As shown in fig. 10, another embodiment of the present invention provides a control method for controlling the office equipment, including: acquiring a page interval time A for the printer 10 to continuously print a plurality of pages of a document; recording an actual interval time B from each output of one sheet to the output of the next sheet at the paper output port 13 of the printer 10; if the (A-B)/A is smaller than the threshold value, judging that the multi-page document is being printed, and if the (A-B)/A is larger than or equal to the threshold value, judging that the printing of the multi-page document is finished; after one copy of the plural-page document is printed, the plural-page document is bound by the binding section 22 of the binding machine 20, and then the bound plural-page document is output by the conveying section 23 of the binding machine 20.

In this embodiment, the binding machine 20 first obtains the interval a between the continuous printing of the multiple pages of documents by the printer 10 according to the printing condition of the printer 10, and determines whether the printing of one of the multiple pages of documents is completed according to the relationship between a and B, so as to determine whether to bind, thereby improving the automation degree of the office equipment.

Specifically, acquiring the page interval time a during which the printer 10 continuously prints a multi-page document includes: the rotation of the paper feeding roller at the paper outlet 13 of the printer 10 is monitored by a sensor, when all the first sheets of paper are output from the paper outlet 13, the paper feeding roller stops rotating, and a timer inside the stapler 20 starts to record time, and when the paper feeding roller starts to rotate again, the time recorded by the timer is a, and a is less than 2 seconds.

In this embodiment, the second sensor 26 is used to monitor the rotation of the paper feeding roller at the paper outlet 13, to obtain the page interval time a when multiple pages of documents are printed continuously, and to store the time a as a comparison with the page interval time B during actual printing, and to determine whether multiple pages of documents or multiple pages of documents are printed completely according to the relationship between a and B.

Further, the threshold is 20%, and the control method further includes: recording the number of sheets printed for each print job, and the binding section 22 does not perform the binding operation in the case where one sheet is printed for one print job; the sensor is used to detect whether or not a foreign object enters the stapling position of the stapler 20, and when the foreign object is detected, the operation of the stapling unit 22 is stopped.

Optionally, the actual office equipment shields and protects unnecessary parts, and exposed parts are reduced as much as possible.

Specifically, the stapler 20 has a learning function, the second sensor 26 monitors the rotation of the paper feeding roller at the paper outlet 13 of the printer 10 at any time, when the roller stops rotating after the first sheet of paper completely comes out of the printer 10, the timer in the stapler 20 starts to record time until the next time when the paper feeding roller at the paper outlet 13 of the printer 10 rotates again (the interval time must be within 2 seconds, if the interval time is more than one other printing task), the time interval a is defined as the page interval time (the interval is generally 1 second) when the printer 10 installed with the automatic stapler continuously prints multiple pages of documents, the interval time a exists in the device buffer of the stapler 20, and the stapler 20 disappears immediately after being powered off. If the paper is printed continuously until a certain actual interval time B and B exceeds the time interval a but the printer 10 still does not discharge the paper on time, that is, it is considered that a multi-page document is printed, at this time, the first sensor displays the detected number C of printed paper on the display screen 11, the binding machine 20 starts binding, the two electromagnetic driving portions 224 are powered on, the two electromagnetic driving portions 224 are attracted downward by the magnetic force at the same time, the second pressing plate 223 and the pressing sheet 2228 together with the second pressing plate 223 are driven to press down the staples in the staple row, so as to bind the next stack of paper into a book, and the staples penetrate through the paper to form a bend in the binding groove 234. After the binding is completed, the two electromagnetic driving portions 224 are powered off, the third resilient member 2243 in the main body 2241 springs up the driving pin 2242 to return to the original position, and then the rotating portion 233 on the first conveying plate 231 starts to rotate for 2 seconds to remove one bound document from the office equipment, and the office equipment completes one work cycle. If the printer 10 does not discharge paper on time even though B exceeds the time interval a after printing continuously until a certain actual time interval B, and C indicates that the number of printed sheets is 1, the stapler 20 defaults to single-page printing for this job, and the stapler 20 does not perform the stapling operation. The arrangement is such that the stapler 20 performs learning recording in the first power-on operation performed after connection with the printer 10, and thereafter performs stapling judgment and operation on the sheets printed by the printer 10 in conjunction with the learning recording data. The binding machine 20 can be applied to printers 10 of different hosts and different models, and the versatility of the binding machine 20 is improved.

The technical scheme has the following effects or advantages:

1. the labor intensity of workers is reduced, and the labor efficiency is improved.

2. The binding of the file can be ensured through automatic binding of the file.

3. Due to the three binding structures, the device is convenient and quick in cartridge clip type operation for loading the staples.

4. The number of staples and the positions of the staples can be selected as needed, and it is only necessary to determine whether or not the staples are mounted in three binding structures.

5. Because the binding machine has a learning function, the binding machine has a learning process every time when being electrified and operated, the binding machine can ensure that the printer can bind immediately after outputting a complete file, and the function can be self-adaptive to the matching use process of different hosts and printers with different models.
