DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desk top (desktop type) and a portable bar code printer, and more particularly to a printer for printing a bar code indicating a number.

[0002]

2. Description of the Related Art The rapid processing of mail is of great concern not only to companies but also to the majority of individuals. Over the last few years, the number of mails delivered year by year has been increasing and delivery has been delayed, despite higher postage rates. In the United States, domestic mail was treated in the same way as international mail. In other words, if "shipping" is specified, it takes a long time to deliver,
If designated "airmail", the turnaround time was significantly reduced. For example, sending mail by sea from the east coast of the United States to the west coast (and vice versa) usually takes nearly a week, but can be sent by air (with an extra 2-3 cents). For example, it was delivered in two days, sometimes one day.

Not long ago, the designation of "airmail" for domestic mail was abolished. From then on, domestic mail delivery has taken longer, sometimes at times as long as the old "ship". The delay seems to have occurred mainly at the stage of sorting and classifying an ever-increasing number of mail items by final destination (name destination). Long ago, the United States Postal Service introduced a postal code system that adds a postal code (so-called zip code) after the state name in an address. This indicates the final delivery location of the postal matter by municipalities / regions using a 5-digit postal code. In addition, the United States Postal Service has recently introduced a so-called zip (zip code) + 4 code system. This is, in effect, a number indicating the route to the door of the mailing address.

[0004] In order to more effectively use the Zip + 4 code (zip code + 4 digit number) system, the United States Postal Service uses a special bar code system called a post net to zip each letter. An automatic sorting machine that reads codes was introduced. This device is installed at the post office of the postal corporation, and reads the presence of a zip + 4 code / postnet / barcode on the envelope of the sent letter. Is processed as a barcode mail as it is. On the other hand, for postal items without a barcode, OCR
(Optical Character Reading) Using a device, determine whether the zip or zip + 4 code is written on the envelope as part of the address. If so, the automatic sorting machine prints a postnet barcode indicating the Zip + 4 code in the "postnet clear zone" at the lower right corner of the envelope, and prints a letter on the postnet bar. Sort based on code. When the zip or zip + 4 code cannot be read by the OCR device (for example, when an address is handwritten), it is necessary to review the zip or zip + 4 code with human eyes and manually enter an appropriate zip + 4 code. In this case, the processing of the postal matter is naturally delayed.

If a zip + 4 code / postnet barcode is printed in the postnet clear zone of the envelope when the mail is posted, the mail can be processed quickly, Benefit to those involved. Many companies pre-print their zip + 4 code postnet barcode on return envelopes (eg, used to pay bills, etc.) just for that reason. This results in a dramatic increase in the speed of mail delivery and a reduction in postal handling fees. In fact, by using zip + 4 code post net barcode for mail, delivery time required is 1 to
Can be reduced by two days. Furthermore, the handling fee of the postal company is considerably saved, so that a user who sends a large amount of mail can set a discounted postage.

[0006] Many companies and individuals can minimize the use of expensive next morning delivery flights by adopting a method in which the recipient's zip + 4 code / postnet / barcode is stamped on mail. (Reducing the burden on the recipient), leading to a lower rate of postage price increase or avoiding a price increase.

[0007]

However, at present, low cost devices that allow the average company and individual to print Zip + 4 code postnet barcodes on mail at low cost are available. Not developed. Even the cheapest “desktop” printers for postnet barcodes currently on the market
In the US $ 10,000 range. This is not an affordable price for most potential users as well as beneficiaries.

According to the present invention, when a user writes an address on an envelope prior to mailing, the zip code of each addressee, a zip code (postal code + a 4-digit number), a postnet bar code, and the like are converted to mail. It is an object to provide a low-cost device for printing.

Further, according to the present invention, when a user writes an address on an envelope prior to mailing, a zip +
4. An object of the present invention is to provide a portable envelope printer (printing machine) for printing a code, a postnet barcode on a mail.

Further, according to the present invention, when a user writes an address on an envelope prior to mailing, a zip + 4 of each addressee can be used.
It is an object of the present invention to provide a manually controlled desk-top envelope printer for printing code, postnet and barcode on mail.

Still another object of the present invention is to allow a user to print a zip + 4 code / postnet / barcode of each addressee on mail at the stage of addressing an envelope prior to mailing. To provide an inexpensive electronic or electronically controlled desk top envelope printer.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Portable and desk-top barcode printers are techniques well known to those skilled in the art.
All other barcodes, such as those used to mark products sold at retail outlets and scanned by sales equipment, are used on a one-to-one basis. That is, when the product code is composed of nine digits, the used barcode is a nine-digit barcode composed of barcodes indicating each of the nine numerals. In contrast, Zip +
The 4 code (zip code + 4 digit number), unlike other barcodes, has a tenth digit that acts as a parity bit for computer binary data. A cashier scans a box of cornflakes at a supermarket. In this case, if there is an error in the bar code, the scanning device does not recognize the code and refuses to read the code, or displays an incorrect item name and price. In the latter case, the customer or cashier will notice this. In the case of postnet barcodes, on the other hand, misreading the barcode will result in the targeted letter being delivered to a completely different location.
For this reason, in the printer of the present invention, the 10
The second digit is used to check the other nine digits. The use of the tenth digit is a feature of the postnet barcode of the present invention and the printer therefor, which sets the present invention apart from conventional barcode printers. In other words, the present invention is not readily conceived of from barcode printers known to those skilled in the art, which, to date, has led to the development of inexpensive portable or desk-top post-net barcode printers. The reasons were not.

FIGS. 1-9 show a bar code printer 10 embodying the present invention in its simplest form (ie, portable). As shown in FIG. 9 in a greatly simplified form, the printer 10 comprises an upper jaw or jaw 12 and a lower jaw or jaw 14 hingedly connected at 16 in the figure. Upper and lower jaws 1
2 and 14 are, for example, jaws 1 when gripping handle 18.
2 and 14 can be connected to a pair of handles 18 so that they stick together as shown by arrow 20, sandwich the envelope placed between the two jaws 12 and 14, and print on the envelope. This pinching and printing operation by a pair of hinge-like jaws is well known to those skilled in the art and is not in itself a novel part of the present invention. To simplify the description and avoid redundancy, details regarding this part are omitted.

Most of the printer 10, and its components, are desirably formed of the tough, friable plastic commonly used today in such equipment.
That is, the parts of the present invention may be mass-produced at low cost using injection molding techniques, and then the parts may be combined by snap fitting and / or bonding using an adhesive. Good. The upper jaw 12 includes most of the operation unit of the printer 10 therein, and supports the operation unit. Upper jaw 12 is hollow and includes a bottom surface 22, side walls 24, and a top surface 26. Ten number selection wheels 28 are rotatably mounted on a shaft 30 whose both ends are supported by a pair of support members 32 formed on the bottom surface 22. further,
Ten barcode printing wheels 34 are rotatably mounted on a shaft 36 supported at both ends by a pair of support members 38 formed on the bottom surface 22. As shown most clearly in FIG.
The zero number selection wheels 28 are installed so as to be parallel to the ten barcode printing wheels 34 and to be in the same row. In addition, as best shown in FIG. 4, ten digit selection wheels 28 extend over the top surface 26 through rectangular slots 40 provided in the top surface 26, and also have ten number selection wheels 28. Ten number selection wheels 28 are mounted on the ten barcode printing wheels 34 so that the barcode printing wheels 34 extend below the bottom surface 22 through rectangular slots 42 provided in the bottom surface 22. ing. Number selection wheel 28
Each of the ten digit selection wheels 28, via a plurality of string belts 44, which fit into traction grooves 46 formed in the bar code printing wheel 34 and the ten bar code printing wheels 34, respectively. It is connected to the corresponding one of the wheels 34. Each string belt 44 is preferably a loop formed of a twisted, non-stretchable material such as nylon. By adopting such a configuration, the post net printing performed by the bar code printing wheel 34 is performed.
In order not to create unnecessary gaps between bar code symbols, ten bar code printing wheels 34 are
They can be installed close enough to each other. further,
Other methods may be used to position the bar code symbol printing element based on the numeric input. For example, using the corresponding post-net barcode symbol, which is mounted on the underside, prints a number on one side of 10 adjacent plastic strips and slides the strip to show the number and its It is also possible to select a corresponding barcode symbol and determine a position for printing. However, the method using wheels as described above is preferable for various reasons.

Each of the digit selection wheels 28 is located at an equal distance on its outer circumference, radially located,
With indicia 48 of numbers from 1 to 9. Similarly, the barcode printing wheels 34 each have a post net corresponding to a number from 0 to 9 in the form of an embossed bar 50 radially located at an equal distance on its circumference.
It has a bar code symbol. The number selection wheel 28 is interconnected at a 180 degree position relative to the barcode printing wheel 34. That is, when the slot 40 on the top surface 26 indicates a predetermined number, a postnet barcode symbol corresponding to the predetermined number is positioned to be printed via the slot 42 on the bottom surface 22. I have.

The ink required to print the postnet barcode on the envelope can be configured to be supplied in one of two ways. As shown in FIG. 3, a removable cartridge 52 may be used. The cartridge 52 includes a main body 54 on which an arm (arm) 56 is installed, and the arm 56 extends outward from the main body 54. The type used in recent typewriters is coated with a pressure-moving ink 60,
A Mylar strip (or similar strip) 58 runs along a arm 56 from a supply reel (not shown) inside body 54 and returns to a take-up reel (not shown) inside body 54. If necessary, turn the knob 62 connected to the take-up reel to
8 can proceed. When using the cartridge 52, the arm 56 is held in the jaw 12,
Also, the slot 58 contacts the barcode printing wheel 34 when the jaws 12 and 14 are squeezed simultaneously.
The arm 56 is inserted into the slot provided in the face 64 of the upper jaw 12 so that it is in the proper position below the two. As the jaws 12 and 14 are grasped, the ink 60 under the slot 42 is dispensed and a corresponding postnet barcode is printed on the envelope.

Instead of the cartridge 52, a specially configured stamp pad 66 may be used to inked the barcode print wheel 34 directly. The stamp pad 66 includes a pad 68 sized to cover the entire slot 42 and impregnated with a liquid ink 70. Pad 68
Is attached to the end of the positioning arm 72. When using the stamp pad 66, the pad 68
Is positioned so that it is over slot 42, and jaw 1
Simultaneously squeeze 2 and 14 and transfer ink 70 onto barcode print wheel 34. Thereafter, the stamp pad 66 is removed, the envelope is inserted, and the jaws 12, 14 are simultaneously grasped again. This transfers the ink 70 from the barcode printing wheel 34 onto the envelope.

One of the roots of the present invention is an envelope alignment gauge 74, shown in FIG. The gauge 74 has a bottom stop (bottom stop) 76 and a light end stop (right end stop) 78. When the envelope 80 is inserted into the gauge 74, a predetermined portion within the postnet clear zone of the envelope 80, where the postnet barcode is printed, which meets the criteria set by the United States Postal Service. The stops 76 and 78 are positioned with respect to the slot 42 so that the slot 42 is located above the position of the slot 42.

Next, the tenth numeral of the bar code will be described. This is a special purpose computer 82 embedded (or adhesively mounted) inside the top surface 26.
Is calculated by FIG. 12 shows the configuration of the computer 82 of this embodiment, and FIG. 1 shows the logic used in the computer 82.
3 is shown in the flowchart. As the logic used in this embodiment, digital logic on a single chip as conventionally used can be used. Each component is mounted on a normal printed circuit board, as is conventionally done. Power is supplied from room lights by solar cells 84 connected to logic 86. The single digit liquid crystal display section 88 is connected so as to be driven by the logic 86. Also, a key 92 corresponding to a number from 0 to 9 and a “clear” key 94
Is connected to the logic 86 as input means. An operation example of this computer is shown in FIG.
A description will be given according to the logic flowchart of FIG. The user is the first nine numbers (ie, Zip + 4 code)
Is input to the ninth digit of the ten-digit number selection wheel 28. The user presses the “clear” key 94 and inputs the first nine digits into the key 92. When the logic 86 detects that the ninth number has been input, it calculates the tenth number and displays this number on the display unit 88. The user sets the displayed tenth number on the number selection wheel 2
Manually fill in the rest of 8 and print the entire postnet barcode. The tenth number is calculated according to techniques well known to those skilled in the art. The calculation can be easily ascertained using a number of publications available from the United States Postal Service, such as "Business Mail Preparation Guide."

In the above embodiment, the portable printer 10
However, by mounting the jaws 12 and 14 on the base and performing a gripping operation with a lever instead of the handle 18, it is possible to easily reconfigure the printer into a manually operated desktop (desktop) printer. it can.

A printer 10 'according to a second embodiment of the present invention will be described with reference to FIGS. 10 and 11 and a logic flowchart of FIG. Printer 1
0 ′ is a desktop (desktop) type and is driven electronically or electrically. As in the first embodiment, the printer 10 'includes an upper jaw 12 including an operating component, and
It has a lower jaw 14 having an alignment gauge 74. The alignment gauge 74 is for receiving the envelope, placing and holding the envelope between the jaws 12,14. Like the computer 82 of the first embodiment,
The printer 10 'of the second embodiment includes a logic 86'. Logic 86 'is driven by a suitable power source 96 of sufficient capacity and is connected to the logic 86' to drive a printing press 98 that actually prints the postnet barcode on the envelope. The power source 96 is preferably a low voltage transformer (transformer) currently used in many electronic devices that can be plugged directly into a wall socket. Furthermore, in order to make it simple and portable, a battery and / or a rechargeable battery can be used as necessary. The keypad 90 ′ of this embodiment includes a numeric key 92 and a “clear” key 9.
4 and a “print” key 100. Printing press 9
8 is an ink jet printing machine (for example, Hewlett.
It is desirable to use an ink jet type device manufactured and sold by Packard). The alignment gauge 74 is desirably configured to move the envelope horizontally to the front of the printing press 98. Alternatively, a dot matrix print head may be used as the printer 98. In this case, an independent ink supply is required (which is why an ink jet printer is more desirable). As the mark supply means, the cartridge 52 shown in FIG. 3 can be used.

The operation of the printer 10 'of the second embodiment will be described with reference to the logic flowchart of FIG.
The user can access the jaw 1 in the alignment gauge 74.
Insert the envelope between 2 and 14, press the "Clear" key 94, and enter the number of the zip + 4 code into the number keys 92. The entered numbers are displayed on an LCD (liquid crystal display) display section 88 '. After entering up to nine digits, the user can press the "print" key 100. If a nine-digit number has not been entered when the "print" key 100 is pressed, an "error" message is displayed. If the printing is not performed, the number to be inserted into the tenth digit string of the ten-digit number sequence is calculated as in the first embodiment. Thereafter, the printing machine 98 prints a 10-digit postnet barcode on the envelope. When printing the same zip + 4 code many times, it is only necessary to insert a new envelope and then press the “print” key 100 again.

Anyone with knowledge of postnet barcodes, or as known to those skilled in the art,
A barcode is a bar with the same width and a number of bars arranged at equal intervals.
Some are short. In any of the embodiments of the present invention, when printing a postnet barcode, the first and last part of the barcode sequence prints a long bar. In an automated embodiment of the present invention (second embodiment), the first and last long bars are printed by logic 86 'and printing press 98. Further, in the manual example (first embodiment), as shown in FIG. 2, a fixed long bar printing machine arranged adjacent to the end of the barcode printing wheel 34 (102 in the figure). Is printed.

The present invention may be embodied in various other forms without departing from its spirit or essential characteristics. For example, in the description of the present invention, the most common “envelope” is used as an example. However, using the printer of the present invention, a post net barcode corresponding to the destination zip + 4 code is printed on a label or the like. Printing is of course also possible. Therefore, the word "envelope" used in the claims is for the purpose of clarifying the description, and does not limit the printing object to the envelope, and naturally includes other printing objects. Have been.

[0031]

As described in detail above, the printer of the present invention can be manufactured at a low cost, and a bar code corresponding to a predetermined digit is pre-printed on a postal matter before posting, so that the mail can be promptly delivered. It greatly contributes to.
