Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a pattern reading device, particularly when reading an item on which information such as a product name code, product name, unit price, quantity, amount, etc. is written on a form. The instructing information is controlled to serve as the stop position of the immediately preceding item, and the item is controlled to be read by the information instructing the start position and the item reading instruction information, thereby saving the storage area of control information regarding each item. The present invention relates to a pattern reading device configured to do this.

Generally, in a pattern reading device for a form or the like, pattern information on a form is divided into items such as product name code and unit price, and these items are read separately.

Conventionally, such pattern reading devices have been provided with start position information indicating the start position of the item to be read and stop position information indicating the stop position, and have been provided with start position information indicating the start position of the item to be read and stop position information indicating the stop position. Read pattern information.

Therefore, in conventionally known pattern reading devices, it is necessary to store start position information and stop position information for each item.

For example, if the length of the form is 30.48 (α) (12 inches) and the interval between one scanning line is 0.127 (of) (0.05 inches), the above start position information and stop position information 8 bits are required.

An object of the present invention is to reduce the storage area of a storage means for storing the start position information and stop position information.

Therefore, the pattern reading device of the present invention divides the reading storage area on the form into a plurality of items located in adjacent positions, and gives a reading instruction to each item to write to each item. A pattern reading device that reads the pattern information contained in the item is configured to perform control such that the start position of each item is regarded as the stop position of the immediately preceding item, and the start position of each item is specified for each item. A storage means is provided for storing start position information for scanning the item and reading instruction information for instructing whether or not to perform scanning on the item, and a storage means is provided for storing start position information for scanning the item and reading instruction information for instructing whether or not to perform reading for the item. Regarding reading, the present invention is characterized in that, based on the content of the reading instruction information, reading control is performed in response to reading instructions given for each item.

This will be explained below with reference to the drawings. FIG. 1 is an explanatory diagram for explaining the present invention in detail, and FIG. 2 shows the configuration of an embodiment of the present invention.

In FIG. 1, 1 is a form, 2-1 to 2-6 are items, 3-1 to 3-6 are husband start position information (or its storage part), which corresponds to each item, 4-1 to 4-6 are stop position information (or its storage part) corresponding to each item; 5;
-1 to 5-6 are read mode instruction information storage units, in which read control information such as information indicating the character font to be written on the item is stored, Ll and L2. ．． ...L6 represents the boundary position of each item.

Items 2-1 and 2 on form 1 are scanned by all reading devices.
-3, 2-4, and 2-5 only are read.

In this case, in the conventional device, start position information L1, stop position information L2, and reading control device (contents of read mode instruction information storage section 5-1) are prepared corresponding to item 2-1. -2, the start position information and stop position information are set to empty state, and the start position information, stop position information, and reading control information are prepared corresponding to items 2-3, 2-4, and 2-5, respectively. Then, corresponding to item 2-6, it is set to an empty state like item 2-2.

While the document 1 is scanned and read by the scanning section (FIG. 2), the scanning position is counted by the counter (FIG. 2).

When the content of the counter matches the information L1, reading starts from that time, and at the time 1 when the content of the counter matches the information L2, item 2-1 is read.
The contents are read as .

Then, from the time when the content of the color/li matches information L3 to time 1 when it matches information L4, from the time when it matches information L4 to time 1 when it matches information L5, and further from the time when it matches information L5 to information L6 At time point 1, which coincides with , are read respectively.

During this time, it is needless to say that the mode of reading is controlled by the reading control information 5-1 and 75-6.

However, in the case of the above-mentioned conventional device, information 3-1 to 3-6, information 4-1 to 4-6, and information 5 are provided for each item.
It is necessary to store -1 to 5-6 and press the button.

Especially when looking at the boundary between items 2-3 and 2-4 and the boundary between items 2-4 and 2-5 in the illustrated state, it is clear that the start position information of one item is the stop position information of the immediately preceding item. Even though they matched, it was necessary to store them separately.

The present invention improves the above points, and as shown in the lower part of FIG. In addition to serving as information, reading instruction information (information N) for instructing whether or not to read the contents of the item is provided in the read mode instruction information storage sections 5-1 to 5-6. .

That is, in the above examples, the read mode instruction information storage section 5-2 corresponding to item 2-2 and the read mode instruction information storage section 5-6 corresponding to item 2-6 are instructed not to read. Information (represented as N in the diagram)
Give them something to make them excited.

Then, the reading device regards the position from the position indicated by the information L1 to the next position 1 indicated by the information L2 as the first item, that is, the item 2-1, and determines whether or not to read the contents of the item. Determined by presence or absence.

For example, in the illustrated case, it is assumed that the contents of item 2-1 exist from the position given by information L1 to position 1 given by information L2, and the contents of item 2-1 are read.

For illustrated item 2-2, its contents range from the position given by information L2 to position 1 given by information L3.
It is assumed that it already exists, but reading is omitted.

FIG. 2 shows an embodiment of the present invention, in which reference numeral 6 is a form scanning section, 7 is a reading processing section, 8 is a preprocessing section, 9-0, 9
-1, 9-2, . . . are recognition units, 10 are reading control units, 11 are random access memories, 12
is a memory data register, 13 is a scanning position counter,
14 is a comparison circuit, 15 is an AND circuit, 16 is a signal bus,
17 represents a control bus, and 18 represents a read instruction signal line.

The random access memory 11 has address positions corresponding to items on the form, and each address position stores a pair of start position information and the contents of the read mode instruction information storage section. be made into

On the other hand, the scanning unit 6 supplies a clock signal to the scanning position counter 13 in accordance with the scanning position on the form.
Counted by 3.

The pattern signal on the form corresponding to the scan by the scan unit 6 that has been scanned is supplied to the preprocessing unit 8 and preprocessed, and then sent to the signal bus 1.
6 to each recognition unit 9-0, 9-1, 9-2, .
It is selectively supplied to ... as needed.

Then, pattern information on each item is recognized based on the recognition result by each recognition unit.

Assuming that you are now aware of the contents of item 2-1,
The start position information L2 and the contents of the read mode instruction information storage section 5-2 are read out from the memory 11 to the register 12.

In this state, when the contents of the counter 13 match the information L2 (ie, when the item 2-2 is entered), the comparison circuit 14 outputs a match output.

However, at this time, since information N is written in the contents of the read mode instruction information storage section 5-2, the AND circuit 15
The other input of is placed in the logic 10J, and the AND circuit 15 is not turned on.In other words, each recognition unit 9-0, 9-1.12°, . . . does not need to read the item 2-2. is instructed.

At this time, the item 2 is sent to each recognition unit via the bus 17.
The transition from -1 to 2-2 is notified, and corresponding control is performed.

Next, information L3 and the contents of the read mode instruction information storage section 5-3 are read out from the memory 11 to the register 12, but when the contents of the counter 13 match the information L3, the comparison circuit 14 emits matching output.

At this time, the information N is not written in the contents of the read mode instruction information storage section 5-3, and the AND circuit 15 is turned on.

Each recognition unit 9-0.9-1.9-2. ... is notified by bus 17 that it has entered item 2-3, and knows by signal line 18 that it is the item to be read.

The same applies to items 2-4 and 2-5, and it is notified that item 2-6 does not need to be read.

As explained above, according to the present invention, as shown in the bottom row of FIG. The system determines whether the contents of each item should be read or not.

Therefore, the storage capacity of the storage means 11 may be small, or it can be used for storing other more important information.

Furthermore, by using a random access memory as the storage means 11 as shown in FIG. 2, the start position information and the like can be freely rewritten according to the items of various forms.
