Abstract

In microimage storage and retrieval machines, a cage is brought down to grasp a cell containing film strips or chips, one of which is to be withdrawn from the cell, utilized and then returned. Damage to film strips results if they are not reinserted completely in the cell prior to the time that the cage is moved to another cell. A device used to sense the presence of a partially withdrawn strip must place very little pressure on it to avoid damage.

Film Sensor -- Cage Interlock Mechanism

In microimage storage and retrieval machines, a cage is brought down to grasp a cell containing film strips or chips, one of which is to be withdrawn from the cell, utilized and then returned. Damage to film strips results if they are not reinserted completely in the cell prior to the time that the cage is moved to another cell. A device used to sense the presence of a partially withdrawn strip must place very little pressure on it to avoid damage.

As the cage mechanism is brought down over the cell, an actuator connected to the cage causes the actuator arm to pivot about point 1. This causes the extremity 3 of the actuator arm to bear upon the interlock mount member 4 to which is attached an interlock member 5 and a feeler 6. Pressure of 3 thus causes member 5 to be interposed between the carriage and interlock ledge. Feeler 6 is pivoted to the right against spring action. Feeler 6 and member 5 are pivoted and supported at 7 by support arm 8 which, in turn, is connected to the carriage.

The carriage is movable in a horizontal direction and is interlocked by devices, not shown, such that it cannot move until the interlock ledge fixedly attached to the cage nearly contacts the lower portion of the carriage.

When the cage begins to rise, if the film strip, which has been processed, is fully re-inserted into the cell, feeler 6 by spring action is swung across the top of the cell and member 5 is pivoted from between the carriag...
