「USB仕様のボール式マウス」を
PC-98用のバスマウスに改造してみた品です

元のマウスはUSB仕様の「SANWA Scroll Mouse MA-441U」で
(PC周辺機器の「まとめ売り」の中に入っていた品なので 前所有者や使用履歴は不明です)
スクロール操作部が「回転式のホイール」ではなく
上下に傾ける「レバー式」のマウスで
中身の基板は 「MITSUMI」製でした
基板上のUSBコントローラ(IC)と関連部品を除去して
X/Y用出力部品(トランジスタと抵抗)を組み込みました(画像2枚目)

元のマウスの「スクロールレバー」は「ホイール」的に機能するものでしたが
バスマウスにはピン割り当てがありませんので
除去して穴を埋めてしまおうかとも考えましたが
ロータリーエンコーダーではなく「前後にスイッチが配置されている」構成でしたので
「前側SW:右ボタン」,「後側SW:左ボタン」に並列に配線接続してあります
つまり、「レバーを前に傾けると、右クリック」
「レバーを後に傾けると、左クリック」の操作になります(画像8枚目)
試しに操作した印象では「意外と使い易い」ものでした
(まぁ、「人による」,「慣れ」の部類と思いますので、ご容赦を。)
勿論、レバーを操作しないで通常の左右ボタンでのクリックは可能です

外観に損傷は無いですが 小傷や使用に伴う摩耗や痕跡はあります
汚れ具合と見た目の印象では、それなりに使い込まれているようです
元色はアイボリー寄りのライトグレーのようですが 底面を除いて黄変(経年変色)しています
上面の文字「Scroll Mouse SANWA SUPPLY」にカスレた部分があって
見た目が悪かったので サンドペーパーを軽くかけて落としましたが
下地の樹脂色が露出して 薄い白文字として見える状態になっています(画像7枚目)
あと、ケーブル先のミニDINコネクタのモールドの角をカットしてあります(画像3枚目)
(PCのコネクタに差し込み時にぶつかるため)

入手後に中性洗剤を使用しての水洗い洗浄で極端な汚れは落としましたが
製品としても古いものですし、使用経緯不明の中古品ですので
現状渡しとさせていただきます

動作確認は「98 note PC-9821La10」に接続して行いました
「移動」と「ボタン・クリック」、マウスとして操作出来ました
アプリケーションのメニュー項目や[OK]ボタンのクリックなどの
通常速度での操作に問題はないと思いますが
高速移動させた時には、停滞や一瞬の戻りなど不安定な挙動(REカウントミス)があるかもしれません!
DIY改造品ですので
全てのPC-9800シリーズで 確実な安定動作は保証できません!
使用環境の温度や経年による変化等で光学部に起因する動作不良となった場合は
「照射LED」と「受光フォト・トランジスタ」の機構的な「光軸合わせ(傾きの加減調整)」が必要になるかもしれませんし
電気回路(構成は単純)側で「照射LEDのドライブ電流」を増やしたり
スイッチングトランジスタ周りの抵抗値を増減させたりの対処が生じたりと
改造に興味をお持ちの方や電子工作が趣味の方でないと修復は難しいと思います
このような品ですので、確実に動作するマウスをお探しの方にはお勧めできません!


製品高さが3cm以上あるため
定型の「専用箱」を使用した発送を予定しています。

International Shipping Methods
Proxy bidding and purchasing services are becoming increasingly convenient. However, overseas shopping carries certain risks and issues. To reduce these risks and enhance shopping safety, please be sure to read the following information:

1. International Shipping

   Air Freight: If the item status is not confirmed within two days after the arrival notice, any customer complaints cannot be addressed with the seller.

2. After Receiving the Product

Please confirm and inspect the product as soon as possible to ensure that the product specifications, quantity, accessories, and description are correct

If, unfortunately, there are any issues, you can refer to the following examples on how to report related product problems:
1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

Important Notes: 1. If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, the international shipping cost for returns or exchanges will need to be borne by the member. You may refer to the EMS e-Express fee inquiry from the post office. If it involves alcoholic beverages or items that affect flight safety, the post office cannot be used for shipment, and only DHL can be used to ship back to Japan.
2. During the product complaint handling period, please retain the complete outer packaging of the product (including the shipping label information), and refrain from attempting any repairs or altering the original condition. Any modifications may result in the inability to process the case.

3. After Inspecting the Product

After receiving and inspecting the item, if you have any questions, it is recommended to contact Letao within 2 hours. Here are some reminders:

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.

2. You can call customer service, and the customer service will leave a message for you as below. Please provide the following information:
"Hello, we will first help you establish a complaint case for Product ID: _______ .But we need you to 2-3 clear photos of the product issue, including photos of the product problem, product packaging, shipping details slip, and outer box. Send them to service@letao.my and inform us of your desired resolution (failing to provide this may result in an inability to process subsequent matters). After sending the email, notify us in the customer service message. We will confirm with the seller as soon as possible. and if there are any related questions, we will contact you through the customer service message. Thank you for your cooperation."

Please provide:
1. "Product ID"
2. Photo of the "Delivery Note" (if any)
3. Photos of the outer box (including inner and outer packaging)
4. Photos of the product (Please include relevant descriptions to help us confirm with the seller)

Important Notes:
1. Do not include foreign text or other products in the background of the image.
2. Please keep the complete product packaging (including the shipping label information), and refrain from repairing or altering the original condition on your own, as any changes may result in the case being unable to be processed.
3. Please provide the relevant information within 48 hours to avoid missing the golden hour for reflection and causing situations that cannot be handled.
4. Due to 99% of Japanese sellers being unwilling or unaware of shipping goods overseas, if a seller is willing to handle the issue, the goods must be sent back to Japan, and the international shipping costs incurred must be borne by the member. Letao will use postal EMS international express to send the goods back to Japan.
5. As the goods are purchased from overseas, it may take approximately one to two weeks to complete the relevant processing procedures when issues arise with the goods. Please be reminded that you can inquire about the approximate cost through the EMS service at the post office.

4. FAQ

1. Issue of Authenticity: If antique or branded goods are found to be counterfeit upon receipt, clear photos showing the differences between the genuine product and the imitation must be provided as evidence. If unable to provide relevant proof, assistance can be sought to find a third-party reputable organization for a premium authentication service .
2. Leaking Iron Teapot: If an antique iron teapot is leaking, please take clear photos of the leaking area and provide them.
3. Transport Damage: If the goods are damaged during international shipping (to the pickup point), you need to provide photos of the outer packaging of the parcel and clear photos of the damaged goods' outer packaging.
