Abstract

PURPOSE:To resolve the trouble and inconvenience of work to a user by unconditionally ejecting a recording medium to the second eject tray, which has not the stapling function, by an ejection control means after image recording if a detecting means detects that the designation of the size of the recording medium to be ejected is not decided. CONSTITUTION:When the user depresses a copy start key, a controller discriminates whether the stapling mode is set or not; and if this mode is not set, the sorting tray ejection mode is set, and a flapper 501 is so switched that recorded papers can be ejected to sorting trays 515. After the copying operation is terminated, the control is returned to a main routine. If it is discriminated that the stapling mode is set,the designation of the stapling processing is ignored to eject recorded papers to sorting trays 515 when an unfixed-form cassette or manual insertion is selected. When a fixed-form cassette is elected, recorded papers are ejected to a stapling tray 507.

Description

[Detailed description of the invention] [Industrial use 'J? The present invention relates to an image recording apparatus such as a copying machine or a facsimile machine, and more particularly to an image recording apparatus having a stapling function and a sorting function.

[Prior Art] Conventionally, in this type of image recording device, in addition to the normal sorting function, there is also a stabilization function (staple) in which a U-shaped wire peg called a staple is pushed into the paper to bind it. A stapling function (stapling function) has been proposed.

This stable function is convenient because it allows image recording and bookbinding (document binding) to be performed at the same time.

[Problems to be Solved by the Invention] However, in conventional devices of this kind, when specifying an irregular size paper feed cassette or manual paper feed, and specifying stapling processing (paper binding processing), image recording is not possible. (For example, copying) becomes impossible, which is inconvenient to the user.

In view of the above-mentioned points, the present invention allows image recording when a non-standard size paper feed cassette or manual paper feed is specified and stable processing is specified, and the recorded image is subjected to stable processing. To provide an image recording device which eliminates the troublesomeness and inconvenience of the user's work by sorting and discharging the images onto a tray without performing any sorting.

[Means for Solving the Problems] In order to achieve this object, the present invention includes a first output tray that has a stapling function for stably binding recorded recording media, and a second output tray that does not have a stapling function. An ejection tray, a detection means for detecting that the specification of the size of the recording medium to be ejected is uncertain, and an ejection control for unconditionally ejecting the recording medium to be ejected to a second ejection tray in response to detection by the detection means. It is characterized by comprising means.

[Function] The present invention provides an image recording apparatus that includes a first ejection tray that has a stapling function for stably binding ejected recorded recording media, and a second ejection tray that does not have the stapling function. In this case, when the detection means detects that the designation of the recording size to be ejected is uncertain, the ejection control means unconditionally applies the stapling function to the recording medium after recording the image even if stapling is specified. Eject to a second ejection tray that does not have a

In F300, 301 is a stacking tray on which originals are set. Document size detection sensors 3Q2 and 303 are provided at a predetermined interval in the direction perpendicular to the paper surface of the document. The size of the document in the width direction depends on whether both sensors 302 and 303 are detecting the document, or only one sensor 303 (assuming that sensor 303 is located at the back of the paper) is detecting the document. This can be determined by checking whether there are any. Note that by increasing the number of sensors of this type, the size can be determined more accurately. Further, the lengthwise size can be determined based on the time period during which the sensor 303 (or 302) detects the document.

In addition, in this RDF 300, the document sent from the stacking tray 301 through the sheet path 304 to the exposure surface is sent through the sheet pulse 305, so that it is returned to the stacking tray 303.

The recorded paper discharged to the stable tray 507 is regulated in width by a width baffle plate 509 for each part of the specified number of sheets, and the width is regulated by a width baffle plate 509,
The documents are Q-stitched and dropped onto the stacker tray 513.

That is, in the finisher 500, when the stable mode is selected by the stable key described later, the paper ejection flapper 501 is turned on and the recorded paper is ejected to the stable tray 507 via the bus 505, and the specified number of sheets is When this is reached, the width baffle plate 509 and the stapler 511 are turned on in response to an instruction from the main body 10o, and the recorded sheets are stapled with a stapler. Thereafter, the stabilized paper is dropped onto the stacker tray 513. By repeating this operation, a plurality of recorded documents that are collated and stably bound are completed.

Furthermore, when stable processing is not selected, the paper ejection flapper 501 is turned off and the sorting is switched to the side, and the recorded paper passes through the bus 5Q3 and is sorted into the tray 515.

(2) Operation Example Next, the operation of the embodiment of the present invention shown in FIG. 2 will be explained with reference to the flowchart shown in FIG.

When the user presses, for example, the staple key 625 in FIG. 3 to enter the stapling mode, selects an irregular cassette or manual feed with the cassette selection key 611, and then presses the copy start key 604, the control procedure shown in FIG. 5 is started. Ru.

First, it is determined whether or not the stapling mode is selected. If the mode is not the stapling mode (step S1), the sorting mode is set to tray ejecting mode, and the flapper 501 is activated so that the recorded paper (copied paper) can be ejected to the sorting tray 515. Sorting is switched to the tray side path 503 (step S3).

Next, the copying operation as described above in FIG. 2 is performed (step S4). It is determined whether or not the copying has been completed, and when it has been completed (step S5), this process is ended and the process returns to the main routine (not shown).

When it is determined in step Sl that the mode is stable,
Proceeding to step S2, it is determined whether or not a regular cassette is selected, and the selection of an irregular cassette or manual feed (
In other words, when the cassette is undefined (the cassette is undefined), the process moves to step S3 as in the case described above, and the copying operation is performed in the tray discharge mode for sorting (steps 54 and 5).

In other words, if the user specifies an irregular size cassette or manual paper feed and specifies stable processing, the stable processing specification is ignored and the copying operation is performed and the recorded paper is sorted into the tray 515. to be discharged. At this time, it is also possible to cause the sorting tray 515 to perform a sorting operation (a so-called swinging operation).

On the other hand, when the stable mode is selected and a regular cassette is selected, an affirmative determination is made in step S2, and
Proceeding to step S6, the stable tray discharge mode is entered, and the flapper 501 is switched to the stable tray side path 505 so that the recorded paper can be discharged to the stable tray 507. Next, a copying operation is performed (step S7).
), it is determined whether or not the i-copying is completed, and after the copying is completed (step S8), the stapler 511 is operated to staple the plurality of recorded sheets on the stable tray 507, and the stapler tray 513 Step S9),
Return to the main routine (not shown).

[Effects of the Invention] As explained above, according to the present invention, when a non-standard size paper feed cassette or manual paper feed is specified and stable processing is specified, the stable processing specification is ignored. Since the image recording is permitted and the recorded images are sorted and discharged onto the tray as they are without being subjected to stable processing, the user's trouble and inconvenience can be eliminated.
