Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention provides a method for transducing ultrasound diagnostics [H (device δ etc. Regarding switch purchase.

(Prior Art) Conventionally, an ultrasonic diagnostic apparatus has a second
As shown in the figure, in order to measure the size of the affected area in the ultrasonic diagnostic image 21- displayed on the CF scan screen 1, an external operation is performed to display the marker 3 that moves on both sides. 7
The operating means for moving this marker 3 is generally a joystick device or the like.

(Problem Q that the invention seeks to solve) However, in the joystick device, the operation L
The /bar is supported around two axes by drawing cymbals, and the rotation angle around each axis is detected with a potentiometer (...).
The disadvantage is that the structure is complicated and the cost is high.

Therefore, instead of the conventional joystick device, it may be possible to perform the marker movement operation using a simple combination of push buttons and switches. Four push-button switches 4a, 4b, 4c, and 4d are arranged, and when any one of the push-button switches 4a to 4d is operated, the marker is moved in the direction of the movement mark shown on the operation switch, and the marker is moved at a 45-degree angle. For directional movement, for example, push button switch 4
This is achieved by operating a and 4b simultaneously.

However, when moving a marker using such a switch structure, although it is possible to easily reduce the number of strokes by changing the switch structure to [L], it is necessary to operate two switches at the same time for movement in the 45-degree direction. However, there were problems in that it was extremely troublesome and the operability was poor.

(Means for solving the problems) The present invention has been made in view of such conventional problems.
) Therefore, we aim to reduce costs by adopting a switch structure using four pushbutton switches, and also make it possible to move the marker easily and easily with a single switch structure for movement in the 45-degree direction. An object of the present invention is to provide an eight-direction switching device with excellent operability.

In order to achieve this object, in the present invention, the center of the back surface of the switch plate is swingably supported by a support pin having a pivot-shaped shaft end, and an elastic member such as a sponge is used to move the switch plate to the switch non-operating position. Hold the switch plate in a horizontal position, change the positions by 90 degrees, and arrange four switches at equal intervals on the back side of the switch plate. When you press the part of the plate that corresponds to the switch placement position, only the corresponding single switch will be activated. When the switch is activated and a 45-degree plate portion between the switch placement positions is pressed, the two switches will be activated at the same time.

(Embodiment) FIG. 1 is a plan view showing one embodiment of the present invention.
The figure shows a cross section taken along the line ■-■ in Figure 1.

First, to explain the structure, 1 is a switch plate made by Kaloe, etc., which is a metal plate hammering method, and as is clear from Figure 1, it consists of eight arrows on the plate surface in directions shifted by 45 degrees. Operation marks 11a to 11h are drawn, and four key switches 128 to 12d shown by dotted lines are arranged on the back side of the switch plate 10 at equal intervals with their positions changed by 90 degrees.

As shown in the cross-sectional view of FIG. 2, the switch plate 10 has
The switch plate 10 is fitted into the opening 14 of the panel 13 from the back side, and a flange 15 is integrally formed around the switch plate 10 to prevent the switch plate 10 from being pumped out from the opening 14 of the panel 13. Inside the switch plate 10 is a printed circuit board 16.
is fixedly supported by a screw 18 screwed into the panel 13 with a stud 17 in between, and this printed board 1 temporary 16
A support pin 20 integrally equipped with a pivot shaft portion 19 at its tip is fixed in the center with a screw 21 from the back side of the printed circuit board 16. 19 is brought into contact with the center of the back surface of the switch plate 10, and the switch plate 10 is swingably supported within the range regulated by the opening 14 of the panel 13 using one pivot shaft as a fulcrum.

That is, as shown in an enlarged view in FIG. 3, when the right side of the switch plate 10 is pressed, for example, as shown by the arrow, the switch plate 10 moves around one pivot shaft as a fulcrum.
swings as shown at 10', and this switch plate 1
0 movement is restricted by the abutment of the flange 15 against the opening 14 of the panel 13.

Referring again to FIG. 2, key switches 12a to 12d are located at four locations on the back surface of the switch plate 10 surrounding the support pin 20, and the operating portion 22 is placed close to the back surface of the plate by soldering to the printed circuit board 16. The operating portion 22 is pushed in in response to the movement of the switch plate in response to the plate suppression operation as shown in FIG. 3, and the mechanical movement of the operating portion 22 causes the switch to be activated, e.g. It will turn on.

In addition, from the printer 1 to the board 16, there are four key switches 1.

3 is pulled out and connected to the connector 24 at the tip 9
゜ Fig. 4 is a plan view with the switch plate 10 shown in Figs. 90 around the support pin 20. Four key switches 12a to 12d are arranged at different positions each time, and a switch plate 10 shown by an imaginary line is held in a substantially horizontal state in which the switches are not operated. A cushion member 25 made of sponge rubber or the like is arranged, and this cushion member 25
As is clear from the side view of FIG. 5, the switch plate 10 is elastically held via a gap adjustment plate 26 provided at the upper part.

As is clear from the switch plate 10 in FIG. 1, notches 26 are formed at two places on the left and right sides of the flange 15 formed around the switch plate 10, and as is clear from the assembled state shown in FIG. A stud 17 for positioning and fixing the printed circuit board 16 to the back side of the panel 13 is arranged through the notch 26.
Rotation of the switch plate 10 is restricted by fitting the notch 26 into the switch plate 10.

Next, the operation of the above embodiment will be explained.

FIG. 6 is an explanatory diagram schematically showing the relationship between the switch plate 10 provided in the present invention and the four key switches 123 to 12d arranged on the back side of the switch plate 10. Operation marks 11a, 11c of switch plate '10 drawn as

Upon receiving the signal, indicate the marker on the display screen with the operation mark 11b 4
It can be moved in the 5 degree direction.

Furthermore, play 1~ where operation marks 118~11g were removed
By pressing and turning the surface in a circular motion, if the speed of pressing and turning is constant, a special movement operation is possible in which the marker can be moved in a substantially rectangular shape.

(Effects of the Invention) As described above, according to the present invention, the center of the back surface of the switch plate is swingably supported by a support pin having a pivot-shaped shaft end, and the switch plate is supported by a cushion member such as a sponge. The switches are held in a horizontal state, which is the non-operating position, and the four switches are arranged at equal intervals on the back side of the switch plate, changing their positions 90 degrees at a time, so that when the part of the plate opposite to the switch position is pressed, Only the corresponding single switch is actuated to move the marker in a predetermined 90 degree direction determined by the switch output, while the marker can be moved in a 45 degree direction between the switch positions. When the part is pressed to 1, two switches located on both sides of the J operation part are activated simultaneously by the rocking of the switch plate whose center is supported by the pivot shaft, and in response to these two switch signals, the marker is set to 45. Even with four switches, the marker can be moved in eight directions with a single switch operation, making it extremely easy to operate the switch to move the marker on the display screen. Become. Also,
Since it is only necessary to use four switches, the switch structure is greatly simplified compared to the conventional jaw stick device, and costs can be reduced without impairing operability.
