Abstract

PURPOSE:To move a pen tray without allowing ink to flow out and to lock a recording pen by manually allowing said pen to jump up without obstructing automatic operation, by moving the recording pen up and down by a cam plate and locking the movement thereof by a pen locking plate and moving the pen tray in a horizontal direction by a drive means. CONSTITUTION:At the time of recording, pen raising arms 51, 52 are allowed to fall by the cam plate 49 rotated by a stepping motor 43 and a recording pen 24 is allowed to fall through a pen raising rod 53 and the leading end thereof is brought into contact with recording paper 25 to record a waveform to be measured. At this time, the first gear 38 meshing with the gear 42 integrally fixed to the cam plate 49 is rotated and the pen tray 36 provided to a pen tray slide plate 28 is separated from the part directly under the leading end of the pen 24. At the time of non-recording, the arms 51, 52 are raised and the leading end of the pen 24 is separated from the recording paper 25 and a pen locking plate 57 is pushed by the cam plate 49 to release the locking of the arms 51, 52. Next, the slide plate 28 moves by the gear 38 and the pen tray 36 is positioned directly under the leading end of the pen 24 and the pen 24 is allowed to fall to be brought into contact with the pen tray 36.
