Module for an integrated circuit system
First Claim
1. A modular electronic device comprising:
- (a) housing means of an insulative material defining an internal chamber, said housing means including parallel planar first and second major surfaces, side walls and end walls;
(b) one of said side walls having an elongated slot of predetermined width extending inwardly along the entire length of the side wall and along adjacent portions of the end walls and communicating with the internal chamber defined by said housing means;
(c) a side wall oppositely positioned from said elongated slot including an integral projection extending therefrom with an outwardly opening recess for receiving an implement to facilitate removal of said housing means from an installed position within an electronic apparatus; and
(d) electronic device means mounted within the internal chamber of said housing means and completely enclosed thereby, said electronic device means including electronic circuit means and a plurality of electrical contacts connected to said electronic circuit means for coupling said electronic circuit means to an external apparatus, said contacts being disposed in substantial alignment with the slot in said side wall of said housing means, said electronic circuit means and said plurality of electrical contacts being accessible from the exterior of said housing means only via the slot in said side wall, the width of said slot being sufficiently small so that the electronic circuit means and electrical contacts are not accessible to a human finger or other object of comparable or larger dimensions, thereby preventing wanton contact and tampering with the electronic circuit means and electrical contacts.

Abstract
A module containing an integrated circuit, such as a read-only memory (ROM), includes an essentially box-shaped plastic housing having an internal chamber in which the integrated circuit is located. Positioned within the chamber is a printed circuit board on which the integrated circuit is mounted. Also mounted on the printed circuit board and adjacent to an elongated narrow slot located in one side of the housing are a plurality of electrical spring contacts electrically connected to the integrated circuit by means of electrical conductors on the printed circuit board. Upon insertion of the module into an electronic apparatus, edge connectors of a printed circuit board of the electronic apparatus extend through the narrow slot and engage the electrical spring contacts, thereby electrically connecting the integrated circuit to the apparatus. The module is designed so that its insertion into and removal from an electronic apparatus is by way of a receptacle which houses the battery power supply for the apparatus. This arrangement requires that the batteries be removed and thus the power disconnected, before the module is insertable into or removable from the apparatus to prevent damage to the integrated circuit from insertion with power on.

6. An electronic apparatus comprising:
-
(a) a receptacle having an opening therein; (b) electrical connector means mounted within said receptacle; (c) a modular electronic device interchangeably disposed within said receptacle, said modular electronic device being electrically coupled to said electrical connector means and comprising; (i) housing means of an insulative material defining an internal chamber, said housing means including parallel planar first and second major surfaces, side walls and end walls; (ii) one of said side walls having an elongated slot formed therein extending inwardly and communicating with the internal chamber defined by said housing means; (iii) the opposite side wall having an integral projection extending therefrom into said receptacle, said projection including an outwardly opening recess for receiving an implement to facilitate removal of said modular electronic device from an installed position within the electronic apparatus; and (iv) electronic device means mounted within the internal chamber, said electronic device means including electronic circuit means and a plurality of electrical contacts connected to said electronic circuit means and being disposed in substantial alignment with the slot in said side wall, said electrical connector means extending through said slot and engaging said plurality of electrical contacts; and (d) power supply means disposed within said receptacle for supplying electrical power to said electronic apparatus, said power supply means being interposed between the electronic module and the opening in said receptacle so as to block insertion or removal of said electronic module into or from said receptacle prior to the removal of said power supply means therefrom. - View Dependent Claims (7, 8, 9)
