  • Publication number: 20040234305
    Abstract: A sheet nipping mechanism is applied to an image forming apparatus and has a transfer belt for transporting a sheet having a toner image through a photosensitive drum. A fixing roller and a pressure roller are downstream of the transfer belt and are vertically aligned in a paired manner to define a nip zone therebetween for nipping the sheet. A guide is disposed between the nip zone and the downstream end of the transfer belt. The fixing roller has a reverse-crown shape whose diameter is gradually reduced in a direction extending from each of the opposite transverse ends to the central region of the fixing roller. The guide has an edge opposed to the nip zone and is formed in a crown shape conformable to the reverse-crown shape. The sheet nipping mechanism prevents crimples and bouncing of sheet in the nip zone.

  • Patent number: 6650862
    Abstract: Disclosed is an image forming apparatus that enables to transversely move a sheet separator without a dedicated drive source and with a simplified construction to thereby reduce production cost of the apparatus. The image forming apparatus includes a thrust driving mechanism for reciprocating the sheet separator in an axial direction of a heater roller. The mechanism includes a worm gear which is rotated by a driving force of a drive source for rotating the heater roller, a helical gear which is meshed with the worm gear, and an eccentric cam which is mounted coaxially with an axis of rotation of the helical gear. A guide member for supporting the sheet separator is reciprocated in the axial direction of the heater roller in accordance with rotation of the eccentric cam.

  • Patent number: 6538379
    Abstract: A discharge lamp comprises an arc tube 6 made of a translucent ceramic dosed with a metallic halide. The discharge is conducted between electrodes 20 disposed in the arc tube 6. The arc tube 6 comprises a main tube body 11 having a large diameter portion 11A and a small diameter portion 11C, and a narrow tube 12 airtightly fixed to the small diameter portion 11C while penetrating the small diameter portion 11C. In the discharge lamp, supposing that L (mm) is the length of a protrusion from the main tube body of the narrow tube portion 12 and P (W) is the rated power of the discharge lamp, L and P satisfy the relationship (P+268.75)/31.25≦L≦(P+456.25)/31.25 and 200≦P≦450.

  • Publication number: 20020190653
    Abstract: An arc tube 6 of discharge lamp comprises a main tube body 11 of translucent ceramic sealed with a terminal plate 13 at both ends thereof. The main tube body 11 comprises integrally a large diameter portion 11A, a tapered portion 11B which is disposed at both sides of the large diameter portion 11A and has a smaller diameter toward the forward end thereof, and a small diameter portion 11C which is connected to the forward end of the tapered portion 11B. In this arrangement, the discharge lamp can be produced more easily than the conventional structure having a narrow portion integrally formed at both ends of a ceramic tube body, making it possible to drastically reduce cost. Further, since a low temperature zone can be only with difficulty formed inside the arc tube during discharge, the luminous efficiency can be raised.

  • Publication number: 20020185974
    Abstract: The reliability of the airtight sealed section is improved by providing a metallic or ceramic insertion member at a portion positioned between an electricity introducing member and a narrow tube in the airtight sealed section. The difference between the inner diameter of the narrow tube and the outer diameter of the insertion member is made 0.02 to 0.6 mm. The electricity introducing member is constructed by a halogen-resistant first member and a second member whose coefficient of linear expansion is similar to that of the narrow tube, and the junction of the first member and second member is covered with a halogen-resistant glass sealant. The difference between the insertion length of the second member into the narrow tube and the flow-in length of the glass sealant into the narrow tube is made 1 mm or more.

  • Patent number: 5363177
    Abstract: An opening for discharging toner is formed in a lower part of a cartridge body containing toner. A shutter mounting body is mounted on the opening. A first shutter is slidably mounted on the shutter mounting body. A second shutter is slidably mounted on the first shutter. A front end of a sealing member for sealing the opening is extended, the extended front end being inserted through a seal traction opening formed in a front end of the second shutter, and fixed to a front end of the first shutter. When the second shutter is pulled out of the shutter mounting body, the sealing member is towed by the seal traction opening. In addition, the first shutter is further towed by the sealing member, to be also pulled out. Consequently, nearly half of the sealing member from its front end is stripped.

  • Patent number: 5337125
    Abstract: It is a major object of the present invention to break down and level a heap-up of toner built in the hopper through dropping from the cartridge when feeding toner into the hopper and to prevent toner from leakage from the cartridge due to erroneous operation with a remarkably simple and cheap construction. Namely, the leveling member moves a plurality of number of times in line with engaging and disengaging operation of the cartridge for the hopper and opening and closing operation of the cartridge in the same direction of the shutter, thereby causing a heap-up of toner built in the hopper housing of the hopper to be effectively broken down and leveled. Furthermore, only when the shutter is in its closed status for the cartridge, the cartridge can be removed from the opening of the hopper.
