Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a microfiche retrieval device capable of searching a plurality of microfiche sheets using, for example, one keyboard and projecting and displaying information.

Conventionally, the retrieval device shown in FIG. 1 has been commonly used as a means for retrieving microfiche and projecting information on a screen.

That is, when the operator 1 operates the keyboard 2 and enters the necessary conditions for the microfiche to be searched,
It is input to the computer 4 via the cable 3.

Then, the computer 4 sends a search command signal for the fish number and piece number to the search device 6 via the cable 5 based on the keyed-in information.

Therefore, the search device 6 performs a search, sets the corresponding microfiche on the screen 6a, and projects and displays the microfiche.

However, when it is desired to continuously project a plurality of pieces onto the screen using the above-mentioned device, it is necessary to move the positions of the pieces onto the screen, which results in idle time for the operator.

Furthermore, there are also inconveniences such as the inability to project two types of pieces onto the screen at the same time when it is desired to compare them.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to eliminate the operator's playing time based on the movement time of the microfiche in the retrieval device, thereby making it possible to continuously project a large number of pieces. The aim is to provide equipment.

An embodiment of the present invention will be described below based on FIG. 2.

In the figure, 1 is an operator, and a keyboard 2 is provided near the operator 1.

The output of this keyboard 2 is transmitted via a cable 3 to an arithmetic processing unit having a control circuit, such as a computer 10.
It is connected to the.

That is, the computer 10 calculates the projection order of the microfiche (not shown) to be projected onto a retrieval device (to be described later) and the microfilm on which the data is photographed, that is, the pieces (not shown), and then predicts the pieces to be projected.
Controls necessary for operation such as projection time are performed.

Further, a cable 11 is connected to the first output terminal of the computer 10.
A second output terminal is connected to the first search device 12 via a cable 13, and a second search device 14 is connected to the second output terminal via a cable 13.

Incidentally, the carousels (not shown) of the first search device 12 and the second search device 14 each store a large number of identical microfiche (not shown), and 12 a and 14 a are the carousels (not shown) of the first search device 12 and the second search device 14 . This is a screen provided in front of the device 12 and the second search device 14.

Next, the operation of the present invention based on the above structure will be explained.

First, the operator 1 keys in the conditions set on a desired microfiche into the computer 10 using the keyboard 2.

Then, the computer 10 sends a search command signal necessary for searching for microfiche to the first search device 12 and the second search device 14 based on the keyed-in conditions.

That is, the first retrieval device 12 and the second retrieval device 14 are alternately instructed as to the fish number, piece number, and projection order of the microfiche to be projected onto the screens 12a and 14H.

Based on this instruction, for example, the first search device 12
When the microfiche piece to be stored in the Roussel is projected onto the screen 12a, the second microfiche piece to be projected is the second retrieval device 14.
The search has already been completed from the carousel of
It is arranged to wait for projection onto a.

Therefore, the screen 12 of the first search device 12
When the first piece finishes projecting on a, the second search device 1
The second piece can be immediately projected onto the screen 14a of No.4.

In this way, the screen 1 of the 1 search device 12 is sequentially
2a and the screen 14a of the second search device 14, it becomes possible for the operator 1 to eliminate the waiting time for the projection, that is, the play time.

Further, according to the operator's request, it is also possible to have the first search device 12 or the second search device 14 stop any piece, and have the other search device sequentially project the pieces to be compared.

As explained above, the present invention is equipped with a set of search devices including a plurality of search devices, and sends a microfiche search command signal to these search devices and instructs the projection order of the microfiche to cause the microfiche to be projected. It is characterized by

Therefore, the retrieved microfiche can be used for practical purposes such as sequentially projecting pieces on a screen, or stopping any piece on one screen and sequentially projecting pieces to be compared on the other screen. This is effective.
