    摘要: A printing hammer driving apparatus for high-speed printers comprises a lever member acting as a hammer operating part, an armature forming a part of a magnetic circuit, and an electromagnet forming, together with the armature, the magnetic circuit. The lever member has a rotational supporting point at the base end thereof and is made of a light-weight non-magnetic material. The armature is projected in one of the rotational directions of the lever member from the intermediate part of the lever member. The electromagnet has at least one core and an exciting coil wound on the core. A core has a magnetic pole face perpendicular to the direction of attraction of the armature and a magnetic pole face parallel to the direction of attraction of the armature. The magnetic pole face perpendicular to the direction of armature attraction is opposed with a gap to the forward end face of the armature, and the magnetic pole face parallel to the direction of armature attraction is opposed with a gap to the surface of the armatures parallel to the direction of attraction thereof.

    摘要: A printing head is disclosed in which each attraction member is driven by a magnetic attraction and an impact printing operation is carried out by a strain energy caused by a displacement of a spring member provided on the attraction member. The fulcrum of rotation of the attraction member is defined between the attraction member and a magnetic polar face of a yoke constituting a magnetic circuit together with the attraction member. Means for adjusting the resilient force of the spring member is engaged with a free end of the spring member.

    摘要: There is provided a PLO device which performs high-accuracy, high-quality clock recovery. A shifted data generation part generates shifted data, and a first phase comparison part outputs first difference data. A first filter removes an alternating-current component from the first difference data and outputs a first detection voltage. A delay part delays input data for a time corresponding to half of one time slot with the use of an analog delay element and outputs delayed data. A second phase comparison part compares the phases of the input data and delayed data with each other and outputs second difference data. A second filter removes an alternating-current component from the second difference data and outputs a second detection voltage. An arithmetic section divides the first detection voltage by the second detection voltage to obtain a control voltage. A clock oscillation section outputs recovered clock based on the control voltage.

    摘要: An image forming apparatus has an endless belt which serves as an image carrier is characterized by reduced image misregistration and reduced machining cost. When the endless belt feed path is divided into a path from a drive roller to a tension roller, and a path from the tension roller to the drive roller, the eccentricity of an idle roller located on the path on the side including a latent image forming point is set to a value smaller than that of an idle roller located on the path not including the image forming point.

    摘要: In an image forming apparatus, attachment/detachment guide pins (10 and 11) are disposed on a side face of a belt cartridge (12). Attachment/detachment guide grooves (30, 31, and 32) which guide the attachment/detachment guide pins (10 and 11) are disposed in a frame (29) of a main unit of an image forming apparatus. A belt tension applying mechanism including a tension link (13) and a spring (15) is disposed on the side of the apparatus main unit. When the belt cartridge (12) is to be attached to the apparatus main unit, the cartridge is attached along the attachment/detachment guide grooves (30, 31, and 32), so that the rotation shaft of a tension roller (4) is easily and surely engaged with the belt tension applying mechanism (13 and 15).
