    • A lens position detecting device comprises at least two columns of contacts each having a plurality of contacts, the columns being disposed side by side, and a brush having a plurality of brush segments each for contacting the contacts of the corresponding one of the columns and detecting a voltage at a contact thereof. Each contact of one column is shifted by a predetermined amount from the contacts of an adjacent column. The voltage at one contact is different from that at another contact of the same column, and these different voltages detectable at the contacts of one column constitute the same group as for the other columns. The lens position is determined depending on the combination of at least two voltages detected through the brush segments. The lens positions are thus divisible into a greater number of increments at the same time that the device is composed of a smaller number of elements.
    • 透镜位置检测装置包括至少两列触点,每个触点各自具有多个触点,所述列并排设置;以及刷子,其具有多个刷部分,每个刷部分用于接触相应一个列的触点并检测 其接触处的电压。 一列的每个接触从相邻列的触点偏移预定量。 一个触点的电压与同一列的另一个触点的电压不同,在一个反应​​器的触点处可检测到的这些不同的电压构成与其他色谱柱相同的组。 透镜位置取决于通过刷段检测到的至少两个电压的组合。 因此,透镜位置可以与更多数量的增量相分离,同时该装置由较少数量的元件构成。

    • Continuous photography control for a camera wherein an autofocus system is provided, and a motor is used commonly to move a taking lens for focusing and to open and close a shutter for exposure. When a mode switch is operated to set a continuous photography mode wherein plural exposures are continuously performed, the motor is driven to move the taking lens from an initial position into an in-focus position that is determined by the autofocus system and, thereafter, to open and close the shutter a selected number of times while maintaining the taking lens in the in-focus position. The taking lens is returned to the initial position after the selected number of exposures are performed. Alternatively, when another mode switch is operated to set a photography mode wherein only a single exposure is performed per one depression of the shutter button, then the taking lens is moved from the initial position to the in-focus position; the shutter is opened and closed only once; and then the taking lens is moved back to the initial position.

    • A camera with a magnetic recording device that may record optional data on a magnetic recording layer of a photo filmstrip while the photo filmstrip is advanced by one frame after each exposure. The optional data is print number data designating the number of copies to print from a picture frame and/or caption data designating a content and a language of a caption to print with a picture frame. The optional data is selectable by photographers for each picture frame by operating a multi-operation button when the camera is put in a mode set-up standby stage upon a shift switch being turned on by pushing a shift button. The multi-operation button is virtually divided into four sections. The camera is put in a print number setting mode when one of the sections that is provided with a mark indicating the print number setting mode, is pressed in the mode set-up standby stage. The camera is put in a caption setting mode when another section that is provided with a mark indicating the caption setting mode, is pressed in the mode set-up stage. The print number data or the caption data as selected in the print number setting mode or the caption setting mode is stored in a RAM, and read out from the RAM when the magnetic recording device records it on the magnetic recording layer.
    • 具有磁记录装置的相机,其可以在每次曝光之后将照相胶卷在照相​​胶片前进一帧时将可选数据记录在照相胶片的磁记录层上。 可选数据是指定从图片帧打印的份数的打印数量数据和/或指定要用图片帧打印的内容和字幕的语言的字幕数据。 当通过按下换档按钮开启换档开关时,当相机处于模式设置待机阶段时,通过操作多操作按钮,可以通过摄影者为每个画面选择可选数据。 多操作按钮实际上分为四个部分。 在模式设定待机阶段按下设置有指示打印编号设定模式的标记的部分之一时,将相机置于打印编号设定模式。 当在模式设定阶段按下设有指示字幕设定模式的标记的另一部分时,将照相机置于字幕设定模式。 在打印数设定模式或字幕设定模式中选择的打印数量或字幕数据被存储在RAM中,并且当磁记录装置将其记录在磁记录层上时从RAM中读出。

    • A central processing unit (CPU) is reset during the removal of a battery or the voltage drop, while, in an electrically erasable/programmable read-only memory (EEPROM), there is stored and held information of the camera operation immediately before the reset and the number of film frames. Then, when the CPU becomes operable by the exchange of batteries and the like, the information of camera operation immediately before the reset and the number of film frames are read out from the EEPROM during the processing at the initial stage thereafter, the operations corresponding to the information of camera operation is continued and the number of film frames thus read out is changed by one and set as the film count value when the information of camera operation indicates one frame delivery. With this arrangement, the interrupted frame delivery is also counted as one frame, so that the final frame is prevented from entering a photographing preventing region of a film.

    • A camera includes a taking lens system changeable in focal length between at least a short focal length suitable for wide-angle photography and a long focal length suitable for telephotography. The lens system is held in a lens barrel which is axially displaced by means of a motor to change the lens system between at least the two different focal lengths. The camera is provided with a controller for sequentially controlling the motor to move the lens barrel in one axial direction so as to change the lens system to have one of the different focal lengths selected by a focal length selecting switch, to move the lens barrel in the opposite axial direction when the lens barrel does not reach a position wherein the taking lens system has the selected focal length in a predetermined time period, and to stop when the lens barrel reaches the position wherein the taking lens system has another one of the different focal lengths. For detecting the lens barrel at the axial position where the taking lens system has the different focal lengths, the camera is provided with a detector for detecting an unusual motion of the lens barrel in cooperation with the controller.
