Abstract

A printing apparatus includes, an outer jig comprising an outer wall portion and a recessed portion, an inner jig disposed in the recessed portion and forming a hole between the outer wall portion and the inner jig, and a print head comprising a pad portion configured to overlap the hole, wherein the outer jig comprises an outer coupling portion disposed adjacent to a first surface of the outer jig facing the inner jig, the inner jig comprises an inner coupling portion disposed adjacent to a second surface of the inner jig facing the outer jig, and the outer jig and the inner jig are detachable from each other by detachment of the outer coupling portion and the inner coupling portion from each other.

First claim

What is claimed is:

1 . A printing apparatus comprising:
an outer jig comprising an outer wall portion and a recessed portion; an inner jig disposed in the recessed portion and forming a hole between the outer wall portion and the inner jig; and a print head comprising a pad portion configured to overlap the hole, wherein the outer jig comprises an outer coupling portion disposed adjacent to a first surface of the outer jig facing the inner jig, the inner jig comprises an inner coupling portion disposed adjacent to a second surface of the inner jig facing the outer jig, the outer jig and the inner jig are detachable from each other by detachment of the outer coupling portion and the inner coupling portion from each other, the outer coupling portion is located inside the outer jig, the inner coupling portion is located inside the inner jig, and the outer coupling portion and the inner coupling portion are spaced apart from each other in a state where the outer jig and the inner jig are coupled to each other.

2 . The printing apparatus of claim 1 , wherein a size of the recessed portion is larger than a size of the inner jig in plan view.

3 . The printing apparatus of claim 1 , wherein the outer coupling portion and the inner coupling portion respectively comprise magnets having different polarities.

4 . The printing apparatus of claim 1 , wherein at least one of the outer coupling portion or the inner coupling portion comprises a magnet.

5 . The printing apparatus of claim 4 , wherein the magnet is a ferromagnetic material.

6 . The printing apparatus of claim 1 , wherein the pad portion is formed in a rectangular parallelepiped shape in plan view configured to be inserted into the hole to print ink on a plurality of surfaces of an object disposed on the inner jig.

7 . The printing apparatus of claim 1 , wherein the pad portion is formed of an elastic material having a shape corresponding to the hole in plan view and that is deformable to contact a plurality of surfaces of an object disposed on the inner jig.

8 . The printing apparatus of claim 1 ,
wherein the inner jig comprises: a support portion comprising a flat surface; and a plurality of side portions and a plurality of corner portions, surrounding the support portion and disposed adjacent to the support portion, and wherein upper surfaces of the plurality of side portions and the plurality of corner portions are curved surfaces.

9 . The printing apparatus of claim 8 , wherein the pad portion has a same shape as a shape formed by the plurality of side portions and the plurality of corner portions in plan view.

10 . The printing apparatus of claim 1 , wherein
the print head further comprises a head body, wherein the pad portion is disposed on the print head, and the pad portion comprises an opening exposing the head body.

11 . A method of manufacturing a window member using a printing apparatus, the method comprising:
coupling an inner jig to an outer jig forming a hole between the outer jig and the inner jig; placing the window member on the inner jig coupled to the outer jig; aligning a pad portion with the hole, wherein an ink is applied to the pad portion; and printing the ink on the window member by moving the pad portion.

12 . The method of claim 11 , wherein the ink comprises a light blocking material and the method further comprises hardening the ink on the window member to form a light blocking portion.

13 . The method of claim 11 , further comprising preparing the window member and the inner jig compatible with the window member, wherein
the inner jig comprises a support portion comprising a flat surface, and a plurality of side portions and a plurality of corner portions surrounding the support portion and disposed adjacent to the support portion, the window member comprises a flat portion, a bending portion surrounding the flat portion and located on a side of the flat portion, and an outer side surface surrounding the bending portion and located on a side of the bending portion, and in the placing of the window member on the inner jig, an outer periphery of the flat portion of the window member is disposed inside an outer periphery of the support portion of the inner jig.

14 . The method of claim 13 , wherein an area of the flat portion of the window member is smaller than an area of the support portion of the inner jig.

15 . The method of claim 13 , wherein in the aligning of the pad portion with the hole, the pad portion overlaps at least a portion of the flat portion of the window member.

16 . A printing apparatus comprising:
an outer jig comprising a recessed portion and an outer coupling portion disposed adjacent to a first surface of the outer jig; an inner jig detachably coupled to the outer jig and comprising an inner coupling portion disposed adjacent to a second surface of the inner jig facing the outer jig and having a curved shape at side portions thereof, and a print head comprising a pad portion, the pad portion comprising a portion overlapping the side portions of the inner jig, wherein the outer coupling portion is located inside the outer jig, the inner coupling portion is located inside the inner jig, and the outer coupling portion and the inner coupling portion are spaced apart from each other in a state where the outer jig and the inner jig are coupled to each other.
