Abstract: Kinematic parameters of a parallel kinematic machine can be estimated with high precision considering thermal displacement and error of a measuring device, in addition to deformation error caused by self-weight of each component. A DBB device is used when end effectors of a parallel kinematic mechanism machine are positioned at plural positions and in plural postures. In the DBB device, a plurality of support bars are provided with rigid balls on the both ends. One of the balls is fixed on a table and the other ball is provided with an end effector. The position, posture, and distance from a fixed position are measured and based on the measured value kinematic parameters are estimated. In estimating the kinematic parameters, any of deformation error caused by self-weight of each component, thermal displacement of each component, error of a measuring device are added for computation by linear approximation.

Abstract: Each actuator command is obtained based on kinematic parameters at step S1, loads exerted by weight of each component of a machine are calculated at step S2, and loads in the direction of axis of each actuator are obtained at step S3. Then loads in the direction of axis of each strut are decomposed into directions of axes of the first and second universal joints at step S4, the amounts of elastic deformation of each element are obtained at step S5, and the amounts of elastic deformation of each universal joint are approximately converted to displacement in the direction of axis of each actuator at step S6. Thereafter, at step S7 displacement in the direction of axis of each actuator obtained at step S5 and S6 is subtracted from each actuator command to renew each actuator command, thus the machine is controlled according to renewed each actuator command.

Abstract: A document size detecting device with the arm which folds by interlocking with the reciprocating motion of the optical system of the image forming apparatus and extends and contracts by interlocking with the reciprocating motion of the optical system. The optical sensor for detection of the document size is installed at a prescribed position of the arm and the feeder line for the light source is held. Therefore, the special mechanism for holding the feeder line is not necessary and it is possible to achieve simplified construction of the image forming apparatus. Also, because the feeder line is caused to curve along the outside of the arm at the rotating section thereof, it is possible to provide a large radius of the bent portion of the feeder line, there will be no considerably concentrated stress which is locally applied to the feeder line, therefore the life of the feeder line can be extended.
