Abstract

PURPOSE:To recognize that the titled radio equipment is brought into the calling state after the calling operation is started by allowing an operation processing means to respond to a call request signal and generate an output signal representing the calling state and allowing a display means to display the generation. CONSTITUTION:A microcomputer MC20 conducts a necessary operating processing by call request and brings a communication control circuit 40 into the standby state. When the user generates a call request signal from a call request switch 11 during the processing of this operation, the MC20 generates an output signal (b) and searches an idle channel in cooperation with the communication circuit 40. When the signal (b) is generated, an OR gate 50 responds to the pulse (a) from an AND gate 80 produced in cooperation with an oscillating circuit 70 based on the going-out signal (c) from the MC20 and a display command signal (d) is generated. Then a driving circuit 100 responds to the signal (d) and allows a display 110 to be lighted.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a simple radio device, and more particularly to a personal radio device suitable for wirelessly communicating with each other based on a predetermined group number.

Conventionally, in this type of personal wireless device, when transmitting wirelessly to the other party, the device performs a call operation based on the operation of a call request switch during standby mode, and then becomes ready to talk to the other party. There are disadvantages in that it takes a long time to complete the process and it is unclear whether or not the call operation state has been reached.

The present invention has been made in response to the above-mentioned problems, and its purpose is to provide a personal wireless device with
The object is to be able to recognize when a calling operation state is reached after the start of a calling operation.

In order to achieve this purpose, the structural features of the present invention, as illustrated in FIG. operating means 2 which generates a call request signal when the radio communication control means 1 is in standby mode; a second arithmetic processing means 4 which performs arithmetic processing so as to cause the wireless communication control means 1 to make a call operation based on the call request signal when the call request signal is generated from the call request signal; a sixth arithmetic processing means 5 which performs arithmetic processing to search for a free call channel, and when it finds the free call channel, sets the free call channel and generates an output signal representing a call enabled state; In the personal wireless device, the second arithmetic processing means 4 generates an output signal indicating the calling state in response to the call request signal, and the display means 6 is adapted to display that a call is being made in response to an output signal from the second arithmetic processing means 4.

By configuring the present invention in this way, υ, as described above, in response to the output signal generated from the second arithmetic processing means 4 based on the operation of the operation means 2, the display means 6 displays the information that the personal wireless device Since the display indicates that the personal wireless device is in the calling operation state, the user of the personal wireless device must be sure to recognize that the personal wireless device is in the calling operation state after operating the call request, based on the display contents of the display means B. As a result, the user can wait without feeling irritated until the call becomes available. In such a case, the display means 6 for displaying the call-ready state is also used to display the calling operation state, which is effective in saving the display means.

Hereinafter, one embodiment of the present invention will be explained with reference to the drawings.
The figure shows a block circuit of a personal wireless device according to the present invention, and this personal wireless device includes an operation display section 10 and a microcomputer 20 connected to the operation display section 10. The operation display unit 10 has a call request switch 11 and other various operation switches and display lamps, and the call request switch 11 generates a call request signal when operated. A computer program stored in advance in
According to the flowchart shown in FIG. 2, the operation display section 10
, is repeatedly executed in cooperation with the Brestokes isotiro 1 of the microphone 6o and the communication control circuit 4o, and during such execution, as described in the explanation of the operation below, the communication control circuit 40° AND gate 80 and OR gate Performs various arithmetic processing necessary for controlling 9o. Communication control circuit 4
゜ performs various operations such as standby operation, calling operation, etc. under the control of the microcomputer 20. Among them, the same symbols 50 and 60 indicate a transmitting and receiving antenna and a speaker, respectively.

AND gate 80 is connected to microcomputer 2° and oscillation circuit 70, which generates a series of pulses a (see FIG. 6) having a predetermined frequency.

The AND gate 8o receives an output signal b (see FIG. 6) from the microcomputer 2o, which will be described later, indicating that the personal wireless device is in the calling operation state.
Upon receiving each pulse a from the oscillation circuit 70,
Assigned to R gate 90. OR game) 90 outputs an output signal C(
6), the display command signal d responds to each pulse a from the AND gate 80 and indicates that a call is being made with a duty ratio defined by the cycle of the pulse a. (see FIG. 6), and also generates a display command signal .theta. (see FIG. 6) in response to the output signal C when the output signal C disappears, indicating the call-ready state.

The drive circuit 100 generates a first drive signal at the duty ratio of the signal d in response to a display command signal d from the OR gate 9o, and generates a second drive signal in response to a display command signal θ from the OR gate 90. Generates a drive signal. Display 11
0 is attached to the personal wireless device, has a semiconductor light emitting element, and causes the semiconductor light emitting element to emit light intermittently at the duty ratio of the first drive signal in response to a first drive signal from the drive circuit 100. At the same time, the drive circuit 10
The semiconductor light emitting device continuously emits light in response to a second drive signal from zero.

In this embodiment configured as described above, when the personal wireless device is activated, the microcomputer 2
0 starts the computer program in step 120 according to the flowchart of FIG. is in standby mode.

Therefore, during the determination as rNOJ in step 122 and the repetition of the calculation process in step 121,
When the user of the personal wireless device generates a call request signal from the call request unit 11 in order to talk to the 4th person, the microcomputer 20 in step 122 generates a call request signal based on the call request signal. Then, in step 126, an output signal b (see FIG. 6) is generated, and by repeating the calculation that circulates through the corresponding backward terminals 124 and 125, an idle call is determined in cooperation with the communication control circuit 4o. Search for the channel.Also, as mentioned above, when the output signal is generated from the microcomputer 20, the OR/7
'-) 90 generates a display command signal d() in response to a series of pulses a from an AND gate 8o generated in cooperation with an oscillator circuit 7° upon the disappearance of an output signal C from a microcomputer 2°. (see Figure 6). Then, the drive circuit 100 generates a first drive signal in response to the display command signal d from the OR gate 90, and in response, the display 1
The light is emitted intermittently at a duty ratio of the first drive signal of 10. This allows the user to confirm that the personal wireless device is in a calling operation state.

When the microcomputer 20 selects and sets an empty call channel in cooperation with the communication control circuit 40 during the cyclic calculations in steps 124 and 125 as described above,
The determination in step 125 is "YESJ". This means that the personal wireless device is now ready for communication. Next, the microcomputer 2
At step 126, the output signal C disappears to generate an output signal C (see FIG. 6), which is applied to the OR gate 90.

Then, the OR gate 90
When the output signal S disappears, a display command signal e (see FIG. 6) is generated in response to the output signal C, and accordingly, the drive circuit 100 generates a second drive signal. For this reason,
The display device 110 continuously emits light in response to the second drive signal from the drive circuit 100, and as a result, the user can make the personal wireless device ready for a call without having to wait for a voice response from the other party. This can be confirmed correctly. After that, the microphone 6 was operated under the control of the press talk unit 61.
All you have to do is talk to the other party using 0.

In the above embodiment, the display unit 110 distinguishes the calling operation state of the personal wireless device from the call-ready state.
However, instead of this, for example,
A buzzer circuit or other various display means may be employed as the display 110.
