Claim 1
Independent Claim
213 words
A telephone having a plurality of standard dialing push buttons arranged on an operation panel on a body of the telephone for entering telephone numbers, the telephone body being internally provided with a memory for prestoring therein at least one telephone number of at least one subscriber to be called and with a dial signal circuit for retrieving telephone number data from the memory in response to an input signal for placing a call to a desired subscriber and transmitting the data to telephone lines upon conversion to dial signals, the telephone comprising: a closure for removably covering the surface of the operation panel on the telephone body; at least one automatic dialing push button respectively arranged on the surface of the closure, wherein data representing at least one telephone number is storable in the memory in corresponding relation to the automatic dialing push button, and wherein the telephone body includes means for detecting depression of the automatic dialing push button with the covering of the telephone panel with the closure in a closed state and feeding a detection signal to the dial signal circuit for the circuit to transmit to the telephone lines the telephone number data corresponding to the depressed automatic dialing push button and in the form of dial signals.

A telephone having a plurality of standard dialing push buttons arranged on an operation panel on a body of the telephone for entering telephone numbers, the telephone body being internally provided with a memory for prestoring therein at least one telephone number of at least one subscriber to be called and with a dial signal circuit for retrieving telephone number data from the memory in response to an input signal for placing a call to a desired subscriber and transmitting the data to telephone lines upon conversion to dial signals, the telephone comprising: a closure for removably covering the surface of the operation panel on the telephone body; at least one automatic dialing push button respectively arranged on the surface of the closure, wherein data representing at least one telephone number is storable in the memory in corresponding relation to the automatic dialing push button, and wherein the telephone body includes means for detecting depression of the automatic dialing push button with the covering of the telephone panel with the closure in a closed state and feeding a detection signal to the dial signal circuit for the circuit to transmit to the telephone lines the telephone number data corresponding to the depressed automatic dialing push button and in the form of dial signals.
Claim 3
Dependent Claim
136 words
A telephone as defined in claim 1, wherein the detecting means includes at least one specified button among the standard dialing push buttons on the operation panel on the telephone body, and a mode change key provided on the operation panel for setting an automatic dialing mode whereby the automatic dialing push button becomes operable, the closure having a projection for depressing the mode change key when the closure is closed relative to the telephone body, the specified standard dialing push button respectively corresponding to the automatic dialing push button so that when the automatic dialing push button is manipulated with the closure covering the telephone body, the manipulated automatic dialing push button depresses the standard dialing push button corresponding thereto to retrieve the stored telephone number data corresponding to the depressed standard dialing push button.
Claim 4
Dependent Claim
