  • Facsimile apparatus with automatic answering telephone function, and communication method in said apparatus
    Patent number: 5974123
    Abstract: Disclosed is a facsimile apparatus equipped with an automatic answering telephone function, as well as a communication method in this apparatus. When a tone signal from a line is detected after the start of storage of a voice message in response to an incoming call, the voice message presently being recorded is not counted as a received message and a voice message received next is stored in the area in which storage has just been performed. Further, when a DTFM signal, which is a control signal of the automatic answering telephone, is detected, a transition is made to facsimile communication in response to a CNG signal. Thus, erroneous operation in facsimile communication due to a CNG signal recorded in the automatic answering telephone is prevented.

  • Ink jet apparatus and method for detecting ink nondischarge based on ink temperature
    Patent number: 5508722
    Abstract: If one page of recording is terminated, a carriage moves to a position at which a recording head is located opposite a cap. Then, the ink is discharged through nozzles of the recording head onto temperature detecting element within the cap. Temperature change of the temperature detecting element upon contact with the ink is output from a detecting circuit, and the normal discharge of ink is detected by discharge detecting means. In this way, a decrease in the ink remaining or the detection of ink nondischarge can be securely made.
