Abstract

PURPOSE:To offer the convenience with ease of handling by sounding sequentially a voice in response to a stored telephone number and using the voice so as to call an opposite party. CONSTITUTION:In dialing a telephone number from a dial card, a transmission switch 4 is operated to apply a power from a battery 2 to an operation control circuit 5. Then the operation control circuit 5 reads a data stored in a memory 6 and the voice having 9 kinds of frequencies corresponding to numeral '1'-'9' is sounded sequentially from a piezoelectric speaker 3 based on the said data. During this time, the transmission switch 4 is kept on by a finger and when a series of operations are finished, the dialing is finished by detaching the finger from the switch 4.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field 1] The present invention relates to a dial card for a touch-tone phone that can automatically dial without pressing a button.

[Background Art] Conventional touch-tone telephones that dial by sound have a special function that allows you to call the other party by pressing 10 buttons instead of 3 by connecting the telephone line with a computer at a central telephone office. We offer services such as speed dial, which allows you to call the other party just by pressing a button.

However, the user still had to press a push button, and the user had to either memorize the telephone number or look at a notebook in which the telephone number was written while making a call.

[Object of the Invention] The present invention 1 has been made in view of the above-mentioned points, and its object is to provide a dial card that allows dialing without pressing a push button.

[Disclosure of the Invention] (Example 1) FIGS. 1 and 2 are diagrams showing an example of the present invention,
[
A dial card having a cash card size of 851 mm x width 54 mm x thickness 0°8+nm is disclosed. Specifically, as shown in FIG. 2, there is a piezoelectric speaker 3 that emits a telephone number as a sound, a memo +75 that stores data corresponding to the telephone number, and a piezoelectric speaker 3 that reads data from this memory 6 and transmits the telephone number. The arithmetic control circuit 5 generates power by driving the arithmetic control circuit 5, the transmission switch 5-4 operates the arithmetic control circuit 5, and power is supplied to the arithmetic control circuit 5 via the transmission switch 4 while the transmission switch 4 is turned on. The above-mentioned parts are arranged in a cash card-sized casing 1, as shown in FIG.

For the battery 2, a vapor battery, a solar battery, or the like is used to reduce the thickness. Here, the memory 6 may be a one-shot PROM, an EEPROM, or a CMO8RAM with battery backup. Further, in this embodiment, a dial data input contact 7 for writing data corresponding to a telephone number into the memory 6 is provided.

The operation will be explained below. First, a method of writing data corresponding to a telephone number into the memory 6 will be explained.

This writing is done from dial data input contact 7,
For example, data is written to the memory 6 serially or in parallel. Here, the above data is dial data of BCD code.

The operation of reading the data stored in advance in the memory 6 as described above and sequentially emitting sounds at a frequency indicating a telephone number from the piezoelectric speaker 3 will be explained. To dial a telephone number from the dial card, operate the transmitter switch 4. By operating the transmitter switch 4, power is supplied from the battery 2 to the arithmetic control circuit 5 via the transmitter switch 4, and the arithmetic control circuit 5 is operated. Circuit 5 operates. Then, the arithmetic control circuit 5 reads the data stored in the memory 6,
Based on this data, numbers 1 to 9 are output from piezoelectric speaker 3.
It sequentially emits sounds having nine different frequencies corresponding to the following. During this time, the transmission switch 4 is held in the ON state with a finger, and when the above series of operations is completed, the dialing operation is completed by releasing the finger from the transmission switch 4. In this way, the internal circuit operates only when the operation switch 4 is pressed, thereby saving power from the battery 2.

It goes without saying that when a memory IC or the like which requires battery backup is used as the battery 2, it is necessary to constantly supply power to the memory 6 by the battery 2 as shown in FIG. Since this dial card is the size of a cash card, it is easy to carry and can be carried in a wallet or business card case. Furthermore, this dial card can be used as a business card with your name printed on it and your phone number stored therein, or as a membership card with your golf tag phone number stored on it.

(Embodiment 2) FIGS. 3 and 4 are diagrams showing other embodiments of the present invention. In Embodiment 1, the memory 6 was provided, but in this embodiment, as shown in FIG. In this way, the casing 1 of the dial card is provided with a dial data punch part 8 in which a bunch hole 9 is punched directly with BCD code data corresponding to a telephone number.

Since the other parts are the same as those in the first embodiment, only the dial data punch section 8 will be explained.

The dial data punch section 8 is connected to the arithmetic control circuit 5 using a copper foil such as a printed pattern, as shown in FIG. Specifically (the number of output terminals OUT, -0UT according to the number of the dial of the upper arithmetic control circuit 5)
In order to indicate n and input data in BCD code, four input terminals IN are required.

~IN, and the arithmetic control circuit 5 has input terminals IN, -
The output terminals OUT and -0UTn are connected to each of IN4, and a punch hole 9 is formed in a portion indicated by a broken line circle in FIG. And the above output terminal OUT.

~○UTn is normally a high impedance input terminal IN,
~IN, output terminal OU when importing dial data
High level pulses are output in order from T. Further, the input terminals IN, ~IN, are normally pulled down, and pulses are inputted in synchronization with the pulses generated from the output terminals OUT, ~OLJ T n.

[Effect of the Invention 1] As described above, the present invention sequentially produces sounds corresponding to the stored telephone numbers and calls the other party before the above.
You can dial using the sound emitted from the dial card.
There is no need to press the usual push button, and since the other party's phone number is stored on this dial card, you can eliminate the hassle and hassle of memorizing the phone number yourself or writing it down in your notebook. This has the effect of making it easy to use and convenient.
