Description

[Detailed Description of the Invention] The present invention relates to a fee scale that calculates the price of an object to be weighed from a weighed value and a unit price.

The price scale includes a weighing section that measures the weight of the object to be weighed, a unit price setting section in which the price per unit weight of the object to be weighed is set, and a weight value obtained by the weighing section and the unit price setting section. It is composed of a calculation section that calculates the price of the object to be weighed from the unit price of the weighing object, and a weight display section, a unit price display section, and a price display section that display the weight value, unit price, and price of the object to be weighed, respectively.

Therefore, in order to obtain a price display with a certain degree of accuracy in the price display section, it is necessary to use the weighing section without overscaling, and the number of digits displayed in the price display section must be
For example, since the price is limited to 4 to 5 digits, it is necessary to confirm that the price calculated by the calculation unit does not exceed the maximum amount that can be displayed.

Therefore, it is conceivable to provide means for notifying the overscale of the weighing section and means for notifying the overflow of the price display section.

However, since there are three display parts for weight, unit price, and price, if over scale display and over flow display are provided separately, it is important to note that over scale and over flow display are not performed. After checking each item, you need to check the contents of the price display section.

This is extremely cumbersome to operate and reduces work efficiency.

SUMMARY OF THE INVENTION Therefore, the present invention provides a rate scale that allows the user to visually check whether the rate is overscale or overflow, without reducing operability.

An embodiment of the present invention will be described below based on the drawings.

The drawing shows a block diagram of the fee scale, in which 1 is a measuring section, 2 is a unit price setting section, 3 is a calculation section, 4, 5.6 is a weight display section, a unit price display section, and a price display section.

l is the weight display section 4 so that the signal Eg corresponding to the weighed value of the weighing section 1 is digitally displayed as the weighed value on the weight display section 4.
A decoder driver that drives the display unit of 8,9
are decoder drivers that similarly drive the unit price display section 5 and the price display section 6 using the signal Ea output from the unit price setting section 2 and the signal EM output from the calculation section 3, respectively.

For example, the decoder drivers γ, 8, and 9 convert the input signals to be compatible with the display, and the lamp test terminals LT> and input terminals for checking whether all segments of the display operate normally. It has a blanking input terminal Bl that turns off all segments regardless of the signal.

10.11 is a digital comparator, and the digital comparator 10 has a reference signal Eg' and a weighing section 1.
The signal Eg at full scale is set, and Eg <E
At g, the output level is inverted to, for example, a logic level 'H', and the other digital comparator 11 receives the reference signal EM.
' The output signal EM of the calculation unit 3 corresponding to the maximum amount that can be displayed by the price display unit 6 is set, and EM'=EM
Then, the output level is inverted to, for example, a logic level "H".

12 and 13 are digital comparators io and i, respectively.
A multivibrator that starts operating when the output level of i is logic level "H", and digital comparators 1o and i
When the output level of i is "H", decoder driver 1,
A lamp test is commanded to the lamp test terminal LT of No.9.

Therefore, in a normal weighing state, the outputs of the digital comparators 10 and 11 are both at the logic level "L", and the weight display section 4 and price display section 6 display the weight value and price.

Further, since the blanking terminal BI of the decoder/driver 8 of the unit price display section 5 is also at the logic level "L", the unit price display section 5 normally displays the unit price set in the unit price setting section 2.

10,000 - If weighing section 1 overscales E g<Eg
In this case, the digital comparator 10 output is at a logic level.”
H" and instructs the blanking terminal BI of the decoder/driver ?8.9 to blank through the OR gate 14, and also outputs the blank to the lamp test terminal LT of the decoder/driver I on the weight display section side. Ranking terminal B
The multivibrator 12 intermittently commands a lamp test even though the blanking state is commanded.

Furthermore, when the price display section 6 overflows, the digital comparator 11 is inverted to the logic level "H",
The lamp test terminal LT of the decoder/driver 9 on the price display side is intermittently kept at the logic level "H" by the multivibrator 13.

That is, when overscaling occurs in the weighing section 1, of the three display sections, the unit price display section 5 and the price display section 6 are set to a blanking state, and the weight display section 4 is set to a specific display, for example, 7.
If it is a segment display, the display "B E23...8" with all segments a to g shown in FIG. When an overflow occurs, the weight display section 4 and unit price display section 5 are set to a blanking state, and the price display section 6 is caused to flash a display of "old aB...day" as a specific display.

Therefore, there is no possibility of reading unreliable prices.

In addition, in the above embodiment, all segments of the display were lit to display "Tomoe" as a specific display, but the weight display section 4
The same thing can be done if a specific signal such as "F" is displayed by the a, e, f, and g segments of the price display section 6, "lH, J" by the *dseyf, etc. of the price display section 6.

As explained above, according to the present invention, only the part that causes erroneous weighing is displayed as a specific display, and the other displays are blanked, making it possible to perform accurate measurements without impairing operability. Since the cause of the measurement can be confirmed at a glance, operations can be immediately carried out to eliminate the cause of the erroneous weighing, thereby improving work efficiency.
