As can be easily understood from the figure, this conveyance system 86 has a first standby zone 88, a second standby zone 90, and a third standby zone 92 located upstream of the rollers 82. The downstream side of the third standby zone 92 is a large diameter roller 94.96.
facing the conveyance system 98 including.

The downstream side of the conveyance system 98 further includes a conveyance system 1 extending from above to below the casing that constitutes the image reading and recording device 10.
It is configured to face 00.

This conveyance system 100 is composed of a plurality of conveyance roller pairs including the aforementioned conveyance roller pair 24.

Therefore, the image capturing section 12 will be explained below. A ball screw 104 is installed near the roller 96 that constitutes the conveyance system 98.
is rotatably supported in the vertical direction. In fact, the ball screw 104 is retained by a pair of retaining members 106, 108 located at its upper and lower ends. As can be easily understood from FIG. 3, the upper end of the ball screw 104 has a Boo! JIIO is attached to this pulley 11.
A belt 116 is suspended between the pulley 114 which is pivotally attached to the rotary drive shaft of the rotary drive source 112.

Therefore, when the rotational drive source 112 rotates, the belt 11
6, the ball screw 104 rotates.

Then, the photographing table 118 engages with this ball screw 104. In fact, the imaging platform 118 has an internally threaded member 120, 122 that meshes with the ball screw 104;
The casing 124 that constitutes the imaging platform 118 at 0.122
is retained. The casing 124 bulges outward from the outer casing of the image recording/reading device 10 and is used for radiographic imaging of a subject. Although not shown,
A grid or the like is disposed inside the imaging section of the casing 124 to obtain a good radiographic image. However, since this configuration belongs to the prior art, its details will not be discussed here.

Therefore, a pair of rail members 126, 126 are disposed inside the imaging platform 118 so as to be orthogonal to each other in the vertical direction. Pin member 128.13 is attached to rail member 126.126.
0 is engaged and can be displaced in the horizontal direction within the groove defined in the rail member 126. That is, an arm 132 is engaged with the pin member 128 to form a link mechanism, while an arm 134, which is longer than the arm 132, is engaged with the pin member 130. The end of the arm 132 is pivoted approximately at the center of the arm 134.

A bin member 136 is further engaged with the lower end of the arm 134, and holds a holding plate 138 extending vertically between the bin member 136 and the pin member 128.

On the lower end side of the holding plate 138, an elongated portion 140 is carved which is slightly inclined inward with respect to the vertical direction. Holding plate 13
8 has pin members 142 and 144 implanted in its upper and lower parts, respectively, and these pin members 142 and 144 lock the front plate 146 and the rear plate 148 vertically at a predetermined distance. Furthermore, although not shown, coil springs are fitted into the bottle members 142 and 144. Therefore, in a normal state, the front plate 146 is urged in a direction away from the rear plate 148 by the elastic force of the coil spring, but as will be described later,
When the holding plate 138 is pressed against the front surface of the front plate 8, the front plate 146 can be displaced toward the rear plate 148 against the elastic force of the coil spring. Further, below the holding plate 138, a shutter 150 bent in a U-shape is pivotally attached via a swing shaft 152. Therefore, when the distal end portion of the shutter 150 that extends largely in the horizontal direction is pressed, the shutter 150 can swing via the swing shaft 152.

By the way, a short arm 154 is pivotally supported on the arm 134, and this arm 154 is rotatably connected to an arm 158 that is pivotally supported on a rotation drive shaft of a rotation drive source 1560. Furthermore, a separate rotary drive source 160 is disposed below the rotary drive source 156, and a belt 166 is suspended between pulleys 162 and 164 that are pivotally attached to the rotary drive shaft of the rotary drive source 160. The rotational force of the pulley 164
is configured to communicate. Note that the rotational force of the pulley 164 is transmitted to an eccentric cam 168 disposed close to it. Therefore, the rotational force of the rotational drive source 160 ends up rotating the eccentric cam 168.

Further, below the casing 124 is a rotary drive source 170.
is provided, and a link mechanism 172 is engaged with the rotational drive shaft of this rotational drive source 170. Link mechanism 17
2 is connected to an arm 176 that rotates by a shaft 174, and a pressure roller 178 is attached to one end of the arm 176.
is held rotatably. Therefore, the rotational drive source 17
0, the arm 176 rotates via the link mechanism 172, and the pressing roller 178
0, it comes into pressure contact with the rotating roller 182.

In the above configuration, the holding plate 138, the rotary drive source 156, the rotary drive source 160, and the rotary drive source 17
0. The driving roller 180 and the like can be vertically displaced together with the casing 124 under the rotational action of the ball screw 104.

In the figure, reference numbers 184 and 186 respectively indicate the photographing platform 11.
8 shows a winding roller for winding up or unwinding a closing member 190 for closing an opening 188 defined in the image recording/reading device 10 within a movement range of 8.

Therefore, the elongate member attachment/detachment mechanism according to the present invention is as follows:
A mechanism for attaching and detaching a condensing guide consisting of a light guide and a photomultiplier will be explained.

The first side plate 44a that supports the optical unit 42 including the optical surface plate is provided with an internal thread 192, while the second side plate 44b is defined with an opening 194 (FIG. 4C to e). reference). The left and right sides of the side plate 44a144b in FIG. 2 are both in a closed state. Therefore, a guide member 196 is suspended from the upper end of the side plate 44a144b. This guide member 196 has a first sliding member 19
8 and the second sliding member 200 are fitted in a movable manner.

Although not shown, a screw hole is provided below the sliding member 198, and a hole is similarly provided in the sliding member 200. Therefore, the first rod 202 can be screwed into the threaded hole of the first sliding member 198 through the hole of the sliding member 200.

As can be easily understood from the figure, a wire 204 as a suspension means is wound around the distal end of the first rod 202, and the distal end has an I
! 208 is formed.

A male thread 210 is formed at the tip of the second rod 206. On the other hand, the long condensing guide 50 is connected to the light guide section 21.
2 and a photomultiplier section 214. In particular, a first bracket 216 and a second bracket 218 are provided at the upper end of the photomultiplier n214.
is attached.

The image recording/reading apparatus incorporating the elongated member attachment/detachment mechanism according to the present invention is basically constructed as described above, and its operation and effects will be explained next.

Here, as an initial state, one sheet of stimulable phosphor sheet) IP
The front plate 146 and the rear plate 1 are placed at the photographing position in front of the photographing stand 118.
48 and the remaining three stimulable phosphor sheets (IP) are placed in the first to third standby zones 88 and 90, respectively.
．． Assume that there is one in each 92. Therefore, when the rotary drive source 112 is driven in accordance with the height of the subject whose image is to be taken, the boot IJ], 10 rotates via the belt 116, thereby causing the ball screw 10 to rotate.
4 comes to rotate. Since the ball screw 104 is engaged with the internal thread members 120 and 122, the height position of the photographing table 118 can be adjusted under the rotational action of the internal screw members 120 and 122 according to the height of the subject (not shown). During this time, the closing members 190 extend and contract integrally with the photographing platform 118 under the rotational action of the winding rollers 184 and 186, respectively, to open the opening 1.
88 to maintain its interior in a light-shielded state.

When the photographing stage 118 is thus positioned at a suitable position relative to the subject, the stimulable phosphor IP is then fed to the photographing stage 118. Then, the subject is irradiated with radiation from a radiation source (not shown), and a radiation image of the subject is recorded on the stimulable phosphor sheet IP. When the image recording is finished, the photographing platform 118
Then, the rotational drive source 156 is rotationally driven to rotate the arm 158 that constitutes the link mechanism. As a result, arm 1
54 displaces the arm 134 in the direction of arrow A, and accordingly, the pin member 128 is displaced in the direction of arrow B together with the holding plate 138, front plate 146, and rear plate 148. Front plate 1
46 and the rear plate 148 are separated from the front surface of the photographing table 118, the front plate 146 is separated from the rear plate 148 under the action of the unillustrated coil springs of the pin members 142 and 144.
A predetermined space is defined between them.

When the pin member 128 is displaced along the groove of the rail member 126 under the action of the arms 154, 134, and 132, the retaining plate 138, front plate 146, and rear plate 148 move along the two-dot chain line while maintaining a substantially vertical state. Move to the indicated position.

At this time, the pin member 13 implanted in the arm 134
6 is displaced within the elongated hole 140. Of course, shutter 15
0 will also be displaced integrally with the retaining plate 138, and the shutter 150 will move its one end 150a to the eccentric cam 1.
Let's face 68.

Next, the rotational drive source 170 is energized, and the link mechanism 172
The arm 176 is retracted via , and the pressing roller 178 is displaced toward the roller 182 . In the end, shutter 15
The stimulable phosphor sheet I held at the other end 150b of 0
P is held between roller 182 and pressing roller 178.

Here, the rotational drive source 160 is energized and the eccentric cam 168 causes its tip end to reach the one end 150a of the shutter 1.50. As a result, the shutter 150 rotates via the swing shaft 152 of the holding plate 138 in a direction that raises the other end portion 150b. As a result, the holding of the stimulable phosphor IP by the other end 150b is released. Then,
The stimulable phosphor sheet IP is conveyed toward the guide member 22 by rollers 178 and 182.

When the transfer of the stimulable phosphor sheet IF to the guide 6 member 22 side is completed, the rotational drive source 170 is energized, and the pressing roller 178 is separated from the roller 182 via the link mechanism 172 and the arm 176. Further, the rotational drive source 160 is energized, and the tip of the eccentric cam 168 moves away from the position where it presses the one end 150a of the shutter 150, and the shutter 1
The other end 150b of 50 is lowered to form a stimulable phosphor layer (I).
Return to the position where P is held.

Incidentally, the stimulable phosphor sheet IP reaches the image reading section 14 via the transport system 28, the transport system 36, and the curved guide plate 40. In this image reading section 14, the nip roller 46
a is in the raised position via the arm 56.58 under the biasing action of the solenoid 54, and the nip roller 46a is lowered to guide the stimulable phosphor sheet IP to the nip rollers 46a, 46b.

The state is reached where it is held at 48a and 48b. Next, the optical unit 42 is driven, and laser light is irradiated onto the stimulable phosphor IP in the main scanning direction. Nip roller 4
6a, 46b, 48a, and 48b transport the stimulable phosphor sheet (IP) in the sub-scanning direction shown by the arrow, and therefore,
Two-dimensional scanning will be performed on the stimulable phosphor IP.

The stimulated luminescence light obtained by main scanning the laser beam as described above is introduced into the condensing guide 50, converted into an electrical signal via a photoelectric conversion means (not shown), and stored in a storage means (not shown). It turns out. The radiation image of the subject read from the stimulable phosphor sheet IP in this way is read out from the storage means as necessary, and is exposed to a film or the like by a different recording device, or displayed on a CRT or the like. It is possible to do so.

The stimulable phosphor sheet IP whose image information has been read in this way reaches the residual image erasing section 16 along the curved guide plate 62. Therefore, the erasing light source 72 disposed inside the casing 70 is turned on, and the energy remaining in the stimulable phosphor sheet IP is released under the lighting action of this erasing light source 72, and the photographic special equipment section is again turned on. The image will be transferred to the 18 side and will wait for image recording again. During this time, the sirocco fan 74 is energized to forcibly release the heat generated inside the residual image erasing section 16 to the outside.

During this time, the stimulable phosphor sheet (IP) in the third standby zone 92 of the photographic special equipment section 18 is transferred horizontally by the conveyance system 98 under the urging action of the conveyance system 86, and is further curved to the photographing table 111. reach. Of course, at the same time, the stimulable phosphor sheet IP in the second standby zone 90 is transferred to the third standby zone 92.
Also, the stimulable phosphor sheet I in the first standby zone 88
P is transferred to the second waiting zone 90.

Next, the stimulable phosphor sheet IP that has been transferred via the above-mentioned conveyance system 98 and reached the photographing stand falls between the front plate 146 and the rear plate 148 separated by a predetermined interval, and is then moved by the other end 150b of the shutter 150. Stop.

Therefore, the rotational drive source 156 is rotationally driven, and the arm 15
8. The holding plate 138, the front plate 146, and the rear plate 148 are displaced in the direction of arrow C via the arms 154, 134, and 132. That is, the pin member 128 is displaced along the rail member 126, and the holding plate 138, front plate 146, and rear plate 148 reach the front surface of the photographing table 118 while maintaining a substantially vertical state. At this time, the front plate 14 resists the elastic force of the unillustrated coil springs of the bin members 142 and 144.
6 and the rear plate 148 are pressed against the front surface of the photographing table 118 in such a manner as to pinch the stimulable phosphor IP sandwiched therebetween.

Here, as described above, an image is recorded on this stimulable phosphor IP, and the same operation will be repeated thereafter.

Therefore, a procedure for attaching the condensing guide 50 to the side plates 44a and 44b in the above configuration will be explained.

The second rod 206 is inserted through the first bracket 216 and the second bracket 218 of the condensing guide 50. In this case, the tip of the second rod 206 is inserted into the ring 208 of the wire 204. At that time, the first sliding member 198 is the second sliding member 2.
00 side (see Figure 4C). Next, the first rod 202 is turned using a driver, and the hanging ring 208 of the wire 204 is lifted slightly upward together with the second rod 206 and the condensing guide 50 . As a result, the tip of the second bracket 218, which serves as a support and extends upward from the first bracket 216, comes into contact with the first rod 202, and the condensing guide 50 is connected to the ring 208 and the second bracket 218. The bracket 218 is in contact with the first rod 202 and its axial direction is substantially aligned with the guide member 196 and the first rod 202.
The rod 202 and the second rod 206 are in a substantially parallel state.

Therefore, as shown in FIG. 4C, when the first rod 202 is pressed in the direction of the arrow, the first rod 202 and the second
The rod 206 and the condensing guide 50 integrally reach the position shown by the two-dot chain line under the displacement action of the first sliding member 198 and the second sliding member 200 (see FIG. 4C). Next, using the driver again, the first rod 202 is rotated in a direction opposite to the previous time so as to make the wire 204 hang down. As shown in FIG. 4d, the condensing guide 50 is connected to the first bracket 21.
The 6th side gradually descends (see Figure 4C).

Therefore, when the male thread 210 of the second rod 206 reaches the position facing the internal thread 192 of the first side plate 44a, the rotational operation of the driver is stopped. In other words, in this state, the second
The rod 206 and the condensing guide 50 are the guide member 196,
Although it is substantially parallel to the first rod 202, it is spaced apart considerably downward. Next, the light guide is pushed in the direction of the inner thread 192 using one of the hands, and the male thread 210 at the tip of the second rod 202 is screwed into the inner thread 192 using a hand or a screwdriver or the like. Therefore, one end of the light guide 50 is fixed to the internal screw 192, and the other end is held by the second side plate 44b.

The procedure for separating the condensing guide 50 from the first side fN44a and the second side 244b may be performed in the completely reverse order.

According to this embodiment, as described above, in an image recording/reading apparatus in which the side plate and the optical unit held thereon, or the conveyance system, etc. are arranged in close contact with each other, the light condensing guide is provided at one location on the side plate. If an opening is defined that allows sufficient insertion of the condensing guide 50, the condensing guide 50 can be easily and quickly positioned at a predetermined position.

The light guide section 212 of the condensing guide 50 positioned in this way has 27 pairs of rollers 46a, 46b, 48a.

48b, and it becomes possible to read the image on the stimulable phosphor IP expressed by the excitation light.

Although the above embodiment has described a mechanism for attaching and detaching a long photomultiplier in an image recording/reading apparatus, it is of course applicable to the case of attaching and detaching a long member in general.

[Effects of the Invention] According to the present invention, as described above, it is possible to easily and quickly attach a long member even in an extremely narrow space. Therefore, there is no need to bother with complicated work during assembly. Furthermore, it is possible to remove such an elongated member for maintenance purposes, if necessary, even after it has been assembled.
