(Problems to be Solved by the Invention) However, in such a conventional example, when setting a predetermined repeat search mode, it is necessary to press the key 101 many times as described above, and the operability is extremely poor. It had

Furthermore, even when displaying the input contents on the display section 102 when setting the mode, there are cases where the number of inputs is too large to display all the input contents, and therefore the input contents cannot be confirmed on the display section 102, resulting in incorrect input. The problem was that there was an extremely high risk of this happening.

Therefore, it may be possible to reduce the number of key operations when setting a mode by storing a predetermined search mode in advance, but if a large number of search modes are prepared, which search mode will be used for the input 'J fil. It is inconvenient to take pictures, as it is difficult to know which input number corresponds to the input, and a comparison table is required for this purpose, and the operability is still poor.

Therefore, the present invention has been made to solve the above-mentioned problems of the prior art, and its purpose is to make the arrangement of the display section of the input means correspond to the image frame arrangement of the information recording medium, so that input operations can be performed. By matching the arrangement of parts to the type of search mark.

To provide an information retrieval device 2 which enables easy input of a large number of search modes while checking a display section, and improves operability by reducing the number of operations of an input operation section when setting a search mode. It is in.

(Means for Solving the Problems) In order to achieve the purpose of item E, the information retrieval device according to the present invention detects a search mark attached to an information recording medium and searches for a desired image frame. Information Search VT Co., Ltd. provides input means for inputting a search mode for repeatedly searching the image frames, and the input means includes a display section arranged in correspondence with the image frame arrangement of the information recording medium, and a display section for each of these. Each display section has an input operation section corresponding to the type of the search mark, and is configured to display the search order of image frames on the display section based on the search mode input from the input operation section. .

(Function) In the present invention having the above configuration, the search mode input means includes display sections arranged corresponding to the image frame arrangement of the information recording medium, and the type of the search mark for each of these display sections. By being equipped with an input operation section compatible with 1 display section and input operation section, it is possible to set the search mode while assuming the arrangement of image frames from the arrangement of the display section and input operation section, making it possible to perform input operations extremely easily. . In addition, by configuring the display section to display the search order of image frames based on the search mode entered on the input operation section, it is possible to enter the search mode P while checking the display contents of the 1 display section. .

The structure is such that when multiple elements detect a mark at the same time, it can be determined that the mark is a large mark.

When the frame number A of a desired image frame is input into the input device of the above-mentioned search device, the motor M1 is driven and the IL solenoid SQL1 is activated. This causes the capstan roller 2 to release the microfilm F from the cartridge L.
The microfilm F is pulled out from the cartridge 1 by contact with the microfilm F, and the leading end of the microfilm F is fed toward the take-up reel 8. When the leading edge of the microfilm F approaches the take-up reel 8, the winding remoter M3 is driven, and when the leading edge of the microfilm F winds around the take-up reel 8, the motor Ml and solenoid SQL 1 become inactive, but the microfilm F
is continuously fed by the rotation of the take-up reel 8.

The number B of marks detected by the mark detector 17 during feeding of the microfilm P is compared with the numerical value A of the frame number input in advance, and if they match, a stop F signal is generated, the brake solenoid 5OL3 is activated, and the take-up shaft is stopped. Braking 11, same 5OL2
The motor brakes the shaft of the motor M2 to stop the rotation of the feed spool due to inertia, the feeding of the film is stopped, and the image of the frame with the desired number A is projected onto the screen via the projection lens.
