Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cassette for an image recording carrier, and includes a cassette for holding an image recording carrier such as a stimulable phosphor sheet in a light-tight manner, and a cassette for opening and closing the cassette. A cassette for an image recording carrier comprising a freely disposed lid, and a locking means for closing and fixing the lid to a casing, which can be unlocked by pressing force from various different directions within the device. .

Recently, a radiation image recording and reproducing system that obtains a radiation image of a subject using a stimulable phosphor (stimulable phosphor) has been attracting attention. Here, the storage fluorophore refers to radiation (X-rays, α
When irradiated with rays, β rays, T rays, electron beams, ultraviolet rays, etc., a part of this radiation energy is accumulated, and when excitation light such as visible light is irradiated later, stimulated luminescence light is produced according to the accumulated energy. Refers to the phosphor that is produced.

The radiation image recording and reproducing system described above utilizes this stimulable phosphor, and once the radiation image information of a subject such as a human body is recorded on a sheet having a layer made of a stimulable phosphor (hereinafter referred to as a stimulable phosphor sheet). (or simply referred to as a "sheet"), this stimulable phosphor sheet is scanned with excitation light such as a laser beam to generate stimulated luminescent light, and the stimulated luminescent light is read photoelectrically. An electrical signal is obtained, and based on this electrical signal, a radiation image of the subject is output as a visible image to a recording material such as a photographic light-sensitive material or a display device such as a CRT.

Therefore, in such a radiation image recording and reproducing system, an image reading device for reading a radiation image from a stimulable phosphor sheet on which the radiation image is stored and recorded is specifically configured as follows.

That is, a stimulable phosphor sheet on which a radiation image has been stored and recorded is loaded into the image reading device in a state that it is housed in a cassette, and the stimulable phosphor sheet is taken out from the cassette. Next, the sheet of stimulable phosphor sheet is conveyed to a reading section via a conveyance mechanism such as a belt.

The reading section performs sub-scanning by mechanically transporting the stimulable phosphor sheet in one direction, and also uses light such as a laser beam deflected in a direction substantially perpendicular to the transport direction of the stimulable phosphor sheet. Main scanning is performed by irradiating the beam, and the stimulated luminescence light emitted thereby is detected in time series with a photodetector such as a photomultiplier to obtain image information. Next, the stimulable phosphor sheet after reading is conveyed to an erasing section, and the radiation image remaining on the stimulable phosphor sheet is completely erased by irradiating it with erasing light such as a sodium lamp. are collected in a collection tray.

In this case, the above-mentioned cassette generally consists of a casing that houses the stimulable phosphor sheet and a lid that can be opened and closed in order to take out the stimulable phosphor sheet within the reading device. Become. The cassette is provided with a locking means for preventing the lid from opening relative to the casing except when necessary. That is, if the lid is accidentally opened while a sheet on which a radiographic image is stored and recorded is being transferred to an image reading device, the sheet will be irradiated with external light and, for example, a part of the radiographic image will be erased. Therefore, accurate image reading becomes impossible. Therefore, when transporting a cassette, the lid is firmly locked to the housing via the locking means, and after loading the cassette into the image reading device, the lock release means provided in the device is opened. The stimulable phosphor sheet is removed by releasing the locking means and opening the lid.

By the way, the locking means is generally configured to be released by a pressing force applied from one direction, and the image reading device includes a locking means, for example, at a position corresponding to the tip of the cassette for taking out sheets. It is provided.

However, in this case, the image reading device is equipped with a single-fed mechanism for taking out the sheets from the cassette, a conveyance system for conveying the sheets to the scanning reading section, etc. If the arrangement position of the release means is limited, the arrangement positions of the single wafer mechanism, the conveyance system, etc. will be greatly restricted. As a result, the disadvantage arises that it is impossible to effectively miniaturize the device itself.

In addition, since the position of the lock release means is restricted, for example, the loading position of the cassette cannot be freely selected.
This results in a cassette with extremely little versatility, and the disadvantage is that it is not economical.

Furthermore, even in systems that record radiographic images using conventional X-ray film, the X-ray film on which exposure recording of radiographic images has been performed is loaded into an automatic developing device, etc. while being housed in a cassette shielded from light. , and then removed from the cassette. Therefore, this X-ray film cassette also has the same drawbacks as the aforementioned cassette.

The present invention has been made to overcome the above-mentioned disadvantages, and includes a casing for housing an image recording carrier such as a stimulable phosphor sheet, and an openable/closable lid for holding the image recording carrier in a light-tight manner. By configuring the locking means for fixing the lid body to the casing to be releasable in at least two different directions, the position of the lock releasing means within the device can be freely selected. Therefore, it is an object of the present invention to provide an extremely versatile image recording carrier cassette, which allows the device to be miniaturized easily and allows various loading positions to be selected.

In order to achieve the above object, the present invention comprises a casing that houses an image recording carrier, and an openable and closable lid that holds the image recording carrier in a light-tight manner, the lid being attached to the casing.

At this time, since the second locking members 58a, 58b are formed with inclined surfaces 59a, 59b that are oriented in the vertical direction and inclined, the pressing pins 74a, 74b are displaced upward in the vertical direction, so that the claw members 52a and 52b are displaced in the direction of the arrow against the elastic force of the respective coil springs 60a and 60b (see FIGS. 2 and 3). Therefore,
The locking means 46a, 46b are released, the suction cup 72 constituting the lid opening/closing means is driven, the lid 30 is opened, and the cassette 20 is opened by the reading device 64. In addition, the lid body 30
After opening, the lock release means 70 is driven to displace the respective pressing pins 74a and 74b vertically downward.

Next, the sheet conveyance mechanism 76 is driven. As shown in FIG. 5, when the rotational drive source 96 constituting the swinging means 82 is driven to swing the first link 98a in the direction of the arrow, the second link 98b that engages with the first link 98a is moved. Through this, the arm 92a swings downward about the tenth lug 84, and the conveying row 80 comes into contact with the stimulable phosphor sheet S in the cassette 20. Therefore, when the rotary drive source 90 is driven to displace the drive belt 88 in the direction of the arrow E and rotate the tenth roller 84 constituting the roller pair 78 in the direction of the arrow E, the tenth roller 84 is stretched. The conveying roller 80 rotates in the direction of arrow E via the heald 94 that is rotated. Therefore, the stimulable phosphor sheet S) in sliding contact with the conveyance roller 80 is taken out from the cassette 20 under the rotational action of the conveyance roller 80 and sent to the roller pair 78 side.
The roller pair 78 is held between a 10th lug 84 and a 20th lug 86 that engages with an elastic body (not shown).

In the erasing section 144, a plurality of erasing light sources 146 are turned on, and the irradiation light completely erases the radiation image remaining on the stimulable phosphor sheet S.

The stimulable phosphor sheet S from which the radiation image has been erased by passing through the erasing section 144 is conveyed vertically upward via the conveyor belts 148 and 150 constituting the 51st fl conveying means 147, and then is displaced in the horizontal direction and reaches the sixth conveyance means 154.

The sixth conveying means 154 rotates the conveying direction by 180°.
The biased stimulable phosphor sheet S is stored in a desired sheet storage section 158 of the second stacker 156.

On the other hand, after the stimulable phosphor sheet S is taken out from the cassette 20, the stimulable phosphor sheet 1-S stored in advance in the sheet storage section 158 is sent out from the roller pair 159 to the seventh conveying means 160. This stimulable phosphor sheet S is subjected to secondary erasing via the erasing light source 164 of the auxiliary erasing section 162, and is sent out to the sheet conveying mechanism 76 side.

As shown in FIG. 5, when the rotational drive source 90 is rotated in the direction indicated by the arrow, the tenth ring 84 is rotated in the direction indicated by the arrow via the belt 88 that engages with the rotational drive source 90. Therefore, the stimulable phosphor sheet 1-S held between the pair of rollers 78
is delivered to the cassette 20 side by the rotation of the tenth roller 84. Therefore, when the rotary drive source 96 constituting the swinging means 82 is rotated in the direction indicated by the arrow, the transport roller 80 is rotated through the respective links 93a and 98b as described above.
