Claims

[Scope of utility model registration request]

A document table on which a document is placed, a document holding device that can be opened and closed to hold the document on the document table, a paper feeder that feeds transfer paper, and a document feeder that feeds the transfer paper from the paper feeder to a predetermined position. In the copying apparatus, the copying apparatus includes a registration roller that is sent out at a timing of , and a copying means that copies the document on the document table onto a transfer sheet sent out from the registration roller, and a document presser that detects an open/closed state of the document presser. means for detecting opening/closing; document detecting means disposed below the document table for optically detecting the document on the document table; and moving the document detecting means to vary the document detecting position of the document detecting means. a movement drive means, a movement detection means for detecting movement of the document detection means, a position drive means for changing the position of the registration roller, an instruction means for instructing correction of document placement, and an opening/closing detection means for the document holding means. , a detection signal from the original detecting means, and a detection signal from the movement detecting means are input, and with the original holding means in the closed state, the moving driving means rotates the original detecting means to detect the original. The placement state and size of the document on the document table are determined based on the detection signal from the device and the movement detection device, and if the document on the document table is shifted from the normal placement position, the position drive is performed. The means changes the position of the registration roller according to the misplacement of the document, and when the document on the document table deviates from the normal placement position by more than a permissible range, the instruction means changes the position of the document to correct the document placement. A copying apparatus comprising: a control means for issuing instructions.
