Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an output device, and for example, to an output device that determines permission to output data contents and outputs the data.

[Prior Art] This type of device usually has a function of dumping the contents of various data stored in the hard disk to the contents of data input from the outside to an output unit such as a display unit. For example, the dump function of the contents stored in RAM etc.
), and when the CPU receives a predetermined dump command from an input section such as a keyboard, it starts a predetermined dump to the output section.

In particular, when data is input from an external storage device such as a magnetic tape, the data is stored in the input buffer at -1.
The data is expanded onto a predetermined memory via the input buffer. The data developed in this manner is dumped as necessary, and thereby the contents recorded on the external storage medium such as magnetic tape can be known.

[Problems to be Solved by the Invention] However, regardless of the content recorded on the external storage medium, an unspecified user can output the content of the data to a display unit, etc., so, for example, confidentiality is required. There is a problem in that even if the content is important, it is easy to know the content.

The present invention has been made in view of the problems of the prior art described above, and its purpose is to prevent unspecified persons from knowing the contents of data recorded on an external storage medium. The point is that it provides an output device.

[Means for Solving the Problems] In order to solve the above-mentioned problems and achieve the purpose, the output device according to the present invention includes an input means for inputting data from the outside, and stores output permission information for the data. storage means,
collation means that reads a password when outputting the data and collates the password with the output permission information;
The apparatus is characterized by comprising an output means for giving permission to output the data when the results of the collation means match.

[Operation] According to the above configuration, the input means inputs data from the outside, and the storage means stores data output permission information. When outputting data, the collation means reads the password and collates it with the output permission information, and when the collation results match, the output means grants permission to output the data.

[Embodiments] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic configuration diagram showing the configuration of the output device of this embodiment.

In the figure, 1 is the main body of the output device of this embodiment, and 2 is a CPU that controls the entire main body 1. 3 is a control program;
This ROM stores a program for error processing, a program for performing processing according to a flowchart shown in FIG. 2, which will be described later, and the like.

A RAM 4 includes a work area for executing various programs stored in the ROM 3, a temporary save area for error flags and the like during error processing, and an area for expanding input data from an external device. 4a is also included in the RAM 4 and is a password designation storage buffer that stores a password for determining output permission added to input data.

Reference numeral 5 denotes an input data interface (hereinafter referred to as I/F) unit that connects to an external device to input and output data, and in this embodiment, is connected to the magnetic tape processing device 20. Reference numeral 6 denotes an input data buffer that stores the input data input from the input data I/F section 5 for each predetermined data length and outputs it to the CPU 2. 7 is a keyboard section equipped with various keys for control, etc.; 8 is a VIDEO RAM (hereinafter referred to as VR
AM). 9 is a CHARACTERGENER that expands the data expanded in VRAM 8 into a pattern
The ATOR section (hereinafter referred to as CG section) 10 is a CRT display section that displays the contents patterned by the C0 section 9.

11 is an output data buffer that stores various data such as input data to be output to the printer 21 for each predetermined data length, and 12 is an output data 1/F unit that inputs and outputs various data to and from the printer 21. .

In the output device 1 of this embodiment configured as described above, the operation in data input/output is performed by the CPU 2 as shown in FIG. 2(a).
This is done based on the flowchart shown in (b).

First, predetermined data is input from the magnetic tape processing device 20 (step St). Data is stored in the RAM 4 via the input data buffer 6 for each predetermined data length.

Next, the input data is analyzed to detect whether a password has been specified or not (step S2). If a password is specified, the contents of the password specification and the file name of the predetermined data for which the password is specified are registered in the password specification storage buffer 4a (Step S4), and a message instructing the password input is sent to the CR1142111 section 10.
(Step S5). This password input instruction also includes a selection field for selecting whether or not to output the input card and password.

Next, when a password is inputted from the keyboard section 7, the content of the input data is requested to be output in step S.
6) Compare the input password with the password included in the input data input in step S1 (step S7). When the respective passwords match in this way, a message is displayed on the CR1142111 section 10 to instruct the selection of the output light that will output the contents of the input data next (step S9). Then, the output light corresponding to the input data is selected (step 5IO).

If input data is to be output to the CR1142111 section 10, a predetermined amount of data is transferred to the C
Patterned by 0 part 9, CR1142111 part 1
0 (step 511). When the content of the input data is printed by the printer 21, the data is output to the printer 21 for each predetermined data length via the output data buffer 11 (step 512).

When all data output processing is completed (step 513), it is selected whether or not to input further data from the magnetic tape device 20 (step 514). If data input processing is to be executed, step S1 is performed again.
If no input processing is to be performed, all processing is terminated.

As described above, according to this embodiment, it is possible to prevent the contents of data input from the outside from being known to an unspecified person, and therefore it is possible to provide an output device that can maintain confidentiality regardless of the contents of the data. .

Furthermore, although an offline system using a magnetic tape processing device was used in this embodiment, the present invention is not limited to this, and data may be transmitted from an external device such as a host computer as long as it does not depart from the spirit of the present invention. It can also be used in online systems such as uke-to-tori.

Alternatively, the effective range of one password designation may be set for each volume of magnetic tape, or for each group of data, for example.

Furthermore, before the input data is expanded into the RAM 4, it is determined whether or not a password has been specified at the time the input data is stored in the input data buffer 6. If a password is specified, a password input instruction is displayed on the CRT display 10 and the system waits for the password to be input. If the input password matches the password of the input data, the input data is expanded in the RAM 4. If they do not match, the password input instruction is issued again or the process returns to normal processing. In this way, permission or prohibition of input may be determined based on whether the input data matches the password.

Further, in this embodiment, a display method in which input data is displayed through the C0 section 9 has been described, but the present invention is not limited to this, and the code data at the time of input may be output to be displayed as is.

[Effects of the Invention] As explained above, according to the present invention, it is possible to prevent the contents of externally input data from being known to an unspecified person, so that the output can maintain confidentiality regardless of the contents of the data. equipment can be provided.
