Abstract: The card guide device is for supporting a card and includes a stationary guide and a movable guide for transport. The movable guide is movable toward and away from the stationary guide. A pair of card guide grooves are respectively formed on each of opposed surfaces of the stationary guide and the movable guide. Each groove has an inside dimension larger than the thickness of the card to be transported therethrough.

Abstract: A magnetic head retaining device, comprising a support member carrying a magnetic head which contacts a magnetic recording medium such as a magnetic card moving in one direction relative thereto and at least a pair of support holes provided downstream and upstream to the magnetic head on an imaginary line passing through the magnetic head in parallel to the direction of the motion of the magnetic recording medium and a mounting member having at least a pair of legs inserted through the corresponding support holes and a spring portion for biasing the legs downwards. Each of the legs is provided with a step for restricting the upward motion of the supporting member. By forming the mounting member out of a single plate, the device may have the flexibility required for achieving an intimate contact between the magnetic head and the magnetic medium and the rigidity required for accurately positioning the magnetic head.
