Description

The present invention relates to a switching element that is pressed in multiple stages, and more particularly to a switching element that is used in an input operation device in which an input operation member is input in multiple stages.

Currently, as an image capturing apparatus that captures image data of a plurality of continuous tomographic images from a human body, so-called CT (Computed
Tomography) scanners, MRI (Magnetic Resonance Imaging) devices, and the like are used in the medical field, and various image display devices for displaying the image data have been developed.

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

  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 the 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 correspondingly, so that the image data of a plurality of continuous tomographic images can be easily browsed. Can do.

  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 largely slid, the image is displayed at a high speed. The switching speed can be freely and intuitively adjusted.

  However, in 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 to which the manual operation has been released to the initial position. For this reason, when a plurality of displayed image data are sequentially switched, it is difficult to stop the image switching at the moment when the desired image data is displayed.

  As an input operation device that can solve such a problem, there is a product using a so-called seesaw switch. In such an input operation device, an input operation member that is elongated in the front-rear direction is pivotally supported at a substantially central position so as to be swingable in the front-rear direction. Is being energized.

  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 performing an input operation on the input operation member in the front-rear direction. Since the input operation member for which the manual operation has been released automatically returns to the initial position, it is possible to instantaneously stop the image data being switched and displayed at a desired position.

  However, since such a seesaw switch can only detect the presence / absence of an input operation in the front-rear direction, the speed of switching display of image data on the image display device cannot be adjusted. For this reason, in order to adjust the speed of switching display of image data with an input operation device using a seesaw switch, it is necessary to arrange a volume switch dedicated for adjusting the switching speed separately from the seesaw switch.

In this case, the occupied area of the apparatus is increased, and the user needs to manually operate two input operation members at a time, which is not preferable. Currently, there are various proposals for the input operation device as described above (see, for example, Patent Documents 1 and 2).
JP 2003-089410 A JP 2003-132766 A

  For example, in the input operation device of Patent Document 1 described above, an input operation in the front-rear direction is detected by using an existing switching element that detects tilting in the front-rear direction. Further, the switching element is pivotally supported so as to be rotatable in the left-right direction, thereby enabling analog input with variable speed.

  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-rear direction, and the input operation member is rotated in the left-right direction in that state. The display image is continuously switched at a variable speed. However, in this case, since the input operation is different between the single sheet switching and the continuous switching, an intuitive input operation is difficult.

  In the input operation device of Patent Document 2 described above, the input operation member in the front-rear direction of the input operation member is arranged by arranging a plurality of switching elements that detect pressing in front of and behind the input operation member that can tilt in the front-rear direction. Is detected 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-rear direction and turning on the first switching element, and further the input operation The display image is continuously switched by tilting the member and turning on the second switching element. However, in this input operation device, at least four switching elements are required to detect a two-stage input operation in the front-rear direction as described above.

  The present invention has been made in view of the above-described problems, and is a switching element capable of detecting a multi-stage input operation with a simple structure, and an input capable of detecting a multi-stage input operation in the front-rear direction with a small number of switching elements. An object is to provide an operation device and an image display device using the input operation device.

  The switching element of the present invention has a reference terminal, n detection terminals, and continuity detection means in order to detect a pressing force from above in a stepwise manner. The reference terminal is made of a material having conductivity and elasticity, and is formed in a beam shape that is bent when a predetermined pressing force is applied from above. The n detection terminals have conductivity and elasticity. The material is formed into a beam shape that bends when a predetermined pressing force is applied from above, and is sequentially arranged at a position facing the reference terminal from below. Since the continuity detecting means detects continuity with the reference terminal for each of the n detection terminals, it is detected that the reference terminal and the n detection terminals are sequentially bent by pressing.

  The input operation device of the present invention includes an input operation member, a member support mechanism, a front switch, and a rear switch in order to receive a plurality of steps of input operations in the front-rear direction. The member support mechanism supports the input operation member so as to be tiltable in the front-rear direction, and the input operation member is input-operated in the front-rear direction. The front switch includes the switching element of the present invention, and when the input operation member is tilted forward, the reference terminal is pressed from above. The rear switch includes the switching element of the present invention, and when the input operation member is tilted backward, the reference terminal is pressed from above. Therefore, in the input operation device of the present invention, when the input operation member is tilted in the front-rear direction with a plurality of stages of pressing force, the tilt operation is detected in a plurality of stages by the front / rear switch.

  A first image display device of the present invention includes the input operation device of the present invention, an image storage unit, and an image display unit, and the image storage unit includes at least one series data composed of a plurality of continuous image data. Is remembered. The image display means displays at least one image data of the stored series data, and the image switching means has the input operation member of the input operation device tilted forward stepwise and n reference terminals of the front switch. When the detection terminal is sequentially turned on, the image data is switched forward at a corresponding stepwise variable speed, and when the input operation member is tilted backward stepwise, the reference terminal of the rear switch is sequentially turned on to the n detection terminals. The image data is switched backward at the corresponding stepwise variable speed. Therefore, in the image display device of the present invention, the image data is switched in the front-rear direction at the corresponding variable speed by the stepwise tilting operation of the input operation member of the input operation device in the front-rear direction.

  In the second image display device of the present invention, the image switching means is configured to display an image each time the input operation member of the input operation device is tilted forward to a predetermined range and the reference terminal of the front switch is conducted to the first detection terminal. Each time the data is switched forward one by one, each time the input operation member is tilted backward to a predetermined range and the reference terminal of the rear switch is connected to the first detection terminal, the image data is switched backward one by one to perform the input operation. Each time the member is tilted forward from the predetermined range and the reference terminal of the front switch is connected to the m-th detection terminal, the image data is switched forward at the corresponding m-th stage variable speed. The image data is switched backward at an m-th stage variable speed each time the rear switch is tilted stepwise from a predetermined range and the reference terminal of the rear switch becomes conductive to the m-th detection terminal.

  Accordingly, in the image display device of the present invention, the image data is switched one by one in the front-rear direction by tilting the input operation member of the input operation device to the predetermined range in the front-rear direction, and the input operation member is predetermined in the front-rear direction. By performing the tilting operation stepwise from the range, the image data is switched in the front-rear direction at a corresponding variable speed.

  The various means referred to in the present invention need only be formed so as to realize the function. For example, dedicated hardware that exhibits a predetermined function, a data processing apparatus provided with a predetermined function by a computer program It can be realized as a predetermined function realized in the data processing apparatus by a computer program, a combination thereof, or the like.

  In addition, the various constituent elements referred to in the present invention do not have to be independent of each other, a plurality of constituent elements are formed as one member, and a constituent element is a part of another constituent element. It is also possible that a part of a certain component and a part of another component overlap.

  Further, in the present invention, the front-rear direction and the vertical direction are defined, but this is defined for convenience in order to briefly explain the relative relationship of the constituent elements of the invention, and is manufactured when the present invention is carried out. It does not limit the direction of time or use.

  In the switching element of the present invention, since the conduction with the reference terminal is detected for every n detection terminals, it is possible to detect that the reference terminal and the n detection terminals are sequentially bent by pressing, so that the stepwise pressing force can be detected. Can be detected with a simple structure.

Detection of input operations in a plurality of stages can be realized with a switching element having a simple structure.

  In the first image display device of the present invention, image data can be switched in the front-rear direction at a corresponding variable speed by a stepwise tilting operation of the input operation member of the input operation apparatus in the front-rear direction. Display switching can be realized with an input operation device and a switching element having a simple structure.

  In the second image display device of the present invention, the image data can be switched one by one in the front-rear direction by tilting the input operation member of the input operation device in the front-rear direction to a predetermined range. The image data can be switched in the front-rear direction at a corresponding variable speed by performing the tilting operation stepwise from the predetermined range.

  As shown in FIGS. 1 and 2, the front / rear switches 111 and 112 have a rectangular frame-shaped switch housing 113 having an upper surface and a lower surface opened. One reference terminal 115 and three detection terminals 116 are attached in order.

  These reference / detection terminals 115 and 116 are made of a material such as carbon steel having conductivity and elasticity and are formed in a beam shape elongated in the front-rear direction. For example, the front end portion and the rear end portion thereof are switch housings. 113 is slidably mounted. The reference / detection terminals 115 and 116 are formed in such a shape that the center protrudes upward from both supported ends, and bends when a predetermined pressing force is applied from above.

  The CT scanner 401 includes an image capturing mechanism 411 that is an image capturing unit and a communication unit 412 that is an image supply unit, and the image capturing mechanism 411 is a plurality of tomographic images that are continuous from a human body (not shown). The image data is captured. A plurality of image data continuously captured from one human body is accumulated as series data, and the communication unit 412 transmits data to the image display device 300.

And resources are stored as software. Such software is preinstalled in the image display apparatus 300, and data is read by the CPU 301 when the image display apparatus 300 is activated.

  As described above, when the CPU 301 reads an appropriate computer program and executes various processes, the image display apparatus 300 according to the present embodiment has an image acquisition unit 321, an image storage unit 322, and an image display as illustrated in FIG. 7. Various means such as means 323 and image switching means 324 are logically provided as various functions.

  The image acquisition unit 321 corresponds to the function of the CPU 301 recognizing the received data of the I / F unit 311 corresponding to the computer program stored in the RAM 304 and acquires series data from the CT scanner 410. The image storage unit 322 corresponds to a storage area or the like constructed in the HDD 305 so that the CPU 301 recognizes corresponding to the computer program described above, and stores the series data acquired by the image acquisition unit 321.

You can switch one by one. When continuity between the reference terminal 115 of the front switch 111 and the second detection terminal 116 is detected, the image data of the displayed series data is continuously switched forward at a low speed, and the reference terminal 115 of the rear switch 112 is switched. And the second detection terminal 116 are detected, the displayed image data is continuously switched backward at a low speed.

[Operation of the embodiment]
In the configuration as described above, the tomographic inspection method in the tomographic inspection system 400 of this embodiment will be described in order below. First, the CT scanner 410 captures image data of a plurality of continuous tomographic images from the human body of a patient (not shown), and the plurality of image data is registered in the image display device 300 as series data.

  When the series data is registered in the image display device 300 in this way, an operator (not shown) performs a predetermined operation on the control unit 200, whereby the image data of the series data is displayed on the display unit 211. When the joystick 104 of the control unit 200 is input with the image data displayed as described above, the image data displayed corresponding to the input operation is operated.

  More specifically, in the image display device 300 of the present embodiment, the joystick 104 of the input operation device 100 tilts forward at a predetermined angle with a predetermined pressure while image data of one series data is displayed on the display unit 211. Then, the reference terminal 115 of the front switch 111 that is pressed by the convex portion 105 of the input operation member 103 bends and contacts the first detection terminal 116.

  Then, since the voltage applied to the reference terminal 115 is detected from the first detection terminal 116, the image data of the series data displayed for each detection is switched forward one by one. Similarly, every time the joystick 104 is tilted backward by a predetermined angle at a predetermined pressure and the conduction between the reference terminal 115 of the rear switch 112 and the first detection terminal 116 is detected, the displayed image data is moved backward. You can switch one by one.

  When the joystick 104 of the input operation device 100 is further tilted forward at a predetermined pressure to a predetermined angle from the state as described above, the first detection terminal 116 of the front switch 111 is bent together with the reference terminal 115 to be second. It contacts the detection terminal 116. Thus, since conduction between the reference terminal 115 and the second detection terminal 116 is detected, the image data of the displayed series data is continuously switched forward at a low speed. Similarly, when the joystick 104 is tilted to a predetermined angle with a predetermined pressure and the conduction between the reference terminal 115 of the rear switch 112 and the second detection terminal 116 is detected, the image data is continuously switched backward at a low speed.

  From the state as described above, when the joystick 104 of the input operation device 100 is further tilted forward to a predetermined angle with a predetermined pressure, and conduction between the reference terminal 115 of the front switch 111 and the third detection terminal 116 is detected, The image data of the displayed series data is continuously switched forward at a high speed, and the joystick 104 is tilted to a predetermined angle with a predetermined pressure, and the conduction between the reference terminal 115 of the rear switch 112 and the third detection terminal 116 is detected. Then, the image data is continuously switched backward at a high speed.

  For this reason, in the image display apparatus 300 according to the present embodiment, each time the joystick 104 is slightly input and operated, the displayed image data is switched one by one to the front and back, and the joystick 104 is greatly input and operated by the front and back. Then, the image data displayed at a speed corresponding to the input stress and the tilt angle is continuously switched back and forth.

  Further, in the image display device 300 of the present embodiment, as shown in FIG. 8 and FIG. 9, a plurality of series data is displayed in addition to displaying one series of image data one by one on the display unit 211 as described above. The image data can be displayed in parallel in the left-right direction. For example, when series data using a contrast medium and series data not using it are captured and registered from a single patient, the image data of the pair of series data can be displayed in parallel in the left-right direction.

  In the image display device 300 according to the present embodiment, when a predetermined operation or the like is executed with the operation key 205 of the input operation device 100 in the display state as described above, input is performed from a plurality of image data displayed in parallel in the left-right direction. One to be processed by the controller device 100 is switched.

Can be executed automatically.

  In the input operation device 100 of the image display device 300 according to the present embodiment, the three-stage input operation in the front-rear direction is detected by the front / rear switches 111 and 112 as described above. It is good. In particular, in these front / rear switches 111 and 112, since the reference / detection terminals 115 and 116 serve both as electrodes and elastic bodies, the structure is simple and the productivity is good.

  Further, in the input operation device 100 of the image display device 300 according to the present embodiment, the input operation member 103 that is supported by the member shaft support mechanism 102 so as to be tiltable in the front-rear direction is the reference terminal 115 of the front / rear switches 111 and 112. Is resiliently energized in the center. Therefore, there is no need for a dedicated urging mechanism for disposing the input prompting member 103 at the center initial position, and the structure is simple and the productivity is good.

  Moreover, in the input operation device 100 of the image display device 300 of the present embodiment, the one reference terminal 115 and the first / second detection terminal 116 of the front / rear switches 111 and 112 are bent in order, so-called “ The joystick 104 can be tilted in three stages in the front-rear direction together with the “click feeling”.

  In particular, the reference / detection terminals 115 and 116 of the front / rear switches 111 and 112 are formed in a beam shape that is elongated in the front-rear direction, and the center thereof is formed in a “character shape” positioned above both ends. Therefore, the reference / detection terminals 115 and 116 that bend with “click feeling” when a predetermined pressure is applied are realized with a simple structure.

In addition, this invention is not limited to the said form, A various deformation | transformation is accept | permitted in the range which does not deviate from the summary. For example, in the above embodiment, two switching elements are mounted on the input operation device 100 as the front / rear switches 111 and 112, and it is exemplified that the input operation in the front-rear direction is detected. These switching elements are mounted as front / rear / left / right switches (not shown), and it is possible to detect an input operation to the front / rear / left / right.

  Further, in the above embodiment, when the conduction between the reference terminal 115 of the front / rear switches 111 and 112 and the first detection terminal 116 is detected, one image data is switched, and the reference terminal 115 and the second detection terminal 116 are switched. When the continuity is detected, the switching is performed at a low speed, and when the continuity between the reference terminal 115 and the third detection terminal 116 is detected, the switching is performed at a high speed.

  However, when conduction between the reference terminal 115 and the first detection terminal 116 is detected, the image data is switched at a low speed, and when conduction between the reference terminal 115 and the second detection terminal 116 is detected, the medium speed is switched. When conduction between the reference terminal 115 and the third detection terminal 116 is detected, high-speed switching is also possible.

However, for example, such a reference / detection terminal may be formed in an arc shape whose center is located above both ends (not shown).

  Furthermore, in the above embodiment, the image data of a plurality of series data is exemplified to be displayed in parallel. For example, it is also possible to display a plurality of image data having different front and rear positions of one series data in parallel. It is also possible to display one image data in a plurality of different image processes.

  Further, in the above embodiment, it is exemplified that the input operation member 103 of the input operation device 100 is manually operated with the fingertip by assuming an appropriate size. For example, the input operation member 103 is enlarged and input operation is performed with the sole of the foot. It is also possible. Furthermore, in the above embodiment, the image display device 300 is illustrated as displaying a pair of image data in parallel in the left-right direction on the display unit 211, but of course, it is possible to display only one image data. It is also possible to display the image data.

  In the above embodiment, the image data displayed by the image display device 300 on the display unit 211 is exemplified to be switched by one input operation device 100 of the control unit 200. For example, the control unit 200 has a plurality of input operation devices. It is also possible to perform switching operation for a plurality of image data displayed in parallel by arranging 100 in parallel. Further, in the above embodiment, the series data of the image data displayed on the image display device 100 is exemplified as being imaged by the CT scanner 410, but this can also be imaged by an MRI apparatus (not shown).

  Further, in the above embodiment, it is exemplified that various means are logically realized as various functions of the image display apparatus 300 by the CPU 301 operating corresponding to the computer program stored in the RAM 304 or the like. However, each of these various means can be formed as unique hardware, and a part can be stored in the RAM 304 or the like as software and a part can be formed as hardware.
