Embodiments of the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to the following embodiments, and can be modified as appropriate without departing from the gist thereof. Further, in the drawings described below, parts having the same functions are given the same reference numerals, and the description thereof may be omitted or simplified.

<First embodiment>
An ultrasound diagnostic apparatus including an electronic device according to the first embodiment will be described below.

(composition)
FIG. 1 is a diagram showing the configuration of an ultrasonic diagnostic apparatus according to this embodiment. The ultrasonic diagnostic apparatus 1 is an apparatus that generates an ultrasonic image using reflected waves obtained by projecting ultrasonic waves onto a subject (not shown).

The ultrasound diagnostic apparatus 1 includes a transmitting/receiving section 10, a signal processing section 20, an image data generating section 30, an image data storage section 40, an image data processing section 50, a display control section 60, a display section 70, and a system control section 80. It is also an example of medical equipment. The medical device may be an X-ray imaging device, a CT device, an MRI device, or the like.

The ultrasonic probe 11 of the ultrasonic diagnostic apparatus 1 uses an electric signal as a timing signal, transmits ultrasonic waves to the subject from a built-in piezoelectric vibrator, receives reflected waves, and converts the received reflected waves into electrical signals. (reflected wave signal). Further, the ultrasound probe 11 is a medical instrument for performing at least one of observation, examination, and treatment on a subject.

The transmitter/receiver unit 10 controls the transmission and reception of ultrasound performed by the ultrasound probe 11 . The transmitting/receiving section 10 includes a transmission delay circuit and the like, and supplies a driving signal to the ultrasound probe 11. The transmitting/receiving unit 10 repeatedly generates rate pulses at a predetermined repetition frequency (PRF). Further, the transmission delay circuit of the transmitting/receiving section 10 focuses the ultrasonic waves generated from the ultrasound probe 11, and gives a delay time for determining the transmission directivity to the rate pulse generated by the transmitting section. This transmission delay circuit can control the transmission direction of the ultrasound transmitted from the transducer by changing the delay time given to the rate pulse.

Further, the transmitter/receiver 10 includes an amplifier, an A/D converter, a reception delay circuit, an adder, and the like. Various processes are performed on the reflected wave signal received by the ultrasound probe 11 to generate an ultrasound signal. The amplifier amplifies the reflected wave signal for each channel and performs gain correction processing. The A/D converter performs A/D conversion on the gain-corrected reflected wave signal. The reception delay circuit gives digital data a delay time in order to determine reception directivity. The adder performs addition processing of the reflected wave signals to which a delay time is given by the reception delay circuit. The addition process of the adder emphasizes the reflected component from the direction corresponding to the reception directivity of the reflected wave signal.

The transmitting/receiving unit 10 causes the ultrasound probe 11 to transmit two-dimensional ultrasound waves when performing two-dimensional scanning of the subject. Then, the transmitting/receiving unit 10 generates a two-dimensional ultrasound signal from the two-dimensional reflected wave signal received by the ultrasound probe 11. Furthermore, when performing three-dimensional scanning of the subject, the transmitting/receiving unit 10 causes the ultrasound probe 11 to transmit three-dimensional ultrasound waves. The transmitting/receiving unit 10 then generates a three-dimensional ultrasound signal from the three-dimensional reflected wave signal received by the ultrasound probe 11.

The signal processing section 20 performs various signal processing on the ultrasound signal output from the transmitting/receiving section 10. Specifically, the signal processing unit 20 performs signal processing such as detection processing and logarithmic compression on the ultrasound signal. The signal processing unit 20 visualizes the amplitude information of the ultrasound signal and generates signal processing data (raster data). A bandpass filter process is performed on the ultrasonic signal output from the transmitting/receiving section 10, and then the envelope of the output signal is detected. Then, the detected data is compressed by logarithmic transformation. The signal processing section 20 outputs the signal processing data after signal processing to the image data generation section 30.

The image data generation section 30 generates an ultrasound image using the signal processing data processed by the signal processing section 20. The image data generation section 30 includes a digital scan converter and converts the signal processing data into data expressed in orthogonal coordinates. Here, the image data generation unit 30 orthogonally transforms the signal processing data (raster data) into the coordinate system (X, Y) of the image data for display. The image data generation unit 30 then generates an ultrasound image (B-mode image data) in which the signal intensity is expressed by the brightness of the luminance. In this way, the image data generation unit 3
At 0, an ultrasound image is generated. As an ultrasound image generation algorithm, image reconstruction can be performed by applying not only a delay-and-add process but also an arbitrary algorithm.

Further, the image data generation unit 30 can generate blood flow image data using a color Doppler method called a color flow mapping method (CFM). In the color Doppler method, ultrasonic waves are transmitted multiple times in the same direction, and frequency analysis based on the Doppler effect is performed on the received reflected wave signals to extract blood flow motion information. The display control unit 60 uses the color Doppler method to generate blood flow information such as average velocity, variance, and power as blood flow image data. Note that the image data generation unit 30 may generate blood flow image data using the power Doppler method.

The image data storage unit 40 receives and stores image data from the image data generation unit 30, and the image data processing unit 50 generates cross-sectional images and three-dimensional stereo images from the image data stored in the image data storage unit 40. do.

The display control unit 60 displays the ultrasound image and its region of interest (ROI) on the display unit 70 . The display control unit 60 also receives signals output from the acquisition unit of the electronic device in response to operations by the operator, and controls various functions such as the zoom magnification of the ultrasound image and switching between orthogonal three-sectional images and three-dimensional three-dimensional images. Performs display processing. The display control unit 60 uses a GUI (Graphical
User Interface). Thereby, the display control unit 60 changes the zoom magnification of the ultrasound image on the screen of the display unit 70, for example, in conjunction with the operation of the electronic device 100. Details of the GUI of the display control unit 60 for each operation device of the electronic device 100 will be described later.

The system control unit 80 is executed by the transmitting/receiving unit 10, the signal processing unit 20, the image data generating unit 30, the image data storage unit 40, and the image data processing unit 50 based on the operation signal from the acquisition unit 130 of the electronic device 100. Controls various processes that are performed.

The electronic device 100 of this embodiment is attached to the ultrasound diagnostic apparatus 1. The electronic device 100 includes a base material 110, a detection section 120, an acquisition section 130, a vibration control section 140, and a vibration generation section 150.

The base material 110 has an operating section on its outer surface that serves as the operating panel of the ultrasound diagnostic apparatus 1, which is made up of at least one of a plurality of protrusions and recesses that serve as operating devices such as switches, dial trackballs, and sliders, as described later. It is formed. The operator operates the ultrasonic diagnostic apparatus 1 by touching the operation section of the base material 110 with a finger. The base material 110 is attached to a pedestal 121 of the detection unit 120.

The detection unit 120 includes a pedestal 121, a detection sensor 122 that detects at least one of force and moment that is applied when an operator touches the base material 110, and a vibration generation unit 150, and is configured by a vibration generation unit 150. Detect. The pedestal 121 is attached to the detection sensor 122 and configured as an attachment to the base material 110. The detection sensor 122 is, for example, a 6-axis force sensor using a strain gauge. The detection sensor 122 may be a 6-axis force sensor that can detect the point of action or the position and moment of force at the point of action with a single detection sensor, or a 1-axis or 3-axis force sensor, or a piezoelectric sensor. A tactile sensor (surface pressure sensor) element may be employed.

The acquisition unit 130 acquires the point of action of the operator's finger based on the data detected by the detection unit 120. Thereby, the acquisition unit 130 has a function of acquiring positional information regarding the operation on the base material based on the output of the detection unit in response to the detection of the operation. The acquisition unit 130 uses an operation map 160 in which an operation area is determined according to a convex portion and/or a recess that is an operation portion on the base material 110, and determines whether the calculated point of action is within the operation area of the operation map 160. Sometimes it is determined that there has been an operation. The operation map 160 is functional information regarding a function performed by operating at least one of the convex portion and the concave portion. A predetermined function for operating the ultrasound diagnostic apparatus 1 is assigned to each operation area of the operation map 160.

Further, the acquisition unit 130 is connected to the display control unit 60 and system control unit 80 of the ultrasound diagnostic apparatus 1. When the acquisition unit 130 determines that an operation has been performed, the acquisition unit 130 acquires operation information of a predetermined function based on the force position and moment of the detection sensor 122, and uses the acquired operation information as an operation signal to send to the display control unit 60 and the system. It is output to the control section 80. Thereby, the acquisition unit 130 acquires operation information of the operator on at least one of the convex portion and the concave portion based on at least one of the force and moment detected by the detection unit. Furthermore, the acquisition unit 130 also functions as a control unit that controls the operation of the electronic device based on the position information and functional information. Further, the acquisition unit 130 outputs a vibration signal corresponding to operation information of a predetermined function to the vibration control unit 140.

The vibration control unit 140 controls the vibration of the vibration generation unit 150 based on the signal from the acquisition unit 130 in order to notify the operator that the operation unit is being operated. The vibration generation unit 150 uses a vibration actuator such as a piezoelectric element or a voice coil motor, and is attached to the pedestal 121 of the detection unit 120. Under the control of the vibration control unit 140, the vibration generation unit 150 vibrates the pedestal 121 and provides force feedback, which is vibration feedback, to the operator who is touching the base material 110. This allows the operator to recognize that an operation will be performed via the operation unit on the base material 110.

(exterior)
FIG. 2A is a perspective view showing the external appearance of the electronic device 100, display section 70, ultrasound probe 11, and cable 12 that serve as the operation panel of the ultrasound diagnostic device 1, and FIG. 2B is a perspective view of the ultrasound diagnostic device 1. FIG. 3 is a top view of the operation panel. A base material 110 is provided on the outer surface of the ultrasonic diagnostic apparatus 1, and a display section 70 is provided adjacent to the base material 110. Note that although the present embodiment shows an example in which the display section 70 is configured integrally with the base material 110, the configuration of the present invention is not limited to this. For example, by configuring the display unit 70 with a thin liquid crystal display or the like and connecting the housing of the ultrasound diagnostic apparatus 1 and the display unit 70 with a movable arm, a configuration in which the orientation of the display unit 70 can be arbitrarily changed can be achieved. I don't really mind.

The ultrasound probe 11 is a medical device that is connected to the housing of the ultrasound diagnostic apparatus 1 via a cable 12. The cable 12 is made of a soft material such as rubber, silicone, or polyvinyl chloride, and has an electric cable built therein for transmitting and receiving electric signals. The drive signal transmitted by the transmitter/receiver 10 is transmitted to the ultrasound probe 11 through the cable 12, and the echo signal received by the ultrasound probe 11 is transmitted to the transmitter/receiver 10 through the cable 12. Since the cable 12 is made of a flexible and flexible material, the operator can bend the cable 12 and move the ultrasound probe 11 to a desired inspection site.

(electronic equipment)
The electronic device 100 is arranged as an operation panel of the ultrasound diagnostic apparatus 1. A base material 110 is provided on the outer surface of the electronic device 100 , and a surface of the base material 110 opposite to the outer surface is attached to a pedestal 121 of the detection unit 120 . The detection unit 120 includes a pedestal 121 (not shown), a detection sensor 122, and a vibration generation unit 150.

As shown in FIG. 2B, the base material 110 includes a slide switch section 111 composed of oval recesses 111a, 111b, and 111c, and linear protrusions 112a, 112b, 112c, 112d, and 112e. It has a slider section 112. Furthermore, the base material 110 has a dial portion 113 composed of truncated cone-shaped convex portions 113a, 113b, and 113c. The base material 110 also has a dial trackball portion 114 that is a combination of a circular recess 114a that forms a groove with respect to the flat surface and a hemispherical convex portion 114b that projects inside the recess 114a.

The base material 110 is made of a material that is not easily deformed by an operator's operation, such as resin or glass. Further, the outer surface of the base material 110 is formed as an integrated operation panel. Therefore, even if a disinfectant liquid such as alcohol is sprayed onto the base material 110, the liquid does not reach the detection sensor 122 of the detection unit 120 or the vibration generation unit 150, so that the electronic device 100 does not malfunction due to a short circuit or the like. That is, the base material 110, which is the operation panel, can be cleaned by spraying a liquid such as a disinfectant, and the hygiene of the electronic device 100 can be maintained.

Further, in the base material 110, the plane portion 119 other than the operation portions of the slide switch portion 111, the slider portion 112, and the dial portion 113 is an area in which the acquisition portion 130 does not accept any operation even if touched by the operator. Therefore, when the operator unintentionally touches the flat portion 119, the detection sensor 122 described below detects the position and force of the operator's touch, but the acquisition unit 130 does not determine this as an operation. Thereby, even if the operator touches the flat part 119, no function is executed in the electronic device 100, so that it is possible to prevent an erroneous operation caused by the operator unintentionally touching the flat part 119. Further, when the operator touches the flat part 119, the vibration generating part 150 does not vibrate the pedestal 121, that is, the base material 110 (the flat part 119) under the control of the vibration control part 140. Therefore, by touching the flat portion 119, the operator can recognize that the electronic device is not being operated.

FIG. 3 is an explanatory diagram showing the coordinates of the detection sensor 122 and the coordinates of the point of action when the electronic device 100 shown in FIGS. 2A and 2B is used. In addition, in FIG. 3, illustration of the convex part and the concave part of the operation part of the base material 110 is omitted for explanation.

A six-axis force sensor, which is an example of the detection sensor 122, measures at least one of force and moment when an operator touches the base material 110 with a finger. The acquisition unit 130 calculates the coordinates P (Px, Py, Pz) of the point of action that the finger contacts from the force and/or moment measured by the detection sensor 122.

As shown in FIGS. 3A and 3B, the forces in the Xs, Ys, and Zs axis directions of the 6-axis force sensor are Fx, Fy, and Fz, and the moments around each axis are Mx, My, and Mz. The coordinates P (Px, Py, Pz) of the point of application of the finger force are calculated by the following equations (1) to (3). Here, L is the distance from the origin of the 6-axis force sensor to the surface of the base material. Note that the exerted forces Fx, Fy, and Fz in the axial direction are vectors indicating the magnitude and direction of the contact force.

FIG. 4 is a diagram illustrating an example of the operation map 160 that the acquisition unit 130 has. The operation map 160 has an operation area that overlaps with the coordinates of a convex portion and/or a recess that is an operation portion provided on the base material 110. A predetermined function for operating the ultrasound diagnostic apparatus 1 is assigned to each operation area of the operation map 160. In the case of FIG. 4, the operation area 161 corresponds to the slide switch section 111, the operation area 162 corresponds to the slider section 112, the operation area 163 corresponds to the dial section 113, and the operation area 164 corresponds to the dial trackball section 114. Further, the area of the plane portion of the base material 110 other than the operation section is a non-operation area 165 that does not accept operations by the operator.

The acquisition unit 130 acquires position information indicating the point of action and operation information indicating the operation of the operation unit based on the force and/or moment from the detection sensor 122. Based on the acquired position information and operation information, the acquisition unit 130 transmits an operation signal indicating a predetermined function assigned to each operation area of the operation map 160 to the display control unit 60 of the ultrasound diagnostic apparatus 1 or to the system control unit 130. It has a function of outputting to the section 80. At the same time, the acquisition unit 130 has a function of outputting a vibration signal corresponding to operation information of a predetermined function to the vibration control unit 140.

For example, the acquisition unit 130 has a determination function that determines that the operator is touching the slide switch unit 111 when it is specified from the position information that the point of action of the operator's finger is in the operation area 161. When the operator operates the slide switch unit 111 with a finger, the acquisition unit 130 has a function of acquiring the movement direction of the force of the detection sensor 122 as operation information, and outputs a slide switch operation signal to the system control unit 80. There is. Further, the acquisition unit 130 has a function of outputting a vibration signal corresponding to the operation of the slide switch by the operator to the vibration control unit 140.

FIG. 5 is a flowchart of the operation process of the acquisition unit 130 executed in the electronic device 100. In step S501, the acquisition unit 130 has a function of determining whether the measured value of the force Fz in the Zs-axis direction from the detection sensor 122 (six-axis force sensor) is greater than or equal to a predetermined value. When the measured value is equal to or greater than the predetermined value, the acquisition unit 130 advances the process to step S502. If it is less than or equal to the predetermined value, the acquisition unit 130 repeats the process of step S501 without performing any subsequent processing. By providing a threshold value for determining the measured value by the detection sensor 122 in this way, it is possible to prevent malfunctions when the operator accidentally touches the base material.

In step S502, the acquisition unit 130 calculates the coordinates P of the operator's point of action using equations (1) to (3) above. Then, in step S503, the acquisition unit 130 determines whether the point of action of the operator's finger is within any operation area of the operation map 160 based on the calculated coordinates. When the point of action is outside the operation area, the acquisition unit 130 returns the process to step S501. Further, when the point of action is within the operation area, the acquisition unit 130 advances the process to step S504.

In step S504, the acquisition unit 130 acquires operation information based on the force and/or moment measured by the detection sensor 122, and transmits the operation signal indicating the function assigned to the operation area overlapping the point of action to the display control unit. 60 or the system control unit 80. The display control unit 60 or the system control unit 80 controls execution of a predetermined function based on the operation signal.

In step S505, the acquisition unit 130 transmits a vibration signal corresponding to a predetermined function to the vibration control unit 140. The vibration control unit 140 operates a vibration actuator, which is a vibration generation unit 150, based on the vibration signal, and provides haptic feedback to the operator to inform the operator that the operation is actually being performed. Therefore, by touching the slide switch section 111, the operator can recognize that he/she is operating the electronic device.

In step S506, the acquisition unit 130 determines whether the operator's operation has ended. For example, if the detection unit 120 has not detected the object continuously for a predetermined period of time, the acquisition unit 130 determines that the operator's operation has ended and ends the process of this flowchart. If the detection by the detection unit 120 is performed within the predetermined time, the acquisition unit 130 determines that the operation has not been completed and returns the process to step S501.

Next, predetermined functions of the ultrasonic diagnostic apparatus 1 corresponding to each of the convex portions and concave portions constituting the operating portion of the base material 110 will be described.

(slide switch)
FIG. 6 is an enlarged perspective view of an elliptical recess that is an operating section provided in the base material 110, and is the recess 111a shown in FIG. The operation area of the operation map 160 in this case is the operation area 161a corresponding to the recess as shown in FIG. 130, it is determined that there is an operation. The recess 111a, which is an oval recess, has a switching function similar to a mechanical slide switch.

Further, as shown in FIG. 6 , a flat portion 111 d around the recess 111 a in the base material 110 is not an operation area of the operation map 160 . Therefore, as shown in FIG. 3, when the operator touches the flat part 111d, the coordinates and force of the contact position are detected, but the acquisition unit 130 detects that the contact with the flat part 111d is not related to the operator's operation. It does not make a judgment and does not accept operations based on the contact. That is, the flat portion 111d of the base material 110 does not have the switching function that the recessed portion 111a has.

FIG. 7 shows an example of a slide switch in the GUI displayed by the display control unit according to the present embodiment. For example, the recessed portion 111a, which is a slide switch portion, is assigned the function of switching between starting and stopping transmission of ultrasound by the ultrasound probe 11. The state of the recess 111a shown in FIG. 7A is a state in which the start of ultrasound transmission by the ultrasound probe 11 is accepted. The "start" position shown in FIG. 7A corresponds to the end 111a1 of the oval recess shown in FIG.

As shown in FIG. 7A, when "Start" is displayed on the GUI, the operator touches the end 111a1 (FIG. 6) of the oval recess with his or her finger, and continues to touch the end 111a2 (FIG. 6) of the oval recess with his or her finger. Slide. At this time, the acquisition unit 130 outputs an operation signal instructing switching to the ultrasound probe 11. The ultrasound probe 11 starts transmitting ultrasound according to the operation signal input from the acquisition unit 130. At this time, the GUI display in FIG. 7A switches from start to stop as shown in FIG. 7B. Note that the display position of "stop" in FIG. 7B corresponds to the end 111a2 of the oval recess. Here, when the acquisition unit operator touches the end 111a2 of the oval recess with his finger and slides his finger to the opposite end 111a1, the acquisition unit 130 sends an operation signal instructing the ultrasound probe 11 to switch. Output. The ultrasound probe 11 stops transmitting ultrasound according to the operation signal input from the acquisition unit 130. In this way, the ultrasound probe 11 switches between starting and stopping the transmission of ultrasound according to the operation signal input from the acquisition unit 130. Note that the slide switch section 111 is not limited to an elliptical concave three-dimensional section, but may be a substantially rectangular or convex three-dimensional section, and the GUI shown in FIG. The shape should be similar to that of the

The vibration control unit 140 controls the vibration generation unit 150 when the operator's finger touches the oval ends 111a1 and 111a2 or when the operator slides the finger to switch start/stop of ultrasonic transmission. , the pedestal 121, that is, the base material 110 is vibrated. More specifically, the vibration generation unit 150 vibrates the elliptical ends 111a1 and 111a2. Thereby, the operator can receive haptic feedback when operating the recess 111a to switch start/stop of ultrasonic transmission. Therefore, the operator can recognize that he/she is operating the electronic device. Further, when the operator touches the flat part 111d, the vibration generating part 150 does not vibrate the pedestal 121, that is, the base material 110 (the flat part 111d) under the control of the vibration control part 140. Therefore, by touching the flat portion 111d, the operator can recognize that the electronic device is not being operated.

(Slider)
8A and 8B are enlarged perspective views of a base material having a total of two or more linear convex portions, which is the slider portion 112 of FIG. 2. FIG. As shown in FIG. 4, the operation area in the operation map 160 is an operation area 162 corresponding to the convex parts 112a to 112e, and when the point of action of the finger is within the operation area, the acquisition unit 130 operates the slider unit 112. It is determined that there is. The convex portions 112a to 112e have a shape extending in one direction when the base material is viewed from above, and have a slider function similar to a mechanical sliding variable resistor. For example, in the operation map 160, the slider unit 112 is assigned a function of adjusting the gain (brightness) at each depth corresponding to an ultrasound image.

Further, as shown in FIGS. 8A and 8B, the flat portion 112f around the convex portions 112a to 112e on the base material 110 is not the operation area of the operation map 160. Therefore, as shown in FIG. 3, when the operator touches the flat part 112f, the coordinates and force of the contact position are detected, but the acquisition unit 130 detects that the contact with the flat part 112f is not related to the operator's operation. No judgment is made and no operation is accepted due to the contact. That is, the flat portion 112f of the base material 110 does not have the slider function that the convex portions 112a to 112e have.

When the operator touches any of the protrusions 112a to 112e with his finger and slides the finger, the acquisition unit 130 outputs an operation signal instructing movement to the slide position in accordance with the finger operation. On the other hand, when the operator taps a point on the protrusions 112a to 112e without sliding the finger on the protrusions 112a to 112e, the acquisition unit 130 acquires the position coordinates of the tapped point of action and obtains it on the GUI. Outputs an operation signal to move the knob to the position indicated by the coordinates.

9A to 9D are diagrams showing examples of slider display on the GUI of the display control unit according to the present embodiment. As shown in FIG. 9A, the GUI displays slide bars 72a to 72e, which are sliders corresponding to the convex portions 112a to 112e, and knobs 74a to 74d, which indicate the current positions on the sliders. Note that in FIGS. 8B to 9D, the symbols of the slide bar and the knob are omitted. The knobs 74a to 74e are indicators that indicate the values at the current positions of the variable amounts by operating the slide bars 72a to 72e, respectively. For example, from the initial state shown in FIG. 9A, when the operator touches the center of the convex portion 112a located at the top with a finger and performs a sliding operation to the right, the knob 74a moves as shown in FIG. 9B. On the other hand, when the operator sequentially taps each arrow position shown in FIG. 8B with a finger without performing a sliding operation, the knobs 74a to 74e move to the tapped positions on the GUI as shown in FIG. 9C. In this way, by moving the knobs 74a to 74e according to the point of action, which is the tap position of the finger, the operator can quickly change the settings of each slider.

Further, as an example, if the operator repeatedly taps (double taps) the position of the convex portion 112a corresponding to the knob 74a twice after setting each slider, the current relative position of each knob 74a to 74e is fixed. . As a result, when the operator slides one of the protrusions 112a to 112e to the left with his or her finger, all the knobs 74a to 74e simultaneously move to the left while maintaining their relative positions on the GUI, as shown in FIG. 9D. Move to. In this way, the operator can easily change settings using the slide bars 72a to 72e. Note that when fixing the relative positions of the respective knobs 74a to 74e, in addition to double tapping any of the knobs 74a to 74e, a long press may be used. Furthermore, a slide switch section similar to the slide switch section 111 is provided near the protrusions 112a to 112e (in this case, "start" and "stop" shown in FIGS. 7A and 7B are replaced with "fixed" and "fixed", respectively). (changed to "cancel") is also acceptable. This allows the operator to switch between fixing and moving the positions of each of the knobs 74a to 74e by operating the slide switch section.

Note that the convex parts 112a to 112e are not limited to convex three-dimensional parts, but may also be concave three-dimensional parts.In addition, the convex parts 112a to 112e are not limited to convex three-dimensional parts, but may be concave three-dimensional parts. It is preferable that the shape is similar to that shown. The vibration control unit 140 also controls the vibration generation unit 150 to cause the pedestal 121, that is, the base material 110 (convex portions 112a to 112e ) to vibrate. This allows the operator to receive haptic feedback when operating the protrusions 112a to 112e. Therefore, the operator can recognize that he/she is operating the electronic device. Further, when the operator touches the flat part 112f, the vibration generating part 150 does not vibrate the pedestal 121, that is, the base material 110 (the flat part 112f) under the control of the vibration control part 140. Therefore, by touching the flat portion 112f, the operator can recognize that the electronic device is not being operated.

(Dial)
FIG. 10 is an enlarged perspective view of a base material having a truncated conical convex portion 113a, which corresponds to the convex portion 113a forming the dial portion 113 in FIG. Note that the convex portions 113b and 113c are also configured in the same manner as the convex portion 113a. As shown in FIG. 4, the operation area in the operation map 160 is an operation area 163 corresponding to the convex parts 113a to 113c, and when the point of action of the finger is within the operation area, the acquisition unit 130 operates the dial unit 113. It is determined that there is. The convex portions 113a to 113c have the function of switching switches by rotating them similarly to mechanical dial switches. For example, in the operation map 160, the dial section 113 is assigned a function of changing the gain (brightness) of the amplifier of the transmitting/receiving section 10.

Further, as shown in FIG. 10 , a flat portion 113 d around the convex portion 113 a of the base material 110 is not an operation area of the operation map 160 . Therefore, as shown in FIG. 3, when the operator touches the flat part 113d, the coordinates and force of the contact position are detected, but the acquisition unit 130 detects that the contact with the flat part 113d is not related to the operator's operation. It does not make a judgment and does not accept operations based on the contact. That is, the flat portion 113d of the base material 110 does not have the switching function that the convex portion 113a has. Note that the flat portions around the convex portions 113b and 113c are also configured as areas that do not accept operations, similar to the flat portion 113d described above.

When the operator pinches and twists the truncated conical side surfaces of the protrusions 113a to 113c with his fingers, the detection sensor 122 detects the moment Mz about the Zs axis in the protrusions 113a to 113c. Then, the acquisition unit 130 outputs a switch switching instruction signal based on the detected moment, and the gain is changed. Further, the vibration control unit 140 causes the vibration generation unit 150 to control the pedestal 121 when the operator pinches the protrusions 113a to 113c with his or her fingers or twists the protrusions 113a to 113c to change the gain. That is, the base material 110 (convex portions 113a to 113c) is vibrated. This allows the operator to receive haptic feedback when operating the convex portions 113a to 113c. Therefore, the operator can recognize that he/she is operating the electronic device. Further, when the operator touches the flat part 113d, the vibration generating part 150 does not vibrate the pedestal 121, that is, the base material 110 (the flat part 113d) under the control of the vibration control part 140. Therefore, by touching the flat portion 113d, the operator can recognize that the electronic device is not being operated.

(dial trackball)
FIG. 11 shows a circular recess 114a and a hemispherical protrusion 114 protruding inside the recess 114a.
FIG. 3 is an enlarged perspective view of a base material having an operating section combined with FIG. Further, FIG. 12 is a perspective view showing an operation area 164a, an operation area 164b, and a non-operation area 164c corresponding to the dial trackball section 114 in the operation map 160.

As shown in FIGS. 11 and 12, the shape of the convex portion 114b corresponding to the operation area 164b is a circular shape formed by a part of a hemisphere. Further, a non-operation area 164c provided so as to surround the operation area 164b is an annular area provided on the inclined surface of the convex portion 114b. Furthermore, the shape of the recess 114a corresponding to the operation area 164a provided so as to surround the non-operation area 164c is also an annular area.

As shown in FIG. 12, in the operation map 160, the operation area of the dial trackball unit 114 is divided into two operation areas 164a and 164b and a non-operation area 164c that does not accept operations provided between the operation areas 164a and 164b. It consists of When the operator operates the dial trackball unit 114 with a finger, when the point of action of the finger is within either of the operation areas 164a, 164b, the acquisition unit 130 determines that the dial trackball unit 114 is being operated. .

Further, as shown in FIG. 11 , a flat portion 114 d around the dial trackball portion 114 on the base material 110 is not an operation area of the operation map 160 . Therefore, as shown in FIG. 3, when the operator touches the flat part 114d, the coordinates and force of the contact position are detected, but the acquisition unit 130 detects that the contact with the flat part 114d is not related to the operator's operation. It does not make a judgment and does not accept operations based on the contact. That is, the flat portion 114d of the base material 110 does not have the function of a dial trackball portion that the recessed portion 114a and the raised portion 1134b have.

Furthermore, as will be described later, the functions assigned to the operation area 164b of the convex portion 114b and the functions assigned to the operation area 164a of the recess 114a are different from each other. Therefore, when operating the dial trackball section 114, the operator can switch between different functions by using the convex portion 114b and the concave portion 114a. Furthermore, parts of the convex portion 114b and the concave portion 114a corresponding to the operation areas 164a and 164b are painted with different colors, or are subjected to different surface treatments (processing to have different surface roughness due to graining, smoothing, etc.). You may also This makes it possible to prevent visual and/or tactile erroneous operations when operating the dial trackball section 114. Note that the hemispherical shape of the convex portion 114b is not limited to the shape shown in FIGS. 11 and 12 in which a sphere is halved parallel to the flat surface, but may also be formed by, for example, cutting a portion of a sphere along an arbitrary plane. may be adopted.

Further, the recessed portion 114a has a function of switching the switch by operating the rotation direction similarly to a mechanical dial switch. For example, the function of changing the size of the displayed image is assigned to the operation area 164a of the recess 114a. Further, the convex portion 114b has functions such as a pointing device, screen scrolling, and display rotation, similar to a mechanical trackball. For example, the operation area 164b of the convex portion 114b is assigned functions such as moving a cursor, determining the position of an ROI, arranging a measurement tool, and rotating a three-dimensional stereoscopic image.

Next, with reference to FIGS. 13A to 13C, a three-dimensional stereoscopic image displayed on the display unit 70 when each of the above-mentioned operating units is operated will be described. In the example shown in FIGS. 13A to 13C, a model 76 is displayed on the display section 70. The three-dimensional stereo image display screens illustrated in FIGS. 13A to 13C are examples of operation screens for operating the electronic device.

When the operator touches the recess 114a with a finger and moves the finger in the circumferential direction of the recess 114a, the acquisition unit 130 outputs an operation signal according to the distance the finger has moved. For example, assume that in the operation map 160, the function of enlarging and reducing a three-dimensional stereo image is assigned to the operation area 164a of the recess 114a. In this case, when the operator moves the finger touching the recess 114a clockwise, the model 76 displayed on the display section 70 is enlarged as shown in FIGS. 13A to 13B. Further, when the operator moves the finger that touched the recess 114a in a counterclockwise direction, the model 76 displayed on the display section 70 is reduced in size.

On the other hand, when the operator touches the convex portion 114b with a finger and moves the finger directly on the convex portion 114b, the acquisition unit 130 outputs an operation signal according to the moving distance of the finger. For example, assume that in the operation map 160, the function of rotating a three-dimensional stereo image is assigned to the operation area 164b of the convex portion 114b. In this case, when the operator moves the finger touching the convex part 114b from the top to the bottom of the convex part 114b in FIG. 2B, the model 76 displayed on the display part 70 as shown in FIGS. 13A to 13C , the head is rotated so that it moves toward the front and the legs move toward the back. In this way, the display control unit 60 controls the display of the operation screen by the display unit 70 so as to display the result of the operation indicated by the operation information.

The vibration control unit 140 causes the vibration generation unit 150 to vibrate when the operator touches the recess 114a with a finger or when the operator moves the finger that has touched the recess 114a a predetermined distance in the circumferential direction. In addition, when the operator touches the convex portion 114b with a finger or when the operator moves the finger touching the convex portion 114b a predetermined distance on the hemisphere, the vibration control unit 140 causes the vibration generating unit 150 to The pedestal 121, that is, the base material 110 (the recesses 114a and the protrusions 114b) is vibrated. Furthermore, when the operator's finger touches an area corresponding to the non-operation area 164c between the recess 114a and the protrusion 114b, the vibration control unit 140 causes the vibration generation unit 150 to control the pedestal 121, that is, the base. Do not vibrate the material 110. More specifically, the vibration control unit 140 does not cause the vibration generation unit 150 to vibrate the portion between the concave portion 114a and the convex portion 114b and the flat portion 114d. That is, the non-operation area 164c functions as an area on the base material between areas in which at least one of a convex part and a concave part is set with a different function, and in which the control unit does not receive an operation by the operator. Thereby, the operator can recognize that the finger has moved from the operation area (a state in which vibrations of the vibration generation unit 150 are generated) to a non-operation area (in a state in which vibrations of the vibration generation unit 150 are not generated), It is possible to prevent erroneous operation due to touching another operation area.

Next, modifications of the convex portions and concave portions provided on the base material described above will be described with reference to FIGS. 14 to 17.

(push switch)
FIG. 14 is a perspective view of the push switch section 115, which is a hemispherical recess. In the operation map 160, the operation area of the push switch section 115 corresponds to the area where the recess is formed. The push switch section 115 has a function of switching ON/OFF by pressing a concave portion, similar to a mechanical push switch. When the operator presses the push switch section 115 with a finger, the acquisition section 130 outputs an ON/OFF signal. Note that the push switch portion 115 is not limited to a concave portion, but may be configured in other shapes such as a convex portion. Further, the vibration control unit 140 causes the vibration generation unit 150 to vibrate the pedestal 121, that is, the base material 110 (push switch unit 115) when the operator presses the recessed portion of the push switch unit 115 with a finger. This allows the operator to receive haptic feedback when operating the push switch section 115. Therefore, the operator can recognize that he/she is operating the electronic device.

Further, as shown in FIG. 14 , a flat portion 115 a around the push switch section 115 in the base material 110 is not an operation area of the operation map 160 . Therefore, as shown in FIG. 3, when the operator touches the flat part 115a, the coordinates and force of the contact position are detected, but the acquisition unit 130 detects that the contact with the flat part 115a is not related to the operator's operation. It does not make a judgment and does not accept operations based on the contact. That is, the flat portion 115a of the base material 110 does not have the function that the push switch portion 115 has. Further, when the operator touches the flat part 115a, the vibration generating part 150 does not vibrate the pedestal 121, that is, the base material 110 (the flat part 115a) under the control of the vibration control part 140. Therefore, by touching the flat portion 115a, the operator can recognize that the electronic device is not being operated.

(knob dial)
FIG. 15 is a perspective view of the knob dial portion 116, which is a rectangular convex portion. In the operation map 160, the operation area of the knob dial portion 116 corresponds to the area where the convex portion is formed. The knob dial portion 116 has a function of switching the switch by rotating the convex portion, similar to a mechanical knob dial switch. When the operator pinches and twists the convex portion with his fingers, the detection sensor 122 detects the moment Mz about the Zs axis in the convex portion, and the acquisition unit 130 outputs a signal instructing to switch the switch. Furthermore, when the operator pinches or twists the convex portion of the dial portion 116 with his/her fingers, the vibration control portion 140 causes the vibration generation portion 150 to control the pedestal 121, that is, the base material 110 (the dial portion). 116) to vibrate. This allows the operator to receive haptic feedback when operating the knob dial section 116. Therefore, the operator can recognize that he/she is operating the electronic device.

Further, as shown in FIG. 15 , a flat portion 116 a around the dial portion 116 in the base material 110 is not an operation area of the operation map 160 . Therefore, as shown in FIG. 3, when the operator touches the flat part 116a, the coordinates and force of the contact position are detected, but the acquisition unit 130 detects that the contact with the flat part 116a is not related to the operator's operation. It does not make a judgment and does not accept operations based on the contact. That is, the flat portion 116a of the base material 110 does not have the function that the dial portion 116 has. Further, when the operator touches the flat part 116a, the vibration generating part 150 does not vibrate the pedestal 121, that is, the base material 110 (the flat part 116a) under the control of the vibration control part 140. Therefore, by touching the flat portion 116a, the operator can recognize that the electronic device is not being operated.

(the cross key)
FIG. 16 is a perspective view of the cross key portion 117, which includes a cross key-shaped convex portion 117a and a concave portion 117b. In the operation map 160, the operation area of the cross key part 117 corresponds to the area where the convex part 117a is formed and the area where the recessed part 117b is formed. The convex portion 117a and the concave portion 117b of the cross key portion 117 each have the function of indicating a direction by pressing the tip of one of the four directions, similar to a mechanical cross key switch. When the operator presses the convex portion 117a or the concave portion 117b with a finger, the acquisition unit 130 outputs an instruction signal in the direction of the cross key corresponding to the pressed position. Note that although the convex portion 117a and the concave portion 117b have different three-dimensional shapes, they have the same function as a cross key switch. For example, if there are two types of functions to be performed on the object displayed on the display section 70, two cross keys of different shapes are lined up like the combination of the convex part 117a and the concave part 117b in FIG. 16, and the operation map is At 160, different functions are assigned to each cross key. This allows the operator to recognize which function of the cross key, convex part 117a or concave part 117b, is being operated by touching the cross key part 117 with a finger without visually checking it, thereby preventing erroneous operation. be able to. The vibration control unit 140 also controls the vibration generation unit 150 to cause the pedestal 121, that is, the base material 110 (the convex The portion 117a and the recessed portion 117) are vibrated. This allows the operator to receive haptic feedback when operating the cross key section 117. Therefore, the operator can recognize that he/she is operating the electronic device.

Further, as shown in FIG. 16, a flat portion 117c around the cross key portion 117 on the base material 110 is not an operation area of the operation map 160. Therefore, as shown in FIG. 3, when the operator touches the flat part 117c, the coordinates and force of the contact position are detected, but the acquisition unit 130 detects that the contact with the flat part 117c is not related to the operator's operation. It does not make a judgment and does not accept operations based on the contact. That is, the flat portion 117c of the base material 110 does not have the function that the cross key portion 117 has. When the operator touches the flat part 117c, the vibration generating part 150 does not vibrate the pedestal 121, that is, the base material 110 (the flat part 117c) under the control of the vibration control part 140. Therefore, by touching the flat portion 117c, the operator can recognize that the electronic device is not being operated.

(dial pointing)
FIG. 17 is a perspective view of the dial pointing section 118 having a recess 118a and an elongated cylindrical projection 118b inside the recess 118a. In the operation map 160, the operation area of the dial pointing section 118 corresponds to the area where the convex portion 118b is formed. Furthermore, there are two modes of functions that can be executed by operating the convex portion 118b of the dial pointing section 118. The first mode is a dial function like the dial section 113, and the second mode is a pointing device function. Further, as an example, the operator can switch between the first mode and the second mode by double-tapping the upper surface 118c of the convex portion 118b. Further, when the operator operates the dial pointing section 118, the vibration generating section 150 causes the pedestal 121, that is, the base material 110 (the dial pointing section 118) to vibrate under the control of the vibration control section 140. This allows the operator to receive haptic feedback when operating the dial pointing section 118. Therefore, the operator can recognize that he/she is operating the electronic device.

Further, as shown in FIG. 17, a flat portion 118d around the dial pointing section 118 on the base material 110 is not an operation area of the operation map 160. Therefore, as shown in FIG. 3, when the operator touches the flat part 118d, the coordinates and force of the contact position are detected, but the acquisition unit 130 detects that the contact with the flat part 118d is not related to the operator's operation. No judgment is made and no operation is accepted due to the contact. That is, the flat portion 118d of the base material 110 does not have the dial function that the dial pointing portion 118 has. When the operator touches the flat part 118d, the vibration generating part 150 does not vibrate the pedestal 121, that is, the base material 110 (the flat part 118d) under the control of the vibration control part 140. Therefore, by touching the flat portion 118d, the operator can recognize that the electronic device is not being operated.

In the first mode, similarly to the dial section 113, when the operator moves the convex section 118b, the detection sensor 122 detects the moment Mz of the convex section 118b around the Zs axis, and the acquisition section 130 switches the switch. Outputs an instruction signal. In the second mode, when the operator pushes in the protrusion 118b, the detection sensor 122 detects the pushing direction of the protrusion 118b, and the acquisition unit 130 outputs an operation signal according to the direction.

Further, in the first mode, the vibration control unit 140 causes the vibration generation unit 150 to vibrate when the operator pinches the convex portion 118b or twists the convex portion 118b. Furthermore, in the second mode, the vibration control unit 140 does not cause the vibration generation unit 150 to vibrate even when the convex portion 118b is operated, just as a general pointing device does not perform force feedback.

As described above, according to the electronic device 100 of the present embodiment, by providing the operating section consisting of a convex portion, a recessed section, etc. on the base material 110, the operator can identify the operating section with his/her finger.
As a result, the operator can easily recognize which operation section is being operated without visually checking the various operation sections on the base material 110, and the operability of the electronic device 100 can be improved. can. Further, the acquisition unit 130 determines at least one of the detected force and moment based on different criteria for each function executed by the operation unit, and based on the result of the determination, the acquisition unit 130 determines the operation information of the operation unit of the operator. get.

In addition, in the operation map 160, the plane portion of the base material 110 other than the area where the operation units 111 to 114 are formed is a non-operation area. That is, on the base material, an area in which the control unit does not accept operations by the operator is provided between areas in which at least one of the convex part and the concave part is set with a different function. More specifically, at least two of the protrusions and the recesses are formed on the base material, the at least two of the protrusions and the recesses are each set with different functions, and the plane part is formed in at least two areas of the protrusions and the recesses. is formed between. Therefore, even if the operator unintentionally slips his or her finger from the operation sections 111 to 114 and touches a flat surface on the base material 110, the electronic device 100 will not accept the operation. Thereby, it is possible to avoid the risk of erroneous selection or erroneous operation of the operating unit in the electronic device 100. Further, each of the operation parts 111 to 114 formed on the base material 110 has a simple shape. Thereby, the operation parts 111 to 114 can be easily cleaned with a cloth or the like, and the hygiene of the base material 110 can be maintained.

Note that the shapes described above, the functions corresponding thereto, and the vibration methods providing haptic feedback are merely examples, and are not limited thereto.

<Second embodiment>
Next, an ultrasonic diagnostic apparatus having an electronic device according to a second embodiment will be described using FIG. 18. In addition, in the following description, the same code|symbol is attached|subjected to the same structure as 1st Embodiment, and detailed description is abbreviate|omitted.

FIG. 18 is a block diagram showing the configuration of an ultrasound diagnostic apparatus 2 according to the second embodiment. Further, as shown in FIG. 18, the electronic device 200 includes a first base material 210, a detection section 220, an acquisition section 130, a vibration control section 140, a vibration generation section 150, and a memory section 230.

The first base material 210 is attached to the pedestal 221 of the detection unit 220 so as to be replaceable with the second base material 211, as will be described later. The first base material 210 has a slide switch section 111, a slider section 112, a dial section 113, and a dial trackball section 114 arranged in the same manner as the base material 110 in FIG. Therefore, the operation map corresponding to the first base material 210 is the same as the operation map 160 in FIG. 4, and a description thereof will be omitted. Further, in the second base material 211, an operation section having the same function as the operation section arranged on the first base material 210 is arranged at a different position from the first base material 210. Furthermore, the second base material 211 has an uneven shape different from that of the operation part of the first base material 210, for example, a push switch part 115 is arranged, and the first base material 210 and the second base material 211 The uneven shape of the operating section and the position of the operating section are different. Note that each of the base materials 210 and 211 only needs to be made of a material that does not easily deform even when the operator applies force, and can be molded using a 3D printer according to the operator's hand size, handedness, and ease of use. Alternatively, it may be formed by surface treatment such as texturing.

FIG. 19 is a top view showing an example of various operation parts that the second base material 211 has. Compared to the first base material 210 shown in FIG. 2B, the position of the slider portion 212 in the second base material 211 is different. Therefore, in the second base material, at least one of the protrusions and recesses having the same function as at least one of the protrusions and recesses arranged in the first base material is located at a different position from the first base material. It is located. Further, in the second base material 211, the slide switch section 111, the dial section 113, and the dial trackball section 114 are arranged at the same positions as the respective operation sections of the first base material 210, respectively. Note that the functions of each operation section of the second base material 211 are the same as those of each operation section of the first base material 210, so a detailed description of the functions will be omitted here.

In this embodiment, the memory unit 230 stores operation maps corresponding to the respective base materials 210 and 211. As will be described later, when a base material is removed and another base material is newly attached, the acquisition section 130 acquires an operation map corresponding to the newly attached base material from the memory section 230. In this way, the acquisition unit 130 also has a function as a control unit that specifies functional information corresponding to the base material based on the characteristics of the base material detected by the detection unit. Then, for example, when the first base material is detected by the detection unit, the acquisition unit 130 specifies the functional information corresponding to the first base material, and when the second base material is detected by the detection unit, the acquisition unit 130 specifies the functional information corresponding to the first base material. , specifying functional information corresponding to the second base material.

FIG. 20 is a perspective view of the ultrasound diagnostic apparatus 2 with the first base material 210 removed. The first base material 210 is detachably attached to a pedestal 221 of the detection section 220. As shown in FIG. 20, when the first base material 210 is removed, a pedestal 221 appears visibly on the detection sensor 122 (not shown), which is a 6-axis force sensor. A magnet 223 for attaching the base materials 210 and 211 is arranged on the pedestal 221. Further, magnets or thin metal plates are also arranged on the back surfaces of the first base material 210 and the second base material 211 at positions where they can be attached to the pedestal 221. Thereby, even if the base material becomes soiled, it is easy to replace the base material, and the hygiene of each operating section of the base material can be maintained. Further, it is also possible to replace the base material with a different arrangement of the operating section and surface treatment applied to the operating section depending on the operator's hand size, handedness, and ease of use. Furthermore, the base material can be replaced with a base material to which an appropriate operation map is applied depending on the usage situation. As described above, according to the electronic device 200 of the present embodiment, by simply replacing the base material without replacing the electronic device or even the ultrasound diagnostic device, it is possible to improve the operability of the operator and quickly change the diagnosis method. This makes it possible to save time.

FIG. 21 is a flowchart of a process in which the acquisition unit 130 of the electronic device 200 executes initial settings when base material exchange is performed. In step S601, the acquisition unit 130 determines whether the measured value of −Fz, which is the pulling force in the Zs-axis direction from the six-axis force sensor that is the detection sensor 122, is greater than or equal to a first predetermined value. When the first base material 210 is attached to the pedestal 221 and the operator attempts to remove the first base material 210 from the pedestal 221, the attraction force of the magnet 223 is removed by a force that removes the first base material 210 from the pedestal 221. It becomes necessary. Therefore, the detection sensor 122 detects -Fz, which is a pulling force in the Zs-axis direction. Therefore, the first predetermined value may be set to be approximately the same as the attraction force of the magnet. When the measurement value by the detection sensor 122 is equal to or greater than the first predetermined value, the acquisition unit 130 advances the process to step S602.

In step S602, the acquisition unit 130 determines whether the measured value of +Fz, which is the pushing force in the Zs-axis direction from the detection sensor 122, is greater than or equal to a second predetermined value. When a base material other than the first base material 210, for example, a second base material 211, is attached to the pedestal 221, the second base material 211 is attracted to the pedestal 221 by the adsorption force of the magnet 223. It is attached. At this time, the detection sensor 122, which is a six-axis force sensor, detects the positive pressure and outputs it as a measured value. When the measured value by the detection sensor 122 is equal to or greater than the second predetermined value, the acquisition unit 130 advances the process to step S603.

In step S603, the acquisition unit 130 recognizes that the base material has been replaced and switches the operation of the electronic device 200 to the initial setting mode of the operation map. In the initial setting mode, the acquisition unit 130 is in a state where it has not acquired the operation map.

Next, in step S604, the acquisition unit 130 sends a signal to the display control unit 60 to switch the display of the display unit 70 to the initial setting mode. The display control unit 60 displays on the display unit 70 a display prompting the operator to perform an initial setting operation. As a specific example, the display control section 60 displays on the display section 70 a request for the operator to touch any of the operation sections of the second base material 211. Next, in step S605, the acquisition unit 130 compares the initial setting action performed by the operator in step S604 with each operation map stored in the memory unit 230, and determines whether the Identify the operation map that corresponds to the substrate being used. In this way, the acquisition unit 130 specifies functional information corresponding to the base material based on the operator's operation. The acquisition unit 130 then performs initial settings using the specified operation map.

Specifically, in step S604, the operator touches the second base material 211 attached to the pedestal 221 with a finger to perform an initial setting operation. Then, in step S605, the acquisition unit 130 acquires the point of action of the finger and the direction of force based on the initial setting motion of the operator in step S604, and performs the operation of each base material stored in the memory unit 230. Check against the map. Here, the initial setting action of the operator is an action of touching any of the operating parts of the base material with a finger. For example, the operator attaches the second base material 211 and performs an operation (initial setting operation) of sliding the slider portion 212a in FIG. 19 from end to end with a finger. The acquisition unit 130 then performs a comparison of the operation maps based on a determination as to whether or not the point of action of the finger overlaps with the operation area of each operation map stored in the memory unit.

In step S606, the acquisition unit 130 determines whether, as a result of comparing the operation maps, the initial setting operation of the operator matches the operation map of any base material stored in the memory unit. For example, when the operator slides the slider section 212a from end to end with his or her finger, the acquisition section 130 detects that when the operation area of the operation map corresponding to the second base material 211 overlaps with the point of action of the finger, It is determined that the second base material 211 is attached to the pedestal 221. On the other hand, if the operation map having the operation area that overlaps with the point of action of the finger is not stored in the memory unit, the acquisition unit 130 returns the process to step S604 and controls the display control unit 60 to display the operation map on the display unit 70. Displays a message asking the user to perform the initial settings again. Note that if the same convex or concave parts are placed in the same position on different base materials and they match other operation maps, the position of the operation part used for the initial setting operation may be the same as that of the other base material. It is best to avoid overlapping the position of .

In step S607, the acquisition unit 130 acquires from the memory unit 230 an operation map that matches the base material attached to the pedestal 221. The acquisition unit 130 then ends the initial setting mode and ends the processing of this flowchart.

As explained above, by storing operation maps corresponding to each of a plurality of base materials in the memory section, an appropriate operation map is applied to the base material attached when the base material is replaced. As a result, it is possible to replace the base material with a base material that has been subjected to the arrangement, shape, surface treatment, etc. of the operation part suitable for each operator, and to apply an appropriate operation map to the replaced base material. Therefore, according to the electronic device according to the present embodiment, it is possible to improve the operability of the operating section of the base material by the operator. Further, even if the base material becomes soiled, it can be easily replaced, and the hygiene of the base material can be maintained. Also, for example, even if the software applied to an ultrasound diagnostic device is updated and the operating method is changed, the operating method can be changed by preparing a new base material and operation map without replacing the entire device. Appropriate operation can be performed even with That is, by replacing the base material of the electronic device, it is possible to respond to changes in the design of the ultrasonic diagnostic device at low cost.

<Third embodiment>
Next, an ultrasonic diagnostic apparatus having an electronic device according to a third embodiment will be described using FIG. 22. In addition, in the following description, the same code|symbol is attached|subjected to the same structure as 1st Embodiment, and detailed description is abbreviate|omitted. FIG. 22 is a block diagram showing the configuration of the ultrasonic diagnostic apparatus 3 according to this embodiment. As shown in FIG. 22, the electronic device 300 includes a base material 110, a detection section 120, an acquisition section 130, a vibration control section 140, a vibration generation section 150, and an operator detection section 310.

The operator detection unit 310 is a pressure-sensitive sensor as a contact detection unit provided separately from the detection unit 120, and includes a sensor that detects contact or proximity of the operator. The operator detection unit 310 is arranged on the base material at a position close to at least one of the protrusions and the recesses. When the operator detection unit 310 detects contact or proximity of the operator, it sends a signal to the detection sensor 122 of the detection unit 120 to start operation detection. Then, the detection sensor 122 starts detecting the force acting on the base material 110.

FIG. 23 is a perspective view of an ultrasound diagnostic apparatus 3 configured by an electronic device 300 including an operator detection section 310. The base material 110 of the ultrasonic diagnostic apparatus 3 is provided with an operator detection section 310 under the dial trackball section 114, and the operator detection section 310 also functions as a palm rest. For example, the operator detection unit 310 is provided with a pressure-sensitive sensor (not shown), and when an operator places his or her wrist on the operator detection unit 310 in order to operate the base material 110, the pressure-sensitive sensor of the operator detection unit 310 is activated. A sensor detects pressure. When the operator detection unit 310 detects pressure, it sends a signal to start detecting the operation to the detection sensor 122, and the detection sensor 122 detects the force acting on the base material. On the other hand, when the pressure-sensitive sensor does not detect pressure, the detection sensor 122 does not detect the force acting on the base material 110, and therefore the electronic device 300 does not receive an operation by the operator. In this way, the acquisition unit 130, as a control unit, enables the operator to operate on at least one of the convex portion and the concave portion of the base material when the contact detection unit detects contact with or proximity to the operator. .

For example, when the operator places his or her wrist on the operator detection unit 310 and operates the slide switch unit 111, the operator detection unit 310 detects contact or proximity of the operator. accepts operations. The slide function of the slide switch section 111 becomes effective, and, for example, it is possible to start and stop transmission of ultrasound waves. Furthermore, when the operator places his/her wrist on the operator detection section 310 and operates the slide switch section 111, under the control of the vibration control section 140, the vibration generation section 150 detects the cradle 121, that is, the base material 110 (the slide vibrate the switch section 111). Thereby, the operator can receive force feedback when operating the slide switch section 111. Therefore, the operator can recognize that he/she is operating the electronic device.

Further, for example, if the operator operates the slide switch unit 111 without placing the wrist on the operator detection unit 310, the operator detection unit 310 does not detect contact or proximity of the operator, and therefore the electronic device 300 does not accept operator operations. The sliding function of the slide switch unit 111 is disabled, and, for example, it is impossible to start or stop transmission of ultrasound waves. Further, when the operator operates the slide switch section 111 without placing the palm of the hand on the operator detection section 310, the vibration generation section 150 is controlled by the vibration control section 140 to move to the pedestal 121, that is, the base material 110 (slide). Do not vibrate the switch section 111). Therefore, the operator can recognize that the electronic device is not being operated.

Similarly, for example, when the operator places his palm on the operator detection unit 310 and operates the slider unit 112, the operator detection unit 310 detects the contact or proximity of the operator, so the electronic device 300 Accepts operations from the operator. The adjustment function by the slider section 112 becomes effective, and, for example, gain adjustment of an ultrasound image can be performed. Further, when the operator places his/her wrist on the operator detection section 310 and operates the slider section 112, under the control of the vibration control section 140, the vibration generation section 150 detects the pedestal 121, that is, the base material 110 (the slider section 112) to vibrate. This allows the operator to receive haptic feedback when operating the slider section 112. Therefore, the operator can recognize that he/she is operating the electronic device.

Further, for example, if the operator operates the slider section 112 without placing the wrist on the operator detection section 310, the operator detection section 310 does not detect the contact or proximity of the operator, so the electronic device 300 Operator operations are not accepted. The adjustment function by the slider section 112 is disabled, and, for example, gain adjustment of an ultrasound image cannot be performed. Further, when the operator operates the slider section 112 without placing the wrist on the operator detection section 310, the vibration generation section 150 is controlled by the vibration control section 140 to move to the pedestal 121, that is, the base material 110 (slider section 112) do not vibrate. Therefore, the operator can recognize that the electronic device is not being operated.

Similarly, for example, when the operator places his palm on the operator detection unit 310 and operates the dial unit 113, the operator detection unit 310 detects contact or proximity of the operator, so the electronic device 300 Accepts operations from the operator. The changing function by the dial section 113 becomes effective, and for example, the gain of the amplifier of the transmitting/receiving section 10 can be changed. Further, when the operator places the palm of his hand on the operator detection unit 310 and operates the dial unit 113, the vibration generation unit 150 is controlled by the vibration control unit 140 to generate the cradle 121, that is, the base material 110 113) to vibrate. Thereby, the operator can receive haptic feedback when operating the dial section 113. Therefore, the operator can recognize that he/she is operating the electronic device.

Further, for example, if the operator operates the dial section 113 without placing the wrist on the operator detection section 310, the operator detection section 310 does not detect the contact or proximity of the operator, so the electronic device 300 Operator operations are not accepted. The changing function by the dial section 113 is disabled, and, for example, the gain of the amplifier of the transmitting/receiving section 10 cannot be changed. Further, when the operator operates the dial section 113 without placing the wrist on the operator detection section 310, the vibration generation section 150 is controlled by the vibration control section 140 to move to the pedestal 121, that is, the base material 110 (the dial section 113) do not vibrate. Therefore, the operator can recognize that the electronic device is not being operated.

Similarly, for example, when the operator places the wrist on the operator detection unit 310 and operates the dial trackball unit 114, the operator detection unit 310 detects the contact or proximity of the operator to the electronic device. 300 accepts an operation by an operator. The changing function by the dial trackball unit 114 is enabled, and for example, the size of the displayed image can be changed. Furthermore, when the operator places his or her palm on the operator detection section 310 and operates the dial trackball section 114, the vibration generation section 150 is controlled by the vibration control section 140 to generate a vibrate the dial trackball section 114). This allows the operator to receive haptic feedback when operating the dial trackball section 114. Therefore, the operator can recognize that he/she is operating the electronic device.

Further, for example, if the operator operates the dial trackball section 114 without placing the wrist on the operator detection section 310, the operator detection section 310 does not detect the contact or proximity of the operator, so the electronic device 300 does not accept operations by the operator. The changing function by the dial trackball unit 114 is disabled, and, for example, the size of the displayed image cannot be changed. Further, when the operator operates the dial trackball section 114 without placing the wrist on the operator detection section 310, the vibration generation section 150 is moved to the pedestal 121, that is, the base material 110 ( Do not vibrate the dial trackball section 114). Therefore, the operator can recognize that the electronic device is not being operated.

Similarly, for example, when the operator places his or her wrist on the operator detection unit 310 and operates the push switch unit 115, the operator detection unit 310 detects contact or proximity of the operator to the electronic device 300. accepts operations from the operator. The switching function by the push switch unit 115 is enabled, and for example, a function executed by the electronic device 300 can be switched ON/OFF. Furthermore, when the operator places his or her palm on the operator detection section 310 and operates the push switch section 115, the vibration generation section 150 is activated by the cradle 121, that is, the base material 110 (push switch section 115) under the control of the vibration control section 140. vibrate the switch section 115). This allows the operator to receive haptic feedback when operating the push switch section 115. Therefore, the operator can recognize that he/she is operating the electronic device.

Further, for example, if the operator operates the push switch unit 115 without placing the wrist on the operator detection unit 310, the operator detection unit 310 does not detect contact or proximity of the operator, and therefore the electronic device 300 does not accept operator operations. The switching function by the push switch unit 115 is disabled, and, for example, it is not possible to switch ON/OFF a function executed by the electronic device 300. Further, when the operator operates the push switch section 115 without placing the wrist on the operator detection section 310, the vibration generation section 150 is controlled by the vibration control section 140 to Do not vibrate the switch section 115). Therefore, the operator can recognize that the electronic device is not being operated.

Similarly, for example, when the operator places his or her palm on the operator detection unit 310 and operates the knob dial unit 116, the operator detection unit 310 detects contact or proximity of the operator to the electronic device 300. accepts operations from the operator. The switching function of the knob dial unit 116 is enabled, and for example, a switch in the electronic device 300 can be changed. Furthermore, when the operator places his or her wrist on the operator detection section 310 and operates the knob dial section 116, the vibration generation section 150 is controlled by the vibration control section 140 to generate a vibrate the dial part 116). This allows the operator to receive haptic feedback when operating the knob dial section 116. Therefore, the operator can recognize that he/she is operating the electronic device.

Further, for example, if the operator operates the knob dial section 116 without placing the wrist on the operator detection section 310, the operator detection section 310 does not detect contact or proximity of the operator. does not accept operator operations. The switching function by the knob dial section 116 is disabled, and, for example, it is impossible to switch a switch in the electronic device 300. Further, when the operator operates the knob dial section 116 without placing the wrist on the operator detection section 310, the vibration generation section 150 is moved to the pedestal 121, that is, the base material 110 (knob dial section 116) under the control of the vibration control section 140. Do not vibrate the dial part 116). Therefore, the operator can recognize that the electronic device is not being operated.

Similarly, for example, when the operator places his palm on the operator detection section 310 and operates the cross key section 117, the operator detection section 310 detects contact or proximity of the operator to the electronic device 300. accepts operations from the operator. The cross key switch function of the cross key section 117 is enabled, and, for example, the object displayed on the display section 70 can be operated. Further, when the operator places the palm of his hand on the operator detection unit 310 and operates the cross key unit 117, the vibration generating unit 150 is controlled by the vibration control unit 140 to vibrate the key part 117). This allows the operator to receive haptic feedback when operating the cross key section 117. Therefore, the operator can recognize that he/she is operating the electronic device.

Further, for example, if the operator operates the cross key section 117 without placing the wrist on the operator detection section 310, the operator detection section 310 does not detect contact or proximity of the operator. does not accept operator operations. The cross key switch function of the cross key section 117 is disabled, and, for example, the object displayed on the display section 70 cannot be operated. Further, when the operator operates the cross key section 117 without placing the wrist on the operator detection section 310, the vibration generating section 150 is moved to the pedestal 121, that is, the base material 110 (cross Do not vibrate the key part 117). Therefore, the operator can recognize that the electronic device is not being operated.

Similarly, for example, when the operator places his palm on the operator detection unit 310 and operates the dial pointing unit 118, the operator detection unit 310 detects contact or proximity of the operator to the electronic device 300. accepts operations from the operator. The dial function by the dial pointing unit 118 and the function of the pointing device are enabled, and for example, a switch in the electronic device 300 can be changed. Furthermore, when the operator places his or her palm on the operator detection section 310 and operates the dial pointing section 118, under the control of the vibration control section 140, the vibration generation section 150 is activated to the pedestal 121, that is, the base material 110 The pointing unit 118) is vibrated. This allows the operator to receive haptic feedback when operating the dial pointing section 118. Therefore, the operator can recognize that he/she is operating the electronic device.

Further, for example, if the operator operates the dial pointing section 118 without placing the wrist on the operator detection section 310, the operator detection section 310 does not detect contact or proximity of the operator. does not accept operator operations. The dial function of the dial pointing unit 118 and the function of the pointing device are disabled, and, for example, switching in the electronic device 300 cannot be performed.

In this way, the operator detection unit 310 functions as a contact detection unit that detects contact with or proximity to the operator accompanying an operation of at least one of the convex portion and the concave portion by the operator. As a result, even if the operator unintentionally touches the operating section of the base material 110, if the operator detection section 310 does not detect the contact or proximity of the operator, the operation by the operating section will not be accepted. It prevents operator errors and enables reliable operation. Note that the operator detection unit 310 is not limited to detecting the pressure of the operator's operating hand using a pressure sensor, but also detects touch using an infrared sensor that detects the presence of the operator's operating hand using infrared rays or static electricity. It may also be a non-contact human sensor such as a sensor.

The portion 150 does not vibrate the pedestal 121, that is, the base material 110 (flat portion 119). Therefore, the operator can recognize that the electronic device is not being operated.
