A driving device includes: a main body; a striking part movably supported by the main body; a handle protruding from the main body; and a nose part attached to the main body and holding a fastener before being hit by the striking part, the nose part movably accommodating the striking part and having an injection path for guiding the fastener and an injection port connecting with the injection path and firing the fastener, an opening extending from the injection port toward the handle being provided on a handle side of the injection path, and a width of the opening being larger than an outer diameter of a head of the fastener in a plan view perpendicular to a linear moving direction of the striking part.

Driving device

A driver capable of suppressing increase in a load torque of a motor when a striking mechanism is moved by the torque of the motor against a force of a first moving mechanism is provided. The driver includes a striking mechanismmovable in a first direction Band a second direction Bopposite to the first direction Band a first moving mechanism configured to move the striking mechanismin the first direction Bto strike a fastener, and the driver further includes a motor, a second moving mechanismrotated by the torque of the motor and configured to move the striking mechanismin the second direction against a force of the first moving mechanism, and torque suppression mechanismsA toH configured to suppress increase in the torque of the motor when the striking mechanismis moved in the second direction B

Driver, striking mechanism, and moving mechanism

A polarizing plate according to an embodiment of the present invention includes a polarizing film having a thickness of 10 &#x3bc;m or less and a protective layer provided on at least one side of the polarizing film through intermediation of an adhesion layer. The adhesion layer has a thickness of 0.7 &#x3bc;m or more, and the adhesion layer has a percentage of bulk water absorption of 10 wt % or less.

Polarizing plate

The present invention provides a polarizer protective film excellent in optical properties (retardation and haze) and excellent in the adhesion property between a polarizer and a polarizer protective film (in particular, under high temperature and high humidity conditions). The polarizer protective film of the present invention includes a (meth)acrylic resin film and an easy-adhesion layer disposed on at least one side of the film. The easy-adhesion layer is formed from an aqueous (meth)acrylic resin dispersion.

Polarizer protective film, polarizing plate, and image display apparatus

A method of producing a polarizing plate according to an embodiment of the present invention includes: stretching and dyeing a laminate including a resin substrate and a polyvinyl alcohol-based resin layer formed on one side of the resin substrate to produce a polarizing film on the resin substrate; laminating a first protective film on the polarizing film on an opposite side to the resin substrate; and peeling the resin substrate, followed by laminating a second protective film on the polarizing film on a side from which the resin substrate has been peeled. The laminating of at least one of the first protective film and the second protective film is performed through an adhesive having a moisture content of 10% or less.

Polarizing plate and method of producing polarizing plate

The present invention provides a polarizer protective film capable of suppressing blocking that occurs in taking up the film. The polarizer protective film of the present invention includes a (meth)acrylic resin film and an easy-adhesion layer formed of an easy-adhesive composition including a urethane resin and fine particles. The fine particles include preferably colloidal silica.
