Abstract

PURPOSE:To improve the operability even at the time of the multifunctional use of dial keys by illuminating only numerals at the time of using dial keys for numerical operation and illuminating only modes at the time of using them for modes. CONSTITUTION:When one of autodials (A-1) to (A-3) is operated, a light emitting device 4 is extinguished to stop the illumination of display 2b of autodials (A-1) to (A-3) and the display 2c of abbreviation. Simultaneously, a control circuit 9 inputs the output, which flickers a light emitting device 3, to an illuminating circuit 10 to illuminate the display of numerals and symbols by flickering. When a register key 6 is not operated, the circuit 9 monitors whether a dial key 2 is operated or not. When a telephone number is registered and it is detected that the key 6 is operated, the circuit 9 sends the numerals of the registered telephone number by a speech recognizing circuit to terminate the registration of autodials.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone set in which the dial key can be used for other purposes, such as operation keys such as abbreviated number keys or auto dial keys.

[Conventional technology]

Traditional telephone dial keys (Punsche type) are
You can use it to manipulate the phone number of the person you are calling, or just use it to store abbreviated numbers in the phone's built-in memory, or to store auto-dial settings. There was only one. Here, abbreviation refers to reading out a telephone number by operating both the abbreviation key and the dial key, which are provided separately from the dial key, and auto dialing refers to reading out a telephone number by operating both the abbreviated operation key and the dial key, which are provided separately from the dial key. By operating one of a plurality of separately provided auto-dial keys, the telephone number corresponding to that key is read out.

[Problem to be solved by the invention]

By the way, the dial keys in the conventional telephones mentioned above only serve as numeric operations, and when dialing a telephone number by speed dialing or auto dialing, you must operate other operation keys other than the dial keys. Must be. That is, these operation keys must be placed on the telephone separately from the dial keys, which poses problems such as hindering the miniaturization of the telephone and increasing the number of parts, resulting in higher costs.

[Purpose of the invention]

The present invention aims to solve the above-mentioned problems, and its purpose is to reduce the size and cost of telephones by making dial keys usable for numeric operations and other operations. Moreover, when used for numerical operations, only the numbers are illuminated, and when used for other operations, the characters representing other operations are illuminated. To provide a telephone with good operability even when dial keys are used for multiple functions.

[Summary of the invention]

The present invention aims to achieve the above-mentioned object, and its gist is to form a display indicating normal dial characters and other operation modes on a dial key, and to provide two light emitting lights on the back side of the dial key. When the dial key is used for numeric operation, one of the two light emitters is lit to illuminate only the numbers, and when the dial key is used for other modes, the other light emitter is lit. It is designed so that only the mode is illuminated.

[Embodiments of the invention]

An embodiment of the telephone according to the present invention will be described below with reference to the drawings.

l is the main body of the phone (which has an answering machine function), and the front side has numbers 1 to 0 and * and # signs 2a on the left half, and the other half has the auto dial character A. -1, A-2, A-3 character display 2b and abbreviated character display 2c are arranged with dial keys configured so that numbers, symbols, and characters stand out by illuminating them from the bottom surface like a punched material. There is.

Furthermore, as shown in FIG. 2, on the bottom surface of each dial key 2, two light emitting devices 3 and 4 such as light emitting diodes are partitioned by walls 3a and 4a so that their light does not leak from each other. It is located.

The light emitter 3 partitioned by the partition walls 3a, 4a is designed to display only the numbers or symbols 2a, and the light emitter 4 is designed to display only the character displays 2b, 2c. Note that 5 is a tact switch that is turned on by operating the dial key 2.

Reference numeral 6 designates a registration key provided separately from the dial key 2, which is operated when storing a telephone number as an abbreviation or auto-dial.

7 is a handset placed on the side of the telephone body 1, and 8 is a tape storage section for an answering machine.

Next, to explain the block diagram of FIG. 3, 9 is a control circuit that receives the dial key 2 and the registration key 6 as input and performs operations based on the flowchart of FIG. 4, which will be described later;
Reference numeral 10 denotes an illumination circuit that drives each of the light emitters 3 or 4 to turn on and blink according to the output from the control circuit 9.

Next, the operation will be explained with reference to the flowchart shown in FIG.

First, in the standby state, the control circuit 9 outputs a signal to turn on only the light emitter 4, and the light emitter 4 is turned on via the lighting circuit 10. As a result, the number and symbol displays 2a of the dial key 2 are not illuminated, but only the character displays 2b and 2c are illuminated (step Sl). In this state, the control circuit 9 monitors whether or not the registration key 6 has been operated (step S2). Here, when the registration key 6 is operated, the light emitter 4 is blinked via the lighting circuit 10, and therefore, The character displays 2b and 2c are flashed and illuminated (step S3). In this state, the control circuit 9 monitors whether any of the auto dials A-1 to A-3 of the dial keys 2 has been operated (step S4), and if not, whether the shortcut key has been operated or not. (Step S5).

In step 4 described above, auto dial A-1 to A-A
-3 is operated, the light emitter 4 is turned off and the illumination of the display 2b of the auto dials A-1 to A-3 and the shortening display 2C is stopped (step S6). At the same time, the control circuit 9 inputs an output to the illumination circuit 10 to cause the light emitter 3 to blink, thereby blinking the numbers and symbols (step S7).

Next, the control circuit 9 monitors whether the registration key 6 has been operated (step S8), and if the registration key 6 has not been operated, it monitors whether the dial key 2 has been operated (step S9). . Then, when the telephone number is registered (step 310) and the operation of the registration key 6 is detected in step S8, the control circuit 9
Then, the voice recognition circuit sends out the digits of the registered telephone number (step 5ll), and the auto-dial registration is completed.

On the other hand, in step S4 described above, auto dial A
If -1 to -3 are not operated and the shortcut key is operated in step 5, the light emitter 4 is turned off and the illumination of the display 2b of auto dials A-1 to A-3 and the shortcut display 2C is stopped. At the same time, the light emitter 3 is blinked at high speed to illuminate the number and symbol display 2a at a high blinking cycle (step 512).
. In this state, the control circuit 9 monitors whether or not the dial key 2 is operated (step 513), and when the dial key 2 is operated, the process returns to step S7,
The light emitter 3 blinks at a slower speed than the above-mentioned high-speed blinking, and the following operations are used to register a telephone number by abbreviation.

In addition, in the above explanation, we explained about registering a telephone number, but in the case of a telephone with an answering machine,
A mode changeover switch is provided, and by operating this mode changeover switch, it can also be applied to change the modes necessary for answering machines such as playback and recording displayed on the half of the number and symbol display 2a. .

[Effects of the Invention] As described above, the present invention forms normal dial characters and displays indicating other operation modes on the dial key, and
Two light emitters are arranged on the back side of the dial key, and when the dial key is used for operating numbers, one of the two light emitters is turned on to illuminate only the numbers, and when the dial key is used for operating numbers, one of the light emitters is turned on to illuminate only the numbers, and when the dial key is used for operating numbers, one of the light emitters is turned on to illuminate only the numbers. When using the phone, other light emitters are turned on to illuminate only the mode, which allows the phone to be made smaller and lower in cost, as well as providing good operability even when the dial keys are used for multiple functions. It has the following effects.
