Definitions

  • the information carrier is wound on a reel which is contained fixing surfaces of any cartridge of said first type so as to hold said cartridge of said first type in an operative position on said appliance, second locating and fixing means adapted to engage said locating and fixing surfaces of any cartridge of said second type so as to hold said cartridge of said second type in an operative position on said appliance, threading means operable to mechanically move said leading end of said information carrier in a cartridge of either of said first and second types when said cartridge is held in said operative position, first reel-driving means adapted to cooperate with said flange and operable to drive said reel in a cartridge of said first type when said cartridge is in said operative position, and second reel-driving means comprising a mandrel adapted to extend through said aperture into engagement with said bore of a reel of a cartridge of said second type when said cartridge is in said operative position.
  • the second reel-driving means are operable to drive said reel in said cartridge of said second type.
  • Various types of cartridges have already been proposed for use with motion-picture projectors for substandard film.
  • the cartridges choose one of these types of cartridges. For a user of a projector, this means'that' he can use only cartridges of that type for which the projector is designed.
  • a user of a projector either cannot project films, e.g., rented films, which are supplied in cartridges for which his projector is not designed, or he must procure another projector designed for use with cartridges of a second type.
  • This is a serious disadvantage for the users of substandard film projectors.
  • the reduction-of the numbers in which a given projector is sold increases the cost thereof.
  • the same remarks are applicable to appliances which may be alternatively used .to record on or reproduce from magnetic tape. Numerous types of cartridges have already been proposed for such magnetic tape-handling appliances. It is an object of the invention to eliminate these disadvantages and to provide an appliance in which cartridges of different types can be used.
  • the invention relates to an appliance for recording and/or reproducing information, particularly a motion picture projector for substandard film, which appliance is adapted to be loaded with cartridges whichcontain a striplike record carrier on a supply reel, and which appliance is provided with locating and/or fixing.
  • the appliance comprises at least one additional locating and/or fixing means for locating and/or fixing cartridges of a different type, which havelocatingand/or fixing surfaces differing from those of the first-mentioned cartridge, additional drive means for driving the supply reel are provided, one of the drive means cooperates in known manner with a flange of the supply reel whereas the other drive means comprise a mandrel, which is adapted to be introduced in known manner through an opening in the cartridge wall into a central bore of the supply reel, and preferably the striplike record carriers which have been moved through exit openings out of a cartridge of any of the different types are adapted to be guided to common guiding means and recording and/or reproducing means.
  • the arrangement may be such that the means which are associated with cartridges of the different types, at least the fixing means, are mounted on respective attachments for the appliance, one of which attachments is detachably connected to a base structure which comprises at least part of the transmission.
  • the requirements of the user can easily be met in that the attachment desired by the buyer is mounted on the base structure of the appliance.
  • the base structure may be made in large numbers so that the cost of the appliance is reduced. If the buyer of an appliance intends to use cartridges of different types, he need no longer procure two different appliances but it will be sufficient for him-to have different attachments for use with a single base structure'
  • the appliance may be integral and be designed so that cartridges of different types may be fixed to the appliance in one and the same area and the drive means for use with cartridges of a given type are adapted to be removed when a cartridge of another type is to be used.
  • the cartridge may be relatively small.
  • a difficulty may arise because the threading device is not always aligned with the exit opening of the cartridge or the center of the reel in the cartridge where cartridges of difierent type are used.
  • These difiiculties may be eliminated within the scope of the invention in that the fixing means are so arranged that. the centers of the reels having different capacities are substantially disposed on one and the same line regardless of the type of cartridge which is used. In this connection, the centers of the reels need not actually be disposed on one line, provided that they are substantially disposed thereon.
  • the abovementioned difficulty may alternatively be avoided in that the appliance is provided with sensing meansfor detecting the type of cartridge fixed to the appliance.
  • the sensing means may control a displaceable carriage, on which the threading device is mounted and which is arranged to-be controlled in response to the type of cartridge detected by the sensing means so that the threading means is always aligned with the exit opening of the cartridge.
  • the pivot of the lever is adjustable to at least two positions, one of which represents an optimum for cartridges of a first type and the other an optimum for cartridges of a second type.
  • the means for locating cartridges of different types will generally have to be different. These locating means may comprise apertures or projections, which are provided on the cartridge and which cooperate with complementary elements provided on the appliance. Because cartridges of different types have substantially the same main dimensions, the locating means are provided on the appliance generally in the same area and a cartridge of a given type to be mounted on the appliance may interfere with the means for locating cartridges of the second type. To eliminate these difiiculties, it is a feature of the invention that the means for locating cartridges of a first type are rigid in the direction in which cartridges of said type are applied to the appliance and are movable in the direction in which cartridges of the second type are applied to the appliance.
  • the appliance may be designed to have cartridges of different type mounted thereon in different areas and be provided in each of said areas with fixing means and drive means for cartridges of the associated type.
  • This arrangement will eliminate the difficulties which are due to the provision of different drive means in a single area.
  • different recording and/or reproducing means may be associated with different areas for fixing cartridges.
  • a motion picture projector according to the invention is provided with means for guiding the film to a common lens from the different areas.
  • the guide means mayguide the magnetic tape from the different areas to common recording and reproducing means.
  • Appliances having means for threading the strip may be provided with a threading device in each area which is associated with cartridges of a given type. This feature will contribute to a clear and relatively simple structure of the appliance.
  • the threading means may be common to cartridges of different types and may be movable to positions adjacent to cartridges fixed in different areas.
  • a single threading device may be used for cartridges of all types, provided that this single threading device is designed for use with cartridges of all types which are contemplated.
  • a feature of the invention to provide for a removal of the leading end of the film from the roll a device which comprises movable film-guiding elements, which are movable into the cartridge and which close free openings which exist between the cartridge wall and the threading device which has been moved into the cartridge.

  • Cartridges 2, 3 of different type can be fixed to a motion picture projector l for substandard film.
  • a threading device 4 is movable into the exit opening of cartridge 2 or cartridge 3.
  • the cartridges 2, 3 differ not only in external configuration.
  • Cartridge 2 is provided in one end wall with an opening, not shown, through which a friction wheel 5 may be entered, which is mounted on a lever 6 that is pivoted on a pivot 7.
  • the friction wheel 5 is adapted to be driven by means which are not shown and serves to drive the supply reel in the cartridge 2. For this purpose, the friction wheel engages an end flange of said reel.
  • the cartridges 3 are not provided with such opening in an end wall but adjacent to the center 8 of the supply reel in such cartridge have an aperture through which a reel mandrel can extend, which is mounted on the projector l.
  • the center 10 of the reel in the cartridge 2 is not adjacent to the reel mandrel 9 and the cartridge 2 has no aperture for receiving the reel mandrel 9. It will be understood that for the use of cartridges 2 the reel mandrel 9 must be removed from the area of the cartridge whereas the friction wheel 5 must be swung out where cartridges 3 are to be used. These remarks will also be applicable if film reels not accommodated in cartridges are to be used instead of the cartridges 3. It will be understood that the illustrated projector 1 may be used with cartridges 2, 3 as well as with reels which are not accommodated in cartridges.
  • FIG. 2 illustrates an arrangement for a mutual control of the respective drive means.
  • the reel mandrel 9 is mounted on a reel-carrying arm 11, which is pivoted on a pivot 12, to which a cam 13 is fixed.
  • the cam 13 is operatively connected by a tension spring 14 to a push rod 15, which is guided by a pinslot arrangement.
  • the push rod 15 is provided at its end with a stop 16.
  • the stop 16 is in register with a complementary stop 17 carried by the pivoted arm 6 for the friction wheel 5 or releases said stop 17.
  • a compression spring 18 urges the pivoted arm 6 against a pin 20, which extends through a slot 19 of the pivoted arm 6.
  • the pin 20 is secured to an actuating rod 21, by which the pivoted arm 6 can be released and moved to its operative position.
  • the reel-carrying arm 11 In the position shown, the reel-carrying arm 11 is in position of rest and the push rod 15 is in its right-hand position, in which the stops 16, 17 are out of register so that the friction wheel 5 can be swung into a cartridge 2a.
  • the reel mandrel 9 is required to drive the supply reel in such cartridge.
  • the reel-carrying arm 11 is swung in the counterclockwise sense and the cartridge 3 or 3a is mounted on the reel mandrel 9.
  • the cam 13 displaces the push rod 115 to the left so that the stop 16 is in register with the stop 17 and the friction wheel 5 cannot be pivotally moved even when it has been released by the actuating rod 21.
  • FIG. 2 shows also the centers 8, 8a and 8b of cartridges which differ in size and are of a type which is similar to cartridges 3 and 3a.
  • the centers 8, 8a, 8b are disposed on a sector 22 of a circle, which has a radius which is equal to the distance between the centers of the pivot 12 and the reel mandrel 9.
  • the centers 10, 10a, 10b, and of reels accommodated in cartridges which are similar to cartridges 2, 2a lie on a straight line 23.
  • the sector 22 and the line 23 are selected so that the centers of the reels differing in capacity lie virtually on a single line for cartridges of each of the types which are used and are only slightly spaced from said line. This arrangement will ensure that the threading device 4 is always in register with the exit opening of the cartridge regardless of the type and size thereof.
  • FIG. 3 shows different means for disabling the friction wheel 5.
  • a sensor 25 detects apertures 24 of the cartridges 3.
  • the sensor 25 comprises a sensing pin 26, which is disposed adjacent to the apertures 24 and secured to an arm 28, which is pivoted on a pin 27 and constantly biased by a spring.
  • arm 28 carries a locking pin 30, which in the inoperative posi-v tion of the arm 28 extends into the path of the pivoted arm 6 for the friction wheel 5.
  • the cartridge 2 will depress the sensing pin 26 to move the locking pin 30 out of the path of the pivoted arm 6 so that the latter can be swung in by means of the actuating rod 21.
  • the sensing pin 26 will enter aperture 24 and the locking pin 30 will remain in the path of the pivoted arm 6 to lock the same. It will then be impossible to impart a pivotal movement to the arm 6 even by an erroneous operation of the actuating rod 21.
  • the centers 8, 8a, 8b or 10 to 100 are disposed substantially on a single line to ensure that the threading device 4 is always in register with the exit opening of the cartridge which is used.
  • FIGS. 4 and 5 A different arrangement for the same purpose is shown in FIGS. 4 and 5.
  • Cartridges 2, 2a and 3, 3a are secured to the projector in such a position that the lower right comer of each cartridge is disposed at the same point. As a result, the centers of the exit openings disposed on the underside of the cartridge will be in-
