Specific implementation mode
It is below in conjunction with the accompanying drawings, right by specific implementation mode in order to understand in order to preferably explain the utility model
The utility model is described in detail.
As shown in Figure 1,1 main body of printer is a laser printer.Its paper delivery position 11 is located at top, paper delivery direction
It is horizontal forward for paper.11 front of paper delivery position is provided with supporting plate 12, and one end of supporting plate 12 close to paper delivery position 11 is first end,
One end far from paper delivery position 11 is second end.Supporting plate 12 is smoother above.After paper is discharged from paper delivery position 11, Ke Yiping
It is taped against on supporting plate 12.
The second end of supporting plate 12 is higher than first end, because with certain inertia when paper is discharged, when second end is higher than the
When one end, paper promotes obliquely, and frictional resistance is larger, can be with fast and stable paper.First end can be flushed in fact, then
In the second end of supporting plate 12, bumping post is set.
Paper delivery position 11 and supporting plate 12 is completely covered in outer cover 2, and user cannot take the paper on supporting plate 12 across outer cover 2
, electrically operated gate 21 is set on outer cover 2.In Fig. 1, electrically operated gate 21 is set to 12 second end side of supporting plate, can also be actually above
Or side.Electrically operated gate 21 is rotatablely connected with 2 ontology of outer cover, can also be to be slidably connected.
The measurement end of pressure sensor 13 is abutted against with supporting plate 12.As shown in Figure 1, supporting plate 12 includes one section and second end water
Flat highly identical planar portions, the setting of pressure sensor 13 can be conducive to directly measure, such as be arranged at inclination in planar portions
Can be with, but also need to consider force resolution.
The detection signal of pressure sensor 13 passes to control centre.Control centre includes processing module, memory module, leads to
Interrogate module and operation module.
Can also include pulling mechanism of paper as shown in Fig. 2, further including litter decoration 3 and baffle 31.Institute's supporting plate 12 and outer cover 2 it
Between formed printing paper parking space;
Baffle 31 includes open state and closed state, is in closed state, and litter decoration 3 is separated by with printing paper parking space
From;In open state, litter decoration 3 is connected with printing paper parking space;Printing paper parking space top, which is provided with, pushes away paper machine
Structure, when baffle 31 is in open state, control centre controls pulling mechanism of paper and paper is sent into litter decoration 3.
Now it is based on the primary printing flow of the present embodiment description.
Communication module communicates to connect Terminal Server Client, or communicates to connect the communication interface on printer, such as USB jack,
Flash disk is connected in communication interface.Communication module passes to processing module by content is printed;
Printing content is first stored to memory module by processing module, while transferring individual paper weight pair stored in memory module
The threshold value answered;
Processing module calculates the corresponding number of paper of this print out task and its corresponding total threshold value, while controlling printer
Ontology prints;
As paper is once discharged from paper delivery position 11, the weight that pressure sensor 13 measures paper on supporting plate 12 becomes
Change, measuring signal is passed to by processing module by communication module;Processing module measurement of comparison signal and this print out task pair
The threshold value answered;
When number of paper is incorrect, the signal is different from the threshold value that the control centre is prefabricated, the control centre
It controls electrically operated gate 21 to be closed, it is not possible to the paper taken on the supporting plate 12;Baffle 31 is in open state, the litter decoration 3
It is connected with the outer cover 2;Processing module controls pulling mechanism of paper and paper is sent into litter decoration 3;Then control module control printing
The ontology of machine 1 prints again;
When number of paper is correct, the signal is identical as the threshold value that the control centre is prefabricated, control centre's control
Electrically operated gate 21 processed is opened, the paper that can be taken on the supporting plate 12;And baffle 31 is in closed state, litter decoration 3 and outer cover
2 are isolated;
The state of this printing can be passed to remote control terminal by communication module.
Further include display and alarm, alarm can be alarm lamp or alarm bell.When 13 measured value of pressure sensor
When not meeting threshold value, processing module controls alarm equipment alarm;Display shows printing, 1 real time print work to onsite application person
Make state.
The pressure sensor 13 of multiple and different positions can be set, different type, the weight of sized paper sheets are measured.It is corresponding
, individual weight threshold of different paper is stored in a storage module, and processing module can be transferred after receiving print out task
The corresponding paper data of this print out task, and can only receive the number of the corresponding pressure sensor of this print out task 13
According to.
Include vertical optical axis on printer 1, includes corresponding unthreaded hole, the setting that supporting plate 12 so floats on supporting plate 12
On printer 1, only supported by pressure sensor 13.Can be that several pressure sensors 13 support jointly.Supporting plate 12 adds
The weight of paper acts on pressure sensor 13, then passes to processing module processing.
Supporting plate 12 can also be other kinds of setting.For example supporting plate 12 is rotatablely connected with printer 1, pressure sensor 13
Measurement end, form lever construction at supporting plate 12 and rotation connection.Or supporting plate 12 is to be lifted on outer cover 2, is set on lifting rope
Set pulling force sensor.
Since operator can lead to the measurement variation of pressure sensor 13 during taking paper, mould is handled
It needs to be arranged in block, after the completion of printing, electrically operated gate 21 is opened, while the numerical value of pressure sensor is no longer result in electrically operated gate 21 and closes
It closes.
But in order to prevent surprisingly, elastic portion can be set in electrically operated gate 21, after elastic portion flexible deformation, electrically operated gate 21
At least part is far from 2 ontology of outer cover so that forms certain spacing between 2 ontology of electrically operated gate 21 and outer cover.
The utility model provides a kind of mechanism for preventing printer from having more paper, can be in existing laser printer, ink-jet
It is installed on the printers such as printer, prevents printer number of copies more than predetermined quantity or few.
Upper embodiment is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and this specification should not be construed as to this
The limitation of utility model.
