20090277744 | LOCKING DEVICE OF ROTARY SHAFT - A locking device of a rotary shaft includes a clutch member rotating integrally with the rotary shaft and provided so as to be displaceable in the direction of axis of the rotary shaft, a locking member provided in a fixed state to engage the clutch member to regulate the rotation of the clutch member, a biasing member biasing the clutch member toward the locking member, and a torque transmission member rotating under the rotary torque transmitted thereto from a power source, having a boss loosely inserted into a cam groove provided in an outer peripheral portion of the clutch member, and transmitting the rotary torque to the clutch member via the boss. The boss is displaced within the cam groove with switching of the rotation/stop of the torque transmission member or switching of the rotational direction thereof. | 11-12-2009 |
20090279933 | ROTARY SHAFT LOCKING DEVICE AND RECORDING APPARATUS HAVING THE SAME - A rotary shaft locking device includes a locking unit having a transmission gear receiving rotary torque from a power source, transmitting rotary torque to a rotary shaft as the transmission gear receives rotary torque from the power source, and locking the rotary shaft as transmission of rotary torque from the power source is cut off, and a first planetary gear and a second planetary gear provided to be meshed with a sun gear and to planetarily move around the sun gear, and displaced between a meshed position and an unmeshed position so as to be meshed with and separated from the transmission gear. The locking unit locks the rotary shaft for a power cutoff time which occurs when the rotation direction of the sun gear is switched and for which the transmission gear is not meshed with both the first planetary gear and the second planetary gear. | 11-12-2009 |
20130229456 | LIQUID EJECTING APPARATUS - A liquid ejecting apparatus includes a carriage that reciprocates and includes a recording head that ejects liquid and a liquid container that supplies the liquid to the recording head and an optical sensor that includes a light emitting section capable of emitting light toward the carriage and a light receiving section that receives reflected light that is light that has been emitted from the light emitting section and has been reflected by the liquid container. The carriage is provided with a projecting section capable of suppressing incidence of ambient light to the light receiving section of the optical sensor. | 09-05-2013 |
