Abstract
Description
Technology Field
[0001] The present invention relates to a marking felt-tip pen, and more specifically, to a marking felt-tip pen with integrated writing and stamping functions that enables a user to mark answer sheets quickly and accurately in multiple-choice exams such as the College Scholastic Ability Test and the TOEIC exam. The present invention falls under the technical field of writing instruments and marking tools. Background Technology
[0002] Conventional computer felt-tip pens required marking with a nib, so marking consumed a considerable amount of time.
[0003] It was devised with the idea of shortening this time and using it for problem-solving. The problem to be solved
[0004] The purpose of this invention is to shorten the time required for using computer-compatible felt-tip pens in the College Scholastic Ability Test or the TOEIC exam. means of solving the problem
[0005] Stamp-style Cap: The pen cap features a built-in stamp plate and ink pad, designed for easy use during stamping operations. The rounded tip of the cap allows for a stable grip and helps apply pressure evenly to the surface when stamping.
[0006] Ink Pad Protective Cap: Includes an inner cap that seals the ink pad and protects them to prevent the ink from drying out.
[0007] Basically, the pen body performs the writing function in the same way as a conventional marking pen.
[0008] If necessary, open the lid and use the paint-type module. Effects of the invention
[0009] Switching between stamp and writing functions is easy, and there is a marking stamp with a pen nib and stamp-type technology that can save time when marking. Brief explanation of the drawing
[0010] Fig. 1 is a design drawing of the product. Specific details for implementing the invention
[0011] The present invention will be described in detail below with reference to the attached drawings.
[0012] Double-sided structure: Based on a single body, it is designed with a standard writing nib at one end and a stamp-type marking function integrated at the other. The body uses a lightweight yet highly durable plastic material.
[0013] Writing pen nib
[0014] Nib and Ink Reservoir: Structured identically to a standard marking pen, it uses a nib suitable for writing numbers or text on multiple-choice answer sheets and fast-drying ink.
[0015] The ink adopts a density and color (e.g., black or dark blue) that is easily recognized by multiple-choice test answer sheet scanners.
[0016] Stamp-type marking part
[0017] Stamp plate: A circular stamp plate is embedded at the other end, and is designed in size (diameter approximately 5 to 7 mm) to fit the selection box (e.g., circular, square) on the test paper.
[0018] Ink Pad: An internal ink pad is inserted into the stamp plate to ensure even ink application, and it has sufficient capacity to prevent ink shortage during use.
[0019] Lid structure: The stamp-type marking part is designed with a sealed lid to prevent and protect the ink from drying when not in use.
[0020] Writing pen assembly: Assemble the nib and ink reservoir of a standard marking pen at one end.
[0021] Assembly of the stamp-type marking section: Assemble the stamp plate and ink pad at the other end, and additionally attach a sealed lid.
[0022] It is expected that integrating writing and marking functions into a single tool will reduce marking time and make it easier to write names as it also allows for handwriting.
Claims
Claim 1 A marking pen having a double-sided structure, wherein a writing nib for writing numbers on a multiple-choice answer sheet and general writing is positioned at one end, and a stamp-type marking section designed to quickly mark the selection box of a multiple-choice answer sheet is positioned at the other end. The stamp-type marking section includes a stamp plate and an internal ink pad, and is characterized by having a sealed cap to prevent the ink from drying out when not in use. Claim 2 A marking pen according to claim 1, characterized in that the stamp plate is designed in a circular shape that fits the size of the selection box on the test answer sheet, and the ink pad is configured to be in close contact with the stamp plate so that ink is delivered uniformly. Claim 3 A marking pen according to claim 1, characterized in that the sealed lid includes an ink pad protection structure inside, and is configured such that when the lid is closed after use, the ink pad is completely sealed to prevent the ink from drying out even during prolonged use.
