Embodiments of film input in the image input apparatus of the present invention will be described in detail below. In this apparatus, a conventional film (film without a magnetic layer) 23 and a magnetic film 32 coated with a magnetic recording layer can be attached. The film holder 22 for accommodating the conventional film 23 will be described with reference to FIG.

The film holder 22 has a holding portion 2 from the center.
It has a structure in which the developed conventional film 23 is sandwiched by being divided into two parts 2a and 22b. The conventional film 23 is maintained by the film holder 22 so as to keep its shape flat, and is not twisted or bent. Since the flat surface of the conventional film 23 is maintained, there is an effect that it becomes easy to perform focus adjustment even with a lens having a narrow depth of field.

The film transmitted light window 51 is a window arranged so that a film image can be seen from the outside. Feeding rack 5
A rack 3 is used for moving the film holder 22. On the magnetic layer 55, film information is magnetically recorded,
It is to be read. The magnetic head 20 and the magnetic head 27 shown in FIGS. 6 and 9 write magnetic recording information to the magnetic layer 55 and read from the magnetic layer 55. By having the magnetic layer 55, it is possible to store information regarding the conventional film 23 having no magnetic layer. Therefore, once the trimming information of the zoom lens is set, there is an effect that the set value does not have to be input many times.

The frame position detecting hole 52 and the start position / end position detecting hole 52 'are holes used for positioning the film holder 22 by a method described later. Next, the magnetic film 32 will be described with reference to FIG. The magnetic film 32 corresponds to the image pickup range 54, and 1 for one image.

The rotary positioning pin 14 is used for positioning to make the conventional film surface and the magnetic film surface the same with respect to the optical axis direction. Fall control pin 1
2 engages with the groove 36 to prevent the cassette holder 33 from tilting. The cassette holder 33 is vertically positioned by the opening / closing lid 24, the supply reel 18, and the take-up reel 18 '.

As described above, in the apparatus of the first embodiment, the rotary positioning pin 14 is shared for positioning the film holder 22 and the cassette holder 33 in the optical axis direction, and the positioning reference is the same. Therefore, the position adjustment in the optical axis direction becomes easy. In addition, the number of parts is reduced and the cost can be reduced. Next, a method of housing the cassette holder 33 in the film input section will be described.

As shown in FIG. 9, the cassette holder 33 can be inserted with the opening / closing lid 24 opened. The user inserts the cassette holder 33 into the cassette storage openings 19 and 19 ′ while aligning the rotation positioning pin 14 and the tilting restriction pin 12. Then, the user closes the opening / closing lid 24. Then, as shown in FIG. 10, the cassette holder 33 is pressed downward by the pressing pin 29. The pressing pin 29 is provided on the opening / closing lid 24 and is urged downward by the coil spring 60.
Due to this biasing force, the cassette holder 33 is fixed at an accurate position in the vertical direction.

As shown in FIG. 9, the magnetic head 20 is configured to move forward and backward in the direction of the arrow by a head shift mechanism (plunger) 64.
