专利汇可以提供Telephone answering machine message received and footage indicator专利检索，专利查询，专利分析的服务。并且In a telephone answering machine, the present invention is for a message received and footage indicator which includes a take-up reel which has a central cylindrical portion about which the tape is wound and which is provided with a circumferential slit disposed in a plane substantially normal to the axis about which the take-up reel rotates. A feeler is provided mounted proximate to the take-up reel and mounted for pivotal movement in the plane of the slit. An indicator assembly is coupled to the feeler. A helical spring having one fixed end and the other end engaged with the indicator assembly is arranged to move the indicator assembly, including the feeler, to a first position when the slit is exposed and the feeler enters the same. The indicator assembly moves to a discreet second position against the action of the helical spring when the slit is covered by at least one layer of tape and the feeler is prevented from entering into the slit. The second position signifies that at least one message has been received and the take-up reel has moved from a totally unwound condition to at least a partially wound condition. The indicator assembly gradually and continuously moves in a direction beyond the second position against the action of the helical spring when additional tape is wound on the take-up reel and the feeler is displaced by the increased accumulation of tape about the central cylindrical portion. The position to which the indicator moves beyond the second position provides an indication of the extent to which recorded tape has been wound onto the take-up reel.，下面是Telephone answering machine message received and footage indicator专利的具体信息内容。
