Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information file device for storing and accumulating image information such as documents and drawings, and more particularly to an information file device for connecting a printing device to output image information.

[0002]

2. Description of the Related Art In recent years, an information file device having a large storage capacity has been attracting attention as the amount of information has increased and office work has been rationalized.

In such an apparatus, the image information to be stored is usually read by reading a document such as a document or a drawing with a reading device such as an image scanner, performing an editing process as necessary, and then searching the recording medium such as an optical disk. It is stored and registered along with the appropriate keywords that are sometimes assumed. Then, the image information is searched by inputting and designating this keyword, and the desired image information is retrieved and displayed on a display device such as a CRT.
It is also possible to output to a printing device such as a printer, record on paper, and visually check.

When outputting to a printer, the printer is connected to an information file device. These printers have different print specifications, such as limited printable sizes (printer A can print only up to B4 size, but printer B can print up to A3 size). It is common that there are so-called different models, such as having a control command for an instruction.

Therefore, conventionally, when connecting an information file device and a printer, an interface circuit having a control program suitable for the model of the connected printer is prepared, or a switch for switching the model of the connected printer. Alternatively, the model of the printer was set in advance by using the jumper.

[0006]

However, in the conventional connection as described above, it takes a considerable amount of labor and time to prepare an interface circuit dedicated to each type of printer to be used, and a switch and a jumper are required. It requires specialized technology and some time to set the printer model in advance due to factors such as the above, and in the end, there is concern that the user will make a setting error and the printer will inevitably have printing problems. To be done.

The present invention has been made in view of the above circumstances, and provides an information filing device that solves the above-mentioned problems by determining the printer model to be connected by the printer interface circuit. Is.

[0008]

The present invention comprises a storage means for storing a plurality of image information, a search means for searching image information to which the keyword is added from a keyword, and a display means for displaying the image information. A printer interface circuit for discriminating the model of the printing device from the model information and controlling print timing according to the connected printer in an information file device connected to the printing device having model information; And a control unit for performing print control according to the model of the printing apparatus determined by the circuit.

[0009]

In the information filing apparatus of the present invention, the printer interface circuit determines the printer model based on the printer model information, so that printing control that meets the specifications of the connected printer can be performed.

1 and 2 show an embodiment of the present invention. FIG. 1 is a block diagram showing an embodiment of the present invention, and FIG. 2 is a flowchart of processing relating to a printer interface circuit. It is a figure.

In FIG. 1, at (1), image information is input by optically scanning a document with a reading device such as an image scanner. (2) is an image memory for temporarily storing image information, and (3) is a keyboard for inputting data such as keywords, instructions for image information editing processing and operation commands for registration, search, printing and the like. (4) is C for displaying the read image information or for setting the registration of the image information
A display device such as RT, (5) an optical disk device for storing a plurality of image information together with keywords for the search,
A printer interface circuit (6) discriminates the model of the connected printer (7) and, at the same time, performs print timing control according to the connected printer. The printer (7) is an 8-bit command for each model.
It has model information such as "H", "01H", or "02H", and is connected to the printer interface circuit (6) by an interface cable (8). Reference numeral (9) is a CPU (central processing unit), which controls recording and reading of image information to and from the optical disk device (5), control of the entire information file device such as display control of the display device (4), and model information of the connected printer. Then, the print program corresponding to the printer is controlled.

First, registration and search of image information in the information file device will be described. The image information is read by the reading device (1) in the form of image information and is temporarily stored in the image memory (2). The image information stored in the image memory (2) is displayed on the display device (4) and, if necessary, the keyboard (3) is operated to perform the editing process. Next, when a keyword to be added to the image information to be registered, such as a title name and a registration date, is input from the keyboard (3), the CPU (9) stores the image information in the optical disc device (5) together with the keyword and registers it. Done. On the other hand, the search for image information is done using the keyboard (3)
Is operated to instruct the CPU (9) to perform a search process. Then, when a keyword is input from the keyboard (3), C
The PU (9) retrieves image information corresponding to the input keyword from the optical disc device (5) and displays desired image information on the display device (4) or outputs it to the printer (7).

Next, the print control of the printer connected to the information file device will be described with reference to the flowchart of FIG.

Now, when the printer (7) is connected to the printer interface circuit (6), the printer interface circuit (6) sends a connection detection signal to the CPU (9), and the CPU (9) causes the printer (7) to operate. Detects the connection. Then, the keyboard (3) is operated to instruct the CPU (9) to perform the printing process (S1). Then CPU
(9) sends an operation status command to the printer interface circuit (6). The printer interface circuit (6) detects the power detection signal output from the printer (7) and confirms the operable state (power ON state) of the printer (7) (S2). If the printer (7) is in the inoperable state (power-off state), a cancel command is sent to the CPU (9), which causes the CPU (9) to operate.
In (9), the printing process is canceled (S3). Printer (7)
Is enabled, a model information command indicating the model of the printer (7) is requested to the printer (7) (S
4). Upon receiving the model information command, the printer (7) sends model information (for example, "00H") to the printer interface circuit (6) as an 8-bit command, and the printer interface circuit (6) detects the model information and is connected. The printer model is determined (S5). At the same time, print timing control is performed according to the connected printer. Also, the model information is sent to the CPU (9) (S6), C
The PU (9) receives the model information and executes control of the print program corresponding to the connected printer (7) (S
7).

The model information may be a signal such as "1" or "2" in addition to the 8-bit command described above.

[0016]

As described above, according to the present invention, since the printer model is discriminated by the printer interface circuit provided in the image processing apparatus, there is no troublesome printer model setting, and there is a model setting error. Printing troubles such as printing failure can be prevented.
