イルムに極めて多量の情報を収めることができる。<Background Art> While office automation is being promoted to improve the efficiency and productivity of office departments, it is required to establish a system that rationalizes the storage of large amounts of document materials and printed materials. A microfilm has been conventionally used as an effective means therefor. This microfilm is a document, printed matter, or the like reduced in size to 1/8 to 1/40 and recorded, and when read out, it is enlarged and projected on a screen or copied.
In any case, a very large amount of information can be stored in one roll-shaped or fish-shaped film.

に行なうことが可能となる。Therefore, a microfilm using an electrophotographic body that can add or correct information later has been developed. This electrophotographic film is different from a conventional photographic film using a silver salt, in which a conductive layer and a photoconductive insulating layer are provided on an insulating support (base), or a photoconductive film is provided on a conductive layer which also serves as a support. It is formed by superimposing a conductive insulating layer. Therefore, it is not photosensitive unless charged, and has a feature that the development processing time, space, and the like are small. Taking advantage of such features, the electrophotographic film formed in a roll shape or a fashioned shape is provided with an interval, for example, one frame of image information is recorded for each theme, and these image information can be recorded later as needed. This makes it possible to extremely easily perform a method of using, for example, additionally recording new related image information adjacent to the recorded image information.

る。In recent years, miniaturization, weight reduction, and systematization of a reader / printer for enlarging and projecting image information recorded on the above-described electrophotographic film have been promoted, and along with this, ease of management and storage of the electrophotographic film. Or, considering compatibility, it is desirable to make the roll type into a cassette type, but unlike the conventional magnetic tape and silver salt microfilm, the electrophotographic film has its conductive layer grounded when it is charged. I need to put it. That is, the electrically conductive layer of the electrophotographic film wound on the reel housed in the pair of cassette halves constituting the cassette case is electrically connected to the main body of the apparatus, but since the reel rotates, it is normally stationary. The method of grounding is not applicable.

In the present embodiment, focusing on the fact that it is necessary to elastically press the reels 15 and 16 toward the lower cassette half 12, the lead plate 28 and the reel 16 attached to the upper cassette half 11 and extending to the upper surface of the reel 15 are provided. The leaf spring 30 that elastically presses the upper surface is formed of a conductive material and
Of the grounding member, and further open a grounding window 31 in the upper cassette half 11 at a position facing the leaf spring 30, and from here,
A grounding member (second grounding member) 32 of an electrophotographic apparatus (not shown) is fitted and is in contact with the leaf spring 30. Therefore,
The conductive layer 19 of the electrophotographic film 17 includes a lead plate 28 and a leaf spring 3
0, and is grounded to the device side via the grounding member 32.
Since the leaf spring 30 is always brought into contact with the lead plate 28 due to its elastic force, the two are in sliding contact with each other even while the reel 15 is rotating, and the grounding is not interrupted. In the present embodiment, the protrusion 28a is provided on the lead plate 28 so as to match the rotation center line of the reel 15.
Even when the reel 15 rotates, the protrusion 28a is in sliding contact with the leaf spring 30 at almost one point.
