図１に示すように、ＨＤＤ１、警報装置ユニット２、充電式補助電源３が画像形成装置本体Ａの背面側に固定されている。後述する図３に示すように、これらのユニットは画像形成装置本体の外装カバーに被覆されているが、図１では外装カバーを取り外した状態を示している。また、図２に示すように、本体Ａの正面上部には操作部（認証手段）４が取り付けられている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an oblique rear view of an image forming apparatus according to an embodiment of the present invention, and FIG. 2 is an oblique front view of the same.
As shown in FIG. 1, the HDD 1, the alarm device unit 2, and the rechargeable auxiliary power source 3 are fixed to the back side of the image forming apparatus main body A. As shown in FIG. 3 to be described later, these units are covered with an exterior cover of the image forming apparatus main body, but FIG. 1 shows a state in which the exterior cover is removed. As shown in FIG. 2, an operation unit (authentication unit) 4 is attached to the upper front portion of the main body A.

図３は本発明の実施の形態に係る画像形成装置の要部構成を示す断面図であり、（１）は外装カバー装着状態、（２）は外装カバー取り外し（分解）状態を示す。警報装置ユニット２には警報装置センサ５が取り付けられており、（１）に示すように、外装カバー６が本体Ａ（図１参照）側に装着されている状態では、その押圧突起６−１によって警報装置センサ５が押圧されてオフになっている。また（２）に示すように、外装カバー６が分解されると警報装置センサ５から押圧突起６−１が離れ、警報装置センサ５がオンされ、警報装置ユニット２が働く構成となっている。
警報装置センサ５としては、プッシュＳＷ、透過型センサ、インタロックＳＷ等が用いられるが、外装カバー６が分解されたことが検知できるセンサならば何を使用しても問題はない。また、警報装置ユニット２には、サイレン、スピーカ、無線送信装置などが組み込まれており、外部に対して警告することができるようになっている。
通常、画像形成装置本体Ａの電源が投入されているときにはＨＤＤ１、警報装置ユニット２及び操作部４に本体Ａ側から電力供給を行って、充電式補助電源３は充電動作を行っている。しかしながら電源オフや電源コードを抜かれて本体Ａに電力が供給されなくなった場合には、図示しない制御手段（ＣＰＵ）により、ＨＤＤ１、警報装置ユニット２及び操作部４には充電式補助電源３から電力が供給されるようになっており、ＨＤＤ１を外す際に必要な認証処理動作及び警報動作は何ら問題なく行うことができる。
そして上述したように、ＨＤＤ１、警報装置ユニット２、充電式補助電源３は近接配置され、且つ全てが共通の外装カバー６のみで覆われており、ＨＤＤ１、警報装置ユニット２、充電式補助電源３のどれか一つだけ外す場合にも外装カバー６を取り外したり、分解しなければならない構成となっている。
このような構成にすることにより、警報装置ユニット２または充電式補助電源ユニット３だけを先に外され、警報装置ユニット２が動作しない状態でＨＤＤ１を取り外される事態が生じるのを防止することができる。 3A and 3B are cross-sectional views showing the main configuration of the image forming apparatus according to the embodiment of the present invention. FIG. 3A shows an external cover mounted state, and FIG. 3B shows an external cover removed (disassembled) state. An alarm device sensor 5 is attached to the alarm device unit 2, and as shown in (1), when the exterior cover 6 is mounted on the main body A (see FIG. 1) side, the pressing protrusion 6-1. The alarm device sensor 5 is pressed and is turned off. Moreover, as shown in (2), when the exterior cover 6 is disassembled, the pressing projection 6-1 is separated from the alarm device sensor 5, the alarm device sensor 5 is turned on, and the alarm device unit 2 operates.
As the alarm device sensor 5, a push SW, a transmission type sensor, an interlock SW, or the like is used. However, any sensor can be used as long as it can detect that the outer cover 6 is disassembled. In addition, the alarm device unit 2 incorporates a siren, a speaker, a wireless transmission device, and the like so that a warning can be given to the outside.
Normally, when the power source of the image forming apparatus main body A is turned on, power is supplied from the main body A side to the HDD 1, the alarm device unit 2, and the operation unit 4, and the rechargeable auxiliary power source 3 performs a charging operation. However, when the power is turned off or the power cord is disconnected and power is no longer supplied to the main body A, the control unit (CPU) (not shown) supplies power from the rechargeable auxiliary power source 3 to the HDD 1, the alarm device unit 2, and the operation unit 4. The authentication processing operation and the alarm operation necessary when removing the HDD 1 can be performed without any problem.
As described above, the HDD 1, the alarm device unit 2, and the rechargeable auxiliary power source 3 are arranged close to each other and are all covered only by the common exterior cover 6. Even when only one of them is removed, the exterior cover 6 must be removed or disassembled.
By adopting such a configuration, it is possible to prevent a situation in which only the alarm device unit 2 or the rechargeable auxiliary power supply unit 3 is removed first and the HDD 1 is removed while the alarm device unit 2 is not operating. .

また、ＨＤＤ１を外す際に必要な認証処理を行わずに警報装置ユニット２を作動させ、所定の時間が経っても警報装置ユニット２がオフされない場合には、警報装置ユニット２及び充電式補助電源ユニット３より強制的にＨＤＤ１に保存されている内容を消去するように制御手段が制御を行うことで、機密漏洩を防止することができる。
認証処理は本体Ａ正面の操作部４で行われる。認証に際しては、暗証番号の入力、指紋認証等が行われるが、他の本人確認方法を用いても何ら問題はない。認証処理に関しては、電源オフ状態、または電源コードが抜かれている状態でも、充電式補助電源ユニット３からの電力を利用して行うことができるようになっており、本体電源がとれない場所でも認証処理ができるため、ＨＤＤ１を取り外す際に警報装置ユニット２を解除することができる。つまり、操作部４からの操作によって行う認証処理に関しては、充電式補助電源ユニット３からの電力を利用して操作が行えるように構成されている。
また、認証処理後所定の時間内に警報装置センサ５がオンされない場合には、再度認証処理を促し、認証処理者以外の者に外装カバー６が分解されるのを防止することができる。これらの動作及び機構によりＨＤＤ１の盗難が防止できかつ機密漏洩を防ぐことができる。
図４は認証処理動作のフローチャートである。認証処理によって操作が認められた適正な本人であることが確認され（Ｓ１）、所定の時間内に警報装置センサ５がオンされたことが確認されると（Ｓ２）、ＨＤＤ１を取り外すことが可能となる（Ｓ３）。 Further, when the alarm device unit 2 is operated without performing the authentication process required when removing the HDD 1 and the alarm device unit 2 is not turned off even after a predetermined time, the alarm device unit 2 and the rechargeable auxiliary power supply By controlling the control unit to forcibly erase the contents stored in the HDD 1 from the unit 3, it is possible to prevent the leakage of confidential information.
The authentication process is performed by the operation unit 4 on the front surface of the main body A. At the time of authentication, input of a personal identification number, fingerprint authentication, etc. are performed, but there is no problem even if other identity verification methods are used. Respect authentication process, even when the power-off state or power cord is disconnected, and can now be performed using the power from the rechargeable auxiliary power supply unit 3, the authentication also where it is not possible to the body power source Since the process can be performed, the alarm device unit 2 can be released when the HDD 1 is removed. That is, the authentication process performed by the operation from the operation unit 4 is configured to be operated using the power from the rechargeable auxiliary power unit 3.
Further, when the alarm device sensor 5 is not turned on within a predetermined time after the authentication process, the authentication process can be prompted again to prevent the exterior cover 6 from being disassembled by a person other than the authentication processor. With these operations and mechanisms, the HDD 1 can be prevented from being stolen and secret leakage can be prevented.
FIG. 4 is a flowchart of the authentication processing operation. If it is confirmed by the authentication process that the user is an authorized person (S1) and the alarm device sensor 5 is confirmed to be turned on within a predetermined time (S2), the HDD 1 can be removed. (S3).
