Abstract: A Personal Digital Assistant (PDA) with retractable stylus comprises a retractable stylus, a housing, a stylus slot, and a push portion, wherein a contact pad is attached to the inner side of the push portion. The retractable stylus comprises a pen shaft having a release button, a pen body having an opening, and a spring situated inside the pen body. When an external force is applied to the pen shaft downward, the spring is compressed until the opening holding the release button; thus, the stylus is shortened. When the release button is set free from the opening, the spring elasticity ejects the pen shaft upward; thus, the stylus returns to the full-length condition. If the stylus is kept in the stylus slot, an external force applied to the push portion can make the contact pad press the release button; so the pen shaft is ejected upward by spring elasticity.

Abstract: A pressing device for a pen and the pen further comprises a spring, and a center stick fitting with the spring and having a nib part. The pressing device further comprises a penholder, a movable tube, a bounce device, a press cap, and a clipping part. While the clamping piece on the clipping part touches a clipped article, the pen clip is urged to move outward and the clamping piece disengages with the engaging piece. The engaging piece moves upward along the guide slot because of the stretching of the spring and the pressing of the center stick till the stop ring has pressed against the upper opening. Accordingly, the nib part of the center stick may be received in the penholder automatically.

Abstract: A cosmetic pencil containing a cosmetic mass in a thin pencil lead-like configuration. The pencil has a cosmetic mass or crayon-containing sheath and the cosmetic mass may be metered from the pencil by moving a gripping disk inwardly with respect to the sheath. This is done by turning the sheath, by moving it inwardly with respect to the pencil or by pushing a button at the back of the pencil. The mass is forced out of the sheath in a small, metered amount. The cosmetic mass may be cast in the sheath.
