Abstract: A circular sawing machine having a hidden-type infrared guide device includes a main frame, a saw base pivotally mounted on the main frame, an infrared guide device, and an operation set. The infrared guide device is mounted on the saw base and includes a slide slidably mounted on the saw base, and an infrared indication lamp mounted on the slide. The slide is formed with an elongated slot. The operation set is mounted on the infrared guide device, and includes a drive plate, a movable pin, and an elastic plate. The movable pin is extended through the elongated slot of the slide and has a first end pivoted with the drive plate, and a second end combined with the elastic plate. The elastic plate is mounted on the movable pin and rested on the slide.

Abstract: A method and apparatus for providing a guide for use with rotary components such as a rotary saw. In the preferred embodiment the invention is comprised of a rotary saw with a blade, a reflector affixed adjacent and coaxial to said blade, a light beam source, preferably a laser projecting a beam of light co-planer to and at said reflector. The reflector acts as a curved mirror to fan the beam of light creating a guideline coplanar with the rotary component or blade of the rotary saw.

Abstract: An optical system mounted on a cutter that has a base and a housing supporting a blade. In one embodiment, the optical system may projects first and second indicator lines on the base. The optical system may also include a mechanism selectively operable to adjust the first and second lines to indicate the width of the blade.

Abstract: Tool elements and methods. In some constructions and in some aspects, a tool element includes a main body and an indicator positioned on the main body for indicating the position of the tool element relative to a workpiece. In some constructions and in some aspects, a tool element is useable with a power tool, which has a guide. The tool element includes a main body connectable to the power tool and an indicator positioned on the main body for indicating the position of the guide relative to the workpiece. In some constructions and in some aspects, a method of manufacturing a tool element includes providing the tool element and producing an indicator on the tool element for indicating the position of the tool element relative to a workpiece.

Abstract: A magnetic cutting board-template combination as disclosed for cutting paper into desired designs or drawing designs on the paper. The cutting board is preferably formed from a ferrous metal and the template is formed from a magnetic material so as to hold the paper to the cutting surface while the cut is performed.

Abstract: A method for use with a power saw having a frame with a first blade rotatably mounted thereon, the first blade having a cutting edge with a maximum first thickness. A light source is mounted on the frame. An opaque barrier has a first slot with a first width. The opaque barrier is positioned in alignment with the light source such that light from the light source passes through the first slot and shines on the first blade so as to produce a shadow of the first blade. The method includes exchanging the first blade with a second blade, the second blade having a maximum second thickness. The opaque barrier is adjusted such that the first slot is replaced with a second slot having a second width, the second width of the second slot being greater than or smaller than the first width of the first slot.

Abstract: A circular sawing machine includes a work table, a saw seat having a first end provided with a saw blade and a second end pivotally mounted the work table, and an indication device mounted on the saw seat. The indication device includes a support seat secured on the saw seat, a slide seat mounted on the support seat, and an indication light source mounted on the slide seat.

Abstract: A kerf indicator for use with a power saw provides a source of light directed towards a blade of the saw. The light passes through a plurality of slots in an opaque barrier member. The barrier member planarizes the light such that a shadow of the saw blade is cast on a workpiece accurately indicating the location and width of a kerf, or cutting path, to be produced by the saw blade on the workpiece.

Abstract: A cutter including a base, a holder, a cutter blade portion, and a laser generator. The holder is supported on the base portion in an upright posture. The cutter blade portion supports a moving blade. The cutter blade portion is supported on the holder movable between an upper position and a lower position. The cutter blade portion is moved into the lower position to cut a workpiece supported on the base using the moving blade. The laser generator is attached to the holder or the cutter blade portion in an orientation to direct at least a portion of the laser light onto a position on the workpiece that is directly beneath the cutter blade portion when the cutter blade portion is in the upper position. Alternatively, a holder has a shaft support portion, and a slide shaft is axially slidably supported by the shaft support portion. A front end of the slide shaft has a hinge holder which pivotally supports the cutting blade portion. A laser generator is fixed to a front side of the hinge holder.

Abstract: An optical unit for projecting an image including first and second locating lines for substantially eliminating the introduction of visual parallax error. In one preferred form, the optical unit is incorporated into a machine for performing a forming operation on a workpiece and is operative to project an image of a portion of a scale to a position easily read by the user during machine operation. The optical unit includes a prism portion having a first side disposed adjacent the scale, a second side at an angle to the first side for reflecting the image and a third side through which the projected image may be viewed. The first locating line is disposed on the first side and the second locating line is disposed on the third side such that visual alignment eliminates the introduction of visual parallax error associated with reading a scale.

Abstract: Image data representing an image to be printed is captured, and a cutting pattern for cutting the outer form of an image printed on recording paper is selected from a plurality of different cutting patterns. In accordance with the captured image data, one or more images are printed on the recording paper in sizes and layout proper for the selected cutting pattern. Then, the outer forms of one or more images are cut on the recording paper in the selected cutting pattern. This eliminates the necessity of entering the size and layout of the image to be printed on the recording paper and editing a cutting method. Moreover, one or more images can be printed on the recording paper in a desired size and layout, and the outer forms of one or more images are cut on the recording paper in a desired cutting pattern.
