Abstract

According to one embodiment, a mobile printer includes a first housing, a second housing, a hinge, and a print head. The first housing has a first surface on which a printing medium can be disposed. The second housing faces the first surface. The hinge connects the first housing and the second housing and permits the first and second housings to rotate relative to each other. The print head is provided in the second housing and is configured to print an image by discharging on to the print medium when the print medium is on the first surface between the first and second housings.

First claim

What is claimed is:

1. A mobile printer, comprising:
a first housing with a first surface;
a second housing with a second surface;
a hinge to connect the first housing and the second housing and configured to permit the first housing and the second housing to rotate relative to each other between a closed position and an open position, the first and second surfaces facing each other in the closed position; and
a print head in the second housing at the second surface and configured to print an image on a print medium while the print medium is supported on the first surface and held between the first and second surfaces with first and second housings at the closed position.

2. The mobile printer according to claim 1 , further comprising:
a position detection sensor configured to detect relative movement between the first housing and the second housing on the hinge.

3. The mobile printer according to claim 1 , further comprising:
a position detection sensor configured to detect when the first housing and the second housing are in the closed position.

4. The mobile printer according to claim 1 , further comprising:
a sensor configured to detect that the printing medium is between the first housing and the second housing when the first housing and the second housing are in the closed position.

5. The mobile printer according to claim 1 , further comprising:
a motor configured to move at least one of the first housing and the second housing about the hinge in an opening direction in which the first housing and the second housing are separated from each other and a closing direction in which the first housing and the second housing approach each other.

6. The mobile printer according to claim 1 , further comprising:
an urging member positioned to move at least one of the first housing and the second housing about the hinge in an opening direction.

7. The mobile printer according to claim 1 , wherein the print head is an ink jet type print head.

8. The mobile printer according to claim 1 , wherein the hinge is formed of a piece of the first housing and a piece of the second housing connected to one another.

9. The mobile printer according to claim 1 , wherein the hinge includes a shaft extending through at least one of the first housing and the second housing.

10. The mobile printer according to claim 1 , wherein the first housing can be disconnected from the second housing.

11. The mobile printer according to claim 1 , wherein the print head holds decolorable ink therein.

12. The mobile printer according to claim 1 , further comprising:
a plurality of user input units on the second housing.

13. A mobile printer, comprising:
a first housing with a first surface;
a second housing with a second surface configured to face the first surface of the first housing; and
a print head in the second housing configured to print an image on a print medium supported on the first surface while the print medium is sandwiched between the first and second surfaces in a facing arrangement.

14. The mobile printer according to claim 13 , further comprising:
a position sensor configured to detect when the second surface of the second housing is in a position facing the first surface; and
a print medium sensor configured to detect when the print medium is between the first and second surfaces in the facing arrangement.

15. The mobile printer according to claim 14 , wherein the print head is configured to print an image on the print medium only when both the position sensor detects the second surface is in the position facing the first surface and the print medium sensor detects the print medium is between the first and second surfaces.

16. The mobile printer according to claim 13 , wherein the first housing is configured to connect to second housing at a hinge permitting the first housing and the second housing to rotate relative to each other.

17. The mobile printer according to claim 16 , further comprising:
a motor configured to move at least one of the first housing and the second housing about the hinge in an opening direction in which the first housing and the second housing are separated from each other and a closing direction in which the first housing and the second housing approach each other.

18. The mobile printer according to claim 16 , further comprising:
an urging member positioned to move at least one of the first housing and the second housing about the hinge in an opening direction.

19. The mobile printer according to claim 13 , wherein the print head is an ink jet type print head.

20. The mobile printer according to claim 13 , wherein the print head holds decolorable ink.
