As described above, in the conventional hands-free notification device, a control signal for specifying the operation of the hands-free device sent from the wireless device is set for each operation, and the wireless device is set up. By operating a plurality of keys provided, a desired control signal is generated, and the hands-free device receiving this control signal performs the operation designated by the reception control signal.

However, such a hands-free reporting device sends a control signal designating the operation of the hands-free device,
Since it is necessary to prepare for each operation, it is necessary to provide a plurality of keys or a plurality of signal generation sources,
Not only is the configuration complicated, but there is a cost problem.

Therefore, an object of the present invention is to provide a hands-free reporting device having a wireless structure that can specify a plurality of operations with a simple structure.

[0010]

In order to solve the above-mentioned problems, a hands-free reporting device according to the present invention includes a wireless device for transmitting a control signal, a detection unit for detecting a state including an incoming call state and a call state, and the control described above. A hands-free device having a receiving unit that receives a signal and a control unit that executes a predetermined operation according to the state when the receiving unit receives the control signal is configured.

[0011]

In the present invention, when the remote control signal is received,
The hands-free device detects the current operating state (for example, incoming call, talking, unused state, etc.), and executes an arbitrary operation according to the detection result.

[0012]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a configuration block diagram showing an embodiment of a hands-free notification device according to the present invention. In the present embodiment, a hands-free device 1 for connecting to a telephone line (outside line) to make a call and a wireless device 2 for generating a radio signal.
Composed of and. In the hands-free device 1, the radio signal transmitted via the transmitting antenna 21 of the wireless device 2 is received by the receiving antenna 11 and sent to the wireless unit 14. The wireless unit 14 processes the received signal received by the antenna 11 and sends it to the control unit 13. In the wireless unit 14,
A control signal generator (not shown) that generates a predetermined control signal is built in.

On the other hand, the line status monitoring unit 15 monitors the status of the line and the hands-free device 1 itself, and determines whether the status of the line is, for example, incoming, talking, or normal. Therefore, an incoming call detecting unit 151 and a call current detecting unit 152 are provided for that purpose. If the incoming call detection unit 151 detects the incoming call, it is determined that the incoming call is in progress, and if the call current detection unit 152 detects the notification current, it is determined that the call is in progress. Further, the incoming call detection unit 151 and the call current detection unit 152
However, when none of them is in the detection state, it is determined that the telephone is in the unused state.

The control unit 13 receives a signal from the radio unit 14, and when the signal is a predetermined control signal, the control unit 13 determines whether the control signal exists and the status determination result from the line status monitoring unit 15. Based on this, a predetermined operation described below is executed. The control unit 13 controls the call circuit unit 12 to perform operations such as answering an incoming call, ending a call, and auto dialing.

FIG. 2 shows a main operation processing procedure in this embodiment. Referring to FIG. 2, the antenna 1
When the wireless unit 14 receives a processed signal from the received signal from the line 1, the line state monitoring unit 15 causes the incoming call detecting unit 15
1. The current state is determined based on the detection signal from the call current detection unit 152 (step S1). In accordance with this determination result, the control unit 13 controls the call circuit unit 12 to perform various corresponding operations. That is, when the determination result is the incoming call state, the response operation is executed (step S2), and when the call state is the line disconnection operation for ending the call is executed (step S3), it is also in the unused state. At times, a notification operation is executed (step S4). The notification operation in step S4 is an auto-dial operation for sending a dial number set in advance in the auto-dial circuit unit (not shown) in the hands-free device 1. Obviously, other arbitrary operations besides the above can be set according to the current state.

As described above, in the present embodiment, when the remote control signal is received, the hands-free device 1 side judges the present operating state (for example, incoming call, talking, non-use state, etc.) and responds to the judgment result. Since any operation can be performed, the wireless device 2
Since only one type of signal from the side is required, it is not necessary to provide a plurality of keys for various controls and a signal generation source on the wireless device side as in the conventional case, and the configuration is extremely simplified. Further, since the functions of the incoming call detection unit 151 and the call current detection unit 152 that form the line state monitoring unit 15 are installed in a normal telephone, the load on the hardware is extremely small, and It is extremely advantageous in terms of structure and cost.
