PURPOSE:To uniformalize the length of a recording paper required for a signal data frame even if a time distance, for which the data frame is recorded, changes, by constituting a device such that the single data frame is recorded by means of a constantly fixed dot printing number. CONSTITUTION:Through setting of a period TL of a single data frame in a condition setting part 26, a controller 7 computes and decides so that a data writing period TL is brought to TL/Tt=C (constant value) based on the period TL, and a data writing period Tt is automatically set in a data writing period generating part 6. The value of C is the number of dots which is printed in a thermal printer 17 for the single data frame, and is initially set in a condition setting part 26. An analogue wave form, a time display, and a data display are then pictured in the single data frame by means of the value. |
