Abstract
A multi-pen recording device including a carriage holding a number of pens and movable on a shaft over a writing surface, a single plunger provided for selectively urging a selected individual pen against the writing surface, a belt for driving the carriage attached to the carriage, a clutch provided on the carriage for transmitting the drive force of the belt to the plunger and for releasing the same, whereby the drive force of the belt is used as the drive force for the pen selection and is used as a single plunger for urging a pen against the writing surface which eliminates the need for a special drive source for changing over the plunger toward the respective pens.
