Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
123 words
A facsimile apparatus comprising: memory means for storing a time and a dial number; sending means for sending a dial signal to a telephone line, the dial signal being either a pulse type and a tone type; ringing means for ringing an attached telephone set; and control means for controlling said sending means so as to send a dial signal according to the dial number stored in said memory means to the telephone line at a first timing according to the time stored in said memory means and the type of the dial signal, wherein said control means controls said ringing means so as to ring the attached telephone set at a second timing according to the time stored in said memory means.
Claim 2
Dependent Claim
123 words
A facsimile apparatus comprising: memory means for storing a time and a dial number; sending means for sending a dial signal to a telephone line, the dial signal being either a pulse type and a tone type; ringing means for ringing an attached telephone set; and control means for controlling said sending means so as to send a dial signal according to the dial number stored in said memory means to the telephone line at a first timing according to the time stored in said memory means and the type of the dial signal, wherein said control means controls said ringing means so as to ring the attached telephone set at a second timing according to the time stored in said memory means.
Claim 3
Dependent Claim
33 words
