Title: Copying machine
Inventor: KUNO TAKASHI
IPC: G03G15/04
Filed: 1979-12-24
Abstract: PURPOSE: To improve uneven light by providing a means of controlling the quantity of the light irradiated to a line sensor through a lens synchronously with the revolution of a drum.  
     CONSTITUTION: A light transmission plate 32 is inserted between a lamp 4 and an original 3. The plate 32 is of a disc shape, is formed with a gear 31b at the circumferential edge of the disc and is coupled to a gear 31a revolving at the same speed as that of a rotary drum 8, so that the plate 32 is rotated at the same speed as that of the revolution of the drum 8. The transmittance of the plate 32 changes sinusoidally and is constituted of respective two faces of dark parts 32a and bright parts 32b. The plate 32 is synchronized with the revolution of the drum 8 and therefore if it is so set that when the dark part 32a of the plate 32 opposes to a lamp 4 a line sensor scans the central part, the decrease in the quantity of the peripheral light of the lens may be compensated. It is also possible to compensate the uneven light owing to the position of the light source lamp.

A portion of the vibration of high frequency low amplitude vibration is absorbed by a supporting board 8 made of a rubber resilient member while the other vibration is absorbed by the expansion/shrinkage of the film 34. When the deformation of the film 34 reaches to predetermined level, the deformation is regulated by the contact members 311, 331 to prevent the deterioration of the damping effect.

At the same time, the signal supplied from the contact B is fed to the circuit 13L. The pilot signal P is selectively superposed on the spectrum of an audio signal which undergoes FM modulation in the stereophonic, double sound and monaural modes at the outside of audible bands (0-20kHz), i.e., 25kHz and in response to the stereophonic and double sound modes. When control signals SB of double sounds are detected in a reproduction time, just one of these two signals is extracted at the output side. Furthermore, a signal obtained by adding both signals is extracted at the output side when a signal SM is detected.
