Definitions
- This invention relates to apparatus for unloading cassettes of the type that contain X-ray film.
- cassettes commonly used to hold a large sheet of X-ray film for recording a chest X-ray image or the like, includes a pair of walls pivotally connected at one end and latchable at the opposite end, which hold a film sheet between them.
- Such cassettes permit an undeveloped film sheet to be handled in a daylight environment, as when bringing the film to a chest X-ray unit for exposure or when carrying the exposed film to a processor.
- an unloader for an X-ray film-holding cassette, which can open the cassette to allow the film to fall into processing apparatus, utilizing a relatively simple and reliable mechanism.
- the unloader includes a lighttight housing with guides that slidably receive.a cassette, and with release pins at the end of the space between the guides for engaging corresponding latches on the cassette to open it.
- the guides extend at an incline from the vertical, so that the cassette tends to swing widely open when unlatched, and the film will then drop out.
- the housing includes an upper opening, through which the cassette is received, and a cover that can be pivoted over the opening.
- a spring biased retainer member holds the cassette slightly above the pins, to prevent opening of the cassette while the cover is open. As the cover is swung closed, it pushes down against the cassette to engage the pins, so that the cassette opens only when the housing is substantially sealed from light in the environment.
- a plurality of guides are provided for receiving cassettes of different sizes. The pins at the ends of the different guides are positioned so that the upper end of. the cassette lies slightly above the door level when the bottom of the cassette is close to the pins, so that closing of the door will push down and cause unlatching of the cassette held by any of the guides.
- Fig. 1 illustrates a cassette unloader 10 which can receive a cassette 12, wherein the cassette is closed and contains a sheet of exposed X-ray film.
- the unloader can open the cassette while holding it at an incline from the vertical, to allow the film therein to fall out, and can funnel the film to a processing apparatus 14, all without exposing the film to light in spite of the unloader lying in a daylight environment.
- the unloader 10 includes a lighttight housing 16 with a bottom that rests on apparatus 14 and a top forming an opening 20 through which cassettes are received. After a cassette has been received, a cover 22 can be closed to make the housing lighttight.
- a group of guide assemblies 24, 26 and 28 are provided for receiving cassettes of different sizes.
- the particular cassette 12 is designed to be received between a pair of guides 30 of the guide assembly 28.
- the cassette 12 includes a pair of walls-31, 32 that are pivotally joined at one end 34 of the cassette and which are latched together at an opposite end 36 of the cassette.
- the base wall 31 includes a peripheral lip 38 that surrounds the covering wall 32 when the cassette is closed.
- Wall 32 includes a pair of latches 40 that are spring biased so that their ends 42 tend to project from the wall and through corresponding holes 44 in the lip 38 of the base wall, when the cassette is closed.
- the latches 40 can, however, be retracted to withdraw their ends 42, for opening or closing of the cassette.
- the unloader 10 is constructed to automatically operate the latches to open the cassette after it is inserted in the unloader.
- the cassette 12 When the cassette 12 is inserted between the guides 30, as indicated in Figs. 1 and 5, the cassette moves down until it encounters a springloaded retainer 46 which lies on a bar 48 at the lower end of the space between the guides 30. When downward force is applied to the cassette, it presses down the retainer 46 against the force of a spring 50, so that the cassette can approach and engage a pair of release members or pins 52.
- the pins 52 are located so that they will fit into the holes 44 (Fig. 2) of the cassette to push against the ends 42 of the cassette latches. Thus, as the cassette is forced down, the pins 52 force the retraction of the latches to release the wall 32.
- a pair of leaf springs 54 are located within the cassette to initially push apart the walls to begin the opening of the cassette. The leaf springs 54 also lie behind the lower edge of the film, so they push out the lower film edge as the cassette opens.
- the guides 30 are inclined by an angle A from the vertical. As a result, when the cassette latches are released and the cover wall 32 of the cassette moves slightly open, gravity pulls the cover wall 32 to a more open position. With the cassette considerably opened and oriented at an incline so the film 56 faces partially downward, the film 56 (whose lower edge is pushed out by the leaf springs in the cassette) is able to fall out of the cassette and into the processor apparatus located below a funnel 58. It may be noted that the cassette must be inserted so that the cover wall 32 faces ' downwardly. As shown in Figs. 5 and 6, the guides 30 have shallow grooves 30r so that they hold only the lip 38 of the base wall of the cassette, but not the cover wall 32. Thus, the cover wall 32 is free to swing open when unlatched.
- the cassette When the cassette is initially inserted through the opening 20 at the top of the unloader housing, the cassette is exposed to light entering through the opening 20. It is important-that the cover 22 be closed sufficiently to keep out light, at the time when the cassette is unlatched to open, and it is desirable that the cassette then open automatically. To accomplish this, the cover 22 is utilized in the manner illustrated in Figs. 3 and 4, to push down the cassette, and to open it immediately after the door is moved to a position wherein it closes sufficiently to keep out light. As discussed above, the inserted cassette initially rests on the retainer 46. When the cassette rests on the retainer 46, as in Fig. 3, its upper end 34 projects into the path of the cover 22.
- the cover 22 lying lightly on the upper end of the cassette, it is sufficiently closed to prevent the entrance of light into the unloader, but the opening 20 is not yet fully closed.
- the technician can fully close the opening by applying downward force to the cover, until holder members 60 on the cover engage catches 62 on the side walls of the housing to keep the cover fully. closed. While the cover is being fully closed, it pushes down the cassette 12 against the biasing of retainer 46, until the cassette latches engage the pins 52 at the bottom of the space between the guides -30. The pins 52 then depress the latch ends of the cassette, to cause opening of the cassette and release of the X-ray film.
- the unloader includes two guide assemblies 24, 26 (Fig. 1), in addition to'the guide assembly 28 with guides 30, to enable. the unloading of two other sizes of cassettes.
- the other two cassette sizes are of smaller length and narrower width than the cassette 12. Accordingly, the pair of guides 64 and'66 of each of the other guide assemblies are closer together, and the lower bars 68, 70 are at a greater height than the lower bar 48 which holds the retainer 46 and the pins 52.
- the other bars 68, 70 hold corresponding pins and retainers, at levels such that when cassettes of corresponding sizes are first inserted, and lie on their respective spring- biased retainers, their upper ends lie in the path of the cover 22. Accordingly, full closure of the cover will push down and cause opening of cassettes of any one of the three sizes provided for.
- the funnel 58 is made wide enough to receive films dropping from any of the three guide assemblies.
- side funnel plates 72 are provided to engage the sides of films to enable their passage through the funnel 58, and that a processor such as 14a, designed to receive a small film sheet from a small cassette, may be provided with additional side funnel plates 74 to accurately guide these small sheets into the corresponding processor.
- release pins or members 52 fixed in position and of the housing cover 22 to press the pins into a cassette provides a simple mechanism
- the pins can be movably mounted, and moved against the cassette by a mechanism controlled from outside the housing or by a mechanism that operates after the cover is fully closed on the housing.
- side funnel plates. 72 (Fig. 1) can engage the sides of films dropping towards the funnel 58. These plates prevent tumbling of large films exiting from large cassettes on the guide assembly 28.
- two pairs of edge guides 80, 82 are provided in order to prevent tumbling of films exiting from smaller cassettes on the guide assemblies 24, 26, two pairs of edge guides 80, 82 are provided.
- the pair of edge guides 82 are pivotally mounted on the outside of grooved guides 6.4 of the guide assembly 26. These edge guides can guide the edges of a film exiting from a cassette on the guides 64.
- the edge guides 82 In order to allow the edge guides 82 to effectively guide a film, the edge guides 82 must extend through the space between the cassette guides 30, as shown in Fig. 3. The edge- guides 82 tend to assume this position when free to pivot thereto by gravity. When a large cassette 12 is received between the guides 30, as shown in Fig. 4, the large cassette will deflect the edge guides 82 out of the way of the cassette, and out of the way of a film 56 falling from the cassette. In a similar manner the edge guides 80 (Fig. 1) lying beside the smallest guide assembly 24, will be deflected by a medium cassette on guide assembly 26, and will be partially deflected by a large cassette on guide assembly 26. It may be noted that the edge guides 80 have slots 86 to avoid engagement with bar 68 on the guide assembly 26.
- the invention provides'a relatively simple apparatus for removing a sheet of X-ray film from a cassette by an operator located in a daylight environment. This is accomplished by utilizing a lighttight housing with guide means for receiving the cassette in the housing and with pins, or release members, positioned in the housing to engage the latches on the cassette to release them when the cassette has been inserted into-the housing. Closing of the housing to make it lighttight, and also to aid in pushing in the cassette against the release pins, is enabled by the use of a cover. The cover moves close enough to its fully closed position to keep the housing lighttight at a time when it pushes the cassette against the release pins, so that the cassette.opens in a dark environment.
- a biased retainer holds the cassette from fully engaging the pins until pushed down by the cover.
- the guides hold the cover at an incline, so that once it is unlatched it swings open to allow the film to drop out therefrom and into a funnel leading to processing apparatus.
- a series of closely spaced guides can be utilized to hold cassettes of a plurality of different sizes in a compact unloader. The guides can be positioned so that each cassette size is pushed against its respective release pin by the cover approaching its fully closed position. Film edge guides can be provided that guide the exiting film through the space at which larger cassettes can be received, and with the edge guides being deflectable out of the way by the larger cassettes.

Abstract
Description
- This invention relates to apparatus for unloading cassettes of the type that contain X-ray film.
- One type of cassette, commonly used to hold a large sheet of X-ray film for recording a chest X-ray image or the like, includes a pair of walls pivotally connected at one end and latchable at the opposite end, which hold a film sheet between them. Such cassettes permit an undeveloped film sheet to be handled in a daylight environment, as when bringing the film to a chest X-ray unit for exposure or when carrying the exposed film to a processor.
- Although the use of a cassette has facilitated movement of the undeveloped film, it has usually been necessary to carry the cassette containing the exposed film to a darkroom for removal and placement of the film in a processing machine which develops it. It would be possible to devise complex unloader mechanisms for opening the cassette and transferring the film to a processor while an operator of the mechanism stands in a daylight environment. However, in order for a film unloader to gain wide acceptance,'it is necessary that it be relatively simple, to minimize the cost and maximize the reliability of the device. It would also be desirable if any such device could accept cassettes of a plurality of different sizes without requiring it to have a substantially increased size or complexity.
- In accordance with one embodiment of the present invention, an unloader is provided for an X-ray film-holding cassette, which can open the cassette to allow the film to fall into processing apparatus, utilizing a relatively simple and reliable mechanism. The unloader includes a lighttight housing with guides that slidably receive.a cassette, and with release pins at the end of the space between the guides for engaging corresponding latches on the cassette to open it. The guides extend at an incline from the vertical, so that the cassette tends to swing widely open when unlatched, and the film will then drop out.
- The housing includes an upper opening, through which the cassette is received, and a cover that can be pivoted over the opening. A spring biased retainer member holds the cassette slightly above the pins, to prevent opening of the cassette while the cover is open. As the cover is swung closed, it pushes down against the cassette to engage the pins, so that the cassette opens only when the housing is substantially sealed from light in the environment. A plurality of guides are provided for receiving cassettes of different sizes. The pins at the ends of the different guides are positioned so that the upper end of. the cassette lies slightly above the door level when the bottom of the cassette is close to the pins, so that closing of the door will push down and cause unlatching of the cassette held by any of the guides.

- Fig. 1 illustrates a
cassette unloader 10 which can receive acassette 12, wherein the cassette is closed and contains a sheet of exposed X-ray film. The unloader can open the cassette while holding it at an incline from the vertical, to allow the film therein to fall out, and can funnel the film to aprocessing apparatus 14, all without exposing the film to light in spite of the unloader lying in a daylight environment. - The
unloader 10 includes alighttight housing 16 with a bottom that rests onapparatus 14 and a top forming anopening 20 through which cassettes are received. After a cassette has been received, acover 22 can be closed to make the housing lighttight. A group of guide assemblies 24, 26 and 28 are provided for receiving cassettes of different sizes. Theparticular cassette 12 is designed to be received between a pair ofguides 30 of theguide assembly 28. - The
cassette 12 includes a pair of walls-31, 32 that are pivotally joined at oneend 34 of the cassette and which are latched together at anopposite end 36 of the cassette. As shown in greater detail in Fig. 2, thebase wall 31 includes aperipheral lip 38 that surrounds thecovering wall 32 when the cassette is closed.Wall 32 includes a pair oflatches 40 that are spring biased so that theirends 42 tend to project from the wall and throughcorresponding holes 44 in thelip 38 of the base wall, when the cassette is closed. Thelatches 40 can, however, be retracted to withdraw theirends 42, for opening or closing of the cassette. Theunloader 10 is constructed to automatically operate the latches to open the cassette after it is inserted in the unloader. - When the
cassette 12 is inserted between theguides 30, as indicated in Figs. 1 and 5, the cassette moves down until it encounters a springloadedretainer 46 which lies on abar 48 at the lower end of the space between theguides 30. When downward force is applied to the cassette, it presses down theretainer 46 against the force of aspring 50, so that the cassette can approach and engage a pair of release members orpins 52. - The
pins 52 are located so that they will fit into the holes 44 (Fig. 2) of the cassette to push against theends 42 of the cassette latches. Thus, as the cassette is forced down, thepins 52 force the retraction of the latches to release thewall 32. A pair ofleaf springs 54 are located within the cassette to initially push apart the walls to begin the opening of the cassette. Theleaf springs 54 also lie behind the lower edge of the film, so they push out the lower film edge as the cassette opens. - As shown in Fig. 4, the
guides 30 are inclined by an angle A from the vertical. As a result, when the cassette latches are released and thecover wall 32 of the cassette moves slightly open, gravity pulls thecover wall 32 to a more open position. With the cassette considerably opened and oriented at an incline so thefilm 56 faces partially downward, the film 56 (whose lower edge is pushed out by the leaf springs in the cassette) is able to fall out of the cassette and into the processor apparatus located below afunnel 58. It may be noted that the cassette must be inserted so that thecover wall 32 faces 'downwardly. As shown in Figs. 5 and 6, theguides 30 have shallow grooves 30r so that they hold only thelip 38 of the base wall of the cassette, but not thecover wall 32. Thus, thecover wall 32 is free to swing open when unlatched. - When the cassette is initially inserted through the
opening 20 at the top of the unloader housing, the cassette is exposed to light entering through theopening 20. It is important-that thecover 22 be closed sufficiently to keep out light, at the time when the cassette is unlatched to open, and it is desirable that the cassette then open automatically. To accomplish this, thecover 22 is utilized in the manner illustrated in Figs. 3 and 4, to push down the cassette, and to open it immediately after the door is moved to a position wherein it closes sufficiently to keep out light. As discussed above, the inserted cassette initially rests on theretainer 46. When the cassette rests on theretainer 46, as in Fig. 3, itsupper end 34 projects into the path of thecover 22. With thecover 22 lying lightly on the upper end of the cassette, it is sufficiently closed to prevent the entrance of light into the unloader, but theopening 20 is not yet fully closed. The technician can fully close the opening by applying downward force to the cover, untilholder members 60 on the cover engagecatches 62 on the side walls of the housing to keep the cover fully. closed. While the cover is being fully closed, it pushes down thecassette 12 against the biasing ofretainer 46, until the cassette latches engage thepins 52 at the bottom of the space between the guides -30. Thepins 52 then depress the latch ends of the cassette, to cause opening of the cassette and release of the X-ray film. - As mentioned above, the unloader includes two
guide assemblies 24, 26 (Fig. 1), in addition to'theguide assembly 28 withguides 30, to enable. the unloading of two other sizes of cassettes. - The other two cassette sizes are of smaller length and narrower width than the
cassette 12. Accordingly, the pair ofguides 64 and'66 of each of the other guide assemblies are closer together, and thelower bars lower bar 48 which holds theretainer 46 and thepins 52. The other bars 68, 70 hold corresponding pins and retainers, at levels such that when cassettes of corresponding sizes are first inserted, and lie on their respective spring- biased retainers, their upper ends lie in the path of thecover 22. Accordingly, full closure of the cover will push down and cause opening of cassettes of any one of the three sizes provided for. Thefunnel 58 is made wide enough to receive films dropping from any of the three guide assemblies. It also may be noted thatside funnel plates 72 are provided to engage the sides of films to enable their passage through thefunnel 58, and that a processor such as 14a, designed to receive a small film sheet from a small cassette, may be provided with additionalside funnel plates 74 to accurately guide these small sheets into the corresponding processor. - Although the use of release pins or
members 52 fixed in position and of thehousing cover 22 to press the pins into a cassette provides a simple mechanism, other arrangements can*be utilized. For example, the pins can be movably mounted, and moved against the cassette by a mechanism controlled from outside the housing or by a mechanism that operates after the cover is fully closed on the housing. - As mentioned above, side funnel plates. 72 (Fig. 1) can engage the sides of films dropping towards the
funnel 58. These plates prevent tumbling of large films exiting from large cassettes on theguide assembly 28. In order to prevent tumbling of films exiting from smaller cassettes on theguide assemblies guide assembly 26. These edge guides can guide the edges of a film exiting from a cassette on theguides 64. - In order to allow the edge guides 82 to effectively guide a film, the edge guides 82 must extend through the space between the cassette guides 30, as shown in Fig. 3. The edge-
guides 82 tend to assume this position when free to pivot thereto by gravity. When alarge cassette 12 is received between theguides 30, as shown in Fig. 4, the large cassette will deflect the edge guides 82 out of the way of the cassette, and out of the way of afilm 56 falling from the cassette. In a similar manner the edge guides 80 (Fig. 1) lying beside thesmallest guide assembly 24, will be deflected by a medium cassette onguide assembly 26, and will be partially deflected by a large cassette onguide assembly 26. It may be noted that the edge guides 80 haveslots 86 to avoid engagement withbar 68 on theguide assembly 26. - Thus, the invention provides'a relatively simple apparatus for removing a sheet of X-ray film from a cassette by an operator located in a daylight environment. This is accomplished by utilizing a lighttight housing with guide means for receiving the cassette in the housing and with pins, or release members, positioned in the housing to engage the latches on the cassette to release them when the cassette has been inserted into-the housing. Closing of the housing to make it lighttight, and also to aid in pushing in the cassette against the release pins, is enabled by the use of a cover. The cover moves close enough to its fully closed position to keep the housing lighttight at a time when it pushes the cassette against the release pins, so that the cassette.opens in a dark environment. A biased retainer holds the cassette from fully engaging the pins until pushed down by the cover. The guides hold the cover at an incline, so that once it is unlatched it swings open to allow the film to drop out therefrom and into a funnel leading to processing apparatus. A series of closely spaced guides can be utilized to hold cassettes of a plurality of different sizes in a compact unloader. The guides can be positioned so that each cassette size is pushed against its respective release pin by the cover approaching its fully closed position. Film edge guides can be provided that guide the exiting film through the space at which larger cassettes can be received, and with the edge guides being deflectable out of the way by the larger cassettes.
