In an information processing system having a portable terminal unit, such as a hand-held computer, driven by a rechargeable battery and a data communication adaptor for enabling communication between the portable terminal unit and a host computer of the system, the terminal unit and the data communication adaptor are designed to minimize the size thereof in the following five ways. First, a memory card holding mechanism for connecting the memory card of the portable terminal unit is provided between a swinging back lid and a recess of the back casing. Second, a normal interface and a high-speed interface are both provided in the portable terminal unit and the the data communication adaptor respectively. Third, an auxiliary connector for an optional device to extend a function of the portable terminal Unit is provided in the opening of the casing of the portable terminal unit movable in three dimensions mounted on a printed circuit board. Fourth, a moisture resistant seal made of rubber or resin is molded integrally onto one of the joining edges of an upper casing and a lower casing. Fifth, an electric power source portion of the data communication adaptor is used not only for charging the battery of the portable terminal unit but also supplying a power adequate for enabling a data transmission operation thereof.

In an information processing system having a portable terminal unit, such as a hand-held computer, driven by a rechargeable battery and a data communication adaptor for enabling communication between the portable terminal unit and a host computer of the system, the terminal unit and the data communication adaptor are designed to minimize the size by having an auxiliary connector for an optional device extend a function of the portable terminal unit. This is provided in the opening of the casing of the portable terminal unit movable in three dimensions mounted on a printed circuit board.

A bar code reader using a high speed scanner, containing: a scanning unit scanning a surface on which a bar code is printed; a bar width detecting unit successively detecting widths of bars; a bar width storing unit storing the widths; an address generating unit generating an address of the bar width storing unit at which each of the widths is to be stored; a fast screening unit determining whether a set of widths successively detected by the bar width detecting unit satisfies a predetermined condition for the set of widths constituting a complete bar code; and a bar code decoding unit reading a set of successive widths from the generated address, and decoding the bar code determined by the complete bar code detecting unit. A type of bar code detecting unit detecting a type of bar code constituted by the detected widths, and an address & type storing unit storing the detected type of bar code, together with information on the generated addresses for the widths of the bar code, may be inserted. The bar code decoding unit contains specific type decoding units for respectively decoding types of bar codes. The bar code decoding unit reads the stored widths from the addresses indicated by the information stored in the address & type storing unit, and decodes the bar code using one of the specific type decoding unit corresponding to the type stored in the address & type storing unit together with the above information.
