ABSTRACT:
The present invention relates to a recording mechanism of a picture and writing transmission and recording system using a ball-point-pen which is pressed to a recording surface with some pressure corresponding to electrical signals obtained from informations of letters, marks and pictures so as to put ink on the surface. The present invention is characterized in that a moving coil, which is connected with the said ball-point-pen and is set in magnetic field so as to be controlled with signal current, is freely movable in the axial direction of the ball-point-pen in a certain range so that the pressure of the ball-point-pen which is given to the recording surface and corresponding to a determined signal current is kept essentially uniform.
