Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a display device for a vending machine that is effective for displaying product setting guidance, such as an amount display device for an account button in a ticket vending machine.

Conventionally, for example, in a ticket vending machine, etc., FIG.

(b) As shown in K, an account button (2) consisting of a plurality of 7-segment numeric displays (1) arranged on one operation panel (not shown)
; are arranged horizontally at regular intervals to display the amount. However, the numeric display (1) of the above account button (2)
)...... Money slot (not shown) K provided on the operation panel (For example, nothing will be displayed until a coin is inserted (see Figure 1 1)), and insert the coin. In particular, the account button (2) up to the input amount, the numeric display for K (1)...
...is lit up. (Figure 1 (
(See b)) This ticket vending machine has a built-in amount label for the account in the row button (2), and when you insert a coin, the round button (2) lights up and displays the amount up to that amount. You can purchase a train ticket by pressing the desired account button (2) from among the available account buttons. However, conventional ticket vending machines have the drawback of not knowing which account button to press unless coins are inserted, which can be very inconvenient for customers and can make them feel uneasy.

The present invention was made in view of the above circumstances, and its purpose is to display all the information displays of products sold under normal conditions in a brightness that customers can recognize, and to make it easier for customers to insert coins. ) By displaying the display with high brightness to guide the products that can be purchased with the input amount and distinguishing it from other displays, it is possible to determine which product selection key should be set for the purpose and to avoid inconvenience to the customer. The purpose of this invention is to provide a display device for a vending machine.

The present invention will be described below based on an embodiment shown in FIGS. 2-2(b) and 3. Conventionally, lighting methods for a 7-segment numeric display include a dynamic display method and a stacked display method, but in this embodiment, the dynamic display method will be used for explanation. Figure 3 is a block diagram showing the circuit configuration of this device. In the figure, the first clock pulse oscillator (11) sends pulses at a fast rate, and the second clock pulse oscillator (12) sends pulses at a slow rate. shall be. The first and second clock pulse oscillators (11)
, (12) K are connected to registers (13) and nine AND circuits (14), (Is) and OR circuits (16), respectively.
) to recall data, input color and digit specification via (
17) K connected. A storage device (1s) for storing input data is connected to the 0 output terminal of this counter (17), and a dotsipa (19) for converting the output terminal Ka mainary code V into 7 segments is connected to the output terminal of this storage device (18).
through the 7-segment numeric display (2G-1),
(20-2), (20-5)--K are connected to each other. A digit driver (21) is connected in parallel between the output end of the counter (17) and the output end of each numeric display (20), and is configured to drive the digit display. In addition, io Mori number display (20)
When the normal condition is 1IKTo, the numeric display (20
) is displayed, and when money is inserted into the input slot, this is an input signal that specifies and displays the number display (2o) with high brightness.

In order to close such a configuration, the first clock pulse is generated 111.
) (11) and a second clock pulse oscillator (12)
The pulses emitted from the first click pulse oscillator (11) call out the data stored in the storage device (III) via the counter (17). ) Number display II (20) is displayed at low brightness in order to send K. Therefore, when a coin is inserted into the money slot and displayed at high brightness, the input signal that specifies high brightness is input to the register (13) K when the coin is inserted, so the second clock/zooscillator ( In order to send the slow echo speed emitted by 12) to the numeric display (20), the numeric display (20), together with the digit driver (21), displays it with high brightness. The numeric display (20) C) can be displayed brightly.

As explained above, according to the present invention, under normal conditions, all the display devices for guiding sales products are displayed in a brightness that can be recognized by customers, and when a customer inserts a coin, the amount of money that can be purchased with the amount of money inserted is displayed. The product information display is brightly displayed with high brightness so that it can be distinguished from other displays, allowing customers to know the products on sale even before inserting coins, and making it easier to select the items they need to set. The position of the key can be determined by the display, and when currency is inserted, an indicator of products that can be purchased with the input currency can also be displayed.

Therefore, I feel uneasy about traditional vending machines.
By using the vending machine of the present invention, customers who have used the vending machine of the present invention will have less anxiety about operating it, and it will be possible to operate the vending machine in the same way as before. be.

[Brief explanation of the drawings] Figure 1-1(b) shows the account button in a conventional amount display device, (■) shows the non-displayed state before inserting money, and (b) shows the account button in the conventional amount display device. FIG. 2-9(b), a diagram showing the display state after money is inserted, shows the embodiment of the present invention. Money I [account button - on the display device] is displayed with low brightness before money is inserted. A diagram showing the state, (b) is a diagram showing a good state with high brightness after money is inserted, and SWA is a four-tree diagram showing the @ path configuration of the device. 20-1.20-4.20-5-One digit display 1B.

Claims (1)

[Claims] When a coin is inserted, the display corresponding to the input amount is turned on and the first clock pulse oscillator and the second clock pulse oscillator emit different pulses. A register connected to the second clock pulse oscillator and set to input a prescribed charge, and in a normal state when no coins are inserted, a display for guiding all products to be sold is connected to the first clock pulse oscillator. When coins are inserted, a display indicating products that can be purchased with the inserted amount is displayed at high brightness according to the pulses emitted by the second clock pulse oscillator. A display device for a vending machine characterized by displaying.
