Abstract
A cutter unit for carrying a cutter for cutting a phonographic record includes a cutter carrier and a cutter head. The cutter head is carried by the cutter carrier and arranged to be displaced relative to the cutter carrier, in particular to rotate around a cutter pivot, the cutter unit being arranged in a cartridge enclosing and protecting the cutter unit.
Claims14
A cartridge comprising a cutter unit for carrying a cutter for cutting a phonographic record,
- the cutter unit comprising a cutter carrier and a cutter head,
- the cutter head being carried by the cutter carrier and arranged to be displaced relative to the cutter carrier,
- the cutter unit being arranged in the cartridge enclosing and protecting the cutter unit,
- the cutter head carrying an advance ball for maintaining a constant distance between the cutter and the phonographic record, a height of the advance ball relative to the cutter being adjustable by an adjustment mechanism, the adjustment mechanism comprising an advance ball carrier carrying the advance ball, the advance ball carrier being mounted to be adjustably displaced relative to the cutter head, and to rotate, relative to the cutter head, around an advance ball carrier pivot,
- wherein the cutter head is arranged to rotate relative to the cutter carrier around a cutter pivot, the advance ball carrier is arranged to rotate, relative to the cutter head, around the advance ball carrier pivot, and an axis of rotation of the cutter pivot and an axis of rotation of the advance ball carrier pivot are at a right angle to one another.

A cartridge comprising a cutter unit for carrying a cutter for cutting a phonographic record,
- the cutter unit comprising a cutter carrier and a cutter head,
- the cutter head being carried by the cutter carrier and arranged to be displaced relative to the cutter carrier,
- the cutter unit being arranged in the cartridge enclosing and protecting the cutter unit;
- wherein the cutter head is displaceable relative to the cutter carrier by cutting forces acting on the cutter and/or a weight of the cutter head, this weight being counteracted by at least one of a counterweight and a cutter spring, the cutter spring being in a pre-stressed state;
- and,
- wherein the cutter head is arranged to rotate relative to the cutter carrier around a cutter pivot, and the cutter head being rotatable around the cutter pivot by the cutting forces acting on the cutter and/or the weight of the cutter head, this weight being counteracted by the at least one of the counterweight and the cutter spring, the cutter spring being in the pre-stressed state, and wherein the cutter spring acts on a counter arm opposite to the cutter head, relative to the cutter pivot.
