Japanese Patent Laid-Open No. 10-54147 Registered utility model No. 3021476

  The technique using a dedicated grid ruler having the same size as the plate surface described above is very inconvenient because the ruler size is extremely large and the burden of various handling such as storage, movement, and use is large. On the other hand, the roller stamp technology described above has the following problems. That is, since a certain skill is required to move the roller straight on the plate surface, it is not always easy to accurately mark the striking position in the direction perpendicular to the moving direction of the roller using such a roller stamp. In addition, it is necessary to replenish the stamp ink with the stamp every time it is used, or it is necessary to store it in the cover to avoid unintended ink adhesion when not in use. Absent.

  Then, this invention makes it a subject to provide the fixing tool hitting position marking apparatus which can mark the hitting position of a fixing tool correctly, while being easy to handle.

  In order to achieve the above object, the present invention provides a fixture hitting position marking device including a ruler portion and a moving portion mounted on the ruler portion so as to be movable in the extending direction of the ruler portion. Here, the moving unit includes a holding unit that holds a writing instrument, and a roller that is rotatably supported with an axis parallel to the extending direction of the ruler unit as a rotation axis. The cross-sectional shape in the direction perpendicular to the rotation axis has a non-circular shape. And the writing instrument held by the holding part has a position where the pen point of the writing part comes into contact with the plate surface as the roller rotates on the plate surface of the plate material, and the pen point of the writing part is the plate. It vibrates between positions away from the surface.

  According to such a fixing tool striking position marking device, the roller is brought into contact with the plate surface, and the fixing tool striking position marking device is simply moved along the side surface of the plate material. A broken line in which the lines are interrupted at a constant interval or a broken line in which the lines are drawn at a constant interval extending in the extending direction of the side surface is drawn on the plate surface at a certain distance from the side surface.

  Therefore, when the plate member is fixed, it becomes possible to easily grasp and determine the fixing position of the fixing tool at a desired interval with reference to the broken part of the broken line or the part where the line is drawn. Further, such a fixing tool striking position marking device can be downsized to approximately a ruler size and does not require labor such as replenishment of ink, so that it can be handled easily.

  In order to achieve the above object, the present invention provides a fixture hitting position marking device provided with a ruler part and a moving part mounted on the ruler part so as to be movable in the extending direction of the ruler part. To do. Here, the moving unit includes a holding unit that holds the writing instrument, a roller that is rotatably supported around an axis parallel to the extending direction of the ruler unit, and a writing instrument moving mechanism. As the roller rotates on the plate surface of the plate material, the moving mechanism is configured such that the writing tool held by the holding unit has a position where the pen point of the writing unit is in contact with the plate surface, and the pen point of the writing unit is It vibrates between a position away from the plate surface.

  The writing unit moving mechanism may be configured using a cam that rotates with the rotation of the roller and causes the writing tool held by the holding unit to perform the vibration, or may be held by the holding unit. A solenoid for changing the position of the writing instrument when the supplied power is supplied, and a switch for switching on / off of power supply to the solenoid, which repeatedly changes between an on state and an off state as the roller rotates. can do.

  According to these fixing tool striking position marking devices, the roller is brought into contact with the plate surface of the plate material, and the fixing tool striking position marking device is moved easily along the side surface of the plate material. A broken line in which the lines are interrupted at regular intervals or a broken line in which the lines are drawn at regular intervals is drawn on the plate surface at a certain distance from the side surface. Further, since a roller having a perfect circle shape can be used, a broken line can be drawn more smoothly on the plate surface.

  Here, in each of the above-mentioned fixing tool hitting position marking devices, it is preferable to provide a scale indicating the length in the ruler portion. Moreover, it is preferable that an arbitrary number of the moving parts can be attached to the ruler part. By providing a plurality of moving parts, a desired number of broken lines separated by a desired distance can be drawn by a single fixing tool striking position marking device.

  Further, in each of the fixing tool hitting position marking devices described above, the movement of the ruler portion along the side surface of the plate member is guided while being in contact with the side surface of the plate member fixed to one end of the ruler portion. Providing a guide portion is also preferable in order to accurately draw a broken line at a position away from the side surface of the plate material by a desired distance.
