Description

Description: TECHNICAL FIELD The present invention relates to a storage device.

[Prior art]

The following description will be given using a push-button telephone, which is an example of a storage device.

With the spread of outpulse type push-button telephones in recent years, a telephone number is registered as a shortened number in a memory circuit built in the telephone, and a predetermined telephone number is simply pressed by pressing several push buttons corresponding to the shortened number. , A telephone having a function of automatically sending a dial pulse corresponding to the above has appeared, and an integrated circuit for a telephone having the above-mentioned function with the built-in storage circuit is
Generally called a repertoire dialer.

FIG. 3 shows a flowchart for registering a telephone number in a conventional repertoire dialer. In the conventional push button operation method, first, in order to indicate that the operation to be performed is the registration of a telephone number, one specific push button (*
Or #) and then the push button of the predetermined telephone number. When all the telephone numbers have been pressed, the specific push button is pressed again, and then the one-digit or two-digit numeric push button corresponding to the shortened number is pressed. At the same time that the last push button is pressed, the integrated circuit operates to store the data of the telephone number in the address corresponding to the abbreviated number in the storage circuit.

However, in the conventional operation method, even if you notice that you are trying to register a wrong telephone number to register or you are trying to register to an abbreviated number that you do not want, you can not correct it in the middle of the registration operation, You must either continue until or cancel by turning the hook switch ON / OFF.
However, it is cumbersome to operate the handset one by one to cancel, and on the other hand, a part of the regulations regarding the technical standards related to telephones says, "The DC circuit should not be closed except for the purpose of making a call or communication." There is a stipulation, and there is a drawback that it is against the stipulation to go off-hook only for canceling the telephone number registration.

〔Purpose〕

The present invention solves such a drawback, and an object thereof is to enable cancellation during the registration operation by operating a push button without operating a hook switch.

〔Overview〕

FIG. 1 shows a flowchart of the push button operation at the time of registering the telephone number according to the present invention. The basic operation method is the same as the conventional one, but as an example of the setting means, a detecting means for detecting that the specific push button is pressed twice or more continuously is added, and the cancel operation is performed by the output of the detecting circuit. It is characterized by performing.

〔Example〕

FIG. 2 shows an embodiment of the detection circuit for specifically realizing the present invention. In the figure, delay flip-flops 1 and 2 change the state of output Q in synchronization with the fall of clock input C, and both flip-flops are conventionally connected as a binary counter. A pulse signal S is applied as a clock input to the first flip-flop 1 each time the specific one push button is pressed, and a pulse signal A is generated each time any one of the numeric push buttons is pressed. Are connected to reset both flip-flops 1 and 2. With this connection, the flip-flop is reset if the numeric pushbutton is pressed while the specific pushbutton is pressed twice or more, and the flip-flop is reset if the specific pushbutton is pressed twice consecutively. The output Q of the second flip-flop 2 is inverted from low level to high level. The output Q of the second flip-flop 2 is the differentiation circuit 3
The differential pulse is output in synchronization with the output Q being inverted from the low level to the high level. The differential pulse may be replaced with a cancel signal by a conventional hook switch.

〔effect〕

As described above, according to the present invention, when erroneous data is input during the registration operation, new erroneous input data is not left with the existing button without setting new mode and turning ON / OFF the hook switch. Since the data can be deleted and then re-entered as it is, it is possible to securely delete and register the data within the technical standards to be observed. Moreover, since the operation of surely erasing and re-registering the data is performed at one time with the existing registration operation button, there is no need to add a cancel button, which saves space and space. This has the effect of increasing the flexibility of cost design.

The present invention can be applied not only to a pulse dialer with a repertoire memory, but also to a tone dialer with a repertoire memory.
