Abstract

PURPOSE:To prevent consumption of a battery by providing a touch sensor to a grip section of a cordless telephone mobile set. CONSTITUTION:The touch sensor 6 is fitted to the grip section 1 of the cordless telephone mobile set. When the operator detaches his hand from the touch sensor 6 even if a hook switch 5 is kept in the state of a calling or power feeding to all circuits and the calling, a power supply circuit to be interrupted when the mobile set is not in use is disconnected after a prescribed time is elapsed by the logical operation of a signal from the sensor 6 and a signal from the hook switch 5. Thus, consumption of the incorporated battery and the continuity of the calling state are prevented and the performance of convenience of the mobile set is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a malfunction prevention device for a cordless local mobile phone, and more specifically, the present invention is a device for preventing malfunctions of a cordless local mobile phone, and more particularly, it prevents the user from forgetting to turn off or operating a hook switch that has a function of cutting off the current that should be cut off when the mobile phone is not in use. 1. Concerning a device to prevent the built-in battery from being depleted and the telephone line left unconnected due to maintenance of the connection due to mistakes; 1. In recent years, it has been used to avoid the complexity of in-house wiring and to make it easier to handle the transmitting/receiving area. Cordless telephones are becoming popular for the purpose of It is.

The mobile device is provided with functions equivalent to those of a general "talk machine" and is also equipped with built-in radio transmitting and receiving equipment and a necessary power source.

Therefore, when the cordless telephone is not in use, it is necessary to cut off the power supply current to the mobile device except for the one for the radio receiver and necessary logic circuits to prevent battery consumption.

However, in order to ensure accurate operation, conventional mobile devices are equipped with a hook switch that is activated by a special operation by a slide switch operator, or a switch devised by the inventors that connects and disconnects by the weight of the mobile device. If you forget to turn off the switch, or if you leave the mobile device on a tabletop with stationery scattered about, the switch may not work, and the battery will be consumed and you will not be able to make a call when you need it. There were some drawbacks such as:

The present invention has been made in order to eliminate the drawbacks of the conventional cordless telephone mobile device as described above, and includes a touch sensor attached to the grip portion of the mobile device, and a signal from the sensor and a touch sensor from the hook switch. According to the logic of the signal, even if the hook switch is maintained in a state of communication or communication and power supply to all circuits, if the operator removes his hand from the touch sensor, the mobile device will not be used after a certain period of time. It is an object of the present invention to provide a malfunction prevention device for a cordless mobile device in which the power source is cut off at times.

Hereinafter, the present invention will be explained in detail based on embodiments shown in the drawings.

FIGS. 1 and 2 show a cordless model to which the present invention is applied, respectively.
It is a front and back external view of a peeking movement suction.

That is, the concave plane 1 of the grip part 1 of a mobile device having a shape similar to a general dial telephone or a handset of a Boussoufon.
A dial button (key pad) 2 is arranged, a receiver 3 is installed at one end of the button, and a microphone 4 for speaking is installed at the other end.Although not shown in the drawings, the inside is equipped with a radio and a power source. be.

As mentioned above, the configuration is as follows: As mentioned above, in order to avoid battery consumption when the device is not in use, it is necessary to cut off the power supply current, except for energizing the wireless receiver, etc.

Therefore, a slide switch 5, for example, is installed at a suitable location on the operating surface of the mobile device, and is turned off except when making a call.

[As mentioned above, operators who are familiar with general telephones often use the slide switch 5.
I forget to cut it.

Therefore, in the present invention, a touch sensor 6 is provided from the back side to both sides of the grip section 1 of the mobile device, and the touch sensor connection/disconnection signal and that of the slide switch 5 are used to temporarily switch the slide switch 5. Even if the user forgets to turn off the switch 5, it is configured to detect that the user's hand has been removed from the touch sensor and shut off the required paper feeding circuit.

For example, a circuit such as the one shown in FIG. 3 may be used for signal processing such as the one shown in FIG.

That is, the signal emitted by the touch sensor 6 is passed through a delay circuit 7 for a required period of, for example, 10 to 20 seconds, and then
1i1H+, is taken as a signal from the self-sliding switch 5, and by combining this signal and the signal from the self-sliding switch 5, the current from the gap 8 is connected and disconnected using an appropriate switching element 9, and the mobile device If the main circuit 10 is configured to perform 11il control, even if the operator forgets to turn off the M'J thrust slide switch 5, the specified power supply current will be cut off after a certain period of time, thereby preventing battery consumption and unintended talking conditions. It is possible to prevent malfunctions such as continuation of the process.

The role of the delayed discharge circuit 7 is to maintain the telephone line's talking state for a while even if the operator takes the mobile device out of his hand and performs some other operation during a call. Needless to say, 5. In the above embodiment, a mobile device using slide switches as hook switches (only two were explained, but even if these are slide switches, it is a type of mobile device that operates by the weight of the mobile device). It is also obvious that the attachment part of the touch senna can be changed as appropriate depending on the shape of the grip part.

Since the present invention is configured and operates as explained above, it is possible to move to a cordless seven-story system! It is possible to prevent unintended internal battery consumption and continuation of the call state caused by forgetting to turn off the hook switch or misoperation (-), thereby improving the usability of the mobile device and reducing power consumption. 4゜ has a remarkable effect in significantly reducing accidents such as loss of communication due to
