Printing apparatus
A printing apparatus is provided with a moving body moving while holding a can body; an image forming unit forming an image on the can body on the moving body stopped at a predetermined stop location; and a pressed part installed at the stop location, at least one of a portion of the moving body stopped at the stop location and a portion of the can body held by the moving body being pressed against the pressed part. Thus, positioning precision of the can body in stopping the can body and performing image formation onto the can body is increased.
1. A printing apparatus comprising:
a moving body moving while holding a can body;
an image forming unit forming an image onto the can body on the moving body stopped at a predetermined stop location;
a pressed part installed at the stop location where the image is formed, at least one of a portion of the moving body stopped at the stop location and a portion of the can body held by the moving body being pressed against the pressed part; and
a biasing unit biasing at least the portion toward a side where the pressed part is provided, wherein,
when the image is formed by the image forming unit, the portion is pressed against the pressed part by the biasing unit in a state where the can body is held by the moving body.
2. The printing apparatus according to claim 1 , wherein the biasing unit biases the portion toward the side where the pressed part is provided by use of a magnetic force.
3. The printing apparatus according to claim 1 , wherein the pressed part rotates and a driving force rotating the can body is transmitted to the moving body via the pressed part and the portion.
4. The printing apparatus according to claim 1 , wherein the pressed part is disposed coaxially with the can body held by the moving body stopped at the stop location.
5. The printing apparatus according to claim 4 , wherein the pressed part is disposed coaxially with the can body, the pressed part is disposed coaxially with the can body, the pressed part also being disposed on an opening side included in the can body.
6. The printing apparatus according to claim 1 , further comprising:
a positioning unit provided to the stop location, the positioning unit performing positioning of the can body, which is held by the moving body, in a radial direction.
7. The printing apparatus according to claim 1 , further comprising:
a rotation body provided to the stop location, the rotation body being disposed coaxially with the can body held by the moving body stopped at the stop location to be used for rotating the can body; and
a phase adjustment unit provided to the stop location, the phase adjustment unit adjusting a phase of the can body held by the moving body stopped at the stop location with respect to the rotation body to a predetermined phase.
8. The printing apparatus according to claim 7 , wherein the phase adjustment unit adjusts a phase of the can body with respect to the rotation body to one predetermined phase.
9. The printing apparatus according to claim 1 , wherein the moving body is not provided with a motor used to rotate the can body held by the moving body.
10. A printing apparatus comprising:
a moving body moving while holding a can body;
an image forming unit forming an image on the can body on the moving body stopped at a predetermined stop location; and
a pressing part installed at the stop location where the image is formed, the pressing part being pressed against at least one of a portion of the moving body stopped at the stop location and a portion of the can body held by the moving body, wherein
the pressing part is pressed against the portion in a state where the can body is held by the moving body.
