Abstract

PURPOSE:To continue the electricity supply to a printed substrate even at battery replacing time by separating a first electrode in an old case from a second electrode of a main body after bringing a first electrode of a new battery case into contact with the second electrode of the main body in the case that a main battery case is replaced while mutual reaction of a first and a second parts are maintained. CONSTITUTION:A first guide part 100 of a battery case and a second guide part 400 of a main body are engaged each other to fix the case 300 in the main body 600 and at the same time a first electrode 200 of the case 300 and a second electrode 500 of the main body are brought into contact with each other to supply electricity to a printed substrate 1000 from a battery 900. In other words, while a second lock system part 800 of the main body 600 being pushed downward the old case 300 is pushed backward by a new case 300' and the cases 300, 300' are slid by the mutual reaction of the first and the second guide parts 100, 400. Then, the system part is separated and the case 300' is continuously pushed to bring its first electrode 200 into contact with the second electrode 500 in the main body and the first electrode 200 of the old case 300 is separated from the second electrode 500 of the main body.

Therefore, the power supply to the printed circuit board 42 is not cut off when replacing the battery. Furthermore, if you keep pressing the new battery case 21' and slide it to the top of the device body 31, the old battery case 2
1 is ejected, and at the same time the locking members 38 and 39, which are biased by the spring 43, are inserted into the new battery case 21'.
The device is automatically locked to the main body 31 by latching into the lock grooves 29 and 30 of the device.

In the above embodiment, four spring-like electrodes 34 to 37 are provided on the main body 31 of the device, but a larger number of spring-like electrodes may be provided, or even one spring-like electrode may be provided.
It is also possible to make the electrodes longer and provide one long spring-like electrode along each guide rail 32, 33.

Further, contrary to the above embodiment, spring-like electrodes 34 to 37 are provided on the battery case 21, and the device main body 31
The plate-shaped electrodes 27 and 28 may also be provided. Also, with the same idea, the guide rail 3 is attached to the battery case 21.
2 and 33, and guide grooves 25 and 26 may be provided in the main body 31 of the device.

Further, the number and cross-sectional shape of the guide rails and guide grooves are not limited as long as they can restrict vertical and horizontal vibration of the battery case 21. Furthermore, if the guide rail and guide groove themselves are used as electrodes, it can be used in even more compact portable devices.
