Abstract

PURPOSE:To prevent misselection of a size of recording paper in the recording apparatus capable of loading plural recording bundles, by comparing a ratio of each detected size of an original and the paper with a prescribed magnification, and controlling execution of automatic recording. CONSTITUTION:A controller 200 receives information of a detected original size from the original size detector 204 of an original placing platen 203 and that from a recording paper cassette container 206, and then, it decides a ratio of a designated recording paper size to the original size. The coincidence of this ratio with the resignated magnification is checked through an operation station 206 with the controller 200 and it is controlled whether to execute automatic recording of the copying machine or not. On the other hand, when the size ratio of the recording paper to the original is out of the variable magnification range, the automatic recording mode is changed over to a manual recording mode, and it is returned to the automatic recording mode when it is ended. As a result, misselection of a recording paper size can be prevented in the recording apparatus loaded with plural sizes of recording papers, and variable power recordings can be carried out by easy operation.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a recording device in which a stack of recording sheets can be loaded at the same time, and in particular, to prevent incorrect selection of the size of recording sheets used for recording operation and to improve operability. It is designed to be multi-functional.

Conventionally, recording devices such as copying machines have become multi-functional in order to meet a wide variety of demands. With the spread of variable-magnification copying machines, it has become possible to select the desired size of recording paper by operation.
It has become possible to copy originals of different sizes onto recording paper of the same size by key operation. However, on the other hand, the number of operation keys for specifying recording operation conditions has increased significantly, making key operations extremely complicated.
Regarding multi-functionality, in general, the recording operation mode that is frequently used at the same location is overwhelmingly biased. For example, 90% of the recording operation modes are copied to All size to adjust the filing size.
In many cases, the usage of recording operation modes using recording paper of other sizes is about 10%. Therefore, /θ%
In order to improve the operability of the recording operation mode with a usage frequency of 90%, the operability of the recording operation mode with a usage frequency of 90% becomes complicated.
There were some drawbacks that could not be said to be satisfactory.

The purpose of the present invention is to eliminate the above-mentioned conventional drawbacks and to
To provide a recording device which prioritizes and automates recording operation modes with high frequency of use, makes manual operation of recording operation modes with low frequency of use, and prevents erroneous recording. It is in.

The present invention will be described in detail below with reference to the drawings.

First, FIG. 1 shows a longitudinal section of an example of the structure of the recording apparatus of the present invention. In the illustrated structural example, / is a document feeder and a mounting table! The upper document is sequentially fed by a belt r rotated by pulleys O and 7 via rollers 4Z and 5, and is ejected onto the ejection table 3. ri is the recording device main body, /θ, /
/, /, 2 and /3 are Bj, A4', respectively
3 self-recording paper cassettes in each size of 13G' and A3, l
3, /3, /≦, and /7 are means for detecting recording paper cassettes of each size. Assume that the operation unit (not shown) is equipped with an automatic recording key and an automatic recording display (not shown), and that an All-size original is fed along the mounting table λ. The document is set along the reference point/za of the platen/l by the roller ≠, j and the conveyor belt r. At this time, the rollers p and t are connected to a pulse counter (not shown) to detect the length of the transported document, and if necessary, an optical sensor or the like is installed perpendicular to the direction of transport of the document. The document size is identified by arranging the documents and detecting the widthwise dimension. With the document feeder having such a configuration, a document can be correctly set on the platen 1g, and the size of the document can be identified.

Next, the operation control means of the recording apparatus main body determines the ratio between the above-mentioned document size, for example, A3, and a preselected recording paper size, for example, AII, in the main body apparatus, for example, A37A, l.
The zoom lens Δ is moved so that the magnification m of the optical system matches I = 0.7, and when the movement is completed, the recording paper is fed from the first ha cassette // from the top in the figure. The photosensitive drum is rotated in the direction of the arrow, and the first mirror, which is a movable part of the optical system, rotates at a speed that is twice the circumferential speed of the photosensitive drum, and the second mirror n and the third mirror 3
are united, at a speed that is //2m times the circumferential speed,
Both begin to move to the right in the figure. Next, the optical image of the original is formed on the photosensitive drum at the imaging section through an optical system consisting of the first to third mirrors 2/-2 and the lens B. 2/-2J move to the positions indicated by broken lines and at the same time the exposure ends, they begin to move in the opposite direction, that is, to the left in the figure, and return to the standby position. On the other hand, the photosensitive drum is first positively charged by the charger, and when it reaches the image forming area %, it is AO charged by the AC charger IK at the same time as the document image is projected, and then the entire surface is exposed by the full surface exposure lamp 29. The photosensitive drum〃
An electrostatic latent image is formed thereon, enters the developing device 30, and is visualized. Next, the recording paper fed from A≠paper cassette // comes into close contact with the photosensitive drum, and the developed image on the photosensitive drum is transferred by the transfer charger 3/, and the recording paper after the transfer is It is peeled off from the photosensitive drum and transferred to the transport unit 3.
! The paper is guided and conveyed to the fixing device 33, and after the fixing is completed, it is taken out to the recording paper tray (3).In addition, if the photosensitive drum is used, a cleaning plate or the like pressed against the surface of the photosensitive drum is used to remove the remaining transfer material. Wipe the toner and wait for the next cycle.

The above is the basic operation of the recording device of the present invention, but the feature of the recording device of the present invention is that the image of the first draft of the detected size on recording paper of the specified size is approximately ]−f(
- The recording operation is performed by automatically setting the magnification of the document reading optical system so that it can be recorded in almost completely white by changing the magnification according to the size, and the automatic copy key and its display are still not displayed on the operation panel. By providing a function, if the ratio between the original size and the specified recording paper size, and therefore the required magnification, deviates from the predetermined variable magnification, the automatic copy operation state is canceled and the automatic recording operation is switched to manual recording operation. Furthermore, even when special recording operations are to be performed, such as recording an image of a document with margins on oversized recording paper, the automatic copying operation state can be canceled and the processing can be performed by manual recording operation. At the point. Therefore, as mentioned above, if the usage frequency is, for example, 9
The standard recording operation state of 0% or more can be automatically recorded without any operation, without malfunction, and the remaining 7θ%
By automating most of the recording operations in a multi-functional recording device, we are able to improve operability and record without any trouble. function can be achieved.
