Abstract

PURPOSE:To attain the copying of a good quality by changing the moving distance of an original platen of a copying machine in accordance with a plate write surface copying time and an original platen placed original copying time, making the cover of a non-original placed area of a pressing plate openable and closeable by the moving force of the original platen, and forming an optical path from a plate write scanner. CONSTITUTION:In a plate write copying mode, the original platen 21 moves in the direction (a), and the part 26a of an opening/closing cover 26 supported so as to be freely rotatable by the part 24a of a pressing plate 24 is hooked by a clamping arm 10 supported by the cover 2 of a plate write scanner 1. In such a state, by turning in the direction (c) opposite to the moving direction of the original platen 21, an optical path in the plate write copying mode, and on a field lens 23 provided on a position '0', the image of a plate write surface part in a scanning position is formed by an optical system in the plate write scanner 1, and the image formed on this field lens 23 is projected to a photosensitive body 27 through the lens 28. Subsequently, in an original copying mode, the original platen 21 moves to the direction of (a) and (b), brought to an exposure scan by a lamp 29, and since a copy original is placed on original platen glass, the copying of a good quality is executed.

(Prior art) Conventionally, in devices that make it possible to copy information written on a board, the board reading method generally uses a plane scanning method using a COD sensor as a solid-state image sensor, and the recording method generally uses a thermal recording method. It is. This type of digital method not only cannot copy the calligraphic information on the board onto plain paper, but also has a slow recording speed, so it takes time to copy several other sheets, and the resulting recording density is about 6 dots/mm.
That's about it.

Therefore, a method of recording information written on a board using an electrophotographic method has recently been proposed. This type of method includes a method in which information written on a board is directly imaged on a belt or drum-shaped photoreceptor of a conventional electrophotographic copying machine, and is copied onto a plain paper transfer material using a known electrophotographic process. +l written on the board! A method in which information is once imaged on a field lens installed on a manuscript table, the image is formed on a photoreceptor through an optical system in an electrophotographic copying machine, and then transferred to a transfer material using a known process for copying. etc.

Both methods can copy the original placed on the manuscript table and the information written on the board onto plain paper, and have improved recording density compared to conventional digital methods. When obtaining a single copy, after copying a board document once, if the transfer material obtained by the copying is used as a copy original to make a second copy, there is no wastage of time due to the copying speed.

However, in the above-mentioned conventional example, in order to form an optical path in the board copying mode, the cover of the document table pressure bonding plate is removed and the document table glass is used in an exposed state, or the document table is moved a long distance and there is no cover, etc. I had to. In addition, the space between the board scanning device and the copying device must be shielded from light to prevent the information on the board from being seen.Moreover, if there is no pressure bonding plate in the original copy mode, it is necessary to prevent light from entering the space between the board scanning device and the copying device. There was a drawback of significant image deterioration.

For example, a motor for controlling the document table 8th shift and a control motor for other copying devices may be provided separately, and the drive of the control motor may be moved to the position where the opening/closing cover is opened (Fig. 1) in response to an input signal in the board copying mode. It may be configured such that the document stand is returned to a predetermined standby position in the document copy mode upon either the end of this mode or a return signal to the document copy mode. Normally, in a one-motor type copying device, a clutch operated by motor switching is interposed in the document table drive transmission system.
The clutch may be engaged and engaged so as to perform the above motor control. This clutch can be turned on and off using a microswitch that is normally used to detect the position of the document table, and a microswitch for the board copy mode that is installed outside the microswitch that defines the reciprocating document table in the document copy mode. These signals can be used to control the reversal of the document table in each mode. In the above embodiment, the document table moving type was explained, but the present invention is a copying machine with a fixed document table, and in the board scanning mode, the document table is fixed. is released and moved to the first position, and the optical path is used by stopping the moving optical system while maintaining the imaging distance, or
The optical system mirror described above may be used for the optical path inside the copying machine.

(Effect) As explained above, in a position where both the information written on the board and the original placed on the platen of the copying machine can be copied, both the information written on the board and the original placed on the platen can be copied. By changing the moving distance of the document table of the copying device, the cover of the non-document placement area of the pressure bonding plate can be opened and closed by the movement force of the document table, and by forming an optical path compared to a plate scanning device, it is a simpler installation. It is now possible to copy documents on a board without the need for a light-shielding device between the board scanning device and the copying device, and even when the original is placed on the document table, the original is made of a light-transmitting material, and the original is of small size. Copying is now possible.
