Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an electron microscope, and more particularly to a magazine for storing recording media for an electron microscope that stores recording media from above and takes them out from below.

[Conventional technology]

Conventionally, the feed magazine for storing unshot film and the receiver for storing shot film were placed on the same plane in the camera chamber, and the unshot film was taken out from the opening in the top cover of the feed magazine and transported to the closing position. The post-shoot receiver stored the film that had been shot through the opening in the top cover of the magazine.

FIG. 6 is a diagram showing the camera room of such a conventional electron microscope, in which 1 is a feeding magazine, 2 is a receiving magazine, 3 is unphotographed film, 4 is photographed film, 5 is a spring, 6 is a table, 7 is a table support member, 8 is a trolley, 9 is a claw, lO
is the rail, 11 is the motor, 12.13.14.15.1
6 is a gear, and 17 is a link.

In the figure, a feed magazine 1 containing unphotographed films and a receiver containing photographed films are placed on the same plane in a camera chamber where the magazine 2 is in a vacuum state during photographing.

Since the unshot film 3 is easily bent, it is placed in a metal cassette. Further, within the feed magazine 1, the unphotographed film 3 is constantly pushed upward by a spring 5. table 6
is placed at the photographing position and moves up and down as the table support member 7 swings. Further, the trolley 9 moves linearly on the rail 10 by the link 17 as the gears 12, 13, 14, 15 rotate due to the rotation of the motor 11, and the gear 16 revolves like a planetary gear. This cart 9 is provided with a claw 8 for hooking a film-containing cassette.

In such a configuration, when photographing, by driving the motor, the gears 13 to 16 rotate, the link moves linearly, the claw 8 of the trolley 9 pulls out the unphotographed film 3 of the feed magazine 1, and the table 6 set on top. After shooting, the table support member 7 rotates counterclockwise from the position shown in the figure to lift up the table 6, and in this state, by moving the cart to the right, the claw 8 transports the shot film to the magazine 2. and store it.

By sequentially repeating this operation, exposed films can be stored in the magazine 2 one after another.

[Problems to be solved by the invention]

In this way, with conventional magazines for storing photographic film,
Since the film-containing cassette is pulled out and stored through the opening in the top cover of the magazine, the cassette has to be pushed upwards inside the feed magazine, making the magazine larger and having poor operability. Furthermore, the feeding magazine and receiver had specialized magazine functions.

This type of structure was used for highly rigid metal film cassettes used to prevent photographic film from bending when the camera room was evacuated. In the case of ultra-high-sensitivity recording media such as imaging plates, which use flexible resin cassettes, the recorded information is read by irradiating laser light while the cassette is in the cassette, without having to be removed from the cassette and subjected to development processing. A new recording medium storage magazine and a transport device suitable for it are required.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a magazine for storing recording media for an electron microscope that can be made compact and in which the feeding magazine and the receiver can be shared in the magazine.

[Means for solving problems]

To this end, the storage magazine for recording media for an electron microscope of the present invention is a magazine for storing recording media for an electron microscope that records an electron beam image obtained by irradiating a sample with an electron beam emitted from an electron gun on a recording medium. The apparatus is characterized by comprising an openable and closable upper lid for storing a recording medium, an opening provided at the lower part of an openable and closable side surface for feeding out the recording medium, and a feeding means for sequentially feeding out the recording medium from the opening.

[Function] The magazine for storing recording media for an electronic AM mirror of the present invention has an openable and closable upper lid that stores the recording medium, an opening provided at the bottom of the openable and closable side surface through which the recording medium is sent out, and a storage medium that allows the recording medium to be inserted through the opening. By providing a feeding means for sequentially sending out the magazine, the feeding magazine and the receiver can be shared by the magazine with the same structure, and recording media can be stored in the order of shooting from the opening in the top cover and taken out in the order of shooting from the opening at the lower side.

I close the magazine entrance to the camera room and prepare to shoot.

A solenoid valve is actuated in response to a command from the operation panel, the eccentric cam 23 is rotated, and the unphotographed film is sent out via the feed claw 24, and the unphotographed film is conveyed to the photographing position by a film conveying device to be described later and photographed. After shooting,
Once the film has been shot, it is returned and the open case is stored in the magazine.

Further, it is also possible to add an automatic opening/closing device to the film transport device so that the light shielding plate 22 and the receiver of the feeding magazine can automatically open and close the top cover 21 of the magazine.

Next, an example of use of the recording medium storage magazine of the present invention will be explained.

The door 37 is attached via a gasket 38, and the interior of the camera room main body 32 is kept in a vacuum during shooting. The conveyance device 34 carries an unshot film 39 in the camera room.
is taken out from the feeding magazine 35, and after shooting at the shooting position, the film 40 is taken out, and the receiver is transferred from the shooting position to the magazine 3.
6.

In FIG. 3, a set of two rollers 41 hold both edges of the cassette of unphotographed film 39 pushed out from the feed magazine.
Then, it is pulled further forward from above and below, and is sandwiched between parallel links 48 made up of rollers 44 and belts 45. The belt 44 is structured to sandwich both edges of the cassette from above and below. The rollers 41 and 44 are each gear 4.

Further, as shown in FIG. 5, it is also possible to make the light shielding plate 55 rotatable.

〔Effect of the invention〕

As described above, according to the present invention, recording media can be stored through the opening in the top cover of the magazine and taken out from the opening at the bottom, and the magazine can be shared between the feed magazine and the receiver. Since no projection is required for feeding, it can also be used in resin cassettes used for ultra-high sensitivity recording media such as imaging plates. Further, since the receiver allows photographed recording media to be taken out from the bottom of the magazine, it is more convenient for ultra-high-sensitivity recording media that need to be read by a reading device in the order in which they are photographed. Furthermore, by using a resin cassette,
Sliding friction when removing and transporting cassettes is reduced,
It is possible to significantly reduce photographing interference caused by metal powder, eliminate the need for a spring to push up a recording medium that has not been photographed, and the magazine can be made smaller accordingly.
