In a battery loading and unloading mechanism, a battery formed in a flat rectangular parallelepiped and having an almost square main surface is loaded and unloaded to and from a device. The battery is formed with projecting portions at longitudinal both ends of a back surface thereof and along the back surface, whereby the battery can be prevented from being erroneously inserted into the device. The projecting portion has an inclined surface acutely inclined with respect to the back surface, and when the battery is unloaded from the device, unloading of the battery from the device is accelerated by the inclined surface undergoing contact pressure of the retaining means. The device is formed with a notched portion which is adapted to expose the other projecting portion of the battery when the battery is loaded, thereby facilitating unloading of the battery.
A flat almost-rectangular parallelepipedic battery which is formed with a back frame portion and a first side surface connected to and substantially perpendicular to the back frame portion, the back frame portion having a thickness extending towards an insertion surface of the battery, the back frame portion also having first and second projecting portions having different shapes from one another located at both longitudinal ends of the back frame portion and being within the thickness of the back frame portion, the first and second projecting portions being located in a plane substantially perpendicular to the first side surface, the back frame portion being opposite to the insertion surface of the battery inserted into a device.
A flat almost-rectangular parallelepipedic battery which is formed with a back frame portion having a thickness extending towards an insertion surface of the battery, the back frame portion having first and second projecting portions having different shapes from one another located at both longitudinal ends of the back frame portion and being within the thickness of the back frame portion, the back frame portion being a surface opposite to the insertion surface of the battery inserted into a device, the insertion surface including projecting portions having different shapes from one another projecting in an inserting direction at both end portions of the insertion surface.
A flat almost-rectangular parallelepipedic battery which is formed with a back frame portion and a first side surface connected to and substantially perpendicular to the back frame portion, the back frame portion having a thickness extending towards an insertion surface of the battery, the back frame portion also having first and second projecting portions having different shapes from one another located at both longitudinal ends of the back frame portion and being within the thickness of the back frame portion, the first and second projecting portions being located in a plane substantially perpendicular to the first side surface, the back frame portion being opposite to the insertion surface of the battery inserted into a device, the insertion surface including projecting portions having different shapes from one another projecting in an inserting direction at both end portions of the insertion surface.
