Description

DETAILED DESCRIPTION OF THE INVENTION This invention is an improved film cassette which generally includes an apparatus for exposing each selected portion of the film at a different time so that multiple images can be recorded on a single film plate. Regarding the holder. This invention is primarily utilized in imaging devices such as oscilloscope cameras, which produce a hard copy of soft information produced by the imaging device in a cathode ray tube, which is primarily used by doctors.

When it is necessary to create a printed or hardcopy record of multiple images, multiple images can be placed on a single cathode ray tube (CRT), as demonstrated by many conventional imaging devices. It has been common practice in the prior art to form . In the conventional technology, the formation of multiple images is
performed by an oscilloscope camera and a suitable electronic control circuit connected to the oscilloscope camera,
A required image is processed to a suitable size and formed in a specific partial area of the cathode ray tube,
other areas of the cathode ray tube are left blank;
Further, subsequent images are sequentially formed on the blank areas of the aforementioned cathode ray tube, ultimately resulting in multiple images being exposed onto a single photographic record. The electronics required to perform image shifting, sizing, and blanking are relatively complex and expensive, even with the advent of modern microcircuitry. As you can imagine, this is difficult to maintain. Such complex devices must be installed by specially trained technicians, they require specific calibrations, and they also involve deviations from calibration problems. In addition, C.R.T.
has resolution limits inherent in its design. Therefore, even if optical magnification of the CRT image is achieved prior to recording on film, sizing will result in a lower resolution image. In some cases these shortcomings have been recognized and attempts have been made to correct them, usually by providing a very high resolution oscilloscope or other equipment which unnecessarily increases the cost of the imager.

Another method commonly utilized to produce a large number of hard images is an oscilloscope camera, such as the one manufactured by Polaroid Corporation.
The use of a camera that produces one image per film plate. This is a disadvantage whether or not Polaroid Corporation's self-developing film is used. This is because multiple photographs, each forming a separate image, are more expensive than a single film with multiple images of the same size. With self-developing films, the desired wide range of film types is not available, and the imaging device is less flexible than with others.

This invention of a hand-positioned framed film cassette holder for producing multiple images on a single film plate overcomes all of the problems previously mentioned. The main mechanism for solving this problem is to move the film cassette relative to the frame device so that only a defined portion of the film is exposed through the camera device at any given time.
This is achieved by suitable mechanical devices. In the preferred embodiment, the cassette holder uses a conventional double sided sheet film cassette well known in the photographic art. The cassette mounted along the holder is movable in the X and Y directions along a labyrinth flange which also acts as a light shield. A stop is provided on the flange to limit movement of the cassette within a defined range, and an additional stop engagement device is also provided to allow three or more images to be recorded on a single sheet of film. Provided for positioning an intermediate position. A curtain or sliding shading plate is also provided with the flange,
By moving the cassette holder, light entering the camera through the opening is blocked.

Therefore, according to the improved film cassette holder of this invention, unlike the prior art,
Printing multiple images without partially blanking the CRT screen, reducing image size, or interacting with CRT control electronics to position images at different locations on the CRT screen Records (hard records) can be created. Such conventional techniques have low clarity, low resolution, and lack accuracy. The device of this invention can achieve the above effects without sacrificing the flexibility of use with various types of sheet film. Multiple images are formed on a single film plate. Since only one sheet of normal size film is required for processing, it provides great convenience to doctors, nurses, secretaries, etc. in reading, filing, and storing the film.

It is therefore a principal object of this invention to provide an apparatus for adapting a conventional oscilloscope camera and an oscilloscope to record multiple images on a single film plate.

Another objective is to reduce the cost of multi-image hardcopy recording devices relative to CRT displays.

Another object is to provide a multi-image film cassette holder that can be used with a wide variety of camera bodies.

Another object is to provide a multi-image film cassette holder that can be used in relatively restricted locations by using nested or overlapping blackout panels or flexible curtains.

Another object is to provide a multi-image film cassette holder that can be used with conventional sheet film cassettes.

Another object is to provide a film holder in which the cassette can be positioned in multiple directions without interfering with adjacent structures.

The foregoing and other objects and advantages of the invention will become apparent from the following detailed description of the preferred embodiments with reference to the drawings.

In FIG. 1, reference numeral 20 denotes an improved multi-image film cassette holder of this invention, which is attached to an oscilloscope/camera 22, which is the image forming device in this example, by a suitable adapter 24 as shown in FIG.

In this example, a desired portion of the photosensitive medium, that is, the photographic film 32, is exposed. Film 32 is movable within its cassette 34 relative to opening 30 in both horizontal and vertical directions in FIG. This horizontal and vertical or
The movement in the Y direction is performed by hand force applied to a knob 36 provided at the center of the back plate 38 of the holder frame 102.

A device allowing relative horizontal movement of the holder 20 is shown in FIG. This is a pair of inwardly directed flanges 40 and 42 which in this example are the first part of the second attachment device.
, which are secured to the front frame 44 of the cassette holder 20 by suitable devices such as screws 46. Flanges 40 and 42 are engaged and slidable along rails 48 and 50. rail 4
8 and 50 form the outer edge of a first light shielding plate 52, which is fixed relative to the aperture 30 in its horizontal position. An opening 54 is provided in plate 52 and is shown in dashed lines in FIG. This aperture has approximately the same width as aperture 30, but is substantially longer. This accommodates the movement of the cassette. In this example, the first part of the first mounting device is the gobo plate 66, and the second part of the first mounting device is constituted by the pair of inward flanges 56, 58 and the gobo plate 52; and 58 are fixedly mounted adjacent the innermost ends 60 and 62 of the opening 54 in the plate 52. This installation is done using the screw 64 shown in Figure 4.
This is done using a suitable device such as. Flange 5

The clip 112 can be reattached using a screw 118 that engages with a hole 120 (FIG. 1) provided for this purpose.

The cassette 34 is inserted into the frame 102, and the film protector 122 transfers the film 32 to the camera 22.
Once removed to expose the cassette 34, the remaining task is to properly position the cassette 34 and continue recording the desired image. In FIG. 5, the normal position of the image, in which six images are recorded, is indicated by a dashed outline.

Figures 6-11 schematically illustrate how images are recorded and the relative positions of plates 52 and 66 during image recording. FIG. 6 shows the normal position of the film cassette relative to plates 52 and 66 when the first image is recorded. This position is obtained by moving knob 36 in the direction indicated by arrow 123. As shown in FIG. 7, knob 36 is then moved in the direction of arrow 124 to expose a second image disposed horizontally from the first image. In FIG. 8, the knob 36 is indicated by arrow 1.
