[Overall configuration of X-ray imaging apparatus 1]
FIG. 2 is an external view showing an embodiment of the X-ray imaging apparatus according to the present invention. Note that the X-ray imaging apparatus shown in FIG. 2 is shown without a control console 10 described later.

  In FIG. 2, the X-ray imaging apparatus 1 has a column body 2 arranged perpendicular to the floor surface, and an X-ray source apparatus 3 and an imaging system apparatus 4 supported by the column body 2. It has. The X-ray source device 3 and the image system device 4 are arranged through a connecting body 5 so as to face each other, and the X-ray source device 3 and the image system device 4 are supported by the column body 2 through the connecting body 5. Has been. The top plate 6 is supported by the column 2, and the top plate 6 is disposed between the X-ray source device 3 and the video system device 4 in a state of being close to the video system device 4. . Further, a compression cylinder 7 that protrudes or retracts as necessary is provided in the middle of the connecting body 5.

  In such a configuration, the top plate 6 on which the subject (not shown) is placed is in a top plate up / down direction A, a top plate lateral direction B, a top plate vertical direction C, and a top plate up / down direction D, respectively. It is configured to be movable. The X-ray source device 3 supported above the top plate 6 is configured to be movable in the X-ray source device rotation direction E, the X-ray source device vertical direction F, and the X-ray source device oblique insertion direction G. Yes. The compression cylinder 7 is configured to be movable in the compression cylinder insertion / retraction direction H, and is configured below the top plate 6 so as to receive a X-ray that has been irradiated from the X-ray source device 3 and passed through the subject to obtain a photographed image. The video system device 4 is configured to be movable in the video system vertical (vertical) direction I.

  The operations in the respective movement directions are performed by operations on the control console 10 described below.

[Overall configuration of control console 10]
FIG. 3 is an external view showing an embodiment of a control console 10 that is arranged separately from the above-described X-ray imaging apparatus 1 and that remotely operates the above-described parts of the X-ray imaging apparatus 1.

  The control console 10 has a table shape, and an operation panel 11 is arranged in the center of the desk top surface. As will be described later in detail, the operation panel 11 is provided for the X-ray source device 3, the image system device 4, the top plate 6, the compression cylinder 7, etc. of the X-ray imaging apparatus 1 shown in FIG. A plurality of operation devices that give various operation commands are arranged.

  When an operator (not shown) stands up toward the control console 10, both hands of the operator can be easily placed on the upper surface of the operation panel 11. This is because the operator can operate the operation panel 11 using both hands. Further, the desk surface on which the operation panel 11 is arranged is configured to be inclined so as to be lowered on the operator side, so that the operator can easily operate the operation panel 11.

  An X-ray TV monitor 12 is provided at the center of the desk surface opposite to the operator side with the operation panel 11 in between, and a touch panel EL display 13 is provided on the left side of the X-ray TV monitor 12. The interphone volume controller 14 and the small operation panel 15 are located on the right side of the X-ray television monitor 12, and the touch panel EL display 16, the television monitor adjuster 17 and the small operation panel 18 are easy to observe or operate for the operator. Are arranged as follows.

  The small operation panels 15 and 18 are mainly composed of a large number of switches. The small operation panels 15 and 18 are arranged with a relatively far distance from the operation panel 11 because the operation by the small operation panels 15 and 18 is relatively rarely linked with the operation by the operation panel 11. ing.

  Further, the control console 10 is provided with an intercom foot switch 19 and a fluoroscopic ON / OFF foot switch 20 at the lower part of the operator's foot. When these switches are operated, the operator's hands usually operate several operating devices on the operation panel 11. Therefore, the intercom foot switch 19 and the fluoroscopic ON / OFF are operated. The foot switch 20 is configured to be operated with a foot.

[Configuration of operation panel 11]
FIG. 4 is an enlarged plan view showing an embodiment of the operation panel 11.

  As described above, the operation panel 11 gives various operation commands to the X-ray source device 3, the image system device 4, the top plate 6, the compression cylinder 7 and the like of the X-ray imaging apparatus 1 shown in FIG. A plurality of operating devices to be provided are arranged. Each of these operation devices is roughly divided into a time-series operation device and a simultaneous operation device.

  The time-series operation devices are individually operated in response to operation commands sequentially given in time series in a series of operations of the top plate 6, the X-ray source device 3, the video system device 4, and the like. For example, it is arranged at the center of the operation panel or other appropriate position. In FIG. 3, for example, four operating devices 30 arranged adjacent to each other correspond to one of the time-series operating devices.

  The simultaneous operation device is given at the same time in a series of operations of the top plate 6, the X-ray source device 3, the image system device 4 and the like (the operation periods overlap even if they are not simultaneous at the start or end of the operation). For example, a lever operating device 31 that is arranged on the left side in the drawing and is made up of a left operating handle, and a lever that is arranged on the right side in the drawing and made up of a right operating handle. It is configured to be assigned to the operation device 32. The operator simultaneously operates the lever operation device 31 with the left hand and the lever operation device 33 with the right hand, so that one operation command and other operations are given to the top plate 6, the X-ray source device 3, or the video system device 4 or the like. Other operation commands can be given simultaneously.

  Further, even in the time series operation device and the simultaneous operation device, the cooperation in the operation is generally close, and on the operation panel 11, one of the other operation devices is operated while the other operation device is operated. You have to operate other controls with your hands.

  As an example of the use of the simultaneous operation device, it is known that there is an operation of performing a so-called ironing operation while pressing the stomach of the subject in the X-ray imaging apparatus 1. For example, the operation of the lever operation device 32 is performed. By operating the compression cylinder 7 to compress the stomach, which is an imaging region, and operating the lever operation unit 33, the top plate 6 is moved in the width direction to perform the ironing by the compression cylinder 7. The action is fried.

[Configuration of lever operating unit 34]
Further, a lever operating device 34 is arranged on the operation panel 11 in front of the substantially central portion, and the operation of the gripping portion of the lever operating device 34 in each direction of swinging (tilting) can be performed, for example, by the above-mentioned roof The plate 6 can be raised and lowered. As will be apparent from the following description, the top panel 6 can be configured so as to be reversely tilted by the operation of the lever operating unit 34.

  FIG. 1 is a block diagram showing an embodiment of the lever operating device 34 shown in FIG. 4, wherein FIG. 1 (a) shows a front view and FIG. 1 (b) shows a side view. FIG. 1 (c) is a front view showing a mechanism portion that is interlocked with the swing of the grip portion of the lever operating device 34. FIG.

  First, in FIG. 1A, the lever operating device 34 has a rod-shaped gripping portion 34a protruding from the surface of the operation panel 11 (indicated by a dotted line S in the figure), and the base of the gripping portion 34a is operated. It is supported in the board 11 by a support shaft 34b.

  As shown in FIG. 1 (c), the gripping portion 34a can swing (in the direction of arrow P) about the support shaft 34b, and its swing surface is located in front of the console (by the operator). It is a plane that is substantially parallel to the side surface.

  The lever operating device 34 is configured such that the gripping portion 34a can move in a range from −30 ° to + 30 °, for example, with respect to the vertical position.

  Then, as shown in FIG. 1 (c), when the gripping portion 34a is swung in one direction from 0 ° to 30 °, it is attached to the opposite side to the support shaft 34b and radiates from the support shaft 34b. The fan-shaped plate material 34c is swayed in the same direction, and the swing angle is detected by a rotation angle sensor 34d attached close to the arc portion of the fan-shaped plate material 34c. Further, when the gripping portion 34a is swung in another direction from 0 ° to −30 °, the fan-shaped plate member 34e attached on the opposite side to the support shaft 34b and radially formed from the support shaft 34b is moved in the same direction. The swing angle is detected by a rotation angle sensor 34f attached in proximity to the arc portion of the fan-shaped plate member 34e. Here, the angle detection of each of the rotation angle sensors 34d and 34f is performed so that the top plate 6 is activated and tilted in accordance with the angle.

  Further, the fan-shaped plate material 34c and the fan-shaped plate material 34e are guided by pins 34P respectively implanted in arc-shaped slits 34S formed around the support shaft 34b so that they can move in the same plane. And it is the structure connected by the contraction spring 34X in the said plane.

  For this reason, when the grip part 34a is moved away from the intermediate (0 °) position (vertical position), a feeling (so-called neutral position feeling) returned to the vertical position can be obtained.

  In the lever operating device 34 having such a configuration, a button operating device 35 is embedded inside the top of the gripping portion 34a, and the button portion 35a of the button operating device 35 is slightly opened from the surface of the gripping portion 34a. It is in a protruding state.

  Thus, the operator can press the button portion 35a of the button operation device 35 with his / her thumb while holding the grip portion 34a of the lever operation device 34 with, for example, the left hand.

  This means that the button operator 35 can be operated simultaneously by pressing the button part 35a when necessary, while operating the lever operator 34 by swinging the gripping part 34a. This means that each operation can be performed with only one hand of the operator. The fact that the above-described operations can be performed with only one hand further means that other different types of operation devices can be operated with the other hand.

  The switch operation of the button operation device 35 is configured independently of the switch operation in the lever operation device 34. That is, the operation command by the lever operating device 34 and the operation command by the button operating device 35 are made for separate operations. However, by constructing the button operator 35 by incorporating it in the lever operator 34, the operation itself by the operation command by the button operator 35 and the operation command by the lever operator 34 is a series of operations of the X-ray imaging apparatus 1. Relevant in operation. That is, for example, the function of the switch operation by the button operation trigger 35 is assigned to perform a so-called reverse tilting operation of the top plate 6.

  However, the lever operating device 34 is not limited to performing the tilting operation and the reverse tilting operation on the top plate 6 as described above. For example, in the operation of performing a so-called squeezing operation while pressing the stomach of the subject, the compression cylinder 7 is operated by operating the grip portion 34a of the lever operating unit 34 to compress the stomach as the imaging region. Alternatively, the ironing operation by the compression cylinder 7 may be performed by moving the top plate 6 in the width direction by operating a button operating device 35 that is built in the lever operating device 34.

  Further, the lever operating device described above is applied to the lever operating device 34 disposed in front of the central portion of the operation panel 11. However, the operation panel 11 may be applied to the lever operation device 31 that is arranged on the left side and includes a left operation handle. In this case, the function of the lever operating device 31 is, for example, the same as the conventional one, and a button operating device (button operation shown in FIG. (Corresponding to the container 35).

  Since the lever operating device 34 configured as described above includes the button operating device 35 in the gripping portion 34a, for example, the same function as that of the button operating device provided in the conventional operation panel 11 is provided. There is an effect that it is not necessary to arrange a button operating device (for example, indicated by a button operating device 35 ′ in FIG. 3). For this reason, the effect that the operation device which gave other functions to the part where this button operation device 35 'was arranged can be newly installed is also acquired.

  Incidentally, in the prior art, simultaneous operation of the lever operating device 34 using the button operating device 35 ′ is performed, for example, when operating with the left hand, the grip portion 34a of the lever operating device 34 is hung with the thumb and the button is operated with the ring finger. The instrument 35 'is pushed so that the left hand is supported on the operation panel 11 via the little finger, and the operation is difficult and accompanied by fatigue.

[Configuration of lever operating device 32]
FIG. 5 is a perspective view showing an embodiment of the lever operating device 32 shown in FIG. When compared with the lever operating device 34 shown in FIG. 1, the lever operating device 32 has substantially the same configuration as the operating device itself, but is slightly thicker at the gripping portion 32a.

  In this case, in the gripping portion 32a, a portion other than the top of the gripping portion 32a, and a portion of each finger of the hand when the gripping portion 32a is naturally gripped, touches the button operator 36. , 37 are incorporated by projecting the button portions 36a, 37a. In the case of FIG. 5, the button operators 36 and 37 are arranged at the portions where the tips of the ring finger and the little finger, for example, of the hand when the grasping portion 32 a is naturally grasped respectively.

  Since such a lever operating device 32 has a relatively thick gripping portion 32a, the button operating devices 36 and 37 can be attached with sufficient space on the side surface except the top of the gripping portion 32a. Based on that.

  Each operation of the button operating devices 36 and 37 can be easily performed by, for example, any of the corresponding fingers among the fingers of the hand gripping the grip portion 32a.

  In addition, in the lever operating device 32 configured as described above, another button operating device (indicated by reference numeral 38 in FIG. 5) other than the button operating devices 36, 37 and the like is provided at the top of the grip portion 32a. ) May be incorporated. The operation of the button operation unit 38 can be easily performed by the thumb among the fingers of the hand holding the grip portion 32a.

  In the lever operation device 32, for example, the video system device 4 is operated (uniaxial field of view switching) by the operation of the grip portion 32a, and for example, the so-called inch switching operation is performed by the button operation device 36, for example. Can be. The inch switching by the button operating device 36 can be performed by pressing the button portion 36a with, for example, the middle finger, and the inch switching can be stopped by releasing the middle finger from the button portion 36a.

  In this case, a light / dark indicator composed of, for example, a light-emitting diode is provided in the vicinity of the lever operation base 32, and the light / dark indicator is turned on by turning on the button operator 36. By configuring the light / dark indicator to be turned off by an off operation, the operator can obtain an effect of confirming the operation of the button operation device 36 visually.

  In the lever operating device 32, for example, by operating the button operating device 36, the top plate 6 is moved in the vertical direction, and the gripping portion 32a of the lever operating device 32 is swung in the horizontal direction. It is also possible to change the inch.

[Other examples]
In the above-described embodiment, the lever operating device is configured by incorporating a button operating device into a part of the side surface of the gripping portion, and these operations can be performed simultaneously only by the hand holding the gripping portion of the lever operating device. Is.

  However, instead of incorporating the button operation device, the lever operation device arranged on the operation panel 11 can be slightly swiveled around a vertical holding portion, and a swing operation of the holding portion of the lever operation device can be performed. In addition, the same operation as that performed on the button operation device may be performed by a turning operation.

  In other words, the lever operating device is configured to be able to turn, for example, 30 ° to the right side and, for example, 30 ° to the left side, in a plane parallel to the mounting surface to the operation panel 11, and supports turning to the right or left. The operation command may be output.

  In this case, for example, a rotary switch may be operated according to the turning of the lever operating unit and the operation command may be output by the rotary switch, and a contact switch that switches from OFF to ON at the end of the turning may be operated. The operation command may be output by a contact switch.

  Even if the lever operation device is configured in this way, the swing operation and the turning operation of the lever operation device can be simultaneously performed by an extremely easy operation in a state where the operator holds the grip portion.

  Further, the lever operating device arranged on the operation panel 11 can be moved up and down slightly in the direction of the vertical axis, and in addition to the swinging operation of the lever operating device, You may comprise so that the same operation may be performed.

  For example, a rotary switch may be operated in accordance with the movement of the lever operating unit by pressing it against the mounting surface side of the operating panel 11, and the operation command may be output by the rotary switch. A contact switch that switches from OFF to ON may be operated at the end of movement, and the operation command may be output by the contact switch. The lever operating device is configured so as to be biased upward, for example, by a spring, with respect to the mounting surface to the operation panel 11 at normal times, and the lever operating device is moved to the mounting surface side to the operating panel. By performing the operation against the urging force, the vertical movement operation can be easily performed.

  Even if the lever operation device is configured in this way, the lever operation device can be swung and moved up and down at the same time with an extremely easy operation while the operator holds the grip. .

  Further, in the configuration of each lever operating device described above, when any of the top plate, the X-ray source, and the image system device is operated by the swinging operation by the gripping portion, the swinging operation in one direction is performed. The operation may be slow and the operation may be set fast in the tilting operation in the other direction.

  Each of the embodiments described above may be used alone or in combination. This is because the effects of the respective embodiments can be achieved independently or synergistically.
