Abstract

PURPOSE:To obtain a small-sized, inexpensive device by providing both a label printing function and a sheet printing function to one printer that a main body is equipped with. CONSTITUTION:A cassette loading part 3 is so constituted as to load a cassette 4a which contains label forms and a cassette 4b which contains receipt forms selectively on the postal scale main body 2. The cassette printer prints data on both forms 8 and 9 in the cassette 4a and 4b. Further, the cassettes 4a is provided with an opening part 31 so as to discriminate the kinds of forms stored in the cassettes 4a and 4b respectively. Consequently, when the cassette 4a and 4b are mounted selectively on the main body 2, the loading part 3 recognizes the opening part 31 to judge the kind of the forms in the loaded cassette and switch the printing mode between the forms 8 and 9. The one printer mounted on the main body 2, therefore, prints data on both label forms 8 and receipt forms 9 in those cassettes.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is based on the weight of a weighed item, a set rate,
Regarding Postal Scale, which calculates and displays postage charges based on service, delivery area, etc.

``Prior Art'' Conventional postal scales have a function that simply calculates and displays postage charges based on the weight of the weighed item, set rate, service, delivery area, etc.

Therefore, in order to print certificate stamps and labels on which postal charges are printed, a dedicated printer configured separately from the postal scale is used. The printers used include a journal printer for printing the data of issued certificate stamps and labels on receipt paper, and a printer for printing certificate stamps and labels, and each of these printers is equipped separately. There is.

[Problems to be solved by the invention] Conventionally, mail items were weighed, the charges were calculated,
Two devices, a postal scale and a printer, are required to perform a series of processes such as issuing certificate stamps and labels with the fees printed on them and further printing a journal of data on the issued certificate stamps and labels. As a result, the entire device is extremely expensive, and its placement location is also restricted.

It is an object of the present invention to provide a smaller and less expensive postal scale that enables the series of processes described above to be carried out in one device.

[Means for Solving the Problems] The postal scale according to the present invention calculates and displays the postage cost from the weight of the weighed mail item, the set rate, service, delivery area, etc. A cassette for storing receipt paper and a cassette for storing receipt paper are configured, and the postal scale body is provided with a cassette mounting section for selectively mounting the cassette, and the cassette mounting section is provided with a cassette for storing the cassettes mounted in the cassette mounting section. The cassette printer is equipped with a cassette printer that can print on both label paper and receipt paper, and this cassette printer outputs the postage charge of the mailed item as print data on the label paper, and also stores the print data. The apparatus is characterized in that a control means for outputting the stored data as print data on the receipt paper is connected.

[Function] By replacing and mounting the label storage cassette and the receipt storage cassette on the postal scale main body of the present invention, one printer installed in the main body of the postal scale can handle both the label paper and receipt paper of those cassettes. Performs printing function.

[Example code] Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a perspective view showing the appearance of a postal scale according to an embodiment of the present invention, and FIG. 2 is a block diagram showing the electrical configuration. First, the mechanical configuration will be explained.

In FIG. 1, reference numeral 1 denotes a weighing section composed of a plate-shaped weighing pan, a load cell, an A/D converter, and an interface circuit, and the weight signal corresponding to the weight of mail is sent to the main body 2. supply to. A cassette mounting section 3 is provided on the right side of the main body 2, and a paper cassette 4 is mounted in this cassette mounting section 3. Further, on the front surface of the main body 3, a display section 5 consisting of a dot display or the like, an operation section 6 consisting of a flat keyboard, etc. are provided.

A mode changeover switch 7 is provided on the left side of the main body 3 (see FIG. 3).

Each of these components will be explained below.

There are two types of paper cassettes 4: a label cassette 4a containing label paper, and a receipt cassette 4b containing receipt paper. FIG. 13(A) shows an example of the receipt paper 8 contained in the receipt cassette 4a, which is a roll of thermal paper of a predetermined width. Also. FIG. 2B shows the vicinity of the end of the label paper 9 contained in the label cassette 4a, in which thermal labels 11, 11. ...... is pasted and wound into a roll. Here, between each label 11, there are about 21 detection slits 12, 12...
* is formed, and a terminal end portion 13 on which nothing is pasted is provided at the rear of the final label 11. In this way, the detection slits 12, 12, . . . are provided when printing on the label 11. This is because it is necessary to confirm the position of the This detection is performed, for example, by passing the label paper 9 between a light emitting element and a light receiving element of a transmission type photoelectric sensor, and based on the resulting change in the output signal of the light receiving element.

FIG. 5 is a perspective view showing the structure of the label cassette 4a;
FIG. 6(a) is a rear view of the cassette, and FIG. 6(b) is a diagram showing the internal structure of the cassette 4a.

The label cassette 4a stores label paper 9 inside a shallow box body 21, and when the lid 22 is opened, the label paper 9 is stored inside a shallow box body 21.
It is now possible to store.

Here, the label paper 9 is fitted and attached to the rotating shaft 23,
After passing through the U-shaped guide plate 24 and the idle rollers 25 and 26, the platen roller 27. It passes through the dispenser 28, where the label 11 is peeled off from the backing paper IO, the label 11 is ejected to the outside, and the backing paper 10 is wound up on a take-up reel 29. A prism accommodating portion, which will be described later, is formed at the lower end of the guide plate 24, and a prism 30
is stored. Further, an opening 31 indicating that the cassette is a label cassette is formed on the rear surface of the cassette 4a, and a protection plate 32 is provided on the lower front surface.

Further, on the outside of the lower surface of the cassette 4a, as shown in FIG. 7, a gear 33 fitted to the shaft of the platen roller 27,
A gear 34 fitted to the sleeve of the take-up reel 29 is disposed, and the cassette 4a is attached to the cassette mounting portion 3 of the main body 2.
When attached to the body 2, these gears 33 and 34
It meshes with the drive gears 35 and 36 on the side, and the platen roller 2
7 and the take-up reel 29 are driven to rotate. in this case,
The drive gear 35 is driven by a pulse motor 37,
The platen roller 27 is driven at a constant speed, while the drive gear 36
is driven by a DC motor 38 for winding up the mount, and rotates the winding reel 29.

On the other hand, an example of the structure of the receipt cassette 4b is shown in FIG. This cassette 4b differs from the label cassette 4a described above in that it has an opening 31. There are no idle rollers 25, dispensers 28, and take-up reels 29, and there is a cutter C. This cassette 4 does not have an opening 31.
b indicates a receipt cassette, and the reason for the absence of the dispenser 28 and take-up reel 29 is that in the case of receipt paper, it is ejected to the outside immediately after printing, so the backing paper 10 and label 11 may peel off or the backing paper 10 This is because winding is not necessary. As a result, the receipt paper 8 fitted and attached to the rotating shaft 23 is sent to the outside via the guide plate 24, the idle roller 26, and the platen roller 27. In this case, the platen roller 27 is driven to rotate in the same manner as in the case of the label cassette 4a described above, and the receipt paper 8
Let out. Note that the cutter C is used to pinch and cut the printed receipt paper.

9 and 1O show the cassette mounting section 3 on the main body 2 side, and FIG. 1t is a plan sectional view showing the state when the label cassette 4a is mounted on the cassette mounting section 3. In these figures, TH is a thermal head that performs thermal printing on receipt paper 8 and label paper 9 while pressing them against platen roller 27. In the case of label printing, the printed label 2 is peeled off by the dispenser 28 and discharged to the outside. Sl, S2
is a reflective photoelectric sensor, which indicates that a cassette has been installed, and that the installed cassette is label cassette 4.
This is for detecting whether it is the receipt cassette 4b or the receipt cassette 4b. When the label cassette 4a is installed, the photoelectric sensor Sl receives reflected light and turns on, but the light beam output from the photoelectric sensor S2 is transmitted through the opening 31.
The photoelectric sensor S
2 is off. On the other hand, the receipt cassette 4b
In the case of , since there is no opening 31, the photoelectric sensors Sl, S
2 is turned on in the same way.

FIG. 12 is a sectional view taken along the line ■--■ in FIG. 11, and shows the configuration of the prism 30. This prism 30 bends the light emitted from the light emitting element S3a of the photoelectric sensor S3 attached to the main body 2 side in a U-shape, and the light that has passed through the label paper 9 or the receipt paper 8 is received by the photoelectric sensor S3. The light is reflected so as to reach the element S3b. In this way, light corresponding to the thickness and transmittance of the sheet passing through the guide plate 24 is received by the light receiving element S3b.

Next, the configurations of the display section 5, operation section 6, and mode changeover switch 7 mentioned above will be explained.

As shown in FIG. 4, the display section 5 includes a message area 5-1 for displaying various messages, a weight display area 5-2 for displaying the weight of mail items, and a charge display area 5-3 for displaying postage charges. , a display area 5-4 for bit-displaying information such as the status of the device and the name of the postal company with the rate currently used for calculating charges, and a drive circuit for driving the display mechanism in these display areas. Here, the display areas S-t and 5-2 are constituted by liquid crystal bit displays, and are capable of displaying arbitrary numbers, characters, symbols, etc. Further, the display area 5-3 is composed of a 7-segment display, and the display area 5-4 is composed of a light emitting diode.

The operation unit 6 consists of a flat keyboard 6-1 consisting of a numeric keypad and function keys, a preset key 6-2 for specifying the rate and service type, and a circuit that generates key data KD corresponding to these keys. has been done. The preset keys 6-2 consist of 27 keys rA-ZJ and "-", and are also used for manual input of character data.

The mode selector switch 7 is used to switch the postal scale into three modes as shown in FIG. PROG MODE) and registration mode (which measures the weight of mail by placing it on a postal scale and calculates the fee).
OP MODE) and a test mode (TEST MODE) for practicing and confirming Postal Scale operations.
It is.

Next, the electric circuit shown in FIG. 2 will be explained.

In the figure, 40 is a CPU (central processing unit), and 41 is a measuring section. This weighing section 41 includes the weighing pan 1 shown in FIG.
It is composed of an A/D converter that outputs the signal as D to the pass line B (FIG. 2). The operation unit 6 outputs key data KD corresponding to the key to the pass line date. Display data from the CPU 40 is supplied to the drive circuit of the display section 5 .

The ROM 42 stores a label printing program, a transaction data printing program, a preset data printing program, various character (including numbers, symbols, etc.) patterns (dot patterns), charge tables, control programs, and the like.

The stored character patterns include relatively large character patterns mainly used for printing on labels and several relatively small character patterns used mainly for printing on receipt paper. Each character pattern is assigned a character code, and each character pattern is read out based on this character code. Further, the charge table stores rates and service charges for each postal company. For example, in a table that stores rates, weight categories are plotted vertically and zones (area categories) for each destination are plotted horizontally, so that charges can be calculated from weight and zone. On the other hand, in the table storing service charges, service charges for each postal company are stored, for example, corresponding to the table number.

Next, 43 in FIG. 2 is a RAM, which is composed of (1) print buffer area, (2) preset data area, (2) transaction area, and (2) working area.

The print buffer area (2) is an area in which a character pattern to be printed on a label or receipt is written, and has a size and capacity corresponding to the maximum print section of the label.

The preset data area (2) includes a preset key area and a lookup data area, and the former preset key area consists of the 27 preset keys 6 in
-2, and lookup numbers (numbers 1 to 99) for searching lookup data areas are set in these areas.

For example, in the first area, the A of preset key 6-2 is
A lookup number N002 corresponding to the key is stored, and a lookup number No. 1 corresponding to the B key is stored in the second area, and so on.

On the other hand, the latter lookup data area has an area on the 99 side corresponding to lookup numbers rlJ to "99", and each area can store up to five table numbers of rate tables. There is. Note that in these areas, a rate table number of 1 or 0 and a service charge table number of 0 to 5 can be set. This is because, while it is meaningless to specify two or more types of rates when calculating charges, there are various additional services. In the transaction area (2), the next toNl data regarding the 150 items of the latest processing data is stored in a fixed word length (sequential file).

■Number (serial number = 1 to 150) ■Table number of rate (ex, rtrps GROUNDOJ) ■PIN (pub cage IDN0.) ■DPT (publishing department) ■ZONE (shipping area) ■Price 0 weight ■C0D (Payment in advance) service available ■ AOD (notice of delivery) service available [Phase] DV, (insurance) available,
If so, the insurance amount and payment amount or more are summarized as follows.

A lookup number is selected corresponding to each of the 0.27 preset keys 6-2 and set in the preset key area.

A lookup data area having 99 areas is provided corresponding to each of the 0.99 lookup numbers,
The rate table number stored in this area associates the lookup number with the rates and services in the rate table. Furthermore, up to five rate table numbers including rates and services can be set for each of the 99 areas. However, the maximum number of rates is one.

■The rate table stores all expected rates and services in use. Note that the charge table is changed by replacing the ROM 42.

Next, 44 in FIG. 2 is a printer section, and a pulse motor 37, !, which drives the paper. Heating resistor r for 28 dots
A drive circuit 45 for driving a thermal head TH consisting of . Based on the control data supplied from the CPU 40, the interface 47 outputs a drive pulse MCP for driving the pulse motor, a print pulse DP to the drive circuit 45,
A shift pulse CP and serial dot data DATA are respectively output to the shift register 46.

Next, the operations of this embodiment can be roughly divided into a setting operation, a registration operation, a test operation, and a printing operation on receipt paper. Here, the setting operation means writing data to the preset data area.

The registration operation means calculating the charge for a postal item, and includes printing the calculated charge on a label and storing the data printed on the label in the transaction area. The test operation means an operation for practicing or confirming the operation, and includes a test label printing operation for printing a label on a trial basis.

The printing operation on receipt paper means the operation of printing transaction data and preset data on receipt paper, and depending on the printing contents, report mode (when printing transaction data), output mode (
There are two types: charge table data and preset data). These operations can be switched by switching the mode selector switch 7 to position 3 and by switching the cassette mounting section 3.
A total of 6 replacements for the two types of cassettes 4a and 4b installed in the
This is done by a combination of two.

Therefore, prior to explaining the individual operations, switching processing for each operation will be explained. (See Figures 14 and 15).

(2) Start after the power switch is turned on and the initial processing of the device is completed.

■First, set the mode selector switch 7 to program mode (
Check whether it is set to PROG) (
Step St).

■When set in PROG, check whether a cassette is installed in the cassette loading section 3 (
Step S2). This check is performed using the detection signal of sensor S1.

If the cassette is not set, empty processing is performed to set the cassette empty flag (step S3), and the program mode (P-MODE) is set.
) Enter the main routine Ml. This main routine M1
The above setting operation is performed by.

■When a cassette is set, reset the cassette empty flag (step S4) and then
It is checked whether the cassette is the label cassette 4a (step S5). This check is performed based on the detection signal of the sensor S2. If the label cassette 4a is set, the main routine M1 is entered. If the label cassette 4a is not set, that is, the receipt cassette 4b is not set. If so, the report mode (R-MODE) main routine M4-1 is entered. This main routine M4-1 is one that controls the printing operation on the receipt paper.

■, Meanwhile, Step S! If it is determined that the mode selector switch 7 is not set to PROG, it is checked in step S6 whether or not a cassette is mounted in the cassette mounting section 3. The check is step S
As in case 2, this is performed using the detection signal of sensor S1.

When a cassette is not set, a cassette empty message is displayed in the message area 5-1 of the display section 5, and an empty process (step S7) is performed to set a cassette empty flag, and the process returns to step S1.

(2) When a cassette is set, the cassette empty flag is reset and the cassette empty message is erased (step S8), and then it is checked whether the cassette is the label cassette 4a (step S9). This check is performed using the detection signal of the sensor S2 as in step S5.

■When the syllabel cassette 4a is set,
Further, in step SlO, it is checked whether the mode changeover switch 7 is set to the operation mode (OP). When set to operation mode (OP), operation mode (0-MOD)
E) Enter main routine M2 and enter operator mode (O
P), that is, test mode (
T-MODE), the test mode (T-MODE) main routine M3 is entered.

The operation mode (0-MODE) main routine M2 performs the above-mentioned registration operation, and the test mode (0-MODE)
T-MODE) The main routine M3 performs the test operation.

■, In the check in step S9, label cassette 4
When label cassette 4b is not set, that is, when label cassette 4b is set, first mode (L-MO
DE) Enter main routine M4-2. This main routine M4-2 is another one that controls the printing operation on the receipt paper.

The above relationships are summarized in FIG. 15. In the figure, L
C is the label cassette 4a, RC is the receipt cassette 4, and bSEMP TY means that no cassette is set. As is clear from this figure, the five main routines M
l, M2, M3, M4-1. Switching of M4-2 is performed.

Next, the above-mentioned individual operations by these main routines will be explained.

(1) Setting operation This setting operation is performed in program mode (P MODE).
This is carried out by inputting necessary data from the operating section 6 in the main routine M1.

In this case, first set the rate table number and service charge table number in the ROM 42 in the lookup data area in the preset data area of the RAM 43, and then set the lookup number in the lookup data area in the preset key area in the preset data area. Set to . This setting operation is performed interactively while viewing the message displayed in the message area 5-1.

The procedure is summarized as follows.

■First, according to the message, enter the numbers "1" to "99" as the lookup number on the flat keyboard 6.
Manually specify the lookup data area using the -1 numeric keypad.

00 Next, enter the table number of the rate and the table number of the service charge in the message, and set them in the lookup data area specified in (■). As mentioned above, up to five rates and services can be set in each lookup data area, and the maximum rate is one.

(2) After setting the child table number, write a message and set the lookup number of the lookup data area in the 27 preset key areas corresponding to the preset key 6-2.

This completes the setting operation.

(2) Registration operation This registration operation is performed in operating mode (0-MODE).
) In the main routine M3, the mail is placed on the postal scale, the weight is measured, and the fee is calculated.
Includes a label printing operation that prints the calculated fee on the label.

In this case, first, the preset key 6-2 is pressed to select a rate or service, and the charge is calculated from the selected rate, service, and weight. When calculating charges, if it is necessary to specify a destination, it is done manually using the numeric keypad. In the United States, the destination instructions are postal codes (z
tp) or a zone number; since the zone number is one digit and the postal code is multiple digits, it is determined that it is a postal code when the number of digits is input. When a postal code is designated, a zone number is determined from the postal code using a conversion table stored in the ROM 42.

Such registration operation can be summarized as follows.

■Place the cargo between the weighing pans. As a result, the measuring section 41
measures the weight, and the result is displayed in the weight 1 display area 5-2. Note that this measurement may be performed later.

■In order to read the charge data according to the package, first,
Press the preset key 6-2 to select the corresponding ROM
The lookup number is read from the lookup key area of 42. Then, the lookup data area for that number is searched, the table number of the rate set there and the table number of the service charge are read out, and the table of that number is transferred to the register in the working area of the RAM 43.

(2) The CI'U 40 obtains the charge from the rate table and service charge table transferred to the register. At this time, the CPU 40 requests the operator for the manpower of the destination zone of the package, searches the rate table based on the zone and the weight of the package, and obtains the rate fee. Then, the service charge read from the service charge table is added to the rate charge, the total charge is displayed in the charge display area 5-3, and the operator is requested to input the package number.

(2) After the operator inputs the package number, the label printing operation is started by pressing the print key rPRINTJ. Also, the data in the working area is stored in RAM.
43 transaction area.

(2) In the label printing operation, first read the information in the working area of the RAM 43 according to the label printing program in the r(0M42), and convert it into a character pattern using the character pattern in the ROM 42.
The character pattern is written in the print buffer area in the RAM 43 in the same arrangement as the character arrangement when printing the label.

(2) Then, the contents of the print buffer area are sequentially output to the printer section 44. As a result, the printer section 44
The label is printed.

Therefore, in the following, the operation of the printer section 44 will be explained as follows.
This will be explained with reference to Figure 6 (a).

(2) First, one line of data developed on the screen memory is set and printed (step 511).

■After 1942 minutes of printing, it is checked whether printing for one label has been completed (step S12).
. In the case of label printing, since the size of the print area is set, it is checked whether printing in the set area has been completed.

(2) When one label is being printed, the label is fed by one line, the line number is updated (step 513), and the process returns to step Stt.

(2) When printing for one label is completed, the process advances from step S12 to step S14, where the label is fed for one line, and the photoelectric sensor S3 detects the slit (label cap) 12 of the label paper 9 (Fig. ) is detected (step 515).

■ If the slit 12 is not detected, step S1
Return to 4 and feed for another 1942 minutes.

(2) Then, label printing is ended when the slit 12 is detected.

In the case of label printing in this way, the printing operation for one label is completed based on the detection signal of the charging sensor S3.

An example of label printing is shown in FIG. 17(a). In the figure,
51 is the rate, 52 is a symbol indicating the issuing office, 53 is the package number, 54 is the label issue date, 55 is the weight, 56
is the zone, and 57 is the postage fee.

(3) Test operation This test operation is an operation in which the charge is calculated and the calculated charge is test printed on a label in the test mode (T MODE) main routine M4.

This test printing is similar to the setting operation described above, except that the characters 58 rTEsTJ are printed on the label and the data is not stored in the transaction area of the RAM 43. Display area 5-4 indicates that it is test printing.
This is displayed when the indicator lamp "TESTJ" is lit.

An example of test printing is shown in FIG. 17 (b).

(4) Printing operation on receipt paper As mentioned above, the printing operation on receipt paper is the operation of printing on receipt paper by main routine M4-1 and main routine M4-2. The printed content is different. Therefore, I will explain them separately.

(4-A) "Printing operation by main routine M4-1" In this case, the report mode (R-MODE) is set, and IIAM4
The contents of the transaction area in step 3 are printed on the receipt. In this mode, "report mode" is displayed on the display section 5.

In this mode, data in the transaction area can be printed in various report formats.

The report includes the following:

■Data of all 150 items in the transaction area.

■, Report only for C0D (delivery and pay-as-you-go service).

■, DV (insurance service) only report.

■, AIR (airmail) only report.

■Other various reports.

A report number is assigned to each type of report, and after the report number is entered manually, receipt printing is executed by pressing the print key rPRINTJ. During printing, the type of report is displayed on the display section 5.

The operation of the printer unit 44 in such a report mode will be explained with reference to FIG. 16(b).

(2) Steps Sll and 12.13 are the same as in the case of label printing shown in FIG.

■When printing for one label is completed, the process proceeds from step S12 to step SI6, where a timer is set,
Then feed the label by one line (step S
l7).

(2) Check whether the timer has timed up and turned on (step 518); if not, return to step S17; if turned on, print the receipt.

In the case of printing on receipt paper in this manner, the printing operation is completed by feeding the receipt for a certain period of time.

An example of printing in the report mode is shown in FIG. 18(a). What is shown is! The item number of the report printed with all 50 items is "29" to "35".
” part.

(4-B) "Printing operation by main routine M4-2" In this case, the list mode (L-MODE) is entered, and the rate and charge table in the ROM 42 and the contents of the preset data area in the RAM 43 are printed on receipt paper. In this mode, "list mode" is displayed on the display section 5.

In this mode, various list formats can be printed. The list includes:

■List of remembered rates and service types.

■List of rates in the lookup data area.

(2) A list of lookup numbers corresponding to alphabetic preset keys 6-2.

Contrary to ■ and ■, a list of preset keys 6-2 corresponding to lookup numbers.

A list number is assigned to each type of list, and after the list number is input, receipt printing is executed by pressing the print key rPRINTJ. During printing, the type of list is displayed on the display section 5.

The operation of the printer section 44 in such a first printing mode is the same as in the case of report printing described above (16th
Figure (b)).

An example of printing is shown in FIG. 18(b). Shown is a list of stored rates and service types, with table No. (nEsOURcE) ranging from “Ol” to
This is the "12" part.

[Effects of the invention] As explained above, the postal scale of this invention has the following effects:
Since the printer provided in the main body 2 has both a label printing function and a printing function on receipt paper, the following effects are achieved.

■Since the two devices, the Postal Scale and the printer, have been integrated, the housing, power supply, operation section, display section, control section, storage section, etc. can be made common, reducing the number of parts and reducing costs.
