发明名称 Battery casing for a paging receiver
摘要 A paging receiver having a function of alerting a person to reception by causing a motor to vibrate a housing of the receiver is disclosed. A generally box-like motor receiving portion is positioned on the outer side periphery of a battery casing and provided with a recess which is complementary in shape to a motor. A cover is positioned to cover the motor, which is placed in the motor receiving portion, and fastened to the motor receiving portion to fix the motor to the same portion. The battery casing includes a side wall which is shaped flat complementary to a ROM, and is made of a semi-transparent material, so that a ROM function label is visible from the outside merely by removing a battery cover. A flat metal fitting is press-fitted in a box-like projection which extends from a part of the side wall of the battery casing, whereby the printed circuit board and the battery casing are rigidly connected together.
