Abstract

SCANNING DEVICE WITH TWO HOLDING DEVICES. THE OPTICAL SCANNING DEVICE OF A CD-PLAYER IS CONNECTED WITH A HOLDING DEVICE SUCH, THAT THE SCANNING DEVICE OR ITS LENS ARE SHIFTABLE PARALLEL TO THE OPTICAL AXIS AND PARALLEL TO THE SURFACE OF THE RECORD. IN ORDER TO ACHIEVE AN OPTIMAL PRECISE PARALLEL GUIDING IS THE HOLDING DEVICE CONSTRUCTED OF TWO END PARTS (E), TWO INTERMEDIATE PARTS (Z) AND AT LEAST ONE MIDDLE PART (M). THE AXIS OF ROTATION OF THE JOINTS (K1). WHICH CONNECT EACH END PART (E) WITH A INTERMEDIATE PART (Z), ARE PERPENTICULAR TO THE AXIS OF ROTATION OF THE JOINTS (K2), WHICH CONNECT THE MIDDLE PART (M) ON BOTH SIDES WITH AN INTERMEDIATE PART (Z). THE HOLDING DEVICE CAN BE MADE OF ONE PIECE PLASTIC, WHICH POSSESSES AT THE POINTS OF JOINTS NICKS, SO THAT BENDING POINTS ARE FORMED,WHICH FUNCTION LIKE JOINTS.(FIG 3)
