Abstract

A hand held data entry apparatus wherein a main body portion is formed to be held in one hand while data is entered through a keyboard by the fingers of the other hand. An optical scanning head is mechanically and electrically connected to the main body portion through an arrangement which permits the optical scanning head to be connected to the main body portion in more than one relative position. The scanning head sensor is pointed in a direction such that when the device is held in one hand the other hand may be utilized for entering data through the keyboard and at the same time the scanning head is directed toward the surface to be scanned, without need to reposition the main body portion.

Claims

1. A hand held data entry apparatus comprising:

hand held main body portion for receiving, storing and transmitting information, said main body portion having a major axis;

scanning head including an optical scanning means; and

means for electrically and mechanically connecting said scanning head to said main body portion, said means including an electrical connector having first and second mating contact portions, each including a plurality of contacts, said first mating portion being a part of said main body portion and said second mating portion being a part of said scanning head, said plurality of contacts in at least one of said mating contact portions being connected such that the same electrical connections are made between said first and second mating contact portions irrespective of the orientation of said mating contact portions with respect to each other when they are engaged, said optical scanning means facing in a direction which is at predetermined angle to the major axis of said main body portion, whereby the direction in which the scanning head faces may be oriented with respect to the main body portion to suit the convenience of the user.

2. The hand held data entry apparatus of claim 1, wherein said main body portion includes an electronic memory and a keyboard connected to input information to said memory, said scanning head being connected to said main body portion with the orientation of the connection of said main body portion and said scanning head depending on whether the user operates the keyboard with the fingers of the right or left hand.

3. The hand held data entry apparatus of claim 1, wherein the preferred orientations of the connection of said main body portion and said scanning head is such that the scanning head faces away from the thumb of the operators hand in which the main body portion is held.

4. The hand held data entry apparatus of claim 1, wherein said main body portion is of a rectangular shape, having longer and shorter sides, and is of a size such that said longer sides will fit in the palm of an operator'"'"'s hand between the thumb and fingers, with the said scanning head extending at an angle to the major axis of said main body portion.

5. The hand held data entry apparatus of claim 1, wherein said plurality of contacts are arranged in two parallel rows, with four contacts in each row, the two inner contacts in each row forming an inner set of contacts and the two outer contacts in each row forming an outer set of contacts, with the contacts of the inner set of four contacts being diagonally connected to each other, and with the contacts of the outer set of four contacts being diagonally connected to each other, such that in either of the two possible ways of connecting the first and second mating contact portions, the same contacts in the first and second mating contact portions are electrically connected to each other.

6. The hand held data entry apparatus of claim 1 ,wherein said scanning head includes a printed circuit board though which electrical connections are made between said optical scanning means and said second mating portion.

7. The hand held data entry apparatus of claim 1, wherein said scanning head includes a housing which is provided with means for supporting said optical scanning means and said second mating portion.

8. The hand held data entry apparatus of claim 7, wherein first and second mating securing means are provided on said main body portion and said scanning head housing, respectively, for securing said scanning head to said main body portion.

9. The hand held date entry apparatus of claim 1, wherein said predetermined angle is approximately 60 degrees.

10. The hand held data entry apparatus of claim 1, wherein said optical scanning means is particularly suited for reading bar codes.

11. A hand held data entry apparatus comprising:

a hand held main body portion for receiving, storing and transmitting information, said main body portion having a major axis;

a scanning head including an optical scanning means;

first electrical and mechanical connector means on said main body portion; and

second electrical and mechanical connector means on said scanning head, said first and second connector means being adapted to be joined together in more than one position with respect to each other, such that said optical scanning means may face in at least two different directions with respect to the major axis of said main body portion, the same electrical connections being made between said scanning head and said main body portion without regard to the relative positions in which said scanning head and main body portion are joined together.

12. The hand held data entry apparatus of claim 11, wherein said main body portion includes an electronic memory and a keyboard connected to input information to said memory, said scanning head being connected to said main body portion with the orientation of the connection of said main body portion and said scanning head depending on whether the user operates the keyboard with the fingers of the right or left hand.

13. The hand held data entry apparatus of claim 11, wherein the preferred orientations of the connection of said main body portion and said scanning head is such that the scanning head faces away from the thumb of the operators hand in which the main body portion is held.

14. The hand held data entry apparatus of claim 11, wherein said main body portion is of a rectangular shape, having longer and shorter sides, and is of a size such that said longer sides will fit in the palm of an operator'"'"'s hand between the thumb and fingers, with the said scanning head extending at an angle to the major axis of said main body portion.

15. The hand held data entry apparatus of claim 11, wherein said scanning head includes a printed circuit board through which electrical connections are made between said optical scanning means and said second mating portion.

16. The hand held data entry apparatus of claim 11, wherein said scanning head includes a housing which is provided with means for supporting said optical scanning means and said second electrical and mechanical connector means.

17. The hand held data entry apparatus of claim 11, wherein said optical scanning means is particularly suited for reading bar codes.
