In a rotary powder compression molding machine in which a rotary turret is provided within a frame via a vertical shaft so as to be horizontally rotatable, a plurality of dies are provided in the rotary turret at a predetermined interval, an upper punch and a lower punch are held kept above and below each of the dies so as to be vertically slidable, a powder filled in the die is compressed and molded by putting the upper punch and the lower punch in which punch tips are inserted into the dies through a portion between an upper roll and a lower roll, a joint apparatus coupling the vertical shaft and the rotary turret so as to be able to detach the rotary turret from the vertical shaft, comprises a coupling mechanism coupling the vertical shaft and the rotary turret while maintaining a state in which the vertical shaft and the rotary turret are constrained in an axial direction of the vertical shaft with each other, and canceling the coupling between the vertical shaft and the rotary turret by canceling the constraining state on the basis of an operation; and a coupling detecting mechanism detecting a fact that the rotary turret is coupled to the vertical shaft by the coupling mechanism.

The invention claimed is: 1. A rotary powder compression molding machine in which a rotary turret is provided within a frame via a vertical shaft so as to be horizontally rotatable, a plurality of dies are provided in the rotary turret at a predetermined interval, an upper punch and a lower punch are held kept above and below each of the dies so as to be vertically slidable, a powder filled in the die is compressed and molded by putting the upper punch and the lower punch in which punch tips are inserted into the dies through a portion between an upper roll and a lower roll, comprising a joint apparatus coupling the vertical shaft and the rotary turret so as to be able to detach the rotary turret from the vertical shaft, wherein the joint apparatus comprises: a coupling mechanism coupling the vertical shaft and the rotary turret while maintaining a state in which the vertical shaft and the rotary turret are constrained in an axial direction of the vertical shaft with each other, and canceling the coupling between the vertical shaft and the rotary turret by canceling the constraining state on the basis of an operation; and a coupling detecting mechanism detecting a fact that the rotary turret is coupled to the vertical shaft by the coupling mechanism, wherein the coupling mechanism comprises: a constrained member attached to the rotary turret; and a constraining means attached to the vertical shaft so as to constrain the constrained member on the basis of an resilient force, the constraining means actuating in an opposite direction to the resilient force to relieve a constrained state by hem supplied a fluid having a fluid pressure over the resilient force. 2. The rotary powder compression molding machine as claimed in claim 1, wherein the coupling detecting mechanism comprises: a gas supply means for supplying a gas in such a manner that the constraining means passes between contact surfaces with which the constraining means is brought into contact at a time of constraining the constrained member; and a detecting means for detecting a charge of gas property, the change being caused by a flow of the gas supplied by the gas supplying means being limited by the portion between the connect surfaces. 3. A rotary powder compression molding machine in which a rotary turret is provided within a frame via a vertical shaft so as to be horizontally rotatable, a plurality of dies are provided in the rotary turret at a predetermined interval, an upper punch and a lower punch are held kept above and below each of the dies so as to be vertically slidable, a powder filled in the die is compressed and molded by putting the upper punch and the lower punch in which punch tips are inserted into the dies through a portion between an upper roll and a lower roll, comprising a joint apparatus coupling the vertical shaft and the rotary turret so as to be able to detach the rotary turret from the vertical shaft, wherein the joint apparatus comprises: a coupling mechanism coupling the vertical shaft and the rotary turret while maintaining a state in which the vertical shaft and the rotary turret are constrained in an axial direction of the vertical shaft with each other, and canceling the coupling between the vertical shaft and the rotary turret by canceling the constraining state on the basis of an operation; and a coupling detecting mechanism detecting a fact that the rotary turret is coupled to the vertical shaft by the coupling mechanism, wherein the coupling mechanism comprises a constrained member attached to one of the rotary turret and the vertical shaft, and a constraining means attached to an opposite position to the constrained member so as to constrain the constrained member on the basis of an resilient force, the constraining means actuating in an opposite direction to the resilient force to relieve a constrained state by being supplied a fluid having a fluid pressure over the resilient force, and wherein the constrained member comprises a through hole, the through hole providing a taper surface portion defined by a large inner diameter portion and a small inner diameter portion having a smaller diameter than the large inner diameter portion, and an annular convex portion having a smaller inner diameter than the small inner diameter portion of the taper surface portion, and the constraining means comprises a case providing a projection portion having a taper outer surface corresponding to the taper surface portion of the constrained member, a plurality of spherical bodies held so as to be movable in a position near the taper outer surface of the projection portion, a spherical body pressing member having a rod portion arranged within the case and pressing each of the spherical bodies against the annular convex portion when the rotary turret and the vertical shaft are in a coupling state, and a transmission portion coupled to the rod portion and arranged within the case in a state of being partly exposed from the interior of the case, a resilient body supplying a resilient force to the spherical body pressing member, and a base member having a concave portion capable of installing the case in the portion where the spherical body pressing member is exposed in a liquid tight manner, thereby relieving the constraint of the constrained member by introducing a fluid to the concave portion of the base member. 4. The rotary powder compression molding machine as claimed in claim 3, wherein the coupling detecting mechanism comprises: a gas supply means for supplying a gas in such a manner that the constraining means passes between contact surfaces with which the constraining means is brought into contact at a time of constraining the constrained member; and a detecting means for detecting a charge of gas property, the change being caused by a flow of the gas supplied by the gas supplying means being limited by the portion between the connect surfaces.
