Japanese Patent Publication No. 43-29420 discloses a device in which information such as the date can be printed on recording paper using a printing roller, ■
Japanese Unexamined Patent Publication No. 53-39124 discloses a device in which a liquid crystal display element is embedded in a part of a manuscript table, and the information displayed on the liquid crystal display element is recorded on recording paper.
Publication No. 6-140368 describes a gripper that grips a document on a photosensitive drum, and a liquid crystal display section is provided on the exposed surface of the photosensitive drum, and additional information is displayed and exposed on the liquid crystal display section. All of these devices have the drawbacks of being complicated in structure, large in size, and expensive.

[Purpose of the invention]

In view of the above points, it is an object of the present invention to provide a copying device that can record additional information using a simple mechanism.

[Structure of the invention]

In order to achieve the above object, the present invention provides a copying apparatus capable of recording additional information such as a date along with document information, which is provided with means for projecting the additional information, and the projection means is projected through a convergent light transmission body. It is constructed so that it can be projected directly onto a photoreceptor drum.

〔Example〕

Next, the present invention will be described based on embodiments shown in the accompanying drawings.

In FIG. 1, 1 is a document 3 placed on a document table 2.
This is a copying apparatus that records original information on a recording paper 4, and the copying apparatus 1 records original information on a first mirror 6, a second mirror 7, and a third mirror by scanning by moving a light source 5 (or original table 2). 8. The surface of the photoreceptor drum 11 is exposed to light through a copying optical system consisting of a lens 9 and a fourth mirror 10, and due to this exposure, the charge applied to the photoreceptor drum 11 is converted into a latent image by the charging section 12, and this is converted into a latent image by the developing section 13. After the development, the image is transferred to the recording paper 4 supplied from the paper feed section 15 at the appropriate timing in the transfer section 14, and sent from the m feeding section 16 to the fixing section 17.
After fixing, the paper is ejected.

Reference numeral 20 denotes a converging light transmitting body provided between the document information exposure section a and the developing section 13 of the photosensitive drum 11 (or it may be provided between the exposure section a and the charging section 20 as shown in a dashed line); 21
is a means for projecting additional information such as a date, which is provided opposite to the upper end surface of the convergent light transmitting body 20. As shown in the second figure, the projection means 21 is provided with a pattern display section 24 capable of displaying additional information on a liquid crystal at the end of an optical path frame 23 containing a light source 22. The pattern display section 24 of the projection means 21 has its pattern portion 24a.
Since a liquid crystal display element is used in which one portion 24b is opaque and the other portion 24b is transparent, the pattern on the pattern display portion 24 is displayed on the surface of the photoreceptor drum 11 via the convergent light transmitter 20 by the light beam emitted from the light source 22. projected directly onto the

Note that the width of the projection means 21 and the convergent light transmission body 20 is large in the drawing, and when they are rotated by 90 degrees, it appears that an image cannot be formed due to the curvature of the photoreceptor drum 11.
In practice, it is possible to make the photosensitive drum 110 a size that is not affected by the curvature, and it is preferable to configure the photosensitive drum 110 so that it can be rotated in the 90° direction by a drive mechanism (not shown).

Further, the projection means 21 and the focusing transmission body 20 are configured to be movable in the axial direction of the photosensitive drum 11 together with their drive mechanism. This is so that the information projected from the projection means 21 can be recorded in accordance with the size of the recording paper 4. The projection means 21 can be moved manually or electrically, but if it is electrically moved, the reference position is set to CP.
A desired position can be selected by the number of encoder pulses generated from a motor driven by a detection signal from a sensor (not shown) that detects the size of the document placed on the document placement table 2. Bye.

Furthermore, appropriate locations on the exterior body of the copying device 1 (mainly the operation panel)
display means (not shown) capable of displaying the same content as that displayed on the display unit 24 of the additional information projection means 21;
It is preferable to provide the additional information to be recorded so that the additional information to be recorded can be checked from the outside and can be easily corrected.

Next, the operation of the above embodiment will be explained.

When copying a document with characters written parallel to its short side onto recording paper 4 of the same size, when setting the document with the short side against a scale plate (not shown), additional information is required. The projection means 21 and the focusing transmitter 20 are moved to a position determined by the document size, and the projection means 21 is set so that the direction of the pattern display section 24 is parallel to the direction of the document information. Thereafter, when the copying apparatus 1 is operated, the copying apparatus 1 exposes the original information to the surface of the photosensitive drum 11 through the copying optical system. The information projected through the rays merges and is exposed onto the surface of the photosensitive drum 11. Therefore, when the recording paper 4 is supplied to the post-development transfer section from the paper feeding section at a predetermined timing, the additional information F is recorded on the leading edge of the paper as shown in FIG. The direction is the same as that of G (shown by the horizontal line).

In addition, when copying onto recording paper 4 of the same size using a document with characters written parallel to the long side, when setting the document with the short side against the scale plate, the additional information projection means is used. 21 from the above-mentioned position to the 90° rotation position and the copying device 1 is operated, the additional information F is recorded on the recording paper 4 in the same direction as the original information G, as shown in FIG. That will happen.

Therefore, if a different size than the above is used as the original and recording paper, the projection means 21 and the focusing light transmitting body 20
All you have to do is move the position.

Other operations are the same as above.

Note that the additional information projection means 21 and the converging light transmitting body 20 shown in this embodiment are other than a copying machine.

Of course, it can also be used in recording devices such as printers that use photoreceptors.

〔Effect of the invention〕

As described above, the present invention provides a copying apparatus that is capable of recording additional information such as a date along with document information, and is provided with means for projecting the additional information.

Since the projection means is installed so as to be able to project directly onto the photoreceptor drum via the convergent light transmission body, it is advantageous in that it is possible to record additional information together with original information using a simple mechanism. It has the effect of
