Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cordless telephone device suitable for use in general homes and the like.

[Conventional technology]

This type of cordless telephone device replaces the curl cord (handset/receiver cord) on regular telephones with a wireless one, allowing the telephone to be freely carried around and used within the home. It consists of a handset (phone body) and a handset (transceiver) that is connected to the base phone so that it can transmit and receive electromagnetic waves.

By the way, in this type of cordless telephone device, if there is a power outage in the commercial power supply on the base unit side or if the voltage of the battery power supply on the slave unit side drops, wireless communication becomes impossible. Additionally, if other wireless devices are used in the same area, electromagnetic waves may be interfered with and interference may occur.In such emergencies, connect the base unit and handset using a wired communication cord. It was configured so that wired calls could be made. That is, conventionally, in this type of cordless telephone device, a modular jack is provided for the base unit and the slave unit, and the base unit and the slave unit are connected using a wired telephone cord having a plug that is inserted into these jacks. By doing so, it was possible to switch from a wireless communication system to a wired communication system.

[Problem that the invention attempts to solve]

However, in the structure described above in which the communication method is switched from wireless to wired by attaching and detaching the wired communication cord, a relay, etc. is required to electrically switch the contacts that connect and disconnect the wireless communication circuit. This not only increases manufacturing costs, but also requires space to accommodate these electrical components, leading to problems such as the overall size of the device. This means that the relay mentioned above has contacts,
This is obvious from the fact that it is made up of a complex combination of many parts such as contact springs and electromagnets, making it relatively large and expensive.

For this reason, in the above-mentioned cordless telephone device, a wired/wireless switch for selectively switching between wireless communication and wired communication, and a wired/wireless switch for selectively switching between wireless communication and wired communication, and a wired/wireless switch are provided on the base unit and the handset, respectively, and these switches are connected to the above-mentioned connection and removal of the wired communication cord. A configuration in which the switch can be manually operated from the outside has also been considered, but such a configuration would require a manual operator to switch the wireless/wired switch, increasing the number of component parts and increasing costs. It was something that would have made me very nervous. Furthermore, with such a configuration, it is necessary to switch the wireless/wired switch mentioned above at the same time as connecting the wired call cord, which makes it easy to forget to operate this switch, and also poses problems in terms of operability. Therefore, it is necessary to take these points into consideration and take some measures to further alleviate the above-mentioned problems.

[Means for solving problems]

In order to meet such demands, the cordless telephone device according to the present invention has a wireless/wired switching switch formed on the base unit to switch between wireless calls and wired calls on the base unit. The switch is configured to be switched in conjunction with the opening/closing operation of the opening/closing lid of the code storage.

[Effect]

According to the present invention, a wireless communication state is maintained by closing the storage box in which the wired phone cord is stored with an opening/closing lid, and the storage can be opened and closed in order to use the wired phone cord. By opening the lid, the wireless/wired switch on the base unit side is switched to the wired side, allowing wired calls.
