X-ray fluoroscopic imaging apparatus

1. An X-ray fluoroscopic imaging apparatus, comprising:

a table on which a subject is loaded;

an imaging element that irradiates an X-ray to said subject and detects the X-ray that transmits said subject and implements at least one of an X-ray fluoroscopy and an X-ray imaging, and configuring to move a table and an imaging element in a plurality of directions of movement;

wherein the X-ray fluoroscopic imaging apparatus, further comprises:

an operation element comprising a plurality of motion-axis selection switches and a plurality of direction switches that is provided separately from said plurality of motion-axis selection switches and respectively corresponds to said plurality of directions of movement and is used in common with respect to said plurality of motion-axis selection switches, so that said same plurality of direction switches are used in common both when one of said plurality of motion-axis selection switches is used and when another of said plurality of motion-axis selection switches is used;

a memory storing at least two of the plurality of directions of movement associated with the motion axis selection switch; and

a control element;

wherein said control element includes a shifting means which shifts the table and the imaging element to a mode capable of moving the table and the imaging element in at least two directions of movement stored in association with an operated the motion-axis selection switch and moving control means which moves the table and the imaging element in the direction of movement corresponding to the operated switch among a plurality of directional switches in a mode after the transition by the shifting means.

2. The X-ray fluoroscopic imaging apparatus, according to claim 1 , wherein:

said motion-axis switch provides a mode that is at least two selected from a group consisting of:

a straight-line motion-axis mode that shifts said table and said imaging element by a straight-line shifting in a direction of said motion-axis along at least one direction of a longitudinal direction of said table and a transverse direction thereof; and

a rotation motion-axis mode that shifts a relative location by a rotation-shifting relative to said motion-axis selection switch along at least one direction of a longitudinal direction of said table and said transverse direction thereof; and

said plurality of direction switches further comprise four switches including an up-direction switch, a down-direction switch, a right-direction switch, and a left-direction switch, wherein in the straight-line motion axis mode, when any of the four switches is continuously pressed, straight line motion is effected, and wherein in the rotation motion-axis mode, when any of the four switches is continuously pressed, a rotation motion is effected.

3. The X-ray fluoroscopic imaging apparatus, according to claim 2 , wherein:

said plurality of the direction switches further comprises four switches including an up-direction switch, a down-direction switch, a right-direction switch, and a left-direction switch;

wherein at least one switch pair selected from a group consisting of: one switch pair of said up-direction switch and said down-direction switch, and one switch pair of said right-direction switch and said left-direction switch shifts said relative location by a straight-line-shifting relative to the motion-axis direction along said longitudinal direction, and the other switch pair of said direction switches said relative location by a straight-line-shifting in a motion axis direction along said transverse direction, and

at least one switch pair selected from a group consisting of: said pair of said up-direction switch and said down-direction switch, and one switch pair of said right-direction switch and said left-direction switch shifts said relative location by the rotation-shifting relative to said motion-axis direction along said longitudinal direction, and the other switch pair of said direction switches shifts said relative location by a rotation-shifting relative to a motion-axis direction along said transverse direction.

4. The X-ray fluoroscopic imaging apparatus, according to claim 3 , wherein:

said shifting of said relative location is carried out by shifting said table relative to said imaging element.

5. The X-ray fluoroscopic imaging apparatus, according to claim 3 , wherein:

said control element cancels said motion-axis mode when no operation takes place for a time period following being subjected to said motion-axis mode.

6. The X-ray fluoroscopic imaging apparatus, according to claim 1 , wherein:

said control element carries out at least one of a lighting up and a blinking of at least one of said motion-axis selection switch and said plurality of the direction switches.

7. The X-ray fluoroscopic imaging apparatus, according to claim 6 , wherein:

said control element carries out said at least one of lighting one of lighting up and blinking at least one of said motion-axis selection switch and said plurality of the direction switches with a different color every motion-axis mode to one another.

8. The X-ray fluoroscopic imaging apparatus according to claim 1 , wherein:

said plurality of the direction switches are installed for every motion-axis mode and indicate at least one of a figure and a letter corresponding to said motion-axis mode is displayed.

9. The X-ray fluoroscopic imaging apparatus, according to claim 2 , further comprising:

a switch that switches a state, in which said relative location is manually shiftable, and a state, in which said relative location is shiftable by that said control element that controls a shifting mechanism based on an operation of said motion-axis selection switch and said plurality of direction switches.
