Device for transmitting and receiving information signal in multimedia communication system
First Claim
1. A device for receiving and transmitting information signal in a multimedia communication system including a transceiver unit for transmitting and receiving the information signal to and from the inside of a room, said device comprising:
- a base unit adapted to be mounted to a wall of the room to detachably support said transceiver unit, said base unit having a receptacle electrically connected to an information transmission line routed within the wall;
said transceiver unit comprising circuit means for transmitting and receiving the information signal and a housing with a plug and hooks, said plug being electrically connected to said circuit means and projecting on a plug surface defined on said housing to be detachably connected to said receptacle for establishing a signal communication between said circuit means and said information transmission line, said hooks projecting on said plug surface to detachably engage into corresponding grooves formed in said base unit for supporting said transceiver unit to said base unit;
wherein the present invention is characterized in that;
said base unit comprising a disk member which is provided with sail receptacle and said grooves exposed in a receptacle surface defined on said disk member;
said housing is formed with a circular wall projecting on said plug surface to surround said plug and hooks, and a guide wall projecting on said plug surface inside said circular wall and around said plug;
said disk member has a diameter slightly smaller than an inner diameter of said circular wall so that said disk member can fit within said circular wall when said transceiver unit is attached to said base; and
thatsaid disk member is formed in said receptacle surface with a guide groove of such a configuration that said guide wall is allowed to be inserted into said guide groove only when said guide wall opposes to said guide groove at a particular angular orientation where said plug comes to be connectable with said receptacle.

Abstract
A device used in a multimedia communication system is formed with a transceiver unit for transmitting and receiving information signal to and from the inside of a room and a base unit adapted to be mounted to a wall of the room to detachably support the transceiver unit. The transceiver unit has a plug surface on which a plug projects, a circular wall projecting on the plug surface to surround the plug, and a guide wall projecting on the plug surface inside the circular wall and around the plug. The base unit comprises a disk member which is provided with a receptacle exposed in a receptacle surface defined on the disk member. The disk member has a diameter slightly smaller than an inner diameter of the circular wall so that the disk member can fit within the circular wall when the transceiver unit is attached to the base. The disk member is formed in the receptacle surface with a guide groove of such a configuration that the guide wall is allowed to be inserted into the guide groove only when the guide wall opposes to the guide groove at a particular angular orientation where the plug comes to be connectable with the receptacle. The device can provide a safe and easy working condition for attaching the transceiver unit to the base unit.
