PURPOSE:To attain switching between autofocusing (AF) and manual focusing (MF) by executing simple displacement operation from a camera body (CB). CONSTITUTION:A collar 117 is fixed on a lever 116 pivotally supported around a supporting point 118 and the collar 117 engaged with a pin 21 is coupled with a oblong hole of a flange. The pin 21 is always pushed out in a CB direction by a receiving pin 119 excited in the CB direction by a spring 120. An AF-MF switching clutch shaft 9 is supported by a lever 110 as shown in Fig.B, the lever 110 is fixed pivotally around a shaft 121 and a pinion 91 is excited in a direction to be engaged with the inner gears of an MF disk 61 and an AF disk 72. Thereby, the lens is always set up to the MF mode. When the lens is loaded to a camera and the pin 21 is moved in a direction shown in Fig.B, the pinion 91 is pushed out and the AF mode is formed. Thereby, AF and MF can be easily switched by the simple displacement operation of the pin 21. |
