(Example) The present invention will be explained below based on the illustrated example. Second
Figures (a) and (b) show an aperture card applied to the information reading device according to the present invention, and this aperture card 11
This is a bar code that converts the band hole information from a conventional aperture card and records it outside the image frame when shooting film. FIG. 5A shows a card that also has bunch holes and can be used with conventional reading devices.

Figure 3 shows aperture card 1 as an L information recording medium.
The details of film section 1 are shown, and the largest image on film F is AO size 1/30 and AI size 1/2.
1.2, A2 size, 28 x 39.5 mgm taken at a reduction ratio of 1/15, etc. Further, the window portion of the aperture card 11 is 36×48 mm, and the window portion of the film holding adhesive tape is 31×43+wm. Barcode string B, which is a shooting history information string, is recorded in the margin (indicated by ■) in the direction of the length of the section.

Next, FIG. 4 shows a barcode recording device, in which numeral 1 denotes a photographing camera, and the photographing camera 1 includes an optical element using a liquid crystal shutter array for exposing a barcode to a film 7 at high density. f-2 is built in, and the barcode row B is exposed on the film based on shooting data and historical image data, for example, by a command from an external controller such as a computer that manages the image processing as a film. and record it. Here, the exposure position is the above-mentioned 0 copy so as not to overlap with the image information even at various reduction ratios. Here, the photographing history information string of image information refers to, for example, the document size, reduction ratio, document creator number 2 date, IQ document management number, etc.

FIG. 1 shows an embodiment of an information reading device according to the present invention,
This is a schematic configuration diagram of an aperture card reading optical system. In the figure, 11 is the aperture card mentioned above, and a film F is pasted to the corner window of the aperture card 11. The film F is connected to a lamp 12 and a condenser lens 13. An image sensor 1 such as a one-dimensional photoelectric conversion element array having a linear array of light receiving elements, such as a COD (charge-coupled device), is illuminated and the projected image is formed by an imaging lens 14.
The image is formed on the scanning plane of 5. Here, when the aperture card 11 is loaded into the guide 16, the aperture card 1
A photointerrupter 17 detects whether the front and back sides of 1 are in the correct direction. That is, as shown in FIG. 1, when the aperture card 11 is loaded in the normal direction, the photo interrupter 17 is blocked from light by the corner of the aperture card 11; The corner cut portion 11a determines that the photointerrupter 17 is not shielded from light and is on the back side. On the other hand, the image sensor 15 is fixed to a carriage 18, and a light shielding plate 19 attached to one end of the carriage 18 is attached to the scanning unit/
The photointerrupter 21 provided on the substrate 20 is stopped at a position that shields the photointerrupter 21 from light, and is waiting for the aperture card 11 to be loaded. This position is the home position of the image sensor 15. Then, at the position where the aperture card 11 has completed loading, the barcode row B on the film F is imaged substantially parallel to the image sensor 15 waiting at the home position. That is, since each component was arranged so that when the image sensor 15 stopped at the home position and the film F was set at the reading position, the barcode row B was projected onto the image sensor 15 in unison, the 4ii shadow Scanning for reading history information can be made unnecessary.

Next, the reading operation of this embodiment will be explained based on FIGS. 5 and 6. In FIG. 5, 30 is a control unit, and after the aperture card 11 has been loaded, the control unit 30 reads barcode row B with the image sensor 15, inputs this output information, and obtains shooting history information of film images. . Based on this history information, the paper size of the printer 32 is selected, and the scanning reading range of the image sensor 15, the speed of the sub-scanning motor 22, and the interpolation rate of the output information of the image sensor 15 are selected.

Determine the thinning rate. In addition, the reading scanning control section 3
4 is a sub-scan motor 22 .4 based on the numerical value determined by the control section 30 . The image sensor 15 and an image sensor control circuit (not shown) are driven to read and scan the film image. At this time, the carriage 18 is moved by the sub-scanning motor 2.
2 through the wire 23 in the direction of the arrow in FIG. 1, and after scanning to a predetermined position, the sub-scanning motor
By reversing , it stops at the home position again.

The image information read by the image sensor 15 is visualized on a transfer paper by a printer 32 such as a well-known laser beam printer, inkjet printer, or thermal printer.

That is, the reading operation of this embodiment will be explained according to the flowchart shown in FIG. When a reading command is issued, the presence or absence of a barcode is determined in step (■), and if barcode B is recorded, the code information is recognized in step (2), and then the paper size of the printer is selected in step (2). After determining the scanning speed of the image sensor 15, the interpolation rate 9, and the thinning rate of the output information of the image sensor 15, scanning reading is performed in step (2), and a copy image is output from the printer 32 in step (2). If the barcode is not recorded in step ■ above,
In step ■, the message "There is no barcode, please determine the paper magnification" is displayed, and in step ■, manually enter the copying conditions such as paper size and magnification, and then move to step .

Furthermore, in the above embodiment, an example was shown in which the barcode B2 character information recorded on the film F is information on the shooting history itself, but in addition to this, shooting history information may be connected to a reading device as shown in FIG. The information on the film F may be used as the search code.

In the above embodiments, the barcode recording method, the format, format, and position of the information to be recorded, the configuration of the reading device, scanning methods such as film scanning and image sensor scanning, scanning direction, arrangement of optical projection means, etc. Various design changes can be made to the output device for the read image information (a thin optical disk of a printer may be used).

(Effects of the Invention) The information reading device according to the present invention has the above-mentioned configuration and operation.For example, selection of paper size, automation of lens magnification, omission of history information reading means, and mis-pasting of history information and image information. This eliminates the need for checking, significantly shortening the time for image copying, and reducing costs. In addition, since the standby position of the one-dimensional photoelectric conversion element array is placed at a position where it is projected in accordance with the photographing history information array, mechanical scanning for reading the history information is not required.
This has the effect that the processing capacity per unit of time for automatic image reading can be significantly improved.
