Abstract
In an imaging apparatus for forwardly and reversely photographing images on two rows of film, the leader of the film is transported in a set amount before starting photographing images on the first row, and after photographing on the second row terminates, the trailer of the film is transported in an amount set on the basis of the amount of the leader transport.
Claims23
An imaging apparatus for forwardly and reversely photographing images on two rows of a recording medium, said apparatus comprising:
- imaging means for recording an image onto the recording medium;
- transport means for forwardly and reversely transporting the recording medium between a supply section and a take-up section;
- first setting means for setting the amount of leader transport on the first row of the recording medium to a first value;
- second setting means for setting the amount of trailer transport on the second row of the recording medium to a second value on the basis of the amount of the leader transport set by said first setting means;
- and
- transport control means for controlling the amounts of the leader transport and trailer transport of the recording medium on the basis of the values set by said first and second setting means.
An imaging apparatus for forwardly and reversely photographing images on two rows of a recording medium, said apparatus comprising:
- imaging means for recording an image on the recording medium;
- leader transport means for transporting a leader of the recording medium on the first row at which forward photographing is performed;
- trailer transport means for transporting a trailer of the recording medium on the second row at which reverse photographing is performed;
- first setting means for setting the amount of the leader of the recording medium;
- and
- second setting means for setting the amount of the trailer of the recording medium on the basis of the amount of the leader transport set by said first setting means.
A method for operating an imaging apparatus for forwardly and reversely photographing images onto two rows of a recording medium, said method comprising the steps of:
- supporting the recording medium between a supply section and a take-up section for movement in a forward direction and in a reverse direction;
- setting the amount of leader transport on the first row of the recording medium to a first set value;
- recording images of an original document on the first row of the recording medium as it moves in the forward direction;
- reversing the direction of movement of the recording medium;
- recording images of an original document on the second row of the recording medium as it moves in the reverse direction;
- setting the amount of trailer transport on the second row of the recording medium on the basis of the amount of the leader transport to a second set value;
- and
- controlling the amounts of the leader transport and the trailer transport of the recording medium on the basis of the first and second set values.
