Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to an information processing device that operates on a battery. In recent years, with the demand for smaller and lighter equipment, packed batteries are being used as power sources. It is now possible to stay. However, with a device configured like this, the battery may run out unexpectedly. If removed, the data stored in volatile memory may be lost or the If the data is being processed, do not start processing again from the beginning after installing or replacing the battery. There are some inconveniences, such as having to do this, and countermeasures are required.

0002

[Conventional technology]

In information processing equipment such as notebook computers, word processors, and handheld terminals. If the battery is removed, in order to guarantee the equipment status, the power supply must be turned off when the equipment is not processing. Alternatively, as shown in the perspective view of FIG. 5 and the side view of FIG. A convex portion 4 is provided at the tip of the cover 3 that covers the battery 2 housed in the device 1. The switch 5 is equipped with a switch 5, and two batteries are connected by pressing or not pressing the switch 5 by the protrusion 4. When the cover 3 is removed, the detection output of the switch 5 determines whether the cover 3 is attached or not. The system was configured to perform security processing for the status of the computer.

0003

[Problem that the idea aims to solve]

In a device configured as above, cover 3 must be removed during normal battery removal work. To take out battery 2 after removing it, for example, remove cover 3 and then take out battery 2. The data recorded in volatile memory (RAM) up to this point is transferred to non-volatile memory (EE). PROM) or during processing, the battery may need to be replaced due to a drop in battery voltage. If this occurs, save the results in progress to non-volatile memory at the above-mentioned time, and then turn off the power. It is possible to read the pool replacement save data and restart the process.

0004 However, if the device is accidentally dropped, the cover can easily come off and the battery can be ejected. If this happens, the power will be momentarily cut off at the same time as the battery is detected to have fallen out, so it is not possible to perform security processing. I couldn't do it.

[0005] For this reason, the cover is usually fixed to the device body using screws, etc. to prevent it from coming off easily. However, when replacing the battery, it may be necessary to carry out warranty processing due to the fall. did not come.

[0006] In view of the above issues, this invention prevents instantaneous power outages and protects the memory. The purpose is to prevent data loss.

[0007]

[Means to solve the problem]

In the present invention, as shown in the perspective view of FIG. a cover 6 for covering, a fixing means (fixing screw) 7 for fixing the cover 6 to the device main body 1; A detection means (detection switch) 8 for detecting the degree of fixation of the fixing means 7 and a battery 2. It is equipped with operating parts 14, 15, 16, and 17 (not shown) that operate depending on the voltage supplied from the The operating parts 14, 15, 16, and 17 are controlled depending on the output of the detection means 8. It is something.

[0008]

[Effect]

When removing the battery, remove the fixing screw to remove the cover. Then, the detection switch is activated, and the control section stores the memory in the time until the battery is removed. Measures can be taken to protect data.

[0009]

【Example】

In the present invention, as shown in the perspective view of FIG. 1 and the side view of FIG. A cover 6 that covers the battery 2, a fixing screw 7 that fixes the cover 6, and a fixing screw 7 that fixes the cover 6. It is equipped with a detection switch 8 that is activated by attachment and detachment.

0010 That is, the cover 6 is a pack containing the battery 2, and the tip of the cover 6 has a A convex portion 10 is provided with a screw hole 9 for a fixing screw 7. Therefore, when the cover 6 is inserted into the device 1, as shown in the enlarged view of the main part in FIG. is located above the detection switch 8.

[0011] When the fixing screw 7 is inserted through the hole 11 of the device 1 and screwed into the screw hole 9, the cover 6 is fixed to the device 1. At the same time as the cover 6 is fixed, the tip of the fixing screw 7 is exposed to the protruding part of the detection switch 8. Press down the head 8a to turn on the detection switch 8.

0012 The head 8a of the detection switch 8 is biased by the coil spring 12, protrudes, and is fixed. It is configured to be retracted by the tip of the screw 7. When the detection switch 8 is turned on, the switch detection circuit turns on, as shown in the block diagram of FIG. The control unit 14 confirms that the battery 2 is installed in the device 1 and determines that the battery 2 is installed in the device 1. Cause the device to perform an action.

[0013] Conversely, when removing the battery 2, the cover 6 must be removed first; For this purpose, the fixing screw 7 must be removed. When the fixing screw 7 is loosened by a predetermined length and the tip is separated from the detection switch 8, the detection switch The switch 8 turns OFF, the switch detection circuit 13 detects this, and the control unit 14 detects that the battery 2 is turned OFF. At the same time as recognizing that it is about to be removed, the RAM→ Instructs the EEPROM transfer circuit 15 to transfer the data recorded in the RAM 16 to the EEPROM. Take measures to transfer to 17.

[0014] This means that even if the tip of the fixing screw 7 separates from the detection switch 8, it will not come off the cover 6. It takes more time for the controller 14 to take memory protection measures. It is possible because it is possible.

[0015] In this example, the battery and cover are attached as one unit. However, the battery cover may be configured to be attached individually to each battery cover. In addition, in this embodiment, data in RAM is simply saved to EEPROM. However, due to a voltage drop in the battery while the device was processing data, the battery had to be replaced. The operator will be notified of the need and will be able to stop the process, replace the battery, and then resume the process. Alternatively, the intermediate processing results may be saved in the EEPROM.

[0016]

[Effect of the idea]

This invention prevents instantaneous power outages, protects memory, and protects data. This makes it possible to prevent data from disappearing. Also, the fixing screws ensure that the battery is securely attached to the device. It has great economic and industrial effects, such as being fixed in place and preventing unintentional falling off. do.
