    • A photographic printing apparatus includes a lens unit and a lens mount which are joined to each other in a separable manner. The lens mount includes therein a drive motor and a drive force transmitting mechanism to adjust the focal distance and aperture of the lens unit. A plurality of lens units having different focal distances are provided, from which a lens unit suitable for a printing magnification is automatically selected for printing. Each lens unit is provided with external connection members which are connected to an aperture adjusting mechanism and the focal distance adjusting mechanism of the lens unit. The lens mount to which the lens unit is attached is provided with members which are engaged with the external connection members of the lens unit to displace them. The displacement of these members is effected by motors provided on the lens mount. With this structure, the cost of lens units can be reduced, and the efficiency of the printing operation can be increased.

    • An apparatus for selectively supplies one of a plurality of photosensitive materials having different widths to an exposure unit. The width of the potosensitive material and the exposure unit.The width of the photosensitive material and a width of the image frame are detected. By comparing the detected widths with each other, a control circuit will select the magazine accommodating the photosensitive material having a width corresponding to that of the image frame. If the selected magazine is already supplying the photosensitive material, it continues to feed it. If not, the control circuit will command to cut off the exposed portion of the photosensitive material, rewind its nonexposed portion by the transfer means, and deliver only the printed photosensitive material remained in the exposure unit. Then, the control circuit selects the photosensitive material whose width corresponds to that of the image frame. Thus, the photosensitive material is changed over automatically according to the width of the image frame of the negative film.
    • 一种用于选择性地向曝光单元提供具有不同宽度的多个感光材料中的一种的设备。 感光材料和曝光单元的宽度。 检测感光材料的宽度和图像帧的宽度。 通过将检测到的宽度相互比较,控制电路将选择容纳具有对应于图像帧的宽度的感光材料的盒。 如果所选择的杂志已经提供感光材料,它将继续进纸。 如果不是,则控制电路将命令切断感光材料的暴露部分,通过转印装置倒回其未涂覆的部分,并仅传送留在曝光单元中的印刷的感光材料。 然后,控制电路选择其宽度对应于图像帧的感光材料。 因此,感光材料根据负片的图像帧的宽度自动地改变。

    • A method and device for rotating images about an optical axis by changing the direction of a light path by a composite mirror unit having a simple structure. A printing device has a light source for emitting light to an image Xa on a negative film, a printing lens for adjusting the magnification of the light that passes through the image, and a composite mirror unit for reversing the light path to print an image Ya on a printing material. The entire composite mirror unit can be rotated through a predetermined angle about a rotary shaft by a driving motor. The composite mirror unit has two oppositely arranged mirrors which are mounted on separate blocks and so as to be inclined by 45.degree. with respect to the vertical. By turning the unit by .+-.45.degree. from the reference position (0.degree.), the image will rotate by 90.degree. or 270.degree. with respect to the image Xa.

    • An in-cylinder pressure detecting device of a direct injection type internal combustion engine is provided in which a ring-shaped pressure detection element (34) surrounding a fuel injection hole (33b) is provided in the vicinity of an extremity of an injector (20) that injects fuel into a combustion chamber. Since the pressure detection element is provided on the injector, not only is it unnecessary to change the shape or structure of the cylinder head or the combustion chamber in order to provide the pressure detection element, but it is also possible to cool the pressure detection element (34) by fuel passing through the inside of the injector to thus enhance the precision of pressure detection and the durability. Further, since the ring-shaped pressure detection element (34) surrounds the periphery of the fuel injection hole (33b), it is possible to maximize the dimensions of the pressure detection element (34) to thus further enhance the precision of pressure detection while avoiding interference between the pressure detection element (34) and fuel injected via the fuel injection hole (33b).
    • 提供一种直喷式内燃机的缸内压力检测装置,其中,在喷射器(20)的末端附近设置围绕燃料喷射孔(33b)的环状压力检测元件(34) )将燃料喷射到燃烧室中。 由于压力检测元件设置在喷射器上,为了提供压力检测元件,不仅不需要改变气缸盖或燃烧室的形状或结构,而且还可以将压力检测元件 (34)通过喷射器内部的燃料,从而提高压力检测的精度和耐久性。 此外,由于环状压力检测元件34围绕燃料喷射孔33b的周围,所以能够使压力检测元件34的尺寸最大化,能够进一步提高压力检测的精度, 避免压力检测元件(34)与经由燃料喷射孔(33b)喷射的燃料之间的干扰。
