CONSTITUTION:A wiring pattern 31 is formed on a metal board 1 through the intermediary of an insulator 2 to constitute a wiring board 3, and power electronic components 4 and signal electronic components 5 are surface-mounted on the wiring board 3. A part of the electronic component mounting face of the wiring board 3 is bent inward, and a connection connector 6 electrically connected to an inner wiring pattern through a lead wire is fixed to the rear of the wiring board 3 where no electronic component is mounted. By this setup, heat released from the electronic components is dissipated through the intermediary of the metal board, so that a heat dissipating plate used for each of electronic components especially power electronic components can be dispensed with, and as a result a highly dense mounting can be realized. If a device of this design is connected to a compression motor provided adjacent to it through the intermediary of a connection connector, a wiring can be sharply shortened in length, so that inductive noises can be lessened.

IPC: G03B5/00
Filed: 1991-11-22
Abstract: PURPOSE:To reduce the size of the deflection correction device by setting a large angle range for an axis of rotation in a direction where the deflection correction of a variable vertical angle prism is required much and a small angle range for an axis of rotation in the other direction wherein the correction is not required so much. CONSTITUTION:This deflection prevention device is equipped with a detecting means which detects deflection and the variable vertical angle prism 3 having the 1st and 2nd axes of rotation which are arranged in a plane nearly perpendicular to the optical axis of an objective and varied in vertical angle in mutually different directions. The angle range wherein the vertical angle is variable around the 1st axis 21 of rotation as the center of rotation and the angle range wherein the vertical angle is variable around the 2nd axis 23 of rotation as the center of rotation are made different from each other. Namely, the angle ranges wherein the deflection correction is performed need not be the same, so the angle range of the axis of rotation in the direction wherein the deflection correction is performed much is made large and the angle range of the axis of rotation in the other direction is made small. Further, the axis of rotation whose angle range is set small is arranged on an object side so as to eliminate the need for large outward size.
