Abstract

PURPOSE: To improve reliability by exchanging data between a memory pack and a device main body without contact.
CONSTITUTION: When a font cassette 61 being a memory pack is loaded on the cassette holder 48 of a printer main body, a data transmission light emitting element 51, a data reception photodetecting element 52 and a power supply light emitting element 53 at the side of the printer main body face the data reception photodetecting element 71 and data transmission light emitting element 72 of the font cassette 61 and a solar battery 73. A master microprocessor 82 requests the transmission of pattern information from the font cassette 61 through a serial transfer element 100, and receives said information transmitted from the font cassette 61. In such a way the font cassette can transmit and receive the data between the printer main body under noncontacting state, and data is not damaged due to a noise, etc., thereby improving the reliability.
