     BACKGROUND OF THE INVENTION 
     The present invention relates to an automatic mail-processing device with full functions, and more particularly to an automatic mail-processing device which can be operated by only one postal clerk to perform all delivery types and additional service types of all kinds of mails, and the functions of which include automatical weighing, postage calculation, charging, postage stamping, receipt printing, register receipt printing and regular daily, weekly, monthly income listing whereby the postal business can be practiced systematically, automatically, accurately and highly efficiently. 
     The mail-receiving and mail deliverying operations in current Post Office are quite complicated. They can be sorted according to their characters as follows: 
     (1) mail character: leer, printed matter, small packet, commercial document, small packet, electronic mail, etc. 
     (2) delivery area: domestic, international (further divided into various districts or countries). 
     (3) delivery type: air, sea/land, land/air, regular. 
     (4) service type: common, register, special, insure, declare, delivery, advice, attest, express, prompt delivery, etc. 
     (5) receiver/deliver amount: individual or bulk. 
     (6) charging manner: according to weight or number, also considering mail character, delivery area, delivery manner, service type, and receive/deliver amount to charge generally. 
     The above-mentioned various procedures are managed through respective counters wherein the weighing is practiced according to different standards, and the postage is calculated according to complex charge list, and therefore the equipments needed in these procedures are quite complicated and not so easily maintained. Moreover, the numberous procedures waste enormous labor and are apt to cause an uneven work distribution and low working efficiency and thereby errors occur frequently. Particularly the mailer always wastes a lot of time when waiting. 
     Furthermore, the postage stamps used in general post offices are transmitted to the postal counter after the following sequential complex procedures: design, printing, storing, delivery and receiving. These procedures are performed at quite high expense. Moreover, when mailing a mail, the mailer must go through weighing, postage calculation, buying the stamp, attaching the stamp to the mail, and then dropping the mail into the mail box, etc. The dispatched mail must thereafter be checked for overweight, postage due, and then stamped, sorted, etc. Considerable large work loading results therefrom. However, the aforesaid procedures have been adopted long since. Although the post administrations of various countries have tried to improve the defective operation, but nothing innovative is developed. 
     It is therefrom tried by the applicant to develop the present automatic mail-processing device to eliminate the aforesaid shortcomings existing in conventional mail-processing system.

The facsimile 150A is well known in the art, and therefore a detailed description thereof is omitted. 
     Please now refer to FIGS. 2A and 2B. The operation of one embodiment of the present invention is illustrated by a flow chart. The operation procedures of the present invention are generally divided into four types wherein the first thereof is the processing of weight-counting standard mail; the second is the processing of weight-counting non standard mail; the third is the processing of sheet-counting charged mail; the fourth is the processing of electronic mail. With respect to the weight-counting standard mail, the processing thereof starts from F1 and goes to panel clearance F2 and stand by F3, where it loops if stand by (Y) or continues to F4 if not (N) stand by. When going to electronic mail F4 and a negative signal is given, the procedure goes to sheet-counting charged mail F5 and then if a negative signal is given, the processing goes to standard mail F6. In F4, if a positive signal is given, the procedure goes to F73 for electronic mail command input. When a positive signal is given in F6 by means of pressing a &#34;standard mail&#34; key, the microprocessor 10 then commands the system to operate according to the preset &#34;standard mail&#34; procedure. The standard mail is thereby sent to a first weighing scale F7. The operator then inputs relevant informations of the standard mail (such as deliverying manner, service division, register, or insured value, etc.) into the microprocessor 10, which thereafter calculates the postage according to these informations via preset programs. If a positive signal is given in bulk mail procedure F10, a bulk mail command must be input to enable the procedure to go to the bulk mail procedure F101. The total postage mail then be displayed on the display 720 in procedure F11. 
     In case of individual standard mail, the procedure will go directly from F9 to F11. After the postage payment procedure F12, all commands are checked for correction, and if so, the actuating key is pressed in procedure F13. At this time, the microprocessor will command the postage stamp device to automatically set the numeral wheels thereof into proper date and postage in procedure F16. When a positive signal is given in standard mail procedure F17, the mail is conveyed to the printing position in mail conveying procedure F18. In procedure F19, the postage is imprinted on the mail. (The mails can be sorted if necessary. This procedure is not shown in FIG. 2B.) Thereafter, the postage stamp device is zeroed in procedure F20. The printer will then print a receipt and certificate in procedures F21 and F22, respectively, and then the above relevant data are stored in procedure F23. Simultaneously, the receipt, money card and other documents are given to the customer in procedure F24 and the whole procedure ends in procedure F25. 
     According to the above procedure, in case of a non standard mail, the procedure will go from F6 to a second weighing scale procedure F71 and relevant commands are input according to identical manner in procedure F81. In procedure F9, the postage is calculated by microprocessor and the procedure goes from F10 to F17. Because of non standard mail, the microprocessor 10 will command the postage stamp device to supply a blank postage label and enter the label into printing position for imprinting from procedure F180 to procedure F190. The following procedure is the same procedure as the above-mentioned one and the description thereof is therefore omitted. 
     In case of sheet-counting charged mail, a position signal is given in procedure F5, and a sheet-counting command will be input in procedure F72. When relevant commands respecting the mail are input in procedure F82, the procedure will go from F9 to F13. In F14, if a negative signal is given, the procedure will go directly from F14 to F16 after postage payment, and then go to F17, F18, F19, F20 or F17, F180, F190, F20 according to standard mail or non standard mail procedure. The procedure goes finally to F21, F22 and ends after printing the receipt. 
     As to electronic mail, when a positive signal is given in procedure F4, and the electronic mail command is input in procedure F73, the commands of the mail can be input in procedure F83. Thereafter, when procedure goes from F11 to F13, since weighing is not necessary, the procedure will go directly from F14 to F22 to print the certificate after postage payment. The following procedure is identical to aforesaid one and the description thereof is therefore omitted. 
     To easily understand the postal material-managing process of the present invention, two main portions thereof, i.e., automatic weighing device for conveyed postal material and automatic postage stamp device are described in detail as follows: 
     Referring to FIGS. 3 to 5, one embodiment of the automatic weighing device 23 for postal material in conveyance according to the present invention is illustrated. As shown in FIG. 3, the device 23 of the present invention comprises a conveying device 30, which includes a driving means 300, for example, a motor, a first conveying means 301A and a corresponding first idle wheel 310 thereof, a second conveying means 301B and a corresponding second idle wheel 201A, a third conveying means 301C and a corresponding third idle wheel 201B, a fixed stand 400, a movable stand 200 with a pair of rocking arms 120 (see FIGS. 4 and 5), and a weighing scale 500 located under the movable stand 200, and a first sensor S1 located before the first conveying means 301A (see FIG. 4) and a second sensor S2 located after the third conveying means 301C. 
     A novel aspect of the present invention is the movable stand 200 that includes a supporting stand with a rectangular opening 208 in the middle portion thereof. At both ends of the opening 208 there are disposed the second and third idle wheels 201A and 201B that are in cooperative relationship with the second and third conveying means 301B and 301C respectively to convey a standard mail L to be weighed. 
     Referring to FIG. 4. A movable end 122 of each of a pair of front and rear rocking arms 120 is pivotally connected at each end of the movable stand 200. The other end 121 of each rocking arm 120 is pivotally connected at a pivot 101. A pair of electromagnetic actuators 100, such as a solenoid, is connected to the middle portion of the front rocking arm 120. When the electromagnetic actuator 100 is activated, the movable end 122 is pulled down with the pivot 101 as a fulcrum. Since the moving stand 200 is attached to the movable ends 122 of both of the rocking arms 120, both movable ends 122 are actuated and descend simultaneously to move stand 200 to a lower horizontal plane. As best shown in FIG. 4, the second and third idle wheels 201A and 201B are connected to move with the movable stand 200 in vertical planes corresponding to the second and third conveying means 301B and 301C, respectively. The first conveying means 301A precedes the second conveying means 301B. The driving means 300, e.g. a stepping motor, drives the first, second and third conveying means. The first conveying means 301A is urged by a pair of first pulleys 302 (FIG. 3) and a first conveying belt 303 thereof. Referring again to FIG. 3, the second and third conveying means 301B, 301C are respectively urged by a pair of second pulleys 304, a second conveying belt 305, a pair of third pulleys 306, and a third conveying belt 307. 
     Disposed beneath the opening 208 of the movable stand 200 is the weighing scale 500. A weighing plate 501 of the weighing scale 500 is positioned above the main body of the weighing scale with its surface a little lower than the movable stand 200 so that the weighing plate 501 does not obstruct the conveyance of the article to be weighed. 
     The operation of the weighing device 23 of the present invention can best be understood by referring to FIGS. 3 through 5. Prior to reaching the first conveying means 301A and first idle wheel means 310, mail L comes in contact with the first sensor S1, such as photo-sensor, and the driving means 300 is actuated to convey mail L to a position to be weighed, as shown in FIGS. 4 (initial position) and 5 (weighing position). In the positions shown in FIGS. 4 and 5, the electromagnetic actuator 100 is not activated. Therefore, the movable ends 122 of the rocking arms 120, due to the force of the springs 104, urge the second and third idle wheels 201A, 201B upward and in close contact with the second and third conveying means 301B, 301C, whereby the mail L can be delivered onto the movable stand 200 as shown in FIG. 4. 
     When the mail L reaches the front edge of the second sensor S2, the second sensor S2 sends a sensor signal to actuator 100. The electromagnetic actuator 100 is thereby activated and the movable end 122 of the related rocking arm 120 is pulled down lowering movable stand 200 and the movable end of the other rocking arm. The mail L to be weighed is then seated on the weighing plate 501 of the weighing scale 500, as illustrated in FIG. 5. The weighing scale can weigh the mail L, and display the result on the display means of the weighing scale 500 via microprocessor 10 or send out a signal to perform some other control functions. 
     After a pre-set time period following measurement of the object&#39;s weight, the electromagnetic actuator 100 will be deactivated, and both rocking arms 120 are drawn back by the force of the springs 104 and the movable stand 200 is restored to its initial position. The mail L, having been weighed, is again held between the second and third idle wheels 201A, 201B and the second and third conveying means 301B, 301C, and thus continues to be conveyed into digital mark-printer 25. 
     It should be emphasized that by using this invention the mail L is weighed automatically in conveyance and in weighing position, the movable stand 200 is indicated to descend, preventing the mail L from contacting other portions and the result can be transmitted to a computer for analysis via the weighing device interface circuit 12. After weighing, the movable stand 200 automatically returns to its home position. 
     Turning now to FIGS. 6 to 9, an embodiment of the postage stamp device 25 of this invention is shown. The printer 25 includes a conveying system and a postmark printing system wherein the conveying system is arranged above and below a conveying reference surface A1, including a main driving means of the conveying system, for example, a first stepper motor 251, driving a first roller 2512 and a second roller 2513 through timing belts 2510 and 2511 respectively, as shown in FIG. 6. Referring to FIG. 6, there are installed an idle roller 2514 with a stretching spring above the first roller 2512 and an idle roller 2515 above the second roller 2513. The post mark printing system is shown in FIGS. 6 and 7, including a main shaft driving means 256 e.g. a second stepper motor 256, pulleys 2561, 2563, a timing belt 2562, a main shaft 2505, on which a plurality of second racks 2504 are slidably mounted, a plurality of stepper motors 253A, . . . 253H for driving their respective numeral wheels 271, 272 through their respective related gears means 253A4 . . . 253H4, ink-printing means 40, a printing head 27, and an idle roller 2516 thereof (see FIGS. 6, to 9). The printing head 27, as seen in FIG. 8, includes a postmark wheel means 271 for imprinting postage, a postmark wheel means 272 for imprinting accepted date, a graphical postmark means 273 for imprinting advertising marks. 
     Referring to FIG. 7, the postmark wheel means of postage 271 further comprises a numeral wheel 2711, a gear 2712 attached therewith, a first rack 2713 engaged with the gear 2712, a guiding bar 2714 for a first rack 2713 to move thereon, and a hooking arm 2715. The lower end of the hooking arm is secured to a recess 2506 of a second rack 2504. In order to restore the main shaft 2505 to its home position after the completion of postmarking, an encoder 234A and a main driver sensor 234 are disposed near the driving portion of the second stepper motor 256. Similarly, in order to assure that the stepper motor 253A properly drives the corresponding character wheel 2711, an encoder 253A1 and a first wheel driver sensor 231 are disposed thereon. 
     Prior to the entering of postal material into the conveying system, the printing head 27 is zeroed to its home position (not shown) wherein the motor 251 is the prime driving source of the conveying system. As shown in FIG. 9, disposed between the first roller 2512 and printing head 27 is a sensor S6 whereby after a postal material L passes through the sensor S6, the processor 10 will actuate the printing head 27. Below the printing head 27 is a third idle wheel 2516 with stretching spring in order that the postal material L have a close contact with the numeral wheel 271 of the printing head 27, as shown in FIG. 9. 
     As to the inking to be applied to the numeral wheel 271, it will be carried out by the printing ink means 40, as shown in FIG. 9. The ink means 40 includes an ink tank 45, a first roller 44A, a second roller 47, a third roller 41 and an adjusting means 48. The ink means 40 pertains to prior art and the description thereof is therefore omitted herein. 
     As can be seen in FIG. 9, when the postal material L is forwarded to be printed by the printing head 27, due to the spring effect of the first, second and third idle wheels 2514, 2515, 2516 the printing effect is equally excellent regardless of the thinkness of the printed postal material. This should be considered as an advantage of this invention over prior art. 
     The disclosure going thus far is made only with respect to a printing head with one numeral wheel, in practical operation, however, the device works with four numeral wheels or more than four numeral wheels arranged as two or more than two parallel sets, wherein one set functions as date numeral wheel, the other as postal charge numeral wheel, as shown in FIG. 8. Various arrangement between the stepper motors 253A-253F and their related second racks 2504A-2504F for each set of character wheels can be arranged easily. As can be understood, more character wheels mentioned above can be arranged in accordance with the need. 
     It has to be pointed out that a relatively smaller diameter portion 2505B of the main shaft 2505 of the printing head is in alignment with that where the driving gear 253A4 is located, as shown in FIG. 7. It will be seen from the drawing, the outer perimeter of the relatively smaller diameter portion 2505B, just comes flush with the dented base 2502 of the second rack 2504, so that after respective stepper motors 253A-253N are located at their proper positions and the main shaft 2505 of the printing head rotates, the second racks 2504 and the relatively smaller diameter portions 2505B can slip through the driving gear 253A4. In other words, the second rack 2504 for driving the character wheels of the printing head 27 can slide axially along the main shaft 2505, and also can rotate together with the main shaft 2505 after reaching its proper position, thus smoothing the work of the printing head 27 and reducing the very complicated machanism as needed in the cases of prior art work. This should also be concluded as one of the most important feature of this invention. 
     To further understand the present invention, the automatic mail-processing system thereof is described as a whole as follows: 
     Please refer to FIGS. 10 to 12, which illustrate the appearance of the present invention. The front portion of the main body H of the automatic mail-processing system is faced to the postal clerks, while the rear portion thereof is faced to the customers normally. A guide rail 309 for bulk standard mail is disposed on the left front portion of the main body H. On the right side of the guide rail 309 is disposed a mechanism center M. Above the mechanism center M is located a first display device 720, and after the center M is located a second display device 720A. The mechanism center M includes the automatic conveying device 30, the first weighing scale 500 and settable automatic postage stamp device 25. On the right side of the mechanism center is disposed a collecting tank 21 for collecting processed postage label and bulk mails. Adjacent to the tank 21 is disposed the second weighing scale 500A. The weighing scales of the present invention are electronic weighing scales applying load cells as weight sensors. The second weight values are converted and displayed on the first and second display devices 720, 720A via the weighing scale I/F CKT 12 and microporcessor 10. To reach the object of communication between postal clerks and customers, the two display devices 720, 720A are disposed respectively on the front and back sides of the mechanism center to show the data about mail weight, postage calculation, postage payment, and other inner state indications (such as insufficient ink, lack of postage label, over weight, etc.) on both the first and second display devices 720, 720A. 
     As shown in FIG. 10, a key board system 70 is located on the front upper right portion of the main body, including domestic mail command input key board 730, international mail command input key board 740, bulk mail command input key board 750 and actuating key 770. On the front left portion of the main body is disposed the money receiver 710 including the card reader/writer 711, holding key 712, accumulating key 713 and cash key 714. On the front right portion of the main body is disposed the printer assembly 780 including receipt printers 782, 781, finacial list printer 783, etc. A power switch 760 is located on the left side of the printer assembly 780 to control the operation power of the present invention. Furthermore, a facsimile 600 is located at the right end portion of the main body for transmission of the electronic mails. 
     Please now refer to FIG. 13, which illustrates the mechanism center M of the present invention. The mechanism center M essentially includes the automatic weighing device 23 and automatic postage stamp device 25, which have been described in preceding paragraph. 
     It should be noted that to prevent mails with abnormal length from affecting the normal operation of the present invention, a set of sensors S1 to S5 are provided whereby when a mail enters the system and is sensed by sensor S1, and the driver 300 consequently rotates to convey the mail forward, if sensor S2 senses the mail while sensor S3 does not sense, it indicates a too short mail, then the driver 300 will reversely rotate to reject the mail. Moreover, when sensor S5 senses the mail while sensor S1 remains in sensing condition, a too long mail is indicated and the driver 300 also reversely rotates to reject the mail. Therefore, mails not meet length regulation will be removed in advance. This arrangement is a characteristic of the present invention. 
     As shown in FIG. 13, this embodiment of the present invention is generally identical to the embodiment shown in FIGS. 3 to 9. However, the first conveying means 301A, first idle wheel 310 thereof, first pulley 302 and second pulley 304 are omitted in this embodiment, and a direct driving manner is applied therein.

     7. As described above and shown in FIGS. 1 and 2, the microprocessor is the operation center of the present invention, wherein the CPU and EPROM thereof are provided with programs recording the required postage table, postage calculation manner, sorting of delivery area and postage calculation, managing manner of bulk mail, sheet-counting charged mail calculation manner, receipt and income list and inner/outer operation manner in advance, whereby via the key board system 70, the operation, control, check, calculation, judgement, analysis, execution, performance, datum storage, printing, etc. of the present invention can all be practiced conveniently. Therefore, the present invention can serve as a completely intelligent automatic mail-processing system with full functions. 
     To best understand the aforesaid functions of the present invention, an example is set forth as follows: 
     If a mailer wants to send an insured express air mail with standard envelope to France, when the mailer passes the mail to a postal clerk, as shown in FIGS. 10 and 15, the clerk can depress the standard mail key 7401 on the international key board 740, the air mail key 7405 thereof, mail key 7408, express key 7419, insure key 7420, and Europe/Africa/Middle South America key 7424 thereof, and then depress actuating key 770 to complete the command input. At this time, the mail L will be automatically conveyed to the weighing are a by the automatic conveying device 30 (see FIGS. 4, 5, and 13). When the mail L reaches the sensor S4 located at weighing area, the movable stand 200 of the automatic weighing device 23 descends under commands from microprocessor 10 to set the mail L on the weighing plate 501 of the first weighing scale 500 (see FIG. 5). The mail is thereafter weighed by the first weighing scale 500 without contacting any other portion. After weighing, the movable stand 200 of the weighing device 23 automatically returns to its home position to lift the mail L to original level (as shown in FIG. 4). In the meanwhile, the postage, being accurately calculated by microprocessor, is displayed on display device 720, 720A to show the mailer the proper postage. If the mailer want to pay the postage with money card, he can insert the money card into card reader/writer 711. The balance is then displayed, and the postage is substracted therefrom. A new balance is thereafter written on the card by card reader/writer 711. The card is then rejected therefrom. If the last balance can not pay the postage, the card will be rejected from the card reader/writer after the balance is totally substracted. The mailer then can depress the holding key 712 and insert a new money card. If the mailer wants to pay the due postage in cash, the postal clerk can depress cask key 714 after receiving the money to complete the postage payment procedure. 
     In the meantime, when the mail L is conveyed to postage stamping area by conveying device 30 as shown in FIG. 9, the mail L will be further sent into the stamping area by rollers 2514, 2512 of the postage stamp device 25. When the mail is detected by the sensors thereof, the numeral wheels 271 thereof (see FIG. 7) are set to proper postage and date positions according to commands from the microprocessor. When the mail L reaches a predetermined position, the printing head 27 is rotated to imprint the set postage and date marks thereon, and the mail-processing operation is then accomplished. The receipt printers 781, 782 of the printer assembly 780 will automatically print the receipts and certificate, and the relevant data are stored in the microprocessor. Additionally, an income list will be printed regularly. 
     Please now further refer to FIG. 10. Another example is set forth for further understanding the operations of the present invention. Supposing a mailer wants to mail an air small packet to the United States, since the small packet is not standard mail, and can not be stamped with postage stamp directly, a postage label is necessary to be attached to the small packet. Therefore, when managing the small packet, it must be first placed on the second weighing scale 500A to show its weight on the display devices 720, 720A. Thereafter, the necessary commands are input into the microprocessor via key board system 70. Referring to the international key board 740 as shown in FIG. 15, the non standard mail key 7402, air mail key 7405, small packet key 7411 and North America 7445 thereof are depressed, and in case of additional services, the insure key 7433 of the additional service key board is depressed. Consequently, the due postage is immediately displayed on the first and second display devices 720, 720A. The other procedures are identical to the aforesaid ones except that the postage label is supplied by postage label supply device 60 of the postage stamp device 25 as shown in FIG. 13. After imprinted with postage stamp, the postage label is sent out of the rear end of the postage stamp device 25 to the collecting tank 21. The postal clerk then can attach the label to the air small packet. Simultaneously, the receipt printer 781 will send out a double receipt wherein the lower two sheets together with the postage label attached to the small packet while the lower sheet of the upper two sheets is given to the mailer and the upper sheet thereof is attached to a check record of the clerk for later inquiry.
