Description

TECHNICAL FIELD The present invention relates to a liquid supply device including an electronic display device.

(Prior Art) With the practical use of microcomputers, it becomes possible to easily perform various types of information processing. In addition to displaying the amount of liquid to be supplied, the liquid supply device can also display the metal and unit price. Has started to take place.

Conventionally, such various data displays have been performed by providing a plurality of display devices and outputting corresponding data to the individual display devices, but the area occupied by the display panel is not only increased. However, depending on the type of customer, even unnecessary information is displayed, which causes confusion.

(Object) In view of such a problem, the present invention includes an electronic display device capable of selectively displaying various information on the same display panel and accurately recognizing the meaning of displayed data. It is an object to provide a liquid supply device.

(Structure) Therefore, details of the present invention will be described below based on illustrated embodiments.

FIG. 1 shows an embodiment of the present invention. In the figure, reference numeral 1 is a control unit which is a characteristic part of the present invention. As shown in FIG. Counting means 1a for accumulating flow rate signals and unit price storage means 1b for storing unit price data from a key board 4 provided in the liquid supply device body 3
And an amount calculation means 1c for obtaining a sales amount based on the data from both means 1a and 1b, and a switching means 1e for selectively outputting the data from these means 1a to 1c to the drive means 1d.
And a display content changeover switch provided on the liquid supply device body 3.
The display control gate 1f for controlling the switching means 1e by the signal from 12 and the motor 5 by the signal from the nozzle switch 6
It is composed of a motor control means 1g for turning on and off.

Returning to FIG. 1 again, reference numeral 7 in the drawing is a pump driven by a motor 5 for pumping fuel oil from an oil storage tank (not shown) to a nozzle 9 via a flow meter 8.
Reference numeral 10 denotes a dot-matrix type display panel mounted with the display surface exposed to the outer surface of the liquid supply device main body 3, which displays data from the control device 1. As shown in FIG. Units [YEN / LITER] 11a, [LITER] 11b, and [YE] according to the display position of the numerical data output to
N] 11c is provided with the unit display section 11, and data that should be displayed regardless of which of the important data in the transaction is displayed, that is, [LITER] 11b indicating the unit of the liquid supply amount is arranged in the center, Moreover, it is marked with emphasized characters so that it is more conspicuous than other units.

Incidentally, reference numeral 13 in the figure denotes a nozzle hook attached to the main body of the liquid supply device.

Next, the operation of the apparatus configured as described above will be described based on the flowchart shown in FIG.

Prior to the start of business, the unit price of the fuel oil to be sold on the day, 173 yen, is entered from the key board 4 and the unit price storage means 1b
To store. When the customer is a customer who does not need to display the amount of money, the display non-display switch 12 selects the amount non-display mode when the nozzle 9 is set in the nozzle hook 13. Thereby, the switching means 1e,
It is set so that only the count value of the counting means 1a is output to the drive means 1d.

When the nozzle 9 is removed from the nozzle hook 13 at the stage where such preparation is completed, the nozzle off signal is input from the nozzle switch 6 to the control device 1. Receiving this signal, the counting means 1a and the amount calculation means 1c of the control device 1 reduce the previous count value to zero and set the value "0" of the count means 1a to the central portion of the display panel 10,
That is, the liquid supply amount unit [LITER] 11b is displayed in a large size corresponding to the marked position. And the motor control means 1g
The motor rotates by the output of 1 to operate the pump 7 to start liquid supply, and a pulse signal is output from the pulse transmitter 2 provided in the flowmeter 8. The counting means 1a integrates the pulse signals and converts the counting content into a liquid supply amount and displays it on the display panel 10 in a large size (I in FIG. 5). At this time, in the lower part of the display panel 10 displaying the liquid supply data, “LITER” is marked more clearly than other units in white in black, so even if it is now displayed on both sides. [LITER / YEN] 11a and [YEN] 11c that have nothing to do with existing data
Even if is present, the customer knows that the numerical value displayed on the display panel 10 is the liquid supply amount. After the liquid supply is completed, set the nozzle 9 to the nozzle hook and set the nozzle switch 6
When turns off, the motor 5 stops.

When the next customer is a customer of a cash transaction that needs to display the amount of money, with the nozzle 9 set to the nozzle hook 13, the display changeover switch 12 is operated to select the amount display mode. To do. As a result, the switching means 1e can output the numerical values of the counting means 1a, the amount calculation means 1c, and the unit price storage means 1b to the drive means 1d.

In such a state, when the nozzle 9 is removed from the nozzle hook, the numerical value "173" is displayed on the left end side of the display panel 10 after the count values of the counting means 1a and the amount calculation means 1c are zeroed. The customer knows that the data currently displayed is a unit price of 1 liter because there is a marking of "YEN / LITER" 11a at the bottom of this value. When the liquid supply is started in such a state, the motor 5 rotates to supply the liquid, and the flow rate signal from the pulse transmitter 2 is counted by the counting means 1a. At the same time, the amount calculation means 1c calculates the sales amount based on the liquid supply amount of the counting means 1a and the unit price stored in the unit price storage means 1b, and then displays the unit price, the liquid supply amount, and the amount of money in this order. Place a space in the space to display in a horizontal row (Fig. 5 II).

By the way, at the bottom of the display panel 10, "YEN / LITER" 11a, "LITER" 11b, "YE
Because "N" 11c is marked, I bought 59.24 liters of fuel oil for 173 yen per liter, resulting in a price of 10.248.
The customer instantly recognizes that it has become a circle. In this mode, since the number of characters to be displayed on the display panel is large, the display font is a compressed and relatively small font.

In the above-described embodiment, the important unit is marked on the black background with a white outline so as to be conspicuous, but characters larger than other units may be used or a blinking light may be provided. Needless to say. Further, in this embodiment, the display content changeover switch 12 is provided independently, but it can also be used as one switch in the keyboard.

(Effect) As described above, according to the present invention, it is possible to arbitrarily display only the liquid supply amount or display the unit price, the liquid supply amount, and the amount of money on one display panel. Only the information can be displayed, and the unit is marked according to the display position of each data, so multiple data generated by liquid supply operation can be displayed in a single display without increasing the display area. Not only can it be displayed on the means, but the meaning of the displayed numerical value can be immediately judged, and troubles can be prevented.
