Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a device capable of transmitting information using communication information.

[Prior Art] Conventionally, a device called a pager has been on the market as one of this type of devices. Although this device has a function of sensing that the person carrying the call is receiving a call, this device cannot determine why the person receiving the call received the call. Therefore, the carrier must either call the caller immediately after receiving the call, or go directly to the caller and confirm the requirements, thereby completing the information transfer. Thus, pagers have the disadvantage of requiring some sort of additional verification means.

[Objective] An object of the present invention is to provide a novel portable information transmission device that eliminates the above-mentioned drawbacks.

SUMMARY OF THE INVENTION An object of the present invention is to provide a portable information transmitting device that can output the requirements requested by the caller by voice or display on the receiving side.

The present invention is provided with a storage unit that stores commonly used transmission information sentences on the receiving side, and can output the transmission information sentence selected by the selection signal included in the received information, and can output the transmission information sentence selected by the selection signal included in the received information. It is an object of the present invention to provide a portable information transmission device that is also capable of outputting information sentences.

[Embodiment] Next, an embodiment of the information transmission device according to the present invention will be described. It goes without saying that this device may have only a transmitting section or both a transmitting section and a receiving section.

The radio waves captured by ANT are transmitted to the high frequency selective amplifier HF.
Only the radio waves in the signal band assigned to the receiving section are amplified. From this amplified signal, a demodulator DEM demodulates a signal specifying the address of the fixed memory ROM where the transmitted information is stored. When the above signal specifies an address in the fixed memory ROM, a time-series signal of phonemes corresponding to vocalization information of the transmission information is outputted from the fixed memory ROM.

Next, an example configured as described above will be explained with reference to FIG.

When the caller wants to tell the person who is carrying the receiver that he or she is going to call the receptionist because there is a visitor at the reception, the caller needs to select the receiver of the person who is carrying the receiver. Operate any of the switches K1 to K5 to change the oscillation frequency of the oscillator OSC2. Therefore, the frequency output from the frequency mixer MIX becomes a frequency that can be received by a certain receiver.

In order to select the message you want to send next, operate the desired message selection buttons MK1 to MK34. Here, the message selection button
When MK1 is operated, a predetermined message stored in the memory ROM can be selected without sending the message itself. When the message selection button MK1 is operated, the encoder ENC generates an encode signal corresponding to that button.
Stored in memory MEM.

Next time the send button TK is operated, the memory
The encoded signal stored in MEM is used as a power amplifier.
