[First Embodiment]
FIG. 1A shows the appearance of a part of the front surface 7a and the side surface 7c of the rectangular parallelepiped housing 7 to which the radiation of the radiation photographing apparatus (imaging apparatus) 100 having a built-in radiation detection panel 1 is incident. .. FIG. 1B is a perspective view of a part of the back surface 7b and the side surface 7c of the photographing apparatus 100 on the opposite side of FIG. 1A. As shown in FIG. 1 (b), a recessed grip portion 10 is formed on the back surface 7b of the housing 7 of the photographing apparatus 100 of the first embodiment. FIG. 2A shows an internal cross-sectional view of the photographing apparatus 100 in the AA direction in FIG. 1B. FIG. 2B shows an internal cross-sectional view of the photographing apparatus 100 in the BB direction in FIG. 1B. Generally, the photographing apparatus 100 detects the radiation emitted by the radiation source 210 shown in FIG. 11 and transmitted through the subject by the radiation detection panel 1. The image acquired by the photographing apparatus 100 is transferred to the outside, displayed on a monitor or the like, and used for diagnosis or the like. FIG. 1 (b) shows four grips 10 arranged in the peripheral region of the back surface 7b. Each grip portion 10 extends in a first direction orthogonal to one side parallel to each other that defines the outer shape of the back surface 7b. Each grip 10 extends to include a central position between the pair of sides.

The radiation detection panel 1 includes a sensor substrate 1c in which a large number of photoelectric conversion elements (sensors) are arranged on the upper portion, a phosphor layer (scintillator layer) 1a arranged on the sensor substrate 1c, a phosphor protective film 1b, and the like. It is a so-called indirect conversion method composed of. The fluorophore protective film 1b is made of a film having low moisture permeability and protects the fluorophore layer 1a. The radiation detection panel 1 is connected to the flexible circuit board 4. Further, a control board 5 that reads a detection signal from the radiation detection panel 1 and processes the read detection signal is connected to the flexible circuit board 4. As shown in FIG. 2A, the photographing apparatus 100 of the first embodiment includes a rechargeable battery 2 for supplying necessary electric power. Further, the photographing apparatus 100 of the first embodiment also includes a connector 8 for supplying power from the outside by a wired connection and communicating with the outside. The control board 5 and the rechargeable battery 2 are collectively referred to as an electric component. In the first embodiment, the rechargeable battery 2 is arranged between the back surface 7b and the radiation detection panel 1 in the central region surrounded by the peripheral region of the back surface 7b on which the grip portion 10 is formed. The radiation detection panel 1 may be, or is not limited to, a so-called direct conversion type including a conversion element made of a-Se or the like and a conversion element portion in which an electric element such as a TFT is arranged two-dimensionally.

The radiation detection panel 1 is supported by the support base 6 and is included in the housing 7. The housing 7 has a rectangular front surface 7a on which radiation is incident, a rectangular back surface 7b on the opposite side of the front surface 7a across the radiation detection panel 1, and four side surfaces 7c connecting the front surface 7a and the back surface 7b. ing. Further, a cushioning material 3 is arranged between the front surface 7a and the radiation detection panel 1 to protect the radiation detection panel 1.

The photographing apparatus 100 of the first embodiment has the following configuration in order to improve gripability and portability. As shown in FIG. 1 (b), the housing 7 has a recess (grip portion) 10 for grip that is recessed toward the radiation detection panel 1 in a peripheral region along each side of the rectangular back surface 7b. There is. By having the gripping portions 10 along each side of the back surface 7b, it is possible to grip the photographing device 100 in various directions, the photographing device 100 can be easily handled, and the photographing device 100 can be easily taken quickly.

When viewed from the direction opposite to the radiation incident direction, these grip portions 10 have a part of the grip portion 10 or the maximum depth region (bottom surface) D within 60 mm from the side surface 7c of the housing 7. FIG. 3 shows a cross-sectional view of the housing 7 of the photographing apparatus 100 in the CC direction in FIG. 1 (b). FIG. 3 shows an example of the position and shape of the grip portion 10. In the example of FIG. 3, the length of the region (A region) from the side surface 7c of the housing 7 to the start end of the grip portion 10 is 25 to 40 mm, and the length of the region (B region) between the start end and the end of the grip portion 10 is set. It is set to 15 to 30 mm. The dimension of the A region is set to 25 to 40 mm because the gripping forces α and β when the panel-shaped imaging device 100 is held substantially vertically on the ground as shown in FIG. 4A are sufficient for the imaging device 100. This is to get them to join. If the dimension of the A region is too large or too small than 25 to 40 mm, it becomes difficult to grip the photographing apparatus 100. If the B region is too small, there is a problem that it is difficult to insert a finger, and conversely, if the B region is too large, there is a problem that the internal volume of the photographing apparatus 100 is reduced. That is, since the A region and the B region have the above-mentioned dimensions, it is possible to secure a volume for accommodating each component of the photographing apparatus 100 while ensuring portability. Specifically, when the B region becomes larger in the inner direction of the photographing apparatus 100, the space in which the rechargeable battery 2 and the control substrate 5 shown in FIG. 2A are accommodated may be limited. Alternatively, the space for arranging the support base 6 shown in FIG. 2B may be limited.

When holding the photographing device 100 substantially parallel to the ground, such as when inserting the photographing device 100 into the back surface of a subject or the like, it is conceivable to extend and hold the finger as shown in FIG. 4 (b). .. In this case, if the total dimension of the A region and the B region is too large, it becomes difficult to stably support the photographing apparatus 100, and the operability deteriorates. Therefore, the total size of the A region and the B region is set to 60 mm or less. This makes it possible for the photographing device 100 to quickly respond to various types of photographing.

The depth C of the grip portion 10 is set in the housing 7 so that the photographing device 100 can easily rotate in the direction of the palm when the photographing device 100 is held substantially perpendicular to the ground as shown in FIG. 4A. It shall be ½ or more of the distance between the front surface 7a and the back surface 7b. Alternatively, the depth C of the grip portion 10 is set to be equal to or greater than the distance between the back surface 7b of the housing 7 and the center of gravity of the photographing device 100. By providing the depth C of the grip portion 10 in this way, it is easy to generate a moment in which the photographing apparatus 100 rotates in the direction of the palm, and the rotation moment in the direction of escaping from the palm is minimized. As a result, the photographing apparatus 100 is likely to be stable when grasped, and the burden on the user can be reduced. Even if the depth C of the grip portion 10 cannot be deeper than the position of the center of gravity of the imaging device 100, the depth C of the grip portion 10 may be approximately 5 mm or more in order to sufficiently increase the holding force β of the imaging device 100. can.

In the first embodiment, the thickness of the photographing apparatus 100 is 13 to 16 mm so as to conform to the standard dimensions of the general photographing cassette of JISZ4905 (photograph-medical photographing cassette, intensifying screen, film-dimensions and specifications). Therefore, the depth C of the grip portion 10 may be made larger than 6.5 to 8.0 mm. Further, the bottom surface (D region) of the grip portion 10 overlaps with the imaging region for imaging when viewed from the radiation incident direction. Therefore, the upper limit of the depth C of the grip portion 10 is defined to be about 10 to 14 mm so that the grip portion 10 does not penetrate the radiation detection panel 1. Further, in order to make it easier to grip the grip portion 10, the shape of the end portion of the photographing apparatus 100 in which the side surface 7c of the housing 7 intersects the front surface 7a and the back surface 7b is given an R or an inclination as shown in FIG. It can be a shape. Further, as shown in FIG. 3, the grip portion 10 connects the first side wall and the second side wall extending in the first direction orthogonal to one side parallel to each other defining the outer shape of the back surface 7b, and the two side walls. Includes the bottom. The first direction is the longitudinal direction of the grip portion 10 shown in FIG. 1 (b) and is the direction orthogonal to the paper surface of FIG. The angle (first angle) E formed by the side wall far from the center of gravity of the photographing apparatus 100 and the back surface 7b depends on the frictional force, but in order to suppress the decrease in the internal space as much as possible and maintain a sufficient gripping force. In addition, the size is 120 ° or less and 90 ° or more. Further, the angle (second angle) F between the side wall facing the side wall forming the angle E and the back surface 7b is larger than the angle E. Here, the angle F is preferably larger than at least 90 °. Since the inclination angle inside the grip portion 10 becomes gentle, it is possible to easily insert a hand. As a result, when gripping as shown in FIG. 4A, it is possible to obtain an effect that it is easy to insert a hand into the grip portion 10 while suppressing a decrease in the internal space of the photographing apparatus 100 as much as possible.

The surface friction coefficient inside the recess of the grip portion 10 is higher than the surface friction coefficient of the outer surface of the housing 7 excluding the grip portion 10 in order to prevent the photographing device 100 from slipping off from the hand holding the grip portion 10. be able to. This can be achieved by changing the surface texture finish of the housing 7 or by attaching a frictional sheet material or the like to the grip portion 10. The sheet material is made of, for example, a material such as rubber or foamed resin. In order to improve the surface friction coefficient of the grip portion 10, the surface of the grip portion 10 may be provided with irregularities. By increasing the coefficient of friction of the grip portion 10 from the back surface 7b of the housing 7, when the imaging device 100 is inserted into the back surface of the patient or the like, it is slippery and easy to insert, while the image is taken by gripping with the grip portion 10. The device 100 can be stably gripped. As a result, the handleability of the photographing apparatus 100 is improved.

The grip portion 10 may have various shapes as shown in FIGS. 5A to 5C in addition to the shape shown in FIG. In FIG. 5A, the grip portion 10 having a semi-circular cross-sectional shape is used in order to increase the internal volume of the housing 7 of the photographing apparatus 100 as much as possible. In FIG. 5B, the cross-sectional shape of the grip portion 10 is a parallelogram, and in FIG. 5C, the cross-sectional shape of the grip portion 10 is a polygon. When the cross-sectional shape of the grip portion 10 is as shown in FIGS. 5 (b) and 5 (c), the holding force is obtained when the photographing device 100 is held substantially perpendicular to the ground as shown in FIG. 4 (a). The direction of β changes, making it easier to hold the imaging device 100 in the direction of rotation in the palm of the hand, enabling stable gripping. In the first embodiment, no electric component such as a rechargeable battery 2 or a control board 5 is arranged between the grip portion 10 and the radiation detection panel 1.

In the grip portion 10, the back member having the back surface 7b of the housing 7 and the support base 6 for supporting the radiation detection panel 1 are bonded to the housing 7 and the support base 6 by bonding with screws or the like. Can be integrated to improve the rigidity of the photographing apparatus 100. When an electric component or the like is arranged between the grip portion 10 and the radiation detection panel 1, in order to avoid damage to the electric component or the like even if a large load is applied, the electric component or the like is placed between the grip portion 10 and the grip portion 10. Spacers, foaming materials that serve as cushioning materials, and the like can be arranged. Further, a heat radiating material may be arranged between the electric component and the grip portion 10 to efficiently dissipate heat to the outside.

As shown in FIG. 6, when the photographing apparatus 100 is viewed from the direction opposite to the radiation incident direction, the connector 8 for external communication can be arranged on the side surface 7c. In this case, the peripheral region in which the four grip portions 10 are arranged does not include the first peripheral region in which the side surface 7c in which the connector 8 is arranged is included as a boundary line and the side surface 7c in which the connector 8 is arranged as a boundary line. It is divided into two peripheral areas. As shown in FIG. 6, the grip portions 10 formed in the first peripheral region including the side surface 7c in which the connector 8 is arranged as a boundary line are longer than the grip portions 10 formed in the second peripheral region and are longer than each other. It has a different shape. That is, the grip portion 10 formed in the first peripheral region including the side surface 7c on which the connector 8 is arranged may extend to the vicinity of the corner portion of the back surface 7b. In order to charge the photographing device 100, it is conceivable to use an external charging cradle 200 or the like of the photographing device 100, but this is because the handling at that time can be facilitated. The connector 8 can be provided with a holding force by using a magnet or the like, but as shown in FIG. 6, the connector 8 is provided with a force for pulling or rotating the photographing device 100 from the cradle 200 by using the long grip portion 10. It can be easily removed. Further, when the gripping portion 10 is lengthened, the area that can be gripped increases and the photographing device 100 can be easily handled, so that there is an advantage that quick photographing can be easily performed.

In FIG. 6, the connector 8 for external communication is provided on the side surface 7c of the housing 7. However, as shown in FIG. 7, the connector 8 for external communication may be provided inside the grip portion 10. As a result, the connector 8 is arranged at a position where it is difficult for an external force to be directly applied, and the connector 8 can be easily protected. FIG. 7 is a cross-sectional view taken along the line CC in FIG. 1 (b), similar to FIG. As shown in the figure, it is preferable to arrange the connector 8 on the side wall opposite to the side wall of the grip portion 10 that is touched when gripping the photographing apparatus 100.

When gripping the imaging device 100 using the grip portion 10, as shown in FIG. 4, the hand gripping the imaging device 100 touches the grip portion 10 and the periphery of the side portion of the imaging device 100 close to the grip portion 10. It is supposed to cover. Therefore, the switch 11 and the like are not arranged in the area of the photographing apparatus 100 covered by the hand holding the photographing apparatus 100. This is because if the switch 11 or the like is arranged in the area covered by the hand holding the photographing device 100, it is assumed that an erroneous operation will be performed. Also in the first embodiment, as shown in FIG. 6, the switch 11 is installed in a region where there is no grip portion 10 in the vicinity thereof and the switch 11 is not covered by the gripping hand.

The LED or speaker that indicates the status display may be covered with a hand, making it difficult to determine the status. Since the antenna is affected by the radiation performance of the antenna when covered by the hand, it is preferable to arrange the antenna at least half a wavelength away from the area covered by the hand. The speaker also has an influence on the gripping hand and hinders the diffusion of sound. If the connector 8 for wired connection is arranged at a position where the hand covers it, it becomes difficult to grip the photographing device 100 when the connector 8 and the cable are connected. Therefore, the LED and speaker indicating the status display, the antenna for infrared communication and wireless communication, and the connector 8 for wired connection are also arranged in an area not covered by the hand holding the photographing device 100, similarly to the switch 11.

The imaging device 100 of the first embodiment having the above configuration has both improved gripability and miniaturization by providing the gripping portion 10 in the imaging region.

In the second embodiment, even when the photographing device 100 is hidden behind the subject and the grip portion 10 cannot be visually seen, the center of the grip portion 10 is provided so as to be tactilely sensible. In the second embodiment, the portion 10a1 indicating the center is formed in a part of the grip portion 10a. The central portion 10a1 is, for example, a protrusion or depression, as shown in FIG. The central portion 10a1 may have a smoothness different from that of other portions of the grip portion 10a. Further, the portion 10a1 indicating the center may be formed by changing the shape or depth of a part of the cross-sectional shape of the grip portion 10a.

In FIG. 8, four of the five grip portions 10 have their longitudinal directions parallel to the sides defining the outer shape of the back surface 7b, as in the grip portion 10 of the first embodiment. Two of them are grips 10b having no center-indicating portion 10a1 as in the grip 10 of the first embodiment, and the other two are grips 10a having a center-indicating portion 10a1. The remaining one grip portion 10c has the same structure and shape as the grip portion 10 of the first embodiment, but is arranged at the corner portion of the back surface 7b, and the longitudinal direction intersects each of the sides defining the outer shape of the back surface 7b. It is formed like this. The one grip portion 10c is formed so that the direction orthogonal to the longitudinal direction (short direction) of the recess faces the center of gravity or the center of the photographing apparatus 100.

The inner surface on the side of the radiation detection panel 1 of the back member including the back surface 7b of the housing 7 of the second embodiment includes a support surface for supporting the radiation detection panel 1 and is opposite to the radiation detection panel 1 of the back member. A recess 12 for arranging an electric component is formed on the outer surface of the above. As a result, the support base 6 in the first embodiment and a part of the back surface member can be integrated, so that the weight can be easily reduced. Further, since a large number of recesses are formed in the housing 7 by the recesses that serve as the grip portions 10 and the recesses 12 for arranging electrical parts and the like, the bending rigidity of the housing 7 can be increased. Further, as shown in FIG. 9, the back surface member has a structure including a multilayer structure of the core layer 7b2 and the skin layer 7b1 sandwiching the core layer, so that the weight can be easily reduced.
