PURPOSE:To attain to miniaturize the titled apparatus and to enhance the storing property and recording capacity thereof, by forming a felt pen container and its holder into a flat shape while providing a rotary fulcrum to the holder at a position behind the gravity center of a felt pen. CONSTITUTION:The container 20 of each of felt pens 1a-1d and its holder 14 are formed into a flat shape and the attachments slits 26 of the container 20 is inserted, until the protruded parts 28 each provided to a part of each attachment slit 26 are coincided with the recessed parts provided to the movable arms 30 of the holder 14, to fix both of them. Further, a rotary shaft 36, which is fixed to the movable arms 30 at one end thereof and has a sharp leading end, is inserted into the shaft holes 46 provided to both leading end parts of a U-shaped arm 16 at a position slightly behind the gravity center of each of the felt pens 1a- 1d to make it possible to rotate the movable arms 30 around the rotary shaft 36 forward and back. Therefore, a part of the own weight. of each felt pen is added as pen pressure to lighten the pen pressure thereof. By this constitution, the apparatus is miniaturized and the storing property and recording capacity thereof are enhanced. |
