Abstract

PURPOSE:To resolve trouble to a user for processing after ejection of purposeless papers by inhibiting the recording operation at the time of both sides recording, half folding, and stapling are designated simultaneously. CONSTITUTION:At the time of a both sides image designation (x), half folding designation (y), and stapling are simultaneously executed to an image recorder provided with a recording part (a) capable of both sides recording, a folding means (b) which folds a recorded ejected paper, and a stapling means (c) for binding, an inhibit signal is outputted through a recording control means (d) to inhibit recording to a recording medium by the recording part (a). Thus, ejection of bound and folded purposeless papers whose inside the images are recorded on is prevented, and the user is released from the trouble of exclusion of these purposeless papers.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image recording apparatus such as a copying machine or a facsimile, and 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, a staple function (staple), in which a U-shaped wire peg called a staple is pushed into the paper to bind the paper, has been used. A device with a ring function) has been proposed.

This stapling 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 this type of conventional apparatus, there is a double-sided recording designation that specifies that image information be recorded on both sides of a recording medium (for example, transfer paper), and a A half-fold specification that specifies that the medium (for example, copied paper) be folded at its center position, and a stapling specification that specifies that the paper ejected downstream is to be stolen. Even if both were specified at the same time, the recording operation was allowed and double-sided recording, half-folding, and stapling were executed sequentially, so the result was double-sided recording with double-sided binding as shown in Figure 6, which was meaningless. There is a problem in that objects are discharged onto the discharge tray, which bothers the user.

In view of the above problems, it is an object of the present invention to provide an image recording device that eliminates the user's inconvenience by prohibiting image recording when double-sided recording, half-folding, and stapling are simultaneously designated. With the goal.

[Means for Solving the Problems] In order to achieve the present object, the present invention provides a recording medium that is ejected to the ejection side of a recording unit equipped with a double-sided recording means for recording information on both sides of a recording medium in accordance with double-sided recording designation. In an image recording apparatus that includes a folding means for folding a recorded recording medium according to a half-fold designation, and a stapling means for binding the ejected recording medium according to a stapling designation, a double-sided recording designation, a half-fold designation, and a stapling designation can be simultaneously performed. The present invention is characterized in that it includes a recording control means that prohibits the recording operation in the recording section when specified.

[Operation] In the present invention, when double-sided recording designation, half-folding designation, and stapling designation are simultaneously designated, the recording control means prohibits the recording operation in the recording section.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

C, RDF (circulating document feeder) (300) IID
In F300, 301 is a stacking tray on which originals are set. Document size detection sensors 302 and 303 are provided at a predetermined interval in a 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 on the back side 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, more accurate size can be determined. Further, the lengthwise size can be determined based on the time period during which the sensor 303 (or 302) detects the document.

Further, in this RD F 300, the document sent from the stacking tray 301 to the exposure surface through the sheet bus 304 can be loaded onto the stacking tray 301 again by feeding it through the sheet pulse 305.

The recorded sheets discharged to the staple tray 507 are regulated in width by a width baffle plate 509 for each part of the specified number of sheets, stapled by a stapler 5Xl, and dropped onto a stacker tray 513.

That is, in the finisher 500, when the stapling mode is selected by the staple key described later, the paper ejection flapper 501 is turned on and the recorded paper is ejected to the staple tray 507 via the bus 505, and when the specified number of sheets is reached, The width baffle plate 509 and the stapler 511 are turned on according to instructions from the main body 100, and the recorded sheets are stapled. Thereafter, the stapled paper is dropped onto the stacker tray 513. By repeating this operation, a plurality of recorded documents that are collated and stapled are completed.

Further, when stapling processing is not selected, the paper ejection flapper 501 is turned off, the sorting is switched to the side, and the recorded paper is ejected to the sorting tray 515 through the bus 503. At this time, according to an instruction from the main body 100, recorded sheets can be stacked in well-separated sheets, shifted by 30 mm to the left and right.
