Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is suitable for use in mobile radio telephone devices such as conventional cordless telephones, for use in charging stands for handy radios that originally only have a charging function, for answering machine recording and playback, facsimile modulation/demodulation, and hands-free calling. Each of the above functions is equipped with a circuit that performs any or all of the above functions, as well as those mechanisms and a battery charging function, and is installed on the side of the handset at an arbitrary location away from the base unit that is directly connected to the terminal of the telephone line. The present invention relates to a mobile radio telephone device equipped with a multifunctional charger, characterized in that it can be operated to bring out its functions.

0002

[Prior Art] Normally, a subscriber telephone connected to a terminal of a telephone line is used as a base unit, and a handy radio equipped with a movable self-contained battery is used as a slave unit. In order to communicate over the line, the subscriber telephone set of the base unit is connected to the telephone line via a connecting device that has at least the functions of opening/closing the telephone line, making and receiving calls, and wireless transmission/reception functions. ing.

[0003]Various functions added to a cordless telephone equipped with the above-mentioned minimum basic functions, such as an answering machine recording/playback function, a modulation/demodulation function necessary for transmitting/receiving images such as a facsimile, or a hands-free function that allows you to go off-hook without picking up the handset. In order to provide this, it is generally added to the subscriber phone connected to the telephone line, that is, the base unit, so the above functions can only be performed in the fixed position where the base unit is installed. I can't do any operations for this purpose.

Next, looking at cordless handsets, portable handy radios have a built-in secondary battery, and are usually placed on a charging stand for supplementary charging and connected electrically via a connection. When making a call, the handy radio is left on the charging stand or picked up and operated, and it is within the radio range of the base unit and the commercial power supply of the charging stand is used. It is possible to move freely if it is at the derived position. Here, the above-mentioned charging stand incorporates an AC-DC converter and adopts a separate charging method that only serves to charge the handy radio's own secondary battery.

[0005] Therefore, the above-mentioned conventionally known multi-function mobile radio telephones have various functions consolidated on the base unit side, and the separate charging method only has limited functions for the sole purpose of charging. It is something.

[0006]

[Problems to be Solved by the Invention] The present invention is characterized in that while conventional multifunctional mobile radio telephone devices can only be operated on the subscriber telephone, that is, on the base unit side, the present invention is installed only for the single purpose of charging. In view of the inconvenience of using various functions that separate charging methods are being added one by one, we have decided to replace the conventional radio link at the charging stand on the handset side, which can be moved to a location with commercial power in a radio range far away from the base unit. calls through,
The purpose is to provide various functions such as answering machine recording and reproducing, facsimile transmission and reception, and hands-free calling, thereby expanding economic flexibility and serviceability to meet consumer needs.

[0007]

[Means for Solving the Problems] The present invention provides a single-function, separate type charging stand for charging the built-in battery of a conventional handy radio as a slave device, which can be used to reproduce answering messages, modulate and demodulate facsimile transmission and reception, and perform hands-free functions. The circuit that performs the various telephone functions is housed together with the charging circuit, and these mechanisms are attached.

An embodiment of the present invention will be described below with reference to the drawings. Figure 1 is a configuration diagram of an embodiment of a cordless telephone device using a conventional separate charging method. It is sufficient that the base unit consists of a connection device 2 that includes various circuits and parts for calling and calling, and a wireless transmitter/receiver, but as shown in the figure, a main unit equipped with a push-button switch and a curl cord can be used as a subscriber telephone. There are also devices in which the connected device is mounted on the above-mentioned connecting device.

Next, the handset is placed on the charging stand 6 and recharged.The handy radio 5 has a transmitting/receiving circuit, a secondary battery, a handset, a dialer circuit, a push button switch, a power input switch, and an indicator lamp. Equipped with circuits, parts, and connections such as The structure is as follows.

FIG. 2 shows an example of the circuit configuration of the multifunctional effect circuit 7 to be housed in or attached to the charging stand according to the present invention. It is converted into automatically adjusted direct current by a power supply conversion/adjustment section 76 consisting of a voltage regulator, and is then sent to the CPU 71 and each function provision section 7 described below.
5 and charging control circuit 72 via a power supply path. A receiving circuit 73 and a transmitting circuit 74 for transmitting and receiving data of the handy radio are connected to the CPU. T1 and T2 are charging terminals, T3 and T4 are data transmission/reception line terminals, and T5 and T6 are audio line terminals. Both terminals are provided on the charging stand and make electrical contact with the connection part of the handy radio. It is designed to maintain

[0011] In the case of facsimile communication as an example of image transmission, each of the function imparting units 75 stores a modular modem so that it can be replaced in a charging stand, and the mechanism constituting the entire device is installed in the charging stand. By attaching it near a commercial power source, it becomes possible to operate the handy radio while connected to the charging stand at a location separated from the base unit.

[0012] Furthermore, when adding an answering machine recording/playback function, the electric circuits required for audio input/output and recording/playback are removably housed in the multifunction effect circuit as each function providing part, and the recording medium is attached and driven. The mechanism etc. may be attached outside the charging stand.

[0013] To make a call between the handy radio and a base unit to an outside line or a call between handsets, if the built-in battery is in a charged state, remove the handy radio from the charging stand and move it, or charge it. The fact that you can communicate while connected to the stand is the same as before.

[0014]

[Effects of the Invention] Conventional multi-function wireless telephones can only be used by the base unit to which the telephone line is connected, and if it has a slave unit, it cannot be used without visiting the location where the base unit is installed. On the other hand, according to the present invention, various functions such as answering machine replay, facsimile communication, hands-free calling, etc. are added to the charging stand in the separate charging method, thereby making it easy to successively expand the system as a communication system. We can respond to a wide variety of consumer needs with great flexibility. In addition, despite the addition of various functions, the handy radio remains unaffected in any way.
It is possible to further reduce the size and weight. Therefore, in response to requests for adding new functions, it is possible to add various functions to a basic separate rechargeable cordless telephone device at the lowest cost, and to greatly expand the handling and operability of the handset. It is possible.
