Abstract:
The present invention provides an inexpensive and compact printing apparatus. The printing apparatus includes a sheet feeding mechanism configured to convey a sheet in an orthogonal direction to a loading direction of a cassette, and moves between a press-contacting position and a retraction position, an urging member configured to urge the cassette in a drawing-out direction, a locking member configured to abut against the cassette at a locking position opposed to the urging member, to regulate a movement of the cassette, and to enable draw-out of the cassette at a release position, and an interlocking member configured to regulate the movement of the locking member when the sheet feeding mechanism is located at the press-contacting position, and to release the regulation of the movement of the locking member when the sheet feeding mechanism is located at the retraction position.
Abstract:
A table saw in one embodiment a swing arm movable along a swing arm path between a first swing arm position adjacent a latch hold mechanism and a second swing arm position spaced apart from the latch hold mechanism, a blade supported by the swing arm, a charge coupling plate mounted in close proximity to the blade so as to form a capacitor, an actuating device configured to transfer a force to the swing arm when the swing arm is maintained at the first swing arm position resulting in a bias on the latch hold mechanism, and a control system configured to control the actuating device to transfer the force to the swing arm in response to a sensed change in capacitance of the capacitor.
Abstract:
A saw assembly includes a housing, a drive member, a motor, a switch, a trigger, a lockout lever, a stop structure, and a lock-on member. The housing defines an interior space, and has a forward housing portion defining a forward housing opening and a rearward housing portion defining a rearward housing opening. The drive member extends through the forward housing opening, and is configured to be moved in a repeating pattern. The motor is positioned in the interior space and is configured to move the drive member in the repeating pattern. The switch is positioned in the interior space and has an actuator movable between an actuated and a deactuated position. When the switch is in the actuated position, the motor moves the drive member in the repeating pattern, and when the switch is in the deactuated position, the motor does not move the drive member in the repeating pattern.
Abstract:
A pyrotechnic actuator for a power cutting tool is disclosed. The pyrotechnic actuator comprises a housing defining a cavity therein, a piston positioned at least partially within the cavity, and an insert-molded unitary assembly positioned within the cavity. The unitary assembly comprises a piston engagement member and a base. A sealed void is defined intermediate the piston engagement member and the base. The unitary assembly comprises a breakable member extending intermediate the piston engagement member and the base and a pyrotechnic initiator positioned at least partially within the base. The pyrotechnic initiator, upon application of a current pulse thereto, is configured to generate a pressurized gas in the sealed void that exerts a force on the piston engagement member and breaks the breakable member thereby causing the piston engagement member and the piston to move relative to the base and the housing.
