Abstract
Abstract A transceiver having transmitting, receiving, and standby modes of operation includes in a first embodiment, a first push button actuable for selectively establishing the receiving and transmitting modes and a rotatable element positionable to select the standby or receiving modes or the inoperative state of the transceiver. An interlocking mechanism interconnects the first push button with the rotatable element. In another embodiment, a second push button, rather than the rotatable element, is depressible for establishing the standby mode. In each case, the transceiver can be changed over from the standby to the transmitting or receiving mode by depressing the first push-button, or by depressing and then releasing the first push button, respectively.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
99 words
In a transceiver having transmitting, receiving, and standby modes of operation; an apparatus for selectively establishing said modes of operation including means actuable to establish said standby mode of operation, changeover means and interconnecting means for interconnecting said means actuable to establish said standby mode of operation with said changeover means, wherein said change-over means is effective, when depressed, to cause said interconnecting means to change said transceiver from said standby mode to said transmitting mode or, when depressed and then released, to cause said interconnecting means to change said transceiver from said standby mode to said receiving mode.
Claim 2
Dependent Claim
99 words
In a transceiver having transmitting, receiving, and standby modes of operation; an apparatus for selectively establishing said modes of operation including means actuable to establish said standby mode of operation, changeover means and interconnecting means for interconnecting said means actuable to establish said standby mode of operation with said changeover means, wherein said change-over means is effective, when depressed, to cause said interconnecting means to change said transceiver from said standby mode to said transmitting mode or, when depressed and then released, to cause said interconnecting means to change said transceiver from said standby mode to said receiving mode.
Claim 3
Dependent Claim
30 words
A transceiver as in claim 1; wherein said interconnecting means comprises interlocking means for mechanically interlocking said means actuable to establish said standby mode of operation with said change-over means.
Claim 4
Dependent Claim
54 words
A transceiver as in claim 2; wherein said means actuable to establish said standby mode of operation includes first manually displaceable mode-determining control means having a first position corresponding to said standby mode, a second position for said transmitting and receiving modes, and a third position corresponding to an inoperative state of said transceiver.
Claim 5
Dependent Claim
25 words
A transceiver as in claim 3; wherein said first manually displaceable mode-determining means is rotatable to each of said first, second and third positions thereof.
Claim 6
Dependent Claim
68 words
A transceiver as in claim 4; wherein said interlocking means includes a first interlocking member, means for rotatably coupling said first interlocking member with said first manually displaceable mode-determining means, and a second interlocking member responsive to depression of said change-over means in said standby mode to causes said first interlocking member to rotate said first manually displaceable mode-determining means from said first position to said second position.
Claim 7
Dependent Claim
28 words
A transceiver as in claim 4; wherein said first manually displaceable mode-determining means includes a lever pivotally mounted at an exterior surface of a housing of said transceiver.
Claim 8
Dependent Claim
63 words
A transceiver as in claim 6; further comprising an antenna movably mounted on said housing for movement between a stored position against said surface and a projecting operative position, said antenna acting on said lever in response to movement from said operative position to said stored position for disposing said first manually displaceable mode-determining means in said position corresponding to the inoperative state.
Claim 9
Dependent Claim
31 words
A transceiver as in claim 7; wherein said antenna prevents manual operation of said lever when said antenna is disposed in said stored position against said surface of the transceiver housing.
Claim 10
Dependent Claim
58 words
A transceiver as in claim 2; wherein said means actuable to establish said standby mode include second manually displaceable mode-determining means which is depressible for said standby mode, and third manually displaceable mode-determining means having a first position for establishment of said transmitting and receiving modes and a second position corresponding to an inoperative state of said transceiver.
Claim 11
Dependent Claim
56 words
A transceiver as in claim 9; wherein said interlocking means includes a latch member operative to hold said second manually displaceable mode-determining means in a depressed position, and means responsive to depression of said change-over means for releasing said latch member and thereby permitting return of said second manually disposeable mode-determining means from said depressed position.
Claim 12
Dependent Claim
21 words
A transceiver as in claim 9; wherein said third manually displaceable mode-determining means is rotatable to each of said positions thereof.
Claim 13
Dependent Claim
28 words
A transceiver as in claim 11; wherein said third manually displaceable mode-determining means includes a lever pivotally mounted at an exterior surface of a housing of said transceiver.
Claim 14
Dependent Claim
54 words
A transceiver as in claim 12; further comprising an antenna which is movably mounted on said housing for movement between a stored position against said surface and an extended operative position, said antenna acting on said lever in response to movement from said operative position to said stored position for establishing said inoperative state.
Claim 15
Dependent Claim
24 words
A transceiver as in claim 13; wherein said antenna prevents manual operation of said lever when said antenna is disposed in said stored position.
Claim 16
Dependent Claim
54 words
A transceiver as in claim 2; wherein said means actuable to establish the standby mode is also positionable for establishing an inoperative state; and further comprising means for maintaining said change-over means in a depressed state in response to said means actuable to establish said standby mode being positioned for establishing said inoperative state.
Claim 17
Dependent Claim
15 words
A transceiver as in claim 1; wherein said change-over means includes a manually actuable push-button.
