A butterfly clip removably mounted on a paging receiver or like portable equipment is made up of a support section which comprises a molding of plastics, and a clip section constantly biased by a coil spring, which is received in the support section, and openably held by the support section through a spring pin. The support section is shaped complementary to the contour of the equipment. The housing of the equipment is formed with a slit-like recess on its top and a generally L-shaped recess adjacent to its lower end. On the other hand, the support section of the clip is provided with projections at the top of its inner wall which mates with the recess provided on the top of the housing, and a generally J-shaped metal member at its lower end which mates with the recess provided in the lower portion of the housing. The clip is easily attached to and detached from the housing by, respectively, mating the metal member of the support section with the recess of the housing and removing the support member from the housing using the elasticity of plastics.

Removable clip for portable equipment

A paging receiver to which various extra functions may be selectively added. A receiver body of the paging receiver has a miniature and thin configuration and is provided with only a sound type alerting function. Minimum necessary degrees of receiving function, antenna function, speaker function and power psupply function are furnished with in the receiver body. A holder adapted to hold the receiver body is provided with advanced functions a well as a vibrator function and other extra functions. Only when the holder is combined with the receiver body, it allows the receiver to exhibit the advanced functions or the extra functions as desired. In order that the receiver body and the holder may be fixed to each other when combined, a housing of the receiver body and the holder are individually provided with mating portions and electrical connecting terminals.

Holding structure for a paging receiver having extra functions

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.
