Abstract
A data recordable camera is provided with a timer circuit for providing a time data and a timing data, a data recording unit for converting the time data from the timer circuit into an optical image to expose a film, and data display unit for displaying the time data. The timing data is transferred to a motor drive device to determine the operation timing of the motor drive device.
Claims7
A data recordable camera comprising:
- data producing means for producing at least a time data and a timing data;
- data recording means for converting the time data from said data producing means into an optical image to exposure a film;
- data display means for displaying selectively the time data and timing data from said data producing means;
- and
- means for transferring the timing data from said data producing means to a motor drive device whereby the motor drive device is driven at a timing of the timing data.
2 more elements
A data recordable camera comprising:
- a back cover, a board attached to the inside of said back cover, a large scale integrated circuit device including a data producing circuit to produce at least a time data and attached to said board, a data recording unit attached to said board for converting the time data produced from said data producing circuit into an optical image to expose a film, a display unit attached to said board for displaying selectively the time data and timing data from said data producing circuit, and a plurality of operation switches so provided on said board as to operate said switches from said back cover and connected to said integrated circuit device, a terminal portion for leading the data from said integrated circuit device to a motor drive device, wherein said integrated circuit device includes a circuit for producing a timing set signal to set the operation timing of said motor drive device in accordance with an operation condition of said operation switches, and a circuit for producing a signal for driving said motor drive device in response to the timing set signal from said timing setting signal producing circuit and the time data from said data producing circuit.
