In recent years, there has been a potential increase in awareness and sensitivity regarding the abnormal use of data stored on or obtained from data processing machines. In data processing systems in which sensitive data is stored on larger, more sophisticated upper systems and obtained by “powerful” terminal devices, confidentiality protection measures are typically met by appropriate computer programming. For example, the programming requires that a user of the data processing terminal apparatus input one or more code or abbreviated words previously designated in order to access the data stored and processed in the upper system. The abbreviation or code hierarchy should be set up so that different levels can access different levels of sensitivity of the data. To the extent that a terminal for data processing is ineffective (meaning that the device itself cannot process or store data), an unauthorized person operates the device to access data of a higher system, but the person It didn't matter at all because we didn't know the proper abbreviation or access code to actually access the data.

With the advent of data processing devices, such as personal computers, increased data storage and processing capabilities and lower costs, the importance of confidentiality and defense of data stored and processed by data processing systems has been revived.

Personal computers with fixed disk (hard file) storage are now commonly used and have the ability to store large amounts of data and programs that are readily available to users in a working system.

The most basic and obviously most recently recognized solution to the problem of accessibility of intelligent terminal devices, personal computers or sensitive data stored on such a kind provides the ability to access the data and provide access to the room in which the device is installed. It is only to provide the key to authorized persons. While the solution is being implemented in a personal office, for example with one personal computer, there are still several disadvantages to the approach. For example, the solution is relatively expensive, in that the lock (and possibly even the door) needs to be purchased and installed from a non-office owner. Using this form of confidentiality, which should be efficient, the office should be practically locked out at all times when the regular owner is absent, which is the responsibility of another person carrying or collecting mail or other items that normally enter or leave the office during the normal course of the day. Interfere with work. In addition, it may be necessary to limit the period during which other work such as cleaning is performed.

The disadvantage relates to a privately owned thing room. It is desirable for others to have access to all the materials if the room area is large and accommodates multiple people on separate computers, but it is not desirable for any owner in the room to have access to other computers and data entered into them. In this case, the privacy problem becomes more complicated. For this reason, it was necessary to address the problem of data confidentiality in a manner directly related to the data processing apparatus itself, compared to the manipulation of data processing autonomy in a general environment.

Several examples by conventional methods of locking technology for machines, tools and structures will be described. For example, US Pat. No. 3,816,677 shows a locking device externally attachable to a normal toggle switch locking in the off position. US Pat. No. 3,622,720 shows a calculator keyboard cover interlock that causes the calculator switch to not operate when the keyboard cover is closed. U.S. Patent No. 3,971,240, which is mountable to a television set, is inaccessible to the control of the television set in the locked position, i.e., the insulated cover is arranged inaccessible while the channel selector is in the locked position. Describe. Another example of the prior art relating to the safety of an electrical device includes US Pat. No. 4,160,137 for a bracket mountable to a circuit breaker that receives a lock. If a lock appears, do not move the circuit breaker operating handle to the on position. US Pat. No. 4,414,829 describes a lockout device for an electrical instrument box that prevents tampering with electrical instrumentation to alter the record.

The prior art is a locking device that can be easily installed in an office machine such as a personal computer, which presents a combined type of confidential protection in which a locking device is imposed on the machine to lock and protect the current power switch, and the system is locked. None of the locking devices describes the removal of the machine cover and power cord while in the off position. Removal of the machine cover and power cord has an additional hermetic protection feature in that the power switch of the machine cannot be easily bypassed if the cover and the auxiliary power cord cannot be removed.

Therefore, as a device to prevent access of the current mechanical power switch by installing one lock and to lock the cover and the auxiliary power cord to the machine, it is a great advantage to achieve an inexpensive and easy-to-install confidential protection device for office machines. Will be

Thus, when the housing is locked by the lock on the electrical device in which the housing covers the current on-off electrical switch, the current on-off switch is secondly allowed or prevented by removing or removing the outer cover and auxiliary power cord of the device. An apparatus is provided that can electrically bypass the device to prevent unauthorized access to the internal components of the device. The safety of auxiliary power cord plugs and receptacles is essential for machines with switched auxiliary outlets that can power the auxiliary receptacle and operate the machine regardless of the position of the power switch.

In a preferred embodiment of the invention, the bracket is attached to the device to be physically and electrically locked. The bracket is mounted using at least one cover screw or other fastener of the device and is attached with proper access to the current on-off switch. The bracket also has an auxiliary power cord plug restraint to remove unused power from the machine through the auxiliary receptacle by removing the plug of the auxiliary cord from the auxiliary power receptacle of the machine. The housing assembly is then hingedly attached at the bracket. A drawer cylinder lock is mounted in the housing assembly and has a respective rotating cam inside the housing. The cam has a fastening that is securely connected to the bracket to which the housing assembly is hingedly attached, thereby making it impossible to remove the housing assembly while removing the key with the lock in the locked position.

Other objects, features, details, and advantages of the present invention will be described in detail with reference to the preferred embodiments of the present invention by the accompanying drawings.
