A battery storage apparatus for a portable electronic device is provided which includes a battery storage chamber formed in a casing of the portable electronic device and a storage chamber cover. A guide rail is formed on the casing. A guide groove is formed in the storage chamber cover and engages the guide rail to allow the storage chamber cover to slide on the guide rail when the storage chamber cover is installed on or removed from the casing. A recess is formed in the guide groove. A protrusion is formed on the guide rail and fitted into the recess to hold the storage chamber cover from moving along the guide rail when the storage chamber cover is installed on the casing completely, thereby avoiding dislodgment of the storage chamber cover from the casing even if the portable electronic device undergoes undesirable physical impact.

Battery storage structure for portable electronic device

A printed circuit board with an electronic component and a wiring pattern is fixed in a casing. A static electricity removing member is provided at an edge of the printed circuit board adjacent to an inlet of the casing through which static electricity inters into the casing. Preferably, the static electricity removing member is a throughhole-like or semi-circular conductive member with opposed sharp edges electrically connected to a ground terminal via a resistor or a low-pass filter.

Static electricity removing structure for portable electronic devices

A carrying case for portable electronic equipment is provided which is designed to allow a case carrier to stop an alarm or call sound produced from the electronic equipment without opening the carrying case. The carrying case has a protrusion formed on an inner wall of a cover at a given interval away from an operating button on the electronic equipment disposed within the carrying case. The cover is supported elastically by a case body with a given gap between front edges of the cover and the case body. The depression of the operating button of the electronic equipment through the protrusion to stop the alarm or call sound is achieved by pressing one of the cover and the case body against the other to decrease the gap therebetween. In another modified form, a window is formed in the bottom of the case body for allowing the case carrier to move the electronic equipment within the case body using a finger load, thereby bringing the operating button into engagement with the protrusion on the inner wall of the cover.
