4. Display of image C (image output: data-specific information)
5. Waiting for next input (presentation operation output: operation specific information)
6. Playback of audio D (audio output: data specific information)
7. End of program (presentation operation output: operation-specific information)
[0023]
FIG. 5 shows the bar code B and the data linked to the bar code B and the presentation operation in association with each other. As shown in FIG. It is preferable to add image data to be linked and a presentation operation because it is possible to determine what information the bar code B holds.
[0024]
The above is the flow of the program execution. Next, a specific example of a barcode reading method will be described.
A. As shown in FIG. 6, a total of 10 frames 51 for specifying the position where the barcode B is to be attached are provided on the mount 50 where the barcode B is to be attached, as shown in FIG. Printing is performed, and the reading order is set to “from the upper left, then from the upper right”. Numbers 1 to 10 on the left side of the frame 51 are frame numbers. (Frame number), which is the reading order of the barcode B. The bar code B corresponding to the data used for the presentation and the presentation operation is pasted on the mount 50 in order. The bar code B attached at the end is operation-specific information that prompts the end of the program. A guide 11a composed of an L-shaped projection is provided at the upper right of the material placing table 11 of the material presenting device 10, and the upper right corner of the mount 50 is abutted against the inside of the guide 11a to determine the reading position. .
[0025]
As shown in FIG. 7, the camera 13 displays the bar code of one mount 50 on the frame No. The barcodes are sequentially read from step 1 (step S701), and it is determined whether or not the barcode has been read a predetermined number of times (step S702).
[0026]
B. Frame Fixing Method As shown in FIG. 8, a frame position mark 52 indicating the position of the frame 51 is added to the left side of the frame 51 printed on the mount 50. The frame position mark 52 is preferably inconspicuous when added by printing an invisible infrared light absorbing paint. Then, a barcode B is attached to the inside of the frame 51, and the mount 50 is placed on the material placing table 11.
[0027]
As shown in FIG. 9, when reading the bar code when the frame position mark 52 is added with the infrared light absorbing paint, first, the optical filter 15 is inserted into the imaging optical path of the camera 13, and the infrared light 16 is used. Then, the mount 50 on which the barcode is pasted in the frame 51 is irradiated, and the camera 13 captures an image of the mount 50 to capture an image (step S901). The captured image is an image composed of only infrared light by inserting the optical filter 15, that is, the frame position mark 52. Next, from the position of the frame position mark 52 to the position of the frame 51 on which the barcode is pasted (left side of the frame position mark 52), the frame No. The numbers are stored in order from 1 (step S902). Next, the optical filter 15 is removed, the irradiation of the infrared light 16 is stopped, and the camera 13 sets the bar code on one mount 50 to the frame No. The reading is performed sequentially from 1 (step S903), and it is determined whether or not the predetermined number of readings has been completed (step S904). When the predetermined number of times has been completed, the reading is completed.
[0028]
In the above-described frame fixing method, the barcode reading operation can be performed more accurately by adding the following form regarding the format of the mount 50.
(A) Recognizing the Number of Barcodes Attached to the Mount As shown in FIG. 10, how many barcodes are attached to the mount 50 at the left end of the header (upper margin column) of the mount 50? And a header mark H indicating the position of the bar code B 'is printed on the left side of the bar code B' by printing an infrared light absorbing paint. Have been. According to the mount 50, the barcode B 'is read by using the header mark H as a clue, and the number of barcodes to which the mount 50 is attached is recognized (the mount 50 in FIG. 10 is for 10 sheets). At the time of reading the barcode B, ten barcodes B are read per one mount 50.
[0029]
In FIG. 10, seven barcodes B are pasted on the ten frames 51. However, if there is no predetermined barcode in the frame 51, it is determined that no barcode is pasted, and the reading is terminated. You may. Also, as shown in FIG. A mark box M for selecting the frames 1 to 10 is added, and a header mark H 'for recognizing the positions of these mark boxes M is added. It is also possible to invalidate by marking the mark box M with black, and to read the barcode B of the unmarked frame as valid. In this case, contrary to the above, the bar code B of the frame 51 marked with black can be made valid.
[0030]
(B) Recognizing the size of the backing sheet As shown in FIG. 12, a header mark H1 is added to the left end of the header of the backing sheet 50, and a footer mark H2 is added to the right end of the footer (lower margin column) of the backing sheet 50. These marks H1 and H2 are added by printing an infrared light absorbing paint. In this case, at the time of reading the barcode B, first, the header mark H1 of a predetermined shape is searched from the upper left of the mount 50, and when the header mark H1 is detected, the frame position marks 52 are sequentially read, and the lower right footer mark H2 is read. Is recognized, the position of the frame 51 corresponding to the frame position mark 52 with respect to the mount 50 is stored. In this case, the start point of the reading position is recognized by the header mark H1 and the end point is recognized by the footer mark H2 according to the size of the mount 50. Therefore, the number of bar codes B, that is, the frame 51 can be set arbitrarily.
[0031]
(C) Sticking position free method As shown in FIG. 13, a barcode position mark 53 is added to the left end of the sticker to which the barcode B is added. The bar code position mark 53 can be added by printing an infrared light absorbing paint like the frame position mark 52 described above. Then, the stickers of the barcodes B are affixed to the mount 50 in the order from upper left to lower and upper right to lower of the mount 50. The position where the barcode B is attached may be rough as long as the order is correct as shown in FIG. 13. The mount 50 on which the barcode B is attached in this manner is placed on the material placing table 11 of the material presentation device 10. The reading of the bar code B is the same as that of the above-mentioned frame fixing method shown in FIG. In this method, since the barcode position mark 53 is added to the sticker of the barcode B, the position of the barcode B can be detected even if the position where the barcode B is attached to the mount 50 is rough. There is also an advantage that it is not necessary to use a dedicated mount on which the frame 51 is printed.
[0032]
FIG. 14 shows an example of a process when there are a plurality of mounts. In this case, the start switch 19 is pressed after placing the first backing sheet on the material placing table 11 (step S1401), and one bar code is read by the camera 13 (step S1402). Then, it is determined whether or not the barcode is linked to the end of the program (step S1403), and if No, it is determined whether or not one sheet of paper has been completed (step S1404). When one mount has been completed, the second mount is placed on the material mounting table 11, and the process returns to step S1401. If No in S1404, the process returns to step S1402 to continue reading the barcode. If it is determined in step S1403 that the barcode is linked to the end of the program, the reading of the barcode ends.
[0033]
According to the system of the above embodiment, continuous and automatic output of data can be performed without using conventional dedicated automatic display software, and a presentation operation is automatically instructed to output a data. Is automatically controlled. In this way, the presentation operation can be delegated to the present system, so that the burden on the presenter is reduced, and in some cases, the presentation can be performed without the presenter.
