Title: Method and apparatus for forming picture
Inventor: SAKANO YUKIO
IPC: H04N1/29
Filed: 1990-04-26
Abstract: PURPOSE:To suppress the occurrence of void at a tail end by writing a ghost latent image to a non-picture area in succession to the vicinity of the tail end of a picture area to be written in the subscanning direction. CONSTITUTION:A ghost latent image 24 not in an original picture is written over a width V of a non-picture area (white picture area) in succession to the vicinity of a tail end of a latent image 23 in the subscanning direction (y). When the ghost latent image 24 is developed, it appears on the picture thin or does not appear at all and it is a latent image corresponding to a thin picture discriminated to be a white picture by eyes. Since the latent image 24 is not a border directly to a white picture even in the vicinity of the latent image 23, an excellent half tone picture 25 in which occurrence of voice is reduced is reproduced.

Abstract: PURPOSE:To prevent wasteful ringing and to properly inform of the occurrence of abnormality by detecting whether an incoming call is a telephone or facsimile when the incoming call is received, ringing a telephone device using a pseudo- calling signal when the abnormality including the run-out of recording paper and the jamming of them, etc., is detected, and changing the ringing sound between the call incoming time and the abnormality occurrence time. CONSTITUTION:When the calling signal is detected by a calling signal detection circuit 2, a CML6 is switched to the facsimile equipment side, the signal is detected by means of the tone detection function of a MODEM 10, and when the signal is detected, facsimile communication is executed. When the signal is not detected, it is judged that the incoming call is telephone and the calling signal is outputted to a slave telephone 8. When the slave telephone 8 is hooked off, the calling from a pseudo-calling signal generation circuit 1 is ended, the CML6 is switched to the telephone device side and the communication is executed. When it is not hooked off, it is judged that an operator is absent and the line is released. When the slave telephone 8 is hooked off, the transmission of the calling signal from the pseudo-calling signal generation circuit 1 is ended and warning sound is outputted by a audible signal generation circuit 16.
