Technical field

 The present invention mainly relates to a latent image printing apparatus for recording latent image information on a side edge portion of a 135 type mouth film. Height

 The latent image information such as the screen number (frame number) and the product type is imprinted on both sides including the performance part of the 135 type mouth film by the latent image printing device. It is necessary to check whether such latent image information is imprinted on the correct position.

 Therefore, in the prior art, as shown in Patent Document 1, for example, a virtual performance signal output at the same timing as the pitch of the performance is dedicated to the clock / rotary encoder signal. The circuit is molded and the actual film perforation 3 is inspected to see if the positional relationship between the film and the burn-in drum has shifted by comparing it with the signal that was detected.

 A number of patents relating to a latent image printing apparatus have been filed, such as Patent Documents 2 to 5, and the like. Is barely mentioned.

However, a virtual performance signal output at the same timing as the pitch of the performance shown in Patent Document 1 is used as a computer to rotate. It is not preferable to use a dedicated circuit to form the circuit based on the signal of the damper because the circuit has a complicated structure and the cost increases.

 Also, information is burned in the part of the film side edge that avoids the hole in the perforation line, but if the hole is burned in, it will be a defective product. Must be eliminated. However, this is not always done enough.

 Also, unexpected problems may occur during the design phase. In order to cope with this, when an inspection item is added, there is a problem that adding a dedicated circuit individually increases the design man-hours, increases the number of IC components, and increases costs.

 The present invention solves such a problem of the prior art, and even if there is a burning defect, it can be eliminated by low-cost detection means, and the latent image of characteristic data which is burned to the side edge of the film. It is an object of the present invention to provide a latent image printing apparatus capable of stably and accurately obtaining a latent image. (Patent Document 1)

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the description in this column does not limit the technical scope of the claims or the meaning of terms. The assertive description in the following embodiments of the present invention indicates the best mode, and does not limit the meaning of the terms of the present invention or the technical scope.

FIG. 1 is a schematic explanatory view of a latent image printing apparatus 1 of the present invention. Fig. 2 is a partial side view. The interior machine 10, which is an assembling machine that cuts the film into fixed lengths and winds it up on a spool, enters the cartridge. The side edges F1, F2 on both sides of the film F are characteristic of the interior machine 10. Exposure means 100 for printing a latent image as data is provided, and the exposure means 100 is composed of two optical systems 101, 102, and the optical systems 101, 100, respectively. Each of 2 is based on the output information from the dedicated control board (1, 2, 3, 4) 131, 1332, 1333, 1334 of the controller 130, and is used as a large number of light emitting sources. Light-emitting diodes 15 1 and 15 2 composed of LEDs are selected to emit light, and each of the emitted light sources is toothed through a reduction projection lens 15 3 and 15 4 respectively. An image is formed on both side edges F 1 and F 2 of the film F which is conveyed and moved by the wheel or sprocket 16 1 and the guide rollers 16 6 and 16 7. A perforation detector 165 is provided in the middle of the transport path, and an encoder 162 is connected to the sprocket 161 through a force ring. The rotation amount is fed back to the dedicated control boards P1, P2, P3, P4.

4 signs

 The control device 130 also includes a signal board 10 for transmitting signals to the interior device 10 and a bar code reader 1 for detecting the bar code of the patrone sent to the interior device 10. 23, a keyboard 121, a display device (CRT) 122, and a CPU board 120 connected to a new computer 124 for editing characteristic data.

 The latent image printing apparatus 1 of the present invention is a printer that prints images on both side edges of a photographic film, and is a production apparatus that can be continuously operated for 24 hours.

 The number of printing lines was 4 lines in total, two lines each in parallel with the side edges F1 and F2. Each line was arranged in red and green in the right angle direction (the width direction of the film) and shifted by half a dot each. An image is formed with a total of 16 rows of LEDs, with 4 rows of 3-dot LEDs. FIG. 3 is a block diagram showing an embodiment of a latent image setting process in the latent image burning device 1 of the present invention.

 FIG. 4 is a block diagram showing an embodiment of an inspection process during the formation of a latent image in the latent image printing apparatus 1 of the present invention.

 As shown in FIG. 3, a data file is provided in advance for decomposing characters and figures as characteristic data into dot patterns and storing them. Furthermore,

 There is template data in the light emission pattern.Latent image setting operation means is provided to select the type, size, brand, etc. by the setting operation of the operator and determine the image to be printed.

The required image is read from the file by the latent image setting operation means, and an image for one film is organized and developed on the light emitting data memory. When the preparation is completed, the position of the film is detected by the rotary encoder 16 2, the data is read out sequentially from the light emission data memory, a plurality of light emitting diodes (projecting light sources) are selected and light is emitted, and one line of image is formed on the film. When the exposure for one film is completed, control returns to the top of the emission data memory by the origin signal and repeats the same image pattern.

 As shown in Fig. 4, three channels are available for the luminescence data memory: one currently in use (channel 1), one for switching the next type (channel 3), and one for switching the date (channel 2). Have been.

 In addition, it is possible to change to channel 2 instead of channel 3 and, in the case of date switching, overwrite it for type switching and then switch the date, and then change the type to the vacant channel and set the date again.

 As a result, different light emission patterns can be set for the current use pattern and the next use pattern, respectively, and when the above conditions are satisfied, that is, when a command to switch to the next use light pattern is received. , Can be switched instantly o

 In the case of switching, normal products must be continuously produced without causing false detections in both abnormal and normal cases.

 Writing to the currently used channel is prohibited. Data can be written to the other empty channels for the next light emission without interrupting the light emission processing.

 This device has an abnormality detection function such as failure or setting failure, and can notify the production equipment generator of the occurrence of the abnormality and automatically discharge the defective product.

An outline of these functions will be described in more detail with reference to FIGS. 3 and 4 described above. Then it looks like this: It should be noted that data can be transferred between the blocks shown in FIGS. 3 and 4.

 1) The latent image setting function uses existing files and data tables newly created with Excel, etc., selects the type and size of film, decides the images and their arrangement, and also sets the emission time, etc. Determine parameters. Selection methods include individual selection of product type, size, brand, etc., and batch selection by product code. Latent image settings can be operated at any time, regardless of equipment shutdown.

 2) The data expansion function expands the burn-in image data on the emission data memory based on the selected latent image information, and sets various parameters in the parameter register. The light-emitting data memory is 23 bits, but it also has a 9-bit data area for inspection including parity, so necessary data is also written. Emission data memory and parameter registers are available in three channels: one for emitting light, one for switching types, and one for switching dates. It is designed so that the channel that emits light cannot be hard-accessed, and rewriting during emission is prohibited to prevent erroneous operation. Data input for the next emission can be written to other channels without interrupting the emission process.

3) As shown in the flowchart of Fig. 5, the initial setting function ensures that these settings, including the usage status of the channel, are completely reproduced when the power is turned on. The setting information is stored in a non-volatile memory backed up by a battery or the like, and can be backed up for a long time even if the power is turned off. If the set latent image cannot be reproduced due to some trouble, clear all the emission data memory, parameter registers, and stored information for that channel, set them to `` not set '', and set the latent image settings for all channels described above. Perform erasure. 4) In Fig. 4, the position measurement function performs the normal / reverse rotation discrimination processing of the rotary encoder 162 that detects the film movement signal. Unless the pulse returns, the double exposure to the same location is prevented by not outputting a pulse. Also, double the precision to increase the film position detection accuracy.

 5) The light emission function reads out data sequentially from the light emission data memory based on the pulse of the one-way encoder and selectively emits the light emission diode as the film moves forward. The emission time is set independently for red and green for each type of film to adjust the density and color tone of the image.

6) The alignment function aligns the image and the film in the direction of travel. The position of the film is measured with a rotary encoder based on the cycle signal input for each film, and the start address of the flash memory and the start position of the film are matched. Adjust for each LED column, superimpose images of four LED columns in each row, and determine the layout of the entire row.

7) The product type switching function sets the parameters such as the image pattern and the light emission time in advance by key operation, and uses the product type switching button or an external product type switching signal for each LED row. Switching is performed sequentially at the beginning of the next film. The processing of each row is switched instantaneously at the break of the film without interruption, so no abnormality occurs due to the switching.

8) One of the latent image information is date information indicating a production date. The same principle as type switching, but the date information is automatically set by the computer board every day at N, but can also be switched by the date switching button or an external date switching signal. Dates were replaced with alphabets and combined with unit numbers Encoding is preferred.

 9) The external signal output function is to output, for example, a signal of “emitting light”, “occurrence of abnormality”, “size” to a production equipment sequencer.

 10) The production control bar code setting function is used for the production control bar code reader shown in the schematic diagram of Fig. 1 so that the latent image to be burned is not mistaken when the power is turned on and when switching. The bar code data is set. After setting, the barcode of the patrone being produced is read from the barcode reader and collated. As described above, in addition to the method of changing the setting value of the bar code reader, the latent image burning device reads the bar code of the patrol line detected by the internal device and sets the same in the production control bar code reader. It is also possible to adopt a method in which the whole number is collated with the latent image bar code.

 1 1) The display functions shown in Fig. 1 and Fig. 3 enable the setting status display of each channel, the dot image display of the latent image, the latent image setting operation screen, and the display of the contents of the error, respectively. It is.

 1) The abnormality detection function detects an abnormality such as a failure or a setting error, stores the details of the abnormality in the memory, reads out and displays the occurrence of the abnormality from the memory as shown in the flowchart of Fig. 6, and displays The defective product can be automatically discharged by notifying the sequencer.

 13) The file update function allows the file to be automatically transferred from another laptop computer by key operation when updating the file. Alternatively, L AN may be used instead.

The actual image and the number of print lines are as shown in the array diagram in FIG. That is, the side edges Fl and F2 on both sides are four rows of a side mark section, a piece number section, an upper performance section, and a lower performance section, each having two rows. Minutes are also printed on one line, excluding holes. When viewed from the emulsion side, the image image has a reverse character relationship.

 Next, the configuration of the light source LED will be described with reference to the schematic diagram of FIG. Rows A and B shift the rows of dots by half a dot in the array direction and overlap the images so as to fill the gaps between the dots in a staggered manner. The rows A and B in red and the rows A and B in green There are 4 columns, 2 colors of images can be overlapped and the colors can be mixed, each LED column is composed of 23 dots, and each LED column has 4 columns per row on each side, 4 rows 16 rows, total number of LEDs is 3

It becomes 68 pieces. The superposition of the images in each row in the film transport direction is performed by electrically adjusting the top light emission start position of each LED column based on the cycle signal for each row. (Adjustment is unnecessary because the film width direction is determined mechanically.)

 The principle of abnormality detection performed by the present invention in such a latent image printing apparatus will be described.

 The structure of the inspection data is as shown in the schematic diagram of Fig. 9, which includes a parity bit on the 23-bit emission data for characters and figures, LED row synchronization, switching error, emission inhibition, It has 9 bits of inspection data consisting of 1 bit for each phase, 1 bit for inspection at the end of the film, and 3 spare bits.

 One address (dot) is 0.04 as the data length of the film.

With a maximum capacity of 8 1920 addresses = 389 1.2 mm, counting at 75 mm, the amount of film length data currently in progress is `` Film length mmZO.

0475 m + 58 addresses ". 58 is a margin that does not cause defects such as perforation holes even if the fixed length of the film varies depending on the cutting position. (1) First, the principle of detecting a synchronization error will be described. The following measures are taken to confirm that the synchronization of each LED string is correct.

 (1) Using the LED column synchronization signal of the detection data, confirm that the signals in each column are output simultaneously during one cycle, that is, that they are synchronized.

(2) As described above, the accuracy of the processed data is set to 1 address = 1 dot = 0.0475 mm per address in terms of film length, as described above, thus improving the detection accuracy.

 ③ Set the data by shifting each column based on the difference (parameter B) of the set value of position adjustment of each column.

は In the data arrangement, areas are used for each channel and for each size, and channel mismatch and different sizes are detected.

 場合 If the crossover between the circuits is broken or floating, it is detected as abnormal.

⑥ If the output signal is always on or always off, it is detected as abnormal.And the schematic diagram in Fig. 10 shows that at a certain moment, for example, LED row 1 is at point A, and £ 0 row 16 is at point B at the same time. This indicates that by outputting data simultaneously, it is possible to burn data to the same position in each column.

At this time, if the light emitting position of each column is correct, the LED column synchronization signals of all the columns become L at the same time, and this case is regarded as normal.

 (2) Channel abnormalities are detected as follows.

 Check that the emitting channel of each LED row matches. Therefore, the following measures are being taken.

① At the time of switching, as shown in the switching diagram in As shown in the schematic diagram of Fig. 11, at a moment, LED row 1 is scanning point A, and LED row 16 is scanning point B at the same time. It can be seen that point A has already been switched to point A 'and point B is just before switching. In the switching area shown in Fig. 9 and Fig. 12 of the inspection data, the channel shows a temporarily different range. The switching area signal turns on and off almost simultaneously for each column.

 (2) For this reason, in the range other than the switching area, always check that all LED rows are the same channel and match the channel instruction.

(3) Abnormal light emission on the perforation a is detected as follows. As shown in the diagram of Fig. 14, the length of the hole of the performance, that is, slightly larger than the length of the hole of the performance for safety, is actually 58 addresses. Check that no light is emitted in the area. Therefore, the following measures are taken.

 (1) Write (H) as emission inhibition data using the emission inhibition signal of the inspection data, and if even one LED emits light in that section, it is abnormal.

 ② Lines without holes can emit light in all areas.

 For example, in the schematic diagram of FIG. 13, since there is an image image at a position where light emission is prohibited, it is inevitable that light emission in this way will result in a failure.

 () File errors are detected as follows.

 Detects slippage between the film and the drum, and at the same time detects poor perforation (no holes) in the film. Therefore, the following measures are being taken.

① As shown in the schematic diagram of the performance phase detection signal in Fig. 15 and the related diagram in Fig. 16, the performance phase detection signal of the inspection data And the timing of the actual perforation detection signal is compared.

(2) Set parameter C arbitrarily from 0 to 100 address, and adjust the phase to the signal of the performance detector 165.

 (3) Parameter D is an arbitrary value between 0 and 100, preferably between 0 and 20. The upper limit of the phase shift is set.

 な の で Since the perforation detector 1 65 has two circuits on the rainy side, detection can be set for two circuits.

 為 In order to eliminate the influence of the sensitivity of the performance detector 165, it is preferable to detect the deviation of the hole center position when the performance detection signal does not come.

 (5) Scanyanella is detected as follows. This is for confirming that the last data of the image data area of one film corresponding to the size of the luminescence data memory has been luminescence scanned until the end of each cycle. Therefore, the following measures are being taken.

(1) As shown in the schematic diagram of Fig. 17, at the moment when the address is returned to the beginning by the origin signal, it is confirmed that the film end signal of the inspection data is being output.

 ② Parameter E indicates the width of the termination signal and can be set arbitrarily from 0 to 100 addresses. Here, it is set to 58 addresses. In this way, it is confirmed that the cycle of one film is completely scanned every time.

 The actual width of the end signal varies due to the variation in the stop position when cutting the film, and the actual standard length varies. If the origin signal is input somewhere within 58 addresses, it is normal.

(6) Light emission abnormality is detected as follows. As shown in the diagram in Figure 18, LED light emission is individually detected and compared with the light emission data. Therefore, the following measures are being taken. In the drawing, the light emission time is set by changing the film sensitivity and the like.

 ① After a certain time (0.1 s or less) from the emission signal ON, the emission is instantaneously confirmed.

 (2) This makes it possible to identify the LED whose light emission / light off does not match the light emission data, and notifies this to the computer board.

 (7) The abnormal lighting is detected as follows. As shown in the diagram of FIG. 19, confirm that the LED is turned off in units of columns. Therefore, the following measures are being taken. ① After a certain period of time (preferably 2 βs or less) from turning off the light (light emission signal OF F), until the next light emission, even if the light emission is detected for an instant, it is considered abnormal.

 ② Whether the disconnection, short circuit, or any other cause, the lighting of the light emitting diode must be reliably detected.

 ③ Independently of this, if the time during which the light is not turned off exceeds 100 ^ s using the one-shot timer, it is considered abnormal.

 (8) Parity error is detected as follows. Check if the flash is fired based on the correct flash data.

 Therefore, as shown in the schematic diagram of FIG. 20, the parity check of the number of light emission is performed at the timing of light emission abnormality detection by one parity bit corresponding to 23 light emission detection bits. In other words, when Η is used as the parity, if the total number of パ リ テ ィ of the parity 1 bit and the number of luminescence (対 応) corresponding to the 23 bits for luminescence data is even for each column, it is normal or odd. Judge as abnormal.

(9) The total parity error is detected as follows and stored in the light emitting data memory. Confirm that the data expansion is correct.

 Therefore, as shown in the schematic diagram of FIG. 21, the total number of parities (H) is sequentially counted from the beginning with the scanning of the emission data memory, and the count signal and the preset total number of parities are used as the origin signal. The timing is checked and checked, and if they match, it is determined to be normal.

 (10) Cycle signal Double input is detected as follows. Check that the cycle signal enters only once per cycle o

 For this reason, as shown in the diagram of FIG. 22, the input of the cycle signal is held, and if there is a re-input before resetting by the origin signal, it is determined to be abnormal. Industrial potential

 By using an LED assembly and a control board on which the recording data for emitting light is written as a light source, the latent image data based on the emission data and most of the inspection data are integrated. With the latent image printing device of the present invention, errors in printing and setting can be easily detected and promptly dealt with, and defective products are not shipped together with the product, and the latent image printing device is compact. It can be manufactured at low cost. In addition, the present invention has made possible a compact and reliable check of some inspection items in which the latent image data based on the emission data and the inspection data are not incorporated in the body. In addition, a plurality of spare bits are provided in the multiple inspection data that are integrated, so that even if there are some inspection items that you want to add in the future, you can easily It is possible to provide a latent image burning device that can be used at low cost and that can be used with confidence.
