  • This invention relates to a system for projecting bowling scores or other printed matter from a supported sheet which has received printed matter from a printer.
  • projection systems have also been developed for projecting the printed score to a viewing screen.
  • One advantageous such projection system is the prism projector which relies on the internal reflection from prism face to pick up an image for projection to a screen.
  • the bowling sheet can be printed with score information directly on the prism surface with the prism functioning as a printing platen.
  • the sheet is usually provided with a backing transfer substance to produce a visible image on the prism surface for internal reflection and projection.
  • Such prism projecting systems are, for example, described in the following U.S. patents: Roop U.S.Pat. No. 3,249,022, issued May 3, I966; Byrd U.S. Pat. No.
  • the prism projection systems are especially advantageous when used in combination with a printer that can be moved relative to the scoresheet.
  • An advantageous combination of printer and prism projector is described in Pratt, U.S. Pat. No. 3,385,212, patented May 28, 1968, and in Crimmins copending application Ser. No. 563,742, filed Jul. 6, 1966 now U.S. Pat. No. 3,416,443 issued Dec. 17, I968.
  • the disclosures of the Pratt patent and the Crimmins application are hereby incorporated in this application by reference.
  • the present invention provides a new and useful system for holding a sheet in position while projecting printed information from the sheet.
  • a detection system is providedfor detecting the presence of the sheet in properordinationceiving and projection position so that a printer, which can be used to print on the sheet, can be deactivated responsive to absence or improper position of the, sheet.
  • FIG. I is a schematic side view of a system suitable for employing an embodiment of this invention.
  • FIG. 2 is a schematic plan view of the system of FIG. 1;
  • FIG. 3 is an enlarged plan view of a portion of a projection system including the embodiment used in the schematics of FIGS. 1 and 2;
  • FIG. 4 is a side plan view of the embodiment as shown in FIG. 3;
  • FIG. 5 is an enlarged section showing a portion of the paper detection system of the embodiment of FIGS. 3 and 4;
  • FIG. 6 is an abbreviated wiring diagram showing association of switches and elements controlled by the switches.
  • the illustrated system includes printer 12 mounted on pulley wheels 14 supported by rails 16 so that the printer can be moved from a retracted position, to the right as viewed in FIGS. I and 2, to a printing position overlying prism 18 of a prism projector, i.e., to the left as viewed in FIGS. 1 and 2.
  • the prism I8 is provided with a peripheral top frame 22 defining an opening for receiving a score sheet 20.
  • the frame 22 and prism 18 are supported by suitable support or mounting means within the prism projector.
  • a normally open limit switch 24 is mounted on a crossbar between rails I6 at the right ends of rails 16. Switch 24 is closed by the printer when the printer is moved to retracted position. 2
  • a sheet-holding system 26 and a sheet detector system 28 are mounted on plate 22.
  • the sheet-holding system 26 includes a pair of brackets 30 secured to the bottom of frame 22 and extending downwardly.
  • An arm 32 is pivotally mounted by a pivot pin 34 to each bracket 30 and an elongate lift pin 36 extends between and connects the two arms 32 offcenter from pins 34 so that arms 32 pivot as a unit.
  • a clamp plate 38 is also secured at its two ends to the arms 32.
  • One of the arms 32 i.e., to the right in FIG. 3, is provided with an extension 40 (see FIG. 4) which is suitably connected by a pivot pin 42 to a connector arm 44 which is, in turn, pivotally connected by pin 45 to the actuator arm of a solenoid 46.
  • Solenoid 46 is mounted to the bottom surface frame 22 and pulls in when energized and is returned by a return compression spring 48 when solenoid 46 is deenergized.
  • FIG. 4 shows the clamping system in clamping position in full lines and shows the parts moved to unclamping or release position in phantom.
  • Solenoid 46 is energized to move the clamping system from clamping to release position. In clamping position, a sheet of paper 20 supported on prism 18 within frame 22 is held by clamp plate 38 against shifting on prism 18. In order to release the paper, solenoid 46 pulls in and pivots arms 32 to lift the plate 38. The paper can then be removed and replaced with another sheet if desired. On deactuation of solenoid 46, spring 48 urges plate 38 to return to clamping position.
  • solenoid 46 is operated when both switches 24 and 50 are in closed position.
  • Switch 50 is a contact of a printer homing switch which is actuated by a bowler for returning the printer to its retracted position for the purpose of removing the score sheet 20.
  • the printer reaches the retracted position, it closes the normally open switch 24 and plate 38 is immediately moved to paper release position by actuation of solenoid 46.
  • switch 24 opens to deactivate solenoid 46, but if plate 38 does not return to clamping position, plate 38 will be cammed to clamping position by the printer housing during movement of the printer as illustrated by the broken line showing of the printer 12 in proximity to plate 38 in the broken line position in FIG. 4.
  • the paper detector system 28 includes two paper detectors spaced along the clamp plate 38 so that the correct position of the paper can be verified.
  • the paper must be fully under the clamp at both detecting positions so that both paper detectors will detect its presence. If both paper detectors do not detect the presence of the paper, the detector system will indicate an absence or improper position of the paper and render the printer inoperative.
  • each paper detector includes a mounting block 52 secured to the bottom of frame 22 adjacent the score sheet receiving opening.
  • Each mounting block 52 is equipped with a roll pin 54 on which a pair of elongate arms 56 and 58 are pivotally mounted.
  • An integral cross plate portion 60 interconnects each pair of arms 56 and 58 for conjoint move ment.
  • Each arm 58 has an extension 62 and the clamp plate 38 is provided with a separate port 64 for receiving the extension 62 of each paper detector.
  • Each detector is provided with a permanent magnet 70 mounted between arms 56 and 58 on cross plate 60 and carried by the arms as they pivot around roll pin 54 between their full line position and position in phantom in FIG. 4.
  • a reed switch 72 is mounted in mounting block 52 in proper position so that when extension 62 is blocked by the presence of paper 20, magnet 70 is not in alignment with the reed switch 72 contacts and the contacts are closed. However, when a magnet 70 moves to its full line position due to the absence of paper at either port 64, the magnet approaches the contacts of the reed switch 72 and the contacts open. As can be seen in FIG. 6, the
  • the printer includes drive means for moving the printing elements through printing strokes under control of a lrevolution clutch in turn controlled by a solenoid.
  • the reed switches 72 may be in circuit with the printer positioning solenoid such as that at A in U.S. Pat. No. 3,385,212 which functions to engage the l-revolution clutch to initiate printer movement, or in circuit with the printer cycle solenoid such as that at PCS in US. Pat. No. 3,385,212 which functions to energize the l-revolution clutch to initiate a printing cycle.
