Abstract

Abstract A copier is comprised not only of an optical scanner and a paper supplying mechanism for supplying a copy paper sheet to have an image transferred thereonto, but also of numerical keys for inputting displacement values measured during an adjustment mode of operation of the copier at two magnification values such as 200% and 50% between the position of a target image with respect to a scanned original document and the position of a copied image of the target image with respect to a copy paper sheet and a control system which calculates timing values for supplying a copy paper sheet with respect to the action of the optical scanner on the basis of measured values inputted through the numerical keys, and controls the driving of the paper supplying mechanism according to a timing based on the timing values stored in a memory device.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 142 words
A copier comprising an optical scanner, paper supplying means for supplying a copy paper sheet to have an image transferred thereonto, input means for inputting displacement values measured during an adjustment mode of operation of said copier at two magnification values between the position of a target image with respect to a scanned original document and the position of a copied image of said target image with respect to a copy paper sheet, calculating and storing means for calculating timing values for determining the timing for supplying a copy paper sheet with respect to the action of said optical scanner on the basis of measured values inputted by said input means and storing said calculated timing values, and driving means for driving said paper supplying means according to a timing based on said timing values stored in said calculating and storing means.
Claim 2
Dependent Claim 142 words
A copier comprising an optical scanner, paper supplying means for supplying a copy paper sheet to have an image transferred thereonto, input means for inputting displacement values measured during an adjustment mode of operation of said copier at two magnification values between the position of a target image with respect to a scanned original document and the position of a copied image of said target image with respect to a copy paper sheet, calculating and storing means for calculating timing values for determining the timing for supplying a copy paper sheet with respect to the action of said optical scanner on the basis of measured values inputted by said input means and storing said calculated timing values, and driving means for driving said paper supplying means according to a timing based on said timing values stored in said calculating and storing means.
Claim 3
Dependent Claim 17 words
The copier of claim 1 wherein said input means include numerical keys disposed on a control panel.
Claim 4
Dependent Claim 14 words
The copier of claim 1 wherein said two magnification values are 200% and 50%.
