DETAILED DESCRIPTION OF THE INVENTION [0030] Referring now to the drawings, wherein like reference numerals designate the same or corresponding parts throughout the several views, a first embodiment of an X-ray diagnosis apparatus is explained with reference to FIG. 4, which is a side view of the X-ray diagnosis apparatus. The X-ray diagnosis apparatus includes a plate 1 on which a patient P is put, a bed body 2 which holds and moves the plate 1, an X-ray tube 3 which irradiates X-ray to the patient P, an X-ray detector 4 which detects the X-ray penetrated through the patient P, and a supporting unit 5 which supports and moves the X-ray tube 3 and the X-ray detector 4. The X-ray diagnosis apparatus further includes an operation panel 6 used for operating drive of the bed body 2 or the supporting unit 5, a monitor 7 which displays the image created by an image processor based on the detection result from the X-ray detector 4, a high-voltage generation unit which applies high-voltage to the X-ray tube 3, and a controller which controls the drive of the bed body 2 or the supporting unit 5. The image processor, the high-voltage and the controller will be explained below. [0031] The bed body 2 moves the plate 1 in a tilt direction centering on a rotation center O of the plate 1, a vertical direction, a longitudinal direction indicated as a dotted arrow a shown in FIG. 4, and a short direction (depth direction in FIG. 4), and a rolling direction. The supporting unit 5 rotates the X-ray tube 3 and the X-ray detector 4 according to the angle of the tilt direction centering on an interested part Q, such that the X-ray is irradiated in several directions. In more detail, the supporting unit 5 moves in a longitudinal rotation direction indicated as an arrow b shown in FIG. 4, in a slide rotation direction that is on a vertical face, and in a main rotation direction that is on a horizontal face. The supporting unit 5 further moves in the horizontal direction indicated as an arrow c in FIG. 4, when the patient P is put on the plate 1. [0032] A block diagram of electric composition of the X-ray diagnosis apparatus is shown in FIG. 5. The X-ray high-voltage unit 8 is connected to the X-ray tube 3, and the X-ray detector 4 is connected to the image processor 9 which creates an image based on the detection result from the X-ray detector 4. Moreover, the image processor 9 is connected to the monitor 7 which displays the image created by the image processor 9. The control circuit 10 which controls each part is connected to the bed body 2, the supporting unit 5, the operation panel 6, the X-ray high-voltage unit 8, and the image processor 9. The control circuit 10 controls the value of high-voltage applied to the X-ray tube 3 from the X-ray high-voltage unit 8, the various image processings performed by the image processor 9, and the drive of the bed body 2 or the supporting unit 5 based on control signals from the operation panel 6. [0033] The operation panel 6 and the plate 1 of the X-ray diagnosis apparatus is explained with reference to FIG. 6. The operation panel 6 includes an attachment part 6 b attachable to a guide rail 11 which is an example of an attachment unit. The guide rail is placed on a side of the plate 1. The operation panel 6 may be attachable to each side of the plate 1. For example, when the plate 1 is rectangle, the operation panel 6 may be attachable on four side parts. [0034] Furthermore, as shown in FIG. 7, a transmitting part 6 c that transmits the information related to the operation of the operation panel 6 (hereinafter called as SW signal) on infrared rays, is placed on a face of the attachment part 6 b of the operation panel 6. The guide rail 11 includes a receiving part 11 a that receives the infrared rays from the operation panel 6 and is placed on a corresponding face to the transmitting part 6 c. In the first embodiment, since the signal is transmitted and received by the infrared rays and a conventional signal cable can be omitted, it is easy to handle the operation panel 6. And it is also easy to attach or detach the operation panel 6. As shown in FIG. 6, the guide rail 11 may preferably include several equally positioned receiving parts 11 a in order that the operation panel 6 is attachable to a whole part of the guide rail 11 of the plate 1. The receiving part 11 a may be positioned inside of the guide rail 11 instead of outside of the guide rail 11. For instance, as shown in FIG. 8, an internal space is established in the guide rail 11, and the receiving parts 11 a is positioned at the end of the guide rail 11. The transmitting part 6 c sticks out to the internal space. As shown in FIG. 9, the receiving part 11 a can receive the infrared rays, even if the operation panel 6 is attached to any parts of the guide rail 11. In such a structure the receiving part 11 a can be provided with respect to each guide rail, and it is possible to reduce to influence of dust, exogenous material, and outside light, etc. However, in order to shorten the communication distance between the receiving part 11 a and the transmitting part 6 c to establish accurate infrared communication, it is preferable that the receiving part 11 a is positioned outside of the guide rail 11. Either structure can be employed. [0035] When a wireless communication, such as the infrared communication and not a cable communication, is used, it may be performed to check establishment of the communication or to check error of the SW signal, in order to detect break of various switch systems in the operation panel 6, incorrect recognition due to noise during communication, and/or other communication fault. For this reason, the control circuit 10 may control the receiving part 11 a to perform the communication several times to confirm the SW signal, and if the communication is not appropriately established, a safety action, such as stop of drive of the bed body 2 and the supporting unit 5, may be implemented. [0036] A detail of processing, in the control circuit 10, for matching an operation direction of the operation panel 6 and a driving direction of the bed body 2 and the supporting unit 5 according to attachment position of the operation panel 6 attached to the side of the plate 1, is explained. In FIG. 10 and FIG. 11, the infrared communication between the operation panel 6 and plate 1 is shown. The transmitting part 6 c of the operation panel 6 includes a signal transmitting circuit 60 which transmits the SW signal. Receiving parts 11 a through 11 d that are placed at the guide rails on sides of the plate 1, such as head, right, left and leg sides, respectively include signal receiving circuits 110 a through 110 d that receive the SW signal transmitted from the signal transmitting circuit 60. The signal receiving circuits 110 a-110 d of the plate 1 are connected to the control circuit 10 in the bed body 2, and the control circuit 10 is connected to a bed drive part 2 a for driving the bed body 2 and a supporting unit drive part 5 a for driving the supporting unit 5 supporting the X-ray tube 3 and the X-ray detector 4. [0037] The control circuit 10 detects an attachment state of the operation panel 6, as shown in FIG. 11. For example, the control circuit 10 includes a position detecting part 10 a that detects the attachment position of the operation panel 6 by detecting which signal receiving circuit receives the SW signal, and includes a direction detecting part 10 b that detects the operation direction of an operation lever 6 a based on the SW signal from the operation panel 6. The control circuit 10 further includes a memory part 10 c that stores information of relation between the drive direction of the bed drive part 2 a and the supporting unit drive part 5 a and the operation direction of the operation lever 6 a, and includes a drive control part 10 d determines the drive direction based on the position of the operation panel 6 and the operation direction of an operation lever 6 a, referring to the information of the relation stored in the memory part 10 c. [0038] Operation of the control circuit 10 is explained with reference to FIG. 12. When the operation panel 6 is attached to one of the guide rails 11 and the operation lever 6 a of the operation panel 6 is operated, the SW signal is generated. The position detecting part 10 a detects the attachment position of the operation panel 6 by detecting which signal receiving circuit receives the SW signal (S01). The direction detecting part 10 b detects the operation direction of the operation lever 6 a based on the SW signal from one of the signal receiving circuits 110 a through 110 d (S02). The drive control part 10 d determines the drive direction based on the position of the operation panel 6 and the operation direction of an operation lever 6 a, referring to the information of the relation stored in the memory part 10 c (S03). The bed body 2 and the supporting unit 5 are moved based on the determined drive direction (S04). For example, when the position of the operation panel 6 is changed from the right side to the left side in the short direction of the plate 1, the drive directions of the bed drive part 2 a and the supporting unit drive part 5 a are reversed in both short and longitudinal directions. In another example, when the position of the operation panel 6 is changed from the down side to the left side, the drive directions of the bed drive part 2 a and the supporting unit drive part 5 a are reversed with respect to each other. [0039] As described above, in the first embodiment, since infrared communication is performed between the operation panel 6 and the plate 1, it is possible to omit the conventional cable and it is easy for the operator to attach or detach the operation panel 6 to the plate 1. [0040] A second embodiment of an X-ray diagnosis apparatus is explained with reference to FIG. 13 through FIG. 15. To simplify the explanation, the explanation of elements of the second embodiment common with the first embodiment are omitted. In the second embodiment, in addition to the operation panel 6 which performs the infrared communication as in the first embodiment, an operation panel 6′ which performs cable communication is provided. The operation panel 6′ is connected to the control circuit 10. An operation of the communication between the operation panel 6′ and the plate1 is performed in steps S01 to S03 as shown in FIG. 15 as well as the first embodiment. In step S05, the control circuit 10′ detects an operation of the operation panel 6′. When the operation panel 6′ is not operated by the operator, the bed body 2 and the supporting unit 5 are driven based on the operation panel 6 (S06). When the operation panel 6′ is operated by the operator, the bed body 2 and the supporting unit 5 are driven by priority based on the operation panel 6′, regardless of the operation of the operation panel 6 (S07). In the second embodiment, since the operation panel 6′ can be used in case the infrared communication does not work well, safety improves. [0041] The present invention is not limited to the above embodiments, and various modifications may be made without departing from the spirit or scope of the general inventive concept. For example, not both but one of the bed body 2 and the supporting unit 5 may be driven with the operation panel 6. The plate 1 may be driven with the operation panel 6. Moreover, the operation panel 6 may be attachable only to both sides of the plate 1 not to whole sides. The operation panel 6 may be attachable to the bed body 2. The communication of the SW signal between the operation panel 6 and the plate 1 may be performed by other wireless communication methods, such as electric wave instead of the infrared communication method. The position of the operation panel 6 may be detected by a detector using GPS and earth magnetism, etc. As another example of detection of the attachment state, it may be detected whether at least one signal receiving circuit receives the SW signal. When the SW is not detected, it is determined that the operation panel 6 is not appropriately attached to the plate, and the bed body 2 and the supporting unit 5 may be stopped. Furthermore, as long as the state of the attachment is detected, a connector may be used to transmit the SW signal from the operation panel 6 to the bed body 2 instead of the infrared communication. The connector may be also used as the attachment unit instead of the guide rail 11. Moreover, a operation button may be used instead of the operation lever 6 a. [0042] Various additional modifications and variations are possible. It is therefore to be understood that within the scope of the appended claims, the present invention may be practiced differently than as specifically described herein.
