Description

[Detailed Description of the Invention] The present invention organizes a large number of disc recording media into one,
The present invention also relates to a method and apparatus for processing a disc recording medium for the purpose of reading information recorded on the disc recording medium.

Traditionally, information recording media include tape, thin wire,
Sheets or shape-retentive thin plates (circular, rectangular, etc.) are known, and specific equipment is used for each medium to read the information recorded on the medium. However, tapes, thin wires, sheets, etc. are not suitable for individually storing a large amount of information consisting of a relatively short number of words, and relatively small thin plates are usually used. The organization of the recorded information during reading was mostly done manually, which resulted in the problem of poor efficiency. For example, if cards are recorded for each item sold at a store, the cards are collected and the information is collected.
Through analysis, it is possible to accurately understand distribution processes and demand trends, but if tasks such as loading large numbers of cards into readers rely on human labor, it is inefficient and the time required for analysis is large. It will become. The applicant had previously filed (Japanese Patent Application No. 173617)
56-94544)) In order to solve the above problems, a method and apparatus for processing a disk recording medium is proposed, and the medium is supplied one by one to a processing section for writing or reading information. After processing the media in , the series of operations for discharging the media to the outside can be performed continuously and at high speed. However, since the circular media was rotated during the media processing, this still hinders high-speed processing. Ta.

However, in the present invention, the medium processing is performed while the disk recording medium is held without rotating, thereby enabling faster processing.

The disc recording medium processed in the present invention is a flat disc made of a suitable material (for example, paper, plastic or other strong material), and its size is appropriately determined depending on the purpose of use. Information is recorded in advance on the surface of a disc recording medium. The recording method is perforation,
Conventionally known methods such as magnetization or barcodes are used. When the perforation method is adopted, letters, numbers, symbols, etc. are represented by combinations of holes, and the combinations of holes are made in the radial direction of the disc recording medium, and the information represented by the holes is written in circles. Do this at regular intervals along the circumference. This perforation can also be replaced by perforation in a transparent plastic disk by leaving the perforated portion and printing the rest with opaque ink.

The processing device according to the present invention is configured by integrating a device for reading information recorded on the disk recording medium and a device for supplying the disk recording medium to the reading device. The processing device will be explained based on the embodiment shown in the drawings.
Note that recording on the disk recording medium was performed using a perforation method.

Annular guide rings 11 are stacked and set on the upper peripheral edge of a rotary receiving plate 2 having a cross-sectional shape without touching each other. The distance between the lower surface of the guide ring 11 and the upper surface of the saucer 2 is set to be less than or equal to the thickness of the disc recording medium 1 so that the medium 1 cannot fit into this gap. This distance is maintained by the guide ring support 9 and a ball bearing 22 provided at its tip. The guide ring support 9 is attached to the substrate 1 on the outside of the outer cylinder 25, which will be described later.
Fixed vertically to 0. A groove-shaped guide path 12 is formed on the lower surface of the guide ring 11 to guide the movement of the disc recording medium 1 in the outer circumferential direction. A reading device insertion hole 14 is bored in the upper wall of the guide path, and a cylindrical reading device rotating portion 16 is rotatably inserted into the hole to insert the tip end into the guide path 1.
2, and its tip is brought as close as possible without contacting the upper surface of the rotating type saucer 2. The reader rotation unit 16 is provided protruding from the lower side of the reader 17, and the motor 18 for rotating the reader rotation unit 16 is installed adjacent to the reader 17.
The reading device rotating section 16 and the motor 18 are connected to the belt 4.
Connect with 6. The selector valve mounting hole 23 of the selector valve support 19 is in contact with the guide path outlet 13 of the guide path 12 formed in the guide ring 11, and the selector valve mounting hole 23 of the selector valve support 19 is inserted into the mounting hole 15 drilled in the upper surface of the guide ring 11 with an overlapping screw 36 (see FIG. 2). ) to fix the selector valve support 19. A selector valve 20 is incorporated into the selector valve support 19 so as to be rotatable up and down via a horizontal axis (FIG. 6). An electromagnet 21 is installed above the selector valve 20 to attract it and rotate it.
A medium discharge ring upper stage 5 and a medium discharge ring lower stage 6 are fixed vertically to the outer wall of the rotating type saucer 2, and an outer cylinder 25 is installed on the outside of these so as to be as close to them as possible and at a distance that they do not come into contact with each other. do. The outer cylinder 25
On one side, an upper medium discharge port 26 and a lower medium discharge port 27 are provided in upper and lower stages, and the lower edge of the upper medium discharge port 26 is connected to the upper surface of the medium discharge ring 5.
The lower edge of the medium discharge port lower stage 27 is at the same level as the upper surface of the medium discharge ring lower stage 6, or the discharge port side 2
6, 27 and fix it so that it is lower than that. In order to increase the efficiency of the reading process of this device, two or more reading devices 17 can be installed.
In this case, all the information read is processed by the computer 32. In this example, two are provided symmetrically. Therefore, two guide paths 12, a reading device insertion hole 14, a reading device 17, a motor 18, a belt 46, a selector valve 20, a selector valve support 19, an electromagnet 21, etc. are provided. Further, the necessary number of guide ring supports 9 and ball bearings 22 for supporting the guide ring 11 are provided in order to keep the guide ring 11 horizontal and maintain an appropriate distance from the rotary tray 2. As shown in FIG. 6, a medium discharge ring support upper part 38, a medium discharge ring support lower part 39, a medium discharge ring support that fixes the medium discharge ring upper stage 5 and the medium discharge ring lower stage 6 to the outer periphery of the rotating receiving tray 2. A necessary number of tool supports 40 and fasteners 41 are also provided. However, the shape and thickness of the support column 40 must be selected so that the disk recording medium 1 will not be caught on it, for example, one with a circular cross section and a thinness within the required strength limit. It goes without saying that the distance between the supports 40 needs to be larger than the diameter of the disc recording medium 1.

When the switch 29 on the control panel 28 is turned on, the saucer shaft 8 directly connected to the rotating saucer 2 is driven by the motor 49, and the rotating saucer 2 therefore rotates. At the same time, a light source 35 installed inside the rotary tray 2, directly below the reader 17 and across the upper surface of the rotary tray 2, turns on. Also a reading device 17,
Motor 18, electromagnet controller 45, control panel 2
8. The computer 32, output device 33, and photo sensor 47 are all in operation. A floppy disk is set in the output device 32. Normally, two floppy disks can be set in the output device 33 through the floppy disk insertion port 34, but in this example, only one floppy disk is shown.

First, a large number of disk recording media 1 are placed onto the rotating receiving tray 2. The disk recording medium 1 placed on the top surface moves to the periphery due to the centrifugal force caused by the rotation of the rotating tray, reaches the inner circumference of the guide ring 11, and further moves to the inner circumference of the guide ring 11 due to the friction with the top surface of the rotating tray 2. It moves in the rotational direction along the inner circumference. When the disc recording medium 1 reaches the guide path entrance 24, the disc recording medium 1 moves to the guide path entrance 2 due to the friction and centrifugal force of the rotating tray 2.
4, the guide path 12 has a width and height that allows only one disk recording medium 1 to pass through, and enters from the opening side 50 (FIG. 7) of the reading device rotating section 16, and the other end is the closed side 51. It is prevented by The reader rotation unit 16 is a cylinder having an inner diameter approximately equal to the outer diameter of the disc recording medium, and the lower end thereof has a semicircle cut out to form an open side 50 and the other semicircle forms a closed side 51.
The distance between the upper surface of the rotating tray 2 and the lower end of the open side 50 is such that only one disk recording medium 1 can pass through, and the distance between the lower end of the closed side 51 and the lower end of the closed side 51 is such that the disk recording medium 1 cannot pass through. Moreover, it does not come into contact with the upper surface of the rotatable saucer 2. The reading device rotating section 16 initially faces the guide path entrance side so that the opening side 50 can easily receive the disk recording medium 1, and if the chord of its cross section is a straight line, the chord is perpendicular to the center line of the guide path 12. If it is a curved line, the center of the circle of the reading device rotating section 16 is set at right angles to the tangential line passing through the projected point.

The reading device 17 has the reading device rotating portion 16 facing downward, inserting the lower end of the reading device rotating portion 16 into the reading device insertion hole 14 bored on the center line of the guide path 12, and aligning it with the upper surface of the rotating type saucer 2. The spacing is maintained as described above. Further, the position is such that when one disc recording medium 1 is stopped in the reading device rotating section 16, its circumference does not protrude from the guide path entrance 24.

The disc recording medium 1 is guided by the guide path 12 and is detected by the photo sensor 47 (FIG. 7) provided there just before it enters the reading device rotating section 16, and the disc recording medium 1 is read. After the time required to reach the inner wall of the closed side 51 of the device rotating section 16 has elapsed, the image received by the reading device 17 is sent to the computer 32. The light receiving section 48 of the reading device 17 electronically reads the projected image of the disc recording medium 1 using a solid-state image sensor or the like. The state in which the disc recording medium 1 enters the reading device rotating section 16 and reaches the inner wall of the closed side 51 is the reading position.
In this state, it is irradiated with parallel light rays emitted from the light source 35 directly below and transmitted through the saucer transparent portion 4 (formed along the circumference of the saucer). Disk recording medium 1
The light beam passing through the hole representing the information recorded on the disk and the light beam passing around the disk recording medium 1 are sensitive to the solid-state image sensor of the light receiving section 48 of the reading device 17, and are electronically generated by positive and negative reactions. The images on the disk recording medium 1 are connected. The image is transferred to the computer 3 at an appropriate time after the photo sensor 47 generates a detection signal.
2 and store it as an image. computer 3
The image stored in 2 is subjected to image analysis processing by a program, and as a result, it is converted into information composed of numbers, alphabets, kana characters, symbols, etc. The order of conversion starts from a predetermined position in the storage device depending on the program, so immediately after conversion, numbers, alphabets, kana characters, symbols, etc. are listed, and it is difficult to tell which one is the beginning of the information. When recording information on the disk recording medium 1, a start mark is always recorded in the first digit and an end mark is recorded in the last digit. The start mark and end mark are then detected from among these numbers, letters, and symbols. These two are always adjacent, and if the end mark is detected first and then the start mark when inspected from the left, then front reading has been performed, and vice versa, back reading has been performed. It turns out. For table reading, rearrange the information so that the start mark is at the beginning of the information. In the case of reverse reading, rearrange the arrangement so that the end mark comes first, and then change the order so that the first digit and the last digit, the second digit and the second digit from the last, and so on. Make reading order. Also, if the start mark and end mark are at both ends of a column, when the start mark comes first, it is treated as the side reading, and when the end mark comes at the beginning, it is treated as the side reading, and the order of the columns is changed. Read the table.

A check digit is previously punched in the second digit counting from the last digit of the information. This is because a check digit method is used to verify the accuracy of the read result. Therefore, when the above-mentioned rearrangement of information is completed, a check is subsequently performed within the computer 32 using the check digit system. Information whose reading results are determined to be accurate is transmitted to the output device 33 and recorded on the floppy disk inserted into the floppy disk insertion slot 34. Records whose reading results are determined to be incorrect are immediately erased. and electromagnet controller 4
Activate 5. The electromagnet controller 45 controls the electromagnet 2.
When the selector valve 1 is energized, the selector valve 20 supported by the selector valve support 19 and made of a magnetic material is attracted, and since both left and right ends of one side are supported by the pivot 44, the other side, that is, the guide path The one in contact with the outlet 13 rotates upward. The selector valve 20 is normally connected at its unfixed ends to the lower left and right ends of the selector valve support 19 by springs 43, and is pulled downward so that the top surface of the selector valve 20 and the top surface of the rotating saucer 2 are at the same level. , and the distance between them is set so that they are close to each other to the extent that they do not touch. Therefore, the disk recording medium 1 that has been correctly read is sorted into the upper stage 5 of the medium ejection ring. When the reading device 17 finishes reading and determines whether the result is correct or incorrect, the computer 32 sends a signal to the motor 18.
Rotate 1/2 turn. Then, since the open side 50 and the closed side 51 of the reader rotation unit 16 are opposite, the disk recording medium 1 held in the reader rotation unit 16 is moved to the guide path exit due to the friction and centrifugal force on the upper surface of the rotation type tray. 13 to the outside of the rotating type saucer 2.
At this time, the correct reading results are displayed on the upper surface of the upper stage 5 of the medium discharge ring, and the incorrect ones are displayed on the upper surface of the lower stage 6 of the medium discharge ring by the selector valve 20. The motor 18 remains in that state for the time required for the disc recording medium 1 to leave the reading device rotating section 16, and then rotates 1/2 turn in the same direction to return to the original state, and then starts the next disc recording. Accept medium 1, repeat the reading operation, and repeat this operation on disk recording medium 1.
Continue until no more comes. Media discharge ring upper stage 5
The lower stage 6 of the medium discharge ring and the lower stage 6 of the medium discharge ring are both fixed to the outer periphery of the rotating type receiving tray 2, so that they both rotate at high speed. Therefore, the disk recording medium 1 located on the upper surface of each disk is moving outward due to centrifugal force while making a circular motion, but is restrained by the outer cylinder 25. When they reach the positions of the upper medium discharge port 26 and the lower medium discharge port 27 provided in the outer cylinder 25, they are classified into those that have been correctly read and those that have been incorrectly read and are discharged to the outside of the apparatus. The upper medium ejection port 26 and the lower medium ejection port 27 are both sized to allow the disk recording medium 1 to pass through easily, and their lower ends are on the same level as or at the same level as the upper surfaces of the upper medium ejection ring 5 and the lower medium ejection ring 6, respectively. Provided below. When two or more reading devices 17 are provided, as many guide paths 12 as there are reading devices 17 are provided. When the disk recording medium 1 enters a certain guide path, depending on the reading device in the guide path 12, the disk recording medium 1 enters a certain guide path.
One or two or three of them enter the reading device rotating section 16 and the guide path 12, and no more can enter. Therefore, the subsequent disc recording medium 1 further continues its circular motion along the inner circumference of the guide ring 11 and enters the next guide path 12, and when this guide path 12 is filled with the disc recording medium 1, The subsequent disc recording medium 1 continues its circular movement as before and enters the guide path 12 which can be entered. On the other hand, the reading devices 17 perform reading processing independently, release the disc recording medium 1 to the outside, and accept the next disc recording medium. Therefore, one of the disk recording media 1 which is waiting for entry, that is, continues to move in a circular motion, is allowed to enter the guide path 12. Both readers perform this operation independently. The disk recording medium 1 waiting to be read on the rotary receiving tray 2 continues its circular motion and waits until it reaches the empty guide path 12, and eventually all the disk recording media are processed.

Disk recording media 1 that are determined to be incorrect and ejected are reinserted into the device and read, but those that are finally ejected as errors are read by an appropriate method and the information recorded on the control panel 28 is read. Additional input is made using the keyboard 30 provided in the computer, and additional information is recorded on the floppy disk inserted in the output device 33. Also, depending on this keyboard 30,
Information that is common to the entire information or a specific group of information, such as the date, area code, and store code, can be output to the floppy disk separately from being read from the disk recording medium 1.

The floppy disk on which the information has been recorded is taken out from the output device 33, treated as an input to another computer for data processing, and subjected to desired processing using an arbitrary program. FIG. 8 shows another embodiment of the apparatus according to the present invention, in which reading of the disc recording medium 1 is carried out outside the rotating receiving tray 2. That is, the holder 52 for the disc recording medium 1 is rotatably installed in close proximity to the guide path outlet 13 of the guide path 12 formed on the guide ring 11 installed above the rotating receiving tray 2 .
The holder 52 is constructed by overlapping a spiral-shaped stopper 54 on a transparent disc 53, and has four accommodating portions 55 formed therein, and a central shaft 56 connected to a panel motor (not shown). ), and is configured to rotate intermittently about the angle at which the housing portion 55 is formed. A light source 35 is disposed on the lower side with one housing section 55 in between, and a reading device 17 similar to the above embodiment is disposed on the upper side.
Place.

In the above embodiment, the disk recording medium 1 that has passed through the guide path 12 is stored in the empty storage section 55.
Each time a piece faces the guide path outlet 13, one piece is transferred to the holder 52 side. When the disk recording medium 1 that has been moved to the holder 52 side is positioned below the reading device 17, it is read and then ejected to the outside. The area around the holder 52 is the guide path exit 1.
A covering plate (not shown) is provided to prevent the disk recording medium 1 from flying out when the holder 52 rotates, leaving the portion facing the disk holder 3 and the ejecting portion.

The effects of the present invention will be explained.

By loading a large amount of disk recording media 1 at once,
The fact that reading is carried out one by one means that information is read by aligning the front and back of the recording medium, top and bottom, regardless of the method used in the past, such as perforating the recording medium, magnetizing it, OCR method, barcode method, etc. must be loaded into the device. When using this device, there is not only no process of arranging and loading the recording media, but also no skill is required to handle the device, and the conventional method requires loading the recording media by placing them in a magazine. Therefore, it is not possible to continuously supply the medium, but this device can process the desired amount without stopping operation.

The movement of the disk recording medium in the device relies on centrifugal force caused by the rotation of the rotating tray and friction between the surface of the rotating tray and the disk recording medium, so the structure is simple and robust, and it is easy to manufacture and maintain. is easy.

The method of stopping a disc recording medium in a reading device for reading and ejecting it for ejection after reading is performed by rotating the reading device rotating section by 180 degrees. After being released, it is rotated 180 degrees to accept the next medium.
This also has an extremely simple structure and can operate at high speed.

Since the method of feeding the disc recording medium 1 to the reading device 17 is circular movement of the disc recording medium 1, the disc recording medium 1 can continue to wait until an opportunity for reading comes, and the operation of the reading device 17 is independent. Therefore, it is possible to provide two or more reading devices. The limit on how many can be provided depends on the ability of the computer 32 to process the reading results and organize them as output. There are 2 readers
If more than 1,000 pixels are provided, the reading capacity will be doubled or tripled, and the processing capacity of the entire apparatus can be dramatically improved. Conventionally, this type of media reading device had a slow processing speed of about 200 to 400 sheets per minute, so it took too much time to process a large amount of information, and as the times progressed, the performance of computers in general increased dramatically. Nowadays, this problem has been solved, which has become a bottleneck in the entire data processing process. Since one reading device of this apparatus can process 600 sheets per minute, in this example, two reading devices are used and it is possible to process 1200 sheets per minute.

The energy for discharging each result of the determination of whether the reading is correct or incorrect uses the rotation of the rotary tray and the resulting centrifugal force, so the structure is rational and simple. Further, even if reading devices are provided at two or more locations, the disk recording media are collected as correct and incorrect as a result of reading, and are classified into correct and incorrect and discharged from the device, so a sorting step is not necessary.

The reading device performs reading by exposing the light-receiving portion of the disk recording medium to the light that has passed through the perforations, so the reading speed is extremely high and a large amount of processing is possible. Moreover, the structure is extremely simple and manufacturing is easy.

When the output is recorded on a floppy disk, the floppy disk can immediately be used as an input medium for other data processing computers. This is extremely efficient as it eliminates intermediate steps.

Secondary Effects The present invention enables early understanding of transactions between retailers and customers in the process of product distribution in the market, that is, manufacturing, wholesale, retail, and customers, and uses computers to perform statistics and accounting. A typical method is one that is applied to the processing of

Cosmetics, medicine, books, records, electronic products,
When shipping clothing and other items to retail stores,
A disk recording medium that records product codes, etc. is pasted on each corresponding product, and when the product is sold to a customer at a retail store, it is removed and stored, and the disc is stored in the required units such as daily, weekly, or monthly. and send it to the designated location. This device is installed at the location where the mail is received, and by operating the keyboard on the control panel, data common to a group of specific information, such as the retail store code and date or period, is stored in advance in the computer. When all disk recording media are input into the device, each piece of information is recorded on the floppy disk inserted into the output device along with the retail store code and date or period. Taking a chain store as an example, it is possible to collect disc recording media from all participating retail stores, so after performing the above processing, the recorded floppy discs are processed separately using a computer. If we were to collect statistics such as sales results, we would be able to grasp the sales status of products very quickly and accurately, which would be important data for sales, but it is important to note that in the past, the sales status at the retail store level was not reflected on the manufacturers. It usually takes 3 to 4 months
In many cases, products that do not sell well are manufactured based on production plans due to delays of several months or more, and there is a high possibility that these products will remain unsold, and there are restrictions on the recall of unsold products under the Pharmaceutical Affairs Law. The reality is that products are discarded to prevent price declines, to secure warehouse space, or to become obsolete. In the economic situation of our country where saving resources is extremely important, the present invention is effective as a powerful means to make it possible.

Also, from a corporate perspective, it contributes to sound management by producing products that sell and not producing products that do not sell.Furthermore, if accounting processing is performed using the information collected by this device, it will have a speedy and labor-saving effect. I can give you.

Conventionally, two methods have been used to collect sales information at the retail stage and comprehensively perform statistical or accounting processing.

One is to transmit partially collected information using a terminal such as a POS (POINTS OF SALES) to a central computer using an online real-time method or an online batch method, where the necessary processing is performed. This method is expensive and complicated, and requires a large number of highly knowledgeable and skilled personnel and a long period of time to construct.
In particular, it costs a lot of money to install a terminal in a large number of retail stores to use it, and it also requires skill to operate the terminal. It is simply impossible to disseminate it to retail stores.

Another method is to tag products and record information such as product codes on them, collect them at the retail stage, and place them in a processing center where the information can be read and processed. As mentioned above, with this device, the recording media are arranged manually, so the process is labor-intensive, and the processing speed of the reading device is slow, so it takes too much time to process a large number of tags and prepare the data to be input into the computer. It takes a lot of time to get there. On the other hand, as the performance of computers continues to improve, this bottleneck is becoming a drag on improving the performance of the entire processing process.

The present invention is an economical and efficient means of solving the above problems.
