Abstract
Abstract A device for projecting bowling scores and the like including a support surface, e.g., the prism face of a prism projector, for supporting a score sheet during projection, operable holding or clamping means, for clamping the sheet in proper position on the surface, and detection means for detecting the presence of the sheet in proper clamped position. A printer can be mounted for movement relative to the support surface between a retracted position removed from the surface and a printing position overlying the surface and the printer can be automatically shut off or rendered inoperable responsive to a ''''paper absent'''' condition as detected by the detection means. The clamp can be moved to an unclamping position responsive to movement of the printer to retracted position, e.g., by limit switch actuation of a solenoid. The clamp can also be arranged to be moved to clamping position responsive to movement of the printer to printing position, e.g., by camming action of the printer housing.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
136 words
A device for printing on a sheet comprising means defining a support for the sheet, means for detecting the presence or absence of the sheet on the support, printer means operative for printing on said sheet, drive means for operating the printer, means responsive to detection of the absence of the sheet by said detecting means for rendering said printer drive means inoperative, wherein each the detector comprises and arm means mounted on the support eccentric to its center of gravity for pivotal movement about a horizontal axis and having one end heavier than the other, feeler means at one end of said arm means engaging said sheet under gravity urging from the weight of the heavier end of said arm, and means adjacent the position of engagement holding said sheet against movement by the arm.
Claim 2
Independent Claim
136 words
A device for printing on a sheet comprising means defining a support for the sheet, means for detecting the presence or absence of the sheet on the support, printer means operative for printing on said sheet, drive means for operating the printer, means responsive to detection of the absence of the sheet by said detecting means for rendering said printer drive means inoperative, wherein each the detector comprises and arm means mounted on the support eccentric to its center of gravity for pivotal movement about a horizontal axis and having one end heavier than the other, feeler means at one end of said arm means engaging said sheet under gravity urging from the weight of the heavier end of said arm, and means adjacent the position of engagement holding said sheet against movement by the arm.
Claim 3
Dependent Claim
77 words
The device of claim 1 wherein said detection responsive means comprises a magnet on one end of the arm and a reed switch controlling the printer drive means and mounted in position with its contacts out of the influence of said magnet with the feeler means engaging said sheet so that in the absence of the sheet the arm pivots the magnet to approach the contacts to actuate the reed switch and disable the printer drive means.
Claim 4
Independent Claim
141 words
A device for printing on a sheet comprising means defining a support for the sheet, means for detecting the presence or absence of the sheet on the support, printer means operative for printing on said sheet, drive means for operating the printer, means responsive to detection of the absence of the sheet by said detecting means for rendering said printer drive means inoperative, wherein said detecting means comprises a movably mounted member engageable with a sheet properly located on the support surface, means yieldably biasing the member to a first position engaging a sheet properly located and to a second position in the absence of a properly located sheet, including means on the support surface for holding the sheet properly located thereon wherein the sheet-holding means comprises a movable sheet-holding member, and means yieldably biasing the holding member to holding position.
Claim 5
Independent Claim
141 words
A device for printing on a sheet comprising means defining a support for the sheet, means for detecting the presence or absence of the sheet on the support, printer means operative for printing on said sheet, drive means for operating the printer, means responsive to detection of the absence of the sheet by said detecting means for rendering said printer drive means inoperative, wherein said detecting means comprises a movably mounted member engageable with a sheet properly located on the support surface, means yieldably biasing the member to a first position engaging a sheet properly located and to a second position in the absence of a properly located sheet, including means on the support surface for holding the sheet properly located thereon wherein the sheet-holding means comprises a movable sheet-holding member, and means yieldably biasing the holding member to holding position.
Claim 6
Dependent Claim
40 words
A device as defined in claim 3 wherein the sheet-holding member comprises a clamp plate, and including a solenoid connected with the clamp plate for moving the clamp plate to release position against the bias of the yieldable holding means.
Claim 7
Independent Claim
151 words
A device for printing on a sheet comprising means defining a support for the sheet, means for detecting the presence or absence of the sheet on the support, printer means operative for printing on said sheet, drive means for operating the printer, means responsive to detection of the absence of the sheet by said detecting means for rendering said printer drive means inoperative, means mounting the printer for reciprocal movement between a printing position overlying the sheet support surface and a withdrawn position exposing the sheet support surface, wherein said detecting means comprises a movably mounted member engageable with a sheet properly located on the support surface, means yieldably biasing the member to a first position engaging a sheet properly located and to a second position in the absence of a properly located sheet, including a switch device operably operable by the detecting member in one position for controlling the printer.
Claim 8
Independent Claim
151 words
A device for printing on a sheet comprising means defining a support for the sheet, means for detecting the presence or absence of the sheet on the support, printer means operative for printing on said sheet, drive means for operating the printer, means responsive to detection of the absence of the sheet by said detecting means for rendering said printer drive means inoperative, means mounting the printer for reciprocal movement between a printing position overlying the sheet support surface and a withdrawn position exposing the sheet support surface, wherein said detecting means comprises a movably mounted member engageable with a sheet properly located on the support surface, means yieldably biasing the member to a first position engaging a sheet properly located and to a second position in the absence of a properly located sheet, including a switch device operably operable by the detecting member in one position for controlling the printer.
Claim 9
Dependent Claim
38 words
A device as defined in claim 5, including means on the support surface for holding the sheet properly located therein thereon in position for printing, and means responsive to movement of the printer for operating the sheet-holding means.
Claim 10
Dependent Claim
35 words
A device as defined in claim 6, wherein the sheet-holding means comprises a clamp member, and including means responsive to movement of the printer to retracted position for moving the clamp member to release position.
Claim 11
Dependent Claim
35 words
A device as defined in claim 6, wherein the sheet-holding means comprises a clamp member and including means responsive to movement of the printer to printing position for moving the clamp member to clamp position.
Claim 12
Dependent Claim
40 words
A device as defined in claim 3, including means providing an aperture in the sheet-holding member positioned when the holding member is in holding position to receive the detecting member when no sheet is properly located on the support surface.
