Abstract

PURPOSE:To read out rapidly continuous character strings and to output the character strings on a printer or a display device by providing the titled device with a storage device, multi-head type disc device, and an output line buffer, etc. CONSTITUTION:A conversion table 1 in the generator for character signals or the like stores or decodes a track and a selector number corresponding to a character code signal A. The track and selector number string B from the table 1 are supplied to a storage device 2 and an appearance order number and a storage bit are added. A track and a selector number string C stored in the device 2 are read out and stored in a storage device 3. A track order track and a selector number string D read out from the device 3 are used to access a moving head type disc device 4 and a character signal E is outputted. An appearance order number signal G from the device 3 is applied to an output line buffer 5 and written in the buffer 5 on the basis of the signal E from the device 4. After inputting a character string of one line, the buffer 5 transmits a character signal F to an output device 6 to read out continuous character strings rapidly.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a character signal generation device, mainly used in a kanji processing device or the like.

[Background technology]

When a moving head type disk device is used as a storage device for character signals, etc. (1) Because of magnetic storage, there is no need to write characters, etc. each time the power is turned on, so time can be saved.

(2) It is easy to rewrite characters, etc.

(3) The cost per bit is low.

Because of these advantages, it has often been used as a storage device for character signals, etc.

However, the access time of a moving head type disk device is generally expressed as the average head seek time + average seven-digit search time, but the head seek time occupies a larger amount of time than the sector search time, and the i seek time is Depends on head position. For example, the time it takes to move to the next truck is t-Oms & the time it takes to move to the farthest truck is 100m5. average 50m
It is 5.

Therefore, when a moving head type disk device is used as a character signal generation device, the access time for character signals, etc. is nXT, where the number of characters is n and the average seek time is T, and the time required to read characters, etc. is nXT. This occupies a large amount of the processing time of kanji processing devices that use character signal generators.

[Purpose of the invention]

Therefore, the present invention provides a character signal generating device that uses a moving head type disk device, such as a floppy disk device, as a character signal storage device, which reads continuous character strings at high speed and outputs them to a printing device or display device. This is what we are trying to provide.

[Narration of invention]

The present invention is a character signal generating device that stores data such as characters, 6 turns, etc. in a moving head type disk device and reads out data corresponding to a given character code. , First, a conversion table for outputting the track and sector numbers in which each character etc. are stored, and a storage device ah for storing the track and sector numbers, and numbers indicating the appearance order of the characters etc. corresponding to those track and sector numbers are added, A storage device that stores a table sorted by track numbers.

There is a moving head type disk device that reads out character patterns etc. as track numbers, and the order in which the characters etc. appear.

[Embodiments of the invention]

FIG. 1 is a block diagram of an embodiment of the present invention, in which reference numeral 1 denotes a conversion table consisting of a storage device or conversion device for storing or decoding track and sector numbers corresponding to character code signals.

When an external character code signal string is given to this conversion table 1, a track 1 sector number string B corresponding to the character code signal string is output from the conversion table 1.
For example, as shown in FIG. 2, the data are sequentially stored in the storage device 2.

Reference numeral 8 denotes a storage device, and this storage device has a track face track sector table (hereinafter referred to as a track order table) in which the tracks are arranged in descending order of the total number of tracks m on the disk as one table, and a one-character code output. fA order,
That is, the track sector number string 0 read out from the storage device 2 in character string order is stored in the track order table corresponding to that track number.

In this case, a face number (appearance) is assigned in the order of appearance of the track number 0 column 0, and this is also stored in the track order table corresponding to the track number.

In this way, the track sector number sequence υ is stored in the track order table in order of track order, and when a character code of the same track number appears, it is stored in the next track order table.

Furthermore, for example, by adding n to the stored bit when storing in the trunk order table, when reading out the storage device R3, when reading one bit, if it is 's1#, the disk is accessed, and if it is 1%0#, it is skipped. If you do this, you can easily determine whether or not there is a disk access.

FIG. 4 is an explanatory diagram showing a disk access method. In the moving head type disk device 4, all tracks on the disk correspond to the track order table, and the track order table read from the storage device 3 is shown in FIG. The disk is accessed by sector number sequence, and a character signal E is output.

On the other hand, at the same time as the readout of the track order track sector numbers, the appearance order number signal G of characters etc. is output, and the character signal B is placed at the position of the output line packer 5 given by the appearance order number 9 signal G. It is written as shown in Figure 5. After one character string is input to the output 2 input buffer 5 in this way, the character signal F is transmitted to the output device 6.
sent to.

As can be seen from the above description, in the present invention, the time required to read out character signals, etc. is significantly reduced compared to the conventional method, and it takes time t.
Since characters, symbols, etc. are rearranged and read out in the order of the track number, the moving head only needs to be moved in order.
Read time is significantly reduced.

Furthermore, even when reading out characters such as external characters that are not resident in a character signal generating device such as a kanji processing device from an external moving head type disk device, it is possible to significantly reduce time by using this method. This is an excellent device for generating character signals in practical use.

It goes without saying that the present invention can be applied to a disk pack device having several heads, that is, a cylinder type disk pack device.
