For the Auto-Reflex, the meter sensor is mounted on the front, right-hand side of the camera. This is not TTL metering, although it does offer a shutter-preferred, auto-exposure mode. TTL auto exposure appeared in a Konica a few years later, with the Autoreflex T (FTA in Japan). It has the new Konica Bayonet II mount, which is also often called K/AR mount. PX675 type mercury batteries are only needed for the light meter. Shutter speeds run from 1s to 1/1000s and B.
