Abstract

A system made up of a portable information terminal mountable on a shopping cart for providing product and advertising information while the cart is moved inside a store and an external memory device connectable to the portable information terminal, the external memory device including a memory housing, a non-volatile memory storing data in the memory housing, and a first electrical connector projecting from the housing for allowing a processor to access the stored data; the portable terminal including a terminal housing including a display, a processor in the terminal housing for causing the display to display product information and advertisements, and a second electrical connector inside the housing complementary to the first electrical connector for connecting an external memory device to the processor, the terminal housing including a passage providing access to the second electrical connector from outside the terminal housing and at least one door recessed in the passage shiftable from a first position blocking the passage to a second position by inserting the external memory device into the passage.

Claims

1. A system comprising a portable information terminal mountable on a shopping cart for providing product and advertising information while the cart is moved inside a store and an external memory device connectable to the portable information terminal,

the external memory device comprising:

a memory housing;

a non-volatile memory storing data in the memory housing; and

a first electrical connector projecting from the housing for allowing a processor to access the stored data;

the portable terminal comprising;

a terminal housing including a display;

a processor in the terminal housing for causing the display to display product information and advertisements; and

a second electrical connector inside the housing complementary to the first electrical connector for connecting an external memory device to the processor;

the terminal housing including a passage providing access to the second electrical connector from outside the terminal housing, and at least one door recessed in said passage shiftable from a first position blocking said passage to a second position by inserting the external memory device into the passage.

2. The system of claim 1 wherein said memory housing has a cross sectional shape and said passage has a shape complementary to said cross sectional shape for slidably receiving said memory housing.

3. The system of claim 1 including a latch shiftable between a latched position preventing said at least one door from shifting from said first position to said second position and an unlatched position allowing said at least one door to be shifted from said first position to said second position.

4. The system of claim 3 wherein said latch includes an actuating portion projecting into said channel.

5. The system of claim 4 wherein said memory housing includes a portion for engaging said actuating portion.

6. The system of claim 4 wherein said latch includes an actuating portion on said at least one door.

7. The system of claim 5 wherein said actuating portion is positioned to be actuated by said first electrical connector when said memory device is inserted into said passage.

8. The system of claim 1 including at least two latches each shiftable between a latched position preventing said at least one door from shifting from said first position to said second position and an unlatched position allowing said at least one door to be shifted from said first position to said second position.

9. The system of claim 1 wherein said at least one door is spring biased toward said first position.

10. The system of claim 3 wherein said memory housing includes a projection adjacent to said first electrical connector for shifting said latch to said unlatched position.

11. The system of claim 1 wherein said at least one door comprises first and second doors.

12. A portable information terminal mountable on a shopping cart for providing product and advertising information while the cart is moved inside a store comprising:

a housing including a display;

a processor in the housing for causing the display to display product information and advertisements;

an electrical connector inside the housing for connecting an external memory device to the processor;

the housing including a passage providing access to the electrical connector from outside the housing, and at least one door recessed in said passage and shiftable between a first position blocking said passage and a second position by inserting an external memory device into the passage.

13. The portable information terminal of claim 12 wherein said at least one door comprises at least one door hingedly connected to the housing.

14. The portable information terminal of claim 13 including a latch shiftable between a latched position preventing said at least one door from shifting from said first position to said second position and an unlatched position allowing said at least one door to be shifted from said first position to said second position.

15. The portable information terminal of claim 14 wherein said latch includes an actuating portion projecting into said channel.

16. The portable information terminal of claim 14 wherein said latch includes an actuating portion on said at least one door.

17. An external memory device usable with a system comprising a portable information terminal mountable on a shopping cart for providing product and advertising information while the cart is moved inside a store and an external memory device connectable to the portable information terminal,

the external memory device comprising:

a memory housing;

a non-volatile memory storing data in the memory housing;

a first electrical connector projecting from the housing for allowing a processor to access the stored data; and

a projecting member projecting from said memory housing adjacent to said first electrical connector.

18. The external memory device of claim 17 wherein said projecting member has a cross section selected to correspond to the cross section of an opening in an information terminal with which the external memory device is to be used.

19. The external memory device of claim 17 wherein said projecting member is retractably mounted on the memory housing.

20. The external memory device of claim 19 including a slide for retracting said projecting member.
