Description

  The present invention relates to an ultrasonic diagnostic apparatus, and more particularly to a movable holding mechanism that holds a display that displays an ultrasonic image.

  In general, an ultrasonic diagnostic apparatus used in the medical field includes an apparatus main body, an ultrasonic probe that transmits and receives ultrasonic waves, a display that displays an ultrasonic image, and a movable holding mechanism that holds the display. Have The apparatus main body includes a cart unit in which a plurality of electronic circuit boards and a power supply unit are accommodated, an operation panel (including a switch, a pointing device, a rotary knob, a sub display, and the like). The movable holding mechanism is movable, so that a user such as a doctor or a nurse can set the display at an arbitrary position or posture.

  At the time of ultrasonic diagnosis, the user confirms an ultrasonic image obtained by ultrasonic waves transmitted and received by the ultrasonic probe with a display while applying the ultrasonic probe to the subject. At the time of diagnosis, the user often pays attention mainly to the ultrasonic probe or the subject, and the user's body is also directed to the subject. Under such circumstances, it is preferable that the display device can take a comfortable position or posture for the user so that the user can easily check the display device.

  Conventionally, techniques for changing the position or orientation of a display of an ultrasonic diagnostic apparatus have been proposed. For example, Patent Document 1 discloses a movable holding mechanism that holds a display, and a main base (lower arm) that is pivotably attached to an ultrasonic diagnostic apparatus main body, and a distal end as viewed from the main base apparatus main body. A movable holding mechanism is disclosed that includes an upper arm pivotably attached to the frame.

Special table 2007-520304 gazette

  There are cases where the ultrasonic diagnostic apparatus main body cannot be arranged in a predetermined area, for example, a sterilization area such as a surgical field. Therefore, when an ultrasonic diagnostic apparatus is used during surgery, a doctor may operate an ultrasonic probe in the operation field, and a nurse or the like may operate the operation panel according to the doctor's instructions. . In such a case, it is desired to further expand the movable range of the display so that a doctor located at a position away from the apparatus main body can suitably check the ultrasonic image.

  Further, for example, in a movable holding mechanism composed of a plurality of arm members that can be turned in a horizontal direction, such as the movable holding mechanism disclosed in Patent Document 1, the position or posture of the display is changed by the turning movement of each arm member. Be made. In such a structure, when the display is pulled out in the pulling direction (for example, the front direction), if a plurality of arms are arranged to extend in a direction parallel to the pulling direction, a force in the pulling direction is applied. However, each arm cannot turn and the display cannot be moved in the pull-out direction. In such a case, it is necessary to move the indicator once in a direction different from the pull-out direction (for example, the horizontal direction), slightly rotate at least one of the plurality of arms, and then apply a force in the pull-out direction. . As described above, in the conventional movable holding mechanism, depending on the state of each arm, in order to move the display device in the pull-out direction, it is necessary to move the display device in a plurality of directions. Met.

  An object of the present invention is to expand the movable range of the display of the ultrasonic diagnostic apparatus as compared with the conventional case. Alternatively, an object of the present invention is to enable the display device to be easily pulled out in the pull-out direction regardless of the state of the movable holding mechanism that holds the display device.

  The ultrasonic diagnostic apparatus according to the present invention includes a pedestal provided in the apparatus main body, and a movable holding mechanism that holds a display that is mounted on the pedestal and displays an ultrasonic image, and the movable holding mechanism includes the pedestal. A pedestal side coupling portion coupled to the pedestal side, a first pivoting end portion horizontally spaced from the pedestal side coupling portion, and a first pivot arm pivotable about the pedestal side coupling portion; and a parallel link A first parallel link arm having a structure, comprising: a swivel arm side connecting portion connected to the first turning end portion; and a first rotating end portion separated from the turning arm side connecting portion; A first parallel link arm rotatable in a vertical plane around the swivel arm side connection portion; and a second parallel link arm having a parallel link structure, the first parallel link connected to the first rotation end portion A side connecting portion and the first parallel A second rotation end portion separated from the first side link portion, and a second parallel link arm rotatable in a vertical plane around the first parallel link side connection portion; and the second rotation end portion. And a display holding mechanism that holds the display and is provided between the display and the display.

  According to the said structure, a movable holding mechanism will be located in order of a 1st turning arm, a 1st parallel link arm, a 2nd parallel link arm, and an indicator holding mechanism seeing from a base. Each of the above members may be directly connected or indirectly connected. The first swivel arm can swivel in the horizontal plane, that is, the first swivel end moves on the circumferential track in the horizontal plane. Since the first parallel link arm is connected to the first swivel end, the first swivel arm performs a swiveling motion, so that the first parallel link arm and the second parallel link arm, the display holding mechanism, etc. Each member also turns together. Thereby, the movable range (especially horizontal movable range) of a display is expanded. Specifically, by turning the first swivel arm located closest to the pedestal of the movable holding mechanism, each of the members ahead (display side) can also be swung together. The movable range of is expanded.

  Preferably, the display holding mechanism includes a second parallel link side connection portion connected to the second rotation end portion, and a second turning end portion horizontally spaced from the second parallel link side connection portion. And a second swivel arm that can swivel about the second parallel link side connecting portion. According to the second swivel arm, the user can change the direction of the display (display surface) in the left-right direction after determining the position of the display.

  Preferably, the display holding mechanism includes a tilting mechanism for tilting the display up and down. According to the tilt mechanism, the user can suitably change the vertical direction of the display unit after determining the position of the display unit and the horizontal direction.

  Desirably, when the first parallel link arm and the second parallel link arm are aligned in a direction parallel to the pull-out direction of the display unit, a force to the display unit toward the front side in the pull-out direction is desirable. Is added, the indicator is pulled out to the near side by the rotational movement of the first parallel link arm.

  In the ultrasonic diagnostic apparatus according to the present invention, the first parallel link arm is rotatable on the vertical plane around the turning arm side connecting portion. Therefore, even when the first parallel link arm and the second parallel link arm are arranged in the pull-out direction of the display device, the user is in the pull-out direction (for example, the front side direction) with respect to the display device. By simply applying a force, the indicator can be pulled out in the pull-out direction by the rotational movement of the first parallel link arm.

  Preferably, the upper surface of the first swivel arm includes a first flat surface, and the lower surface of the second swivel arm positioned above the first swivel arm is joined to the first flat surface. including. Desirably, in a state where the first flat surface and the second flat surface are joined, the swivel motion of the first swivel arm and the second swivel arm, and the first parallel link arm and the second parallel link arm The rotational movement of the is regulated.

  Since the first swivel arm swivels in a horizontal plane, its upper surface is always kept horizontal. Since the second swivel arm is supported by the first parallel link arm and the second parallel link arm and swivels in the horizontal plane, the lower surface of the second swivel arm is always kept horizontal. The two surfaces can be used effectively. For example, a first flat surface is provided on the upper surface of the first swivel arm, a second flat surface is provided on the lower surface of the second swivel arm, and the first flat surface and the second flat surface are joined to each other, thereby being included in the movable holding mechanism. The movement of each member may be restricted. Such movement restriction of the movable holding mechanism is useful, for example, when housing an ultrasonic diagnostic apparatus.

  Preferably, in a state where the first flat surface and the second flat surface are joined, the first parallel link arm and the second parallel link arm are folded substantially in parallel. In a state where the first flat surface and the second flat surface are joined, the first parallel link arm and the second parallel link arm are folded substantially in parallel, that is, in a state in which the first flat surface and the second parallel link arm are lined up one above the other. It becomes more compact. Thereby, for example, the storage space can be narrowed.

  ADVANTAGE OF THE INVENTION According to this invention, the movable range of the indicator of an ultrasonic diagnosing device can be expanded conventionally. Alternatively, according to the present invention, the display can be easily pulled out in the pull-out direction regardless of the state of the movable holding mechanism that holds the display.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the drawings.

<Basic configuration of ultrasonic diagnostic equipment>
FIG. 1 is a perspective view of an ultrasonic diagnostic apparatus 10 according to the present embodiment. FIG. 2 shows a side view of the ultrasonic diagnostic apparatus 10. The ultrasonic diagnostic apparatus 10 is an apparatus that is used in the medical field, performs ultrasonic wave transmission / reception with respect to a living body (particularly a human body), takes a reception signal, and forms an ultrasonic image based on the reception signal. . 1 and 2, the left-right direction of the ultrasonic diagnostic apparatus 10 is defined as the X axis, the depth direction (front-rear direction) is defined as the Y axis, and the height direction is defined as the Z axis.

  The ultrasonic diagnostic apparatus 10 includes a main body 12, an arm mechanism 14, and a monitor 16.

  The main body 12 includes a base unit 18 having a box shape, a base plate 20 disposed below the base unit, four casters 22 disposed below the base plate 20, an operation panel plate 24, and an operation panel plate 24. An operation panel 26 placed on top and a sub-monitor 28 placed on the operation panel plate 24 are configured.

  A plurality of electronic circuit boards and a power supply unit are accommodated in the base unit 18. A plurality of probe connectors 18 a to which the ultrasonic probe is detachably connected are provided on the front side surface of the base unit 18. A handle 18b is formed at the rearmost portion of the upper side surface of the base unit 18 so as to stand upward from the upper side surface. The handle 18b is a portion that is gripped by the carrier when the ultrasonic diagnostic apparatus 10 is conveyed.

  The operation panel plate 24 has a flat portion 24 a for placing the operation panel 26 and the like, and the flat portion 24 a is connected to the base unit 18. Further, the operation panel plate 24 has an extending portion 24b extending from the flat portion 24a in the rear direction (Y-axis positive direction). A pedestal 24c (see FIG. 2) to which the arm mechanism 14 is coupled is provided on the upper surface of the rear end portion of the extending portion 24b. Further, the operation panel plate 24 has a plurality of probe holders 24d provided on both the left and right sides of the flat portion 24a. Further, the operation panel plate 24 has a handle 24e in front of the flat portion 24a.

  The operation panel plate 24 is connected to the base unit 18 so as to be able to move up and down and slide in the front-rear direction. Or you may turn in a horizontal surface. Thereby, the user can arbitrarily change the position or posture of the operation panel 26 or the sub monitor 28. The user can suitably change the position or posture of the operation panel plate 24 by grasping the handle 24e.

  The operation panel 26 has a plurality of switches or operation elements such as a trackball. By operating these operators, ultrasonic diagnostic conditions and the like are set. The sub monitor 28 is composed of, for example, a liquid crystal panel and displays ultrasonic diagnostic conditions and the like. The sub monitor 28 may be a touch panel. In this case, the user can input an instruction to the ultrasonic diagnostic apparatus 10 by touching the sub monitor 28.

  The monitor 16 includes a monitor device 16a including a display surface and a monitor housing 16b that wraps the monitor device 16a so that the display surface is exposed.

<Configuration of arm mechanism>
FIG. 3 is a rear perspective view of the arm mechanism 14 and the monitor 16. Further, FIG. 4 shows a side view of the arm mechanism 14. In FIG. 4, the monitor 16 is partially omitted. The arm mechanism 14 is movable, so that the user can arbitrarily change the position or posture of the monitor 16. The arm mechanism 14 is formed by connecting a plurality of motion members, and the position or posture of the monitor 16 is changed as each motion member moves. Hereinafter, details of each motion member included in the arm mechanism 14 will be described.

  The arm mechanism 14 is connected in turn from a pedestal 24 c provided on the operation panel plate 24 toward the monitor 16, and includes a turning base arm 30, a proximal parallel link 32, an intermediate turning arm 34, and a distal parallel link 36. The monitor-side swivel arm 38 is included. A cover 40 is provided between the proximal parallel link 32 and the intermediate turning arm 34. The cover 40 prevents the inner part of the arm mechanism from being visually recognized from the outside. In this specification, the term “proximal” means the pedestal 24c side in the connecting direction of the arm mechanism 14, and the term “distal” means the monitor 16 side in the connecting direction. In the present specification, the rotation on the horizontal plane is referred to as “swirl”, and the rotation on the vertical plane is referred to as “rotation”.

  The turning base arm 30 is connected to the base 24c. The pedestal 24 c has a substantially cylindrical shape, and a cylindrical hole is formed in the lower surface of the turning base arm 30. When the pedestal 24c is fitted into the hole via a bearing or the like, the turning base arm 30 is connected to the pedestal 24c so as to be rotatable about the first vertical axis 50.

  Since the turning base arm 30 performs a turning motion, the upper side surface 30a of the turning base arm 30 is always kept horizontal (including substantially horizontal). A pit 52 which is a recess is formed on the upper side surface 30a. The operation of the pit 52 will be described later.

  The proximal end of the proximal parallel link 32 is connected to the distal end of the pivot base arm 30. For example, a circular hole is formed in one of the turning base arm 30 and the proximal-side parallel link 32, and the shaft formed in the other is inserted into the hole to connect the two. Thereby, the proximal-side parallel link 32 can rotate in the vertical plane around the first horizontal axis 54 with respect to the turning base arm 30.

  The proximal parallel link 32 has a parallel link structure having two arms. Thereby, even if the proximal parallel link 32 rotates, the posture of each member connected to the distal side of the proximal parallel link 32 is maintained. Further, the proximal-side parallel link 32 has its own weight having a function of canceling gravity so that the monitor 16 does not move downward due to the action of gravity after the user releases the monitor 16. Compensation function is provided.

  An intermediate pivot arm 34 is connected to the distal end of the proximal parallel link 32. For example, a vertically extending substantially cylindrical shaft provided at the distal end of the proximal parallel link 32 is fitted into a circular hole formed in the lower surface of the intermediate pivot arm 34 via a bearing or the like. The two are connected. As a result, the intermediate pivot arm 34 can rotate in the vertical plane around the second vertical axis 56 with respect to the proximal parallel link 32. As described above, since the proximal parallel link 32 has a parallel link structure, the second vertical axis 56 always extends in the vertical direction regardless of the rotational movement of the proximal parallel link 32.

  The proximal end of the distal parallel link 36 is connected to the distal end of the intermediate pivot arm 34. For example, as with the connection between the pivot base arm 30 and the proximal parallel link 32, a circular hole is formed in one of the intermediate pivot arm 34 and the distal parallel link 36, and an axis formed on the other is formed in the hole. Both are connected by being inserted. As a result, the distal parallel link 36 can rotate in the vertical plane about the second horizontal axis 58 with respect to the intermediate pivot arm 34.

  Like the proximal parallel link 32, the distal parallel link 36 has a parallel link structure having two arms. Thereby, even if the distal side parallel link 36 rotates, the posture of each member connected to the distal side of the distal side parallel link 36 is maintained. The distal parallel link 36 is also provided with a self-weight compensation function having a function of canceling gravity.

  A monitor-side pivot arm 38 is connected to the distal end of the distal parallel link 36. For example, as with the connection between the proximal parallel link 32 and the intermediate pivot arm 34, the monitor pivot arm 38 is pivotally supported by the distal parallel link 36. As a result, the monitor-side swivel arm 38 can rotate in the vertical plane about the third vertical axis 60 with respect to the distal-side parallel link 36. In this embodiment, the monitor-side swivel arm 38 has an arm-like shape extending in the horizontal direction, but the monitor-side swivel arm 38 has, for example, a block-like shape instead of an arm-like shape. Also good.

  As described above, the proximal-side parallel link 32 and the distal-side parallel link 36 that perform rotational motion in the vertical plane both have a parallel link structure. Therefore, the monitor-side swivel arm regardless of the rotational motion. 38 postures are maintained. Thereby, the lower side surface 38a of the monitor-side swivel arm 38 is always kept horizontal (including substantially horizontal), and the third vertical axis always extends in the vertical direction. A lock block 62 is formed on the lower side surface 38a. The lock block 62 is provided directly below the third vertical shaft 60. The operation of the lock block 62 will be described later.

  The monitor 16 is connected to the distal end of the monitor-side pivot arm 38. For example, the monitor 16 is pivotally supported by the monitor-side swivel arm 38 as in the connection between the swivel base arm 30 and the proximal parallel link 32. As a result, the monitor 16 can rotate in the vertical plane about the third horizontal axis 64 with respect to the monitor-side turning arm 38. Thereby, the tilt angle adjustment motion (tilt motion) of the monitor 16 becomes possible. That is, a tilt mechanism for tilting the monitor 16 is formed between the monitor-side swivel arm 38 and the monitor 16, and the tilt mechanism of the monitor is enabled by the tilt mechanism. As described above, in the present embodiment, the display holding mechanism includes the monitor-side turning arm 38 and the tilt mechanism.

<Change in monitor position or posture due to movement of arm mechanism>
Hereinafter, a state in which the position or posture of the monitor 16 changes due to the movement of the arm mechanism 14 will be described with reference to FIGS.

  FIG. 5 shows the turning base arm 30 turning. The pivot base arm 30 has a reference position at a position (a position shown in FIG. 3) where a distal end thereof (a connection portion with the proximal parallel link 32) is disposed in the rearward direction of the first vertical axis 50. From the reference position, it can turn up to 120 degrees counterclockwise in plan view. FIG. 5A shows a state in which the turning base arm 30 is turned to the maximum in the counterclockwise direction. In FIG. 5A, the orientation of the display surface of the monitor 16 is kept forward by the turning motion of the intermediate turning arm together with the turning motion of the turning base arm 30. Of course, as the turning base arm 30 turns, other members may also turn or rotate, and the monitor 16 can take various positions or postures.

  In particular, the pivot base arm 30 located on the most proximal side of the arm mechanism 14 pivots, so that each member located on the distal side also pivots together. That is, by making the most proximal member of the arm function pivotable, the movable range (especially the movable range in the horizontal direction) of the monitor 16 can be further expanded.

  The turning base arm 30 can turn at a maximum of 120 degrees in the clockwise direction in plan view from the reference position. FIG. 5B shows a state in which the turning base arm 30 is turned to the maximum in the clockwise direction.

  FIG. 6 shows how the proximal parallel link 32 rotates. When the proximal side parallel link 32 stands vertically (state in which the angle formed by the turning base arm 30 and the proximal side parallel link 32 is 90 degrees) is a reference position, the proximal side parallel link 32 32 can rotate 45 degrees in the rear direction from the reference position, and can rotate 30 degrees in the front direction from the reference position.

  For example, the movement of the monitor 16 in the front-rear direction is realized by the rotational movement of the proximal parallel link 32. In FIG. 6, the state of the proximal parallel link 32 rotated 45 degrees in the rearward direction from the reference position is indicated by reference numeral 32A, and the position of the monitor 16 at that time is indicated by position 16A. The state of the proximal parallel link 32 rotated 30 degrees in the forward direction from the reference position is indicated by reference numeral 32B, and the position of the monitor 16 at that time is indicated by position 16B. The change from the position 16 </ b> A to the position 16 </ b> B of the monitor 16 shown in FIG. 6 is a change in position when only the proximal parallel link 32 moves in the arm mechanism 14. In this case, the motion trajectory of the monitor 16 has an arc shape according to the rotational motion of the proximal parallel link 32. As described above, since the proximal parallel link 32 has a parallel link structure, the posture of the monitor 16 does not change even if the proximal parallel link 32 rotates.

  Since the proximal parallel link 32 is rotatable, the monitor 16 can be moved even when the proximal parallel link 32 and the distal parallel link 36 are arranged in parallel with the pull-out direction of the monitor 16. It can be preferably pulled out in the pulling direction. For example, even if the proximal parallel link 32 and the distal parallel link 36 are both aligned in the front-rear direction (Y-axis direction) as in the state shown in FIGS. When pulling out the lens to the front side (Y-axis negative direction side), the monitor 16 is pulled out to the front side by rotating the proximal parallel link 32 only by applying a force in the front side direction.

  In addition, the operation feeling given to the user when pulling out the monitor 16 is further improved by setting the rotation in the rearward direction of the proximal parallel link 32 to 45 degrees from the reference position. Specifically, when the proximal parallel link 32 is tilted more than 45 degrees in the rearward direction, when the monitor 16 is pulled out from the state, the user is more likely to raise the collapsed proximal parallel link 32 with respect to the monitor 16. A lot of power needs to be applied. Specifically, it is necessary to apply more force to the monitor 16 in the upward direction than in the pull-out direction. If the tilt angle of the proximal parallel link 32 to the rear side is within 45 degrees, the force in the upward direction may be equal to or less than the force in the pull-out direction, so that the user can pull out the monitor more suitably. it can.

  FIG. 7 shows how the distal parallel link 36 rotates. When the distal parallel link 36 is maintained in the horizontal direction as a reference position, the distal parallel link 36 can be rotated 30 degrees upward from the reference position, and the distal parallel link 36 can be moved downward from the reference position. Can be rotated 45 degrees.

  In FIG. 7, the state of the distal parallel link 36 rotated 30 degrees upward from the reference position is indicated by reference numeral 36A, and the position of the monitor 16 at that time is indicated by position 16C. The state of the distal parallel link 36 rotated 45 degrees downward from the reference position is indicated by reference numeral 36B, and the position of the monitor 16 at that time is indicated by position 16D. The change from the position 16C to the position 16D of the monitor 16 shown in FIG. 7 is a change in position when only the distal parallel link 36 moves in the arm mechanism 14. Also in this case, the movement locus of the monitor 16 becomes an arc shape according to the rotational movement of the distal parallel link 36. As described above, since the distal parallel link 36 has a parallel link structure, the posture of the monitor 16 does not change even if the distal parallel link 36 rotates.

  Further, the movable range of the monitor 16 in the upward direction is further expanded by the cooperation of the rotational motion of the distal parallel link 36 and the rotational motion of the proximal parallel link 32. When the proximal parallel link 32 is erected in the vertical direction and the distal parallel link 36 is rotated to the maximum (30 degrees) upward from the reference position, the monitor 16 is at the maximum position. Be placed.

  FIG. 8 shows how the monitor-side swivel arm 38 performs a swiveling motion. By the turning movement of the monitor-side turning arm 38, the swinging movement of the monitor 16 in the left-right direction is realized. If the reference position is a position where the display surface of the monitor 16 faces directly in front (the position of such a monitor is indicated by a position 16E in FIG. 8), the monitor-side turning arm 38 is counterclockwise in plan view from the reference position. It can be rotated about 80 degrees around, and can be rotated about 80 degrees clockwise from the reference position in plan view. In FIG. 8, the position of the monitor 16 when the monitor-side swivel arm 38 is rotated about 80 degrees counterclockwise from the reference position is indicated by a position 16F, and when the monitor-side turning arm 38 is rotated about 80 degrees clockwise from the reference position. The position of the monitor 16 is indicated by a position 16G.

  FIG. 9 shows a state in which the monitor-side swivel arm 38 is tilted. In FIG. 9, the reference direction in which the display surface of the monitor 16 is parallel to the vertical surface is indicated by a state 16H, and the state in which the monitor 16 is directed downward as much as possible is indicated by a state 16I. The state facing upward as much as possible is shown by state 16J. By the tilting movement of the monitor 16, the display surface of the monitor 16 can be tilted downward by about 10 to 15 degrees and tilted upward by about 55 degrees. When the monitor 16 is set to a relatively high position by the arm mechanism 14, the visibility of the display surface can be improved by tilting the monitor 16 downward. In addition, since the tilting can be greatly performed on the upper side, the monitor 16 does not block the field of view of the transporter when the ultrasonic diagnostic apparatus 10 is transported, and the transporter can preferably visually recognize the front end of the apparatus. In addition, the ultrasonic diagnostic apparatus 10 can be collected more compactly during storage.

  In addition to the above, the arm mechanism 14 has a roll mechanism (not shown) that causes the monitor 16 to roll. The roll motion is a motion that tilts the monitor 16 left and right. For example, when the display surface of the monitor 16 is kept parallel to the vertical surface, the monitor 16 tilts the monitor 16 left and right on the vertical surface. According to the roll mechanism of the present embodiment, the monitor 16 can be tilted by 1.5 degrees left and right from the horizontal direction. Thereby, the fine adjustment of the inclination of the monitor 16 in the left-right direction can be performed.

  FIG. 10 shows the state of the arm mechanism 14 and the monitor 16 in the folded state. After the arm mechanism 14 and the monitor 16 are folded as shown in FIG. 10, the apparatus is transported or stored. In the folded state, the turning base arm 30 is arranged at the reference position. The proximal parallel link 32 is rotated maximally (about 45 degrees) rearward and the distal parallel link 36 is rotated maximally (about 45 degrees) downward. The monitor-side swivel arm 38 is disposed at the reference position, and the monitor 16 is tilted upward to the maximum. Thereby, in the folded state, the turning base arm 30 and the monitor-side turning arm 38 are in a state of being overlapped vertically. Further, the proximal-side parallel link 32 and the distal-side parallel link 36 are also arranged in an overlapping manner. Thus, in the folded state, the arm mechanism 14 and the monitor 16 are folded compactly.

  In the folded state, the upper side surface 30a of the turning base arm 30 and the lower side surface 38a of the monitor-side turning arm 38 are joined. Specifically, the upper side surface is obtained by inserting the lock block 62 (see FIG. 4) provided on the monitor-side turning arm 38 into the pit 52 (see FIG. 3) provided on the upper side surface 30a of the turning base arm 30. 30a and the lower surface 38a are joined. As will be described later, when the lock block 62 is inserted into the pit 52, the turning motion and the rotational motion of each member of the arm mechanism 14 are restricted.

  FIG. 11 shows a side view of the ultrasonic diagnostic apparatus 10 in the folded state. As described above, at the time of transport, the transporter stands on the back side of the ultrasonic diagnostic apparatus 10, grasps the handle 18 b, and pushes and moves the ultrasonic diagnostic apparatus 10. In the folded state, since the arm mechanism 14 and the monitor 16 are folded, the transporter is not obstructed by the monitor 16 and the frontmost part of the ultrasonic diagnostic apparatus 10 (the frontmost part of the operation panel plate 24) is Visible. Thereby, the risk of damage at the time of conveyance of ultrasonic diagnostic equipment 10 is reduced.

  Specifically, the operation panel plate 24 is connected by a straight line from the viewpoint position A, when the distance H is the distance L from the rearmost part of the ultrasound diagnostic apparatus 10 and the position of the height H is the viewpoint position A of the carrier. The monitor 16 and the arm mechanism 14 are accommodated in a space below the line of sight E of the carrier. In this embodiment, the distance L is about 200 [mm], and the height H is about 1500 [mm]. Thereby, most transporters can visually recognize the front end of the operation panel plate 24 during transport.

<Lock mechanism>
As described above, when the lock block 62 provided on the monitor-side turning arm 38 is inserted into the pit 52 provided on the upper side surface 30a of the turning base arm 30, the turning motion and the rotational motion of each member are regulated. The According to the movement restriction mechanism of the ultrasonic diagnostic apparatus 10, the movement of the plurality of members of the arm mechanism 14 is restricted only by performing one operation of inserting the lock block 62 into the pit 52. Hereinafter, the motion restriction mechanism will be specifically described.

  FIG. 12 shows an enlarged perspective view of the upper side surface 30 a of the turning base arm 30. As described above, the pit 52 is provided on the upper side surface 30a. The pit 52 is a substantially rectangular parallelepiped hole (concave portion) and has a shape extending in the front-rear direction. The pit 52 has a front side wall, a rear side wall, a left side wall, a right side wall, and a bottom surface.

  The pit 52 has a substantially rectangular parallelepiped hollow portion 70 that is further hollowed leftward from the left side wall in the vicinity of the center in the front-rear direction. A lock claw 72 is provided in the cut-out portion 70. The lower right end side of the lock claw 72 is notched, thereby forming a jaw 72a. On the upper side surface of the jaw portion 72a, an inclined surface 72b facing the upper side and the right side is provided. The lock claw 72 is slidable in the left-right direction. The lock claw 72 is provided with an elastic member (in this embodiment, a coil spring, not shown in FIG. 12, see FIG. 15), and the lock claw 72 is urged rightward by the elastic member. Thereby, in a state where no force is applied to the lock claw 72 from the outside, a part of the lock claw 72 including the jaw portion 72 a enters the pit 52 from the cut-out portion 70.

  A lock release switch 74 is provided on a side portion (right side portion in the present embodiment) of the turning base arm 30. The lock release switch 74 moves in the left-right direction in conjunction with the lock pawl 72. The operation of the lock release switch 74 will be described later. Further, a part of the turning restriction pin 76 of the turning base arm 30 protrudes upward from the bottom surface of the pit 52. The operation of the turning restriction pin 76 will be described later.

  FIG. 13 shows an enlarged perspective view of the lock block 62 provided on the lower side surface of the monitor-side turning arm 38. In FIG. 13, the housing of the monitor-side turning arm 38 is not shown. The lock block 62 has a substantially rectangular parallelepiped shape, and has an opening 80 that opens toward the left side. A tilt regulating bolt 82 is provided in the opening 80. The tilt regulating bolt 82 is pivotally supported by the block housing 86 so as to be rotatable on a vertical plane (XZ plane) around a horizontal axis 84 extending in the front-rear direction (Y-axis direction). The lower portion of the tilt regulating bolt 82 is biased toward the left side, that is, the opening side of the opening 80 by an elastic member (in this embodiment, a torsion spring 88). The upper part of the tilt restricting bolt 82 is connected to two tilt restricting plates 90 provided on the left and right sides of the monitor side turning arm 38 above the lock block 62.

  FIG. 14 shows an enlarged view of the tilt regulating plate 90. Also in FIG. 14, illustration of the housing of the monitor-side turning arm 38 is omitted. FIG. 14 shows only the left tilt restriction plate 90 of the two tilt restriction plates 90, but the same restriction plate is provided on the right side. Since the structure and operation of the two tilt restriction plates 90 are the same, only the tilt restriction plate 90 on one side will be described below.

  The tilt regulating plate 90 is a plate-like member that extends in the front-rear direction. The tilt regulating plate 90 is pivotally supported on the side of the support 38b of the monitor-side turning arm 38 so as to be rotatable on a vertical plane (YZ plane) about a horizontal axis 92 extending in the left-right direction (X-axis direction). . The tilt restricting plate 90 is urged toward the upper side by the elastic member (not shown) such as a torsion spring. Thereby, in a state where the tilt lock is not performed, the tilt regulating plate 90 is maintained in a posture in which the front portion is positioned slightly below the rear portion. The rear part of the tilt regulating plate 90 is connected to the upper part of the tilt regulating bolt 82.

  A long hole 94 is provided in the front portion of the tilt regulating plate 90. The long hole 94 is formed obliquely with respect to the longitudinal direction of the tilt regulating plate 90, and extends obliquely downward as it advances to the front side. A cylindrical tilt regulating shaft 96 extending in the left-right direction is inserted into the long hole 94. The tilt regulating shaft 96 is also inserted into a long hole (not shown in FIG. 14, refer to FIG. 17) provided in the support body 38b of the monitor-side turning arm 38. The long holes provided in the support 38b are formed obliquely with respect to the horizontal direction, and unlike the long holes 94 of the tilt restricting plate 90, they extend obliquely upward as they move forward. Therefore, in a state where the tilt is not locked, the tilt restricting shaft 96 is not moved in the long hole 94 of the tilt restricting plate 90 by the lower end of the long hole provided in the support 38b, as shown in FIG. Held in the indicated position.

  A substantially circular rotating plate 100 is provided in front of the tilt regulating plate 90 in a side view. Two rotating plates 100 are provided corresponding to the two tilt regulating plates 90. The rotating plate 100 rotates around the third horizontal axis 64 (see FIG. 4) in conjunction with the tilt movement of the monitor 16. A cutout 100 a is provided on the outer peripheral portion of the rotating plate 100. Since the notch 100a is fitted with the tilt restricting shaft 96 when the tilt motion of the monitor 16 is restricted, the notch 100a has a shape (semicircular shape) along the shape of the tilt restricting shaft 96.

  FIG. 15 shows a state where the lock block 62 is inserted into the pit 52 (locked state). That is, the joining state of the turning base arm 30 and the monitor-side turning arm 38 is shown. When the lock block 62 approaches the pit 52 from above, first, the left end portion of the bottom surface of the lock block 62 comes into contact with the inclined surface 72 b of the lock claw 72. When the lock block 62 is further pressed downward after the contact, the inclined surface 72b receives a force from the lock block 62 in the downward and leftward directions. As a result, the coil spring 72c contracts and the lock pawl 72 moves to the left.

  When the lock block 62 further descends while pushing the lock claw 72 to the left side and the bottom surface of the lock block 62 and the bottom surface of the pit 52 come into contact with each other, the lock block 62 is provided with an opening 80, so that the lock block 62 is locked. The pushing force to the left of the claw 72 is released, and the lock claw 72 moves to the right side, that is, toward the original position by the force of the coil spring 72c. As a result, the jaw 72 a of the lock claw 72 enters the opening 80 of the lock block 62. Then, the lower side surface of the jaw 72 a of the lock claw 72 and the bottom surface 80 a of the opening 80 are in contact with each other, that is, the jaw 72 a is hooked on the opening 80. Thereby, the joining state of the turning base arm 30 and the monitor-side turning arm 38 is locked. Thus, in this embodiment, the lock mechanism that locks the engagement state between the lock block 62 and the pit 52 includes the lock claw 72 and the opening 80.

  As described above, the lock block 62 is provided directly below the third vertical axis 60 that is the pivot axis of the monitor-side pivot arm 38. As a result, when the lock block 62 is inserted into the pit 52, the load (bending load) applied to the monitor-side turning arm 38 due to the user pressing the monitor-side turning arm 38 against the turning base arm 30 from above is reduced. The

  In the joined state shown in FIG. 15, the bottom surface of the lock block 62 is in contact with the bottom surface of the pit 52, so that the downward movement of the lock block 62 is restricted, and the lock claw 72 is caught in the opening 80. Therefore, the upward movement of the lock block 62 is restricted thereby. Since the vertical movement of the monitor-side swivel arm 38 relative to the swivel base arm 30 is realized by the rotational movement of the distal parallel link 36, the lock block 62 is locked by the lock pawl 72, and thus the distal parallel movement is performed. The rotational movement of the link 36 is restricted.

  In addition, since the lock block 62 is inserted into the pit 52, the front side surface of the lock block 62 abuts against the front side wall of the pit 52, so that the lock block 62 (that is, the monitor-side turning arm 38) is moved in the front direction. Movement is restricted. Similarly, when the rear side surface of the lock block 62 abuts against the rear side wall of the pit 52, movement in the rear side direction of the monitor side turning arm 38 is restricted. Since the movement in the front-rear direction of the monitor-side swivel arm 38 with respect to the swivel base arm 30 is realized by the rotational movement of the proximal-side parallel link 32, the lock block 62 is inserted into the pit 52, so The rotational movement of the link 32 is restricted.

  Further, since the lock block 62 is inserted into the pit 52, the right side surface of the lock block 62 abuts against the right side wall of the pit 52, so that the lock block 62 (that is, the monitor-side turning arm 38) moves in the right direction. Movement is restricted. Similarly, when the left side surface of the lock block 62 abuts against the left side wall of the pit 52, the movement of the monitor-side turning arm 38 in the left direction is restricted. Since the horizontal movement of the monitor-side turning arm 38 relative to the turning base arm 30 is realized by the turning movement of the intermediate turning arm 34 or the turning movement of the monitor-side turning arm 38, the lock block 62 is inserted into the pit 52. Thus, the turning motion of the intermediate turning arm 34 and the monitor-side turning arm 38 is restricted.

  Hereinafter, the operation of the tilt restricting mechanism that restricts the tilt motion of the monitor 16 will be described. In the joined state shown in FIG. 15, the lower portion of the tilt restricting bolt 82 disposed in the opening 80 is pushed in the right direction (inside the opening 80) by the jaw 72 a that has entered the opening 80. As a result, the tilt restricting bolt 82 rotates about the horizontal shaft 84, and thereby the upper portion of the tilt restricting bolt 82 moves in the left direction. In conjunction with the leftward movement of the upper portion of the tilt regulating bolt 82, the tilt regulating plate 90 connected to the upper portion of the tilt regulating bolt 82 is rotated. Specifically, referring to FIG. 16, the rear portion of tilt regulating plate 90 is pulled downward in conjunction with the rotation of tilt regulating bolt 82. As a result, the tilt restricting plate 90 rotates about the horizontal axis 92, whereby the front portion of the tilt restricting plate 90 moves upward.

  FIG. 17 shows an enlarged side view of the tilt regulating shaft 96. FIG. 17 shows a long hole 38 c provided in the support 38 b that is located inside the tilt regulating plate 90. With reference to FIGS. 16 and 17, the movement of the tilt regulating shaft 96 accompanying the rotation of the tilt regulating plate 90 will be described. When the front portion of the tilt restricting plate 90 moves upward, the tilt restricting shaft 96 is pushed up by the lower end of the elongated hole 94 of the tilt restricting plate 90 and obliquely moves upward in the elongated hole 38c provided in the support 38b. While moving upward in the direction, the inside of the long hole 94 moves obliquely downward.

  The state shown in FIG. 16 is a state in which the tilt regulating shaft 96 has moved forward until it comes into contact with the outer peripheral end of the rotating plate 100. In this state, the tilt motion of the monitor 16 has not been regulated yet, so to speak, it is a tilt motion regulation ready state. In this state, when the monitor 16 tilts (with the rotation of the rotating plate 100 and the position of the notch 100a varies), and the tilt angle of the monitor 16 is set to a predetermined angle, the tilt regulating shaft 96 is The rotary plate 100 is fitted into a notch 100a. The state shown in FIG. 17 is a state in which the tilt regulating shaft 96 is fitted in the notch 100a. As shown in FIG. 17, the positional relationship between the long hole 94 and the long hole 38c is changed by moving the front portion of the tilt regulating plate 90 upward. As a result, the tilt restricting shaft 96 is restricted by the lower end of the long hole 94 from moving obliquely downward (in the direction of returning to the position in the unlocked state) of the long hole 38c, and the tilt restricting shaft 96 and the notch 100a are The fitting state is maintained. With this state, the tilting motion of the monitor 16 is restricted.

  In the present embodiment, the tilt motion is restricted in a state where the monitor 16 is tilted upward to the maximum. As a result, assuming that the ultrasound diagnostic apparatus 10 is transported after the tilted state motion of the monitor 16 is restricted, the monitor 16 can always be tilted upward as much as possible during transport. it can. Thereby, at the time of conveyance, the posture of the monitor 16 is always kept in a posture suitable for conveyance of the apparatus as shown in FIG.

  As described above, the tilt restricting mechanism that restricts the tilt movement of the monitor 16 is formed across the lock block 62 and the tilt mechanism. Specifically, the tilt restricting mechanism includes a lock claw 72, a tilt restricting bolt 82, a tilt restricting plate 90, a tilt restricting shaft 96, and a notch 100a of the rotating plate 100, and the cooperation of these members. The tilt movement of the monitor 16 is restricted.

  Hereinafter, the operation of the base turning restriction mechanism that restricts the turning movement of the turning base arm 30 will be described. First, details of the turning restriction pin 76 that forms a part of the base turning restriction mechanism will be described. FIG. 18 shows the structure of the turning restriction pin 76. FIG. 18 (a) shows the state of the turning restriction pin 76 in the unlocked state, and FIG. 18 (b) shows the state of the turning restriction pin 76 in the locked state. In FIG. 18A, illustration of some members is omitted.

  The turning restriction pin 76 includes an upper pin 76a protruding upward from the bottom surface of the pit 52 (see FIG. 12) and a lower pin 76b protruding downward from the lower side surface of the turning base arm 30. The upper pin 76a and the lower pin 76b are substantially cylindrical. The upper pin 76a and the lower pin 76b are relatively movable up and down. Further, the turning restriction pin 76 includes an upper coil spring 76c that is an elastic member that urges the upper pin 76a upward, and a lower coil spring 76d that is an elastic member that urges the lower pin 76b upward. Thus, the upper coil spring 76c maintains the state in which the upper pin 76a protrudes upward from the bottom surface of the pit 52 in the unlocked state. Further, the lower coil spring 76d maintains a state where the lower pin 76b does not protrude downward from the lower side surface of the turning base arm 30 in the unlocked state. Further, the turning restriction pin 76 includes an intermediate coil spring 76e which is an elastic member having an action of pushing the lower pin 76b downward.

  Hereinafter, the operation of the turning restriction pin 76 will be described with reference to FIGS. FIG. 19 shows the state of the upper pin 76a in the unlocked state. In the unlocked state, the upper pin 76a is not pushed in by the lock block 62, and thus protrudes from the bottom surface of the pit 52 by the urging force of the upper coil spring 76c.

  FIG. 20 is a perspective view showing the lower side of the turning base arm 30 in the unlocked state. As shown in FIG. 19, the lower side surface of the lower pin 76b is exposed on the lower side surface 30b of the turning base arm 30, and the lower pin 76b can protrude from the lower side surface 30b. As described above, the pedestal 24 c is disposed on the lower side of the turning base arm 30. The pedestal 24c has a circular shape in plan view, and a cutout 110 is provided on the outer periphery of the pedestal 24c, like the above-described rotating plate 100. Since the notch 110 is a part into which the turning restriction pin is fitted when the turning movement of the turning base arm 30 is restricted, the notch 110 has a shape (semicircular shape) along the shape of the turning restriction pin.

  As shown in FIG. 20, in the unlocked state, the lower pin 76b does not protrude from the lower side surface 30b of the turning base arm 30 due to the urging force of the lower coil spring 76d. Therefore, the turning base arm 30 can turn with respect to the base 24c without being restricted in movement.

  FIG. 21 shows the state of the upper pin 76a in the locked state. In FIG. 21, the illustration of the lock block 62 is omitted. In the locked state, the upper pin 76a is pushed in by the lower surface of the lock block 62 and retracted downward.

  FIG. 22 is a perspective view showing the lower side of the turning base arm 30 in the locked state. In the locked state, the upper pin 76a is pushed in, whereby the intermediate coil spring 76e is contracted, and the lower pin 76b is pushed down by its elastic force. Thereby, the lower pin 76b protrudes downward from the lower side surface 30b. Then, the lower pin 76b protruding downward is fitted into the notch 110 of the pedestal 24c, whereby the turning motion of the turning base arm 30 relative to the pedestal 24c is restricted.

  As shown in FIGS. 20 and 22, the notch 110 is disposed directly behind the pedestal 24 c. Therefore, the turning base arm 30 is restricted from turning at the reference position. Of course, the position of the notch 110 may be appropriately determined in accordance with the position of the turning base arm 30 in the movement restricted state. When the upper pin 76a is pushed in when the turning base arm 30 is at a position other than the reference position, the lower side surface of the lower pin 76b comes into contact with the upper side surface of the base 24c. Even in this case, the intermediate coil spring 76e is contracted to allow the upper pin 76a to be pushed. In this state, the turning motion of the turning base arm 30 has not been restricted yet, so to speak, it is a turning motion restriction preparation state.

  In this state, when the turning base arm 30 turns and returns to the reference position, the lower pin 76b is pushed downward by the elastic force of the intermediate coil spring 76e, is fitted into the notch 110, and the turning base arm 30 The turning motion is restricted.

  FIG. 23 shows how the locked state is released. When the lock release switch 74 provided on the side portion of the turning base arm 30 is pushed to the left side, the lock claw 72 is also moved to the left side in conjunction therewith. As a result, the catch between the jaw 72a of the lock claw 72 and the opening 80 of the lock block 62 is released. That is, the locked state is released.

  When the lock release switch 74 is pushed in, the restriction of the vertical movement of the monitor-side turning arm 38 relative to the turning base arm 30 is released. That is, the restriction on the rotational motion of the distal parallel link 36 is released. Further, in the pushed state of the lock release switch 74, the push of the tilt restricting bolt 82 by the lock pawl 72 is released, and the tilt restricting plate 90 is rotated in conjunction with this, whereby the tilt restricting shaft 96 and the rotating plate 100 are turned off. The fitting with the notch 100a is released (see FIGS. 13 to 17). That is, the restriction on the tilt motion of the monitor 16 is released.

  When the lock block 62 is removed from the pit 52 due to the rotational movement of the distal parallel link 36, the movement of the lock block 62 is not restricted by the pit 52. That is, the restriction on the rotational movement of the distal parallel link 36, the restriction on the turning movement of the intermediate turning arm 34, and the restriction on the turning movement of the monitor-side turning arm 38 are released. When the lock block 62 is removed from the pit 52, the upper pin 76a of the turning restriction pin 76 is pushed upward by the elastic force of the upper coil spring 76c. Accordingly, the lower pin 76b moves upward by the elastic force of the lower coil spring 76d. Thereby, the restriction | limiting of the turning motion of the turning base arm 30 is cancelled | released.

  As described above, according to the motion restricting mechanism that restricts the motion of the arm mechanism 14 included in the ultrasonic diagnostic apparatus 10, the motion of the plurality of motion members included in the arm mechanism 14 can be achieved simply by inserting the lock block 62 into the pit 52. Is regulated. In particular, the swivel base arm 30 provided with the pit 52, the monitor-side swivel arm 38 provided with the lock block 62, and the movement members (proximal parallel link 32, intermediate swivel arm 34,. The movement of not only the distal side parallel link 36) but also the moving member (tilt mechanism) located closer to the monitor 16 than the monitor side pivot arm 38 is restricted. That is, since the user can restrict the movement of the plurality of movement members with one operation, it does not take time and effort to regulate the movement of the arm mechanism 14.

  Further, the engagement state between the lock block 62 and the pit 52 is locked, so that the engagement state can be suitably maintained. Furthermore, by providing the lock release switch 74, the user can release the locked state with one touch. Then, by simply removing the lock block 62 from the pit 52 with the lock released, the movement restriction of each movement member of the arm mechanism 14 is released. That is, it does not take time and effort to cancel the movement restriction of each movement member of the arm mechanism 14.

<Monitor housing structure>
Hereinafter, the structure of the monitor 16 of the ultrasonic diagnostic apparatus 10, in particular, the housing structure of the monitor 16 will be described.

  FIG. 24 is a rear perspective view of the monitor 16. FIG. 25 is a cross-sectional side view of the central portion in the left-right direction below the monitor 16. In FIG. 24, the arm mechanism is not shown.

  As shown in FIGS. 24 and 25, a lower ridge 120 extending in the left-right direction is provided on the lower edge of the back surface of the monitor housing 16 b of the monitor 16. The lower ridge 120 is provided over substantially the entire left and right direction of the monitor housing 16b. A horizontal groove 122 extending in the horizontal direction is formed immediately inside the lower protrusion 120 (the center side of the monitor 16) at the center in the left-right direction on the back surface of the monitor housing 16b. As shown in FIG. 25, the central portion of the lower ridge 120 is formed to protrude rearward from the bottom surface 122 a of the horizontal groove 122 in the central portion in the left-right direction.

  A right ridge 124 extending in the vertical direction is formed on the right (left side in FIG. 24) edge of the back surface of the monitor housing 16b. A right L-shaped groove 126 extending along the right edge and the lower edge of the monitor housing 16b is provided in the lower right portion of the monitor housing 16b. The right L-shaped groove 126 includes a horizontal groove 126 a extending along the inner side of the lower ridge 120 and a right vertical groove 126 b extending along the inner side of the right ridge 124. The right ridge 124 is formed so as to protrude rearward from the bottom surface 126 c of the right L-shaped groove 126. Further, the right side portion of the lower ridge 120 is also formed to protrude rearward from the bottom surface 126 c of the right L-shaped groove 126.

  Similarly, a left ridge 128 extending in the vertical direction is formed on the left (right side in FIG. 24) edge of the back surface of the monitor housing 16b. A left L-shaped groove 130 extending along the left side edge and the lower side edge of the monitor housing 16b is provided in the lower left portion of the monitor housing 16b. The left L-shaped groove 130 includes a horizontal groove 130 a extending along the inner side of the lower protrusion 120 and a left vertical groove 130 b extending along the inner side of the left protrusion 128. The left ridge 128 is formed so as to protrude rearward from the bottom surface 130 c of the left L-shaped groove 130. Further, the left portion of the lower protrusion 120 is also formed so as to protrude rearward from the bottom surface 130 c of the left L-shaped groove 130.

  Since the above-described structure is formed on the back surface of the monitor housing 16b, the user can preferably change the position or posture of the monitor 16. Specifically, the user can turn the finger from the lower side of the monitor 16 to the back surface of the monitor 16 and hook it on the lower ridge 120. As a result, the position or posture of the monitor 16 can be changed. At this time, the user's finger is preferably in contact with the bottom surface 122a of the horizontal groove 122, the bottom surface 126c of the horizontal groove 126a of the right L-shaped groove 126, or the bottom surface 130c of the horizontal groove 130a of the left L-shaped groove 130. The user can operate the monitor 16 more stably. In particular, when the monitor 16 is pulled out to the near side, the finger can be easily pulled out to the near side of the monitor 16 by pressing the finger against the bottom surface of the groove and applying a force to the near side.

  As described above, the lower hook structure includes the lower protrusion 120, the horizontal groove 122, the horizontal groove 126a of the right L-shaped groove 126, and the horizontal groove 130a of the left L-shaped groove 130.

  Further, the user can turn his / her finger from the right side of the monitor 16 to the back surface of the monitor 16 and hook it on the right ridge 124. At this time, preferably, the user's finger contacts the bottom surface 126c of the right vertical groove 126b of the right L-shaped groove 126, so that the user can operate the monitor 16 more stably. As described above, the right hook structure includes the right ridge 124 and the right vertical groove 126 b of the right L-shaped groove 126.

  Similarly, the user can turn his / her finger from the left side of the monitor 16 to the back side of the monitor 16 and hook it on the left ridge 128. At this time, preferably, the user's finger contacts the bottom surface 130c of the left vertical groove 130b of the left L-shaped groove 130, so that the user can operate the monitor 16 more stably. Thus, the left hook structure includes the left protrusion 128 and the left vertical groove 130b of the left L-shaped groove 130.

  By providing the right protrusion 124 and the left protrusion 128, the user can hook his / her finger not only on the lower edge of the back surface of the monitor housing 16b but also on the right edge and the left edge thereof. Thereby, the operability of the user's monitor 16 is further improved.

  The right vertical groove 126b (and the right ridge 124) is provided from the lower edge of the monitor housing 16b to a position 124a beyond the center in the vertical direction of the monitor housing 16b. Similarly, the left vertical groove 130b (and the left protrusion 128) is provided from the lower edge of the monitor housing 16b to a position 128a beyond the center in the vertical direction of the monitor housing 16b.

  If the right vertical groove 126b (and the right ridge 124) and the left vertical groove 130b (and the left ridge 128) are formed along substantially the entire right and left edges of the monitor housing 16b, the user's finger can be obtained. From the viewpoint of the operability of the monitor 16, this is desirable. However, the larger the right vertical groove 126b or the left vertical groove 130b, the narrower the internal space of the monitor housing 16b. The internal space is a space necessary for arranging components such as a substrate. Therefore, from the viewpoint of improving the operability of the monitor 16 while maintaining a certain amount of the internal space of the monitor housing 16b, the right vertical groove 126b and the left vertical groove 130b are part of the right and left edges of the monitor housing 16b. It is provided along. In particular, it is formed from a lower edge, which is considered to have a high frequency with which the user hooks a finger, to a certain position.

  As mentioned above, although embodiment which concerns on this invention was described, this invention is not limited to the said embodiment, A various change is possible unless it deviates from the meaning of this invention.
