Specification

Input operation device

Technical field

The present invention relates to an input operation device for input operation of an input operation member, and more particularly, to an input operation device used for a switching operation of a display image on an image display device.

Background art

[0002] At present, a so-called CT (Computed) is used as an image capturing apparatus for capturing image data of a plurality of continuous tomographic images from a human body.

Tomography) scanner and MRI (Magnetic

Resonance Imaging) devices are used in medical practice, and various image display devices for displaying the image data have been developed.

[0003] Such an image display device is realized by, for example, installing dedicated application software on a personal computer, and can sequentially display a plurality of pieces of image data stored as series data on a display. . However, in a general personal computer, an input operation is performed using a keyboard or a mouse on which input keys such as alphabets are arranged, so that the versatility is good, but the operability is not good.

[0004] Therefore, the image display device proposed by the present applicant includes a dedicated input operation device, and the input operation device includes an input operation member that is slidable in the front-rear direction. In this image display device, when the input operation member is slid in the front-rear direction, the image data displayed on the display is sequentially switched in response to the sliding operation, so that the image data of a plurality of continuous slice images can be easily viewed. can do.

[0005] In particular, in the above image display device, when the input operation member is slightly slid from the initial position, the image data is switched and displayed at a low speed, and when the input operation member is greatly slid, the image data is switched and displayed at a high speed. Therefore, the switching speed of the image data can be freely and intuitively adjusted.

However, with the structure in which the input operation member is slid in the front-rear direction as described above, it is difficult to automatically return the input operation member from which the manual operation has been released to the initial position. is there. Therefore, when a plurality of image data to be displayed are sequentially switched, it is difficult to stop the image switching at the moment when the desired image data is displayed.

[0007] As an input operation device that can solve such a problem, there is a product using a so-called sea source switch. In such an input operation device, an input operation member that is elongated in the front-rear direction is pivotally supported in the front-rear direction at substantially the center, and the initial operation is performed by the repulsive force of an input member such as a spring. It is urged to the position.

[0008] When such an input operation device is applied to the above-described image display device, image data can be switched and displayed in the front-rear direction by operating the input operation member in the front-rear direction. Then, since the input operation member from which the manual operation has been released is automatically returned to the initial position, it is possible to switch and display the image data and immediately stop the image data at a desired position.

[0009] However, such a sea source switch can only perform the function of individually detecting the presence or absence of an input operation in the front-rear direction, so that the speed of switching display of image data on the image display device cannot be adjusted. Therefore, in order to adjust the switching speed of the image data by the input operation device using the sea source switch, it is necessary to arrange a volume switch or the like dedicated to adjusting the switching speed separately from the sea source switch.

[0010] In this case, the occupied area of the device becomes large, and the user needs to manually operate two input operation members at once, which is not preferable. At present, there are various proposals for the input operation device as described above (for example, see Patent Documents 1 and 2).

Patent document 1: JP 2003-084910A

Patent Document 2: JP-A-2003-132766

Disclosure of the invention

Problems to be solved by the invention

[0011] For example, in the input operation device of Patent Document 1 described above, an input operation to the front, rear, left, and right is detected by using an existing switching element that detects inclination to the front, rear, left, and right. Furthermore, by supporting the switching element rotatably in the left-right direction, variable speed analog input and the like are possible.

When this input operation device is used for an image display device, for example, the input operation member By tilting in the direction, the display images are switched back and forth one by one, and by rotating the input operation member left and right in this state, the display images are continuously switched at a variable speed. However, in this case, since the input operation for single-sheet switching and the continuous switching are different, intuitive input operation is difficult.

[0013] Furthermore, when the above-described input operation device is used for an image display device, for example, by tilting the input operation member left and right in a state where a plurality of series data are displayed in parallel in the left and right direction, From the plurality of series data displayed in parallel, the processing target of front / rear switching is set to be switched. However, a switching element that detects tilting forward, backward, left and right is expensive because of its complicated structure, and its durability is not good.

[0014] Further, in the input operation device of Patent Document 2 described above, a plurality of switching elements that detect pressing are arranged before and after the input operation member that is swingable in the front-rear direction. Detects input operation to the computer in multiple stages. When this input operation device is used for an image display device, for example, the display image is switched back and forth one by one by tilting the input operation member in the front-back direction to turn on the first switching element. The display image is continuously switched by tilting the operation member to turn on the second switching element.

[0015] However, in this input operation device, at least four switching elements are required to detect the two-stage input operation in the front-rear direction as described above. Furthermore, in the input operation device described above, the input operation member cannot be operated in the left-right direction, and in order to enable this, it is necessary to further add a switching element.

The present invention has been made in view of the above-described problems, and does not require an expensive switching element or the like for detecting tilting to the front, rear, left, and right. It is an object of the present invention to provide an input operation device capable of detecting an input operation in a plurality of stages in the front-back direction.

Means for solving the problem

[0017] The input operation device of the present invention includes an input operation member, a member support mechanism, a member urging mechanism, a front switch, a left switch, a rear switch, and a right switch. A multi-step input operation and an input operation in the left-right direction are received. [0018] In the first input operation device of the present invention, the input operation member has at least a central front portion, a left front portion, a central rear portion, and a right rear portion formed below, and the member support mechanism includes: The operating member is swingably supported in the front-rear and left-right directions, and the member biasing mechanism biases the input operating member supported in the front-rear and left-right directions to the center. The front switch is located at a position facing the center front portion of the input operation member with a downward force, and is turned on by being pressed by an upward force, and the left switch is located below the left front portion of the input operation member. Is placed at a position opposite to and is turned on by being pressed by an upward force. The rear switch is arranged at a position opposing the central rear portion of the input operation member with a downward force, and is turned on by being pressed by the upward force, and the right switch is directed downward with the right rear portion of the input operation member. It is placed at the position and the upward force is pressed to be turned on.

In the second input operation device of the present invention, the input operation member has at least a central front portion, a right front portion, a central rear portion, and a left rear portion formed below, and the input operation member is operated by the right switch. Is located at a position opposing the right front portion of the input operation member with a downward force, and is turned on by being pressed from above, and the left switch opposes the left rear portion of the input operation member from below. It is placed at the position and the upward force is pressed to be turned on.

Therefore, in the input operation device of the present invention, the left switch is turned on when the input operation member is tilted to the left, and the right switch is turned on when the input operation member is tilted to the right. Therefore, an input operation in the left-right direction is detected. When the input operation member is tilted forward, the front switch is turned on and the left switch is turned on, and when the input operation member is tilted backward, the rear switch is turned on and the right switch is turned on. Since the switch is turned on, a multi-step input operation in the front-rear direction is also detected.

[0021] The various means referred to in the present invention may be formed so as to realize their functions. For example, dedicated hardware for performing predetermined functions, and predetermined functions are provided by a computer program. The data processing device can be realized as a predetermined function realized in the data processing device by a computer program, a combination thereof, or the like.

[0022] Also, various constituent elements referred to in the present invention are such that a plurality of constituent elements that do not need to be individually independent are formed as one member, and one constituent element is another constituent element. It is also possible that some of the constituent elements overlap with some of the other constituent elements.

Further, in the present invention, front-rear, left-right, up-down and up-and-down directions are defined, but this is defined for the sake of convenience in order to simply explain the relative relationship of the constituent elements of the present invention, and In this case, the directions at the time of manufacture and use are not limited.

The invention's effect

[0024] In the input operation device of the present invention, the left switch is turned on when the input operation member is tilted to the left, and the right switch is turned on when the input operation member is tilted to the right. When the force operating member is tilted forward, the front switch is turned on and the left switch is turned on, and when the input operating member is tilted backward, the rear switch is turned on and the right switch is turned on. By inputting ON, it is possible to detect input operation in the left-right direction and multi-stage input operation in the front-rear direction without using four switching elements with a simple configuration that detects only pressing. it can.

Switching is set as the switching target.

[0067] For this reason, in the image display device 300 of the present embodiment, the input / output operation of the joystick 122 in a state where a plurality of image data are displayed side by side selects the processing target of front / rear switching. In addition to selecting one from multiple image data that are displayed in parallel as objects, you can also select all of the multiple image data. [Effects of Embodiment]

In the image display device 300 of the present embodiment, the image data of the displayed series data can be variously operated by inputting the joystick 122 of the input operation device 100 as described above. In particular, since the joystick 122 can be operated in two steps in the front-back direction, the image data of the series data can be switched one by one in the front-rear direction as well as continuously, and these switching operations are intuitive. Can be performed.

[0069] Further, since the joystick 122 can be input-operated in the left-right direction, the processing target can be intuitively selected even when a plurality of image data are displayed in parallel in the left-right direction. In addition, since the joystick 122 can be input in two steps downward, display operations such as image data enlargement processing and enlargement cancellation can be performed intuitively.

[0070] In the input operation device 100 of the image display device 300 of the present embodiment, as described above, the two-stage input operation in the front-rear direction, the input operation in the left-right direction, and the two-stage input operation in the downward direction are performed as described above. Only four switches 141-144 are needed to realize it. For this reason, the structure is simple, the number of parts is reduced, and the size and weight are small and the productivity is good. Since the switches 141 to 144 are also turned on by the elastic member 130 of the input operation member 120, the input operation can be smoothly performed in two steps in the front-rear direction and the downward direction.

[Modification of Embodiment]

The present invention is not limited to the above-described embodiment, and allows various modifications without departing from the scope of the invention. For example, in the above embodiment, the input operation member 120 is formed with a center front portion 131, a right front portion 132, a center rear portion 133, and a left rear portion 134, and switches 141 to 144 are respectively provided at positions facing each other. It is illustrated that they are arranged. However, the input operation member has a central front portion, a left front portion, a central rear portion, and a right rear portion, and each of the switches 141 to 144 may be disposed at a position facing each of them. Yes (not shown).

Further, in the above embodiment, the center front portion 131, the right front portion 132, the center rear portion 133, and the left rear portion 134 of the input operation member 120 are formed by one elastic member 130 separate from the cover member 121. Although it has been illustrated that it is formed, it is also possible that such a central front portion and the like are individually formed of an elastic member, or formed integrally with a cover member (not shown). . More In the above-described embodiment, the joystick 122 is formed on the upper surface of the input operation member 120 in the form of a body.For example, the upper surface of the input operation member is formed in a curved concave shape suitable for manual operation. It is also possible (not shown).

Further, in the above-described embodiment, a force that exemplifies that each of the switches 141 to 144 is constituted by a pressing switch that only detects ON / OFF in a binary manner. For example, at least a part of these switches 141 to 144 is It is also possible to use a multi-stage switch that detects the pressing force in multiple stages, or an analog sensor force that detects the pressing force in an analog manner (not shown). For example, when the left switch 144 and the right switch 142 also have a multi-stage switching force, the second-stage input operation of the input operation member 120 in the front-back direction can be detected in multiple stages, so that the image data Switching can be performed at a multi-step variable speed.

[0074] Even in such a case, the first-stage input operation of the input operation member 120 in the front-rear direction can be binary-detected by the front switch 141 and the rear switch 143, so that switching of one piece of image data can be executed without any problem. can do. Further, the input operation of the input operation member 120 in the left-right direction can be detected in multiple stages, and the input operation of the second stage downward can be detected in multiple stages. A display operation can be performed.

Similarly, when the left switch 144 and the right switch 142 also have an analog sensor force, the input operation of the input operation member 120 in the second stage in the front-rear direction and the input operation in the left-right direction are performed in the downward direction. Since the input operation of the second stage can be detected in a stepless manner, the image data display operation can be executed well. Further, separately from the above-mentioned switches 141 to 144, the angle of inclination of the input operation member 120 in the front-rear direction can be analog-detected by an angle sensor (not shown).

Further, in the above embodiment, when the switches 141 to 144 are turned on by the elastic member 130 of the input operation member 120, the two-stage input operation in the front-rear direction and downward can be smoothly performed. Illustrated force For example, each of the switches 141 to 144, such as the front switch 141 and the rear switch 143, may be temporarily supported so as to be vertically displaceable (not shown). In this case, even if the input operation member does not have an elastic member, it is possible to smoothly execute a plurality of steps of input operation in the front-rear direction and downward.

Further, in the above embodiment, the input of the input operation device 100 is performed by assuming an appropriate size. Although the manual operation of the operation member 120 with a fingertip has been illustrated, for example, the input operation member 120 may be made larger and the input operation may be performed with the sole of the foot. Further, in the above-described embodiment, the image display device 300 exemplifies that the display unit 211 displays a pair of image data in the left-right direction in parallel. However, it is naturally possible to display only one image data. It is also possible to display the above image data.

Further, in the above-described embodiment, an example has been described in which image data of a plurality of series data is displayed in parallel. However, for example, a plurality of image data having different front and rear positions of one series data may be displayed in parallel. It is possible, and it is also possible to display one image data in plurals by different image processing.

In the above embodiment, the image display device 300 switches the image data displayed on the display unit 211 by one input operation device 100 of the control unit 200. It is also possible to arrange the input operation devices 100 side by side and switch a plurality of image data displayed in parallel individually.

Further, in the above-described embodiment, when the input operation member 120 of the input operation device 100 is input downward, the enlargement processing and the cancellation of the enlargement of the image data are executed. Various functions can be assigned to the downward input of the member 120 and the like. Further, in the above embodiment, a force exemplifying that the series data of the image data displayed on the image display device 100 is captured by the CT scanner 410 can be captured by an MRI apparatus (not shown).

Further, in the above-described embodiment, an example has been described in which various means are logically realized as various functions of the image display device 300 by operating the CPU 301 in accordance with a computer program stored in the RAM 304 or the like. However, it is also possible to form each of these various means as unique hardware, and it is also possible to store a part of the means as software in the RAM 304 or the like and form a part as hardware.
