ULTRASONIC DIAGNOSTIC DEVICE

PROBLEM TO BE SOLVED: To enhance a display processing function and also improve operability. SOLUTION: A control part reads preset data from a preset data storage part and changes a magnification corresponding to the preset data. Double enlargement is set when a user depresses an up button provided on an operation panel once, 4-times enlargement is set by the next up button operation, and further 10-times enlargement is set by the next up button operation. Also, the 4-times enlargement is set when a down button is depressed once in the state that the 10-times enlargement is set, and the double enlargement is set by the next down button operation. In such a manner, since only a preset magnification selected beforehand from many magnifications of fine steps is utilized, the number of times of operating the up button or the down button is reduced and the operability is improved. Also, the user can set a desired magnification to the preset data. That is, the enhanced enlargement and reduction function is utilized. COPYRIGHT: (C)2006,JPO&NCIPI
