By the way, in order to ensure complete diagnosis in the medical field, the portable ultrasonic diagnostic imaging apparatus is provided with noise countermeasures such as a metal case or a metal plate inside the case. This increased the weight of the device.
In addition, the display panel of the ultrasonic diagnostic imaging apparatus requires a special liquid crystal panel that can clearly display the density of low-brightness images, and this liquid crystal panel is thicker than that for normal use. Large, heavy ones were used.
In recent years, it has been proposed to provide a touch sensor on a display panel and perform various operations directly from the display panel.

When the second housing is opened, the retaining claw can be released by performing a release operation. However, if the weight of the second housing containing the display panel is large, it can be released with one hand. While maintaining the locking claw in the released state, it is necessary to start up the second casing with the other hand, and there is a problem that the operation becomes complicated.

The horizontal arm 63 can rotate about the vertical axis V together with the rotation shaft 64. In addition, when the horizontal arm 63 is in a state along the left-right direction, the display panel 16 of the lid 14 is in a state of facing frontward or rearward.
Disc-shaped flanges 63 a extending upward are integrally formed at both ends of the horizontal arm 63. A cylindrical torque limiter 62 that is aligned with the outer surface of the flange 63a is fixed to the outer surface of the flange 63a.

The attachment plate 61 has an arm 61b attached to the torque limiter 62, and a flat plate-like attachment portion 61a integrally formed at the tip of the arm 61b. The attachment portion 61 a has a plurality of screw holes and is configured to be screwed to the lid body 14.
In this embodiment, since it is configured as described above, the lid body 14 can be supported in its posture by a torque limiter provided in each part after being rotated about the vertical axis V and the horizontal axis H. It is like that.

  In the present embodiment, as described above, the biaxial hinge is applied as the hinge 60. However, a uniaxial hinge that can rotate only the horizontal axis H may be used.

As a result, the ultrasonic probe P transmits ultrasonic waves (transmitted ultrasonic waves) to a subject such as a living body (not shown), and also reflects reflected waves (reflected ultrasonic waves: echoes) reflected by the subject. ) Can be received. That is, the ultrasonic diagnostic imaging apparatus 10 transmits an ultrasonic signal to the subject by transmitting a drive signal of an electrical signal to the ultrasonic probe P, and transmits the ultrasonic wave to the subject. Based on the received signal, which is an electrical signal generated by the ultrasound probe P in response to the reflected ultrasound wave from the subject received by the probe P, the internal state in the subject is imaged as an ultrasound image. can do.

[Operation Area]
An operation region 18 in which one or more operation members such as a trackball, a dial, and a button that can be operated by a user are arranged on the front side of the upper surface 12a of the apparatus main body 12 with respect to the hinge 60 is formed. In addition, a substantially rectangular gripping hole 20 is formed in the approximate center of the operation area 18 so that the user's hand can be inserted. That is, the operation region 18 is configured such that an operation member is disposed around the gripping hole 20. The user can grip the grip portion 22 formed in front of the grip hole 20 with the hand inserted through the grip hole 20. With this configuration, the ultrasonic diagnostic imaging apparatus 10 can be easily carried with one hand.

[Fixing mechanism]
3 is a perspective view of the ultrasonic diagnostic imaging apparatus 10 when the lid 14 is tilted, FIG. 4 is a perspective view of the rear end portion of the apparatus main body 12, and FIG. 5 is taken along the line V-V in FIG. It is sectional drawing.
As shown in FIGS. 3 to 5, a fixing mechanism 70 is provided in the vicinity of the rear end of the apparatus main body 12 to fix the lid 14 in a tilted state folded to the apparatus main body 12 side.
The fixing mechanism 70 locks the locked surface 142 and the locked surface 142 as a locked portion formed inside the recess 141 formed on the end surface of the rotating end portion of the lid body 14. A hook member 71 having a locking claw 711 and a spring 72 as an elastic portion that presses the hook member 71 toward the concave portion 141 of the lid body 14 are provided.

The hook member 71 includes an input portion 712 that is pushed in by a human hand, a locking claw 711 formed at the front end portion of the input portion 712, and extends from the lower surface of the input portion 712 to the left and right at the tip portion. A support arm 713 that is rotatably supported inside the apparatus main body 12 is integrally formed around the axis along the axis.
In FIG. 5, the position of the locking claw 711 when the hook member 71 is not pushed is indicated by a solid line, and the position of the locking claw 711 when the push operation is performed is indicated by a two-dot chain line. ing. The position indicated by the solid line is referred to as a “locking position” where the locking claw 711 restrains the lid body 14 in the tilted state, and the position indicated by the two-dot chain line is referred to as a “release position” where the position is released from the restrained state. The “release position” is a position where the tip of the locking claw 711 does not reach the end surface of the rotating end of the lid body 14 slightly.
That is, the locking claw 711 is provided in the apparatus main body 12 so as to be movable between the “locking position” and the “release position” depending on whether or not the hook member 71 is pushed into the input portion 712.

  The input unit 712 is a member having an upper surface exposed to the outside from the upper surface of the rear end of the apparatus main body 12 and having a substantially arcuate side view and a predetermined width in the left-right direction. is there. The upper surface of the input unit 712 is a moderately curved peripheral surface, and a groove that is gently depressed over the entire width in the left and right direction is provided at the center portion in the front-rear direction so that the finger can be easily applied during the pushing operation. Is formed.

  The locking claw 711 is formed at the front end portion of the input portion 712 over the entire left and right width, and is formed in a wedge shape that is sharpened forward. When the latching claw 711 is in the latched position, the lower surface of the latching claw 711 is substantially horizontal, and the upper surface is gently inclined with the front lowered.

  The support arm 713 has a shape that extends downward from the lower surface of the input portion 712 and then extends forward through a bent portion, and a front end portion thereof is supported inside the apparatus main body 12 so as to be rotatable about a left-right axis. ing. That is, there is a fulcrum of rotation on the front and lower side with respect to the input unit 712, so that the locking claw 711 is positioned at the locking position and the rear (strictly somewhat lower). It is possible to move between.

  The spring 72 is disposed below the input unit 712 and presses the input unit 712 upward. By the pressing of the spring 72, the locking claw 711 is pressed from the release position to the locking position side. Note that the locking claw 711 has its input portion 712 abutted against the inner wall of the apparatus main body 12 when the spring 72 is pressed, and its most advanced position is defined. The most advanced position is the locking position.

  A rectangular concave portion 141 is formed on the end surface of the rotating end portion of the lid body 14. Among the plurality of inner surfaces of the concave portion 141, in the tilted state of the lid body 14 with the display panel 16 facing upward, A plane located on the side is a locked surface 142. The locked surface 142 is disposed so as to be parallel to and in close proximity to the lower surface of the locking claw 711 at the locking position when the lid body 14 is tilted. In this state, the lid body 14 stands upright. The rotation to the state is restricted and the rotation is restricted.

[Pressure mechanism]
FIG. 6 is a cross-sectional view taken along line WW in FIG.
At the rear end of the apparatus main body 12, pressurization mechanisms 80 and 80 as pressurization units are provided on both the left and right sides of the fixing mechanism 70. 6 illustrates the left pressure mechanism 80, the right pressure mechanism 80 has the same structure.
The pressurizing mechanism 80 includes a convex body 81 and a spring 82 as a pressing portion that presses upward from the lower side of the convex body 81.
The convex body 81 has an oval shape in plan view, and an oval through-hole 121 formed at a position facing the rotation end portion of the above-described tilted lid body 14 at the rear end portion of the apparatus main body 12. Is inserted from below. Further, the convex body 81 has a flange 811 formed at the lower end thereof, and the flange 811 serves as a stopper to restrict upward protrusion from the through hole 121.

Then, the upper end portion of the convex body 81 comes into contact with the rotating end portion of the lid body 14 from below, and the rotating end portion of the lid body 14 in the tilted state is lifted from the tilted position by the pressure of the spring 82. It is possible to move by a predetermined amount (a stroke from the state in which the convex body 81 does not protrude to the maximum protruding position).
As the spring 82, a spring 82 having an elastic force capable of pushing up the lid body 14 to the maximum projecting position where the convex body 81 is regulated by the flange 811 by the resultant force of the two pressure mechanisms 80 is used.

  Further, the maximum projecting position of the convex body 81 is a position where the tilted lid body 14 is rotated to the upright side until the locked surface 142 of the lid body 14 cannot be locked by the locking claws 711. And In other words, the maximum protruding position of the convex body 81 is at least higher than the position at which the lid 14 can be pushed up to a position where the locked surface 142 of the lid 14 is above the lower surface of the latching claw 711. That is necessary.

[Rotation of the lid of the ultrasonic diagnostic equipment]
A rotation operation of the lid 14 of the ultrasonic diagnostic imaging apparatus 10 having the above configuration will be described with reference to FIGS.
When the lid body 14 is rotated from the standing state shown in FIG. 1 to the tilted state shown in FIG. 3, the lid body 14 is rotated on the upper surface of the latching claw 711 of the hook member 71 that is maintained by the spring 72. The end face corner of the moving end abuts. Since the upper surface of the locking claw 711 is inclined forward and obliquely downward, the hook member 71 rotates in the clockwise direction in FIG. 5 when the lid 14 abuts from above and receives downward pressing force. The locking claw 711 is pushed back to the release position side against the spring 72. Thereby, the corner | angular part of the cover body 14 passes the front-end | tip of the latching claw 711, and the cover body 14 rotates to a tilt position.

At this time, in each pressurizing mechanism 80, the rotating end portion of the lid body 14 abuts on the upper end portion of the convex body 81, and the convex body 81 is pushed downward against the pressing force of the spring 82.
Then, the locking claw 711 enters the concave portion 141 of the lid body 14 by the pressing force of the spring 72 and returns to the locking position again. At this time, the lower surface of the locking claw 711 is close to and opposed to the locked surface 142 and restrains the lid body 14 in a tilted state.

In order to rotate the lid 14 from the tilted state to the standing state, first, the input unit 712 of the fixing mechanism 70 is pressed downward. As a result, the locking claw 711 moves rearward together with the input unit 712 to the release position.
As a result, the lid 14 is released from the restraint on the locked surface 142, and the lid body 14 is pushed up to the maximum projecting position by the convex bodies 81, 81 of the two pressure mechanisms 80. As a result, the locked surface 142 moves above the locking claw 711, so that the lid 14 is not restrained by the locking claw 711 even when the pressing operation of the input unit 712 is stopped.
Accordingly, since it is not necessary to rotate the lid 14 with the other hand while holding the input unit 712 with one hand, the operation from the input operation of the input unit 712 to the pivoting operation to the standing position of the lid 14 can be performed with one hand. It can be done easily.

[Technical effects of ultrasonic diagnostic imaging equipment]
As described above, in the ultrasonic diagnostic imaging apparatus 10, the locking claw 711 can move between the locking position and the release position, and the surface to be locked is placed in the concave portion 141 at the rotation end of the lid body 14. 142 is formed, and includes a pressurizing mechanism 80 that pressurizes the tilted lid body 14 toward the standing state.
For this reason, when the lid 14 is tilted, it can be maintained in the tilted state unless the locking claw 711 locks the locked surface 142 and operates the input unit 712. Therefore, when the ultrasonic diagnostic imaging apparatus 10 is carried or transported, it is possible to prevent the lid 14 in a tilted state from being accidentally rotated, and to reduce the occurrence of dropping or the like.

  Further, when the lid 14 is rotated from the tilted state to the standing state, when the input portion 712 is operated to bring the locking claw 711 into the release position, the pressurizing mechanism 80 causes the protruding body 81 to project according to the protruding amount. The lid body 14 is pushed up from the tilted state to the standing state side, and the locking claw 711 cannot lock the locked surface 142. Therefore, it is not necessary to rotate the lid body 14 while holding the input unit 712, and the pivoting operation of the lid body 14 can be performed very easily. In addition, the lid 14 can be easily raised from the tilted state with only one hand.

In addition, the fixing mechanism 70 includes a spring 72 that presses the locking claw 711 toward the locking position via the input unit 712, and the protruding mechanism according to the rotation of the lid body 14 from the standing state to the tilted state. After the pawl 711 is pushed back once, it is restored by the elastic force of the spring 72 to lock the locked surface 142.
For this reason, if the lid body 14 is rotated to the tilted position without operating the input unit 712, the fixing mechanism 70 automatically restrains the lid body 14, so that the pivoting operation of the lid body 14 is very difficult. It can be easily performed. In addition, the lid 14 can be easily tilted from the standing state with only one hand.

The pressurizing mechanism 80 includes a spring 82 that presses the rotating end of the tilted lid body 14 via the convex body 81. Since various spring constants are easily available, the spring 82 can be appropriately pushed up by appropriately selecting the spring 82, so that the cover 14 can be moved from the tilted state. It is possible to improve the certainty of the turning operation to the standing state.
Further, since the pressurizing mechanism 80 performs the push-up operation by the spring 82 at a position close to the locked surface 142, a design error and a shortage of the push-up operation amount due to bending of each part of the lid body 14 hardly occur. Further, it is possible to improve the certainty of the rotation operation of the lid body 14 from the tilted state to the standing state.

[Rotation when the lid is turned upside down]
As described above, the lid body 14 can be rotated 180 ° around the vertical axis V to invert the front and back, and the display panel 16 can be tilted downward.
As shown in FIG. 7, when the display panel 16 is tilted downward, another one is placed in the recess 141 of the lid 14 so as to face the lower surface of the locking claw 711 at the locking position. You may form the to-be-latched surface 143 as a to-be-latched part.
Thereby, it is possible to easily perform the rotation operation of the lid body 14 to the standing state and the rotation operation to the tilted state by the same operation as when the lid body 14 is not reversed even when the lid body 14 is reversed. In any of these cases, one-handed operation is possible.

[Other examples of pressurizing section (1)]
The pressurizing unit is not limited to the pressurizing mechanism 80 shown in FIG.
For example, the pressurizing unit may be formed of a spring material that applies an elastic force from the tilted state to the upright side with respect to the lid body 14 on the pivot point side of the lid body 14.
Specifically, the horizontal arm 63 of the hinge 60 is formed from an elastically deformable spring material without providing the pressurizing mechanism 80, and the horizontal arm 63 is rotated by rotating the lid body 14 from the standing state to the tilted state. As shown in FIG. 8, elastic torsional deformation occurs between the connection position with the rotation shaft 64 and the connection position with the mounting plate 61, and an elastic force from the tilted state to the standing state side is generated. . When the locking claw 711 of the fixing mechanism 70 locks the locked surface 142 of the lid body 14 in a state where this elastic force is generated, the lid body 14 is rotated when the lid body 14 is rotated from the tilted state to the standing state. By simply moving the pawl 711 to the release position, the lid body 14 automatically rotates to the standing state side, and the lid body 14 can be rotated very easily from the tilted state to the standing state. It becomes possible. In addition, the lid 14 can be easily tilted from the standing state with only one hand.
In this case, the hinge 60 is provided with a torque limiter 62 and is configured to require a predetermined torque for the rotational operation of the lid body 14, so that the elastic deformation of the horizontal arm 63 that is a spring material is more effectively generated. The effect as a pressurizing part is heightened.

Further, instead of using the horizontal arm 63 of the hinge 60 as a spring material, two mounting plates 61 are formed of a spring material, and the arm of the mounting plate 61 is used when the lid 14 is rotated from the standing state to the tilted state. 61b may be elastically deformed to generate an elastic force from the tilted state to the standing state. Also in this case, the presence of the torque limiter 62 is useful.
The spring material of the horizontal arm 63 or the mounting plate 61 and the above-described pressurizing mechanism 80 may be used in combination.
In addition, the spring material mentioned above shall show all the materials which can produce an elastic deformation.

[Other examples of pressure unit (2)]
For example, the pressurizing unit may be configured to pressurize the lid body 14 toward the upright side using flexibility of the lid body 14 itself.
Specifically, without providing the pressurizing mechanism 80, as shown in FIG. 9, a protrusion 122 is provided on the upper surface of the apparatus main body 12 so as to be in contact with the lid body 14, and the lid body 14 is tilted from an upright state. When the lid body 14 is rotated to the state, the lid body 14 is rotated to a position where it is still tilted even if it abuts against the protrusion 122, and is locked by the locking claw 711 of the fixing mechanism 70.
Thereby, the lid body 14 is bent and deformed by its flexibility, and an elastic force from the tilted state to the standing state side is generated.
Using this, when the lid body 14 is rotated from the tilted state to the standing state, the lid body 14 is automatically rotated to the standing state side simply by moving the locking claw 711 to the release position. . The dotted line in FIG. 9 shows the position when the rotation is stopped without causing the bending deformation due to the flexibility at the position where the lid 14 is in contact with the protrusion 122. When the locking claw 711 is moved to the release position, the lid body 14 is rotated to the position of this dotted line. Therefore, it is possible to very easily turn the lid body 14 from the tilted state to the standing state. In addition, the lid 14 can be easily tilted from the standing state with only one hand.

It is desirable that the amount of deformation of the lid 14 be such that the display panel 16 is not affected. The lid 14 is preferably formed of a flexible material.
In addition, you may use together the structure which uses a spring material for each member of the pressurization mechanism 80 and hinge 60 which were mentioned above, and the pressurization part by the flexibility of the cover body 14.

[Others]
The spring 72 in the fixing mechanism 70 is not necessarily provided. In that case, it is desirable that the hook member 71 is provided with a friction body or the like that generates resistance in the rotation operation so that the locking claw 711 can maintain the locked position and the released position.
Even in the case where the spring 72 is not provided, it is possible to obtain the ease of rotating the lid body 14 from the tilted state to the standing state.

In addition, although the fixing mechanism 70 illustrated the case where the hook member 71 and the locking claw 711 were provided on the apparatus main body 12 side and the concave portion 141 and the locked surface 142 were formed on the lid body 14 side, The hook member 71 and the locking claw 711 may be provided, and the recess 141 and the locked surface 142 may be formed on the apparatus main body 12 side.
Further, the pressurizing mechanism 80 may be provided on the lid body 14 side and pressurize the lid body 14 from the tilted state to the standing state.
