a foreigners' guide to eremeka arcades - 外国人のためのエレメカアーケードゲームガイド: 1976 Fly Flap - フライ・フラップ by こまや (Komaya) & 吉山商事製造 (Yoshiyama Shoji Manufacturing)

Name: Fly Flap - フライ・フラップ
Year: 1976
Company: こまや (Komaya) & 吉山商事製造 (Yoshiyama Shoji Manufacturing)

Fly Flap is a game where the "flies" on the playfield light up and move around. There is a buzzing sound, until a fly "lands" and stops on one spot. The player must then use a fly swatter (not pictured) to swat the fly to kill it.

It is hard to read, but I believe the company that made it for Komaya is 吉山商事製造 (Yoshiyama Shoji Manufacturing) [thank you to user michelentongs]

フライフラップ
ユーモラスなゲーム機モグラ退治が人気を呼んでいる折、吉山商事製造、こまや製作所販売による共同開発で、ハエツダキゲーム機「フライフラップ」が登場した。
同機はICを使わないオールメカ製。版面上の16匹のハエを結ぶゴースをライトが点灯し、16匹のハエのどれかに止まる。その瞬間、お客の待ったハエタタキがビシャリと来る。ハエが飛びたつ前にうまく命中すれば、金属性のハエの日承とハエタタキの金網とが接触し、ドーン”という命中芹がでる。ハエが回停止するうち、18回命中すればリプレイできる。
㈱マル三商会の神戸・三の宮センターブラザのロケーションテストでは、ワンプレ30円で、日曜日約四千円、平日で二~三千円と上々の成績とか。
開発に当り、上下左右ランダムにハエ点灯させず、点線状に移動させたのは、ブレーヤーがハエタタキを振り回す危険をきけたのと、プーンというハエが飛ぶ効果音を生かすためとのこと。命中所の“ドン”も不快感を与えない様にとの配慮。
ハエの点灯停止タイムは3段階に調節できるので、ロケーションによってリプレミの鬱かしさを変え。再挑戦を誘発することもできる。料金30円も、セレクターで変更可。この夏に向け、100台の販売計画が立てられているが、ハエの少なくなった昨今、ハエタタキが郷愁を呼び、人気が期待される。

Fly flap
At a time when the humorous mole extermination game machine was gaining popularity, the fly flap game machine ``Fly Flap'' was jointly developed by Yoshiyama Shoji Manufacturing and Komaya Seisakusho Sales.
This machine is an all-mechanical machine that does not use IC. A light lights up the gorse that connects the 16 flies on the board, and it lands on any of the 16 flies. At that moment, the flycatcher that the customer had been waiting for suddenly arrives. If you successfully hit the fly before it flies away, the metal fly's wire mesh will come into contact with the fly swatter's wire mesh, causing a hit. If you hit 18 times while the fly stops, you can replay the fly.
In the location test conducted by Marusan Shokai Co., Ltd. at Sannomiya Center Plaza in Kobe, one ticket costs 30 yen, and on Sundays it costs about 4,000 yen, and on weekdays it costs 2,000 to 3,000 yen, which is excellent.
During development, the reason why the flies were not lit up, down, left, right, and above at random, but moved in a dotted line, was to avoid the risk of Breyer swinging the fly swatter around, and to make use of the sound effect of the flies flying. Care was taken to ensure that the "don" at the hit point did not cause any discomfort.
The fly lighting stop time can be adjusted in 3 stages, so you can change the depressingness of the replay depending on the location. It can also encourage you to try again. The price of 30 yen can also be changed with the selector. Plans are being made to sell 100 units for this summer, and with the fly swatting having become scarce these days, the fly swatter evokes nostalgia and is expected to be popular.

Yoshiyama Shoji has a listing within the 1976 machine directory, saying they are a manufacturer of machines. While the scan of Coin Journal is poor, we will assume that Yoshiyama Shoji built these machines. Hopefully we can find a better copy of 1976-06 Coin Journal and verify that we have this correct.
