A NOVEL CLASS OF DEVELOPMENTALLY REGULATED NON-CODING RNAs IN

An arrangement for safely keeping a stylus as the input unit in the housing of a palm-sized computer contains a guide opening formed in one side of the housing, a stylus holding channel extending from the guide opening towards the inside of the housing for holding the stylus inserted through the guide opening, the cross section of the stylus holding channel being designed to snugly receive the stylus, at least a groove formed on the circumference of the stylus, a resilient strip formed integrally with the inside of the stylus holding channel by cutting the wall of the stylus holding channel, the resilient strip elongated in the direction of the stylus holding channel and having a free end, and a hook projected from the free end of the resilient strip towards the inside of the stylus holding channel, wherein the hook may engage the groove to safely keep the stylus inserted into the stylus holding channel. Preferably, the stylus has more than one grooves so as to be inserted into the stylus holding channel step by step. The arrangement further includes a flange radially formed on the rear end of the stylus, and a slot formed in one side of the housing adjacent to the guide opening as to engage and expose the flange of the stylus completely inserted into the stylus holding channel, whereby the flange may be manually pressed upon retracting the stylus out of the stylus holding channel. The hook contains a radius of curvature the same as that of a groove of a stylus allowing for surfaces, instead of points, to meet when the hook locks into a groove of a stylus.
