摘要： The present invention relates to the exposure compensation information forming apparatus for a camera, particularly for forming the aperture and the totally opened aperture value information. Until now in order to compensate the totally opened aperture value contained in the output of the light measuring circuit and the aperture value the information setting means for the totally opened aperture value and that for the aperture value are provided, whereby both setting means are mechanically engaged with each other so as to form the totally opened aperture and the aperture information. Thus, the engaging mechanism of both of the above means is complicated, which is inconvenient. The present invention provides an exposure compensation information forming apparatus by means of which the aperture information can be composed from the totally opened aperture with a very simple circuit composition so as to overcome the above disadvantage.

摘要： A camera exposure mode setting device including a dial which can be moved to select a number of different exposure modes, one of which is controlled by a self-timer circuit in the camera. The device also includes circuitry coupled to the dial which operates to prevent the self-timer circuit from operating unless the dial is maintained in a self-timer exposure mode position. In a preferred embodiment, a push button extends from the dial, the button being arranged to prevent the dial from being moved to select the self-timer mode unless the button is first pushed down by the user.

摘要： In the disclosed system, a camera of the type which manually presets a diaphragm aperture and particularly for a camera which operates with a computer flash device. For flash operation, the aperture of such a camera must be set at a value suitable for the flash device. A signal representative of an aperture value suitable for the computer flash device and a signal representative of a preset aperture value are compared and, when these two values coincide with each other, the coincidence is displayed by a display device arranged within the view finder to let the photographer know that the camera has been set at an aperture value required for flash photography.

摘要： A device for preventing erroneous operation of a camera is disclosed. The device includes an electromagnet for closing the camera shutter. Current supply apparatus supplies current to the electromagnet. A detection device is employed for detecting whether current from the current supply device has been supplied to the electromagnet. The detection device produces a detection signal when the current is supplied to the electromagnet. A signal generation device has a switch which closes in response to the release operation wherein the signal generation device generates an electrical signal when it receives the detection signal from the detection device. A control device is included for generating a check signal and a release signal. The control device produces the check signal for a predetermined period of time only when it receives the electrical signal from the signal generation device to actuate the detection device. The control device generates the release signal when it receives the detection signal from the detection device. Finally, an electromagnet is included for opening the shutter which is actuated by the release signal from the control device so as to operate only when the current passage to the shutter control electromagnet is detected.

摘要： An apparatus for setting an exposure control factor into a camera in the form of a digital signal without using a code plate or a plurality of switches. A pulse train is fed to a binary counter through an AND circuit which, upon selective receipt of gating-on and gating-off signals, operates to initiate and terminate flow of pulses therethrough respectively. When the counter has counted the selected number of pulses, the photographer who is viewing a digital display unit cooperative with the counter to detect this pulse number may actuate a button to produce the gating-off signal, thereby a corresponding desired value of the exposure control factor is set into the camera as a function of the number of pulses counted.

摘要： The present invention relates to a camera with a displacement means for controlling the exposure amount as the function of the mechanical displacement position. The displacement means are so designed that a brush is slid over a comb-shaped conductive pattern mechanically linked with the displacement means so as to convert the displacement position of the displacement means into a pulse number. Further, when the pulse number reaches a certain determined value, the displacement means is stopped in such a manner that the pulse number corresponds with the exposure amount and characterized in that, by determining the position at which each conductor of the comb-shaped conductive pattern is provided, relative to the position at which the displacement means stops in accordance with the displacement speed of the displacement means, the displacement amount of the displacement means due to the time delay since the pulse number reaches a certain determined amount till the displacement means actually stops is compensated so that the pulse number always corresponds with the displacement position in a precise way.

摘要： Embodiments of the invention reduce a possibility that a head will collide with a medium when the clearance between the head and the medium is adjusted by using a medium, and sufficiently reduce the clearance even at an initial stage of accessing a data area. In one embodiment, a hard disk drive (HDD) keeps a heater in an OFF state for a period of time from the start of seek operation until the specified timing after a following mode starts. This prevents a head element from colliding with a magnetic disk, and also prevents flying properties from changing due to the deformation of the ABS. In the above specified timing, the heater is switched from OFF to ON. Specifically, for example, on completion of seek operation, in the timing in which a head arrives at a target track, or in the timing in which an HDC/MPU enters the following mode, the heater is turned ON.
摘要翻译： 本发明的实施例减少了当通过使用介质来调整头部和介质之间的间隙时头部将与介质碰撞的可能性，并且即使在访问数据区域的初始阶段也足够地减小间隙。 在一个实施例中，硬盘驱动器（HDD）将加热器保持在关闭状态，持续一段时间，从搜索操作开始直到在后续模式开始之后的指定定时。 这样可防止头元件与磁盘碰撞，并且还防止由于ABS的变形引起的飞行性能的变化。 在上述指定的时间，加热器从OFF切换到ON。 具体地，例如，在寻道操作完成时，在头到达目标轨道的时刻，或者在HDC / MPU进入后续模式的定时中，加热器被接通。
