What is claimed is:
1. A disk carrier device of a disk player carrying a disk, using a carrier roller, wherein
the carrier roller has a tapered surface with the diameter thereof becoming smaller gradually from the opposite ends towards the center, there is provided a disk guide member integrally formed with a pair of tilted protrusions in the front and rear parts thereof which become gradually lower from the opposite ends towards the center, and the carrier roller is arranged between the pair of tilted protrusions to resiliently clamp the disk between the both tilted protrusions and the carrier roller to thereby carry the disk by the rotation of the carrier roller.
2. A disk carrier device of a disk player according to claim 1, wherein a tilted protrusion on the inner side than the carrier roller, of the pair of tilted protrusions of the disk guide member is located at a higher position than a tilted protrusion on this side of the carrier roller.
3. A disk carrier device of a disk player according to claim 1 or claim 2, wherein a recess for avoiding abutment with the large diameter portion of the carrier roller is provided between the pair of tilted protrusions of the disk guide member.
4. A disk carrier device of a disk player according to claim 3, wherein the recess is formed by an opening provided between the pair of tilted protrusions of the disk guide member.
5. A disk carrier device of a disk player according to claim 3, wherein the recess is formed by a depression provided between the pair of tilted protrusions of the disk guide member.
6. A disk carrier device of a disk player according to claim 1 to claim 5, wherein the disk guide member is integrally formed of a metal plate.
7. A disk carrier device of a disk player according to claim 1 to claim 6, wherein the disk guide member is obtained by outsert molding, by using a synthetic resin for the pair of tilted protrusions.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. The use of a presynaptic neurotoxin for the manufacture of a medicament for the promotion of normal muscle growth in a juvenile patient suffering from dynamic contractures due to cerebral palsy.
2. The use according to claim 1 wherein the presynaptic neurotoxin is a bacterial neurotoxin.
3. The use according to claim 2 wherein the bacterial neurotoxin is a botulinum toxin.
4. The use according to claim 3 wherein the botulinum toxin is botulinum toxin A.
5. The use according to any one of the preceding claims wherein the medicament is for the treatment of a human up to six years in age.
6. A method of treating a juvenile patient suffering from arrested muscle growth arising from the presence of dynamic contractures of the muscle, which method comprises administering to the patient a therapeutically effective amount of a substance which blocks the release of synaptic vesicles containing acetylcholine.
7. A method of promoting normal muscle growth in a juvenile patient suffering from dynamic contractures due to cerebral palsy, which method comprised administering to the juvenile patient a therapeutic amount of a presynaptic neurotoxin, for example a bacterial neurotoxin such as botulinum toxin.
8. A method according to of claim 7 wherein the juvenile patient is a human up to six years in age.
9. A method according to of claim 7 or claim 8 wherein the said substance or presynaptic neurotoxin is a botulinum toxin.
10. A method according to claim 9 wherein the botulinum toxin is botulinum toxin A.
11. A method according to claim 9 or claim 10 wherein the botulinum toxin is administered by intramuscular injection, e.g. into a spastic muscle.
12. A method according to claim 9 or claim 10 wherein the botulinum toxin is administered by intramuscular injection into the calf muscle or hamstring.
