The Panasonic FS-IFA1 is an interface to use peripherals for Panasonic personal word processors U1 series on MSX2 and higher computers.

The peripherals that can be used are listed below:

There are other image scanners (for example FW-RSU1 and FW-RSU1C - C = color), but they are not compatible with this interface and the provided software. Probably the bitstream conversion of black and white dots into a picture is encoded differently.

The top of the cartridge has a Mini-Din connector for the peripherals, and a connector for the provided external FS-AA121 power supply.

It was only sold in Japan.
