Abstract

A radio telephone apparatus for transmitting and receiving information signals as electrical waves includes a main body section towards one end of which a speaker unit is enclosed. A battery casing accommodating a battery which is adapted for supplying power to the main body section is detachably mounted on the other end of the main body section to reduce the size and the thickness of the apparatus. A ringer device is enclosed within the battery casing so that the acoustic sound emitted by the ringer is prevented from reaching the user'"'"'s ear which is in the vicinity of the speaker unit. The microphone for the radiotelephone apparatus in also enclosed within the battery casing.

Claims

1. A radio telephone apparatus, comprising:

a receiver section, a transmitter section, a speaker unit, and a microphone unit;

a first casing accommodating at least said receiver and transmitter sections and said speaker unit, said speaker unit being positioned adjacent one end of said first casing;

a second casing accommodating a battery supplying a driving current to said receiver section and said transmitter section, said second casing having a releasable attachment means for attachment of the second casing to said first casing at another end thereof opposite said one end;

said microphone unit being mounted in said second casing;

a ringer device being also provided in said second casing

said microphone unit being mounted on a front wall of said second casing and said ringer device being mounted on a back wall of said second casing; and

said second casing including a microphone container accommodating said microphone unit, said container being pivotably connected to a portion of said second casing, said microphone container having open and closed positions, said microphone unit being operable in either said open or closed positions, and in said open position said microphone unit being spaced at a greater distance from said speaker unit than in said closed position.

2. A radio telephone apparatus, comprising:

a receiver section, a transmitter section, a speaker unit, and a microphone unit;

a first casing accommodating at least said receiver and transmitter sections and said speaker unit, said speaker unit being positioned adjacent one end of said first casing;

a second casing accommodating a battery supplying a driving current to said receiver section and said transmitter section, said second casing having a releasable attachment means for attachment of the second casing to said first casing at another end thereof opposite said one end;

said microphone unit being mounted in said second casing; and

said second casing including a microphone container accommodating said microphone unit, said container being pivotably connected to a portion of said second casing, said microphone container having open and closed positions, said microphone unit being operable in either said open or closed positions, and in said open position said microphone unit being spaced at a greater distance from said speaker unit than in said closed position.

3. A radio telephone apparatus, comprising:

a receiver section, a transmitter section, a speaker unit, and a microphone unit;

a first casing accommodating at least said receiver and transmitter sections and said speaker unit, said speaker unit being positioned adjacent one end of said first casing;

a second casing accommodating a battery supplying a driving current to said receiver section and said transmitter section, said second casing having a releasable attachment means for attachment of the second casing to said first casing at another end thereof opposite said one end;

said microphone unit being mounted in said second casing; and

said releasable attachment means comprising means for allowing the second casing to be slid laterally relative to said other end of said first casing for attachment thereto, said releasable attachment means having associated therewith a cover member means for protecting an electrical contact means for connecting said battery to said receiver and transmitter sections, and means being provided on said first casing for pushing said cover means away from said contact means when said second casing is laterally slid into position for connection with said first casing.

4. A radio telephone apparatus, comprising:

a first casing containing a transmitter section and a receiver section, said first casing having adjacent one end thereof a speaker unit, and at an opposite end thereof a stationary contact protruding therefrom;

a second casing mateable with said first casing and comprising a battery container having a spring contact at a first end thereof contactable with said stationary contact of said first casing;

said second casing having means for slidable attachment of said first end of said second casing to said other end of said first casing;

a contact cover means provided at said first end of said second casing for sliding between a position overlying said spring contact and a position where said spring contact is uncovered for connection to said stationary contact;

biasing means for resiliently biasing said contact cover means to said overlying position; and

an abutting member means at said other end of said first casing for abutting against said cover member means for sliding the same to said uncovered position when said second casing is slid into connection with said first casing.

5. An apparatus according to claim 4 wherein the abutting member comprises said stationary contact protruding at said other end of said first casing.

6. An apparatus according to claim 4 wherein a microphone unit is provided in said second casing and exposed through transmission apertures in a front wall of said second casing to the outside.

7. An apparatus according to claim 4 wherein said second casing comprises a microphone container means for accommodating said microphone unit, said container means being pivotable between an opened and closed position wherein said microphone unit is spaced in said open position a greater distance from said speaker unit than in said closed position.
