STAPLER
摘要:
A stapler includes a main body, a light-emitting module, and an optical module. The main body has a stapling portion. The light-emitting module is disposed in the main body. The optical module faces the light-emitting module. Light emitted from the light-emitting module is converted into a light spot with a linear shape by the optical module to mark a stapling position of the stapling portion.
