Abstract: A linear transport system includes a stator having a track and coils provided along the track, carriers with a magnet and movable along the track, scales provided on the carriers, sensors provided along the track at respective intervals and configured to detect the carriers to obtain scale positions of the scales, a parameter memory configured to memorize first cumulative values each corresponding to a corresponding sensor, and position calculation circuitry. Each of the first cumulative values is obtained by accumulating, from a reference position to the corresponding sensor, error correction values based on which errors between the respective intervals and measured values of the respective intervals are corrected. The position calculation circuitry is configured to calculate a position of a detected carrier based on detection data of a detecting sensor that has detected the detected carrier and based on the first cumulative value corresponding to the detecting sensor.

Abstract: A stapler movable between a rest position and a stapling position and having a front end and a rear end. The stapler includes a base, a staple magazine coupled to the base and configured to hold staples, and a driver blade operable to drive staples out of the staple magazine during stapling operations. The stapler further includes an elastic member coupled to the driver blade and operable to move the driver blade during stapling operations. The elastic member utilizes potential energy to move the driver blade during stapling operations. The driver blade is positioned above the staple magazine when the stapler is in the rest position and the magazine is extendable from the front end of the stapler to allow a user to load staples in the magazine. The stapler is configured such that only the potential energy of the elastic member can operate the driver blade during stapling operations.

Abstract: [Object] To provide a stapler for fastening papers or the like, which can perform a proper stapling operation even though a handle thereof is given smaller force, can perform a stronger stapling operation, can reduce the production cost due to fewer parts and simple structure, and has a structure in which a structure in which staples does not accidentally pop out when refilling staples. [Solve] By pushing down a handle, a trigger member moves a puller or pusher member, and the movement of the puller or pusher member moves a fulcrum shaft B, which results in that an angle formed by a fulcrum shaft A, the fulcrum shaft B, and a fulcrum shaft C becomes closer to 180 degrees. In accordance with this, one end of a driver spring moves to the upper side to save power in the driver spring, and by pushing down the handle, the engagement between the trigger member and the puller or pusher member is released.

Abstract: A desktop stapler includes a base configured to rest on a support surface, a cover, and a magazine. The stapler further includes an elastic member, a driver blade, and a support member. The elastic member is positioned at least partially between the cover and magazine and stores energy applied to the cover as the cover is moved relative to the magazine. The driver blade is coupled to an end of the elastic member and is configured to push out staples from the magazine. The support member selectively engages the elastic member and energy is stored in the elastic member as the cover is moved relative to the magazine. The elastic member is engaged with a portion of the support member. Energy stored in the elastic member is released when the elastic member disengages from the portion of the support member, causing the driver blade to push out a staple.

Abstract: A large cassette type stapler allowing, with a simple structure, a locking means for fixing a cassette mounting position to be installed on the rear end lower surface of a cassette, comprising a locking means (15) having a spring (14) for energizing the cassette in extracting direction which is fitted to the rear end of the cassette, a locking projected part (16) provided on the rear end lower surface of the cassette (5), and a hook (21) capable of being automatically locked to the locking projected part (16) when upwardly rotated by the energization of a spring (22) installed on a base (1) side opposed to the locking projected part and unlocked by manually pushing down.

Abstract: A cassette for stapler capable of storing staples with different lengths of needle legs and capable of being manufactured at a low cost, comprising a cassette body formed slender with a channel shaped cross section and having a staple extrusion groove provided at the tip thereof, a staple holder longitudinally fitted to the cassette body to hold the large number of staples, a feeder for moving the staples pressingly toward the tip thereof, a spring for energizing the feeder, and a guide rod for guiding the movement of the feeder, wherein a guide wall capable of storing the staples with different lengths of needles is provided in the staple holder.

Abstract: A cassette of a cassette type stapler, wherein a holder structural body (1), staple guides (8), and a spring engaging device (9) of the holder structural body are molded integrally with each other, a spring is fitted to the spring engaging device (9) of the holder structural body and the feeder projection (21) of a feeder (20), and the feeder (20) pushes a staple forward. Namely, a mechanism functioning as a conventional outer box is formed integrally with a mechanism guiding the staple. Also, in the mechanism functioning as the outer box, a rear wall or a bottom wall is not separated from the outer box but formed integrally therewith. In addition, a structure to directly engage one end of the spring with a holder body and the other end with the feeder and a structure to guide the staple to a specified position when the staple is struck out are used for the mechanism guiding the staple. A member for engaging the spring with the holder body and a staple guide member are required for these structures.
