Abstract: PURPOSE:To simplify the anchoring of a bed and to easily take the arbitrary inclined image of an examinee by making the mount surface of the examinee of the bed freely revolvable on the axis crossing both of the body axis of the examinee and the horizontal axis, which crosses the body axis at a right angle, at a right angle. CONSTITUTION:When a bed 2 is anchored to a scanner room, a stand 4 is anchored at a predetermined position and, thereafter, the guides 3a, 3b of the bed 2 are mounted on a guide receiver 7. By this mechanism, the position of the bed 2 is prescribed and the positioning adjustment to the stand 4 becomes easy. Since the imaging of an examinee 41 is performed in such a state that the angle of inclination of a top plate 2c is added to the tilt angle of the stand 4, for example, even when the tilt variable range of the stand 4 is + or -25 deg., an inclined image inclined at this tilt angle or more can be taken. When a switch 37 is pressed in such a state that the stand 4 is set to a tilt angle of + or -0 deg. and the top plate 2c is held horizontally and an order is issued so that the inclining operation in the longitudinal direction and the tilt operation of the stand 4 are performed in connection with each other to incline a lever 31 in the left direction, the top plate 2c is inclined so that the head is lowered in the longitudinal direction while the stand 4 and the bed 2 are held to a right-angled state.

Title: Head driving device
Inventor: SAKOTA KAZUHITO
IPC: H02K33/18
Filed: 1990-06-04
Abstract: PURPOSE:To make the main body of the device thin by arranging both magnetic circuits in the state of crossing the two sides of a rectangularly plain coil on the same plane as the magnetic fields of both void parts while making a carriage plane. CONSTITUTION:When a current is supplied to a flat coil 3, the direction of the current is made inverse in counter thrust generation parts 3a. Since the magnetic fields are operated in mutually different directions at two points where the respective thrust generation parts 3a in one magnetic circuit cross the magnetic field of the magnetic circuit, thrust is generated in the same direction. This is similar in another magnetic circuit, namely, the thrust in generated in the same direction at all the four points where the thrust generation parts 3a and 3a of the coil 3 cross the respective magnetic fields of the two magnetic circuits. Since these thrusts are applied to a carriage 2, an optical head 1 is moved in an X direction together with the carriage 2. Further, since the optical head 1 is arranged at the position for the center of gravity at the central part of the carriage in this case, the optical head can be stably moved without being vibrated, and accuracy in the case of performing access can be improved.
