In a copying machine, an original which has been once exposed to be scanned is inverted and transmitted again to an original table glass, and a sheet having one face onto which an image has been fixed is inverted and then transmitted through a transmitting path to an image forming section, whereby the top and back faces of the original are copied to the top and back faces of the sheet, respectively.

Copy machine having plural trays each tray capable of storing two

An imaging forming apparatus includes a platen on which an original is put, and a platen cover mounted to be opened or closed with respect to the platen. A plurality of reflection type photosensors are embedded in the platen cover at predetermined positions. First, a sensor circuit including photosensors is set in a first mode. When an original is put on the platen and the platen cover is closed, photosensors detect the reflection light from the original such that the CPU can determine a size of the original based upon sensor inputs from the sensor circuit. Thereafter, in order to detect opening or closing of the platen cover, the sensor circuit is set in a second mode. In the second mode, total sensitivity of a photosensor for detecting a minimum size of the original is heightened, and light emitting diodes of all photosensors are inhibited from being driven such that the photosensors can respond to only external light. In the second mode, when the platen cover is closed, since the external light that enters the photosensors becomes approximately zero, no detection signal is outputted from even the photosensor having higher total sensitivity, and therefore, it is possible to detect that the platen cover is closed.

Image forming apparatus with photosensors for detecting original size

A copy system includes a combination of a tablet and an input pen for inputting copy condition information such as a control condition and an editing condition, and a copying machine for forming a copy image in accordance with a copy condition information as inputted. An IC card insertion portions are respectively formed on the tablets and the copying machine. When the control condition, for example, a copy quantity and a copy magnification, and the editing condition, for example, an editing function and a positional data are inputted by the input pen and the tablet in the state where the IC card is loaded to the tablet, the inputted copy condition information is stored in the IC card. Thereafter, the IC card is unloaded from the tablet and inserted to the copying machine. The copy condition information is led from the inserted IC card to the copying machine. Upon an operation of a start key, a copy image of an original put on an original table is formed in accordance with the copy condition information read out from the IC card.

Copy system

An apparatus for inputting image forming condition includes a combination of a tablet and an input pen. An IC card insertion portion is formed on the tablet. In the state that an IC card is loaded to the tablet, when a control condition, for example, a copy quantity and copy magnification and/or an editing condition, for example, editing function and positional data are inputted by operating the tablet by means of the input pen, the inputted image forming condition is stored into the IC card. Thereafter, by unloading the IC card from the tablet and loading the same into a copying machine, a copying image of an original is formed by the copying machine in accordance with the image forming condition read out from the IC card.

Apparatus for inputting image forming condition

An apparatus for inputting image forming condition includes a display having item displaying portion in which a plurality of items of image forming condition for controlling image forming process are respectively displayed for each item and cursor displaying portion in which a plurality of cursors are formed so as to correspond to the respective items. A desired one of a plurality of cursors included in the cursor displaying portion is selectively displayed by a cursor key. When a given item is designated by the cursor key and a change key is operated in that state, content of that item is changed for every operations of the change key. The content lastly changed is inputted as image forming condition of that item.
