Abstract

Battery side terminals disposed on the first and second battery devices are arranged at the same places at front surfaces with respect to lower surfaces and side surfaces. On the front surface of a case of the second battery device, there are formed engaging recessed parts. Positions close to the lower surface of the engaging recessed parts are formed as flat surfaces parallel to a upper surface and the lower surface. The dimensions from the lower surface of the case to flat surfaces and the dimension from the lower surface of the case of the first battery device to an upper surface are configured to be the same. Accordingly, it is possible to provide an advantageous battery device that allows the use of battery devices having various capacities and improves the ease of use.

Claims22

Dependent claims

A battery device housed in a single battery housing chamber of an electronic device, comprising:

a case having side surfaces located on both ends of a width direction, an upper surface and lower surface located on both ends of a thickness direction, and a front surface and a rear surface located on both ends of a length direction;
a charging unit fixed inside the case;
and
a battery side terminal disposed on the front surface of the case and connected to the charging unit, the battery side terminal configured to connect to a housing chamber side terminal of the electronic device to provide electric power to the charging unit from the electronic device as said charging unit charges and to provide electric power from the charging unit to the electronic device through the battery side terminal as the charging unit discharges,
wherein a first engaging recessed part is formed on the front surface of the case of the battery device and a second engaging recessed part is formed on the front surface of the case of the battery device, the first and second engaging recessed parts being separated in the width direction by a gap.
