Description

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

[Conventional technology]

The dial keys (push type) of conventional telephones are
It can be used as a number by only using it to operate the telephone number of the other party who makes a call, or when storing the abbreviated number in the memory built into the telephone or when storing auto dial. There was nothing else. Here, abbreviation refers to operating both the abbreviated operation key and the dial key provided separately from the dial key to call the telephone number, and the autodial is separate from the dial key. By operating one of the plurality of provided auto dial keys, the telephone number corresponding to the key is read out.

[Problems to be Solved by the Invention]

By the way, the dial keys in the above-mentioned conventional telephone have a role only as a numeric operation, and when transmitting a telephone number by shortening or auto dialing, it is necessary to operate other operation keys provided in addition to the dial keys. I have to. That is, these operating keys must be located on the phone separately from the dial keys, and therefore
There is a problem in that the cost is increased because the number of parts increases as it hinders downsizing of the telephone.

[Object of the Invention]

The present invention is intended to solve the above-mentioned problems, and an object of the present invention is to reduce the size and cost of a telephone by enabling the dial keys to be used for numerical operations and other operations. It is possible to reduce the brightness, and when it is used as a number operation, only the numbers are illuminated, and when it is used as another operation, the letters representing other operations are illuminated, so that the illumination is performed by identifying. The purpose of the present invention is to provide a telephone having good operability even if the dial keys are used for multiple functions.

[Outline of Invention]

The present invention is intended to achieve the above-mentioned object. The gist of the present invention is to form a normal dial character and an indication indicating another operation mode on the dial key, and to provide two lights on the back surface of the dial key. When the dial key is used for number operation, one of the two light emitters is turned on to illuminate only the number, and when used for other modes, the other light emitter is turned on. It is designed to illuminate only the mode.

Example of Invention

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

Reference numeral 1 is a telephone body (having an answering machine function). Numbers 1 to 0 and * and # symbol display 2a are on the left half of the surface, and the other half is an auto-dial character A. -1, A-2, A-3 Character display 2b and shortened character display
The dial keys are arranged so that the numbers, symbols, and characters are embossed by illuminating the lower surface of 2c like blanking.

Further, as shown in FIG. 2, on the lower surface of each of the dial keys 2 described above, light emitting devices 3 and 4 such as two light emitting diodes are provided on the image wall 3a.
They are arranged in a state of being divided by 4a so as not to leak light from each other. The light emitter 3 partitioned by the partition walls 3a and 4a is adapted to display only the numeral or symbol display 2a, and the light emitter 4 is adapted to display only the character display 2b and 2c. A tact switch 5 is turned on by operating the dial key 2.

Reference numeral 6 is a registration key provided separately from the dial key 2 and is operated when the telephone number is shortened or stored as auto dial.

Reference numeral 7 is a handset mounted on the side surface of the telephone body 1, and 8 is a tape storage portion for an answering machine telephone.

Next, referring to the block diagram of FIG. 3, reference numeral 9 is a control circuit for inputting the dial key 2 and the registration key 6 and performing an operation based on the flowchart of FIG.
Reference numeral 10 denotes the light emitter 3 described above according to the output from the control circuit 9.
Alternatively, it is an illumination circuit for driving and blinking 4 separately.

Next, the operation will be described with reference to the flowchart of FIG.

First, in the standby state, the control circuit 9 outputs a signal for turning on only the light emitting device 4, and the light emitting device 4 is turned on via the lighting circuit 10. As a result, the number of dial key 2,
The symbol display 2a is not illuminated, and only the character displays 2b and 2c are illuminated (step S1). In this state, the control circuit 9 monitors whether the registration key 6 has been operated (step S2),
Here, when the registration key 6 is operated, the light emitter 4 blinks via the illumination circuit 10, and accordingly, the character displays 2b and 2c are blinked and illuminated (step S3). In this state, the control circuit 9 causes the automatic dials A-1 to A-3 of the dial key 2 to operate.
It is monitored whether or not any one of them has been operated (step S4), and when not operated, it is monitored whether or not the shortcut key has been operated (step S5).

In step 4 described above, auto dials A-1 to A
-3 is operated, the light emitter 4 is turned off and the display 2b and the shortened display 2c of the auto dials A-1 to A-3 are displayed.
Stop the lighting of (step S6). At the same time, the control circuit 9 inputs an output for blinking the light emitter 3 to the illumination circuit 10 to blink the numbers and symbols (step S).
7).

Next, the control circuit 9 monitors whether the registration key 6 has been operated (step S8), and when the registration key 6 has not been operated, monitors whether the dial key 2 has been operated (step S9). ). Then, when the telephone number is registered (step S10) and the operation of the registration key 6 is detected in the step S8, the control circuit 9 causes the voice recognition circuit to recognize the number of the registered telephone number. It is sent (step S11), and the registration of the auto dial is completed.

On the other hand, in step S4 described above, the auto dial A-
If 1 to A-3 are not operated and the speed key is operated in step 5, the light emitter 4 is turned off and the auto dial A is turned off.
-1 to A-3 display 2b and abbreviated display 2c are stopped, and the light emitter 3 is flashed at high speed to display numbers and symbols 2a.
Is illuminated at a high-speed blinking cycle (step S12). In this state, the control circuit 9 monitors whether or not the dial key 2 is operated (step S13), and when the dial key 2 is operated, the process returns to step S7 described above, and the light emitter 3 is slower than the high-speed blinking. Blinking, and the following is for registering a telephone number by shortening by the above-mentioned operation.

In the above explanation, the telephone number registration was explained, but in the case of a telephone having an answering machine,
By providing a mode changeover switch and operating this mode changeover switch, it can be applied to the mode changeover necessary for answering machine such as reproduction and recording displayed on the half of the numeral and symbol display 2a. .

〔The invention's effect〕

According to the present invention, as described above, the dial keys are provided with the normal dial characters and the display showing other operation modes.
Two light emitters are arranged on the back surface of the dial key, and when the dial key is used for numeral operation, one of the two light emitters is turned on to illuminate only the numeral and used for other modes. When this is done, the other light emitters are turned on to illuminate only the mode, so the phone can be made smaller and the cost can be reduced, and the operability is good even if the dial keys are used for multiple functions. It has the effect of.
