Abstract
Abstract A charging unit for charging a power source incorporated in a portable radio apparatus or similar apparatus. The unit includes a tray which is movable between a mounting position and a connecting position while carrying the apparatus thereon. When the apparatus is attached to and detached from the charging unit, it is substantially free from disfigurement including scratches since only the tray is moved.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
165 words
A charging unit for charging a power source incorporated in a portable radio apparatus, comprising: a body having a base plate; a tray for supporting the apparatus, said tray being slidably disposed on said base plate; a charging section attached to said body, said tray being slidable on said base plate between a mounting position wherein the apparatus can be mounted on said tray, and a connecting position wherein an apparatus mounted on said tray is engaged only with said charging section and said tray for charging said power source, said charging section including a signal connector and an antenna connector, wherein when the tray is in said connecting position the apparatus is engaged only with the charging section and said tray so as to protect the apparatus from damage due to contact with other parts of the charging unit, and terminals of the apparatus mate with said signal and antenna connectors; and a locking section for releasably locking said tray in said connecting position.
Claim 2
Dependent Claim
165 words
A charging unit for charging a power source incorporated in a portable radio apparatus, comprising: a body having a base plate; a tray for supporting the apparatus, said tray being slidably disposed on said base plate; a charging section attached to said body, said tray being slidable on said base plate between a mounting position wherein the apparatus can be mounted on said tray, and a connecting position wherein an apparatus mounted on said tray is engaged only with said charging section and said tray for charging said power source, said charging section including a signal connector and an antenna connector, wherein when the tray is in said connecting position the apparatus is engaged only with the charging section and said tray so as to protect the apparatus from damage due to contact with other parts of the charging unit, and terminals of the apparatus mate with said signal and antenna connectors; and a locking section for releasably locking said tray in said connecting position.
Claim 3
Dependent Claim
20 words
A charging unit as claimed in claim 1, further comprising biasing means for biasing said tray toward said mounting position.
Claim 4
Dependent Claim
52 words

Claim 5
Dependent Claim
187 words
A charging unit for charging a power source incorporated in an apparatus, comprising: a body having a base plate; a tray for supporting the apparatus, said tray being slidably disposed on said base plate, said tray including a pin for being connected to a terminal of the apparatus; a charging section attached to said body and including a signal connector and an antenna connector, said tray being slidable on said base plate between a mounting position wherein the apparatus can be mounted on said tray and a connecting position wherein an apparatus mounted on said tray is engaged only with said charging section and said tray for charging said power source, wherein when the tray is in said connecting position the apparatus is engaged only with the charging section and said tray so as to protect the apparatus from damage due to contact with other parts of the charging unit, and terminals of the apparatus engage with the signal and antenna connectors in said charging section; means for biasing said tray toward said mounting position; and locking means for releasably locking said tray in said connecting position.
Claim 6
Dependent Claim
187 words
A charging unit for charging a power source incorporated in an apparatus, comprising: a body having a base plate; a tray for supporting the apparatus, said tray being slidably disposed on said base plate, said tray including a pin for being connected to a terminal of the apparatus; a charging section attached to said body and including a signal connector and an antenna connector, said tray being slidable on said base plate between a mounting position wherein the apparatus can be mounted on said tray and a connecting position wherein an apparatus mounted on said tray is engaged only with said charging section and said tray for charging said power source, wherein when the tray is in said connecting position the apparatus is engaged only with the charging section and said tray so as to protect the apparatus from damage due to contact with other parts of the charging unit, and terminals of the apparatus engage with the signal and antenna connectors in said charging section; means for biasing said tray toward said mounting position; and locking means for releasably locking said tray in said connecting position.
Claim 7
Dependent Claim
33 words
