Abstract

PURPOSE:To effectively utilize the sace of an ROM, by selecting a program and a code table by designating a control terminal, so that they can be used for keyboards of multifunction and many kinds. CONSTITUTION:This device is composed of a switch matrix 11, a keyboard encoder 12, a machine kind setting encoder 13 and a buffer 14. The keyboard encoder 12 has a control program, code tables I -VIII and a control terminal, and its control terminal is controlled by the encoder 13 connected to the outside. The code tables I -VIII correspond to different kinds of machines, respectively, and these code tables are selected by depressing machine kind designating switches A-H. In this regard, it is also possible to increase the number of code tables by increasing the capacity of an ROM of the encoder 12.

(2) Prior Art and Problems Figure 1 shows an example of a conventional key I-code encoder. The data is converted into a grammatical pull read-only memory 3 (hereinafter abbreviated as @FROM), and its output is outputted using a straw-ys'rm, then taken out from 7A4 and output as a code. In Figure 2, it is better to include the FROM shown in Figure 1 in the encoder 5 and to construct a dedicated mask each time.

The keys shown in Figures 1 and 2 above are all key 2-
The encoder had a single function and could only be used for special codes (such as those for J184 mode or IICCII mode), and could only convert codes for 91 models. For this purpose, it is necessary to use an I'ROM for code conversion as shown in Figure 1, or to construct an I-ROM each time for mass-produced products as shown in Figure 2, making the peripheral circuitry complicated. There are also drawbacks in terms of reliability.
