According to the present invention, also be provided with a film driver control system on the camera 5, it is made up of a film driver actuating device 85 and a film driver reversing arrangement 90.When camera 5 is the beverage can shape, the actuating device 85 of film driver is similar to the top cover of beverage can, the reversing arrangement of film driver then is in the actuating device 85, in first embodiment, it can be used as one and is in the reversing arrangement actuation element 93 in the beverage can tab profile line and extends.
Film driver actuating device 85 can be on the direction shown in the arrow (Fig. 5 a, 6a, 9a and 9b) move two-wayly, its moving on first direction can cause the film driver to move along the direction that film advances, and its moving on second direction then causes the film driver to move along the direction that film rewinds.As can be seen, the actuating device of film driver is round from above-mentioned each accompanying drawing, and it rotates widdershins film is advanced, and it deasil rotates and makes film rewind (vice versa).Certainly, the profile of the actuating device of film driver needs not to be round, but still should be rotary, so that such and film driver synergy as mentioned below.
Film driver reversing arrangement 90 can move on two positions.Primary importance is the state that film advances, that is, allow film driver actuating device 85 to move (so that film advances) along first direction, rather than move along second direction (rewinding), thereby when also having film can continue exposure, can prevent that film from unexpectedly rewinding.The second place is the state that film rewinds, that is, allow film actuating device 85 to move (so that film rewinds) along second direction, rather than move along first direction (advancing), thereby when film rewinds, can prevent that film from unexpectedly advancing.
When film 58 had been rewinded, available one is adorning spool box new, unexposed film replaced spool box 57.Then, must reset the reversing arrangement 90 of film driver, that is, or mechanically insert new film, or film reversing arrangement 90 is dialled back the state that film advances again with hand.
Thereby film driver reversing arrangement can carry out work in a kind of mode of safety locking, guarantees that the film driver can only move on a selected direction.
Film driver reversing arrangement 90 can be any structure that is suitable for the special hull shape that camera adopts.When camera shell 10 is the beverage can shape, can be beverage can draw ring shape (referring to the actuation of the switch element 93 of Fig. 3-6c) for reversing arrangement 90 is provided with one.When reversing arrangement actuation element or draw ring 93 flush (Fig. 3 with " beverage can ", 5b and 5c) time, reversing arrangement is to be in the film forward travel state, pass through around centring point 105 (referring to Fig. 4 and work as draw ring 93,6b and 6c) pivot and when being drawn out the plane, place of top cover 100 of " beverage can ", reversing arrangement 90 converts film to and rewinds state (vice versa).Disposing like this helps allow camera be similar to a beverage can generally.Similarly, as Fig. 1,7a, 7b, shown in 8a and the 8b, the reversing arrangement driving element can be a button, this button can be in the same plane of " beverage can " top cover 100 move left and right (in the outline line scope of beverage can draw ring).
Above-mentioned only is is applicable to two examples in numerous shapes, size and the mobile status of the present invention's the film reversing arrangement of control system of artificial film driver and attached reversing arrangement actuating device.For example, can adopt a push button reversing arrangement, or can advancing and rewind between the state conversion or the reversing arrangement of the circle that rotates at film.
Therefore, the reversing arrangement of the commutation actuating device of film and film driver can be any shape that is adapted to camera shell 10 designs.For example, camera shell can be the jar shape, and film driver actuating device is similar to the lid of container, and reversing arrangement then is similar to the safety switch of opening usefulness.Perhaps, camera shell can be the bottle shape, and film driver actuating device is similar to the neck of bottle, and reversing arrangement then is similar to bottle cap etc.In fact, housing is not necessarily columniform, it can be an Any shape, even can be the shape of a rag baby or toy animals, rotate certain part (for example head or arm) of doll or animal health, just can activate the film driver, and the actuation element of reversing arrangement can be doll or Animal Tails, eyes or face.
In the embodiment shown in Fig. 5 a-5c and the 6a-6c, illustrated that a film driver reversing arrangement 90 of the present invention and film driver actuating device 85 are how to form film driver control of the present invention system with a film driver collaborative work.Film driver actuating device 85 comprises a gear 110, and the tooth of this gear is meshed with the tooth of first gear 115 of film driver gear group 120 (also referring to Fig. 9 a and Fig. 9 b).Therefore, the rotation of film driver actuating device 85 can the well-known technology in mat present technique field, makes first gear 115, and then is that whole gear set rotates.Film driver actuating device 85 also comprises a toothed ratchet 125, its tooth 138 and 90 engagements of film driver reversing arrangement.
Better suited is that for film driver reversing arrangement 90 is provided with a pair of ratchet or elastic arm 130,135, they are connected in a pivotal pin 137 that extends from " beverage can " top cover 100, and can rotate around it.This two ratchet is by extending from reversing arrangement actuation element 93, driving with one of ratchet 130,135 or a engaged element 140 that both are meshed.In first embodiment shown in Fig. 5 b and Fig. 6 b, this engaged element also meshes with a stopping element 143, and this stopping element gives the reversing arrangement effect of " card is joined " in a well-known manner.
When reversing arrangement was in the film forward travel state, first ratchet 130 operably meshed with the tooth 138 (at Fig. 5 b, 6b only shows a part among 7a and the 8a, extends but be actually around ratchet) of ratchet 125.In this state, ratchet 130 can allow the film driver 85 of actuating devices in one direction, just (direction " C " among Fig. 5 b and Fig. 7 a) moves on the film working direction.When reversing arrangement is in film and rewinds state (Fig. 6 a, 6b, 6c, 8a and 8b), the tooth 138 of second ratchet and ratchet 125 operably meshes.In this state, ratchet 135 can allow the film driver 85 of actuating devices in one direction, just (direction among Fig. 6 b and the 8a " D ") moves on the direction that film rewinds.
At Fig. 3,4 and 5a-6c shown in embodiment in, by promoting the reversing arrangement driving element, and then be its pivot that centers on pivotal point 105, can make ratchet engaged element 140 move to the position shown in Fig. 6 b and the 6c from the position shown in Fig. 5 b and the 5c, so just can the well-known mode in mat present technique field, make ratchet 130, in 135 one throw off with ratchet, and another and ratchet engaged.
Cooperating certainly with a lot of other methods of ratchet and ratchet controlled, and also can decide according to the type of the reversing arrangement actuation element that is adopted.At Fig. 7 a, among the 7b, 8a and 8b a ratchet control gear different with reversing arrangement actuation element among Fig. 1 has been shown, the configuration of so a kind of pawl-and-gearing is that the skilled person of the technical field of the invention is known.
Film driver reversing arrangement needn't be positioned on the driver actuating device, and it can be near film driver actuating device, concerted action with it again simultaneously.Under such a case, the tooth 138 of ratchet 125 can stretch out, and to admit the ratchet 130,135 of reversing arrangement 90, described reversing arrangement 90 extends from the reversing arrangement actuation element away from film driver actuating device.
Therefore, manual film driver control of the present invention system comprises: an aforesaid film driver actuating device 85 and a film reversing arrangement 90, they can be cooperated mutually with a film driver.Fig. 9 a and 9b have illustrated the function of a more suitable film driver.This film driver comprises a plurality of middle meshing gear that is in the gear set 120.Gear set 120 connects first and second film reels 50,55.Each gear in this gear set connects each other, and is connected in spool with a kind of like this state, that is, the rotation of a gear can make spool rotate along a single spool rotation direction in the gear set.Therefore, by first gear 115 in the gear set of film driver actuating device driven rotary two spools are rotated on a single spool rotation direction, film turns to according to the difference of spool and advances or rewind.
Film driver actuating device 85 can any traditional mode of mat prevent to surpass when film from advancing a lattice picture.In the embodiment shown in each accompanying drawing, particularly Figure 10 and 11, an arm spare 144 extands rearward to a shutter release lever 145 that is connected in shutter release button 43.When film advances a lattice picture, extand rearward to lever 145 arm spare 144 can by one be connected in sprocket wheel 60 standard lever system 150 and with film driver actuating device 85 (also can be referring to Fig. 5 a, 5c, 6a and 6c) on one second ratchet 148 keep separating state, but after the lattice picture that advanced, described lever system makes arm spare 144 and ratchet 148 engagements, prevents that it is advanced further.Then, must press shutter release button 43 discharging shutters, and arm spare 144 and ratchet 148 are thrown off, so just can allow film driver actuating device rotate again and make the film lattice that advance by release lever 160.Certainly, much other simple physical construction also can reach same effect, and described above only is an example of the system that uses of a kind of manual film driver control system that is suitable for the present invention.
