guest book; visitors' book
A formal register for recording the names of visitors, often used at events, hotels, or official receptions.
There is a guest book at the reception desk, so please sign it.
芳名録 is a general term for a register of names, while 来客芳名録 specifically refers to a guest book for visitors.
記帳台 is the physical desk or table where a guest book is placed, not the book itself.
Compound of 来客 (visitor) + 芳名 (esteemed name) + 録 (record). The exact historical derivation is uncertain, but the word follows a common pattern for formal registers.
