8. MECHANISM AND OPERATION PRINCIPLE
8-1. Mechanism
As illustrated in Fig. 3, the Model N 5024A can be generally divided into four sections:
output section, control valve section, driving section and magazine section.
The driving section (nose and piston) and the magazine section have been newly designed though its basic
construction is the same as that of the Model N 5008AC (valve section is common to the Model N 5008AC).
Primary differences from the Model N 5008AC are described below.
Output section ........ The piston (driver blade) has been newly designed according to the shape of the
staple firing gate. Owing to the enlargement of the driver blade, the piston bumper has
been newly designed.
Driving section ........ All the parts have been newly designed for driving staples.
If staples are clogged in this section, they can be easily released simply by pulling
the lock lever by hand.
Magazine section .... All the parts have been newly designed for driving staples.
The magazine cover is opened by pulling the staple feeder backward for easy loading or
replacement of staples.
The <Bold> numbers in the figure below correspond to the numbers in "8-2. Operation Principle".
