Abstract

Disclosed is a mechanical device in the electro-photographic printer for automatically shielding a flash lamp box not to be touched by operator at its heated surface along with movement of the lamp box for cleaning the surface. A plate swings down accompanied with the swing-up motion of the lamp box and shields it. Once the plate covers the lamp box, the plate is able to swing back manually and restore to the shielding position when released from manual operation while the lamp box remains still. (Image Omitted) Fig. 1 shows an isometric view and Fig. 2 shows a cross-sectional view of the plate moving mechanism. When the lamp box 1 manually swings to the open position A, an actuator lever 2 also swings around lever pin 3.

Swing Mechanical Cover for a Fuser Cover

Disclosed is a mechanical device in the electro-photographic printer for automatically shielding a flash lamp box not to be touched by operator at its heated surface along with movement of the lamp box for cleaning the surface. A plate swings down accompanied with the swing-up motion of the lamp box and shields it. Once the plate covers the lamp box, the plate is able to swing back manually and restore to the shielding position when released from manual operation while the lamp box remains still.

Fig. 1 shows an isometric view and Fig. 2 shows a cross-sectional view of the plate moving mechanism. When the lamp box 1 manually swings to the open position A, an actuator lever 2 also swings around lever pin 3. By this motion, a wire 4, of which one end is fixed to a wire roller 5 and the other is to a pin 6, on the actuator lever 2 rotates the wire roller 5 in direction of B. The rotation of the wire roller 5 causes a shaft 7 to rotate in direction of C via a wire roller pin 8 and a torsion coil spring 9. Therefore, a plate 10 which is fixed to the shaft 7 swings to the position D. During this motion, the wire 11 winds around the shaft 7 decompressing a spring 12. The wire 11 is fixed to the wire roller 5. The wire roller 5 is able to rotate freely around the shaft 7. If the plate 10 is manually swung back, the shaft 7 rotates to the direction of E, causing the torsion coil spring 9 to unwind. When the plate 10...
