Tray for ink jet printer and method of manufacturing golf ball having mark
View Patent ↗A tray 2 includes a holder 10 into which a golf ball is to be set. The holder 10 has: in an upper surface thereof and a lower surface thereof, openings 46 and 48 from which parts of the golf ball are exposed, respectively; and a contact portion 52 that comes into contact with the golf ball to fix in place the golf ball. The holder 10 is invertible. Preferably, the tray 2 further includes a base plate 12 on which the holder 10 is mounted. The base plate 12 has a stopper 72 that comes into contact with the golf ball set into the holder 10 . The golf ball is fixed to the holder 10 such that the position of the center of the golf ball is caused to agree with the position of the center of the holder 10 in a thickness direction thereof due to this contact.
1. A tray for an ink jet printer, the tray comprising:
a holder into which a golf ball is set, wherein
the holder has: an upper surface with an opening from which a part of the golf ball is exposed; a lower surface with another opening from which another part of the golf ball is exposed; and an inner surface that surrounds the set golf ball with a contact portion that comes into contact with the golf ball to fix in place the golf ball, the contact portion projecting inwardly from the inner surface, and wherein
the holder is invertible.
2. The tray according to claim 1 , wherein the contact portion has a height of 0.3 mm or greater and 0.8 mm or less.
3. The tray according to claim 1 , wherein the contact portion is located so as to extend along a great circle of the set golf ball.
4. The tray according to claim 1 , wherein the contact portion is made of a ring-shaped member.
5. The tray according to claim 4 , wherein the contact portion has a diameter of 42.00 mm or greater and 42.20 mm or less.
6. The tray according to claim 1 , wherein the contact portion is an elastic body.
7. The tray according to claim 6 , wherein the contact portion has a hardness of 40 or greater and 70 or less.
8. The tray according to claim 1 , wherein a center of the contact portion in a thickness direction thereof is located at a position of a center of the holder in a thickness direction thereof.
9. The tray according to claim 8 , wherein the contact portion has a thickness of 2.90 mm or greater and 3.00 mm or less.
10. The tray according to claim 1 , further comprising a base plate on which the holder is mounted, wherein
the base plate has a stopper that comes into contact with the golf ball that has been set into the holder, and
the golf ball is fixed to the holder such that a position of a center of the golf ball is caused to agree with a position of a center of the holder in a thickness direction thereof due to this contact.
11. The tray according to claim 10 , wherein the stopper is a tapered hole that is shaped so as to be tapered downwardly.
12. The tray according to claim 10 , further comprising a clamp capable of fixing the holder to the base plate.
13. A method of manufacturing a golf ball having a mark, the method comprising the steps of:
putting a golf ball in a holder that has: an upper surface with a first opening that exposes a part of the golf ball; a lower surface with a second opening that exposes another part of the golf ball; and an inner surface that surrounds the set golf ball with an inwardly projecting contact portion to fix the golf ball to the holder;
supplying the holder to an ink jet printer and printing a mark at the part of the golf ball exposed by the first opening of the holder;
inverting the holder with the golf ball, on which the mark has been printed, being fixed thereto; and
printing a mark at the part of the golf ball exposed by the second opening of the holder, by using the ink jet printer.
