Definitions

  • This invention relates to receiving devices for image transmission in which the image is produced on a film moving along the recording device.
  • the image may be produced on the film, for example, by photographic means, the film for this purpose being provided with a photosensitive layer and scanned by a light beam, modulated by image signals, for example in parallel paths at right angles to the direction of movement of the film. Subsequently the exposed film is developed.
  • the marking device to be used may be adapted to operate automatically and to be controlled by a signal emitted at the transmitter side during the interval between the transmission of two successive images.
  • the mark is required to be provided, and it is in general not possible, for mechanical reasons, to arrange in addition a marking device in the said space. Since it is furthermore of paramount importanee that the film should pass along the scanning device at constant speed, it is not advisable to provide the marks at this area. Consequently, the mark is required to be provided outside the device for recording the image.
  • the marking device comprises, according to the invention, a first marking member which provides, under the action of the said signal, a mark in the film at an area which has already passed by the area at which the image is or will instantaneously be recorded, near the path of the film provision being made of a contact device which is operated when, during the movement of the film, the marked area passes the contact device.
  • the latter actuates a second marking member which provides a mark at that area of the film at which the recording of an image has started or ended.
  • the first mark may be indicated as a preliminary mark and the second as a definite mark.
  • the definite mark must be applied in such manner as to be not located in the path of the preliminary mark.
  • the definite mark may, for example, serve to control a cutting device for the film hand.
  • a cutting device for the film hand.
  • such a device may be actuated under the action of a second contact device provided near the path of the film and which responds when, during the further movement of the film, the area of the film marked by the second marking member passes the second contact device.
  • the device may be readily constructed in such manner that the film is invariably out between.
  • Fig. 1 shows the mechanical part of the apparatus according to the invention (all parts which are not essential to the invention being omitted).
  • Fig. 2 shows the electrical circuit-diagram.
  • designates a film on which the transmitted images are recorded in succession by photographic means.
  • This film is subsequently cut into definite parts of approximately equal length, which are conveyed to a developing device for photographic pictures (not shown). Since the dimensions of the recorded images in the direction of length of the film are not always the same and since, furthermore, the distances between successive images may vary, the portions cannot be of exactly the same length if it is desired to have the film invariably cut between two successive images. Consequently, according to the invention, Drovision is made of particular means whichensure that the cutting operation is invariably carried out between two successive images.
  • the unexposed film is drawn, with the use of means which will be described more fully hereinafter, from a drum 22, passes over a roller 23, passes by a scanning device 29 and moves on between pairs of rollers 24 and 25. Arranged between these pairs of rollers are the two marking devices P1 and P2 which, on becoming operative,
  • a contact device a2 arranged alongside the path of the film becomes operative when the marked part of the film passes by, for example, by means of a resiliently arranged membe slipping at that instant through the hole or the notch, thus closing a contact.
  • a similar contact member an is arranged beyond the pair of rollers 25.
  • the cutting device Sch which may comprise a pair of scissors 28.
  • the film is exposed at A.
  • a device 29 serves to move the modulated light beam in parallel paths at right angles to the film and for this purpose it is rotatable about a shaft parallel to the longitudinal direction of the film. Driving is ensured by an electric motor M.
  • the relay RLG becomes de-energized. so that the device P1 becomes operative with the result that, for xample, a hole is punched in the film.
  • this hole reaches the area of the contact member a2, a circuit is closed which comprises the winding of the punching member P2, so that a second hole or notch is formed in the film, pref erably, however, in a manner diiferent from the first, so that the two marks may be distinguished from one another.
  • the second mark is provided exactly at the beginning of each recorded image. Fhis is variably the case, even if the movement of the film is not quite uniform.
  • the said second marl: may thus serve to control a second contact member :11, which is included in a control circuit of the cutting device Sch.
  • each image would be cut off separately, since the signal which on ceasing actuates the punching member P1 is repeated after each image.
  • the transport must be stopped-if exactly before the cutting operation a film portion of about 50 cms. of length comprising no images has passed the point A, so that there are no further exposed images in the receiver, whereas the film transport must be resumed as soon as an image appears.
  • the shaft 3! of Fig. 1 is driven by the same electric motor M, which also serves to drive the scanning device.
  • the coupling 30 is an electrical coupling which becomes inoperative as soon as the winding K1 becomes conductive.
  • the film 2! is also moved onwards from the shaft 3
  • the said shaft 3! furthermore carries a driving wheel 35, which is coupled to one of the driving rollers 25. The movement by the rollers 25 is slightly more rapid than that by the rollers 24,
  • the shaft 3! has furthermore seated on it a cam disc the cam of which successively actuates the contact members '01, b2 and b3 when the disc turns.
  • the shaft 3! is furthermore coupled, through an electrical coupling 31, to a shaft 39, the latter being only driven by the shaft 31 when the wineing K2 of the coupling 3? is energized.
  • the shaft 39 can only be turned through a definite angle and returns, on being released, under the action of a spring 40 until it engages an abutment. It furthermore carries a cam disc 38, the cam of which actuates in succession contact members at and e when the shaft turns.
  • a voltage source which supplies the energising current for the punching and cutting members, for a number of relays R111 to RLs and RLv, for the windings K1 and K2 and for two pilot lamps L1 and L2.
  • the voltage of this source is, for example, 12 volts.
  • the contacts of the relays are designated by the same reference numerals as the windings thereof.
  • the numerals l to-2:'l of Figs. 1 and 2 have reference to identical points of contact in the circuit.
  • Fig. 2 also shows the contacts which are controlled in Fig. l, by the cam discs and the holes punched in thefilm.
  • a special signal is emitted, which, upon reception, produces at the receiver end, between the terminals IT and I8 of Fig. 2, a current which causes the relay RLs to respond.
  • this signal ceases and the relay RLG is de-ener gised, so that the contact of RLS reaches-the position shown in Fig. 2 and the punching device P1 is operated.
  • the arrangement may readily baconstructed in such manner that the punching member, after having punched a hole or a notch in the film, returns to its initial position, so that the movement of the film isnot hindered by the punching member.
  • the hole punched by P1 passes by the contact member as, which is then closed, so that the punching member P2 becomes operative and, furthermore, the relay RLs responds. Consequently, a second hole or notch is punchedin the film, preferably in the opposite margin, so that the contact member (12 does not respond when this second hole passes by the member as.
  • the cam disc 35 serves to ensure that invariably definite portions of the film of about 50 cms. of length are cut off since, when a lengthof film of about 50 cms. has been wound off, the camof the disc 35 has turned to such an extent that the contact In is closed.
  • the relay RLr is energized and retains its energy through the contact R-L1. Consequently, RL1 continues to be conductive till the relay RL3 responds and opens the circuit of RL1.
  • the response of RL1 moreover, initiates the closure of the circuits of K2, BL? and of Sch and RLs. When the next punching hole has arrived at or, the contact on is closed and K2 becomes energized.
  • the position of the contact d is chosen to be such that contact takes place exactly at the instant when the punched hole, which brought about the closure of a1, has arrived under the pair of scissors. Consequently, cutting oil cannot take place before the contact in is closed and about 50' cms. of film has passed by the pair of scissors.
  • the relay RLs is connected in parallel with the winding of Sch, so that, in addition, this relay responds and the relay RL1 is again de-energized. Consequently, the coupling 3! becomes interrupted and the disc 38 returns to its initial position.
  • the winding K1 invariably remains non-energized, so that the disc 35 continues rotating, thus at first contact member In and then b; becoming operative.
  • the former has no effect, since RLr has become deenergized.
  • the effect of the closure of be will be evident from the following.
  • the contact bi is closed and the relay RL1 responds, with the film having no marks, however, the contact or will not be closed.
  • the next operation depends upon the position of the relay RLz. If since the cutting of the film neither of the punches P1, P2 has been operative, this shows that there are no images on the film which is still in the receiver. The contact of RLs in the circuit of RLz is thus open and the relay RL2 is not energised. If, after in has been closed, the maximum length of image plus the distance between or and Sch has passed by, the contact member be is actuated.
  • the relay R114 which was energized through b2, R111 and 2, thus becomes interrupted, so that the contact RL4 arrives at the position shown and the winding K1 becomes energized.
  • the coupling 38 is then interrupted and the film transport stops.
  • the scissors Sch cut the film and the relay RLl becomes de-energised.
  • the contact In interrupts the circuit of RL2 once during each revolution of the shaft 3i thus de-energising RLz. Then RL2 becomes again energized by the next punching operation through the contacts of R115 and RLe and maintains itself in the energised position.
  • the contact e is a safety contact which stops the transport if the arrangement described should be disturbed.
  • the film transport After the film transport has been stopped by the contact be in the manner above described, it is resumed when the special signal ceases, which is emitted when no image signals proper are emitted.
  • the relay RLG is then de-energised again, so that the punching device P1 becomes operative. Subsequently, the relay RL2 is reenergised and then the relay RL4, which remains energized through its contact R114. Consequently, the film transport is resumed.
  • the relay RLz is de-energised immediately after the start of the film transport, since he is actuated immediately after b2.
