This invention relates to a resettable mechanical counter. It is an object of the invention to provide such a counter in which the means required to reset the counter constitute a key which can be removed from the counter and can be used to reset a plurality of counters so that the counters are simplified and can be manufactured at lower cost. This object is accomplished by the provision of a resetting slider, which is provided with disengaging cams and adapted to be inserted into tracks provided on the frame of the counter and to be removed from said frame.

Resettable mechanical counter

The frame-counting device is primarily intended for use with a film cassette in titling and lap dissolve operations. The film cassette contains an unexposed film having a series of perforations and is of the type having a side wall formed with an opening which defines a film plane and through which the film is exposed. The device includes the following structure: a housing having an aperture for receiving the film cassette with its open side wall ahead, a transport sprocket which is rotatably mounted in the housing and engageable with the perforations of the unexposed film of the cassette received in the aperture of the housing, and a member for shielding the film plane of the cassette as received in the aperture against an access of light. A counter is carried by the housing, which counter is readable from the outside and operatively connected inside the housing to the transport sprocket. In addition, the device is provided with a single frame stepping mechanism, including a stepping wheel operable by a push button to actuate the counter. The stepping mechanism is adapted to be connected to a flexible wire release for use with a motion picture camera for operating the camera for single exposures.

Frame-counting device for use with film cassette

The system serves to digitally collect and store data in readable form and comprises counters for storing data and a main unit, which comprises adapters removably holding respective ones of said counters in counting positions and control means for controlling said counters in said counting positions.

System for digitally collecting and storing data

A plurality of counters are removably held by counter holder means at predetermined locations. Each counter is adapted to perform incremental and decremental counting operations. A program timer is operable to produce first and second control signals in alternation in accordance with a predetermined time schedule. Drive means are carried by said counter holder means and comprise drive output means and are operable under control of said program timer to rotate said drive output means in a decremental sense when said control timer produces said first control signal and in an incremental sense when said control timer produces said second control signal. A plurality of clutch means are carried by said counter holder means and connected to said drive output means and associated each with one of said counters. Each of said clutch means is adapted to assume a first state for driving the associated counter in an incremental sense and a second state for driving the associated counter in a decremental sense. A plurality of code detectors are provided, each of which is associated with one of said counters and comprises code detector elements and is adapted to receive an identification code carrier in a predetermined position and to assume a first state in response to an insertion of a mating identification code carrier having code elements, which represent the same code as said code detector elements, and a second state in response to the removal of such mating identification code carrier. A plurality of clutch-shifting means are carried by said counter holder means and associated with respective ones of said clutch means and of said code detectors and adapted to cause the associated clutch means to assume said first and second states in response to said first and second states, respectively, of the associated code detector.

System for collecting data

The counter means serve for a counting of events. A counter is provided as well as a code detector adapted to receive a coded punched card in a predetermined position. Counter control means are operable to control said counter in response to the arrival of said card in said predetermined position. Said code detector comprises replaceable, pivoted code detector elements, which represent a predetermined code and are adapted to enter holes in said punched card if, and only if, said holes also represent said predetermined code. Said code detector prevents a movement of said card to said predetermined position unless said code detector elements have entered said holes in said card.
