Memory device in the phone

1 is a diagram for explaining a memory device of a conventional telephone.

2 is a diagram for explaining a memory device of a telephone according to the present invention;

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a memory device of a telephone, and more particularly, to a memory device of a telephone that allows a predetermined information to be recorded in a memory device of a telephone through an input device such as a keypad during a call.

In general, a telephone is a communication device that converts an acoustic signal into an electrical signal or converts an electrical signal into an acoustic signal to exchange information. Currently, various additional functions are added to help a user's convenience.

As a representative example, the speed dialing function automatically stores a telephone number stored in a memory device by inputting a specific phone number into a memory device, and later retrieves a phone number stored in the memory device using a speed dial button. will be. To do this, it is necessary to input a desired telephone number into the memory device in advance.

1 is a view for explaining a memory device of a conventional telephone.

The input section consists of a keypad and function buttons of the telephone. The keypad is organized around the numeric keys to enter the telephone number. Function buttons are buttons for the user to control each function of the phone, and a plurality of function buttons are provided according to the number of functions added to the phone.

The signal generated at the input unit is transmitted to the controller through the switch (S). The controller controls the overall operation of the phone, and stores the signal generated from the function button of the input unit and the signal generated from the keypad in the memory unit or outputted to the display unit.

A process of performing a speed dial function in a memory device of a conventional telephone configured as described above is as follows.

First, press the memory button or the shortcut button among the function buttons to memorize the phone number, and then enter the phone number to be stored through the keypad. Press the memory button or shortcut button again, and then enter one of the numbers from 0 to 9 and assign the shortcut number to the stored phone number.

Next, to make a call using the speed dial function, press a memory button or a speed button in the standby state of the phone, and then select and input a desired speed number. The controller fetches the telephone number corresponding to the input shortcut number from the memory unit and outputs the signal to the corresponding telephone number while simultaneously outputting the telephone number to the display unit composed of a liquid crystal display.

When the dialed number and the call are established, the switch S of FIG. 1 is turned off to block the signal transmission path between the input unit and the controller.

That is, in the conventional telephone, the telephone number can be input into the memory only in the standby state, and the signal generated from the input unit is not transmitted to the controller during the call. If there is a need to store a new phone number in the memory device during a call, there is a problem in that the phone number input process must be performed after the call is completed separately.

Accordingly, the present invention provides a memory device of a telephone which stores a telephone number in a memory unit in a standby state as well as during a call and sequentially displays the telephone number on a liquid crystal display, so that a separate telephone number is not required even during a call. The purpose is.

The present invention for this purpose is a telephone including a handset for converting acoustic energy into electrical energy, a handset for converting electrical energy into acoustic energy, a memory unit capable of writing and reading, and a display unit for displaying the operating state of the telephone. The memory device includes an input unit and a frequency / voltage converter, control logic, and a controller.

The input unit includes a function button for controlling a shortcut function or a recording function, and a keypad for receiving a telephone number or a setting number and generating a predetermined signal. The frequency / voltage converter generates an enable signal by converting an audio signal and a frequency input / output through a handset into a voltage signal while a call is established. The control logic is enabled by the enable signal, and receives and transmits a signal generated from the input unit. The controller receives a signal from the control logic, stores it in the memory unit, and transmits the signal to the display unit.

Referring to FIG. 2, a preferred embodiment of the present invention made as described above is as follows. 2 is a view for explaining a memory device of the telephone according to the present invention.

The input section consists of a keypad and function buttons of the telephone. The keypad is organized around the numeric keys to enter the telephone number. Function buttons are buttons for the user to control each function of the phone, and a plurality of function buttons are provided according to the number of functions added to the phone.

The signal generated at the input unit is transmitted to the controller through the switch S '. The controller controls the overall operation of the telephone. The controller stores signals generated from the function buttons of the input unit and signals generated from the keypad in the memory unit or outputs them to the display unit.

In addition, the signal generated at the input unit is input to the control logic. When control logic is enabled, a signal from the input is sent to the controller. This control logic is enabled by control signals generated by the frequency / voltage converter. The frequency / voltage converter receives an audio signal input and output from a telephone, and converts a frequency signal of the acoustic signal into a voltage signal.

The voltage signal generated by this frequency / voltage converter is used as a control signal to enable the control logic. In other words, by converting the frequency signal of the acoustic signal into a voltage signal to enable the control logic to enable signal transmission between the input unit and the controller during the call.

The speed dial function in the present invention configured as described above is performed as follows.

When the user dials a predetermined telephone number and the call is established, the switch S 'is turned off to block the signal transmission path between the input unit and the controller. However, when a call is established and a conversation is received, the handset generates and outputs an audio signal, and the frequency / voltage converter converts the acoustic signal into a voltage signal to generate an enable signal.

The enable signal generated by the frequency / voltage converter enables the control logic to enable signal transfer between the input and the controller.

In this state, when the user needs to obtain a new telephone number and store it in the memory unit of the telephone, the user immediately presses a shortcut button and inputs the telephone number to be stored. The phone number entered is passed to the controller through the control logic. The controller stores the received phone number in the memory unit and delivers it to the display unit.

The memory unit continues to store the received telephone number until the user performs a separate operation even after the call is terminated, and the display unit also outputs the received telephone number so that the user can check it even after the call is terminated.

As described above, the memory device of the telephone according to the present invention provides a memory device of the telephone which stores the telephone number in the memory in the standby state as well as during the call and sequentially displays the telephone number on the liquid crystal display, thereby providing a separate memory device even during a call. This has the effect of eliminating the need to record phone numbers.
