Abstract

In the PC POS terminal unit having both the register function and the totalization/analysis function, a keyboard attached to the unit without wires has two key layouts, one having the JIS key arrangement for the register function on one side and the other having on the opposite side the POS key arrangement for the totalization/analysis function, enabling it to be used either as the cash register or the POS terminal only by turning it over, as required. As shown in the drawing, the keyboard 1 has four openings 2 at the corners on each side which can receive the studs 3 on the terminal unit 4 when the keyboard 1 is placed on the unit 4. One of the openings 2 on each side is provided with a sensor for sensing which side of the keyboard 1 placed on the unit 4 is facing the operator for operation.

Keyboard Equipped With Two Key Layouts

In the PC POS terminal unit having both the register function and the totalization/analysis function, a keyboard attached to the unit without wires has two key layouts, one having the JIS key arrangement for the register function on one side and the other having on the opposite side the POS key arrangement for the totalization/analysis function, enabling it to be used either as the cash register or the POS terminal only by turning it over, as required. As shown in the drawing, the keyboard 1 has four openings 2 at the corners on each side which can receive the studs 3 on the terminal unit 4 when the keyboard 1 is placed on the unit 4. One of the openings 2 on each side is provided with a sensor for sensing which side of the keyboard 1 placed on the unit 4 is facing the operator for operation. At the front edge of the keyboard 1, the terminal 5 is provided for transmitting signals to the unit 4 through the terminals 6 or 7 thereon so that one of the terminals 6 and 7 can meet the terminal 5 when the keyboard 1 is placed on the unit 4. Further, the recess 8 is provided on the unit 4 for preventing the keys on the bottom side of the keyboard 1 placed thereon from coming into contact with the surface of the unit 4.
