Abstract

PURPOSE:To indicate magnification and other necessary items as records on a part of copy paper by providing a black part on a part of a standard white board provided on an original stand, and providing an information light source at a relative position conjugate optically with the black part in relation to the position of exposure of an image carrier, and turning on and off the light source unit according to a stored program while a scanning optical system is scanning the white board. CONSTITUTION:A black colored part is provided on a part of a standard white board 2 and an information light source unit 17 is provided at a relative position conjugate with the black part in relation to the position of exposure at which it forms an image on a photosensitive drum 10. The unit 17 consists of a light emission diode array 17a and a condenser array 17b and displays information by turning on and off according to a stored program. When the information light source 17 is turned on and off by copying operation synchronizing with the start of moving of the scanning system while the scanning system passes the standard white board 2, characters, for instance magnification (x2), are formed at a position corresponding to the black part of the photosensitive drum 10, and necessary information such as magnification of copying, date, time, name etc. are displayed on the copy paper.

Description

[Detailed Description of the Invention] The present invention includes, for example, a copying machine, 7A7mm! The present invention relates to a device for imprinting copy magnification and other necessary information onto 1i1tV copy paper (transfer material).

Conventional C) Copying machine with variable magnification system 1el. When the user looks at the variable magnification display displayed on the operation panel, the user can see the magnification [up to B] just by knowing the magnification. This V-engine 5 display is a multi-purpose variable magnification system.
Particularly with copying machines that automatically change the magnification according to the document size and copy the entire contents (t), the user can copy everything on the transfer material after copying is complete. Since there are no records, there may be cases where the magnification is unknown or forgotten.

SUMMARY OF THE INVENTION In view of the above points, the present invention aims to display magnification and other reassuring information on a portion of copy paper as a record.

Below, we will explain the details of the turn. Fig. 1 1 U handling photocopy II v - example, 1rj. A manuscript table, 6 is a manuscript illumination lamp, and 4 is a reflective shade.・5 and 6 are mirrors of younger brother 1 and 2.

7 is the lens. 8, 9, 60, 4, 9-, 10 are photosensitive drums (image carriers).

9th grade running thread 6 to 6 (or manuscript table 1) Width Ro D to Eku W. The V original on the draft table is scanned and charged uniformly (photosensitive drum 1).
0, an electrostatic td image is formed by exposure C at the exposure bonding device 11o position. 7 is developed by the developing device 12, the developed image is transferred to the transfer material (copy paper) P by the transfer charger 14, and is sent to the fixing device 16 by the conveyor 15, where the toner image is formed into a rectangular layer. It is ejected onto copy paper outside the machine.

In such scanning type VVI photocopiers, a narrow standard white plate 2 is provided on the document table 1υ in the part where the leading edge of the original is positioned, and a white background is formed at the leading edge of the copy paper for copying. This makes it easy and reliable to separate the paper photosensitive drum 10 from the fixing device 16.

The above work f! , the copying machine is equipped with a variable magnification device,
0 is also known for enlarging or reducing the original size and copying it, but these are omitted from the figure because a known variable magnification device is applied.

The present invention is applicable to the copying magnification described above or other aspects such as date, time, ABI,
The name and other LD information t is to be displayed on the 1314 copy formed at the leading edge of the copy paper by the standard white board 2, and to be used as the edge.

Figure 2 is a view from the standard white plate 2t mirror 591P.
A part of the standard white board 2 shown here is
(yC direction perpendicular to the scanning direction Y) and has a certain width τ in the scanning direction Y (other colors matched to wavelengths to which the photosensitive drum is not sensitive) (t) M color portion 181c is provided. Then, a black background part 1B& is formed in the leading white part of the copy paper P in FIG. 6CL)L.

A 1W information light source unit 17 tray is provided at a gate position conjugate with the black color 18 with respect to the exposure position H at which the RA color portion 18 of oneself is imaged on the photosensitive drum 10. This unit includes, for example, a 'C diode array 17a and a collector block (5V) as shown in FIG.
The dots of the light emitting diode soys are arranged in the longitudinal direction of the standard white board 2v as shown in FIG. The information is displayed by blinking according to a pre-stored program, and the information is displayed by pressing the information@O selection Ta and the information key O on the operation panel of the copying machine.

When the information light source unit (information light source unit) 17h is flashed while the scanning system passes through the standard white plate in synchronization with the start of movement of the eP operation VC EX scanning system, the 51st magnification, for example, is displayed at the corresponding position on the black background part 18 of the photosensitive drum. A “×2” υ character is formed. It is also possible to change the light emission program of the light emitting diode array 17 to obtain the blank display shown in FIG. Therefore, it is also illegal to include obscene information such as the copy magnification, date, time, name, etc. on the copy paper.

170 information light source units emit ``mudiode door V'',
In addition to the 7ald example, liquid crystals, display tubes, etc. can also be used. Also, condensing lens XTv-17bKi-g normal lens,
Collection fiber 311 v y base'6% construction.
