Abstract

A printer includes a lid part, a body part, a first rotating shaft, a second rotating shaft, a first engaging part having the first rotating shaft removably engaged therewith so as to allow the lid part to be opened and closed relative to the body part, and a second engaging part receiving the second rotating shaft in such a manner as to allow the second rotating shaft to rotate. In response to application of a first predetermined force, the first rotating shaft is removed from the first engaging part while absorbing a second predetermined force from the first predetermined force, and the lid part is allowed to rotate on the second rotating shaft to be opened and closed relative to the body part.

First claim

What is claimed is:

1. A printer, comprising:
a lid part;
a body part;
a first rotating shaft;
a second rotating shaft;
a first engaging part having the first rotating shaft removably engaged therewith so as to allow the lid part to be opened and closed relative to the body part; and
a second engaging part receiving the second rotating shaft in such a manner as to allow the second rotating shaft to rotate,
wherein in response to application of a first predetermined force, the first rotating shaft is removed from the first engaging part while absorbing a second predetermined force from the first predetermined force, and the lid part is allowed to rotate on the second rotating shaft to be opened and closed relative to the body part.

2. The printer as claimed in claim 1 , further comprising:
one or more third rotating shafts provided between the first rotating shaft and the second rotating shaft; and
one or more third engaging parts provided between the first engaging part and the second engaging part and having the corresponding one or more third rotating shafts removably and rotatably engaged therewith,
wherein in response to application of a third predetermined force greater than the first predetermined force, the one or more third rotating shafts are successively removed from the corresponding one or more third engaging parts, with one of the one or more third rotating shafts closest to the first rotating shaft being removed first, while absorbing a fourth predetermined force from the third predetermined force, the fourth predetermined force being greater than the second predetermined force.

3. A printer, comprising:
a body part;
a lid part configured to be opened and closed relative to the body part;
a paper housing part configured to house paper;
a control part provided in the body part;
a mark detecting part movably provided in the body part and configured to detect a mark added to the paper in a paper conveyance path, the mark detecting part is movable between a detection-enabled position where the mark detecting part is configured to detect the mark, and a non-detection-enabled position where the mark detecting part is moved out of the paper conveyance path, the paper conveyance path being a path through which the paper is conveyed;
a spring configured to urge the mark detecting part to move toward the non-detection-enabled position; and
a moving part configured to move the mark detecting part to the detection-enabled position in response to closure of the lid part, and to move the mark detecting part to the non-detection-enabled position in response to opening of the lid part;
wherein the moving part includes a holding part that is configured to move the mark detecting part to the detection-enabled position against the urging of the spring when the lid is closed, that is formed as a unit with the lid part, and that is formed to project from an inner surface of the lid part.

4. The printer as claimed in claim 3 , wherein the spring has a first end provided on the body part and a second end connected to the mark detecting part.

5. The printer as claimed in claim 4 , wherein the spring directly exerts a force on the mark detecting part so as to urge the mark detecting part to move toward the non-detection-enabled position.

6. The printer as claimed in claim 3 , wherein the spring directly exerts a force on the mark detecting part so as to urge the mark detecting part to move toward the non-detection-enabled position.

7. A printer, comprising:
a lid part;
a body part;
a rotating shaft;
an engaging part having the rotating shaft removably engaged therewith so as to allow the lid part to be opened and closed relative to the body part;
a mark detecting part provided on the lid part and configured to output a mark detection signal in response to detecting a mark added to paper;
a transmission part configured to transmit the mark detection signal from the mark detecting part to the control part; and
a connecting part,
wherein the lid part and the body part are caused to be separated from each other and the transmission part is caused to be separated into multiple portions by removal of the rotating shaft from the engaging part, and
the connecting part is configured to electrically connect the portions of the separated transmission part upon engagement of the rotating shaft with the engaging part.

8. The printer as claimed in claim 7 , wherein:
a first one of the multiple portions of the separated transmission part is provided in the lid part and has a first terminal at an end thereof, and a second one of the multiple portions of the separated transmission part is provided in the body part and has a second terminal at an end thereof, and
the connecting part is configured to urge at least one of the first terminal and the second terminal so that the first terminal and the second terminal are electrically connected upon the engagement of the rotating shaft with the engaging part.

9. The printer as claimed in claim 7 , wherein:
a first one of the multiple portions of the separated transmission part is provided in the lid part and has a first terminal at an end thereof, and a second one of the multiple portions of the separated transmission part is provided in the body part and has a second terminal at an end thereof, and
the connecting part is electrically conductive and has a first end thereof electrically connected to the first terminal, the connecting part being configured to have a second end thereof electrically connected to the second terminal upon the engagement of the rotating shaft with the engaging part.
