  • Patent number: 5010420
    Abstract: An image processing apparatus furnished with an overhead projector has an image projecting function and an image-forming function. The image processing apparatus is designed to detect the movement of an original support table or a reflection-type focusing plate during projecting of an original. The result is that the original support table is free from being heated by the focusing plate and also that the focusing plate is free from any deviation of its axis of light, thus preventing the reflected light from striking on the eyes of the operator.

  • Patent number: 4956664
    Abstract: An image processing apparatus comprising: an input unit for inputting an image of an initial original; a support table on which the initial original is to be set, the support table being movably mounted along the input unit; a reflection-type focusing plate on which an OHP (overhead projector). original is to be set, the focusing plate being disposed along side the input unit; an image forming unit disposed under the focusing plate for forming on a sheet an image inputted from the input unit to provide an OHP original; and a projecting unit disposed above the focusing plate for projecting an image of the OHP original set on focusing plate.

  • Patent number: 4742369
    Abstract: In an electronic still camera, a solid-state imaging element and a photosensitive film which receive an object image and arranged on the optical path of an optical lens system. The object image is simultaneously formed on the solid-state imaging element and the photosensitive film upon depression of a shutter switch.

  • Patent number: 4657405
    Abstract: In a stop watch, when a switch is depressed, hands are operated to start timing. Every time a split time switch is depressed, the time intervals between time points at which the split time switch is depressed are sequentially stored in a memory. Therefore, when the switch is re-depressed, the stop watch terminates its time measurement. A plurality of split times up to the end of time measurement can be reproduced, from the latest split time to the earliest split time.

  • Patent number: 4652140
    Abstract: In an analog type timepiece, no electronic display is provided, and a plurality of alarm times are presettable. These preset alarm times can be easily recognized by using a simple hand. A reference signal oscillator, wave shapers, stepping motors, counters, coincidence detector and a buzzer are provided in the timepiece, thereby sequentially quick-shifting the hand mechanism to the predetermined alarm time positions.
