Abstract

An image forming system comprises a copying device, an area designating device for designating a specific area to be copied or not to be copied on a document, and a data conveying means for conveying to the copying device a coordinates data representative of the specific area and a mode data indicating that the specific area is to be copied or not to be copied. The area designating device is provided separately from the copying device.

Claims

1. A copying system capable of designating a copying area comprising:

(a) an area designating device including;

input means, including a transmission key switch, for inputting coordinates data of a specific area on a document and mode data specifying either said specific area is to be copied and areas other than said specific area are not to be copied or said specific area is not to be copied and said other areas are to be copied;

display means for displaying coordinate values of said coordinates data inputted into said input means;

converting means for converting said coordinates data and said mode data into a coordinates data signal and a mode data signal, respectively;

memory means for storing said coordinates data signal and said mode data signal converted by said converting means until said transmission key switch is activated; and

light signal generating means for successively transmitting a light signal obtained by further converting said coordinates data signal and said mode data signal stored in said memory means after said transmission key switch is activated; and

(b) a copying device, separately provided from said area designating device, for copying said specific area and not copying said other areas or for not copying said specific area and copying said other areas according to said coordinates data signal and said mode data signal of said light signal received from said light signal generating means, including;

a light signal receiving means for receiving said coordinates data signal and said mode data signal of the light signal successively transmitted from said light signal generating means of said area designating device; and

a preamplifier for amplifying outputs from said light signal receiving means.

2. A copying system according to claim 1, wherein said light signal is carried by infrared rays.

3. A copying system according to claim 1, wherein said light signal receiving means is an infrared rays receiving means.

4. A copying system according to claim 1, wherein said light signal generating means is an infrared ray generating means.

5. A copying system according to claim 1, wherein said area designating device further comprises first processing means for controlling the functions of the input means, display means, converting means and light signal generating means and wherein said copying device includes a separate second processing means for controlling the functions of the copying device.
