Description

携帯型超音波診断装置Portable ultrasonic diagnostic equipment
　本発明は、携帯型の超音波診断装置に係り、特に、操作性に優れたコンパクトな携帯型超音波診断装置に関するものである。 The present invention relates to a portable ultrasonic diagnostic apparatus, and more particularly to a compact portable ultrasonic diagnostic apparatus with excellent operability.
　従来の超音波診断装置は、移動可能な台車に各種装置を搭載したワゴンタイプが主流であるが、可搬性に優れた携帯型超音波診断装置が知られている。この携帯型超音波診断装置は、薄型の本体筺体に対して表示装置を備えた蓋筺体を折りたたみ可能とするノートタイプがある。本体筺体の上面には操作部配置が形成され、この操作部配置を、表示装置を内面に備えた蓋筺体で覆うことで、この表示装置と操作部配置面を２つの筺体内に内在させて、可搬性に優れた形態としている。また、薄型の本体筺体の手前には、この本体筺体と一体形成される固定ハンドルを設け、この固定ハンドルを介して、可搬性を一層向上させている。 Conventional ultrasonic diagnostic apparatuses are mainly wagon types in which various devices are mounted on a movable carriage, but portable ultrasonic diagnostic apparatuses having excellent portability are known. This portable ultrasonic diagnostic apparatus includes a notebook type in which a lid housing having a display device can be folded against a thin main body housing. An operation unit arrangement is formed on the upper surface of the main body casing, and the operation unit arrangement is covered with a lid casing provided with the display device on the inner surface so that the display device and the operation unit arrangement surface are contained in the two casings. The form is excellent in portability. Further, a fixed handle formed integrally with the main body casing is provided in front of the thin main body casing, and the portability is further improved through the fixed handle.
　一方、操作部配置面には、手前側には、診断時に使用するトラックボールを主体とする第１操作群とその後方に配置される文字入力を可能とするキーボードを主体とする第２操作群が設けられているので、超音波診断の操作に加えて情報処理装置としての操作も可能である。 On the other hand, on the operation unit arrangement surface, on the front side, a first operation group mainly composed of a trackball used at the time of diagnosis and a second operation group mainly composed of a keyboard capable of character input disposed behind the first operation group. Therefore, in addition to the operation of ultrasonic diagnosis, operation as an information processing apparatus is also possible.

　前記従来の携帯型超音波診断装置は、本体筺体の上面に形成される操作部配置面を平坦なフラット面とし、その手前にトラックボールを主体とする第１操作群を配置し、その後方に配置される文字入力を可能とするキーボードを主体とする第２操作群を配置している。すなわち、操作スイッチ類が１つの操作部配置面にコンパクトにまとめられている。しかし、トラックボールは、マウスのように広い操作面を必要としないので、携帯型超音波診断装置に最適な座標指示装置と言える半面、トラックボールの上端が操作部配置から大きく飛び出すという課題がある。また、携帯型超音波診断装置では、調整スイッチとしてロータリーつまみがしばしば作用される。このため、携帯型超音波診断装置では、操作部配置面から大きく飛び出したトラックボールやロータリーつまみが操作部配置面から大きく突出するため、小型化に大きな支障をきたしている。しかも、これらトラックボールやロータリーつまみは、使用頻度の観点から、操作部配置面の手前側に配置される。このため、その後方に配置するキーボードの操作の際に、これらトラックボールやロータリーつまみが邪魔になるため、操作する操作者に手を浮かして入力するなどの無理な操作姿勢を強いていた。 In the conventional portable ultrasonic diagnostic apparatus, the operation unit disposition surface formed on the upper surface of the main body casing is a flat flat surface, the first operation group mainly including a trackball is disposed in front of the operation unit disposition surface, and the rear thereof. A second operation group mainly including a keyboard capable of inputting characters to be arranged is arranged. That is, the operation switches are gathered in a compact manner on one operation unit arrangement surface. However, since a trackball does not require a wide operation surface like a mouse, it can be said that it is an optimal coordinate pointing device for a portable ultrasonic diagnostic apparatus, but there is a problem that the upper end of the trackball protrudes greatly from the operation unit arrangement. . In a portable ultrasonic diagnostic apparatus, a rotary knob is often used as an adjustment switch. For this reason, in the portable ultrasonic diagnostic apparatus, since the trackball and the rotary knob that greatly protrude from the operation unit arrangement surface protrude greatly from the operation unit arrangement surface, the downsizing is greatly hindered. Moreover, these trackballs and rotary knobs are arranged on the front side of the operation unit arrangement surface from the viewpoint of frequency of use. For this reason, these trackballs and rotary knobs obstruct the operation of the keyboard arranged behind them, and therefore, an unreasonable operation posture such as floating the hand to the operating operator and inputting it was forced.
　また、携帯型超音波診断装置では、探触子をコネクタを本体筺体に取り付ける必要があるが、このコネクタが大きいため、本体筺体の薄型化の障害の１つともなっている。 Also, in the portable ultrasonic diagnostic apparatus, it is necessary to attach a probe to the main body housing. However, since this connector is large, it is one of the obstacles to thinning the main body housing.
　そこで、本発明の目的は、操作性に優れたコンパクトな携帯型超音波診断装置を提供することにある。 Therefore, an object of the present invention is to provide a compact portable ultrasonic diagnostic apparatus excellent in operability.
　前記目的を達成するために、本発明では、上面に操作部配置面を備えた本体筺体と、表示装置を備えた蓋筺体と、前記本体筺体の後部と前記蓋筺体の一端とを連結し、前記操作部配置面と前記表示装置とを隠蔽するように折りたたみ可能とする連結部とを備えた携帯型超音波診断装置において、前記操作部配置面には、トラックボールを備えた第１操作群とキーボードを含む第２操作群とを有し、前記第１操作群は前記第２操作群よりも低い位置に配置されるようにする。 In order to achieve the above object, in the present invention, a main body housing having an operation unit arrangement surface on the upper surface, a lid housing including a display device, a rear portion of the main body housing, and one end of the lid housing are connected, In the portable ultrasonic diagnostic apparatus including a connection unit that can be folded so as to hide the operation unit arrangement surface and the display device, the operation unit arrangement surface includes a first operation group including a trackball. And a second operation group including a keyboard, and the first operation group is arranged at a position lower than the second operation group.
　この発明によれば、後部に配置されている第２操作群の操作の際に前部に配置されている第１操作群が邪魔になるのを軽減することができる。 According to the present invention, it is possible to reduce the obstruction of the first operation group arranged in the front part during the operation of the second operation group arranged in the rear part.

　先ず、図１を参照して、この実施例に係る携帯型超音波診断装置の概略構造を説明する。図１において、符号１で総括的に示す携帯型超音波診断装置は、上面に操作部配置面１０１を備えた薄型の本体筺体１００と、薄型の表示装置（モニタ装置）２０１を備えた蓋筺体２００と、本体筺体１００の後部と蓋筺体２００の一端を連結し、操作部配置面１０１と表示装置２０１とを隠蔽するように折りたたみ可能とする連結部１０とを備えている。 First, the schematic structure of a portable ultrasonic diagnostic apparatus according to this embodiment will be described with reference to FIG. In FIG. 1, a portable ultrasonic diagnostic apparatus generally indicated by reference numeral 1 includes a thin main body casing 100 having an operation unit arrangement surface 101 on an upper surface and a lid casing including a thin display device (monitor device) 201. 200, and a connecting portion 10 that connects the rear portion of the main body housing 100 and one end of the lid housing 200 and is foldable so as to hide the operation portion arrangement surface 101 and the display device 201.
　本体筺体１００は、樹脂材料で形成される下ケース１１１と、樹脂材料で形成される上ケース１１２とで、内部実装品を包含することで、薄い扁平な形態としている。この実施例では、携帯性を良好にするために、本体筺体１００の前部を前方に延長して形成し、その延長した部分に開口部１１３を形成することで握り部１１４を構成したハンドル１１５を形成している。もちろん、このハンドル１１５は本体筺体１００と一体形成することに限定されるものではなく、本体筐体１００に折りたたみ可能、あるいは、スライド収納可能とする構造でも良い。また、このハンドル１１５を設けることに限定されるものではない。 The main body casing 100 includes a lower case 111 formed of a resin material and an upper case 112 formed of a resin material, and includes an internal mounting product, thereby forming a thin flat shape. In this embodiment, in order to improve portability, the front portion of the main body casing 100 is formed to extend forward, and the handle 115 is formed by forming the opening portion 113 in the extended portion. Is forming. Of course, the handle 115 is not limited to being integrally formed with the main body casing 100, and may be configured to be foldable or slidable into the main body casing 100. Further, the present invention is not limited to the provision of the handle 115.
　一方、蓋筺体２００は、液晶の表示装置２０１を内蔵させた薄い板状の形状としている。この蓋筺体２００は、本体筺体１００の上面に形成される操作部配置面１０１を覆う大きさを備えており、その一端を本体筺体１００の後部の両側に設けられる一対の連結部１０を介して折りたたみ可能に連結される。 On the other hand, the lid housing 200 has a thin plate shape in which a liquid crystal display device 201 is incorporated. The lid housing 200 has a size that covers the operation portion arrangement surface 101 formed on the upper surface of the main body housing 100, and one end of the lid housing 200 via a pair of connecting portions 10 provided on both sides of the rear portion of the main body housing 100. It is connected in a foldable manner.
　この構造によれば、蓋筺体２００を折りたたむことで、操作部配置面１０１と表示装置２０１を２つの筺体（１００、２００）内に隠蔽することができるので、携帯性が良好である。また、この折りたたんだ形態では、ハンドル１１５が露出しているので、このハンドル１１５の握り部１１４を確り保持して搬送することができる。一方、蓋筺体２００を開放した状態では、図１に示すように、操作部配置面１０１の後方に表示装置２０１が立ち姿勢で保持されるので、表示装置２０１に表示される情報を確認しながら操作することができる。 According to this structure, by folding the lid housing 200, the operation unit arrangement surface 101 and the display device 201 can be concealed in the two housings (100, 200), so that portability is good. Further, in this folded form, the handle 115 is exposed, so that the grip portion 114 of the handle 115 can be securely held and transported. On the other hand, in the state where the lid housing 200 is opened, the display device 201 is held in a standing posture behind the operation unit arrangement surface 101 as shown in FIG. 1, while confirming information displayed on the display device 201. Can be operated.
　そして、この携帯型超音波診断装置１の特徴の１つは、第１操作群２３０は第２操作群２６０よりも低い位置に配置されていることである。その一例としては、操作部配置面１０１を前後に段差をつけて形成し、前部の一段低い前部配置面１０２にトラックボール２３１を備えた第１操作群２３０を配置し、後部の一段高い後部配置面１０３に文字入力可能なキーボード２６１を含む第２操作群２６０を配置した点にある。 And one of the features of this portable ultrasonic diagnostic apparatus 1 is that the first operation group 230 is arranged at a lower position than the second operation group 260. As an example, the operation portion arrangement surface 101 is formed with a step in the front and rear, the first operation group 230 including the trackball 231 is arranged on the front portion arrangement surface 102 which is one step lower in the front portion, and the rear portion is one step higher. The second operation group 260 including the keyboard 261 capable of inputting characters is arranged on the rear arrangement surface 103.
　具体的には、前部配置面１０２と後部配置面１０３との間に形成される段差部１０４を介して、操作部配置面１０１を前後に分割し、前部の低い前部配置面１０２に上方に突出するトラックボール２３１やロータリスイッチ２３２を備えた第１操作群２３０を配置し、後部の一段高い後部配置面１０３にキーボード２６１を備えた第２操作群２６０を配置している。 Specifically, the operation unit arrangement surface 101 is divided into front and rear via a stepped portion 104 formed between the front arrangement surface 102 and the rear arrangement surface 103 to form a lower front arrangement surface 102. A first operation group 230 having a track ball 231 and a rotary switch 232 protruding upward is arranged, and a second operation group 260 having a keyboard 261 is arranged on the rear arrangement surface 103 which is one step higher in the rear.
　このように第１操作群２３０は第２操作群２６０よりも低い位置に配置することで、キーボード等の第２操作群の操作を実行する際に、トラックボール２３１等の第１操作群２３０の操作部材を誤って触れてしまうことによる誤操作を防止できる。このとき第１操作群２３０の操作部材の内、最も高さを有する操作部材（たとえば、トラックボール２３１等）の高さよりも段差部の高さを高く構成することで、さらに効果的に誤操作を防止できる。 As described above, the first operation group 230 is arranged at a position lower than the second operation group 260, so that when the operation of the second operation group such as a keyboard is executed, the first operation group 230 such as the trackball 231 is performed. It is possible to prevent erroneous operation caused by touching the operation member by mistake. At this time, by configuring the height of the stepped portion to be higher than the height of the operation member having the highest height (for example, the trackball 231) among the operation members of the first operation group 230, the erroneous operation can be performed more effectively. Can be prevented.
　また、この携帯型超音波診断装置１の特徴の他の１つは、前記２段の操作部配置面１０１を実現するために、第１操作群２３０の下方の本体筺体１００内に第１操作群基板２０を配置し、第２操作群２６０の下方の本体筺体１００内には、制御部（図２参照）を含むメイン基板３０と、このメイン基板３０の後方に配置されるバッテリ部４０と、このバッテリ部４０とメイン基板３０の片側に配置される探触子コネクタ部５０と、メイン基板３０とバッテリ部４０の上方に配置される第２操作群基板６０とを備えるようにする。ここで、この実施例では、第２操作群基板６０を、メイン基板３０の上方に配置されるキーボード基板６１と、このキーボード基板６１の両側に配置される第１サブ基板６２と第２サブ基板６３と、バッテリ部４０の上方に配置される第３サブ基板６４とで構成する。そして、この実施例では、凹凸の少ないスイッチ類を第１サブ基板６２と第２サブ基板６３と第３サブ基板６４に配置し、これらをキーボード基板６１の厚さ調整部材とすることで、後部配置面１０３を実装効率が良好で、しかも、フラットな配置面としている。 Another feature of the portable ultrasonic diagnostic apparatus 1 is that the first operation is performed in the main body casing 100 below the first operation group 230 in order to realize the two-stage operation unit arrangement surface 101. The main board 30 including the control unit (see FIG. 2) and the battery unit 40 disposed behind the main board 30 are disposed in the main body housing 100 below the second operation group 260. The battery connector 40 and the probe connector unit 50 disposed on one side of the main substrate 30 and the second operation group substrate 60 disposed above the main substrate 30 and the battery unit 40 are provided. Here, in this embodiment, the second operation group substrate 60 includes a keyboard substrate 61 disposed above the main substrate 30, and a first sub substrate 62 and a second sub substrate disposed on both sides of the keyboard substrate 61. 63 and the third sub-board 64 disposed above the battery unit 40. In this embodiment, switches having less unevenness are arranged on the first sub-board 62, the second sub-board 63, and the third sub-board 64, and these are used as the thickness adjusting member of the keyboard board 61, so that the rear part The placement surface 103 has a good mounting efficiency and is a flat placement surface.
　また、この実施例では、第２操作群２６０の下方の本体筺体１００内に探触子コネクタ部５０を配置することで、探触子の操作性を維持しつつ、操作部配置面１０１の２段構造に貢献させている。したがって、この探触子コネクタ部を前記の通り配置することによって、携帯型超音波診断装置１の小型化に大きく貢献できる。 Further, in this embodiment, the probe connector portion 50 is arranged in the main body casing 100 below the second operation group 260, so that the operability of the probe is maintained and 2 of the operation portion arrangement surface 101 is maintained. It contributes to the step structure. Therefore, disposing the probe connector portion as described above can greatly contribute to the miniaturization of the portable ultrasonic diagnostic apparatus 1.
　この実施例では、厚みのある後部配置面１０３の片側に配置することで、前記課題を解決している。しかも、この側面後方は、搬送性においても、操作性の面からも有効である。即ち、探触子を装着した状態で搬送する場合、ハンドルを持つことから、本体筺体１００の背面に探触子コネクタ部５０を設けると、この探触子コネクタ部５０に取り付けるコード接続部５１ａ（図４参照）が床面やテーブル面に当たりやすい課題がある。また、探触子コネクタ部５０が本体筺体１００の側面の前よりにあると、探触子コネクタ部５０から引き出されるコードが操作者に邪魔になる課題もある。この実施例のように、側面後方に探触子コネクタ部５０を設けることで、前記課題を解決できるとともに、前部配置面１０２が配置される本体筺体１００の前部の厚さを薄くすることができる。 In this embodiment, the above-described problem is solved by disposing on one side of the thick rear disposition surface 103. Moreover, this rear side surface is effective in terms of transportability and operability. That is, when transporting with the probe mounted, since it has a handle, if the probe connector portion 50 is provided on the back surface of the main body housing 100, the cord connection portion 51a ( (See FIG. 4) is likely to hit the floor or table surface. Further, when the probe connector unit 50 is located in front of the side surface of the main body housing 100, there is a problem that a cord drawn from the probe connector unit 50 becomes an obstacle to the operator. As in this embodiment, by providing the probe connector portion 50 on the rear side of the side surface, the above-mentioned problems can be solved and the thickness of the front portion of the main body housing 100 where the front portion arrangement surface 102 is arranged is reduced. Can do.
　また、この実施例では、バッテリ部４０を本体筺体１００の後端部に設けている。これにより、バッテリ部４０の装着を本体筺体１００の背面から行うことができる。しかも、この実施例では、バッテリ部４０の両側に一対の連結部１０を配置しているので、この連結部１０による蓋筺体２００の折りたたみ構造に支障をきたすことがない。 In this embodiment, the battery unit 40 is provided at the rear end of the main body casing 100. Thereby, mounting of the battery part 40 can be performed from the back surface of the main body housing 100. In addition, in this embodiment, since the pair of connecting portions 10 are disposed on both sides of the battery portion 40, the folding structure of the lid housing 200 by the connecting portions 10 is not hindered.
　また、この携帯型超音波診断装置１の特徴の他の１つは、操作者の手若しくは手首を置くためのパームレスト１２０を設けた点にある。具体的には、この実施例では、前部配置面１０２の第１パームレスト１２１としてハンドル１１５を割り当てる。また、後部配置面１０３の第２パームレスト１２２として段差部１０４を割り当てる。特に、第２パームレスト１２２として、操作スイッチするが配置しづらい段差部１０４近傍に平滑面１２２ａを形成し、この平滑面１２２ａを第２パームレスト１２２として利用することができる。前部配置面１０２と後部配置面１０３との間に形成される段差部は、ここではカーブの傾斜面としている。このように傾斜面を、凹状にカーブさせることで手首をフィットさせることができ、使い勝手が向上する。ここでは傾斜面を滑らかなカーブの傾斜面としたが、必ずしもこれに限るものではない。 Further, another feature of the portable ultrasonic diagnostic apparatus 1 is that a palm rest 120 for placing an operator's hand or wrist is provided. Specifically, in this embodiment, a handle 115 is assigned as the first palm rest 121 of the front arrangement surface 102. Further, the step 104 is assigned as the second palm rest 122 of the rear arrangement surface 103. In particular, as the second palm rest 122, a smooth surface 122a can be formed in the vicinity of the stepped portion 104 that is difficult to place although it is operated, and this smooth surface 122a can be used as the second palm rest 122. The step portion formed between the front arrangement surface 102 and the rear arrangement surface 103 is a curved inclined surface here. In this way, the wrist can be fitted by curving the inclined surface in a concave shape, which improves usability. Here, although the inclined surface is a smooth curved inclined surface, the present invention is not limited to this.

That is, when the inclined surface 105 is formed in the stepped portion 104, the inclined surface 105 becomes an inclined surface facing the operator. Therefore, by providing switches on the inclined surface 105, the operability and visibility of these switches can be improved. Here, when the switches are provided on the inclined surface 105, the planar inclined surface improves usability.
　この携帯型超音波診断装置１の特徴の他の１つは、蓋筺体２００に回転軸Ｐを中心とする旋回機構部２１０を設けた点にある。即ち、携帯型超音波診断装置１では、表示装置２０１に表示される情報は操作者のみが確認するのではなく、その内容を患者にも見せるケースが頻繁に起こる。この場合、蓋筺体２００が旋回可能であれば、対応することができる。そこで、この実施例では、蓋筺体２００を、連結部１０で連結される連結筺体２０２と、表示装置２０１を備えた表示筺体２０３と、この連結筺体２０２と表示筺体２０３とを旋回可能に連結する旋回機構部２１０とで構成する。旋回機構部２１０は表示筺体２０３を中心位置で回転可能に連結する旋回軸２１１と、旋回を所定の位置で固定するロックスイッチ２１２で構成する。この実施例ではロックスイッチ２１２を、連結筺体２０２と表示筺体２０３の接触面に図示しないバネなどを介して出没可能に設けた突起で構成する。これにより、連結筺体２０２と表示筺体２０３の接触面が一致した状態で固定することができる。 Another feature of the portable ultrasonic diagnostic apparatus 1 is that a lid mechanism 200 is provided with a turning mechanism unit 210 centering on the rotation axis P. That is, in the portable ultrasonic diagnostic apparatus 1, the information displayed on the display device 201 is not always confirmed only by the operator, but frequently the contents are shown to the patient. In this case, if the lid housing 200 can be turned, it can be dealt with. Therefore, in this embodiment, the lid housing 200 is connected to the connecting housing 202 connected by the connecting portion 10, the display housing 203 including the display device 201, and the connecting housing 202 and the display housing 203 so as to be turnable.

The echo is amplified, phased, and detected, and the output signal is input to the DSC 53. These ultrasonic probes 51 include a cord having a predetermined length, and are provided corresponding to the ultrasonic probe 51 via a cord connecting portion 51a (see FIG. 4) provided at the tip of the cord. Connected to the probe connector 50.
　前記ＤＳＣ５３は、入力した信号をデジタル信号に変換し、超音波ビームを１本ずつ送受信の繰返し毎にメモリへ書き込み、また記憶内容を表示装置２０３の走査に同期して読み出す。メモリ装置５４を構成する共通用グラフィックメモリは、ＤＳＣ５３を介して表示装置２０３へ表示される超音波画像へ重畳して表示する付加情報、例えば、超音波画像のスケール，被検者への超音波探触子５１の当接位置を示すボディマーク，距離計測情報のように被検者に不安感をもたらさない情報を表示するためのグラフィックメモリである。また、メモリ装置５４の操作用グラフィックメモリは、表示装置２０３の超音波画像へ操作者が診断に必要とする付加情報のみ、例えば病名や被検者のＩＤ情報のような文字情報や病変部を示す矢印等の記号情報のみを重畳して表示するグラフィックメモリである。 The DSC 53 converts the input signal into a digital signal, writes the ultrasonic beam one by one into the memory every time transmission / reception is repeated, and reads out the stored contents in synchronization with the scanning of the display device 203. The common graphic memory constituting the memory device 54 includes additional information to be displayed superimposed on the ultrasonic image displayed on the display device 203 via the DSC 53, for example, the scale of the ultrasonic image, the ultrasonic wave to the subject. This is a graphic memory for displaying information that does not cause anxiety to the subject such as a body mark indicating the contact position of the probe 51 and distance measurement information. In addition, the operation graphic memory of the memory device 54 stores only additional information necessary for diagnosis by the operator in the ultrasonic image of the display device 203, for example, character information such as a disease name and a subject's ID information and a lesion part. It is a graphic memory that superimposes and displays only symbol information such as arrows.
　この超音波診断装置１によれば、入力装置５５を操作して、超音波走査モードや計測付加情報表示を設定し、超音波探触子５１を被検者の検査部位へ当接して検査を開始する。超音波探触子５１から被検者の体内へ送波された超音波は、体内の臓器の音響インピーダンスの異なる境界で反射されて探触子で受信される。受信されたエコーは超音波送受信装置５２で増幅，整相，検波され、超音波走査線１本分の信号としてＤＳＣ５３へ入力され、Ｄ／Ａ変換されてメモリへ書き込まれる。このメモリへの書き込みは、超音波送受信の方向を変えての繰返し送受信毎に行われる。 According to this ultrasonic diagnostic apparatus 1, the input device 55 is operated to set the ultrasonic scanning mode and the measurement additional information display, and the ultrasonic probe 51 is brought into contact with the inspection site of the subject to perform the inspection.

In synchronization with the reading of the image data from the DSC 53, the control unit 31 reads data from both the common graphic memory and the operator graphic memory. In this embodiment, when the display screen of the display device 201 is shown to the subject, the contents of the operator graphic memory can be hidden. This switching of the display screen can be operated via the second operation group 260.
　次に、図１と図３を介して、本体筺体１００内に配置される各装置のレイアウトを更に説明する。ここで、図３の（ａ）図はトラックボールを含む縦断面図であり、（ｂ）図はメイン基板を含む横断面図である。図１及び図３において、下ケース１１１の内部に図示しない板状の取付シャーシを形成し、この取付シャーシの前部に第１操作群基板２０、その後方にメイン基板３０、その後方にバッテリ部４０を配置し、更に図３（ｂ）図に示すように、メイン基板３０の片側に探触子コネクタ部５０を配置することで第１階層を構成する。第１操作群基板２０は、板状の基板の上にトラックボール２３１や複数のロータリスイッチ２３２などが配置されるものである。したがって、この第１操作群基板２０を包含する本体筺体１００の前部は、その厚さ（高さ寸法）を小さくすることができる。 Next, the layout of each device arranged in the main body casing 100 will be further described with reference to FIGS. 1 and 3. Here, FIG. 3A is a longitudinal sectional view including a trackball, and FIG. 3B is a transverse sectional view including a main substrate. 1 and 3, a plate-shaped mounting chassis (not shown) is formed inside the lower case 111, the first operation group board 20 at the front of the mounting chassis, the main board 30 at the rear, and the battery section at the rear. 40, and as shown in FIG. 3B, the probe connector 50 is arranged on one side of the main board 30 to constitute the first layer. The first operation group substrate 20 has a trackball 231 and a plurality of rotary switches 232 arranged on a plate-like substrate. Therefore, the thickness (height dimension) of the front portion of the main body casing 100 including the first operation group substrate 20 can be reduced.
　一方、制御部３１を含むメイン基板３０は、制御部３１の放熱装置などで厚みのある制御基板である。また、バッテリ部４０はメイン基板３０に合わせて高さ寸法が設定され、充電量の不足分は本体筺体１００の後方に張り出させることで確保している。 On the other hand, the main board 30 including the control unit 31 is a thick control board such as a heat dissipation device of the control unit 31. Further, the battery unit 40 has a height dimension set in accordance with the main board 30, and an insufficient amount of charge is secured by projecting behind the main body casing 100.
　また、探触子コネクタ部５０は、第１階層の中では、最も厚み（高さ寸法）のある装置である。この実施例では、この最も厚みのある探触子コネクタ部５０を厚さのある本体筺体１００の後部に設けることで、本体筺体１００の前部の厚さ（高さ寸法）を小さくしている。 Further, the probe connector unit 50 is a device having the largest thickness (height dimension) in the first layer. In this embodiment, the thickness (height dimension) of the front portion of the main body casing 100 is reduced by providing the thickest probe connector portion 50 at the rear of the main body casing 100 having a thickness. .
　図３（ａ）図に示すように、メイン基板３０とバッテリ部４０の上部にはキーボード基板６１と第３サブ基板６４が前後に並べて配置される。一方、図３（ｂ）に示すように、キーボード基板６１の両側には第１サブ基板６２と第２サブ基板６３を分けて配置している。即ち、本体筺体１００の後部は、第１階層の上に第２階層の装置を積層する構造を採用している。 As shown in FIG. 3A, a keyboard substrate 61 and a third sub-substrate 64 are arranged side by side on the top of the main substrate 30 and the battery unit 40. On the other hand, as shown in FIG. 3B, the first sub board 62 and the second sub board 63 are separately arranged on both sides of the keyboard board 61. In other words, the rear portion of the main body housing 100 employs a structure in which the devices in the second layer are stacked on the first layer.
　前記したように、この実施例では、本体筺体１００の前部には薄い第１操作群基板２０のみを配置し、本体筺体１００の後部には積層構造を採用している。この構造により、段差部１０４を介して、低い前部配置面１０２と、高い後部配置面１０３とで構成される前後２段の操作部配置面１０１を実現している。 As described above, in this embodiment, only the thin first operation group substrate 20 is disposed in the front portion of the main body casing 100, and a laminated structure is adopted in the rear portion of the main body casing 100. With this structure, a front and rear two-stage operation unit arrangement surface 101 constituted by a low front arrangement surface 102 and a high rear arrangement surface 103 is realized via the stepped portion 104.
　また、この実施例では、蓋筺体２００において表示装置２０１が前方に傾斜した姿勢で収納される構造としている。即ち、操作部配置面がフラットな従来例では、蓋筺体を折りたたんだ姿勢では、蓋筺体に配置される表示装置２０１は操作部配置面と平行な姿勢となるのが一般的である。しかし、この実施例では、操作部配置面１０１を２段階形状としているので、図３（ｂ）図のように、蓋筺体を折りたたんだ姿勢では、表示装置２０１を前傾斜となるようにしている。この構造によれば、蓋筺体２００を折りたたんだ姿勢では、蓋筺体２００も前傾斜となって、携帯型超音波診断装置１の前部が先細りの形状となるので、小型化の印象の強い外観形状とすることができる。表示装置を備えた蓋筺体は、前部配置面と後部配置面との間に形成される段差部に合うように形成されている。
具体的には、当該段差部に併せて表示筺体の外枠部材に段差部を形成させると良い。 In this embodiment, the display device 201 is stored in the lid housing 200 in a posture inclined forward. That is, in the conventional example in which the operation unit arrangement surface is flat, the display device 201 arranged on the cover case is generally in a posture parallel to the operation unit arrangement surface in a posture in which the cover case is folded. However, in this embodiment, since the operation portion arrangement surface 101 has a two-stage shape, the display device 201 is inclined forward when the lid housing is folded as shown in FIG. . According to this structure, in the posture in which the lid housing 200 is folded, the lid housing 200 is also inclined forward, and the front portion of the portable ultrasonic diagnostic apparatus 1 has a tapered shape. It can be a shape. The lid housing provided with the display device is formed so as to fit a step portion formed between the front arrangement surface and the rear arrangement surface.
Specifically, the stepped portion may be formed on the outer frame member of the display casing in combination with the stepped portion.
　一方、表示装置２０１を前傾斜とすることで、後部配置面１０３と表示装置２０１との間に空間を形成することができるので、この空間を利用して後部配置面１０３に配置される第２操作群２６０のスイッチ類を突出させることができるので、これらの操作性を向上させることができる。 On the other hand, since the display device 201 is inclined forward, a space can be formed between the rear arrangement surface 103 and the display device 201. Therefore, the second arrangement on the rear arrangement surface 103 is performed using this space. Since the switches of the operation group 260 can be protruded, their operability can be improved.
　また、この実施例では、操作部配置面１０１を２段階形状としているので、携帯型超音波診断装置１の前部を先細りの形状としても、前部配置面１０２と表示装置１０１の間には大きな空間を形成することができる。この大きな空間によれば、大きなトラックボール２３１や突出量の大きいロータリスイッチ２３２を配置することができるから、装置の小型化と操作性を向上することができる。 Further, in this embodiment, since the operation portion arrangement surface 101 has a two-stage shape, even if the front portion of the portable ultrasonic diagnostic apparatus 1 is tapered, there is no gap between the front portion arrangement surface 102 and the display device 101. A large space can be formed. According to this large space, the large trackball 231 and the rotary switch 232 having a large protruding amount can be disposed, so that the apparatus can be miniaturized and the operability can be improved.
　次に、図４と図５を参照して、携帯型超音波診断装置１の外観形状を説明する。ここで、図５の（ａ）図は蓋筺体を開いた状他の右側面図であり、（ｂ）図は蓋筺体を折りたたんだ状態の左側面図である。 Next, with reference to FIG. 4 and FIG. 5, the external shape of the portable ultrasonic diagnostic apparatus 1 will be described.

Since the inclined surface 105 is inclined to the operator side from the front arrangement surface 102 and the rear arrangement surface 103 having a horizontal surface, the operation keys arranged on the inclined surface 105 are highly visible and easy to operate. Are better. In this embodiment, a fifth switch group 237 is disposed on the inclined surface 105.
　次に、キーボード２６１を主体とした第２操作群２６０を説明する。この第２操作群２６０は、後部配置面１０３の中央に配置されるキーボード２６１と、このキーボード２６１の両側に配置される第１後部スイッチ群２６２と第２後部スイッチ群２６３と、キーボード２６１の後方に配置される第３後部スイッチ群２６４とを含んで構成される。ここで、キーボード２６１がキーボード基板６１、第１後部スイッチ群２６２が第１サブ基板６２、第２後部スイッチ群２６３が第２サブ基板６３、第３後部スイッチ群２６４が第３サブ基板６４に対応する。 Next, the second operation group 260 mainly composed of the keyboard 261 will be described. The second operation group 260 includes a keyboard 261 arranged at the center of the rear arrangement surface 103, a first rear switch group 262 and a second rear switch group 263 arranged on both sides of the keyboard 261, and a rear side of the keyboard 261.

The third rear switch group 264 includes switches corresponding to the switches displayed on the display device 102 and screen adjustment switches.
　ここで、この実施例では、キーボード２６１の前部に平滑面１２２ａを形成し、この平滑面１２２ａを傾斜面１０５に連続することで第２パームレスト１２２を形成している。つまり、この第２パームレスト１２２に手首を支持することで、第２操作群２６０の入力操作を向上することができる。一方、第１操作群２３０は、その前部に形成されるハンドル１１５を第１パームレスト１２１として活用することができるので、第１操作群２３０の入力操作を向上することができる。 Here, in this embodiment, a smooth surface 122 a is formed in the front portion of the keyboard 261, and the second palm rest 122 is formed by continuing the smooth surface 122 a to the inclined surface 105. That is, by supporting the wrist on the second palm rest 122, the input operation of the second operation group 260 can be improved. On the other hand, the first operation group 230 can improve the input operation of the first operation group 230 because the handle 115 formed at the front thereof can be used as the first palm rest 121.
　図５（ａ）図において、この実施例では、第１操作群２３０を構成するトラックボール２３１やロータリスイッチ２３２は、前部配置面１０２から上方に突出することとなるが、この突出する部分は、前部配置面１０２と後部配置面１０３の段差寸法Hの範囲内に収めることができる。 In FIG. 5A, in this embodiment, the trackball 231 and the rotary switch 232 constituting the first operation group 230 protrude upward from the front placement surface 102. Thus, the front arrangement surface 102 and the rear arrangement surface 103 can be accommodated within the range of the step size H.
　また、図４や図３(ａ)に示すように、第１後部スイッチ群２６２の彩度別ゲインスライドスイッチは、スライドスイッチの突出量を大きくすると操作性が向上する。この実施例では前記突出量を確保するため、彩度別ゲインスライドスイッチを後部配置面１０３より一段低くするとともに、表示装置２０１を前方に傾斜させることで確保している。 Also, as shown in FIG. 4 and FIG. 3A, the operability of the gain slide switch classified by saturation of the first rear switch group 262 is improved by increasing the protruding amount of the slide switch. In this embodiment, in order to secure the projection amount, the saturation-specific gain slide switch is made one step lower than the rear arrangement surface 103 and the display device 201 is tilted forward.
　また、図４及び図５に示すように、この実施例では、後部配置面１０３の片側となる右側面後方に探触子コネクタ部５０を設けている。この探触子コネクタ部５０にコード接続部５１ａを取り付けることで、超音波探触子５１を接続することができる。コード接続部５１ａは棒状の本体を備えており、通常、コードが邪魔にならないように、本体の長手方向の一端側にコードが取り付けられている。この実施例に係る探触子コネクタ部５０の配置は、本体筺体１００の側面後方に配置されているので、本体筺体１００の前部の空間を利用してコード処理することができる。しかも、既に述べたように、探触子コネクタ部５０の配置は、操作部配置面１０１の２段構造に大きく貢献している。 Further, as shown in FIGS. 4 and 5, in this embodiment, the probe connector portion 50 is provided behind the right side surface, which is one side of the rear portion arrangement surface 103. The ultrasonic probe 51 can be connected by attaching the cord connecting portion 51 a to the probe connector portion 50. The cord connecting portion 51a has a rod-like main body, and usually the cord is attached to one end side in the longitudinal direction of the main body so that the cord does not get in the way. Since the arrangement of the probe connector portion 50 according to this embodiment is arranged behind the side surface of the main body housing 100, code processing can be performed using the space in the front portion of the main body housing 100. Moreover, as already described, the arrangement of the probe connector part 50 greatly contributes to the two-stage structure of the operation part arrangement surface 101.
　また、この実施例では、本体筺体１００の両側面に通風口１３０を設けている。これにより、本体筺体１００の内部に配置される図示しない送風装置を介して。一方の片側から空気を取り込んで、内部装置を冷却した後、他の側面から排気することができる。 Further, in this embodiment, the vent holes 130 are provided on both side surfaces of the main body casing 100. Thereby, via the air blower which is arrange | positioned inside the main body housing | casing 100. After taking air from one side and cooling the internal device, it can be exhausted from the other side.
　次に、図６を参照しながら、２段構造の操作部配置面１０１の操作性について説明する。ここで、図６の（ａ）図は第１操作群２３０の操作姿勢を示し、図６の（ｂ）図は第２操作群２６０の操作姿勢を示している。 Next, the operability of the operation unit arrangement surface 101 having a two-stage structure will be described with reference to FIG. Here, FIG. 6A shows the operation posture of the first operation group 230, and FIG. 6B shows the operation posture of the second operation group 260.
　図６において、この実施例ではパームレスト１２０を、ハンドル１１５を活用した第１パームレスト１２１と、段差部１０４を活用した第２パームレスト１２２で構成している。（ａ）図に示すように、第１操作群２３０を操作する場合は第１パームレスト１２１に手首を支持して第１操作群２３０を操作することができる。特に、携帯型超音波診断装置１においては、片手で超音波探触子５１を患者にあてがい、他の片手はトラックボール２３１を操作し、目線は表示装置を見ることが頻繁に行われる。この実施例では、大きなハンドル１１５全体を第１パームレスト１２１として活用できるので、ブラインドタッチに適している。 In FIG. 6, in this embodiment, the palm rest 120 includes a first palm rest 121 using the handle 115 and a second palm rest 122 using the stepped portion 104. (A) As shown to a figure, when operating the 1st operation group 230, a wrist can be supported by the 1st palm rest 121, and the 1st operation group 230 can be operated. In particular, in the portable ultrasonic diagnostic apparatus 1, it is frequently performed that the ultrasonic probe 51 is applied to a patient with one hand, the other hand operates the trackball 231, and the line of sight looks at the display device. In this embodiment, since the entire large handle 115 can be used as the first palm rest 121, it is suitable for blind touch.
　一方、（ｂ）図に示すように、第２操作群２６０を操作する姿勢ではキーボード２６１の前部に形成される第２パームレスト１２２に手首を支持して入力操作することができる。特に、第２操作群２６０は、携帯型超音波診断装置１を情報処理装置として利用するときに使用される。このため、使用者は、両手首をこの第２パームレスト１２２に支持して、画面を見ながら操作することができる。 On the other hand, as shown in FIG. 5B, in a posture in which the second operation group 260 is operated, an input operation can be performed with the wrist supported by the second palm rest 122 formed at the front portion of the keyboard 261. In particular, the second operation group 260 is used when the portable ultrasonic diagnostic apparatus 1 is used as an information processing apparatus. For this reason, the user can operate while supporting both wrists on the second palm rest 122 and viewing the screen.
　次に、図７と図８を参照して、第２の実施例に係る携帯型超音波診断装置１ａを説明する。ここで、図８が携帯型超音波診断装置の部品展開図である。図９携帯型超音波診断装置の内部実装を示す断面図である。なお、同様な部位や矢印は同一符号をもって示し、重複した説明を省略する。 Next, a portable ultrasonic diagnostic apparatus 1a according to the second embodiment will be described with reference to FIGS. Here, FIG. 8 is a component development view of the portable ultrasonic diagnostic apparatus. 9 is a cross-sectional view showing the internal mounting of the portable ultrasonic diagnostic apparatus. In addition, the same site | part and arrow are shown with the same code | symbol, and the overlapping description is abbreviate | omitted.
　この第２実施例に係る携帯型超音波診断装置１ａは、第２探触子コネクタ部５０ａを設けることで、本体筺体１００の一方の側面に２個の探触子コネクタ部（５０、５０ａ）を前後に並べて設けた点に特徴がある。 The portable ultrasonic diagnostic apparatus 1a according to the second embodiment has two probe connector portions (50, 50a) on one side surface of the main body casing 100 by providing the second probe connector portion 50a. It is characterized by the fact that the front and back are arranged side by side.
　即ち、超音波診断では、種類の異なる図示しない超音波探触子５１を使うことがある。この場合、探触子コネクタ部５０が１個しかないと、コード接続部５１ａを一々取り換えなければならない。そこで、複数の探触子コネクタ部が欲しいとの要望がある。この実施例は、前記要望を備えたものである。この要望に対して、後部配置面１０３の両側となる本体筺体１００の両側面後部に探触子コネクタ部５０を設けることで、第１実施例と同様な作用効果で対応することができる。 That is, in the ultrasonic diagnosis, an ultrasonic probe 51 (not shown) of a different type may be used. In this case, if there is only one probe connector portion 50, the cord connecting portions 51a must be replaced one by one. Therefore, there is a demand for a plurality of probe connector portions. This embodiment has the above-mentioned demand. In response to this demand, by providing the probe connector portions 50 at the rear portions of both side surfaces of the main body casing 100 which are both sides of the rear portion arrangement surface 103, it is possible to cope with the same effects as the first embodiment.
　しかし、超音波診断では、ベッドに横になる患者の片側に携帯型超音波診断装置１をおいて診断するため、携帯型超音波診断装置１の両側から超音波探触子５１のコードを引き出すと、患者の外側のコードが携帯型超音波診断装置１の操作の邪魔になる課題がある。 However, in the ultrasonic diagnosis, since the portable ultrasonic diagnostic apparatus 1 is diagnosed by placing the portable ultrasonic diagnostic apparatus 1 on one side of the patient lying on the bed, the code of the ultrasonic probe 51 is pulled out from both sides of the portable ultrasonic diagnostic apparatus 1. Then, there is a problem that the code outside the patient obstructs the operation of the portable ultrasonic diagnostic apparatus 1.
　そこで、この実施例では、本体筺体１００の一方の側面に探触子コネクタ部５０を前後に並べる配置構成を採用している。しかし、前記第１実施例でも説明したように、探触子コネクタ部５０は厚みのある装置のため、この探触子コネクタ部５０と第２探触子コネクタ部５０ａを前後に並べると、第２探触子コネクタ部５０ａを薄い本体筐体１００の前部が厚くなってしまう課題がある。 Therefore, in this embodiment, an arrangement configuration is adopted in which the probe connector part 50 is arranged on one side of the main body casing 100 in the front-rear direction. However, as described in the first embodiment, since the probe connector portion 50 is a thick device, if the probe connector portion 50 and the second probe connector portion 50a are arranged in the front and rear directions, There is a problem that the front portion of the thin main body casing 100 is thicker than the two probe connector portion 50a.
　そこで、この第２実施例に係る携帯型超音波診断装置１ａでは、後部配置面１０３の片側を前方に高さを維持したまま伸ばした形状とし、この延ばした延長部１０６内に第２探触子コネクタ部５０ａを配置する。この場合、この延長部１０６は一方の片側だけでも良いが、この実施例では、意匠性を考慮して両側に延長部１０６を形成している。更に、延長部１０６はそのボリューム感を軽減するために、積層構造とすることなく前方に傾斜させている。 Therefore, in the portable ultrasonic diagnostic apparatus 1a according to the second embodiment, one side of the rear arrangement surface 103 is formed to be extended with the height maintained at the front, and the second probe is provided in the extended extension 106. The sub connector part 50a is arranged. In this case, the extension 106 may be only on one side, but in this embodiment, the extension 106 is formed on both sides in consideration of design. Furthermore, in order to reduce the volume feeling, the extension part 106 is inclined forward without using a laminated structure.
　また、前部配置面１０２の両側に、一段高い延長部１０６を形成することに伴って、その間には段差部１０４に連続する両側段差部１０４ａが形成される。更に、両側段差部１０４ａに伴って、傾斜面１０５に連続する両側傾斜面５０ａも形成する。そして、この両側傾斜面にもスイッチ類を配置するようにする。 Further, along with the formation of the one-step higher extension portion 106 on both sides of the front arrangement surface 102, both-side step portions 104a continuous to the step portion 104 are formed therebetween. Furthermore, the both side inclined surface 50a which continues to the inclined surface 105 is also formed with the both-side step part 104a. The switches are also arranged on the inclined surfaces on both sides.
　この実施例によれば、平滑面１２２ａの第２パームレスト１２２を利用して、キーボード２６１の入力作業の作業性を向上できる他、両側段差部１０４ａもまた第２パームレスト１２２として、あるいは手首を置いて休める領域として活用することができる。 According to this embodiment, the second palm rest 122 on the smooth surface 122a can be used to improve the workability of the keyboard 261 input operation, and the stepped portions 104a on both sides can also be used as the second palm rest 122 or with the wrist placed. It can be used as a resting area.
　また、図７の太い破線に示すように、前部配置面１０２の後方を大きな円弧１２３で形成するようにしてもよい。即ち、前部配置面１０２の後方に形成される両側の延長部１０６の後方と段差部１０４の部分とを、トラックボール２３１を中心とする大きな円弧で形成することで、前部配置面１０２の後方の両側に広い平面部１２４を形成して、この広い平面部１２４を、第２操作群２６０の操作性を向上するための第３パームレスト１２４ａとすることができる。 Further, as shown by a thick broken line in FIG. 7, the rear of the front arrangement surface 102 may be formed by a large arc 123. That is, by forming the rear part of the extension part 106 on both sides formed on the rear side of the front arrangement surface 102 and the stepped part 104 with a large arc centered on the trackball 231, A wide flat surface portion 124 is formed on both sides of the rear, and the wide flat surface portion 124 can be used as a third palm rest 124 a for improving the operability of the second operation group 260.
　また、前部配置面１０２の後方を大きな円弧１２３で形成することに伴って、前記傾斜面１０５と前記両側傾斜面５０ａとを大きな円弧状傾斜面５０ｂで形成する。そして、この円弧状傾斜面５０ｂにスイッチ類を配置すれば、スイッチ類がトラックボール２３１を中心とする円弧状で、しかも、後方が立ち上がった傾斜面（円弧状傾斜面５０ｂ）に配列されるので、視認性や操作性を向上することができる。 Further, as the rear of the front arrangement surface 102 is formed with a large arc 123, the inclined surface 105 and the both inclined surfaces 50a are formed with a large arcuate inclined surface 50b. If switches are arranged on the arcuate inclined surface 50b, the switches are arranged in an arcuate shape centered on the trackball 231 and on the inclined surface (the arcuately inclined surface 50b) rising rearward. Visibility and operability can be improved.
　図８の（ａ）図はトラックボールを含む縦断面図であり、（ｂ）図はメイン基板を含む横断面図である。図８において、この実施例では、前部配置面１０２の両側に両側段差部１０４ａを設けたとしても、後部配置面１０３との２段構造は確保されるので、第１実施例と同様な作用効果を得ることができる。しかも、一方の延長部１０６には、探触子コネクタ部５０と並んで第２探触子コネクタ部５０ａを配置できる。また、前部配置面１０２は、その周囲を傾斜面５０と両側段差部１０４ａで囲まれるので、この傾斜面にスイッチ類を配置することで、操作性を向上することができる。 8A is a longitudinal sectional view including a trackball, and FIG. 8B is a transverse sectional view including a main substrate. In FIG. 8, in this embodiment, even if both side step portions 104a are provided on both sides of the front arrangement surface 102, a two-stage structure with the rear arrangement surface 103 is ensured. An effect can be obtained. In addition, the second probe connector portion 50 a can be arranged in one extension portion 106 along with the probe connector portion 50. In addition, since the front portion placement surface 102 is surrounded by the inclined surface 50 and both side step portions 104a, operability can be improved by arranging switches on the inclined surface.
　また、図８（ｂ）図の破線に示すように、前部配置面１０２全体を、トラックボール２３１の配置部分を最下部とする凹状の湾曲面１２４（傾斜面を含む）で形成しても良い。即ち、前部配置面１０１を、トラックボール２３１の中心位置から外側に行くにしたがって徐々に立ち上がる湾曲面または傾斜面で形成するようにする。これにより、上方への突出量が大きく、利用頻度の高いトラックボール２３１を中心に、他のスイッチ類が遠くに配列されるものほど高い位置に配置されるので、視認性や操作性を向上することができる。 Further, as shown by a broken line in FIG. 8B, the entire front arrangement surface 102 may be formed of a concave curved surface 124 (including an inclined surface) with the arrangement portion of the trackball 231 as the lowermost portion. good. That is, the front arrangement surface 101 is formed by a curved surface or an inclined surface that gradually rises from the center position of the trackball 231 toward the outside. As a result, the higher the amount of upward protrusion and the higher the frequency of use of the trackball 231, the more distant the other switches are arranged at higher positions, thus improving visibility and operability. be able to.
　次に、図９を参照して、第３の実施例に係る携帯型超音波診断装置１ｂを説明する。ここで、図９は携帯型超音波診断装置の外観図であり、(ａ)図が蓋筺体を開いた状態の連結部近傍の部分正面図、（ｂ）図が蓋筺体を閉じた状態の後方部の部分平面図である。なお、同様な部位や矢印は同一符号をもって示し、重複した説明を省略する。 Next, a portable ultrasonic diagnostic apparatus 1b according to a third embodiment will be described with reference to FIG. Here, FIG. 9 is an external view of the portable ultrasonic diagnostic apparatus, where (a) is a partial front view of the vicinity of the connecting portion in a state where the lid housing is opened, and (b) is a state where the lid housing is closed. It is a partial top view of a rear part. In addition, the same site | part and arrow are shown with the same code | symbol, and the overlapping description is abbreviate | omitted.
　図１に示す前記実施例においては、蓋筺体２００を折りたたみ可能に連結するために、連結筺体２０２を本体筺体１００に対して折りたたみ可能にする水平軸で回転可能に連結し、この連結筺体２０２と表示筺体２０３とを旋回機構部２１０で連結することで、蓋筺体２００を旋回可能に連結したが、これに限定されるものではない。 In the embodiment shown in FIG. 1, in order to connect the lid housing 200 in a foldable manner, the connection housing 202 is rotatably connected to a horizontal shaft that can be folded with respect to the main body housing 100. Although the lid housing 200 is connected so as to be able to turn by connecting the display housing 203 to the turning mechanism portion 210, the present invention is not limited to this.
　例えば、図９に示すように、連結筺体２０２ａと本体筺体１００とを垂直な回転軸Ｐで旋回可能に連結し、この連結筺体２０２ａと表示筺体２０３とを水平な回転軸Ｐ１で折りたたみ可能に連結する回転軸（Ｐ、Ｐ１）を逆転する構造であってもよい。 For example, as shown in FIG. 9, the connecting case 202a and the main body case 100 are connected to each other so as to be pivotable by a vertical rotation axis P, and the connection case 202a and the display case 203 are connected to be foldable by a horizontal rotation axis P1. The structure which reverses the rotating shaft (P, P1) to perform may be sufficient.
　この場合、垂直な回転軸Ｐで旋回する表示筺体２０３の下端部を、回転軸Ｐから外側に行くにしたがって弧状または斜面で立ち上がる形状とするようにするとよい。なお、連結筺体２０２の横幅を大きくする場合は、連結筺体２０２の下端部も回転軸Ｐから外側に行くにしたがって弧状または斜面で立ち上がる形状とするようにするとよい。 In this case, the lower end portion of the display housing 203 that turns around the vertical rotation axis P may be configured to rise in an arc shape or a slope as it goes outward from the rotation axis P. In addition, when enlarging the horizontal width of the connecting housing 202, it is preferable that the lower end portion of the connecting housing 202 also has an arc shape or a shape that rises on an inclined surface as it goes outward from the rotation axis P.
　即ち、この種の携帯型超音波診断装置１ｂでは、第２操作群２６０に配置されるスイッチ類が突出するスイッチをしばしば採用する。このため、連結筺体２０２と本体筺体１００とを垂直な回転軸Ｐで旋回可能に連結すると、蓋筺体２００が突出するスイッチ類と接触する課題が生じる。このため、この実施例では、旋回する蓋筺体２００の下端部を、回転軸Ｐから外側に行くにしたがって立ちあがる形状とすることで前記課題を解決している。 That is, this type of portable ultrasonic diagnostic apparatus 1b often employs a switch from which the switches arranged in the second operation group 260 protrude. For this reason, when the connection housing 202 and the main body housing 100 are connected so as to be able to turn around the vertical rotation axis P, there arises a problem that the lid housing 200 comes into contact with the protruding switches. For this reason, in this embodiment, the above-mentioned problem is solved by making the lower end portion of the revolving lid housing 200 rise from the rotation axis P to the outside.
　これにともなって、この実施例では、図９（ｂ）図に示すように、本体筺体１００の後部形状を蓋筐体２００の下端部の形状に合わせた形状にする。これにより、蓋筐体２００を閉めた状態でも後部の角部が取れた丸みのあるコンパクトな形状とすることができる。 Accordingly, in this embodiment, as shown in FIG. 9B, the rear shape of the main body housing 100 is made to match the shape of the lower end portion of the lid housing 200. Thereby, it can be set as the round compact shape which the corner | angular part of the rear part was removed even in the state which closed the lid | cover housing | casing 200. FIG.

　この場合、前記前部配置面と前記後部配置面との間に形成される段差部に空白部を備えたパームレストを備えるようにするとより良好である。また、前記前部配置面の前部に前記第１操作群のためのパームレストを備えるようにするとよい。 In this case, it is more preferable that a palm rest provided with a blank portion is provided in a step portion formed between the front arrangement surface and the rear arrangement surface. Moreover, it is good to make it provide the palm rest for the said 1st operation group in the front part of the said front part arrangement | positioning surface.
