Photographic device

Claim 2

A photographing device which effects exposure to record a light image of an object onto a film while the object and the film are moving, comprising; means to feed the film; means to produce pulse signals at a predetermined interval responsive to the film fed; means positioned on the path along which the object moves in order to detect the object; means controlled by the detection signal from said detecting means and by the pulse signal from the pulse generating means in order to record at least one index mark on the film; and switching means which uses a sheet form and a web form as the object and is coupled to said recording means in order to select the mode of mark that will be recorded on the film depending on the form of the object; wherein When the object of the sheet form is being photographed on the film, the first mark is also photographed for the object, and when the object of the web form is being photographed, the second mark is photographed for the object.

Claim 3

A photographing device according to claim 1 wherein said feeding means has a pair of driving rollers, and said pulse generating means including a disc which rotates together with said driving rollers and having slit holes maintaining a predetermined clearance on the periphery of the disc, a light source placed on one side of said disc, and a light-receiving element placed on the other side of the disc to produce pulse signals upon receipt of light from the source of light through slit holes of the disc.

Claim 4

A photographing device according to claim 1 wherein said mark recording means includes a mark generator means which projects a light ray recorded as a mark onto the film, and a control means coupled to said mark generator means to interrupt the light ray projected by the mark generator means depending on the form of the object, in order to control the number of marks that will be recorded on the film.

Claim 5

A photographing device according to claim 3 wherein said control means includes a delay circuit which receives the detection signal and produces a delay signal after a predetermined period of time has passed, a first gate means which, when the switching means is set for the sheet form, gates by the delay signal from the delay circuit to interrupt the light ray projected by the mark generator means, and a second gate means which when the switching means is set for the web form, gates by the delay signal from the delay circuit and by the pulse signal from the pulse generating means in order to interrupt the light ray projected by the mark generator means.

Claim 6

A photographing device according to claim 4 wherein said second gate means includes a synchronization control circuit which produces a synchronizing pulse upon receipt of the initial pulse signal from the pulse generating means after the signal from the delay circuit has been produced to bring the delay signal into synchronism with the pulse signal, and a gate circuit which receives as inputs the synchronizing signal from the synchronization control circuit and the pulse signal from the pulse generating means to gate upon receipt of both inputs.

Claim 7

A photographing device according to claim 3 wherein said mark generator means includes a linear light source, a shutter placed in front of said linear light source, and an optical means which directs the light from the linear light source toward the side of the film, and wherein the light from the linear light source is recorded on the film as a mark.

Claim 8

A flow camera which effects exposure while an object and a film are moving and records a light image of the object onto the film on a reduced scale, comprising; a camera body; an optical lens positioned in the camera body to project the light image of the object onto the film; a roller which transfers the object through the exposure position; a detector positioned on the path along which the object moves to detect the feeding of the object; a drive roller which feeds the film at a speed equal to that of the light image of the object and in the direction opposite to that of the object; a pulse generator connected with said drive roller to produce pulse signals at a predetermined interval responsive to the feeding of film; a light source positioned in the camera body to project a light ray recorded as a mark onto the side of the film; a shutter positioned in front of said light source; a control circuit which receives the signal from said detector switch and the pulse signal from the pulse generator to open and close said shutter depending on the form of the object; and a switch coupled to said control circuit to select the number of marks that will be recorded on the film depending on the form of the object.

Claim 9

A flow camera which effects exposure while an object and a film are moving and records a light image of the object onto the film on a reduced scale, comprising; a camera body; an optical lens positioned in the camera body to project the light image of the object onto the film; a roller which transfers the object through the exposure position; a detector positioned on the path along which the object moves to detect the feeding of the object; a drive roller which feeds the film at a speed equal to that of the light image of the object and in the direction opposite to that of the object; a pulse generator connected with said drive roller to produce pulse signals at a predetermined interval responsive to the feeding of film; a light source positioned in the camera body to project a light ray recorded as a mark onto the side of the film; a shutter positioned in front of said light source; a control circuit which receives the signal from said detector switch and the pulse signal from the pulse generator to open and close said shutter depending on the form of the object; and a switch coupled to said control circuit to select the number of marks that will be recorded on the film depending on the form of the object.

Claim 12

An apparatus according to claim 8, wherein said control means, when the card-like document is selected, permits one shot of the light emission to be incident onto the film for a predetermined time from said index mark recording means; and when the long web-like document is selected, said control means permits a plurality of shots of the light emission to be incident onto the film for predetermined times from said index mark recording means.

Claim 13

An apparatus according to claim 8, further comprising: means for shielding the light from said index mark recording means; and a circuit for controlling said shielding means, said control circuit, when the card-like document is fed, permitting a first mark to be recorded on the film, and when the web-like film is fed, permitting a second mark to be recorded on the film.

Claim 14

An apparatus according to claim 10, wherein said control circuit receives, when the card-like document is selected, a first signal to actuate said shielding means by one time, while said control receives, when the web-like document is selected, a second signal circuit to actuate said shielding means a plurality of times.

Claim 15

An apparatus according to claim 11, wherein said selecting means includes a switch for preventing the recording of the index mark.
