Abstract
A device for periodic, automatic, readable recording of a meter value from a consumption measuring meter including a casing attachable to an otherwise conventional meter and provided with a slot, a printing unit disposed within the casing and located out of the plane of the slot in order to be tamper-proof, the printing unit being composed of an identification data printer and a consumption value printer and being adapted upon insertion of a record card in the slot of the casing to apply to the record card a visually readable marking of the identification data and meter consumption value, and a push button connected to the printing unit and manually actuable for causing the marking to be applied to the record card by shifting the printing unit towards the record card inserted into the casing through the slot.
