Abstract

PURPOSE:To prevent the activity efficiency of a main storage from being lowered by preparing the correspondence table of a format parameter with a document index, and conforming one format parameter to plural document indexes. CONSTITUTION:The title system is provided with an ID write control part 5 not operated when the ID number of a document desired to store and a format parameter pointer are already stored and which performs a write operation when non of them are written. Also it is provided with a load control part 4 which loads the format parameter on a second memory circuit 2 from an external storage 3 when receiving a load indication signal, and the external storage part 3 having the correspondence table representing the correspondent relation of multiple-to-one relation between a format ID and the format parameter, and the format parameter. Therefore, it is possible to register plural document IDs on a first memory circuit 1 by one time of loading, and also, the second memory circuit 2 consumes only an area of one format parameter. In such a way, the activity efficiency of the main storage can be heightened.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a format/P parameter loading method in an optical character reading device having a format parameter in an external storage device.

[Conventional technology]

Conventionally, this type of device requires a format parameter that defines the format of the form to be read, but since there are many types of format parameters, the total capacity of the i4 parameter is not as large as the main memory capacity. Load and use only the appropriate format parameters. At this time, load as many format parameters as possible within the capacity of the main memory, and only when you need a format parameter that is not in the main memory, load one of the formats in the main memory. Delete.

Load the required format 9 parameters into the empty space. The index (ID) number of the form is used to manage format parameters.

10 number and format) There is a one-to-one correspondence between iR parameters.

[Problem to be solved by the invention]

In the conventional device described above, there is a one-to-one correspondence between the ID number on the form and the format parameter.

If the ID numbers of the forms are different but the contents of the format and parameters are the same, that is, if there are multiple forms with the same format but different ID numbers, one of them has already been loaded. However, since the form has a different ID, it will be loaded again, consuming main memory.

As mentioned above, conventional devices have the disadvantage that unnecessary loads are performed and the utilization efficiency of the main memory is also reduced.

Therefore, the present invention aims to provide a format/parameter loading method that does not reduce the utilization efficiency of the main memory in an optical reading device having format/parameters in an external storage device.

[Failure to solve the problem]

The format parameter loading method of the present invention is as follows.

In order to achieve the above objective, a correspondence table between format parameters and form indexes is prepared in a format parameter loading method that loads format parameters necessary when reading forms with an optical character reader into the main memory. , one format/J parameter is made to correspond to a plurality of form indexes.

[Failure to solve the problem]

That is, according to the present invention, a first memory circuit stores a pointer to the rD number and format parameter of a document, a second memory circuit stores a pointer to the format parameter, and a pointer to the ID number and format of the read document. It has a function of writing the parameter pointer to the first storage circuit, and does not operate when the ID number and format parameter pointer of the form to be stored are already stored, and does not operate when the ID number and format parameter pointer of the form to be stored are not stored yet. and an ID write control unit which issues a load instruction signal at the same time.

a load control unit that loads format parameters from an external storage to a second storage circuit upon receiving the load instruction signal, and a many-to-one combination of form ID and format parameters;
A format and parameter loading system can be obtained that has a correspondence table that represents correspondence between relationships and an external storage section that has formats and meters.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing one embodiment of the present invention. In FIG. 1, 1 is a first memory circuit that stores a pointer to the form ID number and format parameter, 2 is a second memory circuit that stores the format number and parameter, and 3 is a 4 is an external storage unit that stores a correspondence table between a format parent parameter that defines the format, a form ID, and a format parameter, and 4 is a second storage circuit that stores the format of the external storage unit 3 upon receiving a load instruction signal. 2, and 5 is an ID write control unit that issues the load instruction signal when the ID number of the form read by the optical character reading device is not stored in the first storage circuit l. It is.

If the necessary form ID is not stored in the first storage circuit 1, the ID number is input to the ID writing control section 5,
The ID write control section 5 sends the ID number to the load control section 4 as a loading instruction.

The load control unit 4 searches for a corresponding format parameter from the ID number and loads it into the second storage circuit 2. Thereafter, the form ID corresponding to the corresponding format parameter is read from the correspondence table in the external storage section 3. A pointer indicating the position of the loaded format parameter on the second storage circuit 2 and the form ID read from the correspondence table are sent to the ID writing control section 5 as a response for completion of loading.

The ID writing control unit 5 receives the received pointer and form ID.
The first memory circuit 1 is updated. Multiple forms I in the correspondence table
If D is recorded, multiple areas of the first storage circuit 1 will point to one format parameter of the second storage circuit 2. As a result, a plurality of form IDs can be registered in the first memory circuit 1 with one load, and the second memory circuit 2 only consumes an area for one format/grammer.

〔Effect of the invention〕

As explained above, the two aspects of the present invention have the effect of avoiding loading of format parameters and increasing the utilization rate of the main memory when reading a different document with the same format parameters.
