Cassette processing apparatus
View Patent ↗A cassette processing apparatus has a plurality of stack units for holding respective cassettes in an array, and a tilting mechanism for tilting the cassettes held by the respective stack units at respective different angles depending on the types of the cassettes. The tilting mechanism has a rotatable shaft connected to a rotary actuator, and a plurality of eccentric cams held in respective angular positions by the rotatable shaft to adjust the angles at which the stack units are tilted thereby to set angles at which the cassettes are titled.
1. A cassette processing apparatus for use with at least one of a cassette loader for loading a cassette housing a recording medium capable of storing radiation image information and a cassette unloader for unloading the cassette, comprising:
a plurality of stack units for holding respective cassettes in an array; and
a tilting mechanism for tilting said cassettes held by the respective stack units at respective different angles depending on the types of said cassettes.
2. A cassette processing apparatus according to claim 1 , further comprising:
a detecting mechanism for detecting the types of said cassettes; and
a control mechanism for controlling said tilting mechanism based on the types of said cassettes detected by said detecting mechanism.
3. A cassette processing apparatus according to claim 2 , wherein said detecting mechanism comprises:
an identifier mounted on each of said cassettes and recording the type of the cassette therein; and
a detector mounted in the cassette processing apparatus, for reading said identifier.
4. A cassette processing apparatus according to claim 1 , wherein each of the types of said cassettes includes at least a dimension of said cassette or the sensitivity of said recording medium.
5. A cassette processing apparatus according to claim 1 , wherein each of said stack units is L-shaped as viewed in side elevation, and is angularly movably mounted on a support shaft, each of said stack units comprising:
a holding arm for holding a bottom surface of the cassette thereon; and
a rear arm for bearing a side of the cassette.
6. A cassette processing apparatus according to claim 5 , wherein said tilting mechanism comprises:
a rotatable shaft connected to a rotary actuator; and
a plurality of eccentric cams connectably mounted on said rotatable shaft by respective clutches, and each held in contact with a lower surface of said holding arm for keeping said holding arm at a predetermined angular position.
7. A cassette processing apparatus according to claim 5 , wherein said tilting mechanism comprises a plurality of cylinders each held in contact with the lower surface of said holding arm.
