<p>PURPOSE:To enhance mounting density of electronic parts by reducing a battery space on a printed circuit board. CONSTITUTION:A space is inevitably produced among solid electronic parts such as an IC element 2, a chip resistor 5 and a chip capacitor 6 disposed on a printed circuit board 1. By utilizing the space, a thin type or flat square type flexible battery 3 having a height of 1cm of less is disposed in the space. The battery 3 can be detachably connected to an insertion terminal 4 on the printed circuit board 1. Consequently, about 9% of a battery space on the printed circuit board, occupied by the battery can be reduced to as far as 2%. Additionally, the use of the thin or flat square type battery having a height of 1cm or less realizes effective utilization of the space in the vertical direction and enhancement of mounting density of the electronic parts inside equipment.</p> |
