Antique japanese Electronic device

I acquired an antique Japanese electronic device. I have two pages of information about it in a jpeg image file. I would like to get it translated so I know what the device is. It does not need to be a professional translation. Can anyone help? Thanks.

If you could post the image on a free photo-sharing website like Flckr, and copy and paste the URL of that page here, forum members can have a look :)

Here is the link to flicker that has photo's of the device and the paperwork that was with it. Thanks!

Oh my, this must be a practice unit for code transmitter... seriously old, with the writing all in old kanji and in old-fashioned writing...

I was told it was from the 1920's but I am not sure if that is right. It would be great if someone could tell who the manafacturer was and what the device was called. Of course any translation of the attached papers would be greatly
appreciated. I lived in Japan for seven years. I collect antique radio equipment so this item has a special meaning to me.

It says:

According to this website, they don't list the current name for the manufacturer, so it may be that the company no longer exists.

This is a page about collectors of telegraphic keys around the world, and toward the bottom one Japanese man by the name of Seisaku Nishida is mentioned, along with a photo of probably the same machine.

Since I was translated in translation software, I do not know what could be successfully translated.
The translation is wrong, please correct.

九九式電信符練習機取扱い方法

1.電源切断器が「断」の位置にあるかどうかを確かめる。
2.真空管を所定の位置に挿入する。
3.供給する電源に応じ、電源端子に誤りがないよう電気の紐の接続をする。
この場合、供給電源が交流100Ｖまたは直流100、あるいは220Ｖであるかに充分な注意を払い、直流の場合は極性を誤らぬよう、それぞれ所定の端子に電紐を接続する。
4.受聴器を所定の位置（受聴器端子）に接続する。
受聴器端子は正面及び裏面に各１組ずつある。
5.電鍵は電鍵接続端子に接続する。（正面にある）
6.供給電源に応じ電源切断器を操作する。
（例）供給電源が交流の場合には電源接断器の取っ手を交流側に倒し、直流の場合には（100Ｖ及び220Ｖをも含む）電源接断器の取っ手を直流側に倒す。
電源接断器操作後おおむね20秒にして本機は動作状態となる。
7.電鍵を操作することにより目的の符号を練習することができる。
8.音量は音量調整器により適当に調整する。
本機は受聴器１０個を並列に接続した場合最大約「2Ｖ」の出力ができる。
9.音調は周波数転換器により「８００サイクル」「１０００サイクル」及び「１２００サイクル」の任意の周波数に切り換えて使用する。
10.使用しない場合、電源接断器は必ず「断」の位置に戻して置く。

1. it is sure whether the power cutter is in the position of "OFF（断）".
2. it wants to insert the tube in place.
3. Depending on the supply power, the connection of the electrical cord so that there is no error in the power supply terminal.
In this case, to pay sufficient attention to whether the power supply is an AC 100V or DC 100 or 220V,, the case of direct current so as not to err polarity, respectively to connect the Denhimo to a given terminal.
4. it will be connected to a predetermined position a listening device (listening device terminal).
Listening device terminal is one by one set each on the front and back.
5. telegraph key connected to the telegraph key connection terminal. (In the front)
6. to operate the power cutter depending on the power supply.
(Example) down to the AC side of the handle of the power supply disconnection device in case the power supply is AC, in the case of direct current (including the 100V and 220V) to defeat the handle of the power connecting and disconnecting device on the DC side.
Power disconnection device operation after approximately this machine in the 20 seconds in an operating state.
7. It is possible to practice sign of interest by operating the telegraph key.
8. volume appropriately adjusted by the volume regulator.
This machine can output up to about "2V" If you connect a listening device 10 in parallel.
9. tone is used by switching to any of the frequency of "800 cycle" "1000 cycle" and "1200 cycle" by the frequency conversion device.
10. If you do not use, and put them back the power supply disconnection device is always in the position of "OFF(断）".

You guys are awesome!!! I can not thank you enough! Now I have a good start to finding a lot more information about this device. I couldn't have done it without you. Thank you so much!

One last question. I believe on the front of the box it has a plate that has the date that this was manufactured. Can anyone tell me what that date is? Thanks.

With the reflection I cannot tell. The year and the month (as well as the serial number on the line above) are printed or embossed on the silver-color parts.

I can not read the numbers in the picture.
Since the products have been exhibited in the Internet auction was a 1943(Shouwa juhachi nen,昭和18年） made, perhaps I suspect whether 1941-1945(昭和16年,shouwa juroku nen-昭和20年,shouwa niju nen）.
During the Second World War.

Since the era shown is Showa 昭和 and the address is still Tokyo-shi 東京市 instead of Tokyo-to, the date is at least definitely between 1926-1943.

I added a new close up photo of the label. Maybe you can see the date now clearly.

Serial number [1013]
Showa [17] year (1942), [3] month (March)

Thank you so much! That is exactly the information I needed. You all have been a huge help. I really appreciate it.
