films, and their weight The amount can be as high as about 5Kg. Therefore, the spring 17 is released with a considerably strong force. The magazine 1 must be pushed sideways, so the magazine 1 will not be sprung when inserted. Items that get caught in the ring 18 and are extremely difficult to insert into the insertion slot 2 of the magazine 1 The problem was that it became Also, after inserting magazine 1 into insertion slot 2, The solenoid 18 pushes magazine 1 laterally to align it. Although the insertion operation is not difficult, the solenoid 18 and the It requires an electrical circuit to control it, making the configuration complicated. There was a problem.

0004 This invention was created in view of the above, and its purpose is to provide a magazine with a simple configuration. A medical image exposure system that allows the magazine to be offset and allows for easy insertion of the magazine into the insertion slot. It's about getting a position.

[0005]

[Means to solve the problem]

The medical image exposure device of this invention inserts the magazine at a lateral position perpendicular to the magazine insertion direction. A guide means for regulating the inside of the mouth, and a guide means provided at the bottom of the inside of the insertion port to control the direction of rotation. is an oblique direction that is approximately equal to the magazine insertion direction and offset to one side. It is configured with a

[0006]

[Effect]

When the magazine is inserted into the insertion slot, the rollers rotate in the insertion direction. How to rotate the roller Since the direction is diagonal and shifted to one side, it is inserted by rolling on top of it. Magazines are shifted to one side.

[0007]

【Example】

An embodiment of the present invention will be described with reference to FIG. In the figures, the same numbers as in Figures 6 to 8 The numbers have the same meaning. At the bottom of the inside of the insertion port 2, there is a hole provided on the bottom surface 9. There is a roller 3 that rotates freely with a part of it coming out into the insertion opening 2. Roller 3 is the rotating shaft Three sets of four rollers having a common roller are arranged along the insertion direction 4. . As shown in FIG. 2, the rotation direction 5 of each roller 3 in the insertion opening 2 is is substantially equal to the insertion direction 4, but is deviated diagonally by about 5° toward the side surface 6. The side surface 6 is caused by the insertion direction of the magazine 1 due to a deviation in the rotational direction 5 of the roller 3. This prevents the magazine from shifting endlessly in the horizontal direction perpendicular to direction 4. It also serves as a guide means for regulating the directional position.

[0008] When magazine 1 is pushed and inserted into insertion slot 2, the bottom surface of magazine 1 contacts roller 3. The contact roller 3 rotates. The direction of rotation of the roller is an oblique direction shifted to one side 6. Since the magazine 1 is inserted by rolling on it, it faces the side 6. It's biased. Magazine 1 is pushed to one side and shifted laterally as it is inserted. lateral slip between the bottom surface of the magazine 1 and the roller 3 from the time it hits the side surface 6. occurs, and the horizontal movement of the magazine 1 is stopped. Magazine 1 is inserted into the specified slot of insertion slot 2. inserted until the position is reached. While the magazine 1 is moving in the insertion direction 4, the low Since it is always pushed towards side 6 by Ra 3, after hitting side 6, the Gin 1 is always in contact with side surface 6, and its lateral position is always fixed. Determined by

[0009] Such an implementation eliminates the need for powerful solenoids or electrical circuits, and reduces the The magazine 1 can be shifted to one side with a simple configuration of the roller 3 and the guide means. Also, There is no element such as a ring that constantly applies force to magazine 1, and the magazine is inserted in direction 4. Inserting the magazine 1 is extremely easy as the force pushing the magazine 1 is used to shift the magazine to one side. It is. Also, since roller 3 is used, inserting magazine 1 itself is not necessary. Only a small amount of force is required, making insertion extremely easy.

0010 The present invention is not limited to the above embodiments. In the example, four rows with a common rotation axis are used. However, as shown in Figure 3, one large roller is provided with multiple sets. It may be something. In addition, as shown in Figure 4, individual rollers that do not have a common rotation axis may be placed. In addition, in the above embodiment, the measuring surface 6 also served as a guide means, but As shown in FIG. may be provided to limit the lateral position. Furthermore, in the above embodiment, the low La 3 rotates freely, but when inserting or removing magazine 1, It may be one that rotates by itself in either direction of rotation. In addition, in the above embodiment, the roller 3 had a part coming out from the hole in the bottom 9, but the plate in the bottom 9 was missing and the roller 3 may be entirely exposed.

[0011]

[Effect of the idea]

The medical image exposure device of this invention inserts the magazine at a lateral position perpendicular to the magazine insertion direction. A guide means for regulating the inside of the mouth, and a guide means provided at the bottom of the inside of the insertion port to control the direction of rotation. is an oblique direction that is approximately equal to the magazine insertion direction and offset to one side. Since the configuration is equipped with a A magazine can be inserted.
