In this apparatus having the above-mentioned configuration, the process for reading the image information stored and recorded on the stimulable phosphor sheet 1 will be explained first.

A cassette 2 in which radiography was performed on a stimulable phosphor sheet held inside an external imaging device (not shown)
The stimulable phosphor sheet supply unit 10 is loaded with the stimulable phosphor sheet. This cassette 2 has a light-shielding property to prevent the sheet from being exposed to external light when recording (photographing) image information by irradiating the stimulable phosphor sheet l with radiation. It consists of a cassette main body 2a for storing a phosphor sheet 1 and a lid part 2b that can be opened and closed. This lid part 2
b is closed when the cassette 2 is loaded into the stimulable phosphor sheet supply section 10, but inside the stimulable phosphor sheet supply section 10, the stimulable phosphor sheet 1

The stimulable phosphor sheet 1 is held in the cassette 2 so that the front surface on which the stimulable phosphor layer is formed faces down.

The optical scanning section 40 scans the stimulable phosphor sheet 1 on which image information has been accumulated and recorded with a laser beam 41, and the sheet 1 excited by the scanning. The stimulated luminescent light emitted from the photomultiplier is photoelectrically read by a stimulated luminescent light detecting means 42 such as a photomultiplier to generate an electrical image signal for outputting a visible image. In the figure, 43 is an example of a He-Ne laser light source, 44 is an optical deflector such as a galvanometer mirror,
Reference numeral 45 refers to a light guide 42a of a photoelectric reading means (the light guide t''42a
is a reflecting mirror that totally reflects the stimulated luminescence light and reflects it toward a photodetector 42b such as a photomultiplier. Note that the optical modulator 46 such as AOM
The operation is stopped when the laser beam 41 scans the stimulable phosphor sheet 1.

The stimulable phosphor sheet 1 carried into the optical scanning section 40 is transported in the direction of arrow A7 by the stimulable phosphor sheet transport means 70, and the stimulable phosphor sheet 1 is transported by the laser beam 41 deflected approximately perpendicular to this transport direction. The entire surface is scanned two-dimensionally to generate stimulated luminescence light, which is detected by the photodetector 42b via the light guide 42a. In the photodetector 42b, the stimulated luminescent light is converted into an electrical signal, and the obtained electrical signal is sent to the image information processing circuit 47.
After being sent to the computer and subjected to image processing, it is stored in the memory 48. In this embodiment, the stimulable phosphor sheet conveying means 70 in the optical scanning section 40 serves as a sub-scanning means.

In addition, when reading radiation image information, reading to obtain image signals for visible image output as explained above (main reading)
Prior to this, pre-reading is performed to read the outline of the radiation image information stored and recorded on the stimulable phosphor sheet, and based on the image information obtained by this pre-reading, the reading conditions etc. for performing the main reading are determined. However, a method of performing the main reading according to the reading conditions is known.

As a method for performing such pre-reading, for example, the stimulable phosphor sheet 1 is scanned using excitation light with an energy lower than that of the laser beam (excitation light) used for the above-mentioned main reading, and the luminance emitted by this scanning is There is a method of reading the stimulated luminescent light using a stimulated luminescent light detecting means (for example, the method disclosed in Japanese Patent Application Laid-Open No. 58-67240).

The optical scanning section in the present invention may be a section that performs both main reading and pre-reading in addition to the above-mentioned section that performs only main reading. For example, the stimulable phosphor sheet 1 is transported in the direction of arrow A, pre-reading is performed, and then the stimulable phosphor sheet is transported back in the direction of arrow A8 by switchback, returned to the reading start position, and then read again in the direction of arrow A. It is only necessary to convey the paper in the direction of the paper and perform the main reading. Note that the optical members disposed in the optical scanning section are not limited to those described above; for example, a long photomultiplier is disposed along the main scanning line as a stimulated luminescence light detection means, and Exhaustive light may also be detected (see Japanese Patent Application No. 80-156255, etc.).

The erasing section 100 is for erasing the radiation image information remaining on the stimulable phosphor sheet 1 after the reading is completed (for causing the stimulable phosphor to emit the remaining radiation energy). That is, some of the radiation image information stored and recorded on the stimulable phosphor sheet 1 still remains on the stimulable phosphor sheet 1 after being read, and in order to reuse this stimulable phosphor sheet 1, This residual image information is erased in the eraser 100. The erasing unit 100 in this embodiment includes a fluorescent lamp and a tungsten lamp.

An erasing light source 101 such as a sodium lamp, a xenon lamp, an iodine lamp, etc. is provided, and the stimulable phosphor sheet 1 is transported in the direction of arrow A1 while being exposed to these erasing light sources 10.
The residual radiation energy on the stimulable phosphor sheet 1 is emitted upon being irradiated with light by the stimulable phosphor sheet 1. Note that the erasing method in the erasing unit 100 may be any known method, and erasing may be performed using heating or a combination of light irradiation and heating.

The stack section 120 includes a stimulable phosphor sheet supply section 1
In order to efficiently carry out the stimulable phosphor sheet 1 from the stimulable phosphor sheet supply section 10 and carry it into the stimulable phosphor sheet supply section 10, The stimulable phosphor sheet 1 and the erased stimulable phosphor sheet 1 before being carried into the stimulable phosphor sheet supply section LO are temporarily stored and kept on standby.

The stack unit 120 is constituted by a stacker 121, and the stacker 121 includes a plurality of stimulable phosphor sheet storage chambers 123 partitioned by partition plates 122,
The nearby belt conveyor 13 moves up and down in the direction of arrow E in the figure.

The sheet 1 is placed in the predetermined stimulable phosphor sheet storage chamber 12.
3. After the rear end of the stimulable phosphor sheet 1 leaves the belt conveyor 136, the stimulable phosphor sheet 1 falls under its own weight, and is held with its leading end in contact with the stopper 124 in the stimulable phosphor sheet storage chamber 123. When taking out the stimulable phosphor sheet 1 from the stacker 12L, after moving the stacker 121 up and down so that the desired stimulable phosphor sheet storage chamber 123 is adjacent to the belt conveyor 138, move the stopper 124 to the arrow F. The stimulable phosphor sheet 1 is pushed up by moving the stimulable phosphor sheet 1 in the direction shown in FIG.

Reading image information in the optical scanning section 40 and erasing residual image information in the erasing section 100 take a relatively long time. , Is it necessary to take out the stimulable phosphor sheet 1 from the cassette 2, read it, erase it, and put it back into the cassette 2 for a long time, during which time the next cassette needs to be kept waiting outside the device? If the stacker 121 is provided as described above,
Even if the preceding stimulable phosphor sheet 1 is being read, the stimulable phosphor sheet 1 can be immediately taken out from the cassette 2 and stored in the stacker 121. A suitable stored stimulable phosphor sheet 1 that has been erased can be loaded immediately, and the waiting time for the cassette outside the apparatus can be shortened.

Next, the processing of the film 3 on which the radiation image has been recorded will be explained.
