Description

  The present invention relates to a packaging member for a device having a moving caster at the bottom of a main body.

  In order to transport and transport various devices, it is necessary to lift the device once when packing the device with the packing material and installing the packed device at the installation location. This will lead to increased installation costs and time. For this reason, the thing which attached the slope (inclination) to the pallet etc. which are the foundations of a packing member is well-known as follows.

  The following Patent Document 1 discloses a loading platform assembly such as a printer used for a shipping container, and the loading platform assembly is transported in a state where four cargo supports are positioned between a loading platform base and a printer, and the printer is demanded. When installing the printer, the cargo support is inverted and attached to the base of the loading platform to form a ramp for loading and unloading the printer (see FIGS. 3 and 4).

The following Patent Document 2 discloses an article transporting pallet that can be used as a pallet with an inclined table, and a digit member composed of two slope members obtained by dividing a rectangular columnar member into two parts of both deck boards of the article transporting pallet. In the unloading operation, the digit member is pulled out from the opening support part, and the pair of slope members face each slope up and the higher end of the slope is the end of the pallet. A product conveyance ramp is formed by arranging the parts in correspondence with the distance between the casters of the product (see FIG. 1).
JP-A 61-69567 JP 2004-256113 A

However, according to the structure that forms the ramp of the conventional example, as shown in FIG. 6, when the box-shaped device body D0 with casters Y is moved from the pallet P to the installation surface G for installation, When the apparatus main body D0 hits both the ramp S and the pallet P, the bottom D1 of the apparatus main body rubs and cannot move. In order to avoid such problems, (1) the height of the wooden pallet P is lowered.
(2) Make the slope S as shallow as possible.
(3) Increase the caster Y diameter.
(4) Reduce the distance between casters Y.
However, none of these are appropriate measures for the following reasons.

(1) Regarding the height of the pallet P, the wooden pallet needs to have a thickness that allows the claw of the moving forklift to be inserted. Therefore, the minimum thickness is determined and cannot be made very thin.
(2) To make the angle of the ramp S gentle, the ramp becomes too long and the installation space becomes large, and the packing volume also becomes large.
(3) The overall height of the device body is increased.
(4) It may become unstable during movement or use due to the relationship with the center of gravity.

  SUMMARY OF THE INVENTION In view of the above-described problems of the prior art, the present invention provides a package that can stably install the apparatus main body in a small space without reducing the inclination angle of the ramp and increasing the overall height of the apparatus main body. An object is to provide a member.

  In order to achieve the above object, a packaging member according to the present invention is a packaging member for a device having a moving caster at the bottom of the main body, and a pallet for transporting the device, and a first base for supporting the device main body, The bottom portion is provided on the first base, engages with at least two opposing sides of the bottom of the apparatus main body, is detachable, and the caster is separated from the first base. A first buffer member that supports the first pallet; a second buffer member provided between the pallet and the first base; and a second buffer member provided between the pallet and the first base; A support assembly having substantially the same height as the second buffer member, and the support assembly is detachable from the pallet. The removed support assembly includes the second buffer portion. Characterized in that it is configured to be engaged with the said pallet at a tilt angle continuous with the first inclined angle of the base which is supported by the pallet.

  According to this packing member, when the apparatus main body is taken out from the packing member and installed, if the first buffer member is removed, the caster of the apparatus main body comes in contact with the first base and the support assembly is removed from the pallet. And the first base supporting the apparatus main body is inclined on the pallet, and the support assembly is engaged with the pallet at an inclination angle continuous with the inclination angle of the inclined first base supported by the pallet. The first base and the second base of the support assembly are inclined at substantially the same inclination angle to form an inclined path, and the tip of the second base is in contact with the installation surface. Therefore, the apparatus main body can be stably and easily moved to the installation surface on the first and second bases inclined by the casters. Thus, it is not necessary to increase the caster diameter attached to the apparatus main body without reducing the inclination angle of the ramp, and it is not necessary to increase the overall height of the apparatus main body, and the apparatus main body can be installed in a small space.

  In the packing member, the support assembly may be configured such that the third buffer against the second base when the apparatus main body is supported on the pallet and when the support assembly is engaged with the pallet after the removal. It is preferable that the position of the member is configured to be changeable. By changing the position of the third buffer member, the second base can be tilted at substantially the same tilt angle as the first base.

  Note that the image reading apparatus previously proposed by the present applicant in Japanese Patent Application No. 2004-362861 is loaded with a cassette containing an image accumulator from above in the vertical direction to read an image from the image accumulator, thereby suppressing the overall height of the apparatus main body. (It is preferable to keep the height from the floor within 700 to 710 mm assuming an average height of 170 cm (Japanese)). If the diameter of the caster is increased, the effect of cassette loadability due to the suppression of the overall height will be lost. On the other hand, in the present invention, as described above, the image reading apparatus main body can be stably moved for installation without increasing the overall height of the apparatus main body.

  According to the packaging member of the present invention, the apparatus main body can be stably installed in a space-saving manner without reducing the inclination angle of the ramp and without increasing the overall height of the apparatus main body.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a side view showing a main part of a packaging member according to the present embodiment. FIG. 2 is a side view showing a state where the support assembly is removed from the packaging member of FIG. FIG. 3 is a side view showing a state where the support assembly is attached to the packing member of FIG. 2 while being inclined. FIG. 4 is a plan view showing a first base and a first buffer member of the packaging member of FIG. FIG. 5 is a plan view showing a second buffer member and a support assembly of the packaging member of FIG.

  As shown in FIG. 1, the packaging member 10 of the present embodiment is for packaging a relatively heavy box-shaped device main body D0 having a moving caster Y at the bottom of the main body for transportation.

  The packaging member 10 of FIGS. 1 to 3 includes a wooden pallet 17 for carrying an apparatus into which a forklift claw can be inserted and withdrawn, a plate-like first base 12 that supports the apparatus body D0, It is provided on the base 12, is engaged with two opposing sides of the substantially rectangular bottom D 1 of the apparatus main body D 0, is formed to be detachable by rotating, and the caster Y is separated from the first base 12. The first buffer member 11 capable of supporting the bottom portion D1, the second buffer member 13 provided between the pallet 17 and the first base 12, the pallet 17 and the first base 12, And a support assembly 16 further provided therebetween.

  As shown in FIG. 4, the first buffer member 11 is composed of four relatively small plate-like members, is rotatable around the rotation shaft 11 a, and is arranged at the four corners of the rectangular first base 12. Yes.

  When the first buffer member 11 is positioned at the four corners of the first base 12 as indicated by the solid line in FIG. 4, the apparatus main body D0 indicated by the alternate long and short dash line is supported and fixed at the corner where the caster Y is not positioned (see FIG. 1). In addition, when the apparatus main body D0 is installed, if the first buffer member 11 is rotated about the rotation shaft 11a, the first main body 12 comes out of the four corners of the first base 12 as shown by the broken line position, and the apparatus main body D0. Is not supported at the bottom D1 by the first buffer member 11, but the caster Y of the apparatus main body D0 is placed on and supported by the first base 12.

  As shown in FIGS. 1 and 5, the support assembly 16 includes a plate-like second base 15 and a third buffer member 14, and has substantially the same height as the second buffer member 13. As shown in FIG. 2, the pallet 17 can be removed by being pulled out in the horizontal direction H from the front surface D2 side of the apparatus main body D0.

  As shown in FIG. 5, the support assembly 16 is divided into two along the front surface D <b> 2 side of the apparatus main body D <b> 0 indicated by the alternate long and short dash line, and the second base 15 includes the buffer members 14, 14. A concave grip 18 is formed therebetween. When the support assembly 16 is pulled out as shown in FIG. 2, the operator can easily pull it out by gripping the second base 15 with the grip portion 18. The second buffer member 13 is also divided into two along the back surface D3 side of the apparatus main body D0.

  Each buffer member 14, 14 is detachable and can be moved in the direction H 'of FIGS. 2 and 5 to change its position. The buffer members 14 and 14 are located between the second base 15 and the installation surface G when the support assembly 16 is inverted as shown in FIG. When the apparatus main body D0 is moved, the deflection (deformation) of the second base 15 is prevented.

  Further, as shown in FIGS. 1 and 5, the second base 15 of the support assembly 16 is provided with a pair of small projection-like engaging pins 19 and 19 at one end on the second buffer member 13 side. The support assembly 16 is inverted as shown in FIG. 3 and then inserted into an engagement hole 17a (FIGS. 2 and 3) formed in the pallet 17 to engage with the second inclined portion. Deviation of the base 15 can be prevented.

  As described above, according to the support assembly 16, the first base 12 is inclined on the pallet 17 by pulling out the support assembly 16, and the device is packed on the pallet 17 into which the forklift claw can be inserted. The body D0 can be switched between horizontal and inclined.

  Further, when the apparatus main body D0 is packed with the packing member 10 as shown in FIG. 1, the caster Y of the apparatus main body D0 is separated from the first base 12 by the first buffer member 11 (at the position of the solid line in FIG. 4). Since the second and third buffer members 13 and 14 are made of an elastic material such as a porous material such as a rubber material or polyurethane, the packing member 10 can be used as a transportation vehicle for the apparatus main body D0. It has a structure in which vibrations and impacts are difficult to be transmitted to the apparatus main body D0 during transportation or loading / unloading by transportation means.

  When the apparatus main body D0 is taken out from the above-described packing member 10 and installed at a predetermined position, the caster Y of the apparatus main body D0 becomes the first when the first cushioning member 11 of the packing member 10 is rotated as shown by the broken line in FIG. 1 in contact with the base 12.

  Next, when the support assembly 16 is removed from the packaging member 10 as shown in FIG. 2, the first base 12 that supports the apparatus main body D0 is inclined on the pallet 17 with the second buffer member 13 side up. .

  Next, after the third buffer member 14 of the support assembly 16 is shifted on the second base 15 and the support assembly 16 is reversed, the support assembly 16 is at one end of the second base 15 as shown in FIG. The engagement pins 19 are engaged with the engagement holes 17a of the pallet 17, and the second base 15 is inclined and supported by the installation surface G at the other end. The inclined second base 15 is supported by the third buffer member 13 at an intermediate position.

  4 may be removed after the support assembly 16 is removed, and a part of the first buffer member 11 may be removed. It may be performed after the removal.

  As described above, the first base 12 is inclined on the pallet 17 with the apparatus main body D0 placed thereon, and the second base 15 of the removed support assembly 16 is the first base 12. It inclines with the inclination angle which continues to the inclination angle. In this way, the first base 12 on which the apparatus main body D0 is placed and the second base 15 form a continuous slope SS as shown in FIG. 3, so that the bottom D1 of the apparatus main body D0 is conventional. The apparatus main body D0 can be easily and stably moved to the installation surface G in the direction I of FIG.

  Further, since it is not necessary to reduce the inclination angle of the ramp SS between the first base 12 and the second base 15, a space on the installation surface G is not so much required, and the apparatus main body D0 is saved in space. Can be installed.

  Further, since it is not necessary to increase the diameter of the caster Y attached to the apparatus main body D0, it is not necessary to increase the total height h (FIGS. 1 and 3) of the apparatus main body D0. As a result, it is possible to avoid an increase in the size and cost of the apparatus due to the enlargement of the caster C. For example, in an image reading apparatus in which a cassette is inserted from above in the vertical direction, the operability deteriorates when the apparatus is used. Can be prevented.

  1 to 3, for example, the depth dimension a of the apparatus main body D0 is 370 mm, the distance b in the depth direction of the casters Y is 300 mm, the height c of the second buffer member is 40 mm, and the casters Y of FIG. The gap with the first base 12 can be 9 mm, and the inclination angle of the slope SS can be 6 degrees, but these are examples and can be set to other dimensions.

  Next, an image reading apparatus will be described with reference to FIGS. 7 to 18 as an example of a preferable apparatus main body D0 packed with the above-described packing member 10.

  FIG. 7 is a perspective view schematically showing the appearance of the image reading apparatus according to the present embodiment. FIG. 8 is an exploded perspective view schematically showing a cassette that can be attached to and detached from the image reading apparatus shown in FIG.

The back plate 92 and the front plate 91 are separated as shown in the figure and can be combined as indicated by the broken line in the figure, and locked after the combination.

  A cassette 90 in which the back plate 92 and the front plate 91 are combined and locked is inserted into the image reading apparatus 100 in FIG. 7 from the upper side in the extension direction to the insertion port 23 while being guided by the convex portion 25 and the plurality of rollers 31. . The image information stored in the photostimulable phosphor sheet 93 is read after the back plate 92 and the front plate 91 are separated after unlocking in the image reading apparatus 100.

  Next, a configuration inside the housing 101 will be described with reference to FIG. FIG. 9 is a cross-sectional view of the case of FIG. 7 cut along the direction of the dashed line IX-IX.

  As shown in FIG. 9, a barcode reader 35 that reads the barcode of the cassette 90 is provided near the insertion slot 23. Below the insertion opening 23, a lifting platform 41 on which the inserted cassette 90 is placed is provided. The lifting platform 41 is provided so as to be movable in the vertical direction by a guide member extending vertically in the housing 101, and the power of the lifting motor 42 is transmitted to the lifting platform 41 via the pulley 43 and the endless belt 44, etc. The table 41 moves up and down. The cassette 90 is also moved up and down by the vertical movement of the lifting platform 41.

  Two guide portions 51 are provided below the insertion port 23 so as to face each other in the left-right direction. The two guide portions 51 are provided so as to be able to contact and separate from each other in the left-right direction, and the power of the width adjusting motor 52 is transmitted to the guide portion 51 via the pulley 53 and the endless belt 54, so that the guide portion 51 moves to the left and right. To do. In particular, the front plate 91 of the cassette 90 placed on the lifting platform 41 is sandwiched between two guide portions 51 that are close to each other, and the position in the left-right direction is adjusted. On the other hand, when the guide portions 51 are separated from each other, the clamping of the cassette 90 is released. Note that the lifting platform 41 or the guide portion 51 is provided with a lock release mechanism for releasing the engagement of the engaging portion of the cassette 90.

  FIG. 10 is a perspective view showing the inner structure of the housing 101 and showing the front, top and left sides of the structure behind the elevator 41. FIG. 11 is a perspective view showing the inner structure of the housing 101 and showing the back, top, and left sides of the structure behind the elevator 41. FIG. 12 is a perspective view showing the front, top, and left side of the link mechanism 65 in an open state.

  As shown in FIGS. 9, 10, and 11, a moving plate 61 is disposed behind the elevator 41 and the guide portion 51, and a magnet 60 is attached to the front surface of the moving plate 61. A through hole 62 is formed in the upper part of the moving plate 61, and a guide column 64 is inserted into the through hole 62. The guide column 64 is erected so as to protrude forward from the upper part of the frame 63 fixed to the housing 101 on the rear side in the housing 101, and the moving plate 61 is guided by the guide column 64 to move forward and backward. It is possible to move to.

  The moving plate 61 can be moved back and forth in a state parallel to the back surface of the housing 101 by the link mechanism 65. That is, as shown in FIGS. 10 to 12, the link mechanism 65 includes a link piece 66, two link pieces 67, two shaft members 68, a shaft member 69, and two sliding members disposed behind the movable plate 61. The moving shaft 70 is composed of a shaft member 71 and two sliding shafts 72.

  The intermediate portion of the link piece 67 is rotatably connected to the intermediate portion of the link piece 68 by the shaft member 68, and one end portion of the link piece 67 is rotatably connected to the upper portion of the frame 63 by the shaft member 71. The other end is connected to the lower part of the moving plate 61 by a sliding shaft 72 so as to be movable up and down.

  One end portion of the link piece 66 is rotatably connected to the upper portion of the moving plate 61 by a shaft member 69, and the other end portion of the link piece 66 is connected to the lower portion of the frame 63 by a sliding shaft 70 so as to be vertically movable. ing.

  A moving body 73 is connected to the other end of the link piece 66, and the other end of the link piece 66 is rotatable about a left-right axis with respect to the moving body 73. The moving body 73 is screwed into a ball screw 74 extending in the vertical direction, and the ball screw 74 is attached to the frame 63 so as to be rotatable about its axis. A worm wheel 75 is provided at the upper end of the ball screw 74, and a worm 76 is engaged with the worm wheel 75, and the worm 76 is directly connected to a power take-off shaft of a motor 77.

  When the moving plate 61 is moved forward by the motor 77 and the link mechanism 65, the back plate 92 of the cassette 90 placed on the lifting platform 41 is attracted to the magnet 60, and the moving plate 61 thereafter moves backward. As a result, the back plate 92 moves rearward together with the moving plate 61.

  Next, the scanning type image reading head 80 will be described with reference to FIGS. 9 and 10. The image reading head 80 is provided between the frame 63 and the lifting platform 41 and is moved in the left-right direction by a linear motor 81. A scanning excitation light irradiation mechanism and a photodetector are provided in the case 82 of the image reading head 80 shown in FIGS. 9 and 10, and an erasing light irradiation unit is attached to the case 82.

  The scanning excitation light irradiation mechanism includes a laser diode, a collimator lens, a polygon mirror, a reflecting mirror, a cylindrical lens, a motor, and the like. The scanning excitation light irradiation mechanism irradiates laser light in a wavelength band that excites the stimulable phosphor sheet 93 backward, and moves the laser light irradiation position in the vertical direction. The photodetector includes a light guide, a condenser tube, a light receiving sensor, and the like. The photodetector receives the stimulated emission light emitted from the photostimulable phosphor sheet 93 within the irradiation range (scanning range) of the scanning excitation light irradiation mechanism and performs photoelectric conversion of the received light. The erasing light irradiating unit irradiates the erasing light in the wavelength band for erasing the radiation energy of the stimulable phosphor sheet 93 backward.

  Next, a usage method and operation of the image reading apparatus 100 will be described. In the initial state before the cassette 90 is inserted into the insertion slot 23, the lifting platform 41 is positioned at the uppermost home position within the movable range, and the two guide portions 51 are at the home positions farthest within the movable range. The moving plate 61 is positioned at the rearmost home position within the movable range, the image reading head 80 is positioned at the rightmost home position within the movable range, and the insertion port 23 is blocked by the lid member 28. ing.

  First, the user inserts the cassette 90 into the insertion slot 23 with the back plate 92 of the cassette 90 facing back. Here, since the convex part 25 is provided in the back side of the insertion port 23, when inserting the cassette 90 in the insertion port 23, the cassette 90 can be easily inserted by applying the back surface of the cassette 90 to the convex part 25. It can be aligned with the mouth 23. Furthermore, since the convex portion 25 is also provided on the right side of the insertion port 23, the cassette 90 can be easily aligned with the insertion port 23 by applying the right side surface of the cassette 90 to the convex portion 25. Therefore, the cassette 90 can be inserted into the insertion port 23 quickly and easily.

  When the user inserts the cassette 90 into the insertion slot 23, the roller 31 is pushed backward by the cassette 90, and a reaction force is generated in the leaf spring 30. The reaction force of the leaf spring 30 causes the cassette 90 to move between the roller 31 and the side wall 24. Sandwiched between. When the user releases the cassette 90, the cassette 90 falls due to its own weight, and the roller 31 is driven to rotate about an axis orthogonal to the insertion direction of the cassette 90. When the cassette 90 falls, the cassette 90 is placed on the lid member 28.

  If the cassette 90 is inserted into the insertion slot 23 with the front plate 91 of the cassette 90 facing back, the barcode of the cassette 90 cannot be read by the barcode reader 35, so the lid member 28 remains closed. In that case, the user may simply take the cassette 90 out of the insertion slot 23, return the front and back of the cassette 90, and insert the cassette 90 into the insertion slot 23 again.

  Further, even when the cassette 90 is inserted into the insertion slot 23 with the front and back sides of the cassette 90 correct, if the cassette 90 is on the left side, the barcode of the cassette 90 cannot be read by the barcode reader 35, so the lid member 28 Remains closed. In that case, the user may move the cassette 90 to the right with the cassette 90 inserted into the insertion slot 23. If the cassette 90 is moved to the left and right with the cassette 90 inserted into the insertion slot 23, the rollers 31 that are not in contact with the cassette 90 abut against the left and right end surfaces of the cassette 90, but the generatrix of the outer peripheral surface of the rollers 31 is in the axial direction. Since the diameter is reduced from the center to both ends in the axial direction, the left and right end surfaces of the cassette 90 are not caught by the rollers 31. Therefore, the cassette 90 can be moved to the left and right without removing the cassette 90 from the insertion port 23.

  When the cassette 90 is placed on the lid member 28 and the barcode of the cassette 90 is read by the barcode reader 35, the lid member 28 is rotated downward about the shaft member 29 by the opening / closing motor 33, and the lid member 28. Opens. When the lid member 28 is opened, the cassette 90 falls due to its own weight, and the cassette 90 is placed on the lifting platform 41.

  Next, when the cassette 90 is lowered together with the elevator table 41 by the elevator motor 42 and the cassette 90 is positioned between the guide portions 51, the elevator motor 42 is stopped. At this time, the moving body 73 of the link mechanism 65 in FIG. 12 stands by at a predetermined position. The predetermined position is desirably in a range of 65 mm to 125 mm (distance between the moving body 73 and the back plate 92 of the cassette) with respect to the surface of the cassette 90 that moves up and down. If the cassette is not locked properly due to an operator's mistake such as forgetting to lock it after cleaning, a small cassette of 18 x 24 cm may open and fall over if it is further away. 92 is attracted to the magnet 60. According to this range, all the cassette sizes are loaded abnormally, and the fallen back plate can be returned to the normal position by the next operation, and the apparatus and the cassette are not broken.

  Next, the guide portions 51 approach each other in the left-right direction by the width adjusting motor 52, and the cassette 90 is sandwiched by the guide portions 51. Thereby, the position of the cassette 90 in the left-right direction is accurately adjusted.

  Next, the elevator 41 is lowered by the elevator motor 42, but the cassette 90 is lowered together with the elevator 41 while being guided by the guide portion 51. When the entire cassette 90 enters the housing 101, the lid member 28 is closed by the opening / closing motor 33.

  Next, the ball screw 74 is rotated by the motor 77, and the moving body 73 is raised. As the moving body 73 rises, the link mechanism 65 opens, and the moving plate 61 moves forward in a state substantially parallel to the back surface of the housing 101. When the moving plate 61 moves forward, the moving plate 61 contacts the back plate 92 of the cassette 90, and the back plate 92 adheres to the magnet 60.

  Next, the engagement of the engaging portion of the cassette 90 is released by the lock release mechanism, and the front plate 91 and the back plate 92 can be separated. The lock release mechanism includes a push-up pin that linearly reciprocates the lock portion of the cassette 90, a cam that reciprocates the push-up pin, and a motor. The cam is always grounded to the pin mounting member, and therefore, the locking mechanism of the cassette 90 (not shown) can always be moved at a constant speed. When the locking mechanism of the cassette 90 is subjected to disturbances such as severe impacts and speed changes, an unexpected operation (reverse operation of the lock part) may cause a lock failure or a lock opening / closing operation failure, but such a lock failure can be prevented.

  In addition, when the front plate 91 and the back plate 92 of the cassette 90 are inserted without being integrated due to forgetting to lock or the like, one of them may move (drop) to an unexpected place in the apparatus. It is preferable to optimize the stop origin of the transport section and return all cassettes to their normal positions.

  Next, when the ball screw 74 is rotated reversely by the motor 77, the moving body 73 is lowered, the link mechanism 65 is closed, and the moving plate 61 moves rearward in a state substantially parallel to the back surface of the housing 101. Since the back plate 92 is attached to the magnet 60, the back plate 92 and the photostimulable phosphor sheet 93 move rearward together with the moving plate 61, and the back plate 92 is separated from the front plate 91.

  When the movable plate 61 arrives at the rear home position, the photostimulable phosphor sheet 93 is exposed in a state of facing forward. The image reading head 80 is moved by the linear motor 81 in front of the photostimulable phosphor sheet 93. Move from right to left. While the image reading head 80 is moving, the photostimulable phosphor sheet 93 is scanned along the top and bottom by the laser light of the scanning excitation light irradiation mechanism, and the photostimulated luminescent light emitted from the photostimulable phosphor sheet 93 is emitted. Light is received by the photodetector. When the laser light is incident on the photostimulable phosphor sheet 93, the light emission intensity or the intensity of the photostimulated emission light proportional to the stored radiation energy of the photostimulable phosphor sheet 93 is emitted, along with scanning of the scanning excitation light irradiation mechanism. The stimulated emission light emitted from the photostimulable phosphor sheet 93 is received and photoelectrically converted by the photodetector. As a result, the intensity distribution of the photostimulated luminescent light within the surface of the photostimulable phosphor sheet 93 is acquired as image data, and the radiation image recorded on the photostimulable phosphor sheet becomes image data. The acquired image data is output to an image storage device, an image display device, an image output device, or the like.

  When the image reading head 80 arrives to the left of the photostimulable phosphor sheet 93, the image reading head 80 moves to the right home position with the erasing light irradiation unit turned on. Thereby, the erasing light is incident on the photostimulable phosphor sheet 93, and the radiation energy remaining in the photostimulable phosphor sheet 93 is released by the erasing light.

  When the image reading head 80 arrives at the home position, the moving body 73 is raised by the motor 77 and the link mechanism 65 is opened, and the moving plate 61 moves forward in a state substantially parallel to the back surface of the housing 101. When the moving plate 61 moves forward and the back plate 92 is fitted into the front plate 91, the lock release mechanism engages the engaging portion of the cassette 90. Next, when the ball screw 74 is rotated reversely by the motor 77, the moving plate 61 moves backward, and the magnet 60 is peeled off from the back plate 92.

  Next, the lid member 28 is opened by the opening / closing motor 33. Next, the elevating motor 42 raises the elevating platform 41 to a position below the home position, the width adjusting motor 52 separates the guide portion 51, and the holding of the cassette 90 by the guide portion 51 is released. Then, the lifting / lowering table 41 is moved again to the home position by the lifting / lowering motor 42, and a part of the upper side of the cassette 90 is discharged from the insertion port 23. When the cassette 90 comes out of the insertion slot 23, the user pulls out the cassette 90 from the insertion slot 23.

  As described above, since the insertion port 23 is blocked by the lid member 28, the cassette 90 is inserted in a state where the cassette 90 is inserted into the insertion port 23 and does not fall to the lifting platform 41. It can be moved left and right along the mouth 23. Therefore, the position of the cassette 90 in the left-right direction can be easily and easily adjusted.

  The total height h (FIG. 7) of the casing 101 including the casters Y (FIG. 1) provided at the bottom of the casing 101 of the image reading apparatus 100 of FIG. 7 is preferably in the range of 700 to 710 mm. That is, when the height to the upper surface of the housing is about 1000 mm as in the case of a conventional image reading apparatus, a user having a general height (for example, 170 cm) has the short side of the cassette 90 (the cassette 90 has a maximum size of 14 inches). When trying to insert it into the insertion slot on the top surface of the housing with the vertical direction of 14 inches when it is × 17 inches, it was necessary to lift the cassette 90 against gravity, 7, when the height h to the upper surface 22 is in the range of 700 to 710 mm, assuming that the average height of the user is 170 cm, the cassette 90 does not need to be lifted, and the cassette 90 is attached and detached. Becomes easier.

  Next, the moving body 73 of the link mechanism 65 in FIG. 12 will be further described. The detection sensor detects that the moving body 73 has moved to the reading position and starts the reading operation. However, if the detection sensor does not detect for some reason, it moves for a specified time separately determined by a timer or the like and automatically stops. To do. At this time, the moving body may be stopped by abutting against a stopper or the like (not shown), and the motor may be selected so that the motor will step out with respect to the overload acting on the motor thereafter. Even if such considerations are made, even if the motor continues to rotate in a step-out state even after being stopped by the stopper, the screw part 74 and the nut that moves up and down the screw part may be engaged. It is left. If biting occurs, it will not be possible to release the biting from this state again even if the same startup as during normal startup is performed, and extra time will be required for maintenance in addition to necessary work such as sensor replacement. . On the other hand, in a system that performs precise conveyance, a relatively inexpensive and accurate stepping motor is used. This motor has a characteristic that a relatively large torque is generated at a low speed and a torque is reduced at a high speed. Usually, for the purpose of improving the cycle time, the image reading apparatus 100 is started at a low speed and used in a high speed range. However, when there is a possibility that the image reading apparatus 100 is bitten due to a detection sensor abnormality or the like, In order to control at high speed and release the biting, control is performed so that a larger torque than the biting force is generated. For example, normally, acceleration is performed from the starting torque, but in the event of an error, constant driving is performed at a rotational speed near the maximum starting torque.

  Next, a portion where the moving body 73 of the link mechanism 65 moves to the reading position will be described with reference to FIGS. FIG. 13 is a side view (a) to (f) schematically showing the movement of the moving plate 61, and the length of the moving body corresponding to the position of the moving plate 61 in FIGS. 13 (a) to (f). It is a principal part side view (a ') thru | or (f') which show the relative position of a hole and a horizontal axis shaft rod.

  As shown in FIG. 10, tumblers A and B are disposed on both ends of the upper frame, and tumblers C and D are disposed on both ends of the lower frame. As shown in FIG. 18, each tumbler can swing around a tumbler swinging shaft C1, and a tumbler spring W made of a coil spring is disposed between the tumblers and the spring hook shaft C2. When the moving body 73 is driven by the motor 77 and comes near the reading position, the moving plate 61 starts to push the tumblers A to D as shown in FIG. As shown in FIG. 18, when the tumblers A to D reach the imaginary line m connecting the tumbler swinging shaft C1 and the spring hooking shaft C2, the expansion of the tumbler spring W is maximized (accumulated energy is maximized). If m exceeds m, the moving plate 61 is pressed in a certain direction v by the urging force accumulated in the tumbler spring W, and is brought into contact with the abutting portion T (FIG. 13) for positioning, so that position reproducibility is ensured. Therefore, the position of the photostimulable phosphor sheet 93 adsorbed by the image reading head 80 and the magnet 60 of the moving plate 61 is not required even if there is no need for precise control of the conveyance motor or the like. It becomes possible to maintain the relationship with high accuracy.

  As shown in FIG. 11, the moving body 73 has a long hole 73 b, and a drive transmission path is constituted by a horizontal shaft 73 a penetrating the long hole 73 b in the horizontal direction. Even if the moving body 73 stops at any part of the elongated hole 73b, the tumblers A to D and the abutting part T The stop position of the moving plate 61 is accurate. On the other hand, the tumblers A to D require a large urging force to press the relatively heavy moving plate 61. At the moment when the tumblers A to D are urged by the maximum force accumulated in the tumbler spring W, the moving speed of the moving plate 61 itself is high. As a result, a loud collision noise is generated at the positioning position. In order to prevent this, the image reading apparatus 100 has the following configuration.

  While the moving speed of the moving plate 61 is high by the tumblers A to D, it is prevented from colliding with the abutting portion T (FIG. 13) that defines the positioning position of the moving plate 61 and is moved again by the motor 77 to the positioning position. After coming, it stopped in the range of the long hole 73b with a sufficient margin.

  That is, as shown in FIGS. 13A and 13A, when the moving body 73 descends, the moving plate 61 moves toward the abutting portion T, and the moving plate 61 pushes the tumblers A to D. Thus, as shown in FIGS. 13B and 13B, the tumblers A to D rotate, the horizontal shaft 73a moves down in the elongated hole 73b, and the movable plate 61 moves down the horizontal shaft 73a. However, it does not collide with the abutting portion T. Thereby, it is possible to prevent a large collision sound from being generated at the positioning position of the abutting portion T.

  Subsequently, as shown in FIGS. 13C and 13C, the tumblers A to D are rotated by the urging force of the tumbler springs W (FIGS. 10 and 18) to bring the moving plate 61 into the abutting portion T side. Because it is pressed against, it moves following the movement by the motor control. Then, as shown in FIGS. 13D and 13D, when the position of the moving plate 61 is detected by the detection sensor S1, the motor 77 continues to rotate by a certain amount, and the moving plate 61 is moved to the position shown in FIGS. It comes into contact with the abutting part T as shown in d ′). Even after this contact, the motor 77 continues to rotate and rotates until the horizontal shaft 73a stops halfway in the elongated hole 73b as shown in FIGS. 13 (f) and 13 (f ').

  As described above, after the detection by the detection sensor S1, the horizontal axis 73a is set to overrun by a certain distance within the elongated hole 73b and stopped. The overrun amount is preferably determined in consideration of the distance L between the position of the detection sensor S1 and the abutting portion T. For example, in consideration of the variation in the position of the detection sensor S1 and the variation in the position of the abutting portion T, for example, 7.5 (mm) or more is preferable to 4.5 ± 3.0 (mm). Since the movement from the bottom to the top in the long hole 73b of the horizontal shaft 73a corresponds to about 30 (mm) of the moving amount of the moving plate 61, the above variation can be sufficiently absorbed.

  Next, an image reading head 80 for reading a radiation image will be described with reference to FIGS. FIG. 14 is a top view schematically showing the image reading head 80 and its peripheral portion. 15 is a cross-sectional view of the guide groove of FIG. FIG. 16 is a perspective view of a main part of the guide member of FIG.

  The image reading head 80 is sub-scanned by the linear motor 81, but many electric cables are moved simultaneously for electrical connection such as a drive signal of the image reading head 80 and an image signal after reading. For accurate image reading by the image reading head 80, movement with little unevenness of feed becomes important. However, if this electric cable is entangled or pulled, it causes uneven transport. For this reason, in the image reading apparatus 100, as shown in FIGS. 14 and 15, an electric cable is placed in a guide member 601 such as a cable bear for stabilization, but when space saving layout is performed, the guide member 601 becomes a linear motor. There is a concern that the component 81 may hit other parts while moving together with the image reading head 80. Therefore, as shown in FIG. 15, when the guide member 601 is provided with V-shaped guide grooves 610 with tapered surfaces 611 and 612 on both sides, and when the guide member 601 moves in the guide groove 610, left and right deviation occurs. In addition, the left and right positions are corrected while smoothly sliding on the tapered surfaces 611 and 612 and the normal positions are reached. Therefore, stable sub-scanning movement is possible without causing load fluctuations in the image reading head 80.

  Further, the guide member 601 is disposed on the lower side of the image reading head 80 to reduce the size of the apparatus, and forms the curvature of the guide member 601 in the moving direction. When a plurality of electric cables 602 are stored in the guide member 601 as shown in FIG. 16, the electric cables overlap each other, or the electric cables 602 themselves bounce due to the bending of the electric cables 602, resulting in vibration. The constant speed conveyance of the image reading head 80 is obstructed, which may cause image unevenness. Therefore, in the image reading apparatus 100, as shown in FIG. 16, a plurality of string-like members 603 are arranged between the electric cable 602 and the electric cable 602 arranged inside the guide member 601, and each electric cable 602 is partitioned. I am doing so. Further, a fixing member 604 having a groove 605 is disposed on the lower surface 606 side of the guide member 601 so that the position of the string-like member 603 does not change in the horizontal direction with respect to the traveling direction of the guide member 601. Since the string-like member 603 passes through the groove part 605 between the fixed parts 604, the position change of the string-like member 603 can be prevented and the lower surface 606 does not get in the way when moving the bottom part of the guide groove 610.

  The fixing member 604 may be bonded and fixed to the guide member 601 or may be integrally formed. The number of the groove portions 605 is determined according to the number of the string-like members 603 used. Further, the string-like member 603 and the fixing member 604 may be installed at least at one place, but may be installed at all the guide members 601 or at regular intervals or irregularly with respect to the entire length of the guide members 603. A plurality of them may be installed at intervals, and can be selected in a timely manner according to the usage form of the guide member 603. When the electric cable 602 is partitioned by the string-like member 603 and a plurality of cables 602 are arranged on the guide member 601, the electric cables 602 can be overlapped with each other, and fluctuations in the position of the cables 602 can be suppressed. 602 itself does not play.

  As described above, even when a plurality of electric cables 602 are housed in the guide member 601, the electric cables 602 may overlap with each other, or the electric cables 602 may bend due to bending of the electric cables 602, and vibration may occur. Therefore, the constant speed conveyance of the image reading head 80 is not hindered, the constant speed conveyance of the image reading head 80 can be constantly maintained, and a good diagnostic image can be obtained.

  Further, the image reading head 80 is provided with an erasing light irradiation unit for erasing the stored information of the stimulable phosphor plate, and various lamps are used for erasing light irradiation. Examples include halogen lamps and xenon lamps. In particular, the halogen lamp has a high efficiency and high erasing performance, but has a problem that the lamp itself becomes high temperature. The erasing light irradiation unit that moves integrally with the image reading head 80 can not be cooled by a cooling fan or the like during the reading operation in order to suppress image abnormality due to fan vibration, and the device around the erasing light irradiation unit is used continuously. Due to high temperature. For this reason, in the image reading apparatus 100, in the erasing light irradiation unit that detects the dose of the plate and varies the erasing speed, the cooling fan is operated only when the image reading head 80 is in the retracted (origin) position, and the operating time of the apparatus The cooling time was set to a certain rate or more. Specifically, the ratio of the cooling time out of the total operation time (per cycle time) is set to 40% or more.

  Further, when the lamp cover of the halogen lamp of the erasing light irradiation unit is attached to the image reading unit in the image reading head 80, it is attached with a boss having a good heat insulation, for example, about 8 mm diameter, and the lamp cover and the image reading unit having a high temperature. By changing the frame from surface contact to point contact (by boss shape), heat conduction from the erasing light irradiation unit to the image reading unit can be suppressed, and the cooling effect in the image reading head 80 can be promoted.

  Further, when the cassette 90 is jammed in the image reading apparatus 100, it is necessary to take out the cassette 90 from the apparatus. 7 has a door structure on the front surface 101a, and the lock portion is unlocked by pushing the opening / closing button 101b so that the door can be opened. If the structure around the lock portion is large, the size of the apparatus and inconvenience at the time of taking out the cassette arise, so the lock needs to be downsized. However, since the operability is inconvenient if the operation portion is not large to some extent, the image reading apparatus 100 is provided with an operation door mechanism that achieves both downsizing and operability.

  As shown in FIG. 17, the operation door mechanism has an opening / closing button 101b having a projection sufficient to push the dog 203 around the finger with a sufficient size so as not to protrude from the width dimension of the button 101b. The lock member 201 is arranged. That is, the operation door mechanism includes a dog 203 that changes the pushing operation of the button 101b into a rotating operation, a dog / lock member rotating shaft 204 disposed in the center of the button 101b, and a lock hooked by the rotating operation of the locking member 201. A shaft 201 is provided, and the button 101 b and the lock member 201 are urged in one direction by an urging spring 205.

  According to the operation door mechanism shown in FIG. 17, the button 101b having a sufficient size has a biasing spring 205 at the center and has a good feeling of operation, and the dog 203 is pushed in by the end face 206 of the button 101b. Parts are unnecessary and can be miniaturized. Further, although the center of the dog 203 and the center of the lock member 201 are at the same plane position when viewed from above in the vertical direction, the depth direction L2 in which the lock member 201 is hooked is longer than the distance L1 in which the dog 203 is pressed. The amount of rotation necessary for locking the lock member 201 can be obtained with a smaller stroke of 101b.

  As described above, the best mode for carrying out the present invention has been described, but the present invention is not limited to these, and various modifications are possible within the scope of the technical idea of the present invention. Such modifications are also within the scope of the present invention.
