A portable electronic apparatus includes an electronic main unit having a front surface, a rear surface, side surfaces, and a first electrical connector. The electronic main unit is served to perform arithmetic operation. The apparatus further includes a cover member provided on one of the side surfaces of the electronic main unit, for openably covering the front surface of the electronic main unit. The apparatus also includes an electronic sub-unit capable of being coupled with the electronic main unit. This electronic sub-unit has a support portion to be located behind the electronic main unit to support the rear surface, a handle portion projected from side of the electronic sub-unit for supporting the cover member when the cover member is opened, a second electrical connector capable of being connected to the first electrical connector, and an auxiliary electrical device capable of being cooperated with the electronic main unit.
摘要:
A keyboard construction including a metallic flat housing member and a metallic flat key actuator member closely laid upon the metallic flat housing member. The former has apertures in positions to correspond to respective ones of key actuator sections while the latter has cutouts to make respective ones of key actuators formed therein movable in a vertical direction. Key indicia are defined on the tops of the respective key actuators during the etching of the two members.

A pen receptacle for detachably receiving an input pen for use in inputting information into an information processor includes a processor housing having a chamber defined therein for receiving the input pen, a retaining member for retaining the input pen inside the chamber, a locking member for locking the retaining member at a predetermined position where the input pen is retained inside the chamber, and a spring for biasing the retaining member in a direction required for the input pen to be ejected out of the chamber. By this construction, the input pen can be easily removed out of the chamber merely by pushing the input pen locked at the predetermined position.

A switch including a springy metallic sheet having a plurality of integrally formed domed members, and a force removing or absorbing element provided within the sheet. The domed members are provided by pressing at a plurality of predetermined positions of the sheet. The force removing or absorbing element includes first slits provided at the peripheral portions of the domed members and second slits provided within the domed members. The slits are provided for removing or absorbing the force caused by the movements of the domed members and for preventing the influence of force to adjacent key portions, and/or for controlling the operating load upon the top of the domed member.
摘要:
An upper member of a housing and a plurality of key actuators are unified into a single flat sheet made of stainless steel. The respective key actuators are made movable by providing a "U" shaped slot and a hinge at the corresponding limited regions of the stainless steel sheet. The hinge and key indicia are formed at the same time by a half etching step. When a particular one of the key actuators is actuated, a movable contact on a conductive silicon rubber sheet will come into contact with a stationary contact on a circuit board.

摘要:
A thin electronic apparatus comprises as its primary structural components a substrate carrying key counter contacts and a first wiring pattern thereon, and an elastic sheet carrying key symbols on one surface thereof and a second wiring pattern on the other surface thereof. The thin electronic apparatus consists primarily of the substrate bonded to the elastic sheet and electronic components housed in cavities in the substrate.

A substantially thin keyboard for use in credit card sized clock calculators or the like includes a rigid plate carrying a plurality of stationary key contacts, a flexible member integral with a plurality of electrically conductive rubber movable contacts and a keyboard surface member, all of which are stacked in the named order. An indicia sheet is interposed between the flexible member and the keyboard surface member, which carries a plurality of groups of key indicia or markings. A slide switch is movably attached so as to shift the key indicia carried on the sheet in relation to the plurality of the stationary key contacts group by group. Masking members are secured on part of the keyboard surface member to conceal all the groups of the key indicia from view other than one group of the key indicia is presented in register with the stationary key contacts.
摘要:
An upper member of a housing and a plurality of key actuators are unified into a single flat sheet made by stainless steel. The respective ones of the key actuators are made movable by reducing the thickness of the corresponding limited regions of the stainless steel sheet. When a particular one of the key actuators is actuated, a movable contact on a conductive silicon rubber sheet will come into contact with a stationary contact on a circuit board.
