Abstract
A price calculating balance comprises a weighing device 1 whose output is stored in a register 2 and indicated by an indicator 3, an input keyboard 4 for preselecting a unit price which is stored in a register 6 and indicated by an indicator 7, a multiplier for multiplying the contents of registers 2 and 6 for an indicator 9 to indicate the price of the material being weighed, a register 10 for storing a desired total price which is selected on the keyboard 4 and shown on an indicator 11, and a divider 12 for dividing the content of register 10 by that of register 6 for an indicator 13 to indicate the weight corresponding to the desired total price. <IMAGE>
Description
SPECIFICATION
Price calculating balance
This invention relates to a price calculating balance, especially to a novel price calculating balance which can calculate weight of article corresponding to an aimed amount of money.
A so-called price calculating balance for presetting a price per unit weight of article (hereinunder referred to as "unit price") and calculating to indicate the total price through multiplication with measured weight has been known in this field, and is described, for example, in U. S. Patent No. 3,612,842.
Although this price calculating balance is convenient for use when a trade is carried out with specified weight, it will encounter such inconvenience that no desired weight is known when the total price is specified and the corresponding weight is to be weighed out.
Accordingly, an object of this invention is to provide a price calculating balance having a function of immediately calculating and indicating the desired weight upon setting unit price and aimed price.
According to this invention, a price calculating balance is provided with means of encoding and storing a measured value of weight, means of storing a unit price, a multiplier for multiplying the contents of the price storing means and weight storing means and price indicating means for indicating the resultant product, as in the prior art price calculating balance. The price calculating balance is further provided with means of storing an aimed price, a divider for dividing the content of the aimed price storing means by the content of the unit price storing means and desired weight indicating means for indicating the result of division.
Now, the invention will be described in more detail with reference to the accompanying drawings and in conjunction with an embodiment thereof.
In the drawings:
Figure 1 is a block diagram representing an arithmetic circuit of a price calculating balance embodying this invention; and
Figure 2 is a pront view of a price calculating balance inciuding the circuit of Fig. 1, whichsshows an example of arrangement of its display pannel.
Throughout the drawings, corresponding portions are provided with same reference numerals.
Referring to Fig. 1, block 1 labelled "bal ance", which represents a weight measuring and encoding device, may be a device disclosed, for example, by U.S. Patent No.
3,612,842 or 4,146,873, which serves to sense movement of the weighing cradle in optical fashion and convert it into a binary digit representing the weight. The binary digit w representing the weight is stored in a weight register 2, the content of which is converted into a decimal number by a weight indicator 3 and indicated visually in a display window 3 on a front display panel of Fig. 2.
Block 4, representing a key board input device, includes an input key board 4 as attached to the front display panel as shown in
Fig. 2 and an encoder for converting a numerical value input thereby into a binary digit, and its output is stored in a unit price register 6 through one conact 5a of a switch 5 and, at the same time, converted into a decimal number by a unit price indicator 7 to be indicated in a display window 7 of Fig. 2. Output u of the unit price register 6 and output w of the weight register 2 are multiplied in a multiplier 8 and the resultant product is converted into a decimal number by a price indicator 9 and displayed in a display window 9 of Fig. 2.
Thus, the unit price, total weight and price of article are displayed respectively in the display windows 7, 3 and 9 of the display panel. The above-described is a known arrangement in the prior art price calculating balance.
By turning the switch 5, the key board input device 4 is coupled also through another contact 5b to an aimed price register 1 0. The switch 5 is arranged to be turned into its contacts 5a and 5b by pushing respectively push buttons 5a and 5b on the display panel of Fig. 2. When the push button 5b is pushed to input an aimed price through the key board 4, the aimed value is converted into a binary digit and stored in the register 10 and, then, converted into a decimal number by an aimed price indicator 11 and indicated in a display window 11 of Fig. 2.The output p of the aimed price register 10 is also coupled to a divider 1 2 with the output u of the unit price register 6.The divider 1 2 divides the output p by the output uto produce a binary output representing the desired weight, which is in turn converted into a decimal number by a desired weight indicator 1 3 and indicated in a display window 1 3 of Fig. 2. Accordingly, one may increase or decrease the article on the weighing cradle 1 so that the displayed value in the weight display window 3 coincides with the displayed value in the desired weight display window 1 3.
As described above, the price calculating balance of this invention displays the desired weight immediately upon setting the unit price and aimed price of article and, therefore, makes trade of article further convenient.
The above description has been made for illustrative purpose only and none of its details confines the invention. Various modifications can be made on the above embodiment within the scope of this invention as defined in the appended claims. For example, the structure of numerical input device and the arrangement of display devices can be designed arbitrarily by those skilled in the art. It is a matter of course that it is convenient to make adequate indications of units of weight and price and respective contents of display at the respective display windows, though not shown in the drawing.
Claims (3)
1. A price calculating balance, comprising means of measuring weight and encoding and storing the measured value, means of presetting and storing unit price, a multiplier for multiplying the contents of said unit price storing means and weight storing means, and price indicating means for indicating the result of said multiplication, wherein the balance further comprises means of presetting and storing aimed price, a divider for dividing the content of said aimed price storing means by the content of said unit price storing means, and desired weight indicating means for indicating the result of said division.
2. A price calculating balance, according to Claim 1, wherein said unit price storing means and aimed price storing means are coupled through a turn-over switch to a common numerical value input device.
3. A price calculating balance substantially as herein described with reference to the accompanying drawing.
