  • Patent number: 9134500
    Abstract: An object is to realize further size reduction in a lens barrel in which a barrel unit is rotatable in three axis directions. The lens barrel includes a support portion for supporting the barrel unit, a part of the support portion being fixed to an external member, an actuator including a drive base movable in a direction parallel to a surface passing through an optical axis of the barrel unit, and a universal joint mechanism portion for linking the barrel unit and the drive base of the actuator. The support portion supports the barrel unit rotatably about a pitch axis, a roll axis, and a yaw axis with respect to the optical axis direction, and the actuator drives the barrel unit about the pitch axis, the roll axis, and the yaw axis by moving the drive base.

  • Patent number: 6252683
    Abstract: A video printing apparatus feeds sheets of printing media from the lower front portion of the apparatus housing and ejects the print media at the upper front portion of the apparatus housing. The apparatus comprises a feed tray to be loaded with printing media, a feeding unit to feed the printing media into the inside of the apparatus, a transport unit to transport the printing media fed by the feeding unit, a switching unit provided between the feeding unit and the transport unit to switch over the transport route of the printing media, at least one detecting unit provided between the switching unit and the transport unit to detect the printing media, a printing unit to transfer printing onto the printing media, an ejection unit to eject the printing media after they have been printed by the printing unit, and an ejection tray to store the printing media ejected by the ejection unit.

  • Patent number: 5839838
    Abstract: An image printer comprising: a printing member for printing dye on a recording medium; a dye medium take-up member for taking up a dye medium to which the dye is applied; a first power transmission member for transmitting power to the dye medium take-up member; a recording medium transporting member for transporting the recording medium; a drive member for driving the dye medium take-up member and the recording medium transporting member, which can be driven forwardly and reversely; a pivotal member which is pivotal in response to rotation of the recording medium transporting member; a second power transmission member for transmitting power from the recording medium transporting member to the first power transmission member, which is mounted on the pivotal member; an urging member for bringing the recording medium transporting member into contact with the pivotal member so as to transmit driving force of the recording medium transporting member to the pivotal member; and a preventive member for selectively pr
