The medium supporting device comprises an electrostatic chucking mat generating an electrostatic chucking force by being energized, and a support for supporting the electrostatic chucking mat movably in a first direction. The support is removably connected to a cutting plotter. The cutting plotter includes a medium feeding mechanism for moving a medium reciprocally in the first direction. The electrostatic chucking mat is moved by the medium feeding mechanism while the medium is chucked.

A punching and binding machine used to bind sheets to discs. The machine may include a lever with a first arm, a second arm, and a third arm. Each arm may be pivotally and slidably connected to minimize the force required by a user to punch cutouts in a stack of sheets. The lever may include a flipper connected to a binding member to actuate punching and binding simultaneously.

An apparatus includes a motor, a pinion coupled to the motor, a rack engaged with the pinion, and a housing body assembly configured to hold a working tool. The motor is configured to drive rotation of the pinion and the rotation of the pinion is configured to drive linear translation of the rack. The rack is operably coupled to the housing body assembly such that the linear translation of the rack is configured to urge the housing body assembly along a first axis in a first direction to move the working tool relative to a workpiece.
