Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a business (personnel information, etc.) in which it is necessary to limit a person who takes out a printed sheet in an environment in which a printing apparatus is shared, and particularly, an output business requiring confidentiality of these. The present invention relates to a printing device used in a field where there are not so many everyday items.

[0002]

2. Description of the Related Art FIG. 6 is a diagram showing a configuration of a conventional printing system, and shows a case where two stackers are used as an example. In the figure, 1 is a computer for sending data to be printed,
A printing device 2 prints the data sent by the computer 1. Incidentally, 3a is a first stacker for accommodating a print medium discharged from the printing apparatus 2 (hereinafter, printed paper will be described as an example), and 3b
Is a second stacker that stores printed sheets ejected by the printing device 2, and which of the first stacker 3a and the second stacker 3b is used is selected by an instruction from the computer 1. Further, 4 is a printing room.

Conventionally, in the case of strictly managing printed paper, the printing apparatus 2 and the first stacker 3a and the second stacker 3b are installed in a printing chamber 4 that can be locked exclusively for operation management. ..

[0004]

Therefore, in the management of printed paper in the conventional example, it is necessary to provide a lockable room exclusively for the printing apparatus, and the cost of building and maintaining this room is a financial burden on the user. There is a problem called.

An object of the present invention is to enable printed sheets to be kept confidential with a stacker.

[0006]

In order to achieve the above object, according to the present invention, a plurality of stackers 3a for temporarily storing printed sheets printed by a printing device 2 connected to a computer 1,
In 3b ..., an ID storage circuit 31 for storing the ID data sent from the computer 1 in advance in a certain stacker 3a among the stackers 3a, 3b ..., and an ID reader provided in the stacker 3a. The ID read buffer 36 for storing the ID information input from the 35, the ID storage circuit 31 and the I
Collation circuit 32 for collating both outputs of D read buffer 36
And a door lock mechanism 34 for opening the door of the stacker 3a only when the verification results match.

Further, a plurality of stackers 3 for temporarily storing the printed sheets printed by the printing device 2 connected to the computer 1.
In a, 3b, ..., ID information is sent to a certain stacker 3a among the above-mentioned stackers 3a, 3b .. An interface control circuit 37 that outputs a door opening signal based on the determination result, and a door lock mechanism 34 that opens the door of the stacker 3a when the door opening signal is received.
And the configuration provided with.

[0008]

According to the present invention, as shown in FIG. 1, the ID data sent from the computer 1 is stored in the ID storage circuit 31, and the ID information read from the ID card 30 by the ID reader 35 is read. Store in buffer 36.

Therefore, the stored data are compared in the collation circuit 32, and the door lock mechanism 34 is opened only when the collation results match.

[0010]

Embodiments of the present invention will be described below with reference to FIGS. 1 and 3 show an embodiment of the circuit of the present invention. still,
2 shows the data stream used in the circuit of FIG. 1, and FIG. 4 shows the data stream used in the circuit of FIG. FIG. 5 shows the overall configuration of the printing system of the present invention, in which the first stacker 3a is a reader for the ID card 30.
The point that 35 is provided is different from the conventional example of FIG.

First, referring to FIG. 1 showing a first embodiment of the present invention, 1 is a computer, 2 is a printing device, and 3a is a first stacker. The second stacker 3b having a normal configuration is not shown. Further, 30 is an ID card, 31 is an ID storage circuit, 32
Is a collation circuit, 33 is a door lock mechanism drive circuit, 34 is a door lock mechanism, 35 is an ID reader, and 36 is an ID.
Read buffer.

The operation of the first embodiment will be described below with reference to FIGS. The operator who needs to print the secret data inputs the stacker designation and the ID data information into the computer 1 as shown in FIG. Send to 2. Upon receipt of the information designated by the stacker, the first stacker 3a is automatically electronically locked, and the first stacker 3a is automatically locked.
The printing operation is started with 3a as the output destination.

On the other hand, the ID data received by the printing device 2 is stored in the ID storage circuit 31. The addition of the ID data for designating the person who takes out the paper is not limited to the input from the keyboard on the computer side, and an ID reader may be provided to send the ID data.

After the printing is completed, the paper take-out person inserts the designated ID card 30 into the ID reader 35 of the first stacker 3a, the ID information of the ID card 30 is read by the ID reader 35, and the ID reading buffer is read. 36
Stored in.

Both outputs of the ID storage circuit 31 and the ID read buffer 36 are compared by the collation circuit 32. If these comparison results match, the door lock mechanism drive circuit 33 is driven by this match signal and the door lock mechanism 34 (electronic lock or electromagnetic lock) is released.

When the door is opened, a door release signal is output from the door lock mechanism 34, and the ID stored in the ID storage circuit 31 is output.
After the data is erased, the printed paper is taken out, and the door is closed, unless the necessary ID data is newly sent from the computer 1, the same ID card 30 has the door lock mechanism 34.
Cannot be canceled. This is because it is necessary to specify the person who takes out the paper for each work, and therefore the information in the ID storage circuit 31 needs to be erased every time the printed paper is taken out once.

Next, the second circuit configuration will be described. In the second embodiment shown in FIG. 3, an interface control circuit 37 and a display 38 are newly added to the first stacker 3a.

As shown in FIGS. 3 and 4, the print data (shown in FIG. 4A) sent from the computer 1 is
After being printed on the printing paper by the printing device 2, it is stored in the first stacker 3a designated by the stacker (shown in FIG. 4A).

The person who takes out the paper is the ID of the first stacker 3a.
When the ID card 30 is inserted into the reader 35, the ID information is added by the ID reader 35 to the interface control circuit 37 via the ID read buffer 36 and sent to the computer 1 via the printer 2. The computer 1 compares / determines whether or not this ID information is the person who took out the paper in the relevant business with the ID data that it has, and if it is the person who takes out the paper, the stacker is designated (shown in FIG. 4B). Door open signal to the first stacker 3a specified by (shown in (C) of FIG. 4)
Is sent. The first stacker 3a analyzes this door opening data by the interface control circuit 37 via the printing device 2, the door lock mechanism drive circuit 33 is driven, and the door lock mechanism 34 (electronic lock or electromagnetic lock) is released. It

If the computer 1 cannot be identified as the person who took out the paper in the job, the data is sent to the first stacker 3a designated by the rejection data (shown in FIG. 4C), and the first stacker 3a is sent.
The interface control circuit 37 of 3a analyzes it, displays a message to that effect on the display 38, and ends the operation.

Further, in the embodiment of the present invention, the stacker 3
(Alternatively, the first stacker 3a, the second stacker 3b) and the printing device 2 are described as separate devices, but the same applies if the stacker 3 is built in the printing device 2 and is the same device. Also, I
The input of the D data is not limited to reading from the card, but a ten key may be attached to the stacker and input in the form of a recitation number for each job.

[0022]

As is clear from the above description, according to the present invention, the security of the computer system on the user side and the significant reduction in operating cost can be achieved.
