Embodiment approach 1

[0042] (1) Outline of the overall structure of the printing device (refer to figure 1 as well as figure 2 )

[0043] The printing device 1 of the present invention has: a printing unit 5, which prints on the printing surface 3 of the medium M; a transport unit 11, which transports the medium M along the transport direction F; a medium support surface 4, which is located in the transport direction F relative to the printing unit 5 Upstream + F, supports the medium M; the pretreatment unit 17 preprocesses the medium M supported by the medium support surface 4; and the assembly unit 50 is located opposite to the medium support surface 4, and the pretreatment unit 17 is detachable Attached to the mounting part 50 .

[0044] Furthermore, the mounting unit 50 has a position limiting mechanism 37 that limits the position of the preprocessing unit 17 relative to the medium supporting surface 4 when the preprocessing unit 17 is mounted.

[0045] The illustrated printing device 1A i...

Embodiment approach 2

[0081] Implementation mode two (refer to Figure 6 )

[0082] Next, based on Figure 6 The structure, function, and effect of the printing apparatus 1C according to the second embodiment of the present invention, which is partially different from the structure of the embodiment, will be described.

[0083] The printing device 1C according to the second embodiment is a so-called printing and dyeing device that performs printing on the fabric N, and performs processing for smoothing fluff peculiar to the fabric N by the preprocessing unit 17 .

[0084] Therefore, description of the same configuration as that of the first embodiment is omitted here, and the description will focus on the configuration unique to this embodiment, which is different from the first embodiment, that is, a configuration specific to a printing and dyeing device that performs printing on the fabric N.

[0085] The printing apparatus 1C according to this embodiment includes: a printing unit 5 for printin...

Abstract

The invention discloses a printing apparatus. The printing apparatus enables the dismounting operation of a preprocessing portion to be easily carried out, and enables the preprocessing portion to berepeatedly assembled at an optimal position capable of fully exerting the performance. The printing apparatus includes a printing portion (5) configured to perform printing on a printing surface (3) of a medium (M), a transporting portion (11) configured to transport the medium (M) in a transport direction (F), a medium supporting plane (4) located upstream (+F) of the printing portion (5) in thetransport direction (F) and configured to support the medium (M), a preprocessing portion (17) configured to perform preprocessing on the medium (M) supported by the medium supporting surface (4), anda mount portion (50) facing the medium supporting surface (4), the mount portion being configured such that the preprocessing portion (17) is detachably mounted thereto. The mount portion (50) includes a position-setting mechanism (37) configured to set a position of the preprocessing portion (17) with respect to the medium supporting surface (4).

Description

technical field [0001] The present invention relates to printing devices. Background technique [0002] Patent Document 1 discloses that a preprocessing unit that removes foreign matter such as dust and fluff adhering to a printing surface of a medium is detachable from a fixed unit. In this way, maintenance is performed to restore the pretreatment ability, which is the foreign matter removal ability of the pretreatment unit. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2017-197354 [0004] However, there are the following problems in the above structure. That is, the preprocessing capability of the preprocessing unit changes according to the position of the preprocessing unit with respect to the medium and the medium support unit. In the above configuration, when the pre-processing unit is attached to or detached from the fixing unit, the position of the pre-processing unit with respect to the fixing unit may change. Contents of the invention [0005] The...
