    • A lens driving apparatus is provided with an encoder for detecting the position of a taking lens system. The encoder has a contact array including a main contact corresponding to a predetermined focal length position of a taking lens system and a sub-contact which is spaced slightly from the main contact. When a focal length changeover switch is operated to set the taking lens system in the desired focal length position, a motor is driven at a high speed until the sub-contact is detected and thereafter is driven at a low speed until the main contact is detected. So as to stop the taking lens system at the focal length position always after moving in one direction, when the taking lens system is to move in the other direction for changing over from a first to a second focal length position, the motor is driven at a high speed to move the taking lens system in the other direction until the encoder switches off the sub-contact corresponding to the second focal length position after detecting that sub-contact, and then the motor is driven at a low speed to move the taking lens system in the one direction until the associated main contact is detected. The taking lens system may be stopped when an end of a main contact is detected, and is moved into the predetermined focal length position that corresponds to the opposite end of the main contact when the shutter release button is operated.
    • 透镜驱动装置设置有用于检测拍摄镜头系统的位置的编码器。 编码器具有接触阵列,其包括对应于拍摄镜头系统的预定焦距位置的主触点和与主触点间隔开的副触点。 当操作焦距切换开关以将拍摄镜头系统设置在期望的焦距位置时,电动机被高速驱动,直到检测到副接触,此后被以低速驱动,直到检测到主接触 。 为了在沿一个方向移动之后始终将焦点位置处的拍摄镜头系统停止,当拍摄镜头系统要沿另一方向移动以从第一焦距位置转换到第二焦距位置时,电机被驱动 高速地使拍摄镜头系统沿另一方向移动,直到编码器在检测到该次接触之后关闭与第二焦距位置相对应的副接触,然后以低速驱动马达以移动拍摄 透镜系统,直到检测到相关联的主触点。 当检测到主触点的一端时,拍摄镜头系统可以停止,并且当快门释放按钮被操作时,拍摄镜头系统被移动到对应于主触点的相对端的预定焦距位置。

    • A method for matching and splicing webs that splices, by use of splicing tape, a rear end of a strip-shaped flexible backing that is drawn and conveyed from an old roll and a front end of a strip-shaped flexible backing that is drawn and conveyed from a new roll, in a state in which the front end and the rear end are matched, wherein the method performs matching and splicing by executing: a preparation step of performing matching and splicing preparations by retaining a front end of a strip-shaped flexible backing of the new roll with one of a pair of cutting drums, and supplying splicing tape to a pair of splicing drums, respectively; a cutting step of cutting with the pair of cutting drums a strip-shaped flexible backing of the old roll and a strip-shaped flexible backing of the new roll in an overlapping state after the preparation step; a feeding step of feeding to a splicing position a rear end of the strip-shaped flexible backing of the old roll and a front end of the strip-shaped flexible backing of the new roll that are cut in the cutting step, as they are in a matched state; and a splicing step of using the pair of splicing drums to adhere and attach splicing tape to each of a front surface side and a rear surface side of a matching portion that is fed to a splicing position in the feeding step; wherein, in the preparation step, at least one of the pair of splicing drums is driven independently, and in the cutting step, the feeding step and the splicing step, the one of the pair of splicing drums is driven in synchrony with other drums.
