    • A one-time-use camera comprises a filmstrip having a certain width and a film leader for the filmstrip having another width that is greater than the width of the filmstrip, a film-exposure backframe opening, a pair of parallel film edge guides located apart from each other a distance substantially equal to the width of the filmstrip to guide the filmstrip over the backframe opening, and a pair of leader edge guides located parallel to the film edge guides and apart from each other a distance less than the width of the wider leader, but greater than the distance separating the film edge guides, in order to make the wider leader be bent widthwise at opposite longitudinal edge portions of the wider leader between the film edge guides and the leader edge guides, whereby the wider leader is prevented from having to significantly increase the size of the one-time-use camera.
    • 一次性照相机包括具有一定宽度的胶卷和用于胶片的胶片引导件,其另一宽度大于胶片的宽度,胶片曝光后框架开口,一对分开的平行胶片边缘导轨 彼此之间的距离基本上等于胶片的宽度,以将胶片引导到背框开口上;以及一对前导边缘引导件,其平行于胶片边缘引导件并且彼此分开,距离小于宽度的宽度 但是大于分离胶片边缘引导件的距离,以便使更宽的前导件在胶片边缘引导件和引导片边缘引导件之间的较宽的引导件的相对的纵向边缘部分处宽度方向弯曲,由此防止较宽的引导件 必须显着增加一次性照相机的尺寸。

    • A subassembly for a one-time-use camera includes a main body part that has a film take-up chamber adapted to receive a film spool and a film supply chamber for an unexposed film roll, a film winding thumbwheel supported for winding rotation in engagement with the film spool to similarly rotate the film spool to take up an exposed filmstrip, and an anti-backup pawl engageable with the thumbwheel to prevent unwinding rotation of the thumbwheel and disengageable from the thumbwheel to allow unwinding rotation of the thumbwheel to permit the film spool to be similarly rotated to unwind a fresh exposed filmstrip from the film spool to form the unexposed film roll. The film take-up chamber is configured to allow the film spool to be received in the film take-up chamber in a film unwinding position for unwinding rotation of the film spool and a different film winding position for winding rotation of the film spool. The anti-backup pawl has an actuator which when actuated disengages the anti-backup pawl from the thumbwheel and which is located in the film take-up chamber to allow the film spool when received in the film take-up chamber in the film unwinding position to actuate the actuator to disengage the anti-backup pawl from the thumbwheel, but not when the film spool is received in the film take-up chamber in the film unwinding position.

    • A cassette retaining apparatus comprises a holding chamber into which a film cassette is to be inserted and from which the cassette may be removed, and retaining means biased into engagement with the film cassette to retain the cassette in the chamber. The retaining means exerts one force to be biased into engagement with the film cassette, which force incidentally resists insertion of the cassette into the chamber though is relatively weak to make it easy to manually insert the cassette into the chamber, and exerts another force to be biased into engagement with the film cassette, which force incidentally resists removal of the cassette from the chamber and is relatively strong to make it difficult for the cassette to be unintentionally dislodged from the chamber.
    • 盒保持装置包括一个保持室,一个胶片暗盒将被插入该保持室中,该盒可被从该保持室中取出;以及保持装置偏置成与胶片暗盒接合以将盒保持在该腔室中。 保持装置施加一个力以被偏压成与胶片暗盒接合,这种力偶然地抵抗盒式磁带插入到盒中,尽管它相对较弱,使得容易将胶卷手动地插入到盒中,并施加另一种力 偏压成与胶片暗盒接合,这种力偶然地阻止了盒从盒中的移除,并且相对较强,使得盒难以无意地从室中移出。

    • A camera comprising a film winder manually rotatable in a film winding direction about an axis and having a continuous alternating series of teeth and spaces concentric about the axis, and an anti-backup device having a tooth that can be received in any one of the spaces to bottom out in the space in order to prevent reverse rotation of the film winder in a film unwinding direction, is characterized in that the film winder is constructed to be tilted from being perpendicular to the axis in order to only partially retract any one of the spaces that has received the tooth from the tooth, when one manually rotates the film winder in the film winding direction, whereby as long as the film winder is tilted the tooth cannot bottom out in any one of the spaces that has received the tooth. This results in a film winder and anti-backup device that are quietly operating.

    • A camera assembly has a support that defines an optical axis. The support has a forwardly extending cam finger. The cam finger has a first cam surface that is inclined relative to an imaginary line parallel to the optical axis. A guide has a forward rim that is spaced from the support. The support and guide are separate pieces that are joined together. The guide has a notch that receives the cam finger. The notch has a second cam surface that parallels and is spaced from the first cam surface. The cam surfaces together define a cam slot having first and second opposed ends. A lens barrel selectively translates along the optical axis between an inner position and an outer position relative to the support. The lens barrel has a cam follower that extends into the slot and is movable along the slot between the ends.
