Abstract

PURPOSE: To reduce the size and weight of a portable computer device on the whole and to lighten the burden on a user by putting a card, a lid for a battery for operation, and a detecting device, required for data protection, together in one. CONSTITUTION: This device consists of a main body 1, a lid 2, a memory card or I/O card 3, the battery 4 for operation, a lid fixing device 5 which fixes the lid 2, and the detecting device 6 such as a switch which detects the lid fixing device 5 being released. The user operates the lid fixing device 5 when replacing the card 3 or battery 4 for operation of release the lid 2 from being fixed. The detecting device 6 inform an interruption control circuit that the lid fixing device 5 is released. A CPU knows that the lid fixing device 5 is released through the control circuit and performs data protecting operation so that the card 3 or battery 4 for operation may be replaced. Consequently, only one lid 2, lid fixing device 5, and detecting device 6 each are needed, so the device is reduced in size and weight on the whole.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable computer device.

[0002]

2. Description of the Related Art A conventional data protection device for a portable computer device has a detection device for detecting attachment / detachment of a card and an operating battery.

As such a data protection device, there are a memory content protection device for electronic equipment described in Japanese Patent Laid-Open No. 62-121653 and an information processing device described in Japanese Utility Model Laid-Open No. 4-111635.

In the conventional data protection device, each detection device was required, so that the device could not be downsized.

[0005]

SUMMARY OF THE INVENTION In a portable computer device, a detection device and a CPU for detecting the attachment / detachment of a card in order to prevent data from being lost due to noise entering a signal line due to the card being attached / detached while the CPU is operating. In order to prevent the loss of data due to the removal of the operation battery that supplies the electric power necessary for the operation of each of the detection devices, the detection device was provided.

However, since the conventional portable computer devices have their own detection devices, there is a problem that the device becomes large and heavy and the burden on the user becomes heavy.

An object of the present invention is to reduce the burden on the user by combining the card, the lid of the operating battery, and the detection device into one unit to reduce the size and weight.

[0008]

The features of the present invention are, in order to reduce the burden on the user, the card necessary for data protection, the lid of the operation battery and the detection device are combined into one, and the entire device is compact and compact. It is to reduce the weight.

[0009]

Since the data is protected both when the card is replaced and when the operating battery is replaced, there is no problem even if the data is protected by one detecting device.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows the configuration of an embodiment of the present invention. In the portable computer device provided with the data protection device according to the present invention, the main body 1, the lid 2, the memory card or I / O card 3, the operation battery 4, the lid fixing device 5 for fixing the lid 2, and the lid fixing device 5 such as a switch. Is composed of a detection device 6 for detecting that the is released. Further, FIG. 2 shows a block diagram of the main body 1. The main body 1 comprises a detection device 6, a CPU 7, an interrupt control circuit 8, a memory 9, a power supply circuit 10, a data holding battery 11 and a connector 12 for connecting the card 3.

The card 3 is connected to the connector 1 while the CPU 1 is operating.
When it is attached or detached to No. 2, noise may enter the signal line and destroy the data. Further, when the operation battery 4 is removed from the CPU 1, the data writing may not be completed and the data may be destroyed. Therefore, when the card 3 and the operation battery 4 are replaced, it is necessary to put them in a data holding state and then replace them.

When replacing the card 3 or the operating battery 4, the user operates the lid fixing device 5 to release the lid 2 from being fixed. The detection device 6 informs the interrupt control circuit 8 that the lid fixing device 5 has been released. When the CPU 7 knows that the lid fixing device 5 has been released by the control circuit 8, the CPU 7 performs the data protection operation and puts the card 3 or the operation battery 4 into a state in which it may be replaced.

Since only one lid 2, one lid fixing device 5 and one detection device 6 are required, the overall size and weight of the device can be reduced.

[0014]

Since the card, the lid for the operating battery, the lid fixing device, and the detecting device are each provided in one unit, the entire device can be made compact and lightweight, so that the burden on the user can be reduced.
