Title: Range measuring unit
Inventor: SUEYOSHI OSAMU
IPC: G01C3/00
Filed: 1988-05-10
Abstract: PURPOSE:To measure range with high accuracy by counting the number of pluses at the time of moving a lens system from a reference position to a focusing position and converting the number of pulses into the range. CONSTITUTION:At least one lens of the lens system 1 is moved from the reference point equal to infinity or closest distance to the focusing position by using a lens moving means 4. A focusing detection means 2 detects that focusing is accomplished owing to the above-mentioned movement. A pulse counting conversion circuit 5 counts the number of pulses necessary for moving from the above-mentioned reference point to the focusing position and converts the number of the pulses into the range, then outputs it to a recording means 8 through a switch 7. Thus, the range to an object can be measured with high accuracy and can be recorded in the recording means.
