As described above, in the present embodiment, each readout circuit 17 of the readout IC 16 reads out the electric charge generated in each radiation detection element 7 as a signal value according to the dose of the irradiated radiation.

Then, the signal values output from the amplifier circuit 18 are sequentially transmitted to the A / D converter 20 via the analog multiplexer 21, and are sequentially converted into digital value signal values by the A / D converter 20 to be stored in the storage means 23. It is saved sequentially in. Then, in the present embodiment, signals are transmitted from all the radiation detection elements 7 by performing the above-mentioned readout process while sequentially applying an on-voltage from the gate driver 15b of the scanning drive means 15 to each of the lines L1 to Lx of the scanning line 5.

Further, when power is supplied from the outside through the connector 27, the control means 22 executes charge control for the built-in power supply 24.

Further, as described above, the control means 22 controls the application of the reverse bias voltage from the bias power supply 14 to each radiation detection element 7, and controls the operation of the scanning drive means 15, the readout circuit 17, and the like. The signal value from the radiation detection element 7 is read out, the read signal value is stored in the storage means 23, or the stored signal value is transferred to the outside via the communication unit 30. Etc. are controlled.

[Portable radiation imaging device storage mechanism]
Next, the portable radiographic imaging apparatus storage mechanism 40 will be described in detail with reference to FIGS. 1 and 4 to 9. The portable radiation imaging device storage mechanism 40 is provided at the rear of the vehicle body 101 of the round-trip vehicle 100, and inserts and holds the unused portable radiation imaging device 1 in the portable radiation imaging device 1. On the other hand, it can be charged.

FIG. 4 is a schematic configuration diagram of a portable radiation imaging apparatus storage mechanism 40. The horizontal direction and the vertical direction on the paper surface of FIG. 4 are the horizontal direction and the vertical direction of the portable radiation imaging device storage mechanism 40, and the direction perpendicular to the paper surface of FIG. 4 is the portable radiation imaging device storage mechanism 40. Each part will be explained as the front-back direction in. In addition, the front side of the paper is referred to as "rear", the depth side of the paper is referred to as "front", the left hand side is referred to as "left", and the right hand side is referred to as "right".

A slot 102 (see FIG. 1) that opens upward is formed in the rear portion of the vehicle body 101, and a portable radiographic imaging device storage mechanism 40 is provided inside the slot 102. By inserting the portable radiographic imaging apparatus 1 into the slot 102 from above, a loading operation is performed on the portable radiological imaging apparatus accommodating mechanism 40.
Then, as shown in FIG. 4, the portable radiation imaging device storage mechanism 40 has a power supply connector 41 that supplies power to the portable radiation image pickup device 1 and left and right that guide the portable radiation image pickup device 1 to the power supply connector 41. A cover mechanism 50 having a pair of guides 42 and a protective cover 51 for shielding the power supply connector 41 from the outside, and a shock absorber 60 for alleviating an impact generated when the portable radiographic imaging device 1 is loaded are provided. There is.

The left and right guides 42 are formed with guide grooves 421 (see FIG. 5) for sliding the left end portion and the right end portion of the housing 4 of the portable radiographic imaging apparatus 1 along the vertical direction. The left and right guides 42 are arranged so that the guide grooves 421 face each other, and when the portable radiographic imaging device 1 is inserted into the slot 102, the guide grooves 421 of the guides 42 take a portable radiographic image. The positions of the device 1 in the left-right direction and the front-back direction are defined and guided downward.

A pair of left and right linear acting dampers 61 constituting the shock absorber 60 are individually arranged at the left and right ends of the inner bottom portion 103 of the slot 102.
The damper 61 has a piston structure, and constitutes a viscous damper in which a viscous fluid enclosed in a cylinder generates viscous resistance to provide cushioning.
As the damper 61, a viscous damper that imparts frictional resistance to the piston may be adopted, or an elastic damper that cushions by compressing the gas sealed in the cylinder or the coil spring may be adopted. .. Further, the pair of left and right viscous dampers and the pair of left and right elastic dampers may be used in combination.
Further, the number of dampers is not limited to one or two, and more dampers may be provided.

Each of the dampers 61 is provided in the inner bottom portion 103 of the slot 102 with the piston rod protruding upward, and a damper cap 62 having a flat upper end surface is attached to the upper end portion of the piston rod. The upper end surface of the damper cap 62 is a contact surface that abuts on the bottom surface of the portable radiographic imaging apparatus 1.
Further, each damper 61 is arranged so as to abut on the portable radiographic image capturing apparatus 1 to be loaded so as to be in contact with the position avoiding the power switch 31, the changeover switch 32, the indicator 33 or the connector 27 on the bottom surface.
Then, when the portable radiographic imaging device 1 is loaded in the slot 102, the bottom surface thereof abuts on the contact surface of the damper caps 62 of the left and right dampers 61, and the piston rod is pushed downward to generate viscous resistance. , Mitigates the impact of collision during loading.
At this time, by providing an elastic material such as a cushion on the portion of the damper cap 62 including at least the contact surface, the impact due to the collision at the time of loading can be more effectively mitigated.

Further, in the shock absorber mechanism 60, since the pair of dampers 61 abut on the left and right ends of the bottom surface of the portable radiographic imaging apparatus 1, the impact is stably reduced while reducing the left-right tilt of the portable radiographic imaging apparatus 1. It is possible to mitigate.
In this case, by arranging the left and right dampers 61 so as to be in contact with each other at positions equidistant from the center of gravity of the portable radiographic imaging apparatus 1, the left and right inclinations are reduced more effectively and the left and right inclinations are stably reduced. It is possible to mitigate the impact.

FIG. 5 is a perspective view of the periphery of the power supply connector 41 when the protective cover 51 of the cover mechanism 50 is closed, FIG. 6 is the same perspective view when the protective cover 51 is open, and FIG. 7 is a left-right view of the cover mechanism 50. A side view, FIG. 8 is a perspective view of the cover mechanism 50 in a state where the protective cover 51 is closed, and FIG. 9 is a perspective view of the cover mechanism 50 in a state where the protective cover 51 is open.

As shown in FIGS. 5 and 6, the power supply connector 41 has a connection port facing upward inside a rectangular opening 104 formed in the inner bottom portion 103 of the slot 102 between the pair of dampers 61. Equipped with. The power supply connector 41 and the connector 27 of the portable radiographic imaging apparatus 1 are structurally in a male-type and female-type relationship, and can be connected to each other.
Further, the power supply connector 41 is connected to a power supply circuit that takes in a built-in power supply or an external power supply (not shown) of the round-trip vehicle 100, and when the connector 27 of the portable radiographic imaging apparatus 1 is connected, the portable radiological imaging apparatus 1 is connected. Power can be supplied to one side to charge the built-in power supply 24 of the portable radiographic imaging apparatus 1.

Further, the power feeding connector 41 is provided at a position on the inner bottom portion 103 of the slot 102 that coincides with the connector 27 of the portable radiographic imaging apparatus 1 loaded by the left and right guides 42 in a plan view. Therefore, when the bottom surface of the portable radiographic imaging apparatus 1 reaches the inner bottom portion 103 of the slot 102, the connector 27 can be connected to the power feeding connector 41.

As shown in FIGS. 5 to 9, the cover mechanism 50 includes a pair of protective covers 51 that close the opening 104, a support arm 52 that supports the protective cover 51, and a rotation shaft 53 of each support arm 52. It is provided with a pair of driven gears 54 provided in the above, a rack tooth 55 formed on the damper cap 62 of the damper 61 described above, and a pinion gear 56 that meshes with the rack tooth 55.

The protective cover 51 is a rectangular flat plate having a size that divides the opening 104 into two front and rear, and the opening 104 can be closed by arranging a pair of protective covers 51 in the front and rear.
Support arms 52 extending downward with the protective cover 51 closed are integrally provided at both left and right ends of the protective cover 51. The support arm 52 of the front protective cover 51 is provided near the rear side of the protective cover 51, and the support arm 52 of the rear protective cover 51 is provided near the front side of the protective cover 51.
Each support arm 52 is rotatably supported on the inner wall of the opening 104 by a rotation shaft 53 along the left-right direction at its lower end. Therefore, due to the rotation of the support arm 52, the protective cover 51 moves downward from the closed state between the feeding connector 41 and the inner wall of the opening 104 to open the opening 104 and to open the feeding connector 41. It can be exposed upwards.

The rotation shaft 53 is fixed to the support arm 52, and the rotation shaft 53 is fixedly equipped with a driven gear 54 centered on the rotation shaft 53. Therefore, the protective cover 51, the support arm 52, the rotating shaft 53, and the driven gear 54 integrally rotate.
The driven gear 54 on the support arm 52 side of the rear protective cover 51 meshes with the pinion gear 56 provided on the lower side thereof, and the driven gear 54 on the support arm 52 side of the front protective cover 51 meshes with the pinion gear 56 provided below the pinion gear 56. It meshes with the driven gear 54 on the support arm 52 side of the protective cover 51 on the side.

On the other hand, the pinion gear 56 is rotatably supported on the inner wall of the opening 104 around a rotation axis along the left-right direction.
The pinion gear 56 also meshes with the rack teeth 55 formed on the damper cap 62 along the vertical direction.
As a result, the loading operation of the portable radiographic imaging apparatus 1 is performed, and when the bottom surface thereof abuts on the damper cap 62 and is pushed downward, the descending rack teeth 55 reverse the pinion gear 56 as shown in FIG. Rotate it clockwise, rotate the driven gear 54 on the rear protective cover 51 side clockwise, and rotate the driven gear 54 on the front protective cover 51 side counterclockwise.
The rack teeth 55 may be provided on another member that moves up and down with the loading of the portable radiographic imaging apparatus 1.
Therefore, the pair of protective covers 51 are opened in conjunction with the loading operation of the portable radiographic imaging apparatus 1, and the power feeding connector 41 can be coupled to the connector 27 of the portable radiographic imaging apparatus 1.
Therefore, when the portable radiographic imaging apparatus 1 is loaded, it can be stored in the slot 102 and the built-in power supply 24 of the portable radiographic imaging apparatus 1 can be charged.

[Technical effect of the first embodiment]
The portable radiographic imaging device storage mechanism 40 in the round-trip vehicle 100 is protected so that the cover mechanism 50 shields the power supply connector 41 from the outside in conjunction with the loading operation of the portable radiographic imaging device 1 according to the guide 42. It has a function of opening the cover 51.
Therefore, when the portable radiographic imaging apparatus 1 is not loaded, the protective cover 51 is closed and the power supply connector 41 can be maintained in a state of being shielded from the outside, so that dust and moisture can enter the power supply connector 41. It is possible to suppress and maintain high dust-proof and drip-proof properties.
Further, since the protective cover 51 is opened in conjunction with the loading operation of the portable radiographic imaging device 1, the protective cover 51 can be opened by using the weight of the portable radiographic imaging device 1, and the protective cover 51 can be opened. It is possible to eliminate the need for a drive source for opening.

Further, since the portable radiographic image pickup device storage mechanism 40 includes the shock absorber mechanism 60, it is possible to alleviate the impact at the time of loading based on the weight of the portable radiographic image pickup device 1, and the damage at the time of loading may occur. The portable radiographic imaging apparatus 1 can be effectively protected from deformation, scratches, and the like.
In particular, since the shock absorber 60 includes a pair of linear motion dampers 61, the damper 61 can be made portable by matching the loading direction of the portable radiographic imaging apparatus 1 with the linear motion direction of the damper 61. The impact can be effectively mitigated by bringing it into contact with the radiation imaging apparatus 1.

Here, FIG. 10 shows a conventional buffer mechanism 160. This conventional shock absorbing mechanism is configured to include a sliding contact body 161 that is individually slid on the left and right side surfaces of the portable radiographic imaging apparatus 1 in the guide grooves 421 of the left and right guides 42. The sliding contact body 161 is undulating and rotatable, and a spring pressure (not shown) is applied to the portable radiographic imaging apparatus 1 side so as to be undulating.
As a result, when the portable radiographic imaging apparatus 1 is loaded, the rotating end portion of the sliding contact body 161 is slidably contacted with the left and right side surfaces thereof with a constant pressing force, and the impact is alleviated by the sliding friction.
In the shock absorber 160 using such a sliding contact body 161, the left and right corners of the bottom of the portable radiographic imaging apparatus 1 always collide with the sliding contact body, so that cumulative damage is accumulated in the corners. , There is a risk of destruction due to repeated loading operations.
In addition, it is unavoidable that scratches and damages due to sliding are generated on the left and right side surfaces of the portable radiographic imaging apparatus 1. In this case, if the surface of the housing 4 of the portable radiographic imaging apparatus 1 is painted or coated, it causes peeling.
Further, as shown in FIG. 11, when the portable radiographic imaging apparatus 1 is loaded in the wrong direction, the power switch 31, the changeover switch 32, the indicator 33, or the connector 27 provided on the bottom surface slides with the sliding contact body 161. It can move and cause these damages and malfunctions.
On the other hand, as described above, the shock absorber 60 of the portable radiation imaging apparatus storage mechanism 40 uses the linear motion damper 61, so that the sliding problem does not occur and the sliding contact body is not generated. Since it is not a structure that makes line contact like 161 it is possible to effectively alleviate the impact when the portable radiographic imaging apparatus 1 is loaded.
In addition, since the sliding contact bodies are not provided on both the left and right sides, the device can be miniaturized in the left-right direction, the round-trip car 100 can also be miniaturized, and it can be used between narrow beds in the doctor's office. Will be.

Further, in the portable radiation imaging device storage mechanism 40, since the power feeding connector 41 is arranged between the two dampers 61, the occurrence of the tilted state of the portable radiation imaging device 1 is reduced and the portable radiation imaging device 1 can be stably moved. It is possible to connect the connector 27 of the portable radiation imaging apparatus 1 and the power feeding connector 41.

Further, the cover mechanism 50 of the portable radiation imaging apparatus storage mechanism 40 is configured to open the protective cover 51 in conjunction with the shock absorber mechanism 60.
Therefore, the energy required to open the protective cover 51 can also be used for impact mitigation during loading of the portable radiographic imaging apparatus 1, and efficient impact mitigation can be realized.

[Appropriate contact area of the damper of the shock absorber with respect to the portable radiological imaging device]
Here, an appropriate contact area of the damper 61 of the shock absorber 60 with respect to the portable radiographic imaging apparatus 1 will be described with reference to an example of specific numerical values.
Damage to the housing 4 of the portable radiographic imaging apparatus 1 occurs when the maximum allowable stress is exceeded.
The stress generated in an object to which an external load is applied is shown in the following equation (1).
σ ＝ P / A… (1)
(Σ: stress, P: compressive force, A: cross section)

When the above equation (1) is applied to the housing 4 of the portable radiographic imaging device 1, the stress σ in the equation (1) is the stress applied to the contact point between the housing 4 and the damper 61, and the compressive force is the loading force. The cross-sectional area is considered to be the contact area S of the damper 61.
Therefore, when the following equation (2) is satisfied, the housing 4 is damaged.
σm <P / S… (2)
(Σm: maximum allowable compressive stress, P: compressive force, S: contact area of damper)

The contact area of the damper 61 capable of protecting the housing 4 from damage according to the condition of the above equation (2) was derived as follows.
First, the compressive force P is derived. The compressive force P in Eq. (2) above indicates a static load. However, since the collision that occurs between the housing 4 of the portable radiographic imaging apparatus 1 and the damper 61 is a dynamic load, it is necessary to replace it with an impact load F. The impact load F is derived by the following equation (3).
F = (mv) / t… (3)
(F: impact load, m: mass of portable radiographic imaging device, v: collision speed, t: time required for deceleration)

The collision speed v is assumed to be the speed at which the inner bottom portion 103 of the slot 102 is reached when the guide 42 is freely dropped from the upper end. In that case, the collision velocity v is derived by the following equation (4).
v = √ (2gh)… (4)
(G: Gravitational acceleration, h: Guide height [Descent distance when loading portable radiographic imaging device])

The condition of the contact area S of the damper for avoiding the damage of the portable radiographic imaging apparatus 1 determined based on the above equations (1) to (3) is as shown in the following equation (5).
S ≧ F / σm
≧ (mv) / (t ・ σm)
≧ (√ (2gh) ・ m) / (σm ・ t)… (5)

Substitute an example of a concrete numerical value in the above equation (5).
For example, the mass m of the portable radiographic imaging apparatus 1 is 4.8 [kg] in a 460 [mm] square size.
Then, the height h of the guide 42 is set to 460 [mm] that can support the entire portable radiographic imaging apparatus 1.
From the equation (4), the collision velocity v is v = √ (2 × 9.806 × 0.460) = 3.00 [m / sec].
The time required for deceleration by the shock absorber 60 is 0.01 [sec].
In that case, the impact load F is F = 4.8 × 3.00 ÷ 0.01 = 1440 [N] from the equation (3).
The housing 4 of the portable radiographic imaging apparatus 1 is generally composed of PC (polycarbonate), CF (carbon fiber), RP (reinforced plastic), Al (aluminum alloy), and Mg (magnesium alloy). However, the most vulnerable to impact among these materials is PC, which has a maximum allowable stress of about 66 [MPa].
Assuming a PC as the forming material of the housing 4, the minimum value of the contact area S of the damper is S ≧ 1440 / (66 × 10 ⁶ ) [m ² ] according to the equation (5). That is, S ≧ 21.82 [mm ² ].
For example, if the contact surface of the damper 61 is a circle with a diameter of 4 [mm] and is provided at two locations on the left and right, S = 2 × 2 × 3.14 × 2 = 25.12 [mm ² ], and the condition of Eq. (5) Can be met.

The points will be explained.

As described above, it is desirable to increase the contact area of the shock absorber mechanism, but increasing the size of the damper itself causes an increase in the size of the device.
Therefore, in this portable radiation imaging device storage mechanism 40A, a movable bottom plate 63A supported in a suspended state is provided on a pair of dampers 61, and the portable radiation imaging device 1 is contacted via the movable bottom plate 63A.

Regarding the portable radiation imaging device storage mechanism 40B of the third embodiment, the same components as those of the portable radiation imaging device storage mechanisms 40 and 40A described above are designated by the same reference numerals, and duplicate explanations are omitted. Explain the differences.
FIG. 13 is a rear view of the periphery of the power supply connector 41 in a state where the protective cover 51B of the cover mechanism 50B of the portable radiation imaging apparatus storage mechanism 40B is closed, and FIG. 14 is a rear view in a state where the protective cover 51B is opened. 15 is a side view of the cover mechanism 50B when the protective cover 51B is closed, and FIG. 16 is a side view of the cover mechanism 50B when the protective cover 51B is open.

The portable radiographic imaging apparatus storage mechanism 40B is characterized by including a movable support mechanism 65B for advancing the power supply connector 41 to the portable radiographic imaging apparatus side in conjunction with the loading operation of the portable radiographic imaging apparatus 1. It is one of the.
The movable support mechanism 65B is interlocked with the damper 61 of the buffer mechanism 60 that moves forward and backward by the loading operation of the portable radiographic imaging device 1.

The movable support mechanism 65B includes a rack tooth 66B along the vertical direction provided on the damper cap 62 of the damper 61, a pinion gear 67B that meshes with the rack tooth 66B, and a rack tooth 68B fixedly mounted on the side surface of the power feeding connector 41. It has a support mechanism (not shown) such as a slide guide that slidably supports the power supply connector 41 in the vertical direction.
The pinion gear 67B is rotatably supported on the inner wall of the opening 104 around a rotation axis along the front-rear direction.
Further, the rack teeth 68B of the power feeding connector 41 are formed along the vertical direction, and mesh with the pinion gear 67B on the opposite side of the rack teeth 66B of the damper cap 62.

As a result, as shown in FIG. 14, when the portable radiographic imaging device 1 is loaded and the damper cap 62 of the damper 61 is pushed downward, the rack teeth 66B are lowered and the pinion gear 67B is rotated in the clockwise direction shown in the figure. do. As a result, the rack teeth 68B on the power feeding connector 41 side are provided with upward movement, and the feeding connector 41 also protrudes upward from the opening 104 and is connected to the connector 27 of the portable radiographic imaging apparatus 1.

Further, in the cover mechanism 50B of the portable radiation imaging apparatus storage mechanism 40B, the protective cover 51B is opened by utilizing the vertical movement of the power feeding connector 41. That is, the protective cover 51B is opened in conjunction with the shock absorber 60 via the power supply connector 41.

As shown in FIG. 15, the cover mechanism 50B includes a pair of front and rear protective covers 51B capable of closing the opening 104, and a link member 52B for connecting each protective cover 51B to the power feeding connector 41.
The pair of protective covers 51B are supported so as to be slidable horizontally and in the front-rear direction under the opening 104, close the openings 104 in a state of being lined up in the front-rear direction without a gap, and move apart from each other in the front-rear direction. By doing so, the opening 104 can be opened.

One end of each link member 52B is rotatably connected to the protective cover 51B around the axis in the left-right direction, and the other end rotates around the axis along the left-right direction on the side surface of the power supply connector 41. It is connected as possible.
The link member 52B connected to the front protective cover 51B is connected to the power supply connector 41 in a state of being inclined diagonally upward in the front, and the link member 52B connected to the protective cover 51B on the rear side is diagonally upward in the rear. It is connected to the power supply connector 41 in an inclined state.

Therefore, as shown in FIG. 16, when the power feeding connector 41 moves upward, the link member 52B connected to the front protective cover 51B tilts further forward and moves the front protective cover 51B further forward. Similarly, the link member 52B connected to the rear protective cover 51B is tilted more rearward to move the rear protective cover 51B further rearward.
As a result, the opening 104 is opened as the power supply connector 41 rises, and the power supply connector 41 can be exposed or protruded upward from the opening 104.

The portable radiation imaging device storage mechanism 40B has the same technical effects as the portable radiation imaging device storage mechanism 40, and by providing the movable support mechanism 65B, when the portable radiation imaging device 1 is loaded. The power feeding connector 41 can be advanced and moved to the portable radiographic imaging apparatus 1 side. Therefore, the power supply connector 41 can be effectively connected to the connector 27 even when the connector 27 of the portable radiographic imaging apparatus 1 does not protrude downward or is recessed from the bottom surface.
The arrangement direction and opening direction of the protective cover 51B are not limited to the front-rear direction but may be the left-right direction.
Further, the cover mechanism 50 described above may be provided instead of the cover mechanism 50B.

[Fourth Embodiment]
A fourth embodiment of the present invention will be described with reference to FIGS. 17 to 20. This embodiment shows another example of a portable radiographic imaging apparatus storage mechanism. Regarding the portable radiation imaging device storage mechanism 40C of the fourth embodiment, the same components as those of the portable radiation imaging device storage mechanisms 40 to 40B described above are designated by the same reference numerals, and duplicate explanations are omitted. Explain the differences.
17 is a schematic configuration diagram of the portable radiation imaging device storage mechanism 40C, FIG. 18 is a perspective view of the shock absorber mechanism 60C, FIG. 19 is a side view of the cover mechanism 50C with the flap plate 61C closed, and FIG. 20 is a flap plate. It is the same side view with 61C opened.

The portable radiographic imaging apparatus storage mechanism 40C has a structure in which the shock absorber 60C has a plurality of linearly driven dampers 61 and a rotary damper 66C, and the cover mechanism 50C is interlocked with the shock absorber 60C. It is characterized by having.

As shown in FIG. 18, the shock absorber mechanism 60C includes a plate-shaped flap plate 61C arranged in the middle of the guide path of the portable radiographic imaging apparatus 1 using a pair of guides 42, and a rotation shaft 62C of the flap plate 61C. The main gear 63C fixedly mounted on the rotary shaft 62C, the driven gear 64C that meshes with the main gear 63C, the rotary shaft 65C of the driven gear 64C, and the rotary damper mounted on the rotary shaft 65C. It is provided with 66C and a leaf spring 67C that applies a returning force to the flap plate 61C that has rotated downward.

The flap plate 61C has a long flat plate shape, and is horizontally arranged so as to block the guide path of the portable radiographic imaging apparatus 1 by the pair of guides 42 when the portable radiographic imaging apparatus 1 is not loaded. There is.
A rotation shaft 62C along the left-right direction is fixedly mounted on one end of the flap plate 61C in the front-rear direction (here, the rear end is exemplified), and one end thereof (here, the right end is exemplified) is fixedly equipped. The main gear 63C is fixedly equipped. Further, both ends of the rotating shaft 62C are rotatably supported by the left and right guides 42.
As a result, the flap plate 61C, the rotating shaft 62C, and the main gear 63C integrally rotate.

The flap plate 61C is restricted in rotation range by a stopper (not shown) so that the flap plate 61C rotates in a range of approximately 90 ° from a state in which the flat plate surface is horizontal to a state in which the rotation end thereof faces downward. ..
Here, in the following description, a state in which the flat plate surface of the flap plate 61C faces horizontally and blocks the guide path of the portable radiographic imaging apparatus 1 is referred to as a “closed state”, and the rotating end thereof is downward. The state of being evacuated from the guide path of the portable radiographic image capturing device 1 is referred to as an "open state".

The driven gear 64C is fixedly mounted on the rotating shaft 65C along the left-right direction, and the torque from the main driving gear 63C is transmitted to the rotating shaft 65C. Therefore, the flap plate 61C, the rotary shaft 62C, the main gear 63C, the driven gear 64C, and the rotary shaft 65C interlock with each other to perform a rotary operation.

The rotary damper 66C is a viscous damper with a built-in wineway clutch, and torque resistance is applied only to the rotation direction of the rotation shaft 65C when the flap plate 61C rotates from the closed state to the open state. Give.
Further, the rotation shaft 65C is connected to the leaf spring 67C, and when the flap plate 61C rotates from the closed state to the open state, it is elastic so as to return to the closed state with respect to the rotation shaft 65C. Gives recovery power. As described above, since the damper 66C is provided with a wineway clutch, torque resistance is not applied to the rotation shaft 65C when the leaf spring 67C rotates in the return direction, and the flap plate 61C is quickly closed. It can be returned to the state.
The damper 66C may be composed of an elastic damper that generates an elastic force in the same direction as the leaf spring 67C. In that case, the leaf spring 67C can be eliminated.

As shown in FIG. 19, the cover mechanism 50C includes a pair of protective covers 51, a support arm 52, a rotating shaft 53, a driven gear 54, and a pinion gear 56, similarly to the cover mechanism 50 described above. In addition to these, the cover mechanism 50C includes a first transmission gear 57C fixedly mounted on the rotation shaft 62C of the flap plate 61C, a rack member 58C having rack teeth that mesh with the transmission gear 57C, and a pinion. A second transmission gear 59C that meshes with the gear 56 is provided.

The rack member 58C is supported by a guide 42 so that the rack teeth can move up and down in a state of being able to move up and down along the vertical direction. Further, the rack teeth of the rack member 58C mesh with the transmission gear 57C at the upper part and with the pinion gear 56 at the lower part.

When the portable radiographic imaging device 1 is inserted into the slot 102, the portable radiographic imaging device storage mechanism 40C having the above configuration is guided downward by the guide 42, and the bottom surface thereof hits the flap plate 61C in a closed state. Contact. As a result, the flap plate 61C rotates toward the position where it is in the open state. At this time, the rotary damper 66C generates torque resistance and acts on the flap plate 61C, so that the momentum of the downward movement of the portable radiographic imaging apparatus 1 is reduced and the impact when reaching the inner bottom portion 103 is alleviated. Will be done.

On the other hand, when the flap plate 61C rotates from the closed state to the open state, the transmission gear 57C interlocks and rotates counterclockwise in FIGS. 19 and 20, and the rack member 58C moves upward.
Further, the pinion gear 56 rotates counterclockwise, and as shown in FIG. 20, each driven gear 54 rotates in the opposite direction to each other, and the pair of protective covers 51 are directed to both sides of the power feeding connector 41. The opening 104 is opened.

The power supply connector 41 of the portable radiation imaging device storage mechanism 40C is provided with rack teeth that mesh with the second transmission gear 59C on one side thereof, like the portable radiation imaging device storage mechanism 40B described above. ing. Since the second transmission gear 59C meshes with the pinion gear 56, when the pinion gear 56 rotates counterclockwise when the protective cover 51 is opened, the second transmission gear 59C rotates clockwise. The power supply connector 41 can be raised via the rack teeth.
As a result, the power feeding connector 41 projects upward from the opening 104 and is connected to the connector 27 of the portable radiographic imaging apparatus 1 that has reached the inner bottom portion 103.

As described above, even in the case of the portable radiation imaging device storage mechanism 40C provided with the shock absorber 60C having the rotary damper 66C, the same technical effect as the above-mentioned portable radiation imaging device storage mechanism 40, 40B can be obtained. It is possible.
Further, after the portable radiographic imaging apparatus 1 is inserted, the flap plate 61C is maintained in a state of being pressed against the portable radiographic imaging apparatus 1 by the action of the leaf spring 67C, so that the portable radiographic imaging apparatus during storage is maintained. It is possible to reduce the occurrence of the shaking of 1.

The rotary damper 66C may be slightly larger than the torque applied to the rotary shaft 65C with the portable radiographic image capturing device 1 mounted on the flap plate 61C.
As a result, when the portable radiographic imaging device 1 is inserted up to the flap plate 61C, the flap plate 61C maintains the closed state, and further, it is possible to do not artificially apply a force to push the portable radiographic imaging device 1 into the portable radiographic imaging device 1. The connector 27 of the portable radiographic imaging apparatus 1 can be configured not to be connected to the power feeding connector 41.
In the case of such a configuration, for example, in order to avoid overcharging of the portable radiographic image capturing apparatus 1, it is possible to use the portable radiographic imaging apparatus 1 properly for storage without charging and for storing while charging.

Further, the cushioning mechanism 60C includes both a rotary damper 66C and a linearly driven damper 61, but if a sufficient cushioning effect can be obtained only by the rotary damper 66C, the linearly driven damper 66C is used. The damper 61 may be omitted, and only the rotary damper 66C may be provided.
Further, although the rotary damper 66C is provided on only one side of the flap plate 61C, it may be provided on both ends.

It abuts on the flap plate 61C in the state. As a result, the flap plate 61C rotates toward the open position while receiving the torque resistance of the rotary damper 66C. As a result, the momentum of the downward movement of the portable radiographic imaging apparatus 1 is reduced, and the impact when reaching the power feeding connector 41 is alleviated.
Then, the portable radiographic imaging apparatus 1 descends at a low speed, and its connector 27 is connected to the power feeding connector 41.
