Abstract

PURPOSE:To make it possible to use a radiotelephone even if it is separated from the car, by constituting the mobile radio unit so that a part of it can be fitted and removed and by constituting a portable radiotelephone unit which is operated by the battery provided in the part above when the part above is removed from the car. CONSTITUTION:Part 16 surrounded with the dotted line except antenna 1, transmission and receiving part 2 and transmission wave amplifying part 7 is so constituted that part 16 can be fitted and removed. In case that part 16 is removed from the car, a portable radiotelephone unit is constituted which is operated by the battery provided in part 16. As a result, the land mobile radiotelephone can be used not only in the car but also in the place separated from the car.
