DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Field of the Invention The present invention relates to a bin connected to an image forming apparatus such as a copying machine, a printing machine, a printer, etc., for distributing sheets discharged from the image forming apparatus. The present invention relates to a sheet binding apparatus which can store and accumulate sheets in a bin and bind the sheets stored in a bin.

(B) Conventional technology In recent years, in order to remove inconvenience that sheets are dissipated when taking out sheets distributed to a plurality of bins, a sheet sorting / binding apparatus that binds sheets by bin has been devised ( See JP-A-58-220053 and JP-A-59-185355. The sheet sorting / binding apparatus includes, for example, a stapler capable of distributing sheets discharged from a copying machine to a plurality of bins, aligning the bundles, and moving a bundle of aligned sheets to a sheet placement position on the bins. Is sequentially stopped for each bin.

(C) Problems to be Solved by the Invention In the above-described sheet sorting / binding apparatus, sheets distributed to bins are stopped, but a bundle of sheets not distributed to bins, such as a document, is bound by the binding means such as the stapler. However, there is a disadvantage that the binding cannot be performed and the binding must be performed using another binding means.

In view of the above, an object of the present invention is to provide a configuration in which a manual sheet that is not distributed to a bin can be bound by the same binding means as a sheet arranged in the bin, thereby solving the above-described problem.

(D) Means for Solving the Problems The present invention has been made in view of the above circumstances,

Control means for controlling the binding means to move to the manual sheet binding portion and stop the sheet placed on the manual placement means. .

Further, the storage means is a multi-stage bin tray,
The binding means may automatically bind the sheet bundles of the bin tray in order.

Further, a guide portion for guiding the sheet may be provided in the manual placing means.

Furthermore, when the binding unit stops binding the sheet placed on the manual placement unit, the next binding stop at the manual sheet binding unit is prohibited unless the detection unit detects the absence of the sheet once. It is preferable to provide a double binding prohibiting means for controlling the binding.

In addition, an allowable amount detection unit that detects whether the number of sheets placed on the manual placement unit exceeds an allowable amount, and the sheet placed on the manual placement unit based on the detection of the allowable amount detection. It is preferable to provide an excess sheet binding prohibiting unit that controls the binding unit to prohibit the binding when the number of sheets exceeds the allowable amount.

Next, based on the detection by the binding member detection unit, a binding member detection unit that detects the presence or absence of a binding member that binds the sheet to the sheet placed on the manual insertion placement unit, and based on the detection of the binding member detection unit, It is preferable to provide a double binding prohibition unit that controls so as to prohibit the binding unit from stopping when detected.

(E) Function Based on the above-described configuration, the binding means for binding the sheet stored in the storage means when the sheet detection means detects the sheet on the manual stacking means and the binding instruction operation of the binding instruction means is performed. Can be moved to the manual sheet binding portion and the sheet placed on the manual placing means can be bound. That is, the binding unit can bind the sheet stored on the storage unit and the sheet on the manual placement unit with the binding unit.

Then, after the sheet P is stapled, if the sheet P is extracted from the manual sheet binding section 100 and no sheet absence is detected once by the manual sheet sensor S11, the next sheet stapling is prohibited. You. When it is detected by the magnetic sensor S12 whether or not stapling has already been performed, if stapling is detected (Step 2), sheet stapling is prohibited, and the sheet P Gap binding tolerance detection device
When it is detected whether or not the quantity is equal to or less than the allowable quantity by 111 (Step 4), a warning message of exceeding the allowable quantity is displayed (Step 9), and the binding of the sheet P is prohibited.

In the present embodiment, a manual sheet binding unit 100 that binds a sheet (manual sheet) inserted from the outside is stopped.
However, the present invention is not limited to this, and a sensor or the like for detecting the presence or absence of a sheet may be provided in the uppermost bin, and a sheet from the outside may be inserted and placed in the bin to stop the binding.

And control means for controlling the binding means to move to the manual sheet binding section and stop the sheet placed on the manual placing means when the sheet is detected and the binding instruction operation of the binding instruction means is performed. Therefore, a sheet that is not stored in the storage unit can be immediately bound by the same binding unit as the sheet that is stored in the storage unit.

Further, in the case of a sorter, even if some of the sheets stored in the storage means are stapled, the sheets can be re-bound very easily.

In the case where the guide portion is provided in the manual sheet binding portion, the sheet can be easily placed on the manual sheet binding portion.

Further, when the binding unit stops binding the sheet placed on the manual sheet binding unit, control is performed such that the next binding stop in the manual sheet binding unit is prohibited unless the sheet detection unit detects the absence of the sheet once. In the apparatus provided with the double binding prohibiting means, the double binding of the sheet can be prevented.

Also, an allowable amount detecting means for detecting whether or not the number of sheets placed on the manual sheet binding section exceeds the allowable amount, and the sheet mounted on the manual sheet binding section is permitted based on the detection of the allowable amount detecting means. Excess sheet binding prohibiting means that controls to prohibit binding of the binding means when the capacity is exceeded is provided to prevent binding of a bundle of sheets exceeding the allowable amount of the binding means. be able to.

Also, a case where a binding member is detected on the sheet based on the detection of the binding member detection unit that detects the presence or absence of a binding member that binds the sheet to the sheet placed on the manual sheet binding unit, and the binding member detection unit In the apparatus provided with the double binding prohibiting means for controlling the binding means to prohibit the binding, it is possible to prevent the binding member from being driven over the bound binding member.
