Title: Separation device for transfer paper
Inventor: SHIMOZAKA HISANORI
IPC: G03G15/14
Filed: 1993-11-01
Abstract: PURPOSE:To effectively separate transfer paper without deteriorating the quality of a toner image on the transfer paper by positioning a part where an electric resistance value in the radial direction of a separation roller is maximum in a pass band after transfer. CONSTITUTION:Since the roller shaft 112 of the separation roller 110 is formed so that its diameter may be small in the center part and may be larger and larger toward both ends in the axial direction, the roller part 114 attached to the roller shaft 112 is thick in the center part and the thickness thereof is gradually decreased toward both ends in the axial direction. Therefore, the electric resistance value in the diameter direction of the roller 110 is large in the center part and is gradually decreased toward both ends in the axial direction. Then, since a destaticizing effect is low and influence exerted on the image is the smaller, the closer to the center part of the roller part 114, image quality is secured. Meanwhile the destaticizing effect is large near both ends of the roller part 114, so that the transfer paper is effectively separated from both ends.

IPC: G01B11/00
Filed: 1986-11-19
Abstract: PURPOSE:To derive exact height information by detecting the position of the center of gravity of a brightness distribution running along the direction being orthogonal to its linear direction, from a two-dimensional image by an optical sensor. CONSTITUTION:The product of brightness information A and position information B at every position of a brightness distribution of a two-dimensional image is calculated by a multiplier 81. Subsequently, the sum total of the product obtained at every position is calculated by an accumulator 82, and simultaneously, the sum total of the brightness information A at every position is calculated by the other accumulator 82. Next, the dividing a result obtained by the accumulator 82, by a result obtained by the accumulator 83, in a divider 84, a position of the center of gravity of the brightness distribution is detected. The bright distribution is symmetrical centering around a true peal position, therefore, the position of the center of gravity detected by a center-of-gravity detecting circuit 8 coincides with the peak position. Even if the noise is generated in the vicinity of the peak, its noise quantity is nearly equal to zero, comparing with the quantity of the brightness information contained in the whole brightness distribution. Accordingly, the position of the center of gravity coincides roughly with the true peak position without being influenced by a noise, therefore, exact height information is obtained.
