摘要:
Conveyance of a sheet in an inkjet recording apparatus may be stopped under various conditions. In one example, a control device of the inkjet recording apparatus may stop conveyance on the sheet depending on the image to be formed in one or more portions of the sheet. Alternatively or additionally, conveyance may be stopped based on an amount of ink ejected or to be ejected onto a sheet, or portion thereof. The conveyance stoppage control may be used in conjunction with a corrugate mechanism in some arrangements.
摘要:
There is provided an ink-jet recording apparatus including: a first transporting portion provided in a first transport path; a support member configured to support the sheet; a recording portion; a plurality of contact portions configured to come into contact with the sheet; a plurality of support ribs; a second transporting portion provided in a second transport path connected with the first transport path; and a third transporting portion configured to sandwich and transport the sheet in the first transporting direction or toward the second transport path. On the upstream side to the second transporting portion in the second transporting direction, a projecting portion is formed with the upper guide member to project toward the lower guide member below a virtual line linking a nip position of the sheet due to the third transporting portion with another nip position of the sheet due to the second transporting portion.
摘要:
An inkjet recording apparatus may include a corrugate mechanism configured to form a sheet into a corrugated shape. The inkjet recording apparatus may be configured to receive sheets of various sizes and shapes. Accordingly, in some examples, the inkjet recording apparatus may include differently configured portions to handle sheets of different sizes or shapes. According to one arrangement, the inkjet recording apparatus may be configured to receive passage of sheets of a first size through multiple ones of the differently configured portions while receiving passage of sheets of a second size though limited ones of the differently configured portions.
摘要:
An electronic part mounting apparatus includes a chamber for cleaning a substrate and an electronic part by plasma, amounting mechanism for mounting the electronic part on the electronic part, and a conveying robot for conveying the substrate and the electronic part from the chamber to the mounting mechanism. After plasma cleaned, the substrate and the electronic part are swiftly conveyed to the mounting mechanism by the conveying robot. After the electronic part is mounted on the substrate by the mounting mechanism, the resultant combination of them is pulse heated. Therefore, the electronic part is appropriately mounted on the substrate in a state that those are exposed to the air. A part mounting mechanism is simplified.
