PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic system, irrelevant to an external design, allowing even a feeble person to safely, surely and quickly install an ultrasonic diagnostic apparatus on a pedestal of a rack.SOLUTION: An ultrasonic diagnostic apparatus is once mounted on a pedestal of a rack to eliminate a weight burden, then is slid while being guided along the recessed portions of the pedestal and disposed at a predetermined position. Alternatively, a portable ultrasonic diagnostic apparatus is slid on the pedestal and, when rear-side leg parts abut on a stopper of the pedestal, the front side of the portable ultrasonic diagnostic apparatus is placed on the pedestal, front-side leg parts are fitted in fitting parts and the portable ultrasonic diagnostic apparatus is disposed on an accurate position on the pedestal. When the portable ultrasonic diagnostic apparatus is placed on the pedestal or when the portable ultrasonic diagnostic apparatus is lifted from the pedestal, fingers holding the apparatus are disposed in the recessed portions of the pedestal to prevent the fingers of an installing person from being caught between the pedestal and the ultrasonic diagnostic apparatus.COPYRIGHT: (C)2010,JPO&INPIT【課題】外観デザインに左右されず、非力な者であっても、安全、確実、迅速に超音波診断装置を架台の台座に設置することができる超音波診断システム等を提供すること。【解決手段】超音波診断装置を一旦架台の台座に乗せることで重量負担をなくした後、超音波診断装置を台座の凹部の形状に沿って案内しながらスライドさせ、所定位置に配置する。また、台座上をスライドさせ、後側脚部が台座のストッパに突き当たった後に、携帯型超音波診断装置の前側を台座の上に下ろすことで、前側脚部が嵌合部に嵌め込み、携帯型超音波診断装置が台座上の正確な位置に配置する。さらに、携帯型超音波診断装置を台座上に下ろす際、或いは携帯型超音波診断装置を台座から持ち上げる際に、装置を把持する指を台座の凹部に配置させることで、台座と超音波診断装置との間に設置者の指が挟まれるのを防止する。【選択図】 図8
