Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention measures the weight of an article, calculates the price of the article by multiplying the measured value by data such as a unit price, and prints it on a label. The label printer that is configured to do.

[Prior Art] In recent years, pack sales of meat, vegetables, and the like have increased remarkably, but it is a labor-intensive process to price them. Therefore, when a pack is weighed, the label printer having a function of multiplying the unit price data stored in the internal memory by the measured value to calculate the price and automatically printing the price on the label is widely used. (See JP-A-60-120223).

In this type of label printer, the unit price data stored in the internal memory indicates whether it is the unit price per 100g or the unit price per kg, or whether the barcode type is 13 digit JAN or 8 digit JAN. The specifications such as bar code type that indicates such things vary depending on the destination etc., so as to cope with these, arrange a dip switch on the printed circuit board and set these appropriately to switch the specifications. I am trying.

[Problems to be Solved by the Invention] By the way, the function of the label printer is complicated, and
As the specifications required by users have diversified, the number of DIP switches has increased, and the following problems have arisen.

The DIP switch occupies a large space on the board, which is an obstacle to realizing a small size, light weight, and cost reduction of the device.

The dip switch must be arranged at a position where the switching operation can be easily performed, which is a great limitation in designing the mechanism.

When the number of DIP switches is large, the switching work is very difficult to perform and is easy to make a mistake.

Since the dip switch is normally switched in the power-off state, whether or not the desired setting can be made cannot be determined until the power is turned on and each function is confirmed. Therefore, in the unlikely event that the user makes a mistake, it must be redone and the workability is extremely poor.

Confirming the specifications that have already been set depends on whether each function is actually checked or the setting state of the DIP switch is checked, but both works are troublesome and require skill.

This invention was made under such a background,
It is an object of the present invention to provide a label printer that can easily set various specifications.

[Means for Solving Problems] In order to solve the above problems, the present invention calculates a price of an article by multiplying the output of the weighing means by a weighing means for weighing the article. In a label printer comprising a calculation means for displaying the calculation result, a display means for displaying the calculation result, and an input means for inputting various data, each specification such as setting of a price of the label printer and setting of a bar code type For each flag provided corresponding to the setting item,
The specification data storage means for storing a value indicating the currently set specification, the secret code storage means for storing a predetermined first and second secret code, and the code inputted from the input means are Judgment means for judging whether or not it coincides with the first or second secret code stored in the secret code storage means, and the above-mentioned specification when the judgment means judges that it coincides with the first secret code. The basic specification setting means for collectively setting the value of each flag stored in the data storage means to a value meaning a standard specification and the judgment means are judged to match the second secret code. In this case, a permission unit that permits the value of the flag stored in the specification data storage unit to be rewritten for each flag by the input data from the input unit, and the input unit. When rewriting the value of the flag stored in the specification data storage means by al data,
Display control means for converting the value of the flag currently set into character information for notifying the specification that the value means and displaying it on the display means, and of each flag stored in the specification data storage means The gist of the present invention is to include a specification determining unit that determines each specification of the device according to the value.

[Operation] According to the above configuration, the first means from the input means (keyboard)
When the personal identification code is input, the basic specification setting means collectively sets the values of the flags stored in the specification data storage means to values that mean standard specifications.

Further, when the second personal identification code is input from the input means (keyboard), the permission means changes the value of the flag stored in the specification data storage means by the input means (keyboard). Rewriting is allowed for each flag. In this case, the value of the flag currently set is displayed on the display means by the display control means as character information for informing the specification of the value.

In the label printer of the present invention, the specification determining means determines various specifications of the apparatus (for example, whether the price is 100 g or 1 kg) corresponding to the value of the flag. Various processes (such as price calculation and bar code printing) are performed based on the specified specifications.

The specification data storage means for storing the value of the flag is
A non-volatile RAM (Non-Volatile RAM: hereinafter referred to as novolum) is suitable.

Embodiments Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing the outer appearance of a label printer according to an embodiment of the present invention, and FIG. 2 is a block diagram showing the electrical configuration of the same embodiment.

In these figures, reference numeral 1 is a weighing unit composed of a weighing pan on a plate, a load cell, etc., and supplies a weight signal with respect to the weight of an article to the main body 3. On the main body 3, a printing unit 4 for printing a label attached to a strip-shaped mount,
A display unit 5 for performing various displays, an operation unit 6 including a flat keyboard and key switches, and the like are provided. Also,
A reflective label sensor 7a is attached to the label discharge port 7 to detect whether or not the label after printing is taken out.

The display unit 5 has a message area 5-1, a weight display area 5-2, and a price display area 5 as shown in FIG.
-3, product number (predetermined number corresponding to the type of article) display area 5-4, tare amount display area 5-5, unit price display area 5-6, number of packs (number of packs of the same article)
The display area 5-7, the weighted display area 5-8, and the like. Each area of each display unit in the display unit 5 is composed of a liquid crystal dot display, and can display arbitrary numbers, characters, symbols and the like.

The operation unit 6 includes a flat keyboard unit 6-1 composed of ten keys and function keys, and key switches 6-2 and 6-3 for switching operation modes of the device.

Returning to FIG. 2, each output signal of the measuring unit 1 and the operating unit 6 is supplied to the CPU 10 via the bus 9. The printing unit 4 also performs thermal dot printing on the label based on the print signal supplied from the CPU 10. As a result, as with the display unit 5, arbitrary printing of characters, symbols, bar codes, etc. can be performed. The display unit 5 is
The display is performed by the display signal supplied from the CPU 10.

ROM11 (PIN code storage means) is a control program,
It is a read-only memory that stores various character patterns, a secret code to be described later, and the like. The CPU 10 functions as the calculating means, the judging means, the basic specification setting means, the permitting means, the display control means, and the specification determining means by executing the control program stored in the ROM 11. In the present embodiment, it is assumed that "177" is set as the personal identification code when the specifications are individually set, and "237" is set as the personal identification code when the basic specifications are collectively set. .

Next, the RAM 12 is provided corresponding to each specification setting item such as a file area in which the product number, product name data, unit price data, etc. are stored, the set price of the label printer described later, the type of bar code, etc. For each flag, a storage area (specification data storage means) in which a value indicating the currently set specifications is stored, a register area for temporarily storing data such as unit price, price, weight and the like are secured. . A nonvolatile RAM (knobram) is used as a storage area for storing the value of the flag.

Next, the operation of this embodiment will be described. In addition, in the present embodiment, it corresponds to each specification setting item such as setting of a quote, setting of each decimal point of weight, unit price, and price (this is used outside of Japan), setting of weighing, setting of bar code type, etc. Flags are provided respectively, and the specification of each specification setting item is selected by appropriately setting the values of these flags. All specification setting items are processed in the same way.
The case will be described.

Before entering the description of the operation, the quote price FT1 provided corresponding to one of the specification setting items, “setting of quote”, will be described with reference to FIG. The standard specifications of quotes are usually in 100g units, but in the present embodiment, it is possible to select and set one of four kinds of quotes, namely, quotes of 10g, 100g, 1000g, 10000g units. There is. And
If the price of the quote FT1 is "1", 10g, "2" is 100g, "3" is 1000g, and "4" is 10000g. It means that Therefore, when the quotation flag FT1 = 2, the unit price data stored together with the product number and product name data in the file area of the RAM 12 is determined as the price per 100 g, and the price of the product is calculated by the weight of the product. It is carried out by multiplying (g) by (unit price data / 100g).

Next, referring to the flowchart of FIG. 5, the quote price flag
The operation of setting the value of FT1 will be described. Note that this setting is done exclusively by the manufacturer.

(1) Set the key switch 6-2 to the date mode. As a result, the date and time are displayed in the message area 5-1 (step S1).

(2) In this state, the CPU 10 has the flat keyboard section 6-
Check for key input from 1. (Step S2). In the case of the normal date mode, the process goes to step S6 through steps S3, 4 and 5 to change the date and time data.

(3) If the user inputs the personal identification code "237" for setting the basic specifications while holding down the "%" key, the input personal identification code is stored in the ROM 11 in step S4 (judgment means). It is determined whether or not the password matches the setting personal identification code, and if it is determined that the password matches, the process proceeds to step S7 (basic specification setting means) to perform a basic specification batch setting process. In the batch setting process of the basic specifications, the value of each flag provided corresponding to each of the above-mentioned specification setting items is collectively rewritten into a value that means a standard standard that is set in advance. I do.

(4) If the user inputs the personal identification code "177" for individually setting the specifications while pressing the "%" key, the entered personal identification code is changed in step S3 (determining means).
It is determined whether or not it matches the personal identification code when individually setting the specifications stored in the ROM 11, and if it is determined that the two match, the process proceeds to step S8 (permission means),
The message "Specification setting mode is ON or OFF?" Is displayed in the message area 5-1 and the specification setting mode is entered.

Here, the knob RAM switch is a DIP switch for permitting / prohibiting the writing of the value of the flag to the nonvolatile RAM, and the writing is permitted only when it is on. The knob ram switch and the secret code provide double protection against the rewriting of the flag value. In addition, when this knob ram switch is off,
The CPU 10 may check this and display "Knob ram switch is OFF. Please turn it ON."
However, the knob ram switch is not essential, but is provided to enhance protection.

(5) Proceed to step S9, and similarly to step S2, the presence or absence of key input is checked. When the quotation flag is set, the "1" and "product number" keys are pressed in sequence, and step S1
The process moves from 0 to step S13. When setting the decimal point for weight, the "2" and "product number" keys are pressed and step S11
Then, the predetermined process is performed, and when the unit price is set to the decimal point, the "3""productnumber" key is pressed and the process proceeds to step S12 to perform the predetermined process. It should be noted that these processes are similar to the processes described later, and thus the description thereof will be omitted.

(6) If the "1" and "product number" keys are pressed and the setting of the quote price is specified, move to step S13 (display control means) and call "price range [1 to 4] 1 / 100G". The display message is displayed in the message area 5-1. Here, the first "price range" indicates that the flag to be set is the quote price, and [1
To 4] indicates the range of flag values that can be specified,
The last "1 / 100G" indicates the specification that the currently set flag value means.

(7) In step S14, the presence / absence of a key input is checked again. Then, in steps S15-18, the value set in the quote price FT1 is checked, and in step S19-22, the above value is written in the quote price FT1. For example, when the "3""productnumber" key is pressed, the quote price FT1 is set to "3".
Is written and 1000g quote is set.

Thus, when the setting of the quote price flag FT1 is completed, the setting contents are displayed in the message area 5-1 (step
S23-26). For example, when the quote price FT1 is set to "3", "price range [1 to 4] 1/10
"00G" is displayed.

It should be noted that, if the regular input is not performed, the process returns from step S18 to step S9, and the above-described processing is performed. Also, to get out of this specification setting mode, switch the key switch 6-2 to another mode,
Carried out.

The label printer of the present invention has various specifications of the device (for example, whether the price is 100 g or 1 kg, corresponding to the value of the flag set in the specification setting mode described above).
It is determined whether or not it is a hit), and various processes (calculation of price, printing of barcode, etc.) are performed based on the determined specifications.

FIG. 6 is a flow chart for explaining a specification determining process for determining the specification of the quote price corresponding to the value of the quote price FT1 described above. Steps SP1 to SP3 in the figure (specification determination means)
Is the step of checking the value of the quote price FT1,
Steps SP4 to SP7 are steps for calculating the price according to the determined specifications. For example, when the price of the quote price flag FT1 is “2”, the unit price data (numerical data) stored in the file area of the RAM 12 by the step SP2 (specification determining means) is 100 g quoted price (price per 100 g). It is determined that there is, the process proceeds to step SP5, and the following formula (1)
The price is calculated by.

P = UP × W / 100 ”(1) where P: Price UP: Unit price W: Weight (g) The same applies to other cases.

It should be noted that the following modifications are possible in the above embodiment.

In the embodiment, only the flag is set, but
It is also possible to set data other than flag setting.
For example, in a special case, 5g unit price cannot be set as a flag, but as a method to deal with this case, the quote price FT1
When "5" is set to, a price calculation program is created to calculate the price based on the contents of the quote price register, and the contents of this register can be set to the same processing as the flag setting operation. May be.

In order to facilitate the setting operation, it is possible to display a message other than that described in the above embodiment. For example, when a CRT is used for display, a menu screen such as a list of setting specifications, a setting method, etc. may be displayed by operating a function key.

[Effects of the Invention] As described above, according to the present invention, specifications such as quotes can be arbitrarily set by input from the keyboard, so that the following effects can be obtained.

It is possible to omit the DIP switch for setting the specifications, and it is possible to reduce the size and weight of the device and reduce the price. Further, it is not necessary to consider the location of the DIP switch for setting the specifications, which facilitates the mechanical design.

Since the specification can be set using the keyboard of the console, the setting operation becomes easy. Also, since the current settings are displayed as text information that means that,
The settings can be made without error. That is, unlike the conventional specification setting using a DIP switch, the complicated work of turning on the power and checking each function after setting the specification with the power off is unnecessary, and the workability is improved. Can be planned.

Although the keyboard used by the user is diverted, the specification setting mode is not switched until the secret code is input, so it is possible to prevent the specification setting contents from being changed by the user's erroneous operation.

If the standard to be set is a standard basic specification, it is possible to collectively set the specifications only by inputting a personal identification code for setting the basic specification. In general, since a large proportion of users have standard specifications, it is possible to set specifications very easily, reliably and accurately in this case. Further, although the specifications required by each user are different, only some of the specifications are different from the basic specifications, and the other specifications are mostly the basic specifications. Therefore, in such a case, after setting the basic specifications all at once, by setting only the specifications different from the basic specifications by key input, the specification setting operation becomes extremely simple and error-free.
