Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vending type setting device for an automatic ticket vending machine, which allows the vending type to be easily set and reset.

Conventional automatic ticket vending machines are equipped with a printing mechanism that forms words to be printed on the surface of the ticket to be issued, and when the ticket is issued, one drive of the printing mechanism corresponding to the selected product prints the product name on the ticket. are doing.

However, such a device requires a printing mechanism depending on the type of part, and the type of part (i.e. menu), such as a ticket vending machine, is required.
If there are many numbers, the device becomes large and the control becomes complicated.

Furthermore, changing the product requires changing the printing mechanism, which is not very practical in terms of versatility.

Also, an automatic ticket vending machine that uses a printer capable of printing many types of characters, stores data indicating the characters to be printed in a semiconductor memory, reads the necessary data from the memory at the time of ticket issuance, and selectively prints the characters with the printer. is also put into practical use.

In such devices, the storage area of the memory is fixed depending on the part type, so necessary information (i.e., selling price, etc.) for each product must be set in a predetermined order. However, the operation is extremely troublesome.

In view of the above points, the present invention provides an apparatus in which a plurality of storage areas of a memory can be set to any part type by a setter.

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

FIG. 1 is a block diagram showing the authority of the automatic ticket vending machine according to the present invention, in which CPU 2 is a central control unit that controls the operation of the automatic ticket vending machine, 3 is an interface;
ROM 4 is a read-only memory, RAM 1 is a random access memory, 5 is an address decoder, 6 is an address bus, 7 is a data bus, and 8 is a terminal section.

The terminal section 8 is a general term for input/output devices in the automatic ticket vending machine, such as a currency accepting device 9, a product selection device 10, a printer 11 serving as a ticket issuing device, and a key device 12, and is connected to the CPU 2 via the interface 3.

In the figure, G indicates a gate circuit that controls the flow of data, and the chip select signal C81 generated from the address decoder 5.
It opens and closes in response to C82C83.

Necessary control procedures related to all operations of the automatic ticket vending machine are programmed in the ROM 4, and when the CPU 2 receives an input signal from the terminal unit 8, it specifies a predetermined address according to the contents and executes a given control procedure. Read from ROM4 and execute,
It is configured to output the calculation result or a predetermined control signal to the terminal section 8 via the interface 3.

When the CPU 2 stores data or calculation results input from the terminal, it specifies a predetermined address set in the control procedure and stores these data in the RAM 1.

In addition, ROM4゜R is used for address assignment by CPU2.
In addition to AM1, a key device 12 is also included, and the CPU 2 can read data from the key device 12 by setting a predetermined address when operating the key device 12.

The key device 12 is a figure key (start key), a pause key (memory section setting key), a l'U key (sales price setting key), -1
key (ticketing number setting key), same key (end key), moan)
It is composed of numeric keys from ``to decoy'' and letter keys from ``cause'' to ``figure.'' Operation of the figure key generates a start signal sta, making it possible to send and receive signals between the key device 12 and the CPU 2.

When a pause key, numeric key, or character key is operated, a strobe signal st is input to the CPU 2 via the interface 3, and ASCII code data generated by the operation of these keys is introduced to the CPU 2 via the data bus 7.

FIG. 2 shows the signal generating section of the key device 12, and shows the switch 1
3 outputs a sta signal when operated corresponding to the (8) key, and the keyboard matrix 14 corresponds to the group key, Shikoku key, and II.
It corresponds to the I key, interval key, character key, and number key, and the X of the encoder 15 is activated by operating these keys.

...X7 row and Y. . . . High level or low level signals are input to the y to column input terminals, respectively.

Figure 3 is a diagram showing the signal state input to the input terminal of the encoder 15 when each key is operated.
When the key is operated, input terminal

A high level signal is input to Y3.

When the encoder 15 detects the operated key, the encoder 15 converts the contents into a 2-digit binary code of 4 bits as shown in FIG.
” and “B1...B8” output terminals.

In the same figure, for example, 4 bits B1...B8 indicate "0".
・0, 1, 1'' and B, ...B4 4 bits make ``
When 0, 0, 0, 1 is output (that is, 31 in decimal notation), it indicates that the numeric key key i was operated.

In addition, when the ID-1 character key or number key is operated, the encoder 15 outputs the strobe signal st from the terminal [phase], and when the chip select signal C81 from the CPU 2 is input from the terminal 0, the gate circuit 16 is opened. Data in ASCII code is output from output terminals ■ to ■.

As shown in FIG. 5, the RAM 1 is provided with individual data storage sections M12M2, . . . corresponding to issued ticket types, and the individual data storage sections M12M2, . be able to.

In addition, the individual data storage units M12M2... each have an area of 10 bytes to store the name of the product being sold.
One character per byte can store up to 10 characters.

The operation according to the above configuration is as follows: First, when a start signal sta is input from the key device 12 to the CPU 2 via the interface 3, the CPU 2 specifies a predetermined address and reads out a control procedure related to data loading from the key device 12 programmed in the ROM 4. .

At this time, the address decoder 5 is set to output the chip select signal C81 in all address areas related to this control procedure, and data in the ASCII code generated from the key device 12 can be inputted to the CPU 2 via the gate circuit 16.

(8) After the key operation, the CPU 2 is in standby mode for the strobe signal st, and when the strobe signal is input via the interface 3 by operating the figure keys, the CPU 2 changes from B1 to B8 in ASCII code by operating the keys for the same time. The data generated at the output terminals up to “0・0−O−Ojl−0・0・
1.1".

When this data is input, the CPU 2 stores individual data storage units M1, M2, and M2 corresponding to the number of the next numeric key to be operated.
In order to select..., the mode returns to strobe signal standby mode.

When a numeric key is operated and a strobe signal and an ASCII code indicating a number are input to the CPU 2, the address of the individual data storage unit corresponding to this numeric number is specified in the RAM 1.

For example, when the ■ key is operated, the data "O-0.1.
1""0.0.0.1" is input to the CPU 2 and a predetermined address is written to the RAM 1 so that the individual data storage section M1 appears.
Specify to enter strobe signal standby mode.

Then, when you sequentially operate the character keys that make up the product name you want to set, a strobe signal and ASCII code data indicating the operated character are input to the CPU 2 and stored in the RAM.
Data is written to the address 1 in increments of 1.

For example, regarding the individual data storage unit M1 shown in FIG. J
(D7 in decimal), the ASCII code for the character “n” “
1.1.0.1” “1.1.O.IJ” (DD in decimal)
, ASCII code "1, 1, 0, 0J" indicating the character "chi"
I-0-0.0.1" (CI in decimal notation) are written for each byte.

Therefore, after selecting the individual data storage section M12M2, . . . and writing an arbitrary product name in ASCII code by operating the character keys, the individual data storage section can be made a dedicated storage section for that product type.

The individual data storage units M, , M2... have a 10-byte area for storing the product name as mentioned above, but they also have an area for storing sales prices, ticketing numbers, etc. ) or the side key (ticketing number setting key), the CPU 2 receives the strobe signal st and the fourth
The data in the ASCII code shown in the figure "0, 0, 0, 0
” “0.1.0.1” (05 in decimal) or “0.0
・0・O” “1・1・1・0” (OB in decimal) is CP
Input to U2, the CPU 2 specifies the address where the selling price or ticket issue number is to be stored.

When a numeric key indicating a selling price or a ticket issue number is operated, a strobe signal st and data in an ASCII code indicating a numeric value are generated, and this data is written into a designated storage area.

Then, after setting the product name and sales price ticket number related to the product, when the M key and number keys are operated, the CPU 2 newly specifies the individual data storage unit corresponding to this number, writes the next product name, and selects the product. This is a dedicated storage section.

In this way, when the individual data storage units M02M2, . O” “1・1・0・I J
(OD in decimal) is introduced into the CPU 2, confirms completion of data setting, and reads and executes other control-related programs from the ROM 4.

To explain the ticket issuing operation, after a predetermined amount is inserted, the product selection device 10 is operated by the customer and the selection signal is
When introduced into the PU 2, control procedures related to ticket issuing operations are read from the ROM 4.

The selection switches IOA...Ion correspond to the individual data storage units M12M2..., respectively, and the CPU 2 selects the individual data storage units M1 according to the input selection signals S1...Sn.
In order to select 2M2..., a predetermined address is specified in RAMI.

Then, the CPU 2 reads the sales product name, sales price, and ticket issue number to be printed on the ticket from the selected individual data storage section, converts this ASCII code data into data that can be printed, and sends the interface 3 to the printer 11. Output via

At this time, the procedure for converting the ASCII code into data for printing is set in ROM4, and the CPU
2 executes data conversion.

In the embodiment, the storage section is selected by operating both the storage section setting key and the numeric keys, but the two are made common and the first storage section setting key and the first It is also possible to provide two storage section setting keys.

According to the present invention described in detail above, an individual data storage section that is provided with an individual data storage section corresponding to a sales product type and that is arbitrarily called up by a key device can be made into a dedicated storage section for an arbitrary product type using the same key device. This has the effect of facilitating the setting operation.

Moreover, since the type name can be set by key operation by the administrator of the ticket vending machine, it is possible to realize a highly versatile ticket vending machine that can correspond to all the menu names of the cafeteria in which it is used, and it is also possible to reset the settings.
