Abstract

PURPOSE:To simplify the construction of a telephone set, to make the size small and to attain light weight, by providing a pressure sensing surface on an upper surface of the telephone set, drawing a telephone number with a finger tip and transmitting the telephone number to an exchange station. CONSTITUTION:In drawing a numeral with a suitable size with a finger tip on a matrix pressure sensing surface cover 3 with a little depression, a matrix key element under the cover is depressed, and through the sequence of depressed loci of each key element depressed, just after the drawing of the said numerals, a converter 7 generates signals of the said numerals, and the signals are displayed on a number display section 5, allowing to transmit the telephone numbers one by one while confirming them.

Description

[Detailed Description of the Invention] The present invention relates to a telephone set, and unlike a dial type or button type telephone set, it is possible to draw telephone number numbers of a predetermined size on a pressure-sensitive surface provided on the top surface of the telephone set with a fingertip. The matrix pressurized key elements below the pressure-sensitive surface are pressed down, and the telephone number signal outputted according to the sequence of the pressed locus of the key elements is transmitted to the exchange.

m by dial display from 0 to 9 or button
When making a call using a single device, the former requires time to move the rotary plate back and forth, while the latter saves time, but has the inconvenience of having to search for the position of the number on the button.

The present invention eliminates the dial or key button device installed on the top surface of the telephone, and uses a pressure-sensitive surface f provided on the top surface of the telephone: a matrix for inputting and outputting numbers, and numerals drawn on the matrix. This system converts arithmetic digits into signals using a converter combined with the matrix and sends them to a switching center to call the other party.The purpose of this system is to simplify and downsize the structure of telephone equipment, The purpose is to make it lighter.

Describing an embodiment, 1 indicates a telephone according to the present invention, 2 a number of pressure-sensitive elements of a pressure-sensitive matrix provided on the top surface of the telephone, and 3 a pressure-sensitive surface covering the entire pressure-sensitive surface of the matrix. The cover 3 has a plurality of easy-to-discernible sample numbers 4 displayed on the cover 3 in dotted lines or in a color different from the ground color to indicate the size of the number to be drawn with a fingertip. . The pressure-sensitive surface cover 3 is not essential, and the upper surface of the pressure-sensitive element 2 may be made into an arcuate convex surface so that a finger will not get caught, and numbers may be drawn directly on this surface with a fingertip. Reference numeral 5 designates a number display section using a liquid crystal display or the like for electrically displaying the numbers drawn on the pressure-sensitive surface.

In the embodiment, the matrix pressure sensitive element 2 has key elements finely and evenly arranged vertically and horizontally on its lower surface.
, a converter circuit made of a semiconductor is operated, and the converter circuit is installed in a converter 7 on a support stand 6 in the telephone, and the pressure sensitive surface cover 3 is activated by a signal output from the converter circuit. The numbers drawn with the tip of the finger are to be displayed on the number display section 5 and a signal is transmitted to the telephone exchange in a known manner. In the figure, 8 is a cancel push button for erasing the wrong number if the wrong number is drawn, and 9 is a lighting element that shows the contour of the matrix pressure-sensitive surface.

If you draw a number of an appropriate size on the matrix pressure sensitive surface cover 3 by pressing it slightly with your fingertip, you can see the number at the bottom.
The Rick key element is pressed down, and the sequence of the pressure locus for each pressed key element causes the converter 7 to generate a signal of the number immediately after the number is drawn, and the signal is displayed on the number display section. , you can make a call while checking each phone number one by one. As long as the drawn numbers are not random, apply a pressure trajectory sequence that will emit a signal.
Of course, 4UEs should be configured between the element matrix and the converter.

According to this invention, by designing an ultra-small semiconductor circuit, only a converter for converting pressure-sensitive digits into a telephone number signal is required inside the telephone, thereby making the speaker smaller and lighter and providing an innovative form. Get the effect you want. In addition, when trying to make a call after the lights are turned off at night, even if the room is dark, if you memorize the number, the lighting element 9 will indicate the contour of the pressure-sensitive surface, so you can use it by drawing a number on it. It is something.
