发明名称 CAMERA
摘要 PURPOSE:To obtain a small-sized and light weight camera by moving a photographing lens and a finder lens by means of a link mechanism. CONSTITUTION:When an operational pin 13a is moved in a direction D, energizing power is applied counterclockwise to a switching lever 13. Thereby a front group lens switching plate 3 moves downward to abut on an eccentric pin 24. Due to the move of said plate 3, counterclockwise turning power is added to a lever 19, then a rear group lens switching lever 9 moves upward to abut a leading part 9b on an eccentric pin 26. Namely, a front group lens barrel moves in a direction A, while a rear group lens barrel 2 moves in a direction B. As a result the titled camera attains the structure of a long focus distance lens. If the operational pin 13a is moved opposite to the direction D, the camera is switched to a short focus side. By moving the operation pin 13a, counterclockwise turning power is applied to the finder switching lever 32; therefore, the photographing lens and a finder optical system are converted interlockingly. Thus simple constitution is attainable.
