The Minoltaflex Automat is an evolution of the earlier Minoltaflex, from which it retains the same body casting, viewfinder and front standard. Unlike the previous model, the camera has an advance crank on the photographer's right, winding the film and cocking the shutter in the same movement. It automatically stops for each exposure, and it is unlocked by tripping the release button. The frame number is displayed in a small round window on the same side.
The L-shaped back is identical to that of the Minoltaflex. It is hinged at the top and retained by a latch at the bottom; the serial number is inscribed inside and there is an exposure table attached behind — the latter is written in English, something rather surprising for a Japanese camera of the era. The two film flanges placed on the photographer's left are pulled out for film loading, and the position of the first exposure is set via a red window, placed under the camera and protected by a sliding cover. After that, the exposure counter mechanism is engaged by a small button at the top of the right-hand side plate.

The front plate is moved back and forth for focusing, and has a silver finish on all sides, replacing the black finish of the original Minoltaflex. Compared with the previous model, the camera also has newer strap attachments on both sides, and the focus knob has been moved to the photographer's left to leave space for the advance crank. The knob itself has an unchanged chrome finish with a black top, and runs along a black depth-of-field scale showing indications for 3.5, 8 and 16 apertures.

The viewfinder provides automatic parallax correction via a mask on the ground glass screen, which moves back and forth when the focus knob is turned, the same as on the previous Minoltaflex. The four-fold viewing hood, inspired by that of the Ikoflex II, is the same too. Its middle part has the shape of a truncated pyramid and a TIYOKO logo in the middle; it can be pushed back, releasing a built-in magnifying lens then revealing a sports finder. The words MINOLTA and AUTOMAT appear on the nameplate, placed in front of the viewfinder.
The Minoltaflex Automat has the same lenses as the regular Minoltaflex. The taking lens is a four-element Promar 75mm f/3.5, made by Asahi Kōgaku (predecessor of Pentax); the marking on the rim is Promar Anastigmat Nippon or Promar Nippon. The viewing lens is a 75mm f/3.2, marked Minolta Anastigmat Nippon or Minolta Nippon, reportedly made by the Chiyoda company itself, perhaps in the Sakai plant. Both lenses have a silver rim, thicker than on the Minoltaflex, and take 31.5mm diameter push-on accessories.

The shutter is a Crown II (B, 1–300) made by Chiyoda itself. The name CROWNⅡ–TIYOKO is inscribed on a small crescent-shaped nameplate screwed to the shutter plate, on the left of the lens (as seen from the front); the aperture scale is on the other side. The release lever mounted on the first examples was soon subsituted by a button is placed on the front plate, under the shutter unit (see the variations below). It is interlocked with the advance mechanism to provide double exposure prevention.

The dimensions are 98×100×138mm, and the weight is 1,000g.
Commercial life Edit
|Minoltaflex Automat in the October 1941 catalogue by Asanuma Shōkai. (Image rights)|
Many sources say that the Minoltaflex Automat was released in 1939; this date appears in the chronology published by the company in September 1958 in Shashin Kōgyō, in Minolta's fifty-year chronicle and is repeated elsewhere. However the camera does not appear in the official list of set prices compiled in October 1940 and published in January 1941, which gives a supposedly exhaustive list of all the Japanese camera production.
The earliest appearance of the camera known so far is in the October 1941 catalogue by Asanuma Shōkai, where the camera is listed for ¥493 — this price includes the lens cap but not the ever-ready case, sold separately for ¥14.16. The camera was advertised in Japanese photographic magazines from January 1942. It seems that the price remained unchanged at least until January 1943. At the time, the Minoltaflex Automat was the most expensive of all Japanese cameras, except the Canon.
The Minoltaflex Automat is mentioned in the April 1943 government inquiry on Japanese camera production, and the last reported advertisement is dated August 1943; the production was probably stopped around that time.
It seems that one of the TLR models made by the Chiyoda company was supplied to the military and received an official inventory name. Awano suggests that this was the Minoltaflex Automat, but an interview of Tashima Gizō mentions the "Flex", probably meaning the original Minoltaflex.

The early examples have the release lever on the side of the front plate, as on the original Minoltaflex, and have thick lens rims. Examples are known with body number in the 11xxx range and taking lens number in the 96xxx and 97xxx range. (The lowest body number observed so far on a Minoltaflex Automat is no.11406.)
|Serial number inside the back. (Image rights)|
The regular examples have a release button on the front plate, below the shutter housing, and have thinner lens rims. Surviving examples are known with body numbers from 14587 to 23846, taking lens numbers from 100151 to 112188 and viewing lens numbers from 17334 to 29465. The engraving on the lens rims lost the word Anastigmat around taking lens no.106000 and viewing lens no.23000. The late examples with body number above c.20000 have no exposure table on the back (as for the original Minoltaflex).
One camera with interesting features was shown by Mieno Tsuguharu in a letter to Camera Collectors' News. It has taking lens no.112188 and viewing lens no.29465, the last observed on an Automat. These were mounted on a slightly earlier body, with serial no.18828 and an exposure table on the back. Removal of the MINOLTA AUTOMAT nameplate reveals the abbreviated company name Chiyokō in kanji characters 千代光, and No26199. Similar engravings (with No2602) are found on the "type A" interchangeable-lens prototype, which was probably made c.1943 for the military. The Automat pictured in the letter also has a PC synch socket at the front, at the exact same place as the synch connector of the "type A" camera. Though no textual evidence has remained of this, it looks like this particular Automat was part of a very late batch with added flash synchronization, perhaps made on behalf of the military. The extra serial number 26199 might be a military number in a sequence starting at 2600 or 2601, perhaps an allusion to year 2600 in the old Japanese calendar used during the military period, corresponding to 1940 CE.
Total production and current condition Edit
It is difficult to give a precise estimate of the total production, because the numbering sequence was common to the Minoltaflex. From the known serial numbers, it seems certain that less than 25,000 were made of the two models; for the Minoltaflex Automat alone, we can attempt a rough estimate of 5,000 to 10,000 units.
It is said that the film advance mechanism of the Minoltaflex Automat was not very reliable, because the materials used during the troubled production period were inadequate. Various surviving cameras indeed show traces of repair and tinkering with the advance mechanism. For example, at least one very late camera was modified by removing the auto-stop mechanism and exposure counter, and moving the red window to the middle of the back, for manual control of the film advance.
|Ever-ready case. Picture by eBayer hbpartner. (Image rights)|
The original ever-ready case is made of brown leather, and has the name MINOLTA AUTOMAT embossed at the front, above the latch. The double lens cap is black with the TIYOKO logo at the top and the name Minolta Flex at the bottom.
|Left: close-up lens set P.X–No.1. Right: yellow filter. Pictures by eBayer hbpartner. (Image rights)|
The filter pictured above was certainly offered by Asanuma Shōkai as a dedicated accessory; it has a silver rim, engraved Minolta–automat Filter, and comes in a small case embossed Minoltaflex.
The close-up lens set is exactly similar to the set sold for the original Minoltaflex, but for the larger 31.5mm diameter. It was copied on the Proxar and Rolleipar set of the Rolleiflex, and consists of two identical lenses, inscribed 31.5 and P.X–No.1 or P.X–No.2, and one parallax correction device for the viewing lens, inscribed Minolta Flex Auto Mat and Ro–P.X–No.1 or Ro–P.X–No.2. The three elements are contained in a small case with a Minoltaflex embossing.
|Left and middle: square hood. Right: round hood with filter holder. Pictures by eBayer hbpartner. (Image rights)|
At least two types of hoods are known. The metal square hood has a lever on the side, certainly to release the springs holding it firmly to the camera; it is engraved Minolta–automat at the top and comes in a small brown case. The round hood has a built-in filter holder and spring-loaded clips to fit on the camera's taking lens. It comes in a small cardboard box which has the Minolta logo, markings identifying it as a "lens hood for the Minolta Automat" (ミノルタオートマット専用レンズフード), and the name of Asanuma Shōkai.

Furthermore, this discussion occurred years before the "type A" prototype was rediscovered in a 1998 article of the same magazine; otherwise, Awano would surely have seen the connection.
