Title:
PICTURE COPYING MACHINE
Document Type and Number:
Japanese Patent JP3137271
Kind Code:
B2
Abstract:
PURPOSE: To improve the noise immunity and to reduce the produced noise by accommodating a read section, a write section and a primary signal processing section into a conductive case connecting to ground and arranging the case close to the upper part of the machine main body.
CONSTITUTION: A read section 4, a write section 12 and a primary signal processing board 11, that is, a primary signal processing section 111, are arranged closely to an upper part of a machine main body 1, they are contained in a case 31 and supported. Furthermore, the sections such as the read section 4, the write section 12, and the primary signal processing section 111 are arranged to the lower part of the original platen 2 located to the uppermost location of the machine main body 1 altogether. Since the three sections are arranged concentratingly, the transmission flow of the picture signal sent among them is reduced, and even when the sections are connected electrically by a harness, the length of the harness is reduced and a radio wave noise radiating from the harness is reduced and the effect of external noise is immune.
