Abstract

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.

Claims

1. A battery housing structure for a paging receiver which has a function of alerting a person to reception by causing a motor to vibrate a housing of said receiver, comprising:

a battery container for accommodating a battery;

a generally box-like motor receiving portion provided on an outer side periphery of said battery container and having a recess which is complementary in shape to said motor; and

a cover fastened to said motor receiving portion while covering said motor which is placed in said motor receiving portion, thereby fixing said motor to said receiving portion,

said battery container comprising a side wall provided with a projection which extends perpendicular to a printed circuit board which is built in said receiver, said side wall adjoining a ROM and a label which is bonded to a side wall of said ROM and engraved with a function of said receiver and others, such that said label is visible from the outside of said battery container.

2. A battery housing structure for a paging receiver which has a function of alerting a person to reception by causing a motor to vibrate a housing of said receiver, comprising:

a battery container for accommodating a battery;

a generally box-like motor receiver portion provided on an outer side periphery of said battery container and having a recess which is complementary in shape to said motor; and

a cover fastened to said motor receiving portion while covering said motor which is placed in said motor receiving portion, thereby fixing said motor to said motor receiving portion,

said battery container comprising a side wall which extends perpendicular to a printed circuit board which is built in said receiver, a generally box-like projection extending from a part of said side wall, and a flat metal fitting formed with a threaded hole at a center thereof and a lug at a lower end thereof, said metal fitting being press-fitted in said box-like projection and, at the same time, said lug of said metal fitting being inserted in an opening which is formed through said printed circuit board and then soldered to said board.

3. A battery housing structure for a paging receiver which has a function of alerting a person to reception by causing a motor to vibrate a housing of said receiver, comprising:

a battery container for accommodating a battery;

a generally box-like motor receiving portion provided on an outer side periphery of said battery container and having a recess which is complementary in shape to said motor; and

a cover fastened to said motor receiving portion while covering said motor which is placed in said motor receiving portion, thereby fixing said motor to said motor receiving portion,

said battery container comprising a side wall which extends perpendicular to a printed circuit board which is built in said receiver, said motor receiving portion being molded integrally with said side wall.

4. A battery housing structure as claimed in claim 3, further comprising a cushioning member which is laid in said recess of said motor receiving portion for damping a shock applied to said motor to thereby stably fix said motor in place.

5. A battery housing structure as claimed in claim 3, wherein said cover comprises a thin sheet of metal having a configuration which is complementary to the shape of said motor.
