  • Patent number: 6807888
    Abstract: There is provided a recording material cutting device having a mechanism for cutting a recording material by the whole edge of a cutter blade so as to prolong the service life of the cutter blade, while allowing to simplify the structure of the device, to downsize the device, and to improve the straightness of the cut portion of the recording material. Upon starting the cutting, the cutting-in depth of the cutter blade 130 is the deepest, and the recording material 113 is cut by the near-root portion of the cutter blade 130. As the whole of the cutter unit 112 moves in the direction C while the seizing member 123 abuts onto the cammed surface of the cammed portion 132, the cutter holder 122 is gradually lifted up so that the cutting-in depth of the cutter blade 130 into the recording material 113 is gradually shallowed.

  • Patent number: 6721060
    Abstract: A recording medium cutter capable of moving between two positions, a cutting position and a non-cutting position, in a short time, and also capable of cutting a recording medium at accurate positions. A main body (40) rotatably holding a rotary blade (32) and a driven blade (34) is located between side plates (36 and 38) of the cutter (30). A main shaft (39) serving as the center shaft of the rotary blade (32) is rotatably secured to the side plates (36 and 38). The main shaft (39) also serves as the rotating shaft of the main body (40). A driving motor is secured to the mounting plate (42) of the side plate (36). When the main shaft (39) is rotated by the driving motor (44), the rotary blade (32) rotates. Because the driven blade (34) is pressed against the side face of the rotary blade (32), as the rotary blade (32) rotates, the driven blade (34) revolves around the main shaft (39). As a result, the main body (40) also rotates around the main shaft (39).

  • Patent number: 6478491
    Abstract: An image forming apparatus having a print member for forming an image on a recording sheet while reciprocating in a predetermined direction includes a pair of conveyance rollers and a separating member for separating the of conveyance rollers from one another. A control lever for controlling the separating member is provided as is a changeover element for permitting the control lever to rotate when said print member moves in a predetermined direction and is not located at an interference area in which the print member would collide with the conveyance rollers if they were separated, and for prohibiting the control lever from rotating when the print member is located at the interference area.

  • Patent number: 6273624
    Abstract: A cam 37 is rotated in an arrow F direction. This causes sheet conveyance rollers 10a, 10b and guide elements 33, 34 to rotate on a lower conveyance shaft 27 and an upper conveyance shaft 30, respectively, so that they are separated from a drive roller 12. Thus, a spur plate 21 faces the upward stream end with respect to the recording sheet conveyance direction and opens in synchronism with the sheet conveyance rollers 10a and 10b, etc. Accordingly, it is possible to readily remove a recording sheet subjected to the jam.
