Claims
- 1. An electronic apparatus comprising:
a frame; and a raised portion provided on that region of said frame which engages an ejector pin projecting from inside a mold device and formed thicker than the peripheral portion of said engaging region at the least.
- 2. An electronic apparatus according to claim 1, wherein said raised portion is surrounded by ribs for reinforcement.
- 3. An electronic apparatus comprising:
a frame; and a protrusion provided on that region of said frame which engages an ejector pin projecting from inside a mold device and formed projecting from the peripheral portion of said engaging region at the least.
