- 2. The scrolling display arrangement of claim 1, wherein said drive arrangement moves said web element in first and second directions along the predetermined web path, the motion in the first direction being responsive to the web position signal.
- 3. The scrolling display arrangement of claim 2, wherein said web element has a predetermined web length and there is further provided a fail safe arrangement for preventing excessive effort on the part of said drive arrangement toward moving said web element beyond said predetermined web length.
- 4. The scrolling display arrangement of claim 3, wherein said fail safe arrangement comprises a fail safe deenergization arrangement for discontinuing an effort by said drive arrangement to move said web element.
- 5. The scrolling display arrangement of claim 4, wherein said fail safe deenergization arrangement comprises a programmable timer for discontinuing the effort by said drive arrangement to move said web element after a predetermined period of time.
- 6. The scrolling display arrangement of claim 1, wherein there is further provided a second controller, and said drive arrangement moves said web element in the second direction along the predetermined web path in response to said second control arrangement.
- 7. The scrolling display arrangement of claim 6, wherein said second control arrangement comprises electrical latch means for controlling said drive arrangement to move said web element to a predetermined first information portion.
- 8. The scrolling display arrangement of claim 1, wherein said indexer comprises a position indicator arranged in predetermined relation with respect to said web element for defining a location of said web element having a predetermined relationship to the associated one of the information portions.
- 9. The scrolling display arrangement of claim 8, wherein said web position signal generator comprises a sensor having an electrical output for producing the web position signal in response to a predetermined spatial relationship between said position indicator and said sensor.
- 10. The scrolling display arrangement of claim 1, wherein said drive arrangement comprises an electrical drive, said electrical drive having an electrical terminal for receiving electrical energy from a source of electrical energy, there being further provided an electrical regulator electrically coupled to said electrical terminal for regulating the electrical energy received from said source of electrical energy.
- 11. The scrolling display arrangement of claim 10, wherein the source of electrical energy is an electrical system of a vehicle, the source of electrical energy having a varying voltage characteristic.
- 12. The scrolling display arrangement of claim 10, wherein there is further provided clutch means for mechanically coupling said electrical drive to said web carrier.
- 13. A scrolling display arrangement having a display region comprising:
- a web element having a plurality of sequentially arranged information portions thereon;
- electrical drive means for moving said web element along a predetermined web path whereby the sequentially arranged information portions thereof are viewable in the display region, said electrical drive means having an electrical terminal for receiving electrical energy from a source of electrical energy of a vehicle, the source of electrical energy having a varying voltage characteristic;
- electrical regulator means electrically coupled to said electrical drive means for regulating the electrical energy received from the source of electrical energy of the vehicle;
- web carrier means coupled to said electrical drive means for supporting said web element as it is moved along the predetermined web path, said web carrier means having associated therewith an alignment arrangement for maintaining said web element in a predeterminable spatial relation with respect to the predetermined web path and the display region;
- a gear arrangement coupled to said web carrier means, said gear arrangement having a self-tightening characteristic;
- a clutch for rotatably coupling said electrical drive means to said web carrier means;
- index means coupled to the web element for identifying a location of an associated one of the information portions;
- web position signal generating means for producing a web position signal in response to said index means; and
- control means coupled to said drive means for controlling the motion of said web element in response to the web position signal.
- 14. The scrolling display arrangement of claim 13, wherein said drive means is arranged to move said web element in first and second directions along the predetermined web path, the motion in the first direction being responsive to the web position signal, and there is further provided:
- a programmable timer for deenergizing said drive means whereby motion of said web element in the first direction after a predetermined period of time; and
- rewind means for bypassing said control means whereby said drive means is actuated to move said web element in the second directions along the predetermined web path notwithstanding said web position signal.
- 15. The scrolling display arrangement of claim 13, wherein the vehicle is an electrically powered vehicle of the type having an electrical system, the electrical energy supplied from the electrical system to said electrical regulator means having a voltage characteristic that varies with the operational state of the electrically powered vehicle.
- 16. The scrolling display arrangement of claim 15, wherein the electrically powered vehicle is a golf cart, and there is further provided mounting means for affixing said web carrier means to the golf cart.
