<p>PURPOSE:To surely perform the data save processing by providing a data save processing means which performs the data save processing at the time of detecting the start of unloading of a battery cassette. CONSTITUTION:A battery cassette 2 and electrodes 3a and 3b are provided, and these electrodes are provided in the battery cassette storage part of a device main body 1 and are slided for a fixed length to keep a battery connected at the time of loading/unloading of the battery cassette 2 to/from the device main body 1. A battery cassette loading/unloading detecting means 8 detects loading/unloading of the battery cassette 2, and the data save processing means performs the data save processing when the start of unloading of the battery cassette 2 is detected by a loading/unloading detecting means 8 of the battery cassette 2. Though the unloading operation of the battery cassette 2 is continued during the data save processing, the battery cassette 2 and electrodes 3a and 3b provided in the battery cassette storage part of the device main body 1 are slided by only the fixed length up to the end of the unloading of the battery cassette 2 and are kept electrically connected. Thus, the sufficient data save processing time is secured.</p> |
