Abstract
Abstract A turret wherein, in order that the assembly may be easy and a turret board may be stopped accurately in a predetermined position, the turret board provided with a plurality of notches is connected with a driving plate so as to be relatively rotatable in a slight range and the driving plate is so made as to be stopped by the cooperation of incisions provided in response to the respective notches in the turret board with a detecting element or the cooperation of a locking member with the detecting element just after the locking member engages with one of the notches. The detecting element is such photoelectric element as a photointerrupter.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
159 words
A turret comprising a rotatable turret board holding thereon a plurality of lenses of different magnifications and having a plurality of notches serving as position indexes on the peripheral edge thereof each adjacent to a said respective lenses, a locking member formed as a two-arm lever one arm of which is engageable with any one of said plurality of notches to lock said turret board, a driving plate operatively connected to said turret board so as to be relatively rotatable by a predetermined range to rotate said turret board, a driving motor connected to said driving plate to rotate said driving plate, and a detecting element set near said turret board and cooperating with the other arm of said two-arm lever to issue a signal for stopping said driving motor when the one arm of said two-arm lever engages with one of said plurality of notches to lock said turret board and said other arm including a tip part.
Claim 2
Dependent Claim
159 words
A turret comprising a rotatable turret board holding thereon a plurality of lenses of different magnifications and having a plurality of notches serving as position indexes on the peripheral edge thereof each adjacent to a said respective lenses, a locking member formed as a two-arm lever one arm of which is engageable with any one of said plurality of notches to lock said turret board, a driving plate operatively connected to said turret board so as to be relatively rotatable by a predetermined range to rotate said turret board, a driving motor connected to said driving plate to rotate said driving plate, and a detecting element set near said turret board and cooperating with the other arm of said two-arm lever to issue a signal for stopping said driving motor when the one arm of said two-arm lever engages with one of said plurality of notches to lock said turret board and said other arm including a tip part.
Claim 3
Dependent Claim
40 words
A turret according to claim 1, wherein said detecting element is a photoelectric element of the reflection-type photointerrupter type arranged so as to be able to be opposed to the tip part of the other arm of said locking member.
Claim 4
Dependent Claim
40 words
A turret according to claim 1, wherein said detecting element is a photoelectric element of the transmission-type photointerrupter type arranged so as to be able to be opposed to the tip part of the other arm of said locking member.
