PURPOSE:To reduce the material cost and assembling man-hours and to improve the reliability by providing a driving body moving horizontally a supporting board and realizing attaching and detaching of a cartridge with a mechanism convering this horizontal movement into the vertical movement of a holder so as to reduce number of components. CONSTITUTION:When the cartridge 56 is inserted to the holder 47, the tip of the cartridge is contacted with a pin 42. and as the insertion is progressed, a trigger lever 41 is turned clockwise around a round hole 46. A spring 45 is elongated together with this turning, and when a roller 43 passes through a bend part of an L-shaped hole 33, a driving body 32 is moved horizontally in the direction of a panel 53. In pressing a button 54, the trigger lever 41 is turned counterclockwise by the force of the spring 45, the roller 43 is moved up to the right side plate 32b of the L-shaped hole 33. The driving body 32 is parted from the panel 53 again and the holder 47 is floated upward from a support base 26. The cartridge 56 is pushed back by the pin 42 of the trigger lever 41 and a part of it is jumped out of the panel 53. |
