Computer terminal device for producing different types of buzzer sounds

DETAILED DESCRIPTION It is an object of the present invention to provide a computer terminal device such as a printer or a CRT, wherein different buzzer sounds can be generated in accordance with corresponding types of input data, so that the operator can discriminate a specific reason he was called each time a buzzer sound is generated.
It is another object of the present invention to provide a computer terminal device such as a printer or a CRT wherein a buzzer sound is generated in one-to-one correspondence with input data representing a character.
According to the present invention, there is provided a computer terminal device for generating different types of buzzer sounds, said computer terminal device comprising buzzer sound data memory for storing a plurality of buzzer sound data which are obtained by converting different types of intermittent buzzer sounds to numeric values, each buzzer sound data representing a corresponding one of the different types of intermittent buzzer sounds.
The computer terminal device comprises a receiver for receiving coded data from the host apparatus, a data discriminator means for decoding the coded data received by the receiver, and an index register for storing data representing a decoding result of the data discriminator means.
The computer terminal device further has a buzzer sound readout and a buzzer unit.
The readout reads out the buzzer tone data corresponding to the data representing the decoding result from the buzzer sound data memory in response to an instruction supplied from the host apparatus.
The intermittent buzzer sound corresponding to the readout buzzer sound data is produced by the buzzer unit.
The above and other objects, features and advantages of the present invention will be apparent from the following detailed description taken in conjunction with the accompanying drawings.
